WEBVTT 99:59:59.999 --> 99:59:59.999 Herald: Hello and welcome to Infrastructure Review. This review is 99:59:59.999 --> 99:59:59.999 being translated into a lot of languages and we don't know yet which one, but the 99:59:59.999 --> 99:59:59.999 c3lingo team will be on stage and will tell us how and what it did. I'd like to 99:59:59.999 --> 99:59:59.999 start, as always and every year, with the NOC, right. So please give the NOC a hand. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Momo: All right, everyone, welcome to the State of the Internet manufacture report. 99:59:59.999 --> 99:59:59.999 This is JC, I'm Momo and we're going to talk to you about what we did this year 99:59:59.999 --> 99:59:59.999 for the network. So obviously, organizing Congress is a quite tedious task. Took us 99:59:59.999 --> 99:59:59.999 about six months of pre-planning. We came in on the 15th, did a fiber day and then 99:59:59.999 --> 99:59:59.999 it took us from the 18th and will take us till tomorrow to tear everything down with 99:59:59.999 --> 99:59:59.999 like 20 to 40 people. And we'll be busy wiping every device because that is 99:59:59.999 --> 99:59:59.999 actually what we do every year. We delete everything. There are no logs leaving this 99:59:59.999 --> 99:59:59.999 building and this will take us probably the next 24 hours. So yeah, for the usual 99:59:59.999 --> 99:59:59.999 numbers. Edge capacity: this year because you didn't use all the Internet last year, 99:59:59.999 --> 99:59:59.999 we only brought you 300 gigs, but that was fine as well, I suppose. We got 100 gig 99:59:59.999 --> 99:59:59.999 from HLKomm here in Leipzig, 100 gig from Deutsche Telekom and as well as 100 gig 99:59:59.999 --> 99:59:59.999 from BCIX which we got via DWDM wave to Berlin. In the core we used Juniper 99:59:59.999 --> 99:59:59.999 MX960s, MX480s, MX204s and QFX10002 in the yolocolo. Basically all the halls were 99:59:59.999 --> 99:59:59.999 connected via a 200 gig link and yolocolo had three times 100 gig. As probably the 99:59:59.999 --> 99:59:59.999 last five or so years, we're using IS-IS and BGP for our protocols of choice. And 99:59:59.999 --> 99:59:59.999 this year we also first off rejected RPKI invalid routes and secondly applied for 99:59:59.999 --> 99:59:59.999 the first time at congress BCP38 ingress filtering to be a good internet citizen 99:59:59.999 --> 99:59:59.999 and not to allow you to spoof IP addresses. So yeah, that was nice. As 99:59:59.999 --> 99:59:59.999 Congress keeps on growing, we have 2500 tables somewhere around the building in 99:59:59.999 --> 99:59:59.999 all the assemblies, but we only have 300 switches. So sorry if you had to bring a 99:59:59.999 --> 99:59:59.999 long cable and if you have switches to spare with 10 gig uplinks and POE+, feel 99:59:59.999 --> 99:59:59.999 free to donate them to us. Access and Wi- Fi. We had like 300 access switches. We 99:59:59.999 --> 99:59:59.999 are obviously again running Aruba Wi-Fi controllers. This year, like at camp we 99:59:59.999 --> 99:59:59.999 had a few 802.1x access points, more on that later. We tried to use Juniper vMX to 99:59:59.999 --> 99:59:59.999 route the Wi-Fi traffic. And had quite a shitload of switches, most of them from 99:59:59.999 --> 99:59:59.999 Juniper, some Cisco 2960s, some Brocades which are new to us, and some crappy old 99:59:59.999 --> 99:59:59.999 HPE stuff which is basically configured for us to work like a brick you get from 99:59:59.999 --> 99:59:59.999 like eBay or whatnot. We had a few incidents this year we'd like to talk 99:59:59.999 --> 99:59:59.999 about. First off, we had, I'm not sure if any of you noticed, quite a lot of packet 99:59:59.999 --> 99:59:59.999 loss and missing router advertisements on the Wi-Fi. This was caused by some weird 99:59:59.999 --> 99:59:59.999 Juniper vMX behavior. We couldn't figure out what it was. So we had them running in 99:59:59.999 --> 99:59:59.999 a redundant VRRP setup. We shut down one of them and then it worked. So yeah, fuck 99:59:59.999 --> 99:59:59.999 redundancy. There was a pixelflut client which somehow messed up his IP address and 99:59:59.999 --> 99:59:59.999 caused a broadcast storm which took down most parts of Hall 2. We found them, shut 99:59:59.999 --> 99:59:59.999 it down and deployed storm control to all our access switches. Yeah, to the Congress 99:59:59.999 --> 99:59:59.999 motto resource exhaustion: someone was running aggressive zmap scanning over the 99:59:59.999 --> 99:59:59.999 whole internet, came by our Wi-Fi access controller and caused a state table 99:59:59.999 --> 99:59:59.999 exhaustion. And that brought it down. We null-routed the source and yeah, there was 99:59:59.999 --> 99:59:59.999 this issue. So thank you to whoever was that. And in the morning of day 3, we had 99:59:59.999 --> 99:59:59.999 another issue with Juniper vMX where it forgot it had a network card. We rebooted 99:59:59.999 --> 99:59:59.999 it and everything was fine again. So yeah, some numbers. You actually managed to use 99:59:59.999 --> 99:59:59.999 more bandwidth, thank you. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: But it's still only 20% of our uplink capacity. So use more. 20% of that was 99:59:59.999 --> 99:59:59.999 IPv6, which is good, but could be more. We had like 11000 clients into Wi-Fi. 86% 5 99:59:59.999 --> 99:59:59.999 GHz, 96% in a peak. We had eleven 802.11ax clients. Our 99:59:59.999 --> 99:59:59.999 favorite one was obviously the one with the lovely hostname ILOVETHENOC. So yeah, 99:59:59.999 --> 99:59:59.999 about that number we have, 96% 5 GHz obviously shows us that we are finally at 99:59:59.999 --> 99:59:59.999 the point where we can say: thank you 2.4 GHz, it was nice. Goodbye. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: Also, obviously, thank you to our sponsors. We couldn't do this if we would 99:59:59.999 --> 99:59:59.999 not get like 10 millions, of list price obviously, of equipment and loan and quite 99:59:59.999 --> 99:59:59.999 a lot of services. So give them a round of applause as well. Thank you. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: And obviously NOC not only stands for Network Operation Center, but if you 99:59:59.999 --> 99:59:59.999 extend it, it is No CO2. So we believe in green power and clean traffic and 99:59:59.999 --> 99:59:59.999 therefore we obviously see that sustainability is a great part of our 99:59:59.999 --> 99:59:59.999 role. This is why we even use old crappy HP switches to cut our lines for our 99:59:59.999 --> 99:59:59.999 tchunk to serve your cheese boards, whatever you need. 99:59:59.999 --> 99:59:59.999 *laughter* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: Also... [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: Also, we somehow estimated what our network will run us in CO2 and that was 99:59:59.999 --> 99:59:59.999 about 11 tons. We're not very good with mass and not very good with CO2 emissions, 99:59:59.999 --> 99:59:59.999 but this was roughly what we came up with. And to make Congress or the world a bit 99:59:59.999 --> 99:59:59.999 better place, we actually offset all our CO2 and bought eleven tons of CO2 99:59:59.999 --> 99:59:59.999 emissions. And now Frederick is gonna tell you how we got all those numbers. 99:59:59.999 --> 99:59:59.999 Frederick: Yeah, as a good internet manufacture, we also do monitoring a lot 99:59:59.999 --> 99:59:59.999 and we run our own Prometheus server inside. You probably know the dashboard 99:59:59.999 --> 99:59:59.999 that we propagate all over the internet and that's powered by Prometheus. We have 99:59:59.999 --> 99:59:59.999 an internal Grafana that is part of this whole ecosystem. And if you are a little 99:59:59.999 --> 99:59:59.999 bit of a nerd, you might have clicked on the dashboard sections and seen that there 99:59:59.999 --> 99:59:59.999 are more dashboards than this. We fill our Prometheus with lots of different sources: 99:59:59.999 --> 99:59:59.999 we get SNMP data from, and screw SNMP, but it does a quite good job at getting all 99:59:59.999 --> 99:59:59.999 the insights we need from all the network equipment. We have node_exporter, influx 99:59:59.999 --> 99:59:59.999 and all that, but we got a decent amount of data from everyone in the Congress 99:59:59.999 --> 99:59:59.999 ecosystem and we had that at camp as well where we got the water pressure of the 99:59:59.999 --> 99:59:59.999 showers. And we get the colo power, which also helps with estimating the CO2 99:59:59.999 --> 99:59:59.999 footprint. And everything is being configured by Netbox, which is a tool that 99:59:59.999 --> 99:59:59.999 is an asset database. And as I said, we have lots of dashboards and graphs. Of 99:59:59.999 --> 99:59:59.999 course, the public one where you can see lots of different things from everyone. 99:59:59.999 --> 99:59:59.999 This is only part of it. If you scroll down on the dashboard, you see a lot more. 99:59:59.999 --> 99:59:59.999 But this helps everyone to have a good understanding of what is happening 99:59:59.999 --> 99:59:59.999 currently. And we even draw a nice little Christmas trees on the Wi-Fi traffic for 99:59:59.999 --> 99:59:59.999 you. That is mostly because it's a router- on-a-stick and we cannot measure it 99:59:59.999 --> 99:59:59.999 correctly. We have an internal dashboard which gives us a little bit of a status 99:59:59.999 --> 99:59:59.999 for build-up mostly: which switches and routers are up? And that gives us a very 99:59:59.999 --> 99:59:59.999 quick sight of all the devices that are out there. What's broken? What's not 99:59:59.999 --> 99:59:59.999 broken? We improved it a little and now have alarms so someone can look at stuff 99:59:59.999 --> 99:59:59.999 and see if things are broken, run out there and fix it. We also built 99:59:59.999 --> 99:59:59.999 weathermaps. As you can see that's a little bit of a mess. But we couldn't do 99:59:59.999 --> 99:59:59.999 it better because the graphing library doesn't allow us to do it better. If 99:59:59.999 --> 99:59:59.999 someone has a good idea to do it better in Grafana or anywhere else with sources from 99:59:59.999 --> 99:59:59.999 Prometheus, please come to us, we're happy to talk. But this shows our core and all 99:59:59.999 --> 99:59:59.999 the links between it and how much capacity is being used. Red indicates that it's 99:59:59.999 --> 99:59:59.999 used more heavily. We also have that for the yolocolo. And all the traffic around 99:59:59.999 --> 99:59:59.999 it as well. And, yeah, teardown starts now. Please don't touch our equipment. And 99:59:59.999 --> 99:59:59.999 if you want to come and help, please come to Hall 4 and get in touch. We always need 99:59:59.999 --> 99:59:59.999 helping hands. But please in an organized way don't disassemble switches or access 99:59:59.999 --> 99:59:59.999 points. We have lists and everything. We need to account for everything. So please 99:59:59.999 --> 99:59:59.999 come to Hall 4 if you want to help. And yes, use more bandwidth and offset more 99:59:59.999 --> 99:59:59.999 CO2. Thank you. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: So thanks a lot. Actually, because you're clearly the backbone or one of 99:59:59.999 --> 99:59:59.999 those many backbones of the conference, is there any Q? Let's do a Q&A for like one 99:59:59.999 --> 99:59:59.999 or two questions. Is anyone having a question right now? 99:59:59.999 --> 99:59:59.999 Someone is standing up. Right, microphone number one, please. 99:59:59.999 --> 99:59:59.999 Q: Hey, we've absolutely don't ... [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Nearer, nearer. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Q: We've absolutely done bcp38 in previous years, by the way. 99:59:59.999 --> 99:59:59.999 M: Sorry for what I said then, I'm sorry. Q: So I wanted to correct the record. 99:59:59.999 --> 99:59:59.999 We've been good netizens in previous years as well. 99:59:59.999 --> 99:59:59.999 H: Oh, you're right. Thank you. Was there another question or something else to 99:59:59.999 --> 99:59:59.999 correct them? Because they clearly don't know what they're doing. 99:59:59.999 --> 99:59:59.999 *laughter* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Yeah. Feel free. Microphone number two. Q: So if 2.4GHz is over, what's going to 99:59:59.999 --> 99:59:59.999 happen to all of the ESP32 in various IoT devices? Are they going to have a home 99:59:59.999 --> 99:59:59.999 here next year? M: They'll definitely have a home. But as 99:59:59.999 --> 99:59:59.999 usual, we cannot support it as good as we can on 5GHz because obviously this band is 99:59:59.999 --> 99:59:59.999 overused and not even remotely suited for that amount of clients we put on it. 99:59:59.999 --> 99:59:59.999 Q: A follow-up for the ESP32. How exactly can you locate them through the wireless 99:59:59.999 --> 99:59:59.999 if they are lost? M: Well, we can't. We can basically look 99:59:59.999 --> 99:59:59.999 at which access point they are, and then if someone really would want to, we could 99:59:59.999 --> 99:59:59.999 start triangulation, but we've never done that before. So yeah, we can just pin them 99:59:59.999 --> 99:59:59.999 roughly to an access point. H: Maybe we can ask c3nav next time. So 99:59:59.999 --> 99:59:59.999 please give the NOC a hand. Thank you. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: So, the next team up is the POC. Do we have to click this? Use more bandwidth, 99:59:59.999 --> 99:59:59.999 I'm going to try. Ah! Thank you. Your stage. 99:59:59.999 --> 99:59:59.999 Garvin: Thanks. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Maria: Hi, my name is Maria. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 G: Hi, and I'm Garvin and we're from Phone Operation Center and we want to talk a bit 99:59:59.999 --> 99:59:59.999 about the phone infrastructure at this event. 99:59:59.999 --> 99:59:59.999 M: Yeah. So we arrived at day -6 and planned on hacking some things 99:59:59.999 --> 99:59:59.999 and socializing and we planned a team event, but then everything was different. 99:59:59.999 --> 99:59:59.999 G: Yeah. When we arrived, I went into the NOC office and they said to me, "Ja, CCL 99:59:59.999 --> 99:59:59.999 is up, internet is up, everything is just working nicely. You can start hook up your 99:59:59.999 --> 99:59:59.999 telephony system right now." And I was like, whoa. So thanks a lot NOC. Really 99:59:59.999 --> 99:59:59.999 great performance this year, we were amazed. Nobody expected that it works so 99:59:59.999 --> 99:59:59.999 well. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: Yeah. So we put up the first antennas and then we decided to have our team event 99:59:59.999 --> 99:59:59.999 anyway. And yeah, so we did a lot of things. So we handed out 150 orga loan 99:59:59.999 --> 99:59:59.999 DECTs and we deployed 51 SIP telephones. We also deployed 67 antennas and we had a 99:59:59.999 --> 99:59:59.999 POC party on day three until 7:30 a.m. G: So you can see almost everything is 99:59:59.999 --> 99:59:59.999 done. I guess the remaining things are not that important. So this is the overview of 99:59:59.999 --> 99:59:59.999 DECT coverage at the event. Only level zero, because otherwise I think it would 99:59:59.999 --> 99:59:59.999 be overcrowded to show. Just so that you can get a rough impression on how many 99:59:59.999 --> 99:59:59.999 antennas we deployed in order to give you this DECT coverage. That you can be 99:59:59.999 --> 99:59:59.999 reached almost everywhere in the event and that you can see how our tooling looks 99:59:59.999 --> 99:59:59.999 like, where we see how good the antennas see each other, and that we can see that 99:59:59.999 --> 99:59:59.999 seamless handover work so that you can start at our desk, walk through the area, 99:59:59.999 --> 99:59:59.999 into the lounge and just continue talking. And oh, there are also some antennas that 99:59:59.999 --> 99:59:59.999 are outside of the building. What could that be? 99:59:59.999 --> 99:59:59.999 M: That is our hotel DECT. And you can see a typical hotel DECT installation on the 99:59:59.999 --> 99:59:59.999 photo. And people got really confused about it because we also had DECT coverage 99:59:59.999 --> 99:59:59.999 at main station. G: Yeah. So I got a call roughly at 4:00 99:59:59.999 --> 99:59:59.999 p.m. in the morning. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 G: And somebody told me. Oh, my DECT rang. Why? Now I need to turn it off at the 99:59:59.999 --> 99:59:59.999 night. Why did you do this? M: Yeah. So we also had problems. We have 99:59:59.999 --> 99:59:59.999 a new feature since Camp where you can see your DECT devices and can assign them to 99:59:59.999 --> 99:59:59.999 your number before you even arrive, and then everything is set up and you don't 99:59:59.999 --> 99:59:59.999 have to call your token anymore. And people get really confused because they 99:59:59.999 --> 99:59:59.999 would call their token anyway and it calls it invalid. So we had to explain a lot of 99:59:59.999 --> 99:59:59.999 this unexpected simplicity to them. G: And then we had a battery issue this 99:59:59.999 --> 99:59:59.999 year. We had not enough batteries and, you know, batteries are always empty in the 99:59:59.999 --> 99:59:59.999 phones when it's the most important. So we were thinking what what can we do about 99:59:59.999 --> 99:59:59.999 that? M: So we build a new device. That's our 99:59:59.999 --> 99:59:59.999 microwave and it can also charge devices. So, many thanks to C3Power, because they 99:59:59.999 --> 99:59:59.999 helped us with tooling and actually they have expertise to put power cables on 99:59:59.999 --> 99:59:59.999 devices like this. Thank you very much. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 G: In the last years we were often asked "how expensive is your service actually?". 99:59:59.999 --> 99:59:59.999 So we decided that we now provide invoices so you can see how expensive our services 99:59:59.999 --> 99:59:59.999 are and we send out a lot of invoices. And we got paid some money. But as you can see 99:59:59.999 --> 99:59:59.999 on the invoices, most is sponsored by CCC. M: Yeah. And people also paid with Mate 99:59:59.999 --> 99:59:59.999 which is really awesome. G: Yeah. And also people have invoices on 99:59:59.999 --> 99:59:59.999 a fraction of a cent and they got quite creative on how they can pay us. 99:59:59.999 --> 99:59:59.999 *laughter* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: So here are some more stats. We have 7473 registered extensions. 99:59:59.999 --> 99:59:59.999 G: Oh, we didn't remove this. So we were thinking on how to compare this with 99:59:59.999 --> 99:59:59.999 things and we were looking at villages in Saarland and then we thought, this is a 99:59:59.999 --> 99:59:59.999 stupid comparison, but we didn't remove this. 99:59:59.999 --> 99:59:59.999 M: So there were 5021 attached DECT phones and 3251 concurrent DECT phones. Which is 99:59:59.999 --> 99:59:59.999 about more than 1000 more than last year. G: So thanks a lot for using DECT. 99:59:59.999 --> 99:59:59.999 M: Yeah. We had... [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: There were also max 120 calls in parallel, and we had more than 300 99:59:59.999 --> 99:59:59.999 thousand calls in total. That's also really, really much. We had five eating 99:59:59.999 --> 99:59:59.999 meetings at heaven, the angel eating place, and there were an average of 42 99:59:59.999 --> 99:59:59.999 eating meeting live viewers. We had two lectures. You can see them on media.ccc.de 99:59:59.999 --> 99:59:59.999 and we had 23 super fast charged phones in our microwave. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 G: Like the NOC, we also had to deal a bit with issues during the event, and actually 99:59:59.999 --> 99:59:59.999 there were some DDOS attack on our account system and somebody configured over 4000 99:59:59.999 --> 99:59:59.999 extensions with really stupid names. And it took us quite a while to get rid of 99:59:59.999 --> 99:59:59.999 them again cleanly from the system because the synchronization turned out to be 99:59:59.999 --> 99:59:59.999 really slow. So you can see it took us a while to get them removed again. So we can 99:59:59.999 --> 99:59:59.999 only say, you all know it's a hacker congress, but it's kind of stupid to hack 99:59:59.999 --> 99:59:59.999 your own infrastructure. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 G: So as a consequence of this, we only allow now only 50 extensions per account 99:59:59.999 --> 99:59:59.999 and per event. If you think you need more, feel free to contact us if you have a 99:59:59.999 --> 99:59:59.999 valid use case. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: So every device has an IPEI that is like a MAC address and we ask the 99:59:59.999 --> 99:59:59.999 responsible institution to give us the manufacturer. But it's really secret. So 99:59:59.999 --> 99:59:59.999 they don't give it to us. So we ask you for help. Please enter the models of your 99:59:59.999 --> 99:59:59.999 devices for your phones. And then we can match to the IPEI and get some data to 99:59:59.999 --> 99:59:59.999 build more awesome features for you. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 G: This would really help us. And the only way for us is to crowdsource it because it 99:59:59.999 --> 99:59:59.999 seems to be super secret. Whatever. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: You can find it in guru3 on the device page and there's this little pen. And if 99:59:59.999 --> 99:59:59.999 you click on it, then you can enter the model. 99:59:59.999 --> 99:59:59.999 G: Thanks upfront. And yep, that's from us, and I guess now we have a little time 99:59:59.999 --> 99:59:59.999 for you to ask questions. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Great. So, any questions for the POC? I don't see... were they correct or do we 99:59:59.999 --> 99:59:59.999 have to...? Ah, someone is getting up. So microphone number 1, please. 99:59:59.999 --> 99:59:59.999 Q: Yes, a few years ago there was a translation service via DECT. Is the 99:59:59.999 --> 99:59:59.999 capacity enough to service also this crowd? 99:59:59.999 --> 99:59:59.999 G: The problem is that we switched the phone system a while ago last year at the 99:59:59.999 --> 99:59:59.999 Congress. And the old phone system had a way how we can do the translation via one 99:59:59.999 --> 99:59:59.999 channel and the problem is that the new system doesn't support this. Let me say 99:59:59.999 --> 99:59:59.999 the new system doesn't support it yet. So have a look at our talk and then you can 99:59:59.999 --> 99:59:59.999 see that there is some potential. H: I see someone at microphone number 3, 99:59:59.999 --> 99:59:59.999 please. This would be the last question because we have to hurry a bit. 99:59:59.999 --> 99:59:59.999 Q: Can I know a little bit more about the super charging microwave? I'm confused. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 M: Sure, you can come to our POC desk and then we answer all your questions. 99:59:59.999 --> 99:59:59.999 H: Ooh... mystery. Please, give the POC a hand. 99:59:59.999 --> 99:59:59.999 So next team, is it from the GSM crew? Someone there? I think we have two. I see 99:59:59.999 --> 99:59:59.999 some Chaos Post, you have to wait one round. So, GSM guy thank you. I am good 99:59:59.999 --> 99:59:59.999 with computers, I think. Yeah, I am. Have fun. If it's working or not. Look at this 99:59:59.999 --> 99:59:59.999 smile then looks better. Try this. Yeah. Right. Try this. 99:59:59.999 --> 99:59:59.999 - 423. - Maybe you have to use GSM. 99:59:59.999 --> 99:59:59.999 - 23 test. - What happened? 99:59:59.999 --> 99:59:59.999 - Hello. Hello. - Aah. 99:59:59.999 --> 99:59:59.999 GSM Person 1: So as every year we ran our own mobile phone network at the Congress 99:59:59.999 --> 99:59:59.999 using osmocom open source software for 2G and 3G, and open5gs interfacing with the 99:59:59.999 --> 99:59:59.999 osmocom HLR. And all you need to take part is a SIM card that you can buy from the 99:59:59.999 --> 99:59:59.999 POC and for 5 euros you get a flat rate. The price increases because we have less 99:59:59.999 --> 99:59:59.999 SIM cards every year. We need to manufacture new ones. You can even call 99:59:59.999 --> 99:59:59.999 outside like you can with DECT phones. Lynxis: Hello. I'm Lynxis. So as every 99:59:59.999 --> 99:59:59.999 year for the GSM team, the first problem is the license. That's the first step 99:59:59.999 --> 99:59:59.999 usually. Because in Germany, you have to get the official form, get a license but 99:59:59.999 --> 99:59:59.999 ... Where do you get it? What can you ask for frequencies? Because, for example, the 99:59:59.999 --> 99:59:59.999 POC for DECT or Wi-Fi, you just place it and you can use it. You're fine. 99:59:59.999 --> 99:59:59.999 But for GSM, they didn't think about it or for 3G or 4G. So yeah, this year we 99:59:59.999 --> 99:59:59.999 usually get the license middle of december, maybe start of december. So it's 99:59:59.999 --> 99:59:59.999 already late. So this year we didn't get all our licenses. But we get some. We got 99:59:59.999 --> 99:59:59.999 850 MHz, which is not assigned in Europe because it's usually in the US only. But 99:59:59.999 --> 99:59:59.999 we have a small hole. This year we got a 4G license instead of a 2G license with 10 99:59:59.999 --> 99:59:59.999 Mhz from Telefonica. So thanks Telefonica for borrowing us spectrum. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 L: Just a short example of how the spectrum looks like. The yellow stuff is 99:59:59.999 --> 99:59:59.999 usually somewhere behind actually. By the way, this microphone, it might share the 99:59:59.999 --> 99:59:59.999 same frequency with us. But so far, we haven't found any interference together 99:59:59.999 --> 99:59:59.999 with the VOC. Down there you can see the small hole which we are using. Because we 99:59:59.999 --> 99:59:59.999 didn't get the 2G license there, we thought, OK. Let's take a look. Can we fit 99:59:59.999 --> 99:59:59.999 them both in the same frequencies? It's not good. But you see the spikes, this 99:59:59.999 --> 99:59:59.999 nice antenna on the right. That's the GSM, which is sending on the same frequency. It 99:59:59.999 --> 99:59:59.999 works because they are using different codings. But I have heard from people who 99:59:59.999 --> 99:59:59.999 know more about it, this is not the way you use it. 99:59:59.999 --> 99:59:59.999 *laughing* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 L: So we took some photos of our base stations. This is actually the fairy dust 99:59:59.999 --> 99:59:59.999 from the 2G base station, so we have a idea what we are using here. We have even 99:59:59.999 --> 99:59:59.999 more fairy dust in our 3G femtocells and our 4G cells. They are looking like small 99:59:59.999 --> 99:59:59.999 toasters. They are taking actually 90 watts via POE, they have special POE 99:59:59.999 --> 99:59:59.999 adapters. So maybe we could ask if somebody can do a similar adapter to get 99:59:59.999 --> 99:59:59.999 even running a toaster on the line. So basically for the 4G setup this year, 99:59:59.999 --> 99:59:59.999 we weren't sure if it's stable enough or we lose all our phones to the LTE and they 99:59:59.999 --> 99:59:59.999 don't like to come back to the 2G and 3G setup where we have voice, because on LTE 99:59:59.999 --> 99:59:59.999 we don't have yet voice so you have to select specifically to join the LTE 99:59:59.999 --> 99:59:59.999 network. That worked quite fine if you change it. So your phone will register. 99:59:59.999 --> 99:59:59.999 Everything fine there. GSM1: So the rollout this year: we had the 99:59:59.999 --> 99:59:59.999 voice working on day 0 which is new. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 GSM1: Someone even noticed on Mastodon, I saw it, too. We already had LTE at the CCC 99:59:59.999 --> 99:59:59.999 camp this year. Yeah, but unfortunately we lost crypto password, so LTE roll out took 99:59:59.999 --> 99:59:59.999 a bit longer this time. Sorry. So some numbers. In total we saw just about 1100 99:59:59.999 --> 99:59:59.999 people doing a location updating on our network and 845 eventphone tokens were 99:59:59.999 --> 99:59:59.999 dialed on the GSM. That is 2G or 3G. And there were roughly 200 phones actively 99:59:59.999 --> 99:59:59.999 subscribed on the network at all times. And even though we basically only deployed 99:59:59.999 --> 99:59:59.999 3G nano stations in all the halls and only had two 2G BTS in the glass halle, there 99:59:59.999 --> 99:59:59.999 were roughly more than half of all the phones were still subscribed on 2G instead 99:59:59.999 --> 99:59:59.999 of 3G. We had like 18 3G stations and only two plus one in the GSM room 2G stations. 99:59:59.999 --> 99:59:59.999 So that's a bit surprising. And SIM cards: starting from the bottom, we sold about 99:59:59.999 --> 99:59:59.999 700 SIM cards, but only saw half of them activated, which is curious. And luckily, 99:59:59.999 --> 99:59:59.999 most or some people bring old SIM cards from previous years. And it's not so easy 99:59:59.999 --> 99:59:59.999 to get cards manufactured. So we are very glad for everyone who brings old SIM cards 99:59:59.999 --> 99:59:59.999 from previous events. We might even consider introducing charging phone calls 99:59:59.999 --> 99:59:59.999 only for SIM cards that are newly bought. So if you want to continue calling for 99:59:59.999 --> 99:59:59.999 free, rather bring your old SIM cards. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 GSM1: So you see the numbers, I'm not going to go through them. And you can also 99:59:59.999 --> 99:59:59.999 get the ADM, the admin keys for your SIM cards if you like to write to them. 99:59:59.999 --> 99:59:59.999 L: Or if you have seen the talk from LaForge, you might want to play with the 99:59:59.999 --> 99:59:59.999 SIM cards, we give out all the keys you want to have to play with it. 99:59:59.999 --> 99:59:59.999 GSM1: So operation was mostly smooth, except iPhones, for unknown reasons. And 99:59:59.999 --> 99:59:59.999 except the data service, which might even be related because maybe Apple is a bit 99:59:59.999 --> 99:59:59.999 more strict on whether data service is working reliably. Yeah, we still had some 99:59:59.999 --> 99:59:59.999 problems in the SGs instance introducing 3G changing between the radio access 99:59:59.999 --> 99:59:59.999 technologies. It's a whole new ballgame so there are still some bugs in there. And as 99:59:59.999 --> 99:59:59.999 you see, we had many more tickets than the POC. This is actually reversed from the 99:59:59.999 --> 99:59:59.999 POC, the "done" is on the left. So this whole bunch of stuff is done and there's 99:59:59.999 --> 99:59:59.999 some backlog and canceled and fantasy tasks. It worked pretty nicely. Are you 99:59:59.999 --> 99:59:59.999 taking over? Oh, yeah, no, this is still mine. And this year we actually had also a 99:59:59.999 --> 99:59:59.999 denial of service attack. The code was the same as previous years and we never saw 99:59:59.999 --> 99:59:59.999 this before. But this year we got an invalid mobile identity which managed to 99:59:59.999 --> 99:59:59.999 crash our mobile switching center. And thank you very much for uncovering this 99:59:59.999 --> 99:59:59.999 bug and thanks to fixeria for fixing it on day 2. Ever since the mobile switching 99:59:59.999 --> 99:59:59.999 center for Voice and SMS and subscription has been running stable. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 L: Maybe some interference. We recovered the old phones again. Last year we 99:59:59.999 --> 99:59:59.999 couldn't support them. But we managed to implement the missing parts. Old phones 99:59:59.999 --> 99:59:59.999 could work if they support the frequencies. So that's really nice. Maybe 99:59:59.999 --> 99:59:59.999 next time. Since camp, we also did a nice angel helpdesk. And it was really 99:59:59.999 --> 99:59:59.999 impressive to see that we even had to add more shifts in our shifts. We had so many 99:59:59.999 --> 99:59:59.999 motivated angels. Thanks to everybody who helped us, it was really great. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Unfortunately, we don't have enough time for a Q&A. So please give them a hand 99:59:59.999 --> 99:59:59.999 for everything they did. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Thank you. There are quite a lot of teams next. I count at least like eight, 99:59:59.999 --> 99:59:59.999 maybe nine. So we need to speed up a bit. Our next team for now will be... We don't 99:59:59.999 --> 99:59:59.999 have working microphones. Chaos post 1: Sorry, we need to interrupt 99:59:59.999 --> 99:59:59.999 you anyway. H: OK. So tell them, chaos post! Chaos 99:59:59.999 --> 99:59:59.999 post! [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Chaos post 1: Sorry, guys, we interrupt... [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Let's get rid of the broken one because it's not working anyway. 99:59:59.999 --> 99:59:59.999 Chaos post 1: All right. Sorry, we are interrupting for a few minutes only. We 99:59:59.999 --> 99:59:59.999 would like to deliver a few statistics as well. So thanks of all, we had multiple 99:59:59.999 --> 99:59:59.999 chaos deliverers working throughout the whole Congress 24/7 basically, delivering 99:59:59.999 --> 99:59:59.999 at the speed of chaos, as our mission statement clearly states. So thank you 99:59:59.999 --> 99:59:59.999 therefore, first of all thank you very much to all of you who contributed to 99:59:59.999 --> 99:59:59.999 that. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Chaos post 2: So let's have some numbers, because you all love numbers, right? So we 99:59:59.999 --> 99:59:59.999 delivered about 3000 external postcards. So that means with like outside chaos, so 99:59:59.999 --> 99:59:59.999 to the real world or the default world, as we call it. We delivered those to over 42 99:59:59.999 --> 99:59:59.999 countries all over the world. So you guys are really good connected internationally. 99:59:59.999 --> 99:59:59.999 And also, we don't have exact numbers, but we estimate around 3500, no, 35000, 99:59:59.999 --> 99:59:59.999 internal postcards. And you also use our online office for a total of 789 times. So 99:59:59.999 --> 99:59:59.999 that is only 15 less than camp, and that was a longer event. So, hey, you guys 99:59:59.999 --> 99:59:59.999 write a lot of postcards! [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Chaos post 1: As you might already know from camp, we also do have a few special 99:59:59.999 --> 99:59:59.999 services. As already on camp, we had the serving proposal, basically a pre- 99:59:59.999 --> 99:59:59.999 assembled text, you just had to cross what you want. The postbox certification and of 99:59:59.999 --> 99:59:59.999 course, the bi-directional chaos, in Germany also known as "Einschreiben mit 99:59:59.999 --> 99:59:59.999 Rückschein". H: Wow. 99:59:59.999 --> 99:59:59.999 Chaos post 2: And this time we also offered some new services. We had like 99:59:59.999 --> 99:59:59.999 sang telegrams, gesunges Telegram in Deutsch. We had a forever alone box for 99:59:59.999 --> 99:59:59.999 people wanting to write postcards with or exchange postcards with no idea who to 99:59:59.999 --> 99:59:59.999 write it to. We had love letters, so we had some nice pre-assembled texts and also 99:59:59.999 --> 99:59:59.999 a really nice selection of perfumes for scented postcards. You could write some 99:59:59.999 --> 99:59:59.999 secret messages. We had some UV pens and also we had some, let's say call it 99:59:59.999 --> 99:59:59.999 security, or rather temper evidence, because we had some scratch off stickers 99:59:59.999 --> 99:59:59.999 for you. And also we had over 30 new postcard designs that you could use for 99:59:59.999 --> 99:59:59.999 postcards. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Chaos post 1: Short remark for the love letters and the perfumes. Well, that was 99:59:59.999 --> 99:59:59.999 kind of not really thought through. It was a bit... it was fun sorting them out, and 99:59:59.999 --> 99:59:59.999 stamping all of that, smelling all the perfume all the time. 99:59:59.999 --> 99:59:59.999 Chaos post 2: And then brushing your hands really thoroughly because, well, that 99:59:59.999 --> 99:59:59.999 stuff gets on your hands when you do that. Chaos post 1: Also for UV pens. Just a 99:59:59.999 --> 99:59:59.999 little remark. It's not a good idea to use it for addressing and the message. 99:59:59.999 --> 99:59:59.999 *laughing* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Chaos post 1: You can take the risk. All right, then let me close up. We also 99:59:59.999 --> 99:59:59.999 supported mail this year and we had 130 letters for activists in 99:59:59.999 --> 99:59:59.999 prison, which I find really great. I think that's something we can all support. 99:59:59.999 --> 99:59:59.999 Amazing. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 So thank you all for this amazing event, and have some fun for the rest of the 99:59:59.999 --> 99:59:59.999 Congress. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Chaos post! So the next team is the VOC. Yes, you can have it. Here, the VOC. 99:59:59.999 --> 99:59:59.999 We only have 20 minutes left in total for every team. So you know what to do. 99:59:59.999 --> 99:59:59.999 VOC1: Hurry up. Welcome, guys. So. Yeah. We don't have as many statistics as usual. 99:59:59.999 --> 99:59:59.999 But we have some great stories too. We'll hurry up. So this year in total, we 99:59:59.999 --> 99:59:59.999 covered 10 stages apart from the 5 stages that we do usually for Congress. We had 99:59:59.999 --> 99:59:59.999 streams from the critical decentralisation cluster, Sendezentrum, Wikipaka WG, Open 99:59:59.999 --> 99:59:59.999 Infrastructure Orbit, Chaos West. And in total, we served 255 hours and 35 minutes 99:59:59.999 --> 99:59:59.999 of total talk time. So you know what to do until the next Congress. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 VOC1: And of course, sustainability was a big topic during this Congress. So part of 99:59:59.999 --> 99:59:59.999 what we have to do is stream reencoding so you can watch it with the VP5 codec or use 99:59:59.999 --> 99:59:59.999 it at lower resolution. And so far we've been using 4 Xeon-based machines and 2 99:59:59.999 --> 99:59:59.999 desktop machines. And thanks to hardware- based encoding, we now replace this with a 99:59:59.999 --> 99:59:59.999 single laptop. As you can maybe read, this is critical infrastructure now. And for 99:59:59.999 --> 99:59:59.999 all the streams, for 30 reencoding streams, we are on a 45 watt power budget 99:59:59.999 --> 99:59:59.999 now. And as an added benefit, because we also encode the master slides with 99:59:59.999 --> 99:59:59.999 hardware encoders, and hardware encoders can generally use a higher profile that 99:59:59.999 --> 99:59:59.999 allows for better quality in real time, you now get a better picture as well. So, 99:59:59.999 --> 99:59:59.999 yeah. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 VOC1: And of course, we had some minor fuckups this year. We thought the audio 99:59:59.999 --> 99:59:59.999 setup was a bit less complex. But when we checked rooms, we had buzzing everywhere. 99:59:59.999 --> 99:59:59.999 So we replaced some SDI lines with fiber and turns out buzzing goes away. Then the 99:59:59.999 --> 99:59:59.999 PA sound console had a buggy DANTE card. After you reboot them, the auxiliary out 99:59:59.999 --> 99:59:59.999 to the VOC cameras was muted. So that messed up the particular talk that has 99:59:59.999 --> 99:59:59.999 been redone today, but other than that, we are rather happy. And we figured that 3 of 99:59:59.999 --> 99:59:59.999 our audio mixers actually had broken outputs. I don't know how we did that, but 99:59:59.999 --> 99:59:59.999 it clearly shows that they've been used on one event or another during the last 99:59:59.999 --> 99:59:59.999 years, which is actually a good thing we may think. On the Wikipaka stage, we did 99:59:59.999 --> 99:59:59.999 not use Ansible because there was sort of a playground for us. But if you don't do 99:59:59.999 --> 99:59:59.999 things properly, well, then you run into edge cases with things. And yeah. So I 99:59:59.999 --> 99:59:59.999 need to hurry up. And one virtualization host suddenly started leaking memory. And 99:59:59.999 --> 99:59:59.999 so if you were affected by that during the main talk season in the evening, we are 99:59:59.999 --> 99:59:59.999 very sorry about that. Updating the kernel helped and we have no idea what happened. 99:59:59.999 --> 99:59:59.999 Yeah, and Icecast got stuck as well. And some relive... so if you want to see talks 99:59:59.999 --> 99:59:59.999 later, that may not be possible because we ran temporarily out of space. But if you 99:59:59.999 --> 99:59:59.999 watch this on media.ccc.de, and the talks were not yet released, we have relive 99:59:59.999 --> 99:59:59.999 integration, so the talks show up in media.ccc.de even though there is no 99:59:59.999 --> 99:59:59.999 proper release yet, for your convenience. And main track and assemblies are now 99:59:59.999 --> 99:59:59.999 integrated in all events, so you don't have to click through 4 separate events to 99:59:59.999 --> 99:59:59.999 find your favorite talk. And now I pass to Pat to talk about VOCTOMIX 2. 99:59:59.999 --> 99:59:59.999 Pat: Yeah. Thank you. Okay. I have now 20 seconds, I think. I made a redesign of 99:59:59.999 --> 99:59:59.999 VOCTOMIX, it's now called VOC2MIX. And Peter was doing that meme some weeks ago, 99:59:59.999 --> 99:59:59.999 because we had to switch to VOCTOMIX 2 and we wanted to try it in 2 rooms. And in the 99:59:59.999 --> 99:59:59.999 night from day 0 to 1 we decided to do it for every stage because the old solution 99:59:59.999 --> 99:59:59.999 was not working anymore. That was a little bit hot, but it worked. And, the redesign 99:59:59.999 --> 99:59:59.999 caused the new UI, complete with some new base features. We have now transitions 99:59:59.999 --> 99:59:59.999 where pictures are moving, and we have insertions for blending text into the 99:59:59.999 --> 99:59:59.999 picture and we have a new audio mixing and we are now proper A/V Sync in every case, 99:59:59.999 --> 99:59:59.999 I think. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Pat: And some mixer angels were exploring the software and they found some bonus 99:59:59.999 --> 99:59:59.999 features like random video distortion in some cases, which I have to fix, I think. 99:59:59.999 --> 99:59:59.999 And the party mode where you click some buttons and they are clicking without any 99:59:59.999 --> 99:59:59.999 doing of the user and everything is flickering and they called it party mode. 99:59:59.999 --> 99:59:59.999 This is what the current pipeline looks like. We have now over 200 gstreamer 99:59:59.999 --> 99:59:59.999 elements doing all this stuff to get your pictures, which you are having on the 99:59:59.999 --> 99:59:59.999 stream and in the recordings. That's it. VOC1: So, of course, there were some 99:59:59.999 --> 99:59:59.999 issues. I mean VOCTOMIX2 is essentially a rewrite. 99:59:59.999 --> 99:59:59.999 H: You have to speed up a bit. Actually we are stealing time from the other teams. I 99:59:59.999 --> 99:59:59.999 might call it a quit. VOC1: OK OK OK. So... 99:59:59.999 --> 99:59:59.999 H: Pressure! VOC1: Yes, I know. But you're not making 99:59:59.999 --> 99:59:59.999 things better. So one thing to mention: we had to deploy a sweaty finger fix after 99:59:59.999 --> 99:59:59.999 the first talk started. Ok, here are your stats, read them now, read them read them 99:59:59.999 --> 99:59:59.999 read them! [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Please give VOC a hand. Thank you. So what's next? Oh, the Stage manager and 99:59:59.999 --> 99:59:59.999 Herald Operation Center. I'm part of it. And we have 36 heralds, every one of them 99:59:59.999 --> 99:59:59.999 very eloquent and good-looking. Then we have 70 stage managers and stage 99:59:59.999 --> 99:59:59.999 supporters. We had 150 shows on official stages and the assemblies on top of it. We 99:59:59.999 --> 99:59:59.999 have one stage fright council yet for the speakers who took care of at least six 99:59:59.999 --> 99:59:59.999 talks. And then we threw away over 100 hosting cards on day 1 only. So clearly, 99:59:59.999 --> 99:59:59.999 give a hand for the SHOC. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: So next, c3power. Your time. Arif: So my name is Arif Guy. I am from 99:59:59.999 --> 99:59:59.999 the power team and from the radio operation center. We make the power. We 99:59:59.999 --> 99:59:59.999 load five double trucks of shit out on Sunday 15th. We deploy a lot of power 99:59:59.999 --> 99:59:59.999 boxes and many cables. So we have teardown today so every help is needed. We have 99:59:59.999 --> 99:59:59.999 only one day to bring us back. The main thing, we had the power meter that we made 99:59:59.999 --> 99:59:59.999 on the camp this year. We have two nice setup on room H. You see the power factor 99:59:59.999 --> 99:59:59.999 is very bad. And the other one was the Waffle Operation Center so you see they 99:59:59.999 --> 99:59:59.999 have a nice power factor. So please use more ohmic devices like heaters, waffle 99:59:59.999 --> 99:59:59.999 iron or something. We only have 5 Seaview to monitor Yolocolo. You have on 99:59:59.999 --> 99:59:59.999 c3power.top a Grafana link that also links to the main Grafana to the NOC. Another 99:59:59.999 --> 99:59:59.999 nice thing we have on the lounge, I have a video here. It started now. You can see 99:59:59.999 --> 99:59:59.999 the current on all 3 phases to the audio and you can see the audio from the lounge. 99:59:59.999 --> 99:59:59.999 *recorded music from the lounge* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Arif: It's very nice. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *recorded music from the lounge* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Arif: As you see, the only thing is... [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Arif: Use more bass, or make more current. Later we can show you another slide. Go to 99:59:59.999 --> 99:59:59.999 next slide please. So for the radio team we have 120 portable radios. We have 99:59:59.999 --> 99:59:59.999 updated them to a new firmware, and a new programming software with a new feature 99:59:59.999 --> 99:59:59.999 that is a lot slower than the last version. Very nice. 50 bring-your-own- 99:59:59.999 --> 99:59:59.999 device radios. 5 dead radios from the camp. 2 dead from 36c3. 2 dead repeaters 99:59:59.999 --> 99:59:59.999 from the camp. 1 dead on arrival on this stage. 3 rental repeaters from 2 99:59:59.999 --> 99:59:59.999 companies, one we picked up in Hannover just before the Congress, and even the 99:59:59.999 --> 99:59:59.999 windows PC crashed down dead on arrival. Business as usual. So, next team! 99:59:59.999 --> 99:59:59.999 H: Thank you! So, the next is c3subtitles. I think it's Amy and Julia. Amy. They are 99:59:59.999 --> 99:59:59.999 not. C3SOS. S.O.S. It's you. Okay. Okay. Sorry. Oh, I'm sorry. Not the subtitles. 99:59:59.999 --> 99:59:59.999 It's well, sustainability. Your stage, go for it. Here, feel free. 99:59:59.999 --> 99:59:59.999 Amy: Hello. Okay, hi. My name is Amy, I'm part of the c3sustainability team. I only 99:59:59.999 --> 99:59:59.999 have four slides, so I'll be very quick. You can see, the first of our biggest 99:59:59.999 --> 99:59:59.999 projects was the drinking water dispensers. So for angels, we had drinking 99:59:59.999 --> 99:59:59.999 water from a dispenser rather than from bottles and they could refill their 99:59:59.999 --> 99:59:59.999 bottles. We go through some stats there. So when we started planning how difficult 99:59:59.999 --> 99:59:59.999 it was to implement it, the locations, and how many volunteers, satisfaction was very 99:59:59.999 --> 99:59:59.999 high for this one. So thank you to c3geld who really helped organize the water 99:59:59.999 --> 99:59:59.999 dispensers with us. We're very happy. They were really great. Please give them a 99:59:59.999 --> 99:59:59.999 round of applause. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Amy: Thank you. The next one was a give and take electronic box. So we wanted to 99:59:59.999 --> 99:59:59.999 encourage people not to throw away their electronics. Of course, they can be 99:59:59.999 --> 99:59:59.999 recycled. So we have deployed 10 boxes. You can find them in the sticker stations. 99:59:59.999 --> 99:59:59.999 And we did this in collaboration with the hardware hacking area. Thank you. And 99:59:59.999 --> 99:59:59.999 other assemblies. Oh, wow, you are really fast. 99:59:59.999 --> 99:59:59.999 H: Yes I am. Amy: Okay! 99:59:59.999 --> 99:59:59.999 H: Others are waiting! Amy: Okay. So the last one I wanted to go 99:59:59.999 --> 99:59:59.999 through. We have two initiatives on this one. I'm sorry for the trashy picture 99:59:59.999 --> 99:59:59.999 there. We have organic bins in the halls. It was very, very difficult to do this. 99:59:59.999 --> 99:59:59.999 But actually it was quite satisfactory. But I would say there is room for 99:59:59.999 --> 99:59:59.999 improvement there. And there was also an initiative for recycling cigaret butts. So 99:59:59.999 --> 99:59:59.999 we actually had two people go round, collect your cigaret butts and they will 99:59:59.999 --> 99:59:59.999 be recycled into cool ashtrays. What a success! Thank you so much to everyone who 99:59:59.999 --> 99:59:59.999 collaborated with us. We couldn't do out without your help. 99:59:59.999 --> 99:59:59.999 H: Thank you. Your applause, please. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: So unfortunately, the c3sign is not coming. So just take a look at those 99:59:59.999 --> 99:59:59.999 pictures while I go through them. And now the next one is C3 Assemblies. Here, take 99:59:59.999 --> 99:59:59.999 this one. Thank you. Be quick. Pingu: Hi, my name is Pingu. I'm here for 99:59:59.999 --> 99:59:59.999 the assembly team. And I just want to ask, give a hand who hasn't found his assembly 99:59:59.999 --> 99:59:59.999 on day zero or day one? So then give a big applause to c3nav because they really 99:59:59.999 --> 99:59:59.999 helped us a lot. Because without them, it wasn't able to do this event just for us. 99:59:59.999 --> 99:59:59.999 Because for some figures we had 419 assemblies to place on this area which is 99:59:59.999 --> 99:59:59.999 about 35000 square meters. We had 3000 tables all over, 2500 in the assemblies, 99:59:59.999 --> 99:59:59.999 with 6000 chairs. And here, please give a big applause to the C3Möbelhaus or IKEA as 99:59:59.999 --> 99:59:59.999 you call it. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 Pingu: Because the Möbelhaus basically placed all the tables in a magic night on 99:59:59.999 --> 99:59:59.999 basically day -2. And they will disappear with the help of C3Möbelhaus today. We 99:59:59.999 --> 99:59:59.999 assigned the last assembly on day zero at 22:00 and we started our work in mid- 99:59:59.999 --> 99:59:59.999 October with weekly meetings. And yeah, as you can see, it was a lot of work and... 99:59:59.999 --> 99:59:59.999 Oh. H: Thank you. 99:59:59.999 --> 99:59:59.999 Pingu: Thank you. And just one thing, for teardown, for tearing down the assemblies, 99:59:59.999 --> 99:59:59.999 please stack the chairs on the assembly but leave every chair and every table on 99:59:59.999 --> 99:59:59.999 the assembly, we will get rid of them. H: Thanks a lot. Your applause. So the 99:59:59.999 --> 99:59:59.999 next ones are... Les prochains, ce sont les gens de c3lingo, voilà, vos tours! 99:59:59.999 --> 99:59:59.999 c3lingo 1: Hallo! Schön euch mal (...) Wir sind übersetzet. (...) 99:59:59.999 --> 99:59:59.999 German> Oh, sorry. Well, I'm also fine with that. 99:59:59.999 --> 99:59:59.999 We translated all the German talks into English. All the English talks into 99:59:59.999 --> 99:59:59.999 German. All in all, fifteen thousand minutes in seven different target 99:59:59.999 --> 99:59:59.999 languages. And here is from the second language team, who talk all the non- 99:59:59.999 --> 99:59:59.999 English and non-German things. c3lingo 2: Okay. So basically we did have 99:59:59.999 --> 99:59:59.999 about 1/3 of the talks were translated to French. Yeah. You can read the rest. And 99:59:59.999 --> 99:59:59.999 we even have currently, exactly, right now, another one which is translated into 99:59:59.999 --> 99:59:59.999 Swabian. So if you want to listen into it. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 c3lingo 2: Which means that if you were listening to a talk, there is 2 chance out 99:59:59.999 --> 99:59:59.999 of 3 that it was translated not only once, but twice. Into either French, Spanish, 99:59:59.999 --> 99:59:59.999 Russian, or Polish. One special mention for the Russian and Polish teams, that was 99:59:59.999 --> 99:59:59.999 their first time this year. So one big round of applause for them, please. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 c3lingo 2: And one more big thank about for the guys who brought the cough candies 99:59:59.999 --> 99:59:59.999 and cough drops in the booth. That's a lifesaver. Thanks. 99:59:59.999 --> 99:59:59.999 H: Thank you. Merci beaucoup. So we have some heart operation going on here. You 99:59:59.999 --> 99:59:59.999 have to switch it or not? Oh, you're good with computers. 99:59:59.999 --> 99:59:59.999 *laughing* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: He just *mimicks something*. So c3infrastructure from the subtitles. Your 99:59:59.999 --> 99:59:59.999 stage. Yeah. My microphone. Ha ha. td: So, thanks. Just a quick look into the 99:59:59.999 --> 99:59:59.999 subtitles. So what do we actually do when we subtitle a talk? Well, first of all, we 99:59:59.999 --> 99:59:59.999 take the video from the C3VOC and put it through speech recognition just to get a 99:59:59.999 --> 99:59:59.999 rough transcript that we can then give to angels to actually correct, because, well, 99:59:59.999 --> 99:59:59.999 machine speech recognition doesn't work so good at all. And then once we have a 99:59:59.999 --> 99:59:59.999 working transcript that humans have looked at, we put that through auto-timing, which 99:59:59.999 --> 99:59:59.999 just takes the transcript and aligns that with the audio, and that usually works 99:59:59.999 --> 99:59:59.999 pretty well. And, well, once that is finished, then we actually have working 99:59:59.999 --> 99:59:59.999 subtitles, but we give them to angels for another round of review just to fix any 99:59:59.999 --> 99:59:59.999 mistakes that got overlooked. And maybe sometimes the timing needs to be adjusted. 99:59:59.999 --> 99:59:59.999 And then, when that is done, well, the subtitle is released. And actually one of 99:59:59.999 --> 99:59:59.999 our angels did a nice chart about all this process that you can see here. It all 99:59:59.999 --> 99:59:59.999 sounds better, so thank you for that. Well, no presentation without graphs. As 99:59:59.999 --> 99:59:59.999 you can see, the important thing is really: everything goes up and to the 99:59:59.999 --> 99:59:59.999 right. On the bottom here we have finished seconds of transcribed talks. So this is 99:59:59.999 --> 99:59:59.999 really completed subtitles here. And it starts already quite high because it 99:59:59.999 --> 99:59:59.999 includes all the Congresses before. Then we have stuff that has been reviewed in 99:59:59.999 --> 99:59:59.999 orange. Stuff that has been timed but not reviewed yet in yellow. And transcribed 99:59:59.999 --> 99:59:59.999 but not yet timed stuff in green. All in all, we had 144 distinct angels. Yeah, I 99:59:59.999 --> 99:59:59.999 need to hurry up. 71% of which took 2 shifts and 10% took 7 or more shifts. So 99:59:59.999 --> 99:59:59.999 433 hours of work for 126 hours of material. And so far we've had 6 releases 99:59:59.999 --> 99:59:59.999 from this Congress and then lots of hours worked. All of these numbers are at least 99:59:59.999 --> 99:59:59.999 as high as last year's numbers, so good, thanks. When you have transcripts, you can 99:59:59.999 --> 99:59:59.999 do cool stuff with that. So, for example, generate word clouds to see what people 99:59:59.999 --> 99:59:59.999 like. And this case, people seem to like people and questions and time, which we 99:59:59.999 --> 99:59:59.999 don't have any here. So. Well, how do we actually keep track of all this 99:59:59.999 --> 99:59:59.999 complicated stuff? Well, we use a state- of-the-art NoSQL lock-free columnar data 99:59:59.999 --> 99:59:59.999 store, like many of the other teams also do. And well, thank you all of our angels 99:59:59.999 --> 99:59:59.999 for your hard work. And also thanks for the Heaven for supporting us. And then, 99:59:59.999 --> 99:59:59.999 well, if you if you feel bored between Congresses, you can still continue to work 99:59:59.999 --> 99:59:59.999 on transcripts. You have all the informations here, these slides will be 99:59:59.999 --> 99:59:59.999 online, follow us on Twitter. And thank you. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Please do your thing again, like your thing again, like do *mimicks 99:59:59.999 --> 99:59:59.999 something*. Take your laptop. [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 *laughing* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: So this was the last one. I think I will try my best to do something like this 99:59:59.999 --> 99:59:59.999 too. Actually I'm not good with computers, but I know someone who is and who takes 99:59:59.999 --> 99:59:59.999 very great care of everyone of us. So one of my highlights of every Congress, feel 99:59:59.999 --> 99:59:59.999 free, the LOC! LOC: Hello. I'm the stand-in for LOC. As 99:59:59.999 --> 99:59:59.999 with all good projects, they're too busy for documentation. They're packing. So LOC 99:59:59.999 --> 99:59:59.999 doesn't have anything. I'm more of the Department of Health and Safety again. So 99:59:59.999 --> 99:59:59.999 for everyone: we have the message from CERT that there were no work-related 99:59:59.999 --> 99:59:59.999 accidents that caused real harm. The odd broken Mate bottle maybe. But thank you 99:59:59.999 --> 99:59:59.999 for having built a city again safely and orderly, even with all the chaos. For the 99:59:59.999 --> 99:59:59.999 people who are driving, please make sure that the drugs wear off and that you get 99:59:59.999 --> 99:59:59.999 some sleep and for all people riding along, please keep the guys awake. That 99:59:59.999 --> 99:59:59.999 would be greatly appreciated. Go home safely. Thank you very much. 99:59:59.999 --> 99:59:59.999 *applause* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: So. Wow, ah, OK. So I'm very sorry to have to rush some teams and I'm very sorry 99:59:59.999 --> 99:59:59.999 that we don't have any time left. We are 1 minute over and I promised the teardown 99:59:59.999 --> 99:59:59.999 crew to not do overtime. So please, please give all the teams their respect and clap 99:59:59.999 --> 99:59:59.999 and tramp as loud as you can for now to finish! 99:59:59.999 --> 99:59:59.999 *standing ovation* [Filler, please remove me in amara] 99:59:59.999 --> 99:59:59.999 H: Everything! They did! For us! We did! For them! Why are you still sitting? You 99:59:59.999 --> 99:59:59.999 have to leave. Thank you. From the c3infrastructure Review. Goodbye. 99:59:59.999 --> 99:59:59.999 Subtitles created by many many volunteers and the c3subtitles.de team. Join us, and help us!
