System Design Cheatsheet

Step One: Framing The Problem a.k.a get the MVP

• Identify the use cases that are in scope
• Determine constraints based on scoped use cases

use case : the things your system needs to be do.

constraints : the things your system will have to consider to be able to do stuff

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.

/**
 * Base contract that all upgradeable contracts should use.
 * 
 * Contracts implementing this interface are all called using delegatecall from
 * a dispatcher. As a result, the _sizes and _dest variables are shared with the
 * dispatcher contract, which allows the called contract to update these at will.
 * 
 * _sizes is a map of function signatures to return value sizes. Due to EVM
 * limitations, these need to be populated by the target contract, so the
 * dispatcher knows how many bytes of data to return from called functions.

limitLoop.js - limit the frame-rate when using requestAnimation frame
Released under an MIT license.

When to use it?
----------------
A consistent frame-rate can be better than a janky experience only 
occasionally hitting 60fps. Use this trick to target a specific frame-
rate (e.g 30fps, 48fps) until browsers better tackle this problem
