Researchers Have Developed A Battery-Free Mobile Phone (hothardware.com) 83

An anonymous reader quotes HotHardware: Researchers from the University of Washington are looking to make batteries a thing of the past when it comes to mobile phones. The team has developed a phone that uses "almost zero power" according to associate professor Shyam Gollakota, who co-authored a paper which detailed the breakthrough... The researchers designed the phone to harvest microwatts of power from RF signals transmitted from a base station that is 31 feet away. Additional power is harnessed via ambient light through the use of miniature photodiodes that are about the size of a grain of rice. While in use, the phone consumes about 3.5 microwatts of power and is capable of communicating with a custom base station that is up to 50 feet away to send and receive calls... The phone ditches the traditional analog-to-digital converter, which turns your voice into data, in favor of a system that uses the vibrations from a microphone or speaker to perform the same task. An antenna then converts that motion into radio signals in such a way that very little power is consumed.
There's two drawbacks. First, modern smartphones "need a lot more than a 3.5-microwatt power budget for blazing fast processor, copious amounts of RAM and internal storage, and power-hungry displays." And more importantly, "you have to press a button to switch between transmissions and listening modes with the phone."

Bruce Perens Warns Grsecurity Breaches the Linux Kernel's GPL License (perens.com) 474

Bruce Perens co-founded the Open Source Initiative with Eric Raymond. Now he's sharing a "strong opinion" that companies should avoid the Grsecurity security patch for the Linux kernel "because it presents a contributory infringement and breach of contract risk." Slashdot reader NewGnu shared Bruce's comments: [I]t would fail a fair-use test... Because of its strongly derivative nature of the kernel, it must be under the GPL version 2 license, or a license compatible with the GPL and with terms no more restrictive than the GPL. Earlier versions were distributed under GPL version 2... My understanding from several reliable sources is that customers are verbally or otherwise warned that if they redistribute the Grsecurity patch, as would be their right under the GPL, that they will be assessed a penalty: they will no longer be allowed to be customers, and will not be granted access to any further versions of Grsecurity. GPL version 2 section 6 explicitly prohibits the addition of terms such as this redistribution prohibition...

This is tantamount to the addition of a term to the GPL prohibiting distribution or creating a penalty for distribution. GPL section 6 specifically prohibits any addition of terms. Thus, the GPL license, which allows Grsecurity to create its derivative work of the Linux kernel, terminates, and the copyright of the Linux Kernel is infringed. The contract from the Linux kernel developers to both Grsecurity and the customer which is inherent in the GPL is breached.

Perens advises companies to discuss his position with their attorneys, adding "In the public interest, I am willing to discuss this issue with companies and their legal counsel, under NDA, without charge."

Waymo Drops All But One Patent Claim Against Uber (fortune.com) 21

Google's Waymo has dismissed three of its four patent-infringement claims against Uber. An anonymous reader quotes Fortune: This comes after Waymo was encouraged to drop the claims following U.S. District Judge William Alsup's request that both parties narrow their issues for the trial. Additionally, Waymo dropped all but one of the patent claims because Uber abandoned its "Spider" LiDAR design, which had reportedly infringed upon the Waymo patents. The fourth patent claim, however, relates to a LiDAR design called, "Fuji," that the ride-hailing giant continues to use, according to Bloomberg...

In a statement to Fortune, a Waymo spokesperson said, "We found after fighting for discovery a device created by Anthony Levandowski at Uber that infringed Waymo patents. Uber has assured the court in statements made under penalty of perjury that it no longer uses and will not use that device, so we have narrowed the issues for trial by dismissing the patent claims as to that device, with the right to re-file suit if needed." The spokesman added, "We continue to pursue a patent claim against Uber's current generation device and our trade secret claims, which are not at all affected by this stipulated dismissal. We look forward to trial."

Uber called Waymo's move "yet another sign that they have overpromised and can't deliver. Not only have they uncovered zero evidence of any of the 14,000 files in question coming to Uber, they now admit that Uber's LiDAR design is actually very different than theirs.

Group Files FCC Motion To Delay Net Neutrality Proceedings (thehill.com) 46

"A public interest group wants the Federal Communications Commission to hold off on its proposal to kill net neutrality regulations," according to The Hill. An anonymous reader quotes their report: The National Hispanic Media Coalition (NHMC) filed a motion on Friday to delay the FCC's proceeding to undo its net neutrality rules, pending the release of documents the group has requested from the agency. The NHMC says it filed a request under the Freedom of Information Act for consumer complaints about the open internet since the net neutrality rules went into place in 2015. Carmen Scurato, the group's director of legal affairs, said that the requested documents will affect the public's view of the rules... "Millions of consumers have voiced their concerns about eliminating net neutrality protections and the agency should release all complaints that members of the public have submitted showing how the Open Internet Order has served as a tool in protecting our consumer rights."
"The FCC has confirmed that there is an overwhelming amount of responsive documents, therefore the disclosure of this information must be paired with sufficient time for members of the public to review and contribute meaningful input..." the group said in a statement. "To date, the FCC has only released a small fraction of the documents requested. This is a clear indication that the FCC must delay its Net Neutrality proceeding until all documents requested by NHMC are released. The FCC must then provide NHMC and members of the public adequate time to review and comment on this information before moving forward with its Net Neutrality proceeding."

An FCC spokesman was not immediately available for comment.

Survey Finds Most Popular Linux Laptop Distros: Ubuntu and Arch (phoronix.com) 141

After collating 30,171 responses, Phoronixhas released some results from their first Linux Laptop Survey. An anonymous reader quotes their report: To little surprise, Ubuntu was the most popular Linux distribution running on the respondents' laptops. 38.9% of the respondents were said to be using Ubuntu while interesting in second place was Arch Linux at 27.1% followed by Debian at 15.3%. Rounding out the top ten were then Fedora at 14.8%, Linux Mint in 5th at 10.8%, openSUSE/SUSE in sixth at 4.2%, Gentoo in seventh at 3.9%, CentOS/RHEL in eighth at 3.1%, Solus in ninth at 2%, and Manjaro in tenth at 1.6%. The other Linux distributions had each commanded less than 1% of the overall response.
Only 10.3% of respondents said their most recent laptop purchase came pre-loaded with Linux. But 29.3% are now dual-booting their Linux laptop with Windows, while another 4.4% were dual-booting with yet another Linux distribution.

Silicon Valley's Latest Desperate Housing Idea: On A Landfill (siliconvalley.com) 186

An anonymous reader writes: Silicon Valley real estate developers want to construct a $6.7 billion housing complex over a former landfill with 5.5 million tons of municipal waste from the last 25 years. "The regulators were pretty skeptical at the start, I have to say," one of the firm's partners told a local newspaper. Besides the 1,680 units of housing, there'd also be 700 hotel rooms, plus 5.7 million square feet of office space, and 1.1 million square feet for retail stores. The project "includes elaborate safety systems to block the escape of combustible methane gas and other dangerous vapors, and to prevent groundwater contamination," according to the Bay Area Newsgroup -- including one foot of solid concrete over 30 acres of landfill, with the housing built above the first-floor shops and parking structures "as a way of creating additional distance between residents and any escaped gases in the event of an emergency." In addition, there's alarms and sensors, "as well as another system to monitor, collect and dispose of gases underground."

Though the project has gained key approvals from the city of Santa Clara, it could still take two decades to complete. "Last year, the City of San Jose sued the City of Santa Clara, charging that the imbalance between the project's jobs and housing -- 23,000 jobs and 1,680 housing units -- will increase housing demand in San Jose and tax its overstretched services and infrastructure... but both sides said they hope for an out-of-court resolution."

FSF Sees Hopeful Signs Before Sunday's 'Day Against DRM' (defectivebydesign.org) 124

The Free Software Foundation's anti-DRM initiative "Defective By Design" argues that since last year's annual Day Against DRM, "we've seen cracks appearing in the foundation of the DRM status quo." The companies that profit from Digital Restrictions Management are still trying to expand the system of law and technology that weakens our security and curtails our rights, in an effort to prop up their exploitative business models. But since the last International Day Against DRM, the TPP trade agreement -- a key pro-DRM initiative -- crashed and burned. And our allies at the Electronic Frontier Foundation brought major legal and regulatory challenges against DRM in Washington DC... If we play our cards right, this may be the beginning of the end of DRM.

On Sunday, July 9, 2017, we will channel this momentum into the International Day Against DRM. We'll be gathering, protesting, and making -- showing the world that we insist on a future without Digital Restrictions Management. Will you join us? Here's what you can do now:

They're asking supporters to plan a protest, translate their fliers into more languages, voice support in videos and blog posts, or make endorsements. And you can also join the "DRM Elimination crew" mailing list or their Freenode IRC channel #dbd for year-round conversation and collaboration with the anti-DRM movement -- or simply make a donation to show your support.

Google's New Startup Heats Your Home With Energy From Your Lawn (cnn.com) 168

WindBourne shares an article about Google's plans for "an extremely cheap form of HVAC." CNN reports: A new startup called Dandelion, born from the secretive and futuristic lab "X" of Google's parent company Alphabet, says it will offer affordable geothermal heating and cooling systems to homeowners. Existing systems are typically expensive with big upfront installation fees, discouraging homeowners from adopting the technology... Installing the pipes -- called "ground loops" -- under someone's lawn is a traditionally invasive, messy process. It involves using wide drills that dig wells more than 1,000 feet underground. Dandelion's drill is fast and lean, allowing for only one or two deep holes a few inches wide. The system will cost between $20,000 and $25,000, compared to conventional systems priced as high as $60,000.

Geothermal systems are better for the environment because they significantly cut down on carbon dioxide emissions... Buildings are responsible for 39% of carbon dioxide emissions in the U.S., according to the U.S. Green Building Council. Most of these emissions come from the combustion of fossil fuels to provide the building with heating, cooling and lighting, and to power appliances and electrical equipment.

Google has been studying the potential of geothermal energy since 2011. Dandelion will eventually partner with local companies to handle installations -- and is already accepting sign-ups from customers in New York.

48-Year-Old Multics Operating System Resurrected (multicians.org) 94

"The seminal operating system Multics has been reborn," writes Slashdot reader doon386: The last native Multics system was shut down in 2000. After more than a dozen years in hibernation a simulator for the Honeywell DPS-8/M CPU was finally realized and, consequently, Multics found new life... Along with the simulator an accompanying new release of Multics -- MR12.6 -- has been created and made available. MR12.6 contains many bug and Y2K fixes and allows Multics to run in a post-Y2K, internet-enabled world.
Besides supporting dates in the 21st century, it offers mail and send_message functionality, and can even simulate tape and disk I/O. (And yes, someone has already installed Multics on a Raspberry Pi.) Version 1.0 of the simulator was released Saturday, and Multicians.org is offering a complete QuickStart installation package with software, compilers, install scripts, and several initial projects (including SysDaemon, SysAdmin, and Daemon). Plus there's also useful Wiki documents about how to get started, noting that Multics emulation runs on Linux, macOS, Windows, and Raspian systems.

The original submission points out that "This revival of Multics allows hobbyists, researchers and students the chance to experience first hand the system that inspired UNIX."

Ask Slashdot: How Safe, Really, Is Paying For Things Online? 396

An anonymous reader writes: Due to the rash of intrusions into electronic payment systems lately, I've decided to go back to paying cash for everyday purchases, groceries, fuel, and anything else I pay for in person (which also has the positive effect of making balacing my checkbook every month that much easier). The question I have is: For the monthly bills it's just not practical to pay in person (utilities, for instance), how safe are those?

Five minutes of research is telling me that mailing paper checks isn't any more secure than online electronic payments and in fact may be even less secure, but short of literally showing up at the electric company, phone company, ISP, and so on, and paying them cash in person, I can't see any other way to pay them. So how safe is it right now, honestly?

I'm always interested in how Slashdot readers secure their own personal finances -- but how high is the danger that a remote malefactor will hijack and then drain your bank account? Leave your best answers in the comments. How safe, really, is paying for things online?

Nest Founder 'Wakes Up In Cold Sweats' Fearing The Impact Of Mobile Technology (fastcodesign.com) 106

theodp writes: Fast Company's Co.Design reports that Tony Fadell, who founded Nest and was instrumental in the creation of the iPod and iPhone, spoke with a mix of pride and regret about his role in mobile technology's rise to omnipresence. "I wake up in cold sweats every so often thinking, what did we bring to the world?" Fadell said. "Did we really bring a nuclear bomb with information that can -- like we see with fake news -- blow up people's brains and reprogram them? Or did we bring light to people who never had information, who can now be empowered?"

Faddell added that addiction has been designed into our devices, and it's harming the newest generation. "And I know when I take [technology] away from my kids what happens," Fadell explained. "They literally feel like you're tearing a piece of their person away from them-they get emotional about it, very emotional. They go through withdrawal for two to three days." Products like the iPhone, Fadell believes, are more attuned to the needs of the individual rather than what's best for the family and the larger community. And pointing to YouTube owner Google, Fadell said, "It was like, [let] any kind of content happen on YouTube. Then a lot of the executives started having kids, [and saying], maybe this isn't such a good idea. They have YouTube Kids now."

The article suggests Fadell is describing a world where omnipresent (and distracting) screens are creating "a culture of self-aggrandizement," and he believes this is partly rooted in the origins of the devices. "A lot of the designers and coders who were in their 20s when we were creating these things didn't have kids."

John McAfee Can Finally Use His Own Name Again (fossbytes.com) 52

An anonymous reader quotes Fossbytes: It was last year when, John McAfee, the co-founder of an antivirus company that's now owned by Intel, took Intel to the court over the right to use his name for commercial purposes... According to a Reuters report, the US District Judge Paul Oetken has dismissed the 2016 case and the counter lawsuit filed by Intel. The two parties have settled upon a mutual agreement which allows John Mcafee to use his name for promotions, presentations, and advertisements. He can't link his name to any product or service related to cyber security and security.
McAfee told the BBC that he can't directly name a company after himself, adding "I can live with that. That certainly beats having to live with 'The Entrepreneur Formerly known as McAfee.'"

Johnny Depp is still scheduled to play McAfee in a movie called "King of the Jungle," which will focus on the period of his life when McAfee fled a police investigation in Belize.

Microsoft's Last 'Bug Bash' Before Windows 10 Fall Creators Update (betanews.com) 80

Mark Wilson quotes BetaNews: With the launch of Windows 10 Fall Creators Update Build 16237 to the Fast Ring yesterday, Microsoft wheeled in numerous fixes and new features. At the same time, the company also announced that the second Bug Bash for the next big update to Windows 10 is about to take place. This is the last Bug Bash that will take place before the release of the final version of Windows 10 Fall Creators Update, and it will see an intense period of testing with the help of Windows Insiders. Things kick off on Friday, July 14 and continue for more than a week.

Of course, the whole idea of the insider program is to help Microsoft to home in on bugs and get them fixed before software is released to the masses, but the Bug Bash steps things up a notch. Participants will be asked to take part in quests to check specific elements of the operating system as Microsoft draws closer to pushing out this latest feature update.

This build includes "read out loud" functionality for PDFs, support for emoji 5.0 -- and now when you relaunch Edge after it crashes, your tabs will be restored automatically.

Google Funds A Team Of Robot Journalists (theguardian.com) 43

Darren Sharp brings news about the arrival of robot journalists. The Guardian reports: Robots will help a national news agency to create up to 30,000 local news stories a month, with the help of human journalists and funded by a Google grant. The Press Association has won a €706,000 ($800,779 or £621,000) grant to run a news service with computers writing localised news stories. The national news agency, which supplies copy to news outlets in the U.K. and Ireland, has teamed up with data-driven news start-up Urbs Media for the project, which aims to create "a stream of compelling local stories for hundreds of media outlets"... PA's editor-in-chief, Peter Clifton, said journalists will still be involved in spotting and creating stories and will use artificial intelligence to increase the amount of content. He said: "Skilled human journalists will still be vital in the process, but Radar [the Reporters And Data And Robots project] allows us to harness artificial intelligence to scale up to a volume of local stories that would be impossible to provide manually." Journalists will create "detailed story templates" for articles about crime, health, and employment, for example, then use natural language software to create multiple versions to "scale up the mass localization."

Enthusiast Resurrects IBM's Legendary 'Model F' Keyboard (popularmechanics.com) 184

An anonymous reader quotes Popular Mechanics: You may not know the Model F by name, but you know it by sound -- the musical thwacking of flippers slapping away. The sound of the '80s office. The IBM Model F greeting the world in 1981 with a good ten pounds of die-cast zinc and keys that crash down on buckling metal springs as they descend. It's a sensation today's clickiest keyboards chase, but will never catch. And now it's coming back. The second coming of the high-quality Model F (not to be confused with its more affordable plastic successor, the Model M) isn't a throwback attention grab from IBM, nor a nostalgia play from Big Keyboard. Instead, it's the longtime work of a historian in love with the retro keyboard's unparalleled sound and feel, but frustrated by the limitations of actual decades-old tech.

The Model F Keyboards project, now taking preorders for the new line of authentic retro-boards, was started by Joe Strandberg, a Cornell University grad who's taken up keyboard wizardry as a nights-and-weekends hobby. He started as a collector and restorer of genuine Model F keyboards -- originally produced from 1981 to 1994 -- a process that familiarized him with their virtues and their flaws... Working with a factory in China, Strandberg has carefully overseen the reproduction process one step at time, from the springs to the unique powder-coating on the keyboard's zinc case. Despite the expense (Strandberg estimates spending $100,000 to revive the tooling necessary for the production run), it was the only viable option given the kind of abuse your average keyboard takes on a daily basis. "With 3D printing," he says, "the keyboard wouldn't last a year."

The first prototypes have just left the assembly line, and he's already racked up over a quarter of a million dollars in pre-orders. Does anyone else fondly remember IBM's hefty and trusty old keyboards?
