  The seven rules of Unobtrusive JavaScript

I've found the following rules over the years developing, teaching and implementing JavaScript in an unobtrusive manner. They have specifically been the outline of a workshop on unobtrusive JavaScript for the Paris Web conference 2007 in Paris, France. I hope that they help you understand a bit why it is a good idea to plan and execute your JavaScript in this way. It has helped me deliver products faster, with much higher quality and a lot easier maintenance. 1. Do no...

It can be assigned to variables of pointer, slice, map, channel, function, and interface types.

  Learning Ruby and Ruby vs Lisp

The company I work for has a lot of legacy Ruby code, and as Ruby has become kind of a mainstream language, I decided to get a book about it and learn how it works. As my learning resource, I chose The Ruby Programming language by David Flanagan and Yukihiro Matsumoto as that receives great customer reviews, covers Ruby 1.8.7 and 1.9 and is authoritative because the language creator is one of the authors. The book makes a good read in general. There are plen...

  JavaScript-style object literals in PHP

The object literal notation in JavaScript looks like: var fido = {name: "Fido", barks: true}; or var fido = {}; fido.name = "Fido"; fido.barks = true; From assoc arrays to objects In PHP you would call that an associative array. $fido = array( 'name' => "Fido", 'barks' => true ); And you can easily make it an object too: $fido = (object)$fido; echo gettype($fido); // "object" Or if you want to start with a blank object and add stuff to it: $fido = (object)array(); or $fido...

Young scientists at a Chinese genomics institute are foregoing conventional postgraduate training for the chance to be part of major scientific initiatives. Is this the way of the future?The approach to extended postgraduate training varies from country to country.

  CSS Animation vs. JavaScript: Which One Is Better?

You know that there are two ways of creating animations on the web: with CSS and JavaScript. And, their selection completely depends on the dependencies of the project. But many web developers hold a wrong perception that CSS is the only way of creating the animations. In fact, CSS has established as the most pampered system of the web development industry and most of the developers recommend it because it is mobile-friendly and powerful system. No doubt CSS is good, but JavaScript is the best....

  How big are PHP arrays (and values) really? (Hint: BIG!)

Upfront I want to thank Johannes and Tyrael for their help in finding some of the more hidden memory usage. In this post I want to investigate the memory usage of PHP arrays (and values in general) using the following script as an example, which creates 100000 unique integer array elements and measures the resulting memory usage: <?php $startMemory = memory_get_usage(); $array = range(1, 100000); echo memory_get_usage() - $startMemory, ' bytes'; How much would you expect it to ...

What should a ‘cache’ be? It means a lot of things, but to my mind the default programming type should be: “keep around expensive-to-generate bits of read-only data in case we need them again, or until the computer really needs that RAM for something else” I was writing a custom video editing program in Python (interesting choice of language for that problem) and I wanted to cache decoded frames; but I just wasn’t happy with the memory management of explici...

  Creating a PHP 5 Extension with Visual C++ 2005

This article describes the steps to create a custom PHP extension DLL for the Windows platform. The Zend API documentation that comes with PHP 5 on Windows (see php_manual_en.chm) does a good job explaining how to write extension methods, parse method parameters, and return values. But there is not currently a good step-by-step tutorial on how to get your first extension project up and running on Windows. The aim of this article is to fill that gap. Prerequisites Visual Studio 2005 You can...
