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.

Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled. (The Terminal commands I provide here assume that the drive is named Untitled. If the drive isn’t named Untitled, the procedure won’t work.) Make sure the El Capitan installer (or at least a copy of it), called Install OS X El Capitan.app, is in its default location in your main Applications folder (/Applications). Select the text of the following Terminal command and copy it. sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction Launch Terminal (in /Applications/Utilities). Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return. Type your admin-level account password when prompted, and then press Return. You may see the message “To continue we need to era

#Meteor and Self-hosted Infrastructure

Meteor is an eye-opening JavaScript framework that runs on both the client and the server, giving developers a revolutionary take on software engineering. If you are not familiar with Meteor, I urge you to visit their website.

##An overview

In this brief gist, I am going to discuss the process of setting up a server (in my case, a VPS) to host Meteor applications.

My experience with Meteor has been brief, however it has not taken much demonstration for me to realise the significance of this stellar framework. Let's jump right in!
