Last year I founded the Gem Fellowship with $100,000 in funding. Myself and the gem.coop team judged applications from 40+ projects and funded eight with awards between $2500 and $20,000. This year…

For more than 20 years, I’ve been part of the KDE community, one of the largest and most impactful Free and Open Source software community world-wide. Yesterday, KDE turned 30 and this went…

Make something work before scaling. Figure out why it’s got friction. Be sure you understand the right solution. Do it again, make it painful. Then automate.

AI coding makes it easier and quicker to re-create existing applications with new code, side-stepping copyright concerns since copyright protects code rather than specification. In February this year…

How 805 coding-agent runs on throwaway boxes took formbook from zero to 489 court-filing templates, mostly in two days, and what the data can't tell you.

On October 8, Firecrawl launched Universal Scrape . The scrape endpoint I have been feeding URLs to for this whole series now answers questions about podcasts, people profiles, company financials and…

Most likely due to CRLF differences. On WSL side, run for current repo: 1git config core.autocrlf input

The 15th of October was my Twenty Sixth Year Anniversary with Ruby! 1242 gem releases, 15284 commits. More to come!

Iterator helpers run the same map and filter chain lazily, one value at a time, and stop as soon as you have enough. Here’s when that beats array chains, and when plain arrays still win. Continue…

A procedurally grown linden. The branching structure comes from the simulation described below.

Custom elements are amazing . They’re a built-in browser feature, not some library you npm install and then hope it will be maintained. You define a tag once and it just works, anywhere and in any…

Virgil is a tool that interactively guides you through building a 9P server. It does this by starting with the simplest of tests and builds from there. When a test fails, it stops and describes what…

I built a Laravel app in Claude Code cloud sessions with a $250 credit. What worked, what broke, and why I still prefer my laptop.

Why Estudely PDF processes documents in the browser, how three libraries divide the work, and what that choice means for privacy and performance.

Turning a public transit feed into a bus map, and sharing the work of refreshing it across everyone watching.

The first professional program that I wrote was way back in 1998 along with Gaurang where we both created an accounting, inventory and point of sales system for the Air Force Wives Welfare…

Nobody who told me about it anyway.

The numbers first

Harness engineering is changing how software gets built, but our practices haven't kept up. After a year engineering without reading code and operating autonomous software factories, I've found the…

I've been working for a while now on the Veilamp mobile apps (android and iOS), and field testing for a couple of weeks now. It's always worked, in that I could stream music with it... but the…

Cheapskate is a tool I’ve made over the last few months to help manage investments. You visit once a month with statements from all your bank accounts, and Cheapskate parses the individual…

Previous posts in this series introduced Frml , explained how it checks simplar scalar code and handles contracts between functions , and then discussed how it deals with loops , checks arrays , and…

57 agent sessions each started their own copy of every stdio MCP server. I shared three over localhost HTTP and dropped the fourth, which took them from 19.5 GB to 301 MB after two auth fixes.

Une petite page d'accueil en Go qui se construit toute seule à partir des services Tailscale de mon tailnet, avec des icônes et des health checks en direct.

A small Go start page that builds itself from the Tailscale services on my tailnet, with icons and live health checks.

I brought Mario Kart 64 to my phone with WebAssembly, lighter textures and Tour-inspired controls, then gave the coding agent a way to test its changes before I played them myself.

AI agents are very effective at finding vulnerabilities in our software. This includes the kernel (the proof checker) of the Lean proof assistant. See our two recent postmortems (August 1, August…

If your organization is blocking the default NPM registries, when you try to enable voice mode in Github Copilot, you’ll get an error similar to the following:

AI coding agents write code faster than teams can review it. Here are the automated checks to run at each stage, from pre-commit to production, and the multi-agent review workflow I use.

This is architectural concept (coined by John Ousterhout in The Philosophy of Software Design book) that pretty much contrasts modules with complex interfaces and simple implementations ( Shallow…

I paid for a popular bookkeeping tool and it worked well. But the UI kept getting slower, and I wasn't using its reporting, so I had no real view of my numbers. So I did what I usually do: I scoped a…

I’m a huge iOS Shortcuts wiz but recently I feel like Apple is making the shortcut-building experience worse and worse, especially when you’re building long Shortcuts. Because of that, last Friday I…

Making RUST-RL years ago I struggled for a long time trying to get grammar right in the message log. I made some a(foo) function that appended a or an before the word and it ended up being right some…

I like MAJOR.YEAR.WEEK[.PATCH]. SemVer’s major number is too important to lose to know if something is breaking or not, but all the other numbers are pretty meaningless. Knowing what date something…

In the previous post we looked at how Rust's speed of static analysis opened the door for non-PHP languages to analyze PHP codebases. What influence did it bring upon the PHP world? How can we - PHP…

Use NVIDIA Elements lint rules, MCP tools, and CI checks to catch component and design-token mistakes in AI-generated UI.

Edit Xcode projects from the terminal with xcodeproj, xcprojformatter, and the new JSON format

A couple of months ago I started porting a lot of my apps from separate git repos to the td repo where my linux distro is located. The two main ones were my mail and news client, which were renamed…

The first three AudioRouter posts talked about how the project got built and what it does. This one is about the part I get asked about the most when I show it to other developers: the backend. How a…

.talks-filters { margin: 2rem 0; padding: 1.5rem; background: var(--code-bg); border-radius: var(--radius); } .filter-group { margin-bottom: 1rem; } .filter-group label { font-weight: bold; display:…

Learn how I use AI-assisted development to understand, ship, and verify a real fix.

Posted on 2026-10-15 - Updated on 2026-10-17 Recently, I received a used HumanWare BrailleNote Apex BT 32 from the United States. This blog post is a collection of personal notes about connecting the…

Sometimes the biggest contributor to latency isn’t processing or network time. It’s waiting for work to start. I’ve got a talk coming up at P99 Conf (Oct 21-22) about managing correctness in…

You can clear the backlog of your open-source projects with AI now. It’s really great at reproducing bugs, implementing reasonable features, adding the tests you never had time to write, and…

My personal CSS wishlist for Interop 2027, from scroll-driven interfaces and better layouts to smoother transitions and customizable form controls.

Part of the reason AI is so appealing is that it increases productivity. Lots of developers do not realise that they can increase their productivity significantly without AI!

A bearer token tells your Rails app who's at the door, not which records an agent may touch. Reusing Pundit, rolling back denied writes, chaining the audit log.
