Researchers Set World Record Wireless Data Transmission Rate of 6 GB/Sec Over 37 KM (sciencedaily.com) 72

An anonymous reader quotes a report from Science Daily: Transmitting the contents of a conventional DVD in under ten seconds by radio transmission is incredibly fast -- and a new world record in wireless data transmission. With a data rate of 6 Gigabit per second over a distance of 37 kilometers, a collaborative project with the participation of researchers from the University of Stuttgart and the Fraunhofer Institute for Applied Solid State Physics IAF exceeded the state of the art by a factor of 10. The extremely high data rates of 6 Gbit/s was achieved by the group through efficient transmitters and receivers at a radio frequency of 71-76 GHz in the so-called E band, regulated for terrestrial and satellite broadcasting. The circuits are based on two innovative transistor technologies developed and manufactured by the project partner Fraunhofer IAF. In the transmitter the broadband signals are amplified to a comparatively high transmission power of up to 1 W with the help of power amplifiers on the basis of the novel compound semiconductor gallium-nitride. A highly directive parabolic antenna emits the signals. Built into the receiver are low-noise amplifiers on the basis of high-speed transistors using indium-gallium-arsenide-semiconductor layers with very high electron mobility. They ensure the detection of the weak signals at high distance. The transmission of high quantities of data by radio over large distances serves a high number of important application areas: the next generation of satellite communication requires an ever-increasing data offload from earth observation satellites down to earth. Supplying the rural area and remote regions with fast Internet is possible as shown in the trial. Earlier this year, engineers at the University of Illinois were able to set a record for fiber-optic data transmission, transmitting 57Gbps of error-free data at room temperature.

Comment Retool with a more interesting language (Score 1) 250

I can sympathize with not wanting to be a Java programmer in the enterprise space. Perhaps that's what makes the prospect of programming seem boring to her.

Different programming languages involve different thought processes, and work better in certain domains than others. If she's retooling anyway, perhaps she should look at other languages. I'm not sure what's hot in the Spanish job market at the moment, but perhaps looking for job listings from the type of company or organization she'd like to work for would give a hint as to what language to learn. If you want a few generic recommendations, then the ubiquitous Javascript (some modern style, not going to advocate for or against a specific framework or library), or the JVM centric Scala, or the niche-pervasive Python come to mind.

I'm going to avoid the sweeping generalizations about gender that seem to epidemic, and just suggest that the focus should be on the organization and problems to be solved, and not on the technology. If you like those, the job has potential to be interesting - and if the organization is any good, they'll have chosen a language that fits their problem space well.

Toyota's Fuel Cell Car To Launch In Japan Next March 216

puddingebola writes with news that Toyota will be bringing its first fuel-cell car to market in Japan next March. It's expected to cost about $68,700, and Toyota plans to bring it to the U.S. and European markets later that summer. With two of Japan’s three biggest automakers going all in on fuel cells, the country’s long-term future as an automotive powerhouse could now hinge largely on the success of what they hope will be an important technology in the next few decades. ... Japan’s governing party is pushing for ample subsidies and tax breaks for consumers to bring the cost of a fuel-cell car down to about $20,000 by 2025. The government is also aiming to create 100 hydrogen fuel stations by the end of March 2016 in urban areas where the vehicles will be sold initially. ... Hydrogen vehicles can run five times longer than battery-operated electric cars, and their tanks can be filled in just a few minutes, compared with recharging times from 30 minutes up to several hours for electric cars.

Comment There is an antisocial behavior precedent (Score 1) 183

In the bad old days, when there was another antisocial behavior that profoundly affected the innocent victims in adjacent seats, we divided the plane into smoking and non smoking sections. There was leakage from section to section, but at least it wasn't in your face.

Many Amtrak trains have a highly desirable "quiet car",which helps to separate those the see the trip along the east coast as a continuous sales call opportunity from those that see the trip as a continuous concentration or sleeping opportunity.

So, I'm all for allowing calls on planes, provided I can book a seat in the STFU section for no extra cost. Especially if it saves me from taking a transatlantic flight surrounded by a gaggle of teenagers that think it's a Beatles concert and not a redeye.

That's just the tip of the iceberg:

408k combined telemarketers and call centers (who provide a service widely reviled and high stress) in 201x with a US pop of ~ 308m.

Not more jobs, fewer. 50% fewer population adjusted.

Indy bookstores up from 1,401 in 2009 to 1,632 today. The final Border's closing wave? 399 stores. That's fewer jobs in bookstores, not more. Might be better jobs in this case.

Technology absolutely kills jobs, and kills careers. It also creates new jobs and new careers, but not necessarily for the people that lost their jobs. The fallacy comes from pretending that all jobs are equal and can be subsumed into a single total job count.

Doesn't mean I want to live like a Luddite, however. But TFAs above are rather thin on reasoning.

Turkey's Science Research Council Stops Publication of Evolution Books 444

An anonymous reader writes "The Scientific and Technical Research Council of Turkey (TÜBITAK) has put a stop to the publication and sale of all books in its archives that support the theory of evolution, daily Radikal has reported. The books have long been listed as “out of stock” on TÜBTAK's website, but their further publication is now slated to be stopped permanently. Titles by Richard Dawkins, Alan Moorehead, Stephen Jay Gould, Richard Levontin and James Watson are all included in the list of books that will no longer be available to Turkish readers. In early 2009, a huge uproar occurred when the cover story of a publication by TÜBITAK was pulled, reportedly because it focused on Darwin’s theory of evolution."

Comment So? Send 'em a check! (Score 1) 562

Seems like the answer is pretty simple to me: Verizon customers should send them a check until they drop this policy. Note that I didn't say "drop your online payment option and send them a check." Simply send them a check, for a little bit too much, a week before your automatic billing date. They can sort out how to handle the expense of processing all of those checks, plus cancelling (or reversing, even better) the automatic payment for that cycle, deal with the trivial credit balances on the account, and generally be miserable. If they charge you automatically with the service fee, complain that the service was already paid for. If you and 10,000 of your closest friends do this, the policy will change in one month. If they refuse your alternate payment in any fashion, call your state attorney general, the BBB, enterprising consumer reporters, and the rest of the usual suspects.

Or just shrug and go along with it as most consumers do, which is why this is a smart move for Verizon. Wait until you get a "wire maintenance fee" for the charger on your cell phone.

If you're going to spend $700 on a video card, you'll probably spend on monitors too, especially since monitors tend to have a longer usable life cycle than video cards.

Show me free software/free drivers running four to six physical displays with full 3d acceleration. Let me choose whether it's a single desktop with one logical display, a single desktop with multiple logical displays, or multiple desktops. While I'd personally prefer GNU/Linux of a Debian flavor, ship it for any open environment you want, we'll take care of the rest.

Ship this software environment at the same time you release the card. Betas and patches are fine. Yes, that means collaborate in advance, and leave behind the last vestiges of pretense about competitive advantage via secrecy. Marketing, do-not-discuss-before-date NDAs are fine. Withholding the engineering data that will eventually be public anyway is counterproductive.

Comment The question is the software and the data formats (Score 1) 1217

Parent post got part way there - yes, the web and HTML is a great way to deliver content.

However, the key here is what _software_ the students will be expected to run in order to _author_ content.

For those of you Windows zealots that haven't bothered to try a Mac, please be aware that it's perfectly possible to run MS Office. But it's also possible to run Apple's iWork suite, or OpenOffice. Or Google Apps in the browser.

It's very common for IT departments in all types of organizations to choose to support a single OS platform. It's equally common for competent power-users in those organizations to opt-out and use the platform of their choice - but to take on the responsibility of self support. Those policies are usually written in draconian tones "we only support X, you must use X" - but in practice it's easier to keep the power users occupied self-supporting their unapproved platforms than have them hacking away at your standard ones.

The thing that makes or breaks this situation is the software platform chosen. I'd be a lot more concerned about requirements to submit classwork in native Pages (the iWork word processor) format than I am the choice of official supported hardware. If the software and data formats are reasonably compatible with multiple platforms, things will work out.

It's fine for them to choose a supported platform. It's not fine for them to make it gratuitously difficult for others to self-support. If a group of determined parents and students want to use Linux environments instead, it should be possible - not supported, but possible. Similarly if they want to have a Windows group, so be it. This school hasn't made the mistake of blocking this - yet, or at least according to the data available to us.

Now, for those who haven't actually laid hands on a MacBook side by side with an equivalently equipped other laptop, you really ought to do so before asserting the value for your dollar spent. Heck, run Linux on both for a week, taking the OSX out of the equation, and see what think. It's premium hardware, and sometimes that's worth it and has a lower TCO. Looking only at the initial purchase price is foolhardy.
