I’ve been the owner of an Android phone for about 5 months now. The thought of creating an application for the Android platform has appealed to me ever since. That’s why I recently started with Android development as a learning project for the next couple of weeks. In this post I will start sharing my experience with developing Android applications.
If you’re working as a web developer with Hippo CMS, I guess you have written quite a few HST components. I presume that by now you will have a basic understanding of what HST components can and can’t do. I’ve had the situation myself where I wanted to share some information between components on a single page. I first thought I could simply achieve this by adding an attribute to the request, but that didn’t work. To show you what you can do, let’s first start of with a bit of background information about what’s actually going on inside the HST, when an incoming request is being processed.
A couple of weeks ago I made myself a promise that I would look into a new technology every month and write something about it here. I’ve been looking around for technologies unknown to me and perhaps to some of you, so I will start out with a RIA framework called Vaadin.
Quality is an important aspect of every software development project. Writing unit tests is just one part of keeping an eye on quality. In this post I will try to explain how you can unit test your Hippo Site Toolkit (HST2) components, so you can be sure that the component still behaves as expected even after multiple maintenance cycles.
Most developers working with Java hardly have to think about the memory footprint of their application that they wrote. The garbage collector inside the JVM will remove most waste, but what happens when not all waste can be removed or something is wrong inside the application? This may result in an exception that probably a lot of developers and system administrators have seen before: java.lang.OutOfMemoryError (OOME). There are several causes for such an exception, but the most obvious is that there is memory leak somewhere in the application.
