In case you don’t have the luck to be in New York around this time, but want to get a glimpse at what’s happening at the Strata Conference listen up: O’Reilly kindly provides live broadcasts from keynotes, talks and workshops. You can see the full schedule of broadcasts here: http://datavis.ch/oBT4EO.
Strata doesn’t ring a bell in your head? It’s one of the biggest conferences focused on data and the business around it organized by O’Reilly.
Strata Conference covers the latest and best tools and technologies for this new discipline, along the entire data supply chain—from gathering, cleaning, analyzing, and storing data to communicating data intelligence effectively. With hardcore technical sessions on parallel computing, machine learning, and interactive visualizations; case studies from finance, media, healthcare, and technology; and provocative reports from experts and innovators, Strata Conference showcases the people, tools, and technologies that make data work.
This is the other reason I buy O’Reilly publications.
