First Talk: Sentiment analysis of social media posts using Apache Spark - Niels Dommerholt
Big data is a hot topic and one of the practical applications is sentiment analysis on user submitted content. For companies the awareness of sentiment trends of their user base is of great value.
In this presentation we will give a practical demonstration how we can leverage Spark to analyse a large volume of social media contributions (reddit comments) and demonstrate how we can reduce this data into manageable information.
Apache Spark has shown to be a fast and reliable engine for large scale data processing like this.
We will start with a short high level introduction of how we’re approaching the sentiment analysis. We will show the structure of the data and will be diving into the implementation of our Java code and finally the results of our analysis. Speaker bio Niels Dommerholt

He is passionate about programming, big data and databases and has worked on large big data projects for clients like ING, Philips, the Dutch Forensic Institute and the Dutch Department of Labour.
Besides sharing his knowledge and passion with colleagues, customers and through his blog he’s also fond of sharing it during highly entertaining and passionate sessions at meetup’s and conferences.
Second Talk: Death to null - Ties van de Ven
Most Developers will agree that Immutability is a good concept to adhere to. In reality however, Immutability is scarcely or badly implemented. This presentation will not only show the strength of implementing Immutability in a good way, it will also help you to recognise code patterns where Immutability can be part of the solution.
