Doing things the smart way requires good visibility, so we had to start doing big data. Or should we say big information, since any fool can collect massive amount of data, the trick is in converting big data into small and […]
By Stephen Goldsmith & Christopher Kingsley.Chances are very good that the last call you received from a congressional campaign was personal. A volunteer chose your seven-digit number, out of thousands in the ward, because an algorithm comparing dozens of data points on when you registered, how you’ve voted, and what kind of truck you drive suggested that you were persuadable. […]
By Andrew Crotty, Alex Galakatos, and Tim Kraska, Brown UniversityThe increasing prevalence of big data across all industries and sciences is causing a profound shift in the nature and scope of analytics. Increasingly complex computations, ranging from machine learning to predictive modeling, are fast becoming the norm. Users commonly express such tasks as a collection of user-defined functions (UDFs), preferably written in […]

Share This articleWe all know that with enough expensive servers, big companies can crunch through massive amounts of data. In some cases, like trending search reports, dedicated computing resources can even make large-scale analysis happen in realtime. Now, startup Map-D has harnessed the power of GPUs to allow the realtime analysis and visualization of huge datasets with a much smaller […]

Big Data was one of the biggest buzz-words in the technology sector in 2013. The term refers to management of vast quantities of unstructured data, i.e. information available […]
Despite the deafening buzz around hyperscale and OpenStack, the Big Data ecosystem continued along on its path of growth this week, with Altiscale pulling the curtains back on a hosted platform built from the ground up to run Hadoop.The newly launched Altiscale Data Cloud is designed specifically for organizations that lack the technical expertise of their web-scale peers but face […]
As computers enter ever more areas of our daily lives, the amount of data they produce has grown enormously. But for this “big data” to be useful it must first be analyzed, meaning it needs to be stored in such a way that it can be accessed quickly when required.

Elasticsearch is an open source, distributed real-time search and analytics engine for the cloud. It’s built on Apache Lucene search engine library and provides full text search capabilities, multi-language support, a query language, support for geolocation, context aware did-you-mean suggestions, autocomplete and search snippets.Elasticsearch supports RESTful API using JSON over HTTP for all of its operations, whether it’s search, analytics […]
After 150 million theoretical calculations, scientists at Harvard University in the US reveal results that could cut down the time and cost of experimental tests to find better organic electronic materials for solar cells.Most solar cells are made from expensive inorganic materials. Solar cells from organic materials are a cheaper alternative and scientists have been working to find designs that […]
