‘Crazy conspiracist’ and ‘unhinged comedian’: Grok’s AI persona prompts exposed

The website for xAI’s Grok chatbot is exposing the system prompts for several of its AI personas, including a “crazy conspiracist” that seems designed to handhold a user into beliefs that “a secret global cabal” controls the world. TechCrunch has confirmed the system prompt exposure, first reported on by 404 Media. They include instructions for a range of AI personas, like Ani, its flagship romantic anime girlfriend who “is secretly a bit of a nerd, despite [her] edgy appearance.” The exposure

If I had to start my entire Apple ecosystem from scratch, these would be my top picks

Let’s say there was some catastrophic event all of a sudden, and for whatever reason I needed to replace all of my Apple products at once. What would I end up buying? We’ll explore this scenario, and this’ll hopefully serve as useful advice for anyone just looking to expand their Apple ecosystem. For context, my ecosystem currently consists of a 128GB iPhone 16 Pro, a stainless steel Apple Watch Series 8, an M3 iMac with 2TB/24GB, an M4 MacBook Pro with 512GB/16GB, a 128GB iPad (A16), and a lig

Show HN: I built a toy TPU that can do inference and training on the XOR problem

Nobody really understands how TPUs work…and neither do we! So we wanted to make this because we wanted to take a shot and try to guess how it works–from the perspective of complete novices! We wanted to do something very challenging to prove to ourselves that we can do anything we put our mind to. The reasoning for why we chose to build a TPU specifically is fairly simple: None of us have real professional experience in hardware design, which, in a way, made the TPU even more appealing since w

Musk's Starlink suffers apparent outage as SpaceX launches more satellites

Satellite internet service Starlink, which is owned and operated by Elon Musk's SpaceX, appeared to suffer a brief network outage on Monday, with thousands of reports of service interruptions on Downdetector, a site that logs tech issues. The outage marked the second in two weeks for Starlink. SpaceX did not immediately respond to a request for comment. The network's July 24 outage lasted for several hours, with SpaceX Vice President of Starlink Engineering Michael Nicolls blaming the matter o

Three highlights from Apple’s two-day event on privacy and AI

A few months ago, Apple hosted the Workshop on Privacy-Preserving Machine Learning, which featured presentations and discussions on privacy, security, and other key areas in responsible machine learning development. Now, it has made the presentations public. Here are three highlights. As it did recently with the presentations from the 2024 Workshop on Human-Centered Machine Learning, Apple published a post in its Machine Learning Research blog with a few videos and a long list of studies and pa

HR Giant Workday Got Hacked

Workday, a company that provides human resources technology to over 11,000 corporations and 70 million users worldwide, announced in a classic Friday news dump that it suffered a data breach. The company did not disclose how much information was stolen by the hackers, but did reveal that information—including the names, email addresses, and phone numbers—of some users was compromised. The company said the breach hit some of its third-party customer relationship databases. If any other data was

Workday says hackers used social engineering to access personal data during a breach

Human resources technology company Workday has confirmed that a data breach has affected its third-party CRM platform. In a blog post announcing the breach, the company said that a social engineering campaign had targeted its employees, with threat actors posing as IT or HR in order to trick employees into sharing account access or personal information. The company says that while the threat actors were able to access some information from the CRM, there is no indication of any access to custom

ERMAC Android malware source code leak exposes banking trojan infrastructure

The source code for version 3 of the ERMAC Android banking trojan has been leaked online, exposing the internals of the malware-as-a-service platform and the operator’s infrastructure. The code base was discovered in an open directory by Hunt.io researchers while scanning for exposed resources in March 2024. They located an archive named Ermac 3.0.zip, which contained the malware’s code, including backend, frontend (panel), exfiltration server, deployment configurations, and the trojan’s build

The First Trailer for ‘Keeper’ Deepens Its Creepy Mystery

Some filmmakers take a long time between projects. Others are more rapid-fire. In the time since Oz Perkins popped up in Jordan Peele’s last film, 2022’s Nope, playing a small role as a movie director, he released Longlegs (the highest-grossing indie film of 2024) as well as this year’s The Monkey—and in a few months, Keeper will hit theaters too. Peele has the sports horror film Him, which he produced, coming out soon, but his next directorial effort won’t arrive until October 2026. Different

Texas attorney general accuses Meta, Character.AI of misleading kids with mental health claims

Texas attorney general Ken Paxton has launched an investigation into both Meta AI Studio and Character.AI for “potentially engaging in deceptive trade practices and misleadingly marketing themselves as mental health tools,” according to a press release issued Monday. “In today’s digital age, we must continue to fight to protect Texas kids from deceptive and exploitative technology,” Paxton is quoted as saying. “By posing as sources of emotional support, AI platforms can mislead vulnerable users

macOS Tahoe 26 beta 7 now available to developers

As Apple enters the final stretch of the post-WWDC beta season, it has moved now to the wekly schedule of developer releases. The seventh batch of betas is now rolling out. Here’s what to expect. Last week, macOS Tahoe 26 developer beta 6 brough mostly under-the-hood improvements, building on top of the previous versions which, among other things, introduced a new Macintosh HD icon, new screensavers, and improvements to tab visibility in apps like Safari and Terminal. The build number for macO

Substack turns on iOS in-app payment option for all paid newsletters

Substack now lets users subscribe to any paid publication via an in-app purchase from the official iOS app. The news comes after the company tested the feature with 30,000 creators. This makes subscribing to something a much speedier affair, with the entire process taking just a few taps on the old smartphone screen. Prior to this, it wasn't always possible to upgrade to a paid subscription directly in the app. Showing off that it's more expensive to use iOS. (Substack) However, there's a fai

NordVPN will discontinue Meshnet on December 1

NordVPN announced today in a blog post that its Meshnet feature will shut down on December 1. All aspects of Meshnet will stop working on that date, though nothing else about NordVPN will be affected. If you were using Meshnet to connect computers, route web traffic through a personal device or share files, you'll need to find another solution by December. As I mentioned in my NordVPN review , Meshnet was one of the most envelope-pushing features on any VPN, letting users link their devices thr

The Cutaway Illustrations of Fred Freeman

During the two-year research for our book LOOK INSIDE we discovered many amazing illustrations and artists that, for one reason or another, did not make it into the final version of the book. It would be a pity to leave these forgotten on a drawer, so during the next few weeks we will present here some of these masters of the cutaway. A while ago we wrote here about Frank Soltesz, an American illustrator active from the 30’s to the 60’s, and author of a marvelous series of architectural cutaw

Turning an iPad Pro into the Ultimate Classic Macintosh (2021)

I’ve started work on the next in my 1-bit Woodblocks series: “Tekagami” (Ito Shinsui’s “Hand Mirror”). So it’s a good time to talk about how I turned an iPad Pro into the ultimate Classic Macintosh. Emulators Both Macintosh emulators available on iOS we’re ported by @maczydeco who has done an amazing job making them feel truly at home on iOS. Many thanks! They need to be built from source using Xcode but it’s a pretty straight forward process. Mini vMac Supports System 1.1 to 7.5.5 Limited

After recent tests, China appears likely to beat the United States back to the Moon

In recent weeks, the secretive Chinese space program has reported some significant milestones in developing its program to land astronauts on the lunar surface by the year 2030. On August 6, the China Manned Space Agency successfully tested a high-fidelity mockup of its 26-ton "Lanyue" lunar lander. The test, conducted outside of Beijing, used giant tethers to simulate lunar gravity as the vehicle fired main engines and fine control thrusters to land on a cratered surface and take off from ther

Substack writers can now direct US readers to (often cheaper) web-based subscriptions on iOS

Newsletter subscription platform Substack will begin taking advantage of an option on the U.S. App Store that allows users to make purchases outside of Apple’s in-app purchasing system. This functionality is permitted by a change to the App Store’s rules in May, as a result of Epic Games’ antitrust lawsuit against the tech giant. Since then, a number of top apps have moved to offer in-app purchase links that point to their own websites, including Spotify, Patreon, and the Amazon Kindle app, amo

Texas AG accuses Meta, Character.AI of misleading kids with mental health claims

Countrywide natural experiment links built environment to physical activity

Study design We conducted a countrywide, prospective, longitudinal physical activity study of US residents that evaluated their physical activity levels within the context of the walkability of their built environments before and after relocation (‘participants’). We leveraged the naturally occurring physical activity data that was captured by a health app on participants’ phones to compare each person’s physical activity levels before and after they relocated to a different area within the USA

MSNBC Rebrands as MS NOW, but the Web Domain Is for Korean Snowmobiles

Cable news channel MSNBC is going to rebrand as My Source News Opinion World, or MS NOW, according to a new report from the New York Times. The change is happening because Comcast’s NBCUniversal is spinning off many of its cable TV assets into a new company called Versant, severing ties with the “NBC” part of MSNBC. But it’s not yet clear where you’ll be able to find MS NOW on the web. That’s because the web domain msnow.com is registered in Gyeonggi, South Korea by someone who is clearly not t

TeraWulf stock jumps more than 10% as Google boosts stake in datacenter operator

TeraWulf stock rallied more than 10% after Google hiked its stake in the bitcoin miner and datacenter operator as it funds an expansion of its Lake Mariner, New York, facility. As part of the deal, Google will offer up to $1.4 billion in additional backstop, bringing its total to about $3.2 billion. It hikes Google's stake in TeraWulf to 14% from 8% and enables the company to buy about 32.5 million shares of the company's stock. CEO Paul Prager said in a release that the agreement solidifies t

This $320 Kit Brings the BlackBerry Classic Back From the Dead

People are bored of their phones. So bored of their big, boring glass and metal slabs that they can’t help but dump all over phones like Nothing’s Phone 3 that don’t look like boring-ass bricks. But apparently people are so bored of their phones that somebody went and made a whole-ass kit that replaces the guts of the long-dead BlackBerry Q20, or “Classic,” with new components and effectively modernizes it with Android. Beloved for its QWERTY keyboard and BlackBerry OS (who remembers BBM?), the

These Chunks of Ice Move All By Themselves, Thanks to a Cool Engineering Trick

It looks like something straight out of a Ouija board horror movie, but frosty—researchers have figured out how to make ice move by itself. A video capturing the creepy dynamic features an ice disk melting on a metal surface etched with an asymmetrical herringbone pattern. The ice and its small puddle slowly start to move sideways before suddenly picking up speed and slingshotting across the metal plate. The researchers suggest that this sort of independent movement could one day generate power

Picking a Spot for NASA’s Lunar Nuclear Reactor Is Trickier Than It Sounds

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the Moon by the time China plans to land the first taikonaut, what China calls its astronauts, there by 2030. Apart from the geopolitical importance, there are other reasons why this move is critically important. A source of nuclear energy will be

Why Paradigm built a spreadsheet with an AI agent in every cell

Anna Monaco has been building AI agents since before the term “AI agents” was even a thing. After building numerous chatbots, she started looking for other types of interfaces that made sense for AI agents and landed on spreadsheets. “I had this personal pattern, and I noticed that a lot of other people had this pattern, of putting very important CRM data in spreadsheets just because it was the most flexible thing,” Monaco told TechCrunch. “But it was actually a pain to maintain. There’s so muc

There’s Something Really Suspicious About the Way This Star Died

Stellar death is a complex and mysterious process — but in the case of a supernova known as 2023zkd, things were more gruesome than any astronomer had ever seen before. As its name suggests, this supernova — the fabulous astronomical term for the explosive death of a star — was first spotted back in 2023, when Southern California's Zwicky Transient Facility zeroed in on it thanks to new AI algorithms designed to detect such brilliant blasts. This supernova, however, was different. It appeared,

This vintage ‘Apple Watch’ face needs to exist

Apple has designed all sorts of Apple Watch faces in the 10+ years since the product launched. Still, there’s one face that Apple should build and release as soon as possible, please. That face, of course, is the one from the “Apple” watch that predated Apple Watch by two decades. The anonymous X account that goes by the name System Settings has designed their take on how it could look: i designed a watch face inspired by this vintage Apple Watch what do you think 👀 https://t.co/N6k4YCmw1u

Apple's Mac mini M4 is back on sale for $499

Buying a computer, especially one from Apple, is typically going to cost you a pretty penny. So sales are critical for getting all the devices we want.
