The full process is automated and the machine does the translation. However, machine translation is not always good and can sometimes be misleading. To avoid your content getting lost in translation, or in the absence of a translation service for a specific language, like Bengali, you may like to manually translate the site's content. In this article by Suhreed Sarkar, author of Joomla! 1.5 Top Extensions Cookbook, you will learn how to translate your site's content manually into your desired language using the Joom!Fish extension. It allows you to translate the articles, modules, banners, menus, sections, categories, and so on into your desired language. It also shows a language selection module for visitors to choose a language from the site's frontend. Many other components and modules can be translated by installing their respective content elements. http://www.packtpub.com/article/manually-translating-joomla-content-into-your-desired-language Thu, 28 Oct 2010 15:10:56 +0500 This article focuses on using multiple languages on a Joomla!-based site.

In this article by Matt Perdeck, author of ASP.NET Site Performance Secret, we will see how to load JavaScript code on demand, and techniques to load JavaScript without blocking page rendering. http://www.packtpub.com/article/aspnet-site-performance-reducing-page-load-time Thu, 28 Oct 2010 15:03:01 +0500 One approach to improving page performance is to shift functionality from the server to the browser. Instead of calculating a result or validating a form in C# on the server, you use JavaScript code on the browser. A drawback of this approach is that it involves physically moving code from the server to the browser. Because JavaScript is not compiled, it can be quite bulky. This can affect page load times, especially if you use large JavaScript libraries. You're effectively trading off increased page load times against faster response times after the page has loaded. In this article by Matt Perdeck, author of ASP.NET Site Performance Secret, you'll see how to reduce the impact on page load times by the need to load JavaScript files. It shows: How JavaScript files can block rendering of the page while they are being loaded and executed How to load JavaScript in parallel with other resources How to load JavaScript more quickly http://www.packtpub.com/article/aspnet-site-performance-improving-javascript-loading Thu, 28 Oct 2010 15:02:14 +0500 PostgreSQL is a powerful, open source object-relational database system, which runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows.

This article by Gregory Smith, author of the book PostgreSQL 9.0 High Performance, discusses how the main components in server hardware, including processors, memory, and disks, need to be carefully selected for reliable database storage and a balanced budget. http://www.packtpub.com/article/postgresql-9-balancing-hardware-spending Wed, 27 Oct 2010 11:03:51 +0500 We might want to start off by saying tooltips are very popular in today's web design. This is probably due to the value that the tooltips add to the overall look of a website and the sensible addition to a nice user experience that they will certainly contribute. Also, as we have seen for many other plugins, which are not that difficult to create—provided we know exactly what to do and how to do it—there shouldn't be much of an issue with developing the tooltip plugin. It may actually take some time to understand how to position elements based on the mouse cursor position itself and how to move deftly with an increasing number of functions doing different things. However, we're now on the path to becoming experts, and fearless too! The topics we're going to discuss in this article by Giulio Bai, author of jQuery Plugin Development Beginner's Guide, include: Tooltip plugins in general Positioning the tooltip Merging pieces together Custom jQuery selectors http://www.packtpub.com/article/jquery-user-interface-plugins-tooltip Wed, 27 Oct 2010 10:59:05 +0500 Packt has come up with a special offer on one of its titles - Java EE 5 Development with NetBeans 6 http://www.packtpub.com/exclusive-discount-java-ee-5-development-with-netbeans-6-rss-27-oct Wed, 27 Oct 2010 10:06:27 +0500 Packt has come up with a special offer on one of its titles - IT Inventory and Resource Management with OCS Inventory NG 1.02 http://www.packtpub.com/exclusive-discount-ocs-inventory-ng-1-02-it-inventory-and-resource-management-rss-27-oct Wed, 27 Oct 2010 09:58:53 +0500 Statistical Analysis with R debuts this October in our Open Source category.   http://www.packtpub.com/article-awards-page-content-statistical-analysis-with-r-beginners-guide Wed, 27 Oct 2010 09:18:43 +0500 In the previous article, Securing a BPEL process, we saw the principles of securing BPEL processes.
