5 reasons to upgrade to Windows 8.1

The Windows 8.1 preview is here, giving us a first-hand glimpse at the fruits of Microsoft’s newfound rapid-release religion. Remolding an operating system in eight scant months is a tall task indeed, and while Windows 8.1 is still far from perfect, Microsoft managed to craft a fairly capable reimagining of its new-look OS in the short time since Windows 8 debuted last October. 

INTERNET TECHNOLOGY BASICS

How does the Internet Works?

The internet is a worldwide collection of computer networks, cooperating with other to exchange data using a common software standard. Through telephone wires and satellite links, internet users can share information in a variety of forms. The size, scope and design of the internet allow users to:

• Connect easily through ordinary personal computers and local phone numbers;
• Exchange electronic mail (E-mail) with friends and colleagues with accounts on the internet;
• Post information for others to access, and update it frequently;
• Access multimedia information that includes sound, photographic images and even video; and
• Access diverse perspectives from around the world.

An additional attribute of the internet is the\at it lacks a central authority – in other words, there is no “internet, Inc.” that controls the internet. Beyond the various governing boards that works to establish policies and standards, the internet is bound by few rules and answers to no single organization.

The History of the Internet

How To Make Your Phone Untappable

In 1991, Philip Zimmermann developed a humble-sounding electronic encryption technology known as Pretty Good Privacy. In fact, it was very good–so good that not even the federal government has been able to crack it, a fact that has made Zimmermann a folk hero to privacy advocates and a headache to law enforcement.

Now Zimmermann, a fellow at Stanford Law School’s Center for Internet and Society, has found himself back in the fiery debate between federal investigators and those who oppose their snooping–this time thanks to ZRTP, a technology for encrypting Internet telephone calls. ZRTP throws a wrench in the Bush administration’s controversial warrant-free wiretapping program and its proposed legal immunity for the telecommunications companies. So far, not even teams of supercomputers and cyberspies at the National Security Agency have cracked ZRTP. That means anyone who uses Zimmermann’s Zfone software, a ZRTP-enabled voice over Internet Protocol (VoIP) program available for free on his Web site, can skirt the feds’ wiretapping altogether.

Google Balloon Project Gets Off The Ground

Google has unveiled plans to provide the internet to the billions who cannot currently access the web - using balloons circling the globe.

The internet giant's secretive X research lab is behind the move, called Project Loon in recognition of how strange the idea sounds.

Scientists launched a trial on Saturday in New Zealand's South Island, letting off a string of jellyfish-shaped balloons in the sky about Lake Tekapo.

The aim is for the flimsy helium-filled inflatables, which are made from plastic film, to beam the internet back down to earth as they sail past on the wind.

Samsung Reveals S4 Galaxy 4G 'Double Speed'

 

Electronics giant Samsung plans to sell a variation of its flagship Galaxy S4 smartphone that will transmit data at nearly twice the normal speed, it has confirmed.

China Builds World's Fastest Supercomputer

China has built the world's fastest supercomputer, almost twice as fast as the previous US holder and underlining the country's rise as a science and technology powerhouse.



The semiannual TOP500 official listing of the world's fastest supercomputers released Monday says the Tianhe-2 developed by the National University of Defense Technology in central China's Changsha city is capable of sustained computing of 33.86 petaflops per second.

That's the equivalent of 33,860 trillion calculations per second. The Tianhe-2, which means Milky Way-2, knocks the US Department of Energy's Titan machine off the  №1 spot. It achieved 17.59 petaflops per second.

Supercomputers are used for complex work such as modeling weather systems, simulating nuclear explosions and designing jetliners.

It's the second time China has been named as having built the world's fastest supercomputer.
In November 2010, the Tianhe-2's predecessor, Tianhe-1A, had that honour before Japan's K computer overtook it a few months later.

The Tianhe-2's achievement shows how China is leveraging rapid economic growth and sharp increases in research spending to join the United States, Europe and Japan in the global technology elite.

"Most of the features of the system were developed in China, and they are only using Intel for the main compute part," said TOP500 editor Jack Dongarra in a news release accompanying the announcement.

"That is, the interconnect, operating system, front-end processors and software are mainly Chinese," said Mr Dongarra, who toured the Tianhe-2 development facility in May.

Scrabble app changes anger players on Facebook

Thousands of players have taken to Facebook to complain about changes made to a popular mobile Scrabble app.

The changes have been made by Electronic Arts (EA), which took over the running of the app from Scrabble brand owner Mattel at the end of May.




Players are angry that their player histories have been wiped, the dictionary has changed and the board no longer refreshes itself after a turn.

Mattel apologised but added that the update had also attracted new players.
The firm said new features included the ability to play the game in six languages, customise the board, and pay for an ad-free version.

The game also uses the Collins dictionary rather than the traditional Chambers edition.

The app's official page on Facebook has more than 3.6m "likes" but most of these were amassed before the update and almost all of the recent comments are from players asking for the old version to be returned.

A Facebook group set up by players called "please bring back the Scrabble we love" has more than 2,000 members.

Intelligent robot system recycles waste

A robotic recycling system could help address the escalating global waste problem, according to Finnish technology company ZenRobotics.

The ZenRobotics Recycler (ZRR) is an intelligent robotic system which separates construction materials on a conveyer belt, plucking out recyclable materials and depositing them in bins for collection. The system is designed to replace manual sorting, which can be dangerous and frequently prohibitively expensive.

Scientists uncover ‘God’s bathtub’

Imagine a lake that's never been affected by climate change or any other man-made influences. Australian scientists say they have found just that—a remote lake whose crystal-clear waters seem to be in the same chemical state as they were about 7,500 years ago.

How to upgrade Iphone

The iPhone touchscreen smartphone device first appeared on the market in 2007. This phone handles software upgrades a bit differently than most smartphones. Instead of sending out software updates over the air, Apple instead requires iPhone users to download and install the latest firmware through iTunes. If you'd like to update your iPhone's firmware, you can do so in a few steps.

BLACKBERRY SOFTWARE UPDATE HANGING ; How To Solve It.

Yesterday, a friend beeped my line and was seriously lamenting for help on his Blackberry Bold 5 device; I was curious to know what actually happened and he said, when he attempted to upgrade his device software, the BB just stopped at 16% back –up for over three hours. He said he remove the battery and inserted it again, but the problem software update page still remain on screen. I quickly instructed him to give me a couple of minutes, while I ran a check on his Device.
