LLVM release manager Hans Wennborg announced Wednesday the official availability of LLVM 7.0 compiler stack as well as associated sub-projects including the Clang 7.0 C/C++ compiler front-end, Compiler-RT, libc++, libunwind, LLDB, and others. From a report: There is a lot of LLVM improvements ranging from CPU improvements for many different architectures, Vega 20 support among many other AMDGPU back-end improvements, the new machine code analyzer utility, and more. The notable Clang C/C++ compiler has picked up support for function multi-versioning (FMV), initial OpenCL C++ support, and many other additions. See my LLVM 7.0 / Clang 7.0 feature overview for more details on the changes with this six-month open-source compiler stack update. Wennborg's release statement can be read on the llvm-announce list.

Here's an analysis of the Linux kernel repository that attempts to find some fresh numbers on the current kernel development trends. He writes: The kernel repository is at 782,487 commits in total from around 19.009 different authors. The repository is made up of 61,725 files and from there around 25,584,633 lines -- keep in mind there is also documentation, Kconfig build files, various helpers/utilities, etc. So far this year there has been 49,647 commits that added 2,229,836 lines of code while dropping 2,004,759 lines of code. Or a net gain of just 225,077 lines. Keep in mind there was the removal of some old CPU architectures and other code removed in kernels this year so while a lot of new functionality was added, thanks to some cleaning, the kernel didn't bloat up as much as one might have otherwise expected. In 2017 there were 80,603 commits with 3,911,061 additions and 1,385,507 deletions. Given just over one quarter to go, on a commit and line count 2018 might come in lower than the two previous years.

Linus Torvalds remains the most frequent committer at just over 3% while the other top contributions to the kernel this year are the usual suspects: David S. Miller, Arnd Bergmann, Colin Ian King, Chris Wilson, and Christoph Hellwig. So far in 2018 there were commits from 3,320 different email addresses. This is actually significantly lower than in previous years.

An anonymous reader quotes a report from SFGate: The newest Apple Watch can now flag potential problems with your heartbeat -- a feature that's been cleared by the Food and Drug Administration and that Apple is marking as a major achievement. But some doctors said that including heart-monitoring tools in such a popular consumer product could prompt unnecessary anxiety and medical visits. Physicians say the watch could be good for patients who have irregular heart rhythms but may not realize it. Some people who have atrial fibrillation, the condition for which the watch is screening, don't always have noticeable symptoms. In an ideal situation, someone who doesn't know they have a problem could get a warning from their watch and take that data to their doctor.

But there is also concern that widespread use of electrocardiograms without an equally broad education initiative could burden an already taxed health-care system. Heart rhythms naturally vary, meaning that it's likely that Apple Watch or any heart monitor could signal a problem when there isn't one -- and send someone running to the doctor for no reason. "People are scared; their heart scares them," John Mandrola, a cardiologist at Baptist Health in Louisville, said. "That leads to more interaction with the health-care system." An extra visit to your doctor may not sound like a bad thing, but Mandrola said it would potentially lead to another round of tests or even unnecessary treatment if there are other signs that can be misinterpreted. And doctors might wind up facing a crowd of anxious Apple Watch users getting false signals -- something physicians have already had to deal with as fitness trackers that monitor heart rates have become popular.

Longtime Slashdot reader DrYak writes: Phoronix is reporting that multiple users who all use Wine and DXVK compatibility layers have seen their Overwatch accounts banned by Blizzard. Previously, Blizzard has stated: "playing on Linux or even a Mac while on an emulated Windows environment is not bannable." But users report on Reddit getting banned simply after testing some rendering options. Tech support has answered that they are escalating the ticket and trying to take a closer look, hoping to avoid this from happening to other Linux users. According to Phoronix, the most common explanation for the bans "is a false-positive from Blizzard's anti-cheat technology having issue with DXVK."

The new iPhone XS and iPhone XS Max will use eSIM technology to allow users to use two phone lines on a single device. You could have a work or personal number, or an American and Canadian number if you travel across the border frequently. The reprogrammable SIM card is "soldered onto the iPhone's motherboard directly," and measures just 6 millimeters by 5 millimeters," reports Ars Technica, citing GSMArena.com. From the report: These handsets will have a new "dual SIM dual standby" option, one of which will be a nano SIM. In other words, they will have two distinct phone numbers. (Chinese models will have two SIM slots instead of the eSIM option.) Since their debut in 1991, traditional, physical SIM cards have decreased dramatically in size. eSIMs have already been around for nearly a year, since they were introduced into the Apple Watch and Google Pixel 2, among other devices.

The Microtransat has been running since 2010 and has seen 23 previous entries all fail to make it across. The successful boat, SB Met was built by the Norwegian company Offshore Sensing AS and is only 2 metres (6.5 ft) long. It completed the crossing on August 26th, 79 days and 5000 km (3100 miles) of sailing after departing Newfoundland on June 7th.

"Using the newly minted Linux 4.19 feature code, fresh benchmarks were carried out looking at the performance cost of Spectre/Meltdown/Foreshadow mitigations on Intel Xeon v. AMD EPYC CPUs," writes an anonymous Slashdot reader: Workloads affected by these CPU vulnerabilities mainly deal with I/O and frequent kernel calls while CPU bound tests are still found to be minimally impacted. When toggling these mitigations on Linux 4.19, Intel Xeon CPUs were found to be 10~15% slower with the default kernel while AMD EPYC CPUs dropped to about 5% slower.

An anonymous reader quotes a report from Ars Technica: Since 2007, Pokemon Essentials has been a crucial part of the Pokemon fan game community. As a free mod for the paid RPG Maker software, Pokemon Essentials offers all the graphics, music, maps, and tilesets a fan game maker needs to craft their own Poke-adventure. Fans of the tool congregated around the PokeCommunity forums and a dedicated Pokemon Essentials wiki to download files, share creations, and discuss the scene. Earlier this week, however, PokeCommunity forum moderator Marin announced that "the Pokemon Essentials wikia and all downloads for it have been taken down due to a copyright claim by Nintendo of America." That means "we will not allow Pokemon Essentials or any of its assets to be hosted or distributed on PokeCommunity," the announcement reads. "We sincerely apologize that we have to do this, but there is no going around it." Fandom, the company that hosts the wiki, confirmed to the Verge that it had "received a DMCA notice on behalf of Nintendo notifying us of content that was in violation of its copyright holdings. After carefully assessing the violations in regards to the Pokemon Essentials wiki, we came to a decision to take it down."

NASA and the University of Texas have teamed up to digitize 19,000 hours of recordings from the Apollo 11 mission that landed the first two people on the moon. From a report: The audio was uploaded to the Internet Archive, a nonprofit website that hosts digitized versions of cultural artifacts. "One of the things that comes across is that each of the people working for NASA is proud of what they do. They were always working collaboratively," John Hansen, a speech researcher at the university and principal investigator for the project, told NBC News.

An anonymous reader writes: Linus Torvalds released on Sunday Linux 4.19-rc1 that he describes as a "fairly frustrating merge window" following the new features landing over the past two weeks. What does this "pretty big release" offer? Phoronix's Linux 4.19 feature overview sheds light on more Spectre CPU mitigations for x86/POWER/s390, the new EROFS read-only Android file-system, a Raspberry Pi voltage driver, ThinkPad calculator key support, an in-kernel GPS subsystem, the Google GASKET driver framework, virtual kernel mode-setting, Qualcomm Adreno 600 series support, and many other improvements.

An anonymous reader writes: I know PHP isn't to some devs liking, but chances are you know people who work with PHP or have sites that are built with it. PHP 5.6 and 7.0 are shortly coming to the end of the support period for security patches, so what plans have you made to migrate code and sites to newer platforms? With apparently huge numbers (80%) of sites still running PHP 5.6, there appears to be little industry acknowledgement of the issue. Is there a ticking PHP Time Bomb waiting to go off?

Programmers may love hot newer languages like Kotlin and Rust, but according to a Cloud Foundry Foundation (CFF) recent survey of global enterprise developers and IT decision makers, Java and Javascript are the top enterprise languages. ZDNet: That said, the CFF also found [PDF] that, "More and more, businesses are employing a polyglot and a multi-platform strategy to meet their exact needs." The CFF discovered 77 percent of enterprises are using or evaluating Platforms-as-a-Service (PaaS); 72 percent are using or considering containers; and 46 percent are using or thinking about serverless computing. Simultaneously, more than a third (39 percent) are using all three technologies together. For companies this "flexibility of cloud-native practices enables [companies to move] away from a monolithic approach and towards a world of computing that is flexible, portable and interoperable." That means, while Java and JavaScript are only growing ever more popular, the larger the company, the more languages are used. After the Java twins, C++, C#, Python, and PHP are the most popular languages.

An anonymous reader shares a report from NPR about ecologist Chelsea Rochman, who has dedicated her career to studying how microplastics are getting into the food chain and affecting everything from beer to fish: Since modern plastic was first mass-produced, 8 billion tons have been manufactured. And when it's thrown away, it doesn't just disappear. Much of it crumbles into small pieces. Scientists call the tiny pieces "microplastics" and define them as objects smaller than 5 millimeters -- about the size of one of the letters on a computer keyboard. Researchers started to pay serious attention to microplastics in the environment about 15 years ago. They're in oceans, rivers and lakes. They're also in soil. Recent research in Germany found that fertilizer made from composted household waste contains microplastics. And, even more concerning, microplastics are in drinking water. In beer. In sea salt. In fish and shellfish. How microplastics get into animals is something of a mystery, and Chelsea Rochman is trying to solve it.

Since she started studying microplastics, Rochman has found them in the outflow from sewage treatment plants. And they've shown up in insects, worms, clams, fish and birds. To study how that happens, [researcher Kennedy Bucci] makes her own microplastics from the morning's collection. She takes a postage stamp-size piece of black plastic from the jar, and grinds it into particles using a coffee grinder. "So this is the plastic that I feed to the fish," she says. The plastic particles go into beakers of water containing fish larvae from fathead minnows, the test-animals of choice in marine toxicology. Tanks full of them line the walls of the lab. Bucci uses a pipette to draw out a bunch of larvae that have already been exposed to these ground-up plastic particles. The larva's gut is translucent. We can see right into it. "You can see kind of a line of black, weirdly shaped black things," she points out. "Those are the microplastics." The larva has ingested them. Rochman says microplastic particles can sicken or even kill larvae and fish in their experiments.

Saint Louis University announced this week a plan to outfit living spaces with 2,300 Echo Dots. The smart speakers will be ready by the time classes start later this month. TechCrunch reports: SLU is quick to note that it's "the first college or university in the country to bring Amazon Alexa-enabled devices, managed by Alexa for Business, into every student residence hall room and student apartment on campus." It's certainly not the first to adopt Amazon's smart speakers, but it's among the largest scale for this sort of deployment. While the product has become a mainstay in plenty of American homes, it does seem like an odd choice dorms and student campus. SLU has worked with Alexa for Business to create 100 custom questions, including, "What time does the library close tonight?" and "Where is the registrar's office?"

The company addressed [the privacy concerns] on a privacy page, writing: "Because of our use of the Amazon Alexa for Business (A4B) platform, your Echo Dot is managed by a central system dedicated to SLU. This system is not tied to individual accounts and does not maintain any personal information for any of our users, so all use currently is anonymous. Additionally, neither Alexa nor the Alexa for Business management system maintains recordings of any questions that are asked."

Long-time Slashdot reader tdailey spotted a new version of Pale Moon, a customised version of Firefox optimized for speed and efficiency. Beta News reports it's the first major update since November of 2016:

There are virtually no visual or obvious changes in this new major build, but the under-the-hood changes are both extensive and necessary.... Despite all the updates, Moonchild is keen to stress certain things haven't changed -- unlike Firefox, for example, Pale Moon continues to support NPAPI plugins, complete themes and a fully customizable user interface. There is also no DRM built into the browser, although third-party plugins such as Silverlight are supported. It will also continue to work with certain "legacy" plugins of the type abandoned by Firefox.
Pale Moon strips out what one reviewer calls "little-used components" of Firefox, including parental controls and accessbility features, as well as crash reports and support for Internet Explorer's ActiveX and ActiveX scripting technology.

"Proving that open source leads to great development, Pale Moon takes the already decent Firefox web browser and makes it even better and a faster."

Two months have passed since NASA's Opportunity Mars rover last phoned home. The last time we reported on the rover was on June 12th, when it was trying to survive an intensifying dust storm that was deemed "much worse than a 2007 storm that Opportunity weathered," according to NASA. "The previous storm had an opacity level, or tau, somewhere above 5.5; this new storm had an estimated tau of 10.8." Space.com reports on Opportunity's current status: Opportunity hasn't made a peep since June 10, when dust in the Red Planet's air got so thick that the solar-powered rover couldn't recharge its batteries. Opportunity's handlers think the six-wheeled robot has put itself into a sort of hibernation, and they still hope to get a ping once the dust storm has petered out. And there are good reasons for this optimism, NASA officials said. "Because the batteries were in relatively good health before the storm, there's not likely to be too much degradation," NASA officials wrote in an Opportunity update Thursday (Aug. 16). "And because dust storms tend to warm the environment -- and the 2018 storm happened as Opportunity's location on Mars entered summer -- the rover should have stayed warm enough to survive."

Engineers are trying to communicate with Opportunity several times a week using NASA's Deep Space Network, a system of big radio dishes around the globe. They hail the robot during scheduled "wake-up times" and then listen for a response. And team members are casting a wider net, too: Every day, they sift through all radio signals received from Mars, listening for any chirp from Opportunity, NASA officials said. Even if Opportunity does eventually wake up and re-establish contact, its long ordeal may end up taking a toll on the rover. "The rover's batteries could have discharged so much power -- and stayed inactive so long -- that their capacity is reduced," NASA officials wrote in the update. "If those batteries can't hold as much charge, it could affect the rover's continued operations. It could also mean that energy-draining behavior, like running its heaters during winter, could cause the batteries to brown out."

An anonymous reader quotes a report from The Intercept: The National Security Agency successfully broke the encryption on a number of "high potential" virtual private networks, including those of media organization Al Jazeera, the Iraqi military and internet service organizations, and a number of airline reservation systems, according to a March 2006 NSA document. The fact that the NSA spied on Al Jazeera's communications was reported by the German newsmagazine Der Spiegel in 2013, but that reporting did not mention that the spying was accomplished through the NSA's compromise of Al Jazeera's VPN. During the Bush administration, high-ranking U.S. officials criticized Al Jazeera, accusing the Qatar-based news organization of having an anti-American bias, including because it broadcasted taped messages from Osama bin Laden.

According to the document, contained in the cache of materials provided by NSA whistleblower Edward Snowden, the NSA also compromised VPNs used by airline reservation systems Iran Air, "Paraguayan SABRE," Russian airline Aeroflot, and "Russian Galileo." Sabre and Galileo are both privately operated, centralized computer systems that facilitate travel transactions like booking airline tickets. Collectively, they are used by hundreds of airlines around the world. In Iraq, the NSA compromised VPNs at the Ministries of Defense and the Interior; the Ministry of Defense had been established by the U.S. in 2004 after the prior iteration was dissolved. Exploitation against the ministries' VPNs appears to have occurred at roughly the same time as a broader "all-out campaign to penetrate Iraqi networks," described by an NSA staffer in 2005.

An anonymous reader quotes a report from Ars Technica: Hackers have uncovered and tested a screen-splitting "VR Mode" that has been buried in the Switch's system-level firmware for over a year. The discovery suggests that Nintendo at least toyed with the idea that the tablet system could serve as a stereoscopic display for a virtual reality headset. Switch hackers first discovered and documented references to a "VrMode" in the Switch OS' Applet Manager services back in December when analyzing the June 2017 release of version 3.0.0 of the system's firmware. But the community doesn't seem to have done much testing of the internal functions "IsVrModeEnabled" and "SetVrModeEnabled" at the time. That changed shortly after Switch modder OatmealDome publicly noted one of the VR functions earlier this month, rhetorically asking, "has anyone actually tried calling it?" Fellow hacker random0666 responded with a short Twitter video (and an even shorter followup) showing the results of an extremely simple homebrew testing app that activates the system's VrMode functions.

As you can see in those video links, using those functions to enable the Switch's VR mode splits the screen vertically into two identical half-sized images, in much the way other VR displays split an LCD screen to create a stereoscopic 3D effect. System-level UI elements appear on both sides of the screen when the mode is enabled, and the French text shown in the test can be roughly translated to "Please move the console away from your face and click the close button." The location of the functions in the Switch firmware suggest they're part of Nintendo's own Switch code and not generic functions included in other Nvidia Tegra-based hardware.

Apple argued that buildings it owned around Cupertino, where it is headquartered, were only worth $200 instead of the $1 billion tax assessors deemed in 2015, according to appeals reviewed by the San Francisco Chronicle. From a report: The report characterized the dispute as part of an aggressive strategy by Apple to lower its tax bills. According to the Chronicle, Apple has 489 open appeals in tax disputes over property assessed at $8.5 billion in Santa Clara County, Calif., dating back to 2004. Those appeals include the $1 billion building assessed by tax officials, as well as another $384 million property that Apple also claims is worth $200. Apple is now valued at $1 trillion. It is also the county's biggest taxpayer, paying $56 million in the 2017-2018 tax year.

New submitter SteveSgt writes: A forum thread on QRZ.com indicates that the shortwave time broadcasts by the National Institute of Standards and Technology (NIST) from stations WWV (Colorado) and WWVH (Hawaii) may be slashed in budget year 2019. [One of the proposed reductions includes "$6.3 million supporting fundamental measurement dissemination, including the shutdown of NIST radio stations in Colorado and Hawaii."] While the WWV broadcasts may seem like an anachronism to some Slashdotters, they remain a crucial component in many unexpected services, from over-the-air broadcasters and traffic signals, to medical devices, wall clocks, and wrist watches. The signals serve as standard beacons for radio propagation, and as a frequency reference for alignment of a broad range of communications equipment. It's easy to imagine that not even the NIST knows every service and device that could be impacted by this decision.
