"I usually decline to participate in "open source" or "Linux" events. See http://www.gnu.org/gnu/gnu-linux-faq.html for why it is incorrect to refer to the operating system as "Linux"." Ah, this never gets old. Also, using Pepsi to keep awake. Are all riders this god damn picky? It wouldn't surprise me. I imagine there is a great amount of antagonism between performers/speakers/etc and the venues.
I've never read GNU's Linux FAQ that I can remember, but this section is interesting in light of the GNU kernel's history: Question: Isn't writing the kernel most of the work in an operating system? Answer: No, many components take a lot of work. If I recall correctly, work on the GNU kernel began in the mid-80's (HURD in 1990?). I'll leave the correlation to the reader.
Sure, if enough folks wanted to, they good finish Hurd. But what's the point? They should go work on Linux.
