Hypervisor in 1k Lines

Hypervisor in 1,000 Lines ​ WARNING This book is work in progress. Hey there (maybe again)! In this book, you'll learn how to build a minimal RISC-V hypervisor which can boot Linux-based operating systems. This is a sequel to the online book Operating System in 1,000 Lines. In that book, you have learned how to build a minimal operating system from scratch in C, but this time, we'll start from scratch (again) in your favorite language, Rust! From scratch means we'll start from the bare-metal

US High school students' scores fall in reading and math

WASHINGTON (AP) — A decade-long slide in high schoolers’ reading and math performance persisted during the COVID-19 pandemic, with 12th graders’ scores dropping to their lowest level in more than 20 years, according to results released Tuesday from an exam known as the nation’s report card. Eighth-grade students also lost significant ground in science skills, according to the results from the National Assessment of Education Progress. The assessments were the first since the pandemic for eight

Axial twist theory

Scientific theory in vertebrate development Axial twist Schema of the proposed development of the axial twist. Developmental phases are (from top to bottom): (1) the embryo turns on its left side; (2) the anterior head grows in the same direction, but the rest of the body grows oppositely into a twist. So that ultimately (3) external bilateral symmetry is regained. Note that there is no evolutionary pressure for internal symmetry so the heart (and other organs) remain asymmetric. Details System

Coursera Will Soon Have AI Personas to Help You Practice for a Job Interview

Generative AI is changing the way we learn. Tools like NotebookLM or chatbots make it easier to absorb information… or cheat. Global online learning platform Coursera is taking action by adding new features to help students master skills while deterring cheating. I've taken several Coursera courses and revisited them in recent months, only to see new sections dedicated to working with AI in the context of the course subject. This makes sense not only for the courses themselves, but also for the

Apple’s new Center Stage Camera always keeps you in frame

The biggest takeaway from the iPhone 17’s new front camera? You won’t have to rotate your phone to take a landscape selfie. The new square sensor allows for multiple aspect ratios to be captured at once; you just have to click to expand or switch between compositions. And that’s just the start of the phone’s new features, as revealed at Apple’s iPhone 17 reveal event, not to mention the implications of the iPhone 17 Pro’s potent camera on manufacturers targeting vloggers and content creators.

All of the new iPhones start with 256GB of storage. Finally.

There's a lot to like about the new iPhone lineup: new selfie cameras , a new unibody frame and a even a super-thin iPhone, if that's your thing. All of the new phones share one important upgrade you might have missed during Apple's 72-minute livestream, though: they all start at 256GB of storage. For the first time in four years, Apple raised the base-level storage on its entire iPhone lineup. Since the iPhone 13, Apple's phones have started at 128GB for the cheapest configuration. Now, the iP

Sigourney Weaver Is a Fan of ‘Alien: Earth,’ Too

We’re on record saying just how good the new FX show Alien: Earth is but who are we? Just some weird website that writes about pop culture and technology. The real voices you want to weigh in on an Alien show are the people who are a part of it, and at the top of that list is Sigourney Weaver. Weaver played Ellen Ripley, or some version of her, in four Alien movies from 1979 to 1997 and is clearly the go-to when it comes to Alien. Especially because she, unlike original director Ridley Scott, h

The 15 Wildest, Coolest Films We Can’t Wait to See at Fantastic Fest 2025

The most fantastic time of year is here again. io9 is about to head down to Austin, Texas, for a week of fun, fucked-up films at Fantastic Fest, one of the coolest, most unique genre film festivals in the entire world. It’s a festival that focuses on only showing the weirdest, most out-there, totally badass films, and we’re excited to jump right in as always. What makes attending Fantastic Fest difficult, though, is that every single movie sounds awesome. It was curated that way. So how do you

I Held Apple's Wildly Thin iPhone Air, and I'm Already Obsessed

Apple debuted its super-slim iPhone Air on Tuesday, and after getting my hands on the device at Apple Park in Cupertino, California, I'm amazed at just how thin and lightweight it really is. At just 5.6mm thick and 165 grams, it's one of those phones you may just have to hold to understand its appeal. I look forward to finding out if what's on the inside lives up to that show-stopping design. With the iPhone Air in one hand and my iPhone 16 Pro Max in the other, the difference between the two d

CNET Debates: Is Apple's New Crossbody Strap a Great Idea or a Terrible One?

One thing you can be sure of during an Apple event is that it will generate immense quantities of discourse among CNET's seasoned nerds -- and no, we don't always agree with one another. Is the iPhone Air totally pointless and uncalled for, or the best design innovation since very thinly sliced bread? Both can be true, depending on whom you ask. Watch this: Everything Announced at Apple's iPhone 17 Event in 7 Minutes 07:18 Among the many announcements on Tuesday that sparked conflicting opini

From mixers to pitch-offs — your brand event belongs at TechCrunch Disrupt 2025

Last year’s TechCrunch Disrupt Side Events drew hundreds of founders, investors, and operators after hours — from intimate roundtables to lively happy hours to full-on pitch competitions.

As a Side Event host during “Disrupt Week” (October 25–31), you’ll tap into an audience of 10,000+ attendees, plus the broader Bay Area tec

As AI Reigns, Students' Math and Reading Scores Just Hit an All-Time Low

The US Education Department, which the Trump administration is actively attempting to dismantle, has released the latest math and reading test scores for American high-school seniors — and they're an absolute disaster. As the Wall Street Journal reports, the scores have hit an all-time low, even by America's historically underwhelming standards. It's a worrying sign that the rapid rise of technologies like AI — combined with other likely factors, like the lingering effects of the COVID-19 pande

MAGA Congressman Explains Trump’s Signature in Epstein Birthday Book by Floating Autopen Conspiracy

A Congressional document dump of Jeffrey Epstein files on Monday has created a certifiable public relations nightmare for the Trump administration, and its allies are currently scrambling for some sort of explanation as to why what looks a whole helluva lot like the President’s signature would be found on an alleged birthday letter included in the trove. On Tuesday, Rep. Tim Burchett (R-Tennessee) offered up the latest excuse: some sort of conspiracy involving a signing machine called an autopen

Why SpaceX made a $17B bet on the direct-to-cell market

SpaceX just fired off one of the biggest shots yet in the spectrum wars, agreeing to pay $17 billion to take over a massive chunk of wireless airwaves from EchoStar for Starlink’s Direct-to-Cell services. The deal is the most aggressive signal yet that SpaceX wants to rule the satellite-to-phone market. The significance of the sale, which sees SpaceX paying a mix of $8.5 billion in cash and $8.5 billion in SpaceX stock, centers around a finite resource: spectrum. Spectrum refers to the range o

Decades-Old Waste Barrels Are Creating Toxic Dead Zones off LA’s Coast

Until 1972, the Pacific waters of Southern California served as a dumping ground for hazardous and industrial wastes. More than 50 years later, corroded metal barrels still litter the seafloor off the coast of Los Angeles, and scientists are only beginning to understand the consequences of casually tossing them into the ocean. Images of the barrels first surfaced in 2020, with some of them encircled by mysterious white halos on the seafloor. Experts initially linked the barrels to DDT—a toxic p

Apple's Live Translation Is Fluent in Convenience, Not Culture

Apple wants you to believe the future of travel fits neatly inside your AirPods. At Apple's "awe dropping" event on Sept. 9, the tech giant unveiled the AirPods Pro 3, introducing a range of features like heart rate sensing, "world's best" active noise canceling and the headline-grabbing Live Translation, a feature that lets you hear another language instantly translated into your own, in real time. On paper, it sounds magical. In practice, something about it feels… off. There's a weirdly dism

Apple raises iPhone Pro starting price in U.S. for first time since 2017

A next generation iPhone 17 is held during an Apple special event at Apple headquarters on September 9, 2025 in Cupertino, California. Apple increased the starting price of one of its iPhone models and replaced another with a pricer device on Tuesday, as analysts and investors widely expected. Apple's iPhone 17 Pro now starts at $1,099. That's $100 more than last year's iPhone 16 Pro. Apple also replaced last year's $899 iPhone 16 Plus in its lineup with a new thin-and-light device called the

iPhone Air hands-on: The super sleek precursor to Apple’s upcoming foldable

Apple might not admit it (at least not yet), but the iPhone Air is more than just a slimmed-down version of the company's latest handset or a more sophisticated take on its usual Plus model. It's a super sleek preview of its upcoming foldable. Now this might seem like a stretch and there's something to be said about the difference between a traditional OLED display and one that's meant to be bent. However, the arrival of a foldable iPhone has become one of the tech world's worst-kept secrets. S

The Man Who Proposed Simulation Theory Has a Dire Warning

More than 20 years ago, futurist intellectual Nick Bostrom upended the psyches of tech bros the world around when he proposed in a 2003 Philosophical Quarterly paper that we all may be living in a computer simulation. Beloved by such strange bedfellows as Elon Musk, Bill Gates, and Sam Altman, Bostrom has released two other influential missives — 2014's "Superintelligence: Paths, Dangers, Strategies," which detailed the ways AI could become smarter than humans, and 2024's "Deep Utopia: Life and
