Discover how SwiftUI provides built-in formatting support that makes it easy to display and edit numbers, currencies, dates, measurements, and more directly in Text and TextField views.

Six years have passed since I started building EndBASIC: a retro-looking BASIC interpreter that works on the web, on the desktop, and on embedded hardware—and that allows writing cross-platform…

I built something that makes my life a little easier, maybe: a tiny mental math quiz: Daily Math. I want to maintain a little bit of mental math skills with minimal effort, and I heard one of the…

I attended Anthropic's Code with Claude developer conference in San Francisco on May 6th. Here's what I learned about context management, the shifting bottlenecks in software engineering, and what it…

In the DevOps engineer’s toolkit, few commands are as revered—or as misunderstood—as awk and sed.

A data pipeline is a set of choices. It's almost always a bet that you know how this data will be used, how it needs to be modeled, how it needs to be queried. I've watched a data engineers…

--> What are we doing here? Where are we going? Are we going anywhere? Does it matter? I started this dungeon map endeavor because my brother Hill was doing something with gerrymandering maps, and…

Nothing to do with pets, unfortunately.

Finally: successfully leverage all the chatbot friends, and an entire year's worth of tinkering experience to get MEH commenting up and running on my site. Leave me a note!

Get better at: handling multiple files, multi-indexes, pivot tables, and plotting with Plotly.

In the last ~6 months, Agent Skills have gone from a new feature introduced by Claude Code to a widely adopted paradigm across the industry. Companies that want to signal they understand customer AI…

Even though I've been job searching for four months now, I am busier than I have ever been. You know what I mean. You've seen this blog! One week I am experimenting with AI, the next I am pairing…

What happened was, after 10+ years of not exercising, I started running again for real in 2025. I've been tracking progress in my head, in text files, a spreadsheet. Madness. The next logical step is…

I have released SatPulse 0.2. This is a major new release with a lot of new functionality (more than 60% of the code is new since 0.1).

In the recent weeks I've been engaging Prot as an Emacs coach to help with doing review passes over my upcoming ffs package as I work on polishing and documenting it in preparation for offering it…

It's been a weird year. Last May I was working full-time for a client when they announced that they wanted to try Claude Code. Suddenly, I was furnished with an account and encouragement to try it…

A couple of months ago I referred to a quote from Infocom's internal ZIL manual: The other four tokens—ON-GROUND, IN-ROOM, HELD, and CARRIED—are incredibly confusing, and no one really understands…

After attending recent conferences and learning that I can swap out buckets of JavaScript for the HTML native popover property, I've been using it liberally throughout my own projects. For little pop…

I met with Amin Bandali to talk about Emacs, specifically Amin's upcoming ffs.el package.

We just released another minor update to our shadcn/ui kit: 1.9.4. As always, you can see detailed changes in our changelog. In 1.9.3 and 1.9.4 we continued to move customizations on the component…

A CLI and MCP server that aggregates trust signals about open-source code, projects, and the people behind them — so humans and LLM coding agents can decide, on evidence, whether to adopt a…

Today I had a fun one, where I finally dove into something that was bothering me for days: since a couple of days I had been getting questions from my different GitHub Copilot sessions to close some…

I decided to participate in Jack Harrhy's "game jam-like" for text-based projects, textjam . It's my first time participating in any kind of a jam. The requirements are pretty permissive. We just…

In this episode, Conor and Bryce chat with Marco Franzeb Salgado about a potential GPU implementation of the rotate algorithm (Part 2).

As we all go about our day we discover bits of wisdom that WOW! and YES! seem to be directed at you. I like to put these bits together in a file for later review. Using the programs fortune and…

I use a Makefile to move my emacs configuration from its git repo in my home directory to the emacs config directory. There are a variety of better ways a person could move files from one place to…

To my surprise, I have a new app to announce. That’s it. That’s all it is. Stask is a task tracking app that uses a stack to manage all manner of work items, from massive projects to tiny…

Hey, dipshit. You know what compiles in two seconds, deploys as a single binary, and doesn't shit itself when a transitive dependency gets yanked from npm at 3am? Go. The same way HTML has been…

Nick sent me a great post from one of the engineers at Goodenough, the fine folks behind Jelly, on the topic of self-updating screenshots. It is near and dear to my heart: their approach, which uses…

Building analytics on well-known public datasets earns stakeholder credibility before you write a single custom pipeline. Once the framework proves itself on familiar ground, automation and analytics…

Bigger prompts do not fix bad agent plans. A good agent workflow starts with a small brief, human review, task sizing, and checks against concrete artifacts.

A CLI is not only a user interface. It is also an API for scripts. Quiet mode, stdout, stderr, colors, and exit codes need clear contracts.

Two tips on using zig fmt effectively. Read this if you are writing Zig, or if you are implementing a code formatter.

Three months on from the last status update , three posts shipped, and the Eignex rewrite, splitting one experimentation library into focused pieces, has actually moved. This is a quick checkpoint:…

Something has changed for me at the bench in the last few weeks, and I want to write it down before it stops feeling new. I have spent the last decade building or using diagnostic tools that put a…

How my blog is setup (•̀ᴗ•́)و

Together with Javier Fernández Píriz, a PhD student at the University of Luxembourg, we are working on HomogeneousTools, a collection of packages meant to efficiently deal with homogeneous varieties…

The simplest improvement you can make to your agentic programming workflow is to run two agents instead of one. One writes code in its own worktree; the other, in a parallel worktree, reviews it.…

solve TwoSum or bufo, made with Chris

I really, really want local models to work. I want them to work in the very practical sense that I can open my coding agent, pick a local model, and get something that feels competitive enough that I…

Codex CLI Deletes Function-Style apply_patch

Codex CLI now ships a built-in codex update command that detects the installation method and applies updates automatically. No more remembering whether you installed via npm, Homebrew, or standalone…

What changes when a contract-first agent workflow becomes an installable Codex App plugin, not just a Claude Code command.

Recently I had an idea while exploring a new project that had some Tailwind components - why be forced to use UI I don’t want to use? In this age of LLMs, is it possible to take a component created…

Hotwire Native vs NativePHP: How Web Frameworks are Conquering Mobile and Desktop

Software engineering has always been more craft than science. AI doesn't change that.

(One of my summaries of the 2026 one-day PyGrunn conference in Groningen, NL). His parents owned a record store in some Dutch town. First records, then CDs. A social shop where you would gather to…
