It’s easy to find and create data. But what are you going to do with it? Can I ask the world complex questions such as what’s the local crime rate, distance to metro, or rating of my local school? Can you combine these all together to rate houses you may want to buy? And how do you then connect back to your government and local businesses to engage in collaborative decision making.
This talk with discuss how you should consider users and their personal interactions with data and information. We’ll also peel back the covers on how open source tools such as HBase, Cascading, Geos and Polymaps handle analyzing and streaming realtime data to maps and visualizations both on the web and to mobile devices.
To illustrate what’s possible, we’ll dive through GeoCommons, a large online community of data sharing and community analytics that uses open source mapping visualization, Hadoop analysis, and mobile interfaces to provide this to the world. Users can even build and socialize their own analysis methods to share their expert knowledge with other users. We’ll also review how global organizations like the World Bank and United Nations are using these tools to connect with citizens in developing countries to empower them to make decisions on building investment and understanding how climate science may affect their areas.
Imagine for a moment doing a JOIN on two HBase tables, crazy talk right? Well now you can thanks to Hive. True, it is only meant to be used in a batch context, but we have being doing it for a few months now at StumbleUpon and our analysts and engineers love it. This presentation will cover how the Hive-HBase integration works and how we use it at our company.
In November, Facebook launched a new version of Messages that combines chat, SMS, email, and Messages into a real-time conversation. Facebook relies on Apache HBase, a NoSQL-style database, for storing this real-time message data. This talk will elaborate on our decision process, system configuration, scaling issues, and advantages gained by choosing Open Source.
