People Are Being Warned Not to Drink Coffee in the Heat. I Asked Experts if That's an Exaggeration

The summer has just begun, and many areas across the US are already experiencing sweltering temperatures. In response, NWS Las Vegas, the National Weather Service covering southern Nevada, northwestern Arizona, and southeastern California, posted an extreme heat warning graphic on X, cautioning residents not to drink caffeine because it speeds up dehydration, contributing to heat stroke and exhaustion. NWS Las Vegas's graphic soon made headlines, in which Americans were "warned not to drink cof

Show HN: Spegel, a Terminal Browser That Uses LLMs to Rewrite Webpages

Spegel - A Terminal Browser That Uses LLMs to Rewrite Webpages June 23, 2025 TL;DR Spegel is a proof-of-concept terminal web browser that feeds HTML through an LLM and renders the result as markdown directly in your terminal. Your browser does not support the video tag. Two weekends ago, after my family had gone to sleep, I found myself unsupervised with a laptop and an itch to build something interesting. A couple of hours later, I had a minimal web browser running in my terminal (no JavaSc

Researchers Uncover Hidden Ingredients Behind AI Creativity

We were once promised self-driving cars and robot maids. Instead, we’ve seen the rise of artificial intelligence systems that can beat us in chess, analyze huge reams of text and compose sonnets. This has been one of the great surprises of the modern era: physical tasks that are easy for humans turn out to be very difficult for robots, while algorithms are increasingly able to mimic our intellect. Another surprise that has long perplexed researchers is those algorithms’ knack for their own, str

Newark’s air traffic outages were just the tip of the iceberg

On June 2nd, US Transportation Secretary Sean Duffy traveled to Newark Liberty International Airport to celebrate the reopening of runway 4L-22R. This was unusual: few runway openings are glamorous enough to warrant a visit from the airport’s CEO, let alone a cabinet secretary. But as we reported last month, few airports have come to symbolize USDOT’s mismanagement of the air traffic control system as much as Newark. The ceremony and press conference was meant to transform Newark into a differe

Google’s answer to Apple’s Handoff is coming with a welcome upgrade for Android (Updated)

Rita El Khoury / Android Authority TL;DR Google is working on an Android-wide “Handoff” feature for multi-device syncing. This feature will enable access to apps and media across your devices, and even sync notifications between them. Apple has a similar Continuity feature called Handoff, albeit without notification syncing. Update, July 1, 2025 (04:46 AM ET): We’ve managed to enable the UI for the Handoff feature within Cross-device services. The feature is still a work in progress and doe

How proxy servers actually work, and why they're so valuable

Getty/sasha85ru Let's talk about proxy servers. Proxy servers are often confused with virtual private networks (VPNs) because their network architectures are very similar.

13 Best French Presses (2025): Plastic, Glass, Stainless Steel, Travel

The French press is an unassuming piece of coffee-making equipment. It doesn’t require electricity, yet experts agree that it can brew a richer and more full-bodied cup of joe in comparison with its more technologically advanced peers. For example, natural oils that would otherwise be filtered out in a drip coffee maker remain fully intact, making the coffee aromatic and robust. The French press method of making coffee is straightforward, cost-effective, easy to do, and hard to mess up. The dev

Jon Watts Left ‘Fantastic Four’ to Get His Groove Back

Before Matt Shakman took over directing duties for the MCU’s first Fantastic Four movie, Jon Watts was in charge. The director of the Spider-Man: Home trilogy dropped out in 2022, and his reasons for leaving are completely valid: he had to take a much-needed break. During a recent storytelling class at the Mediterrane Film Festival, Watts revealed he was basically “out of gas” by the time he was wrapping Spider-Man: No Way Home, which was shot in the early days of the pandemic. Following the nu

With ‘F1’, Apple finally has a theatrical hit

Looks like Apple has its first bona fide box office hit. The company has already produced critically-acclaimed and award-winning films for Apple TV+. In fact, while Netflix has reportedly spent millions on its Oscar campaigns, Apple’s “Coda” remains the only movie produced by a streaming service to win the Academy Award for Best Picture. It has, however, been a different story at the box office — at best, returns have fallen short of ambitious budgets, and with “Argylle,” the company had a spe

Sequence and first differences together list all positive numbers exactly once

EXAMPLE Sequence reads 1 3 7 12 18 26 35 45..., differences are 2 4 5, 6, 8, 9, 10 ... and the point is that every number not in the sequence itself appears among the differences.

At 20 years old, Reddit is defending its data and fighting AI with AI

Reddit CEO Steve Huffman stands on the floor of the New York Stock Exchange (NYSE) after ringing a bell on the floor setting the share price at $47 in its initial public offering (IPO) on March 21, 2024 in New York City. For 20 years, Reddit has pitched itself as "the front page of the internet." AI threatens to change that. As social media has changed over the past two decades with the shift to mobile and the more recent focus on short-form video, peers like MySpace, Digg and Flickr have fade

Tariff Impacts Are Real: I Found 13 Companies With Official Price Hikes

Higher prices for a lot of popular products seem inevitable on our current trajectory. James Martin/CNET In a lot of ways and for a lot of products in the US, the biggest impacts of President Donald Trump's aggressive tariff plans are still a ways off in the near future. Still, numerous companies have already hiked prices or said that they will be increased in the near future -- including, most recently, a popular and CNET-approved brand of smart lights. The fact of the matter is that tariffs

In a wild time for copyright law, the US Copyright Office has no leader

It’s a tumultuous time for copyright in the United States, with dozens of potentially economy-shaking AI copyright lawsuits winding through the courts. It’s also the most turbulent moment in the US Copyright Office’s history. Described as “sleepy” in the past, the Copyright Office has taken on new prominence during the AI boom, issuing key rulings about AI and copyright. It also hasn’t had a leader in more than a month. In May, Copyright Register Shira Perlmutter was abruptly fired by email by

Anker issues new global recall for five power bank models over fire hazard

Just days after issuing a voluntary recall for the Anker PowerCore 10000, the company has now issued a second, broader recall, this time with global reach and five additional power bank models affected. Anker says the move is a proactive step following recent improvements to its internal quality assurance systems. While the company claims the risk of malfunction is low, it’s recalling the affected models “out of an abundance of caution.” All five power banks flagged in the recall use lithium-io

SCOTUS upholds part of ACA that makes preventive care fully covered

The US Supreme Court on Friday upheld a key provision of the Affordable Care Act that requires health plans to fully cover many preventive health care services recommended by a federal panel. The ruling means that tens of millions of Americans can continue getting a variety of preventive services for free under their plans. Those cost-free services include an array of screenings, such as cancer screenings like mammograms and colonoscopies, as well as screens for obesity, lead exposure in childr

Cloudflare blocks largest DDoS attack - here's how to protect yourself

oxygen/Getty Cloudflare is a robust content delivery network (CDN) that specializes in providing protection against distributed denial of service (DDoS) attacks. Last month, Cloudflare blocked the largest DDoS attack in internet history. This assault peaked at a staggering 7.3 terabits per second (Tbps). That's a data deluge, equivalent to streaming nearly 10,000 high-definition movies in under a minute. The attack targeted an unnamed hosting provider using Cloudflare's Magic Transit DDoS pro

Apple shells out US$350M to acquire yet another office campus it was already leasing

It’s been a good week for Apple’s real estate team.

Transmitting data via ultrasound without any special equipment

Salesforce CEO says 50% of company work is now done by AI

What just happened? Not every company is slowing down its rush to go all-in on AI – Salesforce certainly isn't. According to CEO Marc Benioff, up to 50% of work being done at the software giant is now performed by AI. Benioff had plenty of praise for the technology, but said little about how it will impact those it puts out of work. Speaking in an interview on Bloomberg's The Circuit with Emily Chang, Benioff said "All of us have to get our head around this idea that AI could do things, that be

We’re learning more about what weight-loss drugs do to the body

We know they can suppress appetite, lower blood sugar, and lead to dramatic weight loss. We also know that they come with side effects, which can include nausea, diarrhea, and vomiting. But we are still learning about some of their other effects. On the one hand, these seemingly miraculous drugs appear to improve health in other ways, helping to protect against heart failure, kidney disease, and potentially even substance-use disorders, neurodegenerative diseases, and cancer. But on the other,
