Using Groovy Closures Instead of Template Method
by Nirav Assar |
December 2010 | Java Open Source
A good software developer always keeps the DRY principle in mind. Whenever code is duplicated, maintainability problems are introduced and the code base becomes difficult to understand. Java developers often rely on the template method pattern to reuse code. Groovy's closure programming concept is an alternative way to solve similar problems. Closures provide a concise way to pass around code without the ceremony involved with design patterns. This article by Nirav Assar will demonstrate how closures are used to embrace the DRY principle.

Neil Mackenzie | August 2011 | Cookbooks Enterprise Articles Microsoft
A Windows Azure hosted service may comprise multiple instances of multiple roles. These instances all run in a remote Windows Azure data center—typically 24*7. The ability to monitor these instances non-intrusively is essential both in detecting failure and in capacity planning.
However, there are times, especially early in the development process, when non-intrusive diagnostics monitoring is not sufficient. In this article by Neil Mackenzie, author of Microsoft Windows Azure Development Cookbook, we will see the benefits of intrusive monitoring of a Windows Azure role instance using IntelliTrace.

Karthik Kumar | February 2011 | Content Management Drupal Open Source
Until a few years ago, mentioning the word JavaScript to a themer would usually result in groans about inconsistencies in browser support, lack of standards, difficulty in debugging, and a myriad of other complaints. Thankfully, however, things have changed considerably since then. Browsers have evolved and standards have improved. JavaScript is now a potent weapon in any themer's armory and this is especially true with the introduction of cross-browser libraries and frameworks which address most of the aforementioned issues with it.
In this article by Karthik Kumar, author of the book Drupal 6 Theming Cookbook, we will be covering the following recipes:
- Including JavaScript files from a theme
- Including a JavaScript file only for certain pages
- Giving the username textfield keyboard focus

Using JavaScript Effects with Joomla!
by
| November 2008 | Joomla! MySQL Content Management Open Source PHP
Although Joomla! has all of the basic content management tools you need to build a website, it is also designed to run custom-built extensions written in PHP. This article steps through working examples of PHP code written to work seamlessly in Joomla!. Modern websites use JavaScript-driven effects to aid navigation, reduce on-screen clutter, and provide interactive features that are not possible with static HTML.
Joomla! has several built-in elements that you can use without writing a single line of JavaScript. The MooTools framework powers many elements seen throughout the Joomla! backend UI; these can be reused in both the frontend and the backend of your Joomla! component. In this article by Joseph L. LeBlanc, we will learn to use JavaScript effects through these topics:
- Customizing Google Maps

Using Location in your iOS Apps – Core Location
by
Zeeshan Chawdhary | April 2012 | Architecture & Analysis Beginner's Guides
The Core Location framework in the iOS SDK is an asynchronous API that uses delegation to report location information from the iOS device. Along with location information, Core Location also reports the Heading information (Heading here implies the direction in which a device is pointed), as well as allowing you to define geographic regions and monitor when you cross those regional boundaries.

by
Zeeshan Chawdhary | July 2012 | Enterprise Articles
Maps provide a great visual experience for location-based services. Maps are now a default feature on most smartphones as they provide a good graphical overview of information (usually geotagged data) around the user's location.
With custom pin markers and directions, maps also help users navigate to their destination easily. Most importantly maps give the user a feeling that "This place is around the next block, north from where I am standing," so decision-making happens quickly for the user.
In this article by Zeeshan Chawdhary, author of Windows Phone 7.5: Building Location-aware Applications we shall cover the following topics:
- Understanding map geometry
- Overview of Windows Bing Maps Silverlight Control
- Using maps in your Windows Phone application – Hello Maps
- Using pushpins with maps
- Custom map pushpins
- Handling pushpin events
- Working with Bing Maps geocoding and reverse geocoding services
- Overview of Launchers and Choosers
- Using directions with Bing Maps directions task
- Performing local searches with BingMapsTask

Using Moodle to integrate a Foreign Language Course in Secondary School
by Mariella Proietta |
March 2010 | Moodle
The article by Mariella Proietta, aims to plan teaching and learning English as a foreign language. It discusses how to go about using the material available in the secondary school language textbook, to test Moodle as an E-learning platform in blended mode, and support rather than substitute the conventional class activities. Moodle can be used to integrate a school course for young people, with online activities that help them to increase their foreign language proficiency and also their competence in ICT(Information and Communication Technology). Most foreign language courses in secondary schools are supported by textbooks that provide plenty of audio material like audio-cassettes, CDs and even CD ROMs, but students seem quite reluctant to use these tools at home. The idea here is to take the advantage of Moodle E-learning environment to enrich the learning process, through a more complete exploitation of the teaching resources, contents and other the aids connected with the textbook chosen.

Using Prototype Property in JavaScript
by
Stoyan Stefanov | August 2008 | AJAX Web Development
In this article by Stoyan Stefanov, you'll learn about the prototype property of the function objects. Understanding how the prototype works is an important part of learning the JavaScript language. After all, JavaScript is classified as having a prototype-based object model. There's nothing particularly difficult about the prototype, but it is a new concept and as such may sometimes take some time to sink in. It's one of these things in JavaScript (closures are another) which, once you "get" them, they seem so obvious and make perfect sense. As with the rest of the article, you're strongly encouraged to type in and play around with the examples; this makes it much easier to learn and remember the concepts.

Rihards Olups | March 2010 | Networking & Telephony Open Source
In this article by Rihards Olups, author of Zabbix 1.8 Network Monitoring, we'll explore usage of proxies that collect the data on behalf of the Zabbix server and then transmit it back to the server, which helps when remote locations can't be accessed directly because of firewall concerns. It also reduces the load on the Zabbix server.

by Eric Spiegelberg |
August 2010 | Java Open Source
Java Management Extensions (JMX) is an incredibly powerful Java technology. Introduced in 2003 as part of Java 5 and the result of multiple Java Community Process specifications (JSR-3 and JSR-160), JMX defines an architecture, API, and services for the management and monitoring of Java applications. Simply put, JMX is a standard part of Java used to interact with a running application. Once started, you probably tend to think of an application as if it were on its own island and that it's difficult to communicate with. Or perhaps you've never needed to interact with a running application or didn't realize such functionality was a possibility. JMX makes these interactions possible and can be used to receive event notifications or to invoke the functionality (such as business logic) contained within your running application. These interactions occur between a JMX client running locally and any Java Virtual Machine (JVM) running on a local or remote machine.
The topic of the article by Eric Spiegelberg, is a design for using JMX and Spring to interact with applications at runtime; the writing is one part a very light introduction to JMX, one part an introduction to the benefits of Spring JMX, and one part that presents a design for how to quickly and conveniently maximize the use of Spring JMX within your Java applications.
