Using strace and lsof to debug blocked processes

You can use strace on a specific pid to figure out what a specific process is doing, e.g.:

strace -fp <pid>

You might see something like:

select(9, [3 5 8], [], [], {0, 999999}) = 0 (Timeout)

	* jasmine.requirejs() returns a function that will load the file(s) required
	* and will wait until it's done before proceeding with running specs.
	* The function returned is intended to be passed to beforeEach() so the file(s)
	* is(are) loaded before running each spec.
	*
	* Syntax:
	*
	* jasmine.requirejs(options, files)
	* or

	MedicationView = Backbone.View.extend({
	events: {
	"click #edit": "editMedication"
	},

	editMedication: function(){
	var editView = new AddEditView({model: this.model});
	editView.render();
	}
	});

	This is an HTML version of a great [VIM movements cheatsheet][] designed by Ted Naleid.

	I made this because I wanted more control over the way the text was displayed, and I'd rather tweak CSS than mess with Omnigraffle. If you just want Ted's graphic overlaid on your desktop, you should download the [transparent version] of the VIM movements cheatsheet.

	I use it with [NerdTool][]. Sadly, NerdTool can't overlay transparent HTML. So I supply a background-image URL. You'll want to change that to something on your local filesystem. Here is a [screenshot][] of the results. The background image is taken from the always great [Bibliodyssey][], resized to the size of my screen.
