Mixed Reactions to GitHub's AI-Powered Pair Programmer 'Copilot' (github.blog) 39

Reactions are starting to come in for GitHub's new Copilot coding tool, which one site calls "a product of the partnership between Microsoft and AI research and deployment company OpenAI — which Microsoft invested $1 billion into two years ago." According to the tech preview page: GitHub Copilot is currently only available as a Visual Studio Code extension. It works wherever Visual Studio Code works — on your machine or in the cloud on GitHub Codespaces. And it's fast enough to use as you type. "Copilot looks like a potentially fantastic learning tool — for developers of all abilities," said James Governor, an analyst at RedMonk. "It can remove barriers to entry. It can help with learning new languages, and for folks working on polyglot codebases. It arguably continues GitHub's rich heritage as a world-class learning tool. It's early days but AI-assisted programming is going to be a thing, and where better to start experiencing it than GitHub...?"

The issue of scale is a concern for GitHub, according to the tech preview FAQ: "If the technical preview is successful, our plan is to build a commercial version of GitHub Copilot in the future. We want to use the preview to learn how people use GitHub Copilot and what it takes to operate it at scale." GitHub spent the last year working closely with OpenAI to build Copilot. GitHub developers, along with some users inside Microsoft, have been using it every day internally for months.

[Guillermo Rauch, CEO of developer software provider Vercel, who also is founder of Vercel and creator of Next.js], cited in a tweet a statement from the Copilot tech preview FAQ page, "GitHub Copilot is a code synthesizer, not a search engine: the vast majority of the code that it suggests is uniquely generated and has never been seen before."

To that, Rauch simply typed: "The future."

Rauch's post is relevant in that one of the knocks against Copilot is that some folks seem to be concerned that it will generate code that is identical to code that has been generated under open source licenses that don't allow derivative works, but which will then be used by a developer unknowingly...

GitHub CEO Nat Friedman has responded to those concerns, according to another article, arguing that training an AI system constitutes fair use: Friedman is not alone — a couple of actual lawyers and experts in intellectual property law took up the issue and, at least in their preliminary analysis, tended to agree with Friedman... [U.K. solicitor] Neil Brown examines the idea from an English law perspective and, while he's not so sure about the idea of "fair use" if the idea is taken outside of the U.S., he points simply to GitHub's terms of service as evidence enough that the company can likely do what it's doing. Brown points to passage D4, which grants GitHub "the right to store, archive, parse, and display Your Content, and make incidental copies, as necessary to provide the Service, including improving the Service over time." "The license is broadly worded, and I'm confident that there is scope for argument, but if it turns out that Github does not require a license for its activities then, in respect of the code hosted on Github, I suspect it could make a reasonable case that the mandatory license grant in its terms covers this as against the uploader," writes Brown. Overall, though, Brown says that he has "more questions than answers."
Armin Ronacher, the creator of the Flask web framework for Python, shared an interesting example on Twitter (which apparently came from the game Quake III Arena) in which Copilot apparently reproduces a chunk of code including not only its original comment ("what the fuck?") but also its original copyright notice.

The US Navy's Plans for a Railgun Are Finally Dead (popularmechanics.com) 109

Anyone who's played Quake remembers the railgun weapon. The U.S. Navy spent $500 million to try to build a real one, according to Popular Mechanics, "using electricity and magnetism instead of gunpowder and chemical energy to accelerate a projectile down a pair of rails." But now they've apparently given up: The service is ending funding for the railgun without having sent a single weapon to sea, while pushing technology derived from the program into existing weapons. The weapon is a victim of a change in the Navy's direction toward faster, longer-range weapons that are capable of striking ships and land targets in a major war. The Navy's budget request includes no funding for the railgun in 2022, The Drive reports...

Railguns are theoretically safer than conventional guns, since they reduce the amount of volatile powder a ship stores deep within its bowels in the ammunition magazine. The projectiles are also faster. But despite those advantages, there are reasons why the Navy is canning the railgun, which has been in development since 2005. For one, there are currently only three ships the Navy could conceivably fit the railgun to... The railgun concept itself is also out of step with the Navy's reorientation toward great power conflict, particularly a possible war with China or Russia. As an offensive weapon, the railgun's range of 50 to 100 miles is relatively short, placing a railgun-equipped ship within range of longer-range weapons, including China's DF-21D anti-ship ballistic missile.

And while the railgun also has defensive potential since it can shoot down incoming aircraft, missiles, and drones, the Navy already has plenty of existing missiles and guns to deal with those threats.

After Third Large Quake Near New Zealand, Tsunami Warning Issued; Tsunami Watch in Hawaii (washingtonpost.com) 32

A major magnitude 8.0 earthquake struck roughly 600 miles northeast of New Zealand on Thursday afternoon, triggering concerns of a potentially damaging tsunami. From a report: It's the third major earthquake in less than eight hours on the Kermadec Fault, which passes east of New Zealand. A magnitude 7.3 hit near New Zealand early on Thursday, followed by a 7.4 about 560 miles to the north a few hours later. Tsunami waves of 10 feet or greater are possible in the Kermadec Islands, with 3 to 9 foot waves in French Polynesia. American Samoa, the Cook Islands , Fiji, New Zealand and the Pitcairn Islands can expect water levels fluctuating by up to three feet. A tsunami warning was issued for American Samoa as well. A tsunami warning is in effect for New Zealand. The country's National Emergency Management Agency tweeted "TSUNAMI WARNING issued following Kermadecs earthquake." DW adds: The Pacific Tsunami Warning Center (PTWC) had withdrawn an earlier tsunami warning after the first quake, saying the threat had passed, but authorities renewed the warning following the second and third quake. There were no immediate reports of serious damage or casualties.

Simulating 800,000 Years of California Earthquake History To Pinpoint Risks (utexas.edu) 19

aarondubrow shares a report from the Texas Advanced Computing Center: A new study in the Bulletin of the Seismological Society of America presents results from a new earthquake simulator, RSQSim, that simulates hundreds of thousands of years of seismic history in California. Coupled with another code, CyberShake, the framework can calculate the amount of shaking that would occur for each quake. [The framework makes use of two of the most powerful supercomputers on the planet: Frontera, at the Texas Advanced Computing Center, and Summit, at Oak Ridge National Laboratory].

The new approach improves [seismologists'] ability to pinpoint how big an earthquake might occur at a given location, allowing building code developers, architects, and structural engineers to design more resilient buildings that can survive earthquakes at a specific site.

NVIDIA Apologizes, 'Walks Back' Threat to Withhold GPUs From Reviewer (techspot.com) 111

This week NVIDIA threatened to stop providing GeForce Founders Edition review units to reviewer Steven Walton, who runs the YouTube channel Hardware Unboxed (and is also an editor/reviewer at TechSpot). NVIDIA had complained "your GPU reviews and recommendations have continued to focus singularly on rasterization performance, and you have largely discounted all of the other technologies we offer gamers. It is very clear from your community commentary that you do not see things the same way that we, gamers, and the rest of the industry do."

NVIDIA's email to Walton had said that henceforward their review products would instead be allocated to other media outlets "that recognize the changing landscape of gaming and the features that are important to gamers and anyone buying a GPU today, be it for gaming, content creation, or studio and stream."

But TechSpot reports tonight that "Less than 48 hours later, Steve received the good news. Nvidia apologized and walked everything back." Great news indeed, but let's be clear this wouldn't have happened if not for the support of the community at large and key people in the tech space that have such an enormous influence that it was too much for Nvidia to ignore. Linus from LinusTechTips (his angry rant on the WAN Show embedded above is pure gold) and Steve from Gamers Nexus, were two of those persons.
And unfortunately, by then TechSpot had already composed a scathing takedown of NVIDIA's email: As a corporation, it's Nvidia's prerogative to decide on the reviewers it chooses to collaborate with. However, this and other related incidents raise serious questions around journalistic independence and what they are expecting of reviewers when they are sent products for an unbiased opinion...

In today's dynamic graphics hardware space, with 350W flagships, hardware ray tracing, and exotic cooling solutions, there's a wide range of data points Hardware Unboxed looks at. But at the end of the day, there's only one real question every GPU buyer wants to know: how well do games run on a particular piece of hardware? Considering that 99% percent of Steam games feature raster-only rendering pipelines, rasterization performance was, is, and will be, a key point that Steve considers in GPU reviews...

[M]ost games (including almost all RTX titles) are built on raster renderers. A hypothetical graphics card with most of its die space reserved for ray tracing would run Quake II RTX great and... not much else. Ray tracing absolutely deserves a place in modern GPU reviews. But there's simply not enough of it in enough games for any responsible reviewer to put it center-stage, in place of raster performance. It wouldn't do justice to consumers, who will primarily be running raster workloads. This is why Nvidia's complaint is so puzzling.

Mount Everest, Earth's Tallest Mountain, Just Got Taller By About a Meter 44

China and Nepal say they have determined the "most accurate height of Everest that we have ever had," calculating it to be about 8,848.86 meters (29,031.7 feet) high. That's almost a meter taller than the mountain's previous recognized height. CNET reports: The two countries, which border each other at the mountain's summit, shared the news in a joint virtual briefing Tuesday that was streamed live online. Nepal began remeasuring the mountain in 2017, and China began its own work after Chinese President Xi Jinping visited Nepal in 2019. As part of the complicated measurement, researchers placed signal receivers on the mountain and measured the amount of time it took signals to travel between the receiver and satellites to figure out the new height. Global positioning devices and ground-penetrating radar were also used. Nepal's lead surveyor Khimlal Gautam ended up with damaged toes due to frostbite he suffered while installing the measuring equipment.

A 2015 earthquake in Nepal helped inspire the re-measurement of Everest. The BBC notes that some geologists thought that quake could've shrunk the mountain's snow cap, while others note that Himalayan peaks can actually grow taller over time as shifting tectonic plates push them upward.

You Can Now Play an Ultra-Rare Quake Arcade Cabinet at Home (arstechnica.com) 17

Since its 1996 PC release, id's seminal shooter Quake has been ported to everything from flip phones and smartphones to game consoles and Web browsers. But even many serious fans of the series don't know about Quake Arcade Tournament Edition (Quake ATE), an officially licensed version of the game that ran on custom arcade cabinets. From a report: Even among those who know about it, few ever got a chance to play it during the brief time it was in arcades, and hardware-based DRM built into the cabinet meant the game wasn't playable on home emulators. That state of affairs now seems set to change thanks to the recent release of a Windows executable that can decrypt the data dumped from those aging arcade hard drives for play on a modern home computer.

Do Animals Really Anticipate Earthquakes? Sensors Hint They Do (scientificamerican.com) 41

An anonymous reader quotes Scientific American: For centuries, people have described unusual animal behavior just ahead of seismic events: dogs barking incessantly, cows halting their milk, toads leaping from ponds... Now researchers at the Max Planck Institute of Animal Behavior and the University of Konstanz, both in Germany, along with a multinational team of colleagues, say they have managed to precisely measure increased activity in a group of farm animals prior to seismic activity...

The researchers used highly sensitive instruments that record accelerated movements — up to 48 each second — in any direction. During separate periods totaling about four months in 2016 and 2017, they attached these biologgers and GPS sensors to six cows, five sheep and two dogs living on a farm in an earthquake-prone area of northern Italy. A total of more than 18,000 tremors occurred during the study periods, with more seismic activity during the first one — when a magnitude 6.6 quake and its aftershocks struck the region. The team's work was published in July in Ethology...

Analyzing the increased movements as a whole, the researchers claim, showed a clear signal of anticipatory behavior hours ahead of tremors. "It's sort of a system of mutual influence," Wikelski says. "Initially, the cows kind of freeze in place — until the dogs go crazy. And then the cows actually go even crazier. And then that amplifies the sheep's behavior, and so on...." This "swarm intelligence" can happen within or across species, Wikelski says. For example, "we did a study on Galápagos marine iguanas, and we know that they are actually listening in to mockingbirds' warnings about the Galápagos hawks," he adds. "These kinds of systems exist all over the place. We're just not really tuned in to them yet."

The researchers say the farm animals appeared to anticipate tremors anywhere from one to 20 hours ahead, reacting earlier when they were closer to the origin and later when they were farther away. This finding, the authors contend, is consistent with a hypothesis that animals somehow sense a signal that diffuses outward.

An Earthquake With a Preliminary Magnitude of 7.8 Struck Off the Coast of Alaska Early Wednesday Morning. (cnn.com) 34

An earthquake with a preliminary magnitude of 7.8 struck off the coast of Alaska early Wednesday morning. From a report: The earthquake was centered 60 miles, or 98 kilometers, south-southeast, of Perryville, Alaska, according to the US Geological Survey. The quake is considered shallow at about six miles, or 10 kilometers, deep. "Anything below 70 kilometers is considered a shallow quake," CNN meteorologist Allison Chinchar previously said. "That's important, because shallow earthquakes often cause the most damage, compared to the ones that are deeper, regardless of the strength." A tsunami warning had been issued following the earthquake, according to the National Oceanic and Atmospheric Administration. The warning was in effect for south Alaska and the Alaska peninsula -- Pacific coasts from Kennedy Entrance, Alaska (40 miles southwest of Homer) to Unimak Pass, Alaska, according to the Tsunami Warning Center. But all tsunami warnings and advisories were canceled early Wednesday morning, according to the National Weather Service.

Nvidia Engineer Releases Open-Sourced Vulkan Graphics Driver for the Raspberry Pi (tomshardware.com) 20

Long-time Slashdot reader frootcakeuk quotes an article from Hot Hardware: Earlier this year, the Raspberry Pi Foundation hooked up with Igalia to start development on an open-sourced Vulkan graphics driver for the Raspberry Pi. However, Martin Thomas, an engineer at Nvidia, beat them to the punch.

Thomas announced yesterday via his personal Twitter that his RPi-VK-Driver is ready for primetime. The talented engineer had been working on the Vulkan driver in his spare time for more than two years.

Technically, Thomas' iteration isn't a Vulkan driver per se because it doesn't comply with the official standards established by The Khronos Group. Nonetheless, the resourceful developer produced a driver that adheres to the Vulkan parameters as much as possible, and as close as the hardware would permit it. There's just one limitation with the RPi-VK-Driver though. Unlike the official Vulkan driver that's still in the works, Thomas' version is only compatible with the Broadcom VideoCore IV GPU that's found inside the Raspberry Pi 1, 2, 3 and Zero devices.

Mars Is a Seismically Active World, First Results From NASA's InSight Lander Reveal (space.com) 13

The first results from NASA's quake-hunting InSight Mars lander just came out, and they reveal that Mars is a seismically active planet. Space.com reports: Martian seismicity falls between that of the moon and that of Earth, [says InSight principal investigator Bruce Banerdt, of NASA's Jet Propulsion Laboratory]. "In fact, it's probably close to the kind of seismic activity you would expect to find away from the [tectonic] plate boundaries on Earth and away from highly deformed areas," he said. InSight's observations will help scientists better understand how rocky planets such as Mars, Earth and Venus form and evolve, mission team members have said. The mission's initial science returns, which were published today (Feb. 21) in six papers in the journals Nature Geoscience and Nature Communications, show that InSight is on track to meet that long-term goal, Banerdt said.

The new studies cover the first 10 months of InSight's tenure on Mars, during which the lander detected 174 seismic events. These quakes came in two flavors. One hundred and fifty of them were shallow, small-magnitude tremors whose vibrations propagated through the Martian crust. The other 24 were a bit stronger and deeper, with origins at various locales in the mantle, InSight team members said. (But even those bigger quakes weren't that powerful; they landed in the magnitude 3 to 4 range. Here on Earth, quakes generally must be at least magnitude 5.5 to damage buildings.) That was the tremor tally through September 2019. InSight has been busy since then as well; its total quake count now stands at about 450, Banerdt said. And all of this shaking does indeed originate from Mars itself, he added; as far as the team can tell, none of the vibrations were caused by meteorites hitting the Red Planet. So, there's a lot going on beneath the planet's surface.
What's interesting to note is that unlike Earth, where most quakes are caused by tectonic plates sliding around, Mars' quakes are caused by the long-term cooling of the planet since its formation 4.5 billion years ago. "As the planet cools, it contracts, and then the brittle outer layers then have to fracture in order to sort of maintain themselves on the surface," Banerdt said. "That's kind of the long-term source of stresses."

"A wealth of information can be gleaned from InSight's quake measurements," reports Space.com. "For example, analyses of how the seismic waves move through the Martian crust suggest there are small amounts of water mixed in with the rock, mission team members said." They can't say one way or the other whether there are large underground reservoirs of water at this point, but the research is convincing.

The new papers also mention a variety of other discoveries as well. "For example, InSight is the first mission ever to tote a magnetometer to the Martian surface, and that instrument detected a local magnetic field about 10 times stronger than would be expected based on orbital measurements," the report says. "InSight is also taking a wealth of weather data, measuring pressure many times per second and temperature once every few seconds. This information helps the mission team better understand environmental noise that could complicate interpretations of the seismic observations, but it also has considerable stand-alone value."

New Trailer, Gameplay Videos Released For Upcoming 'DOOM Eternal' (collider.com) 24

Id software has released a new trailer for their upcoming Doom sequel set on a demon-infested planet Earth in the year 2151. And GameSpot has uploaded a 10-minute clip of gameplay while Collider released 15 minutes.

Collider writes: Doom Eternal takes everything that was gloriously batshit about Doom 2016, throws it in a Lamborghini full of Slayer albums and catapults it into the sun. This game is out of its goddamn mind in the best possible way, and I literally cannot wait to get my hands on the full version... The Fortress of Doom is massive. I wasn't able to access every area, and could only guess at the function of some of the areas I did see. One section had the original Doom Marine costume on display in a glass case, and the game's director, Hugo Martin confirmed that the skin is an unlockable. Moreover, he indicated that there are several unlockable player skins in the game, including one he was clearly excited about but couldn't reveal, saying that it was still in the licensing approval stage...

Doom Eternal, like its predecessor, is a fast game, pitting you against hordes of powerful enemies that force you to constantly be on the move and quick-swapping weapons to inflict maximum damage while avoiding death. You have a few tools at your disposal to earn guaranteed life, ammo, and armor, which are the over-the-top glory kills, the terrifying chainsaw, and the brand-new flame belcher respectively. Glory kills are special instant-death maneuvers you can unleash on enemies after staggering them, and the addition of a retractable arm blade has heightened the graphic absurdity of them to such a degree that I was giggling like an idiot every time I pulled one off.

I spent the next three hours murdering my way across three massive levels that were incredibly varied in terms of design, beginning in a blasted post-apocalyptic city, then moving to a vast overgrown temple, and finally ending up in a heavily-fortified arctic base... Each stage had a completely different feel -- the city was very ground-based, with dark subway tunnels and skeletal office buildings. The temple was spread out across what felt like miles, with an unexpected amount of verticality and traversal thanks to the new climbing mechanic. Yep, Doom Guy can now cling to certain walls, as well as swing from poles to extend his jump and gain access to distant ledges. The climbing controls are a bit funky, like Spider-Man with a rotator cuff injury, but the traversal puzzles are fun and satisfying, and allow for some truly massive environments...

Martin promised that players will continue to be introduced to new enemies and environments right up until the end of the 22+ hour campaign. He describes Doom Eternal as a thinking person's action game, and that the team's goal was to create a combat puzzle worth your time.

DOOM Eternal is scheduled to be released on March 20th.

Ubisoft Uses AI To Teach a Car To Drive Itself in a Racing Game (venturebeat.com) 14

An anonymous reader shares a report: Reinforcement learning, an AI training technique that employs rewards to drive software policies toward goals, has been applied successfully to domains from industrial robotics to drug discovery. But while firms including OpenAI and Alphabet's DeepMind have investigated its efficacy in video games like Dota 2, Quake III Arena, and StarCraft 2, few to date have studied its use under constraints like those encountered in the game industry. That's presumably why Ubisoft La Forge, game developer Ubisoft's eponymous prototyping space, proposed in a recent paper an algorithm that's able to handle discrete, continuous video game actions in a "principled" and predictable way. They set it loose on a "commercial game" (likely The Crew or The Crew 2, though neither is explicitly mentioned) and report that it's competitive with state-of-the-art benchmark tasks.

"Reinforcement Learning applications in video games have recently seen massive advances coming from the research community, with agents trained to play Atari games from pixels or to be competitive with the best players in the world in complicated imperfect information games," wrote the coauthors of a paper describing the work. "These systems have comparatively seen little use within the video game industry, and we believe lack of accessibility to be a major reason behind this. Indeed, really impressive results ... are produced by large research groups with computational resources well beyond what is typically available within video game studios." The Ubisoft team, then, sought to devise a reinforcement learning approach that'd address common challenges in video game development. They note that data sample collection tends to be a lot slower generally, and that there exist time budget constraints over the runtime performance of agents.

Xiaomi Integrates Earthquake Alert System Into MIUI OS (techcrunch.com) 9

Xiaomi today unveiled a new iteration of its virtual assistant Xiao Ai and shared a new feature of Android-based MIUI operating system as the publicly listed Chinese technology group pushes to expand its internet services ecosystem. From a report: At its annual Mi Developer conference in Beijing, the company said it is integrating an earthquake warning function into MIUI for select users in China, with plans to expand it nationwide soon. The integration, touted as the first of its kind globally, will enable alerts to be sent to smartphones running MIUI 11 and Mi TV "seconds to tens of seconds" before the quake waves arrive, Xiaomi said. The feature, which was first tested in September this year, has been developed in partnership with Institute of Care-life, a Chengdu-based organization focusing on natural disaster warning. Xiaomi said it has activated the feature for the earthquake-prone Sichuan Province and plans to expand it elsewhere in the nation soon. Wang Tun, head of the institute, said this function, unlike those available through apps in some countries, works more efficiently and does not rely on a working internet connection.

California Launches First Statewide Earthquake Early Warning System (buzzfeednews.com) 17

hcs_$reboot writes: Everyone in California will now receive earthquake alerts on their phones seconds before the ground begins to shake, giving residents up to 20 seconds of warning before shaking begins. Developed by seismologists at the University of California, Berkeley, the MyShake application (residents will need to download the app to receive the alerts in areas without cell phone coverage) is designed to alert the public when a magnitude 4.5 earthquake or greater has been detected and has been shown to be faster than other alert delivery methods. The wireless emergency alerts will be sent in the event of a more significant quake, magnitude 5.0 or greater. The system does not predict earthquakes. Rather, it uses numerous seismic stations to detect the start of an earthquake and light-speed communications to send the data to computers that instantly calculate location, magnitude, intensity of shaking and create alerts to be distributed to areas that will be affected. When the MyShake app was released back in 2016 it already detected over 200 earthquakes in more than ten countries.

A paper describing the early results gives a general idea of the app's success: "On a typical day about 8,000 phones provide acceleration waveform data to the MyShake archive. The on-phone app can detect and trigger on P waves and is capable of recording magnitude 2.5 and larger events. The largest number of waveforms from a single earthquake to date comes from the M5.2 Borrego Springs earthquake in Southern California, for which MyShake collected 103 useful three-component waveforms. The network continues to grow with new downloads from the Google Play store everyday and expands rapidly when public interest in earthquakes peaks such as during an earthquake sequence."

NVIDIA's Job Listings Reveal 'Game Remastering' Studio, New Interest In RISC-V (forbes.com) 40

An anonymous reader quotes Forbes: Nvidia has a lot riding on the success of its GeForce RTX cards. The Santa Clara, California company is beating the real-time ray tracing drum loudly, adamant on being known as a champion of the technology before AMD steals some of its thunder next year with the PlayStation 5 and its own inevitable release of ray-tracing enabled PC graphics cards.

Nvidia has shown that, with ray tracing, it can breathe new life into a decades-old PC shooter like id Software's Quake 2, so why not dedicate an entire game studio to remastering timeless PC classics? A new job listing spotted by DSOGaming confirms that's exactly what Nvidia is cooking up.

The ad says NVIDIA's new game remastering program is "cherry-picking some of the greatest titles from the past decades and bringing them into the ray tracing age, giving them state-of-the-art visuals while keeping the gameplay that made them great." (And it adds that the initiative is "starting with a title that you know and love but we can't talk about here!")

Meanwhile, a China-based industry watcher on Medium reports that "six RISC-V positions have been advertised by NVIDIA, based in Shanghai and pertaining to architecture, design, and verification."

NASA Mic'd Up Mars and Uploaded It To Soundcloud (vice.com) 23

On Tuesday, NASA posted several sonifications of data captured on Mars by InSight, a robotic lander that touched down on the red planet last year. From a report: InSight is the first mission ever to record "marsquakes" the Martian equivalent of earthquakes, which it detects with an instrument called Seismic Experiment for Interior Structure (SEIS), made by the French space agency. SEIS has now heard about 100 weird tremors rippling through the interior of Mars, 21 of which have been identified as likely marsquakes. For instance, here's an audio representation of a magnitude 3.7 marsquake detected on May 22, 2019, which was SEIS' 173th "sol" (the word for a Martian day) of operation. NASA dialed the seismic frequencies recorded by SEIS up to a range that can be heard by the human ear, but you may still need headphones to get the full experience. The quake sounds a bit like the kind of ambient bass-heavy hum you might expect to play during a tense scene in a movie thriller.

AI Takes On Earthquake Prediction (quantamagazine.org) 13

After successfully predicting laboratory earthquakes, a team of geophysicists has applied a machine learning algorithm to quakes in the Pacific Northwest. From a report: In May of last year, after a 13-month slumber, the ground beneath Washington's Puget Sound rumbled to life. The quake began more than 20 miles below the Olympic mountains and, over the course of a few weeks, drifted northwest, reaching Canada's Vancouver Island. It then briefly reversed course, migrating back across the U.S. border before going silent again. All told, the monthlong earthquake likely released enough energy to register as a magnitude 6. By the time it was done, the southern tip of Vancouver Island had been thrust a centimeter or so closer to the Pacific Ocean. Because the quake was so spread out in time and space, however, it's likely that no one felt it. These kinds of phantom earthquakes, which occur deeper underground than conventional, fast earthquakes, are known as "slow slips." They occur roughly once a year in the Pacific Northwest, along a stretch of fault where the Juan de Fuca plate is slowly wedging itself beneath the North American plate.

More than a dozen slow slips have been detected by the region's sprawling network of seismic stations since 2003. And for the past year and a half, these events have been the focus of a new effort at earthquake prediction by the geophysicist Paul Johnson. Johnson's team is among a handful of groups that are using machine learning to try to demystify earthquake physics and tease out the warning signs of impending quakes. Two years ago, using pattern-finding algorithms similar to those behind recent advances in image and speech recognition and other forms of artificial intelligence, he and his collaborators successfully predicted temblors in a model laboratory system -- a feat that has since been duplicated by researchers in Europe. Now, in a paper posted this week on the scientific preprint site arxiv.org, Johnson and his team report that they've tested their algorithm on slow slip quakes in the Pacific Northwest. The paper has yet to undergo peer review, but outside experts say the results are tantalizing. According to Johnson, they indicate that the algorithm can predict the start of a slow slip earthquake to "within a few days -- and possibly better."

'Doom' Celebrates 25th Anniversary By Re-Releasing Three Classic Games (theverge.com) 102

To celebrate the 25th anniversary of Doom, there's now mobile versions in the Google Play Store, reports Android Police, "and since this is a 25th-anniversary release, it includes the fourth expansion Thy Flesh Consumed. It's the complete package folks, and it's finally available on Android as an official release."

And in addition, three Doom re-releases are now available for the Nintendo Switch, Xbox One, and PlayStation 4, reports the Verge -- though there was one little glitch: Bethesda says it'll get rid of the strange requirement that players must log into an online account before they play the newly re-released versions of Doom, Doom II, and Doom 3, which went live yesterday. Players quickly criticized Bethesda for the seemingly ridiculous limitation -- the first of these games was released more than 25 years ago, at a time when there was obviously no internet requirement. The online login will be made optional in a coming update, Bethesda said today.
The re-releases were part of QuakeCon 2019, reports IGN, noting that Bethesda also showcased Doom Eternal's multiplayer, "revealing new details about the unique 1v2 Battle Mode."

Forbes hails the re-releases as "id Software's fast-paced, ultra-violent...classic shooters," adding that "It appears the re-releases are actually Unity remakes, though whether much has changed beyond resolution support remains to be seen." But they may also have some other minor differences, Engadget reports: There have been a few other complaints as well, such as the addition of copy protection, graphical changes (such as filtering that softens those 1993-era graphics) and apparent music tempo slowdowns on the Switch. That's not including the removal of downloads for the old PS3 and Xbox 360 versions. It's not a fiasco, but these clearly weren't the straightforward ports some were expecting.

California Earthquake Brings Scattered Damage (cnn.com) 84

The strongest earthquake to hit Southern California in 20 years left scattered damage Thursday morning and was felt from Las Vegas to Orange County, the US Geological Survey reported. From a report: The quake, with an early magnitude of 6.4, was centered near Ridgecrest, a community west of the Mojave Desert and about 150 miles north of Los Angeles. Reports of scattered damage, including rock slides and fires, rolled in by midday. At least four large aftershocks, from 3.5 to 4.7 magnitude, and dozens smaller were recorded, officials said. In Los Angeles, the temblor was felt as a long, rolling quake, and buildings rocked back and forth for at least several seconds. Before Thursday, the largest quake in the area was in 1999 near Barstow, said seismologist Lucy Jones of the USGS. Diane Ruggiero, general manager of the Hampton Inn and Suites Ridgecrest in Ridgecrest, told CNN's Paul Vercammen that the hotel has significant damage.
