Android Kernel Compilation Guide

This gist is intended to assist beginners, like myself, in getting started with Android Kernel Compilation. Please note that while I'm sharing my setup and process, this guide may not be entirely accurate, and I welcome suggestions from experienced developers to improve it.

Installing Build Tools

I am on Arch, so I will be using pacman to install the base-devel package group.

sudo pacman -S base-devel

On a Debian based distro, you can use apt and install the build-essential package.

Use Your SSH Agent in a Crontab

Getting access to SSH inside a Crontab is often a problem for many as the environment in which your cron runs is not the same as your normal shell. Simply running ssh-add will not allow you to use your SSH Agent inside your crontab. Follow the below guide to setup your crontab to use your ssh-agent:

Usage

Install Keychain.
Add the following to your ~/.zlogin file which will be invoked on each login. This will allow your crontab (and normal shell) to use your ssh keys and bypass needing to punch in your password each time you need SSH. This will also span across multiple sessions and shells.

Conventional Commit Messages

See how a minor change to your commit message style can make a difference.

Tip

Have a look at git-conventional-commits , a CLI util to ensure these conventions and generate verion and changelogs

Supercompilation is a deep program transformation technique due to V. F. Turchin, a prominent computer scientist, cybernetician, physicist, and Soviet dissident. He described the concept as follows [^supercompiler-concept]:

A supercompiler is a program transformer of a certain type. The usual way of thinking about program transformation is in terms of some set of rules which preserve the functional meaning of the program, and a step-by-step application of these rules to the initial program. ... The concept of a supercompiler is a product of cybernetic thinking. A program is seen as a machine. To make sense of it, one must observe its operation. So a supercompiler does not transform the program by steps; it controls and observes (SUPERvises) the running of the machine that is represented by the program; let us call this machine M₁. In observing the operation of
