Google Offers Genuine 'Pixel Fold' Repair Parts on iFixit. But Inner Screen Repairs Cost $900 (arstechnica.com) 31

"Since 2022, Google has worked with iFixit to offer official repair parts and guides for virtually all of the company's Pixel releases," according to the blog 9to5Google, which in June confirmed this would continue with Google's Pixel Fold. (They called the announcement "notable, as it will be the first foldable to date with support for DIY repair options.")

But Ars Technica has a warning about Google's "biggest and most expensive phone." The good news is Google has indeed started offering OEM replacement parts for the $1,800 phone on the repair site iFixit.

The bad news is a repair kit for the phone's inner display, a 7.6-inch flexible OLED screen, "will cost you a whopping $900." Even the "part only" option for $900 is the entire top half of the Pixel Fold. We're talking the display, the bezels around it, the entire metal frame and sides of the phone, the all-important hinge, side buttons, fingerprint sensor, and a whole bunch of wires. You wouldn't buy this and connect it to your original phone; you would part out your original phone and move a few pieces over into this, like the motherboard, batteries, cameras, and back plate...

The outer screen is a much more reasonable $160, while the rear glass cover and camera bump is $70. The batteries — there are two, remember — will run you $50 each...

Once you get the parts you need, it really feels like iFixit went all out in the guide department, with 32 different guides and "techniques" detailing how to disassemble the Pixel Fold.

Unity To Roll Back Some Key Aspects of Runtime Fee Policy (ign.com) 55

Unity has announced some key changes to its widely panned Runtime Fee policy, which spawned both derision and confusion from developers and the gaming community at large when it was unveiled earlier this month. From a report: It's easing up on some big aspects of the previously announced charges, removing the fee from the Unity Personal tier entirely, although it still remains in a revised form on the Unity Pro and Unity Enterprise tiers. In short, as originally announced, starting on Jan. 1, 2024, Unity would start charging developers a small fee every time someone downloads a game built on Unity's game engine after a certain threshold for minimum revenue and install count.

The different tiers of Unity plans - Unity Personal/Unity Plus, Unity Pro, and Unity Enterprise - had different thresholds and, per the original announcement, smaller developers using Unity Personal/Unity Plus would have to pay Unity $0.20 per install once their game passes $200,000 in revenue over the last 12 months and 200,000 life-to-date installs. Unity announced today, however, that there will be no Runtime Fee on games built on Unity Personal, which will remain free. They will also be increasing financial theshold of Unity Personal from $100,000 to $200,000 and will remove the requirement to use the Made with Unity splash screen.

US and China Launch Economic and Financial Working Groups With Aim of Easing Tensions (apnews.com) 11

The U.S. Treasury Department and China's Ministry of Finance launched a pair of economic working groups on Friday in an effort to ease tensions and deepen ties between the nations. From a report: Led by Treasury Secretary Janet Yellen and Vice Premier He Lifeng, the working groups will be divided into economic and financial segments. The working groups will "establish a durable channel of communication between the world's two largest economies," Yellen said in a series of tweets detailing the announcement. She said the groups will "serve as important forums to communicate America's interests and concerns, promote a healthy economic competition between our two countries with a level playing field for American workers and businesses."

The announcement follows a string of high-ranking administration officials' visits to China this year, which sets the stage for a possible meeting between President Joe Biden and his Chinese counterpart, Xi Jinping, in November at an Asia-Pacific economic conference in San Francisco. China is one of the United States' biggest trading partners, and economic competition between the two nations has increased in recent years. The two finance ministers have agreed to meet at a "regular cadence," the Treasury Department said in a news release.

Amazon's Eero Max 7 Mesh Router Adds Wi-Fi 7 - For a Whopping $600 30

Simon Hill, reporting for Wired: Every new hardware announcement is always described as "the best ever," but Amazon's new Eero Max 7 mesh might just be a real leap forward. This is Eero's first tri-band mesh router that utilizes the latest Wi-Fi 7 standard, promising roughly double the speeds of its previous flagship system up to 4.3 Gigabits per second. Theoretically, you can download a 4K movie in 10 seconds. The router has a larger design than its predecessor, which allows for more antennas, cooling without the need for a fan, and space for four Ethernet ports. But all this comes at a hefty price -- a single Eero Max 7 costs a whopping $600. It's early days for Wi-Fi 7, so as new models come out, we'll see these prices dramatically drop.

The Eero Max 7 supports the 2.4-GHz, 5-GHz, and 6-GHz bands and is fully backward compatible with all previous Wi-Fi versions; it runs the same TrueMesh software and app as other Eero systems, so it can be mixed and matched with any existing Eeros you have. However, you won't be able to take advantage of those Wi-Fi 7 upgrades and speeds without a Wi-Fi 7-supported device, which there are very few of right now. A common criticism of Eero routers (and most mesh Wi-Fi systems) is the lack of Ethernet ports. The Eero Pro 6E only offered two ports rated at 2.5 Gbps and 1 Gbps. Despite the Eero Max 7's larger size, it's still recognizably an Eero finished in shiny white plastic, but it's much larger than previous releases. That allows for four Ethernet ports, two rated at 10 Gbps and two at 2.5 Gbps. Accounting for packet overhead, tethered speeds max out at 9.4 Gbps.

Intel Unveils Meteor Lake Architecture (windowscentral.com) 59

Intel has taken the wraps off its forthcoming next-gen Meteor Lake processors following its successful 12th (Alder Lake) and 13th Gen (Raptor Lake) processors with its new E- and P-core design. WindowsCentral: Its first chip built on the Intel 4 process node with Foveros 3D packaging, Intel calls Meteor Lake its "biggest architectural shift in 40 years" and that it will "lay the foundation for innovations for the PC," as noted by Tim Wilson, VP, Design and Engineering Group and GM, SoC Design at Intel. Meteor Lake is Intel's next-gen CPU and the first built on the Intel 4 process, which is part of Intel's long-term goal of "5 nodes in 4 years." Previous generation naming would suggest it would be called Intel 14th Gen, but Intel is moving away from its older naming schema. Some reports have suggested Meteor Lake may reflect a reboot in generation numbers. Current rumors suggest Intel 14th Gen is simply a refresh of Raptor Lake, although Meteor Lake may play a part in that for laptops.

Meteor Lake processors are expected to ship in late 2023 or early 2024 in new laptops with thinner and lighter designs, better cooling, and much better battery life. The significant change for Meteor Lake is what Intel calls disaggregation, which means the breaking down of core components into separate 'tiles' on the SoC. Meteor Lake features four Tiles, including:
Compute Tile: New E-core and P-core microarchitecture, built on Intel 4 process technology
SoC Tile: Low power island E-cores, NPU, Wi-Fi 6E/7, native HDMI 2.1 and 8K HDR AV1 support
Graphics Tile: Integrated Intel Arc architecture
IO Tile: Thunderbolt 4 (and presumably Thunderbolt 5) and PCIe Gen5

Hundreds of Flying Taxis To Be Made In Ohio (apnews.com) 98

Under an agreement announced Monday, Joby Aviation will build hundreds of electric vertical takeoff and landing (eVTOL) aircraft in the same Ohio river valley where the Wright brothers pioneered human flight. The Associated Press reports: Joby's decision to locate its first scaled manufacturing facility at a 140-acre (57-hectare) site at Dayton International Airport delivers on two decades of groundwork laid by the state's leaders, Republican Lt. Gov. Jon Husted said. Importantly, the site is near Wright-Patterson Air Force Base and the headquarters of the U.S. Air Force Research Laboratories. The Wright brothers, Orville and Wilbur, lived and worked in Dayton. In 1910, they opened the first U.S. airplane factory there. To connect the historical dots, Joby's formal announcement Monday took place at Orville Wright's home, Hawthorn Hill, and concluded with a ceremonial flypast of a replica of the Wright Model B Flyer.

Joby's production aircraft is designed to transport a pilot and four passengers at speeds of up to 200 miles (321.87 kilometers) per hour, with a maximum range of 100 miles (160.93 kilometers). Its quiet noise profile is barely audible against the backdrop of most cities, the company said. The plan is to place them in aerial ridesharing networks beginning in 2025. The $500 million project is supported by up to $325 million in incentives from the state of Ohio, its JobsOhio economic development office and local government. With the funds, Joby plans to build an Ohio facility capable of delivering up to 500 aircraft a year and creating 2,000 jobs. The U.S. Department of Energy has invited Joby to apply for a loan to support development of the facility as a clean energy project.

Intel Shows Off Work on Next-Gen Glass Core Substrates, Plans Deployment Later in Decade (anandtech.com) 3

Intel has showed off its initial work on developing a glass core substrate and associated packaging process for its chips. AnandTech: As a result of their progress with research and development on the class cores, Intel is now planning on introducing glass core substrates to its products in the second half of this decade, allowing them to package chips in more complex, and ultimately higher-performing configurations. There's a lot to unpack from Intel's relatively short announcement, but at a high level, glass core substrates have been under research for over a decade as a replacement for organic substrates, which are widely used in current-generation processors.

Essentially the medium that typical silicon dies sit on, substrates play an important part in chip packaging. First and foremost, they provide the structural stability for a chip (silicon dies are quite fragile and flimsy), and they are also the means through which signals from silicon dies are carried, either to other on-package dies (i.e. chiplets), or to the large number of relatively sizable pins/pads on the back side of a chip. And, as chip sizes have increased over the years -- and the number of pins/signals required by high-end chips has, as well -- so has the need for newer and better materials to use as a substrate, which is what's been driving Intel's latest accomplishment.

Unity Says 'We Apologize,' Promises Changes to Previously-Announced Pricing (ign.com) 127

"We have heard you," Unity posted on Twitter/X on Sunday afternoon. "We apologize for the confusion and angst the runtime fee policy we announced on Tuesday caused."

"We are listening, talking to our team members, community, customers, and partners, and will be making changes to the policy. We will share an update in a couple of days. Thank you for your honest and critical feedback."

Within 90 minutes Unity's tweet had been viewed over 1 million times. Pushback had built over the last five days to Unity's announcement that next year they'd charge developers per game installation (beyond certain thresholds). IGN reports: Unity tried to clarify the policy, saying it will only count "net new installs" on any devices starting January 1 and devs would not be paying fees on re-installations, "fraudulent" installs via botnets and the like, trial version, web and streaming games, and charity-related installs. Unity also claimed that "90 percent of customers will not be affected by this change."

The development community did not take kindly to these proposed changes and clarifications, and many teams across the globe, including Rust 2 developer Facepunch Studios, said they won't be making their games in Unity now. Others, like Massive Monster, threatened to delete its Unity-made game Cult of the Lamb on January 1 should these changes happen.

The pushback got so severe that Unity offices in San Francisco and Austin had to close due to what it called a credible death threat.

'Public Resource' Wins 2012 Case. Judge Rules Posting Regulations Online is Fair Use (abajournal.com) 66

From an EFF announcement this week: Technical standards like fire and electrical codes developed by private organizations but incorporated into public law can be freely disseminated without any liability for copyright infringement, a federal appeals court ruled Tuesday.
The judge ruled that posting the materials constituted fair use — so the nonprofit group doing the posting won't be liable for copyright infringement. The American Bar Association Journal reports: The decision is a victory for public-domain advocate Carl Malamud and the group that he founded, Public.Resource.org. The group posts legal materials on its websites, including the standards developed by the three organizations that sued... "It has been over 10 years since plaintiffs filed suit in this case," said Malamud in a press release by the Electronic Frontier Foundation. "The U.S. Court of Appeals has found decisively in favor of the proposition that citizens must not be relegated to economy-class access to the law."
In 2012 Carl Malamud answered questions from Slashdot readers.

And now, finally, from the EFF's announcement: Tuesday's ruling by a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit upholds the idea that our laws belong to all of us, and we should be able to find, read, and share them free of registration requirements, fees, and other roadblocks... "In a nation governed by the rule of law, private parties have no business controlling who can read, share, and speak the rules to which we are all subject," EFF Legal Director Corynne McSherry said. "We are pleased that the Court of Appeals upheld what other U.S. courts, including the Supreme Court, have said for almost 200 years: No one should control access to the law."
Or, as the EFF puts it on another page, "Copyright cannot trump the essential public interest..."

US Energy Department Unveils Interactive Map Showing New Clean Energy Investments (energy.gov) 18

Long-time Slashdot reader destinyland writes: Thursday America's Energy Department released an interactive map showing America's clean energy investments, "for tracking the industrial revitalization happening across the country, fostered by a clean energy transition..."

The map aims to show how both the 2021 Bipartisan Infrastructure Law and the 2022 Inflation Reduction Act "are leading to announcements of historic levels of private sector investments in the United States," which the head of America's Energy Department credited for "a manufacturing renaissance across the U.S." A senior White House energy advisor specifically described it as "a clean energy boom" and called the map "a great resource for understanding the widespread and important impact this boom is having on communities all across our nation."

The announcement notes 500 "planned investments in at least 450 new or expanded clean energy manufacturing facilities, totaling over $160 billion in announced private and public sector investments" in solar, battery, and offshore wind manufacturing projects — as well as in electric vehicle assembly, components, and chargers. Ford received over $12 billion for battery pack/cell projects and EV assembly, along with billions more for Ford's joint venture with BlueOval SK to build a battery plant. And six of the projects are Tesla — totalling over $2 billion for projects in battery materials, cells, packs, and EV assembly.

KSMBD Finally Reaches 'Stable' State in Release Candidate for Linux Kernel 6.6 (theregister.com) 46

When Linus Torvalds announced Linux kernel 6.6's first release candidate, it included a newly-stable version of KSMBD, which is Samsung's in-kernel server for the SMB protocol (for sharing files/folders/printers over a network).

An announcement in 2021 had said that "For many cases the current userspace server choices were suboptimal either due to memory footprint, performance or difficulty integrating well with advanced Linux features."

LWN noted at the time that Linux has been using "the user-space Samba solution since shortly after the beginning." In a sense, ksmbd is not meant to compete with Samba; indeed, it has been developed in cooperation with the Samba project. It is, however, meant to be a more performant and focused solution than Samba is; at this point, Samba includes a great deal of functionality beyond simple file serving. Ksmbd claims significant performance improvements on a wide range of benchmarks...One other reason — which tends to be spoken rather more quietly — is that a new implementation can be licensed under GPLv2, while Samba is GPLv3.
The Register notes that when Samba switched to GPL 3, "one result was that Apple dropped Samba from Mac OS X and replaced it with its own, in-house server called SMBX." And they also remember that a month after its debut in 2021, "Linux sysadmins got to enjoy KSMBD's first security exploit." What's changed now is that it has faced considerable security testing and as a result it is no longer marked as experimental. It's been developed with the assistance of the Samba team, which itself documents how to use it. It's compatible with existing Samba configuration files. As the team says, "It is not meant to replace the existing Samba fileserver 'smbd', but rather be an extension and will integrate with Samba in the future...."

KSMBD is also important in that placing such core server functionality right inside the kernel represents a significant potential attack surface for crackers... The new bcachefs file system will not be going into kernel 6.6, and its developer is not happy.

"It's taken some time to get KSMBD to a state that was considered stable," points out Linux magazine. That time has come, and KSMBD is planned for Linux kernel 6.6.: But why is KSMBD important? First off, it promises considerable performance gains and better support for modern features such as Remote Direct Memory Access (RDMA)... KSMBD also adds enhanced security, considerably better performance for both single and multi-thread read/write, better stability, and higher compatibility. In the end, hopefully, this KSMBD will also mean easier share setups in Linux without having to jump through the same hoops one must with the traditional Samba setup.

New 'Inverse Vaccine' Shows Potential to Treat MS and Other Autoimmune Diseases (uchicago.edu) 73

This week saw an announcement from the University of Chicago's Pritzker School of Molecular Engineering. A new type of vaccine "has shown in the lab setting that it can completely reverse autoimmune diseases like multiple sclerosis and type 1 diabetes — all without shutting down the rest of the immune system." A typical vaccine teaches the human immune system to recognize a virus or bacteria as an enemy that should be attacked. The new "inverse vaccine" does just the opposite: it removes the immune system's memory of one molecule. While such immune memory erasure would be unwanted for infectious diseases, it can stop autoimmune reactions like those seen in multiple sclerosis, type I diabetes, or rheumatoid arthritis, in which the immune system attacks a person's healthy tissues. The inverse vaccine, described in Nature Biomedical Engineering, takes advantage of how the liver naturally marks molecules from broken-down cells with "do not attack" flags to prevent autoimmune reactions to cells that die by natural processes. Pritzker School of Molecular Engineering researchers coupled an antigen — a molecule being attacked by the immune system — with a molecule resembling a fragment of an aged cell that the liver would recognize as friend, rather than foe. The team showed how the vaccine could successfully stop the autoimmune reaction associated with a multiple-sclerosis-like disease...

Jeffrey Hubbell [lead author of the new paper] and his colleagues knew that the body has a mechanism for ensuring that immune reactions don't occur in response to every damaged cell in the body — a phenomenon known as peripheral immune tolerance, which is carried out in the liver. They discovered in recent years that tagging molecules with a sugar known as N-acetylgalactosamine (pGal) could mimic this process, sending the molecules to the liver where tolerance to them develops. "The idea is that we can attach any molecule we want to pGal and it will teach the immune system to tolerate it," explained Hubbell. "Rather than rev up immunity as with a vaccine, we can tamp it down in a very specific way with an inverse vaccine."

In the new study, the researchers focused on a multiple-sclerosis-like disease in which the immune system attacks myelin, leading to weakness and numbness, loss of vision and, eventually mobility problems and paralysis. The team linked myelin proteins to pGal and tested the effect of the new inverse vaccine. The immune system, they found, stopped attacking myelin, allowing nerves to function correctly again and reversing symptoms of disease in animals. In a series of other experiments, the scientists showed that the same approach worked to minimize other ongoing immune reactions...

Initial phase I safety trials of a glycosylation-modified antigen therapy based on this preclinical work have already been carried out in people with celiac disease, an autoimmune disease that is associated with eating wheat, barley and rye, and phase I safety trials are under way in multiple sclerosis. Those trials are conducted by the pharmaceutical company Anokion SA, which helped fund the new work and which Hubbell cofounded and is a consultant, board member, and equity holder. The Alper Family Foundation also helped fund the research.

"There are no clinically approved inverse vaccines yet, but we're incredibly excited about moving this technology forward," says Hubbell.

Developers Respond To Unity's New Pricing Scheme (theverge.com) 107

Unity announced a new pricing model this week, charging developers per game install beyond certain thresholds. This move has faced severe backlash from developers, criticizing Unity's communication, clarity, trust issues, and perceived exploitation of indie teams. The Verge adds: Many developers and even publishers took to social media to register their anger and to call on Unity to reverse its decision. [...] "This decision puts studios in a position where we might not be able to justify using Unity for our future titles," read a post on X (formerly Twitter) from developer Aggro Crab. "If these changes aren't rolled back, we'll be heavily considering abandoning our Unity expertise." Many developers shared a similar sentiment, explaining they were considering abandoning Unity as a game engine.

Other game developers, like Massive Monster, were more drastic, which, via the official account for its game Cult of the Lamb, threatened to delist the game entirely. Though the post was a tongue-in-cheek joke, it's one being repeated by other developers. "[Please] buy our game," posted the official Viewfinder account. "But don't install it after January 1, 2024." Other game makers wondered how Unity could put forth such a statement without considering all the ways it could negatively impact its users. According to a post on the Unity forums from someone who claimed to be an employee, objections were raised internally. "Know also that all of the concerns that are understandably blowing up at the moment have been raised internally by many weeks before this announcement," the alleged employee wrote. "Why it was decided to rush this out anyway in this way I can only speculate about."

NASA Names Chief of UFO Research; Panel Sees No Alien Evidence (reuters.com) 120

NASA on Thursday said it has named a new director of research into what the government calls "unidentified anomalous phenomenon," or UAP, while the U.S. space agency's chief said an expert panel that urged deeper fact-finding on the matter found no evidence of an extraterrestrial origin for these objects. You can read the study team's full report here (PDF). Reuters reports: Administrator Bill Nelson made the announcement about the new research chief -- without disclosing the person's identity -- after the independent panel of experts recommended in a new report that NASA increase its efforts to gather information on UAP and play a larger role in helping the Pentagon detect them. [...] The NASA panel, comprising experts in fields ranging from physics to astrobiology, was formed last year and held its first public meeting in June. "The NASA independent study team did not find any evidence that UAP have an extraterrestrial origin, but we don't know what these UAP are," Nelson said, adding that a goal of the agency is to "shift the conversation about UAP from sensationalism to science."

"The mission of NASA is to find out the unknown," Nelson said. "Whatever we find, we're going to tell you," Nelson added, promising transparency on any discoveries. The new UAP research director will handle "centralized communications, resources and data analytical capabilities to establish a robust database for the evaluation of future UAP," NASA said. Nelson told Reuters he does not know the name of the new director. Dan Evans, a senior research official in NASA's science unit and a member of the study team, said harassment that other panel members had received from the public during their work was "in part" why the new director's identity was being kept secret.

Unity Rushes To Clarify Price Increase Plan, as Game Developers Fume (axios.com) 71

Unity, the tech company behind one of the most popular engines for creating video games, is scrambling to clarify how a price increase for its services will work, after its announcement Tuesday morning broadly infuriated the game development community. From a report: The fees, which Unity said are essential for funding development of its tech, left many game makers wondering if having a hit game through Unity would cost them more money than they could make. Developers spoke throughout the day of delaying their games to switch to rival Epic Games' Unreal Engine or other services on X, the platform formerly known as Twitter. But by the evening, Unity exec Marc Whitten was updating Axios on the policies, potentially defusing some concerns raised by game creators.

The new "Runtime Fee" announced Tuesday morning is tied to a player's installations of a game, an action that previously didn't cost developers anything. With Unity's new plan, developers who use Unity's free tier of development services would owe Unity $0.20 per installation once their game hit thresholds of 200,000 downloads and earn $200,000 in revenue. Developers paying over $2,000 a year for a Unity Pro plan would have to hit higher thresholds and would be charged with lower fees. The newfee system will begin at the start of 2024. [...] After initially telling Axios earlier Tuesday that a player installing a game, deleting it and installing it again would result in multiple fees, Unity's Whitten told Axios that the company would actually only charge for an initial installation. (A spokesperson told Axios that Unity had "regrouped" to discuss the issue.) He hoped this would allay fears of "install-bombing," where an angry user could keep deleting and re-installing a game to rack up fees to punish a developer.

Startup Building Zinc-Based Alternatives to Lithium Batteries Granted $400M Loan from the US (popsci.com) 97

Popular Science reports that America's Department of Energy "is providing a nearly $400 million loan to a startup aimed at scaling the manufacturing and deployment of a zinc-based alternative to rechargeable lithium batteries."

If realized, Eos Energy's utility- and industrial-scale zinc-bromine battery energy storage system could provide cheaper, vastly more sustainable options for the country's burgeoning renewable power infrastructure... Unlike lithium-ion and lithium iron phosphate batteries, alternatives such as the Eos Z3 design rely on zinc-based cathodes alongside a water-based electrolyte, notes MIT Technology Review. This important distinction both increases their stability, as well as makes it incredibly difficult for them to support combustion. Zinc-bromine batteries meanwhile also boast lifespans as long as 20 years, while existing lithium options only manage between 10 and 15 years. What's more, zinc is considered the world's fourth most produced metal...

The U.S. Department of Energy also notes that "over time," Eos expects to source almost all of its materials within the U.S., thus better insulating its product against the market volatility and supply chain issues. While the Department of Energy previously issued similar loans to battery recycling and geothermal energy projects, last week's announcement marks the first funding offered to a manufacturer of lithium-battery alternatives.

MIT's article notes that Eos's semi-autonomous facility in Pennsylvania already produces around 540 megawatt-hours annually — and it isn't operating at full capacity. This new loan could boost factory toward full-power. The $398-million loan funds "up to four state-of-the-art production lines," according to the announcement from the U.S. Energy Department.

It notes that the technology is "specifically designed for long-duration grid-scale stationary battery storage that can assist in meeting the energy grids' growing demand with increasing amounts of renewable energy penetration." If finalized, the project is expected to manufacture 8 GWh of storage capacity annually by 2026. That is enough to provide electricity to over 300,000 average U.S. homes instantaneously or meet the annual electricity needs of approximately 130,000 homes if fully charged and discharged daily. The project is expected to create up to 50 union contractor construction jobs and as many as 650 new operations jobs when at full operational capacity...

Critically, Eos batteries are non-flammable and do not require active cooling to operate. The batteries can achieve 100% depth of discharge...

Nasdaq Receives SEC Approval For AI-Based Trade Orders (cointelegraph.com) 52

The SEC has approved the Nasdaq's request to operate the first exchange AI-driven order type. CoinTelegraph reports: Called the dynamic midpoint extended life order (M-ELO), the new system expands on the M-ELO automated order type by making it "dynamic," meaning it will use artificial intelligence to update and, essentially, recalibrate itself in real-time. Order types are a set of software instructions that execute specific trade pairs at exact market pricing thresholds. This form of automation has been around for a while, but the new AI-driven order type is the first of its kind to use real-time reinforcement learning AI to execute orders

This should have the follow-on effect of substantially speeding up orders placed with the system. In a blog post accompanying the approval announcement, Nasdaq states that dynamic M-ELO demonstrated a "20.3% increase in fill rates and an 11.4% reduction in mark-outs" during its research and testing. According to a data sheet published by Nasdaq: "Calculated on a symbol-by-symbol basis, this new functionality analyzes 140+ data points every 30 seconds to detect market conditions and optimize the holding period prior to which a trade is eligible to execute." By adjusting the holding periods for orders in real time, as opposed to the traditional system that simply applies static timeouts to orders, fill rates should increase without a significant increase in market impact.
