Why F# evangelism isn't working (2015)

If you skim this blog entry too quickly or just read the title, you might think I am someone who does not like F#. Nothing could be further from the truth. Over the last several months, I have become a big F# fan. It has become my preferred language for personal projects.

Clojure Plays Mario

Before getting too far into the weeds, let's begin with the results. Without too much effort, an AI was written in clojure that could complete all of the levels in the original Super Mario Bros for the NES except for the Bowser levels that have mazes.

WTF is going on with R7RS Large?

The reaction to John Cowan’s resignation as chair of the R 7 RS Large working group has been somewhat wider than I think anyone expected, making it onto general interest programming forums. Scheme may be a small island, but when it has an earthquake, it makes waves through the whole archipelago of programming…

I wrote a string type

I write compilers for fun. I can’t help it. Consequently, I also write a lot of parsers. In systems programming, it’s usually a good idea to try to share memory rather than reuse it, so as such my AST types tend to look like this.
