Guide to setting up raspberry pi's in 2022!

Setting up Pi's

To setup your Pi initially install using the imager, after selecting 64-bit os (lite or normal) go into the settings.

Make sure you:

  • set your hostname to what you want
  • allow SSH
  • set a password & username (I usually just leave the username as default)
  • setup a WLAN (if not using ethernet, and make sure to set your country)

A "course" on operating system fundamentals

Operating Systems

This document outlines many of the key aspects of operating systems, and provides resources to learn more about each part. There are a lot of things missing (i'm on human), but these are enough to get you up and running. The intention is to be able to understand how you go from electricity entering your PC to being at a login screen you can see.

Most of this is relevent to linux primarily because it's open source, so there's much more information available about it, but these principles are the same across systems they just may have different names for things.

Prerequisties

  • You know how to use a terminal

Finds True or False (and uncapitalized): (true|false|True|False)
