why did i write this? i don't know.
I’ve noticed the editor is full of bugs—I don’t know how to fix them myself—but yeah, my code is worse than ever.
-----------------------------------

how to launch?
* 1. git clone https://github.com/erqeon/mu
* 2. cd mu
* 3. cargo run --release
-------------------------------------------------

Send a pull request or issues if you're not too lazy, preferably through mu
---------------------------------------------------------------------------

- i came up with this project while reading an article about vim on wikipedia.
- mu, from the word "mouse".
- many programmers write scripts that automatically subscribe to people (most often in python).
- systems programmers go on about how writing code is a grueling struggle, even though they work at companies where they rake in huge paychecks (i hope they won't be replaced by ai).
- corporations parasitize free code (please do not use mit/apache licenses).
- corporations have drilled it into our heads that we should use open source absolutely for free, while forgetting how many nights developers spend fixing bugs.
- when steve jobs died, the whole world shouted about it; when Dennis Ritchie died, everyone remained silent.
- i’d love to work on open-source projects and be independent, but people usually only donate to giants like Linux or Vue.js, not to ordinary programmers.
- modern programmers have forgotten how to write simple, minimalist code; instead, their code weighs more than the game *Cyberpunk* (give him html,css,js, and he won't even be able to write basic code, when i visited the Vercel website—oh God, forgive us for our sins—my browser was lagging as if it were trying to run GTA 6).
- modern consumers think the industry depends on their opinion, although that is not the case (they post their photos every day and want people to be jealous—it’s just so low).
- the platforms are so lazy that they decided to restrict regular users from posting, lol.
- it is better to have a thousand loyal users than a billion soulless robots.

- I came across a post on Hacker News discussing Silicon Valley's fear that independent open-source programmers might create free AI alternatives.
  They might be right; personally, I think we need to ditch the Transformer architecture in AI—it consumes a huge amount of RAM.
- Mistral is trying to show the world that they’re building something new, even though they’re creating the same kind of monsters as OpenAI—LOL.

Is anyone reading this? Wanna bet $0 that Linus Torvalds won't read this code and the README?
