T3 Code provides a convenient interface for working with coding agents such as Claude Code and Codex. One of its more interesting features is that the T3 client doesn’t need to run on the same…

The previous post ended on a pattern: a memory hierarchy works because one component can see the whole path, and disaggregation splits that visibility across two vendors. Scheduling has the same…

There is so much fluff out there telling us that we are nearing the limits of our current technology. I would argue that couldn’t be further from the truth. As...

Linus Torvalds released Linux 7.2 as expected on August 16th, which means a lot of my changes and reviews will hit a lot of machines around the world (and hopefully won’t cause any serious bugs!).

Imagine joining a software project a few years from now. It is a large, mature system. It has thousands of business rules, years of operational experience, regulatory obligations, performance…

A timestamp records when a wiki page was written. Nothing in the format runs to keep it true. Twenty-one years after I helped build a commercial wiki, the LLM-wiki idea is back, and it dropped the…

I moved 177 entries out of an index and the consistency check went green without looking at any of them. Over nineteen days I collected twenty-four of these across modules that never met, and they…

I built a tiny piano app and found a chord that physically cannot be played on a MacBook keyboard. The bug wasn't in my code—it's soldered into the keyboard, and it's been there for sixty years.

I spend most of my time in the AI DevKit agent console. I start one agent as the manager, usually Codex, and brainstorm with it. Once an idea becomes concrete enough to execute, I ask the manager to…

No chart library needed. Inline SVG plots your data in 15 lines, scales to any container, and styles with the same CSS as everything else.

The last post argued that a KV cache has no interchange format. Grant one anyway. Suppose the two vendors agree on layout, dtype, block size, scale placement and every other axis in that list. The…

by Adam Argyle This project aims to make it easy for CSS to have access to things only JS could have previously, all through CSS variables. This makes it way easier for CSS to still be responsible…

I just want to show you some pseudonymization ideas, and the point where they stop working.

For years Sass offered us superpowers. It was a superset of CSS, opening up a world of possibilities for developers. The ability to use variables, functions and nest our rules was too good to turn…

[Java][JVM][Tuning][Profiling][G1][JIT] Why is Arrays.fill 265 times slower on G1GC?

A bot opened a pull request that reads completely fine. The machine that checks these for me refused it twice, in three seconds each, for a reason no amount of reading could have found. For ten…

I spent two days on a bug where a screen-capture stream never came back after the display went to sleep. When I finally had a patch I believed in, I ran it, put the machine&rsquo;s display to sleep,…

Video Link: Jayaprabhakar Kadarkarai - Create your own DSLs This is technically a link to a talk contained within a video. The entire video is worth watching it&rsquo;s the lightning talks at the…

An example of the heap package, re-imagined as a generic heap.

I ported Syndicate (1995) to the web.

So I have been having a bunch of random thoughts as I have been working through reacquainting myself with my C++ game, Pillage and Plunder. So I figured I would write them down to get them out of my…

Sometimes you just want a simple way to look at your traces, metrics, and logs without setting up a full observability stack. Just a UI where you can see what your applications are doing, without…

The hardest thing about running an arm’s length software factory has been anything that touches UX. If your quality bar is high, a human still has to look at a screen and use it, and what comes back…

Separate terminal rendering, durable sessions, and remote access so a context switch, disconnect, or laptop change does not turn active engineering work into a scavenger hunt.

I wanted to find the number of citations per year for a paper from my dad, at least per Google Scholar. Hacking around, here&#8217;s a little JavaScript to get it per results page: How would you do…

Is it possible to write a PySide6 application without using .ui files or Qt Designer? How can I create widgets and lay out a window entirely in Python code?

Throughout my professional career as a programmer, I read lots of books. They helped me deep-dive into topics I wanted to gain more expertise in, uncover new topics, or sometimes they simply inspired…

This was a very old draft I&#8217;ve had sitting around for years. The recent discussions of new query languages like Acadia spurred me to revisit, revise, and publish this. I think one of the…

well i didn't manage to get anything done for html day this year, so thank you to Ross A. Baker for bringing the HTML tasting menu! his bite-sized benchmarks can be used to test your css, so fork…

Recently a bug was reported to op-sqlite, it was a crash that only reproduced on hot reload or a CodePush/OTA update. Never on cold launch. The stack trace pointed at ~jsi::Value() inside…

This is part of a pair of articles on the impacts of agent driven development - you can read thoughts on the review process here. I threw away the entire AI for Annhexation and started again.…

TL;DR Git is going to have (or by now has &ndash; via 2.54.0) a new, well, sorta, new feature called git-hooks which you can define in your configuration. This article will explain the how. The way…

To start: The Phoenix Code Annoyance. I found out how to use it without having to deal with the AI bullshit. For some reason, it breaks and resets the phcode.json if you update it so that it doesn't…

I was happily coding my RSS Feed reader, grabbing screenshots, taking notes when I suddenly found a wild bug: Did you see that text area collapse? Yeah, me too. And I didn’t like it. The thing is, I…

My thoughts on a concept that keeps coming up.

A post about how I do AI-assisted development in the cloud, with a link to a Github repo for setting it up yourself.

Last time I built a detector that counts four-letter runs (n-grams) and tells you whether Claude Opus 5 wrote something. It works well - about 91% on text it has never read. It has one obvious hole:…

How I use Obsidian as the markdown editor and project organizer next to Claude Code. No plugin, no MCP server, one folder per project.

The Bear notes app recently added a CLI for interacting with your notes. Let's use it to build a script for creating backups of my notes! Prerequisites Here is the stack I am using: Bear (duh) Fish…

I have a lot of open source projects. Many are Swift packages, but I also have a few apps as well as a bunch of other projects in Ruby, C, and probably others too. I have realized over the last year…

A plan of mine hinged on "a startup hook can only add context". The installed Claude Code binary said otherwise, and the docs would not say so for weeks. Docs lag, omit, and describe the version the…

v0.1.1 release article for the Jellyfin Media Integrity Scanner. Covers update checker architecture, session-aware auto-restart, package bloat fixes, Playwright E2E testing, media corruption test…

We named a proof obligation about how fast a shallow exp–log expression can approach zero. It fit the lower-depth results and it looked right. It was false — and false at exactly one scale. Replacing…

Apollonius' problem has eight solutions in generic position. While formalizing it in MachLib we assumed the obvious general-position condition — three equal circles, comfortably separated. That…

How I run a coding LLM locally on a single RTX 3090 Ti — the model journey from Claude-distilled to a dense 27B coder, why MoE beat dense for speed, why I stayed on llama.cpp over vLLM on Ampere, and…

Introduction In a previous article, we showed how to perform the Chi-square test of independence in R in order to test whether two qualitative variables are related. As mentioned in that article (and…

It's been a month since we launched, so I'd like to make a brief post highlighting some of the results that have landed in Tau Ceti. We're ready for more contributors at this point. Please come to…

Today we're launching the Palomar Registry, an index of formalized mathematics repositories with a valid #comparator setup and #formalization.yaml metadata. Limited automatic review rejects…

This is a write-up of a weekend project, vitald, I made after buying a Google Fitbit Air (I’m slowly transitioning out of the Apple ecosystem). One of the main reasons I gravitated towards the Fitbit…
