Migrating from Warp to Axum
Falling out of love with warp Back when I wrote this codebase, warp was the best / only alternative for something relatively high-level on top of hyper. I was never super fond of warp’s model — it’...

Summer of Programming Languages
Having just returned from the annual Oregon Programming Languages Summer School, at which I teach every year, I am once again very impressed with the impressive growth in the technical sophisticati…

Mutt on Windows Without WSL
I have this weird hobby of trying to get good unix tools to run natively on Windows. I find this is the most efficient use of my laptop's resources, and therefore the nicest experience. WSL is nice, but it takes up a lot of RAM on my system. I prefer to use MSYS2 . Getting unix tools to work correctly under MSYS2 is a…

URL query parameters and how laxness creates de facto requirements on the web
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

A rough proposal for sum types in Go (2018)
Sum types are pretty cool. Just like how a struct is basically “This contains one of these and one of these”, a sum type is “This contains one of …

Quote-unquote "macros"
You’ve probably seen this Python 101 thing before: @memoized def fib(n): if n <= 1: return n return fib(n - 1) + fib(n - 2) Leaving aside the absurdity of computing Fibonacci numbers recursively, it’s a common first introduction to Python decorators and higher-order functions. fib is just a function, and memoized…

JVM Anatomy Quark #26: Identity Hash Code
"JVM Anatomy Quarks" is the on-going mini-post series, where every post is describing some elementary piece of knowledge about JVM. The name underlines the fact that the single post cannot be taken in isolation, and most pieces described here are going to readily interact with each other.

Message Oriented Programming
Designing around the messages, rather than the objects, brought my whole system into focus. If modules communicate by passing around self-contained textual data, or a simple structured format like JSON, they impose fewer assumptions on each other.

What is “Open Recursion”?
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.

Building a language server for Muon
I’m a big fan of interactive tool support for programming. I often use features like “go to definition”, “find symbol”, compile error underlining, etc. Also, earlier this year, I launched Muon, a new low-level programming language. As no tooling existed beyond the compiler, writing the initial Muon programs (such as a…

Constexpr is a Platform (2020)
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution. In both cases you restrict yourself to the subset of C++ that works on your target platform, use conditional compilation if your code…

Can you figure out how this single part boost converter works?
If you think this is easy, then I think you are missing something. This is hard. You need to know your hardware intimately to figure this one out.
