Until recently, my vhost was running some ancient Ubuntu that was probably vulnerable to all manner of things, so I’ve finally upgraded it to a recent Debian release. A few things are still offline (including the blog theme) so there may be some broken links here and there for a few days until I get around to restoring everything.
I believe I’m going to leave comments off permanently going forward, there’s just too much spam even with it moderated, to the extent that I almost never bother to go through them. Comments out-of-band are always welcome, of course.
