System Design Cheatsheet

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

Basic Steps

Clarify and agree on the scope of the system

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?

iTerm2 Shortcuts

Tab navigation

open new tab: Cmd + t
next tab: Cmd + Shift + ]
previous tab: Cmd + Shift + [

Pane navigation

In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So ⌘ + D does not mean hold shift. ⌘ + Shift + D does of course.

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

	Below are the Big O performance of common functions of different Java Collections.


	List \| Add \| Remove \| Get \| Contains \| Next \| Data Structure
	---------------------\|------\|--------\|------\|----------\|------\|---------------
	ArrayList \| O(1) \| O(n) \| O(1) \| O(n) \| O(1) \| Array
	LinkedList \| O(1) \| O(1) \| O(n) \| O(n) \| O(1) \| Linked List
	CopyOnWriteArrayList \| O(n) \| O(n) \| O(1) \| O(n) \| O(1) \| Array

	....

	OS X Terminal Commands
	Mail: get read receipts
	defaults write com.apple.mail UserHeaders '{"Disposition-Notification-To" = "myname <my@email.com>";}'

	to stop read receipts
	defaults delete com.apple.mail UserHeaders

	mirror source to destination:
	rsync -aE --delete "/path/to/source/" "/path/to/destination/"

	1.) Algorithm Complexity: You need to know Big-O. If you struggle with
	basic big-O complexity analysis, then you are almost guaranteed not to
	get hired.

	2.) Coding: You should know at least one programming language really
	well, and it should preferably be C++ or Java. C# is OK too, since
