Eclipse RCP training near you published an interesting news bulletin today. It appears Eclipse RCP classes are comming to a city near you. Have a look over here for the current time-table. I did not do a background check of the people giving the course, but hey, it only costs 1100 euros. A ridiculous low price if you ask me. What is the catch? Or is it heavily sponsored by My employer has a three day java Swing course available for 1350 euros. That’s one day less AND it costs more.

I am very curious about this. If the quality is good (how can it be for so little money) it is a bargain! Any thoughts on this will be much appreciated. Especially on how they can do this for such a small fee.

Rich Client Vs. Web: User interface

One of the most visible effects of choosing either web or desktop technology is the way the resulting application will appear. Right now there are a couple of development frameworks to take into consideration. These are in no particular order:

  • Basic web application
  • AJAX
  • Netbeans/Eclipse Rich Client
  • Swing/SWT application

(This list is Java oriented.)

All of these have advantages and disadvantages. The list above can be divided into two main categories. To no surprise these are Web and Desktop. Anyway, right now I’m working for my employer on a document which ellaborates on these differences. Also I’ve submitted a proposal to the NL-JUG’s upcomming J-Fall to do a talk about this subject for my employer. I hope they’ll agree with me that it’s an important subject to reflect on a bit.

djay for OS-X

djay Screen shot
I came accross a great little Os X app today: djay The reason for blogging about this app is simple. Just look at the screenshot. It’s so intuitive it’s almost painfull. Wanna scratch a little, grab that record and work it out with your mouse. Next I was wondering how I could change the time index. There was no button or menu item anywhere. I was just thinking to difficult. Click on the arm and drag the LP player and you are changing the time index. You get suitable feedback at the top of the screen while handling the arm, the time index shows below the time remaining index.

Anyway enough of the fun stuff. My point is, this little app just clicks. The UI looks great and it you can control the application without a hitch in a very intuitive way. While it is just a little “app” (well, it does a lot of fun stuff with the Quicktime Framework under the hood), it’s an excellent example of taking a step back before creating a UI. The point is, think before slapping together another UI. It’s very important that a UI just flows and feels right.

Rich Client vs. Web 2.0 – Deployment and maintenance

Finally you’ve finished your latest wonder. Now to boldly move on to marvellous new functionality.

Wait a second.

Before moving on to something else it would be nice of you to actually make your app available to your users.

Let’s see. This one should be a bit of a no-brainer according to most people. Usually people start blabbering about how easy it is to deploy and maintain a web application. While this is true most of the time, things do tend to get a bit more complicated with Web 2.0. Things like Javascript and browser versions come to mind. And Rich Clients are supposed to be hard to deploy.

Rich Client vs. Web 2.0

In my opinion a lot of companies are going to make decisions in the near future about using Web 2.0 or Rich Client for their next end-user applications. Both have their respective strong and weak points.

Over the next couple of weeks I intend to put up some postings about my opinion on various aspects of Web 2.0 compared to Rich Client development. Since I myself am mostly involved with Java software development I will focus on the aspects of frameworks and platforms based on the Java language.

For this intro, let’s lay down some basics by defining what Web 2.0 and Rich Client is.

I’ve found a nice definition of Web 2.0 at O’Reilly Radar:

Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an “architecture of participation,” and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.

Now on to Rich Client. There is a very good definition available at

A rich client is a networked computer that has some resources installed locally but also depends on other resources distributed over the network. The rich client’s configuration is somewhere between that of a thin client, which relies largely upon network-distributed resources, and a fat client which has most resources installed locally.
