LSP: The good, the bad, and the ugly
For a few years now I have been working on the Haskell Language Server (HLS), and the lsp library for the LSP protocol and writing LSP servers. Unsurprisingly, I have developed some opinions about the design of the LSP! Recently I gave a talk about HLS and LSP at the Haskell Ecosystem Workshop at Zurihac 2024. One…

Why bother with argv[0]?
The first argument of a program’s command line, typically reflecting the program’s name/path and often referred to as argv[0], can in most cases be set to an arbitrary value without affecting the process’ flow. Making the case against argv[0], this post demonstrates how it can be used to deceive security analysts…

Understanding the Y Combinator
This article is about the Y combinator, a fixed-point combinator that provides a way of using recursion in scenarios and programming languages where symbols are not available. The concept of the Y combinator itself is closely related to lambda calculus (λ-calculus) and functional programming languages. More…

My Blog Engine Is the Erlang Build Tool
From time to time, people ask me what I use to power my blog, maybe because they like the minimalist form it has. I tell them it’s a bad idea and that I use the Erlang compiler infrastructure for it, and they agree to look elsewhere.

OAuth from First Principles
I've wanted to write a blog post for everyone who learns things the same way that I do; by trying to break them. I'll start off with an awfully flawed implementation that authorizes a user with a 3...

A Real Life Off-by-One Error
The Championnats d’Europe d’Escalade (climbing) in Villars-sur-Ollon has just finished. I couldn’t make it to all the events, but did see the finals of the “Speed” event. It’s a series of head-to-head elimination races up a 15m tall wall, resulting in an eventual victor after enough rounds.

Honey, I shrunk {fmt}: bringing binary size to 14k and ditching the C++ runtime
The {fmt} formatting library is known for its small binary footprint, often producing code that is several times smaller per function call compared to alternatives like IOStreams, Boost Format, or, somewhat ironically, tinyformat. This is mainly achieved through careful application of type erasure on various levels…

500 Python Interpreters
As we approach the final release date for Python 3.13, I’ve seen an uptick in discussion regarding 3.13’s introduction of an optional GIL. While removing the GIL has been a long time coming for the average user (I’ve dreamt of this for nearly 20 years), there have actually been two concurrent efforts to improve…

Rust's Ugly Syntax (2023)
People complain about Rust syntax. I think that most of the time when people think they have an issue with Rust's syntax, they actually object to Rust's semantics. In this slightly whimsical post, I'll try to disentangle the two.
