Various things I've done have been recorded. Frightening thought, isn't it?
Intro to Embedded Systems, a talk Garrett Kajmowicz and I gave at Penguicon 5. (local mirror).
Back when I worked at timesys, they Interviewed me for a podcast they did. (local mirror) Sheer convenience, I worked down the hall from their recording booth.
I dump liquid nitrogen into the hotel swimming pool at Penguicon 4. (Here's a local copy at higher resolution.) The ice cream ingredients ran out before before the liquid nitrogen did, so Sunday afternoon we played with the remaining stuff, freezing things in it, dipping towels in it so "fog girl" could run through the halls, etc. After I dumped a bowl in the hot tub and got much fog, Howard Tayler (of Schlock Mercenary) got his video camera while I filled the biggest bowl we had to dump it in the pool. (And _this_ is why a convention likes to fill up the entire hotel and "own" it for the weekend. Just sayin'.) Howard's the one providing narration, and the woman who jumps in is Molly DeBlanc, she's the blonde in the green coat leaning against the wall near the beginning. (I think somebody offered her $20 to do so.)
Will it blend - Liquid Nitrogen Ice Cream (Spoiler: the answer was "no". On the bright side, how often do you get to say "But at least we caught it on video!") Mark and myself attempted to make mango ice cream in a blendtec blender (yeah, the one they blend iPhones with). Mark had previously put LN2 in an empty blender, so we knew the blender itself could handle it. What we didn't take into account is that the escaping plume of steam would be taking ice cream with it this time. No, this was not a special effect, we actually did this, and spent the next half hour cleaning up before briefly airborne milk-based products could soak into Mark's entire apartment. (It made it into the bathroom and bedroom. His computer was right behind the camera, and the router was positively covered. So was the refrigerator behind us. The bit you can't quite hear is Fade asking "what just hit my arm?", and she was over in the living room at the time...)
Populating initramfs with busybox and uClibc (local mirror), a tutorial I gave at OLS 2006. - These days I'd point people at my cross compilers instead of the timesys ones, and probably use qemu instead of User Mode Linux.
In theory my OLS 2007 talk on cross compiling was recorded, but they never gave me a copy.
2008 OLS compiler BOF I hosted. (local mirror) I expected to talk for about 3 minutes then shut up and listen. Turns out I suck at that. (I even moved away from the front of the room at one point, but people kept asking me questions.)
BusyBox state of the union 2006, a talk I gave at CELF. Keep in mind that I'd been awake _all_night_, my plane got in to chicago after the connecting flight left, and I had them send me on to California so I could get a red eye in the morning to make it to my talk rather than taking the hotel room the airline offered me in Chicago (from which even the red eye couldn't have gotten me to San Jose in time for my talk; 3 hours flight plus 2 time zone changes, plus getting there from the airport. I barely made it to my talk with an early morning flight from LA to San Jose). Sleeping on the floor of the Los Angeles airport doesn't really work, so this is what I sound like truly massively sleep deprived. (And caffienated, but that goes without saying.)
Note to self: dig up Linucon recordings
