 Ladies and gentlemen welcome to the Congress infrastructure review we start with the all right welcome this is Stoffel I'm Momo we are from the internet and obviously first things first when speaking at a conference you have to show your KPIs right we often are now have 99.47 percent uptime two small incidents were very sorry but but it exceeded our nine fives as a la so we're all good yeah infrastructure right infrastructure starts with building a backbone this year obviously due to high bandwidth demands last year we started to just go ahead and build some more bandwidth so this year we have 200 gigabit alien wavelength via two carriers to Berlin where we meet transits and appearance and also we do have a hundred gigabit by dr teeter com locally which means we increased by 150 gigabits also we're quite a lazy bunch of people so this year everything we did was completely automated every configuration any access which you had came completely from net box which is an amazing open-source project by this lotion and it was our single source of truth all conflicts were automatically generated by it and no humans were harmed during creation of the configurations the knock guys are shaking their heads kind of so yeah some numbers this year we had 286 Wi-Fi access points we had nine routers eight of them on site one in Berlin and 186 access switches so yeah those are numbers but to put it in perspective congress grew by location I know kind of twice in size also this means for us that we had to bring up hundred seven more access points and 53 more access switches regarding the Wi-Fi we've seen almost 25,000 unique MAC addresses on our Wi-Fi controllers and speaking of access points adding to our almost 300 access points we also saw 558 interfering access points so please we said that every year but please don't run your own Wi-Fi if you have to we have a page and a wiki for the network where we tell you how to do so which channels to use put your tx power low and everything please read that those 558 interfering access points one read that and complied thank you seabase so next year please read the documentation so yeah usage numbers our average bandwidth usage was 3.1% or 15.9 gigabits in peak we see 10,800 consecutive Wi-Fi users at the same time and our peak bandwidth usage this year was 7.6 percent or 38.4 gigabits so this means we have 3,148 more Wi-Fi users than last year and 3.8 gigabits less than last year but on a positive note everything we did work quite well we're done a day minus one and we're quite happy with all the results everything we did here would not have been possible without our sponsors so please give them all a warm round of applause and with that I'm gonna hand over to Stoffel thank you I'm very proud to announce that we this year have completed our first joint venture with the cows from mid-long we now provide like every good telco to should do different services for different users we also have very very amazing zero rated stream-on service so that everybody can watch the both publications this is what our users say this is testimonial we provided DSL network to kitchen translation booths and project light home and I think we might do so until the bright band out spell has finally succeeded and yeah now it is available at your closest c-point so now grab your stuff and go to go for it on a more serious note we're running out of hardware so if any of you or your organization has good quality gear with at least 10 gig uplink ports there is a non-profit called event info when a lot of our equipment comes from so please get in contact to those guys and girls and if you want to donate them to this and non-profit very good and as a bonus point if it also supports this gear power over ethernet you get special comma points and one thing please during tear down it will start very soon don't plug unplug anything that's connected to our network if you want to be helpful come to Hall of Four to the knock and ask yeah don't swim randomly unplug equipment switches access points and fibers yeah please leave them alone use more bandwidth but with useful stuff you know we had it last year fine make something new yeah yeah so so please use more bandwidth but with useful stuff I have to only thing I have to say yes thank you very much and see you at camp next year are they questions for the knock yes okay if there's no question please raise your hand okay vice-versa if you have a question raise your hand if so go to the microphones please do it quick I cannot have a sale if you don't know who it's called lights please photons showing people if there is one over there I think they are at microphone for microphone for please is it just me or was the Wi-Fi shit at the toilets this year we are aware of our shitty shit advisor ratings feel free to donate more a ruba access points thank you another one okay thanks Mike number one what are you using to provide the data in Grafana Prometheus so it Prometheus thank you okay if that's it you're last go for it now it's microphone number two is it possible to still improve 2.4 gigahertz performance or are we just at the physical limits sorry the 200 gigas you mean the 2.4 gigahertz I think just use 5 gigahertz and that's it yeah I'm trying that's some hardware try harder thank you a lot of okay thanks and welcome to your stage we have some numbers for you and for that I'm going directly over to Thomas hi Pog means phone operation center and we deployed a whole new PBX this year that's all IP based so it's completely new for us to have that in this large scale we have tested it in several other events and what you see here is the sync overview so there are the small dots in this map which covers the whole area our deck base stations and all of them are sinking over the air so that are the green lines in the picture and what you see on the right is the hotel decked so we had hotel decked in an H hotel this year and in the log-in hotel yet this year and we had a drum deck deployment so luckily you could have phoned in the drum as well so in the former days we used to have the famous Pog case as you see on the picture here and that involved many cables so we have to patch all antennas dedicated through to out to the PBX and this isn't needed anymore so we switched to a more convenient deployment using virtual machines and we automated all things as you know that our registration is now completely self-service and that is supported by several virtual machines so they are listed there and we use MariaDB as database for all the extensions and routing we have prepared some usage stats so this year we reached the numbers of registered decked handsets at day one so the number of decked handsets which were registered in the last year on at the end of the event we have reached that in day one 10 a.m. so and that that was 2.5 thousand and today we are at 3.8 thousand so we even increased that number and we look forward to have more decked handsets even next year or at camp so yeah to see some numbers about the calls then we have prepared a graph of deployed decked base stations so over the time you see the number of online decked base stations so at the end of the event so after deployment finished we had 62 base stations and you see a drop in this graph and that is due to an issue you maybe noticed that was on the 28th afternoon and that was due to performance issues in our database so there was like a full table scan which shouldn't be there and we unfortunately didn't notice that before and we just fixed a thought procedure involved and we started the decked registration then so the deck process registered all these base stations again that's why the drop is in there and by the way they be our deployment was online since the 22nd of December this year new features so you have noticed that self-registration is now possible so you can't you haven't to queue to get your decked registered we have the thanks yeah we have the hotel deck deployment because we use IP it's much easier to deploy decked in several other places using VPN technology in hotel and drum as well and we have support for several different other handsets so we haven't had before so I'm using the old paybacks it wasn't possible to use like Panasonic handsets or Fritz phones yeah you can do that now but we have found out that some phones only receive calls and could not make calls so don't know if it that is useful but yeah we figured it out we had a fax service this year so you could send us faxes and we received I think three or four faxes it's still a thing yeah so yeah and we had a special occasion this year at some point we run low on extension numbers so we used to have four digit numbers and we decided what should we do if we run out of numbers and our approach was to extend that to five digit numbers to make more numbers available if we hit five hundred available numbers and this happened this year so we had lower than five hundred available numbers to create new extensions and we extended that to five digit numbers um yeah so we had a new LDAP phone book this is completely new you could use that on iPhones and we are still figuring out how to use that on Android as well we had a premium zip service that was available to several other fixed phones and we had of course an amazing time to market because we were online on 20 second yeah that's a picture from the drum deck and yeah that's it workshop make yourself ready questions to any questions come up then questions from the internet hello it's microphone number six i think mike six what's your fact service vulnerable to the recent fax box it's from the internet it's it's somewhere else you know it's in the cloud yeah don't know security by obscurity so number one hi is this working yeah hi i'm asking for on behalf of all my friends who have five character nicknames is there a chance to always have five digit numbers maybe all request we already thought about that for opening up the four digit extension and the five digit extension from the start and then only allowing five digit extensions until we hit the five hundred which would be available if we only had four digit extension so maybe next time you couldn't already register five digit extension from the beginning thank you number one again okay um you had this nice craft where we saw uh how many people were booked in and so when there were different colors but i didn't see a legend which color means what can you explain um yeah the uh you mean this one or okay ah okay uh yeah you can come to the pock desk we still have our display up and running and then you can see the legend below the screen okay thank you so this is it for uh the pock your applause you're not sorry no you're not sorry so up next is the vock right right we are the video operation center and we do wink do we wink with us come on and wink with us yay so we're doing video and video is hard and we would like to explain and show you why video is hard let's start with why video is hard so we had five main stages this year three cameras per stage and you may have noticed that in hall c there was some reverb the solution to that costs lots of money you need to buy almost all the molten in Germany probably to remove that somebody asked us to remove the reverb from um from from the audio but it's impossible it's physics this was the second congress we ran a vocto mix for every hall uh it's an open source lecture uh video mixing solution that we partly developed ourselves um there were a dozen air fuss there were a dozen air fuss and uh other crews running similar setups um and we had our first uh satellite connection to a dutch ship yay and um there was uh the satellite connection works with by hopping satellites and uh we were successful in uh using just one hop so with the whole tour oh the whole interview was in uh went without the problem so technically similar to yastia although really a lot a lot a lot better we're doing a complete separate audio mix like there are people in this room mixing the audio for you and there's a complete different crew mixing the audio for the streams in the recording and they all sit in the centralized room so all audio from all the main stages is traveling there is mixed and then the control sickness are traveling back so they can see what's on the stage they also have a zero latency video link from all the stages there's a room where you have uh the cameras the cameras in the back visible for them fun fact if you connect a handheld camera to them that makes the audio angels seasick because they have to watch that for a complete talk we have 142 microphones all all go over the halls these are microphones for the hands like on the podium some in the in the ceiling the question microphones and all of them are mixed together for a special mix just for the streams and recordings we generate 15 independent mixes there you see all the volumes of all the mixes in our multi view we did record every microphone for the complete five days not just the talks also the nights just to have a backup available the backup is traveling through the complete halls via multicast fun fact multicast is hard to coordinate all those people we need a really good working infrastructure and we have this intercom system with belt packs we have these this installation and it's probably one of the biggest this year and additionally to those mobile belt packs we have the fixed installations they are using decked on the wireless and sorry pop we stole your time slots a little bit I think they also use multicast in the back end fun fact multicast is quite hard that didn't work on day one for the complete day so as you can see we had a lot of special requirements in our network site thanks to the knock for being being very patient with us thank you um fun fact multicast is really really hard the first time we have a rabbit a rabbit arabic that's right one and chinese translations and releasing is about 90 done and expected to nearly finish tonight so we had 40 wok crew members 172 video angels and the 1600 hours of angel shifts we love you angels thank you very much and I know shock these are the guys who provide the technical infrastructure for all these lecture halls and we are shocked we are those who get the show running so we are the stage manager and herald operation center thanks and that's an example of who we are yes that's one of our heralds and well you see the heralds a lot or those who are in the lecture halls while the other part of our team the stage managers you probably should never ever see or realize because they are fixing all the problems so that the show is running smoothly as best as possible and that you don't see that things are not going fine or well and we cover over this and the herald presents the show as bad as possible so that you have a very nice experience so we fix all the problems we ensure that everything is there and everybody is there for the show and we keep the schedule um yeah to this year we had to increase from maintaining four stages to six stages because we didn't only add Eliza as another stage you also had chaos west over there as another very cool assembly stage that was also meant by a whole stage management and heralds team so we had to optimize a lot and we had a 250 talk 205 talk there 167 official talks and additionally the chaos west talks three quarter of them were in english so all of them had to translate it into german and the others into english and everything and then some other languages as well which is the translation team which we also think is a very good team that will not present something here but i think is due an applause as well yes um our team is um 55 stage managers and 42 heralds um okay it's not the best uh slight but whatever and we have another cool crew that is helping us with the crowd control this year so i believe everybody in here realized that the queueing up and entering and leaving the halls was much better than last year so this is some of our optimization that took care that we did but it wasn't only us it's also this very cool audience that we have it's an excellent audience and without this excellent audience nothing would be as smoothly as we experienced this year it was very easy for us and thanks to the audience so now one of our biggest issues that we had to fix or something that we actually could focus on is that we have enough speaker water cheers subtitles you make yourself ready you already are other questions for walk and shock or shock some shocking questions maybe not i don't see any mic or someone is heading to microphone number three uh yeah question for the speaking to the mic please so a question for the rock um we're running the audio as a 67 is the video being run as st20 110 or similar video over ip um no actually um the video is uh running from s via sdi from the cameras into a computer behind the stage and uh mixed there by a software you saw and from there on it's it's on the same computer recorded to disk and stream to the internet so the video is not leaving this computer it's entering via sdi and then directly used there the audio is all is only traveling via the network for backup recording and monitoring it's actually also mixed behind the stage and not really that the production audio is not traveling through the network it's just for backup and monitoring thank you another question internet number six please yes the internet wants to thank the walk because uh otherwise they wouldn't be able to listen um and to see and they also want to know um what kinds of lenses and camera bodies were used uh i don't i can't answer that question i'm sorry um but if you if you want you can send us an email or come to the irc and ask there there are a lot of people answering all questions about video there okay thanks feel invited another one okay then thank you for short and subtitles your stage right so uh welcome to the subtitles infrastructure review and well so we are doing subtitles for the released videos by the walk and um our primary focus is on on having finished subtitles for the original language of the talk and then after that maybe we can also work on translations for these subtitles in different languages but really the first step is getting the original language right and there's essentially three steps to to actually finish subtitle well first of all we we need to transcribe what is set in the video uh so we really we use the speech recognition software that gives us a basic transcript and then we have angels working on that to to bring it into a nice readable transcript that has not too much text in in one subtitle and goes with the flow and really fixes all the bugs that the speech recognition software introduces into the subtitles so that's the the transcription stage then once that is finished we we again use software to align this transcript to the the audio file so um there's there's some matching of when the subtitle actually appears in the video and then again we have angels working on that aligning checking if this timing stage really works so adjusting the the timings of the subtitles and well then also afterwards doing quality controls or fixing typos or whatever else happened in there and now we have this handy chart here which is the the basic progress for 35 c3 and this is data from around noon today um so all of this might potentially be outdated already um everything is in seconds and well the the big orange block down there is just basic seconds of things in the far plan um then the the next small thing over there is already finished subtitles which at the point of this chart was six subtitles um and again six of those in the original language we don't have any translations yet so there's also no no seconds translated here then there's a whole amount of of subtitles in the transcription stage which is this blue part here and then furthermore um quite a lot of subtitles in the timing stage which is the green bit here and then the small bit still in quality control which is the the part on top and um to to put that into numbers we had over 106 angels working for us this year uh of which 75 percent chose to do at least the second shift um in total we had 381 hours worked uh working on 79 hours of material we have so far had six releases for 35 c3 and hopefully getting more and because on day one there weren't videos available yet we already finished 10 subtitles for last year's congress then there's still 49 hours of material transcribed which is a 63 percent increase over last year um 27 hours of of subtitles being timed so 23 percent more and 17 hours checked so in quality control um which is a 42 percent increase over last year uh right so once we have subtitles we can do funny stuff with them like generating word clouds um so this is from the at the time of of the creation of the slides the the talk that had the the fastest speaker and you can maybe guess what it was about from looking at the word cloud so this is a talk in german and it has a 166 words per minute which comes out to 1095 strokes per minute so really if you if you want to type that then you need to be really fast um or maybe you need to be multiple persons right um so well to organize all this we we use a state of the art eventually consistent log free distributed database uh which which has served us quite well this year and also last year and at this point I want to thank all our hard working angels for the support and also especially to the heaven for for commemorating all our wishes thanks sorry um yes just just one more thing um so if you if you have time to spare between this congress and next year's congress then you can still work on subtitles from home uh just go to c3subtitles.de and if you're looking for finished subtitles you'll you'll find that on this link at the bottom here and I'll also put these slides online then and and just check the twitter account for the link then and now well yes if you have any questions then or well whatever yeah are there any questions for subtitles or blah forever any questions um internet is not asking anything this time doesn't seem so okay this is your applause thank you for the subtitles um coming next is c3 gelb and of course this is a hold in german because as it would be c3 yellow and um actually you have not been told that is in english so you preferred your things in german so that will be thanks thanks a lot again for the translation team I'm sorry didn't do it keep free your stage thank you very much um yeah we are the new team what i just educated this congress that's why we are still a little spontaneous on the way we are c3 gelb and we are called because we give out letters maybe some of you know what those are those are the teachings for paragraph 43 the infection law you need that if you work in the backstage kitchen or want to cook as an angel for the many other angels and in addition we are responsible for that as little as possible get sick from us um yeah our data nina is in front of you we have collected a few numbers for you there is a tendency now about what we are doing is just sharing gloves for the bottle sorting angels but also for other layers where you could potentially hurt your hands and disinfection means to distribute certain parts that we have here um there we have now roughly a thousand pairs of gloves also given and washed regularly to secure them uh you see 2100 disinfection units that are these pump locks when you expect such a wash such a disinfection bottle 42.234 cadet diplomas are learned and we have called with the cert and from which there was also no case of congress test that means we have done our job relatively well and since that was very much wanted to publish their statistics because they have been here since this year, too, I will now continue with the microphone. Yes, hello, I have the tasteful task to send you bold greetings from c3 wok, which are unfortunately prevented, yes, the c3 wok would be accepted today under no circumstances at all, and that's why they are constantly busy with the further production of weapons. Yes, we have a few data for the village to look at, sorry, okay, there is also something like that, great, thank you, new here, sorry, yes, so the c3 wok has about 500 kilograms of dough now so given to the people in the meantime, you always have to compare such a football field, so if you now, let's say, distribute 100 micrometer thick layer on a football field, then you would be able to spread such a medium-sized to large football field with a 100 micrometer layer with it, football, the yes, the further there was, as a reference, about 18 kilograms of marmalade, 20 kilograms of nutella, 35 kilograms of apple, I have not calculated how much that is in football fields, then special skills of the c3 wok are now döner weapons, junk weapons and rum rum weapons, about 200 hours of work from volunteer helpers, so people who just passed by are on a weapon, they just went in with them and that did not work on the angel system, so there was not even a t-shirt for it, so they have an extra applause for them, I think, thank you so and last but not least, c3 gelb, by the way, is also on twitter and on youtube, we are now beginning to just bring this hygienic topic a little bit forward with a video series and we have now spontaneously turned the guys from methodically incorrect a little info video because you want to see that, just take a look, we would be very happy no, c3 gelb so any questions for c3 gelb are they or not internet not one two three four empty thank you so kasse presale is next your stage hi my name is rami, I'm speaking here for the presale team and the cash desk team, we are the ones who handle everything related to wristbands, we sold all tickets again prior to the event in our presale, a part of them through the voucher system that we've been using for two years now and I don't want to go into the details of how it works, you probably missed if you know it but it's possible to get a voucher if you redeem a voucher, so we're building voucher chains and this year the longest chain was 14 vouchers long, so there are some groups that were very good at replicating them, the average payment duration between creating of an order and payment was 1.8 days, this is two days less than a couple of years ago, so banks are really getting better to there, we also sold a number of tickets openly on a first come first saved basis, during the first round of that we had network traffic surpassing all of the records that we had before, we had 16,000 requests per second on our queuing proxy and that's already averaged over a five second period, if you want to know more about the software we're using, we talked about this in more detail on the infrastructure review two years ago, so I'm not going to go into it again, you can just watch that video thanks to c3walk, but there's some numbers that we want to give an update on, we handled 1,521 support cases with only four angels in the months prior to the event, so every tenth of you has sent us an email and received some support and we have some very bad news and we're really disappointed, I'm now going to show statistics that we already did two years ago and unfortunately it's gotten worse, in the presale 23.2 percent of orders were created by emails either ending in gmail or google mail or on domains with an mx record pointing to gmail and we're really disappointed that a fifth of our community supports those kinds of monopolies we have some more providers here gmx is huge in germany of course posteo is still getting larger webd is a bit on the decline mailbox.org is now showing up in the statistics compared to two years ago and roughly the same amount of users are using an email system hosted by the ccc by their calstrev or alpha or something like that so this was the presale now for the cash desk this year we operated seven cash desks to scan your tickets we had 48 cash desk angels and eight troubleshooters and we had a peak speed of 41 transactions per minute which meant we took on average 10.2 seconds to give out to scan your ticket and give out your wristband you think it's a lazy job to be a cash desk angel but our angels walked 35 kilometers during their jobs back and forth between the back office and the cash desk if we if we put all of our wristbands together we can roughly get to the central station and i think we had certainly over 9 000 wrist skin irritations we estimated the force that is required to crimp with wristband which is roughly 160 newtons so it takes about 1.29 joule to crimp a wristband and if you need to resupply that energy by drinking mate it would only require if our calculation is correct 45 milliliters of mate to crimp all of the wristbands here's our chief physics operator during the experiment our waiting time was always less than 10 minutes which compared to 39 minutes last year makes us very happy but most of that is due to the fact that we didn't need to sell a public transport ticket so we put those numbers live this year i'm out running out of time this was our most valuable angel it kept people from going into fast see you next time questions no q&a for for the check desk and the cash desk and the check desk is all nice cash desk urgent delivery from the cows post thanks so much we had a cows post so let me check it's to the stage infrastructure review that's clearly me it's an original so so i'm gonna read it so during during the congress the cows post processed more than 2000 postcards to more than 37 different countries and the default world we successfully operated four different mail drop points fun facts we bought all the postcard stamps at the leipzig central post office and they had the store next to the venue refused to sell us anymore how great is that we delivered trace route ping port scan and pgp encrypted handwritten postcards great we had some broadcast issues because someone submitted 200 printed bitcoin scam emails we delivered spam messages and text porn we successfully operated in autonomous night mode during the day three to four office shutdown use more mail thank you now from from the postcard to the gsm service thank you it's your stage and we are running the mobile telephony network here on this congress so what do you need to operate a mobile telephony network well the first thing you need is some um is the purpose so as you probably know in germany the network is not that great so we decided hey we want to do our own one and better than that we're using some open source stack called osmo com open source mobile communication and we are using this congress to really test how good this open source can run against all the networks all you need to do to join a network is just buy a sim card and then you can run on it it's flat rate you can call everyone in the world for three euros you can get incoming calls and this is only for two days but you can even get internet this year so on top of the usual 2g network gsm we provided 3g network umts for the last two days and the speed could be quite good we don't filter anything but sometimes it could be quite slow we'll see well it is still very experimental and we still need a bit of fine tuning but most of the time it works now what you also need to operate a network is not only the stack but the right to operate it um the base station operates on a license frequency and you need to have a license for that sadly in germany all the licenses have been given away to the three most big mobile telephony networks but we contacted telefonica and they were friendly enough to give us four frequencies and thanks to them we could operate the gsm at this congress so thanks telefonica and for umts we cheated a bit because the band we're using 850 megahertz is not licensed in europe this is mostly used in the us but we have base stations which can go on the band five so we didn't have to ask any operator this time we just asked to ask the bundestats again tour they were also happy to give us a frequency for umts so that went well now coming to the equipment uh the boxes are quite small it's not the huge base stations which you see outside here you see on top uh 2g base station with 200 milliwatts which is quite good when nobody else is transmitting on your frequency and on the bottom you have umts base station which is only 20 milliwatts but it's still enough we deployed 10 gsm base station and 13 umts base station all around the congress and we hope we had coverage for everyone if you didn't have a coverage please call us and let us know so we can go there and put some more points um a mobile network is quite complicated you see each bubble here is a different service which needs to be configured and last year it was a disaster um we spent the whole congress trying to make the network quite work making some calls and at the last day you were able to make calls and it was kind of stable so it was not very good this year it was very stable and the only thing which was unstable was actually the internet connection it worked from time to time and sometimes it was low so it's a huge progress for the uh osmo com stack and we can say we can now operate stably uh a network so that's that's a good thing we had so much free time that we even tested new features like handover so you can run or take uh hoverboard across the the whole congress without being interrupted we also had 3g voice which we didn't have last year and you could on your phone enable or disable 2g or 3g using a usd code so we also now support usd code and we dropped a lot more base station than last year so it's a it's a good progress the only the only issue we had actually was kind that we created loop of one of our switches so we disabled not only our network but we disabled a whole building the internet network but the the knock was very fast knocked on our door and taught us how to really make a network work so that went fast and we had so much time that this is our ticketing system and we had to create fake tickets so it doesn't look that empty you can drop by and it works quite well actually so sharing the ticketing system now the um this is the opportunity for us to to test really the osmo com stack so if you see something that the network goes down goes up it's not because it's instable it's because we have too much free time and we want to test features so else it worked quite well now the installation worked also very smooth day zero everything was installed day one we enabled gsm for everyone um then um t s optional which you had to dial we mts everywhere and it worked really great now a bit of statistics this is not too important we had 900 sim card the purpose is really to test on a large venue not just in the lab so that's good but we had a side collateral damage is that very old fault could not use a network to phone that the problem is that because we had 3g voice we used a quite uh newer codec and the old phones were not able to use this newer codec so without you new with the new phone you could only send them sms s but not make voice calls so that's a pity maybe it will be fixed but at least the rest worked about easy we don't know how to provision them so just buy a normal sim with 4g lte um osmo comes itself doesn't support it but there are other stacks so we just have to just we have to integrate it with osmo come so it interoperates and please join us the osmo come community is quite small and there's plenty of things you can do so please please join and the same thing if you want to see 5g contact us i mean it's a real opportunity to have 5g on a large scale and say we're the first one it works on our all space so yeah thanks for everything and join us any questions for gsm let me check internet is not asking something tools mt3 number five maybe i can't see it can you help me over there is somewhat number five pech gehabt no it's not okay then thank you gsm so yeah thanks a lot we are heading to the last team which would be the lock but before that after that the infrastructure show is over and it's the last the last show at borg so i would be very very happy if when they finished i think you have a colleague who will join later on maybe it'll surprise but after this colleague comes on stage and when he's finished with his talk could you please make so much noise that the guys over in adam really think what is happening here this is a contract we can achieve yeah okay hold on but i want the adams guy everyone over there thinking why am i sitting over there and not here can i do it so welcome with the warm rows around of applause look thank you hello everybody we're from the logistics operation center and we're going to tell you how all the big stuff gets here maybe you can turn it up a little bit how much closer okay so yeah we're from the logistics operation center and i guess you're asking yourself what does the lock do because i don't think we had an infrastructure review yet so we do mostly this getting all the weird stuff here and back again this is about one cubic meter of lego duplo yeah we like to say we're the infrastructure of the infrastructure we make sure that all the big stuff all the big things and stuff that the teams need for their operation get here in time ideally before the teams get here and then disappear afterwards almost oh yeah so our most three main points are the transports storage managing supplies and then we have our help desk that's very helpful to everybody this is not a mistake yeah this is our storage facilities we run like the whole year around we have two storage facilities one in berlin one in leipzig the berlin one is more for the teams like the nicely packed pallets and mostly nicely yeah mostly nicely and all the big bulky stuff like the wood and part of the backdrops and stuff those are in leipzig in german we call it raffel yeah and here you see them in full and in empty yeah we have a bulk of transports here uh from the transport we know of their 13 7.49 ton trucks not 7.5 tons 23 40 ton trucks 10 sprinters uh yeah all included 68 pallets from berlin with our very own 40 ton truck driver angel and our very own 40 ton truck and and mind you this is only for the build up uh yeah but our own own 40 ton truck driver this was really awesome this year he came by and said he wants to do help out and he's going to be here from the beginning all the way to the end driving our stuff around looks like this and very fortunately no one got hurt this year we had no accidents everything went fine except for this and this was done by the professionals but no one got hurt except a couple crates no yeah yeah then very quickly we go over some software we're short on time so we're gonna do it quickly uh like the other teams we do software also and um oh wait what there's the software oh all right there's a mix-up um then we do all the other stuff that we do beside the transport and storage and we do the software afterwards seems like uh yeah we have we're doing a bunch of stuff like free everything so before everybody else gets here uh cause the knock is very very slow uh yeah so mostly we do the stuff that we already talked about but then additionally mail deliveries shuttles hostels supply orderings stuff that people forgot but it's really important right now that they needed build up and tear down then all that nice light foils you see around the toilets and the halls the vehicle fleet desks and table distribution we got handed over from the assembly teams who did an awesome job then garbage containers because everything needs to go back out and uh yeah here from the uh ordering and supplies you did all the shopping yeah uh mower who's somewhere there at me uh did the shopping this year we ordered about 1.3 tons of limes for chunk and it's I think it's nearly empty yeah and we we bought all the crushed ice and the basil from the metro so if you if you're in Saxony and you want to buy crushed ice or basil from the metro not this week so no crushed ice for new years all right some then the quick mix up our software we don't do it very quick we had a nice mapping tool we've been using for a couple years to map out spaces in the logistics hall four um this year new we uh got rid of a huge un-maintainable excel sheet where everybody had their uh transports oh no google google uh google docs so we wrote a software for it um where we can have a nice um overview of our transports uh then um last year last year uh we we we we we we we renamed ourselves to the lost operation center so yeah this year we had a tool yeah we find our stuff like our forklift or our trucks we lost a seven and a half ton truck and the scaffolding last year we didn't want to talk about that well I mean we we found them again but they were lost for quite some time so um this year uh and they built a awesome uh tracker device with gps and uh lora and um this was a nice beta and it will be functional for the camp and then suddenly happened this year because there was a need for it during the congress somebody wrote a shuttle planning tool uh to route some cars and shuttles around all right here come the the juicy details for you that's for the nerd yeah uh we had about 33.9 kilometers of shuko cables about 3.7 kilometers of 16a cables yeah I guess maybe we can so yeah you can and then uh 1600 power strips with just mehrfach steckdosen so lots of those uh thanks again to the awesome c3 power team and all the angels who helped out running those cables around and through the ducts in the floor and all the greasy work some more steps I want to mark the 330 torx bits yeah so if you see torx bits we are running short about 330 torx bits so yeah we used 5000 screws and 48 uh primatic staples uh those were all used for the from the building crews who built all the nice uh backdrops and the room dividers and all the fake walls and the beautiful stuff you see around all the decoration in hall three and the uh disco drama in hall five what yeah and for that this is what they only for what we bought knew this year not the stuff we reused from last year got 15 kilometers of uh theater latte 2.1 kilometers kvh and uh about four uh four thousand square meters of hdf so quite a lot of stuff and uh yeah I would like to thank at this time uh all the amazing amazing artists and build up crews and I don't know how to describe them but all the people that build all the awesome stuff that make the uh congress look so amazing to speed up a bit yeah yeah torx bits but on time too yeah some more stats oh yeah this is the most important one 853 rolls of tape this year it's about 800 kilograms two pallets full of gaffer or 33 kilometers which is almost 12 times around the messer yeah and maybe some of you already noticed we had a very empty hall fours this year because of the lecture hall in the hall four so this year we have twice the upper twice the fun yeah we had to the because the lecture hall is in the same hall we had for fire safety we had to clean out all the storage so it was outside in containers so as we speaking right now everything is moved back into the hall so we can move it back out of the hall yep and that's it for us yeah congress is far from over most of us got here on the 15th and we're going to stay till the fourth to clean everything up but come help as you helped before and help during the congress we need more help and I shall keep this brief dear community we built a city a home and during this build up and the maintenance of that city no major accidents have happened and that's a very very great thing please keep it at that for everybody leaving please get some sleep before you leave please let the drugs wane off just be responsible and for everybody staying here for the tear down stay safe thank you very much for helping you're the angels
