I'm always mindblowned by the sheer number of networking equipment deployed and maintained during the conference. They now have[0] 5000 WiFi clients connected, downloading with 2.70 Gbps and uploading with 8.93 Gbps. It's like, once a year, a big part of the internet traffic is routed through Hamburg.

  There is a congress saying: USE MORE BANDWIDTH!! :)
  - eeZi 11y ago
    Literally. They once has a 100 Gbit upstream, but it wasn't maxed out, so now there isn't. It's "only" 40 Gbit now I think?
- asuffield 11y ago
  It's a lot for wifi, but not that much of the internet. Less than 1 NIC ;)
- mtgx 11y ago
  Are their servers overwhelmed already though? Hall 2 conference seems to be freezing now. The CCC is probably a good place to be experimenting with streaming over Webtorrent or something like that.
  - noinsight 11y ago
    Yes, I switched to the SD stream, it's good enough.
  - Vespasian 11y ago
    The servers are always a little bit under stress at the ccc. PS: Reporting live from hall 2. good talk so far ;)
  - nathankunicki 11y ago
    I'm sitting in Hall 2 - WiFi is working like a dream. :) Edit: Their online infrastructure is probably seperate though.
    - smartbit 11y ago
      voip calls work fine too, sometimes a brief drop
- wslh 11y ago
  Someone in HN who can share some information about how to setup WiFi for high-demand? In any place I go (e.g. airports, restaurants) the WiFi is terrible.
  - voltagex_ 11y ago
    You get what you pay for - a public place using a consumer grade WAP is going to have a Bad Time.
    - wslh 11y ago
      But is that the only reason? I imagine there are issues related with configuration, sharing the same medium, distances, small interruptions when you move from one connection point to another.
      - voltagex_ 11y ago
        I've been downvoted, probably for not giving enough information. A lot of the time the WAPs only have 16-32mb of RAM and some kind of hardcoded limit to the number of DHCP leases they can give out (if they don't just exhaust the range instead) Your local Starbucks probably has half decent Cisco gear, but the independent coffee shop around the corner bought the cheapest WAP in the last Black Friday sale. The firmware hasn't really been touched since 2008 and is running a buggy version of dnsmasq, miniupnpd and an out-of-tree Ralink driver on top of kernel 2.6. If you think I'm lying, have a look at the firmware of any non-802.11AC DLink or Netgear router. Both companies are getting better but they're at the mercy of the SoC manufacturer (Broadcom, Ralink etc). 802.11AC routers seem to be getting better, mainly due to the bandwidth requirements finally getting beyond 200-400mHz MIPS chipsets. Although [1] might be taking it a little too far. [1]: http://www.dlink.com.au/home-solutions/taipan-ac3200-ultra-wi-fi-modem-router http://www.dlink.com.au/home-solutions/taipan-ac3200-ultra-w...

  5k wifi users doesn't really sound like "a big part of the internet" to me, or even necessarily a "big part of Hamburg."

"Use a desktop player! Browsers and video doesn't go together well, even in 2015 and especially when it's live. So for your best viewing experience please use a desktop player like VLC or mplayer." Am I the only one to be bothered by this comment.
- dijit 11y ago
  Why are you bothered by it. It's true. HTML5 live streaming is only reasonably done by Apple and only works in Safari. I wouldn't push flash video streaming if I were them either. Which leaves streaming over http (not using the browser) or rtmp
  - DaGardner 11y ago
    I have no problem streaming with Chrome Mobile iOS... Works really well.
  - kzrdude 11y ago
    Firefox works fine, vlc does not. Not bothered though.
    - dijit 11y ago
      Fair enough. I've been trying to do live streaming in an automated fashion and always failed. Mostly it's apples way or the flash way. Everything else is absurdly hard to maintain.
  - rst 11y ago
    Firefox's built-in mp4 player is working for me well, for both live streams and recordings (the "re-live" section of streaming, which has all the talks that happened before folks in America woke up). So, they're at: http://streaming.media.ccc.de/32c3/relive/ http://streaming.media.ccc.de/32c3/relive/ BTW, there's also a flash player for the "re-live" stuff, which isn't working for me on Linux at all; if you're having trouble with it, try the mp4s. (Just as well; I get to shove the flash-enabled browser profile back in its box.)

45% Insecure WiFi traffic? at a Hacker Conference? :)
- zymhan 11y ago
  I'll wager there are more than a few honey pots
- xorcist 11y ago
  Why? I long made a point of only running "insecure" network layers at home. I sincerely believe in the stupid network, and that any security belongs above the transport. Using the term for wireless networks at home really drives the point home that you're supposed to get your personal connection and buy your own access point, so that IP addresses finally can represent identity. That is not a coincidence.
  - emptybits 11y ago
    I was with you until "so that IP addresses finally can represent identity". You don't mean actual (personal/account) identity, do you? IP addresses represent a location for delivery and they definitely identify a network interface, but that's the extent of goals for IP addressing. Courts have supported this view and I think that's a good thing. Sorry if I read too much into what you said. EDIT: spelling.
  - dimdimdim 11y ago
    Keep in mind though, that once your Layer 2 is hijacked, a lot of attacks are possible before upper layer security kicks in - things like browser redirection and exploitation are very common these days
    - urda 11y ago
      Please take note of this folks. Simply trusting "transport security" isn't enough. Please do not seriously run an open access point because you think it's just as safe as the OP.

Is there a place where recordings get saved once they're finished or will I have to wait until the end of the conference? My internet connection is too unstable to watch them live.
- lorenzhs 11y ago
  Automatic stream dumps are here: https://streaming.media.ccc.de/32c3/relive/ https://streaming.media.ccc.de/32c3/relive/ -- note that they're completely automatic, no editing has been done. They include the 15 minutes before and after the talk in case it starts early or takes a bit longer. The video operation centre will put finished releases up at https://media.ccc.de/b/congress/2015 https://media.ccc.de/b/congress/2015 once they've finished processing. Those include translated audio (all talks will be available in English and German), subtitles, intros and some audio processing.
  - r3bl 11y ago
    Thanks! Downloading three talks that I really want to hear right now. I'm perfectly fine with watching them unedited.
