1. sptool is a quick way to compare standards to stellar spectra. Nice, I'd been looking for a tool like that. 2. GNU screen captions are useful especially when working in a screen-within-a-screen environment (who does that, really?) 3. finally got SPLAT to work... turns out I just hadn't reduced my damned data 4. kill -STOP and kill -CONT are really useful ways to pause programs that are sucking up resources if you want to resume them later. Haven't tried this on "real" code yet.
