Forget the Crypto Bros. Wall Street Is Driving the New Crypto Boom

gizmodo.com Luc Olinga 2025-11-25 18:38:24

The crypto market is on fire again, but this time, the fuel isn’t coming from “crypto bros” on social media. It’s coming from Wall Street, and it’s all based on a massive bet that the Federal Reserve is about to cut interest rates. Ether, the second-largest cryptocurrency, is leading the charge, surging nearly 10% in the past 24 hours to $4,723.26, bringing its all-time high of $4,878.26 within sight.

Flowers of Fealty: Commemoration of the Christening of Elisabeth of Hesse (1598)

One suspects these botanical additions were meant to stage a conversation with the original manuscript. A dedicatory Latin poem wishes the princess happiness and that she continue “growing for a long time like a little blossom”, while the accompanying watercolor marginalia shows various flowers in full spring bloom. On the next page, the poem envisions the princess’s honorable name “flourishing” in the land and bringing forth flowers — verse that is framed by racemes of asphodels. There are text

5 Best Electric Toothbrushes, Backed by Dentists and Hygienists

wired.com Boutayna Chokrane 2025-12-02 00:30:00

What About U-Shaped Toothbrushes? There are many U-shaped toothbrushes available now that use a mouthpiece full of bristles to brush one section of teeth—or sometimes the entire mouth—all at once in around 30 seconds. We've tried a few and think they're fine to use in addition to regular brushing. None of them are as effective as standard electric toothbrushes. Bill Busch of North Kansas City Dental and Joseph Salim, owner of Sutton Place Dental Associates, agree that these aren't replacements.

AI Ethics is being narrowed on purpose, like privacy was

A few days ago, OpenAI released an open-source language model for the first time in a very long time. It had been promised for a while, but the deadline kept being pushed for “safety” concerns. In fact, they’ve put quite a bit of time and effort into discussing safety, because, ostensibly, safety and ethics is at the top of people’s minds. So, the public is worried about AI ethics, and OpenAI is putting efforts into making sure the AI is ethical. Sounds like a match. Not just a match, but a

If you're dealing with jaw, tooth, ear or head pain, especially in the morning, you may have sleep bruxism, which means you're grinding or clenching your teeth when you sleep.

Software is a creative endeavor and a craft. And like any creative endeavor and any craft, it is subject to fashions. About a decade ago, one of those fashions was Hexagonal Rails largely inspired by the DDD book, but also by the original Hexagonal Architecture work by Dr. Cockburn. Some of these applications are now up for their Rails upgrade and an “oil change,” and it’s interesting to see them in the wild and how they get perceived through the lens of the years that have gone by since then.
