The borrowchecker is what I like the least about Rust

Written 2025-07-18 Among the 2010's cohort of programming languages, Rust is probably the most widely lauded. The main selling point of Rust is that it manages to combine speed and low-level control with a high level of bug-resistance, more commonly referred to as safety. The main innovation of Rust - really, its claim to fame - is its borrowchecker: the part of its compiler that enforces Rust's ownership rules and thereby allows Rust to achieve all the memory safety that garbage collected lan

At Least 750 US Hospitals Faced Disruptions During Last Year’s CrowdStrike Outage, Study Finds

When, one year ago today, a buggy update to software sold by the cybersecurity firm CrowdStrike took down millions of computers around the world and sent them into a death spiral of repeated reboots, the global cost of all those crashed machines was equivalent to one of the worst cyberattacks in history. Some of the various estimates of the total damage worldwide have stretched well into the billions of dollars. Now a new study by a team of medical cybersecurity researchers has taken the first

Could OpenAI's rumored browser be a Chrome-killer? Here's what I'm expecting

Omer Taha Cetin/Anadolu via Getty Images Sometime soon, perhaps as early as next week, OpenAI will follow up on its release of ChatGPT agent with its AI-enabled web browser. Officially, neither OpenAI nor its usually chatty CEO, Sam Altman, has anything to say about this browser. Unofficially, it's an open secret that the company is working on one to compete not just with the already shipping AI-enabled web browsers, Perplexity Comet, and Dia, but with the 800-pound gorilla of web browsers, Go

Mr Browser – Macintosh Repository file downloader that runs directly on 68k Macs

What is MR Browser? MR Browser is a small utility app allowing very old Macs from the 90's that are too old to use a normal web browser, but are new enough to connect to the internet through TCP/IP, to access Macintosh Repository online services, e.g. to directly download files without the help of a modern computer. For now, it's limited to only listing files smaller than 1GB, considering it's only meant to run on mid 90's System 7 environments. Note: Before downloading files with MR Browser, to

Why AI is moving from chatbots to the browser

Happy Friday. I’m back from vacation and still getting caught up on everything I missed. AI researchers moving jobs is getting covered like NBA trades now, apparently. Before I get into this week’s issue, I want to make sure you check out my interview with Perplexity CEO Aravind Srinivas on Decoder this week. It’s a good deep dive on the main topic of today’s newsletter. Keep reading for a scoop on Substack and more from this week in AI news. From chatbots to browsers So far, when most people

Row Polymorphic Programming

Sometimes, especially when dealing with business logic, we have to deal with data that comes in from the real world, or elsewhere, naturally very messily typed, leading to nasty type signatures and messes of macros or code generation to build data structures from a schema. Row polymorphism can help us by abstracting over the fields contained in a record type in the type signature, letting us define records based on data, concatenate records together, and define functions that are generic across

Lettuce Grow Indoor Farmstand Review: Grow Your Own

Upon receiving the Lettuce Grow Indoor Farmstand in the mail, I did not expect that I’d be enjoying some tea before I’d even unwrapped all the parts. “Is that … Zooey Deschanel? With a Dollar Tree Property Brother?” my husband asked, peering over my shoulder as I unpacked various tubes and parts. And indeed, among the boxes was a glossy handout of a slightly younger-looking Zooey, standing with a man who did vaguely resemble her current husband, Jonathan Scott, of Property Brothers fame. Turns

Perplexity’s Comet is the AI browser Google wants

is a news writer who covers the streaming wars, consumer tech, crypto, social media, and much more. Previously, she was a writer and editor at MUO. Perplexity has just launched its agentic answer to Google Chrome — it’s called Comet, and it knocked out a slate of tasks on my behalf, though I think I could’ve done some faster myself. The new AI-powered browser is currently only available to Perplexity Max subscribers or through an early access waitlist, and it’s supposed to simplify the way you

This new browser won't monetize your every move - how to try it

Screenshot by Jack Wallen/ZDNET I didn't think the world needed yet another web browser. However, when I considered the potential, a few issues bubbled to the surface. Also: I speed-tested 11 browsers - and the fastest might surprise you Some web browsers were created by companies with the hope of monetizing anything and everything. From search deals with Google and crypto-mining ads to sponsored content and just about every other way they can make a buck off your browsing. After mulling over

Too many open browser tabs? This is still my favorite solution - and has been for years

NoSystem images/Getty Images How many browser tabs do you have open right now? If you're like most people who spend their workday in front of a PC or Mac, the answer is probably "too many to count," and you're staring at a row of icons that offer only the faintest clue of what's on the tab associated with each one. Good luck remembering what's on each page when all you can see are favicons for each tab Screenshot by Ed Bott/ZDNET When tab overload strikes, the usual cure is to declare tab ban

When is tech not hype? Tulips, toilets, trains and tabs

What do I do when I first wake up? I grab my phone. I'm reading the news, browsing Reddit, reading articles on HN, looking up the weather and anything else I might need to know about during the day. It's not until I open my tabs view, to switch back to something, that I realise I've managed to open half a dozen tabs within the space of minutes. In 2004, Mozilla Foundation placed a two-page ad in the New York Times announcing version 1.0 of Firefox. "Are you fed up with your web browser?" the ad

Do Student Loan Borrowers in SAVE Need to Do Anything Before Aug. 1?

Interest will restart for SAVE borrowers whose loans remain in a general forbearance on Aug. 1. Viva Tung/CNET As the old adage goes, the only constant student loan borrowers enrolled in SAVE have experienced over the past two years is a perpetual state of change. Last week, the Department of Education announced that interest would resume for the nearly 8 million borrowers in the Saving on a Valuable Education plan on Aug. 1. That gives borrowers roughly two weeks to decide if they want to mov

I tested a new browser that makes Chrome feel outdated

Karandeep Singh / Android Authority AI is embedding itself into every nook of our digital lives faster than Elon Musk can type his next obnoxious tweet. First, it was an app that could talk to you in a natural voice. Then it spread to everyday voice assistants. And now, it’s coming — strong-armed — for our main work app: web browsers. Google is pushing hard to make Gemini a core part of Chrome. The makers of Arc have already moved on to an AI-first browser. OpenAI is rumored to be working on i

Pixel Piranhas

I really hate it when I’m exposed to some horrible news online, and feel powerless. There is nothing I can do, I am not responsible, and yet at the same time I have this feeling “this shouldn’t be happening”. There is a temptation to immediately react – if it was printed, I would crumple up the paper and throw it away – yet, reading pixels on the screen I don’t have the right gesture to express my discontent. So I made this little browser extension. Click on a button, and a horde of cursor

ASML shares drop 6.5% after the chip giant says it can't confirm that it will grow in 2026

An icon of ASML is displayed on a smartphone, with an ASML chip visible in the background. ASML on Wednesday warned of the possibility of no growth in 2026, even as it beat top and bottom line expectations for the second quarter. ASML's guidance for the current quarter missed expectations while it narrowed its own forecast for the rest of the year. Shares of ASML dropped 6.5% in early trading, shortly after European markets opened. Like many companies in the semiconductor industry, ASML has

OpenAI's ChatGPT-powered browser is codenamed 'Aura'

OpenAI is following Perplexity and is working on its own AI-powered browser codenamed "Aura." X user Tibor found references to "Aura," which is probably the codename for the new OpenAI browser. There are already mentions of "is Aura" ("mini-root," which is similar to checks for Android, iOS, or Electron/ChatGPT Windows desktop app), "is Aura Sidebar," and "in Aura" in the ChatGPT web app. Reuters previously reported that OpenAI is building a Chromium-based Chrome alternative that will use gen

IDC: Emerging markets helped Apple offset iPhone slowdown in China during Q2

During the second quarter of 2025, Apple saw a modest gain in iPhone shipments, holding its worldwide ground amid slowing demand in China. Here are IDC’s preliminary numbers for the quarter. Emerging markets offset Apple’s China dip, while Samsung pulls ahead IDC’s Worldwide Quarterly Mobile Phone Tracker (via AppleInsider) shows that Apple shipped 46.4 million iPhones in Q2 2025 (up 1.5% year-over-year). That was enough to secure second place globally, behind Samsung’s 58 million units, and a

Nvidia chips become the first GPUs to fall to Rowhammer bit-flip attacks

Nvidia is recommending a mitigation for customers of one of its GPU product lines that will degrade performance by up to 10 percent in a bid to protect users from exploits that could let hackers sabotage work projects and possibly cause other compromises. The move comes in response to an attack a team of academic researchers demonstrated against Nvidia’s RTX A6000, a widely used GPU for high-performance computing that’s available from many cloud services. A vulnerability the researchers discove

I tried Perplexity's Comet AI browser, and I like where it's going (but it's not there yet)

solarseven/Getty Images Perplexity Comet isn't the first AI-powered web browser to arrive. That honor goes to Dia, but thanks to the popularity of Perplexity as an AI-enabled search engine and chatbot, it's getting a lot of attention. It deserves it.

It's designed from the ground up to use AI to automate tasks and improve your workflow. What Comet is aiming for Its archite

Apple profits means iPhone users still get no real browser choice, says group

A web advocacy group says that iPhone users still get no real web browser choice more than a year after this was supposed to happen under antitrust legislation. The non-profit Open Web Advocacy (OWA) claims Apple deliberately places obstacles in the path of developers, and that’s because doing so protects a large slice of its profits … In theory, Apple allows choice Since the first iPhone, Apple retained exclusive control over web browsing on the device. Even when third-party browsers were al
