Credit: Ultra Heaven In this post, I analyze nootropics ratings I gathered through a recommender system. Jump directly to What I learned if you don’t like caveats and methodology. The effectiveness of a nootropic varies a lot from one person to another (your mileage will vary). This is why I built a nootropic recommendation system Enter ratings on nootropics you’ve tried, and it will spit out nootropics liked by people with similar rating patterns. This was initially based on the 2016 SlateSta

Star Meets Stunning End by Exploding Twice

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in Nature Astronomy, researchers analyzed the centuries-old remains of supernova SNR 0509-67.5 with the European Southern Observatory’s Very Large Telescope, finding the first visual evidence of a star’s “double-detonation.” Most supernovae are the explosive result of massive stars collapsing when they exhaust their nuclear fuel. Others, though, come from white dwarfs, the ina

A ‘Cheap’ MacBook With an iPhone Chip Could Bring Battery Life Like We’ve Never Seen Before

There’s an Apple rumor going around that I can’t stop musing about. (No, it’s not about a foldable iPhone.) It’s for a low-cost 13-inch MacBook that could cost hundreds of dollars less than Apple’s current $999 13-inch M4 MacBook Air. Noted tech analyst and supply chain sleuth Ming-Chi Kuo of TF International Securities said on Sunday that Apple is working on a 13-inch laptop powered by an A18 Pro chip. The tech blogosphere immediately erupted with skepticism that Apple would use a chip that po

Microsoft laying off about 9,000 employees in latest round of cuts

Google Messages is hiding a useful text formatting feature from users

Edgar Cervantes / Android Authority TL;DR It turns out Google Messages supports text formatting, but currently, only the integrated Gemini chatbot can use it to format its own replies. The hidden feature uses Markdown syntax, as seen when the Gemini chatbot formats its own text with symbols like double asterisks for bolding. A full rollout may be challenging due to cross-platform compatibility needs, as text formatting isn’t a standard part of the RCS specification. Google Messages was a sim

Google quietly revamps Android’s permission dialogs for a sleeker design for some

Tushar Mehta / Android Authority TL;DR Google has redesigned the permissions dialogs that appear in Android. This change appears following the June Google Play system update when applied to the latest Android 16 QPR Beta 2.1. Google has dropped the older design in favor of slimmer buttons and better readability. Even though Google first released a beta for Android 16 last year, its biggest design change didn’t start rolling out until the final beta, just weeks before the final release. With

Soldier’s wrist purse discovered at Roman legionary camp

Sam Altman Slams Meta’s AI Talent Poaching: 'Missionaries Will Beat Mercenaries'

I Hated the Apple Intelligence Button on My iPhone 16. Here's How I Turned It Off for Good

I'm a long time Apple fan, and I was so excited to upgrade to an iPhone 16 last fall. After spending five years with my well-loved, but outdated iPhone 11, I was ready for all the usual perks: a better battery life, nicer cameras and, most exciting to me, a new Barbie pink color. But what I didn't expect is that one new addition would threaten to ruin my entire experience with my brand new phone. If you've upgraded from an older iPhone in the past few years, you might have been surprised to see

Xbox Elite Wireless Controller 2 Is Overkill for Most People, but Still Delivers an Epic Gaming Experience

The Xbox Elite Wireless Controller Series 2 (or Elite 2 for short) has arguably been the industry gold standard for a pro-level game controller for the past decade. Over the years dozens of competitors have cropped up, hoping to give Microsoft a run for its money. While the Elite 2 still isn't perfect, it still sets the bar high. What I like about the Xbox Elite Wireless Controller Series 2 One of the best things the Elite 2 has going for it is the layout -- it's almost identical to the standa

Grok 4 spotted ahead of launch with special coding features

Elon Musk-funded xAI is skipping Grok 3.5 and releasing Grok 4 after Independence Day in the United States, and it could be the best model from the company.

I tried Google Chrome’s new bottom URL bar on Android, and it’s a mess

Andy Walker / Android Authority Google Chrome on Android has finally caught up with the rest of civilization by bashing two rocks together to introduce a bottom URL bar. Users who have sought out the feature and found it on Firefox, Samsung Internet, and Microsoft Edge can now choose which address bar position they prefer on Google’s browser: the traditional top of the screen or the more convenient bottom-edge placement.
