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)

/*
  Incredibly simple Node.js and Express application server for serving static assets.
  
  DON'T USE THIS IN PRODUCTION!
    It is meant for learning purposes only. This server is not optimized for performance, 
    and is missing key features such as error pages, compression, and caching.
  
  For production, I recommend using an application framework that supports server-side rendering, 
    such as Next.js. https://nextjs.org

ECE Linux SSH + VS Code Setup Guide

How to set up SSH for ECE linux "the right way". No VPN is required to SSH into ECE linux. Notably, with this setup:

• Skip eceterm completely and go directly to eceubuntu/ecetesla - you only need to type the SSH command ONCE (and enter your password ONCE).
• Configure VS Code to work over SSH. Edit remote files while maintaining your VS Code features like Intellisense, syntax highlighting, themes, etc.

Skip to the bottom of the document for a summary (TL;DR).

Disclaimer: I have only tested on macOS. It should work fine for *nix systems, but not sure about Windows. The instructions are up-to-date as of the last update of the Gist. Some Windows-specific notes are included in some sections thanks to feedback from classmates using Windows.
