The machine on which this blog is run is having some technical trouble and needs to have a couple of bits replaced. (Literally, though I suppose it’s really just one: Somewhere in its gigabyte of memory, there is a single bit that won’t turn on, but this still warrants replacing the memory chip. Also, the hard drive is failing I think.) So, the blog might be missing occasionally over the next couple of days, but after that it should return to normal.
