Storing Data in Control Flow
A decision that arises over and over when designing concurrent programs is whether to represent program state in control flow or as data. This post is about what that decision means and how to approach it. Done well, taking program state stored in data and storing it instead in control flow can make programs much…

How many engineers does it take to make subscripting work?
The select part is actually fine. But for updates, especially for complex updates, it could be pretty verbose and far from being ergonomic. What would you say to this syntax instead?

Compiler Performance and LLVM
I have always wanted the Cone compiler to be fast. Faster build times make it easier and more pleasant for the programmer to iterate and experiment quickly. Compilers built for speed, such as Turbo Pascal, D and Go, win praise and loyalty. Languages that struggle more with this, like C++ or Rust, get regular…

(1) Keep it simple, (2) make it something you'd actually use, (3) iterate.
It's not about technology for its own sake. It's about being able to implement your ideas.

Visualizing Diffs: The Myers difference algorithm (2020)
In 1986, Eugene Myers published An O(ND) Difference Algorithm and Its Variations , which unified the problems of finding the longest common subsequence of two sequences (the LCS of "driftwood" and "artwork" is "two") and finding the shortest edit script for transforming one sequence into another. Myers showed that…
