A bad citizen in Javaland (2006)
You are born with no body parts. One by one, your organs are pushed into you. Should anyone attempt to interact with you before your organs have finished arriving you will die. Luckily this doesn&#…

Towards Tactic Metaprogramming in Haskell
Isn’t it weird that we treat source code as text? That is, we have this extremely well-structured and strongly-typed object — the abstract syntax tree — that exists conceptually in our minds, and in actuality inside of our compiler, but for some reason we pretend it’s just a pile of bytes and edit it byte-by-byte…

How the OCaml type checker works (2022)
A short guide on OCaml type checker, describing the surprisingly elegant algorithm for generalization, which generalizes to first-class polymorphism, MLF and local types. Polymorphism and regions have much in common.

Proposal for a Friendly Dialect of C
What implications exist around linking friendly-c code with machiavellian-c? I.e. put the performance critical kernels in there own module and work realy hard to make it correct.

Rust's Block Pattern
Here’s a little idiom that I haven’t really seen discussed anywhere, that I think makes Rust code much cleaner and more robust.

Lumo – A fast, standalone ClojureScript REPL that runs on Node.js and V8
One common complaint of Clojure REPLs is their [startup time](http://puredanger.github.io/tech.puredanger.com/2013/12/01/clj-problems/). Although that complaint is often somewhat unfounded (and related to tooling), it still takes the bare Clojure JAR about 1 second to start on new hardware…

Go modules have a v2+ problem
Go has a problem. Go modules place a strange naming requirement on modules version 2 or greater. Module names on modules v2+ must end in the major version ala …/v2 , and communication of this rule has been weak. It's non-obvious, and the community at large does not understand it.

Baby's First Garbage Collector
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.

A programming language from scratch: 3 steps to an interpreter
A little while ago I wrote about 16bitjs, a 16 bit virtual machine written in javascript. It implemented a custom CPU architecture and assembly language, assembler, and debugger. I had the thought …

C23: A Slightly Better C
One of the established and most popular programming languages is the C programming language. It is relatively easy to learn, and highly practical. Maybe surprisingly, the C programming language keeps evolving, slowly and carefully. If you have GCC 13 or LLVM (Clang) 16, you already have a compiler with some of the…

Ruby 3.0 and the new FiberScheduler interface
A few days ago on Christmas day 2020, Matz released Ruby 3.0. Like every year, a host of interesting new features was included with the new version. Most articles I have read so far focus more on the new ways to introduce type hints and the Ractor system but for me the most interesting addition was the introduction of…

A four year plan for async Rust
Four years ago today, the Rust async/await feature was released in version 1.39.0. The announcement post says that “this work has been a long time in development – the key ideas for zero-cost futures, for example, were first proposed by Aaron Turon and Alex Crichton in 2016”. It’s now been longer since the release of…
