Researcher & Programmer. Interested in Semantic Web, Linked Open Data, Information Visualization and Semantic Multimedia. I work mostly with JavaScript, Python and Java. My interest in programming languages (especially dynamic ones) has led me to test/benchmark lots of programming languages and frameworks like Ruby + Ruby On Rails, Groovy + Grails, Scala, and others. Before my PhD I worked as a Java programmer for a number of years in different outsourcing companies from Romania. After I started my PhD studies I discovered they required me to travel a lot (summer schools, workshops, conferences, etc) and at some point I moved to Austria to take a position of Researcher since it was more in line with my new interests. Here I became interested in force directed layouts, charts, diagrams, 3D visualizations in the browser, high performance JavaScript and other visualization topics. Since both my work and my PhD are concerned with Semantic Web, my articles and most of the projects I work for are related to this area. From the semantic stack of technologies I use Sesame, RDF, OWL, SPARQL, reasoning (rules languages, DSLs, different OWL flavours).

comment Does (should?) changing the URI scheme name change the semantics?
In principle different URIs mean different semantics. There is a whole movement today called Linked Open Data that deals with such issues. Take a look at linkeddata.org if you want to understand more.

comment Testing of visualization projects
thanks! we would like to test visualizations in the browser - therefore we really need to check for browser bugs and we need a normal Web testing environment...

I guess you are talking about something like this: froglogic.com/squish/gui-testing/editions/web.php . Thanks for the idea!

You correctly identified some of the challenges. I really love your answer. Can you provide more details about "GUI testing library"? Did you used something like this?

Yes I read most of the important books and articles from Edward Tufte, Stephen Few, Leland Wilkinson, Jeffrey Heer, Mike Bostock, John Resig, and many others...including books about art and psychology by the likes of Rudolf Arnheim, Ernst Gombrich, Eric Kandel...None of them however insists too much on testing visualizations...:( exactly as you said...it's like they're not good or wrong...but some of them certainly have bugs and we need to fix them and just classic software engineering doesn't apply because there might some other subtle bugs...

comment Compilable modern alternatives to C/C++
@kevincline I agree with you, but in many cases my colleagues that work in automotive do use C. I am a Java - JavaScript - Python programmer, so I use C/C++ only when needed...
