SEAL Killed in Rescue Mission Identified













The Pentagon has identified Petty Officer 1st Class Nicolas Checque as the Navy SEAL who died of injuries sustained in the successful rescue of an American doctor from the Taliban over the weekend.


Checque, who hailed from Monroeville, Pa., died of "combat related injuries," according to a Pentagon release. Though the release only said Checque was assigned to "an East Coast-based Naval Special Warfare unit," ABC News previously reported the fallen servicemember was a part of the Navy's elite SEAL Team 6, the same unit that killed Osama bin Laden.


Checque, 28, sustained his mortal injuries while on a nighttime mission Saturday to free Dr. Dilip Joseph, an American doctor who worked for an non-governmental organization based in Kabul. Joseph was kidnapped by the Taliban earlier this month and American officials believed he was in imminent danger.

Joseph's family released a statement thanking the U.S. government and military for the operation and offering their condolences to Checque's family.


"We could not be more grateful for that soldier's heroism and for the bravery of all involved in the mission to bring Dilip home," the statement said.


Before Checque was identified publicly, Defense Secretary Leon Panetta said Sunday he was "deeply saddened" to learn one of the servicemen had died.


"The special operators who conducted this raid knew they were putting their lives on the line to free a fellow American from the enemy's grip. They put the safety of another American ahead of their own, as so many of our brave warriors do every day and every night. In this fallen hero, and all of our special operators, Americans see the highest ideals of citizenship, sacrifice and service upheld. The torch of freedom burns brighter because of them," Panetta said.


President Obama also praised the Special Operations force for their bravery.


"Yesterday, our special operators in Afghanistan rescued an American citizen in a mission that was characteristic of the extraordinary courage, skill and patriotism that our troops show every day," he said Sunday.

Why the world is arguing over who runs the internet






















The ethos of freedom from control that underpins the web is facing its first serious test, says Wendy M. Grossman






















WHO runs the internet? For the past 30 years, pretty much no one. Some governments might call this a bug, but to the engineers who designed the protocols, standards, naming and numbering systems of the internet, it's a feature.












The goal was to build a network that could withstand damage and would enable the sharing of information. In that, they clearly succeeded - hence the oft-repeated line from John Gilmore, founder of digital rights group Electronic Frontier Foundation: "The internet interprets censorship as damage and routes around it." These pioneers also created a robust platform on which a guy in a dorm room could build a business that serves a billion people.












But perhaps not for much longer. This week, 2000 people have gathered for the World Conference on International Telecommunications (WCIT) in Dubai in the United Arab Emirates to discuss, in part, whether they should be in charge.












The stated goal of the Dubai meeting is to update the obscure International Telecommunications Regulations (ITRs), last revised in 1988. These relate to the way international telecom providers operate. In charge of this process is the International Telecommunications Union (ITU), an agency set up in 1865 with the advent of the telegraph. Its $200 million annual budget is mainly funded by membership fees from 193 countries and about 700 companies. Civil society groups are only represented if their governments choose to include them in their delegations. Some do, some don't. This is part of the controversy: the WCIT is effectively a closed shop.












Vinton Cerf, Google's chief internet evangelist and co-inventor of the TCP/IP internet protocols, wrote in May that decisions in Dubai "have the potential to put government handcuffs on the net".












The need to update the ITRs isn't surprising. Consider what has happened since 1988: the internet, Wi-Fi, broadband, successive generations of mobile telephony, international data centres, cloud computing. In 1988, there were a handful of telephone companies - now there are thousands of relevant providers.












Controversy surrounding the WCIT gathering has been building for months. In May, 30 digital and human rights organisations from all over the world wrote to the ITU with three demands: first, that it publicly release all preparatory documents and proposals; second, that it open the process to civil society; and third that it ask member states to solicit input from all interested groups at national level. In June, two academics at George Mason University in Virginia - Jerry Brito and Eli Dourado - set up the WCITLeaks site, soliciting copies of the WCIT documents and posting those they received. There were still gaps in late November when .nxt, a consultancy firm and ITU member, broke ranks and posted the lot on its own site.












The issue entered the mainstream when Greenpeace and the International Trade Union Confederation (ITUC) launched the Stop the Net Grab campaign, demanding that the WCIT be opened up to outsiders. At the launch of the campaign on 12 November, Sharan Burrow, general secretary of the ITUC, pledged to fight for as long it took to ensure an open debate on whether regulation was necessary. "We will stay the distance," she said.












This marks the first time that such large, experienced, international campaigners, whose primary work has nothing to do with the internet, have sought to protect its freedoms. This shows how fundamental a technology the internet has become.












A week later, the European parliament passed a resolution stating that the ITU was "not the appropriate body to assert regulatory authority over either internet governance or internet traffic flows", opposing any efforts to extend the ITU's scope and insisting that its human rights principles took precedence. The US has always argued against regulation.












Efforts by ITU secretary general Hamadoun Touré to spread calm have largely failed. In October, he argued that extending the internet to the two-thirds of the world currently without access required the UN's leadership. Elsewhere, he has repeatedly claimed that the more radical proposals on the table in Dubai would not be passed because they would require consensus.












These proposals raise two key fears for digital rights campaigners. The first concerns censorship and surveillance: some nations, such as Russia, favour regulation as a way to control or monitor content transiting their networks.












The second is financial. Traditional international calls attract settlement fees, which are paid by the operator in the originating country to the operator in the terminating country for completing the call. On the internet, everyone simply pays for their part of the network, and ISPs do not charge to carry each other's traffic. These arrangements underpin network neutrality, the principle that all packets are delivered equally on a "best efforts" basis. Regulation to bring in settlement costs would end today's free-for-all, in which anyone may set up a site without permission. Small wonder that Google is one of the most vocal anti-WCIT campaigners.












How worried should we be? Well, the ITU cannot enforce its decisions, but, as was pointed out at the Stop the Net Grab launch, the system is so thoroughly interconnected that there is plenty of scope for damage if a few countries decide to adopt any new regulatory measures.












This is why so many people want to be represented in a dull, lengthy process run by an organisation that may be outdated to revise regulations that can be safely ignored. If you're not in the room you can't stop the bad stuff.

ASEAN chair urges NKorea to call off rocket launch






PHNOM PENH: Cambodian Prime Minister and ASEAN chairman Hun Sen urged North Korea Monday to scrap a planned rocket launch, saying it would bring "fear and tension" to the region.

Pyongyang on Monday pushed back the window for the controversial planned launch by a week to December 29, but stressed it was pressing ahead with the mission in the face of international condemnation.

"In the name of the ASEAN chair, I appeal to North Korea to postpone the launch forever," Hun Sen said in a speech on national radio. "The launch will bring no benefits but only fear in the region and tension."

The premier said he had "the right to speak out" after foreign ministers of the 10-member Association of Southeast Asian Nations failed over the past week to reach agreement on a draft statement about the launch.

Hun Sen said his Foreign Minister Hor Namhong had been in talks with ASEAN counterparts but they could not reach "a consensus" on Cambodia's draft. He did not elaborate.

Pyongyang extended the December 10-22 window for the launch by a week due to a "technical deficiency", the Korean Committee of Space Technology said in a statement carried by the official Korean Central News Agency.

North Korea says the rocket launch is a peaceful mission aimed at putting a satellite in orbit.

The United States and its allies view it as a disguised ballistic missile test banned under UN resolutions prompted by the North's nuclear tests in 2006 and 2009.

ASEAN comprises Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam.

Five lies your TV salesperson will tell you



Using the time-honored tactics of obfuscation, misdirection, and a little bit of fear, the people who try to sell you TVs can hit you with some heavy-duty lies.


Now this isn't to say that all TV sales people are bad, nor that any necessarily do this out of malice (there's plenty of misinformation out there confused as truth). But when it's your dollar on the line, being prepared with some facts can only be a good thing.



For a primer on all the jargon, check out "TV tech explainer: Every HDTV technology decoded."


'This TV has a million-to-one contrast ratio.'
No, it doesn't. Every TV manufacturer lies about contrast ratio. Not a single one is remotely accurate. So it's impossible to prescribe an exact number to any TV given only the manufacturers data. The fact is, plasmas have better native contrast ratios than LCDs (LED or otherwise). There are three local-dimming LED LCDs on the market this year (Elite by Sharp, Sony HX950, and LG LM9600), and they're all extremely expensive. These offer similar contrast ratios than the best plasmas, though not exactly. For more info, check out "Contrast ratio (or how every TV manufacturer lies to you)."


'This TV has better sound.'
You know what, let's say they're right. Let's say TV A has better sound than TV B. The fact is, no TV sounds good. So all they're really saying is, "This TV sounds less bad than this other TV."


The thinness that we all love in flat-panel TVs means the speaker drivers by their very nature have to be very small. Small drivers can't do much to create sound waves.


The wiser salespeople will direct you towards a sound bar or other home audio system. This is definitely where you should spend a few dollars. Pretty much every sound bar will sound better than the TV speakers, and the better sound bars actually sound pretty good.


Check out CNET's page on the best home audio and best sound bars.



'TVs break all the time. You need an extended warranty.'
Another example of this is "I see TVs come in for repair all the time." From a rhetorical standpoint, this is a rather brilliant argument. This person works at the store. They see lots of TVs coming in for repair. So as an "authority," this seems a valid point.


Except, it isn't.


What the salesperson isn't seeing, is all the TVs that don't come in for repair. Which is most of them. Flat-panel TVs are very reliable, so an extended warranty is a largely a waste of money.


'LED TVs have the best picture quality.'
Nope. First of all, there's no such thing as an "LED TV." Every
LED TV is just a standard LCD TV that uses LEDs to create light instead of the "old-fashioned" cold-cathode fluorescent lamps (CCFL). LCDs have their positives, like light output and lower energy consumption, but when it comes to a direct picture quality comparison, plasmas have better black levels, better contrast ratios, and better viewing angles (for those not sitting directly in front of the TV). For example, four of the five TVs CNET picked for best picture quality are plasmas (the one LED LCD is also the most expensive TV you can buy per-screen-inch).


There's more to it than that, as I lay out in "Why LED does not mean a better picture" and "LED LCD vs. plasma vs. LCD."


'If you want the best picture and sound, you need the best HDMI cable.'
This is the one that annoys me the most, and I've written four articles about it for CNET alone. This is the one that eliminates any guilt I have impugning the good name of some hard-working salespeople. There is no picture or sound quality difference between any HDMI cable. None. At all. So if you spend $3 or $300, the image and sound will be 100 percent exactly the same.


I could talk about this forever, and indeed I have. Check out "Why all HDMI cables are the same,"
"Why all HDMI cables are the same, Part 2,"
"Still more reasons why all HDMI cable are the same," and the "HDMI cable buying guide."


Bottom line



It is difficult to get a man to understand something, when his salary depends upon his not understanding it! -- Upton Sinclair



A commenter on one of the HDMI articles posted the above quote, and it's perfect. But look, be polite. Don't waste someone's time. This goes for both sides. They're just trying to make a living, you're just trying to keep as much of your living as possible. When I sold electronics at Circuit City, I was given all sorts of information, presented as truth, to tell customers. Much of which I know now to be false, or at least "truth adjacent." But as an 18-year-old, long haired (yep, believe it), wannabe guitar god, I didn't know any better. So give the poor guy or gal the benefit of the doubt that they're not knowingly lying to you.



Except for that HDMI cable stuff; man that bugs me.



How about you? Been told any doozys?




Got a question for Geoff? Send him an e-mail! If it's witty, amusing, and/or a good question, you may just see it in a post just like this one. No, he won't tell you which TV to buy. Yes, he'll probably truncate and/or clean up your e-mail. You can also send him a message on Twitter: @TechWriterGeoff.

Plants Grow Fine Without Gravity


When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Fiscal Cliff Talks: Boehner, Obama Meet Face-to-Face













For the first time in more than three weeks, President Obama and House Speaker John Boehner met face-to-face today at the White House to talk about avoiding the fiscal cliff.


White House Principal Deputy Press Secretary Josh Earnest would offer no details saying only, "The lines of communication remain open."


Erskine Bowles, the co-creator of a debt reducing plan, who was pessimistic a couple weeks ago, said he likes what he's hearing.


"Any time you have two guys in there tangoing, you have a chance to get it done," Bowles said on CBS's "Face the Nation."


The White House afternoon talks, conducted without cameras or any announcement until they were over, came as some Republicans were showing more flexibility about approving higher tax rates for the wealthy, one of the president's demands to keep the country from the so-called fiscal cliff -- a mixture of across-the-board tax increases and spending cuts that many economists say would send the country back into recession.

Fiscal Cliff Battle: President Obama vs. Speaker John Boehner Watch Video





"Let's face it. He does have the upper hand on taxes. You have to pass something to keep it from happening," Sen. Bob Corker of Tennessee said on "FOX News Sunday."


This comes after the White House moderated one of its demands about tax rate increases for the wealthy.


The administration was demanding the rate return to its former level of 39.6 percent on income above $250,000. The so-called Bush tax cut set that rate at 35 percent. But Friday, Vice President Joe Biden signaled that rate could be negotiable, somewhere between the two.


"So will I accept a tax increase as a part of a deal to actually solve our problems? Yes," said Oklahoma Republican Tom Coburn on ABC's "This Week."


The problems the senator was referring to are the country's entitlement programs. And there was some progress on that front, too.


A leading Democrat said means testing for Medicare recipients could be a way to cut costs to the government health insurance program. Those who make more money would be required to pay more for Medicare.


"I do believe there should be means testing, and those of us with higher income and retirement should pay more. That could be part of the solution," Sen. Dick Durbin of Illinois said on NBC's "Meet the Press."


But Durbin said he would not favor raising the eligibility age from 65 years old to 67 years old, as many Republicans have suggested.


The White House and the speaker's office released the exact same statement about the negotiating session. Some will see that as a sign of progress, that neither side is talking about what was said behind closed doors.

Sweet scent doubles as repellent for flower eaters









































A FLOWER'S delicate fragrance is not just a come-hither call to insect pollinators. Some scent molecules act as deterrents to drive away blossom-munching predators.












Ian Baldwin of the Max Planck Institute for Chemical Ecology in Jena, Germany, and colleagues genetically modified petunia plants to silence genes responsible for producing specific scent molecules. They then tested how these altered plants fared in the presence of flower-eating beetles and crickets.












When the production of the scent molecules benzyl benzoate or isoeugenol was blocked, the insects ate several times more of the flowers than they did when they were presented with petunias that hadn't been genetically altered.












To confirm whether it was indeed the scent putting off the insects, the researchers placed vials of isoeugenol or benzyl benzoate next to the genetically modified petunias. Sure enough, the presence of the chemical was enough to deter the insects (Ecology Letters, doi.org/jv7).












The study is the first to demonstrate that scent chemicals are used by flowers to discourage and attract insects. The complex scents of other flower species probably also include repellent as well as attractive chemical signals, says team member Thomas Colquhoun of the University of Florida in Gainsville.

N Korea stops rocket launch preparations: report






SEOUL: North Korea has stopped all preparations for a rocket launch at a site in the country's northwest, a South Korean official told Yonhap News Agency on Sunday.

The report came after North Korea said earlier on Sunday it may delay the much-criticised launch, that was originally scheduled for as early as this week, with analysts saying the postponement could be due to technical problems.

Scientists were "now seriously examining the issue of readjusting the launching time of the satellite for some reasons", the Korean Committee of Space Technology said in a statement carried by state media.

Analysts said technical problems or snow, rather than overseas political pressure, are likely to be behind the delay in what the North calls a satellite launch, originally scheduled for between December 10 and 22.

The United States, and allies South Korea and Japan, say Pyongyang was planning a disguised ballistic missile test that violates UN resolutions triggered by its two nuclear tests in 2006 and 2009.

Did Twitter's founder reveal its would-be Instagram killer?



Photos tweeted today by Twitter co-founder Jack Dorsey may have been generated using the service's rumored photo filters.



(Credit:
Jack Dorsey)



Twitter co-founder Jack Dorsey may have dropped the first public proof that Twitter is getting ready to release its own photo filtering feature, a tool it hopes could help in its increasingly tense battle with Instagram.


A report published today by All Things D suggested that informed sources have said that Twitter plans to launch its photo filtering tool before year's end. A series of black-and-white photos tweeted by Dorsey today appear to have been created using Twitter's own photo hosting service, pic.twitter.com. That would mean that Dorsey, who has largely relinquished his operational role at Twitter, and who is the founder and CEO of mobile payments startup Square, may well have been using the rumored new tool.


As All Things D wrote:


Twitter is making a big push to release a series of photo filters to be used inside the official Twitter app before the end of the year, according to sources familiar with the matter.


The goal is to release the camera filters in an application update in time for the holiday season, these sources say. The new version of the app is currently in testing, which may be why we're seeing Twitter chairman Jack Dorsey post so many black-and-white filtered photos of his Square employees (not to mention the wing of his plane at takeoff, posted just this Saturday morning).



The New York Times first reported the rumors of Twitter's photo-filtering initiative last month.


If the All Things D and New York Times reports are correct, it would be the latest salvo in the escalating war between Twitter and Instagram. Earlier this week, Instagram deactivated Twitter Card integration, a step that resulted in Instagram photos showing up poorly cropped in tweets. The goal, Instagram CEO Kevin Systrom said, was to get more of his company's users utilizing the service on the Web. But it was also clear Instagram wants to wean its users off of Twitter.


Twitter did not respond to a request for comment this evening.


It appears that executives at Twitter are eager to push out major new features by year's end. In several speeches, CEO Dick Costolo has said that he is intent on making users' entire tweet histories available by the end of the year. And if the All Things D report is true, the company also wants its photo filtering tools in users' hands by New Year's. "Why push it out before the new year? Perhaps Twitter wants a cut of the inevitable jump in photos we'll see as everyone goes home for the holidays," All Things D wrote. "Instagram, for instance, saw more than 200 Thanksgiving-related photos posted to its service every second on Thanksgiving Day alone, and ten million Thanksgiving photos posted overall that day."
