I just released version 0.2 (and 0.2.1, now with a NEWS file!) of JUGC, the unit conversion library generator. It allows you to specify a set of measuring units and translations in XML files and generate a conversion library from them, thus avoiding parsing a definition file at startup. The generator portion is still written in Java, but now in addition to Java, it can also generate Python code. There are small examples on the Examples wiki page. There isn't much documentation, but the example data files and tests should be clear enough.
I put up pgrok ("Project Grokking for Emacs"), a simple Elisp package for project settings and tools, on Launchpad. It's a tidied up version of a couple of things I've been using for ages, basically for loading project (a source tree) settings, functions or whatever you need from files that are looked up in your directory hierarchy. There are also two (at the moment) functions for locating stuff in your project with find and grep.
There are no releases yet, but it's just one file in the bzr branch hosted on Launchpad. I use GNU Emacs 23.0.60, no guarantees about any other Emacsen.
They keep on asking their listeners to plug them, so here goes. I've been listening to podcasts quite a bit lately, as I got a phone that can do them and my commute is too short to really concentrate on reading articles, and the best of the ones I regularly follow is Software Engineering Radio. There's a lot of backlog to go through and at least the interviews they've done with Joe Armstrong, Galen Hunt and Dave "not PragDave" Thomas have been really nice.
