Requirements

A self-managed VPS or dedicated server with Ubuntu 24.04 running Apache 2.4.xx.
A registered domain name with working HTTPS (TLS/SSL). HTTP/2 and HTTP/3 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 or HTTP/3 in cleartext (non-TLS) mode.

Architecture

After multiple tries with apche2 recompiling with a different modules to support quic and http3, I simply run nginx container that will overtake only UDP traffic and forward it to the apache2 as http2 via TCP. So, no, it is not real "http3 apache2 support", but works pretty well and you do not need to change anything on your Apache2 sever.

Upgrade LineageOS with Magisk

WARNING: tested only on my setup (LineageOS 18.1 on instantnoodle), other setups may break and brick the device!

Step-by-step instructions (for reinstalling patched boot.img for Magisk):

upgrade LineageOS to the latest by the standard way in Android GUI (download + install + reboot)
if using not the latest Magisk: wipe old (possibly hidden) Magisk app then install the up-to-date one from the official Magisk github repo
~~install (git clone) payload_dumper from GitHub (in Termux or in an SSH session on the Android device) for the 1st time, or update (git pull) later~~
~~the Android terminal session: wget the same LineageOS nightly image installed in step 1 from https://download.lineageos.org/~~

ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Get a single character	`${VARNAME[index]}`

Fully automated setup of Ubuntu 20.04 on ZFS as root file system, optionally with LUKS and/or ZFS native encryption via single master password/keyfile and SSH unlock.
