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.

Data Structure Basics

###Array ####Definition:

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

Github provides no facility to do this via the UI. This is sad, because it would be extremely useful in order to draft something before publishing it. It would also be trivial for them to implement. Never mind; here's how to do it manually:

Get the "Clone this Gist" text from the left-hand side of the private Gist, e.g. https://gist.github.com/b9cc265982870c091a1e.git, and extract the ID b9cc265982870c091a1e.
Go to https://gist.github.com/ and create a dummy new public Gist.
Get the "Clone this Gist" text from the left-hand side, e.g. https://gist.github.com/8270253.git, and extract the ID 8270253.
git clone [email protected]:b9cc265982870c091a1e tmp-dir && cd tmp-dir && git push -f [email protected]:8270253.git

Hostnames

change both the computer's local host name and sharing name by: ( via here )

On your Mac, choose Apple menu  > System Preferences, then click Sharing.

Click Edit, then enter a new local hostname.
