  • Big big big THANKS! to those seeding streams on PirateBay!
the streams are too overcrowded. So it is the only way to get the stuff in a watchable quality and in a reasonable time. thx FEM for stream and thx to everyone seeding! --Enko 18:29, 28 December 2008 (UTC)


  • There is no *.torrent file for these two recordings:
 25c3-2997-en-locating_mobile_phones_using_ss7.mp4  
 25c3-3015-en-rapid_prototype_your_life.mp4

  • The upload of new torrent files hasn't been started. It will be fixed ASAP.


  • Is it allowed to watch the ipod versions with other mobile devices and smartphones too? They play well on my mobile. (The .mp4 versions don't.) --N00b 20:56, 1 January 2009 (UTC)
  • Why shouldn't it be allowed?



  • After three times torrent download, md5sum failure on this:
 25c3-2806-en-building_an_international_movement_hackerspacesorg  

--ksandre 05:15, 3 January 2009 (UTC)

    • the sums should be:
 1dfb19d62616329a3f96f3f7a6caa83c  25c3-2806-en-building_..._hackerspacesorg.mp3
 cf8619f13b4364bb07003dc0b28d655b  25c3-2806-en-building_..._hackerspacesorg.mp4
 7ce9de19118037f4437f360d461396e2  25c3-2806-en-building_..._hackerspacesorg.ogg
      • (Sorry I did not specify format previously!) The md5sum I get on the downloaded mp4 is:
  72e0647c26d0fe9260941e7892eff44a  25c3-2806-en-building_..._hackerspacesorg.mp4    

(The above on the mp4 which fails against the downloaded *.md5 file.)

The mp4 filesize I download is:

  527683799 2009-01-04 14:54 25c3-2806-en-building_..._hackerspacesorg.mp4    

This is also different from all other filesizes seen in remote directories (and from the .listing downloaded from the mirror site, which is "527408635" - that filesize is yet again different now when I view from the links on this page.). This is the fifth time I have downloaded from scratch with new *.torrent and *.md5 files (starting with "pre-release"). I always get the same result (file size and md5sum failure). All other downloaded files are fine.

        • Sorry, it may be that we re-released that file and that there are old torrent files out there or something. The MD5 I gave is correct (just checked), the correct filesize is 527.408.635 and mdate is 2008-12-30 16:34. HTH --atze 10:24, 7 January 2009 (CET)
          • No "sorry" necessary! The reason I started this in the first place is that is the only one which has this qwirk. Unless you mean an *.mp4 in the torrent swarm elsewhere, "old torrent files" is not implicated as each time I downloaded this lecture, I started with newly downloaded *.md5 and *.torrent files after deleting all old files (including the *.mp4). (IOW, I have kept current with FeM updates to *.torrent and *.md5 via a dewy/FeM mirror.) --ksandre 13:58, 8 January 2009 (UTC)


  • @FEM, some md5sum doesn't match on this dir, please check on the server:

    • recreated them yesterday, they should all be correct. THX for hint --atze 10:26, 7 January 2009 (CET)


I'm wondering: Will there be recordings of the fourth day or where those not recorded? (I missed the last day, sadly.) I'm asking because they don't appear in the pre-release lists. Specifically interested in the Wikileaks and Quadrature du net talks. (Assuming those where held at all...) --Minx

  • Quadrature has been released yesterday. the Wikileaks lecture is like all other lectures which has been longer than 1 hour 10 a problem atm because of the avi-container we use in our encoding-pipeline could not be bigger than 4Gb (which is about 1:11). But we are about to fix this. Generally we could say that we have recorded all 93 Events. Only the Opening Event could be a huge problem. iirc we got no audio signal from ambion at the beginning :/ (like every year ://)

[edit] Copyright license

Thanks to all those who have been working hard to provide these recordings. This page should state the license under which the videos are available - are they all under a Creative Commons NC-ND license (like the Proceedings)?

If so, I think a more free license should be chosen for future Congresses. The "non-derivative" clause of this license makes it illegal to publish remixes, translated/subtitled versions or even excerpts of the talks. The "non-commercial" clause sounds good in theory, preventing big corporations to make money from the content without permission, but in practice is much more likely to hurt small blogs/vlogs which use Google Ads, and does very little to preserve commercial opportunities for the copyright owners (here: Congress camera people and/or speakers): http://freedomdefined.org/NC. Both clauses prevent reuse in free content publications such as Wikipedia or free software documentation which uses the GFDL. Cetron 13:29, 9 January 2009 (UTC)


The license is being shown in every video file (at the end) and in the meta information of every released file. It is something like CC-BY-ND-NC2.0. Maybe you put the paragraph about a more free license on the FeedbackPage ? Atze 18:38, 12 January 2009 (UTC)
