A polyglot's guide to multiple-dispatch (2016)

Where did the Smurfs get their hats

That white floppy hat on top of every Smurf’s head. What is it? Where did it come from? Do Smurfs have bald spots? We’ve got a history lesson coming up here, folks. Sit back. But, first, let’s answer a side question: What’s Under a Smurf’s Hat? There’s only one true source for information on this question, and that’s Peyo’s comics. Accept no substitutes. Yes, there are probably moments in various movies and cartoons where a Smurf can been seen without their hat on. That’s not Peyo. Peyo s

Elon Musk Says Starlink Could Replace Your Cellphone Carrier

On Wednesday, just one day after SpaceX acquired $17 billion of wireless spectrum from telecommunications company EchoStar, Elon Musk made some typically bold claims for how he would put it to use. The second-richest person in the world described a vision where Starlink could be your one-stop-shop for connectivity, whether at home or when you’re away from your Wi-Fi. On the All-In podcast, Musk said Starlink could eventually combine its home internet service with mobile. But he was careful to n

As Apple pursues AI, spare a thought for the poor HomePod

When the video kicking off Apple's "Awe dropping" event began yesterday, I was pleased to see a HomePod in the opening shot. I hadn't given any thought to Apple's beleaguered smart home speaker in ages, so I was all set for Tim Cook and crew to deliver an actual surprise and reveal new stuff for HomePod. When the entire presentation then passed without another peep about the product, I was disappointed, but resigned. HomePod has always been behind the curve. When smart speakers first came on th

Google Says the Open Web Is Now in "Rapid Decline"

In a major change in tune, Google has admitted that the "open web is already in rapid decline" — despite being adamant for months that the "web is thriving." As first spotted by The Verge, the tech giant attempted to dissuade regulators from breaking up its advertising tech business, arguing that doing so would harm publishers who rely on advertising revenue. Google argued that splitting up its ad business would "only accelerate" the open web's disintegration ahead of an antitrust trial in a D

NASA Found Signs of Ancient Alien Life on Mars. Here's How Excited You Should Be

NASA released a significant update from the Perseverance Mars rover on Wednesday, focusing on a particularly juicy tidbit for those watching from home: A small rock sample called Sapphire Canyon showed signs of potential biosignatures, or ancient alien life that may have once grown on Mars. That's possible because of the unique location where Perseverance located the sample in July 2024. It came from a rock named Cheyava Falls. This particular rock is in Jezero Crater, home to an ancient dry ri

Bronze Age Britons Threw Massive Ragers With Food and Friends From Far Away

You can learn a lot about people by studying their trash, including populations that lived thousands of years ago. In what the team calls the “largest study of its kind,” researchers applied this principle to Britain’s iconic middens, or giant prehistoric trash (excuse me, rubbish) piles. Their analysis revealed that at the end of the Bronze Age (2,300 to 800 BCE), people—and their animals—traveled from far to feast together. “At a time of climatic and economic instability, people in southern

OpenAI and Oracle reportedly ink historic cloud computing deal

In Brief Oracle sent its shares soaring after markets closed yesterday after reporting that it signed multiple multi-billion-dollar contracts with several customers.

James Gunn Teases What ‘Superman’ Follow-Up ‘Man of Tomorrow’ Will Be About

James Gunn fulfilled a dream today, calling his appearance on The Howard Stern Show “one of the greatest days of my life.” The interview with Stern covered many aspects of his career, including Superman, Peacemaker, the Guardians of the Galaxy movies, and his role as the co-head of DC Studios.

Perseverance Rover Finds Potential Sign of Ancient Life in Martian Rock

Today, NASA officials unveiled intriguing new findings from “Sapphire Canyon,” the 25th geological sample collected by the Perseverance Mars rover. This rock core has captivated scientists ever since Perseverance extracted it in July 2024, as it may help them determine if microbial life ever existed on the Red Planet. Now, NASA has revealed that the initial analysis of the Sapphire Canyon sample could not rule out a biological origin for its distinctive features. “This very well could be the cl

Pontevedra, Spain declares its entire urban area a "reduced traffic zone"

With the number of passenger vehicles rising across Europe, cities are grappling with air pollution, traffic accidents, and the loss of public space. In Spain, the city of Pontevedra has managed to overcome these challenges, surpassing national air quality standards and creating safer streets. The key, according to the Galician municipality’s mayor, is an urban model that prioritises residents over cars – without imposing an outright ban on private vehicles.

Some thoughts on personal Git hosting

As part of my ongoing (and somewhat futile) efforts to ReDeCentralise, I'm looking at moving my personal projects away from GitHub. I already have accounts with GitLab and CodeBerg - but both of those sites are run by someone else. While they're lovely now, there's nothing stopping them becoming as slow or AI-infested as GitHub. So I want to host my own Git instance for my personal projects. I'm experimenting with https://git.edent.tel/ It isn't quite self-hosted; I'm paying PikaPod €2/month t

AI vs. MAGA: Populists alarmed by Trump’s embrace of AI, Big Tech

Flanked by Silicon Valley’s most powerful executives in the White House last week, Melania Trump hailed artificial intelligence as potentially “the greatest engine of progress in the history of the United States of America.” Less than a mile from the first lady, in a hotel ballroom packed with MAGA faithful, top Republican Josh Hawley had a different message. AI “threatens the common man’s liberty” and could even undermine the Republic itself, the senior US senator from Missouri said. “The pr

This app just raised $14M to take on the loneliness epidemic

One Friday evening, Alyx van der Vorm couldn’t stop thinking, “I should do something with someone.” But she found herself alone once again on a Friday night, thinking about just heading to the gym. That was when she realized that trying to make plans with people these days is incredibly hard. “Figuring out who’s around, texting, waiting, researching options… It felt absurd that staying home and watching a movie was one tap, but seeing a friend was ten steps,” van der Vorm said.
