Text showdown: Gap Buffers vs. Ropes
I have been working on a hobby project to reimagine the C core of Emacs in Rust. On this journey, I reached the point where I needed some way to represent the text of a buffer. The simplest approach is to just use a large string or array of lines. However these each suffer from poor performance as either the size or…

My personal C coding style as of late 2023
This has been a ground-breaking year for my C skills, and paradigm shifts in my technique has provoked me to reconsider my habits and coding style. It’s been my largest personal style change in years, so I’ve decided to take a snapshot of its current state and my reasoning. These changes have produced significant…

Forty years of programming
I am about to turn forty-six. This means I have been programming for forty years, half of them professionally. During most of that time, I used a "standard" setup with 104 keyboard, a flat mouse, and a sitting desk.

Speeding up the JavaScript ecosystem – The barrel file debacle
Many projects are littered with files that just re-export other files. These so called "barrel files" are one of the key reasons why JavaScript tooling is slow in bigger projects.

Calling Rust from Python
I recently watched GOTO conferences' talk Calling Functions Across Languages by Richard Feldman. I’m afraid I have to disagree with using the term 'language' in this context. It’s a no-brainer to call Java from Kotlin or Scala or to call Java from Kotlin. Hence, in the rest, I’ll use 'stack'.

Why is Debian the way it is?
Debian is a large, complex operating system, and a huge open source project. It's thirty years old now. To many people, some of its aspects are weird. Most such things have a good reason, but it can be hard to find out what it is. This is an attempt to answer some such questions, without being a detailed history of…

Subtraction is functionally complete
To be precise, IEEE-754 floating point subtraction is functionally complete . That means you can construct any binary circuit using nothing but floating point subtraction.

Thread-per-core
I want to address a controversy that has gripped the Rust community for the past year or so: the choice by the prominent async “runtimes” to default to multi-threaded executors that perform work-stealing to balance work dynamically among their many tasks. Some Rust users are unhappy with this decision, so unhappy that…

LLMs confabulate not hallucinate
Minor terminological nitpick. People often describe the LLM as ‘hallucinating’ information whenever it makes up information which seems like it should fit for a given query even when it is trivially false. While evocative, this isn’t actually correct terminology. We already have a perfect word for this precise…
