Random Geekery

Backing up just got a lot faster when I realized that copying a 12Gb file from an IDE disk to a USB 2.0 disk should *not* take 3+ hours. After some hints from the members of LUGOR, I discovered that last time I’d unplugged the USB disk for some reason, it had come back up as USB 1.1 “full” speed instead of USB 2.0 “high” speed, i.e. 12Mbps instead of 480Mbps. I replugged it and watched for the words “high speed” in /var/log/messages:

On the Powerbook front, I’ve been playing around a bit with a program called “Quicksilver” that a few friends have been raving about. You’d think this would be right up my alley, since it allows me to control my computer with more keyboard interaction and less mousing. But so far, my reaction has been “meh”. It can do some cool stuff, but it’s a memory hog. I never thought I’d see the day when 1Gb of RAM in a laptop was barely adequate, but thanks to Firefox and Quicksilver, I’m there.

In other Powerbook news, I’m anxiously awaiting my replacement power supply. I tripped over the one that came with it and had to order a new one on Tuesday, and it still hasn’t come. Damn good thing I bought a spare power supply back when it seemed that Apple had never heard of “strain relief” and their power supplies kept dying with arcing from worn out insulation where-ever a wire went into a solid piece, or I would have had a dead Powerbook for 4 days now.

Speaking of inadequate memory – does anybody make 1Gb SO-DIMM PC-133? Vicki’s iBook has 128Mb built in and one SO-DIMM slot, which currently has 512Mb in it. I know, 640Mb should be enough for anybody, but she’s had to give up on Firefox because it’s such a memory hog and she misses some of her plugins. (Shut up, Jason.)
