In *nix parlance, random and urandom are virtual devices providing sources of random data. While random makes the user wait for high quality data, urandom just hands over whatever data is at hand -- even if the quality is poor -- in the hopes that it will be good enough to be useful as long as it is timely.
In the spirit of urandom, I went spelunking through my personal source code repository for things that never got to release quality (or even completed, in some cases) or just didn't seem general enough to publicize, but which may be of use to someone nevertheless. Most of them were used for a short period and then forgotten, though a few I use regularly for personal projects but never put in the extra effort to spit shine and release. Very few have traditional test libraries or install scripts or similar helpful niceties. Heck, I had to add copyright notices to most of them before uploading them here . . . .
