Hadoop

Hadoop is an open-source software framework for running large batch-oriented information analytics jobs across clusters of commodity servers. Inspired by work at Google and Yahoo!, Hadoop exposes the MapReduce programming paradigm and can also be used with open-source tools from Apache including Hbase, Pig and Hive. Unstructured data stored in Hadoop is distributed and stored multiple times across the Hadoop machine cluster to optimize both performance and reliability.

Big Data: what’s hot, what’s not according to the Twitter stream

Ovum 1/24/2013 – Because (or in spite) of the hype, sentiment about Big Data vendors was generally bullish in 2012. The attention spilled over from IT to the business media. These were among the findings reported by DataSift, which conducted a retrospective analysis of vendor mentions on Twitter during 2012 for Ovum.

Beyond Hadoop

ACM 12/21/2012 – When a new user visits the online music service Pandora and selects a station, the company's software immediately generates a playlist based on the preferences of its community. If the individual creates a Chopin station, for example, the string of songs would consist of the most popular renditions of the composer's music among Pandora's community. Once the new listener inputs a rating, clicking on either the "thumbs up" or the "thumbs down" icon, Pandora factors this preference into future selections. In effect, the service becomes smarter with the vote of each thumb.
