I set up a SourceForge project for vmips, but unfortunately, it doesn't look like SourceForge has much to offer beyond what I have set up at home, with the possible exception of a bug tracking system (and it's not like those are hard to set up) and more bandwidth (which might be useful later, but not now.) So I am just mirroring my web pages there for the moment.
In terms of actual free software work, the only thing I've done lately is work on the embryonic vmips manual. I also made a new release of WebNews on March 15th, with better article sorting support, e-mail carbon copy of posted articles, and more bug fixes. I will probably mirror WebNews's site onto sourceforge eventually as well.
The more I use C++, the more I find I like it. And, speaking of C++, I still like GCC 3.0, which I am actually using on a daily basis now (especially because it has libstdc++-v3 inside(tm)). I wrote a little web page about how to play with GCC 3.0. I highly suggest you try it.
