An anonymous reader quotes a report from Ars Technica: Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet. The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.

To bypass the bottleneck, companies are turning to Merkle Trees, a data structure that uses cryptographic hashes and other math to verify the contents of large amounts of information using a small fraction of material used in more traditional verification processes in public key infrastructure. Merkle Tree Certificates, “replace the heavy, serialized chain of signatures found in traditional PKI with compact Merkle Tree proofs,” members of Google’s Chrome Secure Web and Networking Team wrote Friday. “In this model, a Certification Authority (CA) signs a single ‘Tree Head’ representing potentially millions of certificates, and the ‘certificate’ sent to the browser is merely a lightweight proof of inclusion in that tree.”

[…] Google is [also] adding cryptographic material from quantum-resistant algorithms such as ML-DSA (PDF). This addition would allow forgeries only if an attacker were to break both classical and post-quantum encryption. The new regime is part of what Google is calling the quantum-resistant root store, which will complement the Chrome Root Store the company formed in 2022. The [Merkle Tree Certificates] MTCs use Merkle Trees to provide quantum-resistant assurances that a certificate has been published without having to add most of the lengthy keys and hashes. Using other techniques to reduce the data sizes, the MTCs will be roughly the same 64-byte length they are now […]. The new system has already been implemented in Chrome.

Welcome to our latest roundup of what’s going on in the indie game space. It’s Steam Next Fest week, with literally thousands of demos for upcoming games for us to dive into. I’m trying to check out as many as I can before the event wraps up on Monday. However, I made a near-critical error in my planning: I opted to try the Raccoin demo first. I could and would have happily played that all week.

This is a coin-pushing roguelike deckbuilder that adopts the format of Balatro. To progress, you need to earn a certain number of points and the target increases each round. Every three rounds there’s a sort-of boss — a few coins that negatively impact your game until you can get rid of them. After every round, you’ll go to a shop to buy and sell special coins and other upgrades. As you might expect with this type of game, finding ways to boost the points you can score from each coin is how to win.

On my first successful run, I found a way to electrify the coins (which boosts their score) by charging them and use passive abilities and special coins to spread and amplify the effect. Then I was able to replicate a special coin that pulls all other nearby coins into a cyclone — having the water-based coins in there helped to spread the electrical effect between other coins. There were a few rounds in which I didn’t even have to do anything. The cyclones just dumped enough coins over the edge for me. 

This was only the first way I’ve figured out how to break the game. Six hours in, I’m eager to find many more.

Raccoin — from Doraccoon and Balatro publisher Playstack — will hit Steam on March 31. The demo is currently still available.

I’ve had The Eternal Life of Goldman on my wishlist since we first learned about it a couple of years ago. I’m very glad that was one of the demos I’ve tried. This is an utterly gorgeous platform adventure with hand-drawn art. As Goldman, an elderly gentleman, you’ll swap parts of your cane on the fly so you can hook onto floating rings or pogo off springs. 

The platforming is challenging enough that I had to focus to get through the demo, which lasts about 75-90 minutes. There’s almost always something going on in the background or foreground too. This game from Weappy Studio is shaping up to be quite something. I can’t wait to play the full thing when The Eternal Life of Goldman hits PC, Nintendo Switch, PS5 and Xbox Series X/S, hopefully later this year.

Of course I had to check out the Next Fest demo for Vampire Crawlers, which is also available on Xbox. The latest game from Poncle is a turn-based deckbuilder roguelite. Oh, and it’s also a Vampire Survivors spin-off. Instead of passively firing your weapons at surrounding enemies, you have a bit more control here. 

It plays a bit like those first-person maze games from the ’90s. You’ll walk around each level with the help of a map that shows where enemies, chests and bosses are located. When you encounter enemies, you’ll play cards in a certain order to deal damage or boost your stats for that particular battle. You can play all your available cards in one go, but you might want to rearrange them first so that you, for instance, use a card that boosts your damage before firing any weapons. Each card has a mana point value — you can only play a full hand if you have enough mana. And yes, there are weapon evolutions.

Turn-based games usually aren’t my bag, but sometimes they just hit right. The Vampire Crawlers demo hits right. I can already tell I’m going to spend dozens of hours with the full game, which is coming to Steam, Xbox Series X/S, PS5, Nintendo Switch, iOS and Android this year. 

I tried a few other demos so far, including one for John Carpenter’s Toxic Commando, a co-op shooter in the vein of Left 4 Dead. It’s a little rough around the edges right now, but it seems enjoyable enough. 

There are a bunch of other Next Fest demos I’m hoping to try over the weekend, including precision platformer Croak, PvE pirate game Windrose, cyberpunk platformer Replaced, record store sim Wax Heads, match-three/tower-defense game Titanium Court and Dragon Care Tarot. I read that you can pet dragons in the latter, so I’m sold.

New releases

If you can’t get enough of The Witcher and are impatiently waiting for CD Projekt Red to unleash The Witcher IV, here’s one way to keep your thumbs busy in the meantime. Reigns: The Witcher is the latest installment of the Reigns series from Nerial and Devolver Digital for Steam, Android and iOS ($6). 

You still play as Geralt of Rivia. However, this is a narrative-focused game in which you make choices by swiping. It’s something a little different for Witcher fans. It might just pull some long-time Reigns players into that fantasy universe for the first time too.

Bread and Fred is the cutest thing. The co-op platformer from SandCastles Studio has been available on PC (Steam, GOG and Epic Games Store) and Nintendo Switch for a while, and this week it landed on Xbox One, Xbox Series X/S, PS4 and PS5. It normally costs $15 and there’s a 20 percent launch discount on those consoles. You’ll need to be a PS Plus subscriber to get those savings on PlayStation, though.

You and a friend take control of a pair of adorable penguins that are tethered together. The aim is to ascend a mountain, sometimes by swinging each other to get to hard-to-reach places. But if you miss a jump, you can plummet back down and erase a chunk of your progress. There is a single-player mode in which one of the penguins is replaced by a rock. The pixel art aesthetic here is super charming.

Here’s another co-op game. This one is a side‑scrolling RPG brawler. After several months in early access/game preview, the full version of Stoic’s Towerborne arrived on Xbox Series X/S, Xbox on PC, Steam and PS5. It costs $25, though there’s a 20 percent launch discount on Xbox. It’s on Game Pass Ultimate and Premium as well. 

After the 1.0 update, the game has a full campaign that you can play offline by yourself or online with friends. Stoic has added fresh biomes, enemies and bosses, and there are said to be hundreds of missions, side quests and bounties. I really dig the fluidity of the animations in the trailer, though the action is a bit hard to parse at first glance. Still, I’m curious enough to try out Towerborne.

I’ve been a little too occupied with other Next Fest demos (plus Overwatch challenges, I’ll admit it) to play Dice A Million yet, but this roguelike deckbuilder looks pretty interesting. The aim is to find the right combination of dice and rings (i.e. passive abilities) to roll a million points in one go. As with the likes of Balatro, it’s all about figuring out powerful synergies between dice and rings to break the game and rack up ridiculous scores. I did quite enjoy a line on the Steam page that reads, “Cutting edge next-gen graphics (not really, I drew all of them on paint).”

Dice A Million — from Countlessnights and publisher 2 Left Thumbs — is also available on Itch and Xbox on PC. It’s on Game Pass Ultimate and PC Game Pass. Otherwise, it costs $13, but there’s a 20 percent discount on Steam until March 11. There’s a demo available on Steam too.

Upcoming 

Let’s start this section with a news roundup. Mouse: P.I. for Hire continues to look rad, but unfortunately we’ll have to wait a little longer to play it. Fumi Games and publisher PlaySide have delayed it by a few weeks until April 16 to polish the game up.

I do love voxel-based heist game Teardown, so I’m jazzed for the online multiplayer update. Tuxedo Labs revealed it will go live on Steam on March 12.

It will add a co-op campaign option (for up to 12 players!). There’ll be hundreds of other multiplayer modes created by the studio and the community, including prop hunt, battle royale and floor-is-lava modes. There’s going to be so much carnage. The PS5 and Xbox Series X/S versions of Teardown will get the multiplayer update later this year.

ConcernedApe (aka Eric Barrone) marked the 10-year anniversary of Stardew Valley by showing off some very early gameplay footage, some stories from his time of working on his all-time-great indie game and revealing the two additional characters that players will be able to marry when the 1.7 update goes live. Sandy’s cool, so it’ll be nice to have her as an option, but Clint? That guy sucks. Here’s hoping Barrone will finally focus more of his attention on Haunted Chocolatier once this Stardew update is done and dusted.

Also as part of the 10th anniversary celebrations, it was revealed this week that an orchestra will deliver a one-night-only performance of music from Stardew Valley at the Red Rocks Amphitheatre in Colorado on October 25. I missed my chance to see the Symphony of Seasons tour in person when it stopped near me, because I don’t always make the wisest decisions in life. At least we can now watch an official recording of a previous concert.

Minimap, a social platform for gamers, ran its first indie game showcase this week. Among the highlights:

• Thrifty Business (Spellgarden Games), a cozy thrift-store management sim that’s coming to Steam this year. A demo’s available now.

• Another look at Please, Watch The Artwork, an anomaly-spotting game — without jump scares or monsters — from Please, Touch The Artwork developer Thomas Waterzooi.

• Lily’s World XD, a psychological horror game from SonderingEmily in which you’ll investigate a teenage girl’s laptop in the early 2000s. The trailer brings to mind screenlife films like Searching and Unfriended.

• Coming-of-age adventure Ikuma – The Frozen Compass from Mooneye Studios. You’ll play as both cabin boy Sam and husky Ellie (or have a friend take control of one of them) as you try to make your way home from the Arctic. This should hit Steam later this year. 

Tombwater was originally supposed to arrive in November, but Moth Atlas and publisher Midwest Games delayed it for further refinement. It’s now set to arrive on Steam on March 31.A Next Fest demo is available now.

This is a 2D Soulslike with a Western setting and 2D pixel art that’s inspired by Bloodborne and early Legend of Zelda games. You’ll face off against horrific eldritch creatures as you search for a missing friend. You’ll have seven playable classes to choose from and the ability to wield more than 50 firearms and melee weapons, and more than 20 spells. Tombwater is said to have around 20 hours of gameplay.

There’s no release date for Solarpunk as yet, but I found this trailer quite soothing. It offers a first look at co-op gameplay for this base-building and exploration game from the two-person team at Cyberwave and publisher rokaplay. 

Up to four players will be able to explore floating islands, gather resources and build out a homestead together. As the title suggests, there’s a technology-driven element to Solarpunk. You can use renewable energy sources to power tools that can automate things like resource harvesting and watering plants. The airships you use to travel between islands look cool too.

Solarpunk is set to hit Steam later this year. A demo is available now.

On February 24th, the Vera C. Rubin Observatory activated its automated alert system, sending out roughly 800,000 real-time notifications flagging asteroids, supernovae, flaring black holes and “other transient celestial events,” reports Scientific American. And this is only the beginning — that number is projected to climb into the millions as it continues scanning the ever-changing sky. From the report: The astronomical observatory equipped with world’s largest camera hit a key milestone on February 24, when a complex data-processing system pushed hundreds of thousands of alerts out to scientists eager to pore over its most exciting sightings. The Vera C. Rubin Observatory began operations last year, capturing stunning, panoramic time-lapse views of the cosmos with ease. Rubin’s first images, based on just 10 hours of observations, let space fans zoom seemingly forever into an overwhelmingly starry sky. But watchful astronomers were always awaiting the next step: the system that would automatically alert them to the most promising activity in the overhead sky amid the 1,000 or so enormous images that Rubin’s telescope captures every night.

“We can detect everything that changes, moves and appears,” said Yusra AlSayyad, an astronomer at Princeton University and Rubin’s deputy associate director for data management, to Scientific American last summer. “It’s way too much for one person to manually sift through and filter and monitor themselves.” So even as they were designing and building the Rubin Observatory itself, scientists were also designing an alert system to help astronomers navigate the flood of data. As soon as the telescope began observations, the team started constructing a static reference image of the entire sky in impeccable detail.

Now the data processing systems that support the observatory are starting to automatically compare every new Rubin image to the corresponding section of that background template. The systems identify all of the differences, each of which is individually flagged. The algorithms can also distinguish between a potential supernova and a possible newfound asteroid, for example. Alerting the scientific community is the final, crucial step. Astronomers — as well as members of the public — can sign up for notifications based on the type of sighting they’re interested in and the brightness of the observation in question. And now that the alerts system has gone live, users receive a tiny, fuzzy image with some astronomical metadata of each observation that fits their criteria — all just a couple of minutes after Rubin captures the original image.

Southern California’s air quality board rejected proposed rules to phase out gas-powered appliances after receiving more than 20,000 opposition comments generated through CiviClick, “the first and best AI-powered grassroots advocacy platform.” Phys.org reports: A Southern California-based public affairs consultant, Matt Klink, has taken credit for using CiviClick to wage the opposition campaign, including in a sponsored article on the website Campaigns and Elections. The campaign “left the staff of the Southern California Air Quality Management District (SCAQMD) reeling,” the article says. It is not clear how AI was deployed in the campaign, and officials at CiviClick did not respond to repeated requests for comment. But their website boasts several tools, including “state of the art technology and artificial intelligence message assistance” that can be used to create custom advocacy letters, as opposed to repetitive form letters or petitions often used in similar campaigns.

When staffers at the air district reached out to a small sample of people to verify their comments, at least three said they had not written to the agency and were not aware of any such messages, records show. But the email onslaught almost certainly influenced the board’s June decision, according to agency insiders, who noted that the number of public comments typically submitted on agenda items can be counted on one hand.

The proposed rules were nearly two years in the making and would have placed a fee on natural gas-powered water heaters and furnaces, favoring electric ones, in an effort to reduce air pollution in the district, which includes Orange County and large swaths of Los Angeles, Riverside and San Bernardino counties. Gas appliances emit nitrogen oxides, or NOx — key pollutants for forming smog. The implications are troubling, experts said, and go beyond the use of natural gas furnaces and heaters in the second-largest metropolitan area in the country.

OpenAI has reached an agreement with the Defense Department to deploy its models in the agency’s network, company chief Sam Altman has revealed on X. In his post, he said two of OpenAI’s most important safety principles are “prohibitions on domestic mass surveillance and human responsibility for the use of force, including for autonomous weapon systems.” Altman claimed the company put those principles in its agreement with the agency, which he called by the government’s preferred name of Department of War (DoW), and that it had agreed to honor them.

The agency has closed the deal with OpenAI, shortly after President Donald Trump ordered all government agencies to stop using Claude and any other Anthropic services. If you’ll recall, the government US Defense Secretary Pete Hegseth previously threatened to label Anthropic “supply chain risk” if it continues refusing to remove the guardrails on its AI, which are preventing the technology to be used for mass surveillance against Americans and in fully autonomous weapons. It’s unclear why the government agreed to team up with OpenAI if its models also have the same guardrails, but Altman said it’s asking the government to offer the same terms to all the AI companies it works with.

Anthropic, which started working with the US government in 2024, refused to bow down to Hegseth. In its latest statement, published just hours before Altman announced OpenAI’s deal, it repeated its stance. “No amount of intimidation or punishment from the Department of War will change our position on mass domestic surveillance or fully autonomous weapons,” Anthropic wrote. “We will challenge any supply chain risk designation in court.”

Altman added in his post on X that OpenAI will build technical safeguards to ensure the company’s models behave as they should, claiming that’s also what the DoW wanted. It’s sending engineers to work with the agency to “ensure [its models’] safety,” and it will only deploy on cloud networks. As The New York Times notes, OpenAI is not yet on Amazon cloud, which the government uses. But that could change soon, as company has also just announced forming a partnership with Amazon to run its models on Amazon Web Services (AWS) for enterprise customers.

An anonymous reader quotes a report from Wired: OpenAI has fired an employee following an investigation into their activity on prediction market platforms including Polymarket, WIRED has learned. OpenAI CEO of Applications, Fidji Simo, disclosed the termination in an internal message to employees earlier this year. The employee, she said, “used confidential OpenAI information in connection with external prediction markets (e.g. Polymarket).” “Our policies prohibit employees from using confidential OpenAI information for personal gain, including in prediction markets,” says spokesperson Kayla Wood. OpenAI has not revealed the name of the employee or the specifics of their trades.

Evidence suggests that this was not an isolated event. Polymarket runs on the Polygon blockchain network, so its trading ledger is pseudonymous but traceable. According to an analysis by the financial data platform Unusual Whales, there have been clusters of activities, which the service flagged as suspicious, around OpenAI-themed events since March 2023. Unusual Whales flagged 77 positions in 60 wallet addresses as suspected insider trades, looking at the age of the account, trading history, and significance of investment, among other factors. Suspicious trades hinged on the release dates of products like Sora, GPT-5, and the ChatGPT Browser, as well as CEO Sam Altman’s employment status. In November 2023, two days after Altman was dramatically ousted from the company, a new wallet placed a significant bet that he would return, netting over $16,000 in profits. The account never placed another bet.

The behavior fits into patterns typical of insider trades. “The tell is the clustering. In the 40 hours before OpenAI launched its browser, 13 brand-new wallets with zero trading history appeared on the site for the first time to collectively bet $309,486 on the right outcome,” says Unusual Whales CEO Matt Saincome. “When you see that many fresh wallets making the same bet at the same time, it raises a real question about whether the secret is getting out.” […] Though this is the first confirmed case of a large technology company firing an employee over trades in prediction markets, it’s almost certainly not the last. Opportunities for tech sector employees to make trades on markets abound. “The data tells me this is happening all over the place,” Saincome says.

Researchers at Cortical Labs used living human neurons grown on a chip to learn how to play Doom in about a week. “While its performance is not up to par with humans, experts say it brings biological computers a step closer to useful real-world applications, like controlling robot arms,” reports New Scientist. From the report: In 2021, the Australian company Cortical Labs used its neuron-powered computer chips to play Pong. The chips consisted of clumps of more than 800,000 living brain cells grown on top of microelectrode arrays that can both send and receive electrical signals. Researchers had to carefully train the chips to control the paddles on either side of the screen. Now, Cortical Labs has developed an interface that makes it easier to program these chips using the popular programming language Python. An independent developer, Sean Cole, then used Python to teach the chips to play Doom, which he did in around a week.

“Unlike the Pong work that we did a few years ago, which represented years of painstaking scientific effort, this demonstration has been done in a matter of days by someone who previously had relatively little expertise working directly with biology,” says Brett Kagan of Cortical Labs. “It’s this accessibility and this flexibility that makes it truly exciting.”

The neuronal computer chip, which used about a quarter as many neurons as the Pong demonstration, played Doom better than a randomly firing player, but far below the performance of the best human players. However, it learnt much faster than traditional, silicon-based machine learning systems and should be able to improve its performance with newer learning algorithms, says Kagan. However, it’s not useful to compare the chips with human brains, he says. “Yes, it’s alive, and yes, it’s biological, but really what it is being used as is a material that can process information in very special ways that we can’t recreate in silicon.” Cortical Labs posted a YouTube video showing its CL1 biological computer running Doom. There’s also source code available on GitHub, with additional details in a README file.

The bigger they come, the slower they move

“The bigger you make the certificate, the slower the handshake and the more people you leave behind,” said Bas Westerbaan, principal research engineer at Cloudflare, which is partnering with Google on the transition. “Our problem is we don’t want to leave people behind in this transition.” Speaking to Ars, he said that people will likely disable the new encryption if it slows their browsing. He added that the massive size increase can also degrade “middle boxes,” which sit between browsers and the final site.

Comments

joshuark shares a report from Ars Technica: Perplexity has introduced “Computer,” a new tool that allows users to assign tasks and see them carried out by a system that coordinates multiple agents running various models. The company claims that Computer, currently available to Perplexity Max subscribers, is “a system that creates and executes entire workflows” and “capable of running for hours or even months.”

The idea is that the user describes a specific outcome — something like “plan and execute a local digital marketing campaign for my restaurant” or “build me an Android app that helps me do a specific kind of research for my job.” Computer then ideates subtasks and assigns them to multiple agents as needed, running the models Perplexity deems best for those tasks. The core reasoning engine currently runs Anthropic’s Claude Opus 4.6, while Gemini is used for deep research, Nano Banana for image generation, Veo 3.1 for video production, Grok for lightweight tasks where speed is a consideration, and ChatGPT 5.2 for “long-context recall and wide search.”

This kind of best-model-for-the-task approach differs from some competing products like Claude Cowork, which only uses Anthropic’s models. All this happens in the cloud, with prebuilt integrations. “Every task runs in an isolated compute environment with access to a real filesystem, a real browser, and real tool integrations,” Perplexity says. The idea is partly that this workflow was what some power users were already doing, and this aims to make that possible for a wider range of people who don’t want to deal with all that setup.

People were already using multiple models and tailoring them to specific tasks based on perceived capabilities, while, for example, using MCP (Model Context Protocol) to give those models access to data and applications on their local machines. Perplexity Computer takes a different approach, but the goal is the same: have AI agents running tailor-picked models to perform tasks involving your own files, services, and applications. Then there is OpenClaw, which you could perceive as the immediate predecessor to this concept.
