Playing like a kid again

In some of the communities I hang around in1, there’s a fondness for the kind of industrial research that happened at places like PARC and Bell Labs. Things like Smalltalk, Mesa/Cedar, and Plan 9 not only introduced new ideas but demonstrated them in practical, working systems. If you want to actually do research like this, how should you go...

I got to work on some great teams, learned a ton, and had a lot of fun. Corel My first real internship was on the Linux team at Corel in the summer of 2000. I was super excited about this, for a...

But over the past year, I’ve started taking learning seriously in a way that I never did before — at least outside of a formal academic setting. Earlier in my career, learning was basically a given: almost any interesting project I could take on would involve diving into things I was...

Most people probably associate bytecode VMs with general-purpose programming languages, like JavaScript or Python. But sometimes they appear in surprising places! Here are a few that I know about. eBPF Did you know that...

And then I saw the paper AST vs. Bytecode: Interpreters in the Age of Meta-Compilation” when Stefan Marr shared a draft on Twitter. I realized that although I’d written a number of tree-walking...
