Raspberry Pi Setup Guide

This guide will use either a macOS or an ArchLinux base system, to prepare a microSD card with Arch Linux for Raspberry Pi.

If someone managed to do the initial setup using Windows, please let me know, so I can add to this guide.

This guide will be verbose at times for some simple tasks. This is intended to help people just starting out, so it's not confusing. If something confuses you, let me know and I'll try my best to answer it.

Restore Seeed Studio XIAO Bootloaders WITHOUT A PROGRAMMER POD (CircuitPython 'install' method)

IMPORTANT CAVEAT

** XIAO nRF52840 may lose UICR (User Information Configuration Register) default configuration regarding NFC pads and NFCT functionality: it may get 0xFFFFFFFE (LSB = 0) instead of default/reset 0xFFFFFFFF (LSB = 1) value, leading to some sort of CONFIG_NFCT_PINS_AS_GPIOS written in protected bits. ** If NFCT functionality is not needed, then you're good to go.

For it to change, use a J-TAG SWD pod and perform:

# 1. Erase all
    
 nrfjprog --eraseall

The Death of the User Interface

TL;DR: We're witnessing the end of graphical user interfaces. AI agents like Claude Code are eliminating the need for windows, menus, and clicks, replacing them with natural language. The computer is finally learning to speak human, not the other way around.
