Wild performance tricks
Last week I had the pleasure of attending RustForge in Wellington, New Zealand. I gave a talk titled “Wild performance tricks”. You can watch a recording of my talk . If you’d prefer to read rather than watch, the rest of this post will cover more or less the same material. The talk shows some linker benchmarks, which…

Dear GitHub: no YAML anchors, please
This was a good thing . YAML anchors in GitHub Actions are (1) redundant with existing functionality, (2) introduce a complication to the data model that makes CI/CD human and machine comprehension harder, and (3) are not even uniquely useful because GitHub has chosen not to support the one feature (merge keys) that…

Why haven't local-first apps become popular?
Offline-first apps promise instant loading and privacy, but in practice, very few apps get offline support because getting sync right is surprisingly hard.

Easy Forth (2015)
This small ebook is here to teach you a programming language called Forth. Forth is a language unlike most others. It’s not functional or object oriented, it doesn’t have type-checking, and it basically has zero syntax. It was written in the 70s, but is still used today for certain applications .

Vibe coding cleanup as a service
The rise of AI-powered coding has created an unexpected market: cleaning up the technical debt from prompt-generated software. Here's why 'Vibe Coding cleanup' is becoming a legitimate service category and what it means for the future of software development.

Configuration files are user interfaces
We have all been there. Your software keeps growing and you feel the need to make it customizable. It is too soon for a full-blown UI with all the bells and whistles, so your pragmatic instinct suggests a text-based configuration file. Yes, that’s exactly it! You rejoice knowing the software’s configuration will be…

I uncovered an ACPI bug in my Dell Inspiron 5567. It was plaguing me for 8 years
Imagine you close your laptop lid to put it to sleep, but instead of pausing, it reboots. Not every time, just often enough to be infuriating. You try to save your work, but the machine decides to start over.

Scream cipher
You've probably heard of stream ciphers, but what about a scream cipher 😱? Today I learned there are more “Latin capital letter A” Unicode characters than there are letters in the English alphabet....

Implicit ODE solvers are not universally more robust than explicit ODE solvers
A very common adage in ODE solvers is that if you run into trouble with an explicit method, usually some explicit Runge-Kutta method like RK4, then you should try an implicit method. Implicit methods, because they are doing more work, solving an implicit system via a Newton method having “better” stability, should be…

Why do we keep gravitating toward complexity?
The Great Pyramids took decades to build. It was a monumental feat of human ingenuity and collaboration. Today, we software developers erect our own pyramids each day - not from stone, but from code. Yet despite far more advanced tools, these systems don’t always make the experience better. So why, when KISS (Keep It…
