How the Rollout of 5G Will Change Everything 216

Posted by samzenpus from the sliced-bread-and-this dept.
mrspoonsi writes The global race is on to develop 5G, the fifth generation of mobile network. While 5G will follow in the footsteps of 4G and 3G, this time scientists are more excited. They say 5G will be different — very different. "5G will be a dramatic overhaul and harmonization of the radio spectrum," says Prof Rahim Tafazolli who is the lead at the UK's multimillion-pound government-funded 5G Innovation Centre at the University of Surrey. To pave the way for 5G the ITU is comprehensively restructuring the parts of the radio network used to transmit data, while allowing pre-existing communications, including 4G and 3G, to continue functioning. 5G will also run faster, a lot faster. Prof Tafazolli now believes it is possible to run a wireless data connection at an astounding 800Gbps — that's 100 times faster than current 5G testing. A speed of 800Gbps would equate to downloading 33 HD films — in a single second. Samsung hopes to launch a temporary trial 5G network in time for 2018's Winter Olympic Games.

Clarificiation on the IP Address Security in Dropbox Case 152

Posted by samzenpus from the read-all-about-it dept.
Bennett Haselton writes A judge rules that a county has to turn over the IP addresses that were used to access a county mayor's Dropbox account, stating that there is no valid security-related reason why the IP addresses should be exempt from a public records request. I think the judge's conclusion about IP addresses was right, but the reasoning was flawed; here is a technically more correct argument that would have led to the same answer. Keep Reading to see what Bennett has to say about the case.

Is Ruby On Rails Losing Steam? 291

Posted by Soulskill from the only-among-left-handed-geriatric-haberdashers dept.
itwbennett writes: In a post last week, Quartz ranked the most valuable programming skills, based on job listing data from Burning Glass and the Brookings Institution. Ruby on Rails came out on top, with an average salary of $109,460. And that may have been true in the first quarter of 2013 when the data was collected, but "before you run out and buy Ruby on Rails for Dummies, you might want to consider some other data which indicate that Rails (and Ruby) usage is not trending upwards," writes Phil Johnson. He looked at recent trends in the usage of Ruby (as a proxy for Rails usage) across MS Gooroo, the TIOBE index, the PYPL index, Redmonk's language rankings, and GitHut and found that "demand by U.S. employers for engineers with Rails skills has been on the decline, at least for the last year."

People Trained To Experience an Overlap In Senses Also Receive IQ Boost 68

Posted by timothy from the taste-the-rainbow dept.
Zothecula writes Tasting lemons when they see a number seven, regarding a certain letter as being yellow in color. Not a great deal is known about why some people experience an overlapping of the senses, a phenomena known as synesthesia. But a new study conducted at the University of Sussex has suggested that specific training of the mind can induce the effects of the condition. The study even suggests that such training can boost a person's IQ.

Joey Hess Resigns From Debian 450

Posted by Soulskill from the so-long-and-thanks-for-all-the-patience dept.
An anonymous reader writes: Long-time Debian developer Joey Hess has posted a resignation letter to the Debian mailing list. Hess was a big part of the development of the Debian installer, debhelper, Alien, and other systems. He says, "It's become abundantly clear that this is no longer the project I originally joined in 1996. We've made some good things, and I wish everyone well, but I'm out. ... If I have one regret from my 18 years in Debian, it's that when the Debian constitution was originally proposed, despite seeing it as dubious, I neglected to speak out against it. It's clear to me now that it's a toxic document, that has slowly but surely led Debian in very unhealthy directions."

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days 986

Posted by timothy from the there's-an-obvious-way-to-silence-the-critics dept.
WheezyJoe (1168567) writes The E-Cat (or "Energy Catalyzer") is an alleged cold fusion device that produces heat from a low-energy nuclear reaction where nickel and hydrogen fuse into copper. Previous reports have tended to suggest the technology is a hoax, and the inventor Andrea Rossi's reluctance to share details of the device haven't helped the situation. ExtremeTech now reports that "six (reputable) researchers from Italy and Sweden" have "observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, "far more than can be obtained from any known chemical sources in the small reactor volume."... "The researchers, analyzing the fuel before and after the 32-day burn, note that there is an isotope shift from a "natural" mix of Nickel-58/Nickel-60 to almost entirely Nickel-62 — a reaction that, the researchers say, cannot occur without nuclear reactions (i.e. fusion)." The paper (PDF) linked in the article concludes that the E-cat is "a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding. Moreover, the E-Cat results are too conspicuous not to be followed up in detail. In addition, if proven sustainable in further tests the E-Cat invention has a large potential to become an important energy source." The observers understandably hedge a bit, though: The researchers are very careful about not actually saying that cold fusion/LENR is the source of the E-Cat’s energy, instead merely saying that an “unknown reaction” is at work. In serious scientific circles, LENR is still a bit of a joke/taboo topic. The paper is actually somewhat comical in this regard: The researchers really try to work out how the E-Cat produces so much darn energy — and they conclude that fusion is the only answer — but then they reel it all back in by adding: “The reaction speculation above should only be considered as an example of reasoning and not a serious conjecture.”

Four Dutch Uberpop Taxi Drivers Arrested, Fined 282

Posted by timothy from the not-so-laissez-faire dept.
An anonymous reader writes with news that authorities in the Netherlands have arrested four drivers sharing their car for money through the Uberpop app. The drivers were then released with a fine of EUR 4,200 (USD 5,300) each and further threatened with additional fines of EUR 10,000 (USD 12,600) for each time they might be caught doing it again. While similar bullying applied to short rentals of private rooms through sites like Airbnb hasn't had the same success so far the thoughts go to the fined drivers, hoping they won't ever be caught carrying their grandmother to the supermarket then have to explain how they dared. Uber says it will "fully support" the affected drivers."

Smart Gun Inspires Smart Mouse Authentification System 60

Posted by samzenpus from the give-it-a-squeeze dept.
dcblogs writes Defense contractor Raytheon has received a patent for a mouse that has a biometric pressure grip. It believes the pressure grip, as a form of authentication, will be particularly hard to defeat because it works from a neurological pattern versus a physical pattern, such as a facial scan. "It's not just how much pressure you exert on the mouse itself, but it's also the x-y coordinates of your position," said Glenn Kaufman, a cybersecurity engineer. The approach was inspired by similar pressure grips used in smart guns.

How President Nixon Saved/Wrecked the American Space Program 125

Posted by Soulskill from the only-nixon-could-go-to-luna dept.
MarkWhittington writes John Callahan posted an accountof a talk given by space historian John Logsdon on the Planetary Society blog in which he described how President Richard Nixon changed space policy. The talk covered the subject of an upcoming book, After Apollo: Richard Nixon and the American Space Program. Logsdon argued that Nixon had a far more lasting effect on NASA and the American space program than did President Kennedy, most famous for starting the Apollo project that landed men on the moon.

Nixon came to office just in time to preside over the Apollo 11 lunar mission. At that time, the space program was a national priority due to the Kennedy goal of landing a man on the moon by the end of the 1960s. However by the time Neil Armstrong made that first footstep, public support for large-scale space projects had diminished. Nixon, therefore, made a number of policy decisions that redound to this very day.

Cyanogen Inc. Turns Down Google, Seeing $1 Billion Valuation 107

Posted by Soulskill from the go-big-or-go-home dept.
An anonymous reader writes: According to a report at The Information (paywalled), Cyanogen Inc., the company trying to commercializa the popular CyanogenMod mobile OS based on Android, recently met with Google's Android chief to talk about an acquisition. The report says Cyanogen turned down Google's offer and instead seeks funding from investors and major tech companies at a valuation around $1 billion. "Cyanogen has told potential investors that it has a deal in place to bring its custom version of the Android OS to India through a manufacturer called Micromax. Alongside Samsung, Micromax currently holds almost as much share of the smartphone market in India, making this deal a very large step to get Cyanogen into the hands of millions of more people. Lastly, the report claims that Cyanogen should be wary of modifying Android too much. During the process, the company must continue to follow Google's compatibility requirements which ensure third-party applications will work on their devices. If those requirements are not met, devices will not be licensed to run Google's services, such as Google Play and other Google applications."

Solar Could Lead In Power Production By 2050 167

Posted by timothy from the we-could-all-be-dead-by-then dept.
Lucas123 writes Solar power could be the leading source of electricity compared with other renewables and conventional sources of power, such as oil and coal, according to a pair of reports from the International Energy Agency. PV panels could produce 16% of the world's electricity, while solar thermal electricity (STE) is on track to produce 11%. At the end of 2013, there had been 137GW of solar capacity deployed around the world. Each day, an additional 100MW of power is deployed. One reason solar is so promising is plummeting prices for photovoltaic cells and new technologies that promise greater solar panel efficiency. For example, MIT just published a report on a new material that could be ideal for converting solar energy into heat by tuning the material's spectrum of absorption. Ohio State University just announced what it's referring to as the world's first solar battery, which integrates PV with storage at a microscopic level. "We've integrated both functions into one device. Any time you can do that, you reduce cost," said Yiying Wu, a professor of chemistry and biochemistry at Ohio State.

Android Apps Now Unofficially Able To Run On Any Major Desktop OS 101

Posted by timothy from the crash-early-and-often dept.
An anonymous reader writes A developer who goes by the handle Vladikoff has tweaked Google's App Runtime for Chrome (ARC) to allow any Android app to run on any major desktop operating system, not just the handful announced last week which were also limited to Chrome OS. His tweaked version of ARC is re-packaged as ARChon. The install isn't very straightforward, and you have to be in developer mode on Chrome. But there's a support forum on reddit. The extension will work on any OS running the desktop version of Chrome 37 and up as long as the user also installs chromeos-apk, which converts raw Android app packages (APKs) to a Chrome extension. Ars Technica reports that apps run this way are buggy, fast, and crash often but expresses optimism for when Google officially "opens the floodgates on the Play Store, putting 1.3 million Android apps onto nearly every platform."

Ask Slashdot: How To Avoid Becoming a Complacent Software Developer? 275

Posted by Soulskill from the become-a-complacent-manager-instead dept.
An anonymous reader writes: Next year will be the start of my 10th year as a software developer. For the last nice years I've worked for a variety of companies, large and small, on projects of varying sizes. During my career, I have noticed that many of the older software developers are burnt out. They would rather do their 9-5, get paid, and go home. They have little, if any, passion left, and I constantly wonder how they became this way. This contradicts my way of thinking; I consider myself to have some level of passion for what I do, and I enjoy going home knowing I made some kind of difference.

Needless to say, I think I am starting to see the effects of complacency. In my current job, I have a development manager who is difficult to deal with on a technical level. He possesses little technical knowledge of basic JavaEE concepts, nor has kept up on any programming in the last 10 years. There is a push from the upper echelon of the business to develop a new, more scalable system, but they don't realize that my manager is the bottleneck. Our team is constantly trying to get him to agree on software industry standards/best practices, but he doesn't get it and often times won't budge. I'm starting to feel the effects of becoming complacent. What is your advice?

Apple Locks iPhone 6/6+ NFC To Apple Pay Only 336

Posted by samzenpus from the pay-our-way dept.
Ronin Developer writes From the Cnet article: "At last week's Apple event, the company announced Apple Pay — a new mobile payments service that utilizes NFC technology in conjunction with its Touch ID fingerprint scanner for secure payments that can be made from the iPhone 6, iPhone 6 Plus or Apple Watch. Apple also announced a number of retailers that would accept Apple Pay for mobile payments at launch. However, Cult of Mac reports that NFC will be locked to the Apple Pay platform, meaning the technology will not be available for other uses. An Apple spokesperson confirmed the lock down of the technology, saying developers would be restricted from utilizing its NFC chip functionality for at least a year. Apple declined to comment on whether NFC capability would remain off limits beyond that period." So, it would appear, for at least a year, that Apple doesn't want competing mobile payment options to be available on the newly released iPhone 6 and 6+. While it's understandable that they want to promote their payment scheme and achieve a critical mass for Apple Pay, it's a strategy that may very well backfire as other other mobile payment vendors gain strength on competing platforms.
