00:00:19,350 --> 00:00:23,510
Herald: Hello and welcome to
Infrastructure Review. This review is
2
00:00:23,510 --> 00:00:28,080
being translated into a lot of languages
and we don't know yet which one, but the
3
00:00:28,080 --> 00:00:35,020
c3lingo team will be on stage and will
tell us how and what it did. I'd like to
4
00:00:35,020 --> 00:00:42,340
start, as always and every year, with the
NOC, right. So please give the NOC a hand.
5
00:00:42,340 --> 00:00:48,130
applause
[Filler, please remove me in amara]
6
00:00:48,130 --> 00:00:54,810
Momo: All right, everyone, welcome to the
State of the Internet manufacture report.
7
00:00:54,810 --> 00:00:58,850
This is JC, I'm Momo and we're going to
talk to you about what we did this year
8
00:00:58,850 --> 00:01:05,730
for the network. So obviously, organizing
Congress is a quite tedious task. Took us
9
00:01:05,730 --> 00:01:10,110
about six months of pre-planning. We came
in on the 15th, did a fiber day and then
10
00:01:10,110 --> 00:01:14,500
it took us from the 18th and will take us
till tomorrow to tear everything down with
11
00:01:14,500 --> 00:01:18,400
like 20 to 40 people. And we'll be busy
wiping every device because that is
12
00:01:18,400 --> 00:01:21,470
actually what we do every year. We delete
everything. There are no logs leaving this
13
00:01:21,470 --> 00:01:27,540
building and this will take us probably
the next 24 hours. So yeah, for the usual
14
00:01:27,540 --> 00:01:31,610
numbers. Edge capacity: this year because
you didn't use all the Internet last year,
15
00:01:31,610 --> 00:01:36,520
we only brought you 300 gigs, but that was
fine as well, I suppose. We got 100 gig
16
00:01:36,520 --> 00:01:40,620
from HLKomm here in Leipzig, 100 gig from
Deutsche Telekom and as well as 100 gig
17
00:01:40,620 --> 00:01:48,479
from BCIX which we got via DWDM wave to
Berlin. In the core we used Juniper
18
00:01:48,479 --> 00:01:56,549
MX960s, MX480s, MX204s and QFX10002 in the
yolocolo. Basically all the halls were
19
00:01:56,549 --> 00:02:02,280
connected via a 200 gig link and yolocolo
had three times 100 gig. As probably the
20
00:02:02,280 --> 00:02:09,330
last five or so years, we're using IS-IS
and BGP for our protocols of choice. And
21
00:02:09,330 --> 00:02:13,860
this year we also first off rejected RPKI
invalid routes and secondly applied for
22
00:02:13,860 --> 00:02:19,890
the first time at congress BCP38 ingress
filtering to be a good internet citizen
23
00:02:19,890 --> 00:02:26,830
and not to allow you to spoof IP
addresses. So yeah, that was nice. As
24
00:02:26,830 --> 00:02:31,330
Congress keeps on growing, we have 2500
tables somewhere around the building in
25
00:02:31,330 --> 00:02:35,459
all the assemblies, but we only have 300
switches. So sorry if you had to bring a
26
00:02:35,459 --> 00:02:40,401
long cable and if you have switches to
spare with 10 gig uplinks and POE+, feel
27
00:02:40,401 --> 00:02:47,530
free to donate them to us. Access and Wi-
Fi. We had like 300 access switches. We
28
00:02:47,530 --> 00:02:51,330
are obviously again running Aruba Wi-Fi
controllers. This year, like at camp we
29
00:02:51,330 --> 00:02:57,630
had a few 802.1x access points, more on
that later. We tried to use Juniper vMX to
30
00:02:57,630 --> 00:03:03,000
route the Wi-Fi traffic. And had quite a
shitload of switches, most of them from
31
00:03:03,000 --> 00:03:08,849
Juniper, some Cisco 2960s, some Brocades
which are new to us, and some crappy old
32
00:03:08,849 --> 00:03:13,470
HPE stuff which is basically configured
for us to work like a brick you get from
33
00:03:13,470 --> 00:03:18,610
like eBay or whatnot. We had a few
incidents this year we'd like to talk
34
00:03:18,610 --> 00:03:23,150
about. First off, we had, I'm not sure if
any of you noticed, quite a lot of packet
35
00:03:23,150 --> 00:03:28,560
loss and missing router advertisements on
the Wi-Fi. This was caused by some weird
36
00:03:28,560 --> 00:03:32,780
Juniper vMX behavior. We couldn't figure
out what it was. So we had them running in
37
00:03:32,780 --> 00:03:38,739
a redundant VRRP setup. We shut down one
of them and then it worked. So yeah, fuck
38
00:03:38,739 --> 00:03:45,239
redundancy. There was a pixelflut client
which somehow messed up his IP address and
39
00:03:45,239 --> 00:03:52,650
caused a broadcast storm which took down
most parts of Hall 2. We found them, shut
40
00:03:52,650 --> 00:03:59,671
it down and deployed storm control to all
our access switches. Yeah, to the Congress
41
00:03:59,671 --> 00:04:06,120
motto resource exhaustion: someone was
running aggressive zmap scanning over the
42
00:04:06,120 --> 00:04:10,989
whole internet, came by our Wi-Fi access
controller and caused a state table
43
00:04:10,989 --> 00:04:15,620
exhaustion. And that brought it down. We
null-routed the source and yeah, there was
44
00:04:15,620 --> 00:04:23,990
this issue. So thank you to whoever was
that. And in the morning of day 3, we had
45
00:04:23,990 --> 00:04:27,890
another issue with Juniper vMX where it
forgot it had a network card. We rebooted
46
00:04:27,890 --> 00:04:33,139
it and everything was fine again. So yeah,
some numbers. You actually managed to use
47
00:04:33,139 --> 00:04:39,340
more bandwidth, thank you.
[Filler, please remove me in amara]
48
00:04:39,340 --> 00:04:43,380
applause
[Filler, please remove me in amara]
49
00:04:43,380 --> 00:04:47,830
M: But it's still only 20% of our uplink
capacity. So use more. 20% of that was
50
00:04:47,830 --> 00:04:53,650
IPv6, which is good, but could be more. We
had like 11000 clients into Wi-Fi. 86% 5
51
00:04:53,650 --> 00:05:02,240
GHz, 96% in a peak.
We had eleven 802.11ax clients. Our
52
00:05:02,240 --> 00:05:09,240
favorite one was obviously the one with
the lovely hostname ILOVETHENOC. So yeah,
53
00:05:09,240 --> 00:05:14,919
about that number we have, 96% 5 GHz
obviously shows us that we are finally at
54
00:05:14,919 --> 00:05:20,440
the point where we can say: thank you 2.4
GHz, it was nice. Goodbye.
55
00:05:20,440 --> 00:05:24,919
applause
[Filler, please remove me in amara]
56
00:05:24,919 --> 00:05:32,240
M: Also, obviously, thank you to our
sponsors. We couldn't do this if we would
57
00:05:32,240 --> 00:05:37,110
not get like 10 millions, of list price
obviously, of equipment and loan and quite
58
00:05:37,110 --> 00:05:40,350
a lot of services. So give them a round of
applause as well. Thank you.
59
00:05:40,350 --> 00:05:46,389
applause
[Filler, please remove me in amara]
60
00:05:46,389 --> 00:05:50,889
M: And obviously NOC not only stands for
Network Operation Center, but if you
61
00:05:50,889 --> 00:05:55,870
extend it, it is No CO2. So we believe in
green power and clean traffic and
62
00:05:55,870 --> 00:06:01,039
therefore we obviously see that
sustainability is a great part of our
63
00:06:01,039 --> 00:06:05,420
role. This is why we even use old crappy
HP switches to cut our lines for our
64
00:06:05,420 --> 00:06:07,919
tchunk to serve your cheese boards,
whatever you need.
65
00:06:07,919 --> 00:06:10,400
laughter
[Filler, please remove me in amara]
66
00:06:10,400 --> 00:06:13,240
M: Also...
[Filler, please remove me in amara]
67
00:06:13,240 --> 00:06:15,729
applause
[Filler, please remove me in amara]
68
00:06:15,729 --> 00:06:21,270
M: Also, we somehow estimated what our
network will run us in CO2 and that was
69
00:06:21,270 --> 00:06:26,229
about 11 tons. We're not very good with
mass and not very good with CO2 emissions,
70
00:06:26,229 --> 00:06:31,410
but this was roughly what we came up with.
And to make Congress or the world a bit
71
00:06:31,410 --> 00:06:40,970
better place, we actually offset all our
CO2 and bought eleven tons of CO2
72
00:06:40,970 --> 00:06:49,419
emissions. And now Frederick is gonna tell
you how we got all those numbers.
73
00:06:49,419 --> 00:06:54,849
Frederick: Yeah, as a good internet
manufacture, we also do monitoring a lot
74
00:06:54,849 --> 00:07:00,069
and we run our own Prometheus server
inside. You probably know the dashboard
75
00:07:00,069 --> 00:07:06,300
that we propagate all over the internet
and that's powered by Prometheus. We have
76
00:07:06,300 --> 00:07:12,250
an internal Grafana that is part of this
whole ecosystem. And if you are a little
77
00:07:12,250 --> 00:07:16,000
bit of a nerd, you might have clicked on
the dashboard sections and seen that there
78
00:07:16,000 --> 00:07:23,420
are more dashboards than this. We fill our
Prometheus with lots of different sources:
79
00:07:23,420 --> 00:07:30,080
we get SNMP data from, and screw SNMP, but
it does a quite good job at getting all
80
00:07:30,080 --> 00:07:34,740
the insights we need from all the network
equipment. We have node_exporter, influx
81
00:07:34,740 --> 00:07:40,650
and all that, but we got a decent amount
of data from everyone in the Congress
82
00:07:40,650 --> 00:07:45,699
ecosystem and we had that at camp as well
where we got the water pressure of the
83
00:07:45,699 --> 00:07:52,169
showers. And we get the colo power, which
also helps with estimating the CO2
84
00:07:52,169 --> 00:07:58,190
footprint. And everything is being
configured by Netbox, which is a tool that
85
00:07:58,190 --> 00:08:06,139
is an asset database. And as I said, we
have lots of dashboards and graphs. Of
86
00:08:06,139 --> 00:08:09,660
course, the public one where you can see
lots of different things from everyone.
87
00:08:09,660 --> 00:08:15,950
This is only part of it. If you scroll
down on the dashboard, you see a lot more.
88
00:08:15,950 --> 00:08:19,319
But this helps everyone to have a good
understanding of what is happening
89
00:08:19,319 --> 00:08:23,669
currently. And we even draw a nice little
Christmas trees on the Wi-Fi traffic for
90
00:08:23,669 --> 00:08:28,270
you. That is mostly because it's a router-
on-a-stick and we cannot measure it
91
00:08:28,270 --> 00:08:32,570
correctly. We have an internal dashboard
which gives us a little bit of a status
92
00:08:32,570 --> 00:08:40,120
for build-up mostly: which switches and
routers are up? And that gives us a very
93
00:08:40,120 --> 00:08:45,620
quick sight of all the devices that are
out there. What's broken? What's not
94
00:08:45,620 --> 00:08:50,070
broken? We improved it a little and now
have alarms so someone can look at stuff
95
00:08:50,070 --> 00:08:58,540
and see if things are broken, run out
there and fix it. We also built
96
00:08:58,540 --> 00:09:03,850
weathermaps. As you can see that's a
little bit of a mess. But we couldn't do
97
00:09:03,850 --> 00:09:11,459
it better because the graphing library
doesn't allow us to do it better. If
98
00:09:11,459 --> 00:09:16,029
someone has a good idea to do it better in
Grafana or anywhere else with sources from
99
00:09:16,029 --> 00:09:21,370
Prometheus, please come to us, we're happy
to talk. But this shows our core and all
100
00:09:21,370 --> 00:09:26,399
the links between it and how much capacity
is being used. Red indicates that it's
101
00:09:26,399 --> 00:09:32,980
used more heavily. We also have that for
the yolocolo. And all the traffic around
102
00:09:32,980 --> 00:09:41,149
it as well. And, yeah, teardown starts
now. Please don't touch our equipment. And
103
00:09:41,149 --> 00:09:45,709
if you want to come and help, please come
to Hall 4 and get in touch. We always need
104
00:09:45,709 --> 00:09:50,089
helping hands. But please in an organized
way don't disassemble switches or access
105
00:09:50,089 --> 00:09:56,220
points. We have lists and everything. We
need to account for everything. So please
106
00:09:56,220 --> 00:09:59,970
come to Hall 4 if you want to help. And
yes, use more bandwidth and offset more
107
00:09:59,970 --> 00:10:03,930
CO2. Thank you.
[Filler, please remove me in amara]

applause
[Filler, please remove me in amara]
109
00:10:06,029 --> 00:10:11,399
H: So thanks a lot. Actually, because
you're clearly the backbone or one of
110
00:10:11,399 --> 00:10:15,950
those many backbones of the conference, is
there any Q? Let's do a Q&A for like one
111
00:10:15,950 --> 00:10:18,769
or two questions.
Is anyone having a question right now?
112
00:10:18,769 --> 00:10:23,390
Someone is standing up. Right, microphone
number one, please.
113
00:10:23,390 --> 00:10:26,930
Q: Hey, we've absolutely don't ...
[Filler, please remove me in amara]
114
00:10:26,930 --> 00:10:28,930
H: Nearer, nearer.
[Filler, please remove me in amara]
115
00:10:28,930 --> 00:10:33,670
Q: We've absolutely done bcp38 in
previous years, by the way.
116
00:10:33,670 --> 00:10:37,730
M: Sorry for what I said then, I'm sorry.
Q: So I wanted to correct the record.
117
00:10:37,730 --> 00:10:40,920
We've been good netizens in previous years
as well.
118
00:10:40,920 --> 00:10:46,399
H: Oh, you're right. Thank you. Was there
another question or something else to
119
00:10:46,399 --> 00:10:49,020
correct them? Because they clearly don't
know what they're doing.
120
00:10:49,020 --> 00:10:50,830
laughter
[Filler, please remove me in amara]
121
00:10:50,830 --> 00:10:57,010
H: Yeah. Feel free. Microphone number two.
Q: So if 2.4GHz is over, what's going to
122
00:10:57,010 --> 00:11:02,450
happen to all of the ESP32 in various IoT
devices? Are they going to have a home
123
00:11:02,450 --> 00:11:06,260
here next year?
M: They'll definitely have a home. But as
124
00:11:06,260 --> 00:11:09,390
usual, we cannot support it as good as we
can on 5GHz because obviously this band is
125
00:11:09,390 --> 00:11:17,860
overused and not even remotely suited for
that amount of clients we put on it.
126
00:11:17,860 --> 00:11:24,820
Q: A follow-up for the ESP32. How exactly
can you locate them through the wireless
127
00:11:24,820 --> 00:11:31,150
if they are lost?
M: Well, we can't. We can basically look
128
00:11:31,150 --> 00:11:34,820
at which access point they are, and then
if someone really would want to, we could
129
00:11:34,820 --> 00:11:38,610
start triangulation, but we've never done
that before. So yeah, we can just pin them
130
00:11:38,610 --> 00:11:46,120
roughly to an access point.
H: Maybe we can ask c3nav next time. So
131
00:11:46,120 --> 00:11:49,560
please give the NOC a hand.
Thank you.

[Filler, please remove me in amara]
133
00:11:52,389 --> 00:11:59,639
H: So, the next team up is the POC. Do we
have to click this? Use more bandwidth,
134
00:11:59,639 --> 00:12:04,770
I'm going to try. Ah! Thank you. Your
stage.
135
00:12:04,770 --> 00:12:07,990
Garvin: Thanks.
[Filler, please remove me in amara]

[Filler, please remove me in amara]
138
00:12:14,060 --> 00:12:17,950
G: Hi, and I'm Garvin and we're from Phone
Operation Center and we want to talk a bit
139
00:12:17,950 --> 00:12:20,850
about the phone infrastructure at this
event.
140
00:12:20,850 --> 00:12:27,420
M: Yeah. So we arrived at day -6 and
planned on hacking some things
141
00:12:27,420 --> 00:12:34,100
and socializing and we planned a team
event, but then everything was different.
142
00:12:34,100 --> 00:12:40,079
G: Yeah. When we arrived, I went into the
NOC office and they said to me, "Ja, CCL
143
00:12:40,079 --> 00:12:44,490
is up, internet is up, everything is just
working nicely. You can start hook up your
144
00:12:44,490 --> 00:12:51,050
telephony system right now." And I was
like, whoa. So thanks a lot NOC. Really
145
00:12:51,050 --> 00:12:54,810
great performance this year, we were
amazed. Nobody expected that it works so
146
00:12:54,810 --> 00:12:57,970
well.
[Filler, please remove me in amara]
147
00:12:57,970 --> 00:13:01,140
applause
[Filler, please remove me in amara]
148
00:13:01,140 --> 00:13:06,399
M: Yeah. So we put up the first antennas
and then we decided to have our team event
149
00:13:06,399 --> 00:13:16,399
anyway. And yeah, so we did a lot of
things. So we handed out 150 orga loan
150
00:13:16,399 --> 00:13:26,621
DECTs and we deployed 51 SIP telephones.
We also deployed 67 antennas and we had a
151
00:13:26,621 --> 00:13:32,690
POC party on day three until 7:30 a.m.
G: So you can see almost everything is
152
00:13:32,690 --> 00:13:40,170
done. I guess the remaining things are not
that important. So this is the overview of
153
00:13:40,170 --> 00:13:45,459
DECT coverage at the event. Only level
zero, because otherwise I think it would
154
00:13:45,459 --> 00:13:50,839
be overcrowded to show. Just so that you
can get a rough impression on how many
155
00:13:50,839 --> 00:13:55,650
antennas we deployed in order to give you
this DECT coverage. That you can be
156
00:13:55,650 --> 00:14:00,130
reached almost everywhere in the event and
that you can see how our tooling looks
157
00:14:00,130 --> 00:14:04,460
like, where we see how good the antennas
see each other, and that we can see that
158
00:14:04,460 --> 00:14:10,279
seamless handover work so that you can
start at our desk, walk through the area,
159
00:14:10,279 --> 00:14:16,380
into the lounge and just continue talking.
And oh, there are also some antennas that
160
00:14:16,380 --> 00:14:19,930
are outside of the building. What could
that be?
161
00:14:19,930 --> 00:14:25,759
M: That is our hotel DECT. And you can see
a typical hotel DECT installation on the
162
00:14:25,759 --> 00:14:32,250
photo. And people got really confused
about it because we also had DECT coverage
163
00:14:32,250 --> 00:14:37,230
at main station.
G: Yeah. So I got a call roughly at 4:00
164
00:14:37,230 --> 00:14:39,230
p.m. in the morning.
[Filler, please remove me in amara]
165
00:14:39,230 --> 00:14:43,589
applause
[Filler, please remove me in amara]
166
00:14:43,589 --> 00:14:50,150
G: And somebody told me. Oh, my DECT rang.
Why? Now I need to turn it off at the
167
00:14:50,150 --> 00:14:57,720
night. Why did you do this?
M: Yeah. So we also had problems. We have
168
00:14:57,720 --> 00:15:04,190
a new feature since Camp where you can see
your DECT devices and can assign them to
169
00:15:04,190 --> 00:15:07,680
your number before you even arrive, and
then everything is set up and you don't
170
00:15:07,680 --> 00:15:12,450
have to call your token anymore. And
people get really confused because they
171
00:15:12,450 --> 00:15:17,920
would call their token anyway and it calls
it invalid. So we had to explain a lot of
172
00:15:17,920 --> 00:15:26,680
this unexpected simplicity to them.
G: And then we had a battery issue this
173
00:15:26,680 --> 00:15:31,870
year. We had not enough batteries and, you
know, batteries are always empty in the
174
00:15:31,870 --> 00:15:37,010
phones when it's the most important. So we
were thinking what what can we do about
175
00:15:37,010 --> 00:15:41,070
that?
M: So we build a new device. That's our
176
00:15:41,070 --> 00:15:49,640
microwave and it can also charge devices.
So, many thanks to C3Power, because they
177
00:15:49,640 --> 00:15:55,050
helped us with tooling and actually they
have expertise to put power cables on
178
00:15:55,050 --> 00:16:04,002
devices like this. Thank you very much.

applause
[Filler, please remove me in amara]
180
00:16:05,002 --> 00:16:08,810
G: In the last years we were often asked
"how expensive is your service actually?".
181
00:16:08,810 --> 00:16:13,449
So we decided that we now provide invoices
so you can see how expensive our services
182
00:16:13,449 --> 00:16:21,579
are and we send out a lot of invoices. And
we got paid some money. But as you can see
183
00:16:21,579 --> 00:16:28,329
on the invoices, most is sponsored by CCC.
M: Yeah. And people also paid with Mate
184
00:16:28,329 --> 00:16:34,560
which is really awesome.
G: Yeah. And also people have invoices on
185
00:16:34,560 --> 00:16:39,230
a fraction of a cent and they got quite
creative on how they can pay us.
186
00:16:39,230 --> 00:16:46,460

applause
[Filler, please remove me in amara]
188
00:16:51,930 --> 00:16:54,569
M: So here are some more stats. We have
7473 registered extensions.
189
00:16:54,569 --> 00:16:58,290
G: Oh, we didn't remove this. So we were
thinking on how to compare this with
190
00:16:58,290 --> 00:17:02,779
things and we were looking at villages in
Saarland and then we thought, this is a
191
00:17:02,779 --> 00:17:05,959
stupid comparison, but we didn't remove
this.
192
00:17:05,959 --> 00:17:17,199
M: So there were 5021 attached DECT phones
and 3251 concurrent DECT phones. Which is
193
00:17:17,199 --> 00:17:21,920
about more than 1000 more than last year.
G: So thanks a lot for using DECT.
194
00:17:21,920 --> 00:17:25,390
M: Yeah. We had...
[Filler, please remove me in amara]
195
00:17:25,390 --> 00:17:27,309
applause
[Filler, please remove me in amara]
196
00:17:27,309 --> 00:17:36,150
M: There were also max 120 calls in
parallel, and we had more than 300
197
00:17:36,150 --> 00:17:43,890
thousand calls in total. That's also
really, really much. We had five eating
198
00:17:43,890 --> 00:17:52,900
meetings at heaven, the angel eating
place, and there were an average of 42
199
00:17:52,900 --> 00:18:01,270
eating meeting live viewers. We had two
lectures. You can see them on media.ccc.de
200
00:18:01,270 --> 00:18:05,490
and we had 23 super fast charged phones in
our microwave.
201
00:18:05,490 --> 00:18:11,930
applause
[Filler, please remove me in amara]
202
00:18:11,930 --> 00:18:17,580
G: Like the NOC, we also had to deal a bit
with issues during the event, and actually
203
00:18:17,580 --> 00:18:24,870
there were some DDOS attack on our account
system and somebody configured over 4000
204
00:18:24,870 --> 00:18:29,130
extensions with really stupid names. And
it took us quite a while to get rid of
205
00:18:29,130 --> 00:18:33,210
them again cleanly from the system because
the synchronization turned out to be
206
00:18:33,210 --> 00:18:39,660
really slow. So you can see it took us a
while to get them removed again. So we can
207
00:18:39,660 --> 00:18:44,330
only say, you all know it's a hacker
congress, but it's kind of stupid to hack
208
00:18:44,330 --> 00:18:48,620
your own infrastructure.
[Filler, please remove me in amara]
209
00:18:48,620 --> 00:18:51,850
applause
[Filler, please remove me in amara]
210
00:18:51,850 --> 00:18:58,480
G: So as a consequence of this, we only
allow now only 50 extensions per account
211
00:18:58,480 --> 00:19:03,040
and per event. If you think you need more,
feel free to contact us if you have a
212
00:19:03,040 --> 00:19:06,530
valid use case.
[Filler, please remove me in amara]
213
00:19:06,530 --> 00:19:12,640
M: So every device has an IPEI that is
like a MAC address and we ask the
214
00:19:12,640 --> 00:19:19,090
responsible institution to give us the
manufacturer. But it's really secret. So
215
00:19:19,090 --> 00:19:23,240
they don't give it to us. So we ask you
for help. Please enter the models of your
216
00:19:23,240 --> 00:19:29,260
devices for your phones. And then we can
match to the IPEI and get some data to
217
00:19:29,260 --> 00:19:32,990
build more awesome features for you.
[Filler, please remove me in amara]
218
00:19:32,990 --> 00:19:37,391
G: This would really help us. And the only
way for us is to crowdsource it because it
219
00:19:37,391 --> 00:19:40,650
seems to be super secret. Whatever.
[Filler, please remove me in amara]
220
00:19:40,650 --> 00:19:45,570
M: You can find it in guru3 on the device
page and there's this little pen. And if
221
00:19:45,570 --> 00:19:49,350
you click on it, then you can enter the
model.
222
00:19:49,350 --> 00:19:57,610
G: Thanks upfront. And yep, that's from
us, and I guess now we have a little time
223
00:19:57,610 --> 00:20:01,500
for you to ask questions.
[Filler, please remove me in amara]
224
00:20:01,500 --> 00:20:04,909
applause
[Filler, please remove me in amara]
225
00:20:04,909 --> 00:20:13,880
H: Great. So, any questions for the POC? I
don't see... were they correct or do we
226
00:20:13,880 --> 00:20:20,240
have to...? Ah, someone is getting up. So
microphone number 1, please.
227
00:20:20,240 --> 00:20:25,150
Q: Yes, a few years ago there was a
translation service via DECT. Is the
228
00:20:25,150 --> 00:20:29,830
capacity enough to service also this
crowd?
229
00:20:29,830 --> 00:20:36,560
G: The problem is that we switched the
phone system a while ago last year at the
230
00:20:36,560 --> 00:20:43,820
Congress. And the old phone system had a
way how we can do the translation via one
231
00:20:43,820 --> 00:20:48,510
channel and the problem is that the new
system doesn't support this. Let me say
232
00:20:48,510 --> 00:20:55,120
the new system doesn't support it yet. So
have a look at our talk and then you can
233
00:20:55,120 --> 00:21:01,690
see that there is some potential.
H: I see someone at microphone number 3,
234
00:21:01,690 --> 00:21:05,140
please. This would be the last question
because we have to hurry a bit.
235
00:21:05,140 --> 00:21:10,080
Q: Can I know a little bit more about the
super charging microwave? I'm confused.
236
00:21:10,080 --> 00:21:14,330
applause
[Filler, please remove me in amara]
237
00:21:14,330 --> 00:21:20,550
M: Sure, you can come to our POC desk and
then we answer all your questions.
238
00:21:20,550 --> 00:21:28,780
H: Ooh... mystery. Please, give the POC a
hand.
239
00:21:28,780 --> 00:21:39,940
So next team, is it from the GSM crew?
Someone there? I think we have two. I see
240
00:21:39,940 --> 00:21:44,919
some Chaos Post, you have to wait one
round. So, GSM guy thank you. I am good
241
00:21:44,919 --> 00:21:53,500
with computers, I think. Yeah, I am. Have
fun. If it's working or not. Look at this
242
00:21:53,500 --> 00:22:03,679
smile then looks better. Try this. Yeah.
Right. Try this.
243
00:22:03,679 --> 00:22:09,849
- 423.
- Maybe you have to use GSM.
244
00:22:09,849 --> 00:22:13,599
- 23 test.
- What happened?
245
00:22:13,599 --> 00:22:16,599
- Hello. Hello.
- Aah.
246
00:22:16,599 --> 00:22:24,630
GSM Person 1: So as every year we ran our
own mobile phone network at the Congress
247
00:22:24,630 --> 00:22:32,620
using osmocom open source software for 2G
and 3G, and open5gs interfacing with the
248
00:22:32,620 --> 00:22:37,909
osmocom HLR. And all you need to take part
is a SIM card that you can buy from the
249
00:22:37,909 --> 00:22:47,250
POC and for 5 euros you get a flat rate.
The price increases because we have less
250
00:22:47,250 --> 00:22:53,150
SIM cards every year. We need to
manufacture new ones. You can even call
251
00:22:53,150 --> 00:23:02,830
outside like you can with DECT phones.
Lynxis: Hello. I'm Lynxis. So as every
252
00:23:02,830 --> 00:23:09,450
year for the GSM team, the first problem
is the license. That's the first step
253
00:23:09,450 --> 00:23:16,539
usually. Because in Germany, you have to
get the official form, get a license but
254
00:23:16,539 --> 00:23:22,510
... Where do you get it? What can you ask
for frequencies? Because, for example, the
255
00:23:22,510 --> 00:23:28,940
POC for DECT or Wi-Fi, you just place it
and you can use it. You're fine.
256
00:23:28,940 --> 00:23:35,480
But for GSM, they didn't think about it or
for 3G or 4G. So yeah, this year we
257
00:23:35,480 --> 00:23:41,520
usually get the license middle of
december, maybe start of december. So it's
258
00:23:41,520 --> 00:23:51,380
already late. So this year we didn't get
all our licenses. But we get some. We got
259
00:23:51,380 --> 00:23:59,409
850 MHz, which is not assigned in Europe
because it's usually in the US only. But
260
00:23:59,409 --> 00:24:06,760
we have a small hole. This year we got a
4G license instead of a 2G license with 10
261
00:24:06,760 --> 00:24:11,640
Mhz from Telefonica. So thanks Telefonica
for borrowing us spectrum.
262
00:24:11,640 --> 00:24:18,780
applause
[Filler, please remove me in amara]
263
00:24:18,780 --> 00:24:24,080
L: Just a short example of how the
spectrum looks like. The yellow stuff is
264
00:24:24,080 --> 00:24:31,830
usually somewhere behind actually. By the
way, this microphone, it might share the
265
00:24:31,830 --> 00:24:36,450
same frequency with us. But so far, we
haven't found any interference together
266
00:24:36,450 --> 00:24:45,770
with the VOC. Down there you can see the
small hole which we are using. Because we
267
00:24:45,770 --> 00:24:51,850
didn't get the 2G license there, we
thought, OK. Let's take a look. Can we fit
268
00:24:51,850 --> 00:24:56,919
them both in the same frequencies? It's
not good. But you see the spikes, this
269
00:24:56,919 --> 00:25:03,880
nice antenna on the right. That's the GSM,
which is sending on the same frequency. It
270
00:25:03,880 --> 00:25:07,250
works because they are using different
codings. But I have heard from people who
271
00:25:07,250 --> 00:25:10,039
know more about it, this is not the way
you use it.
272
00:25:10,039 --> 00:25:13,289
laughing
[Filler, please remove me in amara]
273
00:25:13,289 --> 00:25:17,830
L: So we took some photos of our base
stations. This is actually the fairy dust
274
00:25:17,830 --> 00:25:23,909
from the 2G base station, so we have a
idea what we are using here. We have even
275
00:25:23,909 --> 00:25:31,200
more fairy dust in our 3G femtocells and
our 4G cells. They are looking like small
276
00:25:31,200 --> 00:25:37,600
toasters. They are taking actually 90
watts via POE, they have special POE
277
00:25:37,600 --> 00:25:44,740
adapters. So maybe we could ask if
somebody can do a similar adapter to get
278
00:25:44,740 --> 00:25:52,770
even running a toaster on the line.
So basically for the 4G setup this year,
279
00:25:52,770 --> 00:25:57,830
we weren't sure if it's stable enough or
we lose all our phones to the LTE and they
280
00:25:57,830 --> 00:26:05,960
don't like to come back to the 2G and 3G
setup where we have voice, because on LTE
281
00:26:05,960 --> 00:26:10,590
we don't have yet voice so you have to
select specifically to join the LTE
282
00:26:10,590 --> 00:26:16,919
network. That worked quite fine if you
change it. So your phone will register.
283
00:26:16,919 --> 00:26:24,299
Everything fine there.
GSM1: So the rollout this year: we had the
284
00:26:24,299 --> 00:26:30,690
voice working on day 0 which is new.
[Filler, please remove me in amara]

applause
[Filler, please remove me in amara]
286
00:26:34,710 --> 00:26:41,760
GSM1: Someone even noticed on Mastodon, I
saw it, too. We already had LTE at the CCC
287
00:26:41,760 --> 00:26:48,441
camp this year. Yeah, but unfortunately we
lost crypto password, so LTE roll out took
288
00:26:48,441 --> 00:26:59,860
a bit longer this time. Sorry. So some
numbers. In total we saw just about 1100
289
00:26:59,860 --> 00:27:06,490
people doing a location updating on our
network and 845 eventphone tokens were
290
00:27:06,490 --> 00:27:15,620
dialed on the GSM. That is 2G or 3G. And
there were roughly 200 phones actively
291
00:27:15,620 --> 00:27:21,110
subscribed on the network at all times.
And even though we basically only deployed
292
00:27:21,110 --> 00:27:29,240
3G nano stations in all the halls and only
had two 2G BTS in the glass halle, there
293
00:27:29,240 --> 00:27:35,390
were roughly more than half of all the
phones were still subscribed on 2G instead
294
00:27:35,390 --> 00:27:43,169
of 3G. We had like 18 3G stations and only
two plus one in the GSM room 2G stations.
295
00:27:43,169 --> 00:27:50,799
So that's a bit surprising. And SIM cards:
starting from the bottom, we sold about
296
00:27:50,799 --> 00:27:56,909
700 SIM cards, but only saw half of them
activated, which is curious. And luckily,
297
00:27:56,909 --> 00:28:02,320
most or some people bring old SIM cards
from previous years. And it's not so easy
298
00:28:02,320 --> 00:28:07,640
to get cards manufactured. So we are very
glad for everyone who brings old SIM cards
299
00:28:07,640 --> 00:28:14,460
from previous events. We might even
consider introducing charging phone calls
300
00:28:14,460 --> 00:28:18,890
only for SIM cards that are newly bought.
So if you want to continue calling for
301
00:28:18,890 --> 00:28:22,950
free, rather bring your old SIM cards.

GSM1: So you see the numbers, I'm not
going to go through them. And you can also
304
00:28:31,190 --> 00:28:40,130
get the ADM, the admin keys for your SIM
cards if you like to write to them.
305
00:28:40,130 --> 00:28:46,850
L: Or if you have seen the talk from
LaForge, you might want to play with the
306
00:28:46,850 --> 00:28:53,140
SIM cards, we give out all the keys you
want to have to play with it.
307
00:28:53,140 --> 00:29:02,640
GSM1: So operation was mostly smooth,
except iPhones, for unknown reasons. And
308
00:29:02,640 --> 00:29:06,401
except the data service, which might even
be related because maybe Apple is a bit
309
00:29:06,401 --> 00:29:12,150
more strict on whether data service is
working reliably. Yeah, we still had some
310
00:29:12,150 --> 00:29:18,360
problems in the SGs instance introducing
3G changing between the radio access
311
00:29:18,360 --> 00:29:25,559
technologies. It's a whole new ballgame so
there are still some bugs in there. And as
312
00:29:25,559 --> 00:29:30,480
you see, we had many more tickets than the
POC. This is actually reversed from the
313
00:29:30,480 --> 00:29:37,330
POC, the "done" is on the left. So this
whole bunch of stuff is done and there's
314
00:29:37,330 --> 00:29:45,010
some backlog and canceled and fantasy
tasks. It worked pretty nicely. Are you
315
00:29:45,010 --> 00:29:50,799
taking over? Oh, yeah, no, this is still
mine. And this year we actually had also a
316
00:29:50,799 --> 00:29:56,519
denial of service attack. The code was the
same as previous years and we never saw
317
00:29:56,519 --> 00:30:01,770
this before. But this year we got an
invalid mobile identity which managed to
318
00:30:01,770 --> 00:30:06,429
crash our mobile switching center. And
thank you very much for uncovering this
319
00:30:06,429 --> 00:30:12,669
bug and thanks to fixeria for fixing it on
day 2. Ever since the mobile switching
320
00:30:12,669 --> 00:30:19,820
center for Voice and SMS and subscription
has been running stable.

00:30:30,899 --> 00:30:38,120
L: Maybe some interference. We recovered
the old phones again. Last year we
323
00:30:38,120 --> 00:30:41,500
couldn't support them. But we managed to
implement the missing parts. Old phones
324
00:30:41,500 --> 00:30:46,360
could work if they support the
frequencies. So that's really nice. Maybe
325
00:30:46,360 --> 00:30:54,880
next time. Since camp, we also did a nice
angel helpdesk. And it was really
326
00:30:54,880 --> 00:31:00,000
impressive to see that we even had to add
more shifts in our shifts. We had so many
327
00:31:00,000 --> 00:31:06,000
motivated angels. Thanks to everybody who
helped us, it was really great.

333
00:31:32,039 --> 00:31:39,940
maybe nine. So we need to speed up a bit.
Our next team for now will be... We don't
334
00:31:39,940 --> 00:31:42,840
have working microphones.

interrupting for a few minutes only. We
341
00:32:03,820 --> 00:32:07,290
would like to deliver a few statistics as
well. So thanks of all, we had multiple
342
00:32:07,290 --> 00:32:14,070
chaos deliverers working throughout the
whole Congress 24/7 basically, delivering
343
00:32:14,070 --> 00:32:18,710
at the speed of chaos, as our mission
statement clearly states. So thank you
344
00:32:18,710 --> 00:32:21,549
therefore, first of all thank you very
much to all of you who contributed to
345
00:32:21,549 --> 00:32:24,149
that.

Chaos post 2: So let's have some numbers,
because you all love numbers, right? So we
348
00:32:31,770 --> 00:32:38,049
delivered about 3000 external postcards.
So that means with like outside chaos, so
349
00:32:38,049 --> 00:32:44,280
to the real world or the default world, as
we call it. We delivered those to over 42
350
00:32:44,280 --> 00:32:49,250
countries all over the world. So you guys
are really good connected internationally.
351
00:32:49,250 --> 00:32:57,549
And also, we don't have exact numbers, but
we estimate around 3500, no, 35000,
352
00:32:57,549 --> 00:33:07,909
internal postcards. And you also use our
online office for a total of 789 times. So
353
00:33:07,909 --> 00:33:12,630
that is only 15 less than camp, and that
was a longer event. So, hey, you guys
354
00:33:12,630 --> 00:33:16,200
write a lot of postcards!

Chaos post 1: As you might already know
from camp, we also do have a few special
357
00:33:23,730 --> 00:33:29,360
services. As already on camp, we had the
serving proposal, basically a pre-
358
00:33:29,360 --> 00:33:34,490
assembled text, you just had to cross what
you want. The postbox certification and of
359
00:33:34,490 --> 00:33:38,620
course, the bi-directional chaos, in
Germany also known as "Einschreiben mit
360
00:33:38,620 --> 00:33:40,620
Rückschein".
H: Wow.
361
00:33:40,620 --> 00:33:45,870
Chaos post 2: And this time we also
offered some new services. We had like
362
00:33:45,870 --> 00:33:51,149
sang telegrams, gesunges Telegram in
Deutsch. We had a forever alone box for
363
00:33:51,149 --> 00:33:56,809
people wanting to write postcards with or
exchange postcards with no idea who to
364
00:33:56,809 --> 00:34:02,100
write it to. We had love letters, so we
had some nice pre-assembled texts and also
365
00:34:02,100 --> 00:34:07,760
a really nice selection of perfumes for
scented postcards. You could write some
366
00:34:07,760 --> 00:34:12,919
secret messages. We had some UV pens and
also we had some, let's say call it
367
00:34:12,919 --> 00:34:17,679
security, or rather temper evidence,
because we had some scratch off stickers
368
00:34:17,679 --> 00:34:23,570
for you. And also we had over 30 new
postcard designs that you could use for
369
00:34:23,570 --> 00:34:25,570
postcards.

Chaos post 1: Short remark for the love
letters and the perfumes. Well, that was
372
00:34:30,679 --> 00:34:39,329
kind of not really thought through. It was
a bit... it was fun sorting them out, and
373
00:34:39,329 --> 00:34:42,950
stamping all of that, smelling all the
perfume all the time.
374
00:34:42,950 --> 00:34:46,419
Chaos post 2: And then brushing your hands
really thoroughly because, well, that
375
00:34:46,419 --> 00:34:51,899
stuff gets on your hands when you do that.
Chaos post 1: Also for UV pens. Just a
376
00:34:51,899 --> 00:34:55,280
little remark. It's not a good idea to use
it for addressing and the message.

right, then let me close up. We also
379
00:35:04,099 --> 00:35:08,869
supported mail this year and
we had 130 letters for activists in
380
00:35:08,869 --> 00:35:13,220
prison, which I find really great. I think
that's something we can all support.

VOC. Yes, you can have it. Here, the VOC.
387
00:35:40,380 --> 00:35:45,410
We only have 20 minutes left in total for
every team. So you know what to do.
388
00:35:45,410 --> 00:35:54,579
VOC1: Hurry up. Welcome, guys. So. Yeah.
We don't have as many statistics as usual.
389
00:35:54,579 --> 00:36:00,570
But we have some great stories too. We'll
hurry up. So this year in total, we
390
00:36:00,570 --> 00:36:07,790
covered 10 stages apart from the 5 stages
that we do usually for Congress. We had
391
00:36:07,790 --> 00:36:11,950
streams from the critical decentralisation
cluster, Sendezentrum, Wikipaka WG, Open
392
00:36:11,950 --> 00:36:20,020
Infrastructure Orbit, Chaos West. And in
total, we served 255 hours and 35 minutes
393
00:36:20,020 --> 00:36:26,640
of total talk time. So you know what to do
until the next Congress.

395
00:36:33,500 --> 00:36:40,730
VOC1: And of course, sustainability was a
big topic during this Congress. So part of
396
00:36:40,730 --> 00:36:48,720
what we have to do is stream reencoding so
you can watch it with the VP5 codec or use
397
00:36:48,720 --> 00:36:57,950
it at lower resolution. And so far we've
been using 4 Xeon-based machines and 2
398
00:36:57,950 --> 00:37:04,540
desktop machines. And thanks to hardware-
based encoding, we now replace this with a
399
00:37:04,540 --> 00:37:13,130
single laptop. As you can maybe read, this
is critical infrastructure now. And for
400
00:37:13,130 --> 00:37:18,510
all the streams, for 30 reencoding
streams, we are on a 45 watt power budget
401
00:37:18,510 --> 00:37:32,260
now. And as an added benefit, because we
also encode the master slides with
402
00:37:32,260 --> 00:37:36,990
hardware encoders, and hardware encoders
can generally use a higher profile that
403
00:37:36,990 --> 00:37:45,360
allows for better quality in real time,
you now get a better picture as well. So,
404
00:37:45,360 --> 00:37:50,990
yeah.

406
00:37:56,790 --> 00:38:04,579
VOC1: And of course, we had some minor
fuckups this year. We thought the audio
407
00:38:04,579 --> 00:38:11,030
setup was a bit less complex. But when we
checked rooms, we had buzzing everywhere.
408
00:38:11,030 --> 00:38:17,950
So we replaced some SDI lines with fiber
and turns out buzzing goes away. Then the
409
00:38:17,950 --> 00:38:26,040
PA sound console had a buggy DANTE card.
After you reboot them, the auxiliary out
410
00:38:26,040 --> 00:38:34,079
to the VOC cameras was muted. So that
messed up the particular talk that has
411
00:38:34,079 --> 00:38:40,830
been redone today, but other than that, we
are rather happy. And we figured that 3 of
412
00:38:40,830 --> 00:38:47,470
our audio mixers actually had broken
outputs. I don't know how we did that, but
413
00:38:47,470 --> 00:38:51,980
it clearly shows that they've been used on
one event or another during the last
414
00:38:51,980 --> 00:39:01,310
years, which is actually a good thing we
may think. On the Wikipaka stage, we did
415
00:39:01,310 --> 00:39:05,570
not use Ansible because there was sort of
a playground for us. But if you don't do
416
00:39:05,570 --> 00:39:14,390
things properly, well, then you run into
edge cases with things. And yeah. So I
417
00:39:14,390 --> 00:39:22,410
need to hurry up. And one virtualization
host suddenly started leaking memory. And
418
00:39:22,410 --> 00:39:26,463
so if you were affected by that during the
main talk season in the evening, we are
419
00:39:26,463 --> 00:39:31,350
very sorry about that. Updating the kernel
helped and we have no idea what happened.
420
00:39:31,350 --> 00:39:40,930
Yeah, and Icecast got stuck as well. And
some relive... so if you want to see talks
421
00:39:40,930 --> 00:39:48,970
later, that may not be possible because we
ran temporarily out of space. But if you
422
00:39:48,970 --> 00:39:54,230
watch this on media.ccc.de, and the talks
were not yet released, we have relive
423
00:39:54,230 --> 00:39:57,990
integration, so the talks show up in
media.ccc.de even though there is no
424
00:39:57,990 --> 00:40:03,880
proper release yet, for your convenience.
And main track and assemblies are now
425
00:40:03,880 --> 00:40:08,820
integrated in all events, so you don't
have to click through 4 separate events to
426
00:40:08,820 --> 00:40:15,609
find your favorite talk. And now I pass to
Pat to talk about VOCTOMIX 2.
427
00:40:15,609 --> 00:40:23,690
Pat: Yeah. Thank you. Okay. I have now 20
seconds, I think. I made a redesign of
428
00:40:23,690 --> 00:40:31,220
VOCTOMIX, it's now called VOC2MIX. And
Peter was doing that meme some weeks ago,
429
00:40:31,220 --> 00:40:37,589
because we had to switch to VOCTOMIX 2 and
we wanted to try it in 2 rooms. And in the
430
00:40:37,589 --> 00:40:45,060
night from day 0 to 1 we decided to do it
for every stage because the old solution
431
00:40:45,060 --> 00:40:55,640
was not working anymore. That was a little
bit hot, but it worked. And, the redesign
432
00:40:55,640 --> 00:41:01,790
caused the new UI, complete with some new
base features. We have now transitions
433
00:41:01,790 --> 00:41:10,390
where pictures are moving, and we have
insertions for blending text into the
434
00:41:10,390 --> 00:41:16,780
picture and we have a new audio mixing and
we are now proper A/V Sync in every case,
435
00:41:16,780 --> 00:41:19,760
I think.
[Filler, please remove me in amara]
436
00:41:19,760 --> 00:41:22,740
applause
[Filler, please remove me in amara]
437
00:41:22,740 --> 00:41:29,109
Pat: And some mixer angels were exploring
the software and they found some bonus
438
00:41:29,109 --> 00:41:36,310
features like random video distortion in
some cases, which I have to fix, I think.
439
00:41:36,310 --> 00:41:40,660
And the party mode where you click some
buttons and they are clicking without any
440
00:41:40,660 --> 00:41:46,849
doing of the user and everything is
flickering and they called it party mode.
441
00:41:46,849 --> 00:41:51,730
This is what the current pipeline looks
like. We have now over 200 gstreamer
442
00:41:51,730 --> 00:41:56,480
elements doing all this stuff to get your
pictures, which you are having on the
443
00:41:56,480 --> 00:42:03,480
stream and in the recordings. That's it.
VOC1: So, of course, there were some
444
00:42:03,480 --> 00:42:06,230
issues. I mean VOCTOMIX2 is essentially a
rewrite.
445
00:42:06,230 --> 00:42:11,930
H: You have to speed up a bit. Actually we
are stealing time from the other teams. I
446
00:42:11,930 --> 00:42:17,810
might call it a quit.
VOC1: OK OK OK. So...
447
00:42:17,810 --> 00:42:21,560
H: Pressure!
VOC1: Yes, I know. But you're not making
448
00:42:21,560 --> 00:42:32,280
things better. So one thing to mention: we
had to deploy a sweaty finger fix after
449
00:42:32,280 --> 00:42:39,869
the first talk started. Ok, here are your
stats, read them now, read them read them
450
00:42:39,869 --> 00:42:44,099
read them!
[Filler, please remove me in amara]
451
00:42:44,099 --> 00:42:45,165
applause
[Filler, please remove me in amara]
452
00:42:45,165 --> 00:42:55,800
H: Please give VOC a hand. Thank you. So
what's next? Oh, the Stage manager and
453
00:42:55,800 --> 00:43:02,920
Herald Operation Center. I'm part of it.
And we have 36 heralds, every one of them
454
00:43:02,920 --> 00:43:07,690
very eloquent and good-looking. Then we
have 70 stage managers and stage
455
00:43:07,690 --> 00:43:15,780
supporters. We had 150 shows on official
stages and the assemblies on top of it. We
456
00:43:15,780 --> 00:43:20,470
have one stage fright council yet for the
speakers who took care of at least six
457
00:43:20,470 --> 00:43:29,070
talks. And then we threw away over 100
hosting cards on day 1 only. So clearly,
458
00:43:29,070 --> 00:43:35,690
give a hand for the SHOC.
[Filler, please remove me in amara]
459
00:43:35,690 --> 00:43:41,180
applause
[Filler, please remove me in amara]
460
00:43:41,180 --> 00:43:45,180
H: So next, c3power. Your time.
Arif: So my name is Arif Guy. I am from
461
00:43:45,180 --> 00:43:49,770
the power team and from the radio
operation center. We make the power. We
462
00:43:49,770 --> 00:43:55,900
load five double trucks of shit out on
Sunday 15th. We deploy a lot of power
463
00:43:55,900 --> 00:44:02,950
boxes and many cables. So we have teardown
today so every help is needed. We have
464
00:44:02,950 --> 00:44:09,410
only one day to bring us back. The main
thing, we had the power meter that we made
465
00:44:09,410 --> 00:44:18,190
on the camp this year. We have two nice
setup on room H. You see the power factor
466
00:44:18,190 --> 00:44:25,560
is very bad. And the other one was the
Waffle Operation Center so you see they
467
00:44:25,560 --> 00:44:31,730
have a nice power factor. So please use
more ohmic devices like heaters, waffle
468
00:44:31,730 --> 00:44:42,960
iron or something. We only have 5 Seaview
to monitor Yolocolo. You have on
469
00:44:42,960 --> 00:44:48,849
c3power.top a Grafana link that also links
to the main Grafana to the NOC. Another
470
00:44:48,849 --> 00:44:57,520
nice thing we have on the lounge, I have a
video here. It started now. You can see
471
00:44:57,520 --> 00:45:06,349
the current on all 3 phases to the audio
and you can see the audio from the lounge.
472
00:45:06,349 --> 00:45:16,220
recorded music from the lounge
[Filler, please remove me in amara]
473
00:45:16,220 --> 00:45:25,190
Arif: It's very nice.
[Filler, please remove me in amara]
474
00:45:25,190 --> 00:45:28,140
recorded music from the lounge
[Filler, please remove me in amara]
475
00:45:28,140 --> 00:45:33,440
Arif: As you see, the only thing is...
[Filler, please remove me in amara]
476
00:45:33,440 --> 00:45:36,400
applause
[Filler, please remove me in amara]
477
00:45:36,400 --> 00:45:44,670
Arif: Use more bass, or make more current.
Later we can show you another slide. Go to
478
00:45:44,670 --> 00:45:56,420
next slide please. So for the radio team
we have 120 portable radios. We have
479
00:45:56,420 --> 00:46:01,670
updated them to a new firmware, and a new
programming software with a new feature
480
00:46:01,670 --> 00:46:07,440
that is a lot slower than the last
version. Very nice. 50 bring-your-own-
481
00:46:07,440 --> 00:46:13,160
device radios. 5 dead radios from the
camp. 2 dead from 36c3. 2 dead repeaters
482
00:46:13,160 --> 00:46:18,410
from the camp. 1 dead on arrival on this
stage. 3 rental repeaters from 2
483
00:46:18,410 --> 00:46:24,460
companies, one we picked up in Hannover
just before the Congress, and even the
484
00:46:24,460 --> 00:46:30,470
windows PC crashed down dead on arrival.
Business as usual. So, next team!
485
00:46:30,470 --> 00:46:42,760
H: Thank you! So, the next is c3subtitles.
I think it's Amy and Julia. Amy. They are
486
00:46:42,760 --> 00:46:51,760
not. C3SOS. S.O.S. It's you. Okay. Okay.
Sorry. Oh, I'm sorry. Not the subtitles.
487
00:46:51,760 --> 00:46:55,370
It's well, sustainability. Your stage, go
for it. Here, feel free.
488
00:46:55,370 --> 00:47:03,819
Amy: Hello. Okay, hi. My name is Amy, I'm
part of the c3sustainability team. I only
489
00:47:03,819 --> 00:47:08,880
have four slides, so I'll be very quick.
You can see, the first of our biggest
490
00:47:08,880 --> 00:47:13,650
projects was the drinking water
dispensers. So for angels, we had drinking
491
00:47:13,650 --> 00:47:17,880
water from a dispenser rather than from
bottles and they could refill their
492
00:47:17,880 --> 00:47:22,060
bottles. We go through some stats there.
So when we started planning how difficult
493
00:47:22,060 --> 00:47:27,250
it was to implement it, the locations, and
how many volunteers, satisfaction was very
494
00:47:27,250 --> 00:47:32,250
high for this one. So thank you to c3geld
who really helped organize the water
495
00:47:32,250 --> 00:47:36,830
dispensers with us. We're very happy. They
were really great. Please give them a
496
00:47:36,830 --> 00:47:38,830
round of applause.
[Filler, please remove me in amara]
497
00:47:38,830 --> 00:47:39,910
applause
[Filler, please remove me in amara]
498
00:47:39,910 --> 00:47:43,800
Amy: Thank you. The next one was a give
and take electronic box. So we wanted to
499
00:47:43,800 --> 00:47:47,530
encourage people not to throw away their
electronics. Of course, they can be
500
00:47:47,530 --> 00:47:52,859
recycled. So we have deployed 10 boxes.
You can find them in the sticker stations.
501
00:47:52,859 --> 00:47:58,440
And we did this in collaboration with the
hardware hacking area. Thank you. And
502
00:47:58,440 --> 00:48:00,440
other assemblies. Oh, wow, you are really
fast.
503
00:48:00,440 --> 00:48:02,440
H: Yes I am.
Amy: Okay!
504
00:48:02,440 --> 00:48:05,960
H: Others are waiting!
Amy: Okay. So the last one I wanted to go
505
00:48:05,960 --> 00:48:10,780
through. We have two initiatives on this
one. I'm sorry for the trashy picture
506
00:48:10,780 --> 00:48:17,240
there. We have organic bins in the halls.
It was very, very difficult to do this.
507
00:48:17,240 --> 00:48:21,339
But actually it was quite satisfactory.
But I would say there is room for
508
00:48:21,339 --> 00:48:26,930
improvement there. And there was also an
initiative for recycling cigaret butts. So
509
00:48:26,930 --> 00:48:29,480
we actually had two people go round,
collect your cigaret butts and they will
510
00:48:29,480 --> 00:48:37,460
be recycled into cool ashtrays. What a
success! Thank you so much to everyone who
511
00:48:37,460 --> 00:48:40,750
collaborated with us. We couldn't do out
without your help.
512
00:48:40,750 --> 00:48:44,100
H: Thank you. Your applause, please.
[Filler, please remove me in amara]
513
00:48:44,100 --> 00:48:46,670
applause
[Filler, please remove me in amara]
514
00:48:46,670 --> 00:48:51,089
H: So unfortunately, the c3sign is not
coming. So just take a look at those
515
00:48:51,089 --> 00:48:57,400
pictures while I go through them. And now
the next one is C3 Assemblies. Here, take
516
00:48:57,400 --> 00:49:03,960
this one. Thank you. Be quick.
Pingu: Hi, my name is Pingu. I'm here for
517
00:49:03,960 --> 00:49:11,460
the assembly team. And I just want to ask,
give a hand who hasn't found his assembly
518
00:49:11,460 --> 00:49:19,020
on day zero or day one? So then give a big
applause to c3nav because they really
519
00:49:19,020 --> 00:49:28,690
helped us a lot. Because without them, it
wasn't able to do this event just for us.
520
00:49:28,690 --> 00:49:37,329
Because for some figures we had 419
assemblies to place on this area which is
521
00:49:37,329 --> 00:49:45,060
about 35000 square meters. We had 3000
tables all over, 2500 in the assemblies,
522
00:49:45,060 --> 00:49:53,820
with 6000 chairs. And here, please give a
big applause to the C3Möbelhaus or IKEA as
523
00:49:53,820 --> 00:49:57,359
you call it.
[Filler, please remove me in amara]
524
00:49:57,359 --> 00:50:00,520
applause
[Filler, please remove me in amara]
525
00:50:00,520 --> 00:50:07,930
Pingu: Because the Möbelhaus basically
placed all the tables in a magic night on
526
00:50:07,930 --> 00:50:16,990
basically day -2. And they will disappear
with the help of C3Möbelhaus today. We
527
00:50:16,990 --> 00:50:25,450
assigned the last assembly on day zero at
22:00 and we started our work in mid-
528
00:50:25,450 --> 00:50:33,460
October with weekly meetings. And yeah, as
you can see, it was a lot of work and...
529
00:50:33,460 --> 00:50:36,119
Oh.
H: Thank you.
530
00:50:36,119 --> 00:50:44,950
Pingu: Thank you. And just one thing, for
teardown, for tearing down the assemblies,
531
00:50:44,950 --> 00:50:54,010
please stack the chairs on the assembly
but leave every chair and every table on
532
00:50:54,010 --> 00:51:13,900
the assembly, we will get rid of them.
H: Thanks a lot. Your applause. So the
533
00:51:13,900 --> 00:51:20,569
next ones are... Les prochains, ce sont
les gens de c3lingo, voilà, vos tours!
534
00:51:20,569 --> 00:51:26,161
c3lingo 1: Hallo! Schön euch mal (...) Wir
sind übersetzet. (...)
535
00:51:26,161 --> 00:51:32,190
German>
Oh, sorry. Well, I'm also fine with that.
536
00:51:32,190 --> 00:51:35,540
We translated all the German talks into
English. All the English talks into
537
00:51:35,540 --> 00:51:40,170
German. All in all, fifteen thousand
minutes in seven different target
538
00:51:40,170 --> 00:51:45,089
languages. And here is from the second
language team, who talk all the non-
539
00:51:45,089 --> 00:51:49,480
English and non-German things.
c3lingo 2: Okay. So basically we did have
540
00:51:49,480 --> 00:51:57,450
about 1/3 of the talks were translated to
French. Yeah. You can read the rest. And
541
00:51:57,450 --> 00:52:00,900
we even have currently, exactly, right
now, another one which is translated into
542
00:52:00,900 --> 00:52:05,060
Swabian. So if you want to listen into it.
[Filler, please remove me in amara]
543
00:52:05,060 --> 00:52:07,030
applause
[Filler, please remove me in amara]
544
00:52:07,030 --> 00:52:11,491
c3lingo 2: Which means that if you were
listening to a talk, there is 2 chance out
545
00:52:11,491 --> 00:52:17,710
of 3 that it was translated not only once,
but twice. Into either French, Spanish,
546
00:52:17,710 --> 00:52:21,900
Russian, or Polish. One special mention
for the Russian and Polish teams, that was
547
00:52:21,900 --> 00:52:25,010
their first time this year. So one big
round of applause for them, please.
548
00:52:25,010 --> 00:52:29,790
applause
[Filler, please remove me in amara]
549
00:52:29,790 --> 00:52:36,760
c3lingo 2: And one more big thank about
for the guys who brought the cough candies
550
00:52:36,760 --> 00:52:41,380
and cough drops in the booth. That's a
lifesaver. Thanks.
551
00:52:41,380 --> 00:52:48,559
H: Thank you. Merci beaucoup. So we have
some heart operation going on here. You
552
00:52:48,559 --> 00:52:50,790
have to switch it or not? Oh, you're good
with computers.
553
00:52:50,790 --> 00:52:54,790
laughing
[Filler, please remove me in amara]
554
00:52:54,790 --> 00:53:00,829
H: He just mimicks something. So
c3infrastructure from the subtitles. Your
555
00:53:00,829 --> 00:53:09,430
stage. Yeah. My microphone. Ha ha.
td: So, thanks. Just a quick look into the
556
00:53:09,430 --> 00:53:13,980
subtitles. So what do we actually do when
we subtitle a talk? Well, first of all, we
557
00:53:13,980 --> 00:53:18,600
take the video from the C3VOC and put it
through speech recognition just to get a
558
00:53:18,600 --> 00:53:24,290
rough transcript that we can then give to
angels to actually correct, because, well,
559
00:53:24,290 --> 00:53:29,569
machine speech recognition doesn't work so
good at all. And then once we have a
560
00:53:29,569 --> 00:53:34,390
working transcript that humans have looked
at, we put that through auto-timing, which
561
00:53:34,390 --> 00:53:38,220
just takes the transcript and aligns that
with the audio, and that usually works
562
00:53:38,220 --> 00:53:43,010
pretty well. And, well, once that is
finished, then we actually have working
563
00:53:43,010 --> 00:53:47,299
subtitles, but we give them to angels for
another round of review just to fix any
564
00:53:47,299 --> 00:53:51,980
mistakes that got overlooked. And maybe
sometimes the timing needs to be adjusted.
565
00:53:51,980 --> 00:53:55,720
And then, when that is done, well, the
subtitle is released. And actually one of
566
00:53:55,720 --> 00:54:01,010
our angels did a nice chart about all this
process that you can see here. It all
567
00:54:01,010 --> 00:54:09,800
sounds better, so thank you for that.
Well, no presentation without graphs. As
568
00:54:09,800 --> 00:54:12,420
you can see, the important thing is
really: everything goes up and to the
569
00:54:12,420 --> 00:54:19,440
right. On the bottom here we have finished
seconds of transcribed talks. So this is
570
00:54:19,440 --> 00:54:22,300
really completed subtitles here. And it
starts already quite high because it
571
00:54:22,300 --> 00:54:28,470
includes all the Congresses before. Then
we have stuff that has been reviewed in
572
00:54:28,470 --> 00:54:34,790
orange. Stuff that has been timed but not
reviewed yet in yellow. And transcribed
573
00:54:34,790 --> 00:54:44,609
but not yet timed stuff in green. All in
all, we had 144 distinct angels. Yeah, I
574
00:54:44,609 --> 00:54:53,140
need to hurry up. 71% of which took 2
shifts and 10% took 7 or more shifts. So
575
00:54:53,140 --> 00:54:58,500
433 hours of work for 126 hours of
material. And so far we've had 6 releases
576
00:54:58,500 --> 00:55:02,859
from this Congress and then lots of hours
worked. All of these numbers are at least
577
00:55:02,859 --> 00:55:07,380
as high as last year's numbers, so good,
thanks. When you have transcripts, you can
578
00:55:07,380 --> 00:55:11,200
do cool stuff with that. So, for example,
generate word clouds to see what people
579
00:55:11,200 --> 00:55:15,190
like. And this case, people seem to like
people and questions and time, which we
580
00:55:15,190 --> 00:55:20,610
don't have any here. So. Well, how do we
actually keep track of all this
581
00:55:20,610 --> 00:55:26,070
complicated stuff? Well, we use a state-
of-the-art NoSQL lock-free columnar data
582
00:55:26,070 --> 00:55:32,390
store, like many of the other teams also
do. And well, thank you all of our angels
583
00:55:32,390 --> 00:55:38,070
for your hard work. And also thanks for
the Heaven for supporting us. And then,
584
00:55:38,070 --> 00:55:41,440
well, if you if you feel bored between
Congresses, you can still continue to work
585
00:55:41,440 --> 00:55:44,200
on transcripts. You have all the
informations here, these slides will be
586
00:55:44,200 --> 00:55:47,219
online, follow us on Twitter. And thank
you.

H: Please do your thing again, like your
thing again, like do *mimicks
589
00:55:54,420 --> 00:55:57,630
something*. Take your laptop.

591
00:55:59,869 --> 00:56:04,400
H: So this was the last one. I think I
will try my best to do something like this
592
00:56:04,400 --> 00:56:09,010
too. Actually I'm not good with computers,
but I know someone who is and who takes
593
00:56:09,010 --> 00:56:15,070
very great care of everyone of us. So one
of my highlights of every Congress, feel
594
00:56:15,070 --> 00:56:25,079
free, the LOC!
LOC: Hello. I'm the stand-in for LOC. As
595
00:56:25,079 --> 00:56:30,450
with all good projects, they're too busy
for documentation. They're packing. So LOC
596
00:56:30,450 --> 00:56:36,270
doesn't have anything. I'm more of the
Department of Health and Safety again. So
597
00:56:36,270 --> 00:56:40,900
for everyone: we have the message from
CERT that there were no work-related
598
00:56:40,900 --> 00:56:47,660
accidents that caused real harm. The odd
broken Mate bottle maybe. But thank you
599
00:56:47,660 --> 00:56:56,849
for having built a city again safely and
orderly, even with all the chaos. For the
600
00:56:56,849 --> 00:57:01,069
people who are driving, please make sure
that the drugs wear off and that you get
601
00:57:01,069 --> 00:57:08,220
some sleep and for all people riding
along, please keep the guys awake. That
602
00:57:08,220 --> 00:57:11,710
would be greatly appreciated. Go home
safely. Thank you very much.

604
00:57:15,960 --> 00:57:25,660
H: So. Wow, ah, OK. So I'm very sorry to
have to rush some teams and I'm very sorry
605
00:57:25,660 --> 00:57:29,160
that we don't have any time left. We are 1
minute over and I promised the teardown
606
00:57:29,160 --> 00:57:36,530
crew to not do overtime. So please, please
give all the teams their respect and clap
607
00:57:36,530 --> 00:57:40,240
and tramp as loud as you can for now to
finish!
608
00:57:40,240 --> 00:57:43,280
standing ovation
[Filler, please remove me in amara]
609
00:57:43,280 --> 00:57:50,280
H: Everything! They did! For us! We did!
For them! Why are you still sitting? You
610
00:57:50,280 --> 00:57:54,280
have to leave. Thank you. From the
c3infrastructure Review. Goodbye.
