CatHeap Games blog

Tech blog of an old grumpy developer.

Let’s pretend I dug out one of those 1990s “under construction” gifs here.

You can have a look at my CV if you’re into that sort of things, otherwise there will be blog posts linked in the sidebar navigation, and eventually free resources like repos, assets, music, etc.

Non-technical

You can listen to my music on Deezer or Spotify if you haven’t left that public toilet yet.

Contact

You can send me anonymous questions over at Tetratto. I’ll figure out how to add an obfuscated email address some day later.

About me / short Curriculum Vitae

Some middle aged guy in Europe who mostly works as “senior developer” and “architect”. Expert on nothing, curious about learning everything.

Currently retooling my skill set to game development and Rust overall.

Detailed CV might come in later when this site has more than 0.30000000004 pageviews per month.

Short CV

20 years of being a web developer.

From the most recent ones:

Rust, Bevy, embedded (self-learning)
presentation about low-level programming and PostgreSQL internals
video editing, tutorials
Kafka cluster management, PostgreSQL DBA tasks
dev env architecture, tooling, helper commands, troubleshooting
Grafana dashboards, custom Prometheus metrics exporting
SRE, bug hunting
Kubernetes and architecture around microservices
Node.js, Express + tooling
(long time ago) Python, Twisted, Django, Flask, uWSGI
(very long time ago) PHP, XML, XSLT
(u64::MAX long ago) BASIC and basics of x86 assembly

What can I do for you?

You can try to hire me, preferably to work in Rust on a part-time, permanent basis (~24 hours a week), or as a contractor.

I’m available to teach, give presentations, make text or video tutorials, write documentation.

I thrive when the overall direction is clear, I’m fine with specific tasks as long as there isn’t persistent micromanagement, I prefer some degree of freedom, and work well with complex problems that don’t have a singular right solution, e.g. optimizing production load and investigating complex, distributed issues like outages and slowdowns.

I prefer respectful, supportive environments with product owners who know what they want; and agile delivery (generally prefer kanban than sprints).

For now, contact me over at Tetratto. I’ll figure out how to add a proper contact form later.

Why start this blog

It’s been a while since I regularly updated a tech blog. The era of blogs feels long gone, even as I still find useful articles now and then; now more so than ever before with political propaganda and AI slop and AI slopaganda, blogs feel like a corrupted medium on its way out, like printed magazines.

That said, sometimes I have opinions, or want to share something that doesn’t neatly fit into a bluesky post or a github issue, and would require too much work to format into a youtube video, so hello Typst I suppose.

What to expect

Opinions and troubleshooting logs about Rust, Bevy, embedded hardware like ESP32 and Raspberry PI Pico/Zero, Kubernetes, game design, UI/UX/DX, and potentially Node.js/Vue and whatever else I end up using.

Propaganda

This blog is shameless self-promotion, and I encourage you to give me money in some way. I’ll consider getting hired, working as a contractor, or contributing to open source for a fee.

Where am I with Rust GUIs

Overview

I love the idea of Vue, but I don’t have the mental bandwidth to learn it properly, so to make HTML apps there’s a few options:

try to use Vue anyway
try to use Leptos or Yew which compile down to HTML+WASM+JS
try any of them with or without Tauri
dioxus compiles down to a HTML + Tauri app

There’s a few options for primarily GUI apps:

non-Rust Godot with potentially a Rust extension (lots of idle games in Godot)
egui + eframe to have a “plain” application
bevy + egui + bevy_egui to have Bevy take care of the window + offer a game engine if that’s what you want

bevyui bevy egui leptos - 20k gh tauri - 101k gh dioxus - 33k gh yew - 32k gh

Leptos pros

Actix/Axum server side rendering or something
Isomorphic - can write same style code to do server-side API endpoints

Dioxus pros

dx serve --platform android
fast rebuild and live reload of course

Not considered

cushy - not updated for a year
