DUDE !!!! Turn Your Computer Off !!!!!



Seriously, this is good advice (Photo: Createblog)

What do you do when the power goes out? What happens when you can’t surf the web or watch TV, and when even the battery on your mobile phone runs out? After the initial shock dissipates into low-grade frustration, it’s common to feel a strange sense of liberation. When you can’t work or even procrastinate, you end up doing the things you’ve been putting off, whether that’s reading a long-neglected book or having a chat with the neighbours.

There’s a good reason why we sometimes look back on blackouts and blizzards fondly as times when we’re jolted out of our routines, so is it worth pulling the plug deliberately once in a while, and having a modern ’secular Sabbath’.

The increasing power and affordability of ever-connected phones and computers means that we can now access effectively limitless content at any time, anywhere. For some, this firehose of information is a curse rather than a blessing, largely because they feel that most online content is a useless waste of time (e.g. millions of cat videos).

Clearly this isn’t true. Putting new-fangled multimedia content aside for the moment, hundreds of excellent articles, interviews, essays and blog posts are published every single day on every conceivable topic, each worthy of note and deserving of readers. Even the most hardened luddite will appreciate how the internet gives us access to the world’s stock of newspapers, magazines, blogs, and books – so whether you’re interested in the situation in South Korea, architecture in Pakistan, the impact of low cost space travel, or the history of the Atlantic ocean, you’re bound to find something good.

No, if there’s a real criticism of the internet, it’s not that there’s too little good content – it’s that there’s too much. Blogs like Arts & Letters Dailyand The Browser can help us discover good content, but leave them for more than a day and you’ll begin slipping behind, wondering if you’ve missed something great. The same goes for the unremitting stream of Facebook and Twitter status updates and emails that we all receive from friends and colleagues. We’re all cursed by a Sisphean struggle to clear our inboxes, but no sooner than we declare ‘inbox zero’ does it fill again with yet more to be processed.

The fact is, you can’t finish the internet. It’s not like a book or a newspaper where you can reach the final page and pause before beginning something else, you just keep on going, following chains of links to new articles and comments and videos forever. The internet appeals to the ‘love of the new’ that’s characteristic of all humans – we’re all neophiles, always curious to see what’s beyond the hill on the horizon.

If we all had better self-control, this vast array of choice wouldn’t be a problem, but as Barry Schwartz has written in The Paradox of Choice, an abundance of choice can be paralysing, whether for brands of food at a supermarket or for works of art.

Beyond a certain point, we actually get unhappier and more indecisive the more choice there is – we worry whether we’ve made the right choice, and what we might be missing. Online, you’re always missing something.

Armed with this knowledge, though, there is a clear solution – artificially limiting our own choices. It sounds odd, but it works. At Cambridge, a friend was having real problems getting enough work done when he was constantly being distracted by this new-fangled internet we all had in our rooms. After a week of fretting, he landed upon the simple tactic of unplugging his network cable whenever he wanted to finish an essay. I remember laughing at this – didn’t he have enough self-control to just not surf the internet? – but then again, he’s the one who got the First, not me.

The idea of limiting our access to technology and the work or distraction that brings is hardly new; the Sabbath has been observed by Jews for over five thousand years, with similar traditions among Seventh-day Adventists and others. Most people today don’t observe a day of rest, preferring to have the freedom to shop and party and watch TV seven days a week, but when I began learning more about the Sabbath, I struck upon the idea of a ’secular Sabbath’ – a day without technology _ with my friend Naomi Alderman.

On a particular Friday, I arrived home before sunset and instead of turning everything on, I turned it all off – my laptop, my TV, and after a pang of worry about urgent calls and emails, my iPhone. It felt tremendously liberating – not only had I shut off the firehose of information, but it wasn’t even worth worrying about work or chores because there was absolutely nothing I could do about them for the next 24 hours. Instead, we just talked and read books.

Without the bright lights and loud music of bars, I also realised exactly how tired I was from the week, and I ended up going to bed correspondingly earlier. In the morning, I read a book, went for a walk, and had some friends over to visit for lunch. I’d abandoned the treadmill of emails and constant work and blogs and was taking time to do things that mattered.

In the evening, the sabbath was ending and I turned on my iPhone again. Amazingly, the world was still standing – there were a few emails and Tweets, but nothing urgent. I was recharged and relaxed by the sheer lack of choice I’d imposed on myself for the day.

I don’t intend to have a secular Sabbath every week, but it’s certainly something worth thinking about whenever you feel overwhelmed. In 2011, the pressures and choices and distractions in our lives are only going to increase. Sometimes you just need a day of rest.






Everyday objects in close-up

Several items brought to life at a MILLION times magnification


Images showing the everyday objects taken for granted by householders have been brought to life at a MILLION times magnification. Using the world's most expensive kind of microscope - a Scanning Electron Microscope (SEM) - scientists have revealed the characteristics in miniature, giving a tour of the home as a tiny new world. Stunningly detailed 3D pictures as you've never seen before reveal the hidden secrets of items found around the home.

SEMs - far more powerful than regular light microscopes that can only magnify by up to 1000 times - build extreme close-ups of anything that can fit inside the 4ft high device by bombarding it with electrons. The electrons send back messages which help to build up a super-accurate image - revealing every tiny feature of the pollen grains down to the last cranny - in wondrous fashion.

Panasonic’s EVOLTA Robot Completes a New Challenge
Panasonic’s robo-man succeeds in another feat of strength. This time, the EVOLTA Robot travels 500 kilometers through Japan powered by two rechargeable NiMH AA batteries.
Panasonic’s EVOLTA Robot finished a long journey in December. The green-and-white robotic man charged up the ancient Tokaido roadway in Japan, traveling from Tokyo to Kyoto. The 500-kilometer trip took EVOLTA Robot (or EVOLTA-kun, as he is known in Japan) two months to complete.


EVOLTA-kun pulled a green wagon and ran inside a treadmill wheel. He traversed the uneven pavement and sloping hills of the Tokaido using the same two rechargeable AA batteries throughout the trip.
EVOLTA-kun from Panasonic travels 500 kilometers from Tokyo to Kyoto on NiHM batteries.


The EVOLTA left Tokyo on Sept. 23, 2010. At each of 53 stations along the Tokaido thoroughfare, the EVOLTA stopped to recharge its batteries.



At his final station, the Sanjo Bridge in Kyoto, the EVOLTA Robot was greeted by adoring fans and hard-working Panasonic team members. The robot’s designer Tomotaka Takahashi, along with the four “EVOLTA Sisters” who had accompanied EVOLTA-kun during his journey, gave speeches and told stories about the two-month ordeal.
In front of the audience, EVOLTA-kun broke a Japanese sake barrel top using a wooden hammer. The act is part of Japanese tradition.
PREVIOUS FEATS
This is not the first time Panasonic’s EVOLTA Robot has made the news. Two years ago, the EVOLTA climbed a 530-meter rope to the top of the Grand Canyon in 6 hours and 46 minutes. The following year, in 2009, the EVOLTA Robot finished the 24-hour Le Mans endurance race of 23.726 km. This latter feat earned the little green-and-white robo-man a place in the Guinness World Records for the longest distance covered by a battery-operated, remote-controlled car.
Two alkaline batteries were used for both challenges.

YikeBike, a new sort of bike .... you should try it


YikeBike review (Engadget)

Want to meet a bunch of random strangers everywhere you go? Start riding around on a neon green electric bicycle that looks like nothing this world has seen before, something tossed out of a passing UFO that some New Zealand shepherd found glowing slightly as it rested in the middle of a smoking crater. This $3,595 electric bicycle with a 15mph top speed and six mile range does come from New Zealand, but the YikeBike is very much a product of human ingenuity, or so creator Grant Ryan claims, but that doesn't stop it from giving us a riding experience that is nothing short of other-worldly. Unfortunately, that doesn't necessarily equate to a entirely perfect experience.


A penny-farthing for these times

Yeah, we're not particularly keen on the name "YikeBike" either; it sounds like a Ferengi gambling term or an epithet hurled in some harsh foreign language. Over the course of our testing we were asked many times "What is that thing?" Each time we responded with "YikeBike" the follow-up question was "What?" Perhaps this is proof that the name doesn't exactly stick, but it is certainly odd enough to describe this very odd cycle.

It's something like a modern interpretation to the penny-farthing style bicycle. You know, the old timey ride with a giant wheel up front, tiny one out back, bowler hat wearing gentleman perched precariously up top, high enough to make one wonder how he got there in the first place. 

The YikeBike is thankfully much smaller, its front tire having a diameter of just 20-inches. This is a little bigger than that purple or blue (or both) Huffy you had as a kid, with a rear wheel just 8-inches inches across. It's a strange looking bird, but it isn't odd for the sake of turning heads. That little rear wheel collapses and tucks inside the front, which is almost entirely enclosed by an all carbon fiber shroud containing the battery pack, motor, and probably some kryptonite too.

Likewise the handlebars fold down, the seat tucks away, and the whole thing turns into a puck that, with the addition of a padded shoulder strap, becomes a 23lb back appendage that is, unfortunately, rather larger than George Jetson's briefcase and a bit too large to carry on to a flight. However, it's plenty small enough to work on a subway or other means of public transportation where it could fill the gap between the closest stop and your destination. It's also light enough to carry up some stairs, but we wouldn't recommend lugging it for too long. We think your chiropractor would agree.


The folding and unfolding process takes about 20 or 30 seconds, naturally getting quicker the more times you do it, involving a handful clamps and folds. Sadly there is no button you can press to have the thing automatically furl and unfurl, an addition that would really knock the socks out of those slack-jawed passers by -- adding unneeded cost and complexity in the process.

However, one simple thing that really is missing is some form of kick stand. There's simply no way to keep the thing from falling over except for leaning it against something. When folded it's basically round and decidedly top-heavy, so even propping it up can be a challenge. Some sort of little fold-down center stand is really needed.


On the back is an array of decidedly conspicuous LEDs that act as brake and turn signals -- yes, there are little buttons on the handlebars that let you indicate a turning direction. Just in front of those buttons are a pair of even brighter LEDs that act as makeshift headlights. No, they won't deliver sweet comeuppance to those xenon blinders in their luxury cars, but they will at least let you see far enough to get home safely after yet another late-night production deployment.

Learning to ride

Five wobbly feet into our first ride on the YikeBike it became painfully clear that motorcycle and bicycle experience isn't going to help much here. The YikeBike is steered by handlebars that sit at your sides, on stalks that extend from behind the seat. Turning the bars turns the front wheel, feet either side on pegs that fold down from that swoopy carbon cowling. Meanwhile the seat is really attached to the rear wheel.





It's a bit odd, to have your feet and the front wheel turn while your body keeps looking straight. If you want to experience it, hop on the handlebars of a friend's bike and have him let you steer, just be aware that if you fall over and break something we will not be held liable. 

Thankfully on the YikeBike you're much lower, so falling over is a lot harder. Squeeze the throttle too hard (a trigger on the right grip) and you might just lose your balance, but you can always just put a foot down. Alternately if you hit the brake too hard (a trigger on the left grip) the bike does an immediate endo, bucking you out of the seat. This may sound dangerous, but it actually feels quite natural: you just stand up. 

Regardless of how cool such a dismount may look the idea is naturally to ride in control, and YikeBike the company recommends 30 minutes in an open area of slow-speed riding to get used to things before you get too crazy. There's even something of a grenade pin that fits in the throttle (which is cheekily shaped like the bike itself), preventing newbies from inadvertently quick getaways. 

It took us about 15 minutes before we felt comfortable pulling the pin. Rebels, we know. Like snowboarding or riding a motorcycle it actually got easier the faster you went, so once we got over our early wobbles we felt comfortable giving it a bit more stick -- with restraint. An itchy trigger finger can still send you into a wee tank-slapper, and the touchy regenerative brakes do take some practice. But, we didn't fall once and didn't scrape a single knee, which is more than we can say for learning to ride a bike as a kid. All this without training wheels!

Saddling up

The seat on the YikeBiks is, in bicycle terms, rather generously sized and padded -- more Huffy than Selle. That said, after a few minutes of cradling it with your nether regions it begins to... irritate. That's thanks to the riding position that sees you placing almost your entire weight on that seat.

On a bicycle some amount of your mass is supported by the handlebars and some by the pedals. Here, though, with your feet out front and your hands down at your sides most of your weight is on your kiester and, well, after a little while things start to get a little sore. We're thinking frequent cyclists won't mind so much, but if your cheeks haven't embraced a bike seat in awhile prepare for an acclimatizationperiod. 

Try as we might we alas weren't able to get up to that 15mph top speed, at least not according to GPS, not even with a slight downhill run. Our best was about 13.5mph, though perhaps with a little more breaking in than our virgin steed had experienced things would roll more smoothly. Also, due to a series of blizzards we haven't been able to get as much road time as we'd have wanted, but battery life thus far has given us little reason to doubt the six mile range estimate from the company.

It's abundantly clear that this is not an all-terrain machine, though: the tire is a slick and the only suspension is provided by whatever cushioning nature gave you. YikeBike assured us the machine is fully waterproof, and indeed we bisected some puddles without getting electrocuted or a skunk stripe up our backs, but it seemed like a shame to get something this lovely all covered in excessive road grime.

When depleted you'll need to break out a generously sized charging brick, which has an annoying little fan that spins away to presumably keep the aluminum box from combusting. A charge takes about 45 minutes, which is quite acceptable, but having to use that charging brick is a bit of a bother. If you're looking to charge on the go it means you'll either need to take it with you or cough up another $100 for a second one. Given the weight of the brick and the total cost of the bike we'd say the extra $100 isn't so bad.

One thing we wouldn't spring for is the paint. This is actually the first painted YikeBike in the world -- initial shipping models are available in any color you like so long as it's carbon fiber. That early status shows, with a few paint flaws jumping out at us as soon as the bike sprang from its container and a couple scratches seemingly self-manifesting through the course of our testing. The company will soon offer a range of colors for those with a bit of patience, but we'd stick with the raw carbon. 


If all the import tuners can flaunt their carbon wings and other meaningless add-ons to their cars, why can't you show off the weave of your bike that's entirely made of the stuff?

Wrap-up


We obviously can't wholeheartedly recommend that everyone go out and buy a YikeBike because it is, after all, a somewhat goofy and rather niche product that costs over $3,500. But, happy day for those who fit in that niche: someone who doesn't have a particularly long way to go; someone who wants an EV but has to charge it inside their home; someone who likes to support innovation; someone who, it must be said, has a fair amount of disposable income. If that's you, break out the credit card and get ready to have some fun.

And that niche will be expanding a bit soon, with extra battery packs that will extend the bike's range and turn it into more of a practical commuter. Even then the YikeBike won't fit into the lives of an awful lot of people, and we can't help feeling intense jealously toward those for whom it does.

Power Knee motorized prosthetic officially available in US, Europe



Power Knee motorized prosthetic officially available in US, Europe -- race of cyborgs still in infancy

We reported on Ossur's robotic prosthetic back in 2009, and now amputees in Europe and the United States have become the first official recipients of the Power Knee. According to the company, "the world's first and only motor-powered prosthetic knee" was recently approved for reimbursement by the German National Health System, covered by private insurance in France and the UK, and picked up by select healthcare providers in the US. Power Knee combines "artificial intelligence," motion sensors, and wireless communication to learn and adjust to the walking style of its users -- that's one small step for real-life cyborgs and one giant leap for prosthetic technology.

Amputees Receive Ossur's New POWER KNEE(TM), the World's First Motorized Prosthetic Knee -- Company Marks Significant Commercialization Milestone

REYKJAVIK, ICELAND -- Lower-limb amputees in Europe and the U.S. are among the first to receive the new POWER KNEE, the world's first and only motor-powered prosthetic knee, it was announced today by Össur, a recognized global leader in prosthetic and orthopaedic innovations.





"For four decades, Össur has been developing innovations to help people enjoy lives without limitations," said Jon Sigurdsson, president and CEO. "The new POWER KNEE is the latest extension of Össur's unrivaled Bionic Technology platform, which also includes the industry-leading RHEO KNEE® and PROPRIO FOOT® prostheses."

Össur recently marked a significant milestone in POWER KNEE's commercialization process, with the first reimbursement by the German National Health System, and the first private insurance coverage for POWER KNEE amputees in France and the UK. In the U.S., a select number of prosthetic practices and healthcare institutions also have been certified as POWER KNEE providers.

Conventional prostheses require an amputee to consciously move them by directly engaging the anatomical structures of their remaining limb. In comparison, POWER KNEE is the first prosthetic knee designed to function as an integrated extension of its user, using battery-powered capabilities to address the lost muscle capability and asymmetrical movement often found in people with limb loss.

Like all of Össur's advanced Bionic prostheses, POWER KNEE is a "smart" prosthetic limb. Its integrated artificial intelligence (AI) systems, sophisticated motion sensors and wireless communications capabilities enable POWER KNEE to "learn" its user's walking style and automatically make real-time adjustments based on changes in speed, stride, or terrain. POWER KNEE's early users report that they have been able to conserve energy, more confidently negotiate obstacles and inclines, and cover greater distances than they previously could.

Physicists build world's first antilaser


Less than a year after it was first suggested, the world’s first antilaser is here. A team of physicists have built a contraption that, instead of flashing bright beams, utterly extinguishes specific wavelengths of light.

Conventional lasers create intense beams of light by stimulating atoms to spit out a coherent beam of light in which all the light waves march in lockstep. The crests of one wave match the crests of all the others, and troughs match up with troughs.
The antilaser does the reverse: Two perfect beams of laser light go in, and are completely absorbed.
“There will be nothing coming out again,” said experimental physicist Hui Cao of Yale University, whose research group built the new device.
The device could find uses in fields from computing to medical imaging, the researchers report in the Feb. 18Science.
Yale physicist A. Douglas Stone, a coauthor of the paper, first suggested the antilaser in a theoretical paper last July. Stone and colleagues had noticed that several other researchers had hinted at the idea of a laser that runs backward, and some problems in engineering called for a way to completely snuff out light. But no one had ever put the two ideas together.
“Others discovered independently that there’s an optimal condition where they can have the best absorption,” Cao said. “But they didn’t realize this was a time-reversed laser. They didn’t know they can get in principle perfect absorption.”
To build the antilaser, which Cao and colleagues call a “coherent perfect absorber,” the researchers split a beam from a titanium-sapphire laser in two. The laser emitted light in the infrared part of the electromagnetic spectrum, with longer wavelengths than the human eye can see.


Some of the light continued forward through the beam splitter, and the rest was forced into a sharp right turn. The physicists guided the light beams into a cavity containing a silicon wafer one micrometer thick. One beam entered from the left and one from the right. The distance each beam travels determined the way the crests and troughs of the light waves aligned when they met in the wafer.


When the alignment was right, the light waves canceled each other out. The silicon absorbed the light and converted it to another form of energy, like heat or electrical current.
“It is a simple experiment,” Cao said. “But it shows a very powerful way to control absorption.”
The device can only absorb one wavelength of light at a time, but that wavelength can be adjusted by changing the thickness of the wafer.
Surprisingly, the antilaser switched from absorbent to reflective when the researchers changed the way the waves met in the wafer. Under certain conditions, the silicon crystal actually helped light escape.
“That is a little surprising,” Cao said. “We can turn it on and off.”
Theoretically, 99.999 percent of the light can be extinguished. Because of the physical limitations of the laser and the silicon wafer, the antilaser only absorbed 99.4 percent of the light.
That may be good enough, Cao says.




“For many applications, if you already have less than 1 percent coming out, you’re already okay,” she said. “I’m sure people in the community who have better lasers than us, I’m sure they will achieve much more impressive results. This is only the first demonstration of the principle.”
The device may find uses in optical switches for future super-fast computer boards that use light instead of electrons. It may also have medical applications, such as imaging a tumor through normally opaque human tissue.
The most exciting applications will no doubt be the ones no one has thought of yet. The laser itself was called “a solution without a problem” when it first showed up.
“It is quite novel and indeed surprising that in such a mature field one can come up with something fundamentally new,” said physicist Marin Soljačić of MIT, who was not involved in the new work. “I think it opens a few exciting venues.”




Cubelets: modular, affordable robotics for kids and students

Cubelets: modular, affordable robotics for kids and students

Robotics can be a tricky subject to teach children, and it's hard to know where to start. Cubelets is a system of modular cubes that each have one use, interaction, or behavior, and by linking them together you can create easy to understand robots with impressive behavior. It's a great concept: you start with very basic ideas, and then by linking them together you can create something that can work in a variety of ways.

"Cubelets was originally called roBlocks and was a project I worked on while in grad school for architecture at Carnegie Mellon University in Pittsburgh," Eric Schweikardt, the creator of Cubelets, told Ars. He wanted a way to let people interact with digital models, and thought blocks was a good beginning. "I started to add more functionality into the different cubes and Cubelets evolved out of that. I never intended to make and sell a product, but after the 20th lab visitor asked when they could buy them, I started to warm to the idea." Smart move: the first batch of 100 beta kits has already sold out.

Each $300 kit comes with 20 blocks, and they're classified as either action, sense, or utility. The official site has some information on how they can be used, as well as a brief demonstration video. "If you make a simple robot by connecting a Light Sensor block to a Speaker block, they'll start to talk, and when the light in the room gets brighter, the Speaker will get louder." Each robot requires the battery block for power, and you can continue adding from there. "Next, you could swap the Speaker for a Drive block, and when the light gets brighter, the robot will drive faster," Schweikardt continued. "Maybe you'd want to put an Inverse block in between the Light Sensor and Drive blocks. Then the robot would drive slower as the light gets brighter."

It sounds simple, but the 20 blocks allow for a variety of behaviors and experimentation.

Cubelets
"The neat thing about Cubelets is that while each of the individual blocks is easy to understand, when you snap a few of them together, the robot can behave in rather astonishing ways," Schweikardt told Ars. "Since the blocks are responding to real-world sensor input, their behavior can be remarkably responsive and lifelike. It's easy to put together robots that behave like animals—and that's led a few people to comment that Cubelets can be an interesting model for understanding how the beauty and complexity of real life could, in fact, have evolved from simple, understandable components."

Right now the market is hobbyists and informal education, and Schweikhardt thinks science centers and children's museums would be a good fit. Soon they'll be creating the Cubelets in large quantities, and the price will go down, making the blocks affordable for anyone interested in robotics.

Since the blocks are modular, there is no end to what sort of blocks and behavior could be added in the future. "We're working on lots of different sensors, but my three favorites are the Hinge Block, which can be daisy-chained to create snake robots, the Prismatic Block, where one face extends to two times the block length, and the Bubble Blowing Block." We're voting for a teeny-tiny, adorable machine gun block ourselves.

Cubelets is a great idea, and watching them work in video form makes me want to put something together. We're hoping to get our hands on a loaner set soon to give you the lowdown on build quality and ease of use, but for now you can request information on future availability directly from the manufacturer.
















Green Goose, sensors that monitor your life


We're pretty certain that once embedded wireless sensors catch on, they'll pervade every aspect of ourlives, and Green Goose is building a microcosm of that eventuality in the form of a role-playing game. The five-person SF Bay Area startup has embedded custom 915MHz radios and MEMS accelerometers in a variety of tiny transmitters which you can mount to household objects -- like a water bottle, bicycle, or the toothbrush above -- which report back to the receiver with your actions and thereby increase your score. Brush your teeth on time, take your vitamins, or exercise repeatedly within a couple hundred feet of the receiver, and you'll eventually level up. (Or, optionally, muck with the sensor just right, and it'll register points anyhow.) Presently, that level isn't worth anything, but founder Brian Krejcarek says there are tentative plans to tie these points into a real game and an API to build the idea out, and he's presently looking for partner companies here at the Launch Conference in San Francisco to help roll out the sensors (which cost approximately $4 each) under branded marketing initiatives of some sort. If you don't want to wait, the company will sell starter kits starting February 28th for $24. Not bad for a head start on the future, right?
