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 --------------------------------------------------------------------------- Useless facts ============= - 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. Useful facts ============ - 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? ``` About keyboardless editor Resources Readme AGPL-3.0 license Activity Stars 0 stars Watchers 0 watching Forks 0 forks Report repository Contributors Languages You can’t perform that action at this time.
