The startup behind open source tool Polars raises $21M from Accel

Polars, the Amsterdam-based company behind the popular open source project of the same name, has raised €18 million (about $21 million) in a Series A round led by Accel, with participation from Bain Capital Partners and angel investors. But while raising this kind of money is the dream of many developers, its creator Ritchie Vink didn’t set out to do so. It all started as a pet project during Covid. Frustrated with the limitations of Pandas, a tool for organizing and working with data tables, V

Your iPhone's Maps App Is Tracking You in iOS 26. Here's How to Stop It

Apple released iOS 26 on Sept. 15, and the update brought Liquid Glass, call and text screening, and more hidden features to your iPhone. It also gave your Maps app a new feature called Visited Places that can track where you go, but you can turn the feature off in Settings. The feature was on by default after I updated my device to iOS 26, and it was detecting and logging places I visit, like restaurants, shops and parks. It could be useful if you want to remember a restaurant you went to a fe

Can Vibration Plates Help You Lose Weight? Fitness Experts Reply

A vibration plate may seem like a fun, modern piece of exercise equipment, and many claim that the full-body vibrations it provides can help you get stronger while losing weight. But is this too good to be true? Are vibration plates a type of workout we should all try? To find the potential benefits and risks associated with vibration plates, along with who should avoid them and which exercises are best on vibration plates, we reached out to fitness experts to answer all of your questions. Don'

The AI services transformation may be harder than VCs think

Venture capitalists have convinced themselves they’ve found the next big investing edge: using AI to wring software-like margins out of traditionally labor-intensive services businesses. The strategy involves acquiring mature professional services firms, implementing AI to automate tasks, then using the improved cash flow to roll up more companies. Leading the charge is General Catalyst (GC), which has dedicated $1.5 billion of its latest fundraise to what it calls a “creation” strategy that’s

Pick up this battery-powered Ring doorbell while it's down to $80 ahead of Prime Day

If you've been considering a video doorbell for your front door, Prime Day deals may have just what you're looking for at a good price. A great deal already available is on the latest Ring Battery Doorbell Plus, which is 47 percent off and down to only $80. The Battery Doorbell Plus offers a 150-by-150-degree "head to toe" field of vision and 1536p high-resolution video. This makes it a lot easier to see boxes dropped off at your front door since it doesn't cut off the bottom of the image like

Akira ransomware breaching MFA-protected SonicWall VPN accounts

Ongoing Akira ransomware attacks targeting SonicWall SSL VPN devices continue to evolve, with the threat actors found to be successfully authenticating despite OTP MFA being enabled on accounts. Researchers suspect this may through the use of previously stolen OTP seeds, though the exact method remains unconfirmed at this time. In July, BleepingComputer reported that the Akira ransomware operation was exploiting SonicWall SSL VPN devices to breach corporate networks, leading researchers to susp

A look at OpenAI's tangled web of dealmaking

OpenAI CEO Sam Altman speaks to media following a Q&A at the OpenAI data center in Abilene, Texas, U.S., Sept. 23, 2025. Shelby Tauber | Reuters While OpenAI says that scaling is key to driving innovation and future AI breakthroughs, investors and analysts are beginning to raise their eyebrows over the mindboggling sums, as well as OpenAI's reliance on an increasingly interconnected web of infrastructure partners. OpenAI took a $350 million stake in CoreWeave ahead of its IPO in March, for inst

Delivery Robot Torments Disabled Man

A man with cerebral palsy who uses a mobility scooter to travel experienced a blood-boiling episode when he kept getting cut off — by a robot. In a video that’s gone viral on social media, Mark Chaney repeatedly attempts to drive his scooter around a sluggish delivery bot operated by a startup called Swerve Robotics as it randomly stops and occupies half a sidewalk in West Hollywood. Even more strangely, the clanker courier — like certain maniac drivers on a highway — seemed to get swept into

AI Coding Is Massively Overhyped, Report Finds

The AI industry has made major promises about its tech boosting the productivity of developers, allowing them to generate copious amounts of code with simple text prompts. But those claims appear to be massively overblown, as The Register reports, with researchers finding that productivity gains are modest at best — and at worst, that AI can actually slow down human developers. In a new report, management consultants Bain & Company found that despite being “one of the first areas to deploy gen

My life would be a mess without these 8 productivity apps

Andy Walker / Android Authority We all have a daily productivity workflow, whether carefully honed after wild experimentation or naturally formulated through habit. Mine sits in the middle of these two poles. I’ve been on an ongoing mission to streamline my digital life, especially regarding the digital tools and apps I use daily. After years of testing various products and processes, I’ve realized I gravitate toward the same 8 productivity apps. Here’s how I use each of them. Do you use a pro

‘GoldenEye’ is Coming Back to Theaters Next Week

We’re not getting a new James Bond movie for a while, but at least we can see an old one in theaters pretty soon. On Friday, October 3, GoldenEye will play in select theaters worldwide, and exclusively at Alama Drafthouse for U.S. audiences. The re-release serves two purposes: first, October 5 is James Bond Day—Dr. No, the first film in the series premiered on that day in 1962—and GoldenEye itself will turn 30 years old in November. (Beyond the deisgnated holiday, its October date may also be d

Trump posts, then pulls bizarre AI video promoting MedBed conspiracy

Donald Trump is no stranger to outlandish conspiracies or strange social media posts. But, by any measure, his post on Saturday night was particularly bizarre. The president posted (and later removed) a clip on Truth Social of a Fox News segment with Lara Trump detailing the White House’s announcement of the world’s first MedBed hospital and a national MedBed card system (two things that very much do not exist). There was no additional context, no text to explain things. Confusing matters more,

I compared Apple Visual Intelligence to Circle to Search, and the winner won’t surprise you

Ryan Haines / Android Authority I might be that annoying friend — the one who always wants to fact-check something. I’m not usually trying to be obnoxious, I just want to make sure I’m getting the correct information, especially when things are so easily faked right now (sorry, it’s true). Honestly, I’ve always been this way, and I think it started with a heavy reliance on Google Lens. Seriously, though, I used Google’s camera-based identifier for everything. Unfamiliar shoes? Google Lens. Wei

6 crucial features the new Google Home app needs to win me back

Rita El Khoury / Android Authority Google is working on a brand new Home app with Gemini integration. My colleague AssembleDebug was able to trigger that new interface and showed off the spiffy redesign with streamlined tabs that merge favorites and devices under a new Home tab, and push settings up to the account switcher. There’s a permanent new “Ask Home” text box at the top to talk to your smart home via Gemini, ask about security camera activity and device statuses, execute actions, or eve

Big Google Home app redesign with ‘Ask Home’ starts rolling out on iPhone

We previously spotted that the Google Home app was getting a redesign with “Ask Home” and it’s now beginning to roll out for iPhone users ahead of the October 1 announcement. The company curiously released version 4.0.54 of Google Home for iOS on Saturday afternoon (PT). This introduces a more rounded icon with a gradient color palette, like the Google G and Gemini. After swiping away the app and relaunching, we’re seeing a big redesign (we’re in the Public Preview program). On initial launch,

Google Messages is rethinking how link previews work, but we’re not sure it’s for the best

Edgar Cervantes / Android Authority TL;DR Google devs appear to be considering implementing some changes to how Messages displays link previews. Previews could drop the full URL, and might start omitting page descriptions. Messages may start coloring its previews to match page graphics. What do you think about before clicking on a link? Are you the sort of user who scrutinizes the URL, looking for any info that may help clarify what sort of content awaits on the other end? Do you just blindl

WWE’s Drew McIntyre Will Be Henry Cavill’s ‘Highlander’ Brother

The upcoming Highlander movie will be a family affair, as wrestler Drew McIntyre has joined the film as Henry Cavill’s brother. Per Deadline, the two-time WWE champion will play Angus MacLeod, brother to Cavill’s Connor. In the original movie, Angus was played by James Cosmo; he’s one of Connor’s cousins featured in flashbacks to the 16th-century Scottish Highlands. After Connor died and experienced his first Quickening, Angus was the only one who didn’t reject him outright and ordered their cl

'One Battle After Another' Is a Film You Really Should Go See in a Theater

One Battle After Another hit theaters on Friday. Paul Thomas Anderson's 10th film, and the first that takes place in the present day since Punch Drunk Love (which came out in 2002), is a whallop of a movie. It's an unpredictable roller-coaster ride that tackles some tough subject matter, yet it isn't a tough pill to swallow. If you ask me (and you're the one reading this, so you are), it's probably my favorite movie of the year. If it were up to me, you'd see One Battle After Another on the big

You Can Now Get 3D Printed Shoes and We Can Never Go Back

You may not have your own 3D printer but I guarantee that you know someone who does. With an estimated industry worth of $100 billion by 2030, 3D printing is a growing trend that can only become more mainstream over time. Helping with that trend is the emergence of 3D printed apparel that people actually want to use, including 3D printed shoes that even the best 3D printers you have at home can't reproduce. In collaboration with Zellerfeld, a leading shoe manufacturer, the team behind the 3D P

Experts Alarmed That AI Is Now Producing Functional Viruses

AI can now invent working biological viruses. In real world experiments, a team of Stanford researchers demonstrated that a virus with AI-written DNA could target and kill specific bacteria, they announced in a study last week. It opened up a world of possibilities where artificial viruses could be used to cure diseases and fight infections. But experts say it also opened a Pandora’s box. Bad actors could just as easily use AI to crank out novel bioweapons, keeping doctors and governments on t

Android’s answer to Apple’s Handoff is coming, and here’s how it’ll work

Mishaal Rahman / Android Authority One area where iOS beats Android is its deep integration with MacBooks, which is to be expected since Apple controls both ecosystems. While tools exist to connect your Android phone to a Windows PC, these solutions often fall short of Apple’s integrations. This gap exists because Android and Windows are developed by different companies with competing interests, which complicates the creation of native, deeply integrated features. For example, Apple’s Handoff

Fundamental of Virtual Memory

Fundamental of Virtual Memory Contents What and Why? Have you ever wondered why computers need main memory (RAM) when they already have disk storage? The answer lies in access speed. While disk storage is permanent, it is much slower than main memory. RAM sacrifices volatility for speed—data is lost when the power is off, but access times are much faster. As a result, the CPU can only access data from main memory, not disk storage. CPUs come with built-in registers, which are even faster tha

Reinventing SETI: Why Our Alien-Hunting Playbook Needs an Upgrade

Editor’s note: The following is an excerpt from Reinventing SETI: New Directions in the Search for Extraterrestrial Intelligence, published by Oxford University Press in August 2025. John Gertz is the president and CEO of Zorro Productions, Inc., and a former chairman of the board of the SETI Institute. In his book, Gertz argues that humanity should rethink the search for intelligent life by rejecting outdated paradigms like the Drake Equation, the Fermi Paradox, and the idea of actively broadca

NASA Couldn’t Get Its Rover to the Moon, So Blue Origin Will Do It Instead

NASA’s water-hunting lunar rover was given a second chance to reach the surface of the Moon. Blue Origin will deliver VIPER to the Moon on an upcoming lunar lander mission, resurrecting the exploration mission after it was called off last year. NASA contracted Blue Origin to transport its lunar rover to the Moon as part of the agency’s Commercial Lunar Payload Services. The Volatiles Investigating Polar Exploration Rover, or VIPER, was originally set to launch in 2023 but faced several delays u
