CSS selector efficiency just isn't that important to me.
That's not to say that efficiency generally isn't... it is. And I take great pride in my ability to determine the most efficient route from my home to work and the most efficient use of my time while preparing meals. However, my computer has eight gigabytes of random access memory and a quad core 2.7 gigahertz processor... As such, the load time of web pages I view is rarely affected by the speed of CSS...
As some of my more dedicated followers might know, in March I left StrongLoop (now part of IBM) after only 14 months with the company. My primary role there was as a developer evangelist which basically means I got to go around to conferences and usergroups speaking about Node.js (read more about that in an earlier post).

It has been quite the roller coaster, including everything you would expect from a startup: expanded responsibilities, fast pace, and even a successful exit.

We may refer to some nomenclature and syntax from part one, so be...
Object oriented programming (OOP) is a concept eminently familiar to those of us that have coded in Java, C++, .NET, and other languages. So why the focus on OOP? One of our primary tasks as application developers is to model the real world through code. Consider the often used example of the "Employee" and "Manager" users in a system, object oriented programming allows us to represent these two real world entities by collections of code having data and actions...
