If you've been following along, SDL moved to GitHub earlier this year. This was a lot of work, and made me extremely nervous, but I have to be honest...it worked out really well.
Much of libsdl.org was built off of my admin work on icculus.org, which is to say my personal projects remain on almost identical crumbling infrastructure to what SDL fled from.
And all the whole-ass mood I generated about server administration for open source projects being exhausting continues to be true, but there's even less motivation to maintain them when they aren't crucial pieces of open source, like most of the things I've written and host on icculus.org.
There are currently fifty-nine Mercurial repositories on my server that are owned by me. Some of them are important, some are trivial, some are garbage, and some are things I did in high school in 1995 and just don't want to lose.
Some are super-important to my productivity and useful to exactly no one else. The fork of the text editor I use, the thing that archives my tweets. Some are goofy, like the little Gopher server. And there's one or two things that people really seem to like.
So these are moving on to GitHub. The migrations here are way less involved than SDL was, but even just tweaking all the settings across almost sixty repositories takes time, so these aren't all moving at once.
For now, it's just PhysicsFS, MojoShader, and SDL_sound. Others will be following later.
The various Mercurial URLs will continue to serve for now, before seeing final commits that delete everything but a README that says "this has moved to *here*," and eventually just vanishing outright. When visited by a web browser instead of a Mercurial client, we will forever attempt to redirect everything we can to the appropriate place (like this link to an arbitrary PhysicsFS commit at hg.icculus.org lands on the correct page on GitHub already).
My hope is that this effort takes some administrative and emotional load off of me, and also kickstarts a few of these projects that are already useful but currently only see frenzied bursts of activity from me every few years. If that's true, it was an upgrade no matter what tech underlies the development work.
