There is a new release of the deskbar calculator available. There are no new features, but now works with python 2.5 and a nasty hack that fiddled with deskbar’s internals has been removed thanks to advice from Jason LeBrun.
For those of you that came in late: The deskbar-calculator is a plug-in for the deskbar applet that allows you to use it as a simple calculator. You just type your equation into the deskbar entry-box and the answer is displayed in the drop-down list, just like a search result would. It isn’t very powerful, but it is very convenient.
