It's a little late for Christmas presents, but if you throw a little time-machine action in the mix, this might be the perfect gift for the hacker kid in your life: Circuit Playground plushies.




The plushies are the newest product from Adafruit Industries -- one of the world's leaders in the open-source hardware world, and the makers of a wide range of products for hackers young and old. Led by Entrepreneur magazine's entrepreneur of the year Limor Fried, Adafruit has a long history of promoting the do-it-yourself movement, and giving those who play and work in it the tools they need. They are also big culture hackers, having offered a bounty for the first person to hack Microsoft's Kinect, produced a series of hacker scout badges, and come up with a concept for a Lego set for geek girls. The plushies are tied to Adafruit's Circuit Playground app.


As Adafruit wrote about the new plushies on its Web site, "We know it's hard to figure exactly what will spark a young mind on to the journey towards science, technology, engineering, art, math and more -- we wish we had these when were young."


There are six plushies -- Cappy the Capacitor, Hans the 555 Timer chip, MHO the Resistor, Connie the Transistor, Ruby the Red LED, and Gus the Green LED."

Silent Skype calls can hide secret messages









































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaś and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

Lenovo makes computer play a family affair






SAN FRANCISCO: Lenovo on Sunday unveiled a home tabletop touch-screen computer aimed at turning typically solitary online activities into family affairs.

The Chinese computer colossus proclaimed the arrival of the "interpersonal PC" with the debut of the IdeaCentre Horizon Table in Las Vegas, where the Consumer Electronics Show gadget gala is set to start.

"It's definitely a new category; the world's first home table personal computer," Lenovo director of global marketing Dee Kumar said while giving AFP an early glimpse at the creation in San Francisco.

"This can be a full-power 27-inch PC, but at the same time we want families using this device," she said.

The "multi-user, multi-touch, multi-mode" table computer with a starting price of $1,699 can be used by several people simultaneously for communal activities such as games or for individual endeavours such as updating Facebook.

"We want to take social to the next level," Kumar added. "Smartphones and tablets provide one-to-one interaction, but it is great for a family to come back home and use this device to consume content."

Lenovo worked with videogame industry stalwarts including Ubisoft and Electronic Arts to tailor titles for group play on Horizon table computers.

"These games are simple mechanics-wise but really fun to play in a social space," Pixel, a member of an Ubisoft-backed group of girl gamers known as the Frag Dolls, said as she killed virtual zombies and raced cars on Horizon.

Lenovo promised to showcase a slew of Horizon games and applications at CES, which begins Tuesday.

Horizon is powered by Microsoft Windows 8 software designed with touch-screen controls in mind and recognizes commands from as many as 10 fingers at a time.

"Windows 8 definitely opened the doors to social with 10-finger touch," Kumar said. "You are seeing touch interfaces on bigger devices, and this is kind of the next extension."

Horizon weighs about 18 pounds and is built with a hinged stand in the back so it can be propped upright to serve as a television or desktop computer screen.

Wheeled stands and joysticks are among accessories sold separately. Lenovo said that Horizon table computers would hit the market by the middle of this year.

"Horizon makes personal computing interpersonal computing with shared, collaborative experiences among several people," said Lenovo product group president Peter Hortensius.

Lenovo has been striving to become the world's top computer maker and has made strides with a "protect and attack" strategy when it comes to market share.

Analysts have described Lenovo as a success story due to its tactic of fielding a diverse line-up of products in a global computer industry being roiled by the rise of tablets and smartphones.

Gartner Research in October released preliminary figures indicating Lenovo may have taken Hewlett-Packard's crown as top computer maker in the third quarter of last year.

IDC figures, however, showed that HP retained a tenuous hold on the throne.

Still, "our protect-and-attack strategy is clearly working," Kumar said, "We go after high growth areas and protect core business."

Bolting your food? Put on the brakes with HapiFork



Inventor Jacques Lepine with the HapiFork, which buzzes when you bolt food.

Tim Hornyak/CNET)



LAS VEGAS--Does your mom's lasagna taste better if you savor each bite as if it were your last?


It might or might not, but if you slow down when eating, chances are you'll eat less. That's the idea behind HapiFork, shown off at 2013
CES Unveiled.


The fork vibrates if you take a bite less than 10 seconds after the last mouthful. That will teach you to slow down, enjoy each morsel, and allow your brain to rein in your appetite.


After all, it takes about 20 minutes for your brain to start sending out signals that you're full.


"Your hormones are offset when you eat too quickly," says inventor Jacques Lepine of France-based Hapilabs. "It's bad for satiation and bad for the transformation of nutrients."




Lepine, an engineer by trade, was always told he ate too quickly when he was young. He once thought he was having a heart attack and rushed to the hospital, only to be told that it was gastric reflux.


His doctor told him to slow down when eating, and over the next seven years he developed a tool to help pace himself.


The HapiFork, and its companion the HapiSpoon, have a simple timer and vibration mechanism in their removable handles. They're also Micro USB-chargeable.


They haven't proven effective at helping people lose weight yet, says Lepine, but they're only launching within the next two months. They should be priced around $99.


What's it like waiting 10 seconds between bites? It takes patience, Lepine says, but he doesn't wolf down his dinner anymore.

Hagel to Be Obama's Defense Secretary Nominee


Jan 6, 2013 4:52pm

WASHINGTON, D.C. — President Obama will nominate former senator Chuck Hagel to be his next Secretary of Defense tomorrow.


Senior officials within the administration and Capitol Hill confirmed the pick to ABC News today after the Nebraska Republican had emerged as a frontrunner among potential candidates several weeks ago.


Hagel, 66, is a decorated Vietnam veteran and businessman who served in the senate from 1997 to 2009. After having sat on that chamber’s Foreign Relations and Intelligence Committees,  he has in recent years gathered praise from current and former diplomats for his work on Obama’s Intelligence Advisory Board as well as the policy board of the current Defense Secretary Leon Panetta.


But the former lawmaker faces an upscale battle in the coming confirmation hearings in Congress; critics on both sides of the aisle have taken aim at his record toward Israel and what some have called a lack of experience necessary to lead the sprawling Pentagon bureaucracy or its operations.


Progressives have also expressed concern about comments he made in 1998, questioning whether an “openly, aggressively gay” James Hormel could be nominated to an ambassador position by then-President Clinton. Hagel apologized for the comments last month, adding that he also supported gays in the military – a position he once opposed.


Who Is Chuck Hagel? Meet Obama’s Top Pentagon Pick


The friction with his former colleagues has left a degree of uncertainty in the air going into the hearings. Today on ABC’s “This Week,” Senate Republican Leader Mitch McConnell demurred when asked whether he would support the man who, in 2008, he had championed for his candidness and stature in foreign policy.


“I’m going to wait and see how the hearings go and see whether Chuck’s views square with the job he would be nominated to do,” he told George Stephanopoulos.


Senator Lindsey Graham was more blunt in his opposition to Hagel on CNN. The Georgia Republican called Hagel an “in your face nomination,” and said he “would be the most antagonistic secretary of defense towards the state of Israel in our nation’s history.”


If confirmed, Hagel will join a crop of new cabinet members expected to join the president in his second term, including Sen. John Kerry, D-Mass., who was nominated in December to replace Hillary Clinton as Secretary of State.


ABC’s Elizabeth Hartfield and Devin Dwyer contributed reporting.

Turkey lifts ban on thousands of books






ISTANBUL: From communist works to a comic book, thousands of titles banned by Turkey over the decades were taken off the restricted list Saturday, thanks to a government reform.

In July, the parliament adopted a bill stipulating that any decision taken before 2012 to block the sale and distribution of published work would be voided if no court chose to confirm the ruling within six months.

The deadline came and went Saturday and no such judicial decisions were recorded, the head of Turkey's TYB publisher's union, Metin Celal Zeynioglu, told AFP.

"All bans ordered by (the courts in the capital) Ankara will be lifted on January 5," city prosecutor Kursat Kayral confirmed to AFP.

Kayral had announced last month that he would let lapse every ban in his jurisdiction, a decision that cleared 453 books and 645 periodicals in that area alone.

Among them were several communist works such as the "Communist Manifesto" written by Karl Marx and Friedrich Engels, as well as writings by Soviet tyrant Joseph Stalin and Russia's revolutionary leader Vladimir Lenin.

Others included a comic book, an atlas, a report on the state of human rights in Turkey and an essay on the Kurds.

But the books under Kayral's jurisdiction make up only a fraction of all the titles affected, a total of up to 23,000 works according to Zeynioglu, who said he learned the number from the justice ministry.

The ministry did not immediately confirm the total, a number that Zeynioglu added was hard to nail down.

"These bans weren't implemented in a centralised fashion: they were ordered by different institutions in different cities at different times," he said.

"Besides, most have been forgotten over the years and publishers have resumed printing the banned books."

As an example, the complete works of Turkish poet Nazim Hikmet, who died in exile in Moscow in 1963, had already been stocked in libraries for years despite the ban.

The reform is thus largely symbolic, and some are sceptical of whether it reflects any true change within the Turkish state.

"The mindset hasn't changed and people (in the administration) will continue to do whatever they think is right," said Omer Faruk, a former head of the Ayrinti publishing house.

He cited as an example the fate of one of his published books: the erotic "Philosophy in the Bedroom" by French writer Marquis de Sade.

Deemed licentious, the text was banned, but the Supreme Court overturned the decision. Yet "despite the ruling, the book continues to be seized", Faruk said.

This scepticism is reinforced by the ruling Islamic-rooted Justice and Development Party's record in matters of freedom of speech.

The Committee to Protect Journalists said last month that Turkey had, at 49 people, the highest number of journalists behind bars, with most of them Kurds.

In late November, Prime Minister Recep Tayyip Erdogan himself took the directors of a television series to task, saying their script was in conflict with history and Muslim morals.

"Those who toy with the people's values must be taught a lesson," Erdogan said.

But despite his reservations, Zeynioglu said there would be at least one concrete result of letting the bans lapse.

"Many of the students arrested in demonstrations are kept in prison because they're carrying banned books," he said.

"From now on, we won't be able to use that as an excuse."

Windows laptop sales sink -- but that's just part of the problem



Will businesses and consumers spring for a Windows 8 hybrid priced at $849 that's powered by a relatively pokey Atom processor?

Will businesses and consumers spring for a Windows 8 hybrid priced at $849 that's powered by a relatively pokey Atom processor?

Windows 8 PC sales aren't trending well, according to a new report. And consumers' addiction to low cost may be a factor.


A blurb on Friday from the NPD Group said
Windows 8 holiday sales continue to not impress.


"The launch of Windows 8...did little to boost holiday sales or improve the yearlong Windows notebook sales decline," NPD said.


More specifically, Windows laptop "holiday unit sales" were down 11 percent year-to-year, the market researcher said.


Want more deets? The average selling price of a Windows laptop rose a hair -- $2 to $420, according to NPD.



Meanwhile, the average selling price of a MacBook rose almost $100 to $1,419 on a sales drop of 6 percent.


Upshot: Both Windows lappies and MacBooks saw sales decrease, but Apple made a $100 average selling price gain versus a couple of bucks for Windows.


Maybe a bigger part of the Windows sales problem is that the mix of systems has changed compared with the glory days of
Windows 7.


That is, Windows 7 was accompanied by a crush of ultracheap netbooks, according to an analysis at the Supersite for Windows -- which had some harsh words for netbooks.


"Many of those 20 million Windows 7 licenses each month -- too many, I think -- went to machines that are basically throwaway, plastic crap. Netbooks didn't just rejuvenate the market just as Windows 7 appeared, they also destroyed it from within," Paul Thurrott wrote.


"Now consumers expect to pay next to nothing for a Windows PC. Most of them simply refuse to pay for more expensive Windows PCs."


And, by the way, shipments of systems powered by Intel's power-efficient-yet-lower-performance Atom chip -- the same class of processors used in netbooks -- are barely a trickle at this point. And to make matters worse, some, like the $849
HP Envy x2, are priced way above the $399 netbooks of holiday seasons past.

There is a counterpoint to the NPD report, however. Analysts have told CNET that demand for touch-screen Windows 8 PCs in the U.S. is strong. Rhoda Alexander, an analyst at IHS iSuppli, told CNET last month that some vendors can't keep touch-screen PCs on the shelf.

So, if supply of touch-screen displays eases and system prices drop a bit, that could drive more sales. And prove to be an advantage over Apple, which doesn't have any touch-screen MacBooks.


At $749, Samsung's Intel Atom chip-based ATIV Smart PC is about $300 more than a Windows 7 Netbook.
