geometric_algebra VS excalidraw

I got sucked down a Geometric Algebra rabbit hole a few months ago, which seems like a remarkably concise and intuitive way to work in a very wide variety of geometries, including 2D, 3D, 4D+, non-euclidean etc. I've wondered if GA would make a good foundation for a physics engine...

There are a few small rust libraries that look interesting [1][2], but none with a lot of traction.

Has anyone looked into this?

The GA community in general is very small. So yes, tooling could be better, but IMO that is not even the problem. The lack of understanding how to use it is, because GA is not explicitly taught in schools or universities.

I have written a compiler which generates SIMD ready code for the desired GAs. You can then use that output as a normal library for your application.

However, Notion and Obsidian can only help you write documentation. Well, how about some visuals? Let's talk about Excalidraw.

Fun fact: I used GA in Excalidraw, and it's still powering some of the interactions! https://github.com/excalidraw/excalidraw/blob/master/package...

I was happy to find out recently that there is a way to make Mermaid diagrams WYSIWYG / drag and drop editable that the open source https://excalidraw.com has and did I mention it's open source!? With a LLM, you can go full loop back to Mermaid again after a few rounds of manual editing. "What a time to be alive!"

I'm working on a personal project and found myself looking for an alternative to Postman/Insomnia this morning. This made me realize i've been using the same tools for so long for work (mobile development, finance) that this project may be a good time to try out some new things.

Here are a few tools that i've been using lately that I really enjoy:

https://pocketbase.io/ - A dead-simple self-hosted firebase/supabase-like "backend in a box" using golang and sqlite. So far i've been really impressed. I've gone the route of extending the base offering with more go code and am really enjoying the experience.

https://excalidraw.com/ - An open source whiteboarding tool. Slick to use and after learning some keybinds I've gotten pretty fast at throwing together diagrams to explain things to people on my team. The killer piece though is that the filetype is just json, so I can source control my diagrams. Even better, their "export to png" function has a box to embed the json data _into_ the png, allowing me to slap the diagram in places that only accept images (think confluence) and still be able to change the diagram later if needed. 10/10.

https://docs.gitlab.com/ee/ci/ - Gitlab's CI/CD toolset is really impressive, and I've gotten really intimate with it's deeper features over the past year. I'd be curious though to hear from someone who's familiar with it vs it's competitors.
