We are happy to announce the second RIA forum which will take place in Darmstadt (close to Frankfurt), 23rd of April 2010! This time, with Canoo Engineering AG as premium sponsor, four well known speakers will talk about the advantages and disadvantages of four different ways to create effective user interfaces (especially in business contexts).
Instead of giving details here I recommend to visit the forum page directly: http://www.riaforum.com (in German). Please be aware that we can only provide entrance to a limited audience, so if you want to join, make sure you sign up quickly.

Watch an interesting interview (in German) with Dierk König about the actual language diversity in the Java community — Groovy, Scala, Clojure, JRuby and all the rest of them! If you are interested in this topic, we also recommend to take a look on the schedule of the Java Language Days 2010 (moderated by Dierk König and Markus Völter (itemis).

Excerpt of ”Rich Internet Applications for Business”, an article by Hans Dirk Walter, CEO Canoo Engineering AG (in print).
Even if RIA technology continues to expand steadily in the future and the number of purely HTML based applications does decline, it is nonetheless not recommended to resort to an RIA framework or library for technology’s sake alone when developing online applications. Instead, the decision depends on the user interface requirements.
Figure 1 provides a schematic illustration of various categories of application depending on usage, and shows the dependency of these applications with regard to interactivity requirements and interface richness (UI functionality, drag & drop, graphics).
.
Typical web applications such as online shopping or rail timetables, that are only occasionally visited by their customers, need to be self explanatory and easy to operate. Speed and sophisticated interaction are of secondary importance in these cases. This type of application is best implemented using form based “wizards”. The functionality offered by HTML is generally more than sufficient in such cases. This does not apply, however, to productive systems, whose users often spend several hours per day with the application. The interface need not necessarily be self explanatory, while training is normally worthwhile. These kinds of application should be developed using RIA technology. The final types of program identified are games, which place the most demanding requirements of all in terms of interactivity (extremely speedy program reaction times in response to rapid successive inputs), as well as sophistication (3D animations, film sequences, etc.) Such application have so far scarcely been realised in satisfactory quality as RIAs.

Excerpt of ”Rich Internet Applications for Business”, an article by Hans Dirk Walter, CEO Canoo Engineering AG (in print).
Alongside the ascendancy of the World Wide Web (WWW) as global information platform, its technology has increasingly been employed as the basis for enterprise applications in the course of the last 10 years. Web based application have successively squeezed out the previously widespread client-server applications. Ever more IT managers have recognised the operational advantages of centralised application management (re-)enabled through this technology and have placed a total emphasis upon HTML in their application development. This trend has rather conveyed the impression in recent years, therefore, that page based user interfaces were the last word, while user-oriented layout and design appeared consigned to oblivion.
In the wake of the euphoria surrounding HTML there were always organisations who expressed their dissatisfaction at the shortcomings of pure HTML interfaces. Meanwhile, a significant number of middle sized IT companies made their money developing RIAs for such organisations. Publicly, however, these efforts scarcely attracted attention. It was not until the Eclipse project, with its popular Rich Client Platform (RCP)[1] several years ago, that the ordinary developer was once again reminded of the far more ergonomic interfaces of the client-server technology of the 1980s and 1990s.
The term “rich client” now became newly synonymous with this technology. Since RCP is a “fat client” technology it did not correspond to the centralised “zero footprint”[2] approach of classical HTML applications. These benefits, in which no application specific code whatsoever was of installed on the client, thus employed so called “rich thin client” technology, which in turn however merely represented a transient niche. It was not until Jesse James Garrett coined the phrase “Ajax”[3] in 2005, thus bestowing respectability on JavaScript based Internet technology that the idea of “Rich Internet Applications” became familiar to a broader public, who has since been demanding the same level of interface interactivity in online connections as that of pure desktop applications.
This trend has been reinforced to now by discussions about the fuzzy, yet enigmatic term “Web 2.0”[4]. According to this “hype”, the hitherto largely passive bulk of internet users would become highly active web content authors in the coming years or even site “programmers”. Thus, “Web 1.0 was commerce. Web 2.0 is people. [...] 2015, everyone alive will [..] write a song, author a book, make a video, craft a weblog, and code a program” (Kelly, Wired[5]). However, in order to motivate and enable the average surfer not just to consume but also to actively contribute new content, the web needs to be equipped with a suitable interactive interface, with whose help the user can rapidly and easily become active. RIAs bridge this gap perfectly with respect to the dizzying expectations of Web 2.0. They represent the technology, without which the entire aspiration and utopia would evaporate.
However, RIA technology offers so many advantages not only for the Web 2.0 community but also for everyday enterprise applications, that the demise of exclusively HTML based “poor ugly web applications” (PUWA) is foreseeable in the not too distant future.

Recently, Dustin Marx postet his top ten of the most “Software Development Developments of 2009“. Here is a short summary as a basis for further discussion:
Mergers and Acquisitions: SpringSource acquiring Cloud Foundry, SpringSource itself being acquired by VMware; Oracle‘s acquisition of Virtual Iron and GoldenGate, Microsoft‘s acquiring of Interactive Supercomputing, Google‘s acquisitions of companies such as reCAPTCHA and Teracent, etc.
Changing Landscape of Software Development Conferences: Colorado Software Summit and SDWest and SD Best Practices terminated their long-running tradition in 2009. There is speculation that JavaOne 2009 may have been the last.
Java IDE Wars: IntelliJ IDEA has been the only one of the four leading Java IDEs that has not been available without charge. In 2009, the availability of an open source community edition of IntelliJ IDEA potentially changed the Java IDE landscape.
Groovy: Groovy claims to be “the most popular and successful dynamic language for the JVM”. According to Marx, this certainly seems to be the case (he mentions the high number of books on Groovy (and Grails) and the existence of a DZone area dedicated to Groovy (Groovy Zone) for evidence.
Java EE 6: Marx defines the December release of Java EE 6 as a significant development in the enterprise space.
Oracle buys Sun: According to Marx, even developers who do not use Sun or Oracle products are likely to be at least indirectly affected by this acquisition because it will almost certainly affect the entire software development competitive landscape.
Also included in the ranking were topics as:
- Programming Environments for Mobile Devices
- Bing Search Engine
- Scala
- Java SE 7 News
- Cloud Computing
- Google Chrome OS
If you are interested in Marx’ full review of 2009, please read his blog entry at JW Blogs. He also cited other annual reviews from JavaLobby and Computerworld. So what are last year’s most significant developments in software development from your point of view?
