Lightstorm: Minimalistic Ruby Compiler
Some time ago I was talking about an ahead-of-time Ruby compiler. We started the project with certain goals and hypotheses in mind, and while the original compiler is at nearly 90% completion, there are still those other 90% that needs to be done.

I wrote a Game Boy Advance game in Zig
The Game Boy Advance is an interesting game console. It has a modern-style CPU (32-bit ARM, lots of registers), but uses an old-fashioned tile based renderer like how the NES did it in the 80s. Don’t get me wrong, since its one of Nintendo’s last tile-based systems, they took the idea as far as it can go with fancy…

My long-time collaborator Richard Barnes [1] used to say that "in security, trust is a four letter word" , and yet the dominant experience of using any software-based system—which is, you know, pretty much anything electronic—is trusting the manufacturer. Not only is there no meaningful way to determine what software…

Debugging memory corruption: who the hell writes "2" into my stack? (2016)
Several weeks ago we received a bug report from a customer that said their game was crashing when using IL2CPP scripting backend. QA verified the bug and assigned it to me for fixing. The project was quite big (although far from the largest ones); it took 40 minutes to build on my machine. The instructions on the bug…
