True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

Debloating Nox

Nox, despite being the most feature-filled Android emulator, has a lot of negativity surrounding it due to their antics when it comes to making income off of their program. It is known for running repeated advertisments in the background, calling home and passing along system information (outside of your Android instance) as well as a vast amount of potentially sensitive data in an encrypted payload back to their multitude of servers. With the following preventitive measures, we can stop a majority of this happening as well as greatly improve the overall performance.

1. Download and Install a fresh copy of Nox. The latest version is fine (for now). If you already have it installed, that is fine too. No need to reinstall.

2. Enable Root Mode on Nox by clicking the gear icon and then checking the Root Startup box.

3. Install a new Launcher from the Play Store. ANYTHING but Nox's default. I suggest [Nova Launcher](https://play.google.com/s

Tar Usage / Cheat Sheet

Compress a file or directory

e.g: tar -czvf name-of-archive.tar.gz /path/to/directory-or-file
