Judging from the clouds and wind that I see out the window right now, I think we probably finished the run just in the nick of time.
You'd think I would have learned by now to stop doing this. Only about 1 in 1000 newsletters are actually worth reading, I've found. But anyway, to make a short story long (which is the whole point of blogging), this evening I sat down and finally read an Apple Developer Connection newsletter that was annoying me in my inbox. It turned out that it was pretty interesting and a lot of fun. It kind of made me wish I could still just program for fun (and not also worry about getting paid).
The article I was reading was about loadable kernel modules (LKMs), which Apple apparently calls kernel extension modules, or KEXTs, for short. You can find the article here. It's really straightforward and clearly written, which is not common for kernel related documentation. Now I'm trying to think of what I would write a KEXT for. Too bad I was able to find a driver for my USB-to-Serial cable. That would have been a good candidate.
