The unbearable sameness of Liquid Glass

Liquid Glass is a neat party trick. The new design system, which was built for nearly all of Apple’s products and is rolling out this week, is built on the idea that interfaces should be three-dimensional: in the world of Liquid Glass, buttons and menus sit on top of whatever you’re doing or looking at, changing color and refracting digital light like they’re physical objects. It’s meant to feel like glass does in the real world. It’s visually very impressive, and it all kind of works! You insta

CubeSats are fascinating learning tools for space

These are CubeSats. Satellites that are going to space—or at least, the ones I have here are prototypes. But these have one thing in common: they're all powered by either a Raspberry Pi, or a microcontroller. There are already Pis in space, like on Mark Rober's SatGus, on GASPACS, and the Astro Pis on the Space station. Another Pi is going up this weekend, which is why I'm posting this today. I'll get to that one, but I wanted to spend some time talking about two things that fascinate me: Raspb

Parts shortage is the latest problem to hit General Motors production

General Motors will temporarily lay off workers at its Wentzville assembly plant in Missouri. According to a letter sent to employees by the head of the plant and the head of the local union, a shortage of parts is the culprit, and as a result the factory will see "a temporary layoff from September 29-October 19." The plant is about 45 minutes west of St Louis and employs more than 4,000 people to assemble midsize pickup trucks for Chevrolet and GMC, as well as full-size vans. Not every employe

iOS 26 officially launches today, but some developers aren’t sure it should

Today is the day that iOS 26 finally emerges from beta and is officially launched. The headline feature is of course the Liquid Glass look, which has proved almost as controversial as the minimalist look of iOS 7 back in 2013. Apple has made some pretty substantial changes to the look of the operating system after beta testers complained about poor legibility and confusing design elements. Even so, some developers are not at all convinced that Liquid Glass is ready to be unleashed … Wired’s Cr

Your iPhone is about to look way different

is a senior reporter covering technology, gaming, and more. He joined The Verge in 2019 after nearly two years at Techmeme. Apple’s latest major iPhone update, iOS 26, releases today, and it has a new design language that gives just about everything on your iPhone a new look. Apple calls the design “Liquid Glass,” and it means that a lot of things on your iPhone will now have a glassy sheen. The edges of app icons look like they’re carved out of a chunk of glass. When you press and hold on tex

China says Nvidia violated anti-monopoly law after preliminary probe

China is one of Nvidia's largest markets, particularly for data centers, gaming and artificial intelligence applications. China's market regulator on Monday said that Nvidia violated the country's anti-monopoly law, according to a preliminary probe, adding that Beijing would continue its investigation into the U.S. chip giant. Shares of Nvidia were down around 2% in premarket trading. Late last year, China's State Administration for Market Regulation (SAMR) opened an investigation into Nvidia

Fall Equinox Is Next Week: What It Is and What It Looks Like

The official arrival of the season is the autumnal equinox, which occurs in the Northern Hemisphere next week. After a hot summer, the September equinox marks a welcome shift in the seasons for many folks. But what exactly is an equinox? It's all about Earth and its relationship with the sun. Here's how to understand, visualize and celebrate the autumnal equinox. Don't miss any of our unbias

Liquid Glass Could Be One of Apple's Most Divisive System Designs Yet

Apple revealed Liquid Glass as part of its WWDC announcement this June, with all the pomp usually reserved for shiny new gear. The press release promised a “delightful and elegant new software design” that “reflects and refracts its surroundings while dynamically transforming to bring greater focus to content.” Today it launches globally onto compatible Apple devices. If you haven’t encountered it yet, brace yourself. Inspired by visionOS—the software powering the Apple Vision Pro mixed reality

Whole-Genome Sequencing Will Change Pregnancy

The world of pregnancy is going to radically change, predicts Noor Siddiqui. “I think that the default way people are going to choose to have kids is via IVF and embryo screening,” she said at the WIRED Health summit last week. “There’s just a massive amount of risk that you can take off of the table.” Siddiqui is the founder and CEO of Orchid, a biotech company that offers whole-genome screening of embryos for IVF. By analyzing the DNA of different embryos before selecting which one to implant

Breaking: One UI 8 stable starts rolling out for the Galaxy S25 series

Joe Maring / Android Authority TL;DR Samsung has begun rolling out the first One UI 8 stable release for the Galaxy S25 series. The update is being gradually rolled out to users in South Korea, but we expect a rollout for users in the US and the rest of the world to follow very soon. After months of beta testing, Samsung is now following through on its One UI 8 expansion plans by finally rolling out stable One UI 8 based on Android 16 to its flagship, the Galaxy S25 series. Don’t want to mis

Page Object (2013)

When you write tests against a web page, you need to refer to elements within that web page in order to click links and determine what's displayed. However, if you write tests that manipulate the HTML elements directly your tests will be brittle to changes in the UI. A page object wraps an HTML page, or fragment, with an application-specific API, allowing you to manipulate page elements without digging around in the HTML. The basic rule of thumb for a page object is that it should allow a softw

You’re a slow thinker. Now what?

I'm not a quick witted person. In fact, I’ve always been worried about my brain’s slow processing time. But recently, I've realised that slow processing time is not as much of an issue as I thought it was. And even if I was wrong about that, I still think I’d do better for myself by leaning into it, instead of spending energy trying to fight it. In this essay, I want to talk about some ways I've been able to skirt around my lack of quick wittedness! To get what I mean by slow processing time,

We now know how Quick Share for iPhone will work, and there’s bad news (APK teardown)

Rita El Khoury / Android Authority TL;DR An Android Authority teardown has uncovered just how Quick Share will work for iPhones. Android owners can share a QR code with iPhone users to let them download files. However, files shared with iPhone users via Quick Share will first be uploaded to the cloud and retained for 24 hours. We’ve known since last year that Google is working on bringing Quick Share to iOS and MacOS. We recently discovered more evidence of the feature coming to iPhones, as

Google faces its first AI Overviews lawsuit from a major US publisher

Even though Google's AI Overviews were introduced with a comically rocky start, it's about to face a far more serious challenge. Penske Media, the publisher for Rolling Stone, Variety, Billboard and others, filed a lawsuit against Google, claiming the tech giant illegally powers its AI Overviews feature with content from its sites. Penske claimed in the lawsuit that the AI feature is also "siphoning and discouraging user traffic to PMC's and other publishers' websites," adding that "the revenue

Rolling Stone owner Penske Media sues Google over AI summaries

Google faces a new lawsuit accusing the company of illegally using news publishers’ content to create AI summaries that damage their business. The lawsuit comes from Penske Media (PMC), which owns industry publications such as Rolling Stone, Billboard, Variety, Hollywood Reporter, Deadline, Vibe, and Artforum. While Penske’s suit is the first targeting Google and its parent company Alphabet over showing AI-generated summaries in search, both publishers and authors have sued other AI companies o

Roblox hit with wrongful death lawsuit following a teen player's suicide

Following her son's suicide, Becca Dallas filed a potentially groundbreaking lawsuit against Roblox and Discord, accusing the platforms of wrongful death. As first reported by The New York Times, the lawsuit recounts the events leading up to Ethan Dallas' death, detailing his interactions with a player named Nate. According to the report, Nate was likely a 37-year-old man named Timothy O'Connor, who was previously arrested on charges of "possessing child pornography and transmitting harmful mate

Adding OR logic forced us to confront why users preferred raw SQL

Where This Story Begins In 2022, we had three different query interfaces. Logs had a custom search syntax with no autocomplete. Traces only had predefined filters - no query builder at all. Metrics had a raw PromQL input box where you'd paste queries from somewhere else and hope they worked. Each system spoke a different language. An engineer debugging a production issue had to context-switch not just between data types, but between entirely different mental models of how to query data. When

Setup options appeared in the Google Home app for wired versions of the Nest Cam Indoor (3rd gen), Nest Cam Outdoor (2nd gen), and Nest Doorbell (3rd gen), as reported by Android Authority. The options now appear to have been removed, but an eagle-eyed Redditor also found the new products locked up at Home Depot, ready to go on sale. Google has already confirmed that it plans to unveil new information about th

Automate compile_flags for C/C++ projects on the Zig build system

When using Zig’s build system for C/C++ projects, editors struggle to find include paths and provide proper code intelligence. compile_flagz solves this by automatically generating compile_flags.txt from your build.zig configuration. The Problem Recently I’ve been working on ROLLER, a decompilation project for the 1995 game, Fatal Racing (or Whiplash in NA). The game (known internally as Roller), is an early 3D game written in C with a bespoke engine. It also happens to be one of my favourite

The lawsuit also accuses Uber of imposing cleaning surcharges related

How an over-the-air update made Quilt’s heat pumps more powerful

Software might be eating the world, but it’s taking some industries longer than others to realize its full potential. From iPhones to Teslas, people have grown accustomed to software updates improving the stuff they already own. But outside consumer electronics and automobiles, over-the-air updates aren’t commonplace yet. Yet that’s beginning to change, starting with an unlikely product: heat pumps. Last week, heat pump startup Quilt said that it pushed an update last week to heat pumps alread

Android Auto could rollback one controversial change but introduce another (APK teardown)

Andy Walker / Android Authority TL;DR Google could reverse an Android Auto UI change that has upset many users. Instead of using colors from your phone’s wallpaper, Android Auto’s media player could use the album art as the background once again. However, while testing this reversal, Google appears to have messed up another visual aspect in Android Auto. Last month, Google began testing a simpler Material You-based interface for Android Auto, featuring background colors that match your phone

Our website looks like an operating system

I have a problem with many large, technical websites. Often times, I’ll want to refer to different pages at the same time. So I’ll CMD + click “a couple times” while browsing around and before I know it, I have 12 new tabs open – all indistinguishable from each other because they share the same favicon. PostHog.com has the same problem – especially as the site has grown from supporting a handful of paid products to over a dozen. As I looked for ways to solve this explosion of pages, I started
