Netspeed is a GNOME panel applet that shows your current upload/download speed in bytes (or bits) per second. I love it. Except... you have to manually say which network device to monitor. If you're switching between wireless and wired, this gets old really quickly. There's an option, Always monitor a connected device, but it is buggy and usually gets stuck monitoring some stupid network interface like wmaster0 or vmnet8.
While doing this I created a local Bazaar branch for playing with the source code. Sadly, Bazaar decided to hurt me again: bzr viz, instead of letting me look at my commits in a nice GUI window, barfs AttributeError: 'KnitPackRepository' object has no attribute 'get_revision_graph' and stops. Apparently the latest version of bzr-gtk (trunk from launchpad) is not compatible with the latest version of bzr (1.6rc2 from the Hardy PPA).
It's becoming a pattern: every couple of months I give Bazaar a try, and I hit a new bug that prevents me from doing whatever I wanted to do. Why do I even keep trying?
