Twitter may censor tweets in individual countries (AP)

Posted: 26 Jan 2012 08:18 PM PST

SAN FRANCISCO – Twitter has refined its technology so it can censor messages on a country-by-country basis.

The additional flexibility announced Thursday is likely to raise fears that Twitter's commitment to free speech may be weakening as the short-messaging company expands into new countries in an attempt to broaden its audience and make more money.

But Twitter sees the censorship tool as a way to ensure individual messages, or "tweets," remain available to as many people as possible while it navigates a gauntlet of different laws around the world.

Before, when Twitter erased a tweet it disappeared throughout the world. Now, a tweet containing content breaking a law in one country can be taken down there and still be seen elsewhere.

Twitter will post a censorship notice whenever a tweet is removed. That's similar to what Internet search leader Google Inc. has been doing for years when a law in a country where its service operates requires a search result to be removed.

Like Google, Twitter also plans to the share the removal requests it receives from governments, companies and individuals at the chillingeffects.org website.

The similarity to Google's policy isn't coincidental. Twitter's general counsel is Alexander Macgillivray, who helped Google draw up its censorship policies while he was working at that company.

"One of our core values as a company is to defend and respect each user's voice," Twitter wrote in a blog post. "We try to keep content up wherever and whenever we can, and we will be transparent with users when we can't. The tweets must continue to flow."

Twitter, which is based in San Francisco, is tweaking its approach now that its nearly 6-year-old service has established itself as one of the world's most powerful megaphones. Daisy chains of tweets already have played instrumental roles in political protests throughout the world, most notably in the uprising that overthrew Egypt's government a year ago.

It's a role that Twitter has embraced, but the company came up with the new filtering technology in recognition that it will likely be forced to censor more tweets as it pursues an ambitious agenda. Among other things, Twitter wants to expand its audience from about 100 million active uses now, to more than 1 billion.

Reaching that goal will require expanding into more countries, which will mean Twitter will be more likely to have to submit to laws that run counter to the free-expression protections guaranteed under the First Amendment in the U.S.

If Twitter defies a law in a country where it has employees, those people could be arrested. That's one reason Twitter is unlikely to try to enter China, where its service is currently block. Google for several years agreed to censor its search results in China to gain better access to the country's vast population, but stopped that practice two years after engaging in a high-profile showdown with Chain's government. Google now routes its Chinese search results through Hong Kong, where the censorship rules are less restrictive.

In its Thursday blog post, Twitter said it hadn't yet used its ability to wipe out tweets in an individual country. All the tweets it has previously censored were wiped out throughout the world. Most of those included links to child pornography.

Samsung 4Q profit rises 17 pct on smartphone sales (AP)

Posted: 26 Jan 2012 09:04 PM PST

SEOUL, South Korea – Samsung Electronics Co. reported a 17 percent jump in fourth quarter profit on the strength of smartphone sales even as the company battled claims it had copied Apple's iPhone.

Samsung said Friday in a regulatory filing that its net profit reached 4 trillion won ($3.5 billion) in the three months that ended in December. The company earned 3.4 trillion won in the same quarter a year earlier.

The Suwon, South Korea-based company said its operating profit jumped 75.8 percent to 5.3 trillion won in the fourth quarter. The figure was closely in line with the company's estimate earlier this month of a 73 percent rise.

"If profit in handsets continues to stream in, this year will also likely be a solid one for Samsung," said Jae Lee, an analyst at Daiwa Securities in Seoul. "The biggest threat would be if the global economy worsens."

Samsung, the world's biggest manufacturer of memory chips and liquid crystal displays, said demand for semiconductors in mobile products and servers remained solid despite weakness in personal computers, which face stiff competition from the rising popularity of tablets.

Samsung has over the decades grown into a key global manufacturer of components that let PCs, digital music players and handsets store data and display it on flat, high-resolution screens. The company has recently been stepping up its challenge against Apple Inc. in the global smartphone business, releasing models such as the Galaxy S II.

Cupertino, California-based Apple, which spurred the smartphone boom with the launch of its iPhone in 2007, has accused Samsung of "slavishly" copying its smartphone and iPad in design, user interface and packaging. Apple sued Samsung in April last year in the United States.

The legal battle has now spilled into 10 countries, according to Samsung officials. Court rulings so far have tended to side with Apple.

Lee said legal battles with Apple would start weighing less on Samsung this year as the South Korean company is expected to release models with new designs.

The quarterly profit brought 2011 net profit to 13.7 trillion won, down 15 percent from the previous year.

Samsung shares rose 0.4 percent to 116,000 won in Seoul.

Facebook, Washington state target online spam (AP)

Posted: 26 Jan 2012 03:13 PM PST

SEATTLE – Facebook is partnering with Washington state to combat a type of spam called "clickjacking" that is plaguing the social networking site, company and state officials announced Thursday.

Two separate lawsuits were filed in federal courts in California and Washington state against Delaware-based Adscend Media LLC, which officials say is behind the spamming.

"The way we think about it, security is an arms race," Facebook's general counsel, Ted Ullyot, said alongside Washington state Attorney General Rob McKenna at the social media company's Seattle offices. "It's important to stay ahead of spammers and scammers."

In "clickjacking," links on Facebook promising shocking or salacious videos have code embedded in them that spreads the link to the user's page. That makes it seem like the user "liked" the link, with the aim of attracting more clicks from the user's friends. The links eventually lead users to a survey or information from an advertiser.

Adscend Media is spreading spam through misleading and deceptive tactics and has encouraged others to do the same, McKenna's office said.

An email inquiry sent to Adscend was not immediately returned, and an attorney for the company had not yet been listed in federal court records.

Social networking sites are popular targets for spammers because people are more likely to trust and share content that comes from people they know. This makes spam, scams and viruses easy to spread.

Still, Facebook says less than 4 percent of content shared on the site is spam. By comparison, about 74 percent of email is spam, according to security company Symantec Corp., though the bulk of it gets filtered out before reaching someone's inbox.

Facebook has more than 800 million users.

Named in Washington state's lawsuit are Adscend co-owners Jeremy Bash, of West Virginia, and Fehzan Ali, of Texas. The lawsuit says Adscend violated several state laws, as well as the federal CAN-SPAM act, which makes it unlawful to procure or initiate transmission of misleading commercial communication.

McKenna said Adscend has annual revenue of $20 million.

Washington state is the only state partnering with Facebook. The company said it partnered with Washington state because of a history in the state of technology consumer protection.

The attorney general said Washington state has been a leader in technology consumer protection since his predecessor, now Gov. Chris Gregoire, began filing suits against malware and spyware users.

"As spammers adjust their tactics, we adjust ours," McKenna said.

NZ court bails two associates of Megaupload founder (Reuters)

Posted: 26 Jan 2012 12:34 PM PST

WELLINGTON (Reuters) – A New Zealand court granted bail on Thursday to two associates of the founder of online file-sharing website Megaupload, accused of being involved in a scheme that allegedly made more than $175 million from Internet piracy and illegal file sharing.

Dutchman Bram van der Kolk, 29, and Finn Batato, a 38-year-old German, who were arrested last Friday along with Megaupload's founder, Kim Dotcom, were freed on bail. A decision on another accused, Mathias Ortman, was put off until Friday pending further submissions on his bail application.

"I am satisfied that the risk of flight here is minimal and such risk as remains can be met by the imposition of strict bail conditions including electronic monitoring," Judge David McNaughton said in a written judgment.

A lawyer for the men had argued their role in the company was different from that of Dotcom, and they did not have secret sources of funds or multiple identities.

The United States wants to extradite all four on charges of Internet piracy, copyright infringement, racketeering and money laundering.

Dotcom, 38, was refused bail on Wednesday because the judge believed there was a significant risk he could try to flee New Zealand. He will reappear in court on February 22. His lawyer is preparing to appeal that decision, maintaining that Dotcom does not have the means to leave the country.

The defendants have said they are innocent of the piracy and other charges, asserting the company simply offered online storage.

An extradition application must be lodged within 45 days of an arrest, and the U.S. must show the alleged offences would be crimes in New Zealand punishable by at least 12 months in jail.

Legal experts have said the extradition process is likely to be long and complex.

Valve ventures into mobile with Steam on iOS and Android (Digital Trends)

Posted: 26 Jan 2012 08:00 PM PST

steam-android

Launched earlier this week and announced on the Steam site, Valve has started a closed beta for Steam Mobile on the iPhone and Android phones. The mobile application brings a vast amount of core functions found within the PC and Mac version of the Steam software, the most notable being the ability to make purchases through the application. This will allow any mobile Steam user to take advantage of the frequent sales that cut popular games up to 90 percent off. Assuming the user agrees to notifications from the application, Steam will also be able to feed mobile alerts to the user when a game on a user's wishlist goes on sale. The interface offers the familiar Steam categories of new, featured, popular and specials. In addition, there's a search interface allowing the user to find games by price, title or genre. 

steam-pricesAfter a user logs into the mobile application, they have the ability to chat with Steam friends, peruse friend activity, read gaming news, check out profiles and groups in addition to looking at screenshots and other gaming media. Within the chat interface, friends are split up into categories such as recent chats, in-game, online and offline. However, group chat is unavailable through this version of the mobile interface. There's also no obvious link between the mobile device and a PC at home that would allow a user to queue up Steam downloads while away from the computer. 

While all of Steam's features aren't included within the application, Valve president Gabe Newell believes that this application represents a good start. Newell stated "Seeing which of your friends are online and playing a game, sending quick messages, looking at screenshots for an upcoming game, or catching a sale – these are all features customers have requested. Mobile is changing way people interact, play games and consume media, and the Steam app is part of our commitment to meet customer demands and expand the service functionality of Steam to make it richer and more accessible for everyone." Newell did not indicate if the Steam platform would start to sell mobile games.

While Steam is moving forward with mobile, Electronic Arts still hasn't rolled out a mobile counterpart to the Origin download service. Origin also lags behind Steam in terms of the amount of games offer for sale on the service. While Steam offers more than 1,800 titles for sale, Electronic Arts lists less than 10 percent of that figure. Electronic Arts did announce an additional 11 third-party publishers have been added to the Origin service recently, but did not indicate how many games would be added over the coming months.  

steam-big-pictureAs reported at CES 2012, Valve is still prepping Steam's "Big Picture" user interface designed to bring the Steam experience to the television screen. This will allow users to hook a computer to the television and play games on a much larger screen, similar to user experience of console owners. Newell hasn't indicated if Valve will release a set-top box to offer this feature to consumers that don't have a computer hooked into their main television in the living room. Some analysts have also speculated that the "Big Picture" mode could utilize cloud streaming technology similar to OnLive and be delivered through an application on gaming consoles or through Internet-connected televisions. However, Valve has said repeatedly that "Big Picture" mode will include controller support. 

While the mobile application is currently in a closed beta, Steam users can download the mobile application onto the iOS platform and log into the application to declare interest in joining the beta. Valve plans to roll out new invites slowly while the application is still being tested over the next few weeks.

Motorola posts loss, awaits Google deal approval (Reuters)

Posted: 26 Jan 2012 03:19 PM PST

(Reuters) – Mobile phone maker Motorola Mobility Inc posted a fourth quarter loss on weak revenue on Thursday in what could be its last report before a planned takeover by Google Inc.

Some Google investors have worried about the search company's decision to buy Motorola Mobility since it warned on January 6 that revenue would fall well short of Wall Street expectations due to legal costs and tough competition from rivals such as the Apple Inc.

The companies are still seeking approval for the deal which is being reviewed by regulators around the world.

Motorola Mobility reported a net loss of $80 million, or 27 cents per share, compared with a profit of $80 million, or 27 cents per share, in the same quarter the year before.

Revenue barely rose to $3.436 billion from $3.425 billion in the year ago quarter.

Set-top box revenue fell 11 percent from the year-ago quarter to $879 million, while revenue from mobile devices rose 5 percent to $2.5 billion.

Google agreed in August to buy Motorola for $12.5 billion, or $40 per share. It wants to get hold of the cellphone maker's patent portfolio to help defend itself and other Android phone manufacturers in patent infringement cases brought by rivals such as Apple and Microsoft Corp.

Motorola Mobility still expects the Google deal to close early this year. The companies are awaiting approval from regulators in several countries, including the United States, China, Europe and Canada.

Motorola said China started phase two of its investigation in December and the European Commission is not expected to announce until February whether or not it will expand its review.

The deal also requires approval from Israel and Taiwan, according to Motorola Mobility, which said that Russia and Turkey have already given their approval.

Since Motorola shares are trading close to the offer price, Morgan Keegan analyst Tavis McCourt said investors appear confident the deal will be approved.

Motorola shares closed up 7 cents at $38.67 on New York Stock Exchange.

After losing ground in the smartphone market for several years, Motorola Mobility was separated from Motorola Inc last year when the company, credited with inventing the cellphone, split in two.

Nintendo chief promises to do Wii U launch right (AP)

Posted: 26 Jan 2012 07:51 PM PST

TOKYO – Nintendo's chief is determined to get right the launch of its next game machine, Wii U, set for this year's holiday shopping season, and acknowledged Friday some mistakes with selling its 3DS handheld.

But Nintendo Co. President Satoru Iwata warned earnings for the fiscal year set to begin April will be the toughest ever for the Japanese manufacturer behind the Super Mario and Pokemon games.

Iwata's remarks come a day after it lowered its annual earnings forecast to a 65 billion yen ($844 million) loss, much larger than the 20 billion yen ($260 million) loss projected earlier. It posted a 77.62 billion yen profit the previous fiscal year.

Iwata blamed the strong yen, which erases overseas earnings, as well as the arrival of smartphones and other devices that offer gaming.

The higher yen slashed nearly 54 billion yen ($701 million) from the company's operating profit for the April-December period.

"I can see how the red ink may be perceived as abnormal," Iwata told analysts and reporters at a Tokyo hotel. "The environment has changed."

The failure of the 3DS handheld, which offers three-dimensional imagery, to take off with enough momentum during the last quarter of 2011 was one of the main reasons for the dismal results, according to Iwata.

The 3DS has gradually started to sell better, but it took a price cut in August. It still lacks a strong lineup of attractive software games, a key factor for a machine to succeed in a big way.

Iwata vowed the company will be better prepared when it introduces the Wii U home console during the 2012 year-end shopping season for a strong comeback.

He declined to give details such as pricing or what the software games available at that time might be.

But he said the Wii U will come with a strong game lineup at the launch as well as secure and safe Internet services that will offer players individual accounts.

The Wii U will come with new ways of playing that will almost make the term "home console" obsolete, Iwata said. It will also offer mobile gaming. The machine has a touch-panel controller.

Nintendo has long competed against rival game makers, such as Sony Corp. and Microsoft Corp. These days, all face the threat from hit devices like the iPad and iPhone from Apple Inc. that also offer games.

Iwata's comments also showed Nintendo is growing less cautious about the Internet, which in the past it had brushed off as mainly for hard-core gamers.

Kyoto-based Nintendo has built its reputation on making games fun to play for casual and newcomer players.

"We are going to put to use our bitter experience with the 3DS," said Iwata.

Will future Apple iOS devices get rid of the 30-pin connector? (Digital Trends)

Posted: 26 Jan 2012 04:15 PM PST

Jon Snyder/Wired The 30-pin connector has become a mainstay of all of Apple's mobile devices, but could it soon be replaced by something more similar to the MagSafe adapter used in the company's laptops? A newly uncovered (thanks to AppleInsider) Apple patent reveals that the company might be exploring incorporating a MagSafe-like adapter into future devices and abandoning the ubiquitous 30-pin connector. The patent also hints at using similar technology with the headphone port. 

The magnetic MagSafe adapters were introduced back in 2006 for Apple's MacBook Pro and were and still are well-loved for the fact that they easily pop into place and similarly pop out of place should someone (or you) trip on your power cord, leaving your laptop safe from any tugs or pulls. The problem with the current 30-pin connector (and headphone jack) is that they prevent the device from being sealed. Both spots have water sensors to detect if some kind of liquid seeped into the device that way, which does happen and is a problem that Apple and consumers would no doubt like to see eradicated. 

The patent shows that Apple would like to use "coded magnets" in both the device and the adapter to share data information across the connection. The use of these magnets would allow the device to be better sealed from water damage, and without 30 pins (literally) sticking out all the time, there would be less room for other damage, like when all of us try desperately to fit our connector cord into the device before realizing that it's backwards. Oops. Using a similar magnet technology in the headphone plug would also allow that port to be better sealed from damage, but would also require new headphones or connector cords, which would be a little bit of a pain. Not to mention that the entire iOS peripheral industry might be a little upset by this change. 

The patent was originally filed in July of 2011, but there's no telling whether this technology will soon be incorporated into iOS devices. If this technology gets us anywhere closer to a waterproof phone immune from spills and drops in the bathtub, then we are all for it.

DirecTV settles dispute with Sunbeam over blackout (Reuters)

Posted: 26 Jan 2012 06:25 PM PST

LOS ANGELES, Jan 26 (TheWrap.com) – DirecTV and Sunbeam Entertainment have broken bread and ended the carriage dispute that caused customers in Boston and Miami to miss both the Packers-Giants NFL playoff game and the Golden Globes earlier this month.

"We are pleased to have reached an agreement to end the Sunbeam blackout, and regret that any of our customers were forced into the middle of a business dispute where they should never have been in the first place," DirecTV said in a statement Thursday. "We believe, like many, the public interest is best served by allowing customers to keep their local broadcast stations as we negotiate future agreements, rather than being denied access by broadcast stations and used as leverage in what should be a private business matter."

The statement added, "The Sunbeam-owned stations - WHDH and WLVI in Boston and WSVN in Miami - are now available for DIRECTV customers in those cities."

The disagreement between the two companies came to a head on January 13 when, unable to reach a deal with DirecTV, Sunbeam pulled its programming from the service. That left customers of Fox affiliate WSVN in Miami and viewers of CW affiliate WLVI and NBC affiliate WHDH, both in Boston, in the dark. In all, approximately 450,000 customers were affected.

Things got ugly on January 15, as both the Golden Globes and the playoff game prepared to air. Customers engaged in a mass Twitter protest throughout the Globes telecast. Meanwhile, Sunbeam rejected a request from DirecTV to air the football game despite the lack of a contract just prior to kickoff.

During the blackout, DirecTV issued a statement to its subscribers saying it was "working hard to bring back your local channel as quickly as possible" -- while adding that Sunbeam was trying to "extort a more than 300 percent fee increase to carry WSVN in Miami, and WHDH and WLVI in Boston."

DirecTV did not disclose the terms of the new agreement.

Are tablet ergonomics a pain in the neck? (Digital Trends)

Posted: 26 Jan 2012 02:50 PM PST

tablet-neck-strain

Now that tablet devices like the Apple iPad, Samsung Galaxy Tab, and Amazon Kindle Fire are becoming commonplace in everyday society, researchers have started examining some of the possible ergonomic impacts of these devices. After all, almost every other technological gizmo and device that has become ubiquitous in society seems to have an impact on our bodies, from desktop computer users suffering carpal tunnel syndrome and circulation problems to gamers and "Generation Text" experiencing thumb and wrist injuries. Before then, centuries of people wore down their bodies on telephone and telegraph gear, industrial machinery, looms, and countless other devices. Why should tablets be any different?

According to researchers at the Harvard School of Public Health, they aren't. A new study (PDF) published this month in Work: A Journal of Prevention, Assessment, and Rehabilitation is among the first to look at the possible ergonomic impacts of tablet use, and there's good news and bad news. The good news is that tablet users seem to shift position and move around more than folks locked in to traditional desktop and notebook computers. The bad news is that most common ways of holding and using tablets seem to put considerable strain on users neck muscles — especially compared to typical desktop computing setups.

What did the Harvard team find, and what can tablet users do to protect themselves?

Tableta rasa

The Harvard study is among the first to look at the ergonomics of using a tablet, and its scope is necessarily limited: It only examines the effects of tablet use on the head, neck, and shoulders while seated in a relatively deep lounge-style chair, with a slightly reclined back and no arm rests. A myriad of other parts of the body (like the hands, arms, and the back) weren't considered, nor were a number of other postures and ways people use tablets, such as standing, walking, lying flat, perched on a stool, crammed into an airplane or bus seat, and many more.

To look at the effects of tablet use, researchers wired up subjects with a infrared three-dimensional motion analysis system (think of it as something akin to the motion capture systems used in movies), and asked subjects to perform a range of tasks with tablets in four different positions:

  • Lap Hand: User holds the tablet in their lap without a case, supported (or not) by their hand
  • Lap Case: Tablet sits on the lap with its case set to its lowest angle
  • Lap Table: Tablet rests on a table with its case set to its lowest angle
  • Table-Movie: Tablet rests on a table with its case set to its highest angle (for media viewing)
The researchers came up with four basic tasks—Internet browsing and reading, playing a game (solitaire), composing short replies to email messages, and watching short videos. Not all tasks were performed in all positions. The video-watching task, for instance, was exclusive to the Table-Movie position. Subjects didn't watch videos in the other positions, nor did they have to surf the Web, play a game, or write email in the Table-Movie position.

Harvard tablet ergonomics positions

So what tablets were used? The researchers picked two: an Apple iPad 2 with a Smart Case running iOS 4.3 and a Motorola Xoom tablet with Motorola's Portfolio Case running Android 3.0.

The tilt angles offered by the cases are quite a bit different: the iPad Smart Cover can handle tilt angles of 15° and 74°, while the Motorola Portfolio case does angles of 45° and 63°. As we'll see, that might make a big difference.

Flex Time

Overall, the researchers found that subjects came closest to generally-accepted neutral ranges of head and neck flexion in the Table-Movie posture, with the neck being well within neutral values and the head falling just inside it. However, for the three other postures, subjects' head and neck flexion fell some 15 to 25 degrees outside the neutral range. Users tend to hold their heads out and look downward when using a tablet on their laps or on a tabletop. That, in turn, puts stress on the neck muscles, far more strain than someone using a traditional computer, who can maintain a more-or-less neutral position where the weight of their head is supported by the bones of the neck and spine, rather than muscles.

Harvard tablet ergonomics angles

Generally speaking, using a tablet on a tabletop (the Table-Case posture) rather than a lap resulted in a lower cranio-cervical angle — meaning their heads tended to be more aligned vertically with their spines.

However, there were significant variations between the iPad and its Smart Cover and the Motorola Xoom and its Portfolio Case, and they don't bode that well for iPad users. Angles of neck and head flexion were significant higher for the iPad 2 with Smart Cover in both the Lap-Case and Table-Case postures when compared with the Xoom and its case. Presumably, the Smart Cover's lower angle (25° compared with 45°) meant users held their heads and necks at at more of an angle. Similarly, the researchers found iPad users had a significantly lower gaze angle in the Lap-Case and Table-Case postures. Researchers also found that iPad users put the iPad significantly lower and closer to them than they put the Xoom in the Lap-Case and Table-Case postures — again, probably influenced by the Smart Case's flatter orientation. Researchers found that subjects consistently positioned the Xoom so their viewing angle of the tablet was nearly perpendicular for all four postures, meaning their view of the tablet's screen was more-or-less flat. However, in the Lap-Case and Table-Case postures, iPad users tended to have a more oblique view of the screen.

Just in case

Although the study only examines a few ergonomic factors associated with tablet use, one result that jumps out is that cases make a big difference if you're going to use a tablet on a table or on your lap. Although Apple's Smart Cover offers two significantly different viewing angles, its shallow 25° tilt intended for typing seems to make users more prone to hunching over their tablet, putting strain on their neck. (That's not to knock Apple's Smart Cover exclusively; the same thing likely applies to other tablet cases that offer shallow use angles.) However, that doesn't necessarily mean a steep tilt is better. It doesn't take much more than a glance at someone using a tablet at a 45° angle on a tabletop to realize trying to use an onscreen keyboard at such a tilt is difficult— and likely hard on the wrists over time.

Another interesting finding is that the only posture in the study where subjects exhibited neutral values for their neck and head angles was the highly-angled, passive Table-Movie posture. Put another way, the least stressful way to interact with a tablet is not to interact with it at all: Just prop it up and look at it.

Safe tableting

As more people rely on tablets for everyday communications and tasks — and are using them to replace things like netbooks, notebooks, and even traditional desktop computers — they're spending more and more time with the devices, increasing their risk of stress and injury from prolonged use. So, the best advice for using a tablet over the long term likely derives from all the ergonomics lessons we've learned from PCs, gaming, and other tasks:

  • Try to keep your upper body posture neutral and well supported. Keep your neck straight, your shoulders relaxed, and your arms positioned near your sides.
  • Part of the "tablet hunch" comes from placing them them well below the field of vision when we're in a neutral posture. If you're using a tablet for a long time, consider adjusting your seating or the position of the tablet so it's at or just below your field of vision when you hold your head and back at a neutral angle. That may mean positioning the tablet well above a table or desk surface, just like many people do with notebooks (with or without desktop docking stations).
  • It may look silly, but for long periods of use, using a separate keyboard rather than on on-screen keyboard is probably a good idea to help maintain good ergonomics. You don't have to take it with you everywhere you go like some 21st century version of a pocket protector, but if you find yourself doing long writing or messaging sessions on a tablet, a keyboard might be a good idea.
  • Move around. Tablets are inherently portable devices, and people take them everywhere they go, so that means tablet users are more likely to shift position, get up, walk around, and change their posture than a typical desktop PC user who might stay in a chair for hours at a time. Whether using a desktop, notebook, gaming console, or tablet, frequent breaks to stretch, move around, and get blood flowing are critical. Use it or lose it.

What's next

Reports have the Harvard team next looking to examine the effects of tablet use on the arms and wrists, which could be even more interesting. And, just in case folks were wondering, the study was partially funded by Microsoft, which is looking to make a big splash in the tablet market with Windows 8 later this year. (Although two Microsoft researchers helped design the study, they didn't participate in data collection or analysis.)

McAfee rejects Symantec claim about market share (Reuters)

Posted: 26 Jan 2012 01:33 PM PST

BOSTON (Reuters) – Security software maker McAfee rejected a claim that several large corporate customers had recently switched over to using products from rival Symantec Corp.

Symantec Chief Financial Officer James Beer told Reuters in an interview late on Wednesday that his company was taking share in the anti-virus software market away from McAfee, which was purchased by chipmaker Intel Corp in February.

Beer said that several large McAfee customers had switched to Symantec during the quarter, but declined to identify them.

McAfee Senior Vice President for Finance and Accounting Edward Hayden told Reuters on Thursday that the claim was false. He added that his company had booked a record amount of business in its December quarter, signed its biggest deal ever and closed more sales over $1 million than it had in any single period.

"We are not aware of any major account that we lost to Symantec during the quarter," he said.

Intel bought McAfee in a $7.7 billion deal meant to spur growth at the world's top chipmaker and also help it better protect its products from hackers. Investors are still waiting to see whether that bet will yield results.

McAfee laid off about 3 percent of its workers, or about 250 employees, in December.

Hayden said that the company is now adding staff in priority areas including mobile technology, cloud computing and network security.

He said he expects the staff to return to its pre-layoff level of about 7,000 by the end of the first quarter.

European Lawmakers Want "Right to Be Forgotten" on Facebook, Google (Mashable)

Posted: 25 Jan 2012 12:30 PM PST

European Internet users may be getting better control over information posted online, thanks to some proposed sweeping reforms lawmakers proposed Wednesday designed to protect digital privacy. The suggested law calls for a "right to be forgotten" and a "right to data portability." The former would require Internet companies such as Facebook and Google to completely wipe all of a user's info from their servers if such a request was made. The latter demands users be allowed to easily transfer data from one online service to another, a currently difficult task.

The "right to be forgotten" wouldn't be granted to users attempting to remove information relevant to a criminal investigation.

All online businesses operating in Europe would be bound to the new rules, whether or not they're based on the continent. Should web services fail to comply with these rights, they would be slapped with fines of up to €1 million or up to 2% of the global annual turnover of a company (The total value of all products made in a 12-month period).

In the past, European Union (EU) member states have issued varying interpretations on existing digital privacy laws. Those different analyses have resulted in discordant levels of enforcement from country to country. If passed, this law would unify all 27 EU member states under a single set of privacy rules.

The EU argues this Europe-wide standardization would save businesses money by providing a sole definitive source of online privacy law for the continent. However, many internet companies depend on access to users' data for advertisement revenue.

A spokesman for European Union justice commissioner, Viviane Reding, told the BBC that the proposed laws are a means of protecting children and young adults who share details online which they later want removed for professional or personal reasons.

"These rules are particularly aimed at young people as they are not always as aware as they could be about the consequence of putting photos and other information on social network websites, or about the various privacy settings available," said spokesman Matthew Newman.

For the proposed new rules to become European law, they will need approval from the EU's member states followed by ratification from European Parliament. That process may take up to two years.
