One of the welcome developments in GWT 1.5 was the inclusion of some decent looking CSS themes -- standard. chrome and dark. How can you use them in your GWT app? Just include one of the following lines in your apps .xml file. You can see them in action in the ShowCase application. For...
Just a quick update from the conference (which is now over). I gave my talk at AJAXWorld East 2008 and got some interesting reactions. Met a lot of cool folks, put some faces to names, got to sit on a panel with Douglas Crockford. Cool beans. More next week.
Just as with advertising measurement for AJAX, I continue to follow the technology known as Comet (open up an HTTP request from browser to server, then keep it open, pushing content down periodically) to see if it is ready for prime time. I thought I'd share my reading list from the la...
Half a year has passed since I published my article 36 GWT Tutorials. As expected, several new tutorials have come along that demonstrate deeper, more sophisticated aspects of the framework, as well as addressing specific IDEs and libraries. I myself am working on a more extensive tuto...
Performance can have different meanings, depending on your perspective. If you're the end user of an application, performance means that the application is responsive in all circumstances. If you're an application owner or product manager, performance may mean that the application is s...
How do we measure the network performance of a Web application? There are a number of tools that can help us measure and diagnose network performance issues, but the best place to start is by taking a look at the initial page, where we load most of the JavaScript, CSS, and images that ...
One way of speeding up transfer times of resources between the server and the browser is to reduce the size of the resource being transferred. Practically all modern browsers can receive and decompress compressed content via HTTP. Using one of the HTTP traffic-monitoring tools mentione...
In some cases you may not know precisely where a performance bottleneck lies. Using our technique of surrounding suspected bottlenecks with timestamps won't work in these cases. We need a way to get a broader overview of application performance. Fortunately there are a number of profil...
Most of the performance optimizations in this section should be familiar to anyone who has performance tuned pre-AJAX JavaScript. In fact, on the client side, the prescription for tuning the code of AJAX applications hasn't changed that much from tuning plain JavaScript: replace expens...
