One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

In Tools | Options | Keyboard...

1. Add CTRL+W as a Global shortcut for Window.CloseDocumentWindow
2. Remove the CTRL+W shortcut for Edit.SelectCurrentWord

The caveat to this is if you are used to using CTRL+W to select the current word. If you do, find another shortcut that works for that.

ABOUT

about:config settings to harden the Firefox browser. Privacy and performance enhancements.
To change these settings type 'about:config' in the url bar. Then search the setting you would like to change and modify the value. Some settings may break certain websites from functioning and rendering normally. Some settings may also make firefox unstable. I am not liable for any damages/loss of data.

Not all these changes are necessary and will be dependent upon your usage and hardware. Do some research on settings if you don't understand what they do. These settings are best combined with your standard privacy extensions (HTTPS Everywhere No longer required: Enable HTTPS-Only Mode, NoScript/Request Policy, uBlock origin, agent spoofing, Privacy Badger etc), and all plugins set to "Ask To Activate".

map()

Use it when: You want to translate/map all elements in an array to another set of values.

Example: convert Fahrenheit temps to Celsius.

var fahrenheit = [0, 32, 45, 50, 75, 80, 99, 120];

var celcius = fahrenheit.map(function(elem) {
