An anonymous reader shares a report: Today's announcement from SiFive comes in two parts; this part is significant as it recognizes that Intel will be enabling SiFive's IP portfolio on its 7nm manufacturing process for upcoming foundry customers. We are expecting Intel to offer a wide variety of its own IP, such as some of the x86 cores, memory controllers, PCIe controllers, and accelerators, however the depth of its third party IP support has not been fully established at this point. SiFive's IP is the first (we believe) official confirmation of specific IP that will be supported. Announced earlier this year by Pat Gelsinger, Intel Foundry Services (or IFS) is one prong of Intel's strategy to realign itself with the current and future semiconductor market. Despite having attempted to become a foundry player in the past, whereby they build chips under contract for their customers, it hasn't really worked out that well -- however IFS is a new reinvigoration of that idea, this time with more emphasis on getting it right and expanding the scope.

Last Thursday, a Canadian company backed by Jeff Bezos, called General Fusion, announced it's building a nuclear fusion facility in the UK. Insider reports: General Fusion and the UK Atomic Energy Authority (UKAEA) announced the project together, which will see General Fusion build a fusion demonstration plant in the village of Culham, near Oxford. The facility will be a proof-of-concept, allowing General Fusion to demonstrate its Magnetized Target Fusion (MTF) technology before going on to build its first commercial facility. According to General Fusion, construction will begin in 2022, and it is expected to be about three years before the plant is able to open.

"This new plant by General Fusion is a huge boost for our plans to develop a fusion industry in the UK, and I'm thrilled that Culham will be home to such a cutting-edge and potentially transformative project," the UK science minister, Amanda Solloway, said in a statement. The BBC reports Bezos has been an investor in General Fusion for over a decade, and the company raised $100 million in its latest funding round.

Bloomberg's Mark Gurman, Apple analyst Ming-Chi Kuo, and leaker Jon Prosser say Apple is working on a completely new, high-end version of the MacBook Air. MacRumors reports: The high-end MacBook Air will feature two USB-C ports and a more powerful Apple silicon chip, according to Gurman. The chip will apparently be a direct successor to Apple's M1 chip, featuring the same number of computing cores, but it will run faster. It is also expected to see an increase in graphics cores from seven or eight to nine or 10. This high-end MacBook Air would sit above the current MacBook Air models with the M1 chip, but below the MacBook Pro. Prosser recently unveiled renders that purport to depict the next-generation MacBook Air based on leaked images.

Prosser says that the MacBook Air will be available in a range of color options, much like the 24-inch iMac, and will feature larger function keys, a smaller trackpad, and redesigned feet on the underside of the machine. The biggest change in terms of design from the current MacBook Air seems to be the loss of its iconic tapered design. Instead, the MacBook Air will become considerably thinner as a whole, Prosser explained. Other features rumored to be coming to next-generation MacBook Air models include a mini-LED display and a MagSafe charging port. Gurman believes that the high-end MacBook Air could launch in the second half of this year at the earliest or in 2022, a timeframe that has been echoed by Prosser.

Boston Dynamics has been purchased by Hyundai in a deal valued at $1.1 billion. According to Motherboard, the deal "sees Hyundai assume an 80 percent controlling stake in the robot company. Softbank will retain a 20 percent stake." From the report: It is hard to tell what Hyundai wants out of Boston Dynamics from the press release, which is laden with technobabble. Robots in car manufacturing are nothing new, but Hyundai says the acquisition is "another major step toward its strategic transformation into a Smart Mobility Solution Provider" such as "autonomous driving, artificial intelligence (AI), Urban Air Mobility (UAM), smart factories and robots," which seems to speak to the company's ambitions beyond car manufacturing. Hyundai says it hopes to "develop advanced technologies that enhance people's lives and promote safety, thereby realizing the progress for humanity."

Apparently, the "progress of humanity" means a lot less of it. To celebrate the purchase, Hyundai released a bizarre hype video featuring a seeing-eye robot dog, a nurse robot dog with a tablet mounted on its head that allows the patient to nod at a doctor who is somewhere else, and a teen dancing with a robot in the street. In other words, Hyundai envisions a lonely future in which social cohesion between humans has broken down and robots are our only friends. That's all bad enough, but why anyone would want a seeing eye robot dog instead of a real dog is beyond comprehension.

According to ComputerBase, graphics card prices have begun to drop as much as 50% in Europe. From a report: Availability has also improved significantly, with sales of most GPU models from both AMD and Nvidia doubling month-over-month. This report comes on the heels of ASRock, a GPU maker, noting that GPU pricing is easing as demand from Chinese cryptocurrency miners wanes. More budget-oriented cards like the Nvidia GeForce RTX 3060 and AMD Radeon RX 6700 XT are seeing the most positive results, with a near 50% drop in price compared to last month. For flagship cards like the RTX 3080 and RX 6800 XT, however, prices haven't moved as much. They have dipped a respectable 10-15% which is still a very positive change considering the shortage issues plaguing the technology industry. In the United States, GPU pricing is slowly catching up to Europe, but it's still going down nonetheless.

Long-time Slashdot reader cusco shares an interesting report from IEEE Spectrum: In 2017, we first wrote about the Chinese startup Unitree Robotics, which had the goal of "making legged robots as popular and affordable as smartphones and drones." Relative to the cost of other quadrupedal robots (like Boston Dynamics' $74,000 Spot), Unitree's quadrupeds are very affordable, with their A1 costing under $10,000 when it became available in 2020. This hasn't quite reached the point of consumer electronics that Unitree is aiming for, but they've just gotten a lot closer: now available is the Unitree Go1, a totally decent looking small size quadruped that can be yours for an astonishingly low $2700.

Speedy, good looking gait, robust, and a nifty combination of autonomous human-following and obstacle avoidance... There are three versions of the Go1: the $2700 base model Go1 Air, the $3500 Go1, and the $8500 Go1 Edu... The top of the line Edu model offers higher end computing, 2kg more payload (up to 5kg), as well as foot-force sensors, lidar, and a hardware extension interface and API access... Battery life is a big question — the video seems to suggest that the Go1 is capable of a three-kilometer, 20-minute jog, and then some grocery shopping and a picnic, all while doing obstacle avoidance and person following and with an occasional payload.
Unitree later provided the reporter more detailed specs:

• The battery life of the robot while jogging is about 1 hour
• It weighs 12kg
• The Super Sensory System includes five wide-angle stereo depth cameras, hypersonic distance sensors, and an integrated processing system
• It's running at 16 core CPU and a 1.5 tflop GPU

Slashdot reader quonset writes: With the heat wave gripping Texas, and in an effort to prevent another collapse of the power grid as happened in February during cold weather, Texas is, for the third day in a row, asking residents to conserve electricity. Some people in the Houston area have come home to find the temperatures in their homes are still warm (in the high 70s to low 80s) despite their air conditioning running all day!
A local Texas reporter tells the tale: The family's smart thermostat was installed a few years ago as part of a new home security package. Many smart thermostats can be enrolled in a program called "Smart Savers Texas." It's operated by a company called EnergyHub. The agreement states that in exchange for an entry into sweepstakes, electric customers allow them to control their thermostats during periods of high energy demand. EnergyHub's list of its clients include TXU Energy, CenterPoint and ERCOT.
They spoke to one Texas resident who obviously wasn't even aware of what he'd agreed to when the smart thermostat was installed. As soon as he found out, he immediately unenrolled from the program, complaining "If somebody else can manipulate this, I'm not for it."

Check out this video footage of the sleek Mayflower 400 slicing through the water, hoping to retrace the historic 1620 journey of the famous ship which carried pilgrims to America. Unfortunately, unlike the real Mayflower, this robotic 21st-century doppelganger "had to turn back Friday to fix a mechanical problem," reports the Associated Press: Nonprofit marine research organization ProMare, which worked with IBM to build the autonomous ship, said it made the decision to return to base "to investigate and fix a minor mechanical issue" but hopes to be back on the trans-Atlantic journey as soon as possible.

With no humans on board the ship, there's no one to make repairs while it's at sea.

Piloted by artificial intelligence technology, the 50-foot (15-meter) Mayflower Autonomous Ship began its trip early Tuesday, departing from Plymouth, England, and spending some time off the Isles of Scilly before it headed for deeper waters.

It was supposed to take up to three weeks to reach Provincetown on Cape Cod before making its way to Plymouth, Massachusetts. If successful, it would be the largest autonomous vessel to cross the Atlantic.

A month ago, Amazon-first gadget brands Aukey and Mpow suddenly and mysteriously disappeared from the giant online retailer's storefront, with almost all their electronics vanishing from Amazon's shelves. Today, popular battery and charger brand RavPower has completely disappeared as well. From a report: All of the company's product listings have disappeared, leaving blank white spaces in RavPower's Amazon storefront. Searches for "RavPower" don't bring up any listings for products made by the company. Existing links to RavPower products either point to Amazon's "Sorry, we couldn't find that page" cute 404 dogs, or listings that read "Currently unavailable." By and large, this is exactly what happened to Aukey, Mpow, and other lesser-known electronics retailers last month -- except here, whoever did this has been a bit more thorough.

CNET News : We'll let Razer have its 5 minutes of E3 glory for the "world's fastest 14-inch gaming laptop," the Razer Blade 14. Razer's simply the first to announce one this size with an AMD Ryzen 9 5900HX -- also Razer's first AMD CPU in the Blade line -- and an Nvidia GeForce RTX 3080 crammed inside. But a svelte, small, no-compromise (well, minimal compromise) gaming laptop from Razer is always welcome. Along with the laptop, the company launched a new wall charger, based on Gallium Nitride rather than silicon, its USB-C 130W GaN Charger. No weird names for that one. The last 14-inch Razer Blade debuted in 2017, and it makes sense that Razer would revive it for the 14-inch laptop renaissance that began around 2020. The 2021 Blade 14, as you'd expect, looks like a somewhat shrunken version of the 15-inch, though it's roughly the same thickness as the 15-inch at 16.8mm.

There will be three models of the Blade 14 at launch. All use the Ryzen 9 5900HX, with the same 1TB SSD, 16GB RAM and 720p webcam, as well as Razer's THX Spatial Audio, HDMI 2.1 and other ports and so on. The entry-level $1,800 model incorporates a 144Hz 1080p screen and an RTX 3060 GPU; for $2,200 you upgrade to an RTX 3070 with a 165Hz 1440p display, and $2,800 bumps that to an RTX 3080. The SSD is upgradable but the RAM is soldered to the motherboard, which is kind of a bummer. The screens support FreeSync Premium adaptive refresh through G-Sync compability mode. Razer rates the battery life at up to 12 hours, though it's likely in the ballpark of 10 hours based on what we've seen elsewhere. As you'd expect, the RTX 3080 isn't being pushed to the max in this system; the GPU power draw can range anywhere from 80 to 150 watts, and Razer takes the middle road at 100 watts. In comparison, the hefty 15-inch Asus ROG Strix Scar we're testing pulls down 130 watts.

Slashdot reader Charlotte Web writes: The "Group of Seven" (or G7) nations are some of the world's largest economies — the U.S. and Canada, the U.K., France, Germany, and Italy, and Japan. On Sunday they pledged $2 billion to help developing countries pivot away from fossil fuels and pledged an "overwhelmingly decarbonized" electricity sector by 2030. The New York Times calls these "major steps in what leaders hope will be a global transition to wind, solar and other energy that does not produce planet-warming carbon dioxide emissions."

Politico's Ryan Heath argues "The language on a 'green revolution' is quite strong — there's plenty of detail missing, but it gives climate campaigners a lot to hit leaders with if they fail to deliver. And it's a big deal for the G-7 to agree to 'to conserve or protect at least 30 percent of our land and oceans by 2030.'"
Other reports from Politico's writers:

• "Boris Johnson admitted that the world's richest economies had not managed to secure a widely advertised 1 billion vaccine doses to send to developing countries. The final communique says the group will deliver 870 million doses over the next year."

• "The G-7 nations called for a 'timely, transparent, expert-led, and science-based WHO-convened' investigation into the origins of Covid-19, including in China. WHO's first crack at an investigation — released in March — called a lab leak 'extremely unlikely,' but China didn't grant access to key documents and Secretary of State Antony Blinken called that investigation 'highly deficient' this morning. The U.S. government remains split between two origin theories."

Bloomberg Businessweek reports on "renewed interest in cables that can power consumers in one country with electricity generated hundreds, even thousands, of miles away in another" and possibly even transcontinental, submarine electricity superhighways: Coal, gas and even nuclear plants can be built close to the markets they serve, but the utility-scale solar and wind farms many believe essential to meet climate targets often can't. They need to be put wherever the wind and sun are strongest, which can be hundreds or thousands of miles from urban centers. Long cables can also connect peak afternoon solar power in one time zone to peak evening demand in another, reducing the price volatility caused by mismatches in supply and demand as well as the need for fossil-fueled back up capacity when the sun or wind fade. As countries phase out carbon to meet climate goals, they'll have to spend at least $14 trillion to strengthen grids by 2050, according to Bloomberg New Energy Finance. That's only a little shy of projected spending on new renewable generation capacity and it's increasingly clear that high- and ultra-high-voltage direct current lines will play a part in the transition.

The question is how international will they be...?
The article points out that in theory, Mongolia's Gobi desert "has potential to deliver 2.6 terawatts of wind and solar power — more than double the U.S.'s entire installed power generation capacity — to a group of Asian powerhouse economies that together produce well over a third of global carbon emissions..." The same goes for the U.S., where with the right infrastructure, New York could tap into sun- and wind-rich resources from the South and Midwest. An even more ambitious vision would access power from as far afield as Canada or Chile's Atacama Desert, which has the world's highest known levels of solar power potential per square meter. Jeremy Rifkin, a U.S. economist who has become the go-to figure for countries looking to remake their infrastructure for the digital and renewable future, sees potential for a single, 1.1 billion-person electricity market in the Americas that would be almost as big as China's. Rifkin has advised Germany and the EU, as well as China...

Persuading countries to rely on each other to keep the lights on is tough, but the universal, yet intermittent nature of solar and wind energy also makes it inevitable, according to Rifkin. "This isn't the geopolitics of fossil fuels," owned by some and bought by others, he says. "It is biosphere politics, based on geography. Wind and sun force sharing...."

If these supergrids don't get built, it will be because their time has both come and gone. Not only are they expensive, politically difficult, and unpopular — they have to cross a lot of backyards — their focus on mega-power installations seems outdated to some. Distributed microgeneration as close to home as your rooftop, battery storage, and transportable hydrogen all offer competing solutions to the delivery problems supergrids aim to solve.

A total of 15 potential sites are in the running to host the UK's first prototype fusion power plant. The BBC reports: Fusion is seen as a potential source of almost limitless clean energy but is currently only used in experiments. An open call for sites was made last year and nominations closed at the end of March this year. Following checks for compliance with key entry criteria the UK Atomic Energy Agency (UKAEA) has published a long list of possible locations. The sites, from north to south, with nominating body, are: Dounreay, East Airdrie, Poneil, Ardeer, Chapelcross, Moorside, Bay Fusion, Goole, West Burton, Ratcliffe on Soar, Pembroke, Severn Edge, Aberthaw, Bridgwater Bay, and Bradwell (Essex).

The UKAEA said that acceptance of the sites did not indicate that they were "preferred or desired" or that it believed they were "in all cases, possible." It stressed it was simply that the procedural entry criteria had been met and assessment had now begun. It said a shortlisting process would take place in the autumn with a final site decision likely by the end of next year. UKAEA is hoping to have such a plant operating in the early 2040s, with an initial concept design ready by 2024."

Chip floorplanning is the engineering task of designing the physical layout of a computer chip. In a paper published in the journal Nature, Google researchers applied a deep reinforcement learning approach to chip floorplanning, creating a new technique that "automatically generates chip floorplans that are superior or comparable to those produced by humans in all key metrics, including power consumption, performance and chip area." VentureBeat reports: The Google team's solution is a reinforcement learning method capable of generalizing across chips, meaning that it can learn from experience to become both better and faster at placing new chips. Training AI-driven design systems that generalize across chips is challenging because it requires learning to optimize the placement of all possible chip netlists (graphs of circuit components like memory components and standard cells including logic gates) onto all possible canvases. [...] The researchers' system aims to place a "netlist" graph of logic gates, memory, and more onto a chip canvas, such that the design optimizes power, performance, and area (PPA) while adhering to constraints on placement density and routing congestion. The graphs range in size from millions to billions of nodes grouped in thousands of clusters, and typically, evaluating the target metrics takes from hours to over a day.

Starting with an empty chip, the Google team's system places components sequentially until it completes the netlist. To guide the system in selecting which components to place first, components are sorted by descending size; placing larger components first reduces the chance there's no feasible placement for it later. Training the system required creating a dataset of 10,000 chip placements, where the input is the state associated with the given placement and the label is the reward for the placement (i.e., wirelength and congestion). The researchers built it by first picking five different chip netlists, to which an AI algorithm was applied to create 2,000 diverse placements for each netlist. The system took 48 hours to "pre-train" on an Nvidia Volta graphics card and 10 CPUs, each with 2GB of RAM. Fine-tuning initially took up to 6 hours, but applying the pre-trained system to a new netlist without fine-tuning generated placement in less than a second on a single GPU in later benchmarks. In one test, the Google researchers compared their system's recommendations with a manual baseline: the production design of a previous-generation TPU chip created by Google's TPU physical design team. Both the system and the human experts consistently generated viable placements that met timing and congestion requirements, but the AI system also outperformed or matched manual placements in area, power, and wirelength while taking far less time to meet design criteria.

Graphene can be used for ultra-high density hard disk drives (HDD), with up to a tenfold jump compared to current technologies, researchers at the Cambridge Graphene Center have shown. Phys.Org reports: The study, published in Nature Communications, was carried out in collaboration with teams at the University of Exeter, India, Switzerland, Singapore, and the US. [...] HDDs contain two major components: platters and a head. Data are written on the platters using a magnetic head, which moves rapidly above them as they spin. The space between head and platter is continually decreasing to enable higher densities. Currently, carbon-based overcoats (COCs) -- layers used to protect platters from mechanical damages and corrosion -- occupy a significant part of this spacing. The data density of HDDs has quadrupled since 1990, and the COC thickness has reduced from 12.5nm to around 3nm, which corresponds to one terabyte per square inch. Now, graphene has enabled researchers to multiply this by ten.

The Cambridge researchers have replaced commercial COCs with one to four layers of graphene, and tested friction, wear, corrosion, thermal stability, and lubricant compatibility. Beyond its unbeatable thinness, graphene fulfills all the ideal properties of an HDD overcoat in terms of corrosion protection, low friction, wear resistance, hardness, lubricant compatibility, and surface smoothness. Graphene enables two-fold reduction in friction and provides better corrosion and wear than state-of-the-art solutions. In fact, one single graphene layer reduces corrosion by 2.5 times. Cambridge scientists transferred graphene onto hard disks made of iron-platinum as the magnetic recording layer, and tested Heat-Assisted Magnetic Recording (HAMR) -- a new technology that enables an increase in storage density by heating the recording layer to high temperatures. Current COCs do not perform at these high temperatures, but graphene does. Thus, graphene, coupled with HAMR, can outperform current HDDs, providing an unprecedented data density, higher than 10 terabytes per square inch.

New submitter DaveV1.0 shares a report from CNBC: At 10 McDonald's locations in Chicago, workers aren't taking down customers' drive-thru orders for McNuggets and french fries -- a computer is, CEO Chris Kempczinski said Wednesday. Kempczinski said the restaurants using the voice-ordering technology are seeing about 85% order accuracy. Only about a fifth of orders need to be a taken by a human at those locations, he said, speaking at Alliance Bernstein's Strategic Decisions conference.

In 2019, under former CEO Steve Easterbrook, McDonald's went on a spending spree, snapping up restaurant tech. One of those acquisitions was Apprente, which uses artificial intelligence software to take drive-thru orders. Kempczinski said the technology will likely take more than one or two years to implement. "Now there's a big leap from going to 10 restaurants in Chicago to 14,000 restaurants across the U.S., with an infinite number of promo permutations, menu permutations, dialect permutations, weather — and on and on and on," he said. Another challenge has been training restaurant workers to stop themselves from jumping in to help.

An anonymous reader quotes a report from TechCrunch: With increased demand from the pandemic, Canalys reports that U.S. PC shipments were up 73% over the same period last year. That added up to a total of 34 million units sold. While Apple had a good quarter with sales up 36%, it was surpassed by HP, which sold 11 million units in total with annual growth up an astonishing 122.6%. As Canalys pointed out, the first quarter tends to be a weaker one for Apple hardware following the holiday season, but it's a big move for HP nonetheless. Other companies boasting big growth numbers include Samsung at 116% and Lenovo at 92.8%. Dell was up 29.2%, fairly modest compared with the rest of the group.

Overall though it was a stunning quarter as units flew off the shelves. Canalys Research Analyst Brian Lynch says some of this can be attributed to the increased demand from 2020 as people moved to work and school from home and needed new machines to get their work done, but regardless the growth was unrivaled historically. " Q1 2021 still rates as one of the best first quarters the industry has ever seen. Vendors have prioritized fulfilling U.S. backlogs before supply issues are addressed in other parts of the world," Lynch said in a statement. Perhaps not surprisingly, low-cost Chromebooks were the most popular item as people looking to refresh their devices, especially for education purposes, turned to the lower end of the PC market, which likely had a negative impact on higher-priced Apple products, as well contributing to its drop from the top spot. According to Canalys, Chromebook sales were up a whopping 548% with Samsung leading that growth with an astonishing 1,963% growth rate. "Asus, HP and Lenovo all reported Chromebook sales rates up over 900%," adds TechCrunch.

An anonymous reader shares a report from The Conversation: As people around the world escape poverty, you might expect their energy use to increase. But my research in Nepal, Vietnam, and Zambia found the opposite: lower levels of deprivation were linked to lower levels of energy demand. What is behind this counterintuitive finding? [...] We found that households that do have access to clean fuels, safe water, basic education and adequate food -- that is, those not in extreme poverty -- can use as little as half the energy of the national average in their country. This is important, as it goes directly against the argument that more resources and energy will be needed for people in the global south to escape extreme poverty. The biggest factor is the switch from traditional cooking fuels, like firewood or charcoal, to more efficient (and less polluting) electricity and gas.

In Zambia, Nepal, and Vietnam, modern energy resources are extremely unfairly distributed -- more so than income, general spending, or even spending on leisure. As a consequence, poorer households use more dirty energy than richer households, with ensuing health and gender impacts. Cooking with inefficient fuels consumes a lot of energy, and even more when water needs to be boiled before drinking. But do households with higher incomes and more devices have a better chance of escaping poverty? Some do, but having higher incomes and mobile phones are not either prerequisites or guarantees of having basic needs satisfied. Richer households without access to electricity or sanitation are not spared from having malnourished children or health problems from using charcoal. Ironically, for most households, it is easier to obtain a mobile phone than a clean, nonpolluting fuel for cooking. Therefore, measuring progress via household income leads to an incomplete understanding of poverty and its deprivations.

So what? Are we arguing against the global south using more energy for development? No: instead of focusing on how much energy is used, we are pointing to the importance of collective services (like electricity, indoor sanitation and public transport) for alleviating the multiple deprivations of poverty. In addressing these issues we cannot shy away from asking why so many countries in the global south have such a low capacity to invest in those services. It has to do with the fact that poverty does not just happen: it is created via interlinked systems of wealth extraction such as structural adjustment, or high costs of servicing national debts. Given that climate change is caused by the energy use of a rich minority in the global north but the consequences are borne by the majority in the poorer global south, human development is not only a matter of economic justice but also climate justice. Investing in vital collective services underpins both.

18-inch tall robots on four wheels zipping across city sidewalks "stopped people in their tracks as they whipped out their camera phones," reports the Florida Sun-Sentinel.

"The bots' mission: To deliver restaurant meals cheaply and efficiently, another leap in the way food comes to our doors and our tables." The semiautonomous vehicles were engineered by Kiwibot, a company started in 2017 to game-change the food delivery landscape...

In May, Kiwibot sent a 10-robot fleet to Miami as part of a nationwide pilot program funded by the Knight Foundation. The program is driven to understand how residents and consumers will interact with this type of technology, especially as the trend of robot servers grows around the country. And though Broward County is of interest to Kiwibot, Miami-Dade County officials jumped on board, agreeing to launch robots around neighborhoods such as Brickell, downtown Miami and several others, in the next couple of weeks... "Our program is completely focused on the residents of Miami-Dade County and the way they interact with this new technology. Whether it's interacting directly or just sharing the space with the delivery bots," said Carlos Cruz-Casas, with the county's Department of Transportation...

Remote supervisors use real-time GPS tracking to monitor the robots. Four cameras are placed on the front, back and sides of the vehicle, which the supervisors can view on a computer screen. [A spokesperson says later in the article "there is always a remote and in-field team looking for the robot."] If crossing the street is necessary, the robot will need a person nearby to ensure there is no harm to cars or pedestrians. The plan is to allow deliveries up to a mile and a half away so robots can make it to their destinations in 30 minutes or less.
Earlier Kiwi tested its sidewalk-travelling robots around the University of California at Berkeley, where at least one of its robots burst into flames. But the Sun-Sentinel reports that "In about six months, at least 16 restaurants came on board making nearly 70,000 deliveries...

"Kiwibot now offers their robotic delivery services in other markets such as Los Angeles and Santa Monica by working with the Shopify app to connect businesses that want to employ their robots." But while delivery fees are normally $3, this new Knight Foundation grant "is making it possible for Miami-Dade County restaurants to sign on for free."

A video shows the reactions the sidewalk robots are getting from pedestrians on a sidewalk, a dog on a leash, and at least one potential restaurant customer looking forward to no longer having to tip human food-delivery workers.

Long-time Slashdot reader Dputiger writes: Go looking for the difference between x86 and ARM CPUs, and you'll run into the idea of CISC versus RISC immediately. But 40 years after the publication of David Patterson and David Ditzel's 1981 paper, "The Case for a Reduced Instruction Set Computer," CISC and RISC are poor top-level categories for comparing these two CPU families.
ExtremeTech writes:
The problem with using RISC versus CISC as a lens for comparing modern x86 versus ARM CPUs is that it takes three specific attributes that matter to the x86 versus ARM comparison — process node, microarchitecture, and ISA — crushes them down to one, and then declares ARM superior on the basis of ISA alone. The ISA-centric argument acknowledges that manufacturing geometry and microarchitecture are important and were historically responsible for x86's dominance of the PC, server, and HPC market. This view holds that when the advantages of manufacturing prowess and install base are controlled for or nullified, RISC — and by extension, ARM CPUs — will typically prove superior to x86 CPUs.

The implementation-centric argument acknowledges that ISA can and does matter, but that historically, microarchitecture and process geometry have mattered more. Intel is still recovering from some of the worst delays in the company's history. AMD is still working to improve Ryzen, especially in mobile. Historically, both x86 manufacturers have demonstrated an ability to compete effectively against RISC CPU manufacturers.

Given the reality of CPU design cycles, it's going to be a few years before we really have an answer as to which argument is superior. One difference between the semiconductor market of today and the market of 20 years ago is that TSMC is a much stronger foundry competitor than most of the RISC manufacturers Intel faced in the late 1990s and early 2000s. Intel's 7nm team has got to be under tremendous pressure to deliver on that node.

Nothing in this story should be read to imply that an ARM CPU can't be faster and more efficient than an x86 CPU.
