Speakers at #bbuzz 2015 – #1

Every week we are introducing new speakers which will be on stage at #bbuzz 2015. Thanks to our program committee we can present part of our new eclectic program. Presentations range from beginner friendly introductions on hot data analysis topics to in-depth technical presentations about scalable architectures. The conference presents more than 50 talks by international speakers specific to the three tags "search", "store" and "scale".

Talk the Talk: How to Communicate with the Non-Coder

Ellen Friedman is a solutions consultant, speaker and author, currently writing mainly about big data topics. She is a committer to the Apache Mahout project and a contributor to the Apache Drill project.

Describing technical work in non-technical terms does not mean “dumbing it down”. Much to the contrary, it means having sufficiently clear conceptual understanding of your own work and communicating it them to people with a wide range of different background expertise. This talk will examine concrete steps to take to learn how to best communicate the strength of your work to other groups and best conceptualize your own roadmap.
