Dimitris holds a Bachelor in Mathematics and a Master Science in Informatics and Computational Mathematics. A free software advocate for more than a decade, he was Editor-in-Chief of Greek Linux Format and Linux Inside magazines. He likes programming, web development and social network analysis research, and programs in C++ with the powerful Qt toolkit, PHP, Javascript, etc.

He is the CTO of www.iefimerida.gr, the best news/opinion oriented website in Greece and a proud father of two beautiful girls. He loves his wife, Helen.


During 2013 I enjoyed working as technical project manager in OgilvyOne Worldwide, Athens, helping various projects to flourish.

During 2011-2012 I was also entertaining myself as editor in chief of "Linux Inside", which was a bimonthly Greek magazine specializing in Linux and free software. The publication has stopped but we continue our website at http://www.linuxinsider.gr. Before that I was the editor-in-chief of the Greek edition of Linux Format magazine (2005-2008).

In my spare time, I develop Social Networks Visualizer, a cross-platform scientific application for social network analysis and visualization. The project's website is at http://socnetv.org, and the code is hosted at https://github.com/socnetv/app. A copy of the git tree is also imported here in Launchpad: https://code.launchpad.net/socnetv. The application is written in C++/Qt and run in Windows, Mac and Linux. Binary packages are available at http://socnetv.org/downloads.

I have also developed a funny mobile-first tile game, called CMYK3 (http://cmyk3.com), where you must align three same-colored tiles to score.
The game is developed in Javascript/Jquery with some SVG animations.

Last but not least, together with my wife, we maintain a website on greek cuisine full of delicious recipes: http://www.supersyntages.gr as well as a website about dream interpretation (http://www.oneirokriths123.com). If you know Greek, check them out! In this case, you might want to check out http://www.zwdia123.org or http://www.webzein.gr.

SocNetV should implement Katz Centrality to enable the user to measure the degree of influence of an actor in a social network by taking into account the total number of walks between a pair of actors. Katz centrality computes the relative influence of a node within a network by measuring the number of the immediat...
the connectivity definition from the Ucinet context : "Connectivity calculates the number of nodes that would have to be removed in order for one actor to no longer be able to reach another. If there are many different pathways that connect two actors, they have high "connectivity" in the sense that there are multi...
SocNetV should support triad census methods to discern the two types of social capital: brokerage and closure.
For example, I wrote a small shell program that, given a node, extracts only the nodes connected to it along with the connections among them.
