An anonymous reader quotes a report from ZDNet: In the latest Top 500 supercomputer ratings, the average speed of these Linux-powered racers is now an astonishing 1.14 petaflops. The fastest of the fast machines haven't changed since the June 2019 Top 500 supercomputer list. Leading the way is Oak Ridge National Laboratory's Summit system, which holds top honors with an HPL result of 148.6 petaflops. This is an IBM-built supercomputer using Power9 CPUs and NVIDIA Tesla V100 GPUs. In a rather distant second place is another IBM machine: Lawrence Livermore National Laboratory's Sierra system. It uses the same chips, but it "only" hit a speed of 94.6 petaflops.

Close behind at No. 3 is the Sunway TaihuLight supercomputer, with an HPL mark of 93.0 petaflops. TaihuLight was developed by China's National Research Center of Parallel Computer Engineering and Technology (NRCPC) and is installed at the National Supercomputing Center in Wuxi. It is powered exclusively by Sunway's SW26010 processors. Sunway's followed by the Tianhe-2A (Milky Way-2A). This is a system developed by China's National University of Defense Technology (NUDT). It's deployed at the National Supercomputer Center in China. Powered by Intel Xeon CPUs and Matrix-2000 accelerators, it has a top speed of 61.4 petaflops. Coming at No. 5, the Dell-built, Frontera, a Dell C6420 system is powered by Intel Xeon Platinum processors. It speeds along at 23.5 petaflops. It lives at the Texas Advanced Computing Center of the University of Texas. The most powerful new supercomputer on the list is Rensselaer Polytechnic Institute Center for Computational Innovations (CCI)'s AiMOS. It made the list in the 25th position with 8.0 petaflops. The IBM-built system, like Summit and Sierra, is powered by Power9 CPUs and NVIDIA V100 GPUs. In closing, ZDNet's Steven J. Vaughan-Nichols writes: "Regardless of the hardware, all 500 of the world's fastest supercomputers have one thing in common: They all run Linux."

"It's here! Purism announces shipment of the Librem 5," writes long-time Slashdot reader Ocean Consulting: Librem 5 is a landmark mobile device with a dedicated platform, runs PureOS Linux, and is the first mobile phone to seek hardware certification from the Free Software Foundation. Initially a crowd sourced funding campaign, the phone embraces principles of free software and user privacy. IP native communication is supported via Matrix. Privacy features include hardware kill switches for camera, microphone, cellular, wifi, Bluetooth and GPS.
"The Librem 5 phone is built from the ground up to respect the privacy, security, and freedoms of society," reads the site's official announcement. "It is a revolutionary approach to solving the issues that people face today around data exploitation -- putting people in control of their own digital lives."

They're adopting an "iterative" shipping schedule -- publishing a detailed schedule defining specific batches and their features with corresponding shipping dates. "Each iteration improves upon the prior in a rapid rolling release throughout the entire first version of the phone... As slots in a particular early batch free up, we will open it up for others in a later batch to join in, according to the date of the order."

An anonymous reader writes: Apple will launch three new iPhone models in an event next week. Two will be called "Pro" models and will replace the iPhone XS and XS Max. A third phone will replace the iPhone XR and will include dual cameras, Bloomberg reported Thursday. The Pro iPhones will feature triple rear cameras that will include a wide-angle lens, support for higher resolution photos, better low light performance, and better video recording capabilities. These Pro phones will also support reverse wireless charging similar to what Samsung offers with the Galaxy S10. This will allow the phones to charge the AirPods when used with their wireless charging case. Other details include a new, multi-angle, Face ID sensor which will allow the phone to sense your face while lying flat on a table, better waterproofing, and new shatter-resistance technology. Bloomberg doesn't specify which of the new models these features will come to. All the phones will reportedly include a faster A13 processor, as well as a new Matrix chip that could benefit computer vision and augmented reality performance. Outside of a new matte-colored finish, the Pro phones will look broadly similar to last year's models. 3D Touch has reportedly been dropped from all of this year's models and replaced with the Haptic Touch system that debuted with the iPhone XR last year.

Apple is also planning to release new 11-inch and 12.9-inch iPad Pros this year. Bloomberg says these will feature "upgraded cameras," although it doesn't mention whether they will have more than one camera on their rear. Faster processors are also expected, but their overall appearance will apparently remain the same. Bloomberg claims that Apple will discontinue its existing entry-level 9.7-inch iPad in favor of a new 10.2-inch model. Apple's 2019 MacBook Pros Bloomberg's report also corroborates previous rumors about Apple launching a new 16-inch MacBook Pro this year. The new laptop will reportedly be similar in size overall to the existing 15-inch MacBook Pro, but will be able to include a bigger screen because of a reduction in the size of its screen bezels.

Lana Wachowski is set to write and direct a fourth film set in the world of "The Matrix," with Keanu Reeves and Carrie-Anne Moss reprising their roles as Neo and Trinity, respectively. Variety reports: Warner Bros. Pictures and Village Roadshow Pictures will produce and globally distribute the film. In addition to Wachowski, the script was also written by Aleksandar Hemon and David Mitchell. Wachowski is also producing with Grant Hill. Sources say the film is eyed to begin production at the top of 2020. Warner Bros. has been trying for the last of couple years to find a way to get back into "The Matrix" universe, but a hold-up over producing rights slowed the project down. Over the past couple of months, the studio saw an opportunity to ramp up development, with Reeves boasting a strong summer that included box office hits "John Wick 3"; and "Toy Story 4" and a script from Wachowski that drummed up excitement. Plot details are currently unknown, as is how the role of Morpheus will be handled, originally played by Laurence Fishburne. Some sources say the role may be recast for a younger take.

In 2014 Esquire argued that great movies like The Matrix "predicted a revolution in film that never happened," adding "We are in many ways worse off now than we were 15 years ago as a culture. We seem to have run out of original ideas."

This week two film critics debated whether 1999 was in fact cinema's last great year. Slashdot reader dryriver writes: Notable films of 1999 are Fight Club, Magnolia, The Matrix, Eyes Wide Shut, Three Kings, The Sixth Sense, EXistenZ, Being John Malkovich, Man On The Moon, American Beauty, The Talented Mr. Ripley, Office Space, Boys Don't Cry, Election, Rushmore, Buena Vista Social Club, The Virgin Suicides, Sleepy Hollow, The Insider, Girl Interrupted, The Iron Giant and Toy Story 2.

According to Nicholas Barber, 1999 also was the beginning of the end for quality cinema:

"The release of Star Wars: Episode I: The Phantom Menace proved that long-dormant series could be lucratively revived. Toy Story 2, the first ever Pixar sequel, proved that cartoon follow-ups needn't be straight-to-video cheapies, but major, money-spinning phenomena. The Matrix proved that digitally-enhanced superhero action could attract audiences of all ages. And The Blair Witch Project proved that found-footage horror in particular, and microbudget horror in general, could be a gold mine. As wonderful as those films may have been -- The Phantom Menace excepted, obviously -- they taught Hollywood some toxic lessons. Instead of continuing to bet on young mavericks, studio executives twigged that there was a fortune to be made from superhero blockbusters, Disney sequels, merchandise-friendly franchises and cheapo horror movies. And that's what we get in 2019, week after week."
He also writes that the boom in DVDs in 1999 had "encouraged studios to fund offbeat projects," ultimately concluding 1999 was "the year when everything began to go wrong." He argues that today it's a different technology driving innovation. "In the 21st Century, streaming platforms have made the small screen the home of fresh ideas, as well as for conversation-starting communal cultural experiences."

But film critic Hannah Woodhead counters with a line from the 1999 film Magnolia: "We may be through with the past, but the past ain't through with us."

"Nostalgia is often the enemy of progress when it comes to pop culture. We have a tendency to look back fondly on what came before, ironing out the flaws in our memory until the past is something that seems truly great, and even aspirational."

An anonymous reader shares a post: Like many things that starts out as a mere annoyance, though eventually growing into somewhat of an affliction. One particularly dark and insidious thing has more than reared its ugly head in recent years, and now far more accurately described as an epidemic disease. I'm talking about the filth that is reCAPTCHA. Yes that seemingly harmless question of "Are you a human?" Truly I wish all this called for were sarcastic puns of 'The Matrix' variety but the matter is far more serious. Google describes reCAPTCHA as: "[reCAPTCHA] is a free security service that protects your websites from spam and abuse." However, this couldn't be further from the truth, as reCAPTCHA is actually something that causes abuse. In fact, I would go so far as to say that being subjected to constant reCAPTCHAs is actually an act of human torture and disregard for a person's human right of mental comfort. The author goes on to make several points.

From a blog post: Classic USB from the 1.1, 2.0, to 3.0 generations using USB-A and USB-B connectors have a really nice property in that cables were directional and plugs and receptacles were physically distinct to specify a different capability. A USB 3.0 capable USB-B plug was physically larger than a 2.0 plug and would not fit into a USB 2.0-only receptacle. For the end user, this meant that as long as they have a cable that would physically connect to both the host and the device, the system would function properly, as there is only ever one kind of cable that goes from one A plug to a particular flavor of B plug. Does the same hold for USB-C? Sadly, the answer is no. Cables with a USB-C plug on both ends (C-to-C), hitherto referred to as "USB-C cables", come in several varieties. Here they are, current as of the USB Type-C Specification 1.4 on June 2019:
USB 2.0 rated at 3A,
USB 2.0 rated at 5A,
USB 3.2 Gen 1 (5gbps) rated at 3A,
USB 3.2 Gen 1 (5gbps) rated at 5A,
USB 3.2 Gen 2 (10gbps) rated at 3A,
and USB 3.2 Gen 2 (10gpbs) rated at 5A.

We have a matrix of 2 x 3, with 2 current rating levels (3A max current, or 5A max current), and 3 data speeds (480mbps, 5gbps, 10gpbs). Adding a bit more detail, cables 3-6, in fact, have 10 more wires that connect end-to-end compared to the USB 2.0 ones in order to handle SuperSpeed data rates. Cables 3-6 are called "Full-Featured Type-C Cables" in the spec, and the extra wires are actually required for more than just faster data speeds. "Full-Featured Type-C Cables" are required for the most common USB-C Alternate Mode used on PCs and many phones today, VESA DisplayPort Alternate Mode. VESA DP Alt mode requires most of the 10 extra wires present in a Full-Featured USB-C cable.

An anonymous reader quotes VentureBeat: CD Projekt Red showed off a new demo of Cyberpunk 2077 at Microsoft's Xbox press event at the Electronic Entertainment Expo, the big game trade show in Los Angeles. And actor Keanu Reeves surprised everyone by coming out on stage to say that he would be in it. The trailer reveals one of the key characters of Cyberpunk 2077, Johnny Silverhand. The legendary rockerboy is played by Reeves (The Matrix trilogy, John Wick series, Johnny Mnemonic). In addition to his appearance and voice, Reeves is also providing full-body motion capture for the character. The game debuts on April 16, 2020...

We all know that CD Projekt Red has a hell of a game in Cyberpunk 2077, which the company revealed in a 48-minute gameplay video last year. The video showed an amazingly detailed open world, as the narrator said the ambition was to create "the most believable city in any open world to date." I interpreted that as a shot across the bow of Rockstar Games and the Grand Theft Auto and Red Dead Redemption teams, as Cyberpunk 2077 was as incredibly hyper detailed as any Rockstar game I've ever seen. It's the only game I've seen with such density of interaction and the realism integrity of Grand Theft Auto V and Red Dead Redemption 2....

Last year's demo of the upcoming game promised deeper the details of the open world, with fascinating futuristic touches such as cranial chip implants, robotic body modifications, hyperfast video communications, and surveillance drones. The dystopic city seemed like a living thing, and the choices for getting things done seemed like they had no limits. You could be as peaceful or violent as you wished... It's a mature game, aimed at adults who can deal with subjects like nudity, drugs, and murder.

hackingbear shares a report from CNN: A team of researchers from Zhejiang University School of Medicine in Hangzhou, China, created a gel composed of a network of proteins, inspired by the matrix composition of human connective tissues, and other molecules. The product, which requires ultraviolet light to activate, can adhere within seconds and then bond to wet biological tissue surfaces without suturing. In pigs, the bio-glue sealed a punctured carotid artery, a major blood vessel in the neck, in less than a minute and also filled holes in the cardiac wall. The Chinese researchers monitored their post-surgical pigs for a two-week recovery period and saw natural healing with no abnormalities or unusual inflammation. Around the globe, more than 234 million surgeries are performed each year, the World Health Organization estimates. Additional research confirming the safety of this product is needed before experiments can begin in humans, according to the authors of a study published Wednesday in the journal Nature Communications.

"The equation is simple: The heavier the plane, the more environmentally unfriendly the trip is," notes one report -- yet airplanes are still relying on estimates for their total weight.

"A British tech start-up thinks it has a solution: weighing customers to more accurately calculate fuel costs..." "The capture of passenger weights is not complicated," says Roy Fuscone, Chairman & CEO of Fuel Matrix Limited. "A simple weighing device added to the current equipment will capture the weight and the software will register and transmit it in relation to a flight but not necessarily identified to a particular passenger...." The company's website states that benefits from this system include statistically robust information feedback based on airlines' data, significant reduction of CO2 emissions, significant fuel savings, and reduced mechanical stress on aircraft. If you're worried about this data being made public, Fuscone says that the company plans to enable the passenger to retain direct control of their own data so that they can delete it once it has been "employed in the interests of fuel efficiency."
It seems like it'd be easier to just weigh the plane after everyone's onboard -- or find some way to calculate weights using the boarding ramp. But the current plans aren't that simple, CNN reports: One proposal is for passengers to supply the information ahead of arriving at the airport, in the same way that they supply passport details. Otherwise, it could be made part of the security process before boarding. "You stand in a scanner that goes round you -- now, clearly while you're standing there being scanned, you could also be being weighed -- very discreetly -- if you haven't wanted to supply your information ahead of time," says Fuel Matrix CEO Roy Fuscone. "It would be very discreet, very private and very confidential."

Fuscone stresses that Fuel Matrix has been working with GDPR consultants to ensure the data would remain classified. He points out that airports already collect a lot of information on passengers. This would be just one more element to the equation. "Airports already use biometric data on passengers because they associate an image of your face with your boarding card, so that means that when you buy a ticket it's already in the contract that they can do that," says Fuscone. "So there's no problem with us introducing this, it can be done at various places during the journey through the airport and so we're starting to discuss with people involved in those various phases of the airport. If this is all done properly [...] it will alleviate carbon in the atmosphere and climate change and air pollution."

Researchers have 3D-printed a heart using a patient's cells, providing hope that the technique could be used to heal hearts or engineer new ones for transplants. "This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers," Professor Tal Dvir of Tel Aviv University's School of Molecular Cell Biology and Biotechnology said in a statement. Dvir is senior author of the research, published Monday in the journal Advanced Science. CNN reports: The process of printing the heart involved a biopsy of the fatty tissue that surrounds abdominal organs. Researchers separated the cells in the tissue from the rest of the contents, namely the extracellular matrix linking the cells. The cells were reprogrammed to become stem cells with the ability to differentiate into heart cells; the matrix was processed into a personalized hydrogel that served as the printing "ink."

The cells and hydrogel were first used to create heart patches with blood vessels and, from there, an entire heart. Next, the researchers plan to train the hearts to behave like hearts, Dvir explained. "The cells need to form a pumping ability; they can currently contract, but we need them to work together." If researchers are successful, they plan to transplant the 3D-printed heart in animal models and, after that, humans.

Canada is the newest frontier in the fight for the "right to repair" after an Ontario politician introduced a bill on Thursday that would ensure individuals and independent professionals can repair brand-name computers and phones cheaply and easily. From a report: Manufacturers make it incredibly difficult to repair our broken devices ourselves. Instead of taking a smashed phone to a local repair professional for an affordable fix, a complex matrix of trade secrets and government intervention often means consumers have to make a pricey trip to the Genius Bar or buy a new device entirely. This is bad for your wallet, but also bad for the planet.

Ontario Liberal Party MPP Michael Coteau ran into this issue head-first after his daughter dropped his Samsung smartphone. An official repair job from the manufacturer was more expensive than just getting a new phone from his carrier, he told me over the phone. "It's a shame," Coteau said, "because the Samsung S8 was very good for me. Everything was perfect. I would've kept using it. But now I've replaced it." On Thursday, Coteau introduced a private member's bill in provincial parliament that, if passed, would be the first "right to repair" law for electronic devices in North America. More than a dozen US states are currently considering similar bills, but nothing is on the books yet in the US or in Canada.

A Beijing-based online education start-up has developed an artificial intelligence-powered maths app that can check children's arithmetic problems through the simple snap of a photo. Based on the image and its internal database, the app automatically checks whether the answers are right or wrong. From a report: Known as Xiaoyuan Kousuan, the free app launched by the Tencent Holdings-backed online education firm Yuanfudao, has gained increasing popularity in China since its launch a year ago and claims to have checked an average of 70 million arithmetic problems per day, saving users around 40,000 hours of time in total. Yuanfudao is also trying to build the country's biggest education-related database generated from the everyday experiences of real students. Using this, the six-year-old company -- which has a long line of big-name investors including Warburg Pincus, IDG Capital and Matrix Partners China -- aims to reinvent how children are taught in China. "By checking nearly 100 million problems every day, we have developed a deep understanding of the kind of mistakes students make when facing certain problems," said Li Xin, co-founder of Yuanfudao -- which means "ape tutor" in Chinese -- in a recent interview. "The data gathered through the app can serve as a pillar for us to provide better online education courses."

Volkswagen will spend $800 million to expand a U.S. factory that will produce the automaker's next generation of electric vehicles. "The factory in Chattanooga, Tenn. will be the company's North American base for manufacturing electric vehicles," reports TechCrunch. "The expansion is expected to create 1,000 jobs at the plant." From the report: VW's Chattanooga expansion is just a piece of the automaker's broader plan to move away from diesel in the wake of the emissions cheating scandal that erupted in 2015. Globally, VW Group plans to commit almost $50 billion through 2023 toward the development and production of electric vehicles and digital services. The Volkswagen brand (so not including its Audi or Porsche brands) alone has forecasted selling 150,000 EVs by 2020 worldwide, increasing that number to 1 million by 2025.

The Tennessee factory (along with the other new facilities) will produce EVs using Volkswagen's modular electric toolkit chassis, or MEB, introduced by the company in 2016. The MEB is a flexible modular system -- really a matrix of common parts -- for producing electric vehicles that VW says make it more efficient and cost-effective. Electric vehicle production at the Tennessee site will begin in 2022. However, Volkswagen of America says it will offer the first EV based on the MEB platform to customers in 2020.This EV will be a series-production version of the I.D. CROZZ SUV concept that was first shown at the North American International Auto Show last year. This vehicle will have the interior space of a midsize SUV in the footprint of a compact SUV. Volkswagen of America will also offer a multi-purpose EV based off the I.D. BUZZ concept. This EV will be a series-production version of the I.D.

MIT chemical engineers have reportedly designed a material that can react with carbon dioxide from the air, "to grow, strengthen, and even repair itself." According to MIT News, "The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself." From the report: The current version of the new material is a synthetic gel-like substance that performs a chemical process similar to the way plants incorporate carbon dioxide from the air into their growing tissues. The material might, for example, be made into panels of a lightweight matrix that could be shipped to a construction site, where they would harden and solidify just from exposure to air and sunlight, thereby saving on the energy and cost of transportation. The material the team used in these initial proof-of-concept experiments did make use of one biological component -- chloroplasts, the light-harnessing components within plant cells, which the researchers obtained from spinach leaves. The chloroplasts are not alive but catalyze the reaction of carbon dioxide to glucose. Isolated chloroplasts are quite unstable, meaning that they tend to stop functioning after a few hours when removed from the plant. In their paper, [the researchers] demonstrate methods to significantly increase the catalytic lifetime of extracted chloroplasts. In ongoing and future work, the chloroplast is being replaced by catalysts that are nonbiological in origin.

The material the researchers used, a gel matrix composed of a polymer made from aminopropyl methacrylamide (APMA) and glucose, an enzyme called glucose oxidase, and the chloroplasts, becomes stronger as it incorporates the carbon. It is not yet strong enough to be used as a building material, though it might function as a crack filling or coating material, the researchers say. The team has worked out methods to produce materials of this type by the ton, and is now focusing on optimizing the material's properties. Commercial applications such as self-healing coatings and crack filling are realizable in the near term, they say, whereas additional advances in backbone chemistry and materials science are needed before construction materials and composites can be developed.

United Therapeutics, a startup that sells drugs to treat lung ailments, plans to use a 3-D printer to manufacture human lungs in "unlimited quantities." Bioprinting isn't a new idea. 3-D printers can make human skin, even retinas. Yet the method has been limited to tissues that are very small or very thin and lack blood vessels. From a report: United instead is developing a printer that it believes will be able, within a few years, to manufacture a solid, rubbery outline of a lung in exquisite detail, including all 23 descending branches of the airway, the gas-exchanging alveoli, and a delicate network of capillaries. A lung made from collagen won't help anyone: it's to a real lung what a rubber chicken is to an actual hen. So United is also developing ways to impregnate the matrix with human cells so they'll attach and burrow into it, bringing it alive.

[...] United has already made some risky organ bets. One of its subsidiaries, Revivicor, supplies surgeons with hearts, kidneys, and lungs from genetically engineered pigs (these have been used in baboons, so far). Another, Lung Bioengineering, refurbishes lungs from human donors by pumping warm solution into them. About 250 people have already received lungs that would otherwise have been designated medical waste. Don't expect fully manufactured organs soon. United, in its company projections, predicts it won't happen for another 12 years. United CEO Martine Rothblatt acknowledges that the printed structure I saw is just a start. "It's only two branches and no cells," she says.

Materials-science researchers are finding that plant fibres can add durability and strength to substances already used in the construction of buildings and in goods that range from toys and furniture to cars and aircraft. From a report: A big bonus is that, because plants lock up carbon in their structure, using their fibres to make things should mean less carbon dioxide is emitted. The production of concrete alone represents some 5% of man-made global CO{-2} emissions, and making 1kg of plastic from oil produces 6kg of the greenhouse gas. Start with the carrots. These are being investigated by Mohamed Saafi at Lancaster University, in England. Dr Saafi and his colleagues do not use whole carrots, but rather what they call "nanoplatelets" that have been extracted from carrots discarded by supermarkets or as waste from food-processing factories. Sugar-beet peelings are also a useful source of nanoplatelets.

The researchers are working with CelluComp, a British firm that produces such platelets for industrial applications, including as an additive that helps toughen the surface of paint as it dries. Each platelet is only a few millionths of a metre across. It consists of a sheet of stiff cellulose fibres. Although the fibres are minute, they are strong. By combining platelets with other materials a powerful composite can be produced. Dr Saafi is mixing the platelets into cement, which is made by burning limestone and clay together at high temperature. To turn cement into concrete it is mixed with aggregates such as sand, stones and crushed rocks, which act as reinforcement, and with water, which reacts with the chemicals in the cement to form a substance called calcium silicate hydrate. This starts off as a thick gel, but then hardens into a solid matrix that binds the aggregates together.

A scientific paper, originally published in March, from peer-reviewed journal Progress in Biophysics and Molecular Biology has found its way in this week's news-cycle. The paper, which is co-written by 33 authors including molecular immunologist Edward Steele and astrobiologist Chandra Wickramasinghe, suggests that octopuses could be aliens, adding legitimacy to a belief, which otherwise has been debunked several times in the recent years.

An excerpt from the paper, which makes the bold claim: The genetic divergence of Octopus from its ancestral coleoid sub-class is very great ... Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch color and shape are just a few of the striking features that appear suddenly on the evolutionary scene. [...] It is plausible then to suggest they [octopuses] seem to be borrowed from a far distant 'future' in terms of terrestrial evolution, or more realistically from the cosmos at large."Ephrat Livni of Quartz questions the basis of the finding: To make matters even more strange, the paper posits that octopuses could have arrived on Earth in "an already coherent group of functioning genes within (say) cryopreserved and matrix protected fertilized octopus eggs." And these eggs might have "arrived in icy bolides several hundred million years ago." The authors admit, though, that "such an extraterrestrial origin...of course, runs counter to the prevailing dominant paradigm." Indeed, few in the scientific community would agree that octopuses come from outer space. But the paper is not just about the provenance of cephalopods. Its proposal that octopuses could be extraterrestrials is just a small part of a much more extensive discussion of a theory called "panspermia," which has its roots in the ideas of ancient Greece. Newsweek spoke with Avi Loeb, the Frank B. Baird Jr. Professor of Science at Harvard University, who told the publication that the paper has raised "an interesting but controversial possibility." However, he added, that it offers no "indisputable proof" that the Cambrian explosion is the result of panspermia.

Further reading: Cosmos magazine has outlined some flaws in the assumptions that the authors made in the paper. It has also looked into the background of some of the authors. The magazine also points out that though the paper has made bold claims, it has yet to find support or corroboration from the scientific community. News outlet Live Science has also questioned the findings.

"Robot brains will challenge the fundamental assumptions of how we humans do things," argues Popular Mechanics, noting that age-old truism "that computers will always do literally, exactly what you tell them to." A paper recently published to ArXiv highlights just a handful of incredible and slightly terrifying ways that algorithms think... An AI project which pit programs against each other in games of five-in-a-row Tic-Tac-Toe on an infinitely expansive board surfaced the extremely successful method of requesting moves involving extremely long memory addresses which would crash the opponent's computer and award a win by default...

These amusing stories also reflect the potential for evolutionary algorithms or neural networks to stumble upon solutions to problems that are outside-the-box in dangerous ways. They're a funnier version of the classic AI nightmare where computers tasked with creating peace on Earth decide the most efficient solution is to exterminate the human race. The solution, the paper suggests, is not fear but careful experimentation.
The paper (available as a free download) contains 27 anecdotes, which its authors describe as a "crowd-sourced product of researchers in the fields of artificial life and evolutionary computation. Popular Science adds that "the most amusing examples are clearly ones where algorithms abused bugs in their simulations -- essentially glitches in the Matrix that gave them superpowers."

An anonymous reader quotes a report from Ars Technica: A local city council member is beginning to float the idea of taxing ridehailing companies like Uber and Lyft as a possible way to raise millions of dollars and help pay for local public transportation and infrastructure improvements. If the effort is successful, Oakland could become the first city in California -- Uber and Lyft's home state -- to impose such a tax. However, it's not clear whether Oakland or any other city in the Golden State has the authority to do so under current state rules. Councilwoman Rebecca Kaplan told the East Bay Express that she wants the city council to put forward a ballot measure that would tax such rides. A similar proposal in nearby San Francisco, projecting a fee of $0.20 to $1 per ride, would allow the city to collect an estimated $12.5 to $62.5 million annually. However, an October 2017 city analysis noted that San Francisco "cannot initiate locally without state authorizing legislation" and that the fee "may disproportionately impact lower-income households."
