How Genealogy Websites Make It Easier To Catch Killers (ieee.org) 73

An anonymous reader quotes a report from IEEE Spectrum: Over the past six months a small, publicly available genealogy database has become the go-to source for solving cold case crimes. The free online tool, called GEDmatch, is an ancestry service that allows people to submit their DNA data and search for relatives -- an open access version of AncestryDNA or 23andMe. Since April, investigators have used GEDmatch to identify victims, killers, and missing persons all over the U.S. in at least 19 cases, many of them decades old, according to authors of a report published today in Science. The authors predict that in the near future, as genetic genealogy reports gain in popularity, such tools could be used to find nearly any individual in the U.S. of European descent.

GEDmatch holds the genetic data of only about a million people. But cold case investigators have been exploiting the database using a genomic analysis technique called long-range familial search. The technique allows researchers to match an individual's DNA to distant relatives, such as third cousins. Chances are, one of those relatives will have used a genetic genealogy service. More than 17 million people have participated in these services -- a number that has grown rapidly over the last two years. AncestryDNA and 23andMe hold most of those customers. A genetic match to a distant relative can fairly quickly lead investigators to the person of interest. In a highly publicized case, GEDmatch was used earlier this year to identify the "Golden State Killer," a serial rapist and murderer who terrorized California in the 1970s and 1980s, but was never caught.
In April, investigators were able to use a genealogy database to narrow down DNA data from crime scenes and identify the "Golden State Killer," a serial rapist and murderer who terrorized California in the 1970s and 1980s.

Energy Department Proposes Funding For Ohio's First Offshore Wind Project 137

An anonymous reader quotes a report from Ars Technica: An energy development group has been working for years to put together Ohio's first offshore wind project. That might sound odd for a state so far from the sea, but the benefits of offshore wind (strong, consistent gusts and relative proximity to major population centers) translate to wind turbines that are placed in freshwater, too. Consequently, an area eight miles off Ohio's Lake Erie coastline is slated to see six new 3.45 megawatt (MW) turbines as part of a 20.7MW pilot installation. On Thursday, the Department of Energy (DOE) issued an Environmental Assessment stating that proceeding with the plan would not cause any "impact to the human environment." In an additional finding published by the DOE this week, the department added that it did not believe that the offshore wind project would cause significant damage to migratory birds, either. Finally, the DOE proposed an unspecified amount of funding for the project, which will be the first freshwater offshore wind project in the US and one of the first offshore wind projects overall. The Lake Erie Energy Department Corporation (LEEDCo) and Norwegian investor Fred Olsen Renewables (FOR) will be developing the "Icebreaker" project, as the turbine installation has been called. "Interestingly, the turbines will be secured to the lake using a 'Mono Bucket' foundation, with a suction-based design that's similar to what's been used on offshore oil-drilling platforms in the North Sea," reports Ars. "The design, LEEDCo says, uses 'the best and lowest-cost technology for sites 25 meters and less.'"

Two Events Celebrate Text Adventures, Roguelike Games (ifcomp.org) 19

An anonymous reader writes: The 24th annual Interactive Fiction Competition kicked off Monday, unveiling 77 new text adventures which will vie for nearly $9,000 in prize money. The contest's organizers are encouraging people to play and rate the free games, and encourage their friends to join in the fun (or to donate more prize money or other prizes). They're dedicating this year's competition to the memory of Stu Galley, who co-founded the pioneering text adventure company Infocom back in 1979 with his classmates from MIT. Infocom went on to create everything from Zork to a popular Hitchhiker's Guide to the Galaxy game, and Stu is credited as the driving force behind text adventures like Moonmist, Seastalker, and The Witness.
Meanwhile, long-time Slashdot reader paulproteus reminds us that the "Roguelike Celebration" is happening today and tomorrow at the GitHub office in San Francisco -- and is streaming on Twitch. The Roguelike Celebration is a community-generated weekend of talks, games, and conversations about roguelike [games] and related topics, including procedural generation and game design... It's for fans, players, developers, scholars, and everyone else, including people new to this type of game.

A Look at Facebook's Use of Systemd (phoronix.com) 84

At an event this month (you can find the video of it here), Davide Cavalca, a production engineer at Facebook, spoke about the growing adoption of systemd at the data centers of the company. From a report: Facebook continues making use of systemd's many features inside their data centers. Some of their highlights for systemd use in 2018 includes: Facebook's servers have been relying on systemd for about the past two years. Facebook is using CentOS 7 everywhere from hosts to containers. While relying on CentOS 7, Facebook backports a lot of packages including new systemd releases, Meson, other dependencies, and of course new Linux kernel releases. Facebook is working on "pystemd" as a Python (Cython) wrapper on top of SD-BUS.

A Shadowy Op-Ed Campaign Is Now Smearing SpaceX In Space Cities (arstechnica.com) 264

Last month when Boeing and SpaceX announced the first astronauts who will fly on their commercial crew spacecraft, several newspapers across the U.S. began publishing an op-ed that criticized the process by which Boeing competitor SpaceX fuels its Falcon 9 rocket. "The first op-ed appeared in a Memphis newspaper a week before the commercial crew announcement," reports Ars Technica. "In recent weeks, copies of the op-ed have also appeared in the Houston Chronicle, various Alabama newspapers, Albuquerque Journal, Florida Today, and The Washington Times." Ars Technica reports: All of these op-eds were bylined by "retired spacecraft operator" Richard Hagar, who worked for NASA during the Apollo program and now lives in Tennessee. (Based upon his limited social media postings, Hagar appears to be more interested in conservative politics than in space these days). Each op-ed cites Hagar's work on NASA's recovery from the Apollo 1 fire and the hard lessons NASA learned that day about human spaceflight. The pieces then pivot to arguing that SpaceX's load-and-go fueling process -- in which the crew will board the Dragon spacecraft on top of the Falcon 9 rocket before it is fueled -- ignores the lessons that Hagar's generation learned during Apollo.

"It's concerning to learn that some of the newer private space ventures launching today don't appreciate the same safety standards we learned to emphasize on Apollo," the op-ed states. "I suppose for Mr. Musk, inexperience is replacing the abundant safety protocols drilled into us after witnessing the Apollo 1 disaster. Astronaut safety is NASA's number one priority on any space mission. There is no reason it should not be for private space travel, but commercial space companies like SpaceX play by different rules."

There are some factual inaccuracies here. For one thing, SpaceX does play by the same rules as Boeing for commercial crew -- astronaut safety rules that NASA itself wrote. Moreover, NASA has already provisionally cleared load-and-go for Falcon 9 launches that will send the Dragon spacecraft into orbit. To try to understand his viewpoint, Ars attempted to reach Hagar by phone and email in September. In the course of this process, we learned that he did not actually submit many of these op-eds. In fact, based upon our research, at least four of the six op-eds that we located were submitted by two people with gmail.com addresses. Their names were Josh Brevik and Casey Murray. Further research revealed that two people with these names worked as "associates" at a Washington, DC-based public relations firm named Law Media Group or LMG.
LMG's website says they are a 15-year-old firm that "develops and executes public-, Hill-, and agency-facing issue advocacy campaigns that shift the narrative in a changing world." The SourceWatch website more bluntly "calls LMG a 'secretive Washington DC public affairs firm' with a history of placing op-eds, and it seeks to mask the op-eds' financial sponsors," reports Ars.

Linux Kernel Finally Nearing Support For The Apple Magic Trackpad 2, Thanks To a Google Employee (phoronix.com) 52

Michael Larabel, writing for Phoronix: Apple announced the Magic Trackpad 2 almost three years ago to the day while the mainline Linux kernel will finally be supporting this multi-touch device soon. The Magic Trackpad 2 is a wired/wireless touchpad with haptic feedback support and is a much larger touchpad compared to the original Magic Trackpad. There unfortunately hasn't been any mainline Linux kernel support for the Magic Trackpad 2, but some out-of-tree options. [...] However, as seen by this bug report there have been plenty of people since 2015 interested in using the Magic Trackpad 2 on Linux. Fortunately, Sean O'Brien of Google's Chrome OS team has been working on Magic Trackpad 2 support with a focus on getting it mainlined. The patch, which was also reviewed by other Google/ChromeOS developers, is now up to its third and perhaps final revision.

New Web Site Will Team Journalists With Programmers (sfgate.com) 51

schwit1 shared an article from the New York Times: When investigative journalist Julia Angwin worked for ProPublica, the nonprofit news organization became known as "Big Tech's scariest watchdog." By partnering with programmers and data scientists, Angwin pioneered the work of studying Big Tech's algorithms -- the secret codes that have an enormous effect on everyday American life... Now, with a $20 million gift from Craigslist founder Craig Newmark, she and her partner at ProPublica, data journalist Jeff Larson, are starting the Markup, a news site dedicated to investigating technology and its effect on society. Sue Gardner, former head of the Wikimedia Foundation, which hosts Wikipedia, will be the Markup's executive director. Angwin and Larson said that they would hire two dozen journalists for its New York office and that stories would start going up on the website in early 2019...

Angwin, who was part of a Wall Street Journal team that won a Pulitzer Prize in 2003 for coverage of corporate corruption, said the newsroom would be guided by the scientific method, and each story would begin with a hypothesis... At the Markup, journalists will be partnered with a programmer from a story's inception until its completion. "To investigate technology, you need to understand technology," said Angwin, 47... Newmark, who splits his time between San Francisco and New York, has for years kept a low profile. But he worries about what he sees as a lack of self-reflection among engineers. "Sometimes it takes an engineer a while to understand that we need help, then we get that help, and then we do a lot better," Newmark said. "We need the help that only investigative reporting with good data science can provide...."

Engineers being surprised by the tools they have made is, to the Markup team, part of the problem. "Part of the premise of the Markup is the level of understanding technology and its effects is very, very low, and we would all benefit from a broader understanding," Gardner said. "And I would include people who work for the companies."

Larson laments a world where programs handle crucial decisions, and "once they go into production, there's no oversight..." Or, as he says earlier, "Increasingly, algorithms are used as shorthand for passing the buck." The Markup's site promises " a nonpartisan, nonprofit newsroom" offering independent analysis of how technology is re-shaping everything from what we believe to "who goes to prison versus who remains free." The site's donations page adds that "We strive for fairness and independence and for us, the best way to achieve that is to operate without ads or a paywall."

Angwin tells Recode that she grew up in Steve Jobs' neighborhood in Palo Alto, and in a long interview reveals that she learned to program in a fifth grade class that a public-spirited Steve Jobs funded. Now the Times points out that the Markup "will release all its stories under a creative commons license so other organizations can republish them, as ProPublica does."

Humans Are Causing the Earth To Wobble More Than It Should, NASA Finds (bgr.com) 205

A reader shares a report from BGR: When looking at the Earth from afar it appears to be a perfect sphere, but that actually isn't the case. Because Earth isn't uniform on all sides due to land masses that shift and change over time, our planet actually wobbles a bit when it spins. Now, a new study by researchers with NASA's Jet Propulsion Laboratory and several universities and science centers has pinpointed the causes of Earth's imperfect spin, called "polar motion," and they found that humans are contributing to it. The researchers used a wealth of data gathered over 100 years to build mathematical models to trace the causes of the wobble and found that three factors are at play, and mankind is responsible for one of them. Two of the three factors identified by the scientists are glacial rebound and mantle convection. Glacial rebound happens when thick ice sheets physically push down on land masses, compressing them, but then release that pressure upon melting. The land then balloons back up over time, causing Earth's spin to wobble as if slightly off-axis. The effects of the last ice age, which would have compressed a huge amount of land across many continents, is still being felt today in the form of glacial rebound.

Mantle convection, the other uncontrollable factor in Earth's wobble, relates to our planet's inner workings. The plates on Earth's surface are in constant flux due to the movement of liquid rock far beneath our feet. The researchers believe these currents also contribute to the planet's imperfect spin. The third and final factor identified by the scientists is the massive loss of ice on Greenland and other areas, which is the direct result of global warming thanks to human activities. The researchers estimate that Greenland has lost roughly 7,500 gigatons, or 7,500,000,000,000 metric tons of ice due to global warming. All that ice loss has happened in the 20th century, and greenhouse gas production has been cited as the primary culprit. Losing all that mass has caused a significant shift on the planet and has contributed to the wobble as well.

Over 1,100 New Arcade Games Added To the Internet Archive (archive.org) 46

Jason Scott, writing for Internet Archive blog: The Internet Arcade, our collection of working arcade machines that run in the browser, has gotten a new upgrade in its 4th year. Advancements by both the MAME emulator team and the Emscripten conversion process allowed our team to go through many more potential arcade machines and add them to the site. The majority of these newly-available games date to the 1990s and early 2000s, as arcade machines both became significantly more complicated and graphically rich, while also suffering from the ever-present and home-based video game consoles that would come to dominate gaming to the present day. Even fervent gamers might have missed some of these arcade machines when they were in the physical world, due to lower distribution numbers and shorter times on the floor.

Southern California Sees Its Longest Streak of Bad Air In Decades (sfchronicle.com) 107

According to state monitoring data, Southern California violated federal smog standards for 87 consecutive days -- the longest stretch of bad air in at least 20 years. "The streak is the latest sign that Souther California's battle against smog is faltering after decades of dramatic improvement," reports San Francisco Chronicle. From the report: The ozone pollution spell began June 19 and continued through July and August, with every day exceeding the federal health standard of 70 parts per billion somewhere across Los Angeles, Orange, Riverside and San Bernardino counties. It didn't relent until Sept. 14, when air pollution dipped to "moderate" levels within federal limits for ozone, the lung-damaging gas in smog that triggers asthma and other respiratory illnesses. It's not unusual for Southern California summers to go weeks without a break in the smog, especially in inland communities that have long suffered the nation's worst ozone levels. But environmentalists and health experts say the persistence of dirty air this year is a troubling sign that demands action. Regulators blame the dip in air quality in recent years on hotter weather and stronger, more persistent inversion layers that trap smog near the ground.

The Linux Kernel Has Grown By 225,000 Lines of Code This Year, With Contributions From About 3,300 Developers (phoronix.com) 88

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.

What Cardiologists Think About the Apple Watch's Heart-Tracking Feature (sfgate.com) 90

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.

Some Linux Gamers Using Wine/DXVK To Play Blizzard's Overwatch Banned (phoronix.com) 81

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."

Apple Moves the iPhone Away From Physical SIMs (arstechnica.com) 204

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.

Nintendo Shuts Down Tool Used To Build Pokemon Fan Games (arstechnica.com) 78

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."
