Hi! My name is Martí Homs Soler. I'm a Software Engineer, entrepeneur, tinkerer and writer.

This blog is my personal space, where I write mostly for myself to explain what I’m learning, clarify ideas, or document rabbit holes I fall into. You can find random thoughts and snippets of ideas under Blog.

You can find interesting tech stuff under Tech. It is mainly about personal software projects, NixOS, ergo-split keyboards and homelabbing, with the ocassional random note on here and there.

You can find some weird D&D-like OSR-adjacent stuff under RPG. Here is where I post about tabletop RPG mechanics, world-building, and random storytelling experiments.

Or just look around. You can finds some of my recent entries below.

My Plan To Become A Successful Indie Game Dev

Jul 12, 2026

The past few months have been a roller coaster. This post has been in the making for over three months (it was suppose to come out in June 2026). After some thoughts and some trial and error, I reached a decision. This post acts as my personal commitment to becoming a successful indie game developer and how my next 18 months look like.1 I think this post will greatly benefit to start by defining …

The Importance of Building Square Wheels

Oct 31, 2025

Inspired by Sphaerophoria’s channel description, Tsoding’s recreational programming and some of my own projects, but specially Goburin as of late, this post is about something that is frowned upon in the sofware industry and, frankly, sounds counterintuitive: re-inventing the wheel. In this topic about “useless work” I want to focus on an area that I believe is often barren and even more “useless”…

My new Flakes + Just setup

Oct 22, 2025

It has been a hot while since I wrote an entry in this blog., but I’ve been quite busy with some very interesting side-projects. And today I wanted to revise my nix project setup, and show what I’m using to develop Goburin, my hobby programming language. I’ll explain more in a future article and explain why I’m starting by bootstrapping it in assembly and then in Forth… But now on the actual topic…

Itreas Gate - Gygax 75 - Part 1

Jun 4, 2025

This project comes from a huge mix of ideas that have been bouncing around in my head, pushing me to finally dive in and create another world, but this time put as much of the process I can into writing. The blog posts may come sparsely and thin, I’ll try to update them as I write further, but keep in mind that I am aiming these posts to be for me by me. I’m re-imagining an existing world—called I…

Aliases problems with `nix-shell`+ `direnv`

Apr 30, 2025

When working in reproducible development environments, nix-shell and direnv form a powerful duo — more precisely nix-direnv. Combined, they allow per-project environments to be automatically loaded when entering a directory — no manual shenanigans needed. Nonetheless, one recurring pain point is the frustrating interaction between nix-shell, direnv, and Bash aliases. While developing this personal…

TwoOfUs - My Custom Keyboard & Layout

Apr 23, 2025

Recently. I’ve been dabbling once again into the ergo-split keyboard development/building rabbit hole and it came to mind that I haven’t written about the keyboard+layout that I’ve been using. My current keyboard needs have changed, and I started looking for interesting new avenues to pursue, like the 5-way switches I discovered when I stumbled upon this keyboard named Fulcrum and the amazing one-…
