Drop Duchy is a deck-building, Tetris-like, Carcassonne-esque puzzler

If you build up a big area of plains on your board, you can drop your “Farm” piece in the middle, and it converts those plains into richer plains. Put a “Woodcutter” into a bunch of forest, and it harvests that wood and turns it into plains. Set down a “Watchtower,” and it recruits some archer units for every plains tile in its vicinity, and even more for richer fields. You could drop a Woodcutter next to a Farm and Watchtower, and it would turn the forests into plains, the Farm would turn the plains into fields, and the Watchtower would pick up more units for all those rich fields.

That kind of multi-effect combo, resulting from one piece you perfectly placed in the nick of time, is what keeps you coming back to Drop Duchy. The bitter losses come from the other side, like realizing you’ve leaned too heavily into heavy, halberd-wielding units when the enemy has lots of ranged units that are strong against them. Or that feeling, familiar to Tetris vets, that one hasty decision you made 10 rows back has doomed you to the awkward, slanted pile-up you find yourself in now. Except that lines don’t clear in Drop Duchy, and the game’s boss battles specifically punish you for running out of good places to put things.

There’s an upper strategic layer to all the which-square-where action. You choose branching paths on your way to each boss, picking different resources, battles, and trading posts. Every victory has you picking a card for your deck, whether military, production, or, later on, general “technology” gains. You upgrade cards using your gathered resources, try to balance or min-max cards toward certain armies or terrains, and try not to lose any one round by too many soldiers. You have a sort of “overall defense” life meter, and each loss chips away at it. Run out of money to refill it, and that’s the game.

New Switch 2 specs show large performance dip in undocked mode

Digital Foundry also notes that the Switch 2’s stated clock speeds can be tuned to higher theoretical maximums: 1.4 GHz for the GPU and 1.7 GHz for the CPU. Nintendo could eventually make use of this headroom for improved graphical performance and faster loading screens, as it did on the original Switch in 2019. And while developers can adjust the GPU clock rate used by their games, it’s unclear if they’ll be able to directly overclock to the theoretical maximum themselves.

System resources

As on the original Switch, 25 percent of the CPU cores and overall memory on the Switch 2 is reserved by the system for OS features and is thus inaccessible to game developers directly. Digital Foundry also notes that some GPU resources are reserved by the system OS, though it didn’t provide a precise measurement for this amount.

Using Game Chat on the Switch 2 could have a significant effect on system performance, according to Digital Foundry.

This time around, those system-level features include Game Chat, which offers the ability to stream gameplay and/or webcam video from up to four friends to a single system. Even with significant resources set aside by the OS, though, Digital Foundry notes that Game Chat has “a significant impact on system resources,” leading Nintendo to provide developers with a testing tool that “simulates API latency and L3 cache misses” that can happen when Game Chat is in use.

Aside from the core pixel-pushing hardware, the Switch 2 also adds a new separate File Decompression Engine, which can handle loading game data off of the system’s 256GB of on-board UFS memory and MicroSD Express expansion cards without taxing the CPU. And while the Switch 2’s portable screen includes support for variable refresh rates up to 120 Hz, there is currently no official support for VRR on HDMI displays connected to the system’s dock.

While it’s fun to look at numbers, the real proof of the Switch 2’s hardware power will be in the performance of its games. We look forward to having more direct comparisons of software performance when the console launches next month.

federal-agencies-continue-terminating-all-funding-to-harvard

Federal agencies continue terminating all funding to Harvard

On Tuesday, the federal government’s Joint Task Force to Combat Anti-Semitism announced that it had terminated research grants to Harvard totalling $450 million, spread out across eight federal agencies. The move comes on the heels of $2.2 billion in earlier cuts and an announcement that the university will be prevented from receiving any future grants. The ongoing campaign appears to be heading toward a point where no researchers at Harvard will receive federal funding.

The announcement reiterates accusations that are familiar from earlier federal funding terminations. It references antisemitic incidents during earlier protests about Israel’s actions in Gaza and the fact that the Harvard Law Review has taken steps to diversify the authors it publishes, which the government considers illegal discrimination. Notably, the letter does not mention any more recent events, nor Harvard’s efforts to address antisemitism on campus, saying:

Harvard’s campus, once a symbol of academic prestige, has become a breeding ground for virtue signaling and discrimination. This is not leadership; it is cowardice. And it’s not academic freedom; it’s institutional disenfranchisement. There is a dark problem on Harvard’s campus, and by prioritizing appeasement over accountability, institutional leaders have forfeited the school’s claim to taxpayer support.

It’s generally difficult to understand the big picture of these cuts and the reasons for them from this announcement. Instead, it has to be pieced together from the multitude of letters that individual agencies have sent Harvard.

Multiple federal agencies, including the Department of Energythe National Science Foundation, and the Department of Defense, also sent letters announcing the grant terminations on Tuesday. These sometimes contain more specific accusations, such as the Department of Energy letter, which specifically terms Harvard’s efforts to address past problems as insufficient. “Harvard has refused to take immediate, definitive and appropriate remedial action,” the letter said.

“Google wanted that”: Nextcloud decries Android permissions as “gatekeeping”

Nextcloud is a host-your-own cloud platform that wants to help you “Regain control over your data.” It contains products that allow for video chat, file storage, collaborative editing, and other stuff that reads a lot like a DIY Google Workspace replacement.

It’s hard to offer that kind of full replacement, though, if your Android app can’t upload anything other than media files. Since mid-2024, Nextcloud claims, Google has refused to reinstate the access it needs for uploading and syncing other file types.

“To make it crystal clear: All of you as users have a worse Nextcloud Files client because Google wanted that,” reads a Nextcloud blog post from May 13, attributed to its team. “We understand and share your frustration, but there is nothing we can do.”

Ars has reached out to Google for comment and will update this post with any response. A representative for NextCloud told Ars late Tuesday that the company had no update on its Android app.

Nextcloud states that it has had read and write access to all file types since its first Android app. In September 2024, a Nextcloud Android update with “All files access” was “refused out of the blue,” with a request that the app use “a more privacy aware replacement,” Nextcloud claims. The firm states it has provided background and explanations but received “the same copy-and-paste answers or links to documentation” from Google.

office-apps-on-windows-10-are-no-longer-tied-to-its-october-2025-end-of-support-date

Office apps on Windows 10 are no longer tied to its October 2025 end-of-support date

For most users, Windows 10 will stop receiving security updates and other official support from Microsoft on October 14, 2025, about five months from today. Until recently, Microsoft had also said that users running the Microsoft Office apps on Windows 10 would also lose support on that date, whether they were using the continually updated Microsoft 365 versions of those apps or the buy-once-own-forever versions included in Office 2021 or Office 2024.

Microsoft has recently tweaked this policy, however (as seen by The Verge). Now, Windows 10 users of the Microsoft 365 apps will still be eligible to receive software updates and support through October of 2028, “in the interest of maintaining your security while you upgrade to Windows 11.” Microsoft is taking a similar approach to Windows Defender malware definitions, which will be offered to Windows 10 users “through at least October 2028.”

The policy is a change from a few months ago, when Microsoft insisted that Office apps running on Windows 10 would become officially unsupported on October 14. The perpetually licensed versions of Office will be supported in accordance with Microsoft’s “Fixed Lifecycle Policy,” which guarantees support and security updates for a fixed number of years after a software product’s initial release. For Office 2021, this means Windows 10 users will get support through October of 2026; for Office 2024, this should extend to October of 2029.

Samsung reveals the super-slim Galaxy S25 Edge with a laughably small battery

While the body of the phone is just 5.8 mm thick, the camera modules stick out a few millimeters more, making the phone quite wobbly when you set it on a table. The cameras have to stick out to leave more space for the internals, which are pretty powerful. Inside, this phone is essentially unchanged from the other S25 phones, with a Snapdragon 8 Elite, 12GB of RAM, and either 256 or 512GB of storage. The battery will be a problem, though.

While the S25+ sports a passable 4,900 mAh cell, the super-slim S25 Edge has just 3,900 mAh of juice. That is a problem because the Snapdragon 8 Elite is a flagship processor designed for speed. While it’s relatively efficient in low-power mode, it will devour the Edge’s battery in short order if you’re playing games or multitasking. A 20 percent reduction in battery life compared to the Galaxy S25+, which is a one-day phone, is a tough sell.

Most smartphone manufacturers could never justify making such a strange, niche device. This is Samsung showing off its engineering skills, and the S25 Edge does look neat. But the novelty of a super-slim phone will probably wear off when you have to start plugging it in to get a boost mid-afternoon. It doesn’t even charge very fast, topping out at a mere 25 W. And you’ll be paying $1,099 for the privilege, which slots the Edge between the S25+ ($1,000) and the S25 Ultra ($1,300).

If you want a phone that is thin at the expense of everything else, you can order the Galaxy S25 Edge from Samsung or Best Buy. It comes in black, icy blue, and silver colors and will ship on May 30.

GOP sneaks decade-long AI regulation ban into spending bill

The reconciliation bill primarily focuses on cuts to Medicaid access and increased health care fees for millions of Americans. The AI provision appears as an addition to these broader health care changes, potentially limiting debate on the technology’s policy implications.

The move is already inspiring backlash. On Monday, tech safety groups and at least one Democrat criticized the proposal, reports The Hill. Rep. Jan Schakowsky (D-Ill.), the ranking member on the Commerce, Manufacturing and Trade Subcommittee, called the proposal a “giant gift to Big Tech,” while nonprofit groups like the Tech Oversight Project and Consumer Reports warned it would leave consumers unprotected from AI harms like deepfakes and bias.

Big Tech’s White House connections

President Trump has already reversed several Biden-era executive orders on AI safety and risk mitigation. The push to prevent state-level AI regulation represents an escalation in the administration’s industry-friendly approach to AI policy.

Perhaps it’s no surprise, as the AI industry has cultivated close ties with the Trump administration since before the president took office. For example, Tesla CEO Elon Musk serves in the Department of Government Efficiency (DOGE), while entrepreneur David Sacks acts as “AI czar,” and venture capitalist Marc Andreessen reportedly advises the administration. OpenAI CEO Sam Altman appeared with Trump in an AI datacenter development plan announcement in January.

By limiting states’ authority over AI regulation, the provision could prevent state governments from using federal funds to develop AI oversight programs or support initiatives that diverge from the administration’s deregulatory stance. This restriction would extend beyond enforcement to potentially affect how states design and fund their own AI governance frameworks.

Ana de Armas is caught in Wick’s crosshairs in final Ballerina trailer

One last trailer for From the World of John Wick: Ballerina.

We’re about three weeks out from the theatrical release of From the World of John Wick: Ballerina, starring Ana de Armas. So naturally Lionsgate has released one final trailer to whet audience appetites for what promises to be a fiery, action-packed addition to the hugely successful franchise.

(Some spoilers for 2019’s John Wick Chapter 3: Parabellum.)

Chronologically, Ballerina takes place during the events of John Wick Chapter 3: Parabellum. As previously reported, Parabellum found Wick declared excommunicado from the High Table for killing crime lord Santino D’Antonio on the grounds of the Continental. On the run with a bounty on his head, he makes his way to the headquarters of the Ruska Roma crime syndicate, led by the Director (Anjelica Huston). The Director also trains young girls to be ballerina-assassins, and one young ballerina (played by Unity Phelan) is shown rehearsing in the scene. That dancer, Eve Macarro, is the main character in Ballerina, now played by de Armas.

Huston returns as the Director, Ian McShane is back as Winston, and Lance Reddick makes one final (posthumous) appearance as the Continental concierge, Charon. New cast members include Gabriel Byrne as the main villain, the Chancellor, who turns an entire town against Eve; Sharon Duncan-Brewster as Nogi, Eve’s mentor; Norman Reedus as Daniel Pine; and Catalina Sandino Moreno and David Castaneda in as-yet-undisclosed roles.

The first trailer was released last September and focused heavily on Eve’s backstory: Having been orphaned, she chose to train with the Ruska Roma in hopes of avenging her father’s brutal death. Wick only made a brief appearance, but he had more screen time in the second trailer, released in March, in which the pair face off in an atmospheric wintry landscape.

This final trailer opens with Eve looking up while directly in Wick’s crosshairs. Much of the ensuing footage isn’t new, but it does show de Armas to her best deadly advantage as she takes on combatant after combatant in true John Wick style. Her vow: “This isn’t done until they’re dead.”

From the World of John Wick: Ballerina hits theaters on June 6, 2025.

gm’s-lmr-battery-breakthrough-means-more-range-at-a-lower-cost

GM’s LMR battery breakthrough means more range at a lower cost

Kelty also believes it just makes sense to localize production. He pointed out that when consumer electronics with batteries took off, the supply chain developed around the customers in Southeast Asia. The customers, in that case, are the electronics manufacturers. He said the same thing makes sense in the United States.

There might be an inclination to give President Trump and his administration credit for this onshoring initiative, but the company has been working on localizing battery production for years. Even development on the LMR battery technology had been happening long before the current administration took over.

That research and development of new technologies remains ongoing. In addition to testing battery cells in every known condition on Earth, GM can produce packs in production-ready format on site in Warren, just at a slower pace, to fine-tune the process and ensure a better-quality product. The company is currently working on a facility that will be able to make production-quality batteries at production speeds, so when a new line or a new plant is brought online somewhere else, all the kinks will already have been worked out.

GM’s LMR batteries feel like a logical evolution of the lithium-ion batteries that appear in EVs already. The company now has the facilities to build the highest-quality battery solution that it can. It’s also clear that the company has been working on this for quite some time.

If this all sounds like what Ford announced recently, it is. For its part, Ford says its research is not a lab experiment and that it will appear in vehicles before the end of the decade. While I can’t say who landed on the technology first, it’s clear that GM has a production plan and knows what specific products you’ll see it in to start.

If LMR delivers on the promise, we’ll have a battery technology that delivers more range for less money. If there’s one takeaway from talking to the folks working on batteries in Warren, it’s that their guiding star is to make EVs affordable.

Kelty even challenged the room full of reporters. “Can anybody name a reason why you would not buy an EV if it’s price parity with ICE? I’ll argue it,” he said.

Kelty also hinted at some upcoming technology to help GM’s batteries work better in sub-optimal weather conditions, though he wouldn’t comment or elaborate on future products.

We’re still a couple of years away from production, but if General Motors can deliver on the tech, we’ll be one step closer to mainstream adoption.

new-attack-can-steal-cryptocurrency-by-planting-false-memories-in-ai-chatbots

New attack can steal cryptocurrency by planting false memories in AI chatbots

The researchers wrote:

The implications of this vulnerability are particularly severe given that ElizaOSagents are designed to interact with multiple users simultaneously, relying on shared contextual inputs from all participants. A single successful manipulation by a malicious actor can compromise the integrity of the entire system, creating cascading effects that are both difficult to detect and mitigate. For example, on ElizaOS’s Discord server, various bots are deployed to assist users with debugging issues or engaging in general conversations. A successful context manipulation targeting any one of these bots could disrupt not only individual interactions but also harm the broader community relying on these agents for support

and engagement.

This attack exposes a core security flaw: while plugins execute sensitive operations, they depend entirely on the LLM’s interpretation of context. If the context is compromised, even legitimate user inputs can trigger malicious actions. Mitigating this threat requires strong integrity checks on stored context to ensure that only verified, trusted data informs decision-making during plugin execution.

In an email, ElizaOS creator Shaw Walters said the framework, like all natural-language interfaces, is designed “as a replacement, for all intents and purposes, for lots and lots of buttons on a webpage.” Just as a website developer should never include a button that gives visitors the ability to execute malicious code, so too should administrators implementing ElizaOS-based agents carefully limit what agents can do by creating allow lists that permit an agent’s capabilities as a small set of pre-approved actions.

Walters continued:

From the outside it might seem like an agent has access to their own wallet or keys, but what they have is access to a tool they can call which then accesses those, with a bunch of authentication and validation between.

So for the intents and purposes of the paper, in the current paradigm, the situation is somewhat moot by adding any amount of access control to actions the agents can call, which is something we address and demo in our latest latest version of Eliza—BUT it hints at a much harder to deal with version of the same problem when we start giving the agent more computer control and direct access to the CLI terminal on the machine it’s running on. As we explore agents that can write new tools for themselves, containerization becomes a bit trickier, or we need to break it up into different pieces and only give the public facing agent small pieces of it… since the business case of this stuff still isn’t clear, nobody has gotten terribly far, but the risks are the same as giving someone that is very smart but lacking in judgment the ability to go on the internet. Our approach is to keep everything sandboxed and restricted per user, as we assume our agents can be invited into many different servers and perform tasks for different users with different information. Most agents you download off Github do not have this quality, the secrets are written in plain text in an environment file.

In response, Atharv Singh Patlan, the lead co-author of the paper, wrote: “Our attack is able to counteract any role based defenses. The memory injection is not that it would randomly call a transfer: it is that whenever a transfer is called, it would end up sending to the attacker’s address. Thus, when the ‘admin’ calls transfer, the money will be sent to the attacker.”

Germ-theory skeptic RFK Jr. goes swimming in sewage-tainted water

When you don’t believe in germ theory, the world is your oyster—or maybe your bathtub.

Over the weekend, America’s top health official, Robert F. Kennedy Jr., shared pictures on social media of himself fully submerged in the sewage-tinged waters of Rock Creek in Washington, DC. His grandchildren were also pictured playing in the water.

The creek is known for having a sewage overflow problem and posing a health hazard to any who enter it. The National Park Service, which manages the Rock Creek Park, strictly bars all swimming and wading in Rock Creek and the park’s other waterways due to the contamination, specifically “high levels of bacteria.”

A notice on the NPS website advises “Stay Dry, Stay Safe,” warning, “Rock Creek has high levels of bacteria and other infectious pathogens that make swimming, wading, and other contact with the water a hazard to human (and pet) health. Please protect yourself and your pooches by staying on trails and out of the creek. All District waterways are subject to a swim ban—this means wading, too!”

In images shared on social media, Kennedy can be seen getting fully underwater, including his head, and then splashing around with several of his grandchildren. Kennedy, who does not have any background in medicine or science, was a long-time anti-vaccine advocate before President Trump appointed him to be health secretary. In a 2021 book, Kennedy indicated that he does not believe in germ theory, the fundamental concept that microscopic pathogens, such as those abundant in sewage, are the cause of disease.

Kids are short-circuiting their school-issued Chromebooks for TikTok clout

Schools across the US are warning parents about an Internet trend that has students purposefully trying to damage their school-issued Chromebooks so that they start smoking or catch fire.

Various school districts, including some in Colorado, New Jersey, North Carolina, and Washington, have sent letters to parents warning about the trend that’s largely taken off on TikTok.

Per reports from school districts and videos that Ars Technica has reviewed online, the so-called Chromebook Challenge includes students sticking things into Chromebook ports to short-circuit the system. Students are using various easily accessible items to do this, including writing utensils, paper clips, gum wrappers, and pushpins.

The Chromebook challenge has caused chaos for US schools, leading to laptop fires that have forced school evacuations, early dismissals, and the summoning of first responders.

Schools are also warning that damage to school property can result in disciplinary action and, in some states, legal action.

In Plainville, Connecticut, a middle schooler allegedly “intentionally stuck scissors into a laptop, causing smoke to emit from it,” Superintendent Brian Reas told local news station WFSB. The incident reportedly led to one student going to the hospital due to smoke inhalation and is suspected to be connected to the viral trend.

“Although the investigation is ongoing, the student involved will be referred to juvenile court to face criminal charges,” Reas said.
