You’ve got to watch Patent Absurdity
You absolutely need to go download Patent Absurdity, a new short documentary film funded by a grant from the Free Software Foundation. If you didn’t think so already, you will see how ridiculous software patents are, and the damage they are doing to creativity and innovation in software.
I’ll make no arguments here, but I’ll tell you my favorite part is where a fellow mathematician explains the patent granted to eharmony.com. Insane!
If you don’t have an OGG-capable player (e.g. Totem, Xine, Firefox or Google Chrome), then download vlc. I also suggest downloading the high-quality version of the film if you have a high-speed connection, as the photography is excellent.
