A cryptography expert on how Web3 started, and how it’s going

The term Web3 was originally coined by Etherium cofounder Gavin Wood as a secure, decentralized, peer-to-peer version of the Internet. The idea was to build an Internet based on blockchain technology and a peer-to-peer network, without the need for large data centers or third-party providers. These days, however, blockchain is most famous as the tool enabling cryptocurrencies. Most recently, the Trump administration has taken on a pro-cryptocurrency stance, boosting blockchain’s popularity and m

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!

Things you can do with a debugger but not with print debugging

Things you can do with a debugger but not with print debugging People do or do not use debuggers for a variety of reasons. For one thing, they are hard to setup in many codebases. Second, you can’t use them when your application is running on remote environments (such as kuberenetes). So, anecdotally, I have seen way more people using Print/ log.Debug compared to a debugger. Which is a shame, because while debug logging is convenient at times, debuggers can do some things which you can’t easil

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

NASA finds Titan's lakes may be creating vesicles with primitive cell walls

NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn's moon Titan. Titan is the only world apart from Earth that is known to have liquid on its surface. However, Titan's lakes and seas are not filled with water. Instead, they contain liquid hydrocarbons like ethane and methane. On Earth, liquid water is thought to have been essential for the origin of life as we know it. Many astrobiologists have wondered whether Titan's liquids could

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

iPhone 17 Pro vs. iPhone 14 Pro: Why this year's model may be worth the upgrade

Follow ZDNET: Add us as a preferred source on Google. As a current iPhone 14 Pro Max user, I still feel like my three-year-old iPhone gives me everything I need from a smartphone. Sure, it may still have a Lightning Port and no support for Apple Intelligence, but I get around those very minor discomforts by using a MagSafe charger and ChatGPT. Truth be told, the Apple Intelligence features haven't wowed me enough to make me fork over $1,000 on a newer iPhone. Also: Apple Event live updates: Ev

Immunotherapy drug clinical trial results: half of tumors shrink or disappear

Over the past 20 years, a class of cancer drugs called CD40 agonist antibodies have shown great promise—and induced great disappointment. While effective at activating the immune system to kill cancer cells in animal models, the drugs had limited impact on patients in clinical trials and caused dangerously systemic inflammatory responses, low platelet counts, and liver toxicity, among other adverse reactions—even at a low dose. But in 2018, the lab of Rockefeller University’s Jeffrey V. Ravetch

Apple Thinks Orange Is the New Black. It Isn't

Yes, the iPhone Pro has officially gone gaudy orange… and, I think we're supposed to pretend this is exciting. Don't miss any of our unbiased tech content and lab-based reviews.

New iPhones use Apple N1 wireless chip—and we’ll probably start seeing it everywhere

Apple’s Best New iOS 26 Feature Has Been on Pixel Phones for Years

Ever since I was a child, I’ve despised answering the phone when an unknown number calls. Who could be on the other end? Literally anyone: an acquaintance, a telemarketer, a serial killer who’s menacingly breathing into the mouthpiece. While Apple’s upcoming Liquid Glass refresh in iOS 26 is likely to be the most immediately noticeable aspect of the software update as it starts rolling out to the public on September 15, I believe a smaller addition in iOS 26 might even have a bigger impact on h
