Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

The game we're building is a simple side-scrolling racing game. The player's car is static on the screen, only the background is moving. The enemies are planes whom the player must dodge using the up and down arrow keys. If the player hits a plane, he dies. One point is given each time a plane goes off screen without touching the player.

Sprites

Our game is composed of sprites. Each sprite has a position (x, y), velocity (speed) and one image, or more if animated.

Images are loaded from the DOM using their CSS selector (imagesSelector). We use ID selectors (#name) for single images and class selectors (.name) for animated sprites composed of several images.

See the images used in the game.

Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

1. Get an OAuth Token from GitHub

First you will need to get an OAuth Token from GitHub using your own username and "note"

# inspired by https://mriet.wordpress.com/2012/07/01/merge-bubbles-are-bad/
# and http://snipplr.com/view/26715/

# 1. first rebase all your local commits into one commit, e.g. for the last 3 commits into one you can use

git rebase -i HEAD~3

# and 'pick' the first, 'squash' the other commits

# 2. check the commit's sha id and save it somewhere
