Huawei Ascend P6 Preview


The Huawei Ascend P6 is the Chinese company’s latest flagship smartphone, and is the worlds slimmest, at just 6.18mm thick.

However, while flagship for Huawei, the Ascend P6 is more of a premium mid-range handset in terms of features and design. Its screen is 720p rather than 1080p and, quite astonishingly considering the time of its launch, it lacks 4G LTE, but on the other hand its chassis is finely crafted from aluminium. To find out just what the deal is, we got hands on.

Huawei Ascend P6 Preview

One thing that is clear about the Huawei Ascend P6 is the influence from Apple. This phone sports machined aluminium sides and back and really could be mistaken for the iPhone 5 at a glance.

However, similarities apart, this is a lovely handset. That aluminium construction lends the phone a near iPhone 5-equalling level of build quality that just feels great in the hand. Also helping immensely are the proportions of the phone. While the record-breaking 6.18mm slimness we could take or leave – though notably we didn’t find it so thin as to be unwieldy – the narrowness makes the phone sit nice and snug in the hand. In comparison the Galaxy S4 is nearly 5mm wider and 6mm taller – that may not sound like a lot but in the hand it makes quite a difference.

This size difference may well be somewhat down to the smaller screen that the P6 uses but in fact that just highlights another way in which this phone trumps the S4 for ergonomics. The smaller 4.7in screen combined with the smaller body makes it significantly easier to get to grips with.

Even better are the main buttons that are ranged down the right edge of the phone. Up top is the power button while below is the volume. Both are perfectly placed so as to fall easily under finger or thumb, have just the right level of click and are nicely machined from aluminium – we’re talking class-leading stuff here.

We’re also fans of the use of on-screen buttons for Home, Back and Multi-tasking. Yes, it means you loose some screen space in some scenarios but equally it means there’s a decent amount of space below the screen to rest your thumb and grip the phone, unlike on the Galaxy S4 in particular.

The good news continues with the addition of a microSD slot that allows for cheap and simple upgrading of the phone’s storage.

However, not all is rosy. For a start the battery is inaccessible without dismantling the phone. Then there’s the placement of the charging socket, which is on the top edge – ever heard of a phone dock Huawei? But the worst is where Huawei has placed the headphone socket: right at the bottom of the left edge. This means the headphone cable gets in the way in almost every conceivable situation that the phone finds itself in – in the hand, in the pocket, when gaming…

Huawei Ascend P6 Preview

Although the P6 lacks a 1080p screen, in use it doesn’t feel remotely lacking (indeed there’s arguably an advantage of a slightly lower resolution screen as it requires less power to run and needs less processing power). Its 720p LCD screen is still very sharp (it’s basically iPhone Retina matching) and uses the latest laminated screen manufacturing techniques such that the image appears right on the surface, rather than below the front glass. The result is superb viewing angles and bright colours. How it fares in darker lighting conditions when watching a video, we’ll have to wait and see.

As for the phone’s interface, it felt suitably speedy, thanks to its quad-core 1.5GHz chip (Huawei K3V2) and the use of Android 4.2.2. The look and feel is very different to stock Android as Huawei has gone to town customising it – and we had precious little time to really get to grips with it – but from what we could see it was largely cosmetic and all the key functions still work as any users of vanilla Android would expect.

Huawei was certainly keen to talk up the many funky features that its Emotion UI includes but five minutes at a press event is hardly time enough to do any of them justice.

Likewise the rear camera, which is an 8megapixel BSI model. With an F2.0 lens, it has a faster optic than both the iPhone 5 and Samsung Galaxy S4. While this may sound impressive, the HTC One had a equally fast lens and that phone’s camera has far from lived up to expectations.

Taking a few snaps with the P6, the camera seems nice and speedy in operation with a clean interface – and that extra thumb space really helps for when holding the phone in landscape orientation. When it comes to image quality, we’ll have to wait and see

All told, from what we’ve seen so far, the Huawei Ascend P6 is going to be a phone well worth considering if it really does come to market at around £300-£350. It’s in fact a shame there are a few slipups like the headphone socket placement as without those it could have enough going for it to take on the likes of the HTC One, iPhone 5 or Galaxy S4 right at the top of the smartphone league.

Huawei unveils Ascend P6, world’s slimmest smartphone

Huawei unveils Ascend P6, world's slimmest smartphone

The Huawei Ascend P6 will be available in white, black and pink!


Huawei has unveiled what it claims is the world’s slimmest smartphone, in the shape of the 6mm thick Huawei Ascend P6.

The P6 is the company’s new flagship phone with largely a specs list to match. Powered by a quad-core 1.5Ghz processor, it sports a 4.7in LCD screen with ‘in-cell’ technology, an 8megapixel rear camera, and a stylish, very iPhone 5-esque design.

Said design has, according to the Nick Woodley (Huawei UK design), been inspired by paper – that stuff which smartphones are largely replacing – with the company aiming for slimness and simplicity. At just 6.18mm thick and weighing 120g, it’s fair to say this is something the company has achieved.

However, similarities with the iPhone 5 are so strong that we wouldn’t be surprised to see Apple suing, just as it did with Samsung over that company’s Galaxy S line. Differentiating itself somewhat, the Ascend P6 will not just be available in black and white but pink too!

“The HUAWEI Ascend P6 is a star among smartphones with its industry-leading design, high-quality camera, and intuitive user interface, Huawei’s proprietary Emotion UI,” said Richard Yu, Chief Executive Officer, Huawei Consumer Business Group.

Other key features of the phone include a super-slim 2000mAh battery, which should be large enough to provide this phone with all-day battery life. However, the rear cover isn’t removable for quickly swapping the battery out.

Rather more serious omissions, though, come in the form of the screen, which is only 720p rather than 1080p, and the lack of 4G LTE. Although by no means crucial, their absence does put this phone a step behind most of its key competitors.

On the flip side, one advantage over many is the inclusion of a microSD slot for expanding the storage.

As for the camera, Huawei was keen to talk up its low light capabilities but there doesn’t seem to be any physical reason why it should be better than competitors. With an F2.0 lens and 8megapixel BSI sensor it relies on its software prcoessing to make the most of its images. One such feature is a quick ‘Beauty Level’ adjustment that smooths out skin tone for a more youthful look.

The phone’s software somewhat inevitably has an extensive set of customisations in the shape of Huawei’s Emotion UI. Features include the Automated Discontinuous Reception (ADRX) and Quick Power Control (QPC) which are said to improve battery life by 30%. Under the tweaks it’s running Android 4.2.2.

Chairman of TalkTalk and Carphone Warehouse, Charles Dunstone, took to the stage at the launch event to announce that the companies would be stocking the device. This marks the first time the companies have stocked any Huawei phones, with Dunstone talking up the fact that this phone marks the real coming of age of Huawei as a global brand, proclaiming “there’s a new competitor on the blocks”. Apple, HTC, Samsung – take note.

The Huawei Ascend P6 will be arriving worldwide in August, retailing for 449euros.

We’ll be back with our first impressions shortly.

Smash Lego atoms with a Large Hadron Collider model

ATLAS Lego mini-model

This ATLAS mini model is gathering votes.

Unfortunately, the Large Hadron Collider is too big to bring home and put on display in your living room. Scientist Sascha Mehlhase created a 4,500-piece Lego model of the collider back in 2011 at a cost of about $2,700. That was also too big for most people.

Now, he has created a smaller model of the ATLAS experiment, a particle physics experiment at the Large Hadron Collider, and put it up as a candidate for an official Lego kit.

The project is on Cuusoo, a site for Lego enthusiasts to share their models and attempt to gather 10,000 votes in order for Lego to consider making their creations as kits. Mehlhase’s ATLAS currently has 5,756 supporters, so it has definitely caught the eyes of Lego builders.

The new kit requires only 560 pieces, takes around an hour to construct, and has a materials costs of about $100, making it much more accessible than the big-daddy model.

Mehlhase is a postdoc at the Niels Bohr Institute in Copenhagen, Denmark, working on searches for stable massive particles in ATLAS. He also dedicates time to physics outreach projects aimed at getting kids excited about science. His discovery of a stable massive ATLAS Lego model has led him to the creation of a version that has a shot at ending up in the hands of Lego and physics enthusiasts around the world. If it works out, it will be a pretty impressive outreach accomplishment.

It’s heartening to know that adult scientists with access to some of the largest and most impressive scientific equipment ever created still want to play with little plastic blocks.

ATLAS 1:50 model

Mehlhase’s original model was much larger.

Curved OLED HDTV screens are a bad idea (for now)


(Credit:
Nic Healey/CNET Australia (right), Reuben Lee/CNET Asia (left))

Both Samsung and LG, two of the biggest players in the burgeoning world of Organic Light Emitting Diode televisions, have announced (or depending on where you live, are selling) curved OLED screens to go along with traditional “flat” OLED screens.

Curved screens have been used in theaters for decades, and more recently in some high-end home theaters too. In a TV though, it’s nothing more than a gimmick.

Here’s why.


(Credit:
LG)

Let me say up front that I am a huge fan of OLED. So much so that it pains me to write this article. OLED promises better picture quality than plasma, better energy efficiency than LED LCD, while being both thinner and lighter. You can sort of buy an LG model right now, and Samsung’s version seems perpetually on the horizon. We saw prototypes of 4K OLED TVs from Sony and Panasonic (they’ve teamed up), but nothing else so far. The issue is, and long has been, making them cheap enough to manufacture.

Curved screens have been found in many theaters, the most famous probably being the Cinerama Dome in Hollywood. It’s not a new idea, but the benefits still hold true today…in certain circumstances. With really large screens, one of the biggest advantages is being able to “focus” more light towards the audience. Another is reducing optical distortions when using certain projection lenses. There’s also a potential “naturalness” to an image that has every part equidistant to your eyeballs. But perhaps the most notable benefit is the ability to fill a massive percentage of a viewer’s field of view. Sitting in the right seat, one could have the image practically wrapped around them.

This is how Samsung describes the benefits of a curved screen: “the curved panel allows the distance between the user and TV screen to be the same from almost any angle.” And LG’s take: “With a gentle inward flex, the entire screen surface is equidistant from the viewer’s eyes, removing the problem of screen-edge visual distortion and detail loss.” So by their own definitions, one of the main reasons to have a curved screen is so every part is the same distance from the viewer’s eye.

Radius, radii, radiuses
The problem is not with the idea of curved screens, but a curved screen TV. To get the benefit of a wraparound image, or even the benefit of a more natural image that has every part equidistant from your eye, you need to be sitting in a pretty specific place. With a theater screen, that place is an area big enough in which a lot of people can sit. Sure, people off to the sides aren’t getting the best effect (if any), but the folks in the middle are. With a smaller curved screen, that sweet spot is a lot smaller.

LG)

Small TVs don’t have a very large sweet spot to being with. (I’m counting 55-inch TVs as small in this context, as they are small compared to theater screens.) Let’s take the curved aspect out for a moment. What’s the ideal seating area for a 55-inch, 1080p TV? That’s actually pretty easy. You should be sitting close enough so that you’re able to see all the resolution. Not so close that you can see individual pixels, but not so far that the TV could be 720p and it wouldn’t look any different. You also want it to fill your field of view enough so that it’s not like looking at a postage stamp from across the room.

I covered this from the other side in How big a TV should I buy? and we can use similar math here. THX recommends the TV fill 40 degrees of your field of view. So for a 55-inch TV, they’re recommending you sit 66 inches away. This is also about where people with 20/20 vision are seeing all the resolution possible with 1080p. SMPTE recommends 30 degrees, so they’re saying you should be 88 inches away.

So ideally, a curved OLED screen should have a curve whose radius is somewhere between 66 and 88 inches. Since most people still sit about 108 inches from their TVs, we could even accept this as an outside number.

Samsung)

Thankfully, Dennis Burger of HomeTechTell did some math and research on the curved part already. He figured that at a distance of 90 inches (well within our range), the TV would need a curve of about 3 inches between the center and the edges. The LG is not nearly this deep. According to LG, the OLED’s curve is 5 degrees, not the 7.5 needed for a 90-inch viewing distance. How different is that? Well, the LG’s “sweet spot,” based on its curve, is 134 inches away. Over 11 feet. Not only is this farther than most people sit from their TV, but it also means it might as well be 720p. In other words, in order to get every part of the screen equidistant from your eye, LG’s stated goal, you have to be sitting so far away that the screen will look tiny.

But this is all getting into the weeds. Even if a new curved OLED screen comes out, it effectively requires the owner to sit at a rather precise distance from the screen. Too close or too far, and the curve loses its major benefits. And let’s not forget, this is for one viewer. With several people on the couch, all the claimed benefits are lost.

Samsung)

Bottom line
Look, the fact that a “flat” screen TV can be curved at all is pretty amazing. But since OLED is barely off the ground (arguably, not off the ground at all), it’s disappointing to see finite resources going into something of little value beyond “hey, neato” which, also arguably, OLED inherently has already.

However, this won’t always be the case (we hope). The beauty of OLED is that, in theory, it’s scalable in size and resolution. So projection-screen-size, or even wall-size OLED screens are theoretically possible. In that case, a curved screen could be pretty awesome.

And while we’re dealing with this far off future, how about a flat, wall-size OLED screen that, at the touch of a button, curves in at the edges for movies? Flexible OLED screens. That’s a thing, too. Hurry up future times.

Experimenting with fireballs in space

Flames in space form actual fireballs.


(Credit:
Screenshot by Eric Mack/CNET)

Here on planet Earth we’re used to flames — whether from a candle or campfire — reaching upward to the sky with slender limbs hungry for oxygen and driven by rising hot air. But in space, sans our planet’s strong gravitational pull, flames are more likely to take the shape of eerie fireballs.

Within the flame of a regular candle wick, there’s quite a bit going on. As the video below released this week by NASA explains, molecules from the wick are being cracked apart and vaporized by the flame, then combined with oxygen to produce light, heat, carbon dioxide, and water, as well as soot.

In recent years we’ve become quite familiar with how flames can extend and expand quickly in their greedy quest for more fuel and oxygen; witness countless western wildfires of the past decade. But researchers aboard the International Space Station have observed that flames in microgravity behave much differently, staying in a small spherical shape and letting oxygen molecules come to them.

They also discovered something very strange while conducting experiments on how to put out fires in their environment. Small droplets of a fuel called heptane were set aflame inside a test chamber. The flames quickly went out, but surprisingly the droplets continued to burn without the presence of flames.

It could be that flames are actually present, but just too faint to see, something NASA refers to as “cool flames.”

Cool flames can burn at temperatures as low as 400 degrees Fahrenheit, but they behave very differently from the flames we’re used to. For starters, they don’t produce the carbon dioxide we’re used to getting from fires. Instead they give off carbon monoxide and formaldehyde. Fortunately, cool flames typically can’t exist on earth for more than a few fractions of a second, whereas they can persist on the International Space Station for up to a minute.

However, NASA says these insights could have practical implications on our planet, such as better fuel efficiency.

So get ready for the next generation of vehicles — new, improved, and with more space fireballs! Watch the video below for a more eloquent explanation of the science and let us know what potential you see in formaldehyde-expelling balls of fire in the comments.

Man proposes via language-learning app Duolingo

We’ve seen some pretty creative marriage proposals, but we never would have thought of proposing via a language-learning app. Flavio Esposito, on the other hand, seems to like thinking outside the down-on-one-knee box.

The Italian man’s American girlfriend was using Duolingo to learn Italian, so he got in touch with the Duolingo team to come up with a surprise.

“She’s learning my own language, and she enjoys it so much that I’m wondering if I could ask you to set up an exercise for her that would lead to the big question: ‘Will you marry Flavio Esposito?’” he wrote.

The team, unable to resist either the challenge or the romance, set about writing some translation exercises for Kate to be dropped into her learning program.

“Lu ti ama,” ran the first one: “He loves you.” “Lu ti adora:” “he adores you.” “Voi due parlate a telefono tutte le sere:” “the two of you talk on the phone every evening.”

Then the big question:

Who could say no? Certainly not Kate.

We hope the happy couple lives blissfully and bilingually ever after.

Flying bicycle with built-in tent cruises at 4,000 feet up

Paravelo flying bike

The Paravelo looks ready for launch.


(Credit:
XploreAir)

First, flying food became a trend. Now, the hot new flying creations are flying bicycles. The latest entry in the wheeled-air-machine category comes from British company XploreAir. It’s a bicycle, flying machine, and camping tent all built into one device.

The Paravelo can be taken apart and used as just a bike, or it can docked to its trailer with a flexible wing and biofuel-powered fan. Up in the air, it can go at speeds up to 25 mph for up to 3 hours and reach heights up to 4,000 feet up.

The bike itself is fairly lightweight, though the trailer with the fan adds quite a bit of size to the whole contraption. It all folds down for storage. XploreAir says the purchase and operating costs of the Paravelo will be similar to having a small family
car.

XploreAir is currently raising funds on Kickstarter to further develop the project. The biggest problem here is that you can’t actually get one of these flying bikes for a pledge.

The best you can hope for is to plop down $7,800 and get a non-flying replica of the bike, along with the option to buy one of the first five Paravelos to come off the production line. For that price, I would hope for at least a hop, skip, and a jump. The Paravelo won’t come cheap, but that’s not surprising.

If the Paravelo gets off the ground, it could open an interesting new chapter in personal exploration. It’s more adventurous than just hopping in your car. What is it with our desire to take earth-bound things and make them fly through the air, preferably with people on board? I guess we’re still envious of birds.

‘Wizard of Oz’ Lego re-creation has rotating tornado

Lego Wizard of Oz

The Emerald City is part of a Wizard of Oz display built by 12 members for Brickworld 2013.

We’ve seen plenty of crazy Lego re-creations over the years, from landmark architecture to vintage computers, but we can’t help but be impressed when an entire movie is redone in bricks.

That would be 1939 classic “The Wizard of Oz,” which a team of 12 Lego builders has turned into a marvelous 3D plastic diorama that includes just about every scene in the film, including a rotating tornado.

The collaborators from VirtuaLUG recently showed off the result of their teamwork at Brickworld 2013 Chicago, a display of spectacular Lego builds.

VirtuaLUG has done displays including portrayals of “Alice in Wonderland” and “The Lord of the Rings.” For its “Wizard of Oz” set, the 12 builders in three different countries worked on their components separately and then assembled them in Chicago.

The display, at least 10 feet long, begins with a sepia-tone re-creation of Kansas, complete with a spinning tornado carrying Dorothy’s house off to Oz.

It then turns into a brightly colored array of bricks to simulate Munchkinland and the Yellow Brick Road, which leads away to show minifigs of Dorothy meeting the Scarecrow, the Tin Man, and the Cowardly Lion.

The road leads through the poppy fields to the Emerald City, an eye-popping build of the green metropolis.

The display continues into the dark forest, which lights up with ultraviolet lights for an eerie glow, to the witch’s castle, which has a detachment of Winkie guards on the bridge. It concludes back in Emerald City as Oz’s balloon is about to launch.

Check out Beyond the Brick’s walk-through video of The Wizard of Oz display, which was named best collaboration at Brickworld, below.

Are you up for a challenge? How about a Grand Challenge? NASA on Tuesday issued a Grand Challenge aimed at locating all asteroid threats to Earth and figuring out what to do about them.

It seems the asteroid threat has really picked up steam lately. We’ve had some close fly-bys. Some scientists have suggested nuking asteroids if they get too near. NASA has an initiative to lasso an asteroid for closer study. It’s been asteroid fever around the planet lately.

You don’t have to have a string of initials behind your name or a place on the roster of a science agency to participate in this challenge. It’s open to all, including citizen scientists.

“NASA already is working to find asteroids that might be a threat to our planet, and while we have found 95 percent of the large asteroids near the Earth’s orbit, we need to find all those that might be a threat to Earth,” said NASA Deputy Administrator Lori Garver in an announcement.

Along with the challenge, NASA issued a request for information for ideas on locating, redirecting, and exploring asteroids. If you or your organization has been spending some of brain power on the asteroid problem, then now is the time to share your thoughts.

Snowden answers reader questions

Washington (CNN) — A series of blog posts on Monday purportedly by Edward Snowden said he leaked classified details about U.S. surveillance programs because President Barack Obama worsened “abusive” practices instead of curtailing them as he promised as a candidate.

In 90 minutes of live online chatting, the person identified as Snowden by Britain’s Guardian newspaper and website insisted that U.S. authorities have access to phone calls, e-mails and other communications far beyond constitutional bounds.

While he said legal restrictions can be easily skirted by analysts at the National Security Agency, FBI and CIA, Snowden stopped short of accusing authorities of violating specific laws. Instead, he said toothless regulations and policies were to blame for what he called “suspicionless surveillance,” and he warned that policies can be changed to allow further abuses.

“This disclosure provides Obama an opportunity to appeal for a return to sanity, constitutional policy, and the rule of law rather than men,” he posted. “He still has plenty of time to go down in history as the president who looked into the abyss and stepped back, rather than leaping forward into it.”

Obama bristles at suggestion he’s shifted on snooping


Obama: NSA programs are transparent


Snowden: Hong Kong easiest answer


Snowden: The NSA has your content


Releasing NSA leaks: A public service?

Asked Monday if the NSA was following the online chat, the agency’s press office had no immediate comment.

Obama, top legislators and national security officials defend the surveillance programs as necessary to combat terrorism, arguing that some privacy must be sacrificed in a balanced approach.

They say the law allows collection of metadata, such as the time and numbers of phone calls, and that a special federal court must approve accessing the content — listening to the call itself.

In the blog posts on Monday, the writer identified as Snowden contended the government’s overbroad collection of information violated rights of innocent Americans who have no links to suspicious activity.

Referring to a program that permits broader access to foreign communications than is allowed for domestic monitoring, the writer said authorities sidestep regulations. For example, a phone call from overseas can mean automatic inclusion of a U.S. number in the record-keeping, according to the writer.

“The reality is that … Americans’ communications are collected and viewed on a daily basis on the certification of an analyst rather than a warrant,” one Snowden post said. “They excuse this as ‘incidental’ collection, but at the end of the day, someone at NSA still has the content of your communications.”

Another post warned that restrictions against unauthorized access to the content of communications — such as listening to phone calls or reading e-mails — were based on policy rather than technology and therefore “can change at any time.”

CNN poll: Obama numbers plunge into generation gap

Snowden said he leaked details of the surveillance programs because Obama campaigned for the presidency on a platform of ending abuses.

However, Obama “closed the door on investigating systemic violations of law, deepened and expanded several abusive programs, and refused to spend the political capital to end the kind of human rights violations like we see in Guantanamo, where men still sit without charge,” a blog post said.

Snowden also said that he had to get out of the United States before the leaks were published by the Guardian and Washington Post to avoid being targeted by the government.


Columnist: NSA leak sparked debates


Spying on G-20 delegates?


Rep.: NSA isn’t listening to your calls


Hong Kong rallies to support NSA leaker

The U.S. government “predictably destroyed any possibility of a fair trial at home” by “openly declaring me guilty of treason,” Snowden said.

Snowden, who is believed to be in Hong Kong, also wrote that the truth about surveillance programs he disclosed will come out, and “the U.S. government is not going to be able to cover this up by jailing or murdering me.”

Details on NSA-thwarted plots coming, lawmaker says

The blog post rejected accusations that he had or might provide classified information to China, saying he only leaked to journalists and calling such a charge a smear tactic intended to turn public opinion against his effort to provide Americans with full information about how their government monitors them.

A CNN/ORC International poll released Monday showed 54% of respondents didn’t approve of Snowden’s admitted actions, while 44% backed the leaks.

Snowden’s father told Fox News that he hoped and prayed his son “will not release any secrets that could constitute treason.”

The father, Lon Snowden, also said he wanted his son to return to the United States “and face this,” adding “I love my son.”

Snowden, 29, worked for the NSA through a private contractor firm until May, when he decamped to Hong Kong. He went public earlier this month as the source of articles by the newspapers, saying the agency’s efforts pose “an existential threat to democracy.”

The revelations about the NSA’s collection of millions of records from U.S. telecommunications and technology firms have led to a furious debate within the United States about the scale and scope of surveillance programs that date from the days after the 2001 al Qaeda attacks on New York and Washington.

Opinion: Did NSA snooping stop ‘dozens’ of terrorist attacks?

Defenders say the programs — approved by Congress after a warrantless surveillance effort under the Bush administration was revealed in 2005 — have protected American lives by helping agents break up terrorism plots. And they argue that the program is under close oversight by all three branches of government, including the congressional intelligence committees and a court set up under the Foreign Intelligence Surveillance Act that hears cases in secret.

But Glenn Greenwald, the Guardian columnist who broke Snowden’s story and moderated the chat, said the safeguards placed on the program is “a very symbolic and empty oversight that really ought not to give the assurances to anybody that these powers aren’t being abused.”

“They go once every six months to the FISA court,” he said. “The FISA court rubber-stamps these vague guidelines that the NSA says they’re using to make sure they’re complying with the law. And once that happens, the NSA can force telecoms and Internet companies to give them whatever they demand under the guise that the FISA court has blessed their guidelines.”

Bigger threat: Snowden or NSA?

Critics call the programs an unconstitutional overreach of authority under the Patriot Act, the law that authorized increased government surveillance in the aftermath of the 9/11 attacks.

In a new development, the Guardian reported Sunday that Britain’s electronic intelligence agency monitored delegates’ phones and tried to capture their passwords during an economic summit held there in 2009.

Targets included British allies such as Turkey and South Africa, the newspaper reported. The Guardian cited documents provided by Snowden.

According to the newspaper, the documents show that the British “signals intelligence” agency GCHQ used “ground-breaking intelligence capabilities” to intercept calls made by members of the G-20 conference delegations at meetings in London.

Facebook, Microsoft disclose information on user data requests

Analysts received round-the-clock summaries of calls that were being made, and GCHQ set up Internet cafes for delegates in hopes of intercepting e-mails and capturing keystrokes, the Guardian reported.

One briefing slide explained the intercepts would give intelligence agencies the ability to read delegates’ e-mails “before/as they do,” providing “sustained intelligence options against them even after (the) conference has finished.”

GCHQ is Britain’s equivalent of the secretive NSA in the United States.

The Guardian reported that the NSA had attempted to eavesdrop on then-Russian President Dmitry Medvedev during the conference as his phone calls passed through satellite links to Moscow and briefed its British counterparts on the effects.

The latest report was published on the eve of a smaller economic summit hosted by the British government — the Group of Eight gathering in Northern Ireland.

Shawn Turner, a spokesman for the U.S. Office of the Director of National Intelligence, said Sunday he was aware of the Guardian’s latest report but declined to comment on it.

“What we should be focused on is how irresponsible and egregious these recent leaks are,” he told CNN. “It’s impossible to know exactly how much damage is being done by these disclosures, but they will have an effect on our counterterrorism efforts.”

Retired Gen. Michael Hayden, a former NSA director, said on CNN’s “Fareed Zakaria GPS” that what the agency collects are “essentially billing records” that detail the time, duration and phone numbers involved in a call.

The records are added to a database that agents can query in cases involving a terror investigation overseas, and agents can’t eavesdrop on Americans’ calls without an order from a secret court that handles intelligence matters, he said.

If a phone number related to an investigation has links to a domestic phone number, “We’ve got to go back to the court,” he said.

However, critics such as Sen. Mark Udall, a member of the Senate Intelligence Committee, had raised questions about the scale of the program even before Snowden’s leak.

Udall said on NBC’s “Meet the Press” on Sunday that he doesn’t believe the program is making Americans any safer, “and I think it’s ultimately, perhaps, a violation of the Fourth Amendment.”

“I think we owe it to the American people to have a fulsome debate in the open about the extent of these programs,” said Udall, a Colorado Democrat. “You have a law that’s been interpreted secretly by a secret court that then issues secret orders to generate a secret program. I just don’t think this is an American approach to a world in which we have great threats.”

Obama does not feel that he has violated the privacy of any American, his chief of staff, Denis McDonough, said on the CBS program “Face the Nation.”

McDonough said the president will be discussing the need to “find the right balance, especially in this new situation where we find ourselves with all of us reliant on Internet, on e-mail, on texting.”
