Herald: Hello and welcome to[br]Infrastructure Review. This review is

0:00:23.510,0:00:28.080
being translated into a lot of languages[br]and we don't know yet which one, but the

0:00:28.080,0:00:35.020
c3lingo team will be on stage and will[br]tell us how and what it did. I'd like to

0:00:35.020,0:00:42.340
start, as always and every year, with the[br]NOC, right. So please give the NOC a hand.

0:00:42.340,0:00:48.130
*applause*[br][Filler, please remove me in amara]

0:00:48.130,0:00:54.810
Momo: All right, everyone, welcome to the[br]State of the Internet manufacture report.

0:00:54.810,0:00:58.850
This is JC, I'm Momo and we're going to[br]talk to you about what we did this year

0:00:58.850,0:01:05.730
for the network. So obviously, organizing[br]Congress is a quite tedious task. Took us

0:01:05.730,0:01:10.110
about six months of pre-planning. We came[br]in on the 15th, did a fiber day and then

0:01:10.110,0:01:14.500
it took us from the 18th and will take us[br]till tomorrow to tear everything down with

0:01:14.500,0:01:18.400
like 20 to 40 people. And we'll be busy[br]wiping every device because that is

0:01:18.400,0:01:21.470
actually what we do every year. We delete[br]everything. There are no logs leaving this

0:01:21.470,0:01:27.540
building and this will take us probably[br]the next 24 hours. So yeah, for the usual

0:01:27.540,0:01:31.610
numbers.  Edge capacity: this year because[br]you didn't use all the Internet last year,

0:01:31.610,0:01:36.520
we only brought you 300 gigs, but that was[br]fine as well, I suppose. We got 100 gig

0:01:36.520,0:01:40.620
from HLKomm here in Leipzig, 100 gig from[br]Deutsche Telekom and as well as 100 gig

0:01:40.620,0:01:48.479
from BCIX which we got via DWDM wave to[br]Berlin. In the core we used Juniper

0:01:48.479,0:01:56.549
MX960s, MX480s, MX204s and QFX10002 in the[br]yolocolo. Basically all the halls were

0:01:56.549,0:02:02.280
connected via a 200 gig link and yolocolo[br]had three times 100 gig. As probably the

0:02:02.280,0:02:09.330
last five or so years, we're using IS-IS[br]and BGP for our protocols of choice. And

0:02:09.330,0:02:13.860
this year we also first off rejected RPKI[br]invalid routes and secondly applied for

0:02:13.860,0:02:19.890
the first time at congress BCP38 ingress[br]filtering to be a good internet citizen

0:02:19.890,0:02:26.830
and not to allow you to spoof IP[br]addresses. So yeah, that was nice. As

0:02:26.830,0:02:31.330
Congress keeps on growing, we have 2500[br]tables somewhere around the building in

0:02:31.330,0:02:35.459
all the assemblies, but we only have 300[br]switches. So sorry if you had to bring a

0:02:35.459,0:02:40.401
long cable and if you have switches to[br]spare with 10 gig uplinks and POE+, feel

0:02:40.401,0:02:47.530
free to donate them to us. Access and Wi-[br]Fi. We had like 300 access switches. We

0:02:47.530,0:02:51.330
are obviously again running Aruba Wi-Fi[br]controllers. This year, like at camp we

0:02:51.330,0:02:57.630
had a few 802.1x access points, more on[br]that later. We tried to use Juniper vMX to

0:02:57.630,0:03:03.000
route the Wi-Fi traffic. And had quite a[br]shitload of switches, most of them from

0:03:03.000,0:03:08.849
Juniper, some Cisco 2960s, some Brocades[br]which are new to us, and some crappy old

0:03:08.849,0:03:13.470
HPE stuff which is basically configured[br]for us to work like a brick you get from

0:03:13.470,0:03:18.610
like eBay or whatnot. We had a few[br]incidents this year we'd like to talk

0:03:18.610,0:03:23.150
about. First off, we had, I'm not sure if[br]any of you noticed, quite a lot of packet

0:03:23.150,0:03:28.560
loss and missing router advertisements on[br]the Wi-Fi. This was caused by some weird

0:03:28.560,0:03:32.780
Juniper vMX behavior. We couldn't figure[br]out what it was. So we had them running in

0:03:32.780,0:03:38.739
a redundant VRRP setup. We shut down one[br]of them and then it worked. So yeah, fuck

0:03:38.739,0:03:45.239
redundancy. There was a pixelflut client[br]which somehow messed up his IP address and

0:03:45.239,0:03:52.650
caused a broadcast storm which took down[br]most parts of Hall 2. We found them, shut

0:03:52.650,0:03:59.671
it down and deployed storm control to all[br]our access switches. Yeah, to the Congress

0:03:59.671,0:04:06.120
motto resource exhaustion: someone was[br]running aggressive zmap scanning over the

0:04:06.120,0:04:10.989
whole internet, came by our Wi-Fi access[br]controller and caused a state table

0:04:10.989,0:04:15.620
exhaustion. And that brought it down. We[br]null-routed the source and yeah, there was

0:04:15.620,0:04:23.990
this issue. So thank you to whoever was[br]that. And in the morning of day 3, we had

0:04:23.990,0:04:27.890
another issue with Juniper vMX where it[br]forgot it had a network card. We rebooted

0:04:27.890,0:04:33.139
it and everything was fine again. So yeah,[br]some numbers. You actually managed to use

0:04:33.139,0:04:39.340
more bandwidth, thank you.[br][Filler, please remove me in amara]

0:04:39.340,0:04:43.380
*applause*[br][Filler, please remove me in amara]

0:04:43.380,0:04:47.830
M: But it's still only 20% of our uplink[br]capacity. So use more. 20% of that was

0:04:47.830,0:04:53.650
IPv6, which is good, but could be more. We[br]had like 11000 clients into Wi-Fi.  86% 5

0:04:53.650,0:05:02.240
GHz, 96% in a peak.[br]We had eleven 802.11ax clients. Our

0:05:02.240,0:05:09.240
favorite one was obviously the one with[br]the lovely hostname ILOVETHENOC. So yeah,

0:05:09.240,0:05:14.919
about that number we have, 96% 5 GHz[br]obviously shows us that we are finally at

0:05:14.919,0:05:20.440
the point where we can say: thank you 2.4[br]GHz, it was nice. Goodbye.

0:05:20.440,0:05:24.919
*applause*[br][Filler, please remove me in amara]

0:05:24.919,0:05:32.240
M: Also, obviously, thank you to our[br]sponsors. We couldn't do this if we would

0:05:32.240,0:05:37.110
not get like 10 millions, of list price[br]obviously, of equipment and loan and quite

0:05:37.110,0:05:40.350
a lot of services. So give them a round of[br]applause as well. Thank you.

0:05:40.350,0:05:46.389
*applause*[br][Filler, please remove me in amara]

0:05:46.389,0:05:50.889
M: And obviously NOC not only stands for[br]Network Operation Center, but if you

0:05:50.889,0:05:55.870
extend it, it is No CO2. So we believe in[br]green power and clean traffic and

0:05:55.870,0:06:01.039
therefore we obviously see that[br]sustainability is a great part of our

0:06:01.039,0:06:05.420
role. This is why we even use old crappy[br]HP switches to cut our lines for our

0:06:05.420,0:06:07.919
tchunk to serve your cheese boards,[br]whatever you need.

0:06:07.919,0:06:10.400
*laughter*[br][Filler, please remove me in amara]

0:06:10.400,0:06:13.240
M: Also...[br][Filler, please remove me in amara]

0:06:13.240,0:06:15.729
*applause*[br][Filler, please remove me in amara]

0:06:15.729,0:06:21.270
M: Also, we somehow estimated what our[br]network will run us in CO2 and that was

0:06:21.270,0:06:26.229
about 11 tons. We're not very good with[br]mass and not very good with CO2 emissions,

0:06:26.229,0:06:31.410
but this was roughly what we came up with.[br]And to make Congress or the world a bit

0:06:31.410,0:06:40.970
better place, we actually offset all our[br]CO2 and bought eleven tons of CO2

0:06:40.970,0:06:49.419
emissions. And now Frederick is gonna tell[br]you how we got all those numbers.

0:06:49.419,0:06:54.849
Frederick: Yeah, as a good internet[br]manufacture, we also do monitoring a lot

0:06:54.849,0:07:00.069
and we run our own Prometheus server[br]inside. You probably know the dashboard

0:07:00.069,0:07:06.300
that we propagate all over the internet[br]and that's powered by Prometheus. We have

0:07:06.300,0:07:12.250
an internal Grafana that is part of this[br]whole ecosystem. And if you are a little

0:07:12.250,0:07:16.000
bit of a nerd, you might have clicked on[br]the dashboard sections and seen that there

0:07:16.000,0:07:23.420
are more dashboards than this. We fill our[br]Prometheus with lots of different sources:

0:07:23.420,0:07:30.080
we get SNMP data from, and screw SNMP, but[br]it does a quite good job at getting all

0:07:30.080,0:07:34.740
the insights we need from all the network[br]equipment. We have node_exporter, influx

0:07:34.740,0:07:40.650
and all that, but we got a decent amount[br]of data from everyone in the Congress

0:07:40.650,0:07:45.699
ecosystem and we had that at camp as well[br]where we got the water pressure of the

0:07:45.699,0:07:52.169
showers. And we get the colo power, which[br]also helps with estimating the CO2

0:07:52.169,0:07:58.190
footprint. And everything is being[br]configured by Netbox, which is a tool that

0:07:58.190,0:08:06.139
is an asset database. And as I said, we[br]have lots of dashboards and graphs. Of

0:08:06.139,0:08:09.660
course, the public one where you can see[br]lots of different things from everyone.

0:08:09.660,0:08:15.950
This is only part of it. If you scroll[br]down on the dashboard, you see a lot more.

0:08:15.950,0:08:19.319
But this helps everyone to have a good[br]understanding of what is happening

0:08:19.319,0:08:23.669
currently. And we even draw a nice little[br]Christmas trees on the Wi-Fi traffic for

0:08:23.669,0:08:28.270
you. That is mostly because it's a router-[br]on-a-stick and we cannot measure it

0:08:28.270,0:08:32.570
correctly. We have an internal dashboard[br]which gives us a little bit of a status

0:08:32.570,0:08:40.120
for build-up mostly: which switches and[br]routers are up? And that gives us a very

0:08:40.120,0:08:45.620
quick sight of all the devices that are[br]out there. What's broken? What's not

0:08:45.620,0:08:50.070
broken? We improved it a little and now[br]have alarms so someone can look at stuff

0:08:50.070,0:08:58.540
and see if things are broken, run out[br]there and fix it. We also built

0:08:58.540,0:09:03.850
weathermaps. As you can see that's a[br]little bit of a mess. But we couldn't do

0:09:03.850,0:09:11.459
it better because the graphing library[br]doesn't allow us to do it better. If

0:09:11.459,0:09:16.029
someone has a good idea to do it better in[br]Grafana or anywhere else with sources from

0:09:16.029,0:09:21.370
Prometheus, please come to us, we're happy[br]to talk. But this shows our core and all

0:09:21.370,0:09:26.399
the links between it and how much capacity[br]is being used. Red indicates that it's

0:09:26.399,0:09:32.980
used more heavily. We also have that for[br]the yolocolo. And all the traffic around

0:09:32.980,0:09:41.149
it as well. And, yeah, teardown starts[br]now. Please don't touch our equipment. And

0:09:41.149,0:09:45.709
if you want to come and help, please come[br]to Hall 4 and get in touch. We always need

0:09:45.709,0:09:50.089
helping hands. But please in an organized[br]way don't disassemble switches or access

0:09:50.089,0:09:56.220
points. We have lists and everything. We[br]need to account for everything. So please

0:09:56.220,0:09:59.970
come to Hall 4 if you want to help. And[br]yes, use more bandwidth and offset more

0:09:59.970,0:10:03.930
CO2. Thank you.[br][Filler, please remove me in amara]

0:10:03.930,0:10:06.029
*applause*[br][Filler, please remove me in amara]

0:10:06.029,0:10:11.399
H: So thanks a lot. Actually, because[br]you're clearly the backbone or one of

0:10:11.399,0:10:15.950
those many backbones of the conference, is[br]there any Q? Let's do a Q&A for like one

0:10:15.950,0:10:18.769
or two questions.[br]Is anyone having a question right now?

0:10:18.769,0:10:23.390
Someone is standing up. Right, microphone[br]number one, please.

0:10:23.390,0:10:26.930
Q: Hey, we've absolutely don't ...[br][Filler, please remove me in amara]

0:10:26.930,0:10:28.930
H: Nearer, nearer.[br][Filler, please remove me in amara]

0:10:28.930,0:10:33.670
Q:  We've absolutely done bcp38 in[br]previous years, by the way.

0:10:33.670,0:10:37.730
M: Sorry for what I said then, I'm sorry.[br]Q: So I wanted to correct the record.

0:10:37.730,0:10:40.920
We've been good netizens in previous years[br]as well.

0:10:40.920,0:10:46.399
H: Oh, you're right. Thank you. Was there[br]another question or something else to

0:10:46.399,0:10:49.020
correct them? Because they clearly don't[br]know what they're doing.

0:10:49.020,0:10:50.830
*laughter*[br][Filler, please remove me in amara]

0:10:50.830,0:10:57.010
H: Yeah. Feel free. Microphone number two.[br]Q: So if 2.4GHz is over, what's going to

0:10:57.010,0:11:02.450
happen to all of the ESP32 in various IoT[br]devices? Are they going to have a home

0:11:02.450,0:11:06.260
here next year?[br]M: They'll definitely have a home. But as

0:11:06.260,0:11:09.390
usual, we cannot support it as good as we[br]can on 5GHz because obviously this band is

0:11:09.390,0:11:17.860
overused and not even remotely suited for[br]that amount of clients we put on it.

0:11:17.860,0:11:24.820
Q: A follow-up for the ESP32. How exactly[br]can you locate them through the wireless

0:11:24.820,0:11:31.150
if they are lost?[br]M: Well, we can't. We can basically look

0:11:31.150,0:11:34.820
at which access point they are, and then[br]if someone really would want to, we could

0:11:34.820,0:11:38.610
start triangulation, but we've never done[br]that before. So yeah, we can just pin them

0:11:38.610,0:11:46.120
roughly to an access point.[br]H: Maybe we can ask c3nav next time. So

0:11:46.120,0:11:49.560
please give the NOC a hand.[br]Thank you.

0:11:49.560,0:11:52.389
*applause*[br][Filler, please remove me in amara]

0:11:52.389,0:11:59.639
H: So, the next team up is the POC. Do we[br]have to click this? Use more bandwidth,

0:11:59.639,0:12:04.770
I'm going to try. Ah! Thank you. Your[br]stage.

0:12:04.770,0:12:07.990
Garvin: Thanks.[br][Filler, please remove me in amara]

0:12:07.990,0:12:11.590
*applause*[br][Filler, please remove me in amara]

0:12:11.590,0:12:14.060
Maria: Hi, my name is Maria.[br][Filler, please remove me in amara]

0:12:14.060,0:12:17.950
G: Hi, and I'm Garvin and we're from Phone[br]Operation Center and we want to talk a bit

0:12:17.950,0:12:20.850
about the phone infrastructure at this[br]event.

0:12:20.850,0:12:27.420
M: Yeah. So we arrived at day -6 and[br]planned on hacking some things

0:12:27.420,0:12:34.100
and socializing and we planned a team[br]event, but then everything was different.

0:12:34.100,0:12:40.079
G: Yeah. When we arrived, I went into the[br]NOC office and they said to me, "Ja, CCL

0:12:40.079,0:12:44.490
is up, internet is up, everything is just[br]working nicely. You can start hook up your

0:12:44.490,0:12:51.050
telephony system right now." And I was[br]like, whoa. So thanks a lot NOC. Really

0:12:51.050,0:12:54.810
great performance this year, we were[br]amazed. Nobody expected that it works so

0:12:54.810,0:12:57.970
well.[br][Filler, please remove me in amara]

0:12:57.970,0:13:01.140
*applause*[br][Filler, please remove me in amara]

0:13:01.140,0:13:06.399
M: Yeah. So we put up the first antennas[br]and then we decided to have our team event

0:13:06.399,0:13:16.399
anyway. And yeah, so we did a lot of[br]things. So we handed out 150 orga loan

0:13:16.399,0:13:26.621
DECTs and we deployed 51 SIP telephones.[br]We also deployed 67 antennas and we had a

0:13:26.621,0:13:32.690
POC party on day three until 7:30 a.m.[br]G: So you can see almost everything is

0:13:32.690,0:13:40.170
done. I guess the remaining things are not[br]that important. So this is the overview of

0:13:40.170,0:13:45.459
DECT coverage at the event. Only level[br]zero, because otherwise I think it would

0:13:45.459,0:13:50.839
be overcrowded to show. Just so that you[br]can get a rough impression on how many

0:13:50.839,0:13:55.650
antennas we deployed in order to give you[br]this DECT coverage. That you can be

0:13:55.650,0:14:00.130
reached almost everywhere in the event and[br]that you can see how our tooling looks

0:14:00.130,0:14:04.460
like, where we see how good the antennas[br]see each other, and that we can see that

0:14:04.460,0:14:10.279
seamless handover work so that you can[br]start at our desk, walk through the area,

0:14:10.279,0:14:16.380
into the lounge and just continue talking.[br]And oh, there are also some antennas that

0:14:16.380,0:14:19.930
are outside of the building. What could[br]that be?

0:14:19.930,0:14:25.759
M: That is our hotel DECT. And you can see[br]a typical hotel DECT installation on the

0:14:25.759,0:14:32.250
photo. And people got really confused[br]about it because we also had DECT coverage

0:14:32.250,0:14:37.230
at main station.[br]G: Yeah. So I got a call roughly at 4:00

0:14:37.230,0:14:39.230
p.m. in the morning.[br][Filler, please remove me in amara]

0:14:39.230,0:14:43.589
*applause*[br][Filler, please remove me in amara]

0:14:43.589,0:14:50.150
G: And somebody told me. Oh, my DECT rang.[br]Why? Now I need to turn it off at the

0:14:50.150,0:14:57.720
night. Why did you do this?[br]M: Yeah. So we also had problems. We have

0:14:57.720,0:15:04.190
a new feature since Camp where you can see[br]your DECT devices and can assign them to

0:15:04.190,0:15:07.680
your number before you even arrive, and[br]then everything is set up and you don't

0:15:07.680,0:15:12.450
have to call your token anymore. And[br]people get really confused because they

0:15:12.450,0:15:17.920
would call their token anyway and it calls[br]it invalid. So we had to explain a lot of

0:15:17.920,0:15:26.680
this unexpected simplicity to them.[br]G: And then we had a battery issue this

0:15:26.680,0:15:31.870
year. We had not enough batteries and, you[br]know, batteries are always empty in the

0:15:31.870,0:15:37.010
phones when it's the most important. So we[br]were thinking what what can we do about

0:15:37.010,0:15:41.070
that?[br]M: So we build a new device. That's our

0:15:41.070,0:15:49.640
microwave and it can also charge devices.[br]So, many thanks to C3Power, because they

0:15:49.640,0:15:55.050
helped us with tooling and actually they[br]have expertise to put power cables on

0:15:55.050,0:16:04.002
devices like this. Thank you very much.[br][Filler, please remove me in amara]

*applause*[br][Filler, please remove me in amara]

0:16:05.002,0:16:08.810
G: In the last years we were often asked[br]"how expensive is your service actually?".

0:16:08.810,0:16:13.449
So we decided that we now provide invoices[br]so you can see how expensive our services

0:16:13.449,0:16:21.579
are and we send out a lot of invoices. And[br]we got paid some money. But as you can see

0:16:21.579,0:16:28.329
on the invoices, most is sponsored by CCC.[br]M: Yeah. And people also paid with Mate

0:16:28.329,0:16:34.560
which is really awesome.[br]G: Yeah. And also people have invoices on

0:16:34.560,0:16:39.230
a fraction of a cent and they got quite[br]creative on how they can pay us.

0:16:39.230,0:16:46.460
*laughter*[br][Filler, please remove me in amara]

0:16:46.460,0:16:51.930
*applause*[br][Filler, please remove me in amara]

0:16:51.930,0:16:54.569
M: So here are some more stats. We have[br]7473 registered extensions.

0:16:54.569,0:16:58.290
G: Oh, we didn't remove this. So we were[br]thinking on how to compare this with

0:16:58.290,0:17:02.779
things and we were looking at villages in[br]Saarland and then we thought, this is a

0:17:02.779,0:17:05.959
stupid comparison, but we didn't remove[br]this.

0:17:05.959,0:17:17.199
M: So there were 5021 attached DECT phones[br]and 3251 concurrent DECT phones. Which is

0:17:17.199,0:17:21.920
about more than 1000 more than last year.[br]G: So thanks a lot for using DECT.

0:17:21.920,0:17:25.390
M: Yeah. We had...[br][Filler, please remove me in amara]

0:17:25.390,0:17:27.309
*applause*[br][Filler, please remove me in amara]

0:17:27.309,0:17:36.150
M: There were also max 120 calls in[br]parallel, and we had more than 300

0:17:36.150,0:17:43.890
thousand calls in total. That's also[br]really, really much. We had five eating

0:17:43.890,0:17:52.900
meetings at heaven, the angel eating[br]place, and there were an average of 42

0:17:52.900,0:18:01.270
eating meeting live viewers. We had two[br]lectures. You can see them on media.ccc.de

0:18:01.270,0:18:05.490
and we had 23 super fast charged phones in[br]our microwave.

0:18:05.490,0:18:11.930
*applause*[br][Filler, please remove me in amara]

0:18:11.930,0:18:17.580
G: Like the NOC, we also had to deal a bit[br]with issues during the event, and actually

0:18:17.580,0:18:24.870
there were some DDOS attack on our account[br]system and somebody configured over 4000

0:18:24.870,0:18:29.130
extensions with really stupid names. And[br]it took us quite a while to get rid of

0:18:29.130,0:18:33.210
them again cleanly from the system because[br]the synchronization turned out to be

0:18:33.210,0:18:39.660
really slow. So you can see it took us a[br]while to get them removed again. So we can

0:18:39.660,0:18:44.330
only say, you all know it's a hacker[br]congress, but it's kind of stupid to hack

0:18:44.330,0:18:48.620
your own infrastructure.[br][Filler, please remove me in amara]

0:18:48.620,0:18:51.850
*applause*[br][Filler, please remove me in amara]

0:18:51.850,0:18:58.480
G: So as a consequence of this, we only[br]allow now only 50 extensions per account

0:18:58.480,0:19:03.040
and per event. If you think you need more,[br]feel free to contact us if you have a

0:19:03.040,0:19:06.530
valid use case.[br][Filler, please remove me in amara]

0:19:06.530,0:19:12.640
M: So every device has an IPEI that is[br]like a MAC address and we ask the

0:19:12.640,0:19:19.090
responsible institution to give us the[br]manufacturer. But it's really secret. So

0:19:19.090,0:19:23.240
they don't give it to us. So we ask you[br]for help. Please enter the models of your

0:19:23.240,0:19:29.260
devices for your phones. And then we can[br]match to the IPEI and get some data to

0:19:29.260,0:19:32.990
build more awesome features for you.[br][Filler, please remove me in amara]

0:19:32.990,0:19:37.391
G: This would really help us. And the only[br]way for us is to crowdsource it because it

0:19:37.391,0:19:40.650
seems to be super secret. Whatever.[br][Filler, please remove me in amara]

0:19:40.650,0:19:45.570
M: You can find it in guru3 on the device[br]page and there's this little pen. And if

0:19:45.570,0:19:49.350
you click on it, then you can enter the[br]model.

0:19:49.350,0:19:57.610
G: Thanks upfront. And yep, that's from[br]us, and I guess now we have a little time

0:19:57.610,0:20:01.500
for you to ask questions.[br][Filler, please remove me in amara]

0:20:01.500,0:20:04.909
*applause*[br][Filler, please remove me in amara]

0:20:04.909,0:20:13.880
H: Great. So, any questions for the POC? I[br]don't see... were they correct or do we

0:20:13.880,0:20:20.240
have to...? Ah, someone is getting up. So[br]microphone number 1, please.

0:20:20.240,0:20:25.150
Q: Yes, a few years ago there was a[br]translation service via DECT. Is the

0:20:25.150,0:20:29.830
capacity enough to service also this[br]crowd?

0:20:29.830,0:20:36.560
G: The problem is that we switched the[br]phone system a while ago last year at the

0:20:36.560,0:20:43.820
Congress. And the old phone system had a[br]way how we can do the translation via one

0:20:43.820,0:20:48.510
channel and the problem is that the new[br]system doesn't support this. Let me say

0:20:48.510,0:20:55.120
the new system doesn't support it yet. So[br]have a look at our talk and then you can

0:20:55.120,0:21:01.690
see that there is some potential.[br]H: I see someone at microphone number 3,

0:21:01.690,0:21:05.140
please. This would be the last question[br]because we have to hurry a bit.

0:21:05.140,0:21:10.080
Q: Can I know a little bit more about the[br]super charging microwave? I'm confused.

0:21:10.080,0:21:14.330
*applause*[br][Filler, please remove me in amara]

0:21:14.330,0:21:20.550
M: Sure, you can come to our POC desk and[br]then we answer all your questions.

0:21:20.550,0:21:28.780
H: Ooh... mystery.  Please, give the POC a[br]hand.

0:21:28.780,0:21:39.940
So next team, is it from the GSM crew?[br]Someone there? I think we have two. I see

0:21:39.940,0:21:44.919
some Chaos Post, you have to wait one[br]round. So, GSM guy thank you. I am good

0:21:44.919,0:21:53.500
with computers, I think. Yeah, I am. Have[br]fun. If it's working or not. Look at this

0:21:53.500,0:22:03.679
smile then looks better. Try this. Yeah.[br]Right. Try this.

0:22:03.679,0:22:09.849
- 423.[br]- Maybe you have to use GSM.

0:22:09.849,0:22:13.599
- 23 test.[br]- What happened?

0:22:13.599,0:22:16.599
- Hello. Hello.[br]- Aah.

0:22:16.599,0:22:24.630
GSM Person 1: So as every year we ran our[br]own mobile phone network at the Congress

0:22:24.630,0:22:32.620
using osmocom open source software for 2G[br]and 3G, and open5gs interfacing with the

0:22:32.620,0:22:37.909
osmocom HLR. And all you need to take part[br]is a SIM card that you can buy from the

0:22:37.909,0:22:47.250
POC and for 5 euros you get a flat rate.[br]The price increases because we have less

0:22:47.250,0:22:53.150
SIM cards every year. We need to[br]manufacture new ones. You can even call

0:22:53.150,0:23:02.830
outside like you can with DECT phones.[br]Lynxis: Hello. I'm Lynxis. So as every

0:23:02.830,0:23:09.450
year for the GSM team, the first problem[br]is the license. That's the first step

0:23:09.450,0:23:16.539
usually. Because in Germany, you have to[br]get the official form, get a license but

0:23:16.539,0:23:22.510
... Where do you get it? What can you ask[br]for frequencies? Because, for example, the

0:23:22.510,0:23:28.940
POC for DECT or Wi-Fi, you just place it[br]and you can use it. You're fine.

0:23:28.940,0:23:35.480
But for GSM, they didn't think about it or[br]for 3G or 4G. So yeah, this year we

0:23:35.480,0:23:41.520
usually get the license middle of[br]december, maybe start of december. So it's

0:23:41.520,0:23:51.380
already late. So this year we didn't get[br]all our licenses. But we get some. We got

0:23:51.380,0:23:59.409
850 MHz, which is not assigned in Europe[br]because it's usually in the US only. But

0:23:59.409,0:24:06.760
we have a small hole. This year we got a[br]4G license instead of a 2G license with 10

0:24:06.760,0:24:11.640
Mhz from Telefonica. So thanks Telefonica[br]for borrowing us spectrum.

0:24:11.640,0:24:18.780
*applause*[br][Filler, please remove me in amara]

0:24:18.780,0:24:24.080
L: Just a short example of how the[br]spectrum looks like. The yellow stuff is

0:24:24.080,0:24:31.830
usually somewhere behind actually. By the[br]way, this microphone, it might share the

0:24:31.830,0:24:36.450
same frequency with us. But so far, we[br]haven't found any interference together

0:24:36.450,0:24:45.770
with the VOC. Down there you can see the[br]small hole which we are using. Because we

0:24:45.770,0:24:51.850
didn't get the 2G license there, we[br]thought, OK. Let's take a look. Can we fit

0:24:51.850,0:24:56.919
them both in the same frequencies? It's[br]not good. But you see the spikes, this

0:24:56.919,0:25:03.880
nice antenna on the right. That's the GSM,[br]which is sending on the same frequency. It

0:25:03.880,0:25:07.250
works because they are using different[br]codings. But I have heard from people who

0:25:07.250,0:25:10.039
know more about it, this is not the way[br]you use it.

0:25:10.039,0:25:13.289
*laughing*[br][Filler, please remove me in amara]

0:25:13.289,0:25:17.830
L: So we took some photos of our base[br]stations. This is actually the fairy dust

0:25:17.830,0:25:23.909
from the 2G base station, so we have a[br]idea what we are using here. We have even

0:25:23.909,0:25:31.200
more fairy dust in our 3G femtocells and[br]our 4G cells. They are looking like small

0:25:31.200,0:25:37.600
toasters. They are taking actually 90[br]watts via POE, they have special POE

0:25:37.600,0:25:44.740
adapters. So maybe we could ask if[br]somebody can do a similar adapter to get

0:25:44.740,0:25:52.770
even running a toaster on the line.[br]So basically for the 4G setup this year,

0:25:52.770,0:25:57.830
we weren't sure if it's stable enough or[br]we lose all our phones to the LTE and they

0:25:57.830,0:26:05.960
don't like to come back to the 2G and 3G[br]setup where we have voice, because on LTE

0:26:05.960,0:26:10.590
we don't have yet voice so you have to[br]select specifically to join the LTE

0:26:10.590,0:26:16.919
network. That worked quite fine if you[br]change it. So your phone will register.

0:26:16.919,0:26:24.299
Everything fine there.[br]GSM1: So the rollout this year: we had the

0:26:24.299,0:26:30.690
voice working on day 0 which is new.[br][Filler, please remove me in amara]

0:26:30.690,0:26:34.710
*applause*[br][Filler, please remove me in amara]

0:26:34.710,0:26:41.760
GSM1: Someone even noticed on Mastodon, I[br]saw it, too. We already had LTE at the CCC

0:26:41.760,0:26:48.441
camp this year. Yeah, but unfortunately we[br]lost crypto password, so LTE roll out took

0:26:48.441,0:26:59.860
a bit longer this time. Sorry. So some[br]numbers. In total we saw just about 1100

0:26:59.860,0:27:06.490
people doing a location updating on our[br]network and 845 eventphone tokens were

0:27:06.490,0:27:15.620
dialed on the GSM. That is 2G or 3G. And[br]there were roughly 200 phones actively

0:27:15.620,0:27:21.110
subscribed on the network at all times.[br]And even though we basically only deployed

0:27:21.110,0:27:29.240
3G nano stations in all the halls and only[br]had two 2G BTS in the glass halle, there

0:27:29.240,0:27:35.390
were roughly more than half of all the[br]phones were still subscribed on 2G instead

0:27:35.390,0:27:43.169
of 3G. We had like 18 3G stations and only[br]two plus one in the GSM room 2G stations.

0:27:43.169,0:27:50.799
So that's a bit surprising. And SIM cards:[br]starting from the bottom, we sold about

0:27:50.799,0:27:56.909
700 SIM cards, but only saw half of them[br]activated, which is curious. And luckily,

0:27:56.909,0:28:02.320
most or some people bring old SIM cards[br]from previous years. And it's not so easy

0:28:02.320,0:28:07.640
to get cards manufactured. So we are very[br]glad for everyone who brings old SIM cards

0:28:07.640,0:28:14.460
from previous events. We might even[br]consider introducing charging phone calls

0:28:14.460,0:28:18.890
only for SIM cards that are newly bought.[br]So if you want to continue calling for

0:28:18.890,0:28:22.950
free, rather bring your old SIM cards.[br][Filler, please remove me in amara]

0:28:22.950,0:28:25.350
*applause*[br][Filler, please remove me in amara]

0:28:25.350,0:28:31.190
GSM1: So you see the numbers, I'm not[br]going to go through them. And you can also

0:28:31.190,0:28:40.130
get the ADM, the admin keys for your SIM[br]cards if you like to write to them.

0:28:40.130,0:28:46.850
L: Or if you have seen the talk from[br]LaForge, you might want to play with the

0:28:46.850,0:28:53.140
SIM cards, we give out all the keys you[br]want to have to play with it.

0:28:53.140,0:29:02.640
GSM1: So operation was mostly smooth,[br]except iPhones, for unknown reasons. And

0:29:02.640,0:29:06.401
except the data service, which might even[br]be related because maybe Apple is a bit

0:29:06.401,0:29:12.150
more strict on whether data service is[br]working reliably. Yeah, we still had some

0:29:12.150,0:29:18.360
problems in the SGs instance introducing[br]3G changing between the radio access

0:29:18.360,0:29:25.559
technologies. It's a whole new ballgame so[br]there are still some bugs in there. And as

0:29:25.559,0:29:30.480
you see, we had many more tickets than the[br]POC. This is actually reversed from the

0:29:30.480,0:29:37.330
POC, the "done" is on the left. So this[br]whole bunch of stuff is done and there's

0:29:37.330,0:29:45.010
some backlog and canceled and fantasy[br]tasks. It worked pretty nicely. Are you

0:29:45.010,0:29:50.799
taking over? Oh, yeah, no, this is still[br]mine. And this year we actually had also a

0:29:50.799,0:29:56.519
denial of service attack. The code was the[br]same as previous years and we never saw

0:29:56.519,0:30:01.770
this before. But this year we got an[br]invalid mobile identity which managed to

0:30:01.770,0:30:06.429
crash our mobile switching center. And[br]thank you very much for uncovering this

0:30:06.429,0:30:12.669
bug and thanks to fixeria for fixing it on[br]day 2. Ever since the mobile switching

0:30:12.669,0:30:19.820
center for Voice and SMS and subscription[br]has been running stable.

0:30:19.820,0:30:30.899
*applause*[br][Filler, please remove me in amara]

0:30:30.899,0:30:38.120
L: Maybe some interference. We recovered[br]the old phones again. Last year we

0:30:38.120,0:30:41.500
couldn't support them. But we managed to[br]implement the missing parts. Old phones

0:30:41.500,0:30:46.360
could work if they support the[br]frequencies. So that's really nice. Maybe

0:30:46.360,0:30:54.880
next time. Since camp, we also did a nice[br]angel helpdesk. And it was really

0:30:54.880,0:31:00.000
impressive to see that we even had to add[br]more shifts in our shifts. We had so many

0:31:00.000,0:31:06.000
motivated angels. Thanks to everybody who[br]helped us, it was really great.

maybe nine. So we need to speed up a bit.[br]Our next team for now will be... We don't

0:31:39.940,0:31:42.840
have working microphones.[br]Chaos post 1: Sorry, we need to interrupt

0:31:42.840,0:31:46.840
you anyway.[br]H: OK. So tell them, chaos post! Chaos

0:31:46.840,0:31:48.840

Chaos post 1: Sorry, guys, we interrupt...[br][Filler, please remove me in amara]

0:31:54.590,0:31:59.149
H: Let's get rid of the broken one because[br]it's not working anyway.

0:31:59.149,0:32:03.820
Chaos post 1: All right. Sorry, we are[br]interrupting for a few minutes only. We

0:32:03.820,0:32:07.290
would like to deliver a few statistics as[br]well. So thanks of all, we had multiple

0:32:07.290,0:32:14.070
chaos deliverers working throughout the[br]whole Congress 24/7 basically, delivering

0:32:14.070,0:32:18.710
at the speed of chaos, as our mission[br]statement clearly states. So thank you

0:32:18.710,0:32:21.549
therefore, first of all thank you very[br]much to all of you who contributed to

0:32:21.549,0:32:24.149
that.[br][Filler, please remove me in amara]

0:32:24.149,0:32:26.750
*applause*[br][Filler, please remove me in amara]

0:32:26.750,0:32:31.770
Chaos post 2: So let's have some numbers,[br]because you all love numbers, right? So we

0:32:31.770,0:32:38.049
delivered about 3000 external postcards.[br]So that means with like outside chaos, so

0:32:38.049,0:32:44.280
to the real world or the default world, as[br]we call it. We delivered those to over 42

0:32:44.280,0:32:49.250
countries all over the world. So you guys[br]are really good connected internationally.

0:32:49.250,0:32:57.549
And also, we don't have exact numbers, but[br]we estimate around 3500, no, 35000,

0:32:57.549,0:33:07.909
internal postcards. And you also use our[br]online office for a total of 789 times. So

0:33:07.909,0:33:12.630
that is only 15 less than camp, and that[br]was a longer event. So, hey, you guys

0:33:12.630,0:33:16.200
write a lot of postcards![br][Filler, please remove me in amara]

0:33:16.200,0:33:19.049
*applause*[br][Filler, please remove me in amara]

0:33:19.049,0:33:23.730
Chaos post 1: As you might already know[br]from camp, we also do have a few special

0:33:23.730,0:33:29.360
services. As already on camp, we had the[br]serving proposal, basically a pre-

0:33:29.360,0:33:34.490
assembled text, you just had to cross what[br]you want. The postbox certification and of

0:33:34.490,0:33:38.620
course, the bi-directional chaos, in[br]Germany also known as "Einschreiben mit

0:33:38.620,0:33:40.620
Rückschein".[br]H: Wow.

0:33:40.620,0:33:45.870
Chaos post 2: And this time we also[br]offered some new services. We had like

0:33:45.870,0:33:51.149
sang telegrams, gesunges Telegram in[br]Deutsch. We had a forever alone box for

0:33:51.149,0:33:56.809
people wanting to write postcards with or[br]exchange postcards with no idea who to

0:33:56.809,0:34:02.100
write it to. We had love letters, so we[br]had some nice pre-assembled texts and also

0:34:02.100,0:34:07.760
a really nice selection of perfumes for[br]scented postcards. You could write some

0:34:07.760,0:34:12.919
secret messages. We had some UV pens and[br]also we had some, let's say call it

0:34:12.919,0:34:17.679
security, or rather temper evidence,[br]because we had some scratch off stickers

0:34:17.679,0:34:23.570
for you. And also we had over 30 new[br]postcard designs that you could use for

0:34:23.570,0:34:25.570
postcards.[br][Filler, please remove me in amara]

0:34:25.570,0:34:26.820
*applause*[br][Filler, please remove me in amara]

0:34:26.820,0:34:30.679
Chaos post 1: Short remark for the love[br]letters and the perfumes. Well, that was

0:34:30.679,0:34:39.329
kind of not really thought through. It was[br]a bit... it was fun sorting them out, and

0:34:39.329,0:34:42.950
stamping all of that, smelling all the[br]perfume all the time.

0:34:42.950,0:34:46.419
Chaos post 2: And then brushing your hands[br]really thoroughly because, well, that

0:34:46.419,0:34:51.899
stuff gets on your hands when you do that.[br]Chaos post 1: Also for UV pens. Just a

0:34:51.899,0:34:55.280
little remark. It's not a good idea to use[br]it for addressing and the message.

0:34:55.280,0:34:57.560
*laughing*[br][Filler, please remove me in amara]

0:34:57.560,0:35:04.099
Chaos post 1: You can take the risk. All[br]right, then let me close up. We also

0:35:04.099,0:35:08.869
supported mail  this year and[br]we had 130 letters for activists in

0:35:08.869,0:35:13.220
prison, which I find really great. I think[br]that's something we can all support.

0:35:13.220,0:35:16.349
Amazing.[br][Filler, please remove me in amara]

0:35:16.349,0:35:19.490
*applause*[br][Filler, please remove me in amara]

0:35:19.490,0:35:25.070
So thank you all for this amazing event,[br]and have some fun for the rest of the

0:35:25.070,0:35:27.070
Congress.[br][Filler, please remove me in amara]

0:35:27.070,0:35:29.010
*applause*[br][Filler, please remove me in amara]

0:35:29.010,0:35:40.380
H: Chaos post! So the next team is the[br]VOC. Yes, you can have it. Here, the VOC.

0:35:40.380,0:35:45.410
We only have 20 minutes left in total for[br]every team. So you know what to do.

0:35:45.410,0:35:54.579
VOC1: Hurry up. Welcome, guys. So. Yeah.[br]We don't have as many statistics as usual.

0:35:54.579,0:36:00.570
But we have some great stories too. We'll[br]hurry up. So this year in total, we

0:36:00.570,0:36:07.790
covered 10 stages apart from the 5 stages[br]that we do usually for Congress. We had

0:36:07.790,0:36:11.950
streams from the critical decentralisation[br]cluster, Sendezentrum, Wikipaka WG, Open

0:36:11.950,0:36:20.020
Infrastructure Orbit, Chaos West. And in[br]total, we served 255 hours and 35 minutes

0:36:20.020,0:36:26.640
of total talk time. So you know what to do[br]until the next Congress.

0:36:26.640,0:36:33.500
*applause*[br][Filler, please remove me in amara]

0:36:33.500,0:36:40.730
VOC1: And of course, sustainability was a[br]big topic during this Congress. So part of

0:36:40.730,0:36:48.720
what we have to do is stream reencoding so[br]you can watch it with the VP5 codec or use

0:36:48.720,0:36:57.950
it at lower resolution. And so far we've[br]been using 4 Xeon-based machines and 2

0:36:57.950,0:37:04.540
desktop machines. And thanks to hardware-[br]based encoding, we now replace this with a

0:37:04.540,0:37:13.130
single laptop. As you can maybe read, this[br]is critical infrastructure now. And for

0:37:13.130,0:37:18.510
all the streams, for 30 reencoding[br]streams, we are on a 45 watt power budget

0:37:18.510,0:37:32.260
now. And as an added benefit, because we[br]also encode the master slides with

0:37:32.260,0:37:36.990
hardware encoders, and hardware encoders[br]can generally use a higher profile that

0:37:36.990,0:37:45.360
allows for better quality in real time,[br]you now get a better picture as well. So,

0:37:45.360,0:37:50.990
yeah.[br][Filler, please remove me in amara]

0:37:50.990,0:37:56.790
*applause*[br][Filler, please remove me in amara]

0:37:56.790,0:38:04.579
VOC1: And of course, we had some minor[br]fuckups this year. We thought the audio

0:38:04.579,0:38:11.030
setup was a bit less complex. But when we[br]checked rooms, we had buzzing everywhere.

0:38:11.030,0:38:17.950
So we replaced some SDI lines with fiber[br]and turns out buzzing goes away. Then the

0:38:17.950,0:38:26.040
PA sound console had a buggy DANTE card.[br]After you reboot them, the auxiliary out

0:38:26.040,0:38:34.079
to the VOC cameras was muted. So that[br]messed up the particular talk that has

0:38:34.079,0:38:40.830
been redone today, but other than that, we[br]are rather happy. And we figured that 3 of

0:38:40.830,0:38:47.470
our audio mixers actually had broken[br]outputs. I don't know how we did that, but

0:38:47.470,0:38:51.980
it clearly shows that they've been used on[br]one event or another during the last

0:38:51.980,0:39:01.310
years, which is actually a good thing we[br]may think. On the Wikipaka stage, we did

0:39:01.310,0:39:05.570
not use Ansible because there was sort of[br]a playground for us. But if you don't do

0:39:05.570,0:39:14.390
things properly, well, then you run into[br]edge cases with things. And yeah. So I

0:39:14.390,0:39:22.410
need to hurry up. And one virtualization[br]host suddenly started leaking memory. And

0:39:22.410,0:39:26.463
so if you were affected by that during the[br]main talk season in the evening, we are

0:39:26.463,0:39:31.350
very sorry about that. Updating the kernel[br]helped and we have no idea what happened.

0:39:31.350,0:39:40.930
Yeah, and Icecast got stuck as well. And[br]some relive... so if you want to see talks

0:39:40.930,0:39:48.970
later, that may not be possible because we[br]ran temporarily out of space. But if you

0:39:48.970,0:39:54.230
watch this on media.ccc.de, and the talks[br]were not yet released, we have relive

0:39:54.230,0:39:57.990
integration, so the talks show up in[br]media.ccc.de even though there is no

0:39:57.990,0:40:03.880
proper release yet, for your convenience.[br]And main track and assemblies are now

0:40:03.880,0:40:08.820
integrated in all events, so you don't[br]have to click through 4 separate events to

0:40:08.820,0:40:15.609
find your favorite talk. And now I pass to[br]Pat to talk about VOCTOMIX 2.

0:40:15.609,0:40:23.690
Pat: Yeah. Thank you. Okay. I have now 20[br]seconds, I think. I made a redesign of

0:40:23.690,0:40:31.220
VOCTOMIX, it's now called VOC2MIX. And[br]Peter was doing that meme some weeks ago,

0:40:31.220,0:40:37.589
because we had to switch to VOCTOMIX 2 and[br]we wanted to try it in 2 rooms. And in the

0:40:37.589,0:40:45.060
night from day 0 to 1 we decided to do it[br]for every stage because the old solution

0:40:45.060,0:40:55.640
was not working anymore. That was a little[br]bit hot, but it worked. And, the redesign

0:40:55.640,0:41:01.790
caused the new UI, complete with some new[br]base features. We have now transitions

0:41:01.790,0:41:10.390
where pictures are moving, and we have[br]insertions for blending text into the

0:41:10.390,0:41:16.780
picture and we have a new audio mixing and[br]we are now proper A/V Sync in every case,

0:41:16.780,0:41:19.760
I think.[br][Filler, please remove me in amara]

0:41:19.760,0:41:22.740
*applause*[br][Filler, please remove me in amara]

0:41:22.740,0:41:29.109
Pat: And some mixer angels were exploring[br]the software and they found some bonus

0:41:29.109,0:41:36.310
features like random video distortion in[br]some cases, which I have to fix, I think.

0:41:36.310,0:41:40.660
And the party mode where you click some[br]buttons and they are clicking without any

0:41:40.660,0:41:46.849
doing of the user and everything is[br]flickering and they called it party mode.

0:41:46.849,0:41:51.730
This is what the current pipeline looks[br]like. We have now over 200 gstreamer

0:41:51.730,0:41:56.480
elements doing all this stuff to get your[br]pictures, which you are having on the

0:41:56.480,0:42:03.480
stream and in the recordings. That's it.[br]VOC1: So, of course, there were some

0:42:03.480,0:42:06.230
issues. I mean VOCTOMIX2 is essentially a[br]rewrite.

0:42:06.230,0:42:11.930
H: You have to speed up a bit. Actually we[br]are stealing time from the other teams. I

0:42:11.930,0:42:17.810
might call it a quit.[br]VOC1: OK OK OK. So...

0:42:17.810,0:42:21.560
H: Pressure![br]VOC1: Yes, I know. But you're not making

0:42:21.560,0:42:32.280
things better. So one thing to mention: we[br]had to deploy a sweaty finger fix after

0:42:32.280,0:42:39.869
the first talk started. Ok, here are your[br]stats, read them now,  read them read them

0:42:39.869,0:42:44.099
read them![br][Filler, please remove me in amara]

*applause*[br][Filler, please remove me in amara]

0:42:45.165,0:42:55.800
H: Please give VOC a hand. Thank you. So[br]what's next? Oh, the Stage manager and

0:42:55.800,0:43:02.920
Herald Operation Center. I'm part of it.[br]And we have 36 heralds, every one of them

0:43:02.920,0:43:07.690
very eloquent and good-looking. Then we[br]have 70 stage managers and stage

0:43:07.690,0:43:15.780
supporters. We had 150 shows on official[br]stages and the assemblies on top of it. We

0:43:15.780,0:43:20.470
have one stage fright council yet for the[br]speakers who took care of at least six

0:43:20.470,0:43:29.070
talks. And then we threw away over 100[br]hosting cards on day 1 only. So clearly,

0:43:29.070,0:43:35.690
give a hand for the SHOC.[br][Filler, please remove me in amara]

0:43:41.180,0:43:45.180
H: So next, c3power. Your time.[br]Arif: So my name is Arif Guy. I am from

0:43:45.180,0:43:49.770
the power team and from the radio[br]operation center. We make the power. We

0:43:49.770,0:43:55.900
load five double trucks of shit out on[br]Sunday 15th. We deploy a lot of power

0:43:55.900,0:44:02.950
boxes and many cables. So we have teardown[br]today so every help is needed. We have

0:44:02.950,0:44:09.410
only one day to bring us back. The main[br]thing, we had the power meter that we made

0:44:09.410,0:44:18.190
on the camp this year. We have two nice[br]setup on room H. You see the power factor

0:44:18.190,0:44:25.560
is very bad. And the other one was the[br]Waffle Operation Center so you see they

0:44:25.560,0:44:31.730
have a nice power factor. So please use[br]more ohmic devices like heaters, waffle

0:44:31.730,0:44:42.960
iron or something. We only have 5 Seaview[br]to monitor Yolocolo. You have on

0:44:42.960,0:44:48.849
c3power.top a Grafana link that also links[br]to the main Grafana to the NOC. Another

0:44:48.849,0:44:57.520
nice thing we have on the lounge, I have a[br]video here. It started now. You can see

0:44:57.520,0:45:06.349
the current on all 3 phases to the audio[br]and you can see the audio from the lounge.

Arif: Use more bass, or make more current.[br]Later we can show you another slide. Go to

0:45:44.670,0:45:56.420
next slide please. So for the radio team[br]we have 120 portable radios. We have

0:45:56.420,0:46:01.670
updated them to a new firmware, and a new[br]programming software with a new feature

0:46:01.670,0:46:07.440
that is a lot slower than the last[br]version. Very nice. 50 bring-your-own-

0:46:07.440,0:46:13.160
device radios. 5 dead radios from the[br]camp. 2 dead from 36c3. 2 dead repeaters

0:46:13.160,0:46:18.410
from the camp. 1 dead on arrival on this[br]stage. 3 rental repeaters from 2

0:46:18.410,0:46:24.460
companies, one we picked up in Hannover[br]just before the Congress, and even the

0:46:24.460,0:46:30.470
windows PC crashed down dead on arrival.[br]Business as usual. So, next team!

0:46:30.470,0:46:42.760
H: Thank you! So, the next is c3subtitles.[br]I think it's Amy and Julia. Amy. They are

0:46:42.760,0:46:51.760
not. C3SOS. S.O.S. It's you. Okay. Okay.[br]Sorry. Oh, I'm sorry. Not the subtitles.

0:46:51.760,0:46:55.370
It's well, sustainability. Your stage, go[br]for it. Here, feel free.

0:46:55.370,0:47:03.819
Amy: Hello. Okay, hi. My name is Amy, I'm[br]part of the c3sustainability team. I only

0:47:03.819,0:47:08.880
have four slides, so I'll be very quick.[br]You can see, the first of our biggest

0:47:08.880,0:47:13.650
projects was the drinking water[br]dispensers. So for angels, we had drinking

0:47:13.650,0:47:17.880
water from a dispenser rather than from[br]bottles and they could refill their

0:47:17.880,0:47:22.060
bottles. We go through some stats there.[br]So when we started planning how difficult

0:47:22.060,0:47:27.250
it was to implement it, the locations, and[br]how many volunteers, satisfaction was very

0:47:27.250,0:47:32.250
high for this one. So thank you to c3geld[br]who really helped organize the water

0:47:32.250,0:47:36.830
dispensers with us. We're very happy. They[br]were really great. Please give them a

0:47:36.830,0:47:38.830
round of applause.[br][Filler, please remove me in amara]

*applause*[br][Filler, please remove me in amara]

0:47:39.910,0:47:43.800
Amy: Thank you. The next one was a give[br]and take electronic box. So we wanted to

0:47:43.800,0:47:47.530
encourage people not to throw away their[br]electronics. Of course, they can be

0:47:47.530,0:47:52.859
recycled. So we have deployed 10 boxes.[br]You can find them in the sticker stations.

0:47:52.859,0:47:58.440
And we did this in collaboration with the[br]hardware hacking area. Thank you. And

0:47:58.440,0:48:00.440
other assemblies. Oh, wow, you are really[br]fast.

0:48:00.440,0:48:02.440
H: Yes I am.[br]Amy: Okay!

0:48:02.440,0:48:05.960
H: Others are waiting![br]Amy: Okay. So the last one I wanted to go

0:48:05.960,0:48:10.780
through. We have two initiatives on this[br]one. I'm sorry for the trashy picture

0:48:10.780,0:48:17.240
there. We have organic bins in the halls.[br]It was very, very difficult to do this.

0:48:17.240,0:48:21.339
But actually it was quite satisfactory.[br]But I would say there is room for

0:48:21.339,0:48:26.930
improvement there. And there was also an[br]initiative for recycling cigaret butts. So

0:48:26.930,0:48:29.480
we actually had two people go round,[br]collect your cigaret butts and they will

0:48:29.480,0:48:37.460
be recycled into cool ashtrays. What a[br]success! Thank you so much to everyone who

0:48:37.460,0:48:40.750
collaborated with us. We couldn't do out[br]without your help.

0:48:40.750,0:48:44.100
H: Thank you. Your applause, please.[br][Filler, please remove me in amara]

0:48:44.100,0:48:46.670
*applause*[br][Filler, please remove me in amara]

0:48:46.670,0:48:51.089
H: So unfortunately, the c3sign is not[br]coming. So just take a look at those

0:48:51.089,0:48:57.400
pictures while I go through them. And now[br]the next one is C3 Assemblies. Here, take

0:48:57.400,0:49:03.960
this one. Thank you. Be quick.[br]Pingu: Hi, my name is Pingu. I'm here for

0:49:03.960,0:49:11.460
the assembly team. And I just want to ask,[br]give a hand who hasn't found his assembly

0:49:11.460,0:49:19.020
on day zero or day one? So then give a big[br]applause to c3nav because they really

0:49:19.020,0:49:28.690
helped us a lot. Because without them, it[br]wasn't able to do this event just for us.

0:49:28.690,0:49:37.329
Because for some figures we had 419[br]assemblies to place on this area which is

0:49:37.329,0:49:45.060
about 35000 square meters. We had 3000[br]tables all over, 2500 in the assemblies,

0:49:45.060,0:49:53.820
with 6000 chairs. And here, please give a[br]big applause to the C3Möbelhaus or IKEA as

0:49:53.820,0:49:57.359
you call it.[br][Filler, please remove me in amara]

0:49:57.359,0:50:00.520
*applause*[br][Filler, please remove me in amara]

0:50:00.520,0:50:07.930
Pingu: Because the Möbelhaus basically[br]placed all the tables in a magic night on

0:50:07.930,0:50:16.990
basically day -2. And they will disappear[br]with the help of C3Möbelhaus today. We

0:50:16.990,0:50:25.450
assigned the last assembly on day zero at[br]22:00 and we started our work in mid-

0:50:25.450,0:50:33.460
October with weekly meetings. And yeah, as[br]you can see, it was a lot of work and...

0:50:33.460,0:50:36.119
Oh.[br]H: Thank you.

0:50:36.119,0:50:44.950
Pingu: Thank you. And just one thing, for[br]teardown, for tearing down the assemblies,

0:50:44.950,0:50:54.010
please stack the chairs on the assembly[br]but leave every chair and every table on

0:50:54.010,0:51:13.900
the assembly, we will get rid of them.[br]H: Thanks a lot. Your applause. So the

0:51:13.900,0:51:20.569
next ones are... Les prochains, ce sont[br]les gens de c3lingo, voilà, vos tours!

0:51:20.569,0:51:26.161
c3lingo 1: Hallo! Schön euch mal (...) Wir[br]sind übersetzet. (...)

0:51:26.161,0:51:32.190
German>[br]Oh, sorry. Well, I'm also fine with that.

0:51:32.190,0:51:35.540
We translated all the German talks into[br]English. All the English talks into

0:51:35.540,0:51:40.170
German. All in all, fifteen thousand[br]minutes in seven different target

0:51:40.170,0:51:45.089
languages. And here is from the second[br]language team, who talk all the non-

0:51:45.089,0:51:49.480
English and non-German things.[br]c3lingo 2: Okay. So basically we did have

0:51:49.480,0:51:57.450
about 1/3 of the talks were translated to[br]French. Yeah. You can read the rest. And

0:51:57.450,0:52:00.900
we even have currently, exactly, right[br]now, another one which is translated into

0:52:00.900,0:52:05.060
Swabian. So if you want to listen into it.[br][Filler, please remove me in amara]

0:52:05.060,0:52:07.030
*applause*[br][Filler, please remove me in amara]

0:52:07.030,0:52:11.491
c3lingo 2: Which means that if you were[br]listening to a talk, there is 2 chance out

0:52:11.491,0:52:17.710
of 3 that it was translated not only once,[br]but twice. Into either French, Spanish,

0:52:17.710,0:52:21.900
Russian, or Polish. One special mention[br]for the Russian and Polish teams, that was

0:52:21.900,0:52:25.010
their first time this year. So one big[br]round of applause for them, please.

0:52:25.010,0:52:29.790
*applause*[br][Filler, please remove me in amara]

0:52:29.790,0:52:36.760
c3lingo 2: And one more big thank about[br]for the guys who brought the cough candies

0:52:36.760,0:52:41.380
and cough drops in the booth. That's a[br]lifesaver. Thanks.

0:52:41.380,0:52:48.559
H: Thank you. Merci beaucoup. So we have[br]some heart operation going on here. You

0:52:48.559,0:52:50.790
have to switch it or not? Oh, you're good[br]with computers.

0:52:50.790,0:52:54.790
*laughing*[br][Filler, please remove me in amara]

0:52:54.790,0:53:00.829
H: He just *mimicks something*. So[br]c3infrastructure from the subtitles. Your

0:53:00.829,0:53:09.430
stage. Yeah. My microphone. Ha ha.[br]td: So, thanks. Just a quick look into the

0:53:09.430,0:53:13.980
subtitles. So what do we actually do when[br]we subtitle a talk? Well, first of all, we

0:53:13.980,0:53:18.600
take the video from the C3VOC and put it[br]through speech recognition just to get a

0:53:18.600,0:53:24.290
rough transcript that we can then give to[br]angels to actually correct, because, well,

0:53:24.290,0:53:29.569
machine speech recognition doesn't work so[br]good at all. And then once we have a

0:53:29.569,0:53:34.390
working transcript that humans have looked[br]at, we put that through auto-timing, which

0:53:34.390,0:53:38.220
just takes the transcript and aligns that[br]with the audio, and that usually works

0:53:38.220,0:53:43.010
pretty well. And, well, once that is[br]finished, then we actually have working

0:53:43.010,0:53:47.299
subtitles, but we give them to angels for[br]another round of review just to fix any

0:53:47.299,0:53:51.980
mistakes that got overlooked. And maybe[br]sometimes the timing needs to be adjusted.

0:53:51.980,0:53:55.720
And then, when that is done, well, the[br]subtitle is released. And actually one of

0:53:55.720,0:54:01.010
our angels did a nice chart about all this[br]process that you can see here. It all

0:54:01.010,0:54:09.800
sounds better, so thank you for that.[br]Well, no presentation without graphs. As

0:54:09.800,0:54:12.420
you can see, the important thing is[br]really: everything goes up and to the

0:54:12.420,0:54:19.440
right. On the bottom here we have finished[br]seconds of transcribed talks. So this is

0:54:19.440,0:54:22.300
really completed subtitles here. And it[br]starts already quite high because it

0:54:22.300,0:54:28.470
includes all the Congresses before. Then[br]we have stuff that has been reviewed in

0:54:28.470,0:54:34.790
orange. Stuff that has been timed but not[br]reviewed yet in yellow. And transcribed

0:54:34.790,0:54:44.609
but not yet timed stuff in green. All in[br]all, we had 144 distinct angels. Yeah, I

0:54:44.609,0:54:53.140
need to hurry up. 71% of which took 2[br]shifts and 10% took 7 or more shifts. So

0:54:53.140,0:54:58.500
433 hours of work for 126 hours of[br]material. And so far we've had 6 releases

0:54:58.500,0:55:02.859
from this Congress and then lots of hours[br]worked. All of these numbers are at least

0:55:02.859,0:55:07.380
as high as last year's numbers, so good,[br]thanks. When you have transcripts, you can

0:55:07.380,0:55:11.200
do cool stuff with that. So, for example,[br]generate word clouds to see what people

0:55:11.200,0:55:15.190
like. And this case, people seem to like[br]people and questions and time, which we

0:55:15.190,0:55:20.610
don't have any here. So. Well, how do we[br]actually keep track of all this

0:55:20.610,0:55:26.070
complicated stuff? Well, we use a state-[br]of-the-art NoSQL lock-free columnar data

0:55:26.070,0:55:32.390
store, like many of the other teams also[br]do. And well, thank you all of our angels

0:55:32.390,0:55:38.070
for your hard work. And also thanks for[br]the Heaven for supporting us. And then,

0:55:38.070,0:55:41.440
well, if you if you feel bored between[br]Congresses, you can still continue to work

0:55:41.440,0:55:44.200
on transcripts. You have all the[br]informations here, these slides will be

0:55:44.200,0:55:47.219
online, follow us on Twitter. And thank[br]you.

0:55:47.219,0:55:49.450
*applause*[br][Filler, please remove me in amara]

0:55:49.450,0:55:54.420
H: Please do your thing again, like your[br] thing again, like do *mimicks

0:55:54.420,0:55:57.630
something*. Take your laptop.[br][Filler, please remove me in amara]

0:55:57.630,0:55:59.869
*laughing*[br][Filler, please remove me in amara]

0:55:59.869,0:56:04.400
H: So this was the last one. I think I[br]will try my best to do something like this

0:56:04.400,0:56:09.010
too. Actually I'm not good with computers,[br]but I know someone who is and who takes

0:56:09.010,0:56:15.070
very great care of everyone of us. So one[br]of my highlights of every Congress, feel

0:56:15.070,0:56:25.079
free, the LOC![br]LOC: Hello. I'm the stand-in for LOC. As

0:56:25.079,0:56:30.450
with all good projects, they're too busy[br]for documentation. They're packing. So LOC

0:56:30.450,0:56:36.270
doesn't have anything. I'm more of the[br]Department of Health and Safety again. So

0:56:36.270,0:56:40.900
for everyone: we have the message from[br]CERT that there were no work-related

0:56:40.900,0:56:47.660
accidents that caused real harm. The odd[br]broken Mate bottle maybe. But thank you

0:56:47.660,0:56:56.849
for having built a city again safely and[br]orderly, even with all the chaos. For the

0:56:56.849,0:57:01.069
people who are driving, please make sure[br]that the drugs wear off and that you get

0:57:01.069,0:57:08.220
some sleep and for all people riding[br]along, please keep the guys awake. That

0:57:08.220,0:57:11.710
would be greatly appreciated. Go home[br]safely. Thank you very much.

0:57:11.710,0:57:15.960
*applause*[br][Filler, please remove me in amara]

0:57:15.960,0:57:25.660
H: So. Wow, ah, OK. So I'm very sorry to[br]have to rush some teams and I'm very sorry

0:57:25.660,0:57:29.160
that we don't have any time left. We are 1[br]minute over and I promised the teardown

0:57:29.160,0:57:36.530
crew to not do overtime. So please, please[br]give all the teams their respect and clap

0:57:36.530,0:57:40.240
and tramp as loud as you can for now to[br]finish!

0:57:40.240,0:57:43.280
*standing ovation*[br][Filler, please remove me in amara]

0:57:43.280,0:57:50.280
H: Everything! They did! For us! We did![br]For them! Why are you still sitting? You

0:57:50.280,0:57:54.280
have to leave. Thank you. From the[br]c3infrastructure Review. Goodbye.
