Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

###Array ####Definition:

  • Stores data elements based on an sequential, most commonly 0 based, index.
  • Based on tuples from set theory.

# where n is ALPHABET.length.
# Based on pseudocode from

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

# remap prefix to Control + a

* Get human readable time difference between 2 dates
* Return difference between 2 dates in year, month, hour, minute or second
* The $precision caps the number of time units used: for instance if
* $time1 - $time2 = 3 days, 4 hours, 12 minutes, 5 seconds
* - with precision = 1 : 3 days
* - with precision = 2 : 3 days, 4 hours
You can’t perform that action at this time.
