A comprehensive writeup of setting up offlineimap, mutt, and notmuch.

Being a bit older it does not consider isync/mbsync nor neomutt - but the ideas and logic behind decisions is explained very well.

Many many Linux softwares. Mostly useful as an overview for someone looking for a software in a specific area of computing (audio engineering, writing, database editing, programming, ..) since they are nicely sorted and allow an overview of FOSS alternatives to various software needs.

Fully localized, one of the rare guides using neomutt instead of mutt as well as msmtp for mail relay.

issue management directly integrated into git repository and invoked as if part of the git suite. Contains integration for importing/exporting (and even syncing automatically I believe) to GitHub/Lab.

A review of Tailscale, "a secure network that just works".

Uses wireguard to create an encrypted tunnel between all your devices. Automatically takes care of NAT, DNS, and similar.
Essentially makes it really easy to set up your true private network within the wider one.

Also comes with 'taildrop' which mimics airdrop to easily transfer any files between your devices,
but do so without any involvement of external cloud services and completely encrypted.
