Well, this is an article about programming, not a program, and it's pretty insubstantial. All it really does is mention some buzzwords and and note that they're the foundation of the "pyramid of code quality". Nothing personal against the author, but it's pretty flat for something that's stayed on the front page through evening. I wonder why it's getting voted up.
This article on ssh (http://sigusr2.net/2009/May/07/hacker-utility-belt-ssh.html) barely scratches the surface, too. At the very least, I'd mention ssh-agent (a good intro: http://mah.everybody.org/docs/ssh) and visual fingerprints for host keys (http://gwolf.org/node/1864).
But, I really should be constructive and write something myself, rather than just griping here. It's much easier to complain about other peoples' writing than to write. One of these days...
