Status update and new package manager announcement

I just had two really different feelings at the same time. I am working on a web app, and I’d say I’m doing quite a bit to make the whole app and team function. I’m committing tons…

A tiny, type-safe Google Analytics integration for TanStack Router and TanStack Start with automatic page views, typed GA4 helpers, and clean SSR-friendly setup.

String is the most-used type in any Java codebase, without much competition. And yet, most developers don’t know much about what actually happens under the hood.

GitHub notifications are noisy where they should be quiet and silent where they should be loud. I built GitNotifier to prioritize human signal, reduce Slack channel spam, and let developers act on…

Two years ago, I was pondering ways to enhance borrowck with proof-based analysis. At the time, I was only aware of formal verification tools for functional languages, while Rust is impure. For the…

How does Claude Code's new /btw command work, figuring it out from the minified source.

My Emacs misconceptions Emacs Carnival Mistakes and Misconceptions Philip Kaludercic has started the Emacs carnival on the subject Mistakes and Misconceptions. Here's my contribution. Vim to Emacs In…

Whatever your thoughts on AI, it’s pretty clear using LLMs to generate code is here to stay in the workplace. AI models have got so good at writing code, that at first glance, it seems trivial to…

6,900 Ways to Say ‘Goodbye’ to FontAwesome React Navigation has been slowly building up its Alpha—and I’m not talking about the team piling onto Satyajit Sahoo during some sort of alcohol-induced…

Claude Code lets you customize the status line at the bottom of your terminal. The default suggestion is a bash script, which works but gets clunky fast and difficult to maintain for more complex…

Walk through a casino and you will see rows of slot machines. Someone sits down, pulls the lever, watches the reels spin, and waits for the result. Most of the time nothing happens. Occasionally a…

Updated bouncing: Added bounce mode "Flip2D", which can be combined with other bounce modes. The Emergency Alert System will now trigger if you try to bounce a window that is too tall or wide. Bio:…

The buffer-guardian package provides buffer-guardian-mode, a global mode that automatically saves buffers without requiring manual intervention. By default, buffer-guardian-mode saves file-visiting…

Claude is changing how I write software dramatically.My biggest worry, as someone who's been writing software for a long time, is that I will be so blinded by my hard earned intuition on complexity…

One challenge I have, doing what I do, is getting into "discussions" with enterprise engineers who like to throw the weight of their enterprise position at me. This happens a lot.…

Only code visible by default. Tools appear one at a time, on demand, then disappear. No plugins are needed.

The project did not start as a Kanata fork. It started as Layerpad: a standalone experiment in using touchpad activity as a modifier signal. The source lives at github.com/tompassarelli/glide. The…

It's the first day of March December Adventure (really the second day, but I was busy yesterday), and my goal for this week is to learn more about how Jessica Tallon's Mandy prototype works so that…

Back in 2021 I did some analysis of PyPI package names and version strings in the post The rinds of the Cheese Shop menu. Five years on, let's see how things have changed. At the time of writing,…

PyCon US is coming to Long Beach, California in 2026. This year for the first time ever there is a day-long talk track devoted to the latest in Python security . This new talk track is titled “…

Textual is a great Python user interface package. Textual lets you create a GUI-like interface in your terminal. You can use many different widgets in Textual. However, the widget you will be…

A background task in Claude Code silently grew a single .output file to 324 GB in 16 minutes on my Mac. I went through the session logs to understand why. Turns out others have seen up to 740 GB from…

Tony Hoare at the LASER summer school, September 2007 (All photographs in this article are by the author) Had they included just one of Tony Hoare’s major achievements, many scientific careers would…

Mamba has been a key figure in the topic of efficiency; the SSD layer is a linear recurrence that scales better than attention at long contexts. The recurrence itself is sequential, each hidden state…

The first time I opened the BlackDuck API documentation, I thought building a vulnerability collector would take a couple weeks. Fetch some projects, grab their vulnerabilities, write them to a…

Picked up learning Python again. I learn it daily with codecademy.

Where the animation is annoying, the code is too damn long, but then the ability to do a slow upscrolling crawl of yellow text suddenly gets to me.

Radicle is an open source, peer-to-peer code forge built on Git.

There is a moment in software development — familiar to anyone who has shipped a UI — where the gap between "the code does what I think it does" and "the UI does what users experience" turns out to…

问题不在于还要不要更强，而在于强在哪儿 过去两年，AI 编程领域几乎一直在讲同一件事：模型越来越强，写代码越来越好，能连续完成的工作越来越多，审代码、修问题、在整个代码仓库里改代码也越来越稳。 这个判断并没有错。强模型确实在快速接手软件开发里很多重复、机械、消耗注意力的工作，比如样板代码、搭建测试框架、接口对接、常规修补和局部重构。这些事情以前需要工程师持续盯着做，现在越来越多都可以交给模型。…

I built a Chrome extension to make NYC apartment hunting on StreetEasy less painful by showing move-in dates, hiding noise, and adding notes/tags/ratings.

Software used to be hard. We paid Alpha Engineers like professional athletes because they were the only ones who could turn a vision into a functional machine. For a decade, the legacy software…

In previous posts, we have written about the generation of synthetic populations based on real world locations, and how such populations can have various types of networks associated with them. We…

In the previous posts in this series, we established that when you give an LLM a list of function tools, the model must interpret JSON schemas at inference time and produce structured output that…

Communication is one of the most critical skills for engineers to master, yet it's often overlooked.

Locations are easy, right? All you need are coordinates - longitude and latitude - and you can put things on a map. But once you need distances, intersections, containment checks, or anything more…

Recently I switched from Void Linux to Freebsd, I mentioned in my last blog post that I now use vanilla vim as my primary text editor instead of GNU Emacs or neovim. I decided to install vim by…

“Why are you being so difficult? This could be a good thing for us? How can you be so sure?” This was in late 2000. We were having drinks in the Watershed in Bristol. For those of you not familiar…

Our community-powered reference site for OpenAPI devtools hits its stride. Also in this dispatch: a podcast with Supergood, oapi-codegen for Golang, Vacuum OpenAPI Linter updates, and more!

Founder Alex Klarfeld joins us for a podcast interview, with an update on Supergood's product journey, reverse engineering APIs ethically, and automating tech for old industries
