Screaming Penguin - Source Does Matter

OpenBSD, the most secure operating system in existence (boasting "Only one remote hole in the default install in seven years") has just released a new rev, 3.3. Beyond the hype of the taglines OpenBSD really is great stuff, I have only used it a few times but if you really need to build a secure machine, OpenBSD is the way to go.

Please support the project by picking up a "puffy" T-shirt or something, very cool people (these are the same folks that bring the world OpenSSH).
