04:47 AM Tom_L: show n tell
10:50 AM rue_bed: hmm a dream that I'm a robot, staggering at the edge of a parking lot in the bright summer sun, trying to find some shade. kneeling by the edge I ponder being nervous of the presence of a drug needle on the ground that presents no danger to me as I'm a machine.
11:06 AM Tom_L: shouldn't need shade, use your solar pannel to recharge
01:18 PM Tom_L: what was the command to raw write 0000 or 1111 to the boot sector to basically erase a disk?

10:40 PM rue_shop1: Tom_L, this pipe is small enough that getting into that crack if I use a piece of plate, doesn't look like it'll be an issue
