SysAdvent has started its second year. SysAdvent is a project to count down the 24 days leading to Christmas with a sysadmin tip each day. Last year Jordan Sissel wrote all 24 days (amazing job, dude!). This year he has enlisted guest bloggers to help out. You might see a post of mine one of these days.
While I don't celebrate the holiday that the event is named after, I'm glad to participate.
