Many people believe that any and all opposition to the Covid vaccine comes from "far-right" Republican conspiracy theorists in the flyover states. I guess the Swiss government will now be branded with those labels as their Federal Office of Public Health is now recommending that a Covid vaccination is not needed, even for people at especially high risk. They list pregnant women and people with compromised immune systems as an exception. They further state that those who wish to receive a Covid vaccine must pay for it out of their own pockets.

In principle, no COVID-19 vaccination is recommended for spring/summer 2023. Nearly everyone in Switzerland has been vaccinated and/or contracted and recovered from COVID-19. Their immune system has therefore been exposed to the coronavirus. In spring/summer 2023, the virus will likely circulate less. The current virus variants also cause rather mild illness. For autumn 2023, the vaccination recommendation will be evaluated again and adjusted accordingly.

The reports suggest ransomware may have been involved:

Gaming hardware manufacturer MSI confirmed today that it was the victim of a cyberattack. In a brief statement on its website, the company said that the attack hit "part of its information systems," which have since returned to regular operations.

The company advises its customers only to get BIOS and firmware updates from the MSI website and no other sources. It's light on details, saying that after "detecting network anomalies," MSI implemented "defense mechanisms and carried out recovery measures," and then informed the the government and law enforcement.

[...] The post doesn't mention if customer data was stolen or affected. Tom's Hardware reached out to MSI but did not hear back in time for publication. In addition, emails to official spokesperson addresses listed on the company's website bounced.

What once appeared as a fossil of the primitive animal Dickinsonia turned out to be nothing more than a decaying beehive:

In 2020, amid the first pandemic lockdowns, a scientific conference scheduled to take place in India never happened.

But a group of geologists who were already on site decided to make the most of their time and visited the Bhimbetka Rock Shelters, a series of caves with ancient cave art near Bhopal, India. There, they spotted the fossil of Dickinsonia, a flat, elongated and primitive animal from before complex animals evolved. It marked the first-ever discovery of Dickinsonia in India.

The animal lived 550 million years ago, and the find seemed to settle once and for all the surprisingly controversial age of the rocks making up much of the Indian subcontinent. The find attracted the attention of The New York Times, The Weather Channel and the scientific journal Nature as well as many Indian newspapers.

Only, it turns out, the "fossil" was a case of mistaken identity. The true culprit? Bees.

University of Florida researchers traveled to the site last year and discovered the object had seemingly decayed significantly – quite unusual for a fossil. What's more, giant bee's nests populate the site, and the mark spotted by the scientists in 2020 closely resembled the remains of these large hives.

[...] Gregory Retallack, professor emeritus at the University of Oregon and lead author of the original paper, says he and his co-authors agree with Meert's findings that the object is really just a beehive. They are submitting a comment in support of the new paper to the journal.

This kind of self-correction is a bedrock principle of the scientific method. But the reality is that admitting errors is hard for scientists to do, and it doesn't happen often.

[...] Correcting the fossil record puts the age of the rocks back into contention. Because the rock formation doesn't have any fossils from a known time period, dating it can be difficult.

Intel Foundry Services partners with Arm to manufacture next-generation mobile chips:

Intel Corp. said today its Intel Foundry Services business unit is partnering with the British chip design firm Arm Ltd. to enable semiconductor designers to build low-power systems-on-chip on its cutting-edge manufacturing process.

The companies will initially focus on mobile SoC designs before expanding the deal to cover chips for automotive, internet of things, data center, aerospace and government applications. Under the agreement, customers that use Arm's designs as the basis of their chips will be able to use Intel's 18A process technology to manufacture their products.

The deal is said to be a big boon for customers, since Intel 18A is a more advanced process with capacity in both the U.S. and Europe. It will allow customers to design chips using electronic design automation software from third-party suppliers. EDA software is used by semiconductor engineers to create processor blueprints. The result will be more powerful processors with greater energy efficiency, Intel said.

Under the initiative, IFS and Arm will work together on design technology co-optimization, wherein chip design and process manufacturing are optimized to improve the power, performance and cost of Arm-based cores using the Intel 18A technology. Intel 18A is said to leverage two new technologies, including PowerVia for optimal power delivery and RibbonFET "gate all around" transistor architecture, which ensures optimal performance and power.

As part of this cooperation, IFS and Arm plan to develop a mobile reference design to demonstrate the technology to customers.

The deal is another key milestone for IFS, following its partnership with the Taiwanese semiconductor firm MediaTek Inc. that was announced last July. Intel set up the foundry business in 2021 to manufacture chips for other companies based on their own custom designs.

Bad news: copyright industry attacks on the Internet's plumbing are increasing – and succeeding:

Back in October 2021, Walled Culture wrote about a ruling from a US judge. It concerned an attempt to make the content delivery network (CDN) Cloudflare, which is simply part of the Internet's plumbing, responsible for what flows through its connections. The judge rightly decided: "a reasonable jury could not – at least on this record – conclude that Cloudflare materially contributes to the underlying copyright infringement".

A similar case in Germany was brought by Sony Music against the free, recursive, anycast DNS platform Quad9. Like CDNs, DNS platforms are crucial services that ensure that the Internet can function smoothly; they are not involved with any of the sites that may be accessed as a result of their services. In particular, they have no knowledge of whether copyright material on those sites is authorised or not. Unfortunately, two regional courts in Germany don't seem to understand that point, and have issued judgments against Quad9. Its FAQ on one of the cases explains why this is a dreadful result for the entire Internet:

The court argues with the German law principle of "interferer liability" the so-called "Stoererhaftung", which allows holding uninvolved third parties liable for an infringement if they have in some way adequately and causally contributed to the infringement of a protected legal interest. If DNS resolvers can be held liable as interferers, this would set a dangerous precedent for all services used in retrieving web pages. Providers of browsers, operating systems or antivirus software could be held liable as interferers on the same grounds if they do not prevent the accessibility of copyright-infringing websites.

Now an Italian court has confirmed a previous ruling that Cloudflare must block certain online sites accused of making available unauthorised copies of material. That's unfortunate, since taken with the German court rulings it is likely to encourage the copyright industry to widen its attack on the Internet's plumbing, regardless of the wider harm this is likely to cause.

https://arstechnica.com/information-technology/2023/03/3cx-knew-its-app-was-flagged-as-malicious-but-took-no-action-for-7-days/

The support team for 3CX, the VoIP/PBX software provider with more than 600,000 customers and 12 million daily users, was aware its desktop app was being flagged as malware but decided to take no action for a week when it learned it was on the receiving end of a massive supply chain attack, a thread on the company's community forum shows.

"Is anyone else seeing this issue with other A/V vendors?" one company customer asked on March 22, in a post titled "Threat alerts from SentinelOne for desktop update initiated from desktop client." The customer was referring to an endpoint malware detection product from security firm SentinelOne. Included in the post were some of SentinelOne's suspicions: the detection of shellcode, code injection to other process memory space, and other trademarks of software exploitation.

This once secretive scientific field is embracing openness in a big way:

The words "nuclear physics" tend to conjure images of heavily guarded laboratories or trench-coated spies whispering to each other on park benches and exchanging briefcases full of file folders stamped "Classified: Top Secret." But despite this reputation for secrecy, today's nuclear scientists embrace openness. And it's paying off.

[...] Many nuclear science organizations have released open source software in recent years, which is a big change from business as usual in the field. Though CERN, which focuses on fundamental particle physics rather than energy generation, is the birthplace of the web and has long embraced open source, other institutions have historically been less open. "There's a history of secrecy in the field. Most fusion and fission software used to be proprietary," says Paul Romano, the project lead for OpenMC and a computational scientist working in nuclear fusion at Argonne National Laboratory. "But as open source has exploded over the past decade, it plays an increasingly important role in research, both in the public and private sectors."

Despite open source's many benefits, it took time for the nuclear science field to adopt the open source ethos. Using open source tools was one thing—Python's vast ecosystem of mathematical and scientific computing tools is widely used for data analysis in the field—but releasing open source code was quite another.

[...] Many of these projects that started with nuclear science in mind are applicable to just about any field that benefits from using supercomputers. MFEM, for example, is also used in LLNL's cardiac simulation toolkit Cardioid, its crystal plasticity application ExaConstit, and its thermomechanical simulation code Serac. It is also heavily used by the broader scientific community, including industry and academia, in applications such as MRI research at Harvard Medical School, and quantum computing hardware simulation at Amazon. MOOSE is widely used outside of the nuclear field, with applications in areas such as groundwater modeling and other geoscience use cases. During the early days of the Covid-19 pandemic, researchers at LLNL used Merlin to anticipate outbreaks and Maestro for antibody modeling.

Open source also paves the way for anyone, regardless of their scientific background, to pitch in and help push science forward. Many of these projects can benefit from experienced software engineers, as software engineering isn't always a strength for scientific researchers. "The scientific community is trying to learn best software development practices, but there's a lot to learn from professional developers," says MIT's Peterson. "There are lots of opportunities for experienced developers to help build CI/CD pipelines, write unit tests, and generally help create higher-quality codebases."

Contributing to a project's upstream dependencies is another way to help out, LLNL's Peterson says. Merlin, for example, relies heavily on the Python-based distributed task queue Celery. And, like practically all open source projects, these need help with documentation and bug reports. "We can never get enough documentation, and not all of it needs to be written by specialists," Gaston says.

Opening repositories to specialists and non-specialists alike for collaboration is a far cry from the cloak-and-dagger image that the nuclear physics field cultivated over the decades. But it's a big part of what pushes science forward as creators gain valuable contributions from outside their own organizations. "We have hundreds of contributors at this point," says Permann, the manager of the MOOSE project. "It's not just the National Labs and universities either. Private companies are a little more cautious about what they contribute to open source, but they help out as well and there's a mutual benefit."

It also encourages the teams to write better code in the first place. "We treat every pull request like it's a submission to an academic journal," Kolev says. "When you know your code is going to be scrutinized by other people, it sets a higher bar."

Though secrecy still has its place, it takes openness to keep moving forward.

Heat batteries could help cut emissions by providing new routes to use solar and wind power:

A handful of startups think bricks that hold heat could be the key to bringing renewable energy to some of the world's biggest polluters.

Industries that make products ranging from steel to baby food require a lot of heat—most of which is currently generated by burning fossil fuels like natural gas. Heavy industry makes up about a quarter of worldwide emissions, and alternative power sources that produce fewer greenhouse gases (like wind and solar) can't consistently generate the heat that factories need to manufacture their wares.

Enter heat batteries. A growing number of companies are working to deploy systems that can capture heat generated by clean electricity and store it for later in stacks of bricks. Many of these systems use simple designs and commercially available materials, and they could be built quickly, anywhere they're needed. One demonstration in California started up earlier this year, and other test systems are following close behind. They're still in early stages, but heat storage systems have the potential to help wean industries off fossil fuels.

One key to heat batteries' potential success is their simplicity. "If you want to make it to giant scale, everybody ought to agree that it's boring and reliable," says John O'Donnell, CEO of California-based heat storage startup Rondo Energy

Many industrial processes run 24 hours a day, so they'll need constant heating. By carefully controlling the heat transfer, Rondo's system can charge quickly, taking advantage of short periods when electricity is cheap because renewable sources are available. The startup's heat batteries will probably require about four hours of charging to be able to provide heat constantly, day and night.

[...] In Rondo's system, electricity travels through a heating element, where it's transformed into heat. It's the same mechanism that a toaster uses, O'Donnell says—just a lot bigger and hotter. The heat then radiates through the stack of bricks, warming them up to temperatures that can reach over 1,500 °C (2,700 °F).

The insulated steel container housing the bricks can keep them hot for hours or even days. When it's time to use the trapped heat, fans blow air through the bricks. The air can reach temperatures of up to 1,000 °C (1,800 °F) as it travels through the gaps.

How the final heat then is used will depend on the commercial process, O'Donnell says, though many facilities will probably use it to turn water into high-pressure steam.

[...] Rondo isn't alone in its quest to deploy heat batteries in industry. Antora Energy, based in California, is also building heat storage systems, using carbon. "It's super simple—it's literally just solid blocks," says cofounder and COO Justin Briggs.

Instead of using a separate heating element (like Rondo's "toaster coil") to turn electricity into heat, Antora's system will use carbon blocks as a resistive heater, so they'll both generate and store heat. This could cut down on costs and complexity, Briggs explains. But the choice will also mean the system needs to be carefully enclosed, since graphite and other forms of carbon can degrade at high temperatures in the air.

[...] Even using commercially available materials, it'll take a while for heat storage to prove its role to manufacturers and make a meaningful dent in industrial emissions. But the technology could be one building block of a new, climate-friendly industrial sector. "We have all the tools we need to transform to a zero-carbon economy," O'Donnell says. Now it's time to build them.

Thanks to large language models, a single scammer can run hundreds or thousands of cons in parallel, night and day, in every language under the sun:

Here's an experiment being run by undergraduate computer science students everywhere: Ask ChatGPT to generate phishing emails, and test whether these are better at persuading victims to respond or click on the link than the usual spam. It's an interesting experiment, and the results are likely to vary wildly based on the details of the experiment.

But while it's an easy experiment to run, it misses the real risk of large language models (LLMs) writing scam emails. Today's human-run scams aren't limited by the number of people who respond to the initial email contact. They're limited by the labor-intensive process of persuading those people to send the scammer money. LLMs are about to change that.

[...] Long-running financial scams are now known as pig butchering, growing the potential mark up until their ultimate and sudden demise. Such scams, which require gaining trust and infiltrating a target's personal finances, take weeks or even months of personal time and repeated interactions. It's a high stakes and low probability game that the scammer is playing.

Here is where LLMs will make a difference. Much has been written about the unreliability of OpenAI's GPT models and those like them: They "hallucinate" frequently, making up things about the world and confidently spouting nonsense. For entertainment, this is fine, but for most practical uses it's a problem. It is, however, not a bug but a feature when it comes to scams: LLMs' ability to confidently roll with the punches, no matter what a user throws at them, will prove useful to scammers as they navigate hostile, bemused, and gullible scam targets by the billions. AI chatbot scams can ensnare more people, because the pool of victims who will fall for a more subtle and flexible scammer—one that has been trained on everything ever written online—is much larger than the pool of those who believe the king of Nigeria wants to give them a billion dollars.

[...] A single scammer, from their laptop anywhere in the world, can now run hundreds or thousands of scams in parallel, night and day, with marks all over the world, in every language under the sun. The AI chatbots will never sleep and will always be adapting along their path to their objectives. And new mechanisms, from ChatGPT plugins to LangChain, will enable composition of AI with thousands of API-based cloud services and open source tools, allowing LLMs to interact with the internet as humans do. The impersonations in such scams are no longer just princes offering their country's riches. They are forlorn strangers looking for romance, hot new cryptocurrencies that are soon to skyrocket in value, and seemingly-sound new financial websites offering amazing returns on deposits. And people are already falling in love with LLMs.

[...] Companies like OpenAI attempt to prevent their models from doing bad things. But with the release of each new LLM, social media sites buzz with new AI jailbreaks that evade the new restrictions put in place by the AI's designers. ChatGPT, and then Bing Chat, and then GPT-4 were all jailbroken within minutes of their release, and in dozens of different ways. Most protections against bad uses and harmful output are only skin-deep, easily evaded by determined users. Once a jailbreak is discovered, it usually can be generalized, and the community of users pulls the LLM open through the chinks in its armor. And the technology is advancing too fast for anyone to fully understand how they work, even the designers.

The stream could keep the galaxy supplied with star-forming fuel for a billion years:

A long, cold stream of gas is feeding a very distant galaxy like a vast bendy straw. The finding suggests a new way for galaxies to grow in the early universe, researchers report in the March 31 Science.

Computer simulations predicted that streams of gas should connect galaxies to the cosmic web (SN: 3/6/23). But astronomers expected that gas to be warm, making it unsuitable for star-forming fuel and galaxy growth.

So astronomer Bjorn Emonts and his colleagues were surprised to see a stream of cold, star-forming gas leading into the Anthill Galaxy, a massive galaxy whose light takes 12 billion years to reach Earth.

[...] "People didn't think that these streams could get so cold," says Emonts, of the National Radio Astronomy Observatory in Charlottesville, Va.

But there, in the data, a frigid stream stretched at least 325,000 light-years away from the galaxy. The stream carries the mass of 70 billion suns and deposits the equivalent of about 450 suns in cold gas onto the galaxy every year, the team calculated. That's enough to double the galaxy's mass within a billion years.

[...] If other galaxies are fed by similar structures, it could mean that early galaxies grew mostly by drinking directly from the cosmic streams, rather than by the leading hypothesis — violent galaxy mergers (SN: 6/28/19).

New editor is integrated with Python lessons:

When we think about Raspberry Pi, we normally picture single-board computers, but the Raspberry Pi Foundation was started to help kids learn about computers and it wants to help whether or not you own its hardware. The non-profit arm of Raspberry Pi this week released its new, browser-based code editor that's designed for young people (or any people) who are learning.

The Raspberry Pi Code Editor, which is considered to be in beta, is available to everyone for free right now at editor.raspberrypi.org. The editor is currently designed to work with Python only, but the organization says that support for other languages such as HTML, JavaScript and CSS is coming.

I tried out the Code Editor on my PC's browser and, in its current form, there's nothing particularly unique about it. However, I found the UI very user-friendly and was impressed with how it is integrated into someone online tutorials. The interface consists of three panes: a list of files in your project, a code editor and an output pane that runs the result of your code when you hit the Run button.

If you create a free account on raspberrypi.org, which I did, the system will save all of your projects in the cloud and you can reload them any time you want. You can also download all the files in a project as a .zip file.

Since the entire programming experience takes place online, there's no way (at least right now) to use Python to control local hardware on your PC or your Raspberry Pi. If you want to attach one of the best Raspberry Pi HATs or use the GPIO pins on your Pi to light up an LED light, you need a local editor like Thonny, which comes preinstalled on all Raspberry Pis and is a free download for Windows, Mac and Linux.

The Raspberry Pi Code editor isn't the only online Python editor around by any stretch of the imagination as you can also use a service such as Trinket.io, which will let you write Python code in one pane while previewing it in another. However, what's interesting about Raspberry Pi's tool is that the organization has a few Python tutorials that are designed to be used with it.

The Raspberry Pi Foundation already had a nice set of Python tutorials on its site, but it has adapted some of them to open sample code directly in the online editor. For example, when I tried the "Say hello" lesson, the first link on the page opens the working set of code in the editor in a new tab in my browser. When I revisited the page and clicked the link a few minutes later, it took me back to the same code I had edited before, because it saved the lesson as a project that was associated with my account.

"You can call it a lie by omission":

Florida health officials deleted key data and statistics from a state analysis on the safety of mRNA COVID-19 vaccines, falsely making them appear unsafe for young men, according to draft versions of the analysis obtained by the Tampa Bay Times through public records requests.

The final analysis, which was widely criticized for its poor quality and dubious conclusions, was the basis for a statewide recommendation by Surgeon General Joseph Ladapo last October that young men, ages 18 to 39, should not receive an mRNA COVID-19 vaccine. The analysis—posted on the Florida Department of Health's website with no authors listed—claimed to find "an 84% increase in the relative incidence of cardiac-related death among males 18-39 years old within 28 days following mRNA vaccination."

Ladapo, who has a history of fearmongering about COVID-19 vaccines, touted the analysis, saying in a press release at the time that "these are important findings that should be communicated to Floridians."

But according to draft versions of the analysis, the state epidemiologists who worked on the report came to entirely different conclusions.

The draft version contained data that showed that getting COVID-19 posed a far greater risk of cardiac-related deaths than that from mRNA vaccines. Specifically, the incidence of cardiac-related deaths from infection was more than 10 times higher than from the vaccine in people ages 18 to 24 and more than five times higher for people 25 to 39. This data is in line with many peer-reviewed, published studies but was omitted entirely from the final analysis announced by Ladapo.

Also omitted was a sensitivity analysis that showed that the risk of cardiac-related deaths in young men was not significant. The final version drew flak for not including a sensitivity analysis, with the core conclusion of risk in young men hinging on just 20 deaths. A sensitivity analysis is a means to essentially evaluate the robustness of a finding, and it was present in three versions of the draft analysis but not in the final one.

[...] Overall, the draft versions of the analysis written by state epidemiologists supported the use of mRNA. "The risk associated with COVID-19 infection clearly outweighs any potential risks associated with mRNA vaccination," one version states.

Matt Hitchings, an infectious disease epidemiologist and professor of biostatistics at the University of Florida, who also reviewed the drafts for the Times, told the outlet that the excluded data was akin to academic dishonesty. "You can call it a lie by omission," he said.

What Flight 50 Means for the Ingenuity Mars Helicopter:

JPL's Ingenuity helicopter is preparing for the 50th flight of its 5-flight mission to Mars. Flight 49, which took place last weekend, was its fastest and highest yet—the little helicopter flew 282 meters at an altitude of 16 meters, reaching a top speed of 6.50 meters per second. Not a bad performance for a tech demo that was supposed to be terminated two years ago.

From here, things are only going to get more difficult for Ingenuity. As the Perseverance rover continues its climb up Jezero crater's ancient river delta, Ingenuity is trying its best to scout ahead. But, the winding hills and valleys make it difficult for the helicopter to communicate with the rover, and through the rover, to its team back on Earth. And there isn't a lot of time or room to spare, because Ingenuity isn't allowed to fly too close to Perseverance, meaning that if the rover ever catches up to the helicopter, the helicopter may have to be left behind for the rover's own safety. This high-stakes race between the helicopter scout and the science rover will continue for kilometers.

For the Ingenuity team, this new mode of operation was both a challenge and an opportunity. This was nothing new for folks who have managed to keep this 30-day technology demo alive and healthy and productive for years, all from a couple hundred million kilometers away. IEEE Spectrum spoke with Ingenuity Team Lead Teddy Tzanetos at JPL last week about whether flying on Mars is ever routine, how they upgraded Ingenuity for its extended mission, and what the helicopter's success means for the future of airborne exploration and science on Mars.

The core of the challenge here is that the paradigm has changed. When you look at the first year of Ingenuity's extended operations, we were still in the Three Forks area, where the ground was flat. We could get line of sight from the helicopter to the rover from hundreds and hundreds of meters away. Our longest link that we established was 1.2 kilometers—a massive distance.

And then we started to realize that the rover was going to enter the river delta in like six months. It's going to start climbing up through dozens and dozens of meters of elevation change and passing through ravines, and that's going to start presenting a telecom issue for us. We knew that it couldn't be business as usual anymore—if we still wanted to keep this helicopter mission going, not only did we need to change the way we were operating, but we also had to change the helicopter itself.

Videos obtained by WIRED from public transit vehicles reveal self-driving cars causing delays and potential danger to buses, trains, and passengers:

[...] The 54 [Felton line], brought to a halt by an autonomous vehicle belonging to Alphabet's Waymo, isn't the only bus that's run into trouble with San Francisco's growing crowd of driverless vehicles. Bus and train surveillance videos obtained by WIRED through public records requests show a litany of incidents since September in which anxiety and confusion stirred up by driverless cars has spilled onto the streets of the US city that has become the epicenter for testing them.

As the incidents stack up, the companies behind the autonomous vehicles, such as Waymo and General Motors' Cruise, want to add more robotaxis to San Francisco's streets, cover more territory, and run at all hours. Waymo and Cruise say they learn from every incident. Each has logged over 1 million driverless miles and say their cars are safe enough to keep powering forward. But expansions are subject to approval from California state regulators, which have been pressed by San Francisco officials for years to restrict autonomous vehicles until issues subside.

Driverless cars have completed thousands of journeys in San Francisco—taking people to work, to school, and to and from dates. They have also proven to be a glitchy nuisancesnarling traffic and creeping into hazardous terrain such as construction zones and downedpower lines. Autonomous cars in San Francisco made 92 unplanned stops between May and December 2022—88 percent of them on streets with transit service, according to city transportation authorities, who collected the data from social media reports, 911 calls, and other sources, because companies aren't required to report all the breakdowns.

The records obtained by WIRED are more focused. They follow a previously unreported directive to staff of the San Francisco Municipal Transportation Agency handed down last October to improve record keeping of incidents involving autonomous vehicles. Muni, as the agency is known, standardized the term "driverless car" when staff report "near-misses, collisions or other incidents resulting in transit delay," according to the directive. Agency logs show 12 "driverless" reports from September 2022 through March 8, 2023, though Muni video was provided for only eight of these cases. Overall, the incidents resulted in at least 83 minutes of direct delays for Muni riders, records show.

That data likely doesn't reflect the true scale of the problem. Muni staff don't follow every directive to the letter, and a single delay can slow other lines, worsening the blow. Buses and trains cannot weave around blockages as easily as pedestrians, other motorists, and cyclists, saddling transit-dependent travelers with some of the biggest headaches caused by errant driverless cars, according to transit advocates.

That left the Muni driver in a bind. "I can't move the bus," the driver said to one of two riders on board. "The car is automatic driving." The driver radioed managers and doffed their cap: "Whoosh ... Half hour, one hour. I don't know. Nothing to do." Thirty-eight stops and about five miles remained ahead for the 54. The driver, looking out at the Waymo, expressed disappointment: "This one not smart yet. Not smart. Not good."

Waymo's Karp says one of the company's roadside assistance crews arrived within 11 minutes of being dispatched to drive the SUV, clearing the blockage about 15 minutes after it began. Karp declined to elaborate on why the remote responder's guidance failed but said engineers have since introduced an unspecified change that allows addressing "these rare situations faster and with more flexibility."

The Transport Workers Union, which represents Muni train and bus drivers, deferred comment for this story to Muni. The agency declined to make drivers described in this story available for comment. But Tumlin, the Muni director, says San Francisco's transit workers are frustrated. "When you encounter a vehicle with no human on board, it is dispiriting and disempowering," he says. "There's no one there to communicate with at all."

The 3D5000 has come out of the oven:

Loongson, a Chinese fabless chipmaker, has launched the new 3D5000 processor for data centers and cloud computing. MyDrivers (opens in new tab) reported that Loongson claims its 32-core domestic chips deliver 4X higher performance than rival Arm processors.

The 3D5000 still leverages LoongArch, Loongson's homemade instruction set architecture (ISA) from 2020. The chipmaker was previously a firm believer in MIPS. However, Loongson eventually built LoongArch from the ground up with the sole objective of not relying on foreign technology to develop its processors. LoongArch is a RISC (reduced instruction set computer) ISA, similar to MIPS or RISC-V.

The 3D5000 arrives with 32 LA464 cores running at 2 GHz. The 32-core processor has 64MB of L3 cache, supports eight-channel DDR4-3200 ECC memory, and up to five HyperTransport (HT) 3.0 interfaces. It also supports dynamic frequency and voltage adjustments. Officially, the 3D5000 has a 300W TDP; however, Loongson stated that the conventional power consumption is around 150W. That's roughly 5W per core.

The 3D5000 flaunts a chiplet design since Loongson has glued together two 16-core 3C5000 processors. Loongson developed the 3C5000 server part to compete with AMD's Zen and Zen+ architectures. The latest 3D5000, which measures 75.4 x 58.5 x 7.1mm, slides into a custom LGA4129 socket.

The processor supports 2P and 4P configurations; therefore, Loongson has launched the 7A2000 bridge chip to manage the communication between the processors and other components. As per the chip designer, the 7A2000 is up to 400% faster than the previous generation. Furthermore, with the help of the 7A2000, there's a possibility to scale up to 128 cores per motherboard.

According to Loongson's provided numbers, the 3D5000 scores over 425 points in SPEC CPU 2006, a depreciated benchmark replaced with the newer SPEC CPU 2017 version. The 3D5000 also delivers over 1 TFLOPs of FP64 performance, up to 4X higher than regular Arm cores. Meanwhile, the processor's stream performance with eight channels of DDR4-3200 memory crosses the 50GB mark.

While performance isn't the 3D5000's strong suit, security is. The 32-core processor allegedly has a custom-made mechanism to defend against vulnerabilities such as Meltdown or Spectre. The chip also has its Trusted Platform Module (TPM), so it doesn't rely on an external solution. In addition, according to MyDrivers' report, the 3D5000 also supports a secret national algorithm with an embedded security module that seemingly delivers excellent encryption and decryption efficiency higher than 5 Gbps.
