Imperfect machine

Physical therapy this morning was really interesting. I've never actually been to PT before. I found out a lot about all the ways I'm asymmetrical: ( know thyself... know they flaws. )

I haven't talked much about my hardware studies, but I mentioned we're revving up for a book club at work in which we'll study how computers are built, from logic gates on up to compilers. I never studied this in college, so I'm reading quickly through a lighter book that covers a lot of the same material, in an attempt to be hitting the concepts for the second time in the book club. So, for the first time I understand why regular, static RAM requires power in order to retain its memory... some types like DRAM are even flakier, having to be refreshed often or the stored memory just fades out. And I wonder if human memory has anything in common with that. If so, all the cryo people are wrong, and it won't ever be possible to freeze a person and bring them back, because the electrical power in the brain will have been cut in the meantime, and all our little transistors / relays / quantum doohickeys will have reverted to their base state.

Memory is a spooky thing.

Invidious tumbling post

This evening I went to gymnastics, and they strapped me into a harness on the trampoline to hold up part of my weight, and I did front and back handsprings (front ones without a spot, even) and it was grand. More, please!
