Claudio Huyskens will talk about:
At fedger.io, we built graph technology that autonomously collects data from several sources via API, interprets the data based on an ontology, merges the interpreted data and builds a graph from it. Our technology provides user access to that graph through a visual explorer that allows search, iterative traversing, class-based filtering and graph analytics. We currently run a prototype of that technology that covers the global startup ecosystem in a 10M+ document graph.
I will lay out all the development challenges, we went through during year 1 of fedger.io. This overview will start with a rough technology sketch in early 2013 and will chronologically discuss the major decision points considering technology setup and implementation. My talk will conclude with a presentation of the working prototype and its features.
The next meeting will take place on 05.03.2014 and start from 7.00 pm onwards,

Max Neunhöffer Schönert will talk about: Paxos
In his scientific article The Part-Time Parliament, Leslie Lamport created his Paxos algorithm for distributed voting, inventing a Greek society on the Aegean island Paxos as a whimsical illustration of an otherwise dry subject. He later admitted that the allegory was a dismal failure, in that it failed to pique readers’ interest in the underlying material.

Michael Hackstein will talk about: Graphs, Databases and what we can use them for
Abstract:
The topic of this talk is all about graphs and databases.
We will start of with a definition of the term “graph” and show some use cases were storing your data as a graph is reasonable.
Afterwards we will have an introduction to graph traversals, useful to analyse and query your graph data.
But how can we store data is a graph?
We will solve this question by using ArangoDB, so we have an introduction on how to create a new graph structure and how to transform an existing structure into a graph.
And finally we will use the new graph visualisation tool added to ArangoDB to visualise and explore the data we have just created.
