First: performance is tricky and bechmarking even more so. I will talk some numbers in this post but of course they are what I have measured for my specific tests on my machine. Your numbers for your test cases will be different. Over the last six months or so, curl has undergone a number of … Continue reading curl 8…
This tutorial is loosely based on a 46-page paper by Paul-Virak Khuong and Pat Morin “Array layouts for comparison-based searching” and describes one particular way of performing efficient binary search by rearranging elements of a sorted array in a cache-friendly way.
I read a blog post by Alex Muscar, “Beautiful Binary Search in D”. It describes a binary search called “Shar’s algorithm”. I’d never heard of it and it’s i…
Hidet is a powerful deep learning compiler that simplifies the process of implementing high-performing deep learning operators on modern accelerators (e.g., NVIDIA GPUs). With the new feature of torch.compile(...) in PyTorch 2.0, integrating...

Developers often believe that software performance follows a Pareto distribution: 80% of the running time is spent in 20% of the code. Using this model, you can write most of your code without any care for performance and focus on the narrow pieces of code that are performance sensitive. Engineers like Casey Muratori…
A guide to learning COBOL for the modern programmer.
This page is a "brief" summary of some of the huge number of improvements in GCC 13. You may also want to check out our Porting to GCC 13 page and the full GCC documentation .
An overview of Rust GUI libraries and frameworks, focused on WASM. Discover the latest GUI toolkit options for Rust, increase your programming skills, and create efficient WebAssembly bundles that will help you build comprehensive applications.
There are many legitimate arguments to be had about performance, but there are also plain old excuses. It's time to end the excuses.

Ruby's switch statement is very versatile and flexible, especially due to the dynamic nature of Ruby. This post shows how it works with examples.
I wrote a blog post a while ago complaining about Gradle, mostly from a position of ignorance: I had never really taken the time to properly learn the tool and I was frustrated while trying to stumble my way through working with it. But luckily, my company encourages learning and experimentation so I was given an…
The futex ( f ast u serspace mu tex ) is a Linux kernel feature designed for synchronization primitives (mutexes, condition variables, semaphores, etc.). Like many topics in concurrency, they have a reputation for being tricky (for example, see the paper Futexes Are Tricky ). Despite that, they really are a…
Debugging is difficult. Debugging across multiple languages is especially challenging, and debugging across devices often requires a team with varying skill sets and expertise to reveal the underlying…
A self-contained introduction to Gröbner bases and solving polynomial systems
Since 2013 I’ve had the chance to use OCaml a few times in different jobs, and I got frustrated and disappointed every time I had to use it. I just don’t enjoy writing OCaml.
I procrastinated a deep dive into transformers for a few years. Finally the discomfort of not knowing what makes them tick grew too great for me. Here is that dive.
The first official GCC 13 release is just around the corner, and you may be a bit surprised to find out that gccrs will not be included in it. The aim of this blogpost is to go into a little bit more detail as to why this was done and how you can still try out our compiler if you’d like to.
F38 just released and seeing a bunch of people complain that TF2 dies on AMD or other platforms when lavapipe is installed. Who's at fault? ...
A few months after my contract with Haiku, Inc. began, I rewrote the implementation of the Haiku kernel’s condition variables (as opposed to our userspace condition variables, which are from POSIX.) As this new implementation has run in Haiku …
We’d like to announce the availability of the QEMU 8.0.0 release. This release contains 2800+ commits from 238 authors.
Let me tell you a story about how Windows users are deleting files from their installation and as a consequence end up in tears. Background The real and actual curl tool has been shipped as part of Windows 10 and Windows 11 for many years already. It is called curl.exe and is located in the … Continue reading deleting…

The Z Garbage Collector (ZGC)—a scalable, low-latency garbage collector providing sub-millisecond max pause times—continues to evolve. This session will review the design goals behind ZGC and provide a look into the impact of the upcoming support for multiple generations. It will also present general guidance on…
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
It was way back in the summer of 2019 when I first became a member ( i.e. a Fedizen!) of the Fediverse, the distributed social network formed by various Free and Libre servers communicating using the Activitypub protocol.
Earlier this week a letter from an activist imprisoned in France was posted to the internet. Contained within Ivan Alococo’s dispatch from the Villepinte prison
