A deep dive into Emacs's widget library: what it does well, where it falls apart, and a step-by-step case study of building a table widget with editable cells. Includes working code and hard-won lessons about state management, layout hacks, and cursor position preservation.
The barrier to entry for building software has collapsed. The barrier to building something that matters hasn’t moved an inch.
Comparing token efficiency across 19 popular programming languages using RosettaCode data - from Clojure to C, there's a 2.6x difference.
Not that long ago I became aware of Justine Tunney's cosmopolitan libc project. It's a toolkit that allows you to compile C source code into a single binary...
Exploring five critical questions shaping software engineering through 2026, with contrasting scenarios for each. These lenses help prepare for the evolving ...
The accepted practice is to not add lazy-loading to images above the fold, especially the LCP image, since doing so can delay their loading until the browser has determined they are definitely in the viewport. One problem though is that "above the fold" depends on screen size: an image can be above the fold on desktop…
Someone on Reddit recently asked: What would make a Rust implementation of something faster than a C implementation, all things being the same? I think this is…
A few months ago, users started reporting that Ghostty was consuming absurd amounts of memory, with one user reporting 37 GB after 10 days of uptime. Today, I'm happy to say the fix has been found and merged . This post is an overview of what caused the leak, a look at some of Ghostty's internals, and some brief…
As my cat woke me up way too early for a Saturday morning, I decided to put all this extra time (and my ChatGPT Pro subscription) into good use and generated a QR-code generator for PostgreSQL, written as a single pure SQL statement. No external libraries or Postgres extension installation needed! The pqr.sql example…
Why you might not need Oh My Zsh for your Zsh configuration.
Debunking an alarmingly common HTML misconception.
Sometimes, you need to deal with secrets in an interactive shell. Say, for example, you want to do things with the API of a GitLab instance for which you require authentication:
Made in Notion, the connected workspace where AI agents and teams organize docs, projects and knowledge together.
Why std::move is just a cast, how it kills RVO if used wrong, and the mechanics of ownership transfer.
The core of tools like Claude Code, Cursor, and Warp isn't magic. It's about 200 lines of straightforward Python. Let's build one from scratch.
~15 years ago, we had Balsamiq Mockups (2008). Deliberately sketchy. Intentionally low-fidelity. The comic-sans-looking wireframes were a…
In Go, go.mod acts as both manifest and lockfile. There is never a reason to look at go.sum.
As a maintainer of several OneBusAway projects, I regularly ask contributors to rebase their branches before merging. The response is often hesitation or…
Standards are great, until they aren't
What the **** does that mean?
Three months ago I would have dismissed claims that AI could replace developers. Today, after using Claude Opus 4.5, I believe AI coding agents can absolutely replace developers.
The current state of app bloat.
How we built memchunk - a blazing fast text chunking library using SIMD and memchr for RAG pipelines
reverse engineering, abandonware
For many years VSCode has been my day-to-day IDE for everything: Python, Go, C, occasional frontend development, and what not. It was never...
Running six Claude Code agents in parallel from an iPhone. A cloud VM, Tailscale, mosh, and push notifications enable async development from anywhere.
We develop fast Rust crates and release them fast.
Lessons learned from 14 years of engineering at Google, focusing on what truly matters beyond just writing great code.
AI tools brought me back to levels of productivity I haven't felt in years. Web development is fun again.
