Dammit. Having made all my wonderful fixes and upgrades to the mythbox, the “new” fan proves itself not up to the job. So now I have a desk fan pointing into the open case on my floor whenever I need to use it. Not very good, is it?
Also, whilst adding a new table to the database, I cleaned up the comments table (and some other bits and pieces), but forgot to reset the comment counts (they’re stored with each entry rather than generated to reduce the number of queries each page makes). Blast again!
