With several posts on this website attracting significant views in the last few months I had come across plenty of feedback on the tab gimmick implemented last quarter. While the replies that I came across on platforms like the Fediverse and Bluesky were lighthearted and oftentimes with humor, the visitors coming from traditional link aggregators sadly weren’t as amused about it. Obviously a large majority of people disagreeing with the core message behind this prank appear to be web developers, who’s very existence quite literally depends on JavaScript, and who didn’t hold back to express their anger in the comment sections as well as through direct emails. Unfortunately, most...

Now

Traveling through Asia Working on Zeit Working on a modern bulletin board Moving towards decaf coffee with Lion’s Mane Finished migrating all my active projects away from GitHub towards Codeberg Began migrating the Go modules path of my projects from github.com/mrusme/* to xn--gckvb8fzb.com/* Had some fun the other day building an XMPP chat bot for the VT100 community that connects to any OpenAPI API and responds to mentions as well as private messages: https://codeberg.org/mrus/hal9001 (Caution: crude code!)

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.

ELMterm, CornucopiaStreams, and the joy of clean automotive telemetry

Back in 2016 I fell deep into the rabbit hole of automotive diagnostics. What started as “let me decode one CAN frame” quickly became a multi‑year tour of every adapter I could get my hands on: ELM327 clones, genuine STN units, Bluetooth dongles, USB‑serial cables, Wi‑Fi gateways, even a few early BLE UART experiments. Each promised to be the answer, yet every session ended with the same friction—flaky transports, unreadable hex dumps, and notebooks full of copy‑pasted traces. Eventually I built my own hardware so I could trust the bits on the wire, but I still lacked a terminal that...

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. The neighbor found them the next morning.

RetroPlayer – Bringing the Sound of My Youth to iOS

Some projects aren't just about building software—they're about preserving memories, honoring the past, and sharing what shaped you. RetroPlayer is one of those projects for me. Growing up in the 1980s, I spent countless hours in front of a Commodore 64, and later an Amiga, absolutely mesmerized by what these machines could do. The graphics were captivating, the games were endlessly replayable, but what truly captured my imagination was the sound. The SID chip in the C64—with its distinctive three voices—could produce music that seemed impossible for such simple hardware. Composers like Martin Galway, Rob Hubbard, and Ben Daglish weren't...
