What is a Distant Pocket?

Salutem plurimam.

Thinking, speaking and writing about math and science is a joy of mine. I hope to explore the ‘hows and whys’ of some interesting computational issues.

I’ve written a few small utilities which I’ll post (and discuss) the source code to. Also, I expect the chronological dimension will serve as an excellent viewport for in-progress projects.

Ground rules:

As a game developer, I’m under numerous NDAs. Often, I will only be able to address an issue tangentially.

Finally, sincere thanks to Blogger for hosting this!
