Submission + - Largest Known Prime Number -- 17M Digits Long -- Discovered (computerworld.com)

CWmike writes: "A mathematician at the University of Central Missouri has discovered what is now the largest known prime number — one with more than 17 million digits. Dr. Curtis Cooper, who has made two other prime number discoveries, has found the 48th known Mersenne prime — 257,885,161 minus 1. The number is 17,425,170 digits long. Cooper discovered the number on Jan. 25, according to the Great Internet Mersenne Prime Search (GIMPS), a 16-year-old project that uses a grid of computers provided by volunteers to find large prime numbers. If the number was typed out in standard Times Roman 12 point font, it would span more than 30 miles. It also would fill more than six Bibles."
Patents

Submission + - U.S. inventiveness at highest point since Industrial Revolution (computerworld.com) 2

dcblogs writes: U.S tech companies lead all other industries in patent production, and Silicon Valley has the highest patent-producing population, according to a new study by the Brookings Institution. The rate of patenting by U.S. inventors "is at its highest point since the Industrial Revolution." The leading year for patent production was 1916, when 410 patents were awarded for every one million people. Other big inventive years are, in order, 1915, 1885, 1932, but next on the Brooking's list is 2010 and 2011. In 2011, there were about 387 patents awarded per million people. The Brookings report argues that, based on R&D spending, the patenting rate reflects a real increase in the number of valuable inventions and not the actions of companies simply to trying to patent more things. When patent activity is measured on a per capita basis globally, the U.S. ranks ninth behind Sweden, Finland, Switzerland, Israel, the Netherlands, Denmark, Germany, and Japan.

Submission + - A New Computer That Defies Category (computerworld.com)

CWmike writes: "Dell is planning to release by mid-year a sub $100 computer that's all of 3.5 inches long and 1.5 inches wide. It's not much bigger in girth than a USB stick, and is similar in design. This Wi-Fi enabled device is designed to be plugged into something, most likely a monitor or TV. It has two USB ports for a keyboard and a mouse and, alternatively, Bluetooth capability. It displays at 1080p and can support touch screens. The device will be powered by an ARM system-on-a-chip manufactured by an undisclosed vendor. Seen by Dell as a device for working in a cloud-enabled environment, 'Project Ophelia ' was developed by the company's Wyse unit, which is long known for making thin clients. It's a computer that defies category. 'It's a radical rethinking of how best to support end user computing,' said Pund-IT analyst Charles King. It's not simply a thin client device, he says — 'It's steps beyond that.'"

Submission + - RIM Attracts 15,000 Apps For BlackBerry 10 In Two Days (computerworld.com)

CWmike writes: "It's starting to look like the BlackBerry store will be well stocked with apps when Research In Motion launches BlackBerry 10 (see YouTube preview) at the end of this month. The company held an event over the weekend where it offered app developers incentives to port their programs to the BlackBerry 10 platform and managed to attract 15,000 app submissions. 'Well there you have it. 37.5 hours in, we hit 15,000 apps for this portathon. Feel like I've run a marathon. Thanks to all the devs!' wrote Alec Saunders, vice president of developer relations at RIM, in a Twitter message. The 'port-a-thon' event was held in two parts: One aimed at Android developers and the other at apps written in other platforms, including Appcelerator, Maramalade, Sencha, jQuery, PhoneGap and Qt. RIM was offering $100 for each app ported and subsequently approved for sale in the BlackBerry 10 app store, up to certain limits. Developers could also win BlackBerry 10 development handsets and a trip to RIM's BlackBerry Jam Europe developer event."
HP

Submission + - HP Fends Off Lenovo, Reclaims PC Crown (computerworld.com)

CWmike writes: "In its battle for the top spot in the rocky PC industry, Hewlett-Packard has edged out rival Lenovo to take back its leadership position. Last October, HP, which had long held the No. 1 position in the worldwide PC market, suddenly had a challenger: China-based Lenovo. When third-quarter reports came out, one analysis firm had HP retaining its leadership position, while another firm showed Lenovo grabbing the lead spot. Now with fourth quarter numbers out, HP is at the top of both analyst lists again. 'This is a monumental win for HP and it shows that if HP decides to flex their PC muscle, they can at least moderate and even increase share. 'This isn't positive for Lenovo as many market watchers just assumed they would have the No. 1 market share right now,' said analyst Patrick Moorhead. 'Because perception is reality, many will assume something didn't go as planned for Lenovo.'"
Government

Submission + - White House Takes Step Toward Sharing Cyberattack Data (csoonline.com)

CWmike writes: "The White House has issued the National Strategy for Information Sharing and Safeguarding, a framework for agencies and departments to follow that would help bolster defenses against state-sponsored hackers and other criminals (see the plan (PDF)). The move is seen as a small step, albeit an important one. Congress failed this year in passing legislation that would have required utilities and others responsible for the nation's critical infrastructure to share information with federal officials. While lawmakers are expected to revisit the issue next year, the guidelines released Wednesday will begin the process of government entities setting up data-sharing mechanisms. 'This is a good first step,' said Murray Jennex, a cybersecurity expert and associate professor at San Diego State University. 'Other agencies will open up to the NSA and the FBI and such, sharing what has happened to them, where before maybe they wouldn't.' He added: 'And it does free up the FBI to pass on information to other agencies.' Where data sharing within the government would likely fall short: the Department of Defense and the National Security Agency (NSA). Those departments can list information as classified, making it shareable only with authorized people. Therefore, a much more detailed order would be needed to set guidelines on declassifying cyberattack data. The Obama administration is expected in the near future to address the issue of data sharing with the private sector with an executive order. Because the president cannot require companies to share data, the order is seen as a stopgap measure while Congress hammers out much broader legislation. Volunteer sharing of data with the government has fallen short."
Science

Submission + - CERN Scientists Nearly Positive On 'God Particle' Discovery (computerworld.com)

CWmike writes: "Wrapping up the Large Hadron Collider's first three years of work, scientists are nearly positive they've found the elusive Higgs boson, also known as the 'God particle.' Scientists said they are well beyond the regular threshold for verifying the discovery. 'The signal is so strong, the probability of having it wrong is as low as the chance of flipping a coin 40 times and getting 40 heads in a row,' said Sara Bolognesi, a CERN fellow, in a statement. She added that the certainty that they've found the Higgs boson has only been reinforced. However, there is something puzzling about the God particle's measurements that scientists have been taking. Researchers have found the particle decays in two slightly different ways, a discrepancy that could be blamed simply on a 'statistical fluctuation' in their measurements. More tests are planned."

Submission + - McAfee Expelled From Guatemala, Headed Back to U.S. (computerworld.com)

CWmike writes: "The antivirus pioneer John McAfee is headed back to the United States after authorities in Guatemala expelled him earlier on Wednesday for illegally entering the country in an attempt to escape authorities in Belize, where he is wanted for questioning in connection with a murder. In a phone interview with Bloomberg News this afternoon, the 67-year-old said he was being put on an American Airlines flight to Miami on Wednesday afternoon. 'I'm being expelled,' McAfee said in the interview, which appears to have been given just before he was driven to the airport by Guatemalan law enforcement authorities.'I have no choice in the matter,' he said. 'However, I am perfectly happy with the decision.' McAfee said he has recorded an apology to the Guatemalan president 'for putting him in a very slippery position in their negotiation of a peace treaty with Belize.' McAfee, the founder of the antivirus company with the eponymous name, has been on the run from Belize police since Nov. 10th, after his neighbor and fellow American Gregory Faull was found shot to death in his home. Belize police have claimed that McAfee is not a suspect in the murder but only want to question him as a person of interest in the case. McAfee has denied any connection with Faull's death and has consistently maintained that he would be harmed and possibly killed if he were to surrender to Belize police"
Apple

Submission + - A U.S. Apple Factory May be Robot City (computerworld.com)

CWmike writes: "Apple's planned investment of $100 million next year in a U.S. manufacturing facility is relatively small, but still important. Apple has the money, talent and resources to build a highly automated factory that turns out products that are potentially cost competitive with those it now makes in China. Apple has already demonstrated its use of automation in the manufacturing of some of its MacBook products, including the MacBook Air. It was built with what the company calls its 'unibody design' that was crafted from a single sheet of aluminum. A 2009 Apple video of its unibody manufacturing process has glimpses of highly automated systems shaping the metal. In it, Jonathan Ive, Apple's senior vice president of design, talked about the manufacturing process. 'Machining enables a level of precision that is just completely unheard of in this industry,' he said. The importance of robots in warehouse distribution was illustrated in March, when Apple's tablet-making rival Amazon announced an agreement to buy Kiva Systems, a company that also makes autonomous mobile robots to work in warehouses, for $775 million."

dcblogs writes: Apple's planned investment of $100 million next year in a U.S. manufacturing facility is relatively small, but still important. A 2009 Apple video of its unibody manufacturing process has glimpses of highly automated robotic systems shaping the metal. In it, Jonathan Ive, Apple's senior vice president of design, described it. "Machining enables a level of precision that is just completely unheard of in this industry," he said. Apple has had three years to improve its manufacturing technology, and will likely rely heavily on automation to hold down labor costs, say analysts and manufacturers. Larry Sweet, the CTO of Symbotic, which makes autonomous mobile robots for use in warehouse distribution, described a possible scenario for Apple’s U.S. factory. First, a robot loads the aluminum block into the robo-machine that has a range of tools for cutting and drilling shapes to produce the complex chassis as a single precision part. A robot then unloads the chassis and sends it down a production line where a series of small, high-precision, high-speed robots insert parts, secured either with snap fit, adhesive bonds, solder, and a few fasteners, such as screws. At the end, layers, such as the display and glass, are added on top and sealed in another automated operation. Finally, the product is packaged and packed into cases for shipping, again with robots. "One of the potentially significant things about the Apple announcement is it could send a message to American companies — you can do this — you can make this work here," said Robert Atkinson, president of The Information Technology & Innovation Foundation.

Submission + - Happy Bday! SMS Txt Msgs Turn 20 (computerworld.com)

CWmike writes: "In the fast moving world of technology, there are perhaps few things that have proved as resistant to change as the simple SMS text message. While a dizzying number of options exist today to interconnect people, the text message remains a 160 character deliverer of news, gossip, laughs, alerts, and all manner of other information. It connects more people than Facebook and Twitter, has brought down governments, and in so much of the world still holds the ability to change lives. Dec. 3 is the 20th anniversary of the sending of the first SMS text message. Its origins can be traced back to a Danish pizzeria in 1984. Matti Makkonen, a Finnish engineer, was in Copenhagen for a mobile telecom conference and began discussing with two colleagues the idea of a messaging system on the GSM digital cellular system."

Submission + - Dual-Identity Smartphones Could Bridge BYOD Private, Corporate Divide (computerworld.com)

CWmike writes: "Late next year, consumers will be able to buy smartphones that either come with native hypervisor software or use an app allowing them to run two interfaces on the phone: one for personal use, one for work.The technology could help address an issue that has cropped up with increasing frequency at work: Employees who bring their personal mobile devices to work and use them to communicate with clients and to access corporate data. The two approaches to the smartphone virtualization market, however, are different and hinge on whether the software provider is using a Type 1 or Type 2 hypervisor. Lucas Mearian takes a deep dive into this next wave. There will be winners and losers. How do you see it playing out?"
Intel

Submission + - With Otellini Out, New Intel CEO May Bring Fresh Mobile Focus (computerworld.com)

CWmike writes: "Intel CEO Paul Otellini is getting ready to leave the company, and analysts say this could be a good change for the world's largest chip maker. Intel announced on Monday that Otellini, 62, will retire in May after nearly four decades with the company. Whoever takes over as Intel's next CEO will face a daunting job. The company has been struggling to find its way into the burgeoning mobile market and faces tough competition from ARM Holdings, whose processors and technologies are widely used in mobile devices. The company has also been challenged by the depressed PC market. However, Patrick Moorhead, an analyst with Moor Insights & Strategy, said a new leader, whether well-versed in mobile or not, may not change the company, or its future direction, all that much. Intel is such a strong company with a new mobile strategy that the departure of one CEO and the entrance of another shouldn't alter its course much, he said."

Submission + - Windows Chief Steven Sinofsky Leaves Microsoft (computerworld.com)

CWmike writes: "Steven Sinofsky, the executive in charge of Microsoft's Windows 8 operating system and the driving force behind the new OS, is leaving the company effective immediately, Microsoft announced late Monday. Sinofsky was also the public face for Windows 8 and its new Metro interface, posting constant updates in a Windows 8 blog that charted its development. His last post, fittingly, was entitled 'Updating Windows 8 for General Availability.' The OS was officially launched at the end of last month. According to the All Things D blog, there was growing tension between Sinofsky and other members of the Microsoft executive team, who didn't see him as enough of a team player. But Microsoft's official position is that the decision was a mutual one. Sinofsky had only good things to say about his former employer."
