Wandering through the technical landscape

I am a hobbyist and professional programming language designer and compiler writer. I currently am paid to work on FOSS by SlamData.

Starting Fresh
02 Mar 2012
Yet another attempt to get me back to blogging about code. It’s been a while, but I have a few posts queued up, so we’ll see if I can rebuild the habit. If you’re interested in my old stuff, it’s still available at my site (although much of it has...
