// Remarks:
// *  Implements composite writer mutex and seqlock in a single word-sized lock.   
//    Allows optimistic reading and pessimistic writing.
//    Readers don't write to shared synchronization metadata, which helps avoid
//    coherence traffic.  Readers must tolerate observing inconsistent state, however.  
// *  Writer mutex is based on LIFO-CR lock from http://arxiv.org/abs/1511.06035.

Nix vs Guix

These are notes to the stream: https://youtu.be/S9V-pcTrdL8

Some notes

• We are not aware of a lot of GNU software available to us.
• Seems that Guix more hacker-friendly/explorable.

Doom Emacs setup

Doom-Emacs is a Emacs framework, Emacs is a huge software with multiple packages and ways to do everything, doom-emacs try to make that a little bit easier for most new users offering a simpler way to install and manage most important packages and configs, under the hood it's a lot of elisp code that install most useful Emacs packages, manage packages state, improves performance with multiple tweaks and offer all of that in a easy opt-in/out way to final users via modules. Doom uses under the hood the evil-mode package, which is a package that tries to bring Vim's commands and motion to Emacs, so knowing vim helps a lot how to use Doom emacs, although you don't need to understand vim to start using it.

Pre-requisites

• Emacs 27.1+ (Mac users: brew install emacs-plus@28 --with-native-comp), more details here.
• [ripgrep](https://github.com/Bur
