Fritz Onion slides and demo code

Fritz also blogged recently about how he keeps his notes - a local install of FlexWiki. That beats the heck out of my http://notepad.yahoo.com/ solution - FlexWiki is versioned, searchable, interlinked, etc - kind of like a really light OneNote. I've often thought if I ever write a book, I'd like to build it up from a Wiki.
