Background: A shake-up at work has me feeling like I should be looking around again. My job is actually more secure than ever—they are even offering a rather large retention bonus if I stay—but I’m disappointed with management’s handling of the difficulties and most of my favorite co-workers are gone. They were a big part of why I’ve stayed.

I have a *little* CS training but most of it is ancient. Perl being high level has shielded me well from the bare metal of the stuff. I can follow most things fine but I don’t know how long it would take me to write a sorting algorithm from scratch, for just one example. I do know it’s longer than you get at the white board in a technical interview. And there are plenty of things I’m sure I’m not even aware I should know. Node traversal, edge detection, binary math… I can work from someone else’s “math” but I’ve got few chops from scratch.

What are the best resources, tutorials, code tests/challenges, etc to get my head above the waves?

Thank you!
