Glad you like it. We don't do anything special, really. It's mostly just FreeType doing the rendering, and HarfBuzz doing the text layout. Hinting is turned off by default, though, as we find that looks a lot better once you get to 200dpi. A 2012 Nexus 7 is now considered a fairly low resolution device, even though its 216 dpi would be pretty amazing on a desktop.

The new CFF renderer that's now open sourced and part of FreeType should make the rendering of CFF fonts a lot better.

I took college classes from 9 to 13, then my parents pulled me out entirely. There were good and bad aspects to my path. At 13, actual graduate math classes were a bit over my head, and I felt a lot of pressure and feelings of failure because I couldn't quite hack them. Also, being isolated was hard, and it wasn't until I came back to grad school at 22 that I felt I developed my social skills properly. But being allowed to focus on intellectual pursuits was really nice in a way, and I actually look back on that fondly. Now I have my PhD and work for Google, and I do geeky things for fun. As one example, I'm noodling on keyboards, and, being me, I'm writing a DX7 synthesizer emulator. Most people consider the math of it to be impenetrably difficult, but, I'm like, "oh, _Bessel_ functions, I can dig that shit!"

I hope he does well and finds a path that makes him happy. One thing my parents did was keep me out of the newspapers (and off the front page of Slashdot, although we didn't have that then). I'm not sure whether that was entirely good or bad - publicity is valuable coin in today's society :)

As you can see from my uid, I've been with you since almost the beginning. At times I've been frustrated with the quality of the posts, especially the pseudoscience garbage, but /. has always been one of my go-to places, and always enough interesting content to make it worthwhile to visit. Plus, the format of the site, especially the moderation system, has proved to have enduring worth, even with all the other changes going on. I wish you the best of success in whatever you choose to do next.

I did a couple of things like this back in the mid-90's. One used iterated fractals. I think the original idea was by Ian Goldberg, and I added the coloring.

But I wasn't satisified by the fact that lots of different hash values produced similar-looking images, so I also cooked up one that had a guarantee that a single-bit change in the hash led to at least a single-bit difference in the image, and came up with these snowflakes:

Could be this is a better and slicker implementation than any of this stuff, but the underlying ideas are not quite new.
