Managing Secret Data in Open source Applications

If you're working on an open source project, committing API keys or secrets to your repo is a big no-no. You wouldn't want anyone else making request with your keys, right?

So instead of putting those keys in app/config/initializers set then as environment variables in your shell. Here's an example for a Facebook API key:

export FB_API_KEY=3629346238763284623874623

Design Process

Define the problem.
Wireframe.
Prototype.
Test, gather feedback, refine.

Define the problem

Talk to people (users, clients, customers, businesspeople).

Web App Performance

Back End

N+1

  @users = User.all.includes(:profile) # SELECT * from users

Excessive joins/subselects or exta queries

CHEAT SHEETS

$ command line ruby cheat sheets

INSTALL

$ gem install rspec

Definitions

General Testing

TDD Test Driven Development. Write examples before implementation.
BDD Behaviour-Driven Development is about implementing an application by describing its behavior from the perspective of its stakeholders. (The Rspec Book)
RSpec (mention alternatives, write a simple hand sewn test)

Tips for a #WINNING Github Profile

The basics

As a new developer some potential employers are going to review your Github profile as part of the interview process. This doc covers some tips that should help you make a good impression. What this doc won't do is polish a turd.

README

Think of your experiences reviewing a Gem or other JS library on Github. Where do you look first? The README of course. What makes for a frustrating repo? One that doesn't:

include a README.
include install instructions (if applicable)

#Git workflow

To understand git on a conceptual level, visit this git visual demo, the most epic git tutorial on the web.

We are chosing to work with a branching workflow. Every pair works in their own branch, and when we have our branch working to our satisfaction, we merge it into the master branch.

###Set up github repository

Set up git repository and add everyone as collaborators.

	// TicTacToe.cpp
	// for CS 141 lab 4
	// Password: Brown
	//
	#include <iostream>
	using namespace std;


	//----------------------------------------------------------------------------------
	// Display the board.

	require 'benchmark'

	class Sudoku

	def initialize(board_string)
	@board = create_board(board_string.split(//).map {\|str\| str.to_i})
	@potentials = (0..9).to_a
	end

	def create_board(num_array)
