Why WinQuake exists and how it works

Notes about VK_EXT_custom_resolve

Vulkan 1.4.333, released on November 14th, includes VK_EXT_custom_resolve, an extension that is closely related to the work we have been doing at Igalia to help Valve release the Steam Frame. It’s an extension that allows you to use a custom fragment shader to specify how to resolve a multisample image into a single-sample image, typically so the latter can be presented on screen. CTS tests for that extension were written by yours truly in close collaboration with Turnip developers, and are now public.

When using classic render passes from Vulkan, the extension only adds a flag that you can use to mark...

JavaScript Input Buffering: a simple project to show delayed keyboard events

In this post I’ll show you a simple but powerful JavaScript experiment that visualizes keyboard input in real time and with a one-second delay. It’s a small project built with pure HTML, CSS, and JavaScript, designed to teach essential concepts like keydown/keyup listeners, precise input timing, and requestAnimationFrame loops; the same fundamentals used in games, replays, and input debugging tools.

How quake.exe got its TCP/IP stack

OpenAI employees… are you okay?

You might have seen an article making the rounds this week, about a young man who ended his life after ChatGPT encouraged him to do so. The chat logs are really upsetting.

Someone two degrees removed from me took their life a few weeks ago. A close friend related the story to me, about how this person had approached their neighbor one evening to catch up, make small talk, and casually discussed their suicidal ideation at some length. At the end of the conversation, they asked to borrow a rope, and their neighbor agreed without giving the request any critical thought....

Еще один самодельный компьютер. Coolsystem — Часть 1

Сегодня мы будем делать еще один восьмибитный компьютер. Да, я еще не наигрался со всеми этими штуками.

Coolsystem - идея компьютера, сочетающего в себе идеи о защищенной среде выполнения (причем в очень-очень специфичном варианте) и способного запускать готовый софт для восьмибитных персоналок 80-х годов. Также он может использоваться для изучения основ схемотехники, своего рода учебный компьютер.

What's up with FUTO?

Some time ago, I noticed some new organization called FUTO popping up here and there. I’m always interested in seeing new organizations that fund open source popping up, and seeing as they claim several notable projects on their roster, I explored their website with interest and gratitude. I was first confused, and then annoyed by what I found. Confused, because their website is littered with bizzare manifestos,1 and ultimately annoyed because they were playing fast and loose with the term “open source”, using it to describe commercial source-available software.

FUTO eventually clarified their stance on “open source”, first through satire and...

Cloudflare bankrolls fascists

US politics has been pretty fascist lately. The state is filling up concentration camps, engaging in mass state violence against people on the basis of racialized traits, deporting them to random countries without any respect for habeas corpus, exerting state pressure on the free press to censor speech critical of the current administration, and Trump is openly floating the idea of an unconstitutional third term.

Fascism is clearly on the rise, and they’re winning more and more power. None of this is far removed from us in the FOSS community – there are a number of fascists working in FOSS, same...
