Raspberry Pi Breathing LED

This is a demonstration of using Ruby and the WiringPi Gem to pulse an LED connected to a GPIO pin in a manner similar to the sleep indicator on a MacBook.

A video of the effect can be found here: http://www.youtube.com/watch?v=NCUMXK7qf-c

Sublime Text Monokai Sidebar Theme

A theme for the sidebar in Sublime Text to match the workspace of the Monokai theme.

This theme only modifies the sidebar to better match the Monokai theme, without modifying any of the styling elsewhere defined by Monokai.

File location: Packages/User

For a theme that extends beyond just the sidebar, visit https://gist.github.com/umpirsky/5842174

Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.

	# Notes:
	# 1) You need an oyster card that has been registered on tfl.gov.uk
	# 2) This script requires you to enter your username and password (this about what that means before progressing, and do so at your own risk)
	# 3) This script should be run in a PRIVATE SCRAPERWIKI VAULT ONLY https://scraperwiki.com/pricing/ not a public scraper, or the world will know your password
