DIY Baby Rocker, Unix Systems Glory, Encrypting Ephemera, and Explaining Creative Joy

1. Linux Baby Rocker -- inventive use of a CD drive and the eject command ... (via Hacker News)
2. I Like Unicorn Because It's Unix -- forceful rant about the need to rediscover Unix systems programming. Reminds me of the Varnish notes where the author explains that it works better because it uses the operating system instead of recreating it poorly.
3. Encrypting Ephemeral Storage and EBS Volumes on Amazon -- step-by-step instructions. (via Matt Biddulph on Delicious)
4. You Have No Life -- if a video smacks even slightly of concentrated effort or advance planning, someone will inevitably scoff that the subject has a) "too much time on his hands" or b) "no life." Ten times out of ten. [...] After six years I lack a succinct, meaningful response to my students' defensive, clannish embrace of mediocrity, though I'm grateful for this tweet, which comes pretty close: dwineman: You say "looks like somebody has too much time on their hands" but all I hear is "I'm sad because I don't know what creativity feels like."
