Computer component maker Acer built a lightweight electric bike called the Acer ebii. Electrek reports: This lightweight 35 lb. (16 kg) e-bike features a number of gadgets and gizmos we have yet to spot in the industry, such as built-in AI designed to predictively control the transmission and make use of collision detection sensors for a safer ride. There's also proximity unlocking feature that the company says "automatically locks your bike when you leave and unlocks it again when you're nearby." My Gogoro electric scooter has a similar function, though that's a highway-capable vehicle.

Tracking capabilities are built into the ebii to help keep tabs on it 24/7. If the bike is ever stolen, it can be locked remotely and tracked using its built-in GPS locator. But don't think that you won't find typical bike parts here either, as the Acer ebii still features high-end components like a belt drive instead of a chain drive, 160mm hydraulic disc brakes, and 360-degree LED lighting. Airless tires are designed to remove the chance of flats, and a lefty-style fork does double duty as a conversation piece and a fancy weight saver.

There's also a 460 Wh electric bicycle battery that is said to offer a range of up to 68 miles (110 km) per charge. A top speed of 15 mph (25 km/h) and a 250W rear hub motor look to keep the bike within European and Asian power and speed limits. There's no hand throttle, which means riders will have to rely on pedal assist that is activated when the rider spins the pedals. It appears that there's some confusion about the 2.5-hour charger included with the bike, as some in the industry seem to think it can be used to charge phones and batteries as well. In fact, it's actually the e-bike's removable battery itself that can function as a portable power station to charge up your mobile devices. Pricing and availability are not yet available. But there is a launch video to build up excitement.

In a blog post shared last week, Ingka, the legal entity responsible for most of Ikea's stores, says it now has a total of 100 autonomous drones counting stock in its warehouses during nonoperational hours. The Verge reports: Ikea first partnered with the drone-making company Verity in 2020 to deploy the drones in Switzerland, but now, the company says they're zipping around 16 locations across Belgium, Croatia, Slovenia, Germany, Italy, and the Netherlands. The Swedish furniture giant says the drones help improve the accuracy of product availability and also support "a more ergonomic workplace," as it saves employees from counting stock manually.

Verity, which specializes in creating self-flying drones for warehouses and even concerts, was founded by Raffaello D'Andrea, one of the creators of Kiva Systems, or what's now called Amazon Robotics. As noted by D'Andrea in 2020, the drones work by taking off from a charging station and then going to each pallet in the warehouse to capture images, videos, and 3D depth scans of the items. Once the job is done, the drones return to their charging stations to download the collected data. The drones not only count inventory but also help employees determine if something's missing or in the wrong spot.

After almost 17 years online, file-hosting veteran Zippyshare will shut down at the end of the month. TorrentFreak: Founded in 2006, Zippyshare was known for its free, no-nonsense, no-frills approach to storing files online. Having changed very little over the years, Zippyshare's operators say the platform is now a dinosaur that costs too much to run in a world where ad-blocking is widespread. Zippyshare said, "Since 2006 we have been on the market in an unchanged form, that is, as ad financed/free file hosting. However, you have been visiting in less and less over the years, as the arguably very simple formula of the services we offer is slowly running out of steam. I guess all the competing file storage service companies on the market look better, offer better performance and more features. No one needs a dinosaur like us anymore."

An anonymous reader shares this report from Phoronix: For over a half-decade ASUS has been selling the Tinker Board devices as their line of Raspberry Pi alternatives. To date the ASUS Tinker Board single board computers have all been Arm-based while now they have launched their first RISC-V board, the Tinker V.

The ASUS Tinker V is their first RISC-V single board computer and intended for the industrial IoT (Internet of Things) developer community. The ASUS Tinker V is set to officially run Debian Linux and Yocto while surely with time more Linux distributions will be supported.... Being IoT focused, there isn't any display support. Those interested in learning more about the ASUS Tinker V can do so via tinker-board.asus.com.
The Register notes that Asus "is offering at least five years of support for Tinker V... Dedicated on-site technical support is also available to shorten customer development cycles and accelerate application deployment." The move shows that the RISC-V open-source instruction set architecture continues to garner support. The last RISC-V Summit in San Jose saw the launch of a family of datacenter-class processors based on the architecture from Ventana Micro Systems, while XMOS unveiled new high-performance microcontrollers using RISC-V.

According to Asus, Tinker V samples will be available in Q2 of this year, but it did not disclose a date for full availability or pricing.

Slashdot reader Prahjister knows what a system on a chip is. But that's part of the problem: I recently started hearing the term SoC at work when referring to digital signage hardware. This has really triggered me.... It is like when I heard people refer to a PC as a CPU.

I tried to speak to my colleagues and dissuade them from using this term in this manner with no luck. Am I wrong trying to dissuade them for this?
Maybe another question would be: Are there technical malapropisms that drive you crazy? Share your own thoughts and experiences in the comments.

And when should you call hardware a 'SoC'?

"Minnesota regulators said Thursday they're monitoring the cleanup of a leak of 400,000 gallons of radioactive water from Xcel Energy's Monticello nuclear power plant," reports the Associated Press, "and the company said there's no danger to the public." "Xcel Energy took swift action to contain the leak to the plant site, which poses no health and safety risk to the local community or the environment," the Minneapolis-based utility said in a statement. While Xcel reported the leak of water containing tritium to state and federal authorities in late November, the spill had not been made public before Thursday.

State officials said they waited to get more information before going public with it.... "Now that we have all the information about where the leak occurred, how much was released into groundwater, and that contaminated groundwater had moved beyond the original location, we are sharing this information," said Minnesota Pollution Control Agency spokesman Michael Rafferty, adding the water remains contained on Xcel's property and poses no immediate public health risk.

The company said it notified the federal Nuclear Regulatory Commission and the state on Nov. 22, the day after it confirmed the leak, which came from a pipe between two buildings. Since then, it has been pumping groundwater, storing and processing the contaminated water, which contains tritium levels below federal thresholds. "Ongoing monitoring from over two dozen on-site monitoring wells confirms that the leaked water is fully contained on-site and has not been detected beyond the facility or in any local drinking water," the Xcel Energy statement said.

When asked why Xcel Energy didn't notify the public earlier, the company said: "We understand the importance of quickly informing the communities we serve if a situation poses an immediate threat to health and safety. In this case, there was no such threat."

The UK Space Agency said Friday it would back research by Rolls-Royce looking at the use of nuclear power on the moon. CNBC reports: In a statement, the government agency said researchers from Rolls-Royce had been working on a Micro-Reactor program "to develop technology that will provide power needed for humans to live and work on the Moon." The UKSA will now provide [around $3.52 million] of funding for the project, which it said would "deliver an initial demonstration of a UK lunar modular nuclear reactor."

Rolls-Royce is set to work with a range of organizations on the project, including the University of Sheffield's Advanced Manufacturing Research Centre and Nuclear AMRC, and the University of Oxford. "Developing space nuclear power offers a unique chance to support innovative technologies and grow our nuclear, science and space engineering skills base," Paul Bate, chief executive of the UK Space Agency, said. Bate added that Rolls-Royce's research "could lay the groundwork for powering continuous human presence on the Moon, while enhancing the wider UK space sector, creating jobs and generating further investment." According to the UKSA, Rolls-Royce [...] is aiming "to have a reactor ready to send to the Moon by 2029."

An anonymous reader quotes a report from Ars Technica: A public pool in the UK is expected to save [about $24,000] and cut carbon emissions by 25.8 tons annually by warming a 25-meter children's pool with waste heat from a data center from startup Deep Green. UK-based Deep Green is a newcomer in the data-center heat game and is making its entrance notable by putting a monetary figure on potential savings, which are fueled by the heat's low, low rate of free. Deep Green's paying customers are machine-learning and AI firms seeking computing resources. As reported by Datacenter Dynamics on Tuesday, clients can leverage Deep Green's 28 kW system with high-performance computing (HPC) capabilities. The HPC cluster at the Exmouth Leisure Centre swimming pool has 12 four-CPU cards and could eventually be used for cloud services and video rendering, Deep Green CEO Mark Bjornsgaard told the publication. According to the BBC , the server is about the size of a washing machine.

The computers are submerged in mineral oil that captures heat that gets transferred into pool water with a heat exchanger. The pool still has a gas boiler to boost the water's temperature if required. Deep Green claims it's transferring about 96 percent of the energy used by its computers and reducing a pool's gas heat usage by 62 percent. Deep Green is paying the Exmouth Leisure Centre for all the electricity its data center uses, as well as any setup costs, and the Exmouth Leisure Centre gets the heat for free.

Deep Green CTO Mat Craggs told Datacenter Dynamics: "Our expected heat transfer from the kit is 139,284 kWh a year, equivalent to 62 percent of the pool's heat needs." He noted that adding more servers to the tub could extend the figure to 70 or 80 percent. Deep Green's data center can heat the Exmouth Leisure Centre's 25 meter pool to 86 degrees Fahrenheit for about 60 percent of the time, BBC reported. The startup has plans to set up data centers in seven more UK locations and has a 2023 target of 20 locations.

An anonymous reader quotes a report from Ars Technica: The creators of the all-open source MNT Reform laptop are getting nearer to launching its handheld counterpart: The crowdfunding campaign for the 7-inch MNT Pocket Reform has officially launched and is also serving as a de-facto preorder system for the device. The cheapest version of the Pocket Reform starts at $899, and it's also being offered in purple for $969 or in a bundle with a 1TB SSD, carrying case, handbook, and poster for $1,299. All versions are currently slated to ship in mid-October.

Like the full-size Reform, the pocket version uses open source hardware and a mechanical keyboard (buyers can choose either white or red Kalih switches). But the pocket version uses a 7-inch 1920x1200 LCD screen instead of a 12.5-inch version and comes with fewer and smaller ports (two USB-C, one micro HDMI, a microSD port, and one ix industrial mini Ethernet port). Its keyboard also comes with an individually programmable RGB backlight, and its trackball-style pointing device has been downsized to fit into the smaller design. The Pocket Reform also includes built-in Wi-Fi and Bluetooth, 128GB of built-in eMMC storage, and an expansion slot for 4G cellular connectivity. The device will also boot from microSD cards or an NVMe SSD installed in the device's M.2 slot. Its 8000 mAh batteries will allow it to run for about four hours. MNT warns in its blog post that "risks and challenges" could delay the October shipping timeline:

"Pocket Reform has hundreds of electronic components. We tried to pick them so that there will be enough stock when we get around to manufacturing the boards, but it's always possible that there could be a sudden component shortage or increase in price. If that should happen, we would have to re-engineer the affected PCB and exchange the part, causing a delay in continued production. We had to adapt our products several times during the global chip crisis, so we are confident that we'll be able to work around any difficulties. Should any situation arise that would delay the estimated shipping timeline, backers will be informed promptly via project updates."

An anonymous reader quotes a report from Ars Technica: Today, the federal government's Joint Office of Energy and Transportation opened up applications for a $2.5 billion program to expand electric vehicle charging infrastructure in underserved communities. The Charging and Fueling Infrastructure Discretionary Grant Program was authorized along with the $5 billion National Electric Vehicle Infrastructure Formula Program as part of the Infrastructure Investment and Jobs Act of 2021. For starters, the Joint Office is making $700 million available for EV chargers -- but also other alternative fuels including hydrogen and natural gas.

The CFI program actually encompasses two discrete $1.25 billion grant programs. The first is for community charging and fueling grants in both urban and rural areas, particularly in underserved and disadvantaged communities, including low- and moderate-income neighborhoods as well as neighborhoods with a low ratio of private parking. The other half of the money is for the alternative fuel corridor grants, which will fund the deployment of EV chargers and other alternative fuel infrastructure along designated alternative fuel corridors. "It's critical that we build a national charging network that provides EV drivers with the right type of charging in the right location -- whether that's high-powered charging on highway corridors and in urban hubs or Level 2 charging where EV drivers or riders live, work, and play," said Joint Office Executive Director Gabe Klein. "By working with cities and communities through the CFI Program to get this mix right, we can ensure that everyone has convenient and affordable access to riding and driving electric."

When Microsoft invested $1 billion in OpenAI in 2019, it agreed to build a massive, cutting-edge supercomputer for the artificial intelligence research startup. The only problem: Microsoft didn't have anything like what OpenAI needed and wasn't totally sure it could build something that big in its Azure cloud service without it breaking. From a report: OpenAI was trying to train an increasingly large set of artificial intelligence programs called models, which were ingesting greater volumes of data and learning more and more parameters, the variables the AI system has sussed out through training and retraining. That meant OpenAI needed access to powerful cloud computing services for long periods of time. To meet that challenge, Microsoft had to find ways to string together tens of thousands of Nvidia's A100 graphics chips -- the workhorse for training AI models -- and change how it positions servers on racks to prevent power outages. Scott Guthrie, the Microsoft executive vice president who oversees cloud and AI, wouldn't give a specific cost for the project, but said "it's probably larger" than several hundred million dollars. [...] Now Microsoft uses that same set of resources it built for OpenAI to train and run its own large artificial intelligence models, including the new Bing search bot introduced last month. It also sells the system to other customers. The software giant is already at work on the next generation of the AI supercomputer, part of an expanded deal with OpenAI in which Microsoft added $10 billion to its investment.

"Twelve years after the triple reactor meltdowns at the Fukushima Daiichi nuclear power plant, Japan is preparing to release a massive amount of treated radioactive wastewater into the sea," writes the Associated Press. "Japanese officials say the release is unavoidable and should start soon.

"Dealing with the wastewater is less of a challenge than the daunting task of decommissioning the plant. That process has barely progressed, and the removal of melted nuclear fuel hasn't even started." Massive amounts of fatally radioactive melted nuclear fuel remain inside the reactors. Robotic probes have provided some information but the status of the melted debris is largely unknown. kira Ono, who heads the cleanup as president of TEPCO's decommissioning unit, says the work is "unconceivably difficult."

Earlier this year, a remote-controlled underwater vehicle successfully collected a tiny sample from inside Unit 1âs reactor — only a spoonful of about 880 tons of melted fuel debris in the three reactors. That's 10 times the amount of damaged fuel removed at the Three Mile Island cleanup following its 1979 partial core melt.

Trial removal of melted debris will begin in Unit 2 later this year after a nearly two-year delay. Spent fuel removal from Unit 1 reactor's cooling pool is to start in 2027 after a 10-year delay. Once all the spent fuel is removed the focus will turn in 2031 to taking melted debris out of the reactors.... The government has stuck to its initial 30-40 year target for completing the decommissioning, without defining what that means....

Some experts say it would be impossible to remove all the melted fuel debris by 2051.
Meanwhile, groundwater is creating 130 tons of contaminated water each day, according to the article. The tanks holding that water "are 96% full and expected to reach their capacity of 1.37 million tons in the fall."

"Based on initial data review, vehicle is healthy," Relativity Space tweeted today. "More info to follow on cause of aborts today. Thanks for playing."

Remaining back on the launchpad is the largest 3D printed object ever to exist. And they're still hoping to launch it into space.

They'd planned a launch this morning from Cape Canaveral, Florida of a 110-foot rocket (33.5 meters) on a mission they're calling GLHF — "Good Luck, Have Fun".

The rocket's makers — California-based Relativity Space — call it "the world's first 3D printed rocket." A full 85% of the rocket's weight comes from 3D printed parts, explains Wired, and "only the computing system, electronics, and readily available parts like fasteners were not." Named Terran 1, the 7.5-foot-wide rocket (2.2 meters) inaugurates the company's ambitious plans for 3D printing in space: Relativity Space wants to use Terran 1 to (comparatively) cheaply lift satellites for other companies and NASA into Earth orbit. It also plans to construct Terran R, a larger, more powerful, fully reusable rocket that the company hopes will compete with SpaceX's Falcon 9, which has a smaller payload capacity and only reuses the rocket's first stage. In late 2024, Relativity plans to test using Terran R to launch payloads to Mars; another startup, Impulse Space, will provide the lander.
From the company's web site: Like its structure, all Relativity engines are 3D printed and use liquid oxygen and liquid natural gas, which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars.
The tagline for the company's Twitter feed says they're "Building humanity's multiplanetary future." And excitement is running high, reports Spaceflight Now" "There are a number of firsts here potentially on this rocket," said Josh Brost, vice president of revenue operations at Relativity Space....

"Hard to believe the day is nearly here to launch Terran 1, our first rocket!" Tim Ellis, co-founder and CEO of Relativity Space tweeted Tuesday....

The company now boasts some 1,000 employees, a million-square-foot headquarters and factory in Long Beach, California, and $1.3 billion in venture capital and equity fundraising, including an early $500,000 investment from billionaire Mark Cuban. In 2021, the company reached a valuation of $4.2 billion before launching any rockets....

"No new company has ever had their liquid rocket make it to space on their first attempt," Brost, also a former engineer and manager at SpaceX, told Spaceflight Now in a pre-launch interview. "So if everything goes incredibly well, and we achieve orbit on our first launch ... that would be a remarkable milestone for us, which we would be, of course, over the moon excited about. But that doesn't define success for us."
Wired adds that they're not the only company working on space-related 3D printing: Australia's Fleet Space has already been producing lightweight, 3D-printed radio frequency antennas for satellites. Next year, using printers half the size of a bus, they plan to create a satellite constellation called Alpha that will be entirely 3D-printed.... Flavia Tata Nardini, the company's CEO, believes space-based 3D printing is coming next. "In my ideal future, in 10 to 15 years, I won't have to launch satellites from here; I can build them up there."

On March 1st, a European Union regulation went into effect that effectively bans 8K TVs. This is because they exceed the new lower Energy Efficiency Index (EEI) limit that set the maximum power consumption level for all TVs at 90W, which is significantly lower than the 190W that new 8K TVs can consume. According to Tom's Guide, Samsung "seems to have already developed a workaround for this 8K TV ban." From the report: The ban is specifically based on the EEI power consumption numbers, so if you can manufacture an 8K TV that consumes less than 90W then you are in the clear. Because of this loophole, Samsung has decided to ship its 8K TVs with low-powered default settings. According to AV Magazine, the new Samsung 8K TVs will come out of the box with a "brightness-limiting eco mode" as the default brightness setting. This will allow the TVs to still meet the EEI limit while maintaining their 8K resolution.

But does this mean that Europeans will be limited to low brightness settings if they want 8K resolution? Turns out, the answer to that is, no. The E.U. regulation requires that the TVs be energy efficient out of the box, but once users have them set up, they can change to a higher brightness setting and watch to their heart's content, even though their 8K TV will now consume more power than the 90W limit set by the EEI. Other manufacturers will likely find workarounds for the E.U. regulations if Samsung's workaround is successful [...].

williamyf writes: The fine folks at Backblaze have published their first ever report that includes their SSD fleet. To the surprise of no one, SSDs are more more reliable (0.98% AFR) than HDDs (1.64% AFR). The surprising thing thing was how small the difference is (0.66% AFR).

A TL;DR article by well regarded storage reporter Chris Mellor is here. Also worthy of note: S.M.A.R.T. attribute usage among SSD makers is neither standardized, nor very smart:

"Klein notes that the SMART (Self-Monitoring, Analysis, and Reporting Technology) used for drive state reporting is applied inconsistently by manufacturers. "Terms like wear leveling, endurance, lifetime used, life used, LBAs [Logical Block Address] written, LBAs read, and so on are used inconsistently between manufacturers, often using different SMART attributes, and sometimes they are not recorded at all."

That means you can't use such SMART statistics to make valid comparisons between the drives. "Come on, manufacturers. Standardize your SMART numbers."

An anonymous reader quotes a report from Ars Technica: HP customers are showing frustration online as the vendor continues to use firmware updates to discourage or, as users report, outright block the use of non-HP-brand ink cartridges in HP printers. HP has already faced class-action lawsuits and bad publicity from "dynamic security," but that hasn't stopped the company from expanding the practice. Dynamic security is a feature used by HP printers to authenticate ink cartridges and prevent use of cartridges that aren't HP-approved. As the company explains: "Dynamic security relies on the printer's ability to communicate with the security chips or electronic circuitry on the cartridges. HP uses dynamic security measures to protect the quality of our customer experience, maintain the integrity of our printing systems, and protect our intellectual property. Dynamic security equipped printers are intended to work only with cartridges that have new or reused HP chips or electronic circuitry. The printers use the dynamic security measures to block cartridges using non-HP chips or modified or non-HP electronic circuitry. Reused, remanufactured, and refilled cartridges that reuse the HP chip or electronic circuitry are unaffected by dynamic security."

HP is set on continuing to use DRM to discourage its printer customers from spending ink and toner money outside of the HP family. "HP have updated their printers to outright ban 'non-HP' ink! They no longer shows the 'can't guarantee quality' message, but instead cancels your print completely until you inset a HP ink cartridge," Reddit user grhhull posted Tuesday. "After contacting HP, they advised 'this is due to the recent 'update' of all printers.'" It's unclear when HP issued updates for which model printers, but there are alleged customer complaints online stemming from late last year, showing plenty of customers surprised their printer no longer worked with non-HP ink cartridges after an update. Some pointed to third-party brands they had relied on for years.

HP community support threads include complaints about the OfficeJet 7740 and OfficeJet Pro 6970. HP lists both printers, as well as others, as able to circumnavigate dynamic security under specific conditions. However, HP's support page states this only applies to models manufactured before December 1, 2016. For more examples, there are comments on HP's support community suggesting that HP's OfficeJet 6978 and 6968 were recently affected. Both printers are discontinued, but HP's product pages make it clear that the fickle nature of dynamic security means that third-party ink could stop working at any time. And HP's dynamic security page also leaves the door open for the sudden bricking of functioning ink: "Firmware updates delivered periodically over the internet will maintain the effectiveness of the dynamic security measures," the page reads. "Updates can improve, enhance, or extend the printer's functionality and features, protect against security threats, and serve other purposes, but these updates can also block cartridges using a non-HP chip or modified or non-HP circuitry from working in the printer, including cartridges that work today."

James Temple reports via MIT Technology Review: In late January, a geothermal power startup began conducting an experiment deep below the desert floor of northern Nevada. It pumped water thousands of feet underground and then held it there, watching for what would happen. Geothermal power plants work by circulating water through hot rock deep beneath the surface. In most modern plants, it resurfaces at a well head, where it's hot enough to convert refrigerants or other fluids into vapor that cranks a turbine, generating electricity. But Houston-based Fervo Energy is testing out a new spin on the standard approach -- and on that day, its engineers and executives were simply interested in generating data.

The readings from gauges planted throughout the company's twin wells showed that pressure quickly began to build, as water that had nowhere else to go actually flexed the rock itself. When they finally released the valve, the output of water surged and it continued pumping out at higher-than-normal levels for hours. The results from the initial experiments -- which MIT Technology Review is reporting exclusively -- suggest Fervo can create flexible geothermal power plants, capable of ramping electricity output up or down as needed. Potentially more important, the system can store up energy for hours or even days and deliver it back over similar periods, effectively acting as a giant and very long-lasting battery. That means the plants could shut down production when solar and wind farms are cranking, and provide a rich stream of clean electricity when those sources flag.

There are remaining questions about how well, affordably, and safely this will work on larger scales. But if Fervo can build commercial plants with this added functionality, it will fill a critical gap in today's grids, making it cheaper and easier to eliminate greenhouse-gas emissions from electricity systems. "We know that just generating and selling traditional geothermal is incredibly valuable to the grid," says Tim Latimer, chief executive and cofounder of Fervo. "But as time goes on, our ability to be responsive, and ramp up and down and do energy storage, is going to increase in value even more."

An anonymous reader quotes a report from Ars Technica: On Monday, a group of AI researchers from Google and the Technical University of Berlin unveiled PaLM-E, a multimodal embodied visual-language model (VLM) with 562 billion parameters that integrates vision and language for robotic control. They claim it is the largest VLM ever developed and that it can perform a variety of tasks without the need for retraining. According to Google, when given a high-level command, such as "bring me the rice chips from the drawer," PaLM-E can generate a plan of action for a mobile robot platform with an arm (developed by Google Robotics) and execute the actions by itself.

PaLM-E does this by analyzing data from the robot's camera without needing a pre-processed scene representation. This eliminates the need for a human to pre-process or annotate the data and allows for more autonomous robotic control. It's also resilient and can react to its environment. For example, the PaLM-E model can guide a robot to get a chip bag from a kitchen -- and with PaLM-E integrated into the control loop, it becomes resistant to interruptions that might occur during the task. In a video example, a researcher grabs the chips from the robot and moves them, but the robot locates the chips and grabs them again. In another example, the same PaLM-E model autonomously controls a robot through tasks with complex sequences that previously required human guidance. Google's research paper explains (PDF) how PaLM-E turns instructions into actions.

PaLM-E is a next-token predictor, and it's called "PaLM-E" because it's based on Google's existing large language model (LLM) called "PaLM" (which is similar to the technology behind ChatGPT). Google has made PaLM "embodied" by adding sensory information and robotic control. Since it's based on a language model, PaLM-E takes continuous observations, like images or sensor data, and encodes them into a sequence of vectors that are the same size as language tokens. This allows the model to "understand" the sensory information in the same way it processes language. In addition to the RT-1 robotics transformer, PaLM-E draws from Google's previous work on ViT-22B, a vision transformer model revealed in February. ViT-22B has been trained on various visual tasks, such as image classification, object detection, semantic segmentation, and image captioning.

According to a report from Bloomberg's Mark Gurman, Apple is readying a new batch of Macs to launch "between late spring and summer." This includes a 15-inch MacBook Air and a new 24-inch iMac. From the report: Apple's next iMac desktop is at an advanced stage of development called engineering validation testing, or EVT, and the company is conducting production tests of the machine. The next iMac will continue to come in the same 24-inch screen size as the current model, which was announced in April 2021. The versions being tested also come in the same colors as the current iMac, a palette that includes blue, silver, pink and orange.

The new iMacs will, of course, be more powerful -- with a new M-series chip to replace the M1. There also will be some behind-the-scenes changes. The computer will see some of its internal components relocated and redesigned, and the manufacturing process for attaching the iMac's stand is different. While development of the new iMacs -- codenamed J433 and J434 -- has reached a late stage, it's not expected to go into mass production for at least three months. That means it won't ship until the second half of the year at the earliest. Still, this is a great development for anyone disappointed that Apple's all-in-one desktop hasn't been updated in nearly two years.

Aside from the iMac, Apple is scheduled to launch about three new Macs between late spring and summer, I'm told. Those three models are likely to be the first 15-inch MacBook Air (codenamed J515), the first Mac Pro with homegrown Apple chips (J180) and an update to the 13-inch MacBook Air (J513). The big remaining question is which processors these new Macs will run on. We already know the Mac Pro will include the M2 Ultra, which will provide up to 24 CPU cores, 76 graphics cores and the ability to top out the machine with at least 192 gigabytes of memory. We also know that Apple has developed the next iMac on the same timeline as the M3 chip, so I'd expect it to be one of the company's first M3-based machines.

An anonymous reader quotes a report from The Associated Press: A nuclear power plant in Georgia has begun splitting atoms in one of its two new reactors, Georgia Power said Monday, a key step toward reaching commercial operation at the first new nuclear reactors built from scratch in decades in the United States. The unit of Atlanta-based Southern Co. said operators reached self-sustaining nuclear fission inside the reactor at Plant Vogtle, southeast of Augusta. That makes the intense heat that will be used to produce steam and spin turbines to generate electricity.

A third and a fourth reactor were approved for construction at Vogtle by the Georgia Public Service Commission in 2009, and the third reactor was supposed to start generating power in 2016. The company now says Unit 3 could begin commercial operation in May or June. Unit 4 is projected to begin commercial operation sometime between this November and March 2024.

The cost of the third and fourth reactors was originally supposed to be $14 billion. The reactors are now supposed to cost more than $30 billion. That doesn't include $3.68 billion that original contractor Westinghouse paid to the owners after going bankrupt, which brings total spending to more than $34 billion. Georgia Power said Unit 3 would continue startup testing to show that its cooling system and steam supply system will work at the intense heat and pressure that a nuclear reactor creates. After that, operators are supposed to link the reactor to the electrical grid and gradually raise it to full power.
