When the author started running some years ago, he bought a Garmin Forerunner 405, a device that tracks GPS coordinates while you're running. In this article, you will learn how to store, query, and visualize such data using a Neo4j Spatial datastore and Gephi.

There are many facets to software design. A common example is loss aversion, which refers to "people's tendency to strongly prefer avoiding losses to acquiring gains." Armed with this knowledge, more informed decisions are possible throughout the software development cycle. The following list details a few examples where loss aversion can play a role in software development:
Recently, Datablend open-sourced two new Tinkerpop Blueprints implementations: blueprints-mongodb-graph and blueprints-datomic-graph. Tinkerpop is an open source project that provides an entire stack of technologies within the Graph Database space.
This article looks at the recent mud-slinging (if you can call it that) going on between Hortonworks and Cloudera. It's got to be good news for Hadoop, at least, and it highlights the widespread influence of the open-source Big Data framework.
