HOPE had 10gbps core and it was more than enough
<
balrog>
they had good distribution
<
rqou>
yeah I'm surprised how bad the defcon network is
<
q3k>
rqou: CCC had 400gbps on the edge last year
<
q3k>
but yeah, this is absolute baby grade
<
q3k>
rqou: peak internet traffic at ccc was around 40gbps iirc
<
rqou>
i meant edge in the sense of "the user side"
<
rqou>
i know uplink was like 400gbps
<
q3k>
yeah, 10gbps at the yoloclo
<
q3k>
iirc we brought a 2x10gbe machine and did saturate both links last year
<
rqou>
10gbps at the tables too
<
q3k>
yeah, but only if you pulled the fibre yourself
<
q3k>
early on so that fire inspection would pass
<
q3k>
standard switches were 1gbe uplinked
<
rqou>
the table near openfpga was 10g?
<
q3k>
you got lucky then
<
rqou>
i was using the second port on the switch with a DAC cable
<
q3k>
not that you can really saturate that from a normal machine anyway
<
rqou>
yeah, my flaky-ass nehalem with a connectx2 just kept crashing
<
q3k>
on most laptops a simple nc-like tcp client/server peaks at around 4gbps
<
rqou>
anyways, i probably got lucky because there was a wifi AP on that switch
<
q3k>
but yeah defcon is so underwhelming
<
q3k>
rqou: just checked
<
q3k>
rqou: meanwhile at 34c3 our box alone pulled in at least 29T of data from the internet
<
q3k>
rqou: how quaint
<
rqou>
O_o doing what?
<
q3k>
uhm, copying ubuntu isos from the internet
<
q3k>
i think we just pulled everything we could find from open FTPs
<
q3k>
but i guess some of them were also on the congress block
<
rqou>
I was finding most of the congress ftps were super flaky last year
<
q3k>
they're always flaky
<
q3k>
because FTP is a terrible protocol
<
q3k>
and all implementations are shite
<
q3k>
and they were never meant to handle more than 100mbps of traffic :P
<
rqou>
yeah that's about how much bandwidth i was getting
<
q3k>
but it's mostly really about concurrent access
<
q3k>
when you've got hundreds of people trying to download multiple files at once it all breaks down
<
q3k>
it'll queue up and then outright reject any other control connections
<
felix_>
only 400mbit/s uplink o_O at least that explains why the internet connections was rather bad...
<
q3k>
there's literally a faster internet connection at the warsaw hackerspace than at defcon
<
felix_>
the gulash programming night in germany had 120gbit/s uplink for maybe 1,5k people ;P yes, 120 gigabit, not megabit
<

>because FTP is a terrible protocol

Just finished scheamtic capture on the starshipraider v0.2 io cell
<

a few ferrites are my secret weapon
<
rqou>
ooooh you're relying on them to saturate aren't you?
<
azonenberg_work>
No
<
azonenberg_work>
i'm not
<
azonenberg_work>
i'm using them to split the AC and DC paths
<
rqou>
lol how boring :P
<
azonenberg_work>
ferrite on one side, cap on the other
<
azonenberg_work>
then all the fun protection stuff on the DC path where it wont touch the fast edges
<
rqou>
did you see my message late last night?
<
azonenberg_work>
i saw you link to some adc
<
azonenberg_work>
but didnt look at it in detail
<
azonenberg_work>
top image here btw
<

is what i'm doing w/ the ferrites
<

ok, open it and read the title completely
<

and then tell me what you think about possibly adding it to hashtag badgelife :P
<
gruetzkopf>
rqou: only with external funding :D
<
azonenberg_work>
so you want brainwave cat ears hanging around your neck?
<
azonenberg_work>
:p
<

lol not quite :P
<
rqou>
just led cat ears on a headband (hopefully more comfortable to wear)
<
rqou>
gruetzkopf: i mean, it's not
_that_ bad
<
azonenberg_work>
gruetzkopf: you want a fun adc to use on a badge
<
rqou>
hmm, exercise (for whitequark?): detect drunkenness with a shitty diy eeg of this type
<
azonenberg_work>
nice little 68-VQFN, so will fit on a pretty small badget
<
azonenberg_work>
badge*
<
rqou>
lol oscilloscope badge?
<
gruetzkopf>
k$+ badge :D
<
azonenberg_work>
of course, the big FPGA you need for the 8 lane JESD204 interface wont fit so easily...
<
azonenberg_work>
And yeah its about 2 kUSD a pop iirc
<
rqou>
so that makes for a $5k-$10k badge?
<
rqou>
cash only of course :P :P
<
azonenberg_work>
lol
<
rqou>
and if you manage to actually sell ~20, then you can walk around vegas with $200k cash, what could go wrong? :P :P :P
<
azonenberg_work>
hey, if you're lucky at the casino
<
azonenberg_work>
you might have enough left over for a pack of M&Ms at the airport
<

azonenberg_work is a high roller :P
<
azonenberg_work>
rqou: is that what you call it when somebody is rolling a second joint after smoking the first?
<
azonenberg_work>
:p
<
rqou>
looooooooooool
<
rqou>
wtf azonenberg_work
<
rqou>
hmm, further exercise for whitequark or somebody: detect if somebody is high via a shitty eeg
<
rqou>
led cat ear modes: relaxed, alert, drunk, high :P :P
<
rqou>
i think that covers most of the mental states of hackers?
<
azonenberg_work>
lol
<
azonenberg_work>
what about "exhausted" or "needs more club mate"?
<

ok, we can see if we can distinguish "exhausted"
<

as for the second, this is vegas not germany :P

either way i think you will make some people unhappy with that
<

12GBP, am citizen, easy enough :D
<

ah, in the uk
<

it's literally web form+paypal

that's probably fine, brexit will make them irrelevant anyways :P :P :P :P :P
<
gruetzkopf>
and that's why i'm keeping both ;)
<
rqou>
actually, i wonder why the ads1299 hasn't made its way into more hobby projects
<
rqou>
it's not a new part any more, and there's openbci
<
rqou>
but i would have expected a lot more people to mess with it

yeah well not everything can be just a shitty set of leds :P
<

hey, at least i package them with phototransistors
<
rqou>
i was mostly talking about the shitty addon system
<
rqou>
other random question: does anybody know how to actually source electroluminescent paint?
<
rqou>
(yes, if i can get everything i want to do to actually work, i think i'll end up with the most unusual "badge"life yet)
<
gruetzkopf>
rqou: do not use yourself as EL electrode.
<
rqou>
yeah, isolation will probably be important
<
rqou>
fortunately i only have to go for "good enough to not die"

since i know for sure i cannot get something "proper" in the form factor i want

(hello to those of you I met during summer camp)
<

well, um, not
_principally_
<
cr1901_modern>
I imagine that was a joke
<
qu1j0t3>
one never knows on irc
<
noopwafe1>
well, you have to implement your display logic on something, and then you need a toolchain, so I guess FPGA RE is cool too
<
rqou>
god i hate McCarran airport
<
noopwafe1>
not enjoying your last chance to be surrounded by bleeping slot machines?
<
noopwafe1>
(but yes, a joke. I am also at mccarran waiting for my flight but thought I would drop in here and start idling.)
<
qu1j0t3>
wait, there are slot machines
_in_ the airport?
<
tnt>
qu1j0t3: of course
<
tnt>
qu1j0t3: it's vegas ... there is slot machines everywhere.
<
qu1j0t3>
oh. didn't make the connection. so to speak
<
noopwafe1>
was sitting at my gate and there were slot machines on all sides I could see
<
qu1j0t3>
gotta squeeze that erry last cent out
<
rqou>
noopwafe1: which gate?
<
rqou>
noopwafe1: if you're in terminal 3, come say hi to me at the burger king?
<
rqou>
also, interesting tsa experience: bag goes into scanner, 100% blue because full of electronics, flagged for extra inspection
<
rqou>
guy opens it, sees my extra defcon badge, asks me "did you go to defcon," and then gives up inspecting the rest :P
<

wow, a clusterfuck at the expediting position at the burger king
