Do more in CSS with LESS
Learn how to use LESS to write readable and maintainable Cascading Style Sheets (CSS) for modern websites. CSS makes the terrible old days of layout tricks with tables and invisible images a dim memory. But CSS is still unfriendly, and several initiatives tried to tame it for developers. One of the best is LESS, which extends CSS with dynamic behavior such as variables, mixins, operations, and functions. LESS is a CSS-like language that compiles seamlessly into CSS either on the client side or through server-side preprocessing.

jQuery Mobile and JSON
jQuery powers many of the sites on the Internet today, providing dynamic user experience in the browser and helping to make traditional desktop applications increasingly rare. Now that browsers found on the major mobile platforms have caught up to desktop browser functionality, the jQuery team has introduced jQuery Mobile, or JQM. The mission of JQM is to bring a universal experience to all major mobile browsers, enabling rich content across the Internet, regardless of the viewing device. This tutorial examines fundamental design concepts around jQuery Mobile in the context of a sales force automation-oriented application. You create an intuitive and visually appealing mobile web application that interacts with an Internet-hosted website to store and manage sales opportunities.

Developing a Web 2.0 application using the InfoSphere Business Glossary REST API
IBM InfoSphere(TM) Business Glossary enables users to create, manage, and share an enterprise vocabulary and classification system. In version 8.1.1, the Business Glossary team introduced a REST API that makes glossary content easier to consume by enabling the development of custom applications based on particular needs. This article provides step-by-step instructions on how to develop a portable, dynamic read-write widget that uses the IBM InfoSphere Business Glossary REST API in conjunction with various Web 2.0 technologies. The widget enables users to find terms, examine the term's details, and make basic edits. Our goal is for InfoSphere Business Glossary customers to use the knowledge gained through building this sample widget as inspiration for using the REST API to create their own custom applications. This article is intended for software engineers who are familiar with Web 2.0 technologies and product designers who can apply the tools provided here to real world situations.

Simulate XQuery and XInclude functionality with PHP
Many browsers can handle XML in general, but are currently weak in their support of XQuery and XInclude. You need to work around this issue when you build web applications that combine and process XML-structured data from multiple sources. Using PHP is one solution. This article first shows how your web pages can deliver data extracts from XML using XQuery and XInclude explicitly, and then how to do the equivalent work with PHP, all within the context of a cooperative effort among garden centers.

Thinking XML: The XML flavor of HTML5
For a while, there has been a struggle for the future of markup on the web, a struggle between the W3C's XHTML 2 and HTML5, developed by the major browser vendors under a separate organizational umbrella. First, the W3C took over HTML5, and now it recently announced the sunset of the XHTML 2 effort. This makes a significant difference to the future of XML on the web, and furthermore, because of HTML5's momentum, it is now a technology that every XML developer already has to deal with. But fans of XML need not despair: HTML5 supports a proper XML serialization. Learn about the XML form of HTML5 including some key differences from older XHTML conventions and learn how to practically apply this vocabulary in modern web browsers.

Creating mobile Web applications with HTML 5, Part 4: Using Web Workers to speed up your mobile Web applications
Web applications have traditionally been stuck in a single-threaded world. This really limited developers in what they could do in their code, since anything too complicated risks freezing up the UI of the application. Web Workers have changed all of that by bringing multi-threading to Web applications. This is particularly useful for mobile Web applications where most of the application logic is client-side. In this article, you will learn how to work with Web Workers and discover which tasks are most appropriate for them. You will see how you can use with other HTML 5 technologies to increase the efficiency of using those technologies.

Innovative uses for WebSphere sMash, Part 1: Building a flexible, practical dashboard framework
When new technologies emerge -- programming languages and models in particular -- there typically follows a period where many useful "how to" articles appear to help developers get themselves started. As time passes, the guidance works its way deeper into the more advanced concepts, but it is not often that the implementation details behind an actual application of the technology is revealed. "Hello World" examples are fine for basic lessons, but as you reach the point of wanting to build something yourself, there is nothing like a real example to help provide the inspiration for that next killer application project. This article series presents three actual examples where IBM WebSphere sMash was selected and used to perform innovative and valuable tasks. These examples are all related to the operations of IBM's Green Innovation Data Center (GIDC) in Southbury, CT, USA, which has been set up both as a client briefing center and a living lab, where some of IBM's latest energy efficient hardware, software, and operational practices are being tested and developed. In Part 1, you'll see how WebSphere sMash was used to build a flexible framework for constructing data center dashboards.

Extending widgets in the WebSphere Application Server Feature Pack for Communications Enabled Applications
One of the ways that the IBM WebSphere Application Server V7.0 Feature Pack for Communications Enabled Applications (CEA) simplifies embedding communications capabilities into Web applications is through a ready-to-use set of Dojo widgets. These widgets enable click-to-call functionality, cobrowsing sessions, two-way form capabilities, and more. These widgets and the functions they provide can be leveraged by simply including the appropriate HTML element on a user's Web page. Beyond the functions they deliver right out of the box, you can extend these widgets to provide a customized, enhanced communications experience in your Web applications using your own HTML, Dojo, and JavaScript skills. To see how, follow this tutorial and extend the Collaboration Dialog and Cobrowse widgets to deliver instant messaging capability in a Web cobrowsing session.

Rich Internet applications using ZK
ZK, an open source Asynchronous JavaScript + XML (Ajax) framework written in Java code, lets you write a Web 2.0-enabled, rich Internet application without writing a single line of JavaScript code. Typical Ajax frameworks like Dojo have JavaScript libraries that expose certain API's for making "Ajaxified" calls. ZK, on the other hand, uses a meta-definition based on XML to define the user interface. Translation to HTML code then occurs when this page is requested by the client. This article introduces you to ZK and gives you a real-world example of its use running on Apache Tomcat and connecting to a MySQL database.

Explore multithreaded programming in XUL
As you create cross-platform desktop applications using XUL, you also can enhance your skills with JavaScript, CSS, and even HTML. XUL's cross-platform capabilities are not a collection of least common denominator features. Instead, XUL gives you the kind of power that you might expect from a desktop application toolkit, including access to native threads. You can even access native threads directly from JavaScript, writing code that executes in parallel. In this article, you will examine the multithreading capabilities of XUL, and create an application that uses multiple threads to retrieve data. You will take a classic IO-bound application, one that accesses multiple remote data sources over the Internet, and speed it up through multiple threads in XUL. The application will allow users to view and compare anonymous results of three popular search engines: Google, Yahoo, and Bing from Microsoft(R).
