Today, I could have talked about Steve Ballmer’s surprise retirement, or the Moto X or even about Google and Facebook trying to provide Internet access to the entire world. But instead, I will talk about news syndication.
The Dirty Dozen
While it’s not necessary to be dirty, this film tells us one clear thing: you’re stronger with a small team of specialists rather than with a big group of clones. More: you can achieve impossible missions.
We can observe this in innovation every time it comes to reach great, ambitious, disruptive business objectives. It’s a matter of mastering the market context, the behavior of the customers, the way value can be created, to go outside the standard tracks, to know the channels to reach your targets and to exploit every single advantage you have in front of your competitors, might it be in term of timing, vision or technology.
imGraph: A distributed in-memory graph database
In this blog post we briefly describe our new contribution to the big data domain, especially, graph storage and querying. This work was accepted for publication at 2013 ASE/IEEE International Conference on Big Data.
An empirical comparison of graph databases
In recent years, more and more companies provide services that can not be anymore achieved efficiently using relational databases. As such, these companies are forced to use alternative database models such as XML databases, object-oriented databases, document-oriented databases and, more recently graph databases. Graph databases only exist for a few years. Although there have been some comparison attempts, they are mostly focused on certain aspects only.
In this paper, we present a distributed graph database comparison framework and the results we obtained by comparing four important players in the graph databases market: Neo4j, OrientDB, Titan and DEX.

Brussels Cassandra Users
This last Tuesday EURA NOVA hosted an interesting Cassandra meetup. Several tech enthusiasts and Cassandra fans have met each other for two talks: I briefly introduced what are the challenges and potential solution when building a distributed graph layer on top of Cassandra, the second talk, presented by Ansar Rafique, was a general introduction to Cassandra and some performance comparisons against MySQL. Ansar is a PhD student at the department of Computer Science of the Katholieke Universiteit Leuven – Language technology and middleware taskforce (LANTAM) of the DistriNet research group. The talk presented the result of Ansar’s previous researches at Cinnober Financial Technology about factors influencing Read/Write operation in MySQL and Cassandra.
Monthly Buzz – n°4
Apart from an open source language for programming cells and the announcement of Chromecast, a small HDMI stick to stream content on your TV, July was a pretty quiet month (as usual).
Knowledge Sharing
I have been working now for more than 6 months at EURA NOVA, and this article is the opportunity for me to share what I consider to be a key factor of success regarding my integration in the company and the conduct of my work : The way we are creating links and sharing knowledge between colleagues.
“When you hold a hammer, everything begins to look like a nail!”
A few weeks ago, while we were building our high performance computing grid over Graphical Process Unit (GPU), @Nam-Luc enunciated this sentence in order to spotlight one of the most crucial element in a project, whatever it is: the potential irreversibility of a tool choice.
EBISS 2013 @Dagstuhl
This week I was with Amine and Gary at the 3rd European Business Intelligence Summer School organized in the beautiful Dagstuhl castle in Germany. I was present at the two previous editions, it is a great way to have a condensed overview of top-level research in BI. This year two aspects have caught my attention: (1) the ever increasing skills required to be a good “data worker” and (2) the everlasting ontology and semantic web power.
Monthly Buzz – n°3
June was also a very prolific month for tech-related news: the E3, the WWDC where the brand new iOS and MacOS were presented along with an impressive new Mac Pro. Even Huawei chose this month the enter the crowed place of high-end smartphone manufacturers with its P6: “the world thinest smartphone” (so far).
