This friday (31 july) there will be scheduled maintenance of the suckless servers.

It's estimated this will take about 1 hour.

The mailinglist, website and source-code repositories will have some downtime.

Update: the update was performed on saturday (1 august). Everything should work again.

A GTK4 ssh-askpass in Zig

I run hardened Gentoo on my laptop, and most of the time I never touch ssh-askpass because I’m using -sk keys for most of the systems. There is one class of situation where I do need it, though, which is when a program wants an SSH key passphrase for a regular ED25519 key, but has no terminal to read it from. The usual case is go get, or the go toolchain in general, fetching a private module over SSH during a build that runs without a TTY. OpenSSH can’t prompt on a pipe, so it runs whatever SSH_ASKPASS points at and puts the passphrase prompt in a...

I Regret Migrating to Codeberg

My primary reason for leaving GitHub was not about a single feature or a single outage, but about the “enshittification” of the platform under Microsoft’s ownership. The web interface got rewritten into a sluggish pile of JavaScript that either broke things which used to just work, or made them so horribly slow that using them became a PITA. Beyond the technical decay GitHub had turned into de facto “public infrastructure” in much the same way that WhatsApp has, hosting the source code of a very large share of the world’s software and, through that, giving Microsoft a degree of leverage and surveillance over everyone’s projects, and by extension everyone’s...

AI in Linux

The role of AI tools (LLMs, mainly) in Linux is under discussion, or it was, until Linus Torvalds “put his foot down” in support of the use of AI in Linux kernel development.

I can identify two major ways in which AI is used for Linux kernel development: authoring code and reviewing code. There are, at the time of writing, just over 1,200 kernel commits with an “Assisted-by” tag, from September 2025 to the present, most of which indicate patches which were written or assisted by LLM tools.

The second important use of AI for Linux comes with a new code review...

Build a HTML5 game like Geometry Dash using Phaser 4 and TypeScript, with a simple custom physics engine

The cube in Geometry Dash always lands perfectly square. It's not rigid-body physics: the spin is purely cosmetic. The hitbox never rotates, and the game snaps the angle to 90 degrees on landing. I rebuilt it as an HTML5 game in Phaser 4 + TypeScript, with my own physics engine.

5 ошибок менеджера, внедряющего ИИ

Опустим мечты учёных и фантастов 1950-ых годов о создании кибернетического сверхмозга и перейдём к практике: начиная с 1960-ых, ключевым направлением применения Искусственного Интеллекта стала автоматизация процессов управления и принятия решений. Грубо говоря, программисты думали как заменить менеджеров. В итоге получилось наоборот: менеджеры думают как заменить программистов.
