How to Sit Properly at a Desk AccordionItemContainerButton LargeChevron It's not just about finding a chair you like. We've rounded up several tips on how to set up your desk properly here, but here are a few highlights. Sitting for too long in a day is not good for your health, no matter what chair you use. It increases the risk of type 2 diabetes, stroke, and heart disease. The best thing you can do is get up and move every half hour. If you can, a 40-minute walk per day can, according to a re

Handwave lends a hand to retailers with its European alternative to Amazon’s palm payments

Paying with a handwave once sounded like science fiction, but contactless palm recognition service Amazon One has already been used more than 8 million times, according to the company. That’s Amazon, though, which explains why it has been deployed in Amazon stores and more than 500 Whole Foods Market stores in the U.S., but only 150 third-party locations. Meanwhile, fintech startups like Latvia’s Handwave are stepping onto the field, aiming to provide third-party retailers with a similar but in

Why the best-value robot vacuum right now isn't made by iRobot or Shark

Mova P50 Pro Ultra ZDNET's key takeaways The Mova P50 Pro Ultra is available for only $799, down $200 from its regular price. This is one of the strongest robot vacuums on the market with 19,000Pa of suction, with reliable edge cleaning, mop removal, and obstacle avoidance.

Telephone colophon: Or, how I overengineered my call audio (2020)

Toward the beginning of the pandemic, a friend asked me how she could use an external vocal mic and a guitar with a pickup on Zoom calls. Sounds easy, right? But to have the amount of control a musician really wants, it turned out to be a bit more involved. Plus, when working from home for a microphone company, it’s pretty common to use a decent mic in meetings. This post explains the setup I’ve been using for my calls. (Don’t let the speakers fool you. Use headphones or it’ll feed back when

It closed at $115.50 and a $47 billion market cap, Yahoo Finance reports. The company and existing investors sold shares at the IPO price of $33 per share. Quite the pop. And after-market trading i

Enterprises prefer Anthropic’s AI models over anyone else’s, including OpenAI’s

Someone Gave ChatGPT $100 and Let It Trade Stocks for a Month

With $100 and a dream, one enterprising Redditor turned ChatGPT into a day trader, and the results so far have been pretty remarkable. In a post on r/Dataisbeautiful, the Redditor in question — real name Nathan Smith — described his project as a "6-month experiment to see how a language model performs in picking small, [under-covered] stocks with only a $100 budget." According to a chart shared on Reddit, this literal gamble is already paying off. Using GPT-4o, one of OpenAI's most advanced mo

Your public ChatGPT queries are getting indexed by Google and other search engines

It’s a strange glimpse into the human mind: If you filter search results on Google, Bing, and other search engines to only include URLs from the domain “https://chatgpt.com/share,” you can find strangers’ conversations with ChatGPT. Sometimes, these shared conversation links are pretty dull — people ask for help renovating their bathroom, understanding astrophysics, and finding recipe ideas. In another case, one user asks ChatGPT to rewrite their resume for a particular job application (judgin

Meta faces antitrust investigation over AI chatbot integration in WhatsApp

In brief: Meta began integrating its AI chatbot into WhatsApp in 2024, offering users easy access to its large language model service.

The Italian Competition Authority (AGCM) recently launched an antitrust investigation into Meta AI's integration within WhatsApp. In March 2025, Meta began pre-installing its AI chatbot in the messaging app, which

The Download: a 30-year old baby, and OpenAI’s push into colleges

Google's 'virtual satellite' AI model can provide a near real-time view of Earth

Google has introduced a new AI model called AlphaEarth Foundations that it says can function like a "virtual satellite." The model uses a system called "embedding," which works by taking big volumes of pubic information from various sources every day, such as optical satellites, radars and climate simulations, and then combining them all together. It then divides lands and coastal waters into 10x10 meter squares, which it then analyzes and tracks over time. As Wired explains, these squares are c
