In this article, we will review the process of using JavaScript, from an MVC-based perspective, to manipulate the DOM. More specifically, we’ll engineer our JavaScript objects, their properties and methods, and their instantiations parallel to the intended behavior of our Views (what the user sees).

Officially released by Alex Sexton and Ralph Holzmann in late February of 2011, the yepnope.js resource loader features asynchronous, conditional loading and preloading of both JavaScript and CSS resources. This makes managing dependant, conditional code a breeze.

Your latest PHP/MySQL website is finally online. And it’s awesome. But it’s not as fast as you want it to be, because of the many SQL queries running every time a page is generated. And above that, you have the feeling it will not scale well under heavy loads. And you are most likely right.
In this tutorial, we will see how you can greatly improve your website’s responsiveness, and help it scale to handle many simultaneous visitors, by implementing a cache layer between your code and your database. The good news is it is fairly easy, and can be done in a few minutes!

This likely isn’t the first tutorial on testing that you’ve ever seen. But perhaps you’ve had your doubts about testing, and never took the time to read them. After all, it can seem like extra work for no reason.
This tutorial (with screencasts) intends to change your views. We’re going to start at the very beginning: what is testing and why should you do it? Then, we’ll talk briefly about writing testable code, before actually, you know, doing some testing! Let’s get to it.

Sooner or later, all developers are required to interact with an API. The most difficult part is always related to reliably testing the code we write, and, as we want to make sure that everything works properly, we continuosly run code that queries the API itself. This process is slow and inefficient, as we can experience network issues and data inconsistencies (the API results may change). Let’s review how we can avoid all of this effort with Ruby.

Many PHP programmers learned how to access databases by using either the MySQL or MySQLi extensions. As of PHP 5.1, there’s a better way. PHP Data Objects (PDO) provide methods for prepared statements and working with objects that will make you far more productive!

You know it; I know it. We should be testing our code more than we do. Part of the reason we don’t, I think, is that we don’t know exactly how. Well, I’m getting rid of that excuse today: I’m teaching you to test your PHP with the EnhancePHP framework.

Whether we like it or not, more and more developers are being introduced to the world of JavaScript through jQuery first. In many ways, these newcomers are the lucky ones. They have access to a plethora of new JavaScript APIs, which make the process of DOM traversal (something that many folks depend on jQuery for) considerably easier. Unfortunately, they don’t know about these APIs!
In this article, we’ll take a variety of common jQuery tasks, and convert them to both modern and legacy JavaScript.

If you prefer the written word, we have a fantastic session on working with Dojo Toolkit, created by Andrew Burgess.
