Auto switch audio output when a new Bluetooth device connects

Depending on the distro or DE/WM you are running and which programs you are using to manage your audio you maybe run into the hassle of having to switch audio outputs each time you connect a bluetooth device (headset/speaker). You can in fact make pulseaudio to autoswitch when connection is established and not do it manually.

To accomplish this you just need to check a condition in the default.pa config file located in /etc/pulse/ directory on your install and add the following line load-module module-switch-on-connect like in the code snippet below:

Enable `systemd` in WSL 2

**NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)**

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

To enable systemd under WSL we require a tool called systemd-genie
Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

Don't want to see package-lock.json and yarn.lock in your git diff? Here are two nifty aliases that hide these files from your diff.

alias gd="git diff -- :!package-lock.json :!yarn.lock"
alias gds="git diff --staged -- :!package-lock.json :!yarn.lock"

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>
