1 99:59:59,999 --> 99:59:59,999 Herald: Hello and welcome to Infrastructure Review. This review is 2 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 3 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 4 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. 5 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 6 99:59:59,999 --> 99:59:59,999 Momo: All right, everyone, welcome to the State of the Internet manufacture report. 7 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 8 99:59:59,999 --> 99:59:59,999 for the network. So obviously, organizing Congress is a quite tedious task. Took us 9 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 10 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 11 99:59:59,999 --> 99:59:59,999 like 20 to 40 people. And we'll be busy wiping every device because that is 12 99:59:59,999 --> 99:59:59,999 actually what we do every year. We delete everything. There are no logs leaving this 13 99:59:59,999 --> 99:59:59,999 building and this will take us probably the next 24 hours. So yeah, for the usual 14 99:59:59,999 --> 99:59:59,999 numbers. Edge capacity: this year because you didn't use all the Internet last year, 15 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 16 99:59:59,999 --> 99:59:59,999 from HLKomm here in Leipzig, 100 gig from Deutsche Telekom and as well as 100 gig 17 99:59:59,999 --> 99:59:59,999 from BCIX which we got via DWDM wave to Berlin. In the core we used Juniper 18 99:59:59,999 --> 99:59:59,999 MX960s, MX480s, MX204s and QFX10002 in the yolocolo. Basically all the halls were 19 99:59:59,999 --> 99:59:59,999 connected via a 200 gig link and yolocolo had three times 100 gig. As probably the 20 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 21 99:59:59,999 --> 99:59:59,999 this year we also first off rejected RPKI invalid routes and secondly applied for 22 99:59:59,999 --> 99:59:59,999 the first time at congress BCP38 ingress filtering to be a good internet citizen 23 99:59:59,999 --> 99:59:59,999 and not to allow you to spoof IP addresses. So yeah, that was nice. As 24 99:59:59,999 --> 99:59:59,999 Congress keeps on growing, we have 2500 tables somewhere around the building in 25 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 26 99:59:59,999 --> 99:59:59,999 long cable and if you have switches to spare with 10 gig uplinks and POE+, feel 27 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 28 99:59:59,999 --> 99:59:59,999 are obviously again running Aruba Wi-Fi controllers. This year, like at camp we 29 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 30 99:59:59,999 --> 99:59:59,999 route the Wi-Fi traffic. And had quite a shitload of switches, most of them from 31 99:59:59,999 --> 99:59:59,999 Juniper, some Cisco 2960s, some Brocades which are new to us, and some crappy old 32 99:59:59,999 --> 99:59:59,999 HPE stuff which is basically configured for us to work like a brick you get from 33 99:59:59,999 --> 99:59:59,999 like eBay or whatnot. We had a few incidents this year we'd like to talk 34 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 35 99:59:59,999 --> 99:59:59,999 loss and missing router advertisements on the Wi-Fi. This was caused by some weird 36 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 37 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 38 99:59:59,999 --> 99:59:59,999 redundancy. There was a pixelflut client which somehow messed up his IP address and 39 99:59:59,999 --> 99:59:59,999 caused a broadcast storm which took down most parts of Hall 2. We found them, shut 40 99:59:59,999 --> 99:59:59,999 it down and deployed storm control to all our access switches. Yeah, to the Congress 41 99:59:59,999 --> 99:59:59,999 motto resource exhaustion: someone was running aggressive zmap scanning over the 42 99:59:59,999 --> 99:59:59,999 whole internet, came by our Wi-Fi access controller and caused a state table 43 99:59:59,999 --> 99:59:59,999 exhaustion. And that brought it down. We null-routed the source and yeah, there was 44 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 45 99:59:59,999 --> 99:59:59,999 another issue with Juniper vMX where it forgot it had a network card. We rebooted 46 99:59:59,999 --> 99:59:59,999 it and everything was fine again. So yeah, some numbers. You actually managed to use 47 99:59:59,999 --> 99:59:59,999 more bandwidth, thank you. [Filler, please remove me in amara] 48 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 49 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 50 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 51 99:59:59,999 --> 99:59:59,999 GHz, 96% in a peak. We had eleven 802.11ax clients. Our 52 99:59:59,999 --> 99:59:59,999 favorite one was obviously the one with the lovely hostname ILOVETHENOC. So yeah, 53 99:59:59,999 --> 99:59:59,999 about that number we have, 96% 5 GHz obviously shows us that we are finally at 54 99:59:59,999 --> 99:59:59,999 the point where we can say: thank you 2.4 GHz, it was nice. Goodbye. 55 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 56 99:59:59,999 --> 99:59:59,999 M: Also, obviously, thank you to our sponsors. We couldn't do this if we would 57 99:59:59,999 --> 99:59:59,999 not get like 10 millions, of list price obviously, of equipment and loan and quite 58 99:59:59,999 --> 99:59:59,999 a lot of services. So give them a round of applause as well. Thank you. 59 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 60 99:59:59,999 --> 99:59:59,999 M: And obviously NOC not only stands for Network Operation Center, but if you 61 99:59:59,999 --> 99:59:59,999 extend it, it is No CO2. So we believe in green power and clean traffic and 62 99:59:59,999 --> 99:59:59,999 therefore we obviously see that sustainability is a great part of our 63 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 64 99:59:59,999 --> 99:59:59,999 tchunk to serve your cheese boards, whatever you need. 65 99:59:59,999 --> 99:59:59,999 *laughter* [Filler, please remove me in amara] 66 99:59:59,999 --> 99:59:59,999 M: Also... [Filler, please remove me in amara] 67 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 68 99:59:59,999 --> 99:59:59,999 M: Also, we somehow estimated what our network will run us in CO2 and that was 69 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, 70 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 71 99:59:59,999 --> 99:59:59,999 better place, we actually offset all our CO2 and bought eleven tons of CO2 72 99:59:59,999 --> 99:59:59,999 emissions. And now Frederick is gonna tell you how we got all those numbers. 73 99:59:59,999 --> 99:59:59,999 Frederick: Yeah, as a good internet manufacture, we also do monitoring a lot 74 99:59:59,999 --> 99:59:59,999 and we run our own Prometheus server inside. You probably know the dashboard 75 99:59:59,999 --> 99:59:59,999 that we propagate all over the internet and that's powered by Prometheus. We have 76 99:59:59,999 --> 99:59:59,999 an internal Grafana that is part of this whole ecosystem. And if you are a little 77 99:59:59,999 --> 99:59:59,999 bit of a nerd, you might have clicked on the dashboard sections and seen that there 78 99:59:59,999 --> 99:59:59,999 are more dashboards than this. We fill our Prometheus with lots of different sources: 79 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 80 99:59:59,999 --> 99:59:59,999 the insights we need from all the network equipment. We have node_exporter, influx 81 99:59:59,999 --> 99:59:59,999 and all that, but we got a decent amount of data from everyone in the Congress 82 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 83 99:59:59,999 --> 99:59:59,999 showers. And we get the colo power, which also helps with estimating the CO2 84 99:59:59,999 --> 99:59:59,999 footprint. And everything is being configured by Netbox, which is a tool that 85 99:59:59,999 --> 99:59:59,999 is an asset database. And as I said, we have lots of dashboards and graphs. Of 86 99:59:59,999 --> 99:59:59,999 course, the public one where you can see lots of different things from everyone. 87 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. 88 99:59:59,999 --> 99:59:59,999 But this helps everyone to have a good understanding of what is happening 89 99:59:59,999 --> 99:59:59,999 currently. And we even draw a nice little Christmas trees on the Wi-Fi traffic for 90 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 91 99:59:59,999 --> 99:59:59,999 correctly. We have an internal dashboard which gives us a little bit of a status 92 99:59:59,999 --> 99:59:59,999 for build-up mostly: which switches and routers are up? And that gives us a very 93 99:59:59,999 --> 99:59:59,999 quick sight of all the devices that are out there. What's broken? What's not 94 99:59:59,999 --> 99:59:59,999 broken? We improved it a little and now have alarms so someone can look at stuff 95 99:59:59,999 --> 99:59:59,999 and see if things are broken, run out there and fix it. We also built 96 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 97 99:59:59,999 --> 99:59:59,999 it better because the graphing library doesn't allow us to do it better. If 98 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 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 100 99:59:59,999 --> 99:59:59,999 the links between it and how much capacity is being used. Red indicates that it's 101 99:59:59,999 --> 99:59:59,999 used more heavily. We also have that for the yolocolo. And all the traffic around 102 99:59:59,999 --> 99:59:59,999 it as well. And, yeah, teardown starts now. Please don't touch our equipment. And 103 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 104 99:59:59,999 --> 99:59:59,999 helping hands. But please in an organized way don't disassemble switches or access 105 99:59:59,999 --> 99:59:59,999 points. We have lists and everything. We need to account for everything. So please 106 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 107 99:59:59,999 --> 99:59:59,999 CO2. Thank you. [Filler, please remove me in amara] 108 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 109 99:59:59,999 --> 99:59:59,999 H: So thanks a lot. Actually, because you're clearly the backbone or one of 110 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 111 99:59:59,999 --> 99:59:59,999 or two questions. Is anyone having a question right now? 112 99:59:59,999 --> 99:59:59,999 Someone is standing up. Right, microphone number one, please. 113 99:59:59,999 --> 99:59:59,999 Q: Hey, we've absolutely don't ... [Filler, please remove me in amara] 114 99:59:59,999 --> 99:59:59,999 H: Nearer, nearer. [Filler, please remove me in amara] 115 99:59:59,999 --> 99:59:59,999 Q: We've absolutely done bcp38 in previous years, by the way. 116 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. 117 99:59:59,999 --> 99:59:59,999 We've been good netizens in previous years as well. 118 99:59:59,999 --> 99:59:59,999 H: Oh, you're right. Thank you. Was there another question or something else to 119 99:59:59,999 --> 99:59:59,999 correct them? Because they clearly don't know what they're doing. 120 99:59:59,999 --> 99:59:59,999 *laughter* [Filler, please remove me in amara] 121 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 122 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 123 99:59:59,999 --> 99:59:59,999 here next year? M: They'll definitely have a home. But as 124 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 125 99:59:59,999 --> 99:59:59,999 overused and not even remotely suited for that amount of clients we put on it. 126 99:59:59,999 --> 99:59:59,999 Q: A follow-up for the ESP32. How exactly can you locate them through the wireless 127 99:59:59,999 --> 99:59:59,999 if they are lost? M: Well, we can't. We can basically look 128 99:59:59,999 --> 99:59:59,999 at which access point they are, and then if someone really would want to, we could 129 99:59:59,999 --> 99:59:59,999 start triangulation, but we've never done that before. So yeah, we can just pin them 130 99:59:59,999 --> 99:59:59,999 roughly to an access point. H: Maybe we can ask c3nav next time. So 131 99:59:59,999 --> 99:59:59,999 please give the NOC a hand. Thank you. 132 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 133 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, 134 99:59:59,999 --> 99:59:59,999 I'm going to try. Ah! Thank you. Your stage. 135 99:59:59,999 --> 99:59:59,999 Garvin: Thanks. [Filler, please remove me in amara] 136 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 137 99:59:59,999 --> 99:59:59,999 Maria: Hi, my name is Maria. [Filler, please remove me in amara] 138 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 139 99:59:59,999 --> 99:59:59,999 about the phone infrastructure at this event. 140 99:59:59,999 --> 99:59:59,999 M: Yeah. So we arrived at day -6 and planned on hacking some things 141 99:59:59,999 --> 99:59:59,999 and socializing and we planned a team event, but then everything was different. 142 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 143 99:59:59,999 --> 99:59:59,999 is up, internet is up, everything is just working nicely. You can start hook up your 144 99:59:59,999 --> 99:59:59,999 telephony system right now." And I was like, whoa. So thanks a lot NOC. Really 145 99:59:59,999 --> 99:59:59,999 great performance this year, we were amazed. Nobody expected that it works so 146 99:59:59,999 --> 99:59:59,999 well. [Filler, please remove me in amara] 147 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 148 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 149 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 150 99:59:59,999 --> 99:59:59,999 DECTs and we deployed 51 SIP telephones. We also deployed 67 antennas and we had a 151 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 152 99:59:59,999 --> 99:59:59,999 done. I guess the remaining things are not that important. So this is the overview of 153 99:59:59,999 --> 99:59:59,999 DECT coverage at the event. Only level zero, because otherwise I think it would 154 99:59:59,999 --> 99:59:59,999 be overcrowded to show. Just so that you can get a rough impression on how many 155 99:59:59,999 --> 99:59:59,999 antennas we deployed in order to give you this DECT coverage. That you can be 156 99:59:59,999 --> 99:59:59,999 reached almost everywhere in the event and that you can see how our tooling looks 157 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 158 99:59:59,999 --> 99:59:59,999 seamless handover work so that you can start at our desk, walk through the area, 159 99:59:59,999 --> 99:59:59,999 into the lounge and just continue talking. And oh, there are also some antennas that 160 99:59:59,999 --> 99:59:59,999 are outside of the building. What could that be? 161 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 162 99:59:59,999 --> 99:59:59,999 photo. And people got really confused about it because we also had DECT coverage 163 99:59:59,999 --> 99:59:59,999 at main station. G: Yeah. So I got a call roughly at 4:00 164 99:59:59,999 --> 99:59:59,999 p.m. in the morning. [Filler, please remove me in amara] 165 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 166 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 167 99:59:59,999 --> 99:59:59,999 night. Why did you do this? M: Yeah. So we also had problems. We have 168 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 169 99:59:59,999 --> 99:59:59,999 your number before you even arrive, and then everything is set up and you don't 170 99:59:59,999 --> 99:59:59,999 have to call your token anymore. And people get really confused because they 171 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 172 99:59:59,999 --> 99:59:59,999 this unexpected simplicity to them. G: And then we had a battery issue this 173 99:59:59,999 --> 99:59:59,999 year. We had not enough batteries and, you know, batteries are always empty in the 174 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 175 99:59:59,999 --> 99:59:59,999 that? M: So we build a new device. That's our 176 99:59:59,999 --> 99:59:59,999 microwave and it can also charge devices. So, many thanks to C3Power, because they 177 99:59:59,999 --> 99:59:59,999 helped us with tooling and actually they have expertise to put power cables on 178 99:59:59,999 --> 99:59:59,999 devices like this. Thank you very much. [Filler, please remove me in amara] 179 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 180 99:59:59,999 --> 99:59:59,999 G: In the last years we were often asked "how expensive is your service actually?". 181 99:59:59,999 --> 99:59:59,999 So we decided that we now provide invoices so you can see how expensive our services 182 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 183 99:59:59,999 --> 99:59:59,999 on the invoices, most is sponsored by CCC. M: Yeah. And people also paid with Mate 184 99:59:59,999 --> 99:59:59,999 which is really awesome. G: Yeah. And also people have invoices on 185 99:59:59,999 --> 99:59:59,999 a fraction of a cent and they got quite creative on how they can pay us. 186 99:59:59,999 --> 99:59:59,999 *laughter* [Filler, please remove me in amara] 187 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 188 99:59:59,999 --> 99:59:59,999 M: So here are some more stats. We have 7473 registered extensions. 189 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 190 99:59:59,999 --> 99:59:59,999 things and we were looking at villages in Saarland and then we thought, this is a 191 99:59:59,999 --> 99:59:59,999 stupid comparison, but we didn't remove this. 192 99:59:59,999 --> 99:59:59,999 M: So there were 5021 attached DECT phones and 3251 concurrent DECT phones. Which is 193 99:59:59,999 --> 99:59:59,999 about more than 1000 more than last year. G: So thanks a lot for using DECT. 194 99:59:59,999 --> 99:59:59,999 M: Yeah. We had... [Filler, please remove me in amara] 195 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 196 99:59:59,999 --> 99:59:59,999 M: There were also max 120 calls in parallel, and we had more than 300 197 99:59:59,999 --> 99:59:59,999 thousand calls in total. That's also really, really much. We had five eating 198 99:59:59,999 --> 99:59:59,999 meetings at heaven, the angel eating place, and there were an average of 42 199 99:59:59,999 --> 99:59:59,999 eating meeting live viewers. We had two lectures. You can see them on media.ccc.de 200 99:59:59,999 --> 99:59:59,999 and we had 23 super fast charged phones in our microwave. 201 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 202 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 203 99:59:59,999 --> 99:59:59,999 there were some DDOS attack on our account system and somebody configured over 4000 204 99:59:59,999 --> 99:59:59,999 extensions with really stupid names. And it took us quite a while to get rid of 205 99:59:59,999 --> 99:59:59,999 them again cleanly from the system because the synchronization turned out to be 206 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 207 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 208 99:59:59,999 --> 99:59:59,999 your own infrastructure. [Filler, please remove me in amara] 209 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 210 99:59:59,999 --> 99:59:59,999 G: So as a consequence of this, we only allow now only 50 extensions per account 211 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 212 99:59:59,999 --> 99:59:59,999 valid use case. [Filler, please remove me in amara] 213 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 214 99:59:59,999 --> 99:59:59,999 responsible institution to give us the manufacturer. But it's really secret. So 215 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 216 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 217 99:59:59,999 --> 99:59:59,999 build more awesome features for you. [Filler, please remove me in amara] 218 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 219 99:59:59,999 --> 99:59:59,999 seems to be super secret. Whatever. [Filler, please remove me in amara] 220 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 221 99:59:59,999 --> 99:59:59,999 you click on it, then you can enter the model. 222 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 223 99:59:59,999 --> 99:59:59,999 for you to ask questions. [Filler, please remove me in amara] 224 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 225 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 226 99:59:59,999 --> 99:59:59,999 have to...? Ah, someone is getting up. So microphone number 1, please. 227 99:59:59,999 --> 99:59:59,999 Q: Yes, a few years ago there was a translation service via DECT. Is the 228 99:59:59,999 --> 99:59:59,999 capacity enough to service also this crowd? 229 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 230 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 231 99:59:59,999 --> 99:59:59,999 channel and the problem is that the new system doesn't support this. Let me say 232 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 233 99:59:59,999 --> 99:59:59,999 see that there is some potential. H: I see someone at microphone number 3, 234 99:59:59,999 --> 99:59:59,999 please. This would be the last question because we have to hurry a bit. 235 99:59:59,999 --> 99:59:59,999 Q: Can I know a little bit more about the super charging microwave? I'm confused. 236 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 237 99:59:59,999 --> 99:59:59,999 M: Sure, you can come to our POC desk and then we answer all your questions. 238 99:59:59,999 --> 99:59:59,999 H: Ooh... mystery. Please, give the POC a hand. 239 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 240 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 241 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 242 99:59:59,999 --> 99:59:59,999 smile then looks better. Try this. Yeah. Right. Try this. 243 99:59:59,999 --> 99:59:59,999 - 423. - Maybe you have to use GSM. 244 99:59:59,999 --> 99:59:59,999 - 23 test. - What happened? 245 99:59:59,999 --> 99:59:59,999 - Hello. Hello. - Aah. 246 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 247 99:59:59,999 --> 99:59:59,999 using osmocom open source software for 2G and 3G, and open5gs interfacing with the 248 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 249 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 250 99:59:59,999 --> 99:59:59,999 SIM cards every year. We need to manufacture new ones. You can even call 251 99:59:59,999 --> 99:59:59,999 outside like you can with DECT phones. Lynxis: Hello. I'm Lynxis. So as every 252 99:59:59,999 --> 99:59:59,999 year for the GSM team, the first problem is the license. That's the first step 253 99:59:59,999 --> 99:59:59,999 usually. Because in Germany, you have to get the official form, get a license but 254 99:59:59,999 --> 99:59:59,999 ... Where do you get it? What can you ask for frequencies? Because, for example, the 255 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. 256 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 257 99:59:59,999 --> 99:59:59,999 usually get the license middle of december, maybe start of december. So it's 258 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 259 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 260 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 10 261 99:59:59,999 --> 99:59:59,999 Mhz from Telefonica. So thanks Telefonica for borrowing us spectrum. 262 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 263 99:59:59,999 --> 99:59:59,999 L: Just a short example of how the spectrum looks like. The yellow stuff is 264 99:59:59,999 --> 99:59:59,999 usually somewhere behind actually. By the way, this microphone, it might share the 265 99:59:59,999 --> 99:59:59,999 same frequency with us. But so far, we haven't found any interference together 266 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 267 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 268 99:59:59,999 --> 99:59:59,999 them both in the same frequencies? It's not good. But you see the spikes, this 269 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 270 99:59:59,999 --> 99:59:59,999 works because they are using different codings. But I have heard from people who 271 99:59:59,999 --> 99:59:59,999 know more about it, this is not the way you use it. 272 99:59:59,999 --> 99:59:59,999 *laughing* [Filler, please remove me in amara] 273 99:59:59,999 --> 99:59:59,999 L: So we took some photos of our base stations. This is actually the fairy dust 274 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 275 99:59:59,999 --> 99:59:59,999 more fairy dust in our 3G femtocells and our 4G cells. They are looking like small 276 99:59:59,999 --> 99:59:59,999 toasters. They are taking actually 90 watts via POE, they have special POE 277 99:59:59,999 --> 99:59:59,999 adapters. So maybe we could ask if somebody can do a similar adapter to get 278 99:59:59,999 --> 99:59:59,999 even running a toaster on the line. So basically for the 4G setup this year, 279 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 280 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 281 99:59:59,999 --> 99:59:59,999 we don't have yet voice so you have to select specifically to join the LTE 282 99:59:59,999 --> 99:59:59,999 network. That worked quite fine if you change it. So your phone will register. 283 99:59:59,999 --> 99:59:59,999 Everything fine there. GSM1: So the rollout this year: we had the 284 99:59:59,999 --> 99:59:59,999 voice working on day 0 which is new. [Filler, please remove me in amara] 285 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 286 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 287 99:59:59,999 --> 99:59:59,999 camp this year. Yeah, but unfortunately we lost crypto password, so LTE roll out took 288 99:59:59,999 --> 99:59:59,999 a bit longer this time. Sorry. So some numbers. In total we saw just about 1100 289 99:59:59,999 --> 99:59:59,999 people doing a location updating on our network and 845 eventphone tokens were 290 99:59:59,999 --> 99:59:59,999 dialed on the GSM. That is 2G or 3G. And there were roughly 200 phones actively 291 99:59:59,999 --> 99:59:59,999 subscribed on the network at all times. And even though we basically only deployed 292 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 293 99:59:59,999 --> 99:59:59,999 were roughly more than half of all the phones were still subscribed on 2G instead 294 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. 295 99:59:59,999 --> 99:59:59,999 So that's a bit surprising. And SIM cards: starting from the bottom, we sold about 296 99:59:59,999 --> 99:59:59,999 700 SIM cards, but only saw half of them activated, which is curious. And luckily, 297 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 298 99:59:59,999 --> 99:59:59,999 to get cards manufactured. So we are very glad for everyone who brings old SIM cards 299 99:59:59,999 --> 99:59:59,999 from previous events. We might even consider introducing charging phone calls 300 99:59:59,999 --> 99:59:59,999 only for SIM cards that are newly bought. So if you want to continue calling for 301 99:59:59,999 --> 99:59:59,999 free, rather bring your old SIM cards. [Filler, please remove me in amara] 302 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 303 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 304 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. 305 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 306 99:59:59,999 --> 99:59:59,999 SIM cards, we give out all the keys you want to have to play with it. 307 99:59:59,999 --> 99:59:59,999 GSM1: So operation was mostly smooth, except iPhones, for unknown reasons. And 308 99:59:59,999 --> 99:59:59,999 except the data service, which might even be related because maybe Apple is a bit 309 99:59:59,999 --> 99:59:59,999 more strict on whether data service is working reliably. Yeah, we still had some 310 99:59:59,999 --> 99:59:59,999 problems in the SGs instance introducing 3G changing between the radio access 311 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 312 99:59:59,999 --> 99:59:59,999 you see, we had many more tickets than the POC. This is actually reversed from the 313 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 314 99:59:59,999 --> 99:59:59,999 some backlog and canceled and fantasy tasks. It worked pretty nicely. Are you 315 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 316 99:59:59,999 --> 99:59:59,999 denial of service attack. The code was the same as previous years and we never saw 317 99:59:59,999 --> 99:59:59,999 this before. But this year we got an invalid mobile identity which managed to 318 99:59:59,999 --> 99:59:59,999 crash our mobile switching center. And thank you very much for uncovering this 319 99:59:59,999 --> 99:59:59,999 bug and thanks to fixeria for fixing it on day 2. Ever since the mobile switching 320 99:59:59,999 --> 99:59:59,999 center for Voice and SMS and subscription has been running stable. 321 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 322 99:59:59,999 --> 99:59:59,999 L: Maybe some interference. We recovered the old phones again. Last year we 323 99:59:59,999 --> 99:59:59,999 couldn't support them. But we managed to implement the missing parts. Old phones 324 99:59:59,999 --> 99:59:59,999 could work if they support the frequencies. So that's really nice. Maybe 325 99:59:59,999 --> 99:59:59,999 next time. Since camp, we also did a nice angel helpdesk. And it was really 326 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 327 99:59:59,999 --> 99:59:59,999 motivated angels. Thanks to everybody who helped us, it was really great. 328 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 329 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 330 99:59:59,999 --> 99:59:59,999 for everything they did. [Filler, please remove me in amara] 331 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 332 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, 333 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 334 99:59:59,999 --> 99:59:59,999 have working microphones. Chaos post 1: Sorry, we need to interrupt 335 99:59:59,999 --> 99:59:59,999 you anyway. H: OK. So tell them, chaos post! Chaos 336 99:59:59,999 --> 99:59:59,999 post! [Filler, please remove me in amara] 337 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 338 99:59:59,999 --> 99:59:59,999 Chaos post 1: Sorry, guys, we interrupt... [Filler, please remove me in amara] 339 99:59:59,999 --> 99:59:59,999 H: Let's get rid of the broken one because it's not working anyway. 340 99:59:59,999 --> 99:59:59,999 Chaos post 1: All right. Sorry, we are interrupting for a few minutes only. We 341 99:59:59,999 --> 99:59:59,999 would like to deliver a few statistics as well. So thanks of all, we had multiple 342 99:59:59,999 --> 99:59:59,999 chaos deliverers working throughout the whole Congress 24/7 basically, delivering 343 99:59:59,999 --> 99:59:59,999 at the speed of chaos, as our mission statement clearly states. So thank you 344 99:59:59,999 --> 99:59:59,999 therefore, first of all thank you very much to all of you who contributed to 345 99:59:59,999 --> 99:59:59,999 that. [Filler, please remove me in amara] 346 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 347 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 348 99:59:59,999 --> 99:59:59,999 delivered about 3000 external postcards. So that means with like outside chaos, so 349 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 42 350 99:59:59,999 --> 99:59:59,999 countries all over the world. So you guys are really good connected internationally. 351 99:59:59,999 --> 99:59:59,999 And also, we don't have exact numbers, but we estimate around 3500, no, 35000, 352 99:59:59,999 --> 99:59:59,999 internal postcards. And you also use our online office for a total of 789 times. So 353 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 354 99:59:59,999 --> 99:59:59,999 write a lot of postcards! [Filler, please remove me in amara] 355 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 356 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 357 99:59:59,999 --> 99:59:59,999 services. As already on camp, we had the serving proposal, basically a pre- 358 99:59:59,999 --> 99:59:59,999 assembled text, you just had to cross what you want. The postbox certification and of 359 99:59:59,999 --> 99:59:59,999 course, the bi-directional chaos, in Germany also known as "Einschreiben mit 360 99:59:59,999 --> 99:59:59,999 Rückschein". H: Wow. 361 99:59:59,999 --> 99:59:59,999 Chaos post 2: And this time we also offered some new services. We had like 362 99:59:59,999 --> 99:59:59,999 sang telegrams, gesunges Telegram in Deutsch. We had a forever alone box for 363 99:59:59,999 --> 99:59:59,999 people wanting to write postcards with or exchange postcards with no idea who to 364 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 365 99:59:59,999 --> 99:59:59,999 a really nice selection of perfumes for scented postcards. You could write some 366 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 367 99:59:59,999 --> 99:59:59,999 security, or rather temper evidence, because we had some scratch off stickers 368 99:59:59,999 --> 99:59:59,999 for you. And also we had over 30 new postcard designs that you could use for 369 99:59:59,999 --> 99:59:59,999 postcards. [Filler, please remove me in amara] 370 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 371 99:59:59,999 --> 99:59:59,999 Chaos post 1: Short remark for the love letters and the perfumes. Well, that was 372 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 373 99:59:59,999 --> 99:59:59,999 stamping all of that, smelling all the perfume all the time. 374 99:59:59,999 --> 99:59:59,999 Chaos post 2: And then brushing your hands really thoroughly because, well, that 375 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 376 99:59:59,999 --> 99:59:59,999 little remark. It's not a good idea to use it for addressing and the message. 377 99:59:59,999 --> 99:59:59,999 *laughing* [Filler, please remove me in amara] 378 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 379 99:59:59,999 --> 99:59:59,999 supported mail this year and we had 130 letters for activists in 380 99:59:59,999 --> 99:59:59,999 prison, which I find really great. I think that's something we can all support. 381 99:59:59,999 --> 99:59:59,999 Amazing. [Filler, please remove me in amara] 382 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 383 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 384 99:59:59,999 --> 99:59:59,999 Congress. [Filler, please remove me in amara] 385 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 386 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. 387 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. 388 99:59:59,999 --> 99:59:59,999 VOC1: Hurry up. Welcome, guys. So. Yeah. We don't have as many statistics as usual. 389 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 390 99:59:59,999 --> 99:59:59,999 covered 10 stages apart from the 5 stages that we do usually for Congress. We had 391 99:59:59,999 --> 99:59:59,999 streams from the critical decentralisation cluster, Sendezentrum, Wikipaka WG, Open 392 99:59:59,999 --> 99:59:59,999 Infrastructure Orbit, Chaos West. And in total, we served 255 hours and 35 minutes 393 99:59:59,999 --> 99:59:59,999 of total talk time. So you know what to do until the next Congress. 394 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 395 99:59:59,999 --> 99:59:59,999 VOC1: And of course, sustainability was a big topic during this Congress. So part of 396 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 397 99:59:59,999 --> 99:59:59,999 it at lower resolution. And so far we've been using 4 Xeon-based machines and 2 398 99:59:59,999 --> 99:59:59,999 desktop machines. And thanks to hardware- based encoding, we now replace this with a 399 99:59:59,999 --> 99:59:59,999 single laptop. As you can maybe read, this is critical infrastructure now. And for 400 99:59:59,999 --> 99:59:59,999 all the streams, for 30 reencoding streams, we are on a 45 watt power budget 401 99:59:59,999 --> 99:59:59,999 now. And as an added benefit, because we also encode the master slides with 402 99:59:59,999 --> 99:59:59,999 hardware encoders, and hardware encoders can generally use a higher profile that 403 99:59:59,999 --> 99:59:59,999 allows for better quality in real time, you now get a better picture as well. So, 404 99:59:59,999 --> 99:59:59,999 yeah. [Filler, please remove me in amara] 405 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 406 99:59:59,999 --> 99:59:59,999 VOC1: And of course, we had some minor fuckups this year. We thought the audio 407 99:59:59,999 --> 99:59:59,999 setup was a bit less complex. But when we checked rooms, we had buzzing everywhere. 408 99:59:59,999 --> 99:59:59,999 So we replaced some SDI lines with fiber and turns out buzzing goes away. Then the 409 99:59:59,999 --> 99:59:59,999 PA sound console had a buggy DANTE card. After you reboot them, the auxiliary out 410 99:59:59,999 --> 99:59:59,999 to the VOC cameras was muted. So that messed up the particular talk that has 411 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 412 99:59:59,999 --> 99:59:59,999 our audio mixers actually had broken outputs. I don't know how we did that, but 413 99:59:59,999 --> 99:59:59,999 it clearly shows that they've been used on one event or another during the last 414 99:59:59,999 --> 99:59:59,999 years, which is actually a good thing we may think. On the Wikipaka stage, we did 415 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 416 99:59:59,999 --> 99:59:59,999 things properly, well, then you run into edge cases with things. And yeah. So I 417 99:59:59,999 --> 99:59:59,999 need to hurry up. And one virtualization host suddenly started leaking memory. And 418 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 419 99:59:59,999 --> 99:59:59,999 very sorry about that. Updating the kernel helped and we have no idea what happened. 420 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 421 99:59:59,999 --> 99:59:59,999 later, that may not be possible because we ran temporarily out of space. But if you 422 99:59:59,999 --> 99:59:59,999 watch this on media.ccc.de, and the talks were not yet released, we have relive 423 99:59:59,999 --> 99:59:59,999 integration, so the talks show up in media.ccc.de even though there is no 424 99:59:59,999 --> 99:59:59,999 proper release yet, for your convenience. And main track and assemblies are now 425 99:59:59,999 --> 99:59:59,999 integrated in all events, so you don't have to click through 4 separate events to 426 99:59:59,999 --> 99:59:59,999 find your favorite talk. And now I pass to Pat to talk about VOCTOMIX 2. 427 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 428 99:59:59,999 --> 99:59:59,999 VOCTOMIX, it's now called VOC2MIX. And Peter was doing that meme some weeks ago, 429 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 430 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 431 99:59:59,999 --> 99:59:59,999 was not working anymore. That was a little bit hot, but it worked. And, the redesign 432 99:59:59,999 --> 99:59:59,999 caused the new UI, complete with some new base features. We have now transitions 433 99:59:59,999 --> 99:59:59,999 where pictures are moving, and we have insertions for blending text into the 434 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, 435 99:59:59,999 --> 99:59:59,999 I think. [Filler, please remove me in amara] 436 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 437 99:59:59,999 --> 99:59:59,999 Pat: And some mixer angels were exploring the software and they found some bonus 438 99:59:59,999 --> 99:59:59,999 features like random video distortion in some cases, which I have to fix, I think. 439 99:59:59,999 --> 99:59:59,999 And the party mode where you click some buttons and they are clicking without any 440 99:59:59,999 --> 99:59:59,999 doing of the user and everything is flickering and they called it party mode. 441 99:59:59,999 --> 99:59:59,999 This is what the current pipeline looks like. We have now over 200 gstreamer 442 99:59:59,999 --> 99:59:59,999 elements doing all this stuff to get your pictures, which you are having on the 443 99:59:59,999 --> 99:59:59,999 stream and in the recordings. That's it. VOC1: So, of course, there were some 444 99:59:59,999 --> 99:59:59,999 issues. I mean VOCTOMIX2 is essentially a rewrite. 445 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 446 99:59:59,999 --> 99:59:59,999 might call it a quit. VOC1: OK OK OK. So... 447 99:59:59,999 --> 99:59:59,999 H: Pressure! VOC1: Yes, I know. But you're not making 448 99:59:59,999 --> 99:59:59,999 things better. So one thing to mention: we had to deploy a sweaty finger fix after 449 99:59:59,999 --> 99:59:59,999 the first talk started. Ok, here are your stats, read them now, read them read them 450 99:59:59,999 --> 99:59:59,999 read them! [Filler, please remove me in amara] 451 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 452 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 453 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 454 99:59:59,999 --> 99:59:59,999 very eloquent and good-looking. Then we have 70 stage managers and stage 455 99:59:59,999 --> 99:59:59,999 supporters. We had 150 shows on official stages and the assemblies on top of it. We 456 99:59:59,999 --> 99:59:59,999 have one stage fright council yet for the speakers who took care of at least six 457 99:59:59,999 --> 99:59:59,999 talks. And then we threw away over 100 hosting cards on day 1 only. So clearly, 458 99:59:59,999 --> 99:59:59,999 give a hand for the SHOC. [Filler, please remove me in amara] 459 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 460 99:59:59,999 --> 99:59:59,999 H: So next, c3power. Your time. Arif: So my name is Arif Guy. I am from 461 99:59:59,999 --> 99:59:59,999 the power team and from the radio operation center. We make the power. We 462 99:59:59,999 --> 99:59:59,999 load five double trucks of shit out on Sunday 15th. We deploy a lot of power 463 99:59:59,999 --> 99:59:59,999 boxes and many cables. So we have teardown today so every help is needed. We have 464 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 465 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 466 99:59:59,999 --> 99:59:59,999 is very bad. And the other one was the Waffle Operation Center so you see they 467 99:59:59,999 --> 99:59:59,999 have a nice power factor. So please use more ohmic devices like heaters, waffle 468 99:59:59,999 --> 99:59:59,999 iron or something. We only have 5 Seaview to monitor Yolocolo. You have on 469 99:59:59,999 --> 99:59:59,999 c3power.top a Grafana link that also links to the main Grafana to the NOC. Another 470 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 471 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. 472 99:59:59,999 --> 99:59:59,999 *recorded music from the lounge* [Filler, please remove me in amara] 473 99:59:59,999 --> 99:59:59,999 Arif: It's very nice. [Filler, please remove me in amara] 474 99:59:59,999 --> 99:59:59,999 *recorded music from the lounge* [Filler, please remove me in amara] 475 99:59:59,999 --> 99:59:59,999 Arif: As you see, the only thing is... [Filler, please remove me in amara] 476 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 477 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 478 99:59:59,999 --> 99:59:59,999 next slide please. So for the radio team we have 120 portable radios. We have 479 99:59:59,999 --> 99:59:59,999 updated them to a new firmware, and a new programming software with a new feature 480 99:59:59,999 --> 99:59:59,999 that is a lot slower than the last version. Very nice. 50 bring-your-own- 481 99:59:59,999 --> 99:59:59,999 device radios. 5 dead radios from the camp. 2 dead from 36c3. 2 dead repeaters 482 99:59:59,999 --> 99:59:59,999 from the camp. 1 dead on arrival on this stage. 3 rental repeaters from 2 483 99:59:59,999 --> 99:59:59,999 companies, one we picked up in Hannover just before the Congress, and even the 484 99:59:59,999 --> 99:59:59,999 windows PC crashed down dead on arrival. Business as usual. So, next team! 485 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 486 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. 487 99:59:59,999 --> 99:59:59,999 It's well, sustainability. Your stage, go for it. Here, feel free. 488 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 489 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 490 99:59:59,999 --> 99:59:59,999 projects was the drinking water dispensers. So for angels, we had drinking 491 99:59:59,999 --> 99:59:59,999 water from a dispenser rather than from bottles and they could refill their 492 99:59:59,999 --> 99:59:59,999 bottles. We go through some stats there. So when we started planning how difficult 493 99:59:59,999 --> 99:59:59,999 it was to implement it, the locations, and how many volunteers, satisfaction was very 494 99:59:59,999 --> 99:59:59,999 high for this one. So thank you to c3geld who really helped organize the water 495 99:59:59,999 --> 99:59:59,999 dispensers with us. We're very happy. They were really great. Please give them a 496 99:59:59,999 --> 99:59:59,999 round of applause. [Filler, please remove me in amara] 497 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 498 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 499 99:59:59,999 --> 99:59:59,999 encourage people not to throw away their electronics. Of course, they can be 500 99:59:59,999 --> 99:59:59,999 recycled. So we have deployed 10 boxes. You can find them in the sticker stations. 501 99:59:59,999 --> 99:59:59,999 And we did this in collaboration with the hardware hacking area. Thank you. And 502 99:59:59,999 --> 99:59:59,999 other assemblies. Oh, wow, you are really fast. 503 99:59:59,999 --> 99:59:59,999 H: Yes I am. Amy: Okay! 504 99:59:59,999 --> 99:59:59,999 H: Others are waiting! Amy: Okay. So the last one I wanted to go 505 99:59:59,999 --> 99:59:59,999 through. We have two initiatives on this one. I'm sorry for the trashy picture 506 99:59:59,999 --> 99:59:59,999 there. We have organic bins in the halls. It was very, very difficult to do this. 507 99:59:59,999 --> 99:59:59,999 But actually it was quite satisfactory. But I would say there is room for 508 99:59:59,999 --> 99:59:59,999 improvement there. And there was also an initiative for recycling cigaret butts. So 509 99:59:59,999 --> 99:59:59,999 we actually had two people go round, collect your cigaret butts and they will 510 99:59:59,999 --> 99:59:59,999 be recycled into cool ashtrays. What a success! Thank you so much to everyone who 511 99:59:59,999 --> 99:59:59,999 collaborated with us. We couldn't do out without your help. 512 99:59:59,999 --> 99:59:59,999 H: Thank you. Your applause, please. [Filler, please remove me in amara] 513 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 514 99:59:59,999 --> 99:59:59,999 H: So unfortunately, the c3sign is not coming. So just take a look at those 515 99:59:59,999 --> 99:59:59,999 pictures while I go through them. And now the next one is C3 Assemblies. Here, take 516 99:59:59,999 --> 99:59:59,999 this one. Thank you. Be quick. Pingu: Hi, my name is Pingu. I'm here for 517 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 518 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 519 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. 520 99:59:59,999 --> 99:59:59,999 Because for some figures we had 419 assemblies to place on this area which is 521 99:59:59,999 --> 99:59:59,999 about 35000 square meters. We had 3000 tables all over, 2500 in the assemblies, 522 99:59:59,999 --> 99:59:59,999 with 6000 chairs. And here, please give a big applause to the C3Möbelhaus or IKEA as 523 99:59:59,999 --> 99:59:59,999 you call it. [Filler, please remove me in amara] 524 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 525 99:59:59,999 --> 99:59:59,999 Pingu: Because the Möbelhaus basically placed all the tables in a magic night on 526 99:59:59,999 --> 99:59:59,999 basically day -2. And they will disappear with the help of C3Möbelhaus today. We 527 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- 528 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... 529 99:59:59,999 --> 99:59:59,999 Oh. H: Thank you. 530 99:59:59,999 --> 99:59:59,999 Pingu: Thank you. And just one thing, for teardown, for tearing down the assemblies, 531 99:59:59,999 --> 99:59:59,999 please stack the chairs on the assembly but leave every chair and every table on 532 99:59:59,999 --> 99:59:59,999 the assembly, we will get rid of them. H: Thanks a lot. Your applause. So the 533 99:59:59,999 --> 99:59:59,999 next ones are... Les prochains, ce sont les gens de c3lingo, voilà, vos tours! 534 99:59:59,999 --> 99:59:59,999 c3lingo 1: Hallo! Schön euch mal (...) Wir sind übersetzet. (...) 535 99:59:59,999 --> 99:59:59,999 German> Oh, sorry. Well, I'm also fine with that. 536 99:59:59,999 --> 99:59:59,999 We translated all the German talks into English. All the English talks into 537 99:59:59,999 --> 99:59:59,999 German. All in all, fifteen thousand minutes in seven different target 538 99:59:59,999 --> 99:59:59,999 languages. And here is from the second language team, who talk all the non- 539 99:59:59,999 --> 99:59:59,999 English and non-German things. c3lingo 2: Okay. So basically we did have 540 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 541 99:59:59,999 --> 99:59:59,999 we even have currently, exactly, right now, another one which is translated into 542 99:59:59,999 --> 99:59:59,999 Swabian. So if you want to listen into it. [Filler, please remove me in amara] 543 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 544 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 545 99:59:59,999 --> 99:59:59,999 of 3 that it was translated not only once, but twice. Into either French, Spanish, 546 99:59:59,999 --> 99:59:59,999 Russian, or Polish. One special mention for the Russian and Polish teams, that was 547 99:59:59,999 --> 99:59:59,999 their first time this year. So one big round of applause for them, please. 548 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 549 99:59:59,999 --> 99:59:59,999 c3lingo 2: And one more big thank about for the guys who brought the cough candies 550 99:59:59,999 --> 99:59:59,999 and cough drops in the booth. That's a lifesaver. Thanks. 551 99:59:59,999 --> 99:59:59,999 H: Thank you. Merci beaucoup. So we have some heart operation going on here. You 552 99:59:59,999 --> 99:59:59,999 have to switch it or not? Oh, you're good with computers. 553 99:59:59,999 --> 99:59:59,999 *laughing* [Filler, please remove me in amara] 554 99:59:59,999 --> 99:59:59,999 H: He just *mimicks something*. So c3infrastructure from the subtitles. Your 555 99:59:59,999 --> 99:59:59,999 stage. Yeah. My microphone. Ha ha. td: So, thanks. Just a quick look into the 556 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 557 99:59:59,999 --> 99:59:59,999 take the video from the C3VOC and put it through speech recognition just to get a 558 99:59:59,999 --> 99:59:59,999 rough transcript that we can then give to angels to actually correct, because, well, 559 99:59:59,999 --> 99:59:59,999 machine speech recognition doesn't work so good at all. And then once we have a 560 99:59:59,999 --> 99:59:59,999 working transcript that humans have looked at, we put that through auto-timing, which 561 99:59:59,999 --> 99:59:59,999 just takes the transcript and aligns that with the audio, and that usually works 562 99:59:59,999 --> 99:59:59,999 pretty well. And, well, once that is finished, then we actually have working 563 99:59:59,999 --> 99:59:59,999 subtitles, but we give them to angels for another round of review just to fix any 564 99:59:59,999 --> 99:59:59,999 mistakes that got overlooked. And maybe sometimes the timing needs to be adjusted. 565 99:59:59,999 --> 99:59:59,999 And then, when that is done, well, the subtitle is released. And actually one of 566 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 567 99:59:59,999 --> 99:59:59,999 sounds better, so thank you for that. Well, no presentation without graphs. As 568 99:59:59,999 --> 99:59:59,999 you can see, the important thing is really: everything goes up and to the 569 99:59:59,999 --> 99:59:59,999 right. On the bottom here we have finished seconds of transcribed talks. So this is 570 99:59:59,999 --> 99:59:59,999 really completed subtitles here. And it starts already quite high because it 571 99:59:59,999 --> 99:59:59,999 includes all the Congresses before. Then we have stuff that has been reviewed in 572 99:59:59,999 --> 99:59:59,999 orange. Stuff that has been timed but not reviewed yet in yellow. And transcribed 573 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 574 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 575 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 576 99:59:59,999 --> 99:59:59,999 from this Congress and then lots of hours worked. All of these numbers are at least 577 99:59:59,999 --> 99:59:59,999 as high as last year's numbers, so good, thanks. When you have transcripts, you can 578 99:59:59,999 --> 99:59:59,999 do cool stuff with that. So, for example, generate word clouds to see what people 579 99:59:59,999 --> 99:59:59,999 like. And this case, people seem to like people and questions and time, which we 580 99:59:59,999 --> 99:59:59,999 don't have any here. So. Well, how do we actually keep track of all this 581 99:59:59,999 --> 99:59:59,999 complicated stuff? Well, we use a state- of-the-art NoSQL lock-free columnar data 582 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 583 99:59:59,999 --> 99:59:59,999 for your hard work. And also thanks for the Heaven for supporting us. And then, 584 99:59:59,999 --> 99:59:59,999 well, if you if you feel bored between Congresses, you can still continue to work 585 99:59:59,999 --> 99:59:59,999 on transcripts. You have all the informations here, these slides will be 586 99:59:59,999 --> 99:59:59,999 online, follow us on Twitter. And thank you. 587 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 588 99:59:59,999 --> 99:59:59,999 H: Please do your thing again, like your thing again, like do *mimicks 589 99:59:59,999 --> 99:59:59,999 something*. Take your laptop. [Filler, please remove me in amara] 590 99:59:59,999 --> 99:59:59,999 *laughing* [Filler, please remove me in amara] 591 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 592 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 593 99:59:59,999 --> 99:59:59,999 very great care of everyone of us. So one of my highlights of every Congress, feel 594 99:59:59,999 --> 99:59:59,999 free, the LOC! LOC: Hello. I'm the stand-in for LOC. As 595 99:59:59,999 --> 99:59:59,999 with all good projects, they're too busy for documentation. They're packing. So LOC 596 99:59:59,999 --> 99:59:59,999 doesn't have anything. I'm more of the Department of Health and Safety again. So 597 99:59:59,999 --> 99:59:59,999 for everyone: we have the message from CERT that there were no work-related 598 99:59:59,999 --> 99:59:59,999 accidents that caused real harm. The odd broken Mate bottle maybe. But thank you 599 99:59:59,999 --> 99:59:59,999 for having built a city again safely and orderly, even with all the chaos. For the 600 99:59:59,999 --> 99:59:59,999 people who are driving, please make sure that the drugs wear off and that you get 601 99:59:59,999 --> 99:59:59,999 some sleep and for all people riding along, please keep the guys awake. That 602 99:59:59,999 --> 99:59:59,999 would be greatly appreciated. Go home safely. Thank you very much. 603 99:59:59,999 --> 99:59:59,999 *applause* [Filler, please remove me in amara] 604 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 605 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 606 99:59:59,999 --> 99:59:59,999 crew to not do overtime. So please, please give all the teams their respect and clap 607 99:59:59,999 --> 99:59:59,999 and tramp as loud as you can for now to finish! 608 99:59:59,999 --> 99:59:59,999 *standing ovation* [Filler, please remove me in amara] 609 99:59:59,999 --> 99:59:59,999 H: Everything! They did! For us! We did! For them! Why are you still sitting? You 610 99:59:59,999 --> 99:59:59,999 have to leave. Thank you. From the c3infrastructure Review. Goodbye. 611 99:59:59,999 --> 99:59:59,999 Subtitles created by many many volunteers and the c3subtitles.de team. Join us, and help us!
