In this post I suggest a way to have an encrypted Linux installation on a USB key, which to me is useful when I travel and I want to securely access the functionality that desktop Linux offers.

Inside the Linux kernel documentation, Linus Torvalds goes so far as to mock GNU coding standards: First off, I’d suggest printing out a copy of the GNU coding standards, and NOT read it. Burn them, […]
