RAID: Alive or Dead?

RAID: Alive or Dead?

June 8, 2015 | by Geoffrey Noer, Panasas | Comments

Is RAID dead or alive? Are erasure codes replacing RAID for data protection? We present these questions, because some storage vendors promote RAID, while others promote erasure codes. Looking at how vendors are marketing data protection in their products, it almost appears that there is a battle between RAID and erasure code technology and that everyone will agree on a winner at some point.

Winds of Change are Bringing Fresh Solutions to High Performance Data Storage

June 30, 2015 7:53 am | by Michael King, DataDirect Networks | Comments

Large-scale scientific organizations are grappling with the implications of rapid data growth. Massive data collections, analytics and the need for data collaboration are driving the need for high-performance storage solutions that can deliver time to results, fast. A different breed of technologies developed originally for the supercomputing industry are being adapted to meet the needs of technical computing organizations.

How Digital Living Network Alliance can make Life Easier

June 29, 2015 4:43 pm | by John R. Joyce, Ph.D. | Comments

I'm not sure which sounds more ominous, DLNA or Digital Living Network Alliance. Somehow, they both sound very Borg-like. However, in this case, they can actually make your life easier! The Digital Living Network Alliance, normally just referred to as DLNA, is both a non-profit trade organization and a protocol for simplifying the connection of multimedia devices in your home.

WebDAV: Web-based Distributed Authoring and Versioning

June 25, 2015 3:27 pm | by John R. Joyce, Ph.D. | Comments

The World Wide Web was originally developed to be both a readable and writable medium. As the Web developed, for most people it became just a readable medium, as most Web browsers did not support writing to the Web. This created a few obstacles to Tim Berners-Lee's dream to develop an interactive, collaborative, media. However, as obstacles are meant to be overcome, people found various crevices through what was becoming a one-way wall.

Tau proponents say that, for many mathematical problems, tau makes more sense and makes calculations easier.

Are you a Tau-ist? Pi Day is Under Attack

June 23, 2015 4:51 pm | by Suzanne Tracy, Editor-in-Chief, Scientific Computing and HPC Source | Comments

As June 28, 2015, approaches, the Internet is once again anticipating controversy as the mathematical constant pi comes under threat from a group of detractors who will be marking "Tau Day." Tau Day’s revelers are campaigning for a constant twice as large as pi (about 6.28) to take its place, hence the June 28 celebration. Tau proponents say that, for many mathematical problems, tau makes more sense and makes calculations easier.

Anticipating a Major Role for Superconducting Computing

June 22, 2015 4:27 pm | by Elie K. Track and Alan M. Kadin, IEEE Rebooting Computing | Comments

In the past, evolution of computer technology was largely driven by industrial advances in a single technology. That unified approach led to advances on all levels. With the ending of Moore’s Law, this unified approach will inevitably split, leading to a variety of different device technologies, architectures and interface approaches. Within such a mixed environment, we anticipate a major role for superconducting computing.

Tapping at mobile phone games, waking up to sunlight on a pleasant morning or watching a Formula One race — such experiences are at the heart of modern life, and mathematics is working behind the scenes on all of them. Math is also used in many disciplines — from economics to engineering, biology to geography. But many of us struggle with math, and find formulas and theories difficult to grasp. A free online course could help.

MoMATH: Hands-on Mathematics Inspiring Young Minds

My first impression upon entering the National Museum of Mathematics could be described as complete mathematical mayhem. Pre-teenagers were swarming dozens of exhibits in what seemed more like a huge play area than a museum dedicated to the study of an abstract science of numbers, quantity and shapes. However, as I waded in and began to understand specific exhibits, it quickly became obvious that this was a special place.

It's Time to Revolutionize Simulation with Apps

June 18, 2015 3:40 pm | by Brianne Costa, COMSOL | Comments

Throughout history, many revolutions have started with the desire for democracy, and the simulation revolution is no exception. Simulation is an effective way to test the design of a product virtually. It's now evolving into building simulation apps that can be shared across teams, departments and companies. Simulation apps can help organizations in every industry gain better R&D results, while saving both time and money.

As robotic surgery technology continues to advance, so does the need for medical research around the standard of care and true capabilities of the technology in a surgical setting. Many industry leaders, including Fortune 500 companies and the Florida Hospital Nicholson Center, are interested in taking robotic surgery to the next step to allow for telesurgery, or remote surgery.

Shaping your ‘Lab of the Future’ Strategy

June 15, 2015 8:50 am | by Paul Denny-Gouldson, IDBS | Comments

For research and development decision-makers, the ‘lab of the future’ invokes images of huge cost and resources diverted to new and complex systems. Some cite automation and AI as harbingers of the futuristic lab although, fundamentally, these will support scientists — not replace them. Others see mobility as the key issue, but this is not a panacea and, instead, should form part of a multi-platform approach.

A team of German software developers and designers, along with electronics and construction engineers, has developed an innovative design for a new type of electric smart “micro car.” Now in its second-phase, the prototype is able to convert from “traditional driving” to driving sideways in just seconds, with each wheel powered by its own motor. The two-seater also can shrink from eight feet to less than five feet in length.
