Omigod. It's warm outside. The sun is out. Maybe it's even hot outside. w0000t f0r weathar!
Ordered more RAM for my workstation. I figured out why my user-mode-linux was going so slow: all the virtual memory is created in files that live in /tmp. My root filesystem is on a fast disk... but not that fast. The idea is that you're supposed to mount /tmp as tmpfs, which is basically a dynamic ramdisk. But ephemeral filesystems scare the hell out of me. Fortunately, UML supports an environment variable saying where to put the temp files, so now they live in a separate tmpfs. It's actually a pretty neat idea to keep the memory in files... that way you can test how linux copes with 512GB of memory while only using 512GB of disk! :D
And now that I've got my work schedule.. worked out.. I can get to.. work on it.
