Have you ever wondered if your skills are in demand? With so many different possibilities available for web development, it is tough to know if you should keep mastering a specific technology or start learning a new one. After reading an article about how PHP programming jobs are in high demand, I asked myself the follow-up question: what other skills do I have that are in high demand, and which skills do I have that are not?

The article linked to a great resource from oDesk that lists the current (monthly) trends for many of the development and design skills used for web development. There are 84 different trends with a wealth of useful information about the skill's demand including graphs, stats, and recent job postings. Although these stats are pulled from information specifically on oDesk, it represents demand from all around the world. I have listed links to some of the most in-demand skills right now.

• CSS
• Drupal
• FreeBSD
• Flash
• PHP
• Photoshop
• MySQL
• XML
• JavaScript
• Ajax

As a side note, this site is a fantastic example of how great the Google Chart API is.

If you have ever wanted/needed to be able to print just part of a page before, now you can. jPrintArea will allow you to print only the contents of a specific element (Ex: div). There aren't a lot of extra bells & whistles that go along with this jQuery plugin, but it works great. It does exactly what is need with only a few lines of code so there is little extra overhead added to your page load time.

There is a sample usage, a demo, and source code (download and view) available from the website. I have included a sample demo below as well.

Sams Teach Yourself books are great resources in a large array of topics. They have released Sams Teach Yourself Ajax, JavaScript, and PHP All in One in paperback version on July 12, 2008. This book is great for webmasters because it includes three of the most popular technologies used on the web.

Like all the rest of the "Sams Teach Yourself" line of books, this one is easy to follow, easy to understand, and takes you from a beginner to an intermediate and beyond. There are a number of visual aids including screenshots and diagrams to help you understand what you have read. Another great help is the amount of code examples used throughout the book; there are examples for most of the topics covered.

The book starts with a general overview at the beginning and works towards a more detailed explanation at the end. In chapter one, you will learn the basics of the web, HTML, CSS, and Ajax. By the end of chapter nine, you will understand JavaScript, using it to manipulate the DOM and add usability to your site. By chapter thirteen you will be using Ajax and by the end of chapter eighteen, you will be using Object Oriented PHP to make your site dynamic. Once you have taken all of that in, you can learn about XML responses, web services (REST and SOAP), and gain a basic understanding about a few popular Ajax tools and libraries that are available.

An added feature with this book is beyond the pages of helpful information. There is a CD provided with the book that includes all of the software needed to get a basic web server up and running. It includes XAMPP, jEdit, Prototype, Scriptaculous, Rico, XOAD, searchable PDF tutorials, and source code for the examples in the book. Most of these are freely available for download on the web, but it is nice to have them all in one place, especially for a beginner that doesn't know what to look for.

This book is well worth your time to read, especially if you are a beginner looking to get not only introduced to these web technologies, but also get started using them. You can pick up your copy at Amazon.com and get started building dynamic websites using Ajax, JavaScript, and PHP.

PrototypeXtensions adds additional components to Prototype.js and Script.aculo.us, two of the most popular and widely used JavaScript frameworks/libraries available. While these are extremely useful tools for creating visual effects, UI improvements, and Ajax methods, the creators of PrototypeXtensions realized a need for additional components. The library is currently at version 0.1.2 and is released under MIT License. There are three main categories of additions, or extensions, that are added by this library with specific features within each category. I have listed a basic feature overview below.

Features

There are detailed explanations and examples for each feature available so be sure to check out the website for more detailed features and information. You can download the current release in the original uncompressed form or download the smalled Minified and Gzipped version.

LightWindow is a JavaScript framework based on Prototype and Scriptaculous. If you aren't familiar with these two amazing resources, it is definitely worth your time to become familiar with them. They are two of the most useful resources available for Web 2.0 developing. LightWindow takes the combination of those two frameworks and adds some really cool things to it. The reason I decided to use LightWindow the first time was to embed media easily into my website. I needed to show some videos and wanted a better way to do it than just embedding it into the page (I hadn't designed a good spot on the page for a video). LightWindow was not only able to meet the needs of the video I wanted to show, it ended up meeting needs I didn't even have at the time. Here is a listing of all the great features that LightWindow boasts.

• Media - You are able to load various types of media, including YouTube videos, Flash videos (SWF), QuickTime videos, and Flash Paper PDFs. There is support for all and every media type; that's pretty hard to beat.
• External Websites - You are able to load an external source as well as an internal source. This creates a type of pop-up window, but it is much cooler!
• Images - You are able to load images from internal or external sources. You can also load image galleries for viewing multiple images in a nicely laid-out design.
• Forms - You are able to load and use forms within the LightWindow. Full functionality is provided with easy to follow instructions for setup.
• Pages - You are able to load various page types, including fluid, fixed, and specific dimensions.
• Inline Content - You are also able to load basic content from a container. (The author calls this one a "gimme.")
• Themes - You can create your own theme for colors, styles, and animations. This is not easy to accomplish however. The author has not released any tutorials or help files for this, but says that it is possible.
• On the Fly - You can create and instantiate a window on the fly without needing to create it first when the page loads.
• Parameters - You can use various parameters to customize your window. Some examples are title, author, and caption.

This is one of the easiest frameworks to learn and to use. At the cost of free, I don't think there is a better choice out there that boasts all the features, ease of use, and quality of LightWindow.

You can visit the LightWindow website and download your copy of the framework (v2.0). If you like what Kevin has done, be sure to donate and show your appreciation!
