Easy and Automatic Local Area Network Git Mirroring via SSH

Mirroring Remote Origin

A git user may add or modify a remote in their repository via the git remote subcommand. Most commonly (e.g. in the case the user has cloned from a popular git service such as GitLab or GitHub) git repositories have a remote named origin which is the default remote operated on. We can add extra URLs that point to other servers hosting a copy of the repository via git remote set-url --add origin <url>.

Alternatively, one can also manually edit .git/config in the root of the repository. An example of what may be in the config regarding the remote origin is

[remote "origin"]
  url = [email protected]:<user>/<repo_name>.git
  fetch = +refs/heads/*:refs/remotes/origin/*

Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.

Uses git sparse checkout features to git clone only a given directory path within a repo.

Usage

Provide a GitHub tree-URL (a URL to a specific directory on a branch) as the only argument. Currently this only supports sparse checkout from GitHub.

Example: git clonedir https://github.com/GoogleChrome/chrome-extensions-samples/tree/mv3-migration-snippet/mv2-archive/api/messaging/timer

`git` Subcommand Note

If you have custom executables named as git-* in $PATH, git will automatically detect and offer these commands as subcommands. Therefore if you place git-clonedir in your $PATH (e.g. /usr/local/bin/) then you can also run it as git clonedir.

These are the sample input files in $PWD for the below examples:

i3-focus-skip-tabs

This parses the i3 workspace tree from the i3 IPC to execute focus commands on the outermost tabbed container that has 1+ siblings. If such a container is not found in the hierarchy up from the focused window to the root container then this will call a regular focus command. In theory this script can take any valid arguments that the i3 command focus takes (e.g. prev and next, etc.), however it has only been tested with leftandright.

The idea is this will move focus between the highest level containers without requiring several focus parent commands if working with highly nested containers.

Demo

The following video demo is running with the following keybinds, i.e. the "normal" keybind to change focus instead runs this script with super+alt+(left/right) being a fallback to normal focus (left/right.
