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.

Gilbert, AZ Censors Biology Books the Old-Fashioned Way 289

nbauman writes The Gilbert, AZ school board has voted to tear out a page from Campbell's Biology (a standard highly-recommended textbook that many doctors and scientists fondly remember), because it discusses contraception without also discussing adoption. Julie Smith, a member of the Gilbert Public Schools governing board, said that she was a Catholic and "we do not contracept." Smith convinced the board that Campbell's violates Arizona law to teach "preference, encouragement and support to childbirth and adoption" over abortion. The Arizona Education Department decided that the pages didn't violate Arizona law, but nevermind. Rachel Maddow generously risked hassles for copyright violation and posted the missing pages as a service to Arizona honors biology students.

333 Km/h Rocket-Powered Bicycle Sets New Speed Record 51

Dave Knott writes François Gissy of France has claimed a new bicycle speed record. As you might guess, he was not pedalling – he was seated atop a hydrogen peroxide-powered rocket with three thrusters fastened to the frame of an elongated, but otherwise ordinary-looking bicycle. In a video posted on YouTube that announces the record, a Ferrari racing the bike is left far behind within seconds of leaving the starting line. The bike, designed by Gissy's friend, Arnold Neracher, reached its top speed of 333 km/h (207mph) in just 4.8 seconds and 250 metres. According to Guinness World Records, the fastest speed ever for a bicycle that wasn't rocket powered was 268.831 km/h by Fred Rompelberg of the Netherlands, riding behind a wind-shield fitted dragster in 1995 and assisted by the slipstream of the car. The current unassisted bicycle speed record is 133.8 km/h — a record that a team in Toronto is trying to break.

Most Planets In the Universe Are Homeless 219

StartsWithABang writes: We like to think of our Solar System as typical: a central star with a number of planets — some gas giants and some rocky worlds — in orbit around it. Yes, there's some variety, with binary or trinary star systems and huge variance in the masses of the central star being common ones, but from a planetary point of view, our Solar System is a rarity. Even though there are hundreds of billions of stars in our galaxy for planets to orbit, there are most likely around a quadrillion planets in our galaxy, total, with only a few trillion of them orbiting stars at most. Now that we've finally detected the first of these, we have an excellent idea that this picture is the correct one: most planets in the Universe are homeless. Now, thank your lucky star!"

Yes. They introduced a thing several months (maybe a year now) ago which gives you five inboxes instead of one. There's one for Social that catches all the stupid emails social networking things send you. There's one for Promotions that catches commercial email (at least, whatever isn't spam-boxed instead). There's one poorly defined one called Updates which is supposed to be for receipts, statements, bills, and confirmations - email related to stuff you bought or business you are involved in, as opposed to Store X's weekly email which is in promotions. And one for Forums is meant to be email from mailing lists. There is also the Primary inbox for everything else, which is meant to be just the real email from friends and such after everything else goes into the other boxes.

This never worked well. The social filter is pretty good. But I am on one mailing list which ends up in Promotions about 2/3 of the time, despite my repeatedly telling GMail to deliver it to Forums instead, and despite the mailing list having no commercial content whatsoever. The filter for Updates is really whacked; anything can end up in here, and the stuff that should go here can end up in Forums, Promotions, or Primary instead.

The new thing sounds similar, but on steroids. More like using labels (which are GMail's equivalent of folders to file email into, except that emails can have more than one label and so the folders aren't exclusive), but letting Google determine the labels by itself. We'll see how good that works.

Symantec To Separate Into Two Companies 86

Posted by samzenpus
from the split-up dept.
wiredmikey writes Symantec announced plans on Thursday to split into two separate, publicly traded companies – one focused on security, the other focused on information management. The company's security business generated $4.2 billion in revenue in fiscal year 2014 while its information management business meanwhile hit revenues of $2.5 billion. "As the security and storage industries continue to change at an accelerating pace, Symantec's security and IM businesses each face unique market opportunities and challenges," Symantec CEO Michael A. Brown, who officially took over as CEO last month, said in a statement. Garrett Bekker, senior analyst with 451 Research, called the decision "long overdue." "The company had become too big to manage, and they were having trouble keeping up with the pace of innovation in many areas of security," he told SecurityWeek. "The synergies between storage and security never really emerged, in part because in many firms, particularly large enterprises, they are managed by different internal teams."

Breakthrough In LED Construction Increases Efficiency By 57 Percent 182

Zothecula writes: With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent.

The first story about "on a computer" patents getting invalidated is a good thing. But the second story is perhaps even more important. People are taking notice that patent examiners are not doing their jobs. Too many of them are just working one day a week/month/whatever and just rubberstamping their quota of patents, allowing anything whatsoever through the system, and falsely reporting that they worked full time and even overtime, because there is a corrupt culture that lets them get away with it. Exposing this could lead to mass firings, and some sort of system to ensure real accountability.

It's a problem, though, because there's no simple metric to determine whether patent examiners are doing a good job. Using number of patents reviewed as that metric encourages examiners to do a shoddy job actually examining the patents (i.e. what has actually been happening). If they are expected to pass only a certain fraction of patents, this is slightly better since it forces them to actually come up with reasons to reject some patents, but what fraction should they use? Two examiners doing perfect jobs may have very different fractions of accepted patents simply because one got better patents to review than the other, especially if they have different focus areas. Does the patent office even know the fraction of submitted patents in various areas which are good? A better metric would be whether accepted patents survive in the courts, but this depends on somebody actually challenging the patents and takes years after the fact. It might help now throw out some of the patent examiners who clearly haven't been doing their jobs in the past.

I'm not sure what the right solution is. Blind peer review and multiple review? Assign each patent to 2 or 3 different reviewers and call to carpet the ones who most consistently differ from others? Does that even work if half your patent examiners are shirking?


Mozilla Rolls Out Sponsored Tiles To Firefox Nightly's New Tab Page 171

An anonymous reader writes Mozilla has rolled out directory tiles, the company's advertising experiment for its browser's new tab page, to the Firefox Nightly channel. We installed the latest browser build to give the sponsored ads a test drive. When you first launch Firefox, a message on the new tab page informs you of the following: what tiles are (with a link to a support page about how sponsored tiles work), a promise that the feature abides by the Mozilla Privacy Policy, and a reminder that you can turn tiles off completely and choose to have a blank new tab page. It's quite a lot to take in all at once.

Finding an ISIS Training Camp Using Google Earth 134

An anonymous reader writes: Terrorist organization ISIS has been in the news a lot lately for their hostile activities in Iraq and Syria. They've also been very active online, posting propaganda and photos on various social networking sites to try to recruit more members. Frequently, they'll have pictures of themselves in nondescript locations — but even carefully selected images give clues to a real location. Citizen journalists at Bellingcat analyzed a group of these photos, comparing buildings and bridges in the background to images from Google Earth. With very little to go on, they were able to pinpoint the location of a terrorist training camp.

About 4 or 5 years ago, all the broadcast TV in the US changed over to a digital format, and the digital format includes HDTV broadcasts. If you have an HDTV and an antenna, and you live in a place where you can receive the signals, you can get the HDTV of all the broadcast networks over the air (OTA) with no cable.

It has been reported that Comcast re-compresses the digital HDTV streams, cramming them into a smaller digital channel in their cable system, in order to fit more channels in. This leads to reduced quality in the picture you view on Comcast compared to the OTA HDTV broadcast. I don't know about other cable systems. Here is one such report, though it seems to be specifically about other non-OTA HD channels (where the FIOS broadcast was used for comparison).


Philips Ethernet-Powered Lighting Transmits Data To Mobile Devices Via Light 104

llebeel writes Philips has shown off its Ethernet-powered connected lighting, which can transmit data to mobile devices through light via embedded code. Arriving in the form of LED "luminaires," Philips' connected office lighting will aim to not only save businesses money on energy costs, but also serve as a means of providing information and data about the general running of a building, transmitted through light, to improve the overall efficiency of business infrastructure. Philips' Onno Willemse said, "Over the light, we can project a code — its number, its IP address, its MAC address — making each fixture unique and recognizable. We can also receive that light on our mobile phones, so if you hold the lens of a mobile device under the luminaire, it actually reads the code and makes a connection to it over WiFi."

Krebs on Microsoft Suspending "Patch Tuesday" Emails and Blaming Canada 130

tsu doh nimh writes In a move that may wind up helping spammers, Microsoft is blaming a new Canadian anti-spam law for the company's recent decision to stop sending regular emails about security updates for its Windows operating system and other Microsoft software. Some anti-spam experts who worked very closely on Canada's Anti-Spam Law (CASL) say they are baffled by Microsoft's response to a law which has been almost a decade in the making. Indeed, an exception in the law says it does not apply to commercial electronic messages that solely provide "warranty information, product recall information or safety or security information about a product, goods or a service that the person to whom the message is sent uses, has used or has purchased." Several people have observed that Microsoft likely is using the law as a convenient excuse for dumping an expensive delivery channel.

Draper Labs Develops Low Cost Probe To Orbit, Land On Europa For NASA 79

Posted by samzenpus
from the heading-out dept.
MarkWhittington writes Ever since the House passed a NASA spending bill that allocated $100 million for a probe to Jupiter's moon Europa, the space agency has been attempting to find a way to do such a mission on the cheap. The trick is that the mission has to cost less than $1 billion, a tall order for anything headed to the Outer Planets. According to a Wednesday story in the Atlantic, some researchers at Draper Labs have come up with a cheap way to do a Europa orbiter and land instruments on its icy surface.

The first stage is to orbit a cubesat, a tiny, coffee can sized satellite that would contain two highly accurate accelerometers that would go into orbit around Europa and measure its gravity field. In this way the location of Europa's subsurface oceans would be mapped. Indeed it is possible that the probe might find an opening through the ice crust to the ocean, warmed it is thought by tidal forces.

The second stage is to deploy even smaller probes called chipsats, tiny devices that contain sensors, a microchip, and an antenna. Hundreds of these probes, the size of human fingernails, would float down on Europa's atmosphere to be scattered about its surface. While some might be lost, enough will land over a wide enough area to do an extensive chemical analysis of the surface of Europa, which would then be transmitted to the cubesat mothership and then beamed to Earth.
