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.

Generate a GPG Key and revocation cert per http://www.gnupg.org/gpg/en/manual.html:

gpg --key-gen
gpg --output revoke.asc --gen-revoke <my user ID or email>

Once gpg key in keyring we can encrypt and decrypt files.

Validate and run a state when a valid GitHub hook call has been received from salt-api

Idea is that we can setup salt-api to receive hook call from GitHub, and configured run stat.sls only if the request HMAC signature matche is successful.

Unfortunately most documentation says to deactivate salt-api hooks authentication (i.e. webhook_disable_auth: True) which is not a good idea.

This Gist is about finding a way to declare which state to run based on data GitHub sends on push hook. But ONLY if the request is valid.

Skeleton defines desired logic, see reactor_github_push.py below.

	public class MockTweeterApi extends TweeterApi{
	public MockTweeterApi(Retrofit retrofit, LocalDataCache dataCache, Scheduler mainScheduler) {
	super(retrofit, dataCache, mainScheduler);
	}

	@Override
	public Observable<UserProfile> login(String username, String password) {
	return Observable.just(new UserProfile(username, password))
	.observeOn(mainScheduler);
	}

	#!/bin/bash

	sessionPWD="/home/$USER/";
	sessionName="new-session"; #must be same as filename
	#check if already created
	cd ${sessionPWD};
	#create SESSION
	tmux new-session -s ${sessionName} -n vim -d
	#first window 1: vim
	tmux send-keys -t ${sessionName} 'vim' C-m

	make.numeric <- function(data, x) {
	for (i in x) {
	data[ , i] <- as.numeric(data[ , i])
	}
	data
	}



	make.char <- function(data, x) {

	minetest.register_craft({
	output = "special:cleaner",
	recipe = {
	{ "", "wool:blue", "" },
	{ "default:steel_ingot", "default:steel_ingot", "default:steel_ingot" },
	{ "wool:white", "wool:white", "wool:white" },
	}
	})

	Intellectual property
	4 types of protection
	1. patent -compositions of matter, devices
	2. copyright - original expression (including software)
	3. trademark - source id/consumer goodwill
	4. trade secret - valuable, secret business

	What is copyrightable?
	-original works, including software
	-default rule is authorship = ownership (unless it's a work made for hire for your employer)
