In order to speed up development, as well as make sure gccrs exposes the exact same behavior as rustc in critical compiler passes, we decided last year to start reusing components and crates from the official Rust compiler where possible. These components range from external crates used for certain nightly options to…
wrenfold is a framework for converting symbolic mathematical expressions (written in Python) into generated numerical code in other languages (C++, Rust, Python). It aims to bridge the gap between prototyping of functions in expressive symbolic form, and performant production code. wrenfold is particularly relevant to…
I am a front-end developer who is FED up about front-end development. If you write front-end, this isn't about you personally. It's about how your choices make me angry. Also this is about how my choices have made me angry. Also this is mostly just about choices, the technologies are incidental. Note: The views…
chordcat is a chord-naming application and a pet project of mine. It is written in C++ and SFML.
Explore 3 limitations of using frame pointers for stack unwinding and profiling in Linux that are often overlooked, plus possible future alternatives.
I’ve noticed a small but interesting trend in the programming languages space. I’m not sure how novel it is, but this pattern, which I’ll refer to as “biphasic programming,” is characterized by languages and frameworks that enable identical syntax to express computations executed in two distinct phases or environments…
A guy decides to show off his Neovim setup.
Successful software is buggy software.
Rust compilation times is an ongoing topic that generates many discussions online1. Most people don’t really care about what exactly takes time when compiling Rust program; they just want it to be faster in general. But sometimes, you can see people pointing fingers at specific culprits, like LLVM or the borrow…
This will be the first in a series of posts describing different design decisions made writing two Rust crates:
After almost two years of work, we are happy to announce the release of Xfce 4.20.
In my last post I've described how to use Z3 to find simple local peephole optimization patterns for the integer operations in PyPy's JIT. An example is int_and(x, 0) -> 0. In this post I want to scal
After writing my thoughts on github3.py down here, someone was asking about Python libraries that people recommend new Python developers read for learning how to structure code and use the packaging systems. My initial reaction was "Don't listen to folks that tell you to read python-requests as a good example." When…
This is a really neat pattern. Start your Python script like this: #!/usr/bin/env -S uv run # /// script # requires-python = ">=3.12" # dependencies = [ # "flask==3.*", # …
So I was working on improving a DOS emulator, when I found that something seemingly trivial wasn’t working right when COMMAND.COM was asked to do the following:
Collection of side projects, conference talks and blog posts experimenting with frontend technologies and human-computer interaction
This post is dedicated to the memory of Niklaus Wirth, a computing pioneer who passed away January 1st. In 1995 he wrote an influential article called “A Plea for Lean Software”, and in what follows, I try to make the same case nearly 30 years later, updated for today’s computing horrors. The really short version: the…
You can come to McDonalds and order a salad, but you won't. Same with notebooks, you can write NASA-production-grade software in a notebook, but most likely you won't. Notebooks make you lazy, and encourage bad practices.
When writing code, you can call any function as long as it’s public, and similarly, you can access any object’s public properties or methods. Usually, access to code is all or none – a piece of code can be either public or private. Lately, I’ve been thinking about ways to implement more fine-grained access controls…

This update mostly focuses on further bugfixes over actually implementing new stuff, but we have quite a bunch of both!
tl;dr: I made ViHN to read Hacker News without having to move my hands away from the keyboard. It’s freely available on Firefox and Chrome. This is about yet another Hacker News extension. But other people with my obsession for killing the mouse might enjoy it. Most of the content of this article is just […]
A look ahead at some ongoing projects in PostgreSQL in 2024 and beyond
I do a lot of electronics projects in my spare time, and I tend to try to make reusable parts to save myself effort in the future. Because I have to order ingredients in certain quantities, I often wind up with more than I need for my project.
Before I got into reverse engineering, executables always seemed like black magic to me. I always wondered how stuff worked under the hood, and how binary code is represented inside .exe files, and how hard it is to modify this ‘compiled code’ without access to the original source code.
Let me set the right expectations first. This bug I found is actually not that complicated, it's very straightforward once you see what's going on. But I still think the process it took me to uncover this bug could be interesting. It's also kind of interesting that a simple bug stayed undiscovered for so long. I will…
Understanding the real world is not always easy. A Python simulation can help. And let's find ways of making it efficient, too.
