This article was discussed on Hacker News. This is a continuation of my last post on how to write a tree-sitter grammar in an afternoon. Building on the grammar we wrote, now we’re going to write a linter for Imp, and it’s even easier! The final result clocks in less than 60 SLOC and can be found here. Recall that tree-sitter is an incremental parser generator. That is, you give it a description o
I see people make the same mistakes over and over again when learning Rust. Here are my thoughts (ordered by importance) on how you can ease the learning process. My goal is to help you save time and frustration. Let Your Guard Down Stop resisting. That’s the most important lesson. Accept that learning Rust requires adopting a completely different mental model than what you’re used to. There are a
Faster virtual machines: Speeding up programming language execution - Mort's Ramblings
Date: 2023-01-15 Git: https://gitlab.com/mort96/blog/blob/published/content/00000-home/00015-fast-interpreters.md In this post, I hope to explore how interpreters are often implemented, what a "virtual machine" means in this context, and how to make them faster. Note: This post will contain a lot of C source code. Most of it is fairly simple C which should be easy to follow, but some familiarity w
You might not have noticed, but a large portion of a programmer's day involves writing: code, comments, emails, messages — whether in Portuguese, English, Python, or JavaScript — we are constantly converting thoughts into characters. Or, as I prefer to see it, transforming abstractions into concrete actions. You could argue that comparing writing code to writing text (i.e., natural language) is pu
Tuesday, September 13, 2022 :: Tagged under: engineering. ⏰ 11 minutes. Hey! Thanks for reading! Just a reminder that I wrote this some years ago, and may have much more complicated feelings about this topic than I did when I wrote it. Happy to elaborate, feel free to reach out to me! 😄 🎵 The song for this post is I, Don Quixote from the musical Man of La Mancha, composed by Mitch Leigh and Joe
May 12, 2023 Hello! I’m excited to announce a project I’ve been working on for a long time: a free guide to implementing your own DNS resolver in a weekend. The whole thing is about 200 lines of Python, including implementing all of the binary DNS parsing from scratch. Here’s the link: This project is a fun way to learn: How to parse a binary network protocol like DNS How DNS works behind the scen
The components of an integration test. The testing infrastructure provides the foundation on top of which engineers write their tests, and the execution platform for running them. Enabling developers to prototype, test, and iterate on new features quickly is important to Facebook’s success. To do this effectively, it’s key to have a stable infrastructure that doesn’t introduce unnecessary friction
As part of my PhD studies, I’m working on a distributed task runtime called HyperQueue. Its goal is to provide an ergonomic and efficient way to execute task graphs on High-Performance Computing (HPC) distributed clusters, and one of its duties is to be able to spawn a large amount of Linux processes efficiently. HyperQueue is of course written in Rust1, and it uses the standard library’s Command

Posted by Leonardo Galler and Matteo Kimura on April 21, 2019 What are Sorting Algorithms? Sorting algorithms are ways to organize an array of items from smallest to largest. These algorithms can be used to organize messy data and make it easier to use. Furthermore, having an understanding of these algorithms and how they work is fundamental for a strong understanding of Computer Science which is
