I used to do a lot of work in Ada :
Ada Lovelace :
world's first
programmer. I'm quite used to writing software in Ada :-) A lovely language, free
compilers are here. Expert
discussion is on the newsgroup comp.lang.ada.
For fun I converted Ada in Action ( local link | European mirror ) to hypertext from plain ASCII. The book had been released to the net by the author, Do-While Jones, so I thought the net could give something back... and in turn another Ada fan Dirk Craeynest found the web space to host it. I enjoy this kind of distributed cooperation :-)
A friend of mine and I collaborated on a multi-tasking Mandelbrot solver written in Ada, I have the source code but I haven't built it in a long, long time. I intend to make it work again and then I'll post it here on my server. Note, far from being a fast plotter, it's actually incredibly slow, because it does all its arithmetic in double precision floats, however we (the authors) found the structure of the code and the algorithm it uses to color points "interesting". I'm sure we could prevent people getting the wrong idea by calling it XAdaMandelbrotMultiTaskingCPUBurn2000 or something like that, but I doubt anyone will be interested anyway.
These days I mostly work in C++ cause there are better jobs available that way. But I still don't like it much.
