  Those security entries for security and ethics makes me want to shut down my computer and disintegrate it to individual atoms. Its like the technologist handed STASI their wet dream while trying to improve the world...

    > Its like the technologist handed STASI their wet dream while trying to improve the world... The error here is assuming that for all technologists "[handing] STASI their wet dream" and "trying to improve the world" are mutually exclusive. I am beginning to think they knew[/know] exactly what they were[/are] doing.

        I can not agree with applicability of that aphorism in this case. We have had a very vocal feedback loop of raising issues ("stupidity", "misunderstandings", "neglect") with OP conference as one type of such feedback. Nothing has been corrected. Do you happen to know of another aphorism that covers the "willful stupidity", "willful neglect" etc. and what it all means (as I certainly don't desire hitting London.) Obviously those with their hands on the production pipeline of tech disagree with the feedback. Is that really a controversial observation? Really?

I searched through the schedule and didn't find State of the Onion. That's unfortunate. Security Nightmares seems to be still going. That's always a good talk.
- myrion 10y ago
  I think that's to avoid the whole Jakob Appelbaum kerfuffle. Both he and the rest of the TOR leadership were banned from giving talks this year.
  - shawn-butler 10y ago
    That seems anathema to the stated aims of ccc. Do you have a reference for this or personal knowledge?
    - myrion 10y ago
      Sadly just people I talked to. As I understand it, they felt that the technical stuff would be overshadowed by other stuff, and that things weren't clear enough, so instead of potentially picking a side, they refrained from both. Unfortunately this is all second or third hand, so take it witha grain of salt.

  That is cool! Looks like something like Zabbix. Any idea what it is actually?
  - yati 10y ago
    That's Grafana[1]. You can build such dashboards from data in Graphite, Elasticsearch or other sources. IIRC, they now also have support for alerting based on these metrics (something for which we are using Bosun currently). [1]: http://grafana.org/ http://grafana.org/

      They also support pulling data from zabbix, which can be super handy. :D

Are they doing quality control on submitted talks this year, or are they still fine with talks that spread outright and clear lies to people who come there to learn and don't know any better? Edit: They still let Rubin talk, so probably no quality control.
- k__ 10y ago
  Care to elaborate?
  - Mithaldu 10y ago
    For two years in a row Rubin has given talks about Perl, "exposing issues", in talks that are 99% straight lies or at the very least gross misrepresentations. They cannot in any good conscience be characterized as anything other than intentional trolling and spreading of FUD. He has been thanked by CCC orga directly for his contributions as well, thus making it clear that they support such shenanigans. As far as i am concerned, every talk at CCC is highly suspect, since they either don't give a damn as to whether it is correct, or they actively support talks being given in bad faith to an unsuspecting audience.
    - thewavelength 10y ago
      Or you just simply have to accept the fact that congress is more than 100%-always-correct-scientific-talks but rather is about entertainment too. And that is a thing Rubin can bring to congress.
      - Mithaldu 10y ago
        His talks were in the Security track, not the entertainment track. At no point in the talks did he acknowledge that it wasn't meant to be factual either. Additionally, there's a wide gulf between 1% correct and 100% correct he could've aimed for. I would be understanding if the CCC orga put him in the entertainment track, but they did not do that for two years in a row despite having received feedback. He was intentionally spreading misinformation and the CCC orga supported him in that. These are simple facts.

I recently came across the software they use for mixing their livestreams, and it looks really useful for anyone trying to build out a system to stream or record talks: https://github.com/voc/voctomix https://github.com/voc/voctomix
- dividuum 10y ago
  And if you have seen the intermission screens and wondered how these work: They run my software info-beamer (https://info-beamer.com/hosted https://info-beamer.com/hosted) on a Pi3 in each Hall. Basically those intermission information screens are written in Lua. My info-beamer software uses both hardware accelerated video decoding as well as OpenGL(ES) to make things run smoothly. I'll release the complete Lua source code early next year. If you want to see how these worked last year, take a look at https://github.com/info-beamer/package-32c3-screens https://github.com/info-beamer/package-32c3-screens

    > Our operating system detects even the tiniest corruption to files and will automatically restore them from our service. The system is completely self-healing. Can you share details here?
    - dividuum 10y ago
      Sure. The base system is quite minimal an runs from a squashfs read only image. Total size is ~40mb. The squashfs file is stored on the first partition (FAT formatted) which is not mounted rw during normal operation (only while updating the system which happens rarely). The second partition is the data partition. It stores images, videos, the Lua code and other files that are required to actually show content on the screen. This partition is mounted rw. info-beamer hosted always stores those files using content based addressing. So every file that enters the system gets hashed and is then addressed by that hash both on the website itself as well as on the devices. On the website this might look like this: https://cdn.infobeamer.com/dynimg/blob/image-c40ba24410fb9caddeedfb4a8fba7471~lkpAslpl https://cdn.infobeamer.com/dynimg/blob/image-c40ba24410fb9ca..., on the device they end up on /space/cache/<hash>. This is great for all kind of reasons: Cache invalidation and offline verification. For the website, all files can be cached indefinitely as the url changes once the content changes. On the device each file required for a visualization must only be downloaded once, as it's trivial to see if the same file was already downloaded earlier by just comparing filenames. So fonts that might be shared by visualizations are only downloaded once. Also the device can trivially verify that all files are still correct by hashing all cached files and comparing the result with the filename. If it matches, the file is correct. If it doesn't, something is wrong and a new sync is started to repair the problem. Works pretty well. Does that help?
