One of the most remarkable things about the julia programming language, is how well the packages compose. You can almost always reuse someone else’s types or methods in your own software without issues. This is generally taken on a high level to be true of all programming languages because that is what a library is…
I have changed my mind about some topics big and small so far in my life. Today: the value of types for programming.
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
I've been using zig for ~4 months worth of side projects, including a toy text editor and an interpreter for a relational language . I've written ~10kloc.
Exploring JVM specification and trying to write a little code to interpret a Java class like a real JVM.
I recently wrote my first 4K intro in Rust and released it at the Nova 2020 where it took first place in the new school intro competition. W...
PHP 8.0 brings features like attributes, union types, and the JIT compiler. It has some important breaking changes, and improved performance.
I have a particular view of Python performance from my experience on the Pyston project, and since this view is somewhat nonstandard I wanted to take some time to explain it and give a motivating e…
A gentle and beginner friendly overview of Rust Ownership Rules
The impact of PHP 8 on my code
I've recently read an article criticizing Rust, and, while it made a bunch of good points, I didn't enjoy it --- it was an easy to argue with piece. In general, I feel that I can't recommend an article criticizing Rust. This is a shame --- confronting drawbacks is important, and debunking low effort/miss informed…
This is the story of the rise and fall of Lisp at the Jet Propulsion Lab as told from my personal (and highly biased) point of view. I am not writing in my official capacity as an employee of JPL, nor am I in any way representing the official position of JPL. (This will become rather obvious shortly.)
With cljfx and Java 14 it’s finally here
A recent tweet by a friend of mine noted how the public interest in the Scala programming language seems to have plateaued or waned, which matches my feeling of the latest trends and zeitgeist. This blog post will go into why I think that has happened, where Scala stands now, and what the future holds for the Scala…
Every now and then I like to think about topics that don't directly relate to my daily work. One of those topics has been parsers: back in January I wrote about byte-ordered stream parsing and how I think we can improve streaming parsing in Rust with a small set of API additions.
Both QBE and LLVM are compiler backends using an SSA representation. This document will explain why LLVM does not make QBE a redundant project. Obviously, everything following is biased, because written by me.
There’s a proposal to add Software Transactional Memory , or STM , to the Ruby programming language. This is part of a wider effort to add better support for concurrency and parallelism in Ruby, and in particular the idea of ractors . A concept has been proposed and implemented by Koichi Sasada.
PHP isn't the same old crappy language it was ten years ago
I've just released a new version of Idris 2 , which is a significant release in that it's the first one which is able to compile itself. Thus, it's the first one where we can really see how the performance of Idris 2 improves on the performance of Idris 1.
Explaining the different mental model Deno has about managing dependant code.

Introspectable and extensible IDEs with logic programming
I've been wanting to write a big project in Rust for a while as a learning exercise, and actually started one in late 2018 (a FUSE server implementation). But then life happened and I got busy and never went anywhere with it. Due to certain world circumstances I'm currently spending a lot of time indoors so rust-fuse…
It’s been just over two years since I started learning Rust. Since then, I’ve used it heavily at my day job, including work in the Firecracker code base, and a number of other projects. Rust is a great fit for the systems-level work I’ve been doing over the last few years: often performance- and density-sensitive…
