Let's talk about game simulations. Today I bring up a slightly more advanced topic and talk about OS scheduler latency and its impact on multi-threaded tick design.

The tools removed the resistance that used to tie us to what we build. Nobody is going to give it back, so the craft now has to be chosen, and part of that choice is not ours to make.

The most important change an engineer can make isn't a new language or framework — it's a single sentence about what they think they're doing. 'I am writing code' makes the diff the deliverable and…

A follow-up to my post on Gradle's rich console on Nix: a small patchelf script in my nix configuration that repairs the native library cache whenever the Gradle wrapper breaks rich console.

I remembered the conversation: transcribing a Rust cohort video with mlx-whisper. I didn't remember where I ran it. It turned out to be ~/Downloads, but I only found that out later: claude --resume…

I recently added a universal selector for CSS custom highlights, ::highlight(*), to the relevant CSS Specifications (the bulk of it is actually in CSS Pseudos not CSS Custom Highlights) and…

What happens without a search query?

Every so often someone needs to get into our house while we’re away, like a family member dropping something off or a repair person showing up early. I didn’t want to hand out a garage remote or set…

I'm finding that I sometimes don't have time to take notes when I need to, but I often times can record audio. Maybe it's just a random thought I need to capture, or a full conversation crafting a…

SCENARIO: The year is 1950, and a brand new Turing machine, the first of its kind, has been installed at a research facility. Lots of people want to use it, but the machine has just one tape. A…

incidental learning in the age of LLMs.

I noticed something odd while was running my streaming route: Task Manager showed the window using between 800 MB and 1 GB of memory. For an app whose job is to move audio from a microphone to…

Seven questions Git users have about Jujutsu (jj): GitHub compatibility, missing Git features, the learning curve, using it at work before v1.0, and the story behind its name.

Nothing derails a writing session quite like a $\LaTeX$ build that fails without telling you why. You hit save, latexmk spins up, and suddenly the compiler halts with a vague Error return from 'biber…

Noise with CSS backgrounds

Converting existing open-source FPGA projects to Bazel and rules_openxc7 makes hardware builds reproducible, eliminates machine-specific paths, and enables one-command bitstream generation without…

Use @c @implementation to preserve a C interface, check signatures at compile time, and keep buffer ownership and failure behavior explicit.

I went to an event at Sickhouse.

I like Apple laptops, but that self-satisfied “Made in California” vibe is just too much. When they started forcing people to watch aerial shots of the Sonoma Valley every time they log…

transcribe_cpp turns speech into text on the phone itself, live and hands-free, on iOS and Android. Why I built it and what turned out to be hard.

Four months after Phrase Algebra and Sharpee 2.0, the algebra has grown from 13 kinds to 16. Two of my June examples were never valid syntax, and the Optional and Choice examples contradicted…
