It's been a while since I've posted. We moved across the country, from Newport to DC, and I start in a new position tomorrow. Maybe I'll get some time to read/write, maybe not.
The most noteworthy book I read recently was The Unix Philosophy by Mike Gancarz (looks like this is an updated version, I read the one with the 1995 copyright date). It's a great read, especially for philosopher-programmer types. If you prefer the tldr approach, wikipedia's short summary pulled from the first chapter and the second answer in this thread, taken from Classic Shell Scripting, a great example of the Unix philosophy at work.
