A New Approach to Databases and Data Processing

The simplest way to handle more data using more cores (whether on a single machine or in cluster) is to partition it into disjoint subsets, and work on each subset in isolation. In the database world this is called sharding, and it makes scaling relatively simple; only downside is -— it makes writing compellingly complex applications hard.

Forgotten by the Future, Some Take the Internet Into Their Own Hands

The next step, after raising half a million pounds from shareholders, is to convince Lancastrians to pony up about fifty dollars a month for internet service. (Those who invest £1500 or more can get a year’s free service, a tax credit of 30%, and the option to sell the entire investment back in 2016 at full value.) This isn’t AOL dial-up: customers will have access to a blazing fast 1 gigabit connection, something that many city-dwellers, myself included, would covet.

Amdahl’s law

Amdahl’s law is a model for the relationship between the expected speedup of parallelized implementations of an algorithm relative to the serial algorithm, under the assumption that the problem size remains the same when parallelized. For example, if for a given problem size a parallelized implementation of an algorithm can run 12% of the algorithm’s operations arbitrarily quickly while the remaining 88% of the operations are not parallelizable, Amdahl’s law states that the maximum speedup of the parallelized version is 1/1 – 0.12 = 1.136 times as fast as the non-parallelized implementation.

Groupon loyalists are spending more time on the site, which could lift results

The company has been experimenting with creating the same kind of marketplace as Amazon.com Inc. and other e-commerce companies in hopes of getting its customers to shop on its website without relying solely on an email prompt.

So they’re going to compete with Amazon.com.  Good luck with that.

Intel Launches Hadoop Distribution And Project Rhino, An Effort To Bring Better Security To Big Data

Intel says the distribution is optimized for the Intel Xeon processor platform. In its announcement, the company states it can analyze one terabyte of data, which would previously take more than four hours to fully process, can now be done in seven minutes.
