The videos from the recent #CentOSDojo at #CERN are now available on the CentOS YouTube channel. If you have time for only one, be sure to watch the first video, which talks about the challenges that CERN has with the enormous amount of data they produce every day in the LHC.
Also recommended, Fabian's discussion of the coming (and already in place!) changes to the CentOS Git infrastructure.
[UPDATE: The videos which were previously updated were truncated, and we're looking into fixing that. meanwhile you can view the video on the event schedule by clicking the paperclip icon next to each talk title.]
