I recently acquired a Logitech Spotlight Presentation Remote to help me during my presentations. While some conferences propose clickers to speakers, not all of them do. And it’s quite inconvenient to be bound to the laptop to advance to the next slide when presenting, as I like moving around in general. When I received the remote, I was eager to test it, and I was happy to assert it worked on Google Slides. The root issue I went to a meetup just afterwards, and I couldn’t help no
I must admit I suck at graphical design. It’s one of the reasons that put me in the way of Flex and Vaadin in the first place: out-of-the-box, you got an application that is pleasing to the eye. Using one of these technologies is not possible (nor relevant) in all contexts, and since I’ve got a strong interest in UI, I regularly have a look at other alternatives for clean looking applications. The technology I studied this week is Twitter Bootstrap. Bootstrap is a lightweight clie
Let me first say I was not at Devoxx 2010. Yet, I heard from Matt Raible's Comparing JVM Web Frameworks. Like many, as I read the final results, I was very surprised that my favorite framework was not ranked first. I passed through all stages of grief, then finally came to realize the presentation itself was much more interesting than the matrix. The problem lies not in the matrix, but in the method used to create it.
In the previous article, I set up a cluster of 2 Tomcat instances in order to achieve load-balacing. It also offered failover capability. However, when using this feature, the user session was lost when changing node. In this article, I will show you how this side-effect can be avoided. Reminder: the HTTP protocol is inherently disconnected (as opposed to FTP which is connected). In HTTP, the client sends a request to a server, it gets its response and that’s the end. The server cannot na
1. Generalities Web applications have several advantages over traditional client server applications: since business code comes from a unique server (forget clustering here), they are always up-to-date. Moreover, deployment of a new version is only a matter of minutes. They have one big drawback, though. Since HTML code is sent through the network, responsiveness is generally much less than that of traditional applications. The responsiveness of an interactive system describes how quickly
