5 Cyber Monday Scams to Avoid

5 Cyber Monday Scams to Avoid(Thinkstock)
It’s the holidays, and everybody wants a piece of you.
“Cyber Monday,” the online counterpart to Black Friday, is not just a busy time for e-tailers. It’s also high season for scammers, who want a taste of the $2.6 billion online shoppers are expected to drop on the biggest online shopping day of the year.
Cyber con artists usually want one of three things: your money, your identity, or your computer. They aim to drain your bank account, use your online credentials to hide their tracks, and turn your computer into a tool they remotely control and rent out to other scammers.
The standard attack comes to you in a “phishing” email, a message that looks like it came from someone you trust, like your bank, employer, or a brand-name retailer. These emails are designed to lure you into opening a file attachment or visiting a website that steals your information or infects your computer. Phishing attacks can also come in online advertisements.
A recent study by brand protection firm Mark Monitor says one in six online consumers is duped into shopping at rogue sites. Another study shows that a quarter of all Facebook ads for luxury goods are for third-party knockoffs, like fake Rolex watches and faux Louis Vuitton bags.
The key component to these scams: you. You have to think that something bogus is the real deal and, just for a moment, treat it as such. Avoiding these scams isn’t particularly difficult. But if you’re not paying close attention (or you’ve had too much of Uncle Bob’s Southern Comfort eggnog) you could end up making a mistake that will cost you a lot, for a long time to come.
Here are five of the more common scams to watch out for:
1. Craaazy Cyber Monday specials.

OMG, $15 for an iPhone 5 and $76 for an iPad? I’ll take half a dozen of each! (McAfee)

Some crazy Cyber Monday deals are a little too crazy, which is why anything advertising brand-name electronics at bargain-basement prices should be greeted with extreme skepticism. But greed — or unbridled optimism — often tempts you to click anyway. What happens next?
One scenario is that the ad leads you to a website that wants to steal your information or infect your computer. It could be a bait and switch: That super-cheap iPad is suspiciously out of stock, replaced by models with a heftier price tag; or the price doesn’t include extra-cost “accessories” (like a power supply, memory, or a manual). The goods might be customer returns or refurbished models being sold as new. They could be third-party knockoffs or counterfeit items. Or the site could simply take your credit card information and then vanish.

4 Ways to Take Better Care of Your Laptop’s Batteries

4 Ways to Take Better Care of Your Laptop’s Batteries
You likely spend more time on your laptop than with your significant other, your dog or — at the very least — your plants. So there’s no reason you shouldn’t treat it with the same tender loving care. Here are a few tips to ensure that your gadget’s battery has a long and happy life. 
(This guide is focused on lithium-ion batteries, which is what most modern laptops are packing. If you want to learn about how to care for other types of batteries, check out Battery University, a dense database of such things.)
1. Don’t get too attached.
When you plug your laptop in for the first time, you should make sure to fully charge it once to calibrate it. But after that, aim to keep it between 40 and 80 percent. Apple’s customer care says you should do this to “keep the electrons in it moving occasionally.” Wired has a better explanation of whyhere. But the bottom line is, doing this can help prolong your battery life by as much as four times. 
I know that’s easier said than done. Just remember to keep an eye on your battery percentage (usually shown in a corner of your screen) throughout the day. If you leave your laptop at home, then shut it down, close it and keep it unplugged on a desk, not a couch. 
You should also fully charge and discharge your computer’s battery at least once a month. Set a reminder on your phone or something. You forked over what I assume to be a ton of money for this thing, so paying attention to it once a month shouldn’t be a problem.
2. Stay cool.
Most modern laptops are made with lithium-based batteries, which should be stored in temperatures between 50 and 95 degrees Fahrenheit. You might not always be able to keep tabs on that sweet spot, so to make things a bit simpler, room temperature is fine. 
That being said, there are a few ways you can make sure your laptop isn’t constantly having menopausal hot flashes. You should start by minding its air vents. Most MacBook vents are located on the back of the laptop, near the top of the computer. Whenever you prop your laptop up on your bed, couch or lap, you’re likely blocking the airflow. This, in turn, causes the computer to overheat. And overheating will screw up your battery life.

That’s not to say you should be completely paranoid about keeping it on flat, cool surfaces all the time. But maybe consider moving it to a desk before you fall asleep or head to work.
3. Update, update, update.
Most companies are constantly looking for ways to improve battery life via software updates. In fact, it was one of the main things Apple touted in its OS X Mavericks release last year. You may fear change, but change can extend your battery life. So make sure you have the latest software installed on your computer.
4. Don’t just leave it there.
Maybe you’re in trouble with the law and need to disappear for six months. We understand how these things go. But that doesn’t mean you’re off the hook for correctly storing your computer. You should store it with a 50 percent charge in a consistently cool area. Storing the computer with a fully discharged battery might ruin the battery forever. And storing it with an absolutely full charge might cut the battery’s lifespan short.
Simple enough? Now go, be a better laptop owner. Your machine is counting on you.

MIT engineers have high hopes for cheetah robot

CAMBRIDGE, Mass. (AP) — It's a robot unlike any other: inspired by the world's fastest land animal, controlled by video game technology and packing nifty sensors — including one used to maneuver drones, satellites and ballistic missiles.
The robot, called the cheetah, can run on batteries at speeds of more than 10 mph, jump about 16 inches high, land safely and continue galloping for at least 15 minutes — all while using less power than a microwave oven.
It's the creation of researchers at the Massachusetts of Technology, who had to design key elements from scratch because of a lack of or shortcomings in existing technology.
That includes powerful, lightweight motors; electronics that control power for its 12 motors; and an algorithm that determines the amount of force a leg should exert during the split second that it spends on the ground while running — the key to helping the robot maintain balance and forward momentum. An onboard computer organizes data from various sensors and sends commands to each motor.
"This is kind of a Ferrari in the robotics world, like, we have to put all the expensive components and make it really that instinctive," said MIT Professor Sangbae Kim, who heads the school's Biomimetic Robotics Lab that designed the robot. "That's the only way to get that speed."
Insight gleaned from the design of their prototype could have real-world applications, including the design of revolutionary prosthetics, wearable technologies, all-terrain wheelchairs and vehicles that can travel efficiently in rough terrain much like animals do, Kim said. There are hopes the robot will be able to be used in search and rescue operations in hazardous or hostile environments where it's too risky to send a human rescuer.
"When the robot is running, at every step, we calculate the appropriate amount of the force to the legs so that the robot can balance itself," said MIT research scientist Hae-Won Park, who wrote the complex algorithm used to control the cheetah, which weighs around 70 pounds — about the same as one of its female feline counterparts.
Sensors inside the robot measure the angle of the leg and that information is sent to an onboard computer that also organizes data from the Inertial Measurement Unit, or IMU, which is also used to maneuver drones and ballistic missiles, Park said.
The project is funded by the U.S. Department of Defense's Defense Advanced Research Projects Agency. The military research arm is also funding a similar robot being developed by Boston Dynamics. The company says its version is powered by an off-board hydraulic pump and uses a boom-like device to keep it running in the center of the treadmill.
Crafting the cheetah robot took five years of designing, testing, tweaking and plenty of confidence to ignore those who said electric motors aren't strong enough to propel a running mechanical cheetah powered by batteries.
Researchers had to exercise a lot of patience during test runs. The robot broke dozens of legs manufactured by 3-D printers and reinforced with Kevlar strips and carbon fiber.
The results?
Strong, lightweight components that made untethered running possible, including a carbon fiber-and-foam sandwich frame that can absorb the forces generated by running and jumping.
Some off-the-shelf components, including an Xbox controller for maneuvering the robot and wireless Internet communications for sending commands to the mechanical cheetah, also came in handy.
Each leg is propelled by three motors that can generate powerful forces at slow speeds.
Still, researchers continue to tweak their prototype, looking to add additional sensors that would eventually make the robot autonomous.
"In the next 10 years, our goal is we are trying to make this robot to save a life," Kim said.

Collisions Between Drones And Airplanes Serious Concern, ‘Enforcing Regulations Difficult’ FAA Warns

Drone collision with airplane possible
The Federal Aviation Administration is warning drone hobbyists to heed regulations in order to prevent collisions between drones and airplanes.
According to CNN, Michael Huerta, head of the Federal Aviation Administration, notes that regulations are in place to prevent drones from interfering with large aircraft. However, not all drone operators are following the guidelines set forth by the FAA. The FAA hopes to increase education and enforcement of the laws that they feel are necessary to keep drones from interfering with airplane flights.
WTMA reports that the FAA is concerned about safety, as the number of cases involving aircraft and drones is increasing. Since February of this year, nearly 25 airplanes have had to change course due to near collisions with unmanned drones. Altogether, there were about 200 incidents involving drones since February, including the 25 that caused a diverting of course. Huerta said the concern is serious.
“That is certainly a serious concern and it is something that I am concerned about.”
As it stands now, FAA regulations prohibit operators from flying drones higher than 400 feet, near an airport, or out of eyesight. However, enforcing these regulations has proven difficult. Aside from identifying drone flyers not operating within the FAA’s rules, many drone operators may not be educated on proper use. Therefore, the FAA wants to spend more time educating the drone hobbyist community on how to safely fly a drone, not just prosecuting those who disregard regulations.
“We have been working with the Model Aeronautics Association, with the model community and clubs so we can educate people because these are not your typical pilots that may be flying one of these for the first time and they may be unfamiliar with the rules.”
Some drone proponents, however, would like to see free and open use of drones.
“Yes, there are proponents of unmanned aircraft and they really see huge potential with this technology and for them, we can’t move fast enough,” Huerta said. “What they would like to see is free and open use of unmanned aircraft as soon as we can get there.”
Huerta says that he understands their enthusiasm towards drone use, but wants them to consider the airplane pilots prospective. Drones are small and difficult to see for pilots. This means that a collision can be very difficult to avoid when a pilot does not know a drone is in the area or flight path. The FAA is looking at ways to appease both the airplane community, as well as drone operators. One suggestion is to find a way to certify the drone aircraft and operator.
“I can’t say what is going to be in it but broadly speaking, what we are looking at are all the questions relating to how we certify the aircraft and what are the qualifications of the operator as well as what uses they can be put to.”
What do you think of the FAA’s concerns regarding drones and standard airplane traffic? Does the FAA have a right to limit the use of drones to 400 feet?

Sony Hackers Steal DVD Rips? Torrents Appear After Hack

Did the Sony hackers steal DVD rips of unreleased movies? Less than a week ago, Sony Pictures was hacked. The hacking came with a massive Twitter takeover, involving perhaps more than two dozen of Sony’s accounts. The hack also came with a warning. If Sony didn’t comply with certain demands (these were never made public, and Sony claims to have never heard the list either), data would be released.
For a bit over an hour, several Sony accounts bore the image above, then the company regained access and was able to delete the tweets.

Security Week reports that the attack may have been by a North Korean hacker group known as Guardians of Peace, or #GOP. Here again, there’s nothing solid to confirm the fact, but Security Week shared some speculation about the motivation behind the attack:
“The Interview,” which stars Seth Rogen and James Franco as two journalists recruited by the CIA to bump off Kim, has infuriated the North Koreans, with state media warning of “merciless retaliation.”
So, did Sony’s hackers steal DVD rips while they were in the system leaving their message? Looks like there’s no one who can resist a good movie.

Can Video Games Teach Your Child to Be a Better Person?

One day about four years ago, I came home from work and heard utter mayhem coming from my son’s room: Russian voices, screeching tires, gunshots. I bolted up the stairs and threw open his door.
I found him parked in front of his Xbox, playing Grand Theft Auto IV. I watched his avatar lead police on a high-speed chase through the absurdly empty streets of Liberty City. He crashed a car into a light pole, hopped out of his car, and began emptying a .45 Magnum at the cops.
Can Video Games Teach Your Child to Be a Better Person?
(Thinkstock)
This game was most definitely not on the family approved-to-play list. My first instinct was to grab the Xbox and throw it out the window. My wife persuaded me to conserve my moral outrage for those moments when he did something dangerous or stupid in the real world, not in a virtual one.
Still, for a little while I felt like the world’s worst parent. Then I sat down and watched him play, and I also watched the story on the Xbox unfold before him. I realized that GTA is a dystopian satire not all that different from movies like A Clockwork Orange, which thoroughly outraged parents when I was his age. 
The idea that playing video games makes kids violent and antisocial is often accepted as a sobering fact of modern life. Whether it’s true is less clear — some studies say yesothers say nyet. In the real world, watching Clockwork did not make me into a droogie. And playing GTAdid not turn my son into a murderous thug. He’s a great kid.
But let’s assume the fear has some truth, that violent media contributes to violent behavior. If so — if games teach kids to shoot first and to drive as if cars are weapons — can’t games also be used to impart positive life skills like empathy or compassion? Can video games boost a child’s emotional quotient (EQ)?
Some people think they can. One of them is Trip Hawkins, founder of Electronic Arts, most famous for creating the most popular sports simulation game of all time, John Madden Football. Now he’s trying to prove it via a fantasy adventure game called IF… aimed at tweens.
You the dog, manJust as Madden Football is based on actual NFL playbooks, IF… is based on decades of research in social emotional learning (SEL). The game takes place in a land called Greenberry populated by dogs, cats, and magical Pokemon-like characters known as Vim. Long ago, the dogs and cats were driven apart by conflict, and Greenberry fell into ruin.
Guided by the Yoda-like YouDog, players must learn how to tame the Vim, resolve the conflicts, and bring Greenberry back to harmony. Along the way they’re presented with questions and a choice of answers measuring their degree of empathy and other SEL attributes.
image
You’ve got three choices. Pick the wrong answer, and you’ll get a lesson in sensitivity from YouDog.
Each chapter teaches 20 distinct SEL skills, such as listening, managing emotions, or expressing gratitude. As each chapter is completed, parents get a report detailing how well their child did. The first chapter of the book-like adventure is available for free in the iTunes Store. New chapters will start to become available in June for around $5 apiece.
To be frank, this is not the most exciting game your child will ever play. The first chapter is didactic, slow, and unlikely to lure anyone away fromMinecraft, Runescape, or Club Penguin. (I’m told things get livelier in Chapter 2.) But Hawkins says the rewards are more subtle and long lasting.
“This game is not about advancing in levels; it’s about teaching compassion,” he said. “You’re like the Jimmy Stewart character in It’s a Wonderful Life. You see how the town ends up in tatters without you, and it’s up to you to make it right.”
Learning to copeThough IF… is probably the most ambitious and well-funded attempt to employ gaming techniques to teach kids emotional skills, it’s not the only one. The Social Express uses Pixar-like animation to teach kids age 5 and up how to read emotional clues and react to them appropriately.
image
The Social Express starts by teaching kids how to recognize their own emotions, and then how to apply coping skills.
Rather than embed lessons inside the plot of a role-playing game, The Social Express uses brief webisodes that target specific situations and model appropriate behavior, CEO Marc Zimmerman says.
Kids can apply those lessons to their own lives via a 99 cent Android or iOS app called My Digital Problem Solver. My DPS lets kids choose an image that shows how they feel at the moment (frustrated, scared, mad, or whatever) and then select a coping strategy like taking deep breaths or “positive self talk” to calm down.
In use by more than 100 school districts across the country, The Social Express is also available to families for $5 a month per child. Parents can track their child’s progress through the lessons via a free mobile app.
IF….. and The Social Express are two examples of a small but growing genre of digital works that explore emotions besides fear and anger, which tend to dominate most video games, said Tanner Higgin, senior manager for education content at Common Sense Media.
“There’s a wide range of feelings like loneliness, trepidation, and guilt that have remained largely untapped,” he said. “Over the last few years we’ve started to see a lot more games that implicitly or explicitly build social skills and expand the emotional spectrum.”
The play’s the thingRespecting other people’s feelings, sharing, being empathetic — aren’t these things kids should be learning from their parents, not from a screen? I asked Janice Toben, founder of the Institute for Social and Emotional Learning, who consulted on the curriculum baked into IF… .
Yes, she replied. But she added that many parents lack the ability to model those traits themselves, especially during emotionally charged encounters with their children. So, for example, instead of calmly explaining that a violent video game is detrimental to a child’s emotional development, they are instead tempted to rip the cables from the Xbox and hurl it into the street. 
“Parents want to be able to create a common vocabulary around things like calming down, listening to each other, and getting along, but not everyone knows how to do it,” she said. “I think a game like IF… can help, if the parents are interested and involved.”
Research has shown that playing games can sharpen a child’s problem-solving skills (not to mention his aim and his reflexes). If games can boost his IQ, why not his EQ? At the very least it’s worth a shot — metaphorically speaking, of course.
