One of the reasons I write is to help me organize my own mind. I have a compulsive need to figure things out and I’ll lay awake at night shuffling sentences around in my head until it hangs together. Then I just have to try to get it all down in Markdown before it dissolves back into chaos.

It took three years and 200,000 words more than I expected, but my second book, Crafting Interpreters , is complete. I finished the third draft of the last chapter today, marking the last of around 1,400 days of continuous writing.
The hardest program I’ve ever written, once you strip out the whitespace, is 3,835 lines long. That handful of code took me almost a year to write. Granted, that doesn’t take into account the code that didn’t make it. The commit history shows that I deleted 20,704 lines of code over that time. Every surviving line has…
I don’t know about you, but nothing gets me going in the morning quite like a good old fashioned programming language rant. It stirs the blood to see someone skewer one of those “blub” languages the plebians use, muddling through their day with it between furtive visits to StackOverflow.
Several months ago I promised a follow-up to my previous blog post about turn-based game loops in my roguelike . Then I got completely sidetracked by self-publishing my book , Game Programming Patterns , and forgot all about it. I totally left you hanging.
Update 2014/04/28: In case you missed the link, the web site for my book is gameprogrammingpatterns.com .
My book Crafting Interpreters on programming languages is done. OK, OK. I know I said it was done like fifteen months ago . But now it’s really done. And by that I mean, the print, e-book and PDF versions are done. You can buy it . You can hold it in your hands. And I do mean “hands” plural. Because this little…
I got started hacking on my own roguelike after spending several years avidly playing Angband . Like most projects, I had a few itches I wanted to scratch and it kind of took on a life of its own. One thing that annoyed me about Angband was how monsters dropped loot when they died.
When I get stressed out and have too much to do, I have this paradoxical reaction where I escape from that by coming up with another thing to do. Usually it’s a tiny self-contained program that I can write and finish.
It seems like I can’t spend five minutes on reddit these days without someone playing the JS-is-Scheme is card . I see everything from the innocuous, “JavaScript has a lot in common with Scheme”, all the way up to, “JavaScript is basically Scheme.” This is basically crazy. Or, at least it has a lot in common with…
Every now and then, I stumble onto some algorithm or idea that’s so clever and such a perfect solution to a problem that I feel like I got smarter or gained a new superpower just by learning it. Heaps were one, just about the only thing I got out of my truncated CS education. I recently stumbled onto another: Pratt or…
One smart thing Google does is rigorous code reviews. Every change, before you can land it, gets reviewed in at least two ways. First, someone on the team does a normal review to make sure the code does what it’s supposed to.
I’ve been noodling on a static type system for my current hobby language. To try to keep the language as simple as possible, I’m trying to see if I can live without subtyping. Since most of my programming experience is in object-oriented languages, I’ve been learning more about languages that lack—or at least claim to…

Someone on StackOverflow stumbled onto the strange term “open recursion” and asked what it meant . Since most of the other answers to this online are pretty opaque, I started writing an answer. But then I accidentally wrote a blog post.
Magpie has reached a strange but neat little milestone on the road from “weird experiment” to “real language”: the type system is now bootstrapped. I’m not aware of any other languages where a statement like that is even meaningful (maybe Typed Scheme ?), much less true , so I’ll try to break that down.
