For programmers only
I have yet to finish updating my CV and get started on finishing the new engine for the site, but I had to post this excellent article at ACM Queue by Gregory V. Wilson: Extensible Programming for the 21st Century. It's a long read, and only fellow programmers need bother. I found it very interesting; maybe you will too?
Via a totally clueless Slashdot story. (680 comments and counting, most of which are deeply misinformed, as people haven't bothered to read Wilson's piece.)
