Herald: Hello and welcome to[br]Infrastructure Review. This review is
9:59:59.000,9:59:59.000
being translated into a lot of languages[br]and we don't know yet which one, but the
9:59:59.000,9:59:59.000
c3lingo team will be on stage and will[br]tell us how and what it did. I'd like to
9:59:59.000,9:59:59.000
start, as always and every year, with the[br]NOC, right. So please give the NOC a hand.
9:59:59.000,9:59:59.000

Momo: All right, everyone, welcome to the[br]State of the Internet manufacture report.
9:59:59.000,9:59:59.000
This is JC, I'm Momo and we're going to[br]talk to you about what we did this year
9:59:59.000,9:59:59.000
for the network. So obviously, organizing[br]Congress is a quite tedious task. Took us
9:59:59.000,9:59:59.000
about six months of pre-planning. We came[br]in on the 15th, did a fiber day and then
9:59:59.000,9:59:59.000
it took us from the 18th and will take us[br]till tomorrow to tear everything down with
9:59:59.000,9:59:59.000
like 20 to 40 people. And we'll be busy[br]wiping every device because that is
9:59:59.000,9:59:59.000
actually what we do every year. We delete[br]everything. There are no logs leaving this
9:59:59.000,9:59:59.000
building and this will take us probably[br]the next 24 hours. So yeah, for the usual
9:59:59.000,9:59:59.000
numbers. Edge capacity: this year because[br]you didn't use all the Internet last year,
9:59:59.000,9:59:59.000
we only brought you 300 gigs, but that was[br]fine as well, I suppose. We got 100 gig
9:59:59.000,9:59:59.000
from HLKomm here in Leipzig, 100 gig from[br]Deutsche Telekom and as well as 100 gig
9:59:59.000,9:59:59.000
from BCIX which we got via DWDM wave to[br]Berlin. In the core we used Juniper
9:59:59.000,9:59:59.000
MX960s, MX480s, MX204s and QFX10002 in the[br]yolocolo. Basically all the halls were
9:59:59.000,9:59:59.000
connected via a 200 gig link and yolocolo[br]had three times 100 gig. As probably the
9:59:59.000,9:59:59.000
last five or so years, we're using IS-IS[br]and BGP for our protocols of choice. And
9:59:59.000,9:59:59.000
this year we also first off rejected RPKI[br]invalid routes and secondly applied for
9:59:59.000,9:59:59.000
the first time at congress BCP38 ingress[br]filtering to be a good internet citizen
9:59:59.000,9:59:59.000
and not to allow you to spoof IP[br]addresses. So yeah, that was nice. As
9:59:59.000,9:59:59.000
Congress keeps on growing, we have 2500[br]tables somewhere around the building in
9:59:59.000,9:59:59.000
all the assemblies, but we only have 300[br]switches. So sorry if you had to bring a
9:59:59.000,9:59:59.000
long cable and if you have switches to[br]spare with 10 gig uplinks and POE+, feel
9:59:59.000,9:59:59.000
free to donate them to us. Access and Wi-[br]Fi. We had like 300 access switches. We
9:59:59.000,9:59:59.000
are obviously again running Aruba Wi-Fi[br]controllers. This year, like at camp we
9:59:59.000,9:59:59.000
had a few 802.1x access points, more on[br]that later. We tried to use Juniper vMX to
9:59:59.000,9:59:59.000
route the Wi-Fi traffic. And had quite a[br]shitload of switches, most of them from
9:59:59.000,9:59:59.000
Juniper, some Cisco 2960s, some Brocades[br]which are new to us, and some crappy old
9:59:59.000,9:59:59.000
HPE stuff which is basically configured[br]for us to work like a brick you get from
9:59:59.000,9:59:59.000
like eBay or whatnot. We had a few[br]incidents this year we'd like to talk
9:59:59.000,9:59:59.000
about. First off, we had, I'm not sure if[br]any of you noticed, quite a lot of packet
9:59:59.000,9:59:59.000
loss and missing router advertisements on[br]the Wi-Fi. This was caused by some weird
9:59:59.000,9:59:59.000
Juniper vMX behavior. We couldn't figure[br]out what it was. So we had them running in
9:59:59.000,9:59:59.000
a redundant VRRP setup. We shut down one[br]of them and then it worked. So yeah, fuck
9:59:59.000,9:59:59.000
redundancy. There was a pixelflut client[br]which somehow messed up his IP address and
9:59:59.000,9:59:59.000
caused a broadcast storm which took down[br]most parts of Hall 2. We found them, shut
9:59:59.000,9:59:59.000
it down and deployed storm control to all[br]our access switches. Yeah, to the Congress
9:59:59.000,9:59:59.000
motto resource exhaustion: someone was[br]running aggressive zmap scanning over the
9:59:59.000,9:59:59.000
whole internet, came by our Wi-Fi access[br]controller and caused a state table
9:59:59.000,9:59:59.000
exhaustion. And that brought it down. We[br]null-routed the source and yeah, there was
9:59:59.000,9:59:59.000
this issue. So thank you to whoever was[br]that. And in the morning of day 3, we had
9:59:59.000,9:59:59.000
another issue with Juniper vMX where it[br]forgot it had a network card. We rebooted
9:59:59.000,9:59:59.000
it and everything was fine again. So yeah,[br]some numbers. You actually managed to use
9:59:59.000,9:59:59.000
more bandwidth, thank you.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: But it's still only 20% of our uplink[br]capacity. So use more. 20% of that was
9:59:59.000,9:59:59.000
IPv6, which is good, but could be more. We[br]had like 11000 clients into Wi-Fi. 86% 5
9:59:59.000,9:59:59.000
GHz, 96% in a peak.[br]We had eleven 802.11ax clients. Our
9:59:59.000,9:59:59.000
favorite one was obviously the one with[br]the lovely hostname ILOVETHENOC. So yeah,
9:59:59.000,9:59:59.000
about that number we have, 96% 5 GHz[br]obviously shows us that we are finally at
9:59:59.000,9:59:59.000
the point where we can say: thank you 2.4[br]GHz, it was nice. Goodbye.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: Also, obviously, thank you to our[br]sponsors. We couldn't do this if we would
9:59:59.000,9:59:59.000
not get like 10 millions, of list price[br]obviously, of equipment and loan and quite
9:59:59.000,9:59:59.000
a lot of services. So give them a round of[br]applause as well. Thank you.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: And obviously NOC not only stands for[br]Network Operation Center, but if you
9:59:59.000,9:59:59.000
extend it, it is No CO2. So we believe in[br]green power and clean traffic and
9:59:59.000,9:59:59.000
therefore we obviously see that[br]sustainability is a great part of our
9:59:59.000,9:59:59.000
role. This is why we even use old crappy[br]HP switches to cut our lines for our
9:59:59.000,9:59:59.000
tchunk to serve your cheese boards,[br]whatever you need.
9:59:59.000,9:59:59.000
laughter[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: Also...[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: Also, we somehow estimated what our[br]network will run us in CO2 and that was
9:59:59.000,9:59:59.000
about 11 tons. We're not very good with[br]mass and not very good with CO2 emissions,
9:59:59.000,9:59:59.000
but this was roughly what we came up with.[br]And to make Congress or the world a bit
9:59:59.000,9:59:59.000
better place, we actually offset all our[br]CO2 and bought eleven tons of CO2
9:59:59.000,9:59:59.000
emissions. And now Frederick is gonna tell[br]you how we got all those numbers.
9:59:59.000,9:59:59.000
Frederick: Yeah, as a good internet[br]manufacture, we also do monitoring a lot
9:59:59.000,9:59:59.000
and we run our own Prometheus server[br]inside. You probably know the dashboard
9:59:59.000,9:59:59.000
that we propagate all over the internet[br]and that's powered by Prometheus. We have
9:59:59.000,9:59:59.000
an internal Grafana that is part of this[br]whole ecosystem. And if you are a little
9:59:59.000,9:59:59.000
bit of a nerd, you might have clicked on[br]the dashboard sections and seen that there
9:59:59.000,9:59:59.000
are more dashboards than this. We fill our[br]Prometheus with lots of different sources:
9:59:59.000,9:59:59.000
we get SNMP data from, and screw SNMP, but[br]it does a quite good job at getting all
9:59:59.000,9:59:59.000
the insights we need from all the network[br]equipment. We have node_exporter, influx
9:59:59.000,9:59:59.000
and all that, but we got a decent amount[br]of data from everyone in the Congress
9:59:59.000,9:59:59.000
ecosystem and we had that at camp as well[br]where we got the water pressure of the
9:59:59.000,9:59:59.000
showers. And we get the colo power, which[br]also helps with estimating the CO2
9:59:59.000,9:59:59.000
footprint. And everything is being[br]configured by Netbox, which is a tool that
9:59:59.000,9:59:59.000
is an asset database. And as I said, we[br]have lots of dashboards and graphs. Of
9:59:59.000,9:59:59.000
course, the public one where you can see[br]lots of different things from everyone.
9:59:59.000,9:59:59.000
This is only part of it. If you scroll[br]down on the dashboard, you see a lot more.
9:59:59.000,9:59:59.000
But this helps everyone to have a good[br]understanding of what is happening
9:59:59.000,9:59:59.000
currently. And we even draw a nice little[br]Christmas trees on the Wi-Fi traffic for
9:59:59.000,9:59:59.000
you. That is mostly because it's a router-[br]on-a-stick and we cannot measure it
9:59:59.000,9:59:59.000
correctly. We have an internal dashboard[br]which gives us a little bit of a status
9:59:59.000,9:59:59.000
for build-up mostly: which switches and[br]routers are up? And that gives us a very
9:59:59.000,9:59:59.000
quick sight of all the devices that are[br]out there. What's broken? What's not
9:59:59.000,9:59:59.000
broken? We improved it a little and now[br]have alarms so someone can look at stuff
9:59:59.000,9:59:59.000
and see if things are broken, run out[br]there and fix it. We also built
9:59:59.000,9:59:59.000
weathermaps. As you can see that's a[br]little bit of a mess. But we couldn't do
9:59:59.000,9:59:59.000
it better because the graphing library[br]doesn't allow us to do it better. If
9:59:59.000,9:59:59.000
someone has a good idea to do it better in[br]Grafana or anywhere else with sources from
9:59:59.000,9:59:59.000
Prometheus, please come to us, we're happy[br]to talk. But this shows our core and all
9:59:59.000,9:59:59.000
the links between it and how much capacity[br]is being used. Red indicates that it's
9:59:59.000,9:59:59.000
used more heavily. We also have that for[br]the yolocolo. And all the traffic around
9:59:59.000,9:59:59.000
it as well. And, yeah, teardown starts[br]now. Please don't touch our equipment. And
9:59:59.000,9:59:59.000
if you want to come and help, please come[br]to Hall 4 and get in touch. We always need
9:59:59.000,9:59:59.000
helping hands. But please in an organized[br]way don't disassemble switches or access
9:59:59.000,9:59:59.000
points. We have lists and everything. We[br]need to account for everything. So please
9:59:59.000,9:59:59.000
come to Hall 4 if you want to help. And[br]yes, use more bandwidth and offset more
9:59:59.000,9:59:59.000
CO2. Thank you.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: So thanks a lot. Actually, because[br]you're clearly the backbone or one of
9:59:59.000,9:59:59.000
those many backbones of the conference, is[br]there any Q? Let's do a Q&A for like one
9:59:59.000,9:59:59.000
or two questions.[br]Is anyone having a question right now?
9:59:59.000,9:59:59.000
Someone is standing up. Right, microphone[br]number one, please.
9:59:59.000,9:59:59.000
Q: Hey, we've absolutely don't ...[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: Nearer, nearer.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
Q: We've absolutely done bcp38 in[br]previous years, by the way.
9:59:59.000,9:59:59.000
M: Sorry for what I said then, I'm sorry.[br]Q: So I wanted to correct the record.
9:59:59.000,9:59:59.000
We've been good netizens in previous years[br]as well.
9:59:59.000,9:59:59.000
H: Oh, you're right. Thank you. Was there[br]another question or something else to
9:59:59.000,9:59:59.000
correct them? Because they clearly don't[br]know what they're doing.
9:59:59.000,9:59:59.000
laughter[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: Yeah. Feel free. Microphone number two.[br]Q: So if 2.4GHz is over, what's going to
9:59:59.000,9:59:59.000
happen to all of the ESP32 in various IoT[br]devices? Are they going to have a home
9:59:59.000,9:59:59.000
here next year?[br]M: They'll definitely have a home. But as
9:59:59.000,9:59:59.000
usual, we cannot support it as good as we[br]can on 5GHz because obviously this band is
9:59:59.000,9:59:59.000
overused and not even remotely suited for[br]that amount of clients we put on it.
9:59:59.000,9:59:59.000
Q: A follow-up for the ESP32. How exactly[br]can you locate them through the wireless
9:59:59.000,9:59:59.000
if they are lost?[br]M: Well, we can't. We can basically look
9:59:59.000,9:59:59.000
at which access point they are, and then[br]if someone really would want to, we could
9:59:59.000,9:59:59.000
start triangulation, but we've never done[br]that before. So yeah, we can just pin them
9:59:59.000,9:59:59.000
roughly to an access point.[br]H: Maybe we can ask c3nav next time. So
9:59:59.000,9:59:59.000
please give the NOC a hand.[br]Thank you.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: So, the next team up is the POC. Do we[br]have to click this? Use more bandwidth,
9:59:59.000,9:59:59.000
I'm going to try. Ah! Thank you. Your[br]stage.
9:59:59.000,9:59:59.000
Garvin: Thanks.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
Maria: Hi, my name is Maria.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
G: Hi, and I'm Garvin and we're from Phone[br]Operation Center and we want to talk a bit
9:59:59.000,9:59:59.000
about the phone infrastructure at this[br]event.
9:59:59.000,9:59:59.000
M: Yeah. So we arrived at day -6 and[br]planned on hacking some things
9:59:59.000,9:59:59.000
and socializing and we planned a team[br]event, but then everything was different.
9:59:59.000,9:59:59.000
G: Yeah. When we arrived, I went into the[br]NOC office and they said to me, "Ja, CCL
9:59:59.000,9:59:59.000
is up, internet is up, everything is just[br]working nicely. You can start hook up your
9:59:59.000,9:59:59.000
telephony system right now." And I was[br]like, whoa. So thanks a lot NOC. Really
9:59:59.000,9:59:59.000
great performance this year, we were[br]amazed. Nobody expected that it works so
9:59:59.000,9:59:59.000
well.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: Yeah. So we put up the first antennas[br]and then we decided to have our team event
9:59:59.000,9:59:59.000
anyway. And yeah, so we did a lot of[br]things. So we handed out 150 orga loan
9:59:59.000,9:59:59.000
DECTs and we deployed 51 SIP telephones.[br]We also deployed 67 antennas and we had a
9:59:59.000,9:59:59.000
POC party on day three until 7:30 a.m.[br]G: So you can see almost everything is
9:59:59.000,9:59:59.000
done. I guess the remaining things are not[br]that important. So this is the overview of
9:59:59.000,9:59:59.000
DECT coverage at the event. Only level[br]zero, because otherwise I think it would
9:59:59.000,9:59:59.000
be overcrowded to show. Just so that you[br]can get a rough impression on how many
9:59:59.000,9:59:59.000
antennas we deployed in order to give you[br]this DECT coverage. That you can be
9:59:59.000,9:59:59.000
reached almost everywhere in the event and[br]that you can see how our tooling looks
9:59:59.000,9:59:59.000
like, where we see how good the antennas[br]see each other, and that we can see that
9:59:59.000,9:59:59.000
seamless handover work so that you can[br]start at our desk, walk through the area,
9:59:59.000,9:59:59.000
into the lounge and just continue talking.[br]And oh, there are also some antennas that
9:59:59.000,9:59:59.000
are outside of the building. What could[br]that be?
9:59:59.000,9:59:59.000
M: That is our hotel DECT. And you can see[br]a typical hotel DECT installation on the
9:59:59.000,9:59:59.000
photo. And people got really confused[br]about it because we also had DECT coverage
9:59:59.000,9:59:59.000
at main station.[br]G: Yeah. So I got a call roughly at 4:00
9:59:59.000,9:59:59.000
p.m. in the morning.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
G: And somebody told me. Oh, my DECT rang.[br]Why? Now I need to turn it off at the
9:59:59.000,9:59:59.000
night. Why did you do this?[br]M: Yeah. So we also had problems. We have
9:59:59.000,9:59:59.000
a new feature since Camp where you can see[br]your DECT devices and can assign them to
9:59:59.000,9:59:59.000
your number before you even arrive, and[br]then everything is set up and you don't
9:59:59.000,9:59:59.000
have to call your token anymore. And[br]people get really confused because they
9:59:59.000,9:59:59.000
would call their token anyway and it calls[br]it invalid. So we had to explain a lot of
9:59:59.000,9:59:59.000
this unexpected simplicity to them.[br]G: And then we had a battery issue this
9:59:59.000,9:59:59.000
year. We had not enough batteries and, you[br]know, batteries are always empty in the
9:59:59.000,9:59:59.000
phones when it's the most important. So we[br]were thinking what what can we do about
9:59:59.000,9:59:59.000
that?[br]M: So we build a new device. That's our
9:59:59.000,9:59:59.000
microwave and it can also charge devices.[br]So, many thanks to C3Power, because they
9:59:59.000,9:59:59.000
helped us with tooling and actually they[br]have expertise to put power cables on
9:59:59.000,9:59:59.000
devices like this. Thank you very much.[br][Filler, please remove me in amara]

9:59:59.000,9:59:59.000
G: In the last years we were often asked[br]"how expensive is your service actually?".
9:59:59.000,9:59:59.000
So we decided that we now provide invoices[br]so you can see how expensive our services
9:59:59.000,9:59:59.000
are and we send out a lot of invoices. And[br]we got paid some money. But as you can see
9:59:59.000,9:59:59.000
on the invoices, most is sponsored by CCC.[br]M: Yeah. And people also paid with Mate
9:59:59.000,9:59:59.000
which is really awesome.[br]G: Yeah. And also people have invoices on
9:59:59.000,9:59:59.000
a fraction of a cent and they got quite[br]creative on how they can pay us.
9:59:59.000,9:59:59.000

applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: So here are some more stats. We have[br]7473 registered extensions.
9:59:59.000,9:59:59.000
G: Oh, we didn't remove this. So we were[br]thinking on how to compare this with
9:59:59.000,9:59:59.000
things and we were looking at villages in[br]Saarland and then we thought, this is a
9:59:59.000,9:59:59.000
stupid comparison, but we didn't remove[br]this.
9:59:59.000,9:59:59.000
M: So there were 5021 attached DECT phones[br]and 3251 concurrent DECT phones. Which is
9:59:59.000,9:59:59.000
about more than 1000 more than last year.[br]G: So thanks a lot for using DECT.
9:59:59.000,9:59:59.000
M: Yeah. We had...[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: There were also max 120 calls in[br]parallel, and we had more than 300
9:59:59.000,9:59:59.000
thousand calls in total. That's also[br]really, really much. We had five eating
9:59:59.000,9:59:59.000
meetings at heaven, the angel eating[br]place, and there were an average of 42
9:59:59.000,9:59:59.000
eating meeting live viewers. We had two[br]lectures. You can see them on media.ccc.de
9:59:59.000,9:59:59.000
and we had 23 super fast charged phones in[br]our microwave.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
G: Like the NOC, we also had to deal a bit[br]with issues during the event, and actually
9:59:59.000,9:59:59.000
there were some DDOS attack on our account[br]system and somebody configured over 4000
9:59:59.000,9:59:59.000
extensions with really stupid names. And[br]it took us quite a while to get rid of
9:59:59.000,9:59:59.000
them again cleanly from the system because[br]the synchronization turned out to be
9:59:59.000,9:59:59.000
really slow. So you can see it took us a[br]while to get them removed again. So we can
9:59:59.000,9:59:59.000
only say, you all know it's a hacker[br]congress, but it's kind of stupid to hack
9:59:59.000,9:59:59.000
your own infrastructure.[br][Filler, please remove me in amara]

applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
G: So as a consequence of this, we only[br]allow now only 50 extensions per account
9:59:59.000,9:59:59.000
and per event. If you think you need more,[br]feel free to contact us if you have a
9:59:59.000,9:59:59.000
valid use case.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: So every device has an IPEI that is[br]like a MAC address and we ask the
9:59:59.000,9:59:59.000
responsible institution to give us the[br]manufacturer. But it's really secret. So
9:59:59.000,9:59:59.000
they don't give it to us. So we ask you[br]for help. Please enter the models of your
9:59:59.000,9:59:59.000
devices for your phones. And then we can[br]match to the IPEI and get some data to
9:59:59.000,9:59:59.000
build more awesome features for you.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
G: This would really help us. And the only[br]way for us is to crowdsource it because it
9:59:59.000,9:59:59.000
seems to be super secret. Whatever.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: You can find it in guru3 on the device[br]page and there's this little pen. And if
9:59:59.000,9:59:59.000
you click on it, then you can enter the[br]model.
9:59:59.000,9:59:59.000
G: Thanks upfront. And yep, that's from[br]us, and I guess now we have a little time
9:59:59.000,9:59:59.000
for you to ask questions.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: Great. So, any questions for the POC? I[br]don't see... were they correct or do we
9:59:59.000,9:59:59.000
have to...? Ah, someone is getting up. So[br]microphone number 1, please.
9:59:59.000,9:59:59.000
Q: Yes, a few years ago there was a[br]translation service via DECT. Is the
9:59:59.000,9:59:59.000
capacity enough to service also this[br]crowd?
9:59:59.000,9:59:59.000
G: The problem is that we switched the[br]phone system a while ago last year at the
9:59:59.000,9:59:59.000
Congress. And the old phone system had a[br]way how we can do the translation via one
9:59:59.000,9:59:59.000
channel and the problem is that the new[br]system doesn't support this. Let me say
9:59:59.000,9:59:59.000
the new system doesn't support it yet. So[br]have a look at our talk and then you can
9:59:59.000,9:59:59.000
see that there is some potential.[br]H: I see someone at microphone number 3,
9:59:59.000,9:59:59.000
please. This would be the last question[br]because we have to hurry a bit.
9:59:59.000,9:59:59.000
Q: Can I know a little bit more about the[br]super charging microwave? I'm confused.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
M: Sure, you can come to our POC desk and[br]then we answer all your questions.
9:59:59.000,9:59:59.000
H: Ooh... mystery. Please, give the POC a[br]hand.
9:59:59.000,9:59:59.000
So next team, is it from the GSM crew?[br]Someone there? I think we have two. I see
9:59:59.000,9:59:59.000
some Chaos Post, you have to wait one[br]round. So, GSM guy thank you. I am good
9:59:59.000,9:59:59.000
with computers, I think. Yeah, I am. Have[br]fun. If it's working or not. Look at this
9:59:59.000,9:59:59.000
smile then looks better. Try this. Yeah.[br]Right. Try this.
9:59:59.000,9:59:59.000
- 423.[br]- Maybe you have to use GSM.
9:59:59.000,9:59:59.000
- 23 test.[br]- What happened?
9:59:59.000,9:59:59.000
- Hello. Hello.[br]- Aah.
9:59:59.000,9:59:59.000
GSM Person 1: So as every year we ran our[br]own mobile phone network at the Congress
9:59:59.000,9:59:59.000
using osmocom open source software for 2G[br]and 3G, and open5gs interfacing with the
9:59:59.000,9:59:59.000
osmocom HLR. And all you need to take part[br]is a SIM card that you can buy from the
9:59:59.000,9:59:59.000
POC and for 5 euros you get a flat rate.[br]The price increases because we have less
9:59:59.000,9:59:59.000
SIM cards every year. We need to[br]manufacture new ones. You can even call
9:59:59.000,9:59:59.000
outside like you can with DECT phones.[br]Lynxis: Hello. I'm Lynxis. So as every
9:59:59.000,9:59:59.000
year for the GSM team, the first problem[br]is the license. That's the first step
9:59:59.000,9:59:59.000
usually. Because in Germany, you have to[br]get the official form, get a license but
9:59:59.000,9:59:59.000
... Where do you get it? What can you ask[br]for frequencies? Because, for example, the
9:59:59.000,9:59:59.000
POC for DECT or Wi-Fi, you just place it[br]and you can use it. You're fine.
9:59:59.000,9:59:59.000
But for GSM, they didn't think about it or[br]for 3G or 4G. So yeah, this year we
9:59:59.000,9:59:59.000
usually get the license middle of[br]december, maybe start of december. So it's
9:59:59.000,9:59:59.000
already late. So this year we didn't get[br]all our licenses. But we get some. We got
9:59:59.000,9:59:59.000
850 MHz, which is not assigned in Europe[br]because it's usually in the US only. But
9:59:59.000,9:59:59.000
we have a small hole. This year we got a[br]4G license instead of a 2G license with 10
9:59:59.000,9:59:59.000
Mhz from Telefonica. So thanks Telefonica[br]for borrowing us spectrum.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
L: Just a short example of how the[br]spectrum looks like. The yellow stuff is
9:59:59.000,9:59:59.000
usually somewhere behind actually. By the[br]way, this microphone, it might share the
9:59:59.000,9:59:59.000
same frequency with us. But so far, we[br]haven't found any interference together
9:59:59.000,9:59:59.000
with the VOC. Down there you can see the[br]small hole which we are using. Because we
9:59:59.000,9:59:59.000
didn't get the 2G license there, we[br]thought, OK. Let's take a look. Can we fit
9:59:59.000,9:59:59.000
them both in the same frequencies? It's[br]not good. But you see the spikes, this
9:59:59.000,9:59:59.000
nice antenna on the right. That's the GSM,[br]which is sending on the same frequency. It
9:59:59.000,9:59:59.000
works because they are using different[br]codings. But I have heard from people who
9:59:59.000,9:59:59.000
know more about it, this is not the way[br]you use it.
9:59:59.000,9:59:59.000
laughing[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
L: So we took some photos of our base[br]stations. This is actually the fairy dust
9:59:59.000,9:59:59.000
from the 2G base station, so we have a[br]idea what we are using here. We have even
9:59:59.000,9:59:59.000
more fairy dust in our 3G femtocells and[br]our 4G cells. They are looking like small
9:59:59.000,9:59:59.000
toasters. They are taking actually 90[br]watts via POE, they have special POE
9:59:59.000,9:59:59.000
adapters. So maybe we could ask if[br]somebody can do a similar adapter to get
9:59:59.000,9:59:59.000
even running a toaster on the line.[br]So basically for the 4G setup this year,
9:59:59.000,9:59:59.000
we weren't sure if it's stable enough or[br]we lose all our phones to the LTE and they
9:59:59.000,9:59:59.000
don't like to come back to the 2G and 3G[br]setup where we have voice, because on LTE
9:59:59.000,9:59:59.000
we don't have yet voice so you have to[br]select specifically to join the LTE
9:59:59.000,9:59:59.000
network. That worked quite fine if you[br]change it. So your phone will register.
9:59:59.000,9:59:59.000
Everything fine there.[br]GSM1: So the rollout this year: we had the
9:59:59.000,9:59:59.000
voice working on day 0 which is new.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
GSM1: Someone even noticed on Mastodon, I[br]saw it, too. We already had LTE at the CCC
9:59:59.000,9:59:59.000
camp this year. Yeah, but unfortunately we[br]lost crypto password, so LTE roll out took
9:59:59.000,9:59:59.000
a bit longer this time. Sorry. So some[br]numbers. In total we saw just about 1100
9:59:59.000,9:59:59.000
people doing a location updating on our[br]network and 845 eventphone tokens were
9:59:59.000,9:59:59.000
dialed on the GSM. That is 2G or 3G. And[br]there were roughly 200 phones actively
9:59:59.000,9:59:59.000
subscribed on the network at all times.[br]And even though we basically only deployed
9:59:59.000,9:59:59.000
3G nano stations in all the halls and only[br]had two 2G BTS in the glass halle, there
9:59:59.000,9:59:59.000
were roughly more than half of all the[br]phones were still subscribed on 2G instead
9:59:59.000,9:59:59.000
of 3G. We had like 18 3G stations and only[br]two plus one in the GSM room 2G stations.
9:59:59.000,9:59:59.000
So that's a bit surprising. And SIM cards:[br]starting from the bottom, we sold about
9:59:59.000,9:59:59.000
700 SIM cards, but only saw half of them[br]activated, which is curious. And luckily,
9:59:59.000,9:59:59.000
most or some people bring old SIM cards[br]from previous years. And it's not so easy
9:59:59.000,9:59:59.000
to get cards manufactured. So we are very[br]glad for everyone who brings old SIM cards
9:59:59.000,9:59:59.000
from previous events. We might even[br]consider introducing charging phone calls
9:59:59.000,9:59:59.000
only for SIM cards that are newly bought.[br]So if you want to continue calling for
9:59:59.000,9:59:59.000
free, rather bring your old SIM cards.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
GSM1: So you see the numbers, I'm not[br]going to go through them. And you can also
9:59:59.000,9:59:59.000
get the ADM, the admin keys for your SIM[br]cards if you like to write to them.
9:59:59.000,9:59:59.000
L: Or if you have seen the talk from[br]LaForge, you might want to play with the
9:59:59.000,9:59:59.000
SIM cards, we give out all the keys you[br]want to have to play with it.
9:59:59.000,9:59:59.000
GSM1: So operation was mostly smooth,[br]except iPhones, for unknown reasons. And
9:59:59.000,9:59:59.000
except the data service, which might even[br]be related because maybe Apple is a bit
9:59:59.000,9:59:59.000
more strict on whether data service is[br]working reliably. Yeah, we still had some
9:59:59.000,9:59:59.000
problems in the SGs instance introducing[br]3G changing between the radio access
9:59:59.000,9:59:59.000
technologies. It's a whole new ballgame so[br]there are still some bugs in there. And as
9:59:59.000,9:59:59.000
you see, we had many more tickets than the[br]POC. This is actually reversed from the
9:59:59.000,9:59:59.000
POC, the "done" is on the left. So this[br]whole bunch of stuff is done and there's
9:59:59.000,9:59:59.000
some backlog and canceled and fantasy[br]tasks. It worked pretty nicely. Are you
9:59:59.000,9:59:59.000
taking over? Oh, yeah, no, this is still[br]mine. And this year we actually had also a
9:59:59.000,9:59:59.000
denial of service attack. The code was the[br]same as previous years and we never saw
9:59:59.000,9:59:59.000
this before. But this year we got an[br]invalid mobile identity which managed to
9:59:59.000,9:59:59.000
crash our mobile switching center. And[br]thank you very much for uncovering this
9:59:59.000,9:59:59.000
bug and thanks to fixeria for fixing it on[br]day 2. Ever since the mobile switching
9:59:59.000,9:59:59.000
center for Voice and SMS and subscription[br]has been running stable.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
L: Maybe some interference. We recovered[br]the old phones again. Last year we
9:59:59.000,9:59:59.000
couldn't support them. But we managed to[br]implement the missing parts. Old phones
9:59:59.000,9:59:59.000
could work if they support the[br]frequencies. So that's really nice. Maybe
9:59:59.000,9:59:59.000
next time. Since camp, we also did a nice[br]angel helpdesk. And it was really
9:59:59.000,9:59:59.000
impressive to see that we even had to add[br]more shifts in our shifts. We had so many
9:59:59.000,9:59:59.000
motivated angels. Thanks to everybody who[br]helped us, it was really great.

have working microphones.[br]Chaos post 1: Sorry, we need to interrupt
9:59:59.000,9:59:59.000
you anyway.[br]H: OK. So tell them, chaos post! Chaos

9:59:59.000,9:59:59.000
H: Let's get rid of the broken one because[br]it's not working anyway.
9:59:59.000,9:59:59.000
Chaos post 1: All right. Sorry, we are[br]interrupting for a few minutes only. We
9:59:59.000,9:59:59.000
would like to deliver a few statistics as[br]well. So thanks of all, we had multiple
9:59:59.000,9:59:59.000
chaos deliverers working throughout the[br]whole Congress 24/7 basically, delivering
9:59:59.000,9:59:59.000
at the speed of chaos, as our mission[br]statement clearly states. So thank you
9:59:59.000,9:59:59.000
therefore, first of all thank you very[br]much to all of you who contributed to
9:59:59.000,9:59:59.000
that.[br][Filler, please remove me in amara]

Chaos post 2: So let's have some numbers,[br]because you all love numbers, right? So we
9:59:59.000,9:59:59.000
delivered about 3000 external postcards.[br]So that means with like outside chaos, so
9:59:59.000,9:59:59.000
to the real world or the default world, as[br]we call it. We delivered those to over 42
9:59:59.000,9:59:59.000
countries all over the world. So you guys[br]are really good connected internationally.
9:59:59.000,9:59:59.000
And also, we don't have exact numbers, but[br]we estimate around 3500, no, 35000,
9:59:59.000,9:59:59.000
internal postcards. And you also use our[br]online office for a total of 789 times. So
9:59:59.000,9:59:59.000
that is only 15 less than camp, and that[br]was a longer event. So, hey, you guys
9:59:59.000,9:59:59.000
write a lot of postcards![br][Filler, please remove me in amara]

Chaos post 1: As you might already know[br]from camp, we also do have a few special
9:59:59.000,9:59:59.000
services. As already on camp, we had the[br]serving proposal, basically a pre-
9:59:59.000,9:59:59.000
assembled text, you just had to cross what[br]you want. The postbox certification and of
9:59:59.000,9:59:59.000
course, the bi-directional chaos, in[br]Germany also known as "Einschreiben mit
9:59:59.000,9:59:59.000
Rückschein".[br]H: Wow.
9:59:59.000,9:59:59.000
Chaos post 2: And this time we also[br]offered some new services. We had like
9:59:59.000,9:59:59.000
sang telegrams, gesunges Telegram in[br]Deutsch. We had a forever alone box for
9:59:59.000,9:59:59.000
people wanting to write postcards with or[br]exchange postcards with no idea who to
9:59:59.000,9:59:59.000
write it to. We had love letters, so we[br]had some nice pre-assembled texts and also
9:59:59.000,9:59:59.000
a really nice selection of perfumes for[br]scented postcards. You could write some
9:59:59.000,9:59:59.000
secret messages. We had some UV pens and[br]also we had some, let's say call it
9:59:59.000,9:59:59.000
security, or rather temper evidence,[br]because we had some scratch off stickers
9:59:59.000,9:59:59.000
for you. And also we had over 30 new[br]postcard designs that you could use for
9:59:59.000,9:59:59.000
postcards.[br][Filler, please remove me in amara]

9:59:59.000,9:59:59.000
Chaos post 1: Short remark for the love[br]letters and the perfumes. Well, that was
9:59:59.000,9:59:59.000
kind of not really thought through. It was[br]a bit... it was fun sorting them out, and
9:59:59.000,9:59:59.000
stamping all of that, smelling all the[br]perfume all the time.
9:59:59.000,9:59:59.000
Chaos post 2: And then brushing your hands[br]really thoroughly because, well, that
9:59:59.000,9:59:59.000
stuff gets on your hands when you do that.[br]Chaos post 1: Also for UV pens. Just a
9:59:59.000,9:59:59.000
little remark. It's not a good idea to use[br]it for addressing and the message.
9:59:59.000,9:59:59.000

9:59:59.000,9:59:59.000
Chaos post 1: You can take the risk. All[br]right, then let me close up. We also
9:59:59.000,9:59:59.000
supported mail this year and[br]we had 130 letters for activists in
9:59:59.000,9:59:59.000
prison, which I find really great. I think[br]that's something we can all support.
9:59:59.000,9:59:59.000
Amazing.[br][Filler, please remove me in amara]

applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
So thank you all for this amazing event,[br]and have some fun for the rest of the
9:59:59.000,9:59:59.000
Congress.[br][Filler, please remove me in amara]

H: Chaos post! So the next team is the[br]VOC. Yes, you can have it. Here, the VOC.
9:59:59.000,9:59:59.000
We only have 20 minutes left in total for[br]every team. So you know what to do.
9:59:59.000,9:59:59.000
VOC1: Hurry up. Welcome, guys. So. Yeah.[br]We don't have as many statistics as usual.
9:59:59.000,9:59:59.000
But we have some great stories too. We'll[br]hurry up. So this year in total, we
9:59:59.000,9:59:59.000
covered 10 stages apart from the 5 stages[br]that we do usually for Congress. We had
9:59:59.000,9:59:59.000
streams from the critical decentralisation[br]cluster, Sendezentrum, Wikipaka WG, Open
9:59:59.000,9:59:59.000
Infrastructure Orbit, Chaos West. And in[br]total, we served 255 hours and 35 minutes
9:59:59.000,9:59:59.000
of total talk time. So you know what to do[br]until the next Congress.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
VOC1: And of course, sustainability was a[br]big topic during this Congress. So part of
9:59:59.000,9:59:59.000
what we have to do is stream reencoding so[br]you can watch it with the VP5 codec or use
9:59:59.000,9:59:59.000
it at lower resolution. And so far we've[br]been using 4 Xeon-based machines and 2
9:59:59.000,9:59:59.000
desktop machines. And thanks to hardware-[br]based encoding, we now replace this with a
9:59:59.000,9:59:59.000
single laptop. As you can maybe read, this[br]is critical infrastructure now. And for
9:59:59.000,9:59:59.000
all the streams, for 30 reencoding[br]streams, we are on a 45 watt power budget
9:59:59.000,9:59:59.000
now. And as an added benefit, because we[br]also encode the master slides with
9:59:59.000,9:59:59.000
hardware encoders, and hardware encoders[br]can generally use a higher profile that
9:59:59.000,9:59:59.000
allows for better quality in real time,[br]you now get a better picture as well. So,
9:59:59.000,9:59:59.000
yeah.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
VOC1: And of course, we had some minor[br]fuckups this year. We thought the audio
9:59:59.000,9:59:59.000
setup was a bit less complex. But when we[br]checked rooms, we had buzzing everywhere.
9:59:59.000,9:59:59.000
So we replaced some SDI lines with fiber[br]and turns out buzzing goes away. Then the
9:59:59.000,9:59:59.000
PA sound console had a buggy DANTE card.[br]After you reboot them, the auxiliary out
9:59:59.000,9:59:59.000
to the VOC cameras was muted. So that[br]messed up the particular talk that has
9:59:59.000,9:59:59.000
been redone today, but other than that, we[br]are rather happy. And we figured that 3 of
9:59:59.000,9:59:59.000
our audio mixers actually had broken[br]outputs. I don't know how we did that, but
9:59:59.000,9:59:59.000
it clearly shows that they've been used on[br]one event or another during the last
9:59:59.000,9:59:59.000
years, which is actually a good thing we[br]may think. On the Wikipaka stage, we did
9:59:59.000,9:59:59.000
not use Ansible because there was sort of[br]a playground for us. But if you don't do
9:59:59.000,9:59:59.000
things properly, well, then you run into[br]edge cases with things. And yeah. So I
9:59:59.000,9:59:59.000
need to hurry up. And one virtualization[br]host suddenly started leaking memory. And
9:59:59.000,9:59:59.000
so if you were affected by that during the[br]main talk season in the evening, we are
9:59:59.000,9:59:59.000
very sorry about that. Updating the kernel[br]helped and we have no idea what happened.
9:59:59.000,9:59:59.000
Yeah, and Icecast got stuck as well. And[br]some relive... so if you want to see talks
9:59:59.000,9:59:59.000
later, that may not be possible because we[br]ran temporarily out of space. But if you
9:59:59.000,9:59:59.000
watch this on media.ccc.de, and the talks[br]were not yet released, we have relive
9:59:59.000,9:59:59.000
integration, so the talks show up in[br]media.ccc.de even though there is no
9:59:59.000,9:59:59.000
proper release yet, for your convenience.[br]And main track and assemblies are now
9:59:59.000,9:59:59.000
integrated in all events, so you don't[br]have to click through 4 separate events to
9:59:59.000,9:59:59.000
find your favorite talk. And now I pass to[br]Pat to talk about VOCTOMIX 2.
9:59:59.000,9:59:59.000
Pat: Yeah. Thank you. Okay. I have now 20[br]seconds, I think. I made a redesign of
9:59:59.000,9:59:59.000
VOCTOMIX, it's now called VOC2MIX. And[br]Peter was doing that meme some weeks ago,
9:59:59.000,9:59:59.000
because we had to switch to VOCTOMIX 2 and[br]we wanted to try it in 2 rooms. And in the
9:59:59.000,9:59:59.000
night from day 0 to 1 we decided to do it[br]for every stage because the old solution
9:59:59.000,9:59:59.000
was not working anymore. That was a little[br]bit hot, but it worked. And, the redesign
9:59:59.000,9:59:59.000
caused the new UI, complete with some new[br]base features. We have now transitions
9:59:59.000,9:59:59.000
where pictures are moving, and we have[br]insertions for blending text into the
9:59:59.000,9:59:59.000
picture and we have a new audio mixing and[br]we are now proper A/V Sync in every case,
9:59:59.000,9:59:59.000
I think.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
Pat: And some mixer angels were exploring[br]the software and they found some bonus
9:59:59.000,9:59:59.000
features like random video distortion in[br]some cases, which I have to fix, I think.
9:59:59.000,9:59:59.000
And the party mode where you click some[br]buttons and they are clicking without any
9:59:59.000,9:59:59.000
doing of the user and everything is[br]flickering and they called it party mode.
9:59:59.000,9:59:59.000
This is what the current pipeline looks[br]like. We have now over 200 gstreamer
9:59:59.000,9:59:59.000
elements doing all this stuff to get your[br]pictures, which you are having on the
9:59:59.000,9:59:59.000
stream and in the recordings. That's it.[br]VOC1: So, of course, there were some
9:59:59.000,9:59:59.000
issues. I mean VOCTOMIX2 is essentially a[br]rewrite.
9:59:59.000,9:59:59.000
H: You have to speed up a bit. Actually we[br]are stealing time from the other teams. I
9:59:59.000,9:59:59.000
might call it a quit.[br]VOC1: OK OK OK. So...
9:59:59.000,9:59:59.000
H: Pressure![br]VOC1: Yes, I know. But you're not making
9:59:59.000,9:59:59.000
things better. So one thing to mention: we[br]had to deploy a sweaty finger fix after
9:59:59.000,9:59:59.000
the first talk started. Ok, here are your[br]stats, read them now, read them read them
9:59:59.000,9:59:59.000
read them![br][Filler, please remove me in amara]

9:59:59.000,9:59:59.000
H: Please give VOC a hand. Thank you. So[br]what's next? Oh, the Stage manager and
9:59:59.000,9:59:59.000
Herald Operation Center. I'm part of it.[br]And we have 36 heralds, every one of them
9:59:59.000,9:59:59.000
very eloquent and good-looking. Then we[br]have 70 stage managers and stage
9:59:59.000,9:59:59.000
supporters. We had 150 shows on official[br]stages and the assemblies on top of it. We
9:59:59.000,9:59:59.000
have one stage fright council yet for the[br]speakers who took care of at least six
9:59:59.000,9:59:59.000
talks. And then we threw away over 100[br]hosting cards on day 1 only. So clearly,
9:59:59.000,9:59:59.000
give a hand for the SHOC.[br][Filler, please remove me in amara]

H: So next, c3power. Your time.[br]Arif: So my name is Arif Guy. I am from
9:59:59.000,9:59:59.000
the power team and from the radio[br]operation center. We make the power. We
9:59:59.000,9:59:59.000
load five double trucks of shit out on[br]Sunday 15th. We deploy a lot of power
9:59:59.000,9:59:59.000
boxes and many cables. So we have teardown[br]today so every help is needed. We have
9:59:59.000,9:59:59.000
only one day to bring us back. The main[br]thing, we had the power meter that we made
9:59:59.000,9:59:59.000
on the camp this year. We have two nice[br]setup on room H. You see the power factor
9:59:59.000,9:59:59.000
is very bad. And the other one was the[br]Waffle Operation Center so you see they
9:59:59.000,9:59:59.000
have a nice power factor. So please use[br]more ohmic devices like heaters, waffle
9:59:59.000,9:59:59.000
iron or something. We only have 5 Seaview[br]to monitor Yolocolo. You have on
9:59:59.000,9:59:59.000
c3power.top a Grafana link that also links[br]to the main Grafana to the NOC. Another
9:59:59.000,9:59:59.000
nice thing we have on the lounge, I have a[br]video here. It started now. You can see
9:59:59.000,9:59:59.000
the current on all 3 phases to the audio[br]and you can see the audio from the lounge.
9:59:59.000,9:59:59.000

Arif: Use more bass, or make more current.[br]Later we can show you another slide. Go to
9:59:59.000,9:59:59.000
next slide please. So for the radio team[br]we have 120 portable radios. We have
9:59:59.000,9:59:59.000
updated them to a new firmware, and a new[br]programming software with a new feature
9:59:59.000,9:59:59.000
that is a lot slower than the last[br]version. Very nice. 50 bring-your-own-
9:59:59.000,9:59:59.000
device radios. 5 dead radios from the[br]camp. 2 dead from 36c3. 2 dead repeaters
9:59:59.000,9:59:59.000
from the camp. 1 dead on arrival on this[br]stage. 3 rental repeaters from 2
9:59:59.000,9:59:59.000
companies, one we picked up in Hannover[br]just before the Congress, and even the
9:59:59.000,9:59:59.000
windows PC crashed down dead on arrival.[br]Business as usual. So, next team!
9:59:59.000,9:59:59.000
H: Thank you! So, the next is c3subtitles.[br]I think it's Amy and Julia. Amy. They are
9:59:59.000,9:59:59.000
not. C3SOS. S.O.S. It's you. Okay. Okay.[br]Sorry. Oh, I'm sorry. Not the subtitles.
9:59:59.000,9:59:59.000
It's well, sustainability. Your stage, go[br]for it. Here, feel free.
9:59:59.000,9:59:59.000
Amy: Hello. Okay, hi. My name is Amy, I'm[br]part of the c3sustainability team. I only
9:59:59.000,9:59:59.000
have four slides, so I'll be very quick.[br]You can see, the first of our biggest
9:59:59.000,9:59:59.000
projects was the drinking water[br]dispensers. So for angels, we had drinking
9:59:59.000,9:59:59.000
water from a dispenser rather than from[br]bottles and they could refill their
9:59:59.000,9:59:59.000
bottles. We go through some stats there.[br]So when we started planning how difficult
9:59:59.000,9:59:59.000
it was to implement it, the locations, and[br]how many volunteers, satisfaction was very
9:59:59.000,9:59:59.000
high for this one. So thank you to c3geld[br]who really helped organize the water
9:59:59.000,9:59:59.000
dispensers with us. We're very happy. They[br]were really great. Please give them a
9:59:59.000,9:59:59.000
round of applause.[br][Filler, please remove me in amara]

applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
Amy: Thank you. The next one was a give[br]and take electronic box. So we wanted to
9:59:59.000,9:59:59.000
encourage people not to throw away their[br]electronics. Of course, they can be
9:59:59.000,9:59:59.000
recycled. So we have deployed 10 boxes.[br]You can find them in the sticker stations.
9:59:59.000,9:59:59.000
And we did this in collaboration with the[br]hardware hacking area. Thank you. And
9:59:59.000,9:59:59.000
other assemblies. Oh, wow, you are really[br]fast.
9:59:59.000,9:59:59.000
H: Yes I am.[br]Amy: Okay!
9:59:59.000,9:59:59.000
H: Others are waiting![br]Amy: Okay. So the last one I wanted to go
9:59:59.000,9:59:59.000
through. We have two initiatives on this[br]one. I'm sorry for the trashy picture
9:59:59.000,9:59:59.000
there. We have organic bins in the halls.[br]It was very, very difficult to do this.
9:59:59.000,9:59:59.000
But actually it was quite satisfactory.[br]But I would say there is room for
9:59:59.000,9:59:59.000
improvement there. And there was also an[br]initiative for recycling cigaret butts. So
9:59:59.000,9:59:59.000
we actually had two people go round,[br]collect your cigaret butts and they will
9:59:59.000,9:59:59.000
be recycled into cool ashtrays. What a[br]success! Thank you so much to everyone who
9:59:59.000,9:59:59.000
collaborated with us. We couldn't do out[br]without your help.
9:59:59.000,9:59:59.000
H: Thank you. Your applause, please.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: So unfortunately, the c3sign is not[br]coming. So just take a look at those
9:59:59.000,9:59:59.000
pictures while I go through them. And now[br]the next one is C3 Assemblies. Here, take
9:59:59.000,9:59:59.000
this one. Thank you. Be quick.[br]Pingu: Hi, my name is Pingu. I'm here for
9:59:59.000,9:59:59.000
the assembly team. And I just want to ask,[br]give a hand who hasn't found his assembly
9:59:59.000,9:59:59.000
on day zero or day one? So then give a big[br]applause to c3nav because they really
9:59:59.000,9:59:59.000
helped us a lot. Because without them, it[br]wasn't able to do this event just for us.
9:59:59.000,9:59:59.000
Because for some figures we had 419[br]assemblies to place on this area which is
9:59:59.000,9:59:59.000
about 35000 square meters. We had 3000[br]tables all over, 2500 in the assemblies,
9:59:59.000,9:59:59.000
with 6000 chairs. And here, please give a[br]big applause to the C3Möbelhaus or IKEA as
9:59:59.000,9:59:59.000
you call it.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
Pingu: Because the Möbelhaus basically[br]placed all the tables in a magic night on
9:59:59.000,9:59:59.000
basically day -2. And they will disappear[br]with the help of C3Möbelhaus today. We
9:59:59.000,9:59:59.000
assigned the last assembly on day zero at[br]22:00 and we started our work in mid-
9:59:59.000,9:59:59.000
October with weekly meetings. And yeah, as[br]you can see, it was a lot of work and...
9:59:59.000,9:59:59.000
Oh.[br]H: Thank you.
9:59:59.000,9:59:59.000
Pingu: Thank you. And just one thing, for[br]teardown, for tearing down the assemblies,
9:59:59.000,9:59:59.000
please stack the chairs on the assembly[br]but leave every chair and every table on
9:59:59.000,9:59:59.000
the assembly, we will get rid of them.[br]H: Thanks a lot. Your applause. So the
9:59:59.000,9:59:59.000
next ones are... Les prochains, ce sont[br]les gens de c3lingo, voilà, vos tours!
9:59:59.000,9:59:59.000
c3lingo 1: Hallo! Schön euch mal (...) Wir[br]sind übersetzet. (...)
9:59:59.000,9:59:59.000
German>[br]Oh, sorry. Well, I'm also fine with that.
9:59:59.000,9:59:59.000
We translated all the German talks into[br]English. All the English talks into
9:59:59.000,9:59:59.000
German. All in all, fifteen thousand[br]minutes in seven different target
9:59:59.000,9:59:59.000
languages. And here is from the second[br]language team, who talk all the non-
9:59:59.000,9:59:59.000
English and non-German things.[br]c3lingo 2: Okay. So basically we did have
9:59:59.000,9:59:59.000
about 1/3 of the talks were translated to[br]French. Yeah. You can read the rest. And
9:59:59.000,9:59:59.000
we even have currently, exactly, right[br]now, another one which is translated into
9:59:59.000,9:59:59.000
Swabian. So if you want to listen into it.[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
c3lingo 2: Which means that if you were[br]listening to a talk, there is 2 chance out
9:59:59.000,9:59:59.000
of 3 that it was translated not only once,[br]but twice. Into either French, Spanish,
9:59:59.000,9:59:59.000
Russian, or Polish. One special mention[br]for the Russian and Polish teams, that was
9:59:59.000,9:59:59.000
their first time this year. So one big[br]round of applause for them, please.
9:59:59.000,9:59:59.000
applause[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
c3lingo 2: And one more big thank about[br]for the guys who brought the cough candies
9:59:59.000,9:59:59.000
and cough drops in the booth. That's a[br]lifesaver. Thanks.
9:59:59.000,9:59:59.000
H: Thank you. Merci beaucoup. So we have[br]some heart operation going on here. You
9:59:59.000,9:59:59.000
have to switch it or not? Oh, you're good[br]with computers.
9:59:59.000,9:59:59.000
laughing[br][Filler, please remove me in amara]
9:59:59.000,9:59:59.000
H: He just mimicks something. So[br]c3infrastructure from the subtitles. Your
9:59:59.000,9:59:59.000
stage. Yeah. My microphone. Ha ha.[br]td: So, thanks. Just a quick look into the
9:59:59.000,9:59:59.000
subtitles. So what do we actually do when[br]we subtitle a talk? Well, first of all, we
9:59:59.000,9:59:59.000
take the video from the C3VOC and put it[br]through speech recognition just to get a
9:59:59.000,9:59:59.000
rough transcript that we can then give to[br]angels to actually correct, because, well,
9:59:59.000,9:59:59.000
machine speech recognition doesn't work so[br]good at all. And then once we have a
9:59:59.000,9:59:59.000
working transcript that humans have looked[br]at, we put that through auto-timing, which
9:59:59.000,9:59:59.000
just takes the transcript and aligns that[br]with the audio, and that usually works
9:59:59.000,9:59:59.000
pretty well. And, well, once that is[br]finished, then we actually have working
9:59:59.000,9:59:59.000
subtitles, but we give them to angels for[br]another round of review just to fix any
9:59:59.000,9:59:59.000
mistakes that got overlooked. And maybe[br]sometimes the timing needs to be adjusted.
9:59:59.000,9:59:59.000
And then, when that is done, well, the[br]subtitle is released. And actually one of
9:59:59.000,9:59:59.000
our angels did a nice chart about all this[br]process that you can see here. It all
9:59:59.000,9:59:59.000
sounds better, so thank you for that.[br]Well, no presentation without graphs. As
9:59:59.000,9:59:59.000
you can see, the important thing is[br]really: everything goes up and to the
9:59:59.000,9:59:59.000
right. On the bottom here we have finished[br]seconds of transcribed talks. So this is
9:59:59.000,9:59:59.000
really completed subtitles here. And it[br]starts already quite high because it
9:59:59.000,9:59:59.000
includes all the Congresses before. Then[br]we have stuff that has been reviewed in
9:59:59.000,9:59:59.000
orange. Stuff that has been timed but not[br]reviewed yet in yellow. And transcribed
9:59:59.000,9:59:59.000
but not yet timed stuff in green. All in[br]all, we had 144 distinct angels. Yeah, I
9:59:59.000,9:59:59.000
need to hurry up. 71% of which took 2[br]shifts and 10% took 7 or more shifts. So
9:59:59.000,9:59:59.000
433 hours of work for 126 hours of[br]material. And so far we've had 6 releases
9:59:59.000,9:59:59.000
from this Congress and then lots of hours[br]worked. All of these numbers are at least
9:59:59.000,9:59:59.000
as high as last year's numbers, so good,[br]thanks. When you have transcripts, you can
9:59:59.000,9:59:59.000
do cool stuff with that. So, for example,[br]generate word clouds to see what people
9:59:59.000,9:59:59.000
like. And this case, people seem to like[br]people and questions and time, which we
9:59:59.000,9:59:59.000
don't have any here. So. Well, how do we[br]actually keep track of all this
9:59:59.000,9:59:59.000
complicated stuff? Well, we use a state-[br]of-the-art NoSQL lock-free columnar data
9:59:59.000,9:59:59.000
store, like many of the other teams also[br]do. And well, thank you all of our angels
9:59:59.000,9:59:59.000
for your hard work. And also thanks for[br]the Heaven for supporting us. And then,
9:59:59.000,9:59:59.000
well, if you if you feel bored between[br]Congresses, you can still continue to work
9:59:59.000,9:59:59.000
on transcripts. You have all the[br]informations here, these slides will be
9:59:59.000,9:59:59.000
online, follow us on Twitter. And thank[br]you.

9:59:59.000,9:59:59.000
H: So this was the last one. I think I[br]will try my best to do something like this
9:59:59.000,9:59:59.000
too. Actually I'm not good with computers,[br]but I know someone who is and who takes
9:59:59.000,9:59:59.000
very great care of everyone of us. So one[br]of my highlights of every Congress, feel
9:59:59.000,9:59:59.000
free, the LOC![br]LOC: Hello. I'm the stand-in for LOC. As
9:59:59.000,9:59:59.000
with all good projects, they're too busy[br]for documentation. They're packing. So LOC
9:59:59.000,9:59:59.000
doesn't have anything. I'm more of the[br]Department of Health and Safety again. So
9:59:59.000,9:59:59.000
for everyone: we have the message from[br]CERT that there were no work-related
9:59:59.000,9:59:59.000
accidents that caused real harm. The odd[br]broken Mate bottle maybe. But thank you
9:59:59.000,9:59:59.000
for having built a city again safely and[br]orderly, even with all the chaos. For the
9:59:59.000,9:59:59.000
people who are driving, please make sure[br]that the drugs wear off and that you get
9:59:59.000,9:59:59.000
some sleep and for all people riding[br]along, please keep the guys awake. That
9:59:59.000,9:59:59.000
would be greatly appreciated. Go home[br]safely. Thank you very much.

9:59:59.000,9:59:59.000
H: So. Wow, ah, OK. So I'm very sorry to[br]have to rush some teams and I'm very sorry
9:59:59.000,9:59:59.000
that we don't have any time left. We are 1[br]minute over and I promised the teardown
9:59:59.000,9:59:59.000
crew to not do overtime. So please, please[br]give all the teams their respect and clap
9:59:59.000,9:59:59.000
and tramp as loud as you can for now to[br]finish!
9:59:59.000,9:59:59.000

H: Everything! They did! For us! We did![br]For them! Why are you still sitting? You
9:59:59.000,9:59:59.000
have to leave. Thank you. From the[br]c3infrastructure Review. Goodbye.
