In linear algebra, scalars play the role of coefficients, scaling factors, and e
Mishaal Rahman / Android Authority TL;DR Gboard’s AI-powered Writing Tools feature, which debuted on the Pixel 10, is now rolling out to some non-Pixel devices. Powered by the on-device Gemini Nano model, the feature helps users proofread and rephrase text directly within the keyboard.

We’re just one week away from Apple unveiling its flagship iPhone 17 lineup, and while market analysts have generally been expecting price increases on most new models, the latest report indicates we might be in for good news.

Declan would never have found out his therapist was using ChatGPT had it not been for a technical mishap. The connection was patchy during one of their online sessions, so Declan suggested they turn off their video feeds. Instead, his therapist began inadvertently sharing his screen. For the rest of the session, Declan was privy to a real-time stream of ChatGPT analysis rippling across his therapist’s screen, who was taking what Declan was saying, putting it into ChatGPT, and then parroting i
It seems clear we’re still a year away from the first iPhone Fold, but the rest of the market isn’t standing still. Samsung is planning to launch its first trifold phone this year, and Huawei is already onto its second-generation model. On a pedantic note, I would argue that as they have two sets of hinges, they are bifold rather than trifold, but the industry seems to have adopted the latter term, so I guess we’re stuck with it now … Huawei was first off the block with the Mate XT, shown abov

By Colin on 2025-08-30 "But I need types," he told me. Humans have a tendency toward binary thinking (pardon the pun). If it's not A, it's B. Perhaps because Lisps have REPLs, they are often thought of from the outside as being dynamic, interpreted languages. Our years of Python have taught us that such languages don't really have strong typing - it's all a wild guess until the interpreter calls foo on a and b and we find out who everyone really is. Yet Common Lisp is fully typed, and AOT com

Last week was the first time I picked up Final Fantasy Tactics since finishing it back in 1998. One infamous boss battle scarred me so badly that I never went back -- and given its reputation among fans, I know I'm not alone. So when I had the chance to talk with Kazutoyo Maehiro, part of the original dev team and now director of the upcoming remaster, Final Fantasy Tactics: Ivalice Chronicles, I jumped at it. I needed to know why they made that one fight so brutal. My question for Maehiro: "Ba
Porsche provided flights from Albany to Barcelona and accommodation so Ars could drive a prototype Cayenne Electric. Ars does not accept paid editorial content. Curved displays in cars are increasingly common, adding a bit of shape to the increasing pixel overload we face behind the steering wheel. The designers of Porsche's upcoming Cayenne Electric, though, decided to do something more dramatic with the touchscreen that commands the center of the forthcoming SUV's dashboard. Its shape flows

I’ve seen a lot of influences for wireless audio products (single-use pill packaging and cassette tapes, for example), but JBL’s Grip is a first. According to JBL, the Grip, a new smallish Bluetooth speaker announced at IFA 2025 that focuses on portability, is modeled after the proportions of a seltzer can. To be honest, my first thought was a tallboy, but maybe that says more about me than it does JBL. No matter what you think of when you see the Grip, it sounds like a solid Bluetooth speaker
Lanh Nguyen / Android Authority TL;DR Samsung started the One UI 8 beta for the Galaxy S23 yesterday.

Marcin Wichary December 2023 / 8,000 words / 33 photos The primitive tortureboard Untangling the myths and mysteries of Dvorak and QWERTY This essay was originally published in December 2023 as sixth chapter of the book Shift Happens. 1 There weren’t many who hated QWERTY more. To his credit, there was a lot to hate. The layout seemed random, with letters strewn around without rhyme or reason. Watching someone type on it felt painful: fingers flailed wildly all over the place, common letter
At this summer's HOPE conference, Joshua Aaron spoke about ICEBlock, his iPhone app that allows users to anonymously report ICE sightings within a 5 mile radius, and to get notifications when others report ICE sightings near them. You can see the full talk, and the lively/infuriating Q&A, here, starting at 6:12:10. Thanks to repression from the highest levels of the Trump administration, his app has gone viral and garnered over a million downloads from the App Store. Karoline Leavitt called it

And this year, Home Depot's infamous giant skeleton returns with an app that gives the new Ultra Skelly a voice and fresh moves to spook trick-or-treaters. Make no bones about it: Skelly's going high tech. The new animatronic version is shorter than the original, at 6.5 feet tall, but you can freak out your whole neighborhood with this skeleton's rotating upper torso, mo
What is Ripple? Currently, this project is still in early development, and should not be used in production. Ripple is a TypeScript UI framework that takes the best parts of React, Solid and Svelte and combined them into one package.

But the reality is much more fascinating and convoluted. The transition was meandering and lengthy, and
