Get a free DVD ripper, video converter, and ringtone maker

It's been a fun series of freebies this week! Free seasons of TV shows (now expired, alas), free movies from Vudu, a free membership to ShopRunner -- and today, to top it all off, some free software.

Before I tell you about it, I'm going to ask that you please read the instructions as I've outlined them below, as these giveaways always seem to trip up some readers. There's nothing complicated here, but if you don't pay attention, you'll end up e-mailing me about what a fake or scam or screw-up this is.

So. From now until Jan. 2, 2013, Digiarty Software is giving away its WinX iPhone iPad Video Pack, a bundle consisting of three programs:
iPad DVD Ripper (which also rips to iPhone and other formats), iPhone Video Converter (which isn't just for iPhone), and iPhone Ringtone Maker. This threesome is for Windows only.

Here's how you get it:

1. Click the giveaway link above or right here.


2. Click the green Get License Code button.


3. Ignore (at least for the moment) the top half of the box that appears. Do NOT click the inviting orange Buy Now button. Remember, there's nothing to buy today.


4. Instead, click the Download link near the bottom of that box, the one under WinX iPhone iPad Video Pack Giveaway.


5. That Zip file contains the installers and license codes for all three programs. (The codes are listed inside a text file.) Once you install and run any one of the programs, you'll need to copy and paste in the corresponding license code to register it -- otherwise you'll end up with just a trial version.

The only "catch" is that you have to use those license codes -- that is, register the programs -- no later than Jan. 3, 2013.

As I noted above, the DVD ripper and video converter may have iPad and iPhone in their names, but the truth is they can produce video formats that are compatible with most devices. It may take a little fiddling and guesswork to rip a DVD for play on, say, your
Android phone, but it should be do-able.

I've had good luck with Digiarty's utilities in the past, and although these are provided without tech support or free upgrades, they're definitely worth your time if you're looking to rip DVDs, convert videos, or create iPhone ringtones (though this last is just as easily accomplished with any number of free iPhone apps). Even if they don't get the job done for some reason, hey, they didn't cost you anything.

If I don't see you again until 2013, have a safe and happy holiday. And remember: the best things in life really are free. Hugs. Compliments. Acts of kindness. Declarations of love. Give them generously. I'll start: I love all you folks and thank you profusely for spending a few minutes of your day here. It means a lot.

Bonus deal: Get 'em while they're hot (pink): Today only, Lenovo has the IdeaPad A1107 16GB Android 4.0 tablet for $129 shipped when you apply coupon code USPAD21213 at checkout. (I just tried the code and it worked, though I'm not sure for how much longer.) The IdeaPad features 16GB of storage, dual cameras, Bluetooth, and a 7-inch screen. It's pink, though, so this one's probably best suited to the lay-deze...

Winter Solstice 2012: Facts on the Shortest Day of the Year

Today is the winter solstice and the first day of winter in the Northern Hemisphere. It's all due to Earth's tilt, which ensures that the shortest day of every year falls around December 21.

Some predicted that today would also mark Earth's doomsday, thanks to a longstanding rumor that the Maya calendar ends on December 21, 2012. But earlier this year, National Geographic grantee William Saturno found evidence that the Maya calculated dates thousands of years past 2012.

"We keep looking for endings," Saturno said in a statement. "The Maya were looking for a guarantee that nothing would change. It's an entirely different mindset."

(Read more about the Maya apocalypse myth.)

Even without an apocalypse, the solstice has been an auspicious day since ancient times. Countless cultural and religious traditions mark the winter solstice; it's no coincidence that so many holidays surround the first day of winter.

Solstice in Space: Astronomy of the First Day of Winter

During the winter solstice the sun hugs closer to the horizon than at any other time during the year, yielding the least amount of daylight annually. On the bright side, the day after the winter solstice marks the beginning of lengthening days leading up to the summer solstice.

"Solstice" is derived from the Latin phrase for "sun stands still." That's because—after months of growing shorter and lower since the summer solstice—the sun's arc through the sky appears to stabilize, with the sun seeming to rise and set in the same two places for several days. Then the arc begins growing longer and higher in the sky, reaching its peak at the summer solstice.

(Related sun pictures: See a full year in a single frame.)

The solstices occur twice a year (around December 21 and June 21) because Earth is tilted by an average of 23.5 degrees as it orbits the sun—the same phenomenon that drives the seasons.

During the warmer half of the year in the Northern Hemisphere, the North Pole is tilted toward the sun. The northern winter solstice occurs when the "top" half of Earth is tilted away from the sun at its most extreme angle of the year.

Being the shortest day of the year, the winter solstice is essentially the year's darkest day, but it's not the coldest. Because the oceans are slow to heat and cool, in December the seas still retain some warmth from summer, delaying the coldest of winter days for another month and a half. Similarly, summer doesn't hit its heat peak until August, a month or two after the summer solstice.

Winter Solstice Marked Since Ancient Times

Throughout history, humans have celebrated the winter solstice, often with an appreciative eye toward the return of summer sunlight.

Massive prehistoric monuments such as Ireland's mysterious Newgrange tomb (video) are aligned to capture the light at the moment of the winter solstice sunrise.

Germanic peoples of Northern Europe honored the winter solstice with Yule festivals—the origin of the still-standing tradition of the long-burning Yule log.

The Roman feast of Saturnalia, honoring the God Saturn, was a weeklong December feast that included the observance of the winter solstice. Romans also celebrated the lengthening of days following the solstice by paying homage to Mithra, an ancient Persian god of light.

Many modern pagans attempt to observe the winter solstice in the traditional manner of the ancients.

"There is a resurgent interest in more traditional religious groups that is often driven by ecological motives," said Harry Yeide, a professor of religion at George Washington University. "These people do celebrate the solstice itself."

(Related: Get Stonehenge facts and pictures in National Geographic magazine.)

Pagans aren't alone in commemorating the winter solstice in modern times.

In a number of U.S. cities a Watertown, Massachusetts-based production called The Christmas Revels honors the winter solstice with an annually changing lineup of traditional music and dance from around the world.

"Nearly every northern culture has some sort of individual way of celebrating that shortest day," said Revels artistic director Patrick Swanson. "It's a lot of fun for us to dig up the traditional dance and music and even the plays [honoring] that time of the year."

Of course, as the name suggests, The Christmas Revels mix ancient winter solstice traditions with customs of the holiday that largely replaced winter solstice celebrations across much of the Northern Hemisphere: Christmas.

Winter Solstice's Christmas Connection

Scholars aren't exactly sure of the date of Jesus Christ's birthday, the first Christmas.

"In the early years of the Christian church, the calendar was centered around Easter," George Washington University's Yeide said. "Nobody knows exactly where and when they began to think it suitable to celebrate Christ's birth as well as the Passion cycle"—the Crucifixion and resurrection depicted in the Bible. (Related: "Christmas Star Mystery Continues.")

Eastern churches traditionally celebrate Christmas on January 6, a date known as Epiphany in the West. The winter date may have originally been chosen on the basis that Christ's conception and Crucifixion would have fallen during the same season—and a spring conception would have resulted in a winter birth.

But Christmas soon became commingled with traditional observances of the first day of winter.

"As the Christmas celebration moved west," Yeide said "the date that had traditionally been used to celebrate the winter solstice became sort of available for conversion to the observance of Christmas. In the Western church the December date became the date for Christmas."

Early church leaders endeavored to attract pagans to Christianity by adding Christian meaning to existing winter solstice festivals.

"This gave rise to an interesting play on words," Yeide said. "In several languages, not just in English, people have traditionally compared the rebirth of the sun with the birth of the son of God."

1 Week Later: Moment of Silence at Sandy Hook

Incessant rain and a dreary morning failed to keep onlookers away from a moment-of-silence memorial in Newtown, Conn., to pay their respects to the 26 people who were killed at Sandy Hook Elementary School.

Officials scheduled the event to recognize victims of the massacre that began at 9:30 a.m. Dec. 14, when gunman Adam Lanza shot his way into Sandy Hook elementary and launched a shooting spree at the school, taking 26 lives, including 20 children, and then his own.

FULL COVERAGE: Newtown, Conn., Elementary School Shooting

Tents and plastic were used to protect the stuffed animals, candles, notes and pictures that mourners have set up in the town. Flags in Newtown, Conn., which encompasses the village of Sandy Hook, are flying at half-staff.

Gov. Dannel P. Malloy, Lt. Gov. Nancy Wyman and Newtown First Selectman Patricia Llodra, together with other local elected officials, convened on the steps of Edmond Town Hall in Newtown for the moment of silence.

They congregated on the steps at 9:28 a.m., with the moment of silence beginning at 9:30 a.m.

President Obama also took part in the moment of silence at the White House. The White House tweeted this morning, "20 beautiful children & 6 remarkable adults. Together, we will carry on & make our country worthy of their memory. -bo #MomentForSandyHook." The "-bo" signature means the tweet was sent by the President himself.

Bells from nearby Trinity Episcopal Church rang 26 times this morning in memory of each life lost at Sandy Hook Elementary School, as did the bells at the National Cathedral in Washington.

No formal remarks were made during the memorial.

Malloy has proclaimed today a "day of mourning" in Connecticut, asking residents statewide to participate in the moment of silence. He also wrote the nation's governors, inviting each state in the country to participate in the reflection on this day.

On the Web, a movement sprung up to make sites automatically "go silent" at 9:30. Easy-to-install javascript code was included so those who wanted their site to go silent could easily do so.

Lanza, 20, fatally shot his mother last Friday and then entered Sandy Hook elementary by shooting his way through a window to gain entry. From there, he gunned down and killed 26 people, including 20 children.

Laser cookery makes your food more fun

YOUR toast pops up with a strange pattern burned into it. Pointing your phone's camera at the pattern pulls up a website showing the day's traffic news for your commute. Later, as you're wondering how to make a spring roll, you notice the instructions are etched into the rice paper itself.

These are just a couple of the applications of "laser cookery" envisaged by Kentaro Fukuchi and colleagues at Meiji University in Japan. They reckon laser cutters have done their time in industry and, like 3D printers before them, it's now time for them to come into our homes - as a new breed of laser-enabled kitchen appliances.

At a cookery technology workshop in Nara, Japan, in November, the researchers showed how a benchtop industrial laser cutter - normally used to cut or engrave patterns in plastic, wood and metal - could generate a variety of fascinating foodstuffs when hooked up to a computer running graphics software and a webcam.

One delicacy they have developed is the charmingly named "melt-fat raw bacon", an allegedly tasty sliver of uncooked bacon on which the fat is cooked by the laser, using a webcam trained on the bacon to guide the beam. "The well-cooked fat and the fresh taste of the meat can then be experienced at the same time," says Fukuchi. Don't all rush at once.

Third quarter US growth revised up to 3.1%

WASHINGTON: The US economy grew 3.1 percent in the third quarter, faster than previously estimated, the Commerce Department said Thursday.

Gross domestic product growth in the July-September period was revised upward from prior estimates of 2.7 percent and 2.0 percent, the department said.

The higher figure reflects upward revisions to consumer spending, exports and government outlays, and downward revision to imports.

In the second quarter, real GDP increased 1.3 percent.

The Commerce Department said the revision "has not greatly changed the general picture of the economy for the third quarter except that personal consumption expenditures is now showing a modest pickup, and imports is now showing a downturn."

Online holiday shoppers spend $35 billion so far this season

Online spending for the first 46 days of the holiday season hit $35 billion, according to data out yesterday from ComScore.

Covering November 1 through December 16, the surge in sales represents a 13 percent jump over the same period last year. Last week set a record with spending surpassing $7 billion for the first time ever.

Green Monday (a term coined by eBay to refer to the second Monday in December) saw sales of $1.275 billion, while three other days for the season accounted for more than $1 billion in online spending.

However, the 13 percent rise is lower than expected, according to ComScore, as online spending has slowed in recent weeks. The research firm is waiting to see if last-minute shoppers can ring up more sales before the season ends.

"This current week, which kicked off with Free Shipping Day on Monday the 17th, will be critical in making up some ground on a season-to-date growth rate that remains below initial expectations at 13 percent following a prolonged post-Cyber Monday lull," ComScore chairman Gian Fulgoni said in a statement.

With many retailers extending their free shipping offers into Tuesday and Wednesday of this week, we just may see the sort of late-season jolt needed to push growth rates back into the mid-teens."

Detecting Rabid Bats Before They Bite

A picture is worth a thousand words—or in the case of bats, a rabies diagnosis. A new study reveals that rabid bats have cooler faces compared to uninfected colony-mates. And researchers are hopeful that thermal scans of bat faces could improve rabies surveillance in wild colonies, preventing outbreaks that introduce infections into other animals—including humans.

Bats are a major reservoir for the rabies virus, according to the Centers for Disease Control and Prevention (CDC) in Atlanta. Previous research shows that bats can transmit their strains to other animals, potentially putting people at risk. (Popular Videos: Bats share the screen with creepy co-stars.)

Rabies, typically transmitted in saliva, targets the brain and is almost always fatal in animals and people if left untreated. No current tests detect rabies in live animals—only brain tissue analysis is accurate.

Searching for a way to detect the virus in bats before the animals died, rabies specialist James Ellison and his colleagues at the CDC turned to a captive colony of big brown bats (Eptesicus fuscus). Previous studies had found temperature increases in the noses of rabid raccoons, so the team expected to see similar results with bats.

Researchers established normal temperature ranges for E. fuscus—the bat species most commonly sent for rabies testing—then injected 24 individuals with the virus. The 21-day study monitored facial temperatures with infrared cameras, and 13 of the 21 bats that developed rabies showed temperature drops of more than 4ºC.

"I was surprised to find the bats' faces were cooler because rabies causes inflammation—and that creates heat," said Ellison. "No one has done this before with bats," he added, and so researchers aren't sure what's causing the temperature changes they've discovered in the mammals. (Related: "Bats Have Superfast Muscles—A Mammal First.")

Although thermal scans didn't catch every instance of rabies in the colony, this method may be a way to detect the virus in bats before symptoms appear. The team plans to fine-tune their measurements of facial temperatures, and then Ellison hopes to try surveillance in the field.

This study was published online November 9 in Zoonoses and Public Health.

Schools Threatened Nationwide After Sandy Hook

Schools across the country, already on edge following last week's massacre of 20 students and six adults at a Newtown, Conn., elementary school have been further unnerved following a series of copycat threats, sometimes yielding arrests and caches of deadly weapons.

From California to Connecticut, police in the past five days have arrested more than a dozen individuals in Indiana, South Carolina, Maryland and elsewhere who were plotting or threatening to attack schools.

"After high-profile incidents like the shootings at Columbine and Sandy Hook, threats go off the wall. Some of those threats turn out to be unfounded, but sometimes those incidents propel people planning legitimate threats," Ken Trump, a national school safety consultant, told ABCNews.com.

CLICK HERE FOR AN INTERACTIVE MAP AND TIMELINE OF THE SANDY HOOK SHOOTING.

Many of these incidents turned out to be little more than young people acting out or seeking attention, but in some cases police found significant stockpiles of firearms and ammunition.

Just a few hours after the world learned what happened inside the halls at the Sandy Hook elementary school, police arrested a 60-year-old Indiana man who had allegedly threatened to "kill as many people as he could before police stopped him," according to the police report, at an elementary school in Cedar Lake, Ind.

Maryland Student Hospitalized for Alleged Threat Watch Video

When Von Meyer was arrested, just 1,000 feet from Jane Ball Elementary School, police confiscated from his home $100,000 worth of guns and ammunition including 47 weapons.

The school was placed on lockdown.

Meyer's case was taken by the Lake County public defender's office, but an attorney has not yet been assigned. He has been charged with seven crimes, including felonious intimidation, and an automatic "not guilty" plea was made on his behalf at a hearing on Tuesday.

Many of the suspects arrested in the wake of the Connecticut shooting were themselves school students – teenagers or young adults.

On Wednesday, in Laurel, Md., an unidentified student at Laurel High School was taken to the hospital and placed under psychiatric evaluation after school security officials found maps of the school and lists of students they believed he planned to kill.

Authorities called the evidence a "credible threat." The student, however, was not arrested or charged with a crime.

In Columbia, Tenn., police arrested Shawn Lenz, 19, who on Saturday posted to Facebook that he felt like "goin on a rampage, kinda like the school shooting were that one guy killed some teachers and a bunch of students."

He later told police that "it was stupid" to have written what he did. Lenz was arraigned Tuesday on terrorism and harassment charges and was appointed a public defender. He did not enter a plea.

A Tampa, Fla., school was put on lockdown two days in a row, Tuesday and Wednesday, after students found bullets on a school bus. Police there have made no arrests.

Despite the rash of recent threats, anecdotal data compiled by Trump's National School Safety and Security Services and analyzed by Scripps Howard found that there were approximately 120 known but thwarted plots against schools between 2000 and 2010. The list is not comprehensive and many incidents likely went unreported.

Fifty-five of those known threats -- all thwarted -- involved guns and 22 of them involved explosive devices, according to the Scripps Howard report.

"We're getting better at preventing these situations," Trump told ABC News.com.

But in that same time there were about 50 lethal school shootings, including the killing of 32 people at Virginia Tech.

"While shootings statistically may be rare, they impact a community and these kids forever," said Trump.

Cassini captures spectacle in Saturn's shadow

Flora Graham, deputy editor, newscientist.com

(Image: NASA/JPL-Caltech/SSI)

Like a Christmas bauble hanging in the night, this view of
a backlit Saturn shines in the darkness. The image was taken during a rare chance
for NASA's
Cassini spacecraft to observe the planet's rings while in Saturn's shadow. Conveniently,
Saturn blocks the sun and the rings are illuminated from behind.

As well as providing a unique view of an already enchanting
world, the image reveals details in the rings that aren't easily seen in direct
sunlight. The picture is a composite of
infrared, red and violet-spectrum photos taken by Cassini in October and
released this week.

The last opportunity for Cassini to spot Saturn from this
angle was in 2006, when NASA created a mosaic of images that revealed
previously unknown faint rings around the planet.

The two tiny dots in the lower left-hand quarter of the
photo are two of Saturn's moons, Enceladus and Tethys. Enceladus is closer to
the rings; Tethys is below and to the left. Previous Cassini fly-bys
discovered that Enceladus
is a geologist's paradise of snaking ridges, chasms and scratches,
while Tethys hosts a mysterious
spear-shaped feature.

US Vice President Joe Biden to head panel on gun violence

WASHINGTON: President Barack Obama on Wednesday will appoint Vice President Joe Biden to head a government panel to formulate a response to gun violence after last week's school massacre, US media reported.

The New York Times and the Washington Post cited White House officials as saying that Obama would formally name Biden to head the panel at a press conference later Wednesday morning.

The panel will explore possible new gun legislation to rein in the sale of assault rifles and high-capacity magazines, but will also look at mental health policies and violence in popular culture.

Obama vowed to take action against gun violence when he spoke at a memorial on Sunday for the 26 victims - including 20 young children - killed in the massacre at Sandy Hook Elementary School in Connecticut.

On Tuesday Obama backed a new bid to revive an assault weapons ban and other new gun laws, as traumatized US politicians wrestled with the aftermath of the worst in a series of mass shootings over the last two years.

The massacre shocked the country, and may have shifted the political debate on firearms in US society after years of gun lobby ascendancy.
