Computer Literacy for Geosciences

Draft TOC for a practical introduction to computing for Geosciences (most of it is probably applicable to other non-Computer Science fields)

The course should be agnostic towards specific platforms or products - Presented techniques should always cover the three main OSs (Win, Mac, Linux), and program code should be given in multiple languages (e.g. Python, R, JavaScript)

🟊 marks sections that can easily be skipped or moved to advanced courses

Arch Linux installation guide

Hi there, this is a guide to install Arch Linux on your computer. I decided to write a guide because I find most other guides to be either too minimalistic or they have you set up some parts of the system in strange ways.

This guide is reference material for myself, as well as for other people who would like to install Arch for the first time.
