Presentations

Found some old presentations

While doing backups of my important personal stuff (this website, my code, etc), I found some presentations I'd done in school: I also removed a pile of comments that were spam or people testing the comment system. Some comments had unicode characters in them causing python to barf (I have a python cgi script that helps me search/delete comments), but doing .encode("latin-1") fixed it.

There were only a few spams that got past my scripts. I might add word filtering to the pyblosxom comment plugin so crap mentioning viagra and cialis won't even be permitted. Still seeing these happily in my logs:
