For those who follow such things

Some of you probably already know cipherpunk, aka Robert J. Hansen.  I have created a LiveJournal feed of his computer-security discussion blog, Known Plaintext (or, more properly, syndicated his existing RSS feed of it for LiveJournal), as known_plaintext.

Those who pay attention to such things will find it interesting reading.  His most recent article, for example, discusses certainty — the question of what you know (or think you know), and how you think you know it.
