There has been rather a lot of doomsaying (and perhaps astroturfing) lately about LLMs as the end of computer programming. Much of the discussion has been lacking nuance, so I’d like to add mine. I see claims from one side that “I used $LLM_SERVICE_PROVIDER to make a small throwaway tool, so all programmers will be…
Updated 2026-07-10 for the agent-teams era. Originally published September 2025. A subagent in Claude Code is a separate agent your session spawns to do a...
People say many things about entropy: entropy increases with time, entropy is disorder, entropy increases with energy, entropy determines the arrow of time, etc.. But I have no idea what entropy is, and from what I find, neither do most other people. This is the introduction I wish I had when first told about entropy…
Amazing as it may seem after all these years, there are still junior developers in the world. A few weeks ago at work we had a talk where senior developers (including me) were invited to spend around five minutes each talking about our personal software development philosophies....
While recently traveling to the U.S., I was completely locked out of my TD Personal Banking account. TD relies heavily on SMS-based two-factor authenticat...
Perhaps the most often repeated complaint about Rust is its slow feedback loop and long compilation times. I hear about it all the time; in Rust podcasts, blog posts, surveys, conference talks or offline discussions. I also regularly complain about it, being a Rust user myself!
Artificial intelligence is the biggest tech construction project in a century. Here's what that looks like.
Over the last decade, we’ve seen great advancements in distributed systems, but the way we program them has seen few fundamental improvements. While we can sometimes abstract away distribution (Spark, Redis, etc.), developers still struggle with challenges like concurrency, fault tolerance, and versioning. There are…
As part of my work toward an upcoming post about a lost piece of very obscure Mac history that has finally been found, I’ve been playing around with old Apple-branded SCSI hard drives made by Quantum and Conner in the 1990s. What I’m about to describe is already common knowledge in the vintage computing world, but I…
A developer's lament about Xcode's opaque errors, unreadable project files, and Apple's culture of pretending everything is fine.

Why does Space Station 14 crash with ANGLE on ARM64? 6 hours later…
I've started working on a new edition of Ruby Under a Microscope that covers Ruby 3.x. I'm working on this in my spare time, so it will take a while. Leave a comment or drop me a line and I'll email you when it's finished.

LLM agents make bad pairs because they code faster than humans think. I'll admit, I've had a lot of fun using GitHub Copilot's agent mode in VS Code this month.…
Previously I have covered a relatively obscure now-removed placeholder string in Android that doubles as an easter egg, the fictitious carrier by the name of El Telco Loco. But this time it is about methods and other parts of the publicly facing Android API that may generally be more humourous than they are useful…
Marcin ‘mbork’ Borkowski has a nice post showing us how he trims video clips from our beloved editor. Trimming clips is something I do from time to ti...
I’ve put together a 300+ page book with basically everything I learned the hard way over the last 10 years founding and working at several hardware startups. It started out as a self published work, but No Starch Press picked it up and it went through a very extensive editing process to make it even better.
At the beginning of 1996, Sierra On-Line was still basking in the success of the previous summer’s Phantasmagoria , the best-selling game it had ever published. With revenues of $158.1 million and profits of $16 million in 1995, the company was bigger and richer than it had ever been. In light of all this, absolutely…
How I built a simple portable audio player for my boy, summoning the spirit of the Gameboy
It's understandable why the guys who had big tech startup successes in the 90s and early aughts think that "DEI" is the cause of all their problems. Not understandable in the "gotta hand it to em" sense, but in the sense that it's not hard to follow the stupid mistake they all make.
Look, I'm an idiot. I know that, you know that, and the man on the moon knows that. Let's not get into why I'm an idiot; let's just accept that I have my peculiarities and you have yours. My idiocy is a quest to make sure all my portable electronics can recharge using USB-C. Modern smartwatches are tiny and they do a…
A lot of people say AI will make us all “managers” or “editors”…but I think this is a dangerously incomplete view!
Ever since I got AMD, Intel, and Nvidia graphics cards to run on a Raspberry Pi, I had a nagging question: What's the point? The Raspberry Pi only has 1 lane of PCIe Gen 3 bandwidth available for a connection to an eGPU. That's not much. Especially considering a modern desktop has at least one slot with 16 lanes of…
I have recently worked on making a web application out of my latest Rubik’s cube optimal solver . This involved building a rather complex C code base (with multithreading, SIMD, callback functions and whatnot) to WebAssembly via Emscripten , and writing a minimal amount of JavaScript and HTML for the frontend.
