A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

Create your library

Initialize project npm init -y

Create esm module ./src/esm/my-lib.js

function addNumber(value, value2) {
  return value + value2;
}

export { addNumber };

Emulating a Raspberry Pi with QEMU

Goal: Emulate a Raspberry Pi with QEMU in order to run the Raspbian O/S (based on Debian Linux).

The current setup is not ideal. For one thing, the maximum RAM allowed using the "versatile-pb" firmware is 256 Mb. In addition, only the most basic peripherals, a keyboard and mouse, are supported.

A number of articles have been written on this topic. Most are outdated, and the few recent ones are missing key information.

DevOps started out as "Agile Systems Administration". In 2008, at the Agile Conference in Toronto, Andrew Shafer posted an offer to moderate an ad hoc "Birds of a Feather" meeting to discuss the topic of "Agile Infrastructure". Only one person showed up to discuss the topic: Patrick Debois. Their discussions and sharing of ideas with others advanced the concept of "agile systems administration". Debois and Shafer formed an Agile Systems Administrator group on Google, with limited success. Patrick Debois did a presentation called "Infrastructure and Operations" addressing
