Linux's longevity is a testament to the open source community as a whole, and not just one man, such as Linus Torvalds.

Continuing its rapid release cycle, ReactOS has unveiled version 0.4.2 of its free "open-source binary-compatible Windows re-implementation." Slashdot reader jeditobe reports that this new version can now read and write various Linux/Unix file systems like Btrfs and ext (and can read ReiserFS and UFS), and also runs applications like Thunderbird and 7-Zip.ReactOS 0.4.2 also features Cygwin support, .NET 2.0 and 4.0 application support, among other updated packages and revised external dependencies such as Wine and UniATA. The team also worked to improve overall user experience... ReactOS is free. You can boot your desktop or laptop from it. It looks like Windows (a 10-year-old version, anyway), so you already know how to use it. And it'll run some Windows and DOS applications, maybe including DOS games that regular 64-bit Windows can no longer touch.These videos even show ReactOS running Elder Scrolls: Skyrim and Doom 3.

[slashdot.org] Cybercriminals Select Insiders To Attack Telecom Providers
An anonymous reader quotes a report from Help Net Security:Cybercriminals are using insiders to gain access to telecommunications networks and subscriber data, according to Kaspersky Lab. In addition, these criminals are also recruiting disillusioned employees through underground channels and blackmailing staff using compromising information gathered from open sources... According to Kaspersky Lab researchers, if an attack on a cellular service provider is planned, criminals will seek out employees who can provide fast track access to subscriber and company data or SIM card duplication/illegal reissuing. If the target is an Internet service provider, the attackers will try to identify the employees who can enable network mapping and man-in-the-middle attacks.

[slashdot.org] HAARP Holds Open House To Dispel Rumors Of Mind Control
An anonymous Slashdot reader writes:HAARP -- the former Air Force/Navy/DARPA research program in Alaska -- will host an open house Saturday where "We hope to show people that it is not capable of mind control and not capable of weather control and all the other things it's been accused of..." said Sue Mitchell, spokesperson for the geophysical institute at the University of Alaska. "We hope that people will be able to see the actual science of it." HAARP, which was turned over to The University of Alaska last August, has been blamed for poor crop yields in Russia, with conspiracy theorists also warning of "a super weapon capable of mind control or weather control, with enough juice to trigger hurricanes, tornadoes and earthquakes." The facility's 180 high-frequency antennas -- spread across 33 acres -- will be made available for public tours, and there will also be interactive displays and an unmanned aircraft 'petting zoo'. The Alaska Dispatch News describes it as "one of the world's few centers for high-power and high-frequency study of the ionosphere... important because radio waves used for communication and navigation reflect back to Earth, allowing long-distance, short-wave broadcasting."

[slashdot.org] Eavesdropping On Tinder: Researcher Demonstrates Man-in-the-Middle Attacks
An anonymous Slashdot reader writes:Security expert Anthony Zboralski posted on HERT a social engineering attack for Tinder that lets you perform a man-in-the-middle attack against unsuspecting users. Zboralski says, "Not only we can eavesdrop on the conversation of two strangers, we can also change their reality." The attack can easily be extended to SMS, Whatsapp, iMessage and voice. "At some point people exchange phone numbers and the Tinder convo stops. That's not a problem..." Zboralski explains, suggesting more ways to continue the man-in-the-middle exploits.. His article drew a response from Tinder, arguing they "employ several manual and automated mechanisms" to deter fake and duplicate profiles. But while they're looking for ways to improve, "ultimately, it is unrealistic for any company to positively validate the real-world identity of millions of users while maintaining the commonly expected level of usability."

[slashdot.org] White House Is Planning To Let More Foreign Entrepreneurs Work In the US
Peter Hudson writes from a report via Recode: "After failing to get Congress to pass a 'startup visa' as part of broad immigration reform, the Obama administration is moving ahead with an alternative that would allow overseas entrepreneurs to live in the U.S. for up to five years to help build a company," reports Recode. "Already speaking out in favor of the new rules is PayPal co-founder Max Levchin: 'I believe that the most promising entrepreneurs from around the world should have the same opportunity I had -- the chance to deliver on their potential, here in America.' Levchin moved to the U.S. from the Soviet Union in 1991." There are three conditions that need to be met in order to be eligible to work in the U.S. under the new rule: the foreigner would have to own at least 15 percent of a U.S.-based startup, the foreigner would need to have a central role in the startup's operations, and the startup would need to have "potential for rapid business growth and job creation." The third requirement could be met by having at least $100,000 in government grants or $345,000 invested from U.S. venture investors. "Under [the International Entrepreneur Rule (PDF)] being formally proposed on Friday, the Department of Homeland Security would be empowered to use its existing authority to allow entrepreneurs to legally work in the country for two years, possibly followed by a one-time three-year extension," reports Recode. "While the public will have 45 days to comment, the rules aren't subject to congressional approval."

[slashdot.org] Floating Solar Device Boils Water Without Mirrors
An anonymous reader quotes a report from Ars Technica: Researchers from MIT and the Masdar Institute of Science and Technology, led by George Ni, describe a prototype design that boils water under ambient sunlight. Central to their floating solar device is a "selective absorber" -- a material that both absorbs the solar portion of the electromagnetic spectrum well and emits little back as infrared heat energy. For this, the researchers turn to a blue-black commercial coating commonly used in solar photovoltaic panels. The rest of the puzzle involves further minimizing heat loss from that absorber, either through convection of the air above it or conduction of heat into the water below the floating prototype. The construction of the device is surprisingly simple. At the bottom, there is a thick, 10-centimeter-diameter puck of polystyrene foam. That insulates the heating action from the water and makes the whole thing float. A cotton wick occupies a hole drilled through the foam, which is splayed and pinned down by a square of thin fabric on the top side. This ensures that the collected solar heat is being focused into a minute volume of water. The selective absorber coats a disc of copper that sits on top of the fabric. Slots cut in the copper allow water vapor from the wick to pass through. And the crowning piece of this technological achievement? Bubble wrap. It insulates the top side of the absorber, with slots cut through the plastic to let the water vapor out. Tests in the lab and on the MIT roof showed that, under ambient sunlight, the absorber warmed up to 100 degrees Celsius in about five minutes and started making steam. That's a first. The study has been published in two separate Nature articles: "Steam by thermal concentration" and "Steam generation under one sun enabled by a floating structure with thermal concentration."

[slashdot.org] Juno Probe To Get First Up-Close Look At Jupiter On Saturday
NASA's Juno spacecraft will get its first up-close view at Jupiter this Saturday. Space.com reports: "At 8:51 a.m. EDT (1251 GMT) on Saturday (Aug. 27), Juno will zoom within 2,600 miles (4,000 kilometers) of Jupiter's cloud tops -- closer than the probe is scheduled to come during its entire mission, NASA officials said. And Juno will have all of its science instruments during Saturday's flyby. This was not the case during the spacecraft's only previous close approach to Jupiter, which occurred July 4 when Juno arrived in orbit around the giant planet. During Saturday's close pass, all eight of Juno's science instruments will be collecting data, and the probe's visible-light imager, known as JunoCam, will take close-up photos." You can also look forward to Venus-Jupiter Conjunction 2016, an event happening on August 27 where Venus and Jupiter's respective orbits will bring the two planets the closest that they'll be to each other until 2065. The two planets will be positioned roughly five degrees above the Western horizon on August 27.

[lwn.net] [$] Trying out openSUSE Tumbleweed
While distribution-hopping is common among newcomers to Linux, longtimeusers tend to settle into a distribution they like and stay putthereafter. In the end, Linux distributions are more alike than different,and one's time is better spent getting real work done rather than lookingfor a shinier version of the operating system. Your editor, however,somehow never got that memo; that's what comes from ignoring Twitter,perhaps. So there is a new distribution on the main desktop machine; thistime around it's openSUSE Tumbleweed.

In honor of Women's Equality Day, an anonymous reader shares with us a festive report from Fortune: More than two months after the White House first announced its Equal Pay Pledge for the private sector, Facebook, Apple, Microsoft and other major industry players have signed on. By taking the pledge, which was first introduced at the United State of Women Summit in June of this year, companies promise to help close the national gender pay gap, conduct annual, company-wide pay analyses, and review hiring and promotion practices. The new signees were announced in a White House statement on Friday -- which also happens to be Women's Equality Day, the anniversary of the ratification of the 19th amendment, which gave women the right to vote. Apple, which announced earlier this year that it has no pay gap, released a statement promising to dig even deeper into compensation. "We're now analyzing the salaries, bonuses, and annual stock grants of all our employees worldwide. If a gap exists, we'll address it," the company said in a statement. Twenty-nine companies signed the pledge on Friday, bringing the total number of signatories to 57. The pledge is part of a $50-million, White House-led initiative to expand opportunities for and improve the lives of women and girls. The consortium members issued a statement via Whitehouse.gov's press release: "The Employers for Pay Equity consortium is comprised of companies that understand the importance of diversity and inclusion, including ensuring that all individuals are compensated equitably for equal work and experience and have an equal opportunity to contribute and advance in the workplace. We are committed to collaborating to eliminate the national pay and leadership gaps for women and ethic minorities. Toward that end, we have come together to share best practices in compensation, hiring, promotion, and career development as well as develop strategies to support other companies' efforts in this regard. By doing so, we believe we can have a positive effect on our workforces that, in turn, makes our companies stronger and delivers positive economic impact." The consortium members include: Accenture, Airbnb, BCG, Care.com, CEB, Cisco, Deloitte, Dow, Expedia, EY, Glassdoor, GoDaddy, Jet.com, L'Oreal USA, Mercer, PepsiCo, Pinterest, Rebecca Minkoff, Salesforce, Spotify, Staples, Stella McCartney, and Visa.
