Apparently, at some point a few days ago, my server's primary partition developed some sort of subtle directory corruption which allowed pieces of files to randomly overwrite each other. As you might imagine, this is not a good thing. I'm still not entirely sure exactly when/why this happened, but it's made the last few days rather entirely unpleasant. I'm limping along now, but it definitely reminds me that it's time to stand up a separate box so that my primary workstation and my web/mail server aren't one and the same, and to invest in some sort of budget RAID solution. I am now going to get several, blissful hours of uninterrupted sleep.
Oh yeah, obviously, this nonsense is the reason I wasn't able to do a Drive-By yesterday (breaking my string of Saturdays.) This feature will return next week.
They took some of the Van Goghs, most of the jewels, and all of the Chivas!
