Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

• To enable systemd under WSL we require a tool called systemd-genie

• Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

A script to automatically export bookmarks from Firefox's SQLite database.

There does not seem to be a programmatic way to get Firefox to export its bookmarks in
the conventional HTML format. However, you can access the bookmark information directly
in Firefox's internal database, which is what this script does.

Always be careful when working with the internal database! If you delete data, you will
likely not be able to recover it.

In writing one’s own Base64 codec for the Cryptopals Crypto Challenge in Rust, one gets to a point where every chunk of four adjacent elements in an input vector has to be transformed into a chunk of three elements in an output vector.

That is, the string SSdt containing four ASCII bytes becomes the string I'm containing three ASCII bytes, and IGtp becomes  ki, and so on, so that SSdtIGtpbGxpbmcgeW91ciBicmFpbiBsaWtlIGEgcG9pc29ub3VzIG11c2hyb29t is decoded to I'm killing your brain like a poisonous mushroom.

I had a function to do this four-to-three downconversion but looping over the two arrays, lining up the indexes, the keeping track of magic threes and magic fours in my code gave me a headache as I worked through writing the following:

pub fn decode(s: &[u8]) -> Vec<u8> {
    let mut out: Vec<u8> = vec![0; s.len() / 4 * 3];
    for i in 0..ou
