• I don’t think I’ve seen this before: Very old UNIX releases, listed for running in emulation.  (via)

• Someone with a HP passport login want to help this guy?  He just needs to reinstall Windows in IDE mode, or perhaps find the right sysctl to toggle.

• Where Did the Internet Come From?
• The map for Adventure.  (via)
