The Best Colored Noise for Sleep (2025)

wired.com Julia Forbes 2025-12-05 21:12:40

As a certified sleep science coach and mattress tester of five years, I'm no stranger to soothing noises being part of many people's sleep hygiene arsenal. For some, the perfect soundtrack might be white noise. For others, it could be a different color entirely—sometimes streamed on their phone, but often courtesy of a sound machine. If your sound machine or app offers a variety of different colored sounds, how might you know what they mean, or which might be best for your brain? How Noise Is “

As pizza's popularity spreads around the world, a group of top-secret agents are travelling the globe on espionage missions to determine what "real" pizza is.

SpaceX is building a water pipeline to Starbase — but access comes with some conditions

The newest piece of infrastructure coming to Starbase, Texas, isn’t a launch mount or a booster. It’s a water pipeline, and who can hook up a tap (and on what terms) will shape the definition of “company town.” The new line, which will stretch from Brownsville to the newly incorporated city of Starbase, will replace the truck-hauled deliveries SpaceX has used to transport potable water for its employees and on-site residents.

Tesla’s Biggest Rivals Warn the EV Party Might Be Over

It’s going to be tough, and it’s going to be uncertain. That was the clear message from Rivian and Lucid, America’s two most promising electric vehicle manufacturers, as they gave a grim forecast for the future of the EV market. After a brief sugar rush of sales, Tesla’s top rivals are bracing for a brutal hangover, hit by a double punch of hostile policies from the second Trump administration: crippling tariffs and the fast-approaching end of the federal EV tax credits that have propped up the

The PS5 might be lacking the cadence of first-party exclusives that made its predecessor so successful, but that doesn’t appear to be slowing it down. Sony has announced that the console had shifted just north of 80 million units as of June 30, 2025.

Daring New Plan Lays Out Mission to a Black Hole

Fifty-six years after Disney filmmakers imagined what it would be like for a spacecraft crew to journey to a black hole in the 1979 movie The Black Hole, an astrophysicist has released a plan for a real interstellar mission to go where no spacecraft has gone before. Outlined in a new paper published today in iScience, the proposal is a two-pronged, surprisingly simple approach. First, scientists need to find a black hole that’s relatively nearby.

NASA Told to Overhaul Its Plans to Replace the International Space Station

gizmodo.com Passant Rabie 2025-12-07 02:27:23

For nearly 30 years, the International Space Station has played orbital home for astronauts from all over the world, but its time is running out. Slated to retire in 2030, NASA is aiming to replace it with a privately-run station that can host its astronauts in space when needed. And now under pressure to get a new station up and running fast and within a slashed budget, NASA’s current head—U.S. Transportation Secretary Sean Duffy—is completely overhauling the agency’s plans to replace the ISS.

Debounce

news.ycombinator.com Unknown 2025-12-05 00:04:13

Debouncing, in the context of programming, means to discard operations that occur too close together during a specific interval, and consolidate them into a single invocation. Debouncing is very similar to throttling. The key difference is that throttling enforces limits on continuous operations, while debouncing waits for invocations to stop for a specific time to consolidate many noisy invocations into one single invocation. A typical use case of debouncing is when responding to user input.
