hello welcome everybody to uh warp stock2021 virtualcoming from the netherlands againuh we tried to put up a physical warpstock but due to the uncertainty of thecovet 19 pandemic people wanted to stayat home so we're coming here to you frommy own living room here innaikerkumlet's see here we've got a couple ofpresentations lined up for youmost of the presentations arepre-recorded however the presenters areavailableto answer questionssowe canyou can watch the presentationsand you can ask channels you can askquestions on the irc channeluh the free node network has becomelet's just say unpopularso there has been a splitumyou can use any of the two irc channelsi'm monitoring them both and i'm alsomonitoring theum theyoutubestream here if you have any questionsumoh i'm getting the response herefrom lewis that the volume seems to belowit's fine herei don't know what it is turn up thevolume sorry i'll put the mouthpiececloser to my to my mouth maybe then youcan hear me better i can see the viewmajor on the screen goingumohand alex is reporting yes it's a bitquiet butit's okay okay okay relax right okay umwell i don't have any uhpresentation for voice nothing haschangedlater this evening we will demonstratethe new auto browser running on ahigh-end new pc built just about twoweeks agoandso far voice has beencontinuing to work to distribute newscontact the media to promote os2 andwe've alsohave been working on some other projectshopefully next year we will have a warpstock europe again in frankfurt becauseit seems that currently the whole covetcan then seem to be going in the rightdirection to allow that again but fornowthe next presentationwill be lined up infive minutesi think let's see on my clock hereyeah we'll start it in aboutfive to six minutesoh yeah we can let's see oh yes umactually looking at the length of the ofthe recording first up is a presentationfrom alex tayloruh who also contributes to arca osand his presentation is on the currentstatus of uefi and a new component whichi think is another major technicalbreakthrough flow is to gpt disk layoutsupportthe video is about46 minutesbut you can see why it'sit's a demonstration of uefi running onbare metal not in a virtual machineand it's also apresentation of the gpt partitionsupport that is under development canyou start the video pleasegood daysoas some of you may recalllast year i talked about arcanoa's plansfor enabling support for uefi in arc osand i also gave a brief demonstration ofa technology proof of concept of thatsupportso now i'm going to give an update onthe state of this project and as you'llsee it's come a long way in the pastyearfirst some obligatory disclaimersif arc osis already working on your hardwarewith the traditional non-ua non-uefisupportthen you are not required to use uefiand gpe support on that hardwarewe continue to provide support fortraditional systemssecondall features functionality versioningand release plans mentioned hereare subject to change these areforward-looking statements based only onarkanoa's current internal roadmap andare not promisesor announcementsnow that that's out of the waywhat is uefiand if you didn't catch any of myprevious presentations from last year orbefore orif you've forgotten or if you just wanta refresherhere's the answer uefi basically is areplacement for the old pc bios standardas you may know the bios which wasintroduced in the earliest ibm pcs wasbasically a layer between dos and thecomputer hardwaredosdidn't really know how to operate basiccomputer hardware like disks keyboardsor display adapters the bios took careof thatthe hardware support provided by thebios of course was verygeneric and rudimentaryand as hardware grew more diverse andoperating systems grew moresophisticated the os began to take morecontrol over the hardwareand it did this byos specific device driversand still does it by os specific devicedriversalthough up untilmoderately recent times the bios wasstill providinga small handful of basic services in thebackgroundso coming back to uefiit is a modern standard which is muchmore flexible and sophisticated thanbiostraditional biosthe development of the uefi standardsstarted more than 15 years agocomputers which rely on uefi started toenter the mainstream around 2013 or sowhich not quite coincidentally iswhen microsoft released windows 8.so uefi is by no means brand new it'sbeen around for a number of yearshowever until recentlyyou didn't have to use uefi even onnewer computers if you didn't want toand the reason is something called a csmor compatibility support modulenow this is basically a module withinthe uefi bios that emulates the old biosinterfacenote that i saiduntil recentlybecause hardware manufacturers have nowstarted phasing out csm support in theirnewest computers and system boardsand this is where it becomesan important issue for os2 usersmore and more uefi hardware is comingout which has no csm and therefore nobios compatibilityintel for example officially ended csmsupport on january 21st of 2020why thenwellbasically because that's when windows 7went out of supportthat was the last version of windowsthat used bios support by defaultnow most hardware vendors have nofurther incentive to maintain csmsupport andmost vendors have no reason to test itso what that means is with every monththat goes by it becomes harder to findnew systems with csm support andtherefore with traditional bioscompatibilitywhat does that meanfor os2wellos2 uses a few bios services mainlyinten as it's called for vga hardwareaccess and another called int 13 forgeneric disk ioand a large part of developing uefisupport for arca os has involvedcircumventing these dependenciesfortunatelythe list of these dependencies is notterribly longnow on a slight side note hereone issue that we've seen over the pastseveral years is various bios basedsystemswhere doswindowed sessions and seamless windows 2sessionsdon't workand anybody who has seen the errormessagethis system does not support thissession's video mode in a windowwe'll know what i meanwhat this basically means is that thevideo bios doesn't provide the supportthat os2 expectsso i bring this up to illustrate thattraditional bios compatibility on modernsystemsis not without its problems even whenthe csm is providedso the state of uefi supportnow it is still being improved but atthe moment as of now the uefi support inarka os is quite solidjust a list of somemajor points here we can boot from dvdwe can boot from usbhard disk usb stick whatever and we canboot from an internal hard diskwe have high resolution video supportworking althoughat present only the panorama driver issupportedwe have dosand windows 2 support working includingboth full screen and windowed sessionsand as kind of a nice bonuswe have full color boot logoswhich i must say look a lot nicer thanthe old 16 color vga logoand we also have memory dump which is tosay ring zero or trap dump supportwhich is also important especially fordevelopersnowcompared to my last warp stockpresentation on this subject dos supportunder uefi has seen major improvementsin particulara lot of dos applications are nowrunning with good performance includingquite a few games and games are animportant yardstick because they tend topush the limits of dos harder than otherapplications and for this reason i'll beshowing off several games when i runningunder dos with uefi support when i do mydemonstration in a bitand one reason that this is possiblethisdos support is that our uefi subsystemtakes over the video services that fullscreen dos relies on andwhich used to be provided by the biosand providing this essentially emulationlayer this gives us a lot more controlover that support over thatespecially the video supportand with more control comes moreconsistencyandthe ability tocontinue improving itnowfor most of the pc's historyhard disks were set up using fdisk orlvmby laying it out into primary orextended partitions which are defined inthe master boot recordthis is known as mbr disk layoutmbr has evolved a lot over the years andits capabilities have been repeatedlyextended during that timebut mostly through a whole lot ofpledges and compromisesthis has caused os2 usersa lot of headaches at least when tryingto install on a computer alongsideanother os like linux or windowsgetting os2 to coexist with these otheroperating systemshas involved an ever growing laundrylist of requirements instructionscaveats and limitationssome of this is a result of the inherentlimitations of mbrbut another issueis that lvmlike fdisk before itishighly intolerant of anythingin the disk layout that it considersimproperand you mayencounter you may have encounteredsome of these issues during installcylinder alignment errorscorrupt partition table errorsgeometry problems when movinga disk image to a different sized harddiskcertain linux distributions destroyingthe extended partition containerand of coursetrying to use a hard disk larger than512 gigabytes which already has windowsinstalled on ityeah that one was a lot of funand finallysystems nowadaysare shipped with disks formatted usinggptwhich isn't compatible at allup until now the only solution was towipe the diskand completely reformat it using mbr orelseignore the disk entirely and justinstall a secondary disk for os2and that is not always easy depending onwhat kind of system you havesowhat is gptwell it's short for guid partition tableand similar to how uefi is a replacementfor traditional bios gpt is areplacement for mbr disk layoutand gpt is actually defined in the uefistandardalthough you can have uefi without gptand vice versathe default assumption of most hardwareand software manufacturers is that uefiand gpt go together as kind of a matchedsetnow from a technical standpointgpt objectively has a lot to recommendit it supports hard disks larger thantwo terabytesit eliminates the old cylinder headsector type of addressing which gets ridin turn of a host of geometry problemsthe whole thing of having extendedversus logical partitions is a thing ofthe past extended and logical versusprimary partitions is a thing of thepastand uh in fact disks now can have asmany as 128 partitions at least andpossibly even moreandthere is actually one other importantthing about gptarkanoi now has gpt support working onarca osyou see everything listedon the bottom half of this slidewe can now take advantage of thesebenefits on arc osbut that's not allyou see everything listed on the tophalf of this slidebasicallyour new gpt drivereliminates all of these problems as wellwhen used with a gpt disksohow does our gpt support workwell we have what's called a filterdriverthat talksto the storage controller drivershci nvme etcthis filter driver reads the attachedhard drivesand it understands the gpt disk layoutit performs real-time translation inturn to present gpt partitions to theos2 storage management subsystem so thatthey look to it like mbr formatted disksnowto help manage this for the time beingwe've created a disk partitioning toolcalled pte which is capable ofmanaging the actual real gpt layout onthe disks and creatinggpd partitions that can then be usedwith the filter driver with os2 this isan interim measureit won't be necessary in the long termonce gpt support has been integratedinto the normal arc os partitioningtoolsbut when i do my install you will see meusing ptein case you're wondering what it whatthat is that i'm usingso pte can see the complete hard diskeven hard disks larger than twoterabytesalthough this is limited to non-scuzzyhard disks but on the other hand you'renot really likely to encounter gpt onscuzzy anyway soto get into a slightly more technicaldetail about how this workswhen you create a gpt partition for usewith arc osit gets assigned the or you assign itthe guidor universal partition type identifierwhich has been designated for arc osnow the filter driver that i mentionedrecognizes these partitions when arc osboots and it presents them to theoperating system as individual style mbrindividual mbr style hard disksthis translation is all done in memoryso the underlying physical hard disk isstill gpt formattedthe os2 operating system and das themanager however see themand think that they arembr disksnow these partitions these emulated gptmbr drivesget mounted automatically the ones whichare assigned the arc os guidyou assign them a drive letter and theywill that drive letter will be the sameacross all installationsnow other gpt partitions which are notmarked with the arc osguid such as you know windows linuxwhatever gpt partitions they can also bemountedby assigning them drive letterswhether the file system is supported andso on that's a separate question but youcan mount non-os2 gpt partitions byassigning them drive letters and in thiscase these drive letters are specific tothat arc os installationand furthermore partitions of any typecan be mounted or unmounted at any timeby simply assigning or removing theirdrive letters kind of like how lvmdoes thatand this assignment is persistentbetween rebootssousing gpt on arca osprovidesthe following benefitsyou can install arc osnext to windows on pre-loaded computerseven on the same gpt hard disksorry about that uhsomething just uh went slightly glitchythereso as i was saying there's no need toif you're using gpt and archive osthere's no need to wipe and reformat thepre-loaded windows hard disk on newcomputersyou can simply install arc osnext to that other operating systemassuming of course that you can resizeits partition to make the spaceavailablealsowith gpt disks there's no morefrustrating disk geometry errors in lvmso archos arc os will no longer complainabout certain disk and partitioningerror issues that you may encounter withmbr style hard disksandhere's a nice one you can use hard diskslarger than two terabytes with arca oslet me say that again you can use harddisks larger than two terabytesand be able to accessmore than two terabytesunder arc osnow when managing gpt disks you can alsouse other gpt partitioning tools or diskimaging tools from other operatingsystemsbecause they will simply see the arc osgpd partitions like any other gpdpartitions and for its part arc osdoesn't care about the gpt disk geometrybecause the filter driver handles it allnow the biggest current limitation isthat each gpt partition that's createdfor arc oshas a maximum size it has a maximumindividual size limit of two terabytessoin order to use disk space under os2including arc osyou have to assign it a drive letterthere are up to 24 drive lettersavailable for usea and b are reserved but you've got therest of the alphabetsoyou can do the math with a maximum sizeof 2 terabytes 2 times 24 volumes is 48terabytesso thatis the new effective upper limit of diskspace on arc os even with gpt supportwell i say new that was technically truebefore of course but with mbr discsthere wasn't really much chance ofgetting close to this limit anywayso48 terabyteswe hope that's enoughat least for nowanother limitation that i should mentionis that usb and other removable disksare not currently supported this waysoinstallingarc oswith uefiwe provide we will provide install asingleinstallationiso or usb stickfor both modes sothe iso the usb stick for installing arcosare they are and will remaindual boot supporting both uefi and biossystemsyou so you don't need a separate installdisk or stick to handle uefi systemsanotherpoint that i should mentionisonce you have finished the first phaseof install and put the operating systemyou put arc os ona uefisystem onto the hard diskbooting from the hard disk under uefirequires what's called an efi systempartitionif you already have an operating systemon your hard disk running in uefi modei one should already an efi partitionshould already existifthis partition already existsit will be used arc os will use itifit does not exist the arc os installerwill create one for youyou may stillhave toconsider things likeboot management from dual bootingmultiple operating systemsthis isthe various approaches for this arestill being consideredby developmentbutthis issomething that will bemadeclear and supportable by the time thisbecomesgenerally availableand going back to something i mentionedearlierinstalling with uefidoes not require the use of gptalthough it is recommended and you willneed gpt if you want to access anexistinggpt for gpt partitioned hard disksojust wanted to make some of those pointsclearnow that i've given you a briefintroductiontowhat uefi and gpt support are all aboutandwhat the status is with respect to arcosnext i'm going to be showing youan installation i'm going to bedemoing an install of arc os on a modernuefi system with a gpt hard diskso what i'll do now is pause the videoand then switch over to my demonstrationsoi will see you in just a momentall rightso now we're going to start thedemonstration of installing arca os on auefi system with a gpt hard diskso this is a fairly modern system withan 8 core amd cpuso it starts with us selecting the bootdevicefrom the uefi menu hereand we've got the arc os usb stickinsertedsowe're going to select thatas you may notice we've also gotgrubinstalled because this is a system whichalready has linux installedso here we're going to just select theboot device as the usb stickhere and that will take us to the usualarc osbootscreenand then we'll go into the boot optionsmenu now this looks much the same as itdoes with the regular already releasedversions of arc osthe main difference is well first of allyou can see the uefi stringat the bottom right of the screen so youknow that it's booted in uefi modeandyou can ignore theversion string at the bottom therethat's just because this was built outofdevelopment and we haven't changed theversion string for the preboot menu justyetso at this point it's basically just gothrough the preboot menu check thedevicesthere are a few things that we can'tchange in uefi mode and they're noted onthe screen so there'suh there's no real need to go through indetail what i'm selecting becausein most cases it's pretty much the sameas any other arc os install except thatwe also have thenvme driveras a storage optionyou'll see that on the storage page sojust these are the usual options herethere's the nvme hci and ide driversfor the hard drive controllers it's areal technic nothing fancy thereand this is all just default so we saveand now what we do is we select theresolution and it just starts upunpacking the boot files if you've everbooted an arc os usb stick beforei mean this should look familiarnothing especially new in this part ofthe processnow this is a fairly slow usb stickwhich is why this doesn'trun especially fast to unpack the filesso unfortunately i think the usb stickis actually a bit well quite a bit olderthan me than the system i'm installingon so if there's going to be abottleneck it's going to be reading theusb stickso we turned off the boot logo as youmight notice justfor development purposes and then thisis all the usual boot messages not muchto see here except the acpi driverand again this part of the process ismuch the same as as any existing versionof arc osit's just setting up the installerpreparing to start presentation managerwhich you'll see come up in a momentalright so now the installer is startingwhat we're going to do first is actuallygo into system managementbecause there's something we have to doand what is it we have to do wellbecause this is still a developmentbuild we don't have an integrateddisk manager we don't have gpt supportintegrated into the like lvmgraphical tools yetsowhat we've got at the moment is astandalonepartition editing tool that'sspecifically for managing the gptpartitions that's called pde so umwe're going to start it now now you canaccess it from the disk menu buti think we're just going to run it fromthe command prompt hereso that you can see what the program iscalled pteand that might be handypost install as wellso here you can see thedisk partitions as seen and we'll justturn on the guid now the gu idisthe unique identifier for uhwell for a gpg partition i mean gptstands for guid partition tableso eachpartition has the unique guidand also a specific type and for thetypethere are many kinds and vendors cankind of define their own sothere's been a an os2 or rather arc osgpt partition type defined nowso we will be creating one of thoseso at the moment you can see we've gotthe efi system partitionwe've got the previously installed linuxand linux swap partitionpartitions and then there's a chunk offree space at the end so we're going togo thereumwiden that out a bitso we're going to select the free spaceand create say a 4 gig partitionand assign it as an os2 type gpdpartition and give it drive csofour gigs well four thousand mags whichisn'tquite the same if you want to gettechnical and arc os uhgptso that shows up now we have to actuallysave changes for this to take effectand once we save it it'll actuallyrefresh and show up in the in the properorderso now that's done we can close out ofthis and restart the installerwhere we can sort of proceedas we usually wouldso we don't need to change anything herereallywe've already read this sowe can kind of speed speed read it hereif we want but let's just continuejust sort of the default installpersonality andnow we still do theum disk checking here justto check for various things as well asin case there might be non-gpt disks aswellbut you can see that unknown partitiondrive c that's the gpt partition that wejust createdwhich you can seeunder the target volume drop down thereand we'll be able todo something once thedisk checker finishes hereokayso if welook at the volumes and manage volumesbrings up mini lvmand you can see that every umwell it kind of presents gpt slots therebut it's got the whole list of drivesand partitionsincluding the gpt partition we createdi'm not going to reallynarrate what's going on here becauseit's allsort of the usual stuffmuch as i love newfoundlandthis is uh eastern canadahardware here you can see the nvmedriver is selected there this is thereal techniqueusual computer name work group nameuser let's give the computer a slightlybetter name herestill allow underscoresno it does not allow underscores andhost names okayi should know that by nownow we're ready to install and yeahthere's no point delaying just go onformats the disk quite quicklyand here the install has started so atthis point it justgoes on much as it usually wouldso[Music]notreally much else to say in this stage ofthe gameas i said we've got a fairly slow usbstick here which is why it's not goingterribly quicklyokay in fact what i think i'm going todo is just sort of pause it herewhile this goes andi'll resumein phase two because there's not anyparticular need to make everybodysit through the longprocess of phase one here i'll i thinki'll just quickly show you a bit ofphase two and then i'll skip ahead theretoobecause that one takes even longerso at any rate uh that's the the startof the install first phaseas you can see there's no rocket scienceinvolved we've just umwe're able to select a gpt disk we usethat special partitioning tool for nowbecause this is a development build thatwill be replaced with a more integratedmore familiar more usual partitionmanagementonce we get that donebut as you can see it's already veryfunctionalstill very easy to doand yeahso uh i will resume this in phase 2.we're back and beginning phase 2 of theinstallso we're booting off the hard disk nowandas you see we have grub installed andwe've actually already added the arc ospartition to grub here just to save sometimeandyou're notrequired to use grub specifically it'sjust this laptop had linux on it whichcame with grubin principle i think you should be ableto use just about anyor any number ofuefi capable boot managerswe're stilluhto arkanoacontemplating uh what boot manager inparticular or what boot managementsolutionwe're going to providewhen thisbecomes a retail product butfor now for the purposes of thisdemonstrationgrub will sufficeso let's select the arc os partitionwe get our boot blob and hereuh ifanybody has seenour uefi demos beforeuh this isa list of bootable partitions that'spresented by thearc os uefi loader andagain this is just kind of theconfiguration we have it in at themoment this is something that can beturned off andas i say we're still contemplatingexactly how we're going to present thisin the final productbut for now just understand that whatyou're seeing here is a list of bootablepartitions that the os2 or rather arc osuefi loader has detected and so you seeour drive c which is the four gigabyteuh partitionthat we created and formatted is jfs sothis is where arc os is being installedsojustselect that and continue and notice thatwe have a beautiful full color boot logonow another one of the benefits of uefiand look at that we're already donebootingthewonders of modern hardwaresoat this point phase two is running andis going to run for a whileso as before there's not really a lot ofpoint in me continuing to narrate thissonow that i've shown booting off the harddisk for the first time starting upphase twoi'll pause thisto let phase two finish and thenwe'll resumeonce the install is completeall right so the install is now doneand we're just booting up one last timeas beforebeautiful boot logofollowed by the usual driver messagesgoing by very fast because it's a fastsystemand we're done bootingand yeahi guess we have to check disk the usbsticknotice we've already actually finishedthe install heresojust a quick tour of the systemthis isfully functionalarc os system running on uefi hardwareand a gpt hard disknow dossessionthis is particularly significant becausea lot of work's actually gone into thecompatibility of dos sessionsin the last demonstrationwe showed this i believe the windowedsessionsbut full screenif i recall correctlyhad not yet been perfected and here weseedos full screen is in fact working wellthere's the old msd utilityjust to show a full screen app runningand winos2 alsofull screen sessionsworking very well now umi mean windows 2 is windows 2 we allknow what it looks likeumbut yeahthe um many of you have probably foundat least if you've tried uh that on alot of the hardware that's come out inthe last five to ten yearsdos and winos2 compatibility has tendedto suffer a bita bitsometimes full screen or windowed modesdon't quite work the way they should ifat allsowindows 2 full screen as demonstratedthat works but also windows 2 seamlessmodeis also working now and that'sanotherimpressive result of the developmentthat's gone into thisnowthesystemthe uefi systemthat we havehas in many ways allowed us to put in alot offixes and supportthat os2 dawson windows support requirein terms of the video hardwareas i said a lot of recenthardware onsort of classic os 2environmentsthe dawson window support is not thatgreat and the main reason for that isthe vga hardware the vga bios interfacesinrecent systems has just not beenvery well compatible with what os2expectsso uefithat vga sort of bios interface hasessentially been replaced completelywhich has been quite a lot of work toimplement but the great advantage ofthatis thatit allows much betterdirect controlby us overcompatibility because in a sense we arenow providing the vgabios ourselves or a certain subset of itthat's neededfor the os2 dos supporti guess you could almost call it a kindof software vga cardso the compatibility isreally um we should see much muchi'm not going to sayall problems are immediately andcurrently forever solved but i think theproblemsare getting fewercompared to what trying to run dawsonwindows applicationson a traditional os2 systemhas been in recent years andwe canor we are much better positionedarkanoa istoto improve that and fix problems as theycome up rather than being kind of at themercy of apossiblyslightly suspect vga biosso at this point umwhati would like to do is demonstrate somesoftware that's actually running on thissofirst of all that has to be installed sowhat i'm going to do again is pause therecording here and then resume once ihave somenice applications to show offso please stand by andwe'll be back in just a momentall right so first application i'm goingto show youis an old office application that runsin windows windows 2. some of you mightrecognize itso no greatdemonstration for this one i think weall know what this program is and whatit doesbut just demonstrating that it worksperfectly wellas it shouldsosort of demonstrating the capabilitiesof the the wino s2 system under uefiso we're going to do the same now forsome dos applicationsi found someold classic dos programsgamesand othersthat some of you might recognizeso let's take a look at the first onehereoh yes does that take anyone back king'squest the old sierra games those weregreatthere's not really much to say aboutthis one if you know this game you knowhow how cool they were butas i say it runs works very well andlet's go into some other applicationsnowokay uh let's go see them through someothers now umlet's see oh yesanyone remember this gameso yeah in spite of the uh the gimmickwhich some people lovesome people don'ti think it's actually just a really goodchess game tooso we canyou can see that runs uh very wellendos full screenlet'slet's get out of this and take anotherlook atsomething else shall weokay notice that these are running invga mode the king's quest demo isrunning in ega so we've got the abilityto handleboth of those resolutionsand some othersnever really played this game but it wasit was quite big once upon a timesolemmingsi'm not sure what it really is to sayherelike i said i've never really playedthis game soit's uhinteresting at any ratei think that's enough for that thoughnow there's one more thing i want toshowtwo things actuallyanother another classic game this one ispretty famous always pretty famous inits daysimcity 2000i can't say i ever really got into thisgame uhi was more of a civilization personmyselfbut i know how popular it wasso again we've got a good showcase ofjust uh the graphics compatibilityof dos under uefias you can seethere's nono issues hereall works perfectly well which i thinkis a testament to the great job that thedeveloper has done on the vga support onthis it's really quite impressivei think that's about enough for gamesthere's one other program though thatmightmight be interestingand that's another office applicationand i think you can see what it isso word perfect 6.2 for dasi think a lot of peopleuse this maybe still use itso if you do that's certainlysomething to put your mind at ease thisisthe compatibility being demonstratedso we have a good rangeofcompatibility uh dos applications and ithink in many ways we're doing betterthan we were under the traditionalbios system on recent hardwaresothat's uh that's our demonstrationso i hope you found it interesting andenlightening andthank you very muchhello everybody yes sorry i'm a bitconfused due to the lack in the stream istill hear alex talking here but it's a30 second delay so if you can hear himon my headset alex is still echoingum a couple of questions where i'mcollecting here the questions fromdifferent sources two irc channels andyoutube video streamum and oh sorry let me uhsorryyeah yeah i'm movingthere sorry now i saw myself in thevideo stream anyway that's an echo echowhatever there are a couple of questionsthat popped up in theum in thein the presentationsome of themi can answer i'm also part of thearcanova test team so we've beenwe there has been a lot of testing thathas been done on all of this stuffum there's a question fromcurtis jones whetherumuh whether sound is supporteduh that's actually a long-standing wishthat i also had in my menses days umand lewis rosenthal in his upcomingpresentation willum willgo into further detailin that project that's called the datatransport agent i've actually seen thispresentation already so i can tell youthat that question will be answeredbut in 510 there is currently nosound support for dos and windows 2sessionsthere was also a question i see hereabout hpfs file systemsumi don't knowwhy you would be dependent on hpfsumit seems thatthere are of a small amount ofapplications that will only work on hpfsbut that primarily seem to beeither dos applicationsthat use some weirdand not daily form of querying the filesystemor you need to create a smallerpartition let's say less than twogigabytes or on that boundary and if youhave a application that still doesn'twork onum on jfs then you know the standardstatement that arc noah always gives intheir presentationsand i'll repeat it on their behalfno ticket no issue soit should it shouldso applications on it on jfsshould workumlet's see hereare there any other and i was looking ohyeah i see here that secret fasten rodis asking what about the two gigabytebarrier for dos and windows 2. does dosc 2 terabyte disksii'm not certain i don't know if somebodycould answer that buti actually think that you'reconfusing two things herebecause the two gigabyte barrier is foruh the file size and the two terabyte isfor the partition size soas far as i can tell you will be able tosee the fullsize of the you will be able to see thetwo terabyte partition under dos butumyou will not beuhyou will not be able toaccess the files bigger than twogigabytes now if anybodyhas a correction on that statement fromarc noah just let me know on theirc channel buti think that has always been the case onos2umlet's see herei need to scroll back here in theyoutube chatumlet's see herethere was a question fromschreiber stein i wonder did youimplement a jfs ui file file systemdriver or does the loader do everythingumi think that question would need to beaddressed to arc nova theni did look intouv advice support and my day'sadventures when i still used to workthereandbest i can guess it should have somesupport built in to read the file systemdriver butlet's see herei'm just following the chat here what'sbeing said those can only see up to twogigabytes of free space do anythinglargeruh will be reported incorrectly but itcan accessthe storage okay that's an answer thatalex taylor just wrotesoum let's see hereso about the jfs file system in theloader i'm notcertain in uefi loaderi think this is pretty impressiveconsidering that os2 is 30 years old andwe're now seeing it boot on the systemwith everything bolted on top of it usb3 nvme gptrunning with acpi with a whole bunch ofcourseyeah impressiveum are there any other questions i justthrow that out on the youtube channelnow i just need to wait because there isa lag of about 20 to 30 seconds beforeuhmy question arrives with youumi do see here some people on the youtubechannel that find it uh great to seethat some of thethose applications that they werefamiliar with and are familiar withare working yeah and i think also thevideouh support for the games is prettyimpressive considering that effectivelyit's a software vga adapterumare there any questions here i think i'mjusti'm seeing nobodyuh raise a question hereas the saying goes are there any morequestionsgoing once going twice well you canalways ask them on the irc channel andafter the presentation from lewisrosenthalwe can alwaysgo backtoany questions regarding the uefipresentation since two presentations aresomewhatrelated to each otherokay then we'll now go tolewis rosenthalrosenthal from arkanoa llcwith his presentation on the arc osroadmapthis is also pre-recorded but lewis isavailableafter the presentationor also during the presentationto answer your questions and after thispresentation i will alsobring all the questions together fromirc and the youtubechatcan you please starthithis is your arca os update for 2021covering the 510 release of arca osi'm lewis rosenthal managing member ofarkanoidmost of you probably know who i amalready so i'll spare you the biothe five one beta cycle is in full swingwe knew this would take some time to getto gaand we're pretty much on schedule withour own internal projectionsi know i know it can't ever get herefast enoughlet's just get some basic terminologyout of the way before we delve into themain points for the upcoming 5-1 releasewe talk about updates and upgradesit's important to know which is whichfrom our perspective so that you maybetter understand what you're doing whenyou boot from the latest installationmedia[Music]version releases of our software asmajor.miner.bug fix or maintenanceour current major release is five don'texpect this to change anytime soonour current minor release is 0 or 0and we will be upgrading to 1 with arelease of 5.1which will be our first significantpoint release since 5.0minor releases are consideredsignificant because they include newfeatures and for functionalityour current bug fix release for 5.0 issixand this is planned to be the last 5.0releasewe may still produce updates for 5.0while 5.1 is currentbug fix releases have to date included afew new features but their focus hasbeen and for 5.1 will also beon fixing installer bugs and otherthings which are more easily done withnew iso builds than individuallydownloadable packageswe'll talk more about updating asopposed to upgrading a little later onjust bear these points in mindas mentioned 5-1 will be the firstsignificant point release for arca oswe anticipate ga sometime late in thethird quarter or early fourth quarter ofthis year assuming we don't run into anyunexpected difficulties5-1 will go through our normalmaintenance release cycle510-511-512 etcwe don't yet know how many of thosethere may bethe 5-1 cycle completes we'll move to5.2 and so onwe have no specific plans for what 5.2will containor anysubsequent release at this timewe have lots of ideas and long wishlists of things we'd like to see in thefuture and reallythere's no stopping this train as longas we maintain our momentumas always these are forward-lookingstatements and should not be taken as acommitment to release any of thesehoweverthese are in our internal roadmap and wewill do our utmost to get them into the5-1 releasethat means that some of these may notnecessarily be in the 5-1-0 release butmay make it into subsequent 5-1maintenance releasesthat being said much of 5-1 is alreadyin beta at this point so this is notjust wishful thinkingthere are five key features in the fiveone data we'll talk about each of thesein more detail a little later onfirst and foremostis uefi supportthis allows arca os to be installed onthe latest generation of systemsgpt support is another feature currentlyin betagpt support is available for single andmulti-volume installation typesand we can obviously thenboot from media partitioned with thisschemeno more mbr requirementsno more cylinder versus megabytealignment issuesnvme support will be available in theinstaller so these systems will be ableto boot and utilize nvme devicesfrom the get-gowe will have our first national languageversions of arc os generally availablei'll talk about those a little later inthe session but several are almost torelease quality thanks to our hardworking translation teamfive one will include an upgradefacility to go from arc os 5.0 to 5.1 inmuch the same way as the 5.0 updatefacility moves between 5.0 releasesas with updating the goal of the upgradeprocess is to take the system in itscurrent state 501 504 506and just move the os to the latestversion preserving as much of thepost-install user customization aspossibleall these features are in beta right nowlet's discuss uefi for a momentfor those who may still be unfamiliarwith the term we're all os2 users hererightyou may hear the acronyms efi and uefiused almost interchangeablythe only difference is really that uefiis the unified extensible firmwareinterface which is the latest efispecificationintel developed efi and by 2005 whenother companies got into the technologyuefi incorporated later submittedchanges and deprecated efi 1.10the current uefi spec is 2.9with 2.8a being the latest publishedversionarca os can boot in this environmentjust like other os's using the efisystem partitionarca os may be added to any third-partyboot manager we plan to include a miniboot manager for thisair boot is not uefi aware and cannot beused in this environmentarc os itself is relatively unchanged inessence the arcanoa compatibility systemancs as we call itprovides an expected environment for os2this means that it essentially providesin software what was previously providedby the hardware using a traditional biosthe key takeaway however is that we nowcontrol that emulated environment sounlike different hardware from differentvendors behaving differentlymost uefi systems should behavesimilarlydos sessions should work for all systemsagain and not just on some machines butnotothers the five one installer willcreate an esp that's the efi systempartitionif one is not already present and usableand will update itif the esp already contains arc os uefiboot filesthe importance of uefi support for thelong term survival of the platformcannot be overstatedeventually we will run out of usable 15to 20 year old hardwareand either a reliable traditional biosor a relatively complete compatibilitysupport module or csmmany of the newest systems no longereven provide a csmancs the arkanoid compatibility system imentioned beforemakes possibleto boot without even a csm from thehardware manufacturerlet's talk about gpta few months ago we announced our blogthe grid we selected for the arca ostype 1 partitionthese are the partitions which will beuh used in arc os 510grid partitions are all the sameother than having different quiz todifferentiate their purpose and or filesystem formatthere are no primary or extendedpartitions with logical volumes they'rejust partitionsand you may have almost as many of themas will fit on a devicei'm not aware of a hard limit butobviously for arc os we need a letterfor each volume in order to access itso we do run out ofletters in the alphabet at some pointmost new off-the-shelf pre-installedsystems today come with a disk likely inssd but not necessarilyconfigured using gptour gpt solution will be rolled out inphases with each phase plan to bebackward compatible so existingconfigurations may be preservedv1 which will be introduced with arca os51 will provide support for arca os type1 partitionsof up to 2 terabytes in sizecreated on mediain excess of two terabytes that meanssmaller than two terabytes as well aslarger than two terabytesthe installer will allow creation andformatting of these volumes and arca oswill happily boot from them just likefrom mbr style partitionsnvme the successor to ahci has becomethe current standard desktop interfacefor storage devicesnvme was specifically designed to takeadvantage of ssd technologythe nvme driver version 1.01 wasreleased in april and is included in thecurrent arca os 51 betathe installer fully supports nvmedevices just like any other storageadapterthis is another key technology to allowarca os to install on modern hardwarecurrentlygerman dutch spanish french italianrussian simplified chinese traditionalchinesejapanese and korean are all at varyingstages of completion with the ones mostlikely to be in the 510gabeing german dutch spanish frenchitalian and russianthe double byte character set languagesare somewhat behind the others in termsof readiness but we are hoping for somemore input on the chinese variants atleastit is likely that when 510 is releasedsome nlvs will be missing translatedparts here or there perhaps somedocumentation perhaps on applicationsexpect these to improve over timeeven ibm didn't get everythingtranslatedwe can add more languages based uponmarket demand so if you have need orbetterknow of a prospective enterprise with aneed for a number of licenses for agiven language please let us knowa commercial contract could fund aconsiderable amount of work and everyoneneeding that particular language wouldbenefitso what's the difference between updateand upgradewellthey both work similarly and the endresult should be about the same whateverarc os version you had beforeends up at the same level as theinstallation mediathe difference is really behind thescenes and how much moving about andreplacement is requiredas we'll discuss later an upgradelicense involves a new purchase whereasan update is included with a support andmaintenance subscriptionupgrading to five one is only possibleto five one english because english wasthe only 5.0 nlvand upgrading will not change the nlvwhen 511 becomes available that willinclude support for updating 510 andagainthe installed nlv must match theinstallation media nlv in order toqualifyto change nlvs a fresh install will beneededoh and all 51x english releases willsupport upgrading from any50x english release[Music]among other features planned for the 51release cycle in generalwe havea new printer manager to replace theindividual apps we have now and providea simpler printer installation processa new desktop background page and aproperties notebook with some fixes forsome known problems and some newfeatures like timed wallpaper changespreviews of more types of images locatedin multiple directories and so forththe new hardware manager hardwareexplorer which provides more detailedand updated information on the installedhardwarewe'd like to include true desktop searchto effectively locate text and pdfs andother data filesrecall looks like a good choice for thisand we are looking at updating to themost recent release including the qt5gui for itwe really need a newer java than java 6.java 8 is no longer even a useful goalwhen the latest open jdkis 16 and 17 is in developmentwe need a developer to take on thisimportant project howeverwe want to add the ability to selectautomatically with the ability for theuser to override that decisionthe cpu platform for the unixcompatibility systemwe already ship on the arc os 506 mediaboth i 686 and pentium 4rpms this would set up the system aspentium four if the hardware isappropriatewe may add some new desktop productivityapps to the iso or we may simply makethese available for download andinstallation from ampm or thesubscription downloads on the websiteit's time for a more capable vnc viewerand server so look for these in a 5.1releasewe're looking at ways to modernize someof the default inec config settings fora better network and broadbandexperience right from installbecause security is one of our focuspoints here at arcanoawe'd like to make a system-wide chainedsquid proxy and privoxy setup aselectable software item and add aconfiguration guithat configuration gui is not yetwritten or even planned out yetbut we'd like to add thatmulti-mac wireless drivers are currentlyin developmentthese will also be available separatelybetween iso releaseswe plan to include qt5 and the new qt5based otter browser when it is ready andstable for production useas an optional software selection inaddition toupdated builds of the mozillaapplicationswe have a totally new archimapper inbeta which is written with a qt4 guithis is scheduled to be in the 510releasewe think you'll like it a lotdt audio currently allows windows 2audio to be routed to uni-oddwe haven't released this with any arc osversion as yetwe want to couple thatwith a virtual sound blaster driver forfor dos sessions to route dos audio touni on as wellall of this is in preparation for afuture 5 1 release aimed specifically atretro gaming and showing off our robustdawson win3 support for classic pc gameswhich are not playable natively on anyother modern platformto do this we also want to provide solidjoystick support which promises to bechallengingparticularly to support analog joysticksthrough game port to usb adapterslet's revisit the update versus upgradequestionas i've said updates are included in anactive arc os support and maintenancesubscriptionan update moves between bug fix releasesfor the same major and minor versionso 505 to 506 is an update502-5056 is an updateto 506 is an updateand as long as the subscription is inforce the latest5.0.whatever iso may be downloaded andused to perform an updatean upgradeinvolves a new license purchasewhile we have not yet set pricing forarchivearc os 51 upgrades from 5-0expect a sizeable discount overpurchasing a new license freshan upgrade install will take whatever5-0 release is currently on the systemand upgrade that to the latest 5-1 asprovided on the iso like a new editionof a book5-0 support and maintenance is not goingawayinstead we are planning to maintainthose 5-0 subscriptions for customerswho do not immediately upgrade to 5-1and make available updates which areappropriate for 5-0 as part of thatsubscriptionby appropriate i mean updates forcontent in arc os 5-0 this wouldspecificallyexclude any content only introduced andprovided as part of arc os five onefive one licenses will have their ownsupport and maintenance subscriptionwith content appropriate for five oneuefi updates for examplenow there are probablya ton of moving parts which i've leftout of this road map installmentso feel free to ask questions aboutspecific items and i'll do my best toanswerhellowell that was lucy's presentation on theroadmap where arc os is goingi think based on alex's presentation andthe roadmap that we have is that wehave a lot ofnew items to look forward on os2and for the people that have always beensaying that it's dead welluntil it's dead then it's deadi've asked on the youtube channel andtheuh irc channel if there are anyquestions for lewis lewis will answerthem via irc or on the youtube channelumanduh i can read them back here for thepeople who are not on the irc oryoutube chat channel i'mi'm spinning my head round and round tosee if anybodyum has any questionsbut so farit's pretty silenti guess that is a good sign because thenit means that theuh oh yeahis there any pathway available for thoseof us moving from an mbr50x installation to a uefi 5.1installationeither conventional through a n orotherwise that's whatuh ehabarian is askingumsoi'll let lewis answer that questionwhat lewis is answering is that willrequire a backup wipe repartitioninstall and restore operationyesi can testimon testify to that becausethe problem isthere aretrickery tricky ways to convert from mbrto gpg butthat can be a slippery slope and a lossa potential loss of data so oh sorry loulouis says that you can keep mbr withuefi no problemif you want to move the gpt then theconversion is manual that's what lewisis askingalthough in my experience windows 10 forexample will flat out refuse to boot inuefi modeunless the disk is not gpt so maybethat's possible for an arc os system butthe uefibasically from what i understand thatuefi standard allows booting with an mbrdisk but for example windows 10 and somelinux distributionsand force you to use gpt but that'sthat's a uh that's something that as acommunity we'll just have to find out iguess it's already a great step forwardthat we now have this technology comingtowards uslet's see here you lewis says that ouruefi does not require gptsoum i'm just looking here on the youtubechannel if there are any questions therebut i think also as alex said you knowif you already have a runninginstallation then aswitch over toumto uefi and gpt is not a requirementarc os will continue to supportlegacy boot or the system with the biosas it's working right now so[Music]um martin from os2 world martin eterbeedis asking on irc if the dta is producingsound under a dos vdmhe said that i tried an older beta twoyears ago and i don't knowuh if there was any more progress on itso i'm just waiting for lewis to respondto that questionlewis answers no dta audio is awindows driverand we need a vdd fordos sessionsactually the dta originated fromthe work that i did with john gowancirca 2004and that indeed is a driver that youinstall in windows 2 and then via aset of layers it talks directly to theaudio driver butthere was some sound blaster codedeveloped by another developerbut that never came to fruition soumibrahim is askinggotcha another question am iam i correct to assume we won't be ableto get new features announced so farwithout a full reformat reinstalled toan mbr or otherwise uefi systemalex is responding to that to ibrahimquestions on irc and his answer isonly for uefi specific featureslike the dos softwarebaseddos video supportand we've almost hit the 80viewers on the channel so i guess otherpeople looking at this who don't knowos2 find thatjoke but for us that'sthat's pretty impressiveand i'd just like to remind people thatas one of thepeople in the os2 community always saysstephen levine always two users live incaves and they sometimes come out hencethe domain name warpcave.comumthat was just a short messagebut i'm seeing here that there are nofurther questions here soabraham says and just to clarify forsake of it you cannot install the uefispecific features if you are migratingfrom a csm system even if the target isa uefi platformwell to give you an idea what i've seenwith testing basically the installerworks in two modeswhen your system starts up and you havelegacy bios boot and uefi boot enabledthe usb stick for example will show uptwiceonce for the bios boot and the other onefor the um for the um legacy boot sorrythe uefi boot and it's depending on thechoice that you make thereif the ueficomponents are installed in other wordsif you install legacy boot then theinstaller will follow code path andinstall just like arc os 506 is nowinstalling if you select uefi then acouple of other system files arereplaced due to the way how uefi workshow it worksuh lewis is sayingin theory you can upgrade csm to uefii don't know if lewis is still going tomake a follow-up statement about thatah i see here on the youtube channel isee here thatthe userschreiberstein is asking will there bemidi mt-32 emulator for those sessionsor will it be pcm onlythat i can answer with certainty fromwhat i've heard there is only going tobesound blaster 16 andumopl3 emulation for those gamesi don't think they're planning on doingmt uh 32 supportlet's see heremigrating alex is furtheranswering the questions from ibrahim hesays migrating to a uefi only systeminherently means getting the uefifeaturesit wouldn't workotherwiseexactly they can't be installed a lacarte lewis is answeringsothe basic thing is is that you selectuefi then you install the uefi featuresandusing a csm boot you get the csmfeatures just like in 506 it's dependenton what you select for the bootokay ibrahim now needs a cup of teaandor coffee i think he writes on the irc[Music]i think i see no more questions comingup here i'm justi'm sorry i'm looking here at threedifferent chat windows one two ircchannels in the youtube chat so sorryfor looking a bit confused butumyes i don't think there are anyuhfurther questionsumuh avail that are no further questionsuh i'd like to then suggest that we takea breakuh here in the netherlands it's 5 30 sowe are going to serve dinner and peopleon the east coast are in the of theunited states are now just about readyforan early lunchand people in california probably nowwant to start on their breakfastand i guess our viewers in australia aregoing to be the real die-hards orthey're falling asleep alreadywe did try topick a schedule that for life questionsthat everybody can look in but we can'taccommodate all 24 time zones okaybon appetit enjoy your meal lunch dinnerwhateverwe're shutting down for now we'll beback at umat7 pm dutch timeor1 p.m new york timeokay um i will see you later and i'll bekeep reading the the irc chat and etcand we'll makeuh and we'll makenotes for it later and then we canalways revisit some of those questionslatersee you in one and a half hours thankyou for your time and attentionohtime flies and having funum as you might have noticed i was justlooking ata new browser let's see when i startedit 1818 okaythat's what you see running on thescreen in the background is the newauto browser which will do ademonstration lateras some people have already noticedfirefox is starting to show its age butwe'll come up with a demonstration laterof the new browser they'll also go intopublic beta soas you can see i can see myself nowrunning in in stereo but just with adelay of about 30 seconds so i've nowgot a mime actor actually imitating mebut just with 30 seconds late okay um wecan go to the next presentation pleasecould you please uh start thepresentation from alex um oh by the waywe've had a slight reshuffle of theprogramuh but i don't think that's really anissue for nowum[Music]next up is alex taylor with apresentation on arkham mappershort summaryremember how you made connections underos2 to a network share on another pc orserverthat's what's called a lan manager andthat has beenquite outdated by nowarca os already ships with somethingcalled arkham mapperbut that also doesn't meet therequirementsfor modern usage and alex has beenworking on a new replacement for thatthis is also a pre-recorded presentationwe willpatch in alex via skype after thispresentationto answer any questions andi've already seen it of course but ithink you'll be impressed by how itlooks and how it worksalex the floor is digital to yours startthe video pleasehelloi'm going to talk about the nextgeneration of lan client or archimapperwhich is set for inclusion in arc os 5.1nowlan clients have been available for os2since the very early daysand they've been a standard part of theoperating system since warp connectthe last iteration of ibm's os2 lanclient the file and print clientwas last updated in the conveniencepackages which are now around 20 yearsoldunfortunately the file and print clientjust doesn't really support modern lanenvironments anymorenow for compatibility arc os stillincludes the file and print client as anoptional componentbut for modern networks containing sambaor windows systemsor which use active directory orkerberosit's really necessary to use a sambabased land clientsowhat is arca mapperarchimapper is basically the umbrellanamethat we give tothe net drive based land client which isincluded in arc osso to be specific archimappro includesthe following componentsthe free edition of net drivewhen i say free it is licensed forunlimited usewith the netdrive samba plugin and thatplugin onlyand without the standard netdrivecontrol panelsoarca mapper includes thatnet drive and it includes that pluginndp smb the netdrive samba pluginadditionally it includesa set of utilities known as the sambaclient utilitiesas well as a kerberos 5authentication system calledheimdalland finally andperhaps most relevantly here it includesa custom user interfacenow in arc os 5.0the interface that was provided for arcamapperwas a rebranded andslightly tweaked evfs guiwhich is afairlystraightforwardgui that was writtenprobably about a dozen years agooriginally it's evolved a bit since thenit's actually evolved quite a lot sincethenum primarily written by myself andherrevich bauernfeinbutwe decided or iand in conjunction with the others atarkanoadecided that it istime to providea differentnew generation of user interfacefor the upcoming arc os 5.1 and i'll getinto why in a little bitso the new archimapper ui is set forinclusion in arc os 5.1 and that's whati'm going to be introducing to you allhere todayso then why a new archimapper uiwell as i said arcos 5.0 used arebranded evfs guiwhich was you know it did the job butthere are some issues with thisthe mainthe main issue i would say is thatevfs guiis kind of tricky to maintain it'swritten in a fairly specialized uhrex basedguienvironmentandit'sthe program has grown to the point andto a level of complexity where it iskind ofapproaching its design limitationsum it was originally designed as a veryvery basic simple programand it's kind of had a lot offunctionalitysort of layered onto it over a number ofyearsand with each new bit of functionalitythe whole program kind of gets biggerand a bit more cumbersome and tricky tomaintain and there's a lot of movingparts that areyou got to make sure fit togetherproperly so it's becomingon an architectural levelrather tricky to keep maintaining andexpanding this programso that's one reason why i thought itbest to move away from it going forwardanother limitation is that evfs guirelies on the samba command lineprograms for a number of pieces of itsfunctionalitybut doing this can and has causedissuesin case the syntax or behavior of thesecommand line programs changes in theslightest waysowe've opted to go for a new arca mapperui for arc os 5.1and this provides us with a number ofadvantagesthe new versioninstead of calling standalone commandline programs it linkswell it does this in one or two casesbutgenerally speaking it links directly tolibraries either the samba libraries orthe kerberos the heimdall kerberoslibrariesdoing this is faster and more reliablethan calling separate programssecondit uses a modular design it which isconsiderably more flexible uh both on atechnical level uh as well as in a legalor licensingcontextso i'll show you what i mean by amodular design in a little bitand third itin my opinion it provides a moreintegrated slightly more os2 like uhuser experience at leastwell i say os2 like more in the sense ofthe oldlantools that osu users are perhaps a bitmore accustomed to usingat least historically speakingso let's get into how this has beenimplemented and what it looks likeso as i sayit uses a modular designand by this i meanthe functionality has been divided intospecificcomponents and each of these is providedas a separate tool but they can worktogethersothe modules or components that make uparchimapper ui the new versionarean authentication or a logon componenta connection management componentwhich handlesmappingactually mounting drives to your systema browsing component which allows you tobrowse the servers and shares availableon the networkas far as your network supports that ofcourseand finally command line utilitiesand so this basically means somethinganalogous to the good old net commandso with all this uh there are a numberof requirements they're not particularlydifficultit doesrequire the latest caleb c and gccruntimes because i've been building thiswith gcc 9.2it also requires the latest qt4 runtimebecause the graphical components arewritten in qt4and i believe that is 4.7.3 is thelatest versionand finally it requires the heimdall andsamba client packagesthese are available from netlabs you candownload them or useyum oran pm to install them as you preferbut of course all of these will bebundled into arc os 5.1 along witharca mapperso let's take a look at the first pieceauthenticationthis is a tool that is referred to asthe credentialmanager so the normal user workflow in atraditional lan environmentis to log on once before accessing anylan resourcesand i say once because this this is aone-time logon normally speakingonce you have logged on you can thenaccess any resourcethat is valid for that logon id forthose credentialswithout having to log on again each timeyou want toto mount or access another resource aslong as they use that same credentialso in multi-user operating systems likelinux or unix or windowsthis process is generally integratedwith logging onto the system itselfeither by actually sharing credentialsbetween the local system and the domainor alternatively by using the systemcredentialsto decrypt and access stored networkcredentials automaticallywherever there's a little bit of aproblem here because os2 is not amulti-user operating system you don'tnormally log on to os2when you boot it up sothis processhas to be handledseparatelynow archimapper is based on the netdrivesamba pluginthis plugin authenticates each resourceat the time you mount itos 2 normally has no standard way toremember credentialsafter you've entered themit doesn't have any centralizedcredential key store for exampleand without something like thisthe user id and passwordwould have to be entered again by theuser every time they wanted to mount aresourceso the concept behind the credentialmanager is to eliminate that problemwhile preserving security as much aspossibleso the credential manager supportsseveral tasksfirst it provides a replacement logondialog whichin addition to providing the typicaluser password and domain inputs alsoallows the authentication type to beselected which would be ntlm nt lanmanager or kerberosand then it acts accordinglyfor kerberos authentication it requestsa kerberos ticket granting ticket askerberos calls it from the domain'sauthentication serverso this is basically a graphical versionof the kerberos knit commandfor ntlm authentication what it does isit saves the entered user password anddomain into a special location in sharedmemory from whence the connectionmanager and the network browser whichare other modules that i'll be talkingabout on the following slides canretrieve themanother thing the credential managerdoes is to provide a view of currentlyactive credentialsand from this viewthese active credentials can bedestroyed which is to say purged frommemoryor in the case of kerberos credentialspossibly renewed if their active periodhas expiredand if you're not entirely familiar withkerberos what it is or what it doesdon't sweat it too muchyou probably don't need to know if youdon't know but it is essentially anauthenticationmethod that isan alternative to the standard sort ofntmicrosofttype of authentication although in factmicrosoft active directory does usekerberos in itscurrent iterations but anywayif you don't know what kerberos is youalmost certainly don't need itthe next component is the connectionmanagerthis is where you mount sharesthe connection manager is used toconnect to lan drives by mounting themthat is to say attaching them to a localpathso that you can access them like anyother driver directoryyou can think of the connection manageras being something like a graphicalversion of the net use command if yourememberthe ibm file and print clientso the basic connection dialog isdeliberately simple there's a screenshothere and i'll be showing you in a bitmore detail laterbut it provides fields for the sharename and the mount point and it has adrop down list for selecting from amongcurrently active credentials to use forthis connection and this also providesthe option to log on with a new set ofcredentials if you want tonowyou can mount the remote share to theroot directory of the selected drivein which case it behaves like the oldnet use commandhoweveryou can also mount it alternatively to asubdirectory by typing the full pathname into the mount point fieldthis means that you don't have to use upa drive letter for every shared resourcethat you mount and this is useful if youhave a lot of shares and not too manydrive letters to sparenow for each connection you can alsospecify the options which will be passedto the ndp smb pluginthe plugin offers a few of these optionslike ntlm levelsmb encryption support extendedattribute support cache settings andwhether or not to make the connectionread onlyand finally there is also an optionunderoptions which lets you automaticallysave the connection and i'll discuss howsave connections work in just a minutenow like the connection like thecredential manager the connectionmanager also has a management modein this casewhat it does is it lets you see all ofyour currently active connectionsfrom this interface you can disconnector save a connection and again i'll getto saving in a momentas well as create a new connection byeither opening the connection dialog orif you have one importing a netdrivendc fileand you can saveactive connections from the netdrivecontrol panel if you use netdrivein the form of ndc files and i believeevfs gui also allows you to saveconnection profiles in ndc format so ifyou have these files you can import themto immediatelymount that connection that's defined initso this screen also has a tabwhere you can view your restorable savedconnectionsokay so what are saved connectionswellyou can save a connection from theactive connection screen or as imentioned previously when you firstcreate a connection from the connectiondialog it gives you the option of savingit at that timeso when you choose to save a connectionyou have the option of either saving itas a so-called restorable or automaticconnectionor you can just export it to an ndc fileso restorable connections are actuallyalso saved as ndc files however they'rejust saved in a special directory whichthe connection manager scans on startupand these connectionsthese ndc files that are found in thisdirectory are shown on the savedconnections tabso from the save connections tab you canview deleteor restore any saved connectionyou can alsochoose to automaticallymount all restorable connections byrunning the connection manager programwith the forward slash restore parameterand i'll show you that when i do thedemonstration a little bit laterokay so the network browserbrowsing the lanthis has always been a bit hit and missin any environmentexample not all servers advertise theirpresence on the networkalso some networks may be configuredspecifically to prevent browsinghowever it is still an importantfunction that a lot of users expect andtherefore archimapper provides onethe network browser is pretty simple inconcept it shows a list of workgroupsand servers that can be seen on thenetwork and when selecteda list of shares on the currentlyselected serverbecause as i mentioned not all serversadvertise their presence on the networkyou can also explicitly add servers tothe network view by putting their hostnames into a special text file called nbhosts in your system etc directorywhether or how much of the list ofshares on each server is visible dependson the credentials that are being usedby the network browser for browsingnow by default it uses the sort ofstandard or semi-standard guestcredentials username guesthowever you can switch to a differentset of credentials if you need toof course if every server on yournetwork happens to require a differentlogin id for access then this can betricky to work with but i mean that'sjusthow it goesso uh the other thing about the networkbrowser is that you can you can mount aselected share by double clicking on iton the right hand uh paneland if you do this the connection dialogwill open with that sharename pre-populated and then you can justselect the credential you need hit okayand it'll select the drive letter orpath hit okay and it'll uh it'll mountit for youand the last piece is the command lineprogram this is the only part thatdoesn't require qt andjust run straight from the command linesoit's basicallymeant to be syntax compatible with theibm net command or rather a certainsubset of itso the arc mapper net commandprovides the following sub-commands netviewfor viewing the network net use formounting resources andnet help for basically giving you briefhelp on the previous two commands it'sfairly rudimentary at the moment but itis provided because some people dohappen to be comfortable or morecomfortable perhapswith the command line net commands and ii did provide it does provide a fewadditional options over and above theibm version for for example you canspecify whether to use uh kerberosauthentication or smb encryption and soon butgenerally speaking it's syntax backwardscompatible with the file and printclient net command at least with respectto those particular sub commands viewuse and helpall right soat this point i'm going to provide abrief demonstration of these programsjust to show you what the newarchimapper ui looks like in actionso bear with me a moment and i'll seeyou in the demoall rightsohere is a freshly installed arc oswith the new arca mapper uion itso it creates a folderor you will have a folder after installthat looks something likethis so these different icons representthe various different actions that areavailable uh using the new uinow the first thing i'm going to do isshow you the network browser just so youcan get asort of brief overview of what thenetwork here looks likeso this is the network browser it's verysimpleas you can see i've got two work groupsherethis one is beingmanaged by an ubuntu vm that i haverunning on my network on esxiand then this one is the one that mostof my other systems are onthisthing here is actually my laser printerwhich has a built-in print server butthere are no shares on itsoif i try to access it there's nothingthereso this nsa 320 is one of mynas boxesit's a very old nas it's about 10 yearsold so it doesn't support all of thenewestsort ofauthentication and encryption standardsi've got another nas called disk stationwhich is a synology box that i just gotlast year and this one is much moremodernum this one's mydesktop pcandyeah so if i select nsa 320 you can seea list of the shares that are viewableon iti'm currently authenticated for browsingusing the default guest id so you cansee here it shows thecurrentuser that's being used forauthenticationso if you don't specify anything it justdefaults to guest under whatever yourdefault domain is and the default domainis defined in your smb.confwhichis if necessary created by the by theinstallation of arcmapper uisoto show you how to manage differentcredentials i'm going to close out ofthis and show you thecredential managernow the credential manager is justcredman.exei've added the parameter slash keep toit this is an option thatkeeps the credential manager or log onscreen open um even after i've logged onby default it'll close the window afterlogging on but for the purpose of thisdemonstration i think it's easier tokeep it open so i've added thatparameterall right so this is what the credentialmanager's login screen looks likeit should look fairly familiari meanlog on screens generally aren't terriblyuh different from one anotherso i'm going to log on using a userthat's defined on my newersynology nas and i've called that userfile user just for the sake of this testso i'm going to keep the authenticationtype as ntlm the other option beingkerberosunless you have a kerberos kdc on yournetwork a lot most casual users probablywon't um ntlm is the defaultand if you don't know anything aboutkerberos just leave it like thatthe advanced button is only available ifkerberos is selected because it sets thenumber of kerberos options and thedomainnow the domain stringisn't actually that important if you'renot running on a centrally manageddomain like active directory or a sambaserver that's configured forto take the place of active directoryin a peer-to-peer network umthis is really just an identificationstring that lets you distinguish betweendifferent users that might for examplehave the same username let's say i'vegot a user called alex defined on thensa 320 nas and i've got another usercalled alex defined on the disk stationnas and for whatever reason i've giventhem different passwords i need to beable to distinguish those two from oneanother when selecting them so puttingthe domain string putting but givingthem a different domain string kind ofhelps allows me to do thatsoif you're logging on as an accountthat's defined on a specific box as i'mdoing i'm using file user which isspecifically defined on the disk stationnas so i don't have to do this but i ilike as a sort of habit just to use thename of that boxas the domain just to give it thatcontext as i say that's not necessaryyou can leave it at the default as longas all of your user namesare defined in the same place oryou don't have the same username withdifferent passwords somewhere on yournetworkso i'm now going to log onandit just says it's been successful andyou notice an active button has appearedhere and if i expand that you can seethis shows me all the currently activecredentials that i have so i now haveone active credential which is diskstation file user it's an ntlm typecredential and it's valid until shutdownall ntlm credentials will be valid untilshutdownkerberos credentials are valid until thekerberos ticket expiressowhat i will now is add a couple of otherusersthere is a user on my older nas calledlet's call it backup one i've created italreadyand i call it that because this is auser id that i can use for runningbackups because that's what i use thisnas for i use it to run my i used to zipup my osu system periodically copy itdown there soi'm going to set the domainjust to nsa 32 and again i could leaveit at thealt d01 domain if i wanted tobut i like to just use the the hostnameas the domainso i'm going to log on as thatand you can see i now have the seconduserand i'm going to log on as a third userhere and this timei've created a user called test user onmyubuntu vm with the kerberos kdc serverso i'm this time i'm going to selectkerberos i'm going to go into advancedyou cani don't knowwhatever ummost of the time you won't need to messwith these options uh if you don'tunderstand what they mean definitelydon't mess with them i i understand whatroughly half of them mean soit'sokay as you can see the domain haschanged to altsan.org that's the name ofmydefault realm in my kerberosconfiguration fileormy heimdall configuration file and thatagain is set up when you installheimdallwhich is the kerberos implementation foros2 that we haveso now i'm going to log on herelogin was successfuland now you can see there is a kerberoscredential hereokay so the next thing i'm going to dois i'm going to mount a connectionsoi'm going tomount one of the shares on my diskstation nasand i'm gonna mount it to drive xand i could just mount it to drive x asisbuti'm going to put it under thesubdirectory photo which is a nicefeature of the net drive samba pluginyou can mount to a subdirectory as wellas to the root directory so just checkthe options hereso this is a modern nas so i'm going tokeep encryption enabled i don't needntlmv1i'm going to leave the rest of theirdefaultsand i'm going to selectfile user on disk station because i knowthis user has permission to actuallymount this directorysothe station photo was successfullymountedall rightso if i now look at manage connectionsthis shows me all my currently activeconnections and you can see i've now gotx photoconnected to disk station photojust to prove itopen the drives object drive x directoryphotoandhere we havea bunch of photosuh i think i took most of these when iwas living in japanjust uha bit of a sampling here for youactually i think that one's in seoulum so it's thatso onethat oneah yes actually some of these are frommy korean trip that's a korean barbecueokay we're back in tokyoand there's a nice viewso as you can see yes thank youas you can seeremote access is working fine these thisdirectory is on mysynology nasno issues therenow i'm going to go back into thenetwork browserandlook at this it's changed to microbiostake it and the reason it does that isif you have an active kerberos ticket itwill the network browser willautomatically use that instead of theguest idbut in this particular case i want toauthenticate as file user becausei want to be able to see the shares onmy disk station nasas you can see i can see some serversshares because they're publicbut others i can't so i need to changeto a user if i want to look at the diskstation shares i need to change to auser that's valid on disk station so iwill go to network authenticate it letsme select a new logon if i want thedefault guest logon or one of theseexisting credentials that i've alreadycreated so i'll select file userenable encryption becausethe server requires it i believeokay so now you can see i'm nowauthenticated as the station file userand now i can see the share is on diskstationinterestingly i can't see the shares onnsa 320 anymore because this user is notdefined on nsa 320.so at this point i'm going to switchback toactually i'm going to switch to nsa 320backup oneand because this is an old mass i knowthat it doesn't support encryption soi'm going to turn that off so nowi can see the shares on nsa 320 againbut i can't see them on dislocationanymore because i'm not using that userid anymoresoyou can actually mount a share from hereso looking at the shares on nsa 320 iselect backup this is the drive that iuse for running my backups toright-click on it or i can go in hereand i'll select connect and this justopens the network dialogand again you select the user and inthis case because i was logged on asbackup one from the network browser itwas smart enough to pass that to theconnection dialogand it's pre-populated the share nameand i can choose where i want to mountit to and i'm also going to mount it todrive x but i'm going to put it ina subdirectory again now as you know ialready created the subdirectory photoand that's already in use if i try totype it inso i need to make sure i type in adifferent pathso i will use backupselect options and again this nas beingover 10 years old doesn't supportencryptionbut what i will doyou see this checkbox at the bottom savethis connection i'll check that and i'llshow you what happens when i do thatsoit's mounted that share and so now itgives me this dialog saying how i'masking me how i want to save thisconnectionso i can export it to a file in whichcase iam given a file dialog and i can choosewhere to file save this to or i can saveit as a restorable connectionand i can choose to save the passwordalong with the file or notobviously saving the password in thefile is somewhat insecureif at least if anybody has access tothis machine for the purpose of thisexample i am not going to save thepassword sosave as restorable connection withoutsaving the password and this just showsthe the details of the connection heresowhat happened well it saved theconnection as a restorable connectionand i'll show you what that means so ifi go into manage connectionsyou can see i now havethe two shares that i have mountedthey're showing under active connectionsthere's another tab here called savedconnectionsand this isa list of all the connections that ihave chosen to save and since i justchose to save the new backupshare as a as a saved connection it'sshowing up hereso i can alsosave a connection after the factfrom this page so i've already got asaved connection for xbackup i will alsosave the photo connectionso there's a save button hereand again i get the same dialog so iwill save as a restorable connection iwill not save the passwordokay if i go back into save connectionsnow you can see i have two savedconnections which just happen to be thesame as my active connectionsso what i'm going to do now is actuallydisconnect from both of these and againthis screen lets you disconnect yourmounted connection so i'm going todisconnect from photoi'm going to disconnect from backupso now i have no active connections buti still have the two saved connectionsso what can i do with these savedconnections wellas you can probably expect the restorebutton lets me restore one of theseconnectionsthe selected connectionif i want torestore all connections there's actuallya separate icon for that if i close outof here you see back in this folderthere's a restore connections icon andwhat this does is it reads all of thesesaved connections and it attempts torestore them all at once and the reasoni made this a separate icon isso that i can create a shadow of it inmy startup foldernow we don't do this by defaultyet i'm looking at ways to maybeprovide a configuration option to dothis but it's generally easy for anyuser to just create a shadow of thisobject in their startup folder if theywant to restore all connections on bootbut that's how you do it so if i runthis restore connections programrestored two connections if i go back tomanage connections you can see they'rebackandyep there they areall right now i'm going to go intocommand prompt hereand i'm going to show you quickly thenet command soas i mentionedthere are a few sub commands that i'vegot implemented in this new net commandreplacement so we've got net useand without any parameters it just showsyou what i have attached i could alsomount another share for example net usexvideonsa 320videothere it isi don't actually think i have anythingon that drive it's one of the built-inshares that came with the nas but i cando that from hereand if i go intomanaged connections it shows up theretooand also remove a connectionlike thatnow by default uh this uses the guest idsame as the network browseri couldand theni can use the same syntax for specifyinga user and password that the file andprint client snack command usedit's much the samethis is a quick overview of how the netuse command works if you've ever usedthe net command from ibm it should bepretty familiarthere are a few other options too likefor instance i exam added a couple ofswitches to provide new features likeusing a kerberos ticket or encryptingthe connectionso it's reasonably capablethe other net command here is net viewand this basically is a text version ofwhat the network browser shows you so itshows two work groups the the twoservers on the work group work group andthe three servers on the alt d01 workgroup andi can also view a specific serverand there are the shares on nsa 320.so what i'm going to finish up by doingis showing you how log off workssothe manage active credentials list showsall of the active credentials and if iwant to remove themi just select it and hit removeso in the case of a kerberos ticket thatactually destroys the ticketso i can no longer log on to anythingthat requires thatkerberosidand in the case of ntlm tickets it justpurges it from the memory cachenownotice that i've specifically chosen tocall this function remove and not logoff and i'll show you whysolog off that guyi should say remove that guyand remove this guyokay so what do you think's happened tomy connections wellthey're actually still therewhybecause deleting a credential doesn't doanything to the active connections thatyou established with that credentialbecause the credential is only usedby the net drive plug-in architecturethe credential is only used at themoment you first mount the sharesince the share is already mountedremoving the credential from the systemhas no effect on the currently mountedresources so i can stillaccessfiles on these sharesthat's just something to be aware oflogging off does not remove yourexisting connectionsand that's why i've tried i'm trying tomove away from the term logging off asfar as managing the active credentialsis concernedso i speak in terms of removing thecredentialif i want to actually disconnect theseshares i canjust disconnect them from hereand so nowthey're goneso that's a very sort of high rapid fireoverview ofthe new arkham mapper uiit may seem a bit involved but onceyou've used it a little it's actuallyquite straightforward and hopefullypeople will find it reasonably easy touse at least that's my hopeso thank you very much for your timeand hopefully i'll be able to takequestionsthank youokay well that was an update from arkhammapperfrom alexi guess that shows thatos2 can still innovatebychipping out certain components andputting some new stuff into place butstill has the look and feel of theoriginalum[Music]i did see that a couple of questionspop upsome of them are notarchimepa samba related others were soi'll justrepeat those questions herei think john eric larka and mikecolin both answered the same ques askthe same question will there also be anewer semba server coming with arc os5.1since we currently have 3625lewis rosenthal answered that that theserver tools are on the roadmapfollowing the release of samba server 4.look for both later in the 5.1 cycle soi haven't seen any otherspecific questions here regarding thearc mapperi guess that's a testimonial to how goodit was the demonstrationthanks for creating another innovativetool for os2andmaking it usable i'm just lookinglet's see herei have alex here by the way uh on skypeso if you have any questions for himuh let me know umi'm sure i explained everythingperfectly nobodyis missing anything rightmr faulty says i still think that the uicould be more integratedand use a kind of traffic light logicfor the activeness of thingsokayinterestingthe other thing is that here on the umlet's see herewhat happens to automatic restoreconnection in the startup folder when nocredentials are availableno logon i guess that the logon willjust fill mike calling is asking that inthe youtube chatumit'll just um do nothingit will do nothing no error messageyou'll just feel gracefullysecond i can double checkyeah it should justdo nothing fail gracefully it onlygives you an error message if it triesto attach something and actually failsoh another thing that i didn't mentionbut probably should have umwhen you go to restore a connection as imentioned you're not required to savethe password in the file so if you tryto restore a connection where thepassword is not in the file it willactually look through your activecredentials to see if there's a matchingcredential there already and if so it'lluse it you won't have to enter thepassword if the credentials specified inthe saved connection does not alreadyexist then it will prompt you for thatpassword but only one time so any futuretime that it needs that same credentialit's already got the password and it'screated the credential in thememory cache so we'll just use that inthe future soit's uh quite convenient i thinkokay thank you for that answer i see i'mjust as i said my head's spinning aroundfrom between three different chatwindows i see here thatmoritz moronsmoritz clarenbeck has a clarence bachhas a question are you planning to addquote do you want to disconnect sharewhen using the remove credentialsquestion mark umthat's still under consideration i wouldkind of prefer not to but it'sum it's a thought the thing isthecould be mounted resources that um arethey're queried from net drive becauseit's net drive that manages them soit's a littleinvolved it's fair bit of work toactually figure outif you disconnect a particularcredential whether there are anyuh resources currently using it youbasically have to go through allconnections that exist and checkeveryone's credentials to see if there'sa matchand i meanit's it's something that i could do i'mkind of waiting to see how people likethe current behavior before i decidewhether or not that's something i wantto implement if enough peopleseem to be asking for that feature i'llcertainly look at it welllooking looking at how the rest of theindustry does itif you delete credentials in windows ormac os best that i can tell theconnection stays alive until the nextreboot in other words they also didn'ttake the trouble to actuallydisconnect when the credentials are goneand the question is do you want to dothat automatically since there's also adetach button in the current archive iassume that also exists in your currentreplacement for thatuh yeah i mean the the disconnect uhbutton on the manageactive connections dialogueyeah as i say it's something i can lookat doing if people decide that they wantitand i think here's a question that ialready can answerbut i'll leave that to you oh by the wayon the youtube channeluhmatt walsh wants to thank you for theexcellent presentationumthere is a question from uh kathleenbriggsand the question is will you encryptpasswords in the future i thought thatwhen you enter passwords in arc mapperthey are already encrypted are they notnothey are they are obfuscated but theyare not encrypted okayso anybody who understands theobfuscation which is extremely trivial ishould i should mention um we'll easilybe able to just uh extract the passwordfrom themthere we are looking at ways of managingencryption as well as for the in-memorystore uh as you know the the ntlmpasswords are actually saved into sharedmemorysoi mean normally you can't access thatunless you write a program to do it butin theory if somebody got physicalaccess or i suppose remote access um totheum to your systemand they really knew what they weredoing they might be able to extract thepasswords from the active credentialsfrom shared memory and if you have atrap dump or something or uhsomething like thatin theorythey might also be exposed that way sothat's another reason that i'm certainlykeen to figure out a way of handlingencryption the problem with encryptionis where do you get the decryption keyfrom and how do you manage thatthat's a dilemma that i've been kind ofspinning around in my head for some timei haven't found an easy answer to it yetbut it is it's on the radarokayumokay i don't think i see other questionspopping up here let's see here there'snothing on the two irc chats hereum[Music]noi also see no more questions now let'ssee there were a couple of otherquestions hereum yeah that was all i alreadylewis already answered the questionabout the samba server so that one canbe taken off the list okay umi'm just checking againno there are no further questionsokay i just like to uh ask everybody fora virtual hand for virtual round ofapplause for alex because he's alwaysthe guy that comes up from myperspective with the uhlet's just say somewhat more intuitiveand more better lookingapplications on os2as a short reminder if anybody stillwants to have a free tour of the ibmtext mode lvm tool after we introducedmini lvm i think life got a whole loteasier for everybody and his new latestarca mapper replacement i think is a uhis a continuation of that traditionmaking os2 more user-friendly andlooking a bit better so thanks alex forcontinuing those efforts i think that'salso nice to say that for a changethank you umumi don't yeah okay there are no furtherquestions okay alex uh thank youuh there are still a couple of otherquestions that got us on the channelwhile while we had a breakand there was a question if umtrim support would be added to theoperating system that is more of aquestionforumfor arkanoa[Music]what i do know is that would need to bebuilt into the file system andpossibly also the storage drivers but idon't know soi don't know if trim support needs to bebuilt in um that's something that idon't know if lewis rosenthal or davidazeritz couldanswer that on the chatand look i think david was in was loggedonto one of theuh chat window so i don't know if hehears this question right nowso i will justprogress to the next question and see ifa question willif an answer will be given there wasalso the question that i read quicklywith the question ifodin 32 is usable to runwindows 9x applications on os2 foranybody who wants to experiment with itbe my guestbut it's bya far stretch not as good asumaswine on linux is soi keep seeing that question pop up in mymailbox also from time to time how can irunno98 of the windows applications willnot work or they'll have a prettyquick crash if they start up soit hasn't beenumit hasn't it hasn't been updated formore than over a decade so that's notgoing to bea feasible optioni have an answer here from david azaretzfrom arc noah and he says that trimneeds to be in the file system and thestorage driver sodavid can you comment on it if that'ssomething that you are going to look atorumoh there's also somebody called guest 57and he asks would it be possible towrite a ring zero driver to function asa credential storage hidden from memoryaccessible by ring 3 applications forthe network logonsoh alex already signed off but i cananswer that question for you it doesn'tmatter if the data is stored in ring 0or ring 3the problem is how is it encrypted andcan the data that is stored in memorycan it be decrypted so if you do amemory dump for example can that data beuh decodedand that's really the question so ringsring zero device driver willmost likely not fix thatumi also see an answer here from lewisrosenthal regarding the question fortrim support we have a ticket open foradding trim support we haven't yetexplored this however sothat's what the answer so far is for thetrim support question but i also get theimpression that we haven't seen a singlessd on os2dying attributably to the fact that trimsupport is missing if i'm wrong pleasetell us but i'm not aware of thatthere was also a question from a userwho asked if the os2 community had anyobjectionsuh regarding that who your why now has aproduct with the name os and then theslash missing two in iti think nobody caresi thinkabout five or five to eight years agoapple launched the product and martin ithink ether beater from os2 world knowsthatsome apple productsmade a whole lot of people enter i thinkos2 also some deviation into google anda lot of people ended up on os2 worldfor that reason but i could be wrongi think the only people that would careis the ibm legal department but i thinkin the united states the trademark foros2 has even now been dropped by ibm i'mnot certain if it's still in theibmtrademark in theunited states patent office trademarkdatabase soum[Music]yeah there is more feedback here on theencryptiondiscussionalex against writes the problem withencryption is what encryption key do youuse it has to be something that theprogram can automatically generate andno uh and no will be correctbecauseif you require the user to enter theencryption key every timeit kind of defeats the purpose of savingthe password in the firstplaceand yeah david as awareness from arcnoah effectively writes the same on theother irc channel implementation ofcredential storage is not the issuethe issue is acquiring the keys todecrypt them again soand there was one last question that ihave here that was also asked during thebreakon theum irs on the youtube chat and i need toscroll back herefor a portion and it is that somebody ohyeah here andreas asks is there a wayto limit the time of a check disk when ineed to reboot after a crash in my caseit takes about 20 minutes each timethe standard answerno ticket no issuehere's here's an example why we needtickets your question is valid can wespeed it up butare you using hpfs volumes are you usingjfs i mean hpfs on a lot of if you havea lot of hpfs volumesinstalled on your system you can getlarge check disk times becausehpfs doesn't have is not a journalingfile systemjfs on the other hand is a journalingfile system so if in most cases if isummarize it correctly if the journallog of the file system is correct itwill read the journaling log and markthe partition as cleanhowever depending on if the journalinglog on the jfs partition is marked asnot being reliable then you get a fullcheck disk and that can take some timesoagain with all of these things isand i think martinumitabeda also mentioned that recently onos2 world use david as where it's histest log programtocollect data on the system i've seen acouple of questions here regarding ihave this issue and this is happeningbut it's very useful for either in aticket or in a forum to have more dataif you ask my system freezes what's thecause wellit's raining outside why is it rainingsoi'm sorry if it sounds a bit simple butin a lot of these technical cases weneed data to help you soumyes robert stratton issays looks like that os2word was cancelled by the uspto on the24th of april 2020but still that doesn't mean that you canuse it because that still means that ibmhas been using it in daily businesstraffic so i think that also stillprovides some form oflegal ownership of itumi see that there areno further questions here there is somediscussion happening on the irc channelregarding those keysi'm not going to go into that becausethis is not a technical workshopi'd like to move on to the uh nextportion of the uhto the next warp stock presentation andthat is theuh web browserumi'd like to ask you guys if youcurrently have uh websites that youcannot access with firefox[Music]dmitrihas made ai've done an interview with dmitrykuminov from bitwiseworks he was notable to joinumwartstock sylvan sharer was also notable to join he has been very busyhe wanted to make time butas you might understand the coronacrisis for some people has been veryseveresylvan his businesses were impacted ican just honestly say very badly bycorona and now it's the opposite nowhe's extremely busy he also has a divingschool in switzerlandandher weak bowen find frombitwise works was unable to attenddue to personal reasons beyond hiscontrolsocould you please run the interview withdmitry comey not coming offand that takes about half an hour hewill explain all of the developmentsfor the browser the current financialposition ofbitwise worksand what the status is of the browserand as i said i'd like you to collectsome of thewebsites that didn't work that don'twork anymore with firefox and after thisinterview with dimitri that takes about30 minutes i will give a livedemonstration on our live os2 system notrunning in the vmwith the latest version of the browsersocollect them and then i can show you ifthe browser can accept thosethose websites that currently don't workin firefox can you please start thevideohello everybody welcome to uh warp stock2021 warps of europeumthis is a pre-recorded interview withdmitry kuminovfrom bitwise works he's been one of thepeople that have beenperforming a lot of uh ports to os2 fromother platforms such as linuxhe's been involved with a lot ofprojects over the years he works forbitwise works in austria from which youhopefully by now have heardbasically i considered two importantparties in the os2 community that'sarkanova doing the uhthe os development and the driver stuffsuch asthe upcoming uefi and gpt which is veryinteresting to keep ost running oncurrent hardware and then there'sbitwise works who are doing a lot of thedevelopment uh for porting software toos2 maintaining toolsthere are other people in the communitywho also contributed this process paulsmedleypeople like albert paulum i forgot his name our friend fromsouth koreahe also does portsthen there is one of yourrussianuh country fellowmen who lives onzachelin island i've got his name hedoes the remote destal port but thiswhole eco system basically depends oneach other people port software and somepeople use for example the librariesthat bitwise worksportsumover the last three years thebitwise works has been working onporting qtand thedll that is part of that called qtwebkit which is the newrendering engine that turns a web pageintoa page into your web browserandlast yearat warp stockeurope 2020 we also gave a demonstrationof theqt test browserand dimitri is here first of all toexplainuh what was doneuh in the lastyearumi think by now you guys maintain about300 different dlls roughly on os2 whichare inrpmnetlabs.orgi think it's also important to emphasizethatall of those dlls come from bitwiseworks but we will get back to that laterso dmitry what have you been working onfor the last year roughlyrelated to the browseruh first of all hello everyoneuh yeah there there has been quite a lotgoing on uh under the hood hereuh first of all we have updated ourlargest and most important libraries andtools likegcc version nineuh libsy and its little brother lipsy xand actually we did it uh many times andsome more updates to these two keylibraries are still pending andvirtually anyosu software out theredepends on these two libraries nowadaysthen we updated python version 2 to thelatest buildandmost importantly ported python version 3to os2 finallyboththe latest python 2 and the new python 3are already provided as rpmsrpm packages whichcan be easily installedat the same time and perfectly coexiston the same machineand besides that uh for the last year weupdated more than 50 software packagesto the recent versionsincluding bash unzip b thread pearl sdl2open ssl icu which is a very importantlibrary for handling international textcups which is a set of printer tools andlibraries toto have a printer and to be able toprint from os2 to modern printers thenit's popular then it's dbusthen it's a new version of cacertificates which are needed for safessl connections and then there is opensshfinally the firstrpm which actually works then there isother conf and yam and many many otherlibrariessome of these packages never existedbefore like d-bus for example so theywere our newportandum to say the truth most of thissoftware was needed to portthe new version of qt to os2 which weuh also did this yearwe updated qt from version5.13.1to version 5.15.2including of course theqt web engine module which provides anewer version of the chromiumweb engine from google which is nowafter this last update is at version 83.this is not the latest version fromgoogle but it'srelatively uh recent uh the most recentone in chrome itself is version 90 rightnow so we are not that far away and asroderick mentioned chromium and theqt web engine module is the keypiece in order to have a new browser onos2uh it's also worth mentioning thatqt[Music]5.15.2 is officially thelatest version from the qt companyin the5 series available as open source andfree of chargetheyalso have version 5.50right nowthat istwo least significant numbers ahead ofwhat we have on os2but it's only available to commercialcustomersso was the decision of uh of the companyand it has been widely criticized by thecommunity since it was uhuh announced last year but they didn'tchange uh their decision for some reasonuh the only thing they changed afterthat is uh letting people take thelatest qt web engine sourcesuh from their git repositories uh freeof chargeuh including uh chromium version 87and then compile and build it on theirown if they want to havethe latest version of this specificmodulein the five seriesthis procedure is not available for anyother module like qt based for instanceand all the rest as far as i knowthey made this exception for qt webengine because of some licensingrequirements in the chromium codeand we might considerupdating this module later on but it'san open question for now because offinancial reasons and we will come tothat topic laterand i would also like to mentionthat the main motivation of the qtcompany to introduce this restriction tolimit the further updates ofuh this v5 series tothe general public uh making it acommercialcommercial service is as far as i knowto force people touse the latest series of qut uh versionsixbut the fun thing is that the qgisversion 6 still lacks some c plus plusmodulescompared to whatto what qte5 has and qt web engine isone of these modules which aremissing in qt6soeven if it's not too too hard to portqt6 to os2 it makes no sense right nowbecausewe will not get what we have in qdb5so what we are doing currently currentlywe are fixing some new regressions inchromium after updating qt web engine toversion 5.15 and once we finish thatwe will build the latest version of thereal web browser called authorwhich specifically requires qt 5.15 andit was the main reasonwe updated qt in the first placei guess you already heard about authorbecausea couple of months ago i made a testbuild of it using the older qt and usingconsequently the older version of authoritselfjust as a proof of concept and itgenerally worksso now we are once we finish uh theall the glitches in the in the currentuh chromium build on os2we will port the we will build thelatest uh version of author to us tooand it will be also available for uhgeneral publicuh so that's basically it uhthat's that's all we did in the lastyear since the last works of europe lastyeari wanted to zoom in for a moment on acouple of itemsthathave been passed in that have beendiscussed in the pastumwould you agree with me that by nowfirefox 45 for visiting a lot of webpages is rendered basically uselessyeah as i already mentioned many times ithink it's useless to continue to tocontinue os2 development offirefox because it's justhardly maintainable nowadays compared tochromiumuh first of all there are much morepeople uh working on chromium than onfirefox nowadays it has bettertest coverage it has better[Music]better debugging and etc etc so theoverall quality of the code is higherthan in firefox and firefoxcommands still contains some parts from80s from thenetscape navigator timesand theyalso do some experiments with the rustthere soso it'si think it's really it really makes nosense tocontinue working on firefox uh for os2chromium is much moreis much better choice here for for manyreasonsand just to emphasize it it wasdiscussed and discussed in the past thatwe could maybe consider using alternatebrowsers that are that areuh based on the firefox engine of olderbuilds before rustbutthe real question is there you knowhow long is it going to take before theyneed to start porting their rust codethe other thing that you just mentionedis that the market share of firefox hasbeen dropping like a brick uh it used tobe highbutto be honest i don't know how long it'sgonna takeif five years ago you would have calledyour bank and said i'm using firefoxthey will support they would support itbutthe chromium engine that's part of thechrome web browser and microsoft edgethose two browsers have a market shareof plus eighty percentlast time i checked firefox was at amarket share ofabout five percent but maybe thosenumbers are not really correctand then there's the real question thatwhy we started this whole journeytogether with the community dimitrinow that we have a portable version ofthe webkit the of the new webkit dll isit easier it's still work that'srequired but is it easier to port newbuilds because i clearly remember thatwhen you you were working on firefox 45one of your complaints was that it wasdriving you absolutely nuts how manychanges were in the code and it was justabout completely impossible to keeptrack and that you were basically almostworking for one year to port a new buildof the browser because of all of thechanges that had to be that toaccommodatethe firefox 45 build on os2is that now improved with the new webkitportyes definitely it's much much easier tomaintain the chromium source codebecause it's more modernuhit's a newer project and they userecent technologies there to develop itso it's much more it's much easier towork with it and it's more it'sgenerally more stable and they arenot changing things uh that uhseriously like they do it in firefoxbecause in firefox they try to keep upwith theuhcurrent times and uhand in and put all this new stuff allthese new standards in in the firefoxcode base and thechromium code base is already made uhaccording to the to all these newstandards so they don't changethings that uh often there so and forthis reason it's much easier touhto compile new versions and to align newversions to os2 so i basically spentlikeless than two months i guess uh whenswitching from chromium 80from chromium 77 which we had in qt5.13 to chromium83 which we have nowit wasbarely two months and well i still needto iron out some thingsthere but i don't expect it will takethat much at least not that not as muchas it took uh with firefox not a year orsomething like that much less of courseso yes it's a big improvement andchromium is pretty much dominantand nowadays so it was a good choice iguess it was a right move to switch fromfirefox toqt web engine which has chromium underthe hoodokay umlet's see hereumwhere is it i've got some notes herethat i'm looking atnow one of the things that people keptasking and it's a justified question whyit took so long to port it buti think we can both honestly open sayandthat shouldn't come as a shock toanybody os2 is showing its age it's thatsimple the os is 30 years old i thinkarc nova has done a uha breathtaking job i mean we've got acpiwe've even now got uefi in a form of gpdsupportwhich is wellkind of mind-blowing that it worksbut you also had tojump through a lot of hoops to get it towork i'm just emphasizing this questionbecauseone of the things that you explained tome is that basically forthe chromium code to work on os2 you hadto implement a lot of code that normallyis provided by the linux kernel toperform memory managementan inter-process communicationthat wasn't there and you had to putthat into the lipsian and or lip cx dllsi think that overall took you aboutthree to four months just alone to dothatyes something like that indeed chromiumuses uhuh a lot of ipc inter processcommunication because it's a multi it'sa multi-process product it usesprocesses toto do stuff rather than threads as manyusual applications do there's a thereare many benefits of of this approachbut anyway itneeds astable ipc inter-process communicationin order for these processes tocooperateand in chromium they useshared memory for that purposeand weand the os2 kernel simply lacks thenecessary functionality in terms ofsharingshared memory handles andproviding needed access to the sharedmemory and all these other things sothis is what i had to implement fromscratch on top of what we have and placeit in the user land in the ellipse xlibrary which is inan extension which is the bitwise xworks extension to leap cand besides that besides providingmodern shared memory operations i alsohad to provide sharing ofsockets between processors it's notavailable out of the box neither inellipses nor in eos ii kernel of coursewell there is away to sharesockets in the tcp stack and this iswhat i actually used for that but it'snot that straightforward andit has never supported by lipsyuh so i had to add this support thereand now we can share uhsockets open opened in one process uhwith some other process so that it coulduse them for inter-process communicationthis is what i already did and yestogether with the shared memory task ittook aboutthree or four months something like thatand besides that speaking of this speedof doing something on os2 it's importantto keep in mind that uhthatall these tools we need for thedevelopment like the uh like gcc likethis plus plus compiler like the toolchain like linkersand of course like all these librariesuh you need like libraries to work withopen with ssl connections with thevideos with audio withinternationalization and all other stuffwe have to do all these librariesourselves as well becauseno one out there supports always twoversions of these libraries there issimply no one doing it no one caringabout osu anymore some uhit's it's actuallya task for me and for silvan and forother guys out there who who help us alot to take all these libraries alignthem to os2 and build them on os2 andstarting from the compiler so we have tomaintain the compiler itself we cannotjust takeum usable version from someone and startbuilding uh programs no it's impossiblebut first we need to take the sources ofthe compiler then we need to port thosenew parts to osucompile it build it test it and onlythen we will be able to build otherprograms with this compiler it's areally long journey so it should bestated reallyclearly thatthis is the only road we have right nowthere is no one besides us working on nos2 versions of anything yeah there werealso some crash questions which in mybookwere sometimes even worded as criticismor lack of a good overview of theoverall projectithink i can saysay honestly thatthose peopleare clueless what they're talking aboutwhat i mean with that specifically isthatthe chromium project the webkit dll isabsolutely humongous when you started onthis was it possible for you as a singleone-man porter to oversee all of thepotential pitfalls that you that youcould potentially walk intono of course not and the the fun thinghere is that in order to estimate thenumber of work hours i would basicallyhave to spend that number of work hoursto learn this code it'sit's actually very simple to understandif you think about that so the cost ofestimating here equals the cost of doingthejob doneso and and this and of course withoutestimating you don't know the all thedetails and you cannotpredict uhclose enough what how many how manyhours or how many weeks or how manymonths it will require or even sometimeshow many years until youdo it it's the it's it's the trick hereyou don't know it until you do itbecause it's the system is so complexand uh there is no other way to predictit just to emphasize for everybody sothat they can get a slight feeling ofhow big the dll isthe webkit dllit's it's about 250 megabytes in sizeit's huge is that with or without lxcompressionuh it's uh it's with it's with it's withit's without the compression yes it'sokay without the compression and withoutthe debugging information this is alsoimportant so it's just pure codeit's uh c plus plus code and data andand it's about uh 200 megabytes or evenmore in sizei think it's the biggest dll os2 hasever seenyeah yeah and uh it was actually alreadya surprise that the us2 kernel was ableto load it at oncebut notbefore weenabled loading the code segment highinto the high memorybefore that it was notpossible to load it so we had toto use this ability here because thereis just uh too many things in that dllso it's impossible to load to load itlowwhich actually brings us to the nextstep which are the system requirementsi think you would agree with me afterall the testing that i did is that youat least need a system with three tofour gigs of ram the maximum that thekernel can provide and not a single coresystem you can use it but i think you'lljust be grinding your teeth to dustbecause the browser requires a lot ofcpu powerit'sit it's a beast it andthe bottom line is is that it's a pitythat we cannot get a lightweight browseronto os2but i think this was the onlypractical way out for a small communitylike us to get a decent standardgrade browser again again you know whendid firefox45.9 when did it go out of support withthe mozilla foundation i think it wasseptember 2017off the top of my headthis is what i remember as well2017 yes sosomething like that stripping thecalendar away that means that it's nowfour or five years out of support almostyeah exactlyand we can't have a light browser justinstall some old version of an escapenavigatorit's a light browser compared toanything else like fromfirefox or chromium but this browserwill not be able to do a thing nowadaysjust because the technology went uh muchfurtherand uh there are there are many new newstandardsmany new technologies thatmany modern websites use and there'sjust no way uh to go without them thisis one of the reasons and another reasonofhaving theserelatively high requirements regardingthe memory and the cpu poweris the fact that uhmost systems out there are already mostmost computers out there including themobile devices are 64-bitsystemsand of coursemany uhsoftware isoriented to 64 bitsand chromium is not an exception herethey write their code they add newfeatures with the 64 bits in mindand uh it's actually a miracle that isstill built on 32 bits machines it'sreally it's it's really a miracle and weare very lucky because osu is still 32billion so we are very likely that thereissome effort to steal support uh 32 bitsin the chromium code basebutthey use a lot of memory uhin the chromium when they in thechromium sources when they uh render webpages and do other stuffand of course they need the really wideaddressing andin these terms uh 64 bits is verylimiting to osuto chromium so it's not a surprise thatit's pushing always two to its real reallimits in terms of memory and cpu powersoanyone should just accept thatas a matter of fact there is simply noother way and that's still a miracle itworkswell i've been talking to steve stevenlevine about this and there might besome ways to reduce the memoryconsumption but those are things thatare stillbeing discussed at the water coolerbut first we want to get this browserout into people and i think the firststep is going to bea beta that's going to be distributed touhthe first set of people because we firstneeded testedthe thing that i also like to mention isthat basicallyout of the boxthewebkit dll will be marked to load highby defaultthat means that that means thatthe only way to get this to workis that you will that the only supportedos will be arc os effectively becausethat kernel has the rightumthe right support for itum and yeah we'll need to to set theirvirtual address limit to the maximum tothree to three gigabytes as well this isa this is simply a requirement foruh qtu app engine wellthat's actually no longer required withthe latest uh kernel update that'scomingah okay that's so there was some fix tothat but still but it's still uhit uhdirectly defines how many tabs you willbe able to openmaybe ifas youas you say uhsome bugs were fixed in the kernel andit generally works you will still not beable to open i guess you will you canyou will be able to open like one or twoor three tabs withuhwith lower virtual address limit valuesbecauseeach uhis each tabfor example each youtube tab requireslike four megabytes ofmemory i've been running it with 2048and i was able to open up five or sixtabs simultaneously with the simple testbrowser so it's uhit's not that goodit's not that bad okay but it reallydepends onhow heavythese tabs are if it's youtube orsomething as heavy as youtube well youwill just get you will just get fewer ofthem so there is a direct correspondencebetweenuh the amount of uh system resourceschromium will have and the value of thisof this virtualaddresslimit settingthere is one other thing there is oneelephant in the room that needs to beaddressedand that is the financial position ofbitwise worksyeah that's truei promisewe will come to that later sohere we are yes we are really really lowon fundingnowadays uh and it'sthat low that i had toreduce my work my work hours for was touhto basically like 30 percent of myuh full time so this is what i had to dobecause i have to do some other stuff tohave money for living apparentlyand uh given the situation uh with thedonations with the subscriptions we justdo not have enough money to workfull-time onall this stuff anymore yeah and i'd liketo emphasize here thati think dmitry i discussed that with youi discussed how i researched theuh figures to try and geta form of an impression how many peoplethere are i think that the current osucommunity there areroughly a few thousand private userswe base that on the fact that we lookedat how many people connected with thearkanoa package manager therpmnetlabs.org and over a period ofabout six weeks we found five to 600unique ipaddresses um i think dmitry you wouldagree with me thata large chunk of the moneycame viavoiceforfor keeping thefunding goingand voice has about100 email addresses in its donationdatabasei thinki think you can already draw out whatthe conclusion isthe community is effectively having adonation rate of between five to fifteenpercent and the rest of the people aredownloading these packages free ofchargeand it's a free world but people shouldunderstand what the ramifications are ofnot sponsoring and it's happening rightnowdevelopment is slowing down and i willput up some pie charts after thispresentation laterto make these figures clearit is very difficult to see how manyprivate os2 users there are out therebut based on those numbers at netlabson the amount of ip addresses i wouldsay that there are many more users outthere because not everybody runs arc nowa package manager on a daily basisand second[Music]not everybody even knows that it's therein the system setup folder so that's whyi'm estimating that there are probably afew thousand users out thereand everybody benefits from this work soandwhat you also know dmitry is thatrecently a couple of theloyal donators that provided a reallarge chunk of money have steppedforward publicly on os2 world i'm notgoing to mention their names here but ofthose about 100 donorsat least 50 to 60 percent comes off aneven smaller group of about 10 people ofthose 100 soyes it's pretty evident thata large portion of the money that wasdonated to bitwise works comes from acore group of about 10 donorsand i know that sylvan in 2020 put inout of his own pocket 7 000 euros extrato keep dmitri working at least i thinkit was even more butwell it's better to ask silva because idon't know the exact numbers but yeahhis contribution was really significantas wellinto his own company basically which isnon-profitableuh well it's not a surprise i guessit's it's a german gay mbr which isbasically equal to an english limitedcompany butuhit's it's it's it's effectively ran as anon-profit anddimitriis the only full-time employeeuh hurric bowen finds ken can currentlynot contributed due topersonalreasons beyond his controlum so yeah and sylvan is currently verybusy that is why he didn't have time foruh a net lapse for sorry for a bit for awarp stop presentation so yeah he's alsobusy with surviving of course yesuh we can say confidently that uhuhsylvan has been hit economically veryhard with his companies due to thecorona crisisand we are certainly not the only onesthat uhthat have felt the blow in certainsectors of the economy soum i'm hoping that that kind of clearsup uh after this video i willi will try later this evening to do ademonstration of the new browser theauto browser the beta that i haveand i will try and put together someslides showing where the donationnumbers come fromso that people can thoroughly understandthat we need more peopleto contributeuhto the porting of software on os2because i think dimitri that you willagree with me based on the numbers thati presented is that there is simply adisconnect to the amount of peopledownloading and the people that aredonating i think it's fair to say thattheuhthata lot of people are not aware of thefact that the free software comes fromsomewhere and that only a few people arefinancially contributing to thati think that they aremaybe they are aware about that but notdo not care that much about that i don'tknow maybe they justthink that it it wasresolved somehow in the past and willget resolved again without theirinvolvement or something like that wellit's a fair thought but anywaywe arewhere we are right nowour funding is extremely low and i hadto reduce the number of uh hours i canspend onuh osu and on chromium and on qt and allother things we we dotwiceokay well i hope that message sends outa loud and clear signal umit's the truth it might hurt butyeah i can't bring it inin any other way so i'd like to thankyou for your timeuma pity you can't be there tomorrow sodmitry will not be available to us toanswer questionsumbut uh i will do my best to answer thequestions and any other questions thatcan't be answered i will need to be sentto uh bitwiseworks via email then yeahof course sureokay yeah i think thank you everyone itwas a really nice to talk to yousee you soon somewhereokaythank you dmitry for your time and uhtake care stay healthy goodbye thank youbyeokay wellthat was maybe a bit of along interviewbut i hope that kind of gives a insightinwhere we are with the new browser as isaid i've got it running on the systemand just to clarify i've made a threeslide presentationuh explaining theuhwhat the call for more people to sponsorbitwise works is actually based onbitwise works has collected roughlyfrom the community about47 000 euros over the last approximatelytwo and a half to three yearswhat you see here in this pie chart isthe percentage of sponsorship that camevia voicethe dutch always to voice foundationwhat this insight gives is that becausewe collect a large portion of thefunding between50 and 60 percent of the f of the totalamount came fire owes to voicewe can state with a high certainty howmany sponsors there have actually beenas you can see that's over 60 can you goto the next slide pleasenow the thing is it's hard toestimate um[Music]how many os 2 users there areas you know i've worked at mensis untilcirca 2013 and we had exactly the sameissue we don't know how many commercialusers there were at the time and howmany private users that's totallyunknown and i when working onsponsorship for bitwise worksi've kept pondering like you knowhow can i get a feel for how many usersthere arenow as you know arcanoaships and provides a free version of itspackage called arcanoa package managerwhich is a graphical user interface forthe rpm command line you can also do itfrom the command linethe arc nova package manager just like abrowser has a specialid that it sends a text string toidentify itself to a web serverand in june 2020 i asked adrian if wecould analyze the logs to see how manypeople were actually using arc noaapackage managerbecause what a lot of peoplefrom my perspective at least do not seemto realize is that rpmnetlabs.orgis filled for 95 percent with updatesthat are coming from bitwise worksover in a period of six weeks timewe saw that there were about five to 600unique users or ip addressesnowthe thing isi get the sincere impression that a lotof users are not starting up arc novapackage manager or that it doesn't evenexisti base that on my experience sometimesat warp stock but also atalways dutch os 2 user group meetingsis that is that representative data idon't know but as you guess in thiswhole discussion it's hard to come byhard datathe[Music]so the numbers that we have here make meconsider that there are probably a fewfew thousandprivate os2 users that are usingos2now the thing thatis sopressing is thateverybody is free to do what he wantsbutthis is kind of a call out to thecommunity and you know we need morepeople to make a contributionto keep this work going a portion of theporting work is being done like peoplelike paul smedley but another portion isalso being done by other people and asyou heard they are maintaining about 300librarieson osu and keeping them current couldyou go to the next slide pleasenow here's the thing that is a bitconcerning so we've gota few hundred users in a summer breakthat are using arcanoa package managerand the uh and we collect the bulk ofthe money the sponsor bitwise worksthe voice foundation that is andeffectively we've got about 100 emailaddressesandof those 100 sponsorsthe vast majority of that large chunk ofmoney that voice donated came fromapproximatelyumuh10uhfrom about 10 users individuals thatcontributed heavily there has been onesponsor that contributed anywhere fromten to fifteen thousand dollarsso basically we've got a sponsor ratioof 20 to onesoi'd now switch over to theactual demonstrationbut if people would like to make adonation for a projectplease go todonation.alwaystovoice.org it's notuh plural it's donation.ostovoice.org[Music]let's see here okay yes if you canswitch to theto theyeah thank youokay what you see here running is aactual system with os2 on it it has uheight cores in italex just um[Music]um[Music]pointed out to a couple of websites thathe asked me to try soi will start the other browser here thisis actually no longer theumthis is actually not yet public this isthe author browser i must tell you itcan still crash but that's moreattributable tobugs that still need to be worked outbut this is the actual new browserrunninghere you can see that it's usingthealmost very latest qt there is a newversion of the qt browserthatum[Music]here'sthe about windowthe other browserso this is what it was all about to geta new browser on os2let's see hereif i go for example towww.github.comthat's one of the websites that alextaylorsuggestedit doesn't like it let's try it again iactually during the video loaded it uplet's try againthere we goand i think that if you look here ittakes a little time to load but it seemsthat the website is hugeyou can actually see this is the thisrotating globe that's typical html5artifactsuh so here you can actually see theuhyou can actually see the the new browseri can also scroll down and as you cansee here it's it's loaded with with newuhwith new graphicaluh spiced up imagesas you can see there's all these windowsshowing textsand this is what we i call or refer tobasically as html5 this is the new typeofof user interfaces that you will startseeing more and more common now one ofthe reasons that the system requirementsare that high is becausethe web browser requires a lot of humanrequires a lot ofumhas a lot of resources needed but alsothe websites themselves have turned intowellfat pigs some of the sites that idownloadedsend a couple of megabytes of html datathat all need to berenderedso here you can see the github page ifthere are any other suggestions uh justlet me knowbut i there was a question if i could goto dropbox nowi do not sadly have a dropbox accountherebut i can try opening iti just tried it and it came up withoutany issuethere it goes againsorry i can't i can barely see theletters because i am looking at a screenthat from uh from the device thatcaptures the video so i've got a verytiny screen to look atthere we gothere we've got dropbox but i don't havean account to uhto log in one of the other websitesthat's now also working[Music]ispatreon that also didn't use the workanymore i can log on to that pages likelinkedin started workingi'll demonstrate youtube in a secondwhich also runs pretty smoothlyanother bit of us never seenum now here's the other thing that was arequest from alex taylor usedrivegoogle.combut i don't currentlyi'm trying to remember what mycredentials were forgoogleyeah i don't know why this is settingit's probably i don't know why butit's sorry it's setting it automaticallyto dutch i don't know why it does itprobably does that based on the ipaddress that i have here in thenetherlandsnow if i go to driveoh it's asking me to allow a pop-upokay well you know what um i'll just tryand log in here[Music]okayhmmhere we can actually see thevideo stream itselfnow for alex's information it i did tryuhtvtroops.organd the browser choked on it so i willreport that to dmitrythe upcoming browserumuhwill be released via rpm this time andthat will finally be the first browserthat will berpm uhdistributedand also the upcoming updates will bedistributed uh in that era in that waysoumwell that concludes thisweb browser updatei'm hoping actually that dmitry stillneeds one to two weeks to getuh the latest qt code compilingumanduh then we can go for a beta to a firstgroup of people to start testing it on awider set of systemsand i'd like to know if there areany questionsi am seeing here some questions poppingup uh on the youtube channeluh whereuh was asked for a new chromium browserwell this browser is chromium based it'susing the same rendering engineand actually while you were not seeingthis forduring the presentation of during thelunch breaki actually had it set to play theyoutube channel for 45 minutes so itdidn't crash in that time butlet's see here are there any otherquestionsum[Music]yeah i'm seeing if people askingif we could make a 64-bit os2 kernelwellthat discussion has been has beenfloating around through the communityfor the last 10 to 15 yearsif ibm wouldn't give arcanova the sourcecodeforget about itthe physical dress extensionwould be great buti go by what stephen levine says and itcould be donebut the way i interpret personally hisexplanation isuh consider it wishful thinkingwhat might be possible and that's one ofthe things that i'm looking into withuhbitwise works is the possibility thatthe large programs can somehow utilizethe memorythat the arc os loader above the 4gigabyte boundarymakesavailable whether that can be doneis another thingyes and i see mr faulty here providinghis usual enlightening comments and sayinstall os arc os twice to get 64 bitsand that'si think that i think mr faulty sinceyou've been working that long at thehelp desk functions and i know how longyou've been doing it your brain has beenfried but that's the only way to getthrough help desk life you have mysympathysoi'm just looking here at the questionsthat popped up umare there any questions regarding thisnew browser i know it has been a longtime coming but you can now see itrunning is it actually still running oris the frameyeah the problem is that all the framegrabber also sometimes uh kicks the canoh it seems that the grabber hasnever mindthe usual stuffokay umare there any questions about the newbrowserorif not thenyour roon and i willwill set up the equipment hereforthe next session in the last session ofwarp stockuh in this case from uhfrom ben rietgrouksowe will haveumuhwe will have a recess for about fiveminutes so that we can set upthe uh presentation foruh benry bruce presentationso we'll now have a short recessthank you for your timecheck them outsoum as you might havenowi'll introduce you umone of the people in the os2 communitywho has been doing uh softwaredevelopment for os2 for years is uhsomebody called ben reedruck he workedon airboot andseveral other projectsandhe is actually of the he actually hastheobjective to come up with a method todevelop software in a completelydifferent way one of the issues is thatthewriting code for os2 is pretty difficultanduhben is looking in ways tomake that work in a different fashionand basically he wants to work with thatin the form of objects if i can if isummarize that correctly but ben is onthe phone right now andhe will give his presentation via aother system actually he will be usingthe auto browser sothen the floor is yours and you'reyou're now liveokay thank youi have in my right ear theyoutube presentation left or i hear youon the phone so there's aquite a delayit's about 20 to 30 seconds soyeah yeah i think so i think soso okaymy name is ben ricockasit states hereandi will givea littlefly around in the nutshelli am i'm just now fiddling with thescreen update of cnc so just a momentpleasedo you want me to open the first tab iknow which order you want to do them inyeah can you click on nature yeah i'lldo thatit's openokayokay well just a moment because now ihave to get my browser here on the localsiteokayso my my first almost two was version1.1 extended editionthat wasback in the 80sandthe extendededition included a database managerand at that timei had evenschooland we hadassignments where weneeded to create programs using sql sqlandi discovered that with os2 and thedatabase manager you could justput youryourthings that you wanted in somesome clearly form and then it wouldgenerate a sql code for youso it was very interesting because weall got eighth on our on our assignmentsbut to make a long story short it was myfirst encounter with generating codefrom a more abstract fuelnow i also like tux and beastytux because it is just a powerful systemand beasty because it's a very cleansystemif you don't know these names of coursei mean linux and bsdand for some time i've beencontemplating based on this generationfrom a viewit's called a generation from a view onhow to get such stuff running on ourstooand to make it easier todevelop software on ours tosupport andalso to improve cooperationnow the idea is in fact model drivenengineeringand that means thatyou have a model whichkind of expressesscenarios and resources and whateverthat can be processed and which cangenerate several kinds of sources likelike program sources c dot dot c plusplus sourcesother languages and especiallyobject-oriented languagesone very good example of of howmodel-driven engineering is worked outis in the eclipse modeling frameworkworkfor people familiar with eclipsethey might know that thetotal core ofeclipse itself is actuallya very small runtimebased on something called epinoxandthat the complete functionality ofeclipseis actually provided byby pluginsand these plugins are dynamicallyloadable selectable and whateverandthat makes it very um[Music]veryhandy tohaveummultipleintegrated development environmentsbased on the same runtimenow we don't have eclipse running on os2because it requiresmodifications to the opensubsystembutsince many of the models of eclipse areactually xml basedwhich obviously can processit is possible to usethe eclipse technology on our screen toa fair amount ofextentso it has been working on iscalled modernmodel driven engineering for our schoolandit is uh catch off as actually fora kind of factory enginewhere you put in modelswhich generatessource powder and other resources whichcan thenbe builtand which can then be packaged and madeavailable for installationyou want to go to the next portionyeah talking picturesi'll do that um or if can you see itthat would be betterit's updatedokay okay now i have to see if theminimize maximizer helps my case hereit does so i will be minimizing andmaximizing to get my view here correctlyokaytalking picturesif one gets a document with a lot oftextandlots of paragraphs then you have to readthat and no app catchersand so it's difficulttocommunicatea kind of concepta picture says more than a thousandwordstherefore i will be using picturesbut these pictures also come from a kindof free form modeland this free form model is a planningmind mapand that can be processed if so desiredusing xsltwhichcan generate also sources and scenariosand other stuffso in a kind of wayif we remember what i told you aboutthis database engine i used in thein the 80sthis is actuallya kind of visual representationwhich is easy to make by everybody wecan generate the complex code and borderframeworkswhich can then bebuilt using the development toolsthe menthol is absolutely from idea torealization which means thatyou have an ideayou go to the drawing boardand that is a kind of mind map whereyou're visuallywork with compounds that you connect toeach otherand for those of you who are familiarwith visual ageand maybe aware of the visual builderespecially the one in version 4whichhad kind of the sameconcept now you had a canvas and thenyou had the ibm class libraries and youyou dumped some of this comprehense onthis contrast you connect themtogether with some operation and thenpress generate and thenthe program would be generatedandone interesting aspect about visual 8 isalso that it's actuallya kind of root of what eclipse hasbecomeoki click on man and fish i do a minimizeand i do maximizeand i'm there okaynow one thing i i have with uhcoding especially if you're workingtogether or if you are working onmultiple projectsthen you always comeacross some structures or orother our clothingstuffthat you use cut and paste in youreditor where you need it and thenat some timeyou you have quite a confused state ofeverythingsothis is why generationis an interesting aspect because itcomes from a single point of originnow when one could[Music]use this thiseditor cut and paste forcreating spec files for which to buildrpm packagesor one could think how are these textfiles builtwhat categories do i have and how can iput this in some kind ofmodel and some kind of enginewhereone who iscapable ofsearching for batteries using some otherclassification feeding them to thisengineand then deleting the packagessoget another fish and he has food for aday and learn him to fish and he hasfood for lifesothe underlying idea about thisis modern engine and about the modelingof an engineering for ours tooyou want me to go to the next oneoh yeah well i will do it because if iminimize and maximize it seems to workokay okayokay so now i may be using someexpensive termsbut what isprovisioningpositioning means supplying it is tosupply somethingso software provisioning is theprovisioning the supply of softwareif you think about your internetprovider thenthat one provides you supplies you witha connection to the internetyour presentation is about providingusers of those two with packagedsoftwarebut more precisely it is about theprocesses involvedand what i mean by there is actuallymore about umthis idea of this man fishing and tosupply this engine and supply awhich makes it much more easy forpeople tojoin in packaging without having to knowall the drawing details about how rpmbuild works or other tools andsettings and naming and other coreventions which we do needbecause without conventions you cannothave acommunicationwhichwhich you cannot collect componentsso this positioning is not aboutthe dumping of one timepackage temp which would be manuallycreatedmake available because the questionadviseswho is going to maintain it's going tobe a headache and how can we thenpackageadditional softwarewe need to have package and haveavailableso the whole idea is to have some kindof enginethat uses this modelingconceptwhich makes it easy for people to joinand have their skills and not bebothered with detailsnowbefore igo further in this positioningstuffi have to do a little bit of reflectionand that isis it not is it not refreshingand then this onesodon't be offended i called it the goosethe bad and the uglydudesthe usb 3upcoming divers and the nvme driverswill enable the use of more modernhardwarethis is of course very important foralways to remain fireballwell what bitbus buzzworks has beendoingwith with making the unix live user landand the porting of qpis a very very importantworks because it opens the doors forfuture developments on hours tooand toexpand in this direction wherewe can use unix-likesoftware and software from unixand that coupled to the model-drivenengineering can make itmore easy for people to contributein their test actwellthe eurasia developments of course areare very important because these allowus too to be installed on non-buildmachines bios machineswhichwhich willi don't know what the state is at thistimebutonce that failure say that the buyerswill of course grow extinctand the gpt developmentwill allow us to be installed alongother operating systemswithout[Music]thethe master boot record constraintswell the upcoming chromium-basedboundary is also of course from fromvery important so so userscan still browse the internet which isnow going to html5 and uses a lot ofstuff that other browsers just don'tsupport or have or do a very correctlyrendering on so these are very importantaccomplishmentsat the stage with where we are nowalreadywell there's also badunfortunatelythat we are a small communityand that knowledge of about our systemis fadingandwe let a morgan gui or web-baseddevelopment toolssothat makes attracting new developerswhich i may be dreaming but i think itcould be possible because wellwhy is there badly people trying tomount everest well just because it'sthereben then can cancan i make a small addition hereyeah one of the things that people mightunderstand that a bit better is asksomebody to write for example aworkplace shell class there are very fewpeople that are able to do that or writecode to write a pm programi think i'm just givinga hands-onexample i think that we've discussed inthe past where you think that that'swhat you are referring to with a fadingknowledge on how to write such programsyes well it's not just a fade inknobbits it's it's also the incredibleamount of red tapeyou have to first type inbefore youactuallyhave something running yesand if we if we look at some class-basedthing likethe system object model or the workplaceshellthen what actually needs to beimplemented are a few methodsand and the rest of the code is allboilerplate cardsso if we could generate that from amodeland then just have somebody focus onwhat needs to be implementedhe could attract a new generation ofdevelopers which are uhmore selfie-like like i can do thatbecause they are just focused on that onthat part and don't have to knowthe whole uh c ban that's that'sunderneath it and all the ins and outsof ours too yes for instance if you ifyou just have some code to uhcreate a pm presentation manager windowand you you justuse the normal parameters then it'shiddenanda new generation want to have it visibledirectly and they maximize so all thatkind of stuff is what you would put inthe model by using same defaults but iwill address that laterso these these are are needed uh theyneed to be addressed for hours too toretain any kind of future relevance andwhat i mean by that is thatespecially on the development frontand going tomovie-like ofthebase development tools and probably alsoweb and then focusedfocused viewwe might attract some new people justbecausethey are interested in doing thatbecause it's an uma challengea challenge for themand much of the new generation likesthese challengessolet's have a look another italy i willdo that very fast becauseit's there butwe know itours2 has a heavy 16-bit legacy memorymap device drivers cah addressingandlvm is alsoin the wayfor somethings we actually would want with thesystem under the hoodthe usage of rim 2 was a major hurdlewhich has nowbeen taken away and that opensinteresting roadson the virtualization front of ourstream so while these are not showstoppers they certainly do not makethings more easyandwe will see how that all pans outum[Music]i have to lookexcuse me for some time minimizing butumokayuh software makes the machine withoutsoftware where all the desktop knowwhere to gothis is why the rpm packaging system isvery importantand it's important that we canpackage everything that we want tostarting withexisting legacy softwarewhat we need to do is toidentify which legacy software is ofinterest to be packagedand for that we can do a classificationbecauseif you havesomepackagesthat are alikefor instance inwhat kind of this layout they have umfunctionality and whateverthensome template can be made for thegeneration of the spec fileand the spec file is actually the makefile for an rpm packagewell if sources are available that wecan also define build scenariosdefine packaging scenarios in case thereare dependencies and whatever and allthis stuff can go in such a modeland such a model can be processed i willshowsome slides about that laternow packaging legacy software is usuallya one-time actionbecause there is no developmentmore and more on such legacy softwarebut some of that is quiteuseful it's quite niceandwhat we actually also want is when wehave some kind of template to generate aspec file for some kind of legacypackageand we find other packages other binarypackages that are kind of like thatit's easy to add them to the engine sothe rpm packages can be generated forthemso classification enables[Music]automation well we can safely say thatdeveloping native software for hours touh forfor common useis is not the way to go especiallywith withthe thenext basedevelopment environment we have nowwhich of course is required and quitenicebecause we can use already existingstuffsoin this environment usually the sourcesare availablewe want to follow upstream developmentsand integrate these upstreamdevelopments with minimal effortand also of course to do compatibilitytesting because in theunits world slashes are used and columnsas separators which need to be convertedtobackslashes and semicolons and there areother issuesthat will need sometweakingto have mixed software run on hours tooautomation complements our scarceresources so the more we can do withautomation anda modelling engine whichgenerates somesources andsomebody who wants to contribute canjust focus on gettingthings done and not being bothered bythe whole class here he or whateverdetailssimply simply makes more time availablefor really doing the work instead ofbeing bothered with withcut and paste in the editor orwith red tape of border plate codewell newly developed softwareof course we have somethings wewe might want to developone examplecould besomesomeprocess thatmanagesdemonswhere you caneasily start or stop backgroundprocesses enumerate them anddo other stuff with themthat of courseshould that that of course would be madefrom scratch because it's highly tighthighly coupled to the system itselfandhere also comes the idea around thecorner of using a model where you firstactually define what you want in somevisual formwhere thenthe baseline of the code is generatedand the functionality can later beimplemented well if you look atpresentation managerforgraphicalpoints of the interfacewe can safely saythat at this time at this point of timebuilding something like that fromscratch by for instancea new developeris much too complexit's even too complex for for veteransbecause you have to do all this updateunless youcopy paste some stuff you already havenow the qt very verboffers very solid alternative and ofcourse there are already very muchvisual toolsrefugee designer and other stuffthatalso is in the realm whereone can define things in a visual wayand where coder can be generated andlaterthe functionalitythe focus can lay on the functionalitysothis coupled with some model drivenengineering which is at a higher levelatthe models one can defineand selectwhat kind ofscenarios is needed and what kind of ofblueprintis needed and then generate this thisthe source codewhich canbe compilesandbuilt intoexecutable programs librariesdocumentation and other stuffnow can we improvethingsand that is actually by i think byenhancing development toolsnobody is goingexcept the settlements you are going totake make at the common timeto see what kind of targets there areandit's also very difficult forpeople which are not directlydevelopers but still have skill setsto join in some kind of collaborationso leveraging individual skill sets ofpeopleand then taking all the details anddifficult stuff out of the wayis i thinka methodwhere we can improve thisbroader and selective cooperation iswhat i what i meanpeoplehave skill setsand let's say that two peopleare interested have an idea tocontribute to some kind of component wewant to havethat is selective i mean so they areselectivelyworking in this kind of component andonly i have to focus on itsfunctionality and the rest of the of theboilerplate is generated and kind of anenvironmentthat is automatically generated by sucha modelas far as developmentmeans that the first thing outlinesoyou have a model and for instancelet's let's take a mind padwhere youfictionally specify by means of topicsand relationswhatwhat you want how this functionsand thenyou can already actually generate anexecutable it just doesn't have nothingit's always a kind of a mock-upbut it already does somethingandtheimplementation of the functionality canbe gradualand that is kind ofcomplement focused worksoyou actually focus on some kind ofcomponentandexactly that component is where thefunctionality is which is part of alarger hole and the larger the largerhole the larger picture you don't haveto worry aboutand then what i earlier said aboutconnecting the end window where it doesnot show if youdon't tweak the parameterssoto have certain defaults and same andsame expectationsimportant aspect of a model-drivenengineeringbecauseif you collect two of those componentsusingwithsome function in it you expect thatyou have some expectation about how thisoutage would work and that should bein indeed the way it would workokay sothat is a bit aboutthe reflectionof where we are and how we might be ableto improve thingshello[Applause]so at first we are working on threerealms and the realm is actually a kindofdomain and these three domains areengineering collaboration andpositioningandthis is part of engineering which iswhich i i have to cover because theprovisioning is actually builton the concepts of engineering andcollaborationso this one is about making developmentfor os2 more accessible in various waysit does this by harnessing tools andtame them for easier use so this has todo with thesame default and like that it behaveslike you think it is but moreimportantly actuallyhiding them at dashboards which i willlater explainconceptually this realm is aboutprofiling ways and meansto produce products and byproductsbullets you can think rpm packagessoftwareso one could say this dom is kind oflike a factory plantso it is thecorestuffwhichwhich is one big toolbox and andbuilding enginei wonder if this also would workit doesn'tokayi think we crashedoh yeah that's right yeah i'm startinghereokay it crashes everything if you'rewondering why i'm minimizing andmaximizing it's becausemy feelings it does not update thatnightsocollaborationup like thisokaywellthis realm is about improving workingtogether to reach common goalsit does this by putting the participantin the centerwhich means that instead of somebodyhaving to learn all kinds of tools andbackground information and web tapeeverybody has a skill setand the skill set is the focus pointso it's determined it also determinesthe interface through the toolsandif you are in some kind of areafor instance you are capable of doingsome xslt transformationthen then this this is skill set andthenthe interface to the systemwill specifically have that as a focusso this enables a participant tofocus on thearea of expertise and leave the vectortape handle into the factoryall the stuff you don't want to knowand the goal is to enable constructionfrom partswhere uh imaginemore participants are are working atsome components in a broaderbroader picturethen uhbyby focusing on the skill setand umviewing things as a as collectible partthis eases collaboration and we don'thave tofind outwheels again and againso the objective is tofind is toprovide the shortest means to get froman idea to a resultand it's alsocouples the last onetouh just the sparse development traitwhere you first do the outline so you'llhave an idea it has an outline and thenusing this model-driven engineer you canactually already create an executablebecause the outline is all generated foryouof course it does nothing and there hasto besome more stuff butthe idea is to havesomethingworkingas fast as possiblenowthe provisioning realm is aboutproviding software in packaged formas i said earliersoftware makes the machine withoutsoftware road desktop and nowhere to goand there's an enormous amount ofalready existing software that can bepackagedthere isof course in the mix programat the source code level an enormousamount of softwareand what we actually want is to make iteasy tointegratethat stuff and feed that to some kind ofprovisioning enginewhich then generates the rpm packageswithout having to bother how some toolsworksonew packages will emerge and the shiftpackages will be updated so this is aprocessthere is an iterationand one can imagine that professioninghighly depends on collaboration andthe engineering grounds so the engineerwho now provides the toolsandharnesses these tools and takes out therough edges andmakes them work together to accomplishmore purpose tasksand collaboration ishow people work together to easilyexchange the thingsand or ideas they haveso the goal is to have an elaborateamount of installable software practicedusing standards with low maintenance andthat can has a high degree ofmaintainabilityso we don't have to spend uhmuch time at uh things with upstreamchanges or other changes on therebecause we can make that change in thein the engine and then thisautomaticallypropagates to the resultsso from a user point of viewone could view positioningas a shopping window it's where theresults layfromeffortsof ideas packagingsoftware developmentwhatever ultimately a productwill be an installable packagenow i said earlier model 11 engineeringmodel driven engineering isthe methodandnow i have it openi thinkit's openso at the highest level a mobileprocessor is nothing else thanfor instance somelike bluemake or some other build toolbut instead of playing text files it itaccepts uhwell let me rephrase that it's actuallyso it's a black boxit has an input it has a it has acontrol on how to process that input andit generates outputand then if we look at some moredetailsthen we can see that at the left inputwe can have freeform models that are isactually um your ideaswhich you first drafted in some kind ofmind mapper or or made them visual sothey are our first draftcode can be generated from that but morespecific stuffneeds to be done with other kinds ofmodelsand those are the formal modelswhere e-coreis the coremodeling system of eclipse it's whateclipse also usesandthat model describes data types classesand interfacesso for instancesome kind of workplace shell classextensionwould be expressed in an e-core modelandi actuallyhavegenerated from the from thew from the workplace shellusing the someinterfaceumthe the interfaces which and thengenerate and then convert them to ane-commerceall the classes and the hierarchy of theworkplace shelland data types anduse thatto generate a codenow another model type is the own modeland that is actually what eclipse usesuh for itself tocreate release trainsfor for anybody familiar with eclipse asi said also earlier that actuallythe core isjust a runtimeand everything else are plugged inand how these pluginswhich pluginsare combined together those make up arelease train like for instance eclipse4c plus pluseclipse for mobiling eclipse forfor phpwhich is actually a collection ofplugins whichtogetherprovidesomerelated functionalityand that is expressed in oomph modelsandeclipse is if if if you are familiarthen nowadays you cango to an eclipse site and specifywhich things you want to have and have acustomrelease train of or custom compositionbuild for youwell what that actually deals with atsome level is projects and productsand projects you can envision asbeingpointers to source repositories likegitship projects their interrelationssettings and whateverand products are installationslike for instance eclipse but in installeclipse you have this specificinstallation configuration and you haveone or more workspacesand this installation configuration isactuallythe thing that builds that particularconfiguration of eclipsewhich would be expressed inin the projects parts of this type ofmodelnow this model also maps quite good atrpm packagingbecausethe whole is a project in the sense ofthatspec files are needed and other settingsandwhat kind of workplace shellobjects need to be generated foldersicons settingsor whateverand the product itself which is actually[Music]the rpm packageand there you can have severalversions of a package with severaldependenciesso in the products part you canenvision as beingthe sourcepart of the whole and the product partyou can think of as as the as buildpart wherewe talk in products and versions anddependenciesand then outputcan be properties build files moodleinstances which i won't want to go intotoo far but the idea is thatlike with a black boxyou can cascade them where the output ofone black box is the input for anotherblack boxand if you are a little bit familiarwiththings like xslt and trump such xmltransformsor general piping of toolsthen you can understand that if you haveseveralmobile processors in sequence that theybuilt some kind of scenario to come fromsomethings defined in modelsat the most leftlevelwhich then[Music]ultimately propagate to the productlet's see so on rpm pick a package orsomething else a program executablelibrarydocumentyou name ituhnow the whole thing is is based on theeclipse modeling frameworkand[Music]the core of that is ecore and what ecoin essence is isaself-describingclass hereand it'sencompasses data types classes andinterfacesand at that levelyou can already understand that manythat it can generatesources for many object-orientedlanguagesor even non-object-oriented if you wanttosofor instanceif i would define classes in an e-coremodeland then i could generate from the samemobile i could generatecps dress codei could generate rex code i couldgenerate javascript i can generate phpjava itselfand actuallythe sources for this site arebased on on thissimple form on based on this conceptnow as i told earlier the home model hasto do withprojects and productsand in a sense this has to do with ifyou have an ideathen you do a first scratch and a mindmapthen you actually get more formal thenyou get projects where you handle sourcecode in this focused mannerand at the other side you have productswhichrepresent rpm packages which canbeput in repositories and made availablefor people to installon the os2 systemuml stands for unified modeling languageit is much like e but much more detailedandit can be used if things cannot beeasily expressed in e-commerceall these models themselves areexpressed in xmland xml is an interestingformat because it is self-describing andit also actuallykind of functions as a databasethis is because all the elementsyou can enumerate them you can give themidsandthen search an xml file and just extractthat element and process itnow this is why this eclipse stuffit is possible to use on ios2 becauseall these models are xml and of thesethose two is perfectly capablethanks to all the reports bitwiseworkshas done of the nyx softwareto to process these models and togenerate a source code which can then bebuilt on those two itselfsowe actually don't directly just needeclipse we just need its modelsthese these models can be extracted fromfrom get repositories and andotherplacesthe main importance is that they're allxml they're all text basedandthey contain many value many valuablethings we can use on our posts tooto[Music]to compose these models we need toeasily create softwareand port softwarewellone interesting thing is that suchmodels can also be referenced using urlssosomething like we get a specific modelcan get this model and then it can beput to the processor the model processorand then all the border plate sourcescome out of there and you can do a buildand you have a first mockup that's theideaso fsltplays a big role in thisin this conceptandmodels areare actually just like blueprints likelike if you're going to build a houseyou have a foundationand that's the whole engineering partand then you have a blueprint is how youwant to buildthe housewith the windows the door themeasurementsrooms and whatever and that's what youfeed to uh to some kind of engine andthere are also engineers on the sidewhich are the collaborators which cantalk to each other which models you usehow you collect partsandwhat you want as an end resultnow modern driven engineeringfor hours toois a broad term for what i'm working onin this in thisconceptanditis course uses the eclipse modelingframeworklike i explained abovemodels are externalfilesand sowhat we actually do isplug our eclipse for everything usableandthenyou do that on oauth2using a modelprocessorben soben can i ask you a question yes are youclose touhto finishing your presentationare you close to okayyeah well i can skip thisif it's notif it goes in too much detailsand go to the positioningokayyou're nowusually we try to keep presentationslimited to 45 minutes and you'recertainly not the first your firstyou're certainly not the first and lastperson in warp stock history to go overthe time slot of 45 minutesuh so but you're now in 50 minutes so ifyou could uh wrap it up and then we cansee if there are still questions fromother peopleyeah of course i was i honestly i didnot keep track of time and i i thought iwouldthere would be a bunch of timeleftso i maybe have come into too muchdetail buti just wanted to coversome of the underlying stuff becauseit's actually thebasis of thesoftware provisioning which is theactual the actualsubject of the specificationso i'll go last this presentation isonline so you can you can keep viewingit you can view it afterwards orwhateverumproviding a means ohalready was there that that was thefirst one umaheadso we will go to the big picture andthis is thenhowthis model driven engineering stuffkind of umwould look like visuallyso under the hood we have not writtenengineering for os2 with its modelsgenerators engines development toolswhateverand so a provisioning engine would besome kind of derivative of this modelthis core engineand thentheproviding this iterative process and nowwe have to go counterclockwise that wehave the internet there is much legacysoftware of ours2 available our sourcesare available on github and other andnetlabs of coursesource repositories imageswhich can be processed using image magicother resources whateverand thatcan be gatheredthen we have the classifier whichclassifies this stuff because what weactually want is a template where we canprocess that can be used to processlook-alike things we grab from theinternet so you can see this as somekind of octopus which has his tentacleson the internet and then gathers stuffwe can use and where we can buildpackages forthen we go to the packager and thepackager usesthis enginewhich is based on this modeling conceptand then in the final stage is where wehave a publisherwhich thengets this packages and after testing andsome other stuff it can it it willpublish these in therpm repositories which canwhich are then available formachines that have the urls linked sothey appear inthe package manager and are usable by uhyumnow from a packager point of viewsoassuming uhsomehands will at some time uh write say heyi would like to to help in that stuffthat you are a publisher and then youget some kind of dashboard and thisdashboard represents the actions neededto accomplish this taskthe range of workspace and then underthe route there is the positioningengine which takes care forthe gatheringand building like explainedabovedashboards are an important conceptof this model driven engineering becausedashboards provide the action interfacesthey can be as simple as menu driveninterface or a dialog box with controlsor a more elaborate notebookdashboards map the high level actionsonto mobile driven engineering for hourstoo actually it maps the skill set ofsomebody who is helping to theunderlying toolsto make things as easy as possiblenow file commander is a good example ofa tool that can present a menu structureso here you have an idea of what can befaced withif you were somebody helping in doingthis and then focusing on the tough sowe we havesome kind of new structure here and thisstructure is also expressed in a modeland this model this is definition in themodel is just generic so it can alsogenerate menus for the workplace shellfor vm application or for[Music]umfor for even even a work a shellinterface like thingnow a notebook of courseis more nice because then wecan have googie like thingsmy excuses that i puta taxnotebook in here and not a pm notebookbut i had notime to to have to just i did not decideuhto view this until it was later sodon't worry such such thing you canimagine thata pm notebooklooks similar like this can look similarlike thisand all thisthis complete layout is generated from amodel where it is expressed andin this model the module editorcan[Music]move things around and then generatea new version ofsucha dashboardnow we go toyeah okayokaywell okay the last part is if yenvariant epf epm is a very powerfuleditorusingmodels we can create rect sources so itcan serve as an ide integrateddevelopment environmentandvariants addresscertain perspectivesperspectives like you guessed itpackagingsuch variants will become available asrpm packages so an rpmvariant can be seen asa some kind of super dashboardand hereyou can seea simplesimplevery very preliminary screenshot of anepm demovariantokaysimilarly this is the last lastattemptsosoftware provisioning is an iterativeprocess we are trying to automate asmuch as possible and by we i mean whatwe are doing here at voiceand we want to develop high level actioninterfaces for anyone willing to joindoes not have to learn rpm build orother toolstime will tell how this all works outlet's leveragehours toothen i go to my last buttonwillso thank you very much for yourattentionandhave a nice daythank you for your presentation benuh i'm sorry that i'm sorry i had tobreak into your presentation but we'vegot a 45 minute time slotas you can seeuh there are ideas in the communityumandben is basically asking you for helpin the past i've explained to you thatben was working on rpms to be built ithink i needed to make us justif as acorrection therehis idea is to build rpm files withthis modeling engine to have consistencyin building them but this whole projectgoes way beyond that butthis is one of the objectives that ithas to reach but it is also intended totry and make development easier as a lotof younger people are not familiar withhow o2 development works sothat was a kind of a dive intoeverythingum ben thank you we will talk anothertime again privatelyyou can you can click on the hang upbutton thenum i'd like to thank everybody for uhfor uh tuning in to warp stock and nowthat everybody is awake in the unitedstates could you play the video from newwall tower there's a request for warpstock usuh from new wall tower andhe has sent in a recorded video and thatwill be played right nowhi neil waldhauer here i serve as thesecretary of the borpstock board ofdirectorswe are seeking someone to help usproduce an online version of ourconference warp stock corporation is anot-for-profit organization ofvolunteers dedicated to promotingeducation information and socialopportunities to those personsinterested in computer operating systemsand related software through productionof at least an annual technologyconferencewhat this really means is that we have asmall core group of people working tomaintain public awareness of computeroperating systems outside the mainstreamhelping to ensure that they know aboutthe choices they have in personalcomputing todaythe warp stock conference has beenmeeting every year since 1997.there was no meeting in 2020 due to thevandemkwe ran an online event that was in ouropinion less than satisfactory for ourparticipantsthis year the warp stock conference willbe an online event againwe miss having an in-person event and wehope to be able to hold one in thefuturein the interim it is our goal to providea valuable experience for our virtualattendeeswhile our statement of purposes forcomputer education we specialize in thetechnology of ibm os2 warp operatingsystem and also in arca os a currentoperating system based on ibm os2technology we are interested both in thehistory of os2and in the current development of arc oson current pc hardwarefor that reason we are seeking a personor persons to join us in producing anexcellent online conference specializingin os2 and arca oswe already have presenters but we lackthe ability to give a truly engagingonline conference we are trying to servea group of generally mature computerpioneers from retired i.t professionalsto still enthusiastic home usersif you are a user of os2 looking toengage with the existing community thatwould be a big pluswhat we need is someone with theexperience personality and skill to keepour presentation agenda going and ouraudience engagedthanks from the warpstock board ofdirectors for watching our videocontact us by email at presenterswarpstock.org if you think you can helpus make this year's warp stock a successwellas the saying goes that's all folks umare there any questions beforeisay goodbye to you all and hopefully seeyou in another warp stock i'm lookingum[Music]yeah okay i already see here that uh mrfaulty is umis making uh is giving a wave ofapplause for uhuh for me and in the background uhyou're ruined for making warp stockeurope happenit's just a two-man show we've preparedthis probably in the last weeki've been very busy with my day job soit was about oneam in the nightand we finished some last work montagein the last couple of hoursbut here you have another warp stockeurope i think we can safely say thatos2 is still alive and well it has morelights than a catand with the upcoming technology comingfromarkanoa and bitwise worksyes everybody say yesos2 could have been dead tomorrow it canbe dead in five years but if everybodykeeps saying that it's dead it willprobably still be alive in anothercouple of years sothank you for your timei see no furtherquestions popping upthis video stream will be publishedonline for people to view it outside ofuh this presentation scheduleuhhope that everybody stays healthy thatcovet can go over and that we can seeeach other probably somewhere in may infrankfurt for realit's now 22 15 here in the netherlandsthis is nike netherlands signing offthank you for watching and see youonline or in the forumsenjoy your weekendsyou
