The Sagrada Família takes its final shape

Instead, he focussed on a much different project: a basilica that was to rise on the outskirts of the burgeoning city. He wasn’t the project’s original architect—a more conventional designer, Francisco de Paula del Villar, had quit after a budget dispute. Gaudí pushed the plans in a radical direction. The world, he believed, had seen enough ogival windows and flying buttresses on cathedrals. “Let us have architecture without archeology,” he proclaimed. The project eventually became Gaudí’s sole

Leatherman (vagabond)

American vagabond of unknown and disputed identity The Leatherman ( c. 1839–1889) was a vagabond famous for his handmade leather suit of clothes who traveled through the northeastern United States on a regular circuit between the Connecticut River and the Hudson River from roughly 1857 to 1889. Of unknown origin, he was thought to be French-Canadian because of his fluency in the French language, his "broken English", and the French-language prayer book found on his person after his death. His i

Nostr

There are many problems with Mastodon, mostly due to the fact that it doesn't rely on any cryptography. Because it cannot do the multi-master approach of Nostr due to lack of cryptography, identities are assumed to be "owned" by the server, which is fully trusted by its tenants. Mastodon server owners can do all the harm centralized platforms can do to their underlings, which are completely helpless in case of misbehavior or even in the normal case where a server owner loses their server or deci

Nothing’s charging case ‘Super Mic’ is a small upgrade to earbud audio

The microphones in your earbuds probably suck. You know it, I know it, and apparently Nothing knows it too. Its fix? Better microphones — but in the charging case, not the buds. The Ear 3 buds feature what the company calls “Super Mic.” What that really means is a pair of microphones built into the earbuds’ case, with a button to activate those mics instead of the ones built into the buds. Nothing’s pitch is that the beamforming microphones in the case can deliver clearer audio and better nois

Live and work by lists? I found two genius apps that make them even easier to create

How often do you find yourself copying text from a website, document, or email that you want to add to a list app? That happens quite a bit to me. Something I read might inspire an idea for a book, and I want to make sure

Have a lot of stuff to track? My 5 favorite home inventory apps can help

HomePixel/iStock/Getty Images Plus Follow ZDNET: Add us as a preferred source on Google. I like to think I'm organized, but I could use a bit of help on this front, especially when it comes to keeping track of my things. For example, I have a large vinyl collection, and I couldn't tell you every album I own. However, with the help of a home inventory app, that task is considerably easier. With an inventory app, you can keep track of anything: food, clothing, tools, games, technology, kitchen

Luma AI created an AI video model that 'reasons' - what it does differently

AI developers are pushing video models onto creative industries. Some tools are positioned as automated creative partners. Just a few years ago, AI-generated video clips were a laughing stock on the internet -- anyone remember the nightmarish video of AI-generated Will Smith wolfing down spaghetti? The technol

Classic recessive-or-dominant gene dynamics may not be so simple

In brief A new Stanford study explores how fruit fly populations maintain genetic diversity amid changing environments, which is crucial for survival against future challenges. The research provides direct evidence to support the theory of “dominance reversal” in genetics. Findings indicate that genetic variants can act as dominant or recessive based on environmental conditions – which gives the flies long-term pesticide resistance. Populations live in rapidly changing environments – droughts

OpenTelemetry collector: What it is, when you need it, and when you don't

Do you really need an OpenTelemetry Collector? If you're just sprinkling SDKs into a side project - maybe not. If you're running a multi-service production environment and care about cost, performance, security boundaries, or intelligent processing - yes, you almost certainly do. This post explains exactly what the OpenTelemetry Collector is, why it exists, how data flows with and without it, and the trade‑offs of each approach. You’ll leave with a decision framework, deployment patterns, and p

Rules for creating good-looking user interfaces, from a developer

Creating good-looking user interfaces has always been a struggle for me. If you’re in the same camp, this might help. I recently redesigned Lighthouse, and during that process built a system that helped me create much better designs than I ever did before. This system is about achieving the best possible design with the least amount of effort. There’s no need to know about the psychological impact of colors, which fonts are best for which purpose, golden ratios, etc. This is expert-level desig

The Math of Catastrophe

In the 1960s, the Soviet climatologist and mathematician Mikhail Budyko set out to investigate the potential future of a planet on the brink of nuclear Armageddon. He started by looking some 600 million years into the past. Back then, some scientists claimed, the ancient planet was an iced-over snowball. Most researchers considered that a crackpot theory. Ice over the equator? Please. But Budkyo developed a mathematical model to back it up. If sea ice had been able to expand past a critical lat

The Rise and Fall of the British Detective Novel (2010)

Between around 1910 and 1950, England was in the grip of a genteel crime wave; a seemingly endless output of murder mysteries, generally set among the upper and upper middle classes and usually solved by a brilliant amateur detective rather than by the police. They were read enthusiastically and with an insatiable appetite by British middle-class readers. The ‘golden age’ of the English detective story during this span of 40 years or so is an important and often overlooked feature of English pop

David Lynch LA House

David Lynch, the visionary American filmmaker behind Twin Peaks, Blue Velvet and Mulholland Dr, passed away this January, yet his creative universe endures in objects, spaces and ideas. Among the most striking of these relics is his larger-than-life, meticulously designed Hollywood Hills home; a cinematic setting in its own right. Perched on a sweeping 2.3-acre hillside, David Lynch’s private compound, which is now listed for $15 million by Marc Silver of The Agency, unfolds like one of his own

Best Robot Lawn Mowers: After Testing Mowers for Weeks I Discovered the 4 Worth Buying

Robot lawn mowers of yore started off using a boundary wire to determine where it could and could not go, and they were problematic. The boundary wire had to make a complete, unbroken circle. And if anything happened to the wire, you had problems. These days, robot mowers work via GPS, but it's GPS with a little bit extra in an RTK beacon. Scott Porteous, head of robotics for Husqvarna broke it down for me. Adam Doud/CNET GPS navigation GPS today is accurate down to a few feet. That's fine wh

Your Pixel 10 Might Have Issues With Older Wireless Chargers

When Google introduced the Pixel 10 lineup in August, it became one of the first major Android phones to receive the Qi 2 wireless charging standard, which Google calls Pixelsnap. However, almost immediately after the Pixel 10's release, people noticed issues with its wireless charging. Some people are having trouble charging their phone with the new Pixelsnap charger, and others are having issues with older wireless chargers, including Google's own Pixel Stands. The bulk of the problems happen

Two UK teens charged in connection to Scattered Spider ransomware attacks

Federal prosecutors charged a UK teenager with conspiracy to commit computer fraud and other crimes in connection with the network intrusions of 47 US companies that generated more than $115 million in ransomware payments over a three-year span. A criminal complaint unsealed on Thursday (PDF) said that Thalha Jubair, 19, of London, was part of Scattered Spider, the name of an English-language-speaking group that has breached the networks of scores of companies worldwide. After obtaining data, t

Vaccine Panel Stacked by RFK Jr. Recommends Delaying MMRV Immunization

A federal vaccine advisory committee made up of members hand-picked by Health and Human Services secretary Robert F. Kennedy Jr. recommended in an 8-3 vote on Thursday that the combined measles, mumps, rubella, and varicella (MMRV) vaccine should not be given before age 4, citing long-known evidence that shows a slightly increased risk for febrile seizures in that age group. Experts say that while frightening, febrile seizures—which are uncommon after vaccination—are usually short-lived and har
