Geneaology of computer languges. I'm sure I'm late to the blogosphere with that one, but what the heck, I was away from blogs for the past three days.
This is a partial geneaology of programming languages from Fortan, Algol, and Cobol to C#, Java, and Python. I'd take it with a grain of salt (It misses the morphing of Smalltalk into Squeak for example), but it does offer some interesting perspective.
