According to Nate, the Ruby on Rails site is (still) powered by PHP.

…but then, so is this site. ;)

Update: Adrian is quick to point out that the Django site is built on Django. Also, I believe the phrase is “Eat one’s own dog food.” But I think I like the Nate-ized version better. Heh.

Quoth Shane Sherman in his list of The 5 Books that Every Programmer Should Read:

Over the years I have read many programming related books, and there are a few that really should be required reading for anyone who develops software. All of these books are language-neutral and cover ideas that pertain to any kind of programming. These are the cream of the crop. I would not trust a developer who has not read at least half of these book.

Check it out.
