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.

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

Install ImageMagick for image conversion:

brew install imagemagick

Install tesseract for OCR:

brew install tesseract --all-languages

Or install without --all-languages and install them manually as needed.

	* TypeScript challenge for anyone to flex their TS dev skills
	*
	* Write a function wrapper that accepts any arbitrary function with arbitrary arguments.
	* This wrapper should output a new function that is a modified version of the original one.
	* This new function should have an extra argument which is last in the list of arguments. This argument is boolean and optional, named "verbose".
	* This new function works exactly like the original one, with the exception that it should output "verobse is on!" when
	* "verbose" argument is set to true.
