Researchers are working on a lie detector to sniff out false tweets

Sure, some less-than-true statements on Twitter are innocuous, but the social media network’s vast audience means it has huge potential to spread inaccurate, even dangerous, information. Citing examples like the 2011 London riots and accusations of vote-rigging during Kenyan elections, researchers at the University of Sheffield have introduced the concept of a lie detector to analyze information shared on Twitter and other sites.

The EU-funded project, dubbed Pheme, will sort online rumors into four categories: speculation, controversy, misinformation and disinformation. Additionally, Pheme will evaluate sources to determine their authority; tweets from the BBC would hold more weight than an unverified user’s, for example. The system will also search for sources to confirm or deny information in a tweet, following social media conversations about a given topic to eventually determine what’s true and what’s false. Hypothetically, users would be able to view info about a rumor’s accuracy via a virtual dashboard.

To test out of the project, scientists will be running trials with the Swiss Broadcasting Corporation and the Institute of Psychiatry at King’s College London. Clearly, Pheme’s goal is to verify news on a national and even international scale — so your Twitter fibs about amazing weekend plans are safe, for now.

10 Things to Know About Satya Nadella, Microsoft’s New CEO

So it’s official: more than five months after Microsoft CEO Steve Ballmer announced his intention to retire, he has a successor. Satya Nadella, the company’s executive VP of cloud and enterprise, was on lists of potential Ballmer replacements all along, and as higher-profile possibilities like Ford’s Alan Mulally fell off the roster, he went from apparent dark horse to leading candidate to the guy.

Here are some key tidbits to mull over as he gets ready to take on what may be the single most challenging gig in the tech industry.

1. He was born in Hyderabad, India. And moved to the U.S. after graduating from Manipal University. That an immigrant will run this most American of companies is an inspiring story in itself.

2. He’s a longtime Microsoft insider. Nadella joined the company in 1992 from onetime Silicon Valley icon Sun Microsystems; he’s been a Microsoftie for well over half the company’s existence.

3. He’s an engineer. Unlike Steve Ballmer, who was an assistant product manager at Procter & Gamble before joining Microsoft in 1980, Nadella started out as a technologist. He holds a bachelor’s degree in electrical engineering from Manipal University and a master’s in computer science from the University of Wisconsin, Milwaukee.

4. But also a business type. In addition to his technology-oriented degrees, he has a master’s in business administration from the University of Chicago.

5. He’s been promoted again and again. Among his other high-level positions before he was appointed executive vice president for the cloud and enterprise group last year: president of the server and tools business, senior VP of R&D for the online-services division, VP of the business division, senior VP of search, portal and advertising-platform group, VP of development for the business-solutions group, and general manager of consumer and commerce.

Satya Nadella Will Replace Steve Ballmer as Microsoft CEO

Microsoft released a video late Monday introducing the world to Satya Nadella, a 46-year-old who has been at the company for 22 years and is the man chosen to lead after Steve Ballmer’s exit.

“The one thing that I would say that defines me is  I love to learn,” Nadella said in his first interview as Microsoft’s chief. (He will be the technology giant’s third CEO ever.) “I get excited about new things. I buy more books than I read or finish.”

The appointment of Nadella, a native of Hyderabad, India, makes him the most powerful Indian-born tech executive in the world, according to Reuters. It also ends a months-long search that reportedly included such high-profile executives as Ford CEO Alan Mulally and former Nokia CEO Stephen Elop.

Nadella ran Microsoft’s Cloud and Enterprise group, where he was responsible for the firm’s ambitious “Cloud OS” effort to move software and storage from on-site computers to the Internet. Previously, Nadella was president of Microsoft’s $19 billion Server and Tools Business, where he’s credited with spearheading the company’s push toward cloud-computing. Over the last two decades Nadella has worked closely with Ballmer and Microsoft co-founder Bill Gates.

Nadella joined Microsoft in 1992 from Sun Microsoystems, according to the company. He earned a bachelor’s degree in electrical engineering from Mangalore University, a master’s degree in computer science from the University of Wisconsin — Milwaukee and an MBA from the University of Chicago.

Now Nadella faces a stark set of challenges. Microsoft has struggled to keep up with Apple and Google in the booming mobile market. Despite pouring billions of dollars into mobile software and gadgets like the Surface tablet, the company has not been able to find a formula to compete successfully with Cupertino and Mountain View. Last fall, Microsoft announced a $7.2 billion deal to buy Nokia’s mobile phone business.

The latest U.S. mobile device and software market numbers underscore the uphill battle Microsoft faces. Microsoft’s mobile software accounts for a just 3.6% of the market, compared to 81% for Google’s Android platform and 12.9% for Apple’s iOS, according to research firm IDC. And Nokia is nowhere to be found on IDC’s list of the top global smart phone manufacturers, which is dominated by Samsung and Apple.

How to enable .NET Framework 3.0 and 2.0 manually in Windows 8.1 RTM

Windows 8.1 comes with latest version of .NET Framework i.e. 4.5 but, the Windows 8.1 doesn’t come with enabled .NET Framework version 3.0 and 2.0. Some of the desktop utilities still use old 3.0 or 2.0 versions of .NET Framework which can’t work until it is enabled.

Although, whenever the .NET Framework is needed, Windows will ask you to install it from Windows Updates but, it requires internet to be downloaded. Windows 8.1 also asks you to install this feature from Windows Updates but, it fails to download since, the servers are not up yet.

But, the good news is that you can still add .NET Framework 3.0 and 2.0 easily with simple commands without using internet.

Before proceeding to the instructions to enable .NET Framework, you need to fulfill a requirement which has been mentioned below.

  • You will need a Windows 8.1 ISO file which you used to install or upgrade Windows 8.1. This ISO file will work as the source of .NET Framework and Windows will install it from that ISO.

Follow the instructions below to enable .NET Framework 3.0 or 2.0 in your Windows 8.1 RTM.


What is OEM Software?

Answer: OEM stands for “original equipment manufacturer” and OEM software is a phrase that refers to software that is sold to computer builders and hardware manufacturers (OEMs) in large quantities, for the purpose of bundling with computer hardware. The third-party software that comes with your digital camera, graphics tablet, printer or scanner is an example of OEM software.

In many cases, this bundled software is an older version of a program that is also sold on its own as a stand alone product. Sometimes it is a feature-limited version of the retail software, often dubbed as a “special edition” (SE) or “limited edition” (LE). The purpose is to give users of the new product software to work with out of the box, but also to tempt them to purchase the current or fully-functional version of the software.

Log on with both user name and password

Not every user account is meant to be seen by other people. When password-protection just doesn’t cut it and you want that extra bit of discretion, you should hide your accounts from the log-in screen altogether. Here’s how.

It’s not always the best idea to use the same user account for every task. Variety is the spice of life, and having multiple log-ins can help you keep yourself organized. It’s often beneficial to separate the different areas of your digital activities cleanly, such as financial transactions from private conversations. However, these extra accounts don’t have to be seen by everyone. We’ll show you how you can make them invisible by having Windows ask all users to enter both their user name and password instead of just selecting their user symbol.

There are two main methods to do this: Either by going through the registry or by going through the “Local Security Policies” of Windows. Keep in mind that the latter of which will only work on Windows 7 Professional and Ultimate, however.


GUID Partition Table

GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk, using globally unique identifiers (GUID). Although it forms a part of the Unified Extensible Firmware Interface (UEFI) standard (Unified EFI Forum proposed replacement for the PC BIOS), it is also used on some BIOSsystems because of the limitations of MBR partition tables, which use 32 bits for storing logical block addresses and size information.

As of 2010, most current operating systems support GPT. Some, including OS X and Microsoft Windows, only support booting from GPT partitions on systems with EFI firmware, but FreeBSD and most Linux distributions can boot from GPT partitions on systems with either legacy BIOS firmware interface or EFI.

The widespread MBR partitioning scheme, dating from the early 1980s, imposed limitations which affect the use of modern hardware. One of the main limitations is the usage of 32 bits for storing logical block addresses and size information.

For hard disks with 512-byte sectors, the MBR partition table entries allow up to a maximum of 2 TiB(232×512 Bytes).[1] GPT allocates 64 bits for logical block addresses and therefore allows a maximum partition size of 264−1 sectors. For disks with 512-byte sectors, that would be 9.4 ZB (9.4 × 1021 bytes) or 8 ZiB−512 bytes (9,444,732,965,739,290,426,880 bytes or 18,446,744,073,709,551,615 (264−1) sectors × 512 (29) bytes per sector).[1][2]

Intel therefore developed a new partition-table format in the late 1990s as part of what eventually becameUEFI. The GPT as of 2010 forms a subset of the UEFI specification.[3]
