Setup

This code is a direct copy of the code found on the Express.js site under Getting Started. I just followed installing and hello world from there to get a basic server up and running.

Turing Technical Network

Hardware

• So it's been mentioned that Turing upgraded to a fiber network. Can you tell us more about that?
• What Wi-Fi hardware does Turing use?

Troubleshooting

• I remember back when I was at Turing the network was notoriously known for being slow, dropping connection, etc.
  • What was the main issue there and how was it solved?
• What steps did you have to take in order to narrow down the problem?

Learn You a Turing for Great Good!

It’s hard to keep track of everything you’re learning

• Once a day, try and recap what you learned that day; write about it!

• Every module, recap the module
• Keep your "Turing environment" clean and organized

Presenters & Decorators

Decorators

Thus, decorators are a perfect example of the Open/closed principle, in which an object is "open for extension" but "closed for modification"; you should be able to add new behavior to application without changing it's underlying source code. If any of this is a bit hard to swallow, I would
