PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

# Windows (receiver) side:

# Linux (transmitter) side:
pactl load-module module-null-sink sink_name=remote

// This is a basic Swift function that allows for incoming system audio (like the microphone or USB input) to be 
// played to the system output. It uses the modern Swift syntax for setting up and using RemoteIO Audio Units. 
// Of course, before running this function, you would have to setup your AVAudioSession with the playAndRecord category, 
// as well as whatever other options you might like. This is just a barebones function that demonstrates the capability 
// and you should implement some better error handling and respond to audio session route changes or interruptions. 
// I've only created this gist because even though it seems like it would be a simple thing, there is essentially 
// zero documentation on anyone trying to do this on the entire internet, and if there was any, it was basically 
// ancient and using Objective-C and outdated APIs. Now with this I hope someone can use it to avoid the pains of 
// having to use AVAudioEngine and understand how to setup RemoteIO Audio Units in Swift just

# DO NOT PUT THE WIFI DONGLE IN THE DEVICE BEFORE MENTIONED EXPLICITLY BELOW

# Brief note, after this the UI will not show the usb dongle, 
# the wifi does work and I get an IP address, so all works,
# but I don't go into detail of making it show on the Raspbian UI.
# (for this purpose I don't care about the UI)

# For the use of this I connected my device to an ethernet connection and through the Router could see the IP which I can SSH into.

## STEP 1: Prepare machine and install packages needed

GitHub and Git are not just for writing programming code. They can also be an effective tool for writing articles and books. Matthew McCullough has written a quick guide to writing books in lightweight formats. This article will be folded into this Teaching repository over the coming months.
