The new Mac Studio started shipping to customers this week, giving product reviewers a chance to test Apple's "most capable chip ever." According to new benchmarks by YouTuber Luke Miani, the M2 Ultra features nearly double the GPU performance of last year's M1 Ultra, with notable performance improvements in other areas. 9to5Mac reports: While the M1 Max and M1 Ultra are blazing fast, the difference between the two wasn't as notable as some expected. In many tasks, the much cheaper M1 Max wasn't too far off from the top-end M1 Ultra variant, especially in video editing, photo editing, and 3D rendering. Despite the M1 Ultra literally being 2 M1 Max's fused, the performance was never doubled. For the M2 series, Apple has made some significant changes under the hood, especially in GPU scaling. In Luke's testing, he found that in some GPU heavy applications, like Blender 3D and 3DMark, the M2 Ultra was sometimes precisely twice the performance of M2 Max -- perfect GPU scaling! In Final Cut Pro exports, it nearly doubled again. He also found that the M2 Ultra doubled the GPU performance of the M1 Ultra in these same benchmarks -- a genuinely remarkable year-over-year upgrade.

The reason for the massive performance improvement is that Apple added a memory controller chip to the M2 generation that balances the load between all of M2 Ultra's cores -- M1 Ultra required the ram to be maxed out before using all cores. M1 Ultra was very good at doing many tasks simultaneously but struggled to do one task, such as benchmarking or rendering, faster than the M1 Max. With M2 Ultra, because of this new memory controller, Apple can now achieve the same incredible performance without the memory buffer needing to be maxed out. It's important to note that some applications cannot take advantage of the M2 Ultra fully, and in non-optimized applications, you should not expect double the performance.

Despite this incredible efficiency and performance, the better deal might be the M2 Max. In Luke's testing, the M2 Max performed very similarly or outperformed last year's M1 Ultra. In Blender, Final Cut Pro, 3DMark, and Rise of the Tomb Raider, the M2 Max consistently performed the same or better than the M1 Ultra. Instead of finding an M1 Ultra on eBay, it might be best to save money and get the M2 Max if you're planning on doing tasks that heavily utilize the GPU. While the GPU performance is similar, the M1 Ultra still has the advantage of far more CPU cores, and will outperform the M2 Max in CPU heavy workloads.

An anonymous reader quotes a report from Ars Technica: Intel does a lot of things, but it's mostly noted for making and shipping a lot of processors, many of which have been named after bodies of water. So, saying that the company is set to start sending out a processor called Tunnel Falls would seem unsurprising if it weren't for some key details. Among them: The processor's functional units are qubits, and you shouldn't expect to be able to pick one up on New Egg. Ever. Tunnel Falls appears to be named after a waterfall near Intel's Oregon facility, where the company's quantum research team does much of its work. It's a 12-qubit chip, which places it well behind the qubit count of many of Intel's competitors -- all of which are making processors available via cloud services. But Jim Clarke, who heads Intel's quantum efforts, said these differences were due to the company's distinct approach to developing quantum computers.

Intel, in contrast, is attempting to build silicon-based qubits that can benefit from the developments that most of the rest of the company is working on. The company hopes to "ride the coattails of what the CMOS industry has been doing for years," Clarke said in a call with the press and analysts. The goal, according to Clarke, is to make sure the answer to "what do we have to change from our silicon chip in order to make it?" is "as little as possible." The qubits are based on quantum dots, structures that are smaller than the wavelength of an electron in the material. Quantum dots can be used to trap individual electrons, and the properties of the electron can then be addressed to store quantum information. Intel uses its fabrication expertise to craft the quantum dot and create all the neighboring features needed to set and read its state and perform manipulations.

However, Clarke said there are different ways of encoding a qubit in a quantum dot (Loss-DiVincenzo, singlet-triplet, and exchange-only, for those curious). This gets at another key difference with Intel's efforts: While most of its competitors are focused solely on fostering a software developer community, Intel is simultaneously trying to develop a community that will help it improve its hardware. (For software developers, the company also released a software developer kit.) To help get this community going, Intel will send Tunnel Falls processors out to a few universities: The Universities of Maryland, Rochester, Wisconsin, and Sandia National Lab will be the first to receive the new chip, and the company is interested in signing up others. The hope is that researchers at these sites will help Intel characterize sources of error and which forms of qubits provide the best performance. "Overall, Intel has made a daring choice for its quantum strategy," concludes Ars' John Timmer. "Electron-based qubits have been more difficult to work with than many other technologies because they tend to have shorter life spans before they decohere and lose the information they should be holding. Intel is counting on rapid iteration, a large manufacturing capacity, and a large community to help it figure out how to overcome this. But testing quantum computing chips and understanding why their qubits sometimes go wrong is not an easy process; it requires highly specialized refrigeration hardware that takes roughly a day to get the chips down to a temperature where they can be used."

"The company seems to be doing what it needs to overcome that bottleneck, but it's likely to need more than three universities to sign up if the strategy is going to work."

An anonymous reader quotes a report from Scientific American: It could be a new world record, although no one involved wants to talk about it. In the south of France, a collaboration among 35 countries has been birthing one of the largest and most ambitious scientific experiments ever conceived: the giant fusion power machine known as the International Thermonuclear Experimental Reactor (ITER). But the only record ITER seems certain to set doesn't involve "burning" plasma at temperatures 10 times higher than that of the sun's core, keeping this "artificial star" ablaze and generating net energy for seconds at a time or any of fusion energy's other spectacular and myriad prerequisites. Instead ITER is on the verge of a record-setting disaster as accumulated schedule slips and budget overruns threaten to make it the most delayed -- and most cost-inflated -- science project in history.

The ITER project formally began in 2006, when its international partners agreed to fund an estimated [$6.3 billion], 10-year plan that would have seen ITER come online in 2016. The most recent official cost estimate stands at more than [$22 billion], with ITER nominally turning on scarcely two years from now. Documents recently obtained via a lawsuit, however, imply that these figures are woefully outdated: ITER is not just facing several years' worth of additional delays but also a growing internal recognition that the project's remaining technical challenges are poised to send budgets spiraling even further out of control and successful operation ever further into the future.

The documents, drafted a year ago for a private meeting of the ITER Council, ITER's governing body, show that at the time, the project was bracing for a three-year delay -- a doubling of internal estimates prepared just six months earlier. And in the year since those documents were written, the already grim news out of ITER has unfortunately only gotten worse. Yet no one within the ITER Organization has been able to provide estimates of the additional delays, much less the extra expenses expected to result from them. Nor has anyone at the U.S. Department of Energy, which is in charge of the nation's contributions to ITER, been able to do so. When contacted for this story, DOE officials did not respond to any questions by the time of publication.

As first hinted at by Intel back in late April, Intel is embarking on a journey to redefine its client processor branding, the biggest such shift in the previous 15 years of the company. From a report: Having already made waves by altering its retail packaging on premium desktop chips such as the Core i9-11900K and Core i9-12900K, the tech giant aims to introduce a new naming scheme across its client processors, signaling a transformative phase in its client roadmap. This shift is due to begin in the second half of the year, when Intel will launch their highly anticipated Meteor Lake CPUs. Meteor Lake represents a significant leap forward for the company in regards to manufacturing, architecture, and design -- and, it would seem, is prompting the need for a fresh product naming convention.

The most important changes include dropping the 'i' from the naming scheme and opting for a more straightforward Core 3, 5, and 7 branding structure for Intel's mainstream processors. The other notable inclusion, which is now officially confirmed, is that Intel will bifurcate the Core brand a bit and place its premium client products in their own category, using the new Ultra moniker. Ultra chips will signify a higher performance tier and target market for the parts, and will be the only place Intel uses their top-end Core 9 (previously i9) branding.

Microsoft is starting to sell replacement components for its Surface devices. The software giant now supplies replacement parts in the Microsoft Store, allowing Surface owners to replace their displays, batteries, SSDs, and more. From a report: "We are excited to offer replacement components to technically inclined consumers for out-of-warranty, self repair," says Tim McGuiggan, VP of devices services and product engineering at Microsoft. "When purchasing a replacement component, you will receive the part and relevant collateral components (such as screws if applicable)." Tools to help you repair a Microsoft Surface device are sold separately by iFixit, which Microsoft partnered with in 2021 to sell official Surface repair tools. iFixit supplies tools like battery covers to protect against punctures during repair, debonding cradles to help cut the adhesive that holds screen glass in place, and a tool to properly replace a screen.

What Iran's military called "the first product of the quantum processing algorithm" of the Naval university appears to be a stock development board, available widely online for around $600. Motherboard reports: According to multiple state-linked news agencies in Iran, the computer will help Iran detect disturbances on the surface of water using algorithms. Iranian Rear Admiral Habibollah Sayyari showed off the board during the ceremony and spoke of Iran's recent breakthroughs in the world of quantum technology. The touted quantum device appears to be a development board manufactured by a company called Diligent. The brand "ZedBoard" appears clearly in pictures. According to the company's website, the ZedBoard has everything the beginning developer needs to get started working in Android, Linux, and Windows. It does not appear to come with any of the advanced qubits that make up a quantum computer, and suggested uses include "video processing, reconfigurable computing, motor control, software acceleration," among others.

"I'm sure this board can work perfectly for people with more advanced [Field Programmable Gate Arrays] experience, however, I am a beginner and I can say that this is also a good beginner-friendly board," said one review on Diligent's website. Those interested in the board can buy one on Amazon for $589. It's impossible to know if Iran has figured out how to use off-the-shelf dev boards to make quantum algorithms, but it's not likely.

According to the Wall Street Journal, the Biden administration is expected to allow leading semiconductor manufacturers from South Korea and Taiwan to continue and expand their chipmaking operations in China. From a report: Alan Estevez, undersecretary of commerce for industry and security, announced the decision at an industry gathering last week. The exemptions, initially granted for one year in October last year, were provided to several companies, including South Korea's Samsung Electronics and Taiwan Semiconductor Manufacturing, who have invested billions in building plants in China.

The decision to extend the exemptions reflects the challenges faced by U.S. authorities in isolating China from high-tech goods in a highly integrated global industry. The U.S. has been trying to keep advanced chips out of Chinese hands by limiting exports not only from American manufacturers but also those made by allies. However, U.S. and foreign chip makers have resisted these efforts, and governments in Asia and Europe have also pushed back. The most vocal criticism has come from South Korea, whose largest export market is China. Further reading: Ex-Samsung Executive Accused of Stealing Secrets for China Chip Factory

An anonymous reader quotes a report from Ars Technica: When should you be concerned about a NAS hard drive failing? Multiple factors are at play, so many might turn to various SMART (self-monitoring, analysis, and reporting technology) data. When it comes to how long the drive has been active, there are backup companies like Backblaze using hard drives that are nearly 8 years old. That may be why some customers have been panicked, confused, and/or angered to see their Western Digital NAS hard drive automatically given a warning label in Synology's DiskStation Manager (DSM) after they were powered on for three years. With no other factors considered for these automatic flags, Western Digital is accused of age-shaming drives to push people to buy new HDDs prematurely. The practice's revelation is the last straw for some users. Western Digital already had a steep climb to win back NAS customers' trust after shipping NAS drives with SMR (shingled magnetic recording) instead of CMR (conventional magnetic recording). Now, some are saying they won't use or recommend the company's hard drives anymore.

As users have reported online, including on Synology-focused and Synology's own forums, as well as on Reddit and YouTube, Western Digital drives using Western Device Digital Analytics (WDDA) are getting a "warning" stamp in Synology DSM once their power-on hours count hits the three-year mark. WDDA is similar to SMART monitoring and rival offerings, like Seagate's IronWolf, and is supposed to provide analytics and actionable items. The recommended action says: "The drive has accumulated a large number of power on hours [throughout] the entire life of the drive. Please consider to replace the drive soon." There seem to be no discernible problems with the hard drives otherwise.

Synology confirmed this to Ars Technica and noted that the labels come from Western Digital, not Synology. A spokesperson said the "WDDA monitoring and testing subsystem is developed by Western Digital, including the warning after they reach a certain number of power-on-hours." The practice has caused some, like YouTuber SpaceRex, to stop recommending Western Digital drives for the foreseeable future. In May, the YouTuber and tech consultant described his outrage, saying three years is "absolutely nothing" for a NAS drive and lamenting the flags having nothing to do with anything besides whether or not a drive has been in use for three years. A user on SynoForum discussed their "panic" upon seeing the label. And SpaceRex said one of its clients also panicked and quickly replaced the "warning" drives out of fear of losing business-critical data. "It is clearly predatory tactics by Western Digital trying to sell more hard drives," SpaceRex said in a June 10 video. "Users are also concerned that this could prevent people from noticing serious problems with their drive," adds Ars. "Further, you can't repair a pool with a drive marked with a warning label."

Some of the affected products with WDDA include the WD Red Pro, WD Red Plus, and WD Purple. A discussion post about how to disable WDDA via SSH can be found here.

20 miles west of Portland, engineers at an Intel lab are dunking expensive racks of servers "in a clear bath" made of motor oil-like petrochemicals, reports the Oregonian, where the servers "give off a greenish glow as they silently labor away on ordinary computing tasks." Intel's submerged computers operate just as they would on a dry server rack because they're not bathing in water, even though it looks just like it. They're soaking in a synthetic oil that doesn't conduct electricity. So the computers don't short out.

They thrive, in fact, because the fluid absorbs the heat from the hardworking computers much better than air does. It's the same reason a hot pan cools off a lot more quickly if you soak it in water than if you leave it on the stove.

As data centers grow increasingly powerful, the computers are generating so much heat that cooling them uses exorbitant amounts of energy. The cooling systems can use as much electricity as the computers themselves. So Intel and other big tech companies are designing liquid cooling systems that could use far less electricity, hoping to lower data centers' energy costs by as much as a third — and reducing the facilities' climate impact. It's a wholesale change in thinking for data centers, which already account for 2% of all the electricity consumption in the U.S... Skeptics caution that it may be difficult or prohibitively expensive to overhaul existing data centers to adapt to liquid cooling. Advocates of the shift, including Intel, say a transition is imperative to accommodate data centers' growing thirst for power. "It's really starting to come to a head as we're hitting the energy crisis and the need for climate action globally," said Jen Huffstetler, Intel's chief product sustainability officer...

Cooler computers can be packed more tightly together in data centers, since they don't need space for airflow. Computer manufacturers can pack chips together more tightly on the motherboard, enabling more computing power in the same space. And liquid cooling could significantly reduce data centers' environmental and economic costs. Conventional data centers' evaporative cooling systems require tremendous volumes of water and huge amounts of electricity...

Many other tech companies are backing immersion cooling, too. Google, Facebook and Microsoft are all helping fund immersion cooling research at Oregon State... [T]he timing may finally be right for data centers operators to make the shift away from air cooling to something far more efficient. Intel's Huffstetler said she expects to see liquid cooling become widespread in the next three to five years.
The article notes other challenges:

• liquid adds more weight than some buildings' upper floors can support
• Some metals degrade faster in liquid than they do in air.
• And the engineers had to modify the servers by removing their fans — "because they serve no purpose while immersed."

Next year Intel introduces a new transistor — RibbonFET — and a new way of powering it called "PowerVia."

This so-called "backside power" approach "aims to separate power and I/O wiring, shifting power lines to the back of the wafer," reports Tom's Hardware, which "eliminates any possible interference between the data and power wires and increases logic transistor density." IEEE Spectrum explains this approach "leaves more room for the data interconnects above the silicon," while "the power interconnects can be made larger and therefore less resistive."

And Intel has already done some successful powering tests using it on Intel's current transistors: The resulting cores saw more than a 6 percent frequency boost as well as more compact designs and 30 percent less power loss. Just as important, the tests proved that including backside power doesn't make the chips more costly, less reliable, or more difficult to test for defects. Intel is presenting the details of these tests in Tokyo next week at the IEEE Symposium on VLSI Technology and Circuits...

[C]ores can be made more compact, decreasing the length of interconnects between logic cells, which speeds things up. When the standard logic cells that make up the processor core are laid out on the chip, interconnect congestion keeps them from packing together perfectly, leaving loads of blank space between the cells. With less congestion among the data interconnects, the cells fit together more tightly, with some portions up to 95 percent filled... What's more, the lack of congestion allowed some of the smallest interconnects to spread out a bit, reducing parasitic capacitance that hinders performance...

With the process for PowerVia worked out, the only change Intel will have to make in order to complete its move from Intel 4 to the next node, called 20A, is to the transistor... Success would put Intel ahead of TSMC and Samsung, in offering both nanosheet transistors and backside power.

The international space station is equpped with four 39-foot blankets (11.8-meters), reports CBS News. The first one was delivered in December of 2000 — and now it's time for some changes: Two astronauts ventured outside the International Space Station Friday and installed the fifth of six roll-out solar array blankets — iROSAs — needed to offset age-related degradation and micrometeoroid damage to the lab's original solar wings.

Floating in the Quest airlock, veteran Stephen Bowen, making his ninth spacewalk, and crewmate Woody Hoburg, making his first, switched their spacesuits to battery power at 9:25 a.m. EDT, officially kicking off the 264th spacewalk devoted to ISS assembly and maintenance and the seventh so far this year. NASA is in the process of upgrading the ISS's solar power system by adding six iROSAs to the lab's eight existing U.S. arrays. The first four roll-out blankets were installed during spacewalks in 2021 and 2022. Bowen and Hoburg installed the fifth during Friday's spacewalk and plan to deploy the sixth during another excursion next Thursday.

The two new iROSAs were delivered to the space station earlier this week in the unpressurized trunk section of a SpaceX cargo Dragon. The lab's robot arm pulled them out Wednesday and mounted them on the right side of the station's power truss just inboard the starboard wings... As the station sailed 260 miles above the Great Lakes, the 63-foot-long solar array slowly unwound like a window shade to its full length. Well ahead of schedule by that point, the spacewalkers carried out a variety of get-ahead tasks to save time next week when they float back outside to install the second new iROSA.

They returned to the airlock and began re-pressurization procedures at 3:28 p.m., bringing the 6-hour three-minute spacewalk to a close. With nine spacewalks totaling 60 hours and 22 minutes under his belt, Bowen now ranks fifth on the list of the world's most experienced spacewalkers.
"Combined with the 95-kilowatt output of the original eight panels, the station's upgraded system will provide about 215,000 kilowatts of power."

Longtime Slashdot reader WindBourne writes: "A shroud of smoke has sent solar power generation in parts of the eastern US plummeting by more than 50% as wildfires rage in Canada," reports Bloomberg. "Solar farms powering New England were producing 56% less energy at times of peak demand compared with the week before, according to the region's grid operator. Electricity generated by solar across the territory serviced by PJM Interconnection LLC, which spans Illinois to North Carolina, was down about 25% from the previous week."

Not mentioned in the article is that the wind generator output has also dropped. ["Wind power also dropped to 5% of total generation so far this week versus a recent high of 12% during the windy week ended May 12," reports Reuters. "That forced power generators to boost the amount of electricity generated by gas to 45% this week, up from around 40% in recent weeks."]

If forest fires can cut PV output by 50%, what would happen in real disasters when a nation most needs their electricity -- especially as we convert from fossil fuels (stored energy) to electricity? This will hopefully have politicians thinking in terms of national security, as well as anthropogenic global warming, when it comes to western grids.

Logitech is merging its gaming headset maker, Astro, and microphone manufacturer, Blue Microphones, into its Logitech G brand. While the Astro brand will continue as a premium console audio product series under Logitech G, the Blue brand will be phased out. The Verge reports: You can already see the transition playing out on Logitech's website, which still sells Yeti and even Snowball microphones that merely come "with Blue VO!CE" but no longer links to a distinct Blue website or product page. Astrogaming.com, however, still exists.

It's not clear why Logitech is minimizing its influential brands Astro and Blue, which defined the high-end gaming headset category and the microphone-for-streamers category, respectively, but I wonder if Logitech simply decided it had to choose between Blue and Yeti -- and Yeti was the name that rang out. However, Logitech's simply pitching it as a synergy play: you'll be able to control all your formerly Blue, Astro, and Logitech Creator products in the Logitech G software suite when all's said and done. Logitech bought gaming headset maker Astro for $85 million in 2017 and purchased mic manufacturer Blue Microphones for $177 million one year later.

Required Snark writes: Acer is selling computers in Russia even though they claimed they would abide by the Taiwanese government's commitment to the international embargo on western technology. The sales are through their Swiss subsidiary Acer Sales International SA. This subterfuge means Acer's position is nominally true even while they are breaking the embargo. Neither Russian, Swiss or Taiwanese government officials would comment on the report. According to Reuters, "Taiwan-based computer manufacturer Acer supplied at least $70.4 million worth of computer hardware to Russia between April 8, 2022 and March 31, 2023."

The actions aren't illegal because the shipments originated outside Taiwan, circumventing Taipei's sanctions against Russia. "Nor did they involve items restricted at the time of export by Switzerland's sanctions regime, which mirrors that of the European Union," adds Reuters. It does, however, contradict the company's statement on April 8 last year when it said it would "suspend its business in Russia."

GM has confirmed that it will adopt Tesla's North American Charging Standard (NACS) for its future electric vehicles, following in the footsteps of Ford. Electrek reports: This is likely the next step in a domino effect that should solidify NACS as the new charging standard for electric cars in North America. When Tesla announced last year that it opened up its proprietary charging connector to try to make it the industry standard in North America, we thought it might be too little too late, despite agreeing that Tesla's plug was a much superior design than the current CCS standard. However, we were proven wrong last month when Ford announced that it will integrate the NACS in its future electric vehicles.

GM CEO Mary Barra confirmed that General Motors will also adopt NACS with the help of Tesla in future electric vehicles. Barra made the announcement with Tesla CEO Elon Musk on Twitter. She said that the first vehicles with the plug will come in 2025 and like Ford, GM EV owners will all have access to Tesla's Supercharger network starting in 2024 with a CCS to NACS adapter. Like Ford, GM's Bara referenced the more efficient design of Tesla's connector and the "robustness" of Tesla's Supercharger network as reasons to adopt the standard. Barra said in a statement: "Our vision of the all-electric future means producing millions of world-class EVs across categories and price points, while creating an ecosystem that will accelerate mass EV adoption. This collaboration is a key part of our strategy and an important next step in quickly expanding access to fast chargers for our customers. Not only will it help make the transition to electric vehicles more seamless for our customers, but it could help move the industry toward a single North American charging standard."

An anonymous reader quotes a report from Ars Technica: Dell Technologies' Australia subsidiary misled online shoppers into thinking that adding a monitor to their purchase would get them a discount on the display, even though doing so sometimes resulted in customers paying a higher price for the monitor than if they had bought it on its own. That's according to a declaration by the Australian Federal Court on Monday. The deceptive practices happened on Dell's Australian website, but they serve as a reminder to shoppers everywhere that a strikethrough line or sale stamp on an online retailer doesn't always mean you're getting a bargain. On June 5, the Federal Court said Dell Australia was guilty of making "false or misleading representations with respect to the price" of monitors that its website encouraged shoppers to add to their purchase. The purchases were made from August 2019 to the middle of December 2021.

The website would display the add-on price alongside a higher price that had a strikethrough line, suggesting that the monitor was typically sold at the price with the line going through it but that customers would get a discount if they added it to their cart at purchase. (The Australian Competition & Consumer Commission, or ACCC, posted a screenshot example here.) However, the strikethrough prices weren't actually representative of what Dell was charging for the monitors for most of the time before the purported discount. In fact, the allegedly discounted price occasionally turned out to be a rip-off, as ACCC commission Liza Carver said in a statement today: "In some cases, consumers paid more for the add-on monitor advertised as 'discounted' than they would have paid if they had bought it as a stand-alone product, which is shocking."

The Australian Federal Court also found that Dell's Australian website used deceptive language, like "Includes x% off," "Total Savings" plus a dollar amount, "Discounted Price" and a dollar amount, and "Get the best price for popular accessories when purchased with this product." According to the ACCC, shoppers spent over $2 million Australian dollars ($1.33 million USD) on 5,300 add-on monitors during this time period. The Australian Federal Court ordered Dell Australia to give full or partial refunds to affected customers. The company must also hire an "independent compliance professional" and contact affected customers. The Australian Federal Court will take comment on further penalties Dell Australia should incur, which could include fines, at a future date. Dell told The Register: "As we acknowledged in November 2022 when the ACCC commenced these proceedings, due to an unrectified error on our part, our web page misrepresented the level of savings consumers could achieve by purchasing a monitor in conjunction with a desktop, laptop, or notebook."

Dell is looking into refunding customers, "plus interest," Dell's statement to The Register added, and the company is "taking steps to improve our pricing processes to ensure this sort of error does not happen again."

Researchers at the California Institute of Technology (Caltech) have successfully demonstrated the capability of steering power in a microwave beam from a satellite to targets in space, as well as transmitting some of that power to a detector on Earth. Science Magazine reports: The Caltech mission, funded by the Donald Bren Foundation and Northrop Grumman Corporation, aimed to go a step further with lightweight, inexpensive, and flexible components. The microwave transmitter was an array of 32 flat antennas packed onto a surface slightly larger than a dinner plate. By varying the timing of signals sent to the different antennas, the researchers could steer the array's beam. They pointed it at a pair of microwave receivers about a forearm's distance away and switched the beam from one receiver to the other at will, lighting up an LED on each.

The transmitted power was small, just 200 milliwatts, less than that of a cellphone camera light. But the team was still able to steer the beam toward Earth and detect it with a receiver at Caltech. "It was a proof of concept," says Caltech electrical engineer Ali Hajimiri. "It indicates what an overall system can do."

The Caltech spacecraft still has two more planned experiments. One is now testing 32 different varieties of solar cell to see which best survives the rigors of space. The second is a folded piece of ultralight composite material that will unfurl into a sail-like structure 2 meters across. Although the sail will not hold any solar cells, it is meant to test the kind of thin, flexible, and large deployments required for a future power station.

Millions of storage devices are being shredded each year, even though they could be reused. "You don't need an engineering degree to understand that's a bad thing," says Jonmichael Hands. From a report: He is the secretary and treasurer of the Circular Drive Initiative (CDI), a partnership of technology companies promoting the secure reuse of storage hardware. He also works at Chia Network, which provides a blockchain technology. Chia Network could easily reuse storage devices that large data centres have decided they no longer need. In 2021, the company approached IT Asset Disposition (ITAD) firms, who dispose of old technology for businesses that no longer need it. The answer came back: "Sorry, we have to shred old drives."

"What do you mean, you destroy them?" says Mr Hands, relating the story. "Just erase the data, and then sell them! They said the customers wouldn't let them do that. One ITAD provider said they were shredding five million drives for a single customer." Storage devices are typically sold with a five-year warranty, and large data centres retire them when the warranty expires. Drives that store less sensitive data are spared, but the CDI estimates that 90% of hard drives are destroyed when they are removed. The reason? "The cloud service providers we spoke to said security, but what they actually meant was risk management," says Mr Hands. "They have a zero-risk policy. It can't be one in a million drives, one in 10 million drives, one in 100 million drives that leaks. It has to be zero."

At WWDC today, Apple announced a new Mac Pro powered by the M2 Ultra chip. 9to5Mac reports: The chassis design of the machine appears to be the same as the 2019 Intel Mac Pro. The Mac Pro features eight Thunderbolt ports and six PCI slots for modular expansion. The base model config Mac Pro starts at $6999. Mac Pro with M2 Ultra features a 24-core CPU, up to 76-core GPU and 192 GB RAM. It also features two HDMI ports, dual 10-gigabit Ethernet, and a 32-core Neural Engine for machine learning tasks. It also features the latest wireless connectivity with Wi-Fi 6E and Bluetooth 5.3. You'll be able to order the new Mac Pro today via Apple.com.

Apple has announced a new operating system for its Vision Pro headset. Called visionOS, the operating system has been designed from the ground up for spatial computing and will have its own App Store where people can download Vision Pro apps and compatible iPhone and iPad apps. The Verge reports: The operating system is focused on displaying digital elements on top of the real world. Apple's video showed new things like icons and windows floating over real-world spaces. The primary ways to use the headset are with your eyes, hands, and your voice. The company described how you can look at a search field and just start talking to input text, for example. Or you can pinch your fingers to select something or flick them up to scroll through a window. The Vision Pro can also display your eyes on the outside of the headset -- a feature Apple calls "EyeSight."

It seems Apple envisions this in part as a productivity device; in one demo, it showed a person looking at things like a Safari window, Messages, and Apple Music window all hovering over a table in the real world. Apple also showed a keyboard hovering in midair, too. And the Vision Pro can also connect to your Mac so you can blow up your Mac's screen within your headset. It will also be a powerful entertainment device, apparently. You can make the screen really big by pinching a corner of a window (Apple demoed this with a clip of Foundation). You can display the screen on other backgrounds, including a cinema-like space or in front of Mt. Hood (Apple's suggestion!), thanks to a feature Apple calls Environments. You'll also be able to watch 3D movies on the device. And Disney is working on content for the headset, which could be a major way for people to get on board with actually using it to watch shows and movies -- Disney Plus will be available on day one, Disney CEO Bob Iger said during the show.

Apple Vision Pro will play games, too, and support game controllers; Apple showed somebody using the device with a PS5 DualSense headset. Over 100 Apple Arcade titles will be available to play on "day one," Apple said during its keynote. The Vision Pro also has a 3D camera, so you can capture "spatial" photos and video and look at those in the headset. And panorama photos can stretch around your vision while you're wearing the device. FaceTime is getting some "spatial" improvements, too; as described in Apple's press release, "Users wearing Vision Pro during a FaceTime call are reflected as a Persona -- a digital representation of themselves created using Apple's most advanced machine learning techniques -- which reflects face and hand movements in real time."
