Comment Re:units . . . (Score 1) 70

You've forgotten that the Hz represents cycles/s, not just 1/s. Hence their so-called "spectral efficiency" is 5.7 bits/cycle. The problem of course is that the article does not address the SNR nor the BER that it took them to get that 5.7 result. If you need cryo-tech photodetectors and massive FEC to get that result, it's less impressive than doing it with the existing kit and minor data redundancy.

An there we were thinking that Target had all those real-time customer-linked analytics watching our eyeballs as we strolled the shelves and trotting out the offers we couldn't refuse. Now it turns out they're just as incompetent as the next bunch of monkeys. We can breathe again, at least for a little while...

Submission + - Multivitamin researchers say "case is closed" as studies find no health benefits (cbsnews.com)

schwit1 writes: “Enough” with the multivitamins already.

That’s the message from doctors behind three new studies and an editorial that tackled an oft-debated question in medicine: Do daily multivitamins make you healthier?

After reviewing the available evidence and conducting new trials, the authors have come to a conclusion of “no.”

“We believe that the case is closed — supplementing the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers, published Dec. 16 in the Annals of Internal Medicine. “These vitamins should not be used for chronic disease prevention. Enough is enough.”

They went on to urge consumers to not “waste” their money on multivitamins.

1947? Hell, everyone has always been racist and always will be. Can't help it. Xenophobia is in the genes because it is a survival-trait behaviour. We just change our perceptions about which "race" we apply our zenohobia to. Right now, we mainly apply it to machines. Come the singularity, machines will be racist too. We can only hope that they will find us amusing pets rather than serious threats.

That's getting close. Talk to your auditors too. Let them figure out what the liability is, and they'll persuade the board to take action. Meanwhile, get your incident response plan ready. Once the intrusions start, you'll have a lot of people breathing down your neck looking to know how to respond.

Submission + - Scientists 3D-print 300m lithium-ion batteries (techienews.co.uk) 1

hypnosec writes: Harvard scientists have managed to 3D-print 300m lithium-ion batteries – the size of grain of sand – that could possibly pave way for new era of micro-electronics. The 3D-printed battery is thinner than that of a human hair and can be used to supply electricity to tiny robotic devices, medical implants as well as those devices that have been powerless for the want of such tiny batteries. According to Jennifer Lewis, a materials scientist at Harvard, 3D-printing of the battery was possible thanks to two important developments. Lewis’ first invention is “what she calls functional inks that can solidify into batteries and simple components, including electrodes, wires, and antennas." Second is the development of nozzles and high-pressure extruders that are used to squeeze out the batteries and other components from the 3D-printer.

Submission + - Online Shopping: Hazardous to Junk Food's Health (reuters.com)

Rambo Tribble writes: Reuters is reporting that the trend toward online shopping is reducing the sales of impulse-purchase items, most notably candy and snacks often displayed at the checkout counter. As even grocery shopping shifts online, junk food producers are feeling the squeeze.

Described at https://github.com/dotcloud/docker/tree/v0.7.0, "Docker is an open source project to pack, ship and run any application as a lightweight container Docker containers are both hardware-agnostic and platform-agnostic. This means that they can run anywhere, from your laptop to the largest EC2 compute instance and everything in between - and they don't require that you use a particular language, framework or packaging system. That makes them great building blocks for deploying and scaling web apps, databases and backend services without depending on a particular stack or provider. Docker is an open-source implementation of the deployment engine which powers dotCloud, a popular Platform-as-a-Service. It benefits directly from the experience accumulated over several years of large-scale operation and support of hundreds of thousands of applications and databases." Might be interesting, but like many other projects, they seem to be incapable of expressing concepts in basic English, e.g. who needs it, what does it do, etc.

Submission + - What a Difference a Light Bulb Makes (slate.com)

mdsolar writes: There’s a simple technology that transforms our lives every day, and yet we rarely give a passing thought to its existence (unless of course it flares out at an inopportune moment): the light bulb. And yet for more than a billion people in the developing world who lack access to electricity, this simple device can make an unimaginable difference....a family with a light bulb is a family with opportunities. Women can set up small shops in their homes, for instance, to sew or cook for extra money. Kids can study for school: A light may keep a girl or boy from dropping out. Families read, or may use the light to set up classes to teach others to read. A shop owner keeps his or her store open longer, earns more money, sends more kids to school—and those kids can then use the glow to read in the evenings. That’s why there are dozens of organizations around the world dedicated to nothing more than making sure that people have access to light.... [N]early unbreakable LEDs are easily paired with solar power, and so in poor communities, what seems excessive to us becomes a long-lasting investment that bypasses both inefficient incandescents and the lumbering power grid.
