Debounce a function when you want it to execute only once after a defined interval of time. If the event occurs multiple times within the interval, the interval is reset each time.
Example A user is typing into an input field and you want to execute a function, such as a call to the server, only when the user stops typing for a certain interval, such as 500ms.
The script in this gist will help you buid the Google Protobuf library for use with Mac OS X and iOS. Other methods (such as homebrew or direct compilation) have issues that prevent their use. The libraries built by this script are universal and support all iOS device architectures including the simluator.
The easiest way to use this script is to simply clone the gist onto your

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