Technology failed me today. I was happily pounding away on Chapter 5, when my laptop died, abruptly.
I searched for the source, and realized I had a pillow sitting on top of my power supply, and it overheated. I'm hoping and praying that it didn't destroy the AC adapter completely, nor destroy my progress.
I'm a stickler for backups, so if I do lose work, it'll only be about a chapter's worth (I generally backup up to disk every two chapters or so.
Ah, the hazards of working on an ancient IBM thinkpad.
EDIT: Good news! It was just a simple overheat. After some fiddling, we got it back. Then the floppy drive jammed, inciting another panic attack, but that was just a random broken bit of laptop that had gotten ramming in there at an odd angle.
