Nostr

There are many problems with Mastodon, mostly due to the fact that it doesn't rely on any cryptography. Because it cannot do the multi-master approach of Nostr due to lack of cryptography, identities are assumed to be "owned" by the server, which is fully trusted by its tenants. Mastodon server owners can do all the harm centralized platforms can do to their underlings, which are completely helpless in case of misbehavior or even in the normal case where a server owner loses their server or deci

Meta Ray-Ban Display hands-on: Discreet and intuitive

I've been testing smart glasses for almost a decade. And in that time, one of the questions I've been asked the most is "oh, but can you see anything in them?" For years, I had to explain that no, glasses like that don't really exist yet. That's no longer the case. And while I've seen a bunch of glasses over the last year that have some kind of display, the Meta Ray-Ban Display glasses feel the closest to fulfilling what so many people envision when they hear the words "smart glasses." To be c

The Land Bridge You’ve Never Heard Of

For many of us, when we think of land bridges, we tend to think of the Bering Land Bridge (actually more of a swamp), which ancient humans traversed to reach North America from modern-day Siberia during the last Ice Age. But there may have been another, crucial stretch of land that aided early human migration—this time, far across the continent, on the Anatolian coast. That’s the major new finding from a team of Turkish archeologists who have uncovered over 100 stone artifacts from ten differen

Meta Ray-Ban (1st Gen) vs. Ray-Ban (2nd Gen): I compared both smart glasses, and there's a clear winner

Jason Hiner/ZDNET Follow ZDNET: Add us as a preferred source on Google.

Mark Zuckerberg Humiliated as AI Glasses Debut Fails in Front of Huge Crowd

On Wednesday, Meta CEO Mark Zuckerberg unveiled a slew of new augmented reality glasses, including what he claimed to be the "first AI glasses with high resolution," a new $799 version of its Meta Ray-Ban smart glasses that features a tiny screen that's viewable to the wearer. But it didn't take long for the company's MetaConnect 2025 keynote to descend into chaos. The social media giant's demos repeatedly failed, leading to awkward stares, deafening silences, and muted laughter. The poor show

iPhone 18 Pro might fix iPhone 17 Pro’s most polarizing design choice

iPhone 18 Pro rumors have already started, including one that says Apple may be changing the most polarizing design element of iPhone 17 Pro: the glass cutout on the back of the device. Rear glass cutout design might be changing with iPhone 18 Pro Apple made some bold design changes with this year’s iPhone lineup.

Federico Viticci’s in-depth iOS 26 review: ‘A new era for Apple’s software’

It’s been a busy week in the Apple world, between reviews of new iPhones and the release of iOS 26. One of the highlights of new iOS season every year is Federico Viticci’s in-depth review at MacStories. Given the vast nature of iOS 26 and iPadOS 26 this year, I was even more excited than usual to read his review. Here’s Federico on Liquid Glass: In the past three months, I’ve realized that Liquid Glass – beyond simply looking gorgeous on modern Apple hardware – is more than meets the eye. Su

Meta will let outside developers create AI-powered apps for its smart glasses

Meta's lineup of smart glasses could soon get a lot more capabilities. The company will begin allowing outside developers to bring their apps to its RayBan and Oakley smart glasses, Meta announced on the second day of its Connect event. Up to now, Meta has only had a limited number of third-party integrations for its glasses, with apps like Spotify and Audible. But Meta will now allow developers to start experimenting with apps that can take advantage of the built-in sensors and audio capabilit

Something Extremely Strange Is Happening at the Event Horizon of This Supermassive Black Hole

In 2019, scientists unveiled the first-ever images of a black hole, M87*. Those observations kickstarted a wave of new investigations into how black holes work, how they grow, and how they change. And now, after a few upgrades, the Event Horizon Telescope network is back with another bombshell centered on M87*—finding tantalizing evidence of previously unknown physics at the event horizon of the black hole itself. In a series of images taken by the EHT between 2017 and 2021, scientists observed

Tesla's Robotaxis Have Already Gotten Into Numerous Accidents

Tesla has been caught hiding details of three separate robotaxi accidents that happened since the launch of the service. As Electrek reports, the Elon Musk-led company reported the three crashes, which occurred in the early days of its pilot robotaxi service in Austin, to the National Highway Traffic Safety Administration (NHTSA.) At the time, the company's robotaxi fleet of modified Model Y vehicles only consisted of "ten to 20" vehicles, according to Musk, which even had safety drivers sitti

Struggling to find the right app for the job? Google Play’s new tool has some ideas for you

Edgar Cervantes / Android Authority TL;DR Google Play Store is rolling out an AI-powered app explorer in the US. It suggests categories like “Boost productivity” or “Protect my privacy” directly in the search tab. Selecting one opens an “Organized with AI” section grouping related apps by type. Finding the right app in the Google Play Store can sometimes feel like looking for a needle in a haystack, but AI can actually be handy for this sort of thing. Google is now testing a new Gemini-power

Users are annoyed by this Google Phone change, but it may be working as intended

Alex Walker-Todd / Android Authority TL;DR Google’s Phone app has historically forced a portrait orientation while making calls. Users have recently noticed that this no longer holds true, and some devices set to auto-rotate will turn even in calls. We’re not seeing this behavior consistently across devices, and it’s unclear if it’s truly intended. The vast majority of your smartphone usage probably takes place in portrait mode, ideal for one-handed operation. When we’re turning our phones f

Meta product chief Chris Cox says smart glasses are the future of computing

Meta Chief Product Officer Chris Cox said on Thursday that smart glasses are the future of computing devices. "We talk to them, we will see with them, we will use gestures the same way we interact with each other to interact with our computers," Cox told CNBC's Julia Boorstin. "The interfaces will get more natural, and so we certainly believe that the next really important wearable technology is going to be a pair of glasses." The $799 Meta Ray-Ban Display glasses, which were revealed on Wedne

Mysterious Object From Beyond Solar System May Be "Seed" Traveling Galaxy and Creating New Planets, Paper Finds

Astronomers have been fascinated after spotting an object earlier this year that came from interstellar space as is now hurtling through our inner solar system. Since then, they've been using powerful telescopes to study the mysterious object, trying to understand its unusual composition and exact origins. Most agree that it's probably a comet, albeit an unusual one, though at least one has posited that it could be a remnant of an advanced extraterrestrial civilization — a colorful claim, but o

Tesla is looking to redesign its door handles following trapped-passenger report

Tesla is looking into redesigning the way to open its car doors in an emergency followingï»ż several accidents where passengers were reportedly trapped in burning vehicles because rescuers could not open them. Even without an accident, other Tesla owners have reported having to break their own car windows after buckling their children in and then being unable to get in the car again, according to an investigation launched by the National Highway Traffic Safety Administration, citing owner complai

Configuration files are user interfaces

18 Sep, 2025 We have all been there. Your software keeps growing and you feel the need to make it customizable. It is too soon for a full-blown UI with all the bells and whistles, so your pragmatic instinct suggests a text-based configuration file. Yes, that’s exactly it! You rejoice knowing the software’s configuration will be trivial to version control. Your pragmatic instinct is satisfied as well; the door remains open to creating a proper UI later, since it would be merely a graphical view

Satya Nadella is haunted at the prospect of Microsoft not surviving the AI era

“Some of the biggest businesses we’ve built might not be as relevant going forward,” admitted Microsoft CEO Satya Nadella during an employee-only town hall last week. Nadella was responding to a question about the perceived change in culture inside Microsoft, but his answer revealed a lot more about his own fears over Microsoft’s future in this AI era. “Our industry is full of case studies of companies that were great once, that just disappeared. I’m haunted by one particular one called DEC,” s

DACLab says it can remove CO2 using less electricity than many competitors

The world’s countries may have pledged to cut its carbon pollution, but with global emissions reaching an all-time high last year they’ve fallen far short. Digging out of that hole is going to require removing carbon straight from the atmosphere. But it comes with a hefty price tag, mostly because of the energy required. Removing one metric ton of CO 2 using direct air capture is expected to require around 2,000 kWh of electricity when the technology is sorted and scaled up. One startup called

American Prairie unlocks another 70k acres in Montana

Public lands and public access are now constantly under threat in the U.S., but there’s still good news to share. Ambitious conservation nonprofit American Prairie has secured its second-largest land purchase and leasing arrangement to date, buying up the 70,000-acre Anchor Ranch in Montana, which had been listed for sale for $35 million. The group bought the land from two billionaire Texas brothers who’d kept the public locked out of one of the only western access roads into adjacent public la

NASA Mission to Map Sun’s Protective Bubble Could Help Better Predict Dangerous Space Weather

The Sun is an energetic star, constantly radiating energy and pumping streams of charged particles out into space. And while this solar wind can be dangerous in itself, without it, Earth and all the other members of our planetary system would be at constant risk of threats from outer space. Our host star creates a protective bubble called the heliosphere that extends far beyond the orbit of Neptune, shielding the planets from the interstellar medium. Yet though we may owe our existence to this b

Samsung’s very expensive Family Hub fridges will now treat you to ads on their displays

If you’ve just shelled out thousands of dollars on one of Samsung’s smart fridges , you’d be forgiven for expecting it to leave you alone, rather than encouraging you to spend even more money. But that is no longer the case — following a recent update, you’ll start seeing ads on the fridge’s display. According to Android Authority , the new software update is being rolled out to Samsung’s Family Hub refrigerators in the US, and will now display ads and promotions while the display is idle. In a
