Your CI should have one job: scheduling.

Several jujutsu commands require a revset.

pdsfs is a tool that mounts atproto PDS repositories as a FUSE filesystem.

There are a lot of reasons to use jujutsu, but this post is not about that.

At my last workplace, I wrote transpilers (or just compilers if you prefer) from mainframe languages (COBOL, JCL, BASIC etc.) to Java (in Rust!).

I use ssh a lot.

tbsp (tree-based source-processing language) is an awk-like language that operates on tree-sitter syntax trees.

I regularly switch between exactly two things while working, a "current" and an "alternate" item; a lot of tools I use seem to support this flow.

I cobbled together a journaling system with {neo,}vim, coreutils and dateutils.

Git worktrees are great, but they fall behind the venerable git checkout sometimes.

Minimizing your keyboard layout is a slippery slope.

I took interest in the Egyptian rendition of the afterlife recently.

Earlier this month, I decided that I would laugh at Indian customs in the face by building a split-ergo mechanical keyboard from scratch rather than purchasing a Moonlander.

Tree-sitter queries allow you to search for patterns in syntax trees, much like a regex would, in text.

Flakes are very handy to setup entirely pure, project-specific dependencies (not just dependencies, but build steps, shell environments and more) in a declarative way.

I have been working on an editor for the One Bit Image file format in Rust and SDL2.

Earlier this week, I began migrating my repositories from Github to cgit.

I have been eyeing operating systems with functional package managers for a while now, aka, NixOS or Guix.

You've read a lot of posts about the shortcomings of the Go programming language, so what's one more.

Rust's type system is Turing complete: FizzBuzz with Rust Traits A Forth implementation with Rust Traits It is impossible to determine if a program written in a generally Turing complete system will ever stop.

This post contains a gentle introduction to procedural macros in Rust and a guide to writing a procedural macro to curry Rust functions.

I've always been an admirer of pixel art, because of it's simplicity and it's resemblance to bitmap font design.

Last weekend, I was tasked with refactoring the 96 unit tests on ruma-events to use strictly typed json objects using serde_json::json!

I am not an expert with fonts, but I do have some experience ^exp, and common sense.

I learnt about termux from a friend on IRC recently.

My 4th semester involves ARM programming.

This piece aims to highlight (pun intended) some of the reasons behind my color free editor setup.

After going through a bunch of static site generators (pelican, hugo, vite), I decided to roll my own.

Decided to do one of these because everyone does one of these.

I finally got around to installing Void GNU/Linux on my main computer.

Glyph Bitmap Distribution Format is no more, as the creators of Pango, one of the most widely used text rendering libraries, announced their plans for Pango 1.44.

Onivim is a 'modern modal editor', combining fancy interface and language features with vim-style modal editing.

a couple of nifty tricks to help you copy-paste better: reselecting previously selected text (i use this to fix botched selections): gv " :h gv for more " you can use `o` in visual mode to go to the `Other` end of the selection " use a motion to…

Often times, when I run a vim command that makes "big" changes to a file (a macro or a :vimgrep command) I lose my original position and feel disoriented.

Bash is tricky, don't let your editor get in your way.
