Submission + - IBM launches first new mainframe in 3 years (wired.com)

Submitted by HockeyPuck
HockeyPuck writes: IBM has just launched their newest mainframe, the first in 3 years. The z13 powered by up to 12 Z CPUs each having with 12 cores and each core managing 8 threads simultaneously accessing 10TB of RAM. Additionally, there are 11 Level-3 caches on chip and a custom chipset called Centaur that provides a level 4 cache with 410 GB/s memory bandwidth. It includes hardware engines dedicated to encryption and providing analytics of transactions in real-time, all while being able to support 8,000 virtual machines.

Submission + - The Mainframe is Dead! Long Live the Mainframe! 1

HughPickens.com writes: The death of the mainframe has been predicted many times over the years but it has prevailed because it has been overhauled time and again. Now Steve Lohr reports that IBM has just released the z13, a new mainframe engineered to cope with the huge volume of data and transactions generated by people using smartphones and tablets. “This is a mainframe for the mobile digital economy,” says Tom Rosamilia. “It’s a computer for the bow wave of mobile transactions coming our way.” IBM claims the z13 mainframe is the first system able to process 2.5 billion transactions a day and has a host of technical improvements over its predecessor, including three times the memory, faster processing and greater data-handling capability. IBM spent $1 billion to develop the z13, and that research generated 500 new patents, including some for encryption intended to improve the security of mobile computing. Much of the new technology is designed for real-time analysis in business. For example, the mainframe system can allow automated fraud prevention while a purchase is being made on a smartphone. Another example would be providing shoppers with personalized offers while they are in a store, by tracking their locations and tapping data on their preferences, mainly from their previous buying patterns at that retailer.

IBM brings out a new mainframe about every three years, and the success of this one is critical to the company’s business. Mainframes alone account for only about 3 percent of IBM’s sales. But when mainframe-related software, services and storage are included, the business as a whole contributes 25 percent of IBM’s revenue and 35 percent of its operating profit. Ronald J. Peri, chief executive of Radixx International was an early advocate in the 1980s of moving off mainframes and onto networks of personal computers. Today Peri is shifting the back-end computing engine in the Radixx data center from a cluster of industry-standard servers to a new IBM mainframe and estimates the total cost of ownership including hardware, software and labor will be 50 percent less with a mainframe. “We kind of rediscovered the mainframe,” says Peri.

Submission + - Carnivorous pitcher plant "out-thinks" insects (discovery.com)

Submitted by schwit1
schwit1 writes: A carnivorous pitcher plant is changing its behavior in response to natural weather fluctuations, allowing it to give up its prey in order to capture more.

The pitcher plant, which has liquid-filled leaves shaped like funnels, has the ability to allow some of its prey, such as ants, to escape by “switching off” its trap."

The first ant reports back to the other ants that it found a large batch of sweet nectar, causing a large contingent of ants to descend upon it. If the trap captures the first ant, it won’t be able to capture many more ants later.

Submission + - Building a better bike helmet out of paper

Submitted by Anonymous Coward
An anonymous reader writes: Inspired by nature, a London man believes the solution to safer bike helmets is to build them out of paper. '"The animal that stood out was the woodpecker. It pecks at about ten times per second and every time it pecks it sustains the same amount of force as us crashing at 50 miles per hour," says Surabhi. "It's the only bird in the world where the skull and the beak are completely disjointed, and there's a soft corrugated cartilage in the middle that absorbs all the impact and stops it from getting a headache." In order to mimic the woodpecker's crumple zone, Anirudha turned to a cheap and easily accessible source — paper. He engineered it into a double-layer of honeycomb that could then be cut and constructed into a functioning helmet. "What you end up with is with tiny little airbags throughout the helmet," he says.'

Submission + - Doctors Say Food Stamp Cuts Could Cause Higher Healthcare Costs 4

Submitted by Hugh Pickens DOT Com
Hugh Pickens DOT Com writes: Lauran Neergaard writes at the Christian Science Monitor that doctors are warning that if Congress cuts food stamps, the federal government could be socked with bigger health bills because over time the poor wind up seeking treatment in doctors' offices or hospitals as a result. "If you're interested in saving health care costs, the dumbest thing you can do is cut nutrition," says Dr. Deborah Frank of Boston Medical Center, who founded the Children's HealthWatch pediatric research institute. "People don't make the hunger-health connection." Food stamps feed 1 in 7 Americans and cost almost $80 billion a year, twice what it cost five years ago. The doctors' lobbying effort comes as Congress is working on a compromise farm bill that's certain to include food stamp cuts. Republicans want heftier reductions than do Democrats in yet another partisan battle over the government's role in helping poor Americans. Conservatives say the program spiraled out of control as the economy struggled and the costs are not sustainable. However research from the Robert Wood Johnson Foundation and The Pew Charitable Trusts estimated that a cut of $2 billion a year in food stamps could trigger in an increase of $15 billion in medical costs (PDF) for over the next decade. Other research shows children from food-insecure families are 30 percent more likely to have been hospitalized for a range of illnesses. "Food is medicine," says Massachusetts Representative Jim McGovern, who has led the Democrats' defense of the food stamp program. "Critics focus almost exclusively on how much we spend, and I wish they understood that if we did this better, we could save a lot more money in health care costs."

Submission + - New Powers Coming For 007: Driving Over The Speed Limit (telegraph.co.uk)

An anonymous reader writes: The Telegraph reports, "Britain’s spies are to be given a “licence to speed” for the first time, under changes to motoring laws. While James Bond would no doubt have scorned such niceties, officers in MI5 and MI6 are currently required to obey the rules of the road, even when national security is under threat. Now Robert Goodwill, the transport minister, intends to add the Security Service and the Secret Intelligence Service to the group of agencies with permission to break the speed limit."

Submission + - Regex Golf, XKCD And Peter Norvig (i-programmer.info)

Submitted by mikejuk
mikejuk writes: A recent xkcd cartoon has started some deep academic thinking. When AI expert Peter Novig gets involved you know the algorithms are going to fly. Code Golf is a reasonably well known sport of trying to code an algorithm in the shortest possible code. Regex Golf is similar, but in general the aim is to create a regular expression that accepts the strings in one list and rejects the strings in a second list. The xkcd cartoon in question http://xkcd.com/1313/ revealed that this is but the first step. Programmers like recursion and a regex is a string after all and a regex can process a string so a regex can process a regex and this means you can have meta-regex golf and meta-meta-regex golf.... Yes my friend, it's regexes all the way down!
The hover over text gives a regular expression that matches the last names of the elected US presidents, but not the losers. This started Peter Norvig, the well-known computer scientist, director of research at Google and wearer of brightly colored shirts, thinking about the problem. Is it possible to write a program that would create a regular expression to solve the xkcd problem? The result is an NP hard problem that needs AI like techniques to get an approximate answer.
To find out more read the complete description, including Python code, at Peter Norvig's blog post http://nbviewer.ipython.org/url/norvig.com/ipython/xkcd1313.ipynb which ends with the challenge:
"I hope you found this interesting, and perhaps you can find ways to improve my algorithm, or more interesting lists to apply it to. I found it was fun to play with, and I hope this page gives you an idea of how to address problems like this."

Submission + - SpaceShipTwo sets a new altitude record

An anonymous reader writes: Virgin Galactic’s SpaceShipTwo reached an altitude of 71,000 feet, beating out its previous record of 69,000 feet. From the article: 'This time around, Virgin Galactic and Mojave-based Scaled Composites, the plane's builder, tested a new reflective coating on the rocket plane's tail booms. The flight also marked the first tryout for a thruster system that's designed to keep the plane on course when it's above the atmosphere. Virgin Galactic said all of the test objectives were met.'
