Many talks from DebConf are streamed live. Hopefully this one will be available to also watch later, sounds interesting.
Arch wiki is the definitive wiki for Linux. I also refer to it regularly to help with issues on Debian. Debian wiki is OK mostly but some pages don't get enough love and become outdated, and some don't exist.
Well, the bright side to all this is that I now have Arch installed on a machine with 8 GB of RAM. I can run mainstream browsers like Firefox and don't have to use the "lightweight" browsers any longer.
