If there’s one thing that we’ve learned in the world of mixed reality over the past year, it’s that price is pretty much everything. Just ask Apple, which is still struggling to find an audience for its $3,500 Vision Pro headset. I mean, it’s not that there’s not a lot to love about the Vision Pro (the best UI in mixed reality and a premium display are particular highlights), but I bought my first used car for a price that wasn’t too far off, and that at least got me to work semi-on time. It’s
September is gearing up to be one of the most exciting months of the year for new technology launches, with Meta reportedly set to unveil its next-generation smart glasses. Codenamed Hypernova, according to Bloomberg, the glasses are set to start around $800 for the basic model -- that's at least $200 less than previously thought. This pair of glasses will reportedly differ from the current Meta Ray-Bans due to the addition of a small augmented-reality display in the right lens of the glasses,
Update, 8/17/2025 @ 10:57 AM: After his old Twitter posts were discovered, Bloodshot writer Mauro Mantella has since deleted the account and posted an apology on Instagram. “I want to offer my most sincere apologies. I know I made a mistake, but at no point did I intend to spread a message of hate,” it begins. In his apology, he revealed he first wrote the issue’s script in Spanish, then “changed it a bit” when converting it to English. This conversion led to him “borrowing a common phrase used
Stellar death is a complex and mysterious process — but in the case of a supernova known as 2023zkd, things were more gruesome than any astronomer had ever seen before. As its name suggests, this supernova — the fabulous astronomical term for the explosive death of a star — was first spotted back in 2023, when Southern California's Zwicky Transient Facility zeroed in on it thanks to new AI algorithms designed to detect such brilliant blasts. This supernova, however, was different. It appeared,

C. Scott Brown / Android Authority TL;DR Meta’s first augmented reality glasses are reportedly launching next month. These glasses, codenamed “Hypernova,” will offer a barebones interface with basic support for notifications and Meta’s AI. The glasses are reported to launch at just $800, to rake in far more orders than Apple’s extravagantly priced Vision Pro. Apple took a leap of faith when it first showcased its $3,500 extended reality headset, the Vision Pro, in 2023. Despite the slow roll

We just shipped a new feature in NextDNS: Bypass Age Verification. More and more sites (especially adult ones) are now forcing users to upload IDs or selfies to continue. We think that’s a terrible idea: handing over government documents to random sites is a huge privacy risk. This new setting workarounds those verification flows via DNS tricks. It’s available today to all users, including free accounts. We’re curious how the HN community feels about this. Is it the right way to protect priva

Innovation at the End of the Valve Era The development of the Nuvistor in the late-1950s was probably the last major innovation in receiving valve technology, coming as it did towards the end of the era of thermionic device domination. Transistors at that time weren't the full answer to all problems in electronics, and so valves still had a lot to offer. The Nuvistor is often regarded as a last desperate effort by valve manufacturers to stem the flow of 'transistorisation' which was becoming a

This article explains how these four things fit together and shows some examples of what they are used for. Derivatives Derivatives are the most fundamental concept in calculus. If you have a function, a derivative tells you how much that function changes at each point. If we start with the function , we can calculate the derivative as . Here are those two functions graphed. One use of derivatives is for optimization – also known as finding the lowest part on a graph. If you were at and wan
Most VPN providers offer a VPN app for Mac computers, but it can be difficult to choose the right provider with so many options available. Based on our extensive research and hands-on testing of VPNs over the years, these are the most important factors to consider when choosing a VPN: Privacy The primary consideration for any VPN -- including a Mac VPN -- should be privacy. If your Mac VPN is unable to sufficiently protect your online privacy, then your VPN is useless. At a minimum, your VPN s

Lisp in 99 lines of C and how to write one yourself In honor of the contributions made by Church and McCarthy, I wrote this project and the accompanying article to show how anyone can write a tiny Lisp interpreter in a few lines of C or in any "C-like" programming language for that matter. I attempted to preserve the original meaning and flavor of Lisp as much as possible. As a result, the C code in this project is strongly Lisp-like in compact form. Despite being small, these tiny Lisp interpr
This story originally appeared on Grist and is part of the Climate Desk collaboration. Diplomats from around the world concluded nine days of talks in Geneva—plus a marathon overnight session that lasted into the early hours of Friday—with no agreement on a global plastics treaty. During a closing plenary that started on Friday at 6:30 am, more than 15 hours after it was originally scheduled to begin, nearly all countries opposed an updated draft of the United Nations treaty that was put forwa

There's a new smartphone promising to protect your privacy: the Up Phone, from a company called Unplugged. Except it's not new. Unplugged has been around for a few years—the company was cofounded by Erik Prince, the founder of private military company Blackwater—and it originally announced the Up Phone in 2023. But this week, the company claims it's “relaunching” the phone, under new leadership. Like the original, the Up Phone's UnpluggedOS (formerly LibertOS) is built on the Android Open Sourc

Edgar Cervantes / Android Authority TL;DR RCS support has opened the door for some advanced messaging features, and earlier this year Google started work on a new remote-deletion option. Users are able to delete recently sent messages from the phones of recipients. After beta testing this past spring, we’re now seeing the feature widely available. Who doesn’t love a good do-over? Everybody makes mistakes, and we don’t have nearly enough opportunities to go back and try setting things right.

iOS 18.4 finally brought robot vacuum support to HomeKit, opening the door for a new wave of Matter-enabled vacuums that work with your existing smart home environment. I’ve been testing the Ecovacs Deebot X8 Pro Omni for the past few months (even before iOS 18.4) to see how well it fits into a smart home, but more importantly, whether it’s worth the money as a way to keep your floors cleaned. Some of my favorite gear Abode Home Security System Abode is the best home security system and include
A couple of years ago, a curious, then-16-year-old hacker named Reynaldo Vasquez-Garcia was on his laptop at his Portland-area high school, seeing what computer systems he could connect to via the Wi-Fi—“using the school network as a lab,” as he puts it—when he spotted a handful of mysterious devices with the identifier “IPVideo Corporation.” After a closer look and some googling, Garcia figured out that a company by that name was a subsidiary of Motorola, and the devices he’d found in his scho
