How to perform a reverse phone number lookup

In an age of constant communication, receiving phone calls or messages from unknown numbers has become increasingly common. Whether it's a missed call from an unfamiliar number, a potential scam or a wrong number, performing a reverse phone number lookup can help you identify the caller. You could start your search with free tools like Google or Whitepages, but if you’re struggling to find the person behind the number, paid services such as Spokeo or BeenVerified might give you more detail. In t

Microsoft found a way to let you play YouTube in the background on Android, without Premium

Joe Maring / Android Authority TL;DR Microsoft is testing a new feature on its Edge browser for Android that lets you play videos in the background. The feature can be enabled through the Edge flags page. It works on YouTube, so you can play YouTube videos in the background. Edge Canary for Android also offers a built-in ad blocker that works on YouTube. One of the main benefits of subscribing to the $14 YouTube Premium plan is that it allows you to play videos in the background. But you mig

Poll: Were you affected by Verizon’s service outage over the weekend?

Edgar Cervantes / Android Authority Verizon had a very eventful August, thanks mainly to the unpopular decision to cut loyalty discounts. The company had to resort to damage control by offering new discounts instead of the old ones, but some customers felt tricked into accepting lower discounts. If you were willing to look past all of this, the carrier just bounced back after a rough weekend where it suffered a service outage. Don’t want to miss the best from Android Authority?

Latest Apple Store design combines Genius Bar and Pickup in one counter

A dedicated Pickup counter has been one of the most notable changes in Apple store designs over the last few years, giving a faster service to those customers who have ordered a product for in-store collection. First launched in 2021, the very latest Apple store design has combined this with the Genius Bar in a single counter … Express counters to Pickup Apple’s first iteration of a rapid pickup concept was an Express Counter first launched more than a decade ago. These were stocked with popu

C++: Strongly Happens Before?

Strongly Happens Before? It started innocently enough. I just wanted to brush up on C++ memory orderings. It’s been a while since I last stared into the abyss of std::atomic , so I figured, why not revisit some good ol’ std::memory_order mayhem? Then I saw it. Strongly happens before. Wait, what? When did we get a stronger version of happens before? Turns out, it has been there for quite some time (since C++20 in fact), and it’s actually solving a very real problem in the memory model. If yo

BYD shares slide as China's EV price war hits profits

BYD shares slide as China's EV price war hits profits The Shenzhen-based manufacturer is facing an increasingly crowded market, competing against local rivals Nio and XPeng and US carmaker Tesla, which have all slashed prices to draw buyers. BYD said in its filing that "increased price competition" among China's EV brands had impacted the industry. The carmaker had on Friday reported that its net profit fell to 6.4bn yuan ($900m; £660m) between April and June, down 30% from a year earlier. S

Android 16 has an annoying notification bug, but a fix is coming

Google released the stable version of Android 16 back in June, and it brings some welcome features to the platform. Unfortunately, the update has also introduced a peculiar bug for some. A user posted a report on Google’s Issue Tracker back in June, detailing a strange notification issue in Android 16. More specifically, the user and several others found that notifications don’t play any sounds when there’s already a notification in the notification shade. “When testing notifications, we reali

Mainframe upgrade done with wire cutters (2010)

Post by h***@bbs.cpcn.com IBM obviously "lost money" in giving out free software; I don't think they charged even for distribution tapes or documentation even in the 1970s after unbundling; if it was a legacy free item, you got the package for free. (And IIRC, some unbundled fee products were still quite cheap, esp as compared to today's software prices.) Anyway, the free software was IBM's 'loss leader' to build the utility value of its computers. IBM unbundled this partly in response to

Lewis and Clark marked their trail with laxatives

Audio version is not yet available By Finn J.D. John January 26, 2025 AS LEWIS AND CLARK’S Corps of Discovery made its way across the continent to Oregon, the men (and woman) of the party probably weren’t thinking much about their place in history. So they weren’t taking any particular pains to document their every movement. There were, however, some particular pains they were experiencing with every movement, so to speak ... as a result of a relentlessly low-fiber diet: Everyone was constip

“This telegram must be closely paraphrased before being communicated to anyone”

It appears that it was US military communications doctrine to not send the exact same message twice using different encryption ("none" counting as one type of encryption), and the term of art for changing a message to avoid that was indeed "paraphrase". I managed to dig up a US Army document on Cryptology from roughly that era that appears to discuss paraphrasing. The document in question is Department of the Army Technical Manual TM 32-220(pdf), dated 1950, titled "BASIC CRYPTOGRAPHY". It appa

Murder at Burning Man turns Silicon Valley’s desert playground into a crime scene

A homicide investigation has rocked the final days of Burning Man after a man was found dead “lying in a pool of blood” Saturday night at the Nevada desert festival, according to the Pershing County Sheriff’s Office. According to the New York Times, the grim discovery occurred around 9:14 p.m. just as the festival’s iconic wooden “Man” effigy began its traditional burn. The victim, described as a white adult male whose identity remains unknown, was found by a festival participant who flagged do

Meet the Top 10 AI-Proof Jobs That Everyone Wants

AI is rapidly scaling in the workforce and creating fears of an employment crisis, as workers and people entering the workforce try to figure out if their career is on the chopping block. That quick pace is backed by emerging data. As a result, people are trying to find “AI-proof” jobs that can guarantee job security as companies around the world choose to automate tasks instead of hiring new workers. Although no study can definitively say which occupations are 100% AI-proof and which are doom

UK age check law seems to be hurting sites that comply, helping those that don’t

In Brief The United Kingdom recently started enforcing the Online Safety Act’s age-check rules, and The Washington Post reports that it’s already having a significant effect on web traffic. U.K. law now requires pornography websites to verify their users’ ages through means such as face scans and driver’s licenses; it also requires that online platforms prevent children from being exposed to adult content (which is why sites like Bluesky and Reddit have begun checking some users’ ages). To st

A Single Typo in Your Medical Records Can Make Your AI Doctor Go Dangerously Haywire

A single typo, formatting error, or slang word makes an AI more likely to tell a patient they're not sick or don't need to seek medical care. That's what MIT researchers found in a June study currently awaiting peer review, which we covered previously. Even the presence of colorful or emotional language, they discovered, was enough to throw off the AI's medical advice. Now, in a new interview with the Boston Globe, study coauthor Marzyeh Ghassemi is warning about the serious harm this could ca

This smart pointer is used to share references to the same underlaying pointer.

A 20-Year-Old Algorithm Can Help Us Understand Transformer Embeddings

Suppose we ask an LLM: “Can you tell me about Java?” What “Java” is the model thinking about? The programming language or the Indonesian island? To answer this question, we can try to understand what is going on inside the model. Specifically, we want to represent the model’s internal states in a human-interpretable way by finding the concepts that the model is thinking about. One approach to this problem is to phrase it as a dictionary learning problem, in which we try to decompose complex emb

Verizon Finally Restores Service in Most Areas After Day-Long Outage

Verizon said thousands of people who were affected nationwide by a massive outage now have service back. If your Verizon-backed phone was out most of yesterday or even still down today, you weren’t alone. The company said the blackout was caused by a “software issue” but did not respond to a request to elaborate on what exactly that meant. Verizon officials assured customers that their engineers were actively engaged in diagnosing and resolving the service disruption. By early evening, the com

$1B Powerball Is Minting Social Media Gold

Powerball just hit a billion dollars, and people are freaking out about it. For 39 draws in a row, no ticket matched all six numbers for the Powerball jackpot. The last draw was on Saturday night. Now, for the next drawing on Labor Day, the jackpot has snowballed to $1.1 billion and will be the game’s fifth-largest prize ever, according to a statement from the lottery. The largest jackpot prize ever was cashed out in November 2022 by Edwin Castro, a California man who scored a $2.04 billion do

iOS 26 Beta Brings AI Summaries Back to News Apps, but With a Warning

Apple released the fifth public beta of iOS 26 on Aug. 25, and the beta brings a new Liquid Glass design to the iPhones of developers and beta testers, alongside other updates such as call screening. And developers and beta testers with an Apple Intelligence-enabled iPhone will see AI notification summaries for news and entertainment apps in the latest beta. Apple disabled AI notification summaries for news and entertainment apps in January. That came a few weeks after the BBC pointed out in De

I'm a Runner with Over 15 Years of Running Experience. These Are the Best Treadmills of 2025

The first thing I noticed about the NordicTrack Commercial 2450, NordicTrack's newest addition to its commercial treadmill series, is the touchscreen. It has a 22-inch HD touchscreen that resembles a desktop computer screen, so it's huge. It also tilts and pivots so you can adjust it for different uses, like if you want to take workout classes on the floor. The treadmill itself is also on the bigger side since it's a commercial treadmill, but it does fold up using its easylift assist feature, so

Earth models can predict the planet’s future but not their own

In the 1960s, meteorologist Edward Lorenz was running weather simulations on an early computer system when he realized that a small rounding difference led to extremely divergent weather predictions. He later called this idea the butterfly effect to communicate that small changes in initial conditions, like a butterfly flapping its wings in Nepal, could produce wildly different outcomes, like rain in New York. But better understanding those initial conditions and how the biological world couple

Extreme Heat Makes Your Body Age Faster

It is well known that heat causes exhaustion in the body due to dehydration. But aging? A recent study concluded that extreme heat accelerates the aging of the human body, a worrying fact given the increasing frequency of heat waves due to climate change. The researchers are not talking about the effects of solar radiation on the skin, but biological aging. Unlike chronological age—that answer that you give when asked how old you are—your biological age reflects how well your cells, tissues, a

Daily Hub is one of the worst Pixel features I’ve ever used

Joe Maring / Android Authority One of my favorite reasons for using a Google Pixel phone is the incredible suite of Pixel-exclusive software features. Whether it’s Now Playing automatically identifying songs or using the numerous Call Assist tools to make phone calls less of a headache, it’s these features that make using a Pixel so special. Google has ushered in a load of additional software tricks with the Pixel 10 series, one of them being Daily Hub. Daily Hub is supposed to be a one-stop s
