I presented my paper on "The Challenges of Integrating the Unix and Mac OS Environments" at USENIX on Thursday morning. The session went really well. It was well-attended, and I fielded about half an hour of questions afterward. The general feeling I got at the conference was that many people in the Unix community are excited about the potential of Mac OS X.
Wednesday night was the "Night of the Living BSDs"; there were back-to-back Birds-of-a-Feather sessions for NetBSD, OpenBSD, FreeBSD, and BSDi, followed by a BSD coctail party. I met up with a bunch up people there, and it was a fun night. Jordan gave Mac OS X a nice plug at the beginning of the FreeBSD BoF.
Right after my talk, I flew to Detroit for Mac Hack, which I'll at now. This year's Mac Hack is packed with lots of sessions, and there is a lot of Mac OS X hacking this year. I'm taking the DropScript demo I whipped up for WWDC and wiring up a pack/unpack tool pair called "ShoveIt Deluxe". Pretty wimpy, really, but I only had one day instead of two, and I wanted to go to some sessions and see what everyone else is doing this year. I also ran into someone who was looking to hack up SystemStarter to display marching icons at the bottom of the screen as done in Classic Mac OS. It turns out he was asking about it nearby, and I overheard him mention some problems he was having (we don't public all of the API he needs yet), so I let him know I wrote SystemStarter and helped him out with it. I love Mac Hack; this stuff is just fun.
Josh and David and I spent some time in the past couple of weeks rewriting the hack we did last year, "Shagadellic Telly". Josh and Dave bough a "WinTV" TV tuner card and figure we could fix the "Win" bug in the name by writing a Mac OS X driver. We have a much cleaner driver this time. I wrote the Cocoa application (the Telly) which controls the driver and tells it where to blast onto the screen. This version, though still incomplete, works rather well, and has a bunch of neat features. The driver and app are in the "AppleBt8xx" driver project in Darwin, if you're ihterested in playing with it.
