Bitrig lets anyone build at this level of polish. If you've thought about making an iPhone app, Bitrig is the easiest possible way to

This Giant Sphere Just Joined the Hunt for ‘Ghost Particles’

The elusive neutrino—a near massless particle with no charge—tests the limits of physicists’ creativity, but sometimes the answer is just to go big. And the biggest detector of them all has finally joined the search for the so-called “ghost particles.” After a decade of construction, China’s Jiangmen Underground Neutrino Observatory (JUNO) officially began taking data on August 26. The giant, spherical detector lies about 2,300 feet (700 meters) underground and collects antineutrino signals fro

South Korea bans smartphones in all middle and elementary school classrooms

South Korean lawmakers have banned smartphones and other smart devices in elementary and middle school classrooms, The New York Times reports. The law goes into effect in 2026. The legislation only outlaws these devices during class hours and there are no stipulations regarding punishment for violators. The law does, however, give principals and teachers the power to stop students from carrying or using a phone on school grounds. Additionally, students are able to use smart devices during emerg

We Rebuilt Cloud Life's Infrastructure Delivery with System Initiative

By Ryan Ryke, CEO, Cloud Life ‍ This is the story of how we eliminated static configuration files from our infrastructure workflows at Cloud Life, and, in the process, cut delivery times by more than half, improved reliability, and made our engineers’ work feel much smoother and more manageable. Before this project, we’d been working with the same model that most modern infrastructure teams use: Terraform scripts, config repos, PR reviews, CI pipelines. We’d optimized what we could, but the w

Intel details everything that could go wrong with US taking a 10% stake

Some investors are not happy that Intel agreed to sell the US a 10 percent stake in the company after Donald Trump attacked Intel CEO Lip-Bu Tan with a demand to resign. After Intel accepted the deal at a meeting with the president, it alarmed some investors when Trump boasted that his pressure campaign worked, claiming Tan "walked in wanting to keep his job, and he ended up giving us $10 billion for the United States." "It sets a bad precedent if the president can just take 10 percent of a co

The Trump administration promised a fourth wireless carrier — America got a hot mess instead

With Dish Network owner EchoStar selling $23 billion in valuable spectrum to AT&T, any pretense that the TV provider will become a serious wireless competitor is dead. But the project was always doomed to fail, and despite plenty of assurances by the Trump administration and other companies involved, the very obvious writing was always on the wall. More than 9,000 T-Mobile employees lost their jobs, the wireless sector stopped seriously competing on price, and T-Mobile increasingly began to beh

Disney sues Sling TV over its one-day cable passes

The lawsuit, filed under seal, claims Sling violated the terms of its licensing agreement with Disney and included its networks in the sh

This Galaxy Tab S11 Ultra leak teases how much faster it is over last year’s model

TL;DR A bevy of Galaxy Tab S11 Ultra renders have leaked. The leak includes promo materials that reveal a few of the tablet’s specs. One of the images states that there’s a 24% CPU, 27% GPU, and 33% NPU improvement compared to the tablet’s predecessor. Samsung announced the Galaxy Tab S10 Lite earlier this week, but we know two more tablets are on the way. While leaks are pointing to an early September announcement for the Galaxy Tab S11 and S11 Ultra, nothing has been officially confirmed. A

Computing’s Top 30: Theofanis Raptis

Transitioning between two different cultures and professional roles—from working at a university in Greece to joining the National Research Council of Italy—presented Theofanis Raptis with several valuable lessons, including an understanding of what he calls an intellectual “fermentation” process. Triggered by internationalization, bilateral cooperation, and cross-discipline collaborations, this fermentation included the dynamic exchange and blending of ideas across disciplines and cultures, le

Why zero trust is never 'done' and is an ever-evolving process

Picture this scenario: Six months after celebrating their "zero trust transformation," a financial services firm gets hit with a devastating breach. Attackers waltzed through a supply chain vulnerability in a third-party API, bypassing all those carefully configured identity controls . The firm ticked every checkbox and met every requirement - yet here they are, scrambling to contain customer data exposure. But wasn’t zero trust supposed to protect them? The truth is zero trust isn’t a project

The first stars may not have been as uniformly massive as we thought

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of stars to form the first planets. The first stars were initially composed of pure hydrogen and helium, and they were massive—hundreds to thousands of times the mass of the Sun and millions of times more luminous. Their short lives ended in enormous explosions called supernovae, so they had neither the

US sanctions fraud network used by North Korean ‘remote IT workers’ to seek jobs and steal money

The U.S. Treasury has sanctioned an international fraud network used by North Korea to infiltrate U.S. companies with hackers posing as legitimate job seekers, agency officials announced Wednesday. The sanctions are the latest action taken by the U.S. Treasury in recent months aimed at combating North Korean government workers from seeking employment at American companies using fake identities and documents to apply for jobs. Once employed, the hackers earn a wage from the company, but also ste

Poll: Have you ever traveled with your portable projector?

If it feels like you’ve seen more ads for pocket-, backpack-, and even can-sized projectors lately, you’re not imagining it. Once a novelty, small form beamers are carving out a solid place in the mainstream market. Part of the appeal is obvious: today’s portable projectors aren’t the dim, clunky boxes you may remember from your school library. Brands are cranking out units with higher resolutions (even 4K), laser and LED light sources, and wireless smarts that make setup simple. Meanwhile, aut

Chipolo launches new Loop and Card Bluetooth trackers

The new trackers are available for pre-order on the Chipolo website today. The Card tracker is thin enough to fit inside your wallet and has a speaker in the corner capable of reaching 110 dB, to ensure you can hear it easily. It comes in black and will retail for $39. The Loop is a small circular tag remini

The “Wow!” signal was likely from extraterrestrial source, and more powerful

A new study has re-examined the famous "Wow!" signal, finding that it likely has an extraterrestrial origin after all, and may have been even more intense than previously believed.

Slowing down programs is surprisingly useful

Most research on programming language performance asks a variation of a single question: how can we make some specific program faster? Sometimes we may even investigate how we can use less memory. This means a lot of research focuses solely on reducing the amount of resources needed to achieve some computational goal. So, why on earth might we be interested in slowing down programs then? Slowing Down Programs is Surprisingly Useful! Making programs slower can be useful to find race conditions

Object-oriented design patterns in C and kernel development

My scheduler operations implementation A benefit of working on your own operating system is that you’re free from the usual "restraints" of collaboration and real applications. That has always been a major factor in my interest in osdev. You don’t have to worry about releasing your program, or about critical security vulnerabilities, or about hundreds of people having to maintain your code. A benefit of working on your own operating system is that you’re free from the usual "restraints" of co

Experience smoother air travel with the new AirHelp app and AirHelp+ membership, and receive more money back for disruptions

Summer is known for being a very disruptive season, with strikes, severe weather, and overcrowded airports often leading to significant flight delays and cancellations. A smooth and fuss-free experience when flying can make all the difference to a trip; whether you’re taking the family on vacation or jetting between work appointments. What you don’t want are disruptions and delays that leave you stressed before you’ve even reached your destination, or worse, that delay you in getting to where y

Labor Day sales include a four-pack of Apple AirTags for $70

If you're thinking about getting some of Apple's AirTags, now's the time to act — Amazon currently has a four-pack on sale for $70. That's one of the lowest prices we've seen outside the big sales on Black Friday and Prime Day. For Apple users, AirTags offer some large advantages over rival trackers. The ultra-wideband functionality offers precise tracking with iPhones less than five years old, so you can narrow your search between a couch and love seat in the same room. Over larger distances,

Wahoo Kickr Run Review: a (Mostly) Screen-Free Treadmill

Ask any serious runner and they’ll tell you that treadmills are usually the bane of their existence. Alas, for folks who don’t live in Mediterranean climates, they’re a necessary winter evil that keeps us fitter in the off-season, but not necessarily happier. The no-frills design of the Wahoo Kickr Run, plus a magical mode that allows it to track your pace without touching a button, is what makes it the most real-pavement-seeming treadmill I have ever run on. I’m admittedly 20 pounds heavier th

This Visiting Interstellar Comet Just Keeps Getting Weirder

Ever since interstellar comet 3I/ATLAS whizzed into our cosmic neighborhood in July, astronomers have been racing to uncover its characteristics. Now that the powerful James Webb Space Telescope has taken a good look at this icy interloper, it seems to be weirder than anyone imagined. A preprint submitted to the Astrophysical Journal Letters for peer review on Monday, August 25, describes the first results from JWST’s survey of 3I/ATLAS. A team of astronomers observed the comet with the telesc

Retry Loop Retry

Retry Loop Retry Some time ago I lamented that I don’t know how to write a retry loop such that: it is syntactically obvious that the amount of retries is bounded, there’s no spurious extra sleep after the last attempt, the original error is reported if retrying fails, there’s no code duplication in the loop. https://matklad.github.io/2023/12/21/retry-loop.html To recap, we have fn action () E ! T { ... } fn is_transient_error (err: E) bool { ... } and we need to write fn action_with_r

Das Problem mit German Strings

German strings are everywhere I look. The impression I’ve gotten from working in the Rust Arrow/Datafusion ecosystem and related file formats for the last couple of months is that StringViews (the implementation of German strings in Arrow) are becoming, if they have not already, the canonical form of representing string columns at execution time. This is generally a good idea. German strings are a fantastic innovation rooted in simplicity that greatly improves most string processing use-cases i

Cascata delle Marmore

Waterfall in Umbria, Italy and tallest man-made waterfall in the world The Cascata delle Marmore (Italian: [kaˈskaːta delle ˈmarmore]) or Marmore Falls is a tiered, man-made waterfall in Italy, created by the Romans in 271 BC. At 165m (541 feet) tall, it is the largest man-made waterfall in the world.[1] It is located 7.7 km from Terni, in the region of Umbria.[2] History [ edit ] In ancient times, the Velino River fed a wetland in the Rieti Valley. In 271 BC, in order to reclaim the land (an
