5G promised a revolution, but here’s what we actually got

Robert Triggs / Android Authority Depending on where you live, you’ve likely had 5G in your pocket for at least a couple of years — or possibly close to half a decade. In any case, the wireless tech has certainly been around long enough to have had time to accomplish the numerous lofty promises that CEOs piped up to upsell us, which included everything from rejuvenating retail to traffic lights pushing updates to your car. While some of those promises might have come to pass, quite a lot of th

Choosing the rijght .NET container image for your workload

All the .NET Core Opsy Things Part 1: Choosing the right .NET core Image for your workload Bill 7 min read · 3 days ago 3 days ago -- Listen Share This guide began as a conversation between me and someone exploring how to containerize .NET apps. The same questions kept coming up; from new developers to infrastructure and DevOps engineers and I kept pointing people to the docs. I decided to turn it into a practical walk through and post it here for anyone who finds it useful. When you pull an

Physicists Create First-Ever Antimatter Qubit, Making the Quantum World Even Weirder

Readers following our existential physics coverage may remember a recent breakthrough from CERN concerning matter’s evil twin, antimatter. An outstanding mystery in physics is that our universe contains more matter than antimatter, contradicting most theoretical predictions. Scientists, therefore, understandably want to explain why and how this is the case. CERN announced yet another significant leap for studying antimatter—and this time, the achievement creeps into the realm of quantum computi

Monotonic and wall clock time in the Go time package

Monotonic and Wall Clock Time in the Go time package Modern operating systems usually keep track of two kinds of clocks: a wall clock and a monotonic clock. The wall clock is the “real-world” clock that shows calendar dates and times, like UTC or your local time. This clock can be adjusted for synchronization (for example, using NTP) or manually changed by system administrators. It can also suddenly jump due to daylight saving time or leap seconds. Note NTP (Network Time Protocol) is a standa

Tesla's Optimus Robots Have Reportedly Run Into Severe Trouble

Elon Musk's Tesla is in deep trouble. This week, the company reported a massive 16 percent decline in automotive revenues, the biggest drop in over a decade. With tax incentives and auto regulatory credits being phased out by president Donald Trump, Musk conceded that the company is facing a "few rough quarters" ahead. While Musk didn't manage to reassure investors about rescuing Tesla's car sales business — the company's shares plummeted following Wednesday's earnings call — the billionaire i

Bluetti’s small, camp-friendly generator is over 30 percent off

We’re in the middle of prime camping season, when the days are longer and the temperatures are warmer. While it’s the perfect time to unplug, you don’t have to go completely off the grid, as Bluetti’s AC2P Portable Power Station can power your essential gadgets when no traditional power sources are available. And right now, the power station is on sale at Amazon (with an on-page coupon), Walmart, and Lowe’s for around $169 ($80 off), matching the all-time low we saw during Prime Day. If you pla

Tesla is reportedly behind on its pledge to build 5,000 Optimus bots this year

In Brief Tesla is well behind the pace needed to meet its earlier stated goal of producing at least 5,000 Optimus humanoid robots this year, The Information reports. Nearly eight months into 2025, and the number of bots Tesla has produced is only in the hundreds, according to two sources. That means Tesla will either need to step it up or push back the deadline. The news comes after Tesla reported a 12% decline in overall revenue in the second quarter, due to falling EV sales, less cash from r

When photography was born, fascination, obsession, and danger followed

The prevalence of photography in contemporary life has inspired a lot of griping about the supposedly unprecedented narcissism of our social-media-driven culture. We are continually encouraged to live in the moment instead of through our cameras, scolded for our pursuit of a flattering selfie or an aesthetic backdrop that will draw eyes — and engagement — to our photos and ourselves. But this obsession is nothing new. From nearly the first moment it became possible to capture an image from life

Earth’s Unusual Rapid Spin Could Prompt First-Ever ‘Negative Leap Second’

The Earth has been spinning unusually fast recently. Last year on July 4, our planet set a record by completing a full spin 1.66 milliseconds (0.00166 seconds) faster than usual, according to timeanddate.com. One year later, on July 10, 2025, Earth completed a daily rotation that scientists estimate was 1.36 milliseconds faster than usual, giving us another particularly short day. Other shorter (but ever-so-slightly longer) days occurred on July 9 and July 22, although the exact margins have yet

Somnee Smart Sleep Headband Review: High-Tech Help

I have struggled with insomnia for as long as I can remember. I’ve tried basically every sleep aid on the market, plus I need a sound machine, sleep mask, blackout curtain, and weighted blanket to even begin the process of trying to fall asleep. So I decided to try something new. Before bed, on and off for the past several months, I've been wearing Somnee, a wearable sleep tech headband that aims to map the brain using EEG (electroencephalogram) sensors to deliver individualized therapeutic sti

This $50 Electric Toothbrush Replaced My Stolen $200 One Without a Hitch

CNET's key takeaways The $50 Oral-B Pro 1000 Electric Toothbrush works just as well as my previous $200 toothbrush. The Pro 1000 has three modes, a 2-minute brushing timer and a pressure sensor. Though it doesn't come with an app or more smart features, I enjoy its simplicity. The last time I visited a friend in San Francisco, a thief broke into their car and stole my luggage. Inside it, I had my precious $200 electric toothbrush, which I'd reviewed at a previous job and didn't have to pay f

The FDA Is Using an AI to "Speed Up" Drug Approvals and Insiders Say It's Making Horrible Mistakes

Image by Getty / Futurism Developments Insiders at the Food and Drug Administration are ringing alarm bells over the agency's use of an AI to fast-track drug approvals. As CNN reports, six current and former FDA officials are warning that the AI, dubbed Elsa, which was unveiled weeks earlier, is "hallucinating" completely made-up studies. It's a terrifying reality that could, in a worst-case scenario, lead to potentially dangerous drugs mistakenly getting the stamp of approval from the FDA.

I Underestimated Workout Buddy. Apple's Playing the Long Game for AI Coaching

I didn't think I needed a "buddy" to cheer me on during a workout when Apple first announced its new Workout Buddy feature in WatchOS 26. Despite it being an AI-powered voice that extols you with positive feedback as you run (or as you do any number of activities), I was envisioning a non-nonsense trainer that would push me out of my comfort zone and into peak performance. But after testing it myself and talking in-depth with Apple about how it works, I'm starting to think the company undersold

Apple solves its social media fragmentation problem with ‘In the Loop’

Social media has been fragmented since Twitter got X’d and cleared the path for Threads, Bluesky, Mastodon, and others. Still, Apple personalities like Tim Cook still rely on sharing company news, often exclusively, on X. Others seem more fond of Instagram. It’s a lot to follow, especially if you’re off one or more social media networks. Apple seems to have heard the feedback that it can be rather strange that company news, especially from CEO Tim Cook, can solely exist somewhere like X. The f

$1 billion of NVIDIA AI chips were reportedly sold in China despite US bans

Financial Times is reporting that $1 billion worth of NVIDIA AI chips were smuggled into China in the three months after the Trump administration tightened semiconductor export controls . Citing sales contracts, company documents and people with direct knowledge, the publication says that a thriving black market arose for American semiconductors. Products sold included NVIDIA's top‑tier B200 chips, which have become the silicon of choice for American big tech when training AI models. Sale of the

Writing is thinking

Writing scientific articles is an integral part of the scientific method and common practice to communicate research findings. However, writing is not only about reporting results; it also provides a tool to uncover new thoughts and ideas. Writing compels us to think — not in the chaotic, non-linear way our minds typically wander, but in a structured, intentional manner. By writing it down, we can sort years of research, data and analysis into an actual story, thereby identifying our main messag

Sony is finally making it possible to pair a DualSense with more than one device

Sony is bringing a welcome quality-of-life feature to the PlayStation 5. In the next PS5 system update beta, players will be able to have their DualSense controllers synced with multiple hardware platforms at the same time. That means you could swap a controller from a PS5 to your gaming PC to your smartphone without needing to re-pair the DualSense each time. Up to four devices can be simultaneously paired with a single controller, and each of them will be mapped to one of the action buttons.

Using uninitialized memory for fun and profit (2008)

Using Uninitialized Memory for Fun and Profit Posted on Friday, March 14, 2008. This is the story of a clever trick that's been around for at least 35 years, in which array values can be left uninitialized and then read during normal operations, yet the code behaves correctly no matter what garbage is sitting in the array. Like the best programming tricks, this one is the right tool for the job in certain situations. The sleaziness of uninitialized data access is offset by performance improveme

Optimizations That Aren't

Optimizations that aren't We all like it when our code is fast. Some of us like the result, but dislike the process of optimization; others enjoy the process. However, optimization for the sake of optimization is wrong, unless you’re doing it in your pet project. Optimized code is sometimes less readable and, consequently, harder to understand and modify; because of that, optimization often introduces subtle bugs. Since optimization is not a process with only positive effects, in production it

I'm Unsatisfied with Easing Functions

I'm unsatisfied with easing functions You've probably encountered easing functions before. If you're a creative coder, you've likely heard of them or used them. If you're a user, you've certainly interacted with them. They're everywhere, and they give a little more life to computer generated animations. Taking it easy For the uninitiated: let's say you've got a circle that you want to move from left to right over the course of a second. We can conceptualize this by converting the time into pr

I continue to use Google Home and its speakers, but I hate everything about it

I’ve been in the Google Home camp since the first speaker launched in November of 2016, though you might even say that I started earlier, with the first Chromecast in 2013. Since then, I’ve had a couple of Lenovo Smart Displays, some JBL Link speakers, the JBL Link View, the Google Home Mini, Nest Audio, Nest Hub, and many others that are too esoteric to remember. Today, my home houses two Nest Audios, a Pixel Tablet, and a Nest Hub, scattered across three floors, and even though I’m at the end

‘Marvel Rivals’ Will Let You Recreate the ‘Fantastic Four: First Steps’ Dive Bomb

Ask anyone what the Thing’s catchphrase is, and, almost certainly, everyone will simultaneously say, “It’s clobbering time!” That’s just been a fact of the character for years. And, in the new movie Fantastic Four: First Steps, it’s also the case, but with a little twist. A twist that’s coming to the video game Marvel Rivals in a kind of unprecedented synergy of gameplay and movie promotion. As seen in a recent trailer for First Steps, “It’s clobbering time!” is the in-universe catchphrase of t
