This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.
Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

| # How to use: | |
| # * run in PKGBUILD dir or pass path to PKGBUILD as argument | |
| # this will generate volatile source tree in $TMP (default: /tmp) and | |
| # generate source array and prepare_submodule() function to init them | |
| # * add local=1 env var to use src/ dir in PKGBUILD path instead of $TMP | |
| # * add remote=1 env var to update module past the pined commit hash |

Instalación ArchLinux: mkdir ArchLinux && pacstrap -c ArchLinux base linux-api-headers
Una vez iniciada sesion con systemd-nspawn -D ArchLinux (debe usar la opción -D solamente), debemos borrar los archivos /etc/securetty y /usr/share/factory/etc/securetty dentro del contenedor solamente, además de añadirlos al archivo /etc/pacman.conf del mismo, en la opción NoExtract. La línea sería la siguiente:
NoExtract = /etc/securetty /usr/share/factory/etc/securetty
The Linux kernel is written in C, so you should have at least a basic understanding of C before diving into kernel work. You don't need expert level C knowledge, since you can always pick some things up underway, but it certainly helps to know the language and to have written some userspace C programs already.
It will also help to be a Linux user. If you have never used Linux before, it's probably a good idea to download a distro and get comfortable with it before you start doing kernel work.
Lastly, knowing git is not actually required, but can really help you (since you can dig through changelogs and search for information you'll need). At a minimum you should probably be able to clone the git repository to a local directory.

| # This test script is a result of a discussion on AskUbuntu (https://askubuntu.com/q/1265756/66509 ) about using Intel MKL in Ubuntu | |
| # | |
| # Modern Ubuntu versions include Intel MKL libraries since Ubuntu 19.10 (such as https://packages.ubuntu.com/focal/libmkl-full-dev ) | |
| # and it is expected that this library may be used by some scientific applicaitons like Octave, Scilab and others. | |
| # | |
| # Test method: | |
| # 1. Execute this script with default mathematical libraries, save the results | |
| # 2. Install the Intel MKL library with `sudo apt-get install libmkl-full-dev` confirming its usage as default math libraries alternative | |
| # 3. Execute this script again after Intel MKL installation to compare the results |
