What's with the 1s and 0s? Making sense of binary data at scale

Nick is heavily involved in a number of Apache projects, such as Tika, POI and Chemistry, while having the fortune to know many of the people involved in the Apache Big Data and Search space! When not helping out with Apache things, Nick works as the CTO of Quanticate, a Clinical Research Organization (CRO).

Nick will look what a given blob of 1s and 0s actually is – be it textual or binary – and show how to extract common metadata from it, along with text, embedded resources, images, and maybe even the kitchen sink! Therefore, he introduces Apache Tika, along with some other libraries. He will look at how to roll this all out for a large-scale Search or Big Data setup, helping to turn those 1s and 0s into useful content at scale!

Practical t-digest Applications

Ted is PMC member of the Apache Mahout, Apache ZooKeeper, and Apache Drill projects and mentor for Apache Storm, DataFu, Kylin, Flink and Calcite projects. He was the chief architect behind the MusicMatch (now Yahoo Music) and Veoh recommendation systems. He also built fraud detection systems for ID Analytics (LifeLock).

Implementations of t-digest algorithm are easy to use and have been integrated in all kinds of software from ElasticSearch to Apache Mahout. Ted will describe the basic algorithm and demonstrate the effect of some variations of the algorithm.
