fstack writes: Pi Day was marked this year by the launch of the Raspberry Pi 3 Model B+ as the next evolution to this $35 ARM single-board computer. Phoronix has now put out Raspberry Pi 3 B+ benchmarks showing that the Ethernet performance is indeed much faster now but still doesn't stack up to other high performance boards, the SoC temperature is noticeably lower than the very warm Raspberry Pi 3, and the overall performance is a nice upgrade while retaining the same price point as its predecessors. Follow up tests looking at the Wi-Fi performance also show the new 802.11ac dual-band wireless to be much faster as well.

Facebook has had a terrible week. Since it was revealed that political data firm Cambridge Analytica obtained information about 50 million Facebook users, the social media company has been in damage control mode, apologizing for its mistakes and conducting forensic audits to determine exactly what happened. SFGate reports today that Facebook "has been hit with four lawsuits in federal court in San Francisco and San Jose thus far this week." From the report: One lawsuit was filed by a Facebook user who claims the Menlo Park company acted with "absolute disregard" for her personal information after allegedly representing that it wouldn't disclose the data without permission or notice. That lawsuit, filed by Lauren Price of Maryland in San Jose on Tuesday, seeks to be a class action on behalf of up to 50 million people whose data was allegedly collected from Facebook by London-based Cambridge Analytica. The lawsuit says that during the 2016 election, Price was "frequently targeted with political ads while using Facebook." It seeks financial restitution for claims of unfair business practices and negligence. Both Facebook and Cambridge Analytica are named as defendants. Cambridge Analytica also announced today that the company will undergo an independent third-party audit to determine whether it still holds any data covertly obtained from Facebook users. "We take the disturbing recent allegations of unethical practices in our non-U.S. political business very seriously," CEO Alexander Tayler writes. "The Board has launched a full and independent investigation into SCL Elections' past practices, and its findings will be shared publicly."

UPDATE: Eighteen enforcement officers have entered the Cambridge Analytica headquarters in London's West End to search the premises after the data watchdog was granted a warrant to examine its records, reports The Guardian.

"In 2014, Facebook bought WhatsApp for $16 billion, making its co-founders -- Jan Koum and Brian Acton -- very wealthy men," reports The Verge. "Koum continues to lead the company, but Acton quit earlier this year to start his own foundation." Today, Acton told his followers on Twitter to delete Facebook. From the report: "It is time," Acton wrote, adding the hashtag #deletefacebook. Acton, who is worth $6.5 billion, did not immediately respond to a request for comment. Nor did Facebook and WhatsApp. It was unclear whether Acton's feelings about Facebook extend to his own app. But last month, Acton invested $50 million into Signal, an independent alternative to WhatsApp. The tweet came after a bruising five-day period for Facebook that has seen regulators swarm and its stock price plunge following concerns over data privacy in the wake of revelations about Cambridge Analytica's misuse of user data. Acton isn't the only one taking to Twitter to announce their breakup with Facebook. The #DeleteFacebook movement is gaining steam following the New York Times' report about how the data of 50 million users had been unknowingly leaked and purchased to aid President Trump's successful 2016 bid for the presidency. For many users, the news "highlighted the danger of Facebook housing the personal information of billions of users," reports SFGate. "And even before the Cambridge Analytica news, Facebook has been grappling with its waning popularity in the U.S. The company lost 1 million domestic users last quarter -- its first quarterly drop in daily users."

An anonymous reader quotes a report from Ars Technica: The chief of the Tempe Police has told the San Francisco Chronicle that Uber is likely not responsible for the Sunday evening crash that killed 49-year-old pedestrian Elaine Herzberg. "I suspect preliminarily it appears that the Uber would likely not be at fault in this accident," said Chief Sylvia Moir. Herzberg was "pushing a bicycle laden with plastic shopping bags," according to the Chronicle's Carolyn Said, when she "abruptly walked from a center median into a lane of traffic." After viewing video captured by the Uber vehicle, Moir concluded that "it's very clear it would have been difficult to avoid this collision in any kind of mode (autonomous or human-driven) based on how she came from the shadows right into the roadway." Moir added that "it is dangerous to cross roadways in the evening hour when well-illuminated, managed crosswalks are available." The police said that the vehicle was traveling 38 miles per hour in a 35 mile-per-hour zone, according to the Chronicle -- though a Google Street View shot of the roadway taken last July shows a speed limit of 45 miles per hour along that stretch of road.

Slashdot reader bricko shares an article from Scientific American about two "ecomodernists" who argue that the problems of climate change can be addressed through science and technology. In his Breakthrough essay, Steven Pinker spells out a key assumption of ecomodernism. Industrialization "has been good for humanity. It has fed billions, doubled lifespans, slashed extreme poverty, and, by replacing muscle with machinery, made it easier to end slavery, emancipate women, and educate children. It has allowed people to read at night, live where they want, stay warm in winter, see the world, and multiply human contact. Any costs in pollution and habitat loss have to be weighed against these gifts...."

We can solve problems related to climate change, Pinker argues, "if we sustain the benevolent forces of modernity that have allowed us to solve problems so far, including societal prosperity, wisely regulated markets, international governance, and investments in science and technology... Since 1970, when the Environmental Protection Agency was established, the United States has slashed its emissions of five air pollutants by almost two-thirds. Over the same period, the population grew by more than 40 percent, and those people drove twice as many miles and became two and a half times richer. Energy use has leveled off, and even carbon dioxide emissions have turned a corner."
The essay also cites ecomodernist Will Boisvert, who believes climate change will be cataclysmic but not apocalyptic, bringing large upheaval but a small impact on human well-being. "Global warming won't wipe us out or even stall our progress, it will just marginally slow ordinary economic development that will still outpace the negative effects of warming and make life steadily better in the future, under every climate scenario.... Our logistic and technical capacities are burgeoning, and they give us ample means of addressing these problems."

Stack Overflow has released the results of its annual survey of 100,000 developers, revealing the most-popular, top-earning, and preferred programming languages. ArsTechnica: JavaScript remains the most widely used programming language among professional developers, making that six years at the top for the lingua franca of Web development. Other Web tech including HTML (#2 in the ranking), CSS (#3), and PHP (#9). Business-oriented languages were also in wide use, with SQL at #4, Java at #5, and C# at #8. Shell scripting made a surprising showing at #6 (having not shown up at all in past years, which suggests that the questions have changed year-to-year), Python appeared at #7, and systems programming stalwart C++ rounded out the top 10.

These aren't, however, the languages that developers necessarily want to use. Only three languages from the most-used top ten were in the most-loved list; Python (#3), JavaScript (#7), and C# (#8). For the third year running, that list was topped by Rust, the new systems programming language developed by Mozilla. Second on the list was Kotlin, which wasn't even in the top 20 last year. This new interest is likely due to Google's decision last year to bless the language as an official development language for Android. TypeScript, Microsoft's better JavaScript than JavaScript comes in at fourth, with Google's Go language coming in at fifth. Smalltalk, last year's second-most loved, is nowhere to be seen this time around. These languages may be well-liked, but it looks as if the big money is elsewhere. Globally, F# and OCaml are the top average earners, and in the US, Erlang, Scala, and OCaml are the ones to aim for. Visual Basic 6, Cobol, and CoffeeScript were the top three most-dreaded, which is news that will surprise nobody who is still maintaining Visual Basic 6 applications thousands of years after they were originally written.

Microsoft languages seem to be hitting the right note with coders across ops, data science, and app development. From a report: JavaScript remains the most popular programming language, but two offerings from Microsoft are steadily gaining, according to developer-focused analyst firm RedMonk's first quarter 2018 ranking. RedMonk's rankings are based on pull requests in GitHub, as well as an approximate count of how many times a language is tagged on developer knowledge-sharing site Stack Overflow. Based on these figures, RedMonk analyst Stephen O'Grady reckons JavaScript is the most popular language today as it was last year. In fact, nothing has changed in RedMonk's top 10 list with the exception of Apple's Swift rising to join its predecessor, Objective C, in 10th place. The top 10 programming languages in descending order are JavaScript, Java, Python, C#, C++, CSS, Ruby, and C, with Swift and Objective-C in tenth.

TIOBE's top programming language index for March consists of many of the same top 10 languages though in a different order, with Java in top spot, followed by C, C++, Python, C#, Visual Basic .NET, PHP, JavaScript, Ruby, and SQL. These and other popularity rankings are meant to help developers see which skills they should be developing. Outside the RedMonk top 10, O'Grady highlights a few notable changes, including an apparent flattening-out in the rapid ascent of Google's back-end system language, Go.

The New York Times notes an important caveat to Florida's recently-approved law observing daylight savings time year-round: it specifies that their change will only go into effect if "the United States Congress amends 15 U.S.C. s. 260a to authorize states to observe daylight saving time year-round."

"In other words: Even if the governor signs the bill, nothing will happen now... States can choose to exempt themselves from daylight saving time -- Arizona and Hawaii do -- but nothing in federal law allows them to exempt themselves from standard time." Meanwhile one California legislator exploring the idea of year-round standard time discovered that "youth sports leagues and families worried that a year-round early sunset would shut down their kids' after-school games." But the Times also acknowledges problems in the current system. "In parts of Maine, for example, between Thanksgiving and Christmas, the sun sets before 4 p.m. -- more than an hour earlier than it does in Detroit, at the other end of the Eastern time zone." So is there a better alternative?

An anonymous reader quotes Business Insider: Standardtime.com has a unique suggestion. Their proposal has only two time zones in the continental U.S. that are two hours apart, which The Atlantic calls "a simple plan to fix [DST]"... Johns Hopkins University professors Richard Henry and Steven Hanke have come up with yet another possible fix: worldwide adoption of a single time zone. They argue that the internet has eliminated the need for discrete time zones across the globe, so we might as well just do away with them...

No plan will satisfy everyone. But that doesn't mean daylight-saving time is good. The absence of major energy-saving benefits from DST -- along with its death toll, health impacts, and economic ramifications -- are reason enough to get rid of the ritual altogether.
The article associates Daylight Saving Time with "a spike in heart attacks, increased numbers of work injuries, automobile accidents, suicides, and more." And in addition, it also blames DST for an increased use of gasoline and air conditioners -- adding that it will also "rob humanity of billions of hours of sleep like an evil spacetime vampire."

An anonymous reader quotes Debian.org: The Debian project is pleased to announce the fourth update of its stable distribution Debian 9 (codename "stretch"). This point release mainly adds corrections for security issues, along with a few adjustments for serious problems... Please note that the point release does not constitute a new version of Debian 9 but only updates some of the packages included. There is no need to throw away old "stretch" media. After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror.
Phoronix adds that Debian 9.4 "has a new upstream Linux kernel release, various dependency fixes for some packages, an infinite loop fix in Glade, several CVE security fixes, a larger stack size for NTP, a new upstream release of their NVIDIA proprietary driver package, Python 3 dependency fixes, and other security fixes."

An anonymous reader quotes Ars Technica: A major dust-up on an Internet discussion forum is touching off troubling questions about the security of some browser-trusted HTTPS certificates when it revealed the CEO of a certificate reseller emailed a partner the sensitive private keys for 23,000 TLS certificates. The email was sent on Tuesday by the CEO of Trustico, a UK-based reseller of TLS certificates issued by the browser-trusted certificate authorities Comodo and, until recently, Symantec...

In communications earlier this month, Trustico notified DigiCert that 50,000 Symantec-issued certificates Trustico had resold should be mass revoked because of security concerns. When Jeremy Rowley, an executive vice president at DigiCert, asked for proof the certificates were compromised, the Trustico CEO emailed the private keys of 23,000 certificates, according to an account posted to a Mozilla security policy forum. The report produced a collective gasp among many security practitioners who said it demonstrated a shockingly cavalier treatment of the digital certificates that form one of the most basic foundations of website security... In a statement, Trustico officials said the keys were recovered from "cold storage," a term that typically refers to offline storage systems. "Trustico allows customers to generate a Certificate Signing Request and Private Key during the ordering process," the statement read. "These Private Keys are stored in cold storage, for the purpose of revocation."
"There's no indication the email was encrypted," reports Ars Technica, and the next day DigiCert sent emails to Trustico's 23,000+ customers warning that their certificates were being revoked, according to Bleeping Computer.

In a related development, Thursday Trustico's web site went offline, "shortly after a website security expert disclosed a critical vulnerability on Twitter that appeared to make it possible for outsiders to run malicious code on Trustico servers."

A survey of satellite data published in the journal Cryosphere confirms what scientists have suspected for a while now: ice loss from the critical region of Antarctica is happening at an increasingly fast pace. Quartz reports: In total, researchers found that Antarctica lost roughly 1,929 gigatons of ice in 2015, which amounts to an increase of roughly 36 gigatons per year every year since 2008. (A gigaton is one billion tons.) Nearly 90% of that increase in loss occurred in West Antarctica, "probably in response to ocean warming," according to NASA. The new data analysis mostly confirms other recent research, but does so with a higher degree of precision by using a new technique that can process a larger amount of satellite data than was possible before.

West Antarctica has been losing a lot of ice in recent years, and at an ever-growing pace, while East Antarctica is losing ice more steadily. The West Antarctic ice sheet is of particular concern because, like a building that stands on an uneven foundation, it is inherently unstable, making it especially vulnerable to the warming climate. If the entire ice sheet were destabilized and melted into the sea, researchers estimate it would lead to 3 meters (9 feet) of sea level rise globally. Models suggest that under a low-emissions scenario, where the world commits to "peaking" and then steadily reducing emissions in the near future, complete destabilization of the West Antarctic ice sheet is possible to avoid. But under medium- or high-emissions scenarios, the loss of the ice sheet becomes inevitable.

hyperclocker shares a report from Popular Mechanics: The future of spacecraft in lower Earth orbit (LEO) looks to be an increasingly commercial affair. Bigelow Aerospace, a Las Vegas-based company that builds livable space habitats, has now created a spinoff company known as Bigelow Space Operations (BSO). BSO will market and operate any space habitats that Bigelow sells. The creation of BSO signals that Bigelow is preparing for a future of commercial space living. Recently leaked NASA documents show that the Trump Administration wants to convert the International Space Station into a commercial venture, and BSO is betting that businesses including private scientific ventures and hotels will be interested in creating a profit above the Earth. A prototype Bigelow habitat, the Bigelow Expandable Activity Module (BEAM), has been connected to the ISS since 2016. It's proven such a successful addition that last year NASA extended its contract for an additional three years. But Bigelow is thinking past the BEAM. In its press release announcing BSO, it highlights its planned launches of the B330-1 and B330-2, spacecraft with 6-person capacity, in 2021.

Since the latest graphics processing units (GPUs) are so popular with cryptocurrency miners, the SETI project -- short for "Search for Extraterrestrial Intelligence" -- can't find the graphics cards it needs to expand its operations. The SETI@home project helps provide some computing power, as it involves thousands of volunteers who turn the power of their computers over to the project, but it's only a portion of the SETI project's total computing power. Motherboard reports: Searching the stars is intense work that "uses radio telescopes to listen for narrow-bandwidth radio signals from space." Analyzing all of the data from these telescopes uses a lot of computing power. "We'd like to use the latest GPUs and we can't get 'em," Dan Werthimer, chief scientist of SETI, told the BBC. "That's limiting our search for extraterrestrials." Manufacturers such as Nvidia are struggling to keep up with demand for graphics cards. It recently told investors it would rise to meet its manufacturing challenge while focusing on its core market -- gamers. It even suggested vendors limit purchases of graphics cards from individual buyers in an effort to stop miners from buying up all the cards. "This is a new problem, it's only happened on orders we've been trying to make in the last couple of months," Werthimer told the BBC. "We've got the money, we've contacted the vendors, and they say, 'we just don't have them.'"

UPSat is the first open source -- both hardware and software -- satellite to have ever been launched in orbit. Pierros Papadeas, the Director of Operations for Libre Space Foundation, which helped build the UPSat, talked about the project at FOSDEM, a non-commercial, volunteer-organized European event focused on free and open-source software development. You can watch the talk here; and read an interview of him with folks at FOSDEM ahead of the talk here. Two excerpts from the interview: Q: What challenges did you encounter while designing, building, testing and eventually launching UPSat in orbit?
PP: The challenges where numerous, starting with the financial ones. Lack of appropriate funding led us to invest heavily in the project (through Libre Space Foundation funds) to ensure its successful completion. Countless volunteer participation was also key to the success. On the technical side, with minimal documentation and knowledge sharing around space projects we had to re-invent the wheel and discover many procedures and practices in a really short time-frame (6 months - unheard for a space mission). Lack of tools and equipment made our building process a creative exploration as we had to figure out ways to achieve specific tasks resorting to purpose-built projects in our local lab (hackerspace.gr). Testing and verification facilities where also a challenge mainly as we had to undergo much more extensive tests than other missions, having none of our components already "flight proven". Again creativity and countless hours of negotiations and documentation got us to the final delivery point. Launching UPSat in orbit was secured once the delivery happened, but as any typical space mission it came with long delays and timeline push-backs.

Q: What do you hope to accomplish by giving this talk? What do you expect?
Through this talk we would like to raise awareness for open source initiatives in space, and inspire open source technologists (engineers, programmers, analysts, makers) to engage in an open source project. We would also love to gather feedback and ideas on next steps and provide contribution opportunities for interested parties.

Today is the 20th anniversary of the phrase "open source software," which this article says was coined by the executive director of the Foresight Institute, a nonprofit think tank focused on nanotech and artificial intelligence. The phrase first entered the world on February 3rd, 1998, according to Christine Peterson: Of course, there are a number of accounts of the coining of the term, for example by Eric Raymond and Richard Stallman, yet this is mine, written on January 2, 2006. It has never been published, until today. The introduction of the term "open source software" was a deliberate effort to make this field of endeavor more understandable to newcomers and to business, which was viewed as necessary to its spread to a broader community of users... Interest in free software was starting to grow outside the programming community, and it was increasingly clear that an opportunity was coming to change the world... [W]e discussed the need for a new term due to the confusion factor. The argument was as follows: those new to the term "free software" assume it is referring to the price. Oldtimers must then launch into an explanation, usually given as follows: "We mean free as in freedom, not free as in beer." At this point, a discussion on software has turned into one about the price of an alcoholic beverage...

Between meetings that week, I was still focused on the need for a better name and came up with the term "open source software." While not ideal, it struck me as good enough. I ran it by at least four others: Eric Drexler, Mark Miller, and Todd Anderson liked it, while a friend in marketing and public relations felt the term "open" had been overused and abused and believed we could do better. He was right in theory; however, I didn't have a better idea... Later that week, on February 5, 1998, a group was assembled at VA Research to brainstorm on strategy. Attending -- in addition to Eric Raymond, Todd, and me -- were Larry Augustin, Sam Ockman, and attending by phone, Jon "maddog" Hall... Todd was on the ball. Instead of making an assertion that the community should use this specific new term, he did something less directive -- a smart thing to do with this community of strong-willed individuals. He simply used the term in a sentence on another topic -- just dropped it into the conversation to see what happened.... A few minutes later, one of the others used the term, evidently without noticing, still discussing a topic other than terminology. Todd and I looked at each other out of the corners of our eyes to check: yes, we had both noticed what happened...

Toward the end of the meeting, the question of terminology was brought up explicitly, probably by Todd or Eric. Maddog mentioned "freely distributable" as an earlier term, and "cooperatively developed" as a newer term. Eric listed "free software," "open source," and "sourceware" as the main options. Todd advocated the "open source" model, and Eric endorsed this... Eric Raymond was far better positioned to spread the new meme, and he did. Bruce Perens signed on to the effort immediately, helping set up Opensource.org and playing a key role in spreading the new term... By late February, both O'Reilly & Associates and Netscape had started to use the term. After this, there was a period during which the term was promoted by Eric Raymond to the media, by Tim O'Reilly to business, and by both to the programming community. It seemed to spread very quickly.
Peterson remembers that "These months were extremely exciting for open source," adding "Every week, it seemed, a new company announced plans to participate. Reading Slashdot became a necessity, even for those like me who were only peripherally involved. I strongly believe that the new term was helpful in enabling this rapid spread into business, which then enabled wider use by the public."

Wikipedia notes that Linus Torvalds endorsed the term the day after it was announced, that Phil Hughes backed it in Linux Journal, and that Richard Stallman "initially seemed to adopt the term, but later changed his mind."

MojoKid writes: More drama is unfolding in the ultra-competitive retro arcade gaming scene... Billy Mitchell, the arcade legend who appeared as a central character opposite Steve Wiebe in the documentary The King of Kong: A Fistful of Quarters, has been accused of cheating his way into the record books for high scores in Donkey Kong. As a result, he's now been stripped of his 1.062 million score on the Donkey Kong Forums...

The legitimacy of his score was called into question by Donkey Kong high score judge Jeremy "Xelnia" Young laid out a body of evidence that seems to prove Mitchell recorded several of his high scores on the open source arcade emulator MAME, though he claimed his scores were obtained on an original arcade cabinet, and therefore were not subject to same strict authentication requirements. "It's possible they were recorded in one shot," Young says, but "Given the play style in Billy's videos, it's more likely that vanilla MAME's INP recording feature was abused."
Twin Galaxies recently threw out the 35-year-old record for the Atari 2600 game Dragster, and has now said they're "in the process of fully reviewing the compelling evidence provided by Jeremy Young."

An anonymous reader quotes the Seattle Post-Intelligencer: A private investigative team announced Thursday morning that members now believe D.B. Cooper was a black ops CIA operative possibly even involved with Iran-Contra, and that his identity has been actively hidden by government agents. The 40-member cold-case team comprised of several former FBI agents and led by Thomas and Dawna Colbert made its latest reveal after a code breaker working with the team found connections in each of five letters allegedly sent by Cooper in the days following the famed hijacking in 1971.

What's more, several people who knew Colbert's top suspect, a man named Robert W. Rackstraw, have noted possible connections to the CIA and to top-secret operations, Colbert said. "The new decryptions include a dare to agents, directives to apparent partners, and a startling claim that is followed by Rackstraw's own initials: If captured, he expects a get-out-of-jail card from a federal spy agency," Colbert said in a news release... In a brief phone call last year, Rackstraw only told SeattlePI to verify Colbert's claims; he didn't issue a denial, or comment further on Colbert's investigation...

Late last year, Colbert's team obtained a fifth letter allegedly sent by Cooper that Colbert said supports a possible FBI cover-up, but also included random letters and numbers. A code breaker on Colbert's team was able to decode the letters and numbers and find they pointed to three Army units Rackstraw was connected to during his military service in Vietnam. The code was meant to serve as a signal to his co-conspirators that he was alive and well after the jump, Colbert said... Another letter, in which Cooper claimed to be CIA openly, also had the letters "RWR" at the end -- the initials of Robert W. Rackstraw, according to Colbert.

A federal appeals court in San Francisco ruled yesterday that Twitter is not legally responsible for the deaths of two Americans in an ISIS-linked attack in Jordan, even though the Islamic State may have used its access to Twitter to spread its message of terrorism and recruit new members. The decision upholds a 2016 ruling on the same case, which was filed by the families of the victims of the terrorist attack. SFGate reports: "Without Twitter, the explosive growth of ISIS over the last few years into the most-feared terrorist group in the world would not have been possible," the suit said. The Americans, Lloyd Fields Jr. and James Creach, were former police officers working for U.S. companies training law enforcement officers in Jordan. They were among five people shot to death in November 2015 by a Jordanian police captain, later identified as a member of an Islamic State terror cell. Islamic State said it was responsible for killing the "American crusaders."

As an example of the Twitter activity, the women's lawyers showed a snapshot of an undated tweet, allegedly from Islamic State, that declared "there is no life without jihad." As of December 2014, the suit said, the terror group had 70,000 Twitter accounts, of which 79 were "official" Islamic State accounts. Only recently, the lawyers said, had Twitter changed its rules to prohibit threats of violence or terrorism and ordered the suspension of accounts promoting terrorism. But the Ninth U.S. Circuit Court of Appeals in San Francisco said the suit failed to show a direct connection between Islamic State's use of Twitter and the fatal attack. "At most, the (suit) establishes that Twitter's alleged provision of material support to ISIS facilitated the organization's growth and ability to plan and execute terrorist acts," Judge Milan Smith said in the 3-0 ruling, which upheld a federal judge's dismissal of the suit earlier.

schwit1 shares a report from ScienceAlert: People with high blood sugar stand to experience worse long-term cognitive decline than their healthy peers, even if they're not technically type 2 diabetic, new research suggests. The findings are not the first linking diabetes with impaired cognitive functions, but they're some of the clearest yet showing blood sugar isn't just a marker of our dietary health -- it's also a telling predictor of how our brains may cope as we get older. "Our findings suggest that interventions that delay diabetes onset, as well as management strategies for blood sugar control, might help alleviate the progression of subsequent cognitive decline over the long-term," explain the researchers, led by epidemiologist Wuxiang Xie from Imperial College London. The researchers sourced their data from the English Longitudinal Study of Aging, an ongoing assessment of the health of a representative sample of the English population aged 50 and older, which began in in 2002. For its analysis, the team tracked 5,189 participants -- 55 percent women, with an average age of 66 years -- assessing their level of cognitive function between 2004-2005 to 2014-2015, spanning several waves of the ELSA study. The findings are reported in the journal Diabetologia.

An anonymous reader writes: Linus Torvalds has released Linux 4.15 following the lengthy development cycle due to the Spectre v2 and Meltdown CPU vulnerability mitigation work. This update comes with many kernel improvements including RISC-V architecture support, AMDGPU Display Code support, Intel Coffee Lake graphics support, and many other improvements.
"This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle," Linus writes. "The extra two weeks were obviously mainly due to that whole timing issue... [T]he news cycle notwithstanding, the bulk of the 4.15 work is all the regular plodding 'boring' stuff. And I mean that in the best possible way. It may not be glamorous and get the headlines, but it's the bread and butter of kernel development, and is in many ways the really important stuff.

"Go forth and play with it, things actually look pretty good despite everything. And obviously this also means that the merge window for 4.16 is open... Hopefully we'll have a _normal_ and entirely boring release cycle for 4.16. Because boring really is good."
