The “Exo 2” language allows programmers to write “schedules” that explicitly control how the compiler generates code. This allows performance engineers to transform simple programs into complex programs that do the same thing as the specification, but faster.
meshoptimizer implements several geometry compression algorithms that are designed to take advantage of redundancies common in mesh data and decompress quickly - targeting many gigabytes per second in decoding throughput. One of them, index decoder, has seen a significant and unexpected variance in performance across…
Today’s Speedometer release is more open and challenging than before and is the best tool for driving browser performance improvements.
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…
Hi, people of the future! Did you know that I wrote a follow-up article to this one, called “Further Thoughts on Wayland”? This original article was written in a more combative tone tha…
Our strategy for making updates and maintaining stability while we migrate languages.
asm.js is a simple subset of JavaScript that is very easy to optimize, suitable for use as a compiler target from languages like C and C++. Earlier this year Firefox ...
I edit videos non-stop nowadays. In a former life, I had a 2 TB backup volume and that stored my entire digital life—all my photos, family video clips, and every bit of code and text I'd ever written. Video is a different beast, entirely. Every minute of 4K ProRes LT footage (which is a very lightweight format…
API Documentation (Chinese) HuggingFace Demo ModelScope Demo Introduction After the release of Qwen2.5, we heard the community’s demand for processing longer contexts. In recent months, we have made many optimizations for the model capabilities and inference performance of extremely long context. Today, we are proud…
If you're a programmer who's become fed up with software bloat, then may you find herein the perfect antidote.
QuickTime ruled from 1991-2019, and was bigger than Apple itself. But can you name what replaced it, and whether it works as well?
To kick off 2026, I had clear objectives in mind: decommissioning my trusty VPS and setting up its successor. Embracing a complete paradigm shift, I built myself a container-centric, declarative, and low-maintenance setup for the years to come.
There is this growing sentiment in tech that stacking more and more layers of complexity to reach the sacrosanct "infinite scalability" is not the way forward. First, because it rarely materializes: you need a lot of other things than fancy tech to reach millions of people. Second, because the tradeoffs
In this text I will explain what makes OpenBSD secure by default when you install it. Do not take this for a security analysis, but more like a guide to help you understand what is done by OpenBSD to have a secure environment. The purpose of this text is not to compare OpenBSD to other OSes but to say what you can…
A blog titled Shipping Seven has gotten a lot of traffic recently for their article about Windows 7 and the MinWin kernel – namely, how they’re actually one and the same. The argument o…
As discussed in the January blog roadmap , I want to concretely describe a reduced Oil language , and see if we can get it "done" in 2020.
For every deploy, scale down event, or pod termination, users of GitLab's Pages service were experiencing 502 errors. This explains how we found the root cause and rolled out a fix for it.
Lightweight virtualization is a natural fit for low power devices and, so, seeing that the extremely popular Raspberry Pi line got an upgrade, we were very keen on trying the newly released Raspberry Pi 4 model B. Getting the board up and running with a 64bit kernel (and a 64bit userland) proved to be kind of a…
Real-time Ubuntu brings end-to-end security and reliability to the time-bound workloads of modern enterprises. With support for real-time compute, Canonical furthers its commitment to providing a best-in-class experience for open-source software consumption. 14 February 2023, London: Canonical today announced the…
I’d like to talk more about a container technology that I really like that I touched upon in a previous article : systemd-nspawn .
So, what’s Amazon Elastic Container Service (ECS)? ECS is a managed service for running containers on AWS, designed to make it easy to run applications in the cloud without worrying about configuring the environment for your code to run in. Using ECS, you can easily deploy containers to host a simple website or run…
I used to run FreeBSD on older laptops – some more then a decade old – like my favorite ThinkPad W520 daily driver or ThinkPad X220 mobile companion. Today I will share with you my expe…
Today, I would like to discuss a project that I care very deeply about: the musl libc. One of the most controversial and long-standing debates in the musl community is that musl does not define a p…
