Assorted Internet Technologies

Trends in the internet of the world, more..

The fallout of an interview for the SWR. Tackles the physical structure, connectedness and bottlenecks (which could be control points as well), countries and people falling into the digital divide, the access problem and the danger of google dominating the world. And some austrian whining on plagiarism in the humanities being supported by google. The diagrams created from the netdimes project are really nice..

Social Intelligence and Social Computers - the future of Computer Science, more...

Inspired by swarm intelligence, human centric computing and the general fear of all things social a short piece on why intelligence is socially based, what kind of role the Internet plays in fostering this type of intelligence and who the enemies are. Includes a discussion of Shirky's "here comes everybody".

Intelligent Web Day at HDM - semantics, search and interaction , more..

The web is an incredible source of information - if it can be tapped. Google is doing it rather successfully. But how can you tap into this well? Machine learning is getting really important in the context of collaborative sites on the web. How can you extract information from web and wikis? How do semantics and search work? How do you use meta-data as annotations to drive new and better GUIs? The answers:

Findability and Collective Intelligence, more..

Two rather new books on social and psychological aspects in search and web applications. The "soft" sciences are really getting into our turf...

Mashups, Gears, Scalability and so on - Google Tech Talks, more...

Use tech talks to learn more on scalability, mashups, model-based-testing etc.

Ideas for a Web3.0 day, more...

Semantics, searching based on different approaches, data-mining and meta-data used by ever more Javascript on the client side. Read more about current projects with UIMA etc.

Xlink instead of Javascript, more...?

Just a short piece on a missed opportunity: could Xlink have done a lot of things that are now done with javascript? Where did the markup for interaction get lost?

Web2.0 Security Information and Questions, more...

Links and critical questions on e.g. how Google does the integration of Google Maps. How does XMLHttpReqeust really work with respect to security? Changes in plans for this? How do you overcome cross-domain-restrictions and still provide security to users? Any help in this area is welcome.

Is there more to user interface design than Model-View-Controller, more...?

Looks like our usability workshop was quite a success. Here are some ideas about what could be done to improve developer awareness. In the summer term we will make a workshop on usability in mobile computing. Contact me if you'd like to present something.

Thesis or lab project: High-availability using J2EE, more ...

Performance and Availability are core requirements in server architectures. How do you achieve this based on open source products (Apache Web Server, Tomcat Servlet Container, JBoss Application Server)?


I am planning to do build a portal lab with Websphere portal server and SAP Portal. If you want to participate here let me know. Clustering, load-balancing, grid technology will be applied in this area but also usability, security etc. play a major role.

Improve your googling, more...

Web searches play such a vital role in research today that it is well worth to improve ones skills in this area. The new book on "100 Google Tips and Tricks" by Dornfaest and Calishain.

Web Mining and Data Warehouses

Data warehouse technology and artificial intelligence in the context of web-mining proved to be very useful for large scale enterprise portals. Unfortunately it became clear that the people involved in building enterprise portals are usually not the same people involved in analyzing the results from a business perspective. The portal is at the same time a means to "sell" things as well as the tool to measure client behavior. This means that a certain GUI items role is overloaded. The talk focuses on text-mining methods since they seem to be the hardest ones and at the same time the most important ones e.g. in case of collaborative portal features (forum, e-mail). And of course, the overall importance of meta-information in a portal becomes clear once again.
