UE5 on Arch Linux

Just some personal in order to make Unreal Engine 5 compile on Arch Linux (25th of June 2022).

Don't even bother trying to make the marketplace run. You gotta do that shit under Wine (Lutris is great for auto-setup) and copy assets over to your Linux drive.

Dependencies:

sudo pacman -S dotnet-sdk xdg-user-dir clang make git

Rotate Official Raspberry Pi 7" Touch Screen

Shows how to easily rotate (in this case invert to make orientation correct within a case) the Raspberry Pi 7" Touch Screen.

This will also update the calibration for the touch screen so it will work correctly.

Based on example from https://manual.os-js.org/v3/guide/framework/#react

Very basic chat application:

Uses a custom websocket server
Uses React to render UI
Uses event subscription model to handle websocket messages

THIS IS JUST FOR DEMONSTRATION PURPOSES

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.
