OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Requirements

USB Overdrive
A non-Apple keyboard with media keys (or keys you want to make "media" keys). For reference, I'm using a Microsoft Sidewinder X4

Set Up

Plug in your keyboard and install USB Overdrive.
Open USB Overdrive. Click into the Settings tab.
Click the dropdown and select "Any Keyboard, Any Application"

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

	"""strip outputs from an IPython Notebook

	Opens a notebook, strips its output, and writes the outputless version to the original file.

	Useful mainly as a git filter or pre-commit hook for users who don't want to track output in VCS.

	This does mostly the same thing as the `Clear All Output` command in the notebook UI.
