Just because a game is on disc doesn’t mean it will work in the future

Just because a game is on disc doesn’t mean it will work in the future

Sony’s recent decision to stop producing physical PlayStation games in the near future has naturally led to a renewed focus and appreciation for physical games that can be played just by sticking a cartridge or disc in a console. But an increasing number of those “physical” games these days still require additional downloads from a centralized server to function as intended.

For years now, the testers at DoesItPlay have been documenting this trend, testing thousands of physical game releases to see which ones live up to the promise of full “plug and play” functionality without an Internet connection. Thus far, a full 27 percent of the physical releases they’ve tested require some sort of download to fix game-breaking bugs or obtain core game content that is not stored on the physical release itself. That ratio balloons to 34 percent for tested PS5 games and 50 percent for those on the Xbox Series X.

“There is a clear trend that physical releases are increasingly treated with ignorance from larger companies,” DoesItPlay owner and head admin Clemens Itsel told Ars recently. “There is no reason physical games would ever die unless someone like Sony deliberately kills them.”

Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission

Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission

fivenewscrypto    juillet 31, 2026   

A quantum-resistant cryptography algorithm that was under consideration as an official US standard has been taken out of the running after an Anthropic security model helped find a flaw that rendered it broken.

The algorithm is known as HAWK. It's a digital signature scheme designed to withstand future attacks from quantum computers. HAWK had survived two rounds of testing by NIST (the National Institute of Standards and Technology) for evaluating the security of PQC (post-quantum cryptographic) algorithms through widespread testing. HAWK was in a third round of testing designed to catch precisely the kinds of flaws Mythos helped uncover.

Following Anthropic's Monday announcement of the results, the developer of HAWK said Tuesday he was withdrawing it.

Google's "privacy-preserving" age verification system is coming to the Play Store

Google's "privacy-preserving" age verification system is coming to the Play Store

fivenewscrypto    juillet 31, 2026   

Governments around the world are suddenly very keen on online age verification requirements. In some places, this takes the form of ID requirements to access adult content, but several US states have also focused on app stores. With these laws now going into effect, Google has announced an expansion of its beta Play Age Signals API, which it claims will allow developers to confirm user ages without impinging on privacy.

Google's system doesn't require an ID or selfie verification—it's connected to the company's existing Family Link app. The idea is that parents will set age ranges for their kids' managed accounts. For example, you might set a range like 16–17, allowing apps to tailor experiences and content for teenagers.

Google notes that the ranges are dynamic and may change as young users get older. So a kid who's 13 may be in the same app content bracket for a few years before hitting the next level. Parents have the option to set and share these ranges if they want that additional level of control over what their children can access in Google Play. However, it's not mandatory for child accounts—it's fully opt-in and can be turned off at any time.

Elon Musk’s xAI is trying to sue its way out of a Grok reckoning

Elon Musk’s xAI is trying to sue its way out of a Grok reckoning

fivenewscrypto    juillet 31, 2026   

Elon Musk’s xAI is trying to sue its way out of a Grok reckoning as arrests of Grok users accused of making child sex abuse materials (CSAM) have triggered lawsuits from kids to sue xAI to force changes to the tool to block harmful outputs.

Earlier this month, xAI started suing users who are allegedly circumventing its safeguards to generate AI CSAM, seemingly hopeful that an early court win will guarantee it’s not liable for supposedly user-generated content.

For its next move, the Grok maker pointed to that lawsuit in a complaint filed Monday, accusing Minnesota of trying to force changes to Grok and Grok Imagine by enforcing a ban on nudification technology that would guarantee that xAI was liable for the harmful outputs, as well as outputs that allegedly weren’t sexualizing people without consent. According to xAI, suing a Grok user is proof that xAI is already doing everything in its power to punish bad actors, and therefore, Grok deserves safe harbor from Minnesota’s ban.

Yet more qubit tech: New quantum dot options, diamond vacancies

Yet more qubit tech: New quantum dot options, diamond vacancies

fivenewscrypto    juillet 30, 2026   

If you follow quantum computing news for long enough, it can start to seem like any quantum system that can alternate between two well-separated energy states can be used as a qubit. Atoms, ions, photons, electrons, and manufactured devices all have their backers. One of the key things that attracts backers is the tech's ability to scale. We'll need a lot of high-quality qubits to start doing any complex computations, and the ability of any technology to get us there is the subject of debate.

So even as some technologies can now support thousands of qubits, some competitors are still working on a small handful of qubits—the companies behind them are convinced that they have the potential to scale more effectively.

One of those technologies involves quantum dots that hold a single electron. Their advantage is that we can manufacture them using the same tech we use to build traditional processors, an approach that has proven to be scalable. This week saw two new papers describing different ways of using quantum dots, one of which was appealing enough that IBM bought the company that developed it. Separately, another company has released a processor showing 100 individual electrons being held in diamond defects, technology that wasn't obvious could scale.

Actually, Starliner might fly into space this year

Actually, Starliner might fly into space this year

fivenewscrypto    juillet 30, 2026   

When we last checked in on Boeing's Starliner spacecraft in February, NASA was announcing that it had formally classified the 2024 crewed flight of the Starliner spacecraft as a “Type A” mishap, an acknowledgement that the test flight was a serious failure.

At the time, NASA Administrator Jared Isaacman said the space agency was working with Boeing to "fully understand the risks associated" with the Starliner spacecraft, and to remediate them. Starliner would not fly its next mission, a cargo flight to the International Space Station, until those problems were identified and remediated. He declined to put a date on the test flight.

However, it now appears this work is proceeding apace.

Anthropic is finding bugs faster than Microsoft can fix them

Anthropic is finding bugs faster than Microsoft can fix them

fivenewscrypto    juillet 30, 2026   

On an afternoon in mid-May, dozens of Microsoft engineers and their managers gathered online and in a conference room at the company’s Redmond, Washington, headquarters to discuss Project Glasswing.

The tech giant was racing to fix weaknesses in its code that a new AI model known as Mythos was uncovering at an unprecedented clip. The AI behemoth Anthropic, which developed Mythos, had given access to select organizations that make software used by regular people, companies, and governments across the world. The goal was to find and fix the vulnerabilities before hackers and adversarial governments like China began using similar tools to find and exploit them for espionage and sabotage.

As the group settled in, one engineer asked the question that loomed over the meeting: Did Mythos “live up to the hype that Anthropic claimed it would have had?”
