 we will stop now hello welcome so the introduction seems to be German so I will translate into English of course hello welcome to the lightning talks there are still open spots so in the wiki there's the gratitude exchange and you can write in whatever you're grateful for and that will be read out later other than that the speakers will just be without sound so they'll be muted and without picture as long as it's not their turn and looking forward to the talks and there is a question pad of course linked in the wiki looking forward to the talks and hopefully you do as well we'll start with Moritz and the chaos sticker collection hello Moritz hello Ben hopefully you can hear me I'm just sharing my slides so are the slides visible no slides yet yes there they are now we can see them hi I am Moritz I want to talk to you about a small project of mine and it seems like we lost connection there so due to technical difficulties apparently a bad internet connection I would suggest that we just skip to the next talk Moritz reboots his connection and we try again afterwards so that would be teased with copycoil and pop culture so hello I want to talk to two problems from the perspective of musicians where I see need to find appropriate solutions and I am looking for people helping me developing those solutions so I would like allies and again we are fighting with my technical difficulties yeah okay we had to end this creature there can you see me now yes now we can see you should I start again okay let's start again so today I want to I would like to talk about two problem areas from the perspective of musicians and I am looking for solutions that are appropriate for the digital area era and I'm looking for allies the one problem area that I can see at least is copyright and during the 20th century it developed sorry I didn't quite get that but it developed badly I would assume to insert little bit I want to talk about the history during that happens during the 20th century up until 1920s music was hardly protected but that changed with the industrial revolution and when it was possible to use machines to distribute both the notes and the papers and printing but also automated pianos and during the first three decades of the 20th century up until the 1960s the runtimes for musical properties were rather short and you had to register for your work to be protected and after that it was fully available and also if nobody registered it it was freely available from the 70s in most industrial nations there are there are slightly differing rules between the countries but it's mostly around 70 years after the death of the author and that is quite a long time so the author can use their work as they see fit until their death and also those who inherit those rights should profit from it but after that I think it's quite problematic and of course the distributors and those who use those rights who are not composers or artists themselves they profit largely and of course we could shorten the times but maybe that's not even the most difficult part of it before the digitization a lot of things were forgotten and music got lost and of course there was new music that got influenced and back then it was normal nobody knew where some idea came from and what belonged to who and what could be copyrighted or what could be in the public domain because people forgot about things today it's quite different everything is available and everything is present for people and at the same time as much music as never before is created which is good but with the run times of the copyright everything that is possible everything imaginable will at some point be copyrighted technically that's already the case there is a lawyer and musician who 2020 went ahead and just created algorithmically everything that you could imagine and there's also a TED talk about this and I will post a link to this in the pet and since then technically everything that you can imagine is copyrighted the second area I want to talk about it about is the practice of streaming so 90% of money made is made by streaming most platforms use a rate system so everything is collected and depending on how many streams in total you had you will earn a lot and who already earns a lot gets more and who is listened to the least gets less that's similar to the when you are at the music shop and your the price is depending on how often something was bought well not the price per se but how much money the artist gets so it could be different it could depend on how much the listener is really listening to if I am only listening to one artist then this artist gets all my money for the month but of course there are shareholder interests that are against this and there are four big multimedia companies who really have other interests as well and big lobby alliances who have interests and that circles back to copyright and they try to keep this running the system and a lot of things that are established already they try to give them further reach there is political will for reform and in britain there is parliamentary action happening but of course the politicians don't really know what they're talking about so it's troublesome my question for the community what are your ideas to handle this would it be possible to have different platforms to develop platforms yourselves or ourselves that are more fair and how could an open source principle for this look like well would like to participate in thinking about this can feel free to contact me and that's basically it thank you great perhaps you also want to write into the pet all the wiki how you can be reached if people want to contact you yes and also put your link in there great the pet is also linked in the wiki where you can ask questions i see no questions in the pet so let's continue with the next talk search engine archaeology hello welcome to my presentation i hope you can hear me i'll show my screen so we will talk about the archaeology of search engine about me it's a small hobby you can reach me with this email address and i'm member of a of the real realm hackerspace so first of all there are two words search machine archaeology a search mention is a program used to find documents on a computer or a computer network documents are general it's not only about html but we want to find documents overall the question is how can we find documents for example we are looking for a fish that's not and it's north in the uk and here there should be a qr code here is the qr code anyways it should be in the slides you can find it later and we formulate a search and the first is fish the quote mean that it's it's exactly the word and then we search for the northern you those quotes are very important because otherwise northern europe and southern uk would also match and northern uk or scottish and we might either use the pipe or the ore and races like in mathematics and then we say we don't want salmon in this case we use the minus and it's commonly used to reduce word press and or perhaps you have an annoying search result you want to remove and then we say we want to use wikipedia if you search it you will not find northern fish but musician who is shot scotch because only because you are able to write a good search query does not mean you will find a good result so let's continue to archaeology the english wikipedia says it's the study of human activity through the recovery and analysis of material culture it's not about the analysis but it's finding the document items search management archaeology is if we use search engine to find digital culture a well-known example is minecraft and perhaps you have run minecraft or played minecraft you could write that into the irc and a minecraft server has document config files white lists band players and operators and that knowledge can be used to search for minecraft servers we can go to google and then find minecraft and we are looking for op.txt or jason and we require the the title that there is index of that way we find auto indexes and now we have a list of minecraft servers that are publicly available and now we could go here and download the world and perhaps look at player data where are the enemies which equipment is used or we download the map and play there because it's fun and that way we can find a number of different things and the large limit is the own creativity rather than the search engine thank you there are questions is there just one search engine or multiple sometimes it works in others it works best with google but yeah i tried to search with different search engines but i got significantly worse results which is quite sad yeah what's about search engine outside of google thank you very much for your talk and you left contact data if people want to have further information they can contact you and i'll also write them into the pad thank you all right then the next talk is licensed by betalars hi i'm betalars um i would like to talk about in this leg talk of collector and about that licenses are no use to anyone so we have a legal situation where everything that is artistically created is something that in theory only i am allowed to use and only i and my ears are allowed to use it because the copyright protection lasts until a point much after i have stopped existing in this universe and that i just find completely inappropriate in the general sense already and we urgently need a reform there that somehow reflects what we have in pop culture and in meme culture and does that justice because the way it's implemented at the moment well i as a small creator will not be able to enforce it anyway um and that is only of help to monopolies that have the might to push through regulations that even or copyright for projects that even in the american sphere would be classified as fair use um but what many people don't realize is that creative commons has its problems too creative problems has many different licenses where i can state in what way i allow my works to be used i can use cc0 which is close to public domain in the us sense and i can stipulate that people tell that i was the creator i can stipulate that it should not be commercial and and many people forget uh that if they use a work they should link to the license as well that is part of the conditions too what i also find disturbing is that i can't say in creative commons yes you may use it but you have to be excellent somehow i want my works to be used so i cannot say that you have to be excellent but i don't want my works to be used in political ways that i don't agree with and there is no really good free license for that and thinking of new licenses is not a good idea either but the most brazen thing that really gets my backup is trademarks i can't i'm not allowed to write a story about little prince although the little prince has entered the public domain a few years ago the issue is trademark so after copyright has expired works can still be protected by trademark rights and then become effectively unusable and that's just an incredible offense i have no good way of solving that and i just wanted to vent about that and create some awareness of that thank you yeah thank you for the rant there were no questions about that but maybe you can enter into the pad how to reach you how you can be reached and maybe you can get together yeah i'm happy to do that although i have to deal with real life recordings right now you can reach me under mastodon at ks.show social just ping battle us thank you very much next there is mic with cellmate sorry yeah i can tell something about cellmate cellmate is a small project i started last year and i just want to tell a little bit about it so what is it it is a iot bsm gadget and the combination is weird already it comes from china the user so it's more a gadget in the toy so the top can decide on things and the bottom or the sub what they can or cannot do and without violence you cannot escape it the infrastructure and i was looking at the app mostly on iphone and there is an api and that's on a very old apache tomcat the mysql server is reachable from the outside i we found an admin interface it needed a login but what i was using via the api was completely open and you didn't need anything to do something and it was just as bad was the api that the app is using and we'll have a look at this in a more close look so after logging in you got a member code that's just your next timestamps up to the millisecond from your registration but there was no token for authorization and to interact with other members you needed their member code so when you were logged in and looked at your friend you could also interact in their name so the localization was another bad point we could see who everyone who was using the app is living we had i think the top 1000 from the system so it has 15 to 20 000 users and we had quite a high definition for where the people are and we could also look for in what area they are and how much are they moving i don't know we could it definitely search one area so get all the users in a certain area and this was also collected if the user disagreed on data collection one of the worst mistakes was the password it was collected in clear text it was mostly returned only encrypted but in two endpoints it was even returned in clear text so i could check the passwords from other people i was getting passwords i was getting email addresses i was getting everything and they did everything wrong they could have done wrong and after contacting them for the first time they removed it from one of the endpoints but the other one still provided it so on the 17th of may we worked together with internet of dong the producers of the sex toy and we were talking to them emails but then there was nothing then in june they closed the api but on twitter we by accident noticed that other pentases are also on this so in september we were coordinating with those and in october we were publishing our research i am linking it in the in the pad because it's very interesting to read and in the end it really got published in the bbc even so bbc the guardian hi the cnn a lot of big media and people really noticed this and then blackheads got onto on the case and started attacking people and only then did the producer react when the holder function deactivated i feel a colleague attack uses that got under attack and deactivated the holder function so everyone can open the cage and now there is a new app and it actually was pen tested properly and that's basically it yeah thank you very much very nice do you maybe want to link to your blog entry as well yes i will create other than that there are no new questions thank you very much now we have a special honor i'm allowed to read the great community others people thought about this but i was asked to read them and now i read them i'm grateful that linda from brain feudal created a great merge and we had so little work thank you linda i thank bindi i mean for the creating of the pets of for the organization thank you i thank pq for the great museum tour i'm grateful that there are these great bull that give up their free time to create this great event the walk i know who you are and you know and i know what you do i'm thank you for f and other for who prepared the video streaming and put a lot of work into it i'm grateful for the accent who who helped this event to ensure that more people are feeling welcome i'm thank grateful for the awareness team that create makes great work and so far i never had to contact them i'm grateful for s to be who did a lot of work for nearly everything on the event and how much time he spent to make ensure that everything is helpful i'm grateful for mr capture to create that many meeting places in the wiki thank you for emilia who found the code names game and participate at the beatbox workshop that's sorry for mispronunciation of names thank you for the large amount of talks in the main program and i got in touch with subjects i'm not interested i i never met before thank you very much for the hex and their inspiration and their queer program christina especially for the great talks thank you christina and julia thank you for santra and olia for the great heralding and i'm grateful for the cement and moderation for the rico talk and i did not figure it do not know who you were i like the names of the hex thank you for everybody who created these great maps thank you for stopping for the easter eggs thank you for the world thank you for the far plan thank you for the people who welcomed me in every session thank you for the cure for the integrative actions dear community despite us all being so tired it worked again this small thank you for all those who created all the small small items that made the world unique for the community thank you kuchen thank you hasen thank you everybody thank you to the community who all are part of those who create a contra image to the world outside where so much goes wrong we hope that we can take the energy we experience here to update the world outside the community as a refuge but also as a place to get energy to move the world outside ahead thank you for the opportunities that to to move in unknown areas and learn from one another and this is to see there are so many inspirations sources that are visible in events like these thank you for titanum for all the small thousand small and large things thank you for all the beings who we don't notice but who fix all the small bugs here and there thank you everybody for the sessions and the relaxed acceptance of new people thank you for the hexen who announced all the program on mastodon thank you for everybody in the stream for watching without an interested audience everything would be quite boring thank you for the logo generator thank you for all the delivery item drivers who did not participate in the event but still gave us something delivered us something to eat thank you for this new event that brought us great time thank you for the obs introduction now i also have a flying rocket and the image and discovered a great new tool to work with next challenge the deep deck sub from backdoe and bambi for the next event works thanks for the team of c3 lingo to make this event available for foreigners thank you for everybody who participated and helped that this and future events exist so thank you for listening and hopefully for us is ready with his internet and can talk about the chaos ticket collection hello ben can you hear me i can hear you great okay i'm going to try now but i opened the trio talk now should i have that one now because i have the honor of giving two talks two lighting talks here i do too much so can you see my screen now can you see my slides yes i see your slide great okay i'll start then well welcome first of all i moritz and i have a small open source story to tell which is called trigger you can see with these locks i kind of signify what i'm going to talk about it's not cellmate but something different um it started with open lab in augsburg which is a hacker space a hack space that i like a lot and we had an app there to open doors such as many other hackspaces have an android app with a big button that you can click on and then a link was simply accessed using a token and in the meantime i moved away i'm in berlin right now and i i use a co-working space there a lot there are three physical locks through keys i'm sorry and replicating those keys for everyone that comes and goes is quite an effort people things get lost so it's not that simple so i thought hey we have this app and this door is linked to a rastery as well so something could be done here so i used the open lab app which was called swinger at the time and started tinkering around with it the first time ever that i did anything with apps and well as you can see in the screenshot it was a bit more than just a button that you can click on you can configure various doors here and you have various buttons such as a door bell and well feature wise the whole thing kind of exploded because it was fun and i didn't need to do support for calling a link in the background you can communicate via ssh as well and submit a preset command and then i thought okay well this kind of bluetooth thing i heard about that so let's put that one into an mqtt if you are into iot you know about that nuky smartlock that is a separate story and i published the app on fdroid so when that happened the thing was someone wrote me an email and said hey how about you supporting nuky smartlock and i said oh what's that and i looked and realized what is a commercial product an electronic lock that you can just mount onto the door lock around 200 euros i think but the protocol is open so corona started and i had some time left so i thought okay let's implement this too and the person that contacted me said well if you're interested in implementing this i'll just send you one a device via amazon so i received that package and thought cool a toy and went ahead and implemented it and it works so in general this is an app that you can use to communicate with various doors you can select whether a link should be called or ssh should be run or whatever you can see the status in the background here as you've seen in the slides before you can put in your own photos as well so feature wise there's quite a lot that is possible now qr code export import so you can pass on the key to another instance of trigger and you see that there are many many features ssh keys can be created htps certificates can be pinned downloaded our door system which ran on the raspberry pry had a nice htps certificate so browsers would consider it all but then the certificate expired and there was something wrong with the domain so we had to insert a feature that ignored the hostname check and the expiration date as well that check can be disabled not something you should normally do but it was necessary um so this app now exists and you can not just only not only get it on github you have the link to my project there but also on eftroid and i published it on google play if just to make that possible to certain people that cannot do with eftroid never heard about it don't want it so i published it on google play for a symbolic euro um i believe if people want to get this through google play there should suffer a bit as well right so that is my open source story uh this was about a year uh in the making including bug fixes so if you need something like this for your space or for other rooms maybe you can set up the pss in the server using a server some cgi scripts or maybe through ssh uh so trigger a door with a motor that way so for that kind of thing this app is intended so that's it that i wanted to talk about just to um spread the word and that got me into android programming and i learned something there and i'm happy if i hear that people use my work or even translate it i don't think i have any translations so far i'll have to check that so there is things to do still but it works right and that's it thank you great thank you there are no questions in the pad apart from the eftroid link oh the eftroid link yeah we'll just go to eftroid and eftroid org it's in the pad now all right thank you that is community work so will you continue with the chaos sticker collection yeah i can do that too so um let me just check how i can undo the sharing uh i think that was it and i'll just open my other slides now like this i can only see your old slide the change wasn't uh how do what is it how does it now yes wonderful all right so that didn't work so well in the first time the first item i tried so with corona people have too much time on their hands so this is another example of that and i believe that we all know that these sticker events feature many boxes full of stickers and you grab them all and put them up and then stick them and that's something i like to do is enjoy doing too but the problem of course is that these fantastic stickers then get lost and you then wonder well what to do now should i print them myself how do i get the files for that and what i did there was to search for people using search engines and i found a few links and then i thought well who's the author here could i ask these people maybe there are more stickers around from them and i did that and i wrote to people and that gave me a heap of sticker templates and i thought okay i wanted to share those as well and therefore i started a github repo put them all in there with a large virtual sticker box and i did a few things around that as well just to make these stickers findable so i attacked them i added information on the original authors what the license is most in most cases it's cc0 creative commons or creative commons something i think i'll switch to the next slide um it actually summarizes what i've told already so if you want these stickers you can copy all this as much as you want and you have can have a lot of fun there and hopefully in the next perhaps prevents a presence event you might be able to print some stickers yourself and and bring them and share them there and maybe change them around improve them somehow or as a favorite german word goes which is making worse in the process of improving so here is a picture of the repository you can show web pages you can include web pages there and using javascript i put something together here that makes you enter a word such as freifunk or chaos or google and you then get stickers for that so these are mostly sticker templates photos as well i think i thought i'd like but i wouldn't that i would like to have but it didn't find the originals fault and there is just a script that fills a jason file and you can um see it on the page there the project itself is on cc0 so you can do with that whatever you want and i think that summarizes quite neatly there are 400 stickers there which is good and it's nice to just try out the search a slot there and just have a rummage around browse it see some older stickers these are all previews but if you click on files you can go to a photo that and a directory that has all the templates in various formats that you may repurpose change colors or whatever and of course there's a lot to be done still first of all call to you if you have sticker originals or know anyone if you have bookmarks perhaps send them to me and i'll try to incorporate them just submit a merge request maybe copy it for your own purposes the licenses for the images in case you want to use them are mostly cc0 or creative commons but some have no license information because i don't know if you do know about a certain image please let me know so i can add the information and uh so this is a call to all of you and yeah more stickers please that would be great it would be great to surpass that 400 threshold i think i'm just below that right now so send me stuff have fun print just use it for something great thank you thank you the github repository has now been entered in the pad there are no further questions but regarding your earlier talk would you accept questions for that yes so what is that raspberry pi solution for a doll um well i think in my github repo for that trigger projects so github slash m warning slash trigger i think at the bottom there you have other projects that did something similar which covers the server side as well uh so you can find so i have you have lists for server side projects and click on that you may be inspired there there is some code that you could use to do it yourself or to install it yourself i don't know how well these are documented but that is a beginning and otherwise it's just a case of running writing this shell script to trigger a certain pin on your raspberry pi and that pin would then have to connect to the door mechanism it's as simple as that but of course you of course you have to set up the web server and um that is not something i looked into very deeply in my trigger project but if you have server configurations please do send me links there and i'll be happy to add the information so that people don't just get the app but also get some advice on setting up the server side yeah okay someone says nice project where is it being used well the thing is people don't actually tell me i they don't have to so i don't know where it's being used there are some stars on github that people have given me 50 or 60 so i suspect that it is being used i did hear from some people that they are using it but i haven't got the detailed feedback not a lot but it's nice to hear if people use it so again i'd be happy to just be given a hello we are using it in city xy or in this hack space uh that is the kind of love that you can give to developers to tell them thank you and your work is being used it works or just forking it merging requests if you find a typo somewhere um if you want to implement a certain feature for those that are more into android programming yeah so that's what you could do okay regarding the stickers we have a question now are the stickers available for on signal as well our signal stickers well the signal stickers i don't know signals that well so i don't know what stickers for signal actually means whether they use their own format i i have no idea the answer i guess would have to be no and there is a comment saying that the year of occurrence would be interesting as metadata oh that is difficult to get that information um i collected all these within two months largely uh in retrospect as it were and the year of appearance there is a lot of things that could be done in looking after the metadata there yes and another bit of information decays communication congress does have a sticker group um and i wasn't touched with them very nice so hopefully they will be using some of my work and um i hope that they will be happy about that okay thank you very much for your talks so on to the next one photovoltaics are you there yes great go ahead yes i'm here hello so i have to activate my screen share first waste that again can you see it nothing yet no unfortunately not why not ah of course so should we maybe skip ahead for now so you can have a moment for testing to see how the sharing works how can we do something to help now it works now we get it you can see it yes we can so let me put it on full screen i wanted to talk about freedom for photovoltaics so solar power at least more freedom so solar power is something that is included in 100 000 rules and laws from the eu back down to germany in this renewable energy law and i am a lot at home in bavaria and apparently the german states have different ideas as well and i just want to quickly explain my target and how i think we could get there and the difficulties i'm facing so the situation is of course i have a small house and it has a roof and apart from that i have the normal infrastructure i'm connecting my power from the provider but i also have solar terminal a thermal um um parts on my roof so i'm already using that but yes i'm i wanted to learn more and suddenly things look weird so if i try to include the power i'm producing into the infrastructure of the provider then that if i'm connecting that then that means that i potentially sell power so if i'm not using all the power that i'm producing it goes into the network into the power grid so in theory in practice it actually only works it only creates ac power if it's connected to the grid because it has to synchronize so as soon as i have no more power from the grid the device my device completely turns off so in that moment when i really need the power i'm not having any and of course it has to be said if you are selling to the grid you get money and so the provider is then expecting the full control over everything that you're doing how everything is installed how much is installed and all the interfaces everything and that's where it gets difficult because i think sun shines for everyone on this planet and i should be allowed to use it as i see fit so my goal would be yes sorry so the slides are still on the first slide could you see it check yeah no i did so something is wrong with the slides we cannot see the progress okay so now we are there the goal so full screen did not work out as it should so i was talking about this this slide you couldn't see that no but well now we care so yeah we have the provider the 800 liter storage for thermal solar and as soon as i want to enter the grid it gets difficult and now i want to use my limited room it's not perfect for me i have a southeast and northwest and the roof is not flat at all so i can't use it for much but i want to do a little bit and of course i especially want what i already said i want to use the solar power when the grid is has a blackout but that does not work but because in that moment when the grid drops out the ac power from my system drops out as well so i would need an element of course it has to be certified some coupling that connects and also disconnects my power from the grid so that it can also function when the grid drops out if i completely disconnect from the grid i also want to be free from control if i'm not selling anything nobody has to control me and of course they actually they say yeah that's possible but the technology behind it does not exist so my idea is that in the first step i want a giria solar power element it's a very small module it can at most have about 600 watts of power and then you do not have to register it then you do not have to take money if something goes into the grid and you do not have to pay taxes on it so you can already use a bit of the power in your own house some computers on stand by maybe the fridge if the sun is really shining something like that what i then need is a component that couples or disconnects from the grid if the grid goes down so i'm not taken down as well so especially if there is a blackout i still have power and then the next moment i of course want to add further components i want a battery i want further modules and what i want is i want to use a lot of energy that's produced there i want to use that for heating so if the sun is shining and i'm not using much much power i want to fill up my 800 liter storage of water and i want to heat that up and i want to save that energy that way of course this has further challenges we need a counter that does not run backwards so if i am giving power to the grid then the power counter it runs backwards but it must not be like that by law so of course the provider i have to talk to the provider and they have to build in a data logger basically that does not run backwards which adds further cost but apparently it's not that expensive what's more difficult and i cannot find any information on that no matter where i look or where where i ask so far that you have complete three phase power that can be completely disconnected of course certified and fully automated ideally if there is a blackout that you only use your own power for your own house and as soon as the power is back it's synchronized again and you can get power from the grid again such a solution would be necessary and it's possible it's it's not witchcraft but you cannot find something like that it's not wanted i am guessing it's lobbying people who keep that from happening from entering the market that's bad because we want to use our energy and we want to use less energy from the big power plants and it would be good to do that and that's why i'm trying and i would hope to find more help with this so maybe there is one amongst you who has further ideas or could further this discussion with me and if i could just start some ideas rolling in your heads i already met one of my principal goals and this started in the last few days that i wanted to talk about this because right now i'm having these problems and yeah so hopefully i met my goal and it's easy for you to reach me if you want the slides i can make them available if i told you something wrong i really say sorry it might be because this was a very spontaneous idea today and that's it for me yes thank you very much the internet was asking if they could get the slides could they be uploaded or should they write you an email where could i upload it i can do that of course i will i'll check i'm i put in my email address of course and it's in the list of course on macedon also my macedon account and yeah you can just talk to me and i will provide the slides so question what about balcony power plant with smaller things it should be easier from the administration and yes that is exactly the grea plant i want to start with with 600 watts tops and sometimes on the paper it's a 650 watts and with the ac converter if you add that you can have it on the balcony on your garage on your roof like a normal power installation so this thing is from the bureaucracy easier so it's less work it does not have to be included in this new list and you will not get money if that provides power to the grid so of course it's possible that some power that you don't use up yourself enters the grid but you have to accept that you have to accept that you're giving away the power you're not getting paid for that but of course you don't have to do the more complex taxes and all the bureaucracy yeah another question is would a power supply completely from a small usb with two supply wouldn't that suffice so a small usb i am thinking about that sometimes but that does not really work it only works for a short time when you think about it so it would only run for a short time and a blackout would last longer and english it's ups uninterrupted power supply and i thought about it and of course if it's implemented correctly oh an interruptible power supply sorry so that would be included into in the normal grid within your house if it's implemented properly and if i have it so if i have a ups it doesn't matter where it comes from from the provider or from my personal power system so it should work the same yeah thank you very much quite a few fans so the next talk the destruction of the vvv so hi i hope everything works we can see you and hear you great i want to talk about the destruction of the worldwide web first of all a small setup i'm not a lawyer in any way so this is not meant to be a legal information you should talk with your lawyer about that the background of my talk is that privacy in the private gets more and more complicated and there is uh should there will be a law that makes that that ensures that are no barriers for in the european union for the internet websites and web shopping for example in more and more areas companies think about how they can how they did not prepare their offers without without barriers and they have to prepare to realize the new law and everywhere there are there's a new requirement many companies think about how to solve that and many companies create automated testing to these requirements the wcr requirements for very very long accessible web content it's a long list and it basically doesn't finish and it is there's still ongoing development some criterias in these world wc3c can be verified automatically however some are not verifiable automatically and that must be done manually and unfortunately that's quite expensive and therefore those are just a well developed suit a development tool and developers can can can can check that and they see hey here there might be an accessibility issue and check whether that's really that's of course offered with some everything is can be done optimized and therefore there are different companies and they try to connect these automated testing services with the automated solving tries there are accessibility overlays example this one one can find it here accessibility we can see it and this is the website and down here on the right hand side you have this small accessibility icon and if you open it you get a list of of things you can do with accessibility for example it's it's a long list and nobody can select it for every every website and another issue is that several of these options are can be done via a mobile networks that are only CSS or JavaScript changes and where accessible mic up is used there are a lot of options and many options can destroy something for example currently it's completely broken yes it looks like this and that's the next step these accessibility overlays usually destroy several things quickly and that's not acceptable but that's something the user can control however these the companies that offer these services always talk about AI and offer screen reader support keyboard navigation and all the other accessibility features that are required but what they do is sometimes really bad because that way pages are completely unusable sometimes and lose all structure because that AI tool does not understand what happens on that website what is offered and what the context is and another interesting issue with accessibility is that the the tools require that you have a compliant site before you can include this tool and if they are legally required there are a different number of justical problems they have there are a number of different offers in the question page there is an interesting blog post by Adrian Roselli who is an accessibility expert and so look at all the issues and don't use those services but sit down and look it look into accessibility if you need to update your services yes thank you for your presentation put that into the pad and for chaos zone the inclusion operation center exists where you can get help your operation center has questions about accessibility on the web great there are no further questions so we will continue to the next talk thank you very much yes hello let's have the screen so take digital politics series three for once I want to talk to you for five minutes and give you an overview over the formal structures of Hamburg so let's begin we got the executive the legislative and of course the executive but for us now it's not as relevant so the executive is headed by the first mayor and of course there are senators as well and each of them has their own office so yeah he is heading them the german word is the natskanzler yeah it's not necessarily a bad thing so there is one guy who is responsible and if some other department wants to do something with digital works they know who to talk to and they can just say we want to make a project we want to do something for the specifics and we want to adjust software everything is coordinated there so that's not necessarily a bad idea that everything is in this office and there is someone who's actually competent you might not believe it but now the problem and I have to talk about the legislative so we have the parliament and the senate and there is a a planum of course with a lot of smaller groups who work with topics of the eu or different specific subjects so we could now think well there is quite a few universities or colleges with computer science so do we have one of those working groups talking about digital topics so they could provide tools and have proper protocols where the senate has to explain to the public what's happening after each meeting is everything running as expected just like all the other working groups have it and then there's a committee that's a proper word so this committee could make suggestions and others but we do not have that in Hamburg so basically there is no one in parliament who talks about digital topics there is an under committee but that's very specific about spending and it cannot talk about things on their own accord but they have to be told what to talk about and what to investigate and so it's very limited so what options do we have for corrections for digital politics during this term well there's not much we can do every five years there's a vote there's an election and since everything is directly dependent on the first mayor it really depends on who leads the government so who makes decisions and it's very difficult when you look at Hamburg since 1949 to expect a change in government so it's very rare that not the SPD the social democrats of Germany were at the top so since covid we know that it can happen that something happens within a term that you did not expect and sometimes you really have to act quickly even if it was not agreed upon right after the election so what can we do we have to work quickly with all parties so that all the parties agree and commit to publicly bring digital topics into the focus before the election 2025 and it has to be public and there has to be a lot of pressure from the public so we do not get just buzzwords but real change and that's already it yeah there's my contact info and of course i'll put it into the pad yeah thank you very much somebody's adding so they are making the university so the university is shrinking down their computer science which does not help obviously yeah no questions for your talk let's continue with tbs your where is market so can you see my slides i can see you in the black background but no slides but apparently it only works with these slides i can see the slides now okay but they're loading yeah no great yes welcome to my short talk about where is market a small project running through the last six years and it's about farmers market where you can get fruits and vegetables but also flea markets and all other different kinds of markets you can remember for example the fish market in hamburg and the project is a website where you can find markets in a city and the project answers two questions first of all where is the market and when is the market and you can see these information on the map and you can select your town and city or your position and then you can find the closest market you can select and now today in all markets and the icons show you all the information the address and the time and the day the market is operating okay the data is from an open data project usually from that city and are just visualized on the map because on the website of the towns it's usually a table or a pdf and it's easier on a map it all works on a smartphone looks like this and 79 towns are there now so far it's a manual process that accepted and do the entry of their own town and care about it because nothing is worse than old data any year or their differences in winter and summer it should be updated a number of people out there and you can also be involved you live somewhere you perhaps go to the market and you can just take the data format small jason file and you enter the information and perhaps optimized if you have the data from your town and have an up-to-dating script and that way you can enter the data the information about your town the GitHub repository has all the the necessary information to participate and not only writing new software and design but you can also participate in the website itself but you can only also only just add to the data it's also classified easy things larger issues and there is a participant guide contribution guide on how to add the data you have to create three files something about the town and three me file you will get feedback if you had something the files are realized you can try it on github here and you see whether everything is fine and i will get in touch with you or somebody else if whether everything is working oh that's an invitation to participate it's all you will find some github and there are a couple of different you can probably see me there is this beautiful t-shirt you can create yourself or there is a vector graphics on the github but you can even get a sticker like this they i had 5000 printed but there are still a couple left so call me and i will send them to you or you print your own the everything that's available i saw that there are questions in the pet and i tried to answer them the question for open street map and integration into open street map we tried that we discussed it before but nobody worked at that it would be great to have the data not only in this project but to update that with open street map and check whether they are working together and how to update them that also helps to have more cities involved and the other question is about usability and you create a town with a city with several cities included in one because that's also something we worked on there is a pull request for that or a branch and finally yeah nobody did it so far so this we need partners for different towns so if you want to add the data of your town you're welcome to there are a couple of code improvements possible yes you're welcome to participate i think there is another question yes thank you for your talk and for answering all the questions but we have to finish now and all presenters are invited to wave to the camera if you want to and thank you for the presentations and thank you for the viewers and all of your questions there is a short break and at quarter past four there is a talk about critical infrastructures by honkhauser have a great divon
