Gunnar Wolf is a Debian developer who writes about free software, Raspberry Pi firmware, PGP, Emacs and Python.
HN links it for his posts on free firmware for the Raspberry Pi; commenters also note broken links and one calls a post insubstantial.
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...
The e-mail includes a couple of links. The linked site at http://gwolf.org/node/4070 returns "page not found?" for me currently. Here is an archived version of that page which works: http://archive.is/sSXvX

This direct link to the post seems to give a page-not-found, even though I can read the post via the index page at http://gwolf.org/blog
