We discuss different ways to combine the benefits of deterministic low-code development with the flexibility of AI and vibe coding

I’ve been building a fair number of Rails applications using Claude Code recently. Here are a few things I have built in the last few weeks using agentic coding:

Claude Code has skills, MCP servers, hooks, plugins, agents, channels, and custom commands. When do you use which? A guide to the extension ecosystem written by the tool itself — including features…

Learn how to initialize a canvas with hardware abstraction layers based on WebGL/WebGPU, design Canvas API, implement a plugin-based architecture, and create a rendering plugin. Build an extensible…

Learn how to add shapes to canvas and draw a circle using SDF (Signed Distance Field). Covers anti-aliasing techniques and dirty flag design pattern for performance optimization.

A couple of years ago, I wrote about Chris Maiorana’a post suggesting that writers adopt a one-line-per-sentence workflow. You can read his post on the matter to see his arguments on why. At…

Brian: I’m Brian Hall. And today we’re talking again about habits. In the last episode, we both set out some intentions to change our writing habits and establish a daily practice.…

Recently I was surprised to discover that there are several bad ways to do magic links. The basic idea is: a user hits “login”, enters their email address, and receives an email that…

Your website users can install applications to their PC on Mac, Windows & Linux. Your app can be accessed from the Start menu, desktop, or dock. Its super simple to convert your website into…

Since Ladybird team abandoned their Swift adoption for the browser I heard a lot of criticism about the Swift ecosystem and the interaction between Swift and C/C++ projects. My usage of Swift is…

This is Part 1 of a 3-part series on building skills for Claude. If you’ve ever wished Claude could just remember how you like things done, this series is for you.

I started the week playing around with some strange attractors. Kate Ertmann wrote a great post about the beauty of strange attractors, and they're something I've always been fascinated by, having…

The above GIF demonstrates some of the functionality of the Instrument Library and Piece Window at this point: selection of score language, filtering on names, drag-copying, deleting, etc. What you…

The job of a code reviewer isn’t to review code. It’s to figure out how to obsolete their code review comment, that whole class of comment, in all future cases, until you don’t need…

Existing GitHub-Slack integrations are either too dumb, too expensive, or both. So I built Honk — partly to fix real problems, partly because building things is fun.

wgsl-rs first milestone almost complete I've been working hard on the first milestone of wgsl-rs , which is essentially to get it feature complete. All WGSL vocabulary is now supported (WGSL "std"…

Stripe is one of the most popular payment gateway and very easy to integrate in PHP, In this tutorial I will show you how to integrate stripe payment gateway using PHP in some easy steps. I will…

Started Reading.

With AI doing some or most of the code writing (ahm! generation, if I may), being strong in the basics becomes even more crucial. If you have the word "engineer" in your job title, then knowing tools…

The advent of web fonts popularised the use of icon fonts , i.e. fonts that consist solely of symbols and images rather than letters. Icon fonts such as Pictos, Font Awesome and Lucide have become…

When I published the original series in November 2025, I was happy with where the system landed. It had semantic caching, fallback strategies, distributed tracing, autoscaling, solid production…

I'm currently in a train from Berlin to Strasbourg and then onward to Marseille, traveling from the 28th(!) German Perl Workshop to the Koha Hackfest. I spend a few days after the Perl Workshop in ...

The software industry has a dirty secret: it rewrites everything every twelve years, learns nothing from the rewrite, and does it again. I've watched this cycle from three angles — as a developer,...

A couple of articles ago, I touched on Bazel transitions. In that context, I was referring to 1:1 transitions—transitions that change the single configuration of a target. Split transitions, on the…

Comprehensive guide to Claude Code's agent loop architecture, tool system, session management, and best practices for developers

I get asked this a lot. The short answer: use a terminal agent over an IDE-based one.

Tutorials teach syntax and controlled demos, not engineering. This piece defines engineering as building systems that work under real constraints—scale, failure, messy users—and introduces a…

A couple of days ago I released FatturaElettronica 4.0.6. It adds support for legacy windows-1252 encoding to both XML and P7M invoices, a long-standing annoyance that could previously be…

I needed to store massive OpenTelemetry data for AI spend analysis. Instead of reaching for BigQuery or Snowflake, I pushed 67,000 telemetry events per second into Postgres on a MacBook Air, while…

Django custom managers are a common way to exclude rows by default, such as inactive or soft-deleted rows. However, they don’t run everywhere you’d expect, which leads to unintended data…

Contentful's free tier ran out. I migrated 200 articles to self-hosted PostgreSQL in two hours with Claude Code. Here's the full playbook.

We ask at which floors we should place a set of idle elevators in a building so as to minimize the expected wait time of the next caller. If there is just one elevator, we show that it should be…

DevLog 6: Extending Markdown Markdown is ubiquitous nowadays. LLMs speak Markdown. Text editors embrace Markdown. I've been working with it both on my text editor side-project and on my main job.…

Linear has this hierarchy of layers to track, say, a feature. Not too dissimilar from all this "epic, story, task, sub-task" kind of nonsense that goes around. Linear calls it "project…

In my last post, I showed you how traits behave like passing a bundle of methods between functions, except automatically inferred by the compiler.

Building a business as independent developer around an open source data visualization tool

TL;DR: Jira to AI Agents Jira was named after Godzilla and built to track bugs. It became the default agile tool because it satisfied a deeply human desire: controlling work by putting it in boxes…

The Embedding Model That Actually Speaks Your LanguageTL;DR — A new family of embedding models covers 200+ languages (including underserved ones) in 8 different sizes, beats current leaders on…

I built an open-source AWS cost optimization tool in Go, but as it grew, the standard flag package became a bottleneck. Here is my experience rewriting the CLI architecture with Cobra, the breaking…

I have cobbled together a project in a few hours. It all started yesterday when I thought. "What if I had a notes app... that was structured like twitter?" . As I wrote in my blog post about that…

Good read. Learned that I don't need chalk if I want fancy colors in my console output.
