Excerpt: This is a copy of an answer I left on Larry Page’s Google Plus profile after another announcement about the progress of the self driving car: How come you have a patent for the self driving taxi company in the USA? I always thought of you as a creative role model who wanted to change the world towards a better place. Why not leaving the competition open? I really loved Jonathan Rosenberg’s blog entry in which you ask for openness. This inspired me in my PhD program a lot to make everything open. I was so keen when you announced…

Excerpt: I was just reading through the recent notes of Heinrich which I can recommend to read as well as his old notes. When I stumbled upon the note called Monitor /etc/ using git I was confused. Why would one do this? So I talked to Heinrich and he said: “Well you want to monitor changes of your system config. You want to be able to revert them and you don’t want to care about this when you do something.” I really liked this and thinks its so useful and a smart idea that I wanted to share it with you. Just…

Excerpt: After 2 years of hard work I can finally proudly present the core of my PhD thesis. Starting from Till Speicher and Paul Georg Wagner implementing one of my ideas for next work prediction as an award winning project for the Young Scientists competition and several iterations over this idea which resulted in gaining a deeper understanding of what I am actually doing, I have developed the theory of Generalized Language Models and evaluated its strength together with Martin Körner over the last years. As I will present in this blog article and as you can read in my publication…

Excerpt: There is a trend on the web that artists, start ups (and other people) try to do some crowd founding. I really like the concept. Ask your true supporters, fans, customers to realize the next big project which they will like. But sometimes I have the feeling that especially in music crowd founding might not go as good as possible or to say it simple: People unfortunately have just the attitude expect to get music for free. I am not saying that everyone is participating in peer to peer platforms and doing copyright violations but music as a good is…

Excerpt: Hey everyone I wonder if you could help me out. I am currently at my parents home and there are some old pcs from the time when I was young (even my first very on pc is among them). They might have been bought between 1997 and 2002 and have single core processors starting from 333 Mhz going up to 1800 Mhz. Memory is also varying between 64 MB to 1 GB as is the hard disk. Those computers need way to much energy, the fan is really loud and so on… In general the electronic parts of these computers…

Excerpt: I would like to have an discussion with people that have experience or are interested in MOOCs and Wikiversity. The goal is to checkout the possibilities for creating (otherwise over commercialized) MOOCs in an OER environment (especially wikiversity). Background: According to my former blog post there are  3 ways for creating a MOOC that is truely OER: khan academy wikiversity selfhosting Out of these I would love to discuss what possibilities exist in the context of Wikiversity and how such a MOOC could benefit from the ecosystem of other Wikimedia projects (e.g. books, commons, wikipedia and of course wikiversity itself) I would also love to create a list of…

Excerpt: Even though the reading club on distributed graph data bases stopped I never really lost interest in management of big data and graph data. Due to the development of research grants and some new workers in our group I decided to create a new reading club. (The next and first meeting will be Thursday September 12th 15:30 central European time.) The reading club won’t be on a weekly basis but rather something like once a month. Tell me if you want to join via hangout or something similar! But I would like to be clear: If you didn’t carefully prepare the…

Excerpt: It is almost 2 years over since I published my first ideas and works on graphity which is nowadays a collection of algorithms to support efficient storage and retrieval of more than 10k social activity streams per second. You know the typical application of twitter, facebook and co. Retrieve the most current status updates from your circle of friends. Today I proudly present the first version of the Graphity News Stream Server. Big thanks to Sebastian Schlicht who worked for me implementing most of the Servlet and did an amazing job! The Graphity Server is a neo4j powered servlet with the following properties: Response…

Excerpt: Sorry to start with a conclusion first… To me Titan graph seems to be the egg-laying wool-milk-sow that people would dream of when working with graph data. Especially if one needs graph data in a web context and in real time. I will certainly try to free some time to check this out and get hands on. Also this thing is really new and revolutionary. This is not just another Hadoop or Giraph approach for big data processing this is distributed in real time! I am almost confident if the benchmark hold what it promised Titan will be one of the…
