dwilkins / database.yml

Created August 13, 2013 22:26

When deploying to Openshift this is what the database.yml should look like

	# MySQL. Versions 4.1 and 5.0 are recommended.
	#
	# Install the MYSQL driver
	# gem install mysql2
	#
	# Ensure the MySQL gem is defined in your Gemfile
	# gem 'mysql2'
	#
	# And be sure to use new-style password hashing:

gstreamer to browser (uses vlc plugin though)

	Ok. Here is the sending side.
	This is specialized for our strange needs, it may not right right for
	others.
	I don't have access to receiving side. Maintained by somebody else, and
	part of a complicated web app.
	But you can invoke VLC directly to catch this video. Just point it at the
	URL.
	Be warned that most routers do not properly handle multicast data.

	#!/bin/bash

dwilkins / debugi915.sh

Created September 6, 2013 13:55

Script to detect if the Intel i915 graphics card is sick or not. Watch the line about "RC6 residency since boot: NNNNN". If that number doesn't change, then your graphics card is about to go into thermal meltdown
