The Null Device is back; there was a technical problem with the
machine hosting it, and so it was down for 2 days, but now it's back.
As you may notice, the past few days' worth of blog entries have been uploaded
(apart from trivial things which everybody else is likely to have blogged).
Anyway, if this site mysteriously goes offline for a prolonged period again,
a backup blog-in-exile will resume
here until "normality" can be restored.)
