In this tutorial, we will learn about solving Differential Equations with Julia. Differential Equations are everywhere in Science and Engineering problems. And, being able to solve Differential Equations using computers is very convenient. We will use the DifferentialEquations.jl package for solving Differential…
wingolog: article: the last couple years in v8's garbage collector
Background On April 16, 2025, Apple released a patch for a bug in CoreAudio which they said was “Actively exploited in the wild.” This flew under the radar a bit. Epsilon’s blog has a great writeup of the other bug that was presumably exploited in this chain: a bug in RPAC. The only thing out there that I am aware of…
EDIT: Part 2 is up! It's a pedagogical pet peeve of mine when technical concepts are simply listed in their fully developed state, with little in the way of motivation, derivation, or historical context. This, I think, is like publishing a cookbook filled with beautiful pictures of cakes, but
In preparation for a future project, I was thinking about at the unix find utility . It operates a file system hierarchies, with basic operations selected and filtered using a specialized expression language. Users compose operations using unary and binary operators, grouping with parentheses for precedence. find may…
There are several aspects of Rust that I’m not particularly fond of but the one that takes the cake is core::io::BorrowedBuf which I despise with passion. It’s a nightly feature which puts in question my extreme emotions about it. On the other hand it means there’s time to stop it from getting stabilised and figure…
It’s been nearly four years since I published Parsing Protobuf at 2+GB/s: HowI Learned To Love Tail Calls inC.In that article, I presented a technique I co-d...
It is a somewhat common question to me: how do we write C in curl to make it safe and secure for billions of installations? Some precautions we take and decisions we make. There is no silver bullet, just guidelines. As I think you can see for yourself below they are also neither strange nor … Continue reading Writing…
This new edition has been the occasion to overhaul the presentation in many places, but its main purpose is the update to the new C standard, C23 . The goal was to publish this new edition of Modern C at the same time as the new C standard goes through the procedure of ISO publication. The closest approximation of the…
Typst's math mode has a strange precedence problem that most people using it will run into at some point.
Ultrassembler is a superfast and complete RISC-V assembler library that I'm writing as a component of the bigger Chata signal processing project.
Last year, I discovered that the Kosinski compression format is actually LZEXE, which was used for compressing DOS executables back in the 90s and the late 80s. Its developer catalogues three versi…
(This is the blog post version of my keynote from EuroPython 2025 in Prague, Czechia.) We now have a lock file format specification. That might not sound like a big deal, but for me it took 4 years of active work to get us that specification. Part education, part therapy,

Random tech notes
I like CPU architectures, especially weird, interesting and unusual ones. For example, the Intel iAPX 432 is still something I would love to play around with. Recently, I realized that a working CPU can be made with just a simple Move instruction. For this to work, everything needs to be memory mapped. The ALU…
Why you should write more toy programs
A few years ago I blogged about custom tree-sitter-based syntax highlighting in emacs . I started out with highlighting certain keywords in...

So you don't have to.
Someone online was solving Advent of Code problems, and had a question about last years’ day 3 . They had a working solution using regular expressions (regexes) on String values, but they wanted to use ByteString values instead for performance reasons. They were surprised, however, that there seems to be a lack of…
Why clear communication—not clever prompts—is your real AI superpower
This is a contribution to the Emacs Carnival 2025-06: Take Two collection of posts on Christian Tietze’s blog. My first take with Eshell many years back did not leave a good impression. My...
Neologisms for the current computing era.
While my final ranking in the Google AI Contest was disappointing ( 280th ), it was a very educational experience and was totally offset by Gábor Melis' dominating win using Common Lisp as well.
I always assumed that Python's str.splitlines() split strings by " universal newlines ", i.e., \n , \r , and \r\n .
How local, learnable routers can reduce token overhead, lower costs, and bring structure back to agentic workflows.
