There are a lot of ways to go about black box testing, but the main purpose of this post is to assist new and junior testers. Here you can read about the main strategies for testing, some terminology used and methods that will help you in the beginning of your career as a tester.

These days it is very important to be informed, mobile and connected with the other parts of the world. The future of development is in the applications for mobile devices. One very useful feature of these devices is their GPS module, which provides your current location. In this post I will show you how to use the coordinates from the GPS in a Google Android application running in the background.

There are a lot of tutorials and posts explaining how to display a chart in a web application and which libraries to use. I am going to show the process from receiving the http request from the client to sending the response back from the server. I will share my real experience with JFreeChart and the servlet technology for creating and displaying dynamic charts in Java based web application.

This tutorial introduces you to the basic concepts of XML and using a Document Object Model (DOM) as a parser for the iPhone to parse XML. The intended audience is XML beginners with knowledge of Objective C.

XML (Extensible Markup Language) is a set of rules for encoding documents electronically. It is defined in the XML 1.0 Specification produced by the W3C. XML’s design goals emphasize simplicity, generality, and usability over the Internet. Although XML’s design focuses on documents, it is widely used for the representation of arbitrary data structures, for example in web services. A variety of APIs for accessing XML have been developed and used, and some have been standardized.

Thinking of developing a Facebook FBML Application? It is certainly a very exciting and inspiring task. Let me make it as fun for you as possible by pointing out a few obstacles you may come across and ways to bypass them. I personally stumbled upon each of the problems listed below in my first steps in Facebook development. Hopefully, this will help those of you who are taking your first steps into Facebook development avoid some headaches along the way. Let’s get started!

With the great significance of the large screen on iPhone / iPod Touch, the graphical user interfaces experience of iPhone applications are more important than on other mobile platforms. One possible approach to make your application more interactive and dynamic is to use the default iPhone Design Resource UIWebView with local style definition (CSS) and JavaScript.

Paging queries or paging records is an often-used approach in web applications. It displays subsets of data records as a page, allowing the user to navigate more easily through all pages. The straightforward implementation of a paging query running over large data sets in a stored procedure in MS SQL 2005 can cause increased server load when large numbers of paging queries are executed simultaneously.

Recently, we’ve been dealing with an issue related to our Tomcat Application Server and wanted to share how we solved this one. We found one that the application server was irrelevant (it could be Glassfish or another as well). The server was running the latest version, Tomcat Application Server 6.0.18, and it was crashing in irregular intervals. There was no easy solution because the server stopped making logs before crashing.

Developers who have used NetBeans 6.1 and 6.5 for web development with Visual JSF (Woodstock) might have encountered an issue with their web application when deployed on a secured server (HTTPS) and opened with Internet Explorer. The issue lies in the way IE treats links to JavaScript and CSS files loaded in the pages. Under HTTPS, the links to JavaScript have to be absolute, not relative. IE does not assume that the “relative” folder is secured.
