New quantum paradox clarifies where our views of reality go wrong (2018)

That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a century is just what it’s telling us about what exists, what is real. There are myriad interpretations that offer their own take on the question, each requiring us to buy into certain as-yet-unverified claims — hence assumptions — about the nature of reality. Now, a new thought experiment is confro

YouTube Premium offers many more perks that I didn’t know I was paying for

Rita El Khoury / Android Authority I’ve been subscribed to YouTube Premium for many years now, and yet I didn’t know what I was exactly paying for. In my mind, I always associated Premium with an ad-free experience; being able to get rid of all those pesky long and interrupting ads before or while watching a video is alone worth the price. Adding the family benefits for my husband, and the fact that this works everywhere, including on our TVs, makes it more of a no-brainer. Even though I don’t

Here’s why everyone is using YouTube Music — even if they don’t love it!

Joe Maring / Android Authority Not many years ago, if you mentioned YouTube Music in a room full of long-time Google Play Music users, you could probably hear their collective sigh from space. Google retired its beloved service in 2020 and replaced it with something that, at the time, felt underbaked to be a true music player. Fast-forward to 2025, and while the groans haven’t completely died down, nearly everyone we know, including our readers, is using YouTube Music. This revelation came str

Remark raises $16M to build out human-powered expert models for e-commerce

Startups working on AI-powered e-commerce tools often rely on external data or user signals to build and improve their models. However, a company called Remark is taking a different approach by letting thousands of human experts chat with users while they are purchasing items, and then using that knowledge to train models. Remark also makes those experts “available” all the time by having their AI-powered persona answer questions. Remark said that this resulted in a 10% net revenue gain for par

Ask HN: 80s electronics book club; anyone remember this illustrator?

In the early 80's in the US, a popular DIY electronics magazine had a book of the month club that I loved. Most were small and leather bound hardback with topics like: make your own hydrophone; augmented reality (required a full room and a boom arm, sadly); an LCD model rocket launcher ignition; computer vision; lots and lots of robots. One book I remember (large, softcover, yellow cover) featured black and white, pen and ink illustrations of fantastically complex robots and machines. One that

This portable speaker delivers amazingly smooth sound with little distortion - and it's $130 off

Jack Wallen/ZDNET ZDNET's key takeaways The JBL Xtreme 4 Bluetooth speaker at Amazon for 34% off This football-sized speaker produces massive sound and really shines in the metal genre. It's a bit pricey, and the app only offers 3 EQ settings (none of which are customizable). Sometimes, you just need more power and volume than a typical Bluetooth speaker can provide.

Warner Bros. Gives Up on ‘Akira’ Remake, But Hollywood Won’t

Well, it’s happened. After 20 years of shuffling creative teams and development hell, Warner Bros. finally called it and won’t remake Akira. But things aren’t ending there, according to the Hollywood Reporter. WB’s simply let go of the movie rights it acquired back in 2002. They’ve now returned to the manga’s publisher, Kodansha; according to THR, several producers and talents are already “lining up” for the chance to adapt it.
