Formally verifying a floating-point division routine with Gappa – part 1

We have recently released a set of optimized assembly-language routines for basic floating-point arithmetic, in Arm Optimized Routines, under an open-source license. These functions perform the same operations as hardware floating point instructions, for example addition, multiplication, and division. However, they are implemented using only integer 32-bit Arm instructions, for Arm CPUs without hardware floating point. Existing open-source libraries such as libgcc and compiler-rt offer similar

Exactly Six Months Ago, the CEO of Anthropic Said That in Six Months AI Would Be Writing 90 Percent of Code

With so many wild predictions flying around about the future AI, it’s important to occasionally take a step back and check in on what came true — and what hasn’t come to pass. Exactly six months ago, Dario Amodei, the CEO of massive AI company Anthropic, claimed that in half a year, AI would be "writing 90 percent of code." And that was the worst-case scenario; in just three months, he predicted, we could hit a place where "essentially all" code is written by AI. As the CEO of one of the buzzi

Pop Mart Unleashes Its Blind Box ‘Chucky’ Collection Just in Time for Halloween

AirPods Pro 3 don’t include a USB-C charging cable in the box

At this point, it is not exactly a surprise, but it is still noteworthy: If you’re buying the new AirPods Pro 3, make sure you have a USB-C charging cable or a wireless charger handy. Here are the details. Bring your own USB-C cable or wireless charger As Apple succinctly explains on the AirPods Pro 3 tech specs page: “USB‑C Charge Cable sold separately.“ While many users have more than enough charging alternatives at home, at work, and even in their cars, some might still be caught by surpr

Here’s everything Apple discontinued after the ‘Awe Dropping’ event

As it usually does, Apple discontinued a few products to make room for everything it announced during Tuesday’s event. Here’s the full list of products that Apple dropped, following the ‘Awe Dropping’ presentation.

It may look like a good time to spring for the new phone, but how bi

Clojure's Solutions to the Expression Problem

At times, to evolve your product, you need to rebuild it from scratch.

After Ukrainian testing, drone detection radar doubles range with simple software patch

As part of its unprovoked invasion, Russia has been firing massed waves of drones and missiles into Ukraine for years, though the tempo has been raised dramatically in recent months. Barrages of 700-plus drones now regularly attack Ukraine during overnight raids. Russia also appears to have upped the ante dramatically by sending at least 19 drones into Poland last night, some of which were shot down by NATO forces. Many of these drones are Shahed/Geran types built with technology imported from

While US stalls, Australia and Anduril move to put XL undersea vehicle into service

With Anduril’s help, Australia has done what the U.S. Navy has struggled to accomplish: transition an extra-large undersea drone from white board to under contract in just three years. Anduril announced Tuesday that a fleet of its XL uncrewed undersea vehicle (XLUUV) “Ghost Shark” will begin operations in Australian waters next year under a massive AUS$1.7 billion (US$1.1 billion) contract. The five-year award structure is the defense-startup holy grail; it’s a program of record that essential

Apple is slowly morphing AirPods into an always-on wearable

The AirPods Pro 3 Apple introduced at the iPhone 17 event yesterday have better active noise cancellation and foam-filled ear tips, but their most important new feature is a subtle one: Apple came up with even more reasons for you to never take them out. Wearing headphones while you're talking to someone or interacting in public was at one point a social faux pas, but the ubiquity of AirPods and new features Apple has added have started to change that.

NASA Says Its Mars Rover Has Detected Possible Signs of Life on the Red Planet

NASA has announced that its Perseverance Mars rover spotted "potential biosignatures" in an ancient dry riverbed last year. Samples collected from a rock dubbed "Cheyava Falls" contain a structure that hints at the possibility of having a biological origin, according to the space agency, but more research needs to be completed to draw any conclusions about the presence of life on the Red Planet. "The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, an

Android 16 QPR1’s source code is nowhere to be found, but Google swears it’s coming

Mishaal Rahman / Android Authority TL;DR Google has delayed releasing the source code for Android 16 QPR1, worrying custom ROM developers who rely on timely AOSP (Android Open Source Project) updates. While Google typically publishes source code within 48 hours of a new release, it has been a week, breaking a long-standing precedent for the community. Google confirmed the code is coming “in the coming weeks,” but the situation has reignited concerns about the company’s commitment to open-sour

The best battery life iPhone 17 Pro models are not sold in every country

At Apple’s event yesterday, battery life was one of the big marketing points for the iPhone 17 Pro series. However, it turns out that the best battery life models of the Pro and Pro Max are not actually available to buy worldwide. In the United States, Apple quotes 30 hours streaming video playback for iPhone 17 Pro and 35 hours for iPhone 17 Pro Max. But in the UK, Europe, and elsewhere, the tech specs list battery life of 28 hours and 33 hours respectively, two hours less than their US model

Seven iPhone Air details you might’ve missed during yesterday’s keynote

Apple acknowledges iPhone Camera Control is overly complicated with iOS 26 change

I absolutely love the Camera Control on my iPhone — just not in its default state. With the final version of iOS 26, Apple is taking the first step toward pulling back the overly complex Camera Control with one simple change. Camera Control is a highly requested feature iPhone users have wanted physical camera buttons since at least the iPhone 4 in 2010. That’s why Apple added the ability to use the volume buttons to snap photos in the Camera app way back then. More recently, Apple brought th

A closer look at the AirPods Pro 3: ANC, Live Translation and heart-rate tracking

The AirPods Pro 3 are a big upgrade over the AirPods Pro 2. Even though Apple has continuously added new features to those earbuds over the last three years, it hasn’t changed the design or shape of the earbuds since the first model arrived in 2019. With the AirPods Pro 3, you might not notice those tweaks until you remove the new ear tips, and the most impactful upgrades are all on the inside. After my brief hands-on immediately following the iPhone 17 launch yesterday, I’ve since spent more ti

‘Traumatika’ Puts a Gruesome Spin on the Idea of Facing Your Demons

The new indie horror film Traumatika opens with a title card informing us of the “five forms of childhood trauma,” unsubtly announcing what’s about to happen over the next 80 minutes. Then we’re in the Egyptian desert, circa 1910, watching an anguished man bury a sinister-looking figurine in the sand. Only then do we arrive in the 21st century, where terrible things are very much afoot. The flashback adds a little bit of context, but it feels unnecessary; a cursed object is a not-uncommon horro
