Explaining Big Data

Description: Big Data is the next big thing in computing. This video explains Big Data characteristics, technologies and opportunities.

Due to the issues raised by its volume, velocity and variety, Big Data requires new technology solutions. Currently leading the field is an open-source project from Apache called Hadoop. This is developing a software library for reliable, scalable, distributed computing systems capable of handling the Big Data deluge, and provides the first viable platform for Big Data analytics. Hadoop is already used by most Big Data pioneers. For example, LinkedIn currently uses Hadoop to generate over 100 billion personalized recommendations every week.

What Hadoop does is to distribute the storage and processing of large data sets across groups or “clusters” of server computers using a simple programming model. The number of servers in a cluster can also be scaled easily as requirements dictate, from maybe 50 machines to perhaps 2000 or more. Whereas traditional large-scale computing solutions rely on expensive server hardware with a high fault tolerance, Hadoop detects and compensates for hardware failures or other system problems at the application level. This allows a high level of service continuity to be delivered from clusters of individual server computers, each of which may be prone to failure. Processing vast quantities of data across large, lower-cost distributed computing infrastructures therefore becomes a viable proposition.     READ REST OF STORY

Pros will often talk about rockets to describe white hot stocks. But no stock deserves the moniker more than this one.

We’re talking about Rocket Fuel, a company that lived up to its name when it came public back in September.

“It priced at $29, then opened up immediately at $59.95, before closing out its first day at $56.10, a 93% gain,” Cramer explained.

However, this spaceship quickly came back to earth. “Hideous declines followed. The stock dropped to a low of $37 and change last week,” Cramer added.

It appears investors didn’t know what to make of the company, which – incidentally – has absolutely nothing to do with space flight.  READ REST OF STORY

2.  Would you invest in this company at this time?  Why or Why not?

A powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between — all at the same time.

It sounds preposterous, particularly to those familiar with the yes/no world of conventional computing. But academic researchers and scientists at companies like Microsoft, I.B.M. and Hewlett-Packard have been working to develop quantum computers.  READ REST OF STORY
