Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

Sample service script for debianoids

Look at LSB init scripts for more information.

Usage

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)

Download and install p4merge

Download the perforce visual tool suite from here: http://www.perforce.com/perforce/downloads/index.html
Copy only the p4merge.app file into your /Applications/ directory

Setup p4merge as a visual mergetool

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout. This is also called reflow or layout thrashing, and is common performance bottleneck.

Element

Box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
elem.getClientRects(), elem.getBoundingClientRect()

	path.lineWidth = 4
	NSColor.greenColor().setFill()
	NSColor.blackColor().setStroke()
	path.fill()

	/* Quick implementation of Exponential and Geometric random number generators

	For example you can use it to simulate when an event is going to happen next, given its average rate:

	Buses arrive every 30 minutes on average, so that's an average rate of 2 per hour.
	I arrive at the bus station, I can use this to generate the next bus ETA:

	randomExponential(2); // => 0.3213031016466269 hours, i.e. 19 minutes
