We had a disk failure, & had to restore from backup. Astute readers may notice that we’ve lost a few days’ worth of posts.
Not sure if we’ll be able to do anything about that (I’m on the road for the next few days. . .). In the meantime, wetmechanics are welcome to repost from their own personal archives, if they care to do so. . .
We apologize for the horrible discontinuity.
