Over my lunch hour, I've started taking about 15-30 minutes of my day and going through the list of newly filed bugs, marking duplicate reports or applying the stock NEEDINFO responses for bug reports without good stacktraces. I can't do any in-depth triaging, since I'm at work away from my development environment, but I figure that I can at least help cut down on some of the noise in bugzilla with only a little bit of effort every day.
I've been using and developing software on Linux for a little while now, but I've always felt slightly uneasy about my lack of detailed knowledge about the Linux kernel. So I picked up rlove's kernel development book this past weekend and I'm about halfway through it already. I'm gradually beginning to feel more ... what's the opposite of uneasy? easy? at ease? Anyway, it's quite good and well written. Highly recommended if you're looking for a nice introduction to the Linux kernel.
Nemiver's proceeding nicely to a 0.2 release which should be a lot more robust in a lot of ways, including better support for poorly-behaved versions of gdb.
