Bespoke solution to monitor power outages at home

When I came home from a 5-days family trip this summer I immediately realized power was off in our flat. The main switch in the electricity panel was down together with one other additional switch. Everything appeared to have happened a few days before we arrived, so a few things in the fridge were ruined and most of the freezer contents had to be discarded. This was despite the fact we have relatives living close by with an emergency set of keys but, as we were completely unaware of the events, we couldn’t ask them to go check.

I thought about what happened and...

Neurodivergence and accountability in free software

In November of last year, I wrote Richard Stallman’s political discourse on sex, which argues that Richard Stallman, the founder of and present-day voting member of the board of directors of the Free Software Foundation (FSF), endorses and advocates for a harmful political agenda which legitimizes adult attraction to minors, consistently defends adults accused of and convicted of sexual crimes with respect to minors, and more generally erodes norms of consent and manipulates language regarding sexual harassment and sexual assault in his broader political program.

In response to this article, and on many occasions when I have re-iterated my position on Stallman in other contexts, a common response is...

Rust for Linux revisited

Ugh. Drew’s blogging about Rust again.

– You

I promise to be nice.

Two years ago, seeing the Rust-for-Linux project starting to get the ball rolling, I wrote “Does Rust belong in the Linux kernel?”, penning a conclusion consistent with Betteridge’s law of headlines. Two years on we have a lot of experience to draw on to see how Rust-for-Linux is actually playing out, and I’d like to renew my thoughts with some hindsight – and more compassion. If you’re one of the Rust-for-Linux participants burned out or burning out on this project, I want to help. Burnout sucks – I’ve been there.

The people working on Rust-for-Linux are incredibly...

So you want to compete with or replace open source

We are living through an interesting moment in source-available software.1 The open source movement has always had, and continues to have, a solid grounding in grassroots programmers building tools for themselves and forming communities around them. Some looming giants brought on large sums of money – Linux, Mozilla, Apache, and so on – and other giants made do without, like GNU, but for the most part if anyone thought about open source 15 years ago they were mostly thinking about grassroots communities who built software together for fun. With the rise of GitHub and in particular the explosion of web development as an open platform, commercial stakeholders in...

text coordinate systems

Interesting discussion of some of the subtleties which come up when writing code to display and manipulate text:
https://zed.dev/blog/zed-decoded-text-co...te-systems
Much of this echoes Finseth's classic book on implementing emacs-style editors, but with updates to reflect our Unicoded world.
(Many people will avoid dealing with these issues by simply dropping in whatever text widget their favorite library provides, but I enjoy cooking from scratch.)

Однажды китайский ученый Ли Хунь Янь обнаружил некоторую незначительную, однако, существенно отличающуюся от фона корреляцию между количеством псилоцибина потребляемого корфуцианскими медузами и характером передвижения оных по стенкам четырехсотлитровго шарообразного аквариума, установленного в лаборатории по случаю празднования сто второго полугодичного затмения от начала новой эры Сингулярного Прорыва. Недолго думая, Ли Хунь Янь приделал к щупальцам медуз источники излучения в видимом диапазоне но с разной длинной волны, заснял весь процесс шестью камерами с 48 часовой выдержкой, симметрично расставив последние вокруг сосуда, где резвились подопытные и через неделю собрал прелюбопытнейший материал, который, в свою очередь, лег в основу фундаментального труда, ныне известного, как теория полутретичных n-многообразий простой метрики Ли Хунь Янь, с которой (с некоторыми упрощениями и оговорками) я, по мере сил, постараюсь познакомить любопытного и пытливого читателя.
