Same as last time, I guess. It's a voxel building environment that uses irregular voxels (voxels with sloped faces). I've been working on fixing the bugs for a while now (and there are still a lot of them left).
Speaking of unconventional languages for web development, there's also Wt, for people who are used to building things using C++.
I found it surprisingly good and considering how little I know on how to use HTML/CSS/JS/PHP, the usual web stack, it would have taken me months or more to learn how to build an equivalent site using the standard stack (and then have to maintain it).
Of course, if you're already familiar with web development, that's the best way I guess, but for those who aren't and don't have the necessary time to learn, there are probably alternatives using languages they're familiar with.
I' working on a voxel building environment, but using irregular (Voronoi) voxels instead of the usual cubic grid ones. Still very much a work in progress:
To be honest, it's actually more of a game development log, but it's the closest thing I have to a personal website.
It's hosted on an old Linux PC at home.
