BoingBoing is a craptastic flood of news of the weird and IP/telecom/computing policy. Every now and then a really useful nugget floats by.
Mark Frauenfelder recently pointed out the current top 10 torrents on publicdomaintorrents.com. I didn't realize that stuff like "Night of the Living Dead", and "Plan 9 From Outer Space", are in the public domain. What's the big deal about these films, at least from my perspective? Well, bits and pieces could probably be quite humorously applied to lectures and presentations.
C'mon, you just know there's gotta be a way to use a drop from "Night of the Living Dead" for that lecture on UNIX zombies. ;-)
