#System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

	import os, json, subprocess

	file = open('pycon_*.json', 'r')
	video = json.loads(file.read())

	for i, v in video.items():
	print("Installing {} ... ".format(v))
	url = "youtube-dl -ciw --no-mtime -f 18 \"" + str(i)+ "\""
	os.system(url)

	var eventQueue = [];
	var svg;
	var element;
	var drawingArea;
	var width;
	var height;
	var volume = 0.6;
	var ULTIMATE_DREAM_KILLER = false; // https://github.com/debugger22/github-audio/pull/19
	var orgRepoFilterNames = [];

	import sys
	from socket import socket, AF_INET, SOCK_DGRAM

	SERVER_IP = '127.0.0.1'
	PORT_NUMBER = 5000
	SIZE = 1024

	print("Test client sending packets to IP {0}, via port {1}\n".format(SERVER_IP, PORT_NUMBER))

	mySocket = socket(AF_INET, SOCK_DGRAM)

	1. compile the above code using nasm using the command :
	nasm -f bin boot.asm -o boot.img
	2. make a bootable usb of the image file created above.
