Welcome to “stupid jj tricks”. Today, I’ll be taking you on a tour through many different jj configurations that I have collected while scouring the internet. Some of what I’ll show is original research or construction created by me personally, but a lot of these things are sourced from blog post, gists, GitHub issues, Reddit posts, Discord messages, and more.

In functional programming,
combinator libraries refer to a design style that emphasizes bottom-up program construction.
Such libraries define a few core data types
and provide constructors—functions that create initial objects—and combinators—functions that build larger objects from smaller pieces.

Combinators enable the programmer to use intuitive visual and spatial reasoning
that’s vastly more powerful than linear language processing.
As a result, solving problems with combinators feels like playing with lego pieces.

Every so often I come across a paper, blog post, or (occasionally) video that completely changes how I think about a topic in programming languages and compilers. For some of these posts, I can’t even remember how I thought about the idea before reading it—it was that impactful.

Games can be made in many different ways. Many games are made using big, general purpose game engines such as Unity and Godot. I enjoy using the Odin Programming Language combined with Raylib.
Odin is a C-like programming language and Raylib is library for drawing graphics, checking input and playing sounds. So it’s just a program that uses a simple library, no engine!
There are no objectively best ways to create games.

A lightning post on logic programming in Haskell to construct a workout weekly schedule given the set of exercises, days and constraints.

In this post, I talk about pleasant but seemingly minor features in personal sites

Most programming language ecosystems provide assert functions in their testing libraries but not Go's. Go's standard testing package follows a more direct and to-the-point approach.

Featureful zsh prompt.

Sales pitches are the only place where “self-serve dashboards" work. In the real world, it's a different story.

Why "business" people don't use metabase/power-bi.

Living specification of the IRC protocol. Does not include brand new behavior, just existing behavior present in IRC software and/or networks (new extensions are IRCv3's area).

soju is a user-friendly IRC bouncer. soju connects to upstream IRC servers on behalf of the user to provide extra functionality. soju supports many features such as multiple users, numerous IRCv3 extensions, chat history playback and detached channels. It is well-suited for both small and large deployments.

piku, inspired by dokku, allows you do git push deployments to your own servers, no matter how small they are.
