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.

	var express = require('express');
	var stormpath = require('express-stormpath');
	var morgan = require('morgan');

	var app = express();
	app.use(morgan('combined'));

	stormpath.init(app, {
	client: {
	apiKey: {

	from pydispatch import dispatcher
	from stormpath.client import Client
	from stormpath.resources.base import SIGNAL_RESOURCE_CREATED


	def resource_created(signal, sender, data, params):
	"""Prints off some signal data when a resource is created."""
	print 'signal:', signal
	print 'sender:', sender
	print 'data:', data

	# This test is meant to test out Scenario 1: a lot of users are concurrently
	# creating accounts and then logging into a web service with Stormpath.
	#
	# This script will create 1,000 users total before exiting. This script should
	# be launched as many concurrent times as you want to emulate production
	# traffic.
	#
	# INSTALL:
	# To install this script, you need to have pip (for python) installed. Then run:
	#

	# This test is meant to test out Scenario 2: users logging into a group
	# protected page, refreshing their custom data, and saving it.
	#
	# This script will run the above operations 1,000 times in a row, and should be
	# launched as many concurrent times as you want to emulate production traffic.

	from uuid import uuid4
	from stormpath.client import Client

	STORMPATH_API_KEY_ID = 'xxx'

	# This test is meant to test out Scenario 1: a lot of users are concurrently
	# creating accounts and then logging into a web service with Stormpath.
	#
	# This script will create 1,000 users total before exiting. This script should
	# be launched as many concurrent times as you want to emulate production
	# traffic.

	from uuid import uuid4
	from stormpath.client import Client

	var async = require('async');
	var stormpath = require('stormpath');
	var uuid = require('uuid');

	// Modify these values for testing.
	var TOTAL_USERS = 10000;
	var CONCURRENT_REQUESTS = 10;

	var client = new stormpath.Client({
	apiKey: {

	##### CLEANUP
	# Unbind the default tmux command prefix, CTRL+b.
	unbind C-b
	#####


	##### PREFERENCES
	# Use CTRL+a as our tmux command prefix.
	set -g prefix C-a

	var express = require('express');
	var stormpath = require('express-stormpath');

	var app = express();
	app.use(stormpath.init(app, {
	apiKeyFile: process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'] + '/.stormpath/apiKey.properties',
	secretKey: 'some_random_long_string_here',
	application: 'https://api.stormpath.com/v1/applications/xxx',
	}));
