good hello everyone welcome to this
year's infrastructure radi I'm Nik du
from from the no with me as will we got
sent uh two slides which I will just
like present before from the nice dud
doing the um logo fix on the building so
you all saw the CCC logo he's doing that
since a couple of years now and uh it's
3 m in diameter and 25 kg heavy the
thing um the goggly eyes above the door
were the leftover parts of the sea and
were properly recycled and you maybe saw
that little Lounge in the entrance uh
with the hammock and some nice flags on
the ball he really tried to get that
opened and approved but someone who
shall not be named deemed it unsafe to
have public access to that area so it
was a nice art installation but not that
usable maybe next year we will
see now we'll be head at the
knock um this year's network was had
kind of some challenges we had a new
building parts of the team changed as
always um parts of the infrastructure
themselves changed they renovated the
building with multim mode fibers uh
which made it pretty hard and we were
all exhausted from camp this year so it
was a late start late planning late
everything and we were like ah at least
our service were will be here on time
before everyone else arrived because at
the last events it was sometimes tricky
to get the hardware which will do all
the monitoring outo deployment up and
running we were like hey we will be here
on Tuesday and Wednesday the servers
will arrive on Monday on Tuesday that's
great he joked oh maybe they'll arrive
in Sig Park on somewhere else but they
arrived dead so yeah that that was kind
of a challenge uh we we handled that
packet corruption uh it caused minor
delays of like a day and some some more
gray hairs for the deployment but in the
end it worked out and that's all you had
Wi-Fi
um we know it
worked hi everyone um yeah as Nico
mentioned um when they refurbished the
building uh they they refurbished they
did replace all the comm's rooms which
is Ni nice uh we have a new shiny comms
locations that much easier to install
equipment and not as hot as previously
um but uh we had a lot of challenges
with the fibers they chose to use
between the com rooms um this this
diagram here is is is our Core diagram
for the for the routers um so we we um
we decided to do some tests um we we
basically use some some new standards of
Optics that can uh actually have a
chance of lighting uh these fibers at
100 gig because 100 Gig is what we need
it's the technology of choice for the
backbone um so um we basically are doing
everything out of spec here um most of
these Optics are rated to about 100 m on
uh this multim mode fiber um we uh we
tested 100 Gig lr1 which is like a 100
Gig um in a single stream single Lambda
um and these two new standards sr2 and
Sr 1.2 um and they are new standards for
just getting a little bit more out of
this old standard of fiber um actually
the the last set here have proved some
of the best uh in our tests they
actually really only arrived in uh Flex
Optics about two weeks ago so um uh it
was really quite last minute um it's uh
essentially what they're doing in there
is they they're actually doing forward
era correction on the actual optic
itself which is quite clever um so
essentially we're doing sums to make the
network run
better uh everyone lost some stats uh we
had four times 100 Gig external
connectivity with 35 gig Peak usage uh
we Peak just over 100,000 Wireless users
um eight routers mostly in the basement
180 switches and 244 access points uh
we'll be starting to pull all that in in
about an
hour it's going to be busy um we had a
bunch of people who gave us nice stuff
um I'm not going to read them all out
now um but um some of these uh Transit
providers or equipment that we simply
cannot rent or or anything else so uh
that's we're very grateful that they
were provided that for
us a big shout out to to n at work the
in the bottom row they delivered service
here in Hamburg to us to replace the
broken flight case within like call them
they were yeah come come over pick
something up that was great
thanks
[Applause]
and just some some stats on the yellow
col which is run by the knock have desk
knock the knock themselves uh mostly
like uh 1 gig Port but also some some 10
gig Copper 10 gig fiber 40 gig ports
around 11 kilowatt of power and over 100
ipv4 addresses used and most of the
people had problems with getting IPv6
neighbor Discovery covery configured
properly so that's might be a reason why
we had so low IPv6 usage uh on our
Network because most of the stuff in the
col was running on V
only can't change that now over to the
phone Operation
[Applause]
[Music]
Center hi I'm Gavin from event phone or
you know us probably better as the phone
Operation Center and we will present
today uh together with the GSM team and
luy will do this but I will start from
our part first um so we arrived on day
Manus 4 and we expected working
infrastructure and then we had a quick
chat with the knock and they told us
about the [ __ ] up um nonetheless we were
amazed everything was up and running
really quickly even though there were
problems so uh we expected working
infrastructure on day minus two and I
guess this kind of worked out uh very
nicely so you had first dech
connectivity on minus two still uh
growing but nonetheless um yeah so big
thanks to the knock I think this is not
very new we now have for multiple years
even for the congresses in liik we
already had this IP based deck system um
where we really rely on the knock for
connectivity so thanks a lot we really
love you
guys um the next thing that is really
kind of new thing is that we this year
together together with the GSM team did
the help desk on one place and U man all
of this together so there is now the
common phone help desk um to have a
better customer experience for people
using all kind of phones because we run
the deck system the Zip system and the
like the Mainframe teleph background but
the GSM people really um run the GSM
parts so the RF Parts um and we can now
like move people back and forth just by
like saying well go to the next person
on this desk um so seems like this is
now three angular
[Laughter]
ration um yeah so we also had some
challenges uh we thought well let's kick
out all of the spinning discs of our
servers and replace them with super
fancy ssds which are faster um turns out
well um they didn't work out quite well
and we had like postgress query times in
the order of like 20 to 30 seconds for
one query similar just single insert um
this didn't really work out so uh we had
really false busy states which caused a
lot of trouble um we kicked them out
replaced them thanks to people who uh
were really helpful uh giving us
replacement Hardware on during Christmas
just uh very quickly and without asking
thanks a lot guys um we had some
additional problems in our core uh that
caused some Deadlocks and maybe people
have noticed that there were some
problems with the de registration and
this had a few hiccups but uh thanks to
our amazing team this was really also
fixed on site and it's now working in in
a reliable manner for I guess two days
um and for us also this is the first
event in the new renovated uh CCH um
there were some changes to find
everything again to really do a massive
multi level uh in in terms of multistory
event uh with our system and we had one
big challenge also we had controll DS on
our system because someone said well
let's invent pixel flute via zip um this
then this looks like
[Music]
this so you can call some number to set
a pixel and this caused quite some calls
and well it stress tested the system and
it didn't 100% survive wife and we need
to look into it but thanks for this
great reality
check yeah just some few numbers we had
like 120 uh Orga loan Decks that we
handed out we deployed over 50 zip
phones uh we had over roughly over 50
decked antennas here in the building and
nine remotely via VPN in several
locations throughout Germany that were
then also live connected to the system
um and there is the new bline deck
service where you can register yourself
um have some nice message and get in
touch with uh new other people get to
know other nerds there is quite some
numbers that you can reach it it was in
the end 115 registered users we had like
eight matches connected and the biggest
problem was a lot of users are not
reachable so uh if you want to use it in
the future make sure you're available
otherwise you can't be matched or rather
your match can not be like transfer to
you um we had like in the end 7,000
configured over 7,600 configured
extensions uh 4,200 configured deck
phones and like
2,700 concurrent at this event here
which isn't kind which isn't really the
number the the maximum number that we
had in the end in liik but I guess this
was to be expected um but we expect from
the community that you make us break the
record next year so bring more decked
call more decked
phones and thanks a lot um there is the
in Vienna we had a talk about how the
telepone system works if you're inspired
if if you if you're interested and want
to know how it works and um there is the
internal plan to maybe present on the
next Easter heeg again but no
promises so then let's
[Applause]
continue
yeah as usual we uh also built up a GSM
network and this year only LTE
so um yeah we also tried to be quite
early here our team also changed a lot
um new people arrived other people left
uh yeah we arrived a little bit earlier
as a park as usually it quite works well
at least on day four um we managed to
get on Day Zero the first calls and
everything working yeah the 4G was a
little bit special as
usual um the biggest problem for us is
to get the frequencies for um to provide
such Network because everything is sold
out there aren't any free frequencies so
uh we got five Arin or five channels in
1800 which every phone supports uh this
was sponsored um further we got uh 4G um
frequencies which are in the small Niche
it's actually us band not used in in
Europe uh from the Bonet netagent tour
um also thanks to the DOA Telecom for
loaning us and they were quite quick and
and giving us the the Spectrum really
[Applause]
nice yeah this year we had uh seven uh
2G base stations 12 4G enote BS uh we
had one mcro cell which supports quite a
lot AR Power but we only were allowed to
I think less than 1% of its actually
supported
power so this is a usual common setup
you see here a 2G small cell and a 4G um
yeah fto cell um I think this was close
to the info
desk uh yeah here's some some stats
about around thousand active users um we
also had a couple of cellb casts and as
you see we also uh started tracking the
stability 2G was really quick really
nice this time uh quite stable we are
using the osmocom stack and yeah the 4G
we're still continue developing it's
open 5gs and yeah it's we're hoping to
get it to zero but yeah we're still
working on it it's also really nice to
test with so many
users yeah the quality so basically if
you just wanted to have voice calls you
could disable the 4G also in the Guru
from the Pok um you deselected and
should have had really stable voice
calls and really really slow 2G data I
think maybe a couple kilobits per second
and 4G we we had couple megabits you
could get and we also have a couple of
challenges for the next year and uh yeah
that was it thanks to all the Angels who
helped us at at our help desk and
building everything
up
[Applause]
[Music]
hello we are from C fre
power
hi nice to meet
you I'm etk and this is fos and as you
already told we are from C3 power um we
are responsible for the uh energy
Department if you like to um so for
electricity and stuff um we managed to
to arrange some kpis for you
um as many of you may know um our
department has much more Logistics to do
than many other departments here and um
so it's now on this uh and on on this
event we had uh 200 flight cases in
total with material uh that was uh
borrowed at three companies or four I
think U we have 17,500 M of shuko cable
uh in few and a few lengths that were um
used here in the building as well as 100
m uh C 16 amps U 550 M CE 32 amps and
500 m c 30 63 amps uh unfortunately no
CE 125 this year uh because the the
house changed a bit of the of the
installation here so we're not able we
were not able to use it here um we had
65 distribution boxes in total of um
many kinds um fos will say a bit a few
words about um the latest generation of
them uh later in this in our part here
and um we had a pretty cool team this
year we were enough people to load
balance uh in a in a very very nice
Manner and um so this resulted in a in a
um average power hotline waiting time of
nearly 0 seconds um so we were reachable
around around the clock and this uh
worked quite well this event so I want
to thank our team for
that broken is broking equipment is
something that we uh know from the most
events that we that we uh arrange um and
just distribute with power so it was in
this year we got a few broken cables uh
we um we have some of them here for you
those are
um yeah they were were a
bit let's let's just not talk about
it and uh we had a we had um a nice
visit from the local fire
department at 2:00 I don't know on on
which day and and um yeah uh it was a
faulty a faulty um faulty light um that
blew up in the middle of the night and
um yeah that caused smoke and the fire
department arrived yeah but nothing
special happened so your
part so thank you Dominic um today this
year we got some really nice distros
from nickland which is our our main
rental company it has like a 63 to four
times Harding connector which is really
nice to distribute and every Harding has
a six rcbos so um it's really good that
it it's
um yeah it's just really
good and it has ethernet Jacks and per
Outlet current metering which is quite
nice this is the box it has like fancy
displays and stuff and it even has like
a very nice webui where you can see
different things this is the YOLO col
which performed really bad at um getting
power so please use more power
maybe and uh somebody from our team uh
hacked together some go and uh blew that
into a influx Deb which really
burned so we had this nice graph at C
fre power. toop you can all visit
did yeah and tear down already started
at noon and we are heavily on it thank
you for our
[Applause]
[Music]
[Applause]
team
let's see if this work yeah we are from
c rock we are those people with video
and W cutson Comm known for this and
let's have a look at the number ring we
had as usual lot of viers in stream a
lot bit stream traffic 10 terab of
content during the
event 200,000 views on the talks 100
talks released by now that's nearly all
but some still missing due to Tech
difficulties and we we have about 500 G
of cash but still 10% 7% IO rate if
someone has ssds and wants to donate
them to us please come we really happy
to optimize this
issue great then we come to the not so
boring numbers um the average help Des
waiting time during business hours was
like only one ring and if there were
like people calling actually with de or
they were like in front of the desk it
was only two rings times so it was not
so long waiting time uh our business
hours at the help desk we basically from
9: to the other 5 so 9:00 a.m. to uh 5
a.m. in the morning so really long time
at a health desk and this year's pool of
angels was about 310 AV Angel so thank
you very much for all of them who helped
us on the cameras the a angel in general
so thanks for
[Applause]
that now now to not so borrowing facts
people like political Beauty and
trains a big shout out to all those
creation Angels standing at the doors
doing the talks in the H Hall one it was
really hot up there so thank you for
your work it was really great having you
there making this whole stuff
[Applause]
possible a big knew their P music was
not played or only played in Hall one it
was in every
and it's called meas meas by Fe of
ghosts so look it up if you want to have
it at home by making your
team then there was a strange case of uh
ASN audio that we discovered uh so many
talks showed there was a delays and that
were not part of the source material and
then we did a bit of investigation and
that showed that random bites in the
fuse F system appeared and it turned out
that the current APS um strangely profit
from utas and the funny thing is that
this box has been around our en coding
change for actually years and we never
discovered it so that's a new thing that
we discovered this
Congress now let's have a look at the
infrastructure at our lecture hall this
year we just used our own setup with no
external help and the only thing we get
was some cameras from some friends and
family this time we tried automatic
audio leveling for streamed audio it
didn't work as expected in the endend we
have just a simple manual leveling and
it turned out that the um VJ Port turned
out as as a simple micro HDMI port no
one expected we connected our VJ at that
equipment and was wondering because
nothing came out and it was result
that then there was INF structure that
was not in electure holds there's not M
on the slides here well maybe we could
have put a bit more in it but we didn't
well yeah so there was a new web player
that was measuring the streaming quality
in general and then this slide is not
supposed to look like this but um the
thing is that during the first day many
people were asking where they talks um
they waiting for the talks and we had a
bit of problems and releasing them
because we had to wait for the intros
and outros to cut them in um so that
took a while but in the end uh we
finally started like encoding the videos
around like in the afternoon of the day
one and in the evening of uh day one we
finally released the first talk so they
took a while this year but in the end
they're there
[Applause]
and and and now to famous INF beer we
had about 2,000 combinations of slight
of peration on the first day at day four
it were 300,000 combinations and there
was about over 250 submissions and we
had in one formal complainant from G
organization we managed to site without
involving Board of the pl so thank you
for
that
hi I'm CA I'm here for the for the
interpreters those are lovely folks over
in the back or in some rooms on the
side
than
thanks um I'm that's probably
broken I don't know if you want to
regenerate the slide anyway that was a
picture out of the booth so you see the
way we see the room um usually the back
of your
head and um yeah this year was uh
obviously full of challenges as was for
everybody um the the long Gap hit us
hard on the second language so what we
do is um we make it accessible we give
the speakers of voice in another
language that they don't speak in the
talk and especially make it available
for uh people who don't speak the
language that is given mostly important
for um non-english speakers and uh we
have a big group of French people for
example that help us out a lot in that
department um we have so we have two
teams sub teams we are the German
English team and we are the bonus other
or whatever we call them we we haven't
settled on the name but um they do
everything else so if you've ever heard
us uh do a Swiss translation for uh one
of the fun talks in the evening that's
the other team we have French we have
Spanish we have Chinese we have Arabic
whatever makes sense for the talk
usually um depending on the topic so and
our team shrunk quite a bit over the um
over the pandemic and the Gap that this
gave us we still managed to do
everything for German and English but
unfortunately the other team only had a
chance for about a third of it so um if
you feel up to it we'd love to have you
um we take anyone who's who feels good
about it and will'll help you um this
Swedish one is especially fun because we
picked up a a drunk nice person at a
bar and uh they helped us
[Applause]
out so if you want to be part of that
then go for it
um as I said about a third for the for
the others and all of it for the rest if
you want to help us it'll be great um we
spend 800 hours in there in mostly in
the booths some some in the prep
beforehand but those are just the boring
stats the more interesting part is um we
have a few firsts we are now
intergenerational same as a few other
teams uh the first people well obviously
a lot of people started having kids a
few years ago and now they grow up to
the size that they can actually start
helping out so we have our first father
and son team in the booth which is
really amazing for me um if you haven't
seen the talk uh about frin the the rap
translation was fire
go for it really awesome and we have
another first that's probably not on the
slide we have the first time that we
actually interpreted off of the sign
language usually it's the other way
around I if if you you come from that
area you know that's really interesting
and hard yeah that's us that's
it hi I'm Kati and I'm talking for the
assemblies team
you might know okay this is a congress
we want to see people and where do we
see the people in the assembly Halls
basically um we do all the [ __ ] some
people don't want to do and we organize
everything and try to find nice
neighbors for you um I have some hard
facts for you uh this by the way is Hall
three when it was still empty uh before
the event started so uh unfortunately
the picture is a little too big for the
screen but uh you should get a guess how
this how this structure used to yeah was
set up and how it looked like when there
was nothing on the tables um the most
fun for us um was uh weird or um I'm
just thinking there there's some some
stuff missing before because the uh yeah
because the slide is kind of wrong so I
don't have the numbers right um what do
we do I had some I had some numbers but
um I can I can just recall most of them
I guess um we had 300 eight assemblies
on the place um we had around I think
40,000 shares on 12,500 Square met which
is quite a lot of space if you see
everything um let's see something else I
can't remember 200 tickets in our ticket
system uh various questions also
answered on metrics and everything so we
were always able to to give you an
answer if you had
questions um yeah what there something
else I'm not really sure I don't know
doesn't matter anyway um but we had some
fun requests for placings because you
know basically most people just build up
some kind of assembly have a regional
group or something but some people have
special needs and that's what we also
there for um this by the way was the
planning session we had in front right
before the event started we spent around
12 hours of placing assemblies to make
sure most of it fits it it doesn't
always work out right but we're trying
our best um that was
all um we we actually that's something I
remember now we had 10
relocations because um duuk is happening
um you you might remember hall for year
three it was quite windy in front and
there were tables
we don't do that next time um well yeah
there was this golden bathtub funny
thing is when we heard that on Day Zero
people told us okay we want to bring a
golden bathtub and we were like okay
what kind of space do we have for a
bathtub I mean and it figure out okay
it's just a small one tiny one just to
sit in so it wasn't some art project it
was some theater project and that that
was a prop that was just standing uh
next to for year z um then there's Olga
some of you might know Olga um it
belongs to chaos West but we decided to
give it a little different place because
and everyone walking there can see it
and it's nice and cozy and it doesn't uh
break when someone runs into it because
there's no way to run into it um last
thing is we had an electron
microscope well um we had a request I
think on days minus two or something
where people told us okay we have a
pallet with an electr
microscope okay we figure out with lock
but uh if you want to see it I think
it's still standing in for year
three um yeah um there's a QR code if
you're helping out during the tear down
starting at 7 uh you're most welcome to
uh to get a badge on the Hub yes do you
have Ur text too huh can I find the url
text somewhere uh you might post it on M
I'm not really sure um one thing we want
to tell you now you now you've seen the
building get ideas how we can make it
better next time because it was really
great but I think we can make it even
greater thank
[Applause]
you okay
yeah hi uh we are from the Hub team um
we are doing that stuff with the badges
as well um so yeah what we do um You
probably seen that uh start page um
where you can find the assemblies you
can find the um individual events and
most importantly Ser organized sessions
as well um we had um quite a few of them
um we do more stuff in the background
like the assembly a is um doing the
management of the assemblies there um
but that part is mostly hidden for the
general public so and not that
interesting it's B basically a database
interface um in the screenshot you see
parts of the wiki as well so yeah we had
the most frequently Asked question is uh
why don't I have permission to add it to
the dating page um because someone else
else is editing it uh yeah um How We Do
It
um we um well what what we do is we
integrate different uh schedules um we
had four main sources this year uh and
the fifth one but uh yeah for mainten
the official uh far plan um fire shuns
hexon and Zen Centrum uh we yeah so them
together we throw in the fifth one which
is self organized sessions and the
assembly organized sessions and yeah mix
them together uh do room booking uh so
probably you organize self organization
yourself and uh yeah got the message
that the room is already blocked at the
time slot you wanted to do it and needed
to find another one sorry for that but
uh physical
limitation and uh yeah all that stuff
what we do uh we um put it out again uh
one externals yeah recipient of I of API
is c u c c C3 NF uh who get uh our uh
the points where the assembly team place
the assemblies um that comes from us we
U are a source for the info Beamer so
the um yeah schedule information you see
on the screens uh here um is sourced by
The Hub or at the Hub and we have uh the
yeah apps um for both Android and iOS we
don't do them but we are the source for
their
data yeah that's uh basically what we do
uh in numbers uh assemblies in the
system
299 um that count as a bit off to the
one from the assembly team because we
have we have some uh technical
assemblies in there as well to uh manage
stuff uh in total we had um close to
1,00 th000 events in the system um
several official ones from the imported
sources but from assemblies and self
organized events as well and if you look
at them numbers uh quite impressive in
comparison to the official uh schedule
um batches uh is that shiny feature
where you can uh hunt down uh on the
Congress to explore stuff and uh get a
virtual badge um yeah uh it's um it's a
rather new feature the whole thing is a
rather news uh thing for the Congress at
least and yeah didn't work out that well
this year um not that interesting or not
that good communicated yet uh we will
improve on that uh next
time um projects um as an display what
you do what you bring with you
um can be improved as well but again we
need to do more communication and yeah
what we need to do more is testing in
advance uh we had a lot of uh issues uh
lot of uh import sources which changed
shortly before the Congress because
people woke up and yeah then we had to
adapt as well yeah was a lot of work but
uh right now it's working but uh yeah we
had a little happy accident yes um one
of the main uh incidents we had with the
Hub during this event was that um we had
a lot of functionality already built in
but we also added functionality during
the event and of course uh if
functionality has no UI yet the feature
is not fully developed so for the self
organized sessions uh most of the self
organized sessions just had one speaker
right and there were uh there was one
organized session that uh wanted to have
two speakers so of course what we did
was add this uh person to the self
organized session add it to the database
uh and many of you already guess what
would happen um as soon as the
self-organized session got their room so
they selected a room where they wanted
to participate in or wanted to hold the
session in uh that got added to the
schedule unfortunately that broke the
schedule so uh the schedule could no
longer
regenerate um we had built in a cache we
were forward thinking but unfortunately
after the cash expired um any request
for the schedule built up a huge
database query so this is one of our
largest database queres because it needs
all the events all the rooms and so on
and so on in the end we had a average uh
bandwidth to our database between our
dock containers of 100 mbit per second
so that's quite a lot and of course this
caused a lot of uh traffic but
fortunately as soon as we found the
issue we could remove uh the speaker
from the self organization and
everything went back up um fortunately
for us um a lot of our uh apps and a lot
of our systems that uh ingest our
schedule were able to uh do a stop Gap
measure uh help us uh uh mitigate some
of the impact this outage would have had
so a lot of thanks to them for handling
this issue in the meantime while we
fixed our internal
stuff and
um thank
you
one of the uh apps that as uh we already
said is not uh developed by us but that
ingests uh our data is the iOS far Plan
app uh the developer didn't uh want to
uh come up here uh he just wanted to
tell uh wanted us to tell you that it's
basically the same app uh that you have
known from other C events where you have
IOS and watch OS and other uh Mech
related OS uh things uh with this app
and he has about
6,500 users uh as he guesses it and then
there is the other app and this will be
the next
[Applause]
[Music]
speaker hi good evening um I'm speaking
on behalf of the Android app uh that's
what I'm doing since uh 10 years about
and um uh a couple of you used the
Android app it seems so there's uh by
half an hour ago uh 3,600 installs
that's a bit of a delay by Google play
uh because they uh will present numbers
tomorrow um it's pretty interesting um
seems you were a bit eager to come to a
real Congress because uh already on the
26th of December there were um 2,000
something installs uh so so people uh
were a bit hungry I guess um other than
that um there is of course feedback from
you uh which was uh always welcome um
there was about uh 14 now uh texture
reviews where people request features or
uh discuss box and uh uh ratings went up
I think to
Lei um there could be a higher ratio so
don't be shy uh reach out uh you don't
have to do that on Google Play you can
also reach me by email or uh on
different
channels um new thing this year uh I
distributed like 5,000 stickers on the
Congress if you don't get them uh
there's this sticker for the um project
behind the far Plan app
and you can get them here here if you
want um as I said I found this uh
feedback pretty speaking um people were
really really eager to get the app that
wasn't the case and last year's uh
numbers normally went go up over the
days but this time was very fast uh
there was not too many fuckups so I
could sleep very well um I did not
release uh a new version just one
version was out there all the time so
uh overall people were not affected by
crashes um there was one interesting uh
effect that I wasn't prepared for so
normally um what should happen is if you
load the angle uh the angel shifts into
your app then there gray column comes up
so everything has to be shifted by once
turns out there's a indexing uh problem
which
um uh made the indexes go up to
89 and then a friend said that's not too
bad that's 89 days of
Congress so thank
[Music]
you hi everyone I'm benorian from Kos
Emergency Response Team and some general
effects we literally rolled out the red
carpet for our patients which also
prevented the original one from turning
red we had five treatment stations and
one for isolation uh we have gotten our
stock about uh 16 ,000 uh articles in
over 500 types it took us 5 days of
waiting for delayed deliveries and our
runner shifts really do what it sound
sounds like uh they walked over 1,000 km
uh we handed out about about 110 uh L wh
drink and we
had uh 86 third engs working during the
night let's head over to more patient
related stats uh we had about
8 uh 57 entries in our operation diary
we had about
355 cases uh at with at least uh 100
patches on people about adult ones about
16 on children uh we had 13 times um
related to uh soldering and five times
related to Broken
bottles well our um third angels are
really working fast uh our median
treatment time is 5
minutes
this concludes uh our contribution from
s thank you and now a short um
contribution from the air cleaning
Operation Center uh they had 18 air
filters in operation which cleaned about
uh
2,60 operating hours and about uh 14,000
cubic M of air
[Applause]
power
and the next team will be infect CHS
infection
[Applause]
prevention hello everybody I'm avara
from infections and um let's start with
some infections
Impressions here we have the chaos
impots you see one of our testing and um
mask distribution points and the fairy
dust in the
background then we had our test center
in the uh entrance hall uh you could
grab uh tests and masks there and also
test yourself on site it was quite
nice and uh oh the picture is actually
there's more boxes on top that's just
one day of testing and uh Distributing
masks let's get some statistics we
distributed around 177,000 ffp2 masks
and about 15,000 SE tests and you can
see
in the bottom right corner uh small the
um mask and test distribution per
day we because we had such data we tried
to um calculate and look into the
future so we distributed 177,000 masks
this year we did some quick math uh
mathematical calculations and next year
we expect 66,000 masks and uh the year
after that 200 and 50,000 masks so good
luck to lock with your high Bay
Warehouse they need to build for
[Applause]
that also special thanks to C3 cat for
providing additional safety
equipment
and uh special thanks to our antiva
ation Angels there were more than 150 of
you and we couldn't have done it without
you thank you so
much next up is
heaven hello Hamburg hello Internet I'm
razel from heaven and we will show you a
few things about what we did deploying
all the awesome volunteers here um after
Hamburg we got a new home we went to
Hall X um as you all know formerly known
as Twitter as we were reminded on the
doors and we were the first Contact
point of angels attending to our lovely
event and we also grabbed a few data
points from our Angel system uh this um
morning um I can correct the the first
number because we were eager to know if
we reached the 5,000 Angels but we
didn't at around 70 well
left to that and um from these people
around 4,000 Angels arrived and a few L
did at least one shift so there was much
to do as you can see we had about
roughly 3 years time of plan shifts and
roughly the same number of entries where
we take dates and unplan things and get
a work loock so we had much much things
to do and uh since we all need to do and
create the shifts we also looked in our
locks and um yeah you see more than 50
th uh 56,000 events though so much for
privacy we will incinerate it after the
event so the C3 dumpster fire should
like that and since our Angels also need
something to eat we had some awesome
people beside the machis that provided
rolls for everyone and we got around
3,000 for that so so alth thanks you so
much for the brutin manufacturer for
feeding our
[Music]
Angels last but not least it's also
repetitive to say but this event also
has only been possible by the initiative
of all the volunteers helping here
helping before the event and also doing
tear down so Heaven says uh to you thank
you for your work um we are you're very
welcome and we don't could do this
without you and also on an extra note we
had some issues with these epidemic
events regarding the last year events so
we had some people who do the buildup
but had to leave early because they got
infected and so we wanted to see uh and
say thank you that you did build up um
get well soon and we hope to see you on
the next event that you can attend it
properly with us thank you so much have
a good night and
[Music]
bye welcome this is Daniel and I'm cubid
and we are here to represent the fashion
Operation Center we are tasked with
handing out merchandise at the Congress
and other CCC events for this year's
Congress we had eight products with a
total of 78 size variations it totally
9,509 items delivered to the CCH here
excluding Angel shirts you can see the
the different colors and products over
there we mostly had shirts in black and
then zippers in black and of those 9,500
items around 3.7k were pre-ordered and
90% of the pre-ordered items were picked
up on day one and we are very thankful
for that because that meant we could
prepare open sale that started on day
two only 33 items were not picked up
after the deadline which is like a
really low failure rate so thanks for
that as
[Applause]
well in order to Crunch the Q we need to
crunch some numbers so here's an a
availability chart of the items you can
see if you did pre-order we had almost
all the items available to you except
for some mishaps and then when the open
sales start started on day two first
things to be sold out where black
hoodies and now we only have some fitted
shirt sizes left and then on day to
things got pretty rough but we had some
old merch available for you to pick up
at a great
discount yeah so after numbers maybe
depending on when you came to our happy
place um where we strive to make you
look good for the next year it looks a
bit like this when we arrive so there's
tons of boxes uh most of these boxes are
not sorted by whatever is in the boxes
so we spend a lot of time actually
figuring out what was packed in what
what box and make sense of all of it in
the end this year we really you know
excelled in preparing for the last year
even all of the old merch has been
folded it has been packed up in boxes
again and uh we've actually managed to
sell so many things from the past
congresses even that we are starting
with pretty much of a clean slate for
next year um um
1,494 items were packed generally uh in
our small place we are one of the teams
that can only start working whenever all
of you arrived so it's not so much
preparation but once we start opening it
gets quite busy so in order to try to
minimize the queue that we have so you
all have don't have to wait so long uh
it was 923 Angel hours in total with
around 30 Angels peing uh that we're
helping to make sure that everybody gets
what they want and don't have to wait
for it so long and as you can see in the
picture below we are not you know shy of
anything we even have people playing the
pipe to attract you to sell you stuff
that you might not need but you know
whatever make sure that we don't require
so much space in the storage area
[Applause]
so thank you so much this only works
with a lot of people that are really
happy to make you happy so we are
representing team here thank you so much
for everything thanks for your patience
your understanding and see you next year
in the happy place of the fashion
Operation

with experienced mentors and we've been
doing this since about uh 30 C3 uh
mentors can register on on our on our on
our system they tell they tell a little

th000 postard this is from like noon
today most of them went to Germany most
of the others that didn't go there uh

mail we don't count those however we
used about 38,000
postcards maybe is um we have males for
um 98 future and other events um people
submitted yeah over 600 postcards by the
online office and basically half of them
were already delivered by 12th this
today we offered quite a few Services
you see a mailbox here um we had seven
people where we got uh birthday
celebration deliveries um we did sticker
operation uh support where we delivered
their mail we had a rally where people
could go and do some tasks and get a
nice reward at the end it was about 100
people that did it we had four types of
soing proposals so basically fill out
texts we had typewriters we had uh
mailboxes at various places and also um
we had air mails so basically somebody
made a paper plane out of a postcard and
uh delivered it through the four year so
um that's
new um we want to thank all our chaos
carriers for um delivering mail and
investing quite a bit of time on
researching tricky cases um our angle
for making it possible to actually get
back office work done and uh of you for
writing all the postcards thank
[Applause]
you hey everyone my name is enrio I'm
from the kids space here uh and a
question to you who of you brought kids
to the
Congress okay so a couple of them um
they arrived at uh different um yeah
areas that we had we had like two rooms
um for all of them and we try to unlock
like the Next Generation and I probably
think that some of you um already saw
many many kids here um which was amazing
so we had like an action Zone um we
tried to collect some numbers for you so
we had three unicorns we had six large
tentacles did anyone of you see
them okay so some of them maybe there
are some pictures uh in the internet we
had like seven fish we had like an
underwater world that we kind of built
up um we had like amazing esta bricks
which are like large Legos um that we
ordered for the Congress
and are thankful for the donations that
we got so that we could make this
possible we had 1,24 L of uh Lego Duplo
bricks in there which were uh capable of
building like huge uh structures that we
even need to take care of so that it
doesn't fall on anybody um we had an our
create there with over 3,000 uh
different games and uh someone took over
the part of counting all the balls in a
ball
pit
[Applause]
if you don't trust these numbers you can
just go there and uh or it's it's down
below so go there and uh check it
out okay so also we had a creative Zone
there um which um hosted many of
different workshops we had books there
we had lots of pencils uh we had board
games uh we even had some RPG rounds um
that uh taught the tiny uh kids or the
little ones um how to do this and um how
to get into this world of uh roleplay um
gaming we had a hex Center we had
different game servers Minecraft servers
and we counted that we had over 5,400
day and night shifts on those servers um
yeah and we have countless ideas for the
future um so one one message for you out
there if you ever think about uh
bringing your kids to those uh events um
it's amazing it's a good experience we
had like babies to uh to Elder ones that
go to the hug TCT um and stuff like that
so it's really an amazing experience and
also thank thank you for all the angels
all the uh teams that organize this in
uh before and after um and also uh yeah
thanks for everyone for making this a
safe place for children thank
[Music]
you
so uh we are Nana and blood from the uh
Tock which is the tape operation system
and actually formed only yesterday so I
guess we're one of the uh youngest but
probably also the best or one of the
best organized operating
centers here at the Congress
so our main goals are to raise tap
winers here in
CCC um to protect the CC H from tape
damage so our primary principles are be
excellent to CCH because this building
has feelings
too um and the second one is science and
art so we preserve them we don't change
them so we change
to so um we use quite a lot of resources
actually since yesterday so um during
our action we used uh
26542 M of certified tape this one this
one only use this one
on so so to protect this building only
use the certified tape from to you can
call us one talk and uh we removed quite
the same amount which was 255 M and 65
meters of vicious tape which will damage
CCH um we used the 20 Angel
hours um and during during our service
we walked around 180 kilm or
23,000 steps we used up two package of
blister tape uh drank 8 liters of mat
and uh we also used quite up quite a lot
of patience from the visitors we
estimate around 10K and last but not
least yeah we saved the one
relationships and this is a quite um
important one we saved the relationship
between heaven and hell so the heaven
and lock
[Applause]
so and uh we hope to return next year
even
[Applause]
better
so thanks all of you thanks for all the
amazing teams we have here um I'm from a
rather unknown team which is kind of
good to know that we are not there um
because we have a serious business to do
um since this is a really formal event
as you all know um we had to approach
our guests and to get their um
satisfactory reports on this event
because we want to improve and uh
Computer
Club M which is probably hard to
translate for all the signal Angels out
there um is really interested in making
this a better experience for all
technical oriented people which you are
and which is our target audience so
which made us the or which gave us the
task of approaching people who actually
just wanted to leave this event by
giving them a tedious amount of
questions to answer just right before
they could leave thank
you
um yeah so we actually only included of
course the answers which were uh in our
political agenda and dropped all the
others and I'm really glad that so many
people took part in our questionary and
get made us really good answers what
kind of questions did we ask of course
we first ask why are you leaving this
event which is a good question to ask
but most people just wanted to go to bed
and said oh does it take long uh others
said oh I just want to go outside and
smoke I'll be back in 2 minutes and we
said no you won't be back in 2 minutes
because this takes more than 2 minutes
we are doing here and six person claimed
they have a social life out of the
Congress which we really
doubt yeah um then we made of course a
questionnaire which day of the event is
the best day for you and this is really
interesting that there are people who
actually like day five which is tomorrow
uh and we don't know why they're doing
that but uh probably they want to have
longer Congress so probably that's the
reason why and nobody likes day four
which I don't know because day four is
amazing as all the other days thanks to
all the teams we just heard of
course um yeah we
then we then ask a rather difficult
question in the chaos world because as
you all know we have these angels our
volunteers they doing an amazing job but
since Congress and all the events we're
doing are now getting more professional
each time there's a long discussion
about whether they should be addressed
formally or informal as we're doing it
now and this is the thing we of course
ask whether we should approach or
whether we address our angels in the
future in a more formal way and as you
can see the results are pretty clear
what we should do
[Applause]
there um and then we ask a rather long
question in German which would be
smaller in English and really big shout
out to Mah who who's done the template
for all the slides and who had to had to
live with my style of putting
information in the title um which was
not supposed to do in this template I
think um but the question which is asked
here is um since the event location is
now a bit smaller than liic and since we
could probably run out of space we
wanted to ask whether there is an
assembly which people did not visit and
which we could drop off and it was
surprising that 50 uh 95% of the people
we asked did not know which assembly
they did not attend so we have no idea
why they couldn't help us with this
question um then there was of course a
question how they like the fairground in
lipic
um some people ask us uh well I think we
are in Hamburg right um but there were
actually people who tried to answer this
question seriously um I don't know why
so um but everybody likes it
basically um then we asked of course how
they got the ticket to this event and we
put up some rather strange answers um
actually somebody claimed they bought it
in a DB ryar which is some internet
thing from D some said they bought it in
a local pre-sales office other said they
Bol it in a that's a federal German from
the federal government of Germany where
you where if you were working there you
have to buy your stuff it's called
costers bunders and most people seems to
have bought the tickets somewhere in
this thing called internet we have to
investigate on how this work worked um
yeah we then asked in this Anonymous
exit interview whether the people would
give us their Mastodon handle um we were
surprised that 11% did not have Mastodon
and we were even surprised that more
surprised that 25% of attendees or
people who answered our questions um
gave us their Mastodon handle for an
anonymous exit interview but yeah well
thank you for that we will think about
what to do with those those
handels um so and then there were some
rather difficult questions as you know
we have large Services here which doing
a great amazing job every year you heard
most of those just today on this uh
stage and we puted one of the core
services in the Congress which is the
phone network currently as you know the
phone network is sponsored by the
organizational crew by the project
liting of course um but in the future it
could be that due to budgetary reasons
or others we would have have to um ask
for small fee so we ask our attendees
and the people who answered in the
survey whether they would be willing to
pay for the services of the event phone
and we are really happy that only 25%
said they would pay for the service and
most people said they would actually
give some like chip in five or something
so big hint for the invent phone you can
increase your service costs and it will
still be pable of course we won't do
that um but then we ask another question
question which is also really
interesting um so as you know there is
some internet and Network Services
provided here and it could be that we
have to get money for those as well so
we asked the people how do you want to
pay for the internet of the Congress and
we gave them four answers they could
answer uh one is uh based by time so how
long you use it um which is the blue one
only 10% um 177% would be uh willing to
pay on a volume base so probably they
don't use it that much
um that won't be the pixel flute guys
and um 29% claimed they would pay for a
per device cost so like per Mac address
or something like that and 41% would be
willing to pay by consuming at a bar so
we offered them the chance of buying a
mat and then getting like three hours of
internet and 49 no 41% said well I would
do that so thank you for being able to
help here um so so and then as you know
having the Congress is really really
expensive so we looked into how could we
lower the cost and there is of course
the European Union which has some things
like the European stability fund where
they give you money if you um do things
in areas with less developed economy so
one of the ideas would be okay let's
move the Congress to areas where the
economy is not that modern not that good
like bararia or something
and so we ask how long would the people
be willing to travel to another Conquest
location and of course they had to give
us the answer in nautical miles because
it's the European Union thing don't ask
wait don't know I didn't make the
questionary is just something um most
people were able to calculate the miles
great for that and most people were also
willing to go to Bavaria as you can
see um then we ask of course how the
people arrived here which is also a
really important question and we tried
to give the um when we made it up we
tried to get the best answers so that
people really found the way um some
arried by boat or claimed to be some
people arrive by plane some by bus some
by truck um and strangely 85% use some
other transport vehicle we didn't think
of um so sorry that this static is not
statistic is not really
helpful um yeah and as I said it's a
customer satisfactory interview and we
ask of course on a scale from 1 to 23
How likely would it be that you
recommend Congress to all your peers and
we're really happy that most choose 23
so thanks for me thanks for having fun
here and thanks for all the teams which
did really work
here hope to see
[Music]
[Applause]
[Music]
you this B now wa ah yeah now you can
hear me and with all of that thanks to
all the team thank you for coming here
and and I've got one last slide from C3

this house without being told so unless
it's your own thank you and see you next
