I can't seem to concentrate today, so have some porn!

I've been reading Prakesh & Knister's 1994 paper, "Undoing Actions in Collaborative Work: Framework and Experience," because I'd like to implement an undo feature in my web applications, especially the ones for Isilon but also elsewhere, but I can't seem to concentrate. Maybe it's too much caffeine. And this is only the first paper; after I finish it, I have to go on to Zukowski's Implementing a Selective Undo Framework, which uses Python as its reference language and was written itself in noweb. (It completely sucks that Emacs 22 doesn't support the noweb.el that ran in Emacs 21).

My life is so exciting.

Here, have some softcore porn masquerading as an AIDS prevention ad:

For the boys.

For the girls.
