The Prime Reasons to Avoid Amazon

Amazon’s now-legendary “Prime Day” is July 8-11. Much like Black Friday or Cyber Monday, this means sales on lots of items on Amazon’s vast marketplace, and as such many people flock to the giant’s website to get sweet deals on everything from computers to small kitchen appliances and more. While many of us are feeling the financial crunch more than ever, I urge you, dear reader, to resist the allure. I don’t typically have strong opinions about where people chose to shop or how they decide to s

So Long, ‘Anthem,’ See Ya In the Skies

In February 2019, Dragon Age and Mass Effect developer BioWare released Anthem, a third-person shooter about human Freelancers donning armored Javelin suits to fight monsters and various factions. After seven years, EA is permanently taking the live-service game down on January 12, 2026, and with it, a chapter in the studio’s modern era is forever gone. To know Anthem is to know its tumultuous life; the game famously suffered from crunch and internal struggles owing to BioWare’s knowledge of se

Mysterious Object Headed Into Our Solar System Is Coming From the Center of the Galaxy

Folks, it's official: the object that astronomers recently spotted blowing through the outer solar system came from interstellar space. Yesterday, the intriguing stranger was named A11pl3Z. Now, it's earned the esteemed designation 3I/ATLAS — that "I" standing for "interstellar." 3I/ATLAS is currently located between the orbits of the asteroid belt and Jupiter, the New York Times reports, where it's about 416 million miles away from the Sun, NASA said. That's equal to four and a half times the

Problems the AI industry is not addressing adequately

I think the AI industry is facing a handful of urgent problems it’s not addressing adequately. I believe everything I write here is at least directionally true, but I could be wrong. My aim isn’t to be definitive, just to spark a conversation. What follows is a set of expanded thoughts on those problems, in no particular order.

I Found Out Ring and Nextdoor's Rules on Posting About ICE Raids, Police and More

In a surprise trend of the year, a growing number of communities are using apps like Ring Neighbors and Nextdoor to discuss and track ICE immigration raids. These security apps and associated security cams and video doorbells weren't exactly intended to follow federal agents, but it's proven to be a popular effort in areas like California. While law enforcement retains the ability to request home security videos with a warrant, they aren't used to being on the receiving end of this technology.

Congress Won't Block State AI Regulations. Here's What That Means for Consumers

After months of debate, a plan in Congress to block states from regulating artificial intelligence was pulled from the big federal budget bill this week. The proposed 10-year moratorium would have prevented states from enforcing rules and laws on AI if the state accepted federal funding for broadband access. The issue exposed divides among technology experts and politicians, with some Senate Republicans joining Democrats in opposing the move. The Senate eventually voted 99-1 to remove the propo

Is It Time to Stop Protecting the Grizzly Bear?

This story originally appeared on Vox and is part of the Climate Desk collaboration. In the early 1900s, long before smartphones and selfie sticks, tourists flocked to Yellowstone National Park—not for the geysers or scenery, but for a grotesque show: a nightly spectacle of grizzly bears raiding cafeteria scraps from open-pit landfills like desperate, starving pirates. The bears were in dangerous proximity to humans: Hungry bears tore at open car windows. Tourists posed a little too close with

Log your weight in Apple Health quickly and cheaply with this iPhone-compatible smart scale

After my last WiFi-enabled smart scale broke and refused to connect to the Internet anymore, I sought something simpler and cheaper to replace it. The old scale had all sorts of fancy service integrations that I never used. I just wanted something that would track my weight and report the measurements to the Health app on my iPhone. The Eufy C20 smart scale is what I landed on and I’m very happy with it — and it’s pretty cheap too. Here’s how it works … Firstly, the scale works completely inde

In this post I'm going to argue, based on historical trends of Bitcoin-related posts on Hacker News, t

You Probably Own These 20 Kitchen Tools -- And Pros Think They're Useless

The ITTAGE indirect branch predictor

While investigating the performance of the new Python 3.14 tail-calling interpreter, I learned (via this very informative comment from Sam Gross) new (to me) piece of performance trivia: Modern CPUs mostly no longer struggle to predict the bytecode-dispatch indirect jump inside a “conventional” bytecode interpreter loop. In steady-state, assuming the bytecode itself is reasonable stable, modern CPUs achieve very high accuracy predicting the dispatch, even for “vanilla” while / switch -style inte

A rare look inside the durability lab where Apple tortures its products

Apple puts its products through a lot of tests during the development process, intended to ensure they have a long and reliable life even in challenging conditions. The company tests at least 10,000 iPhones prior to launch in an attempt to cover all the bases. It’s not often the iPhone maker lets outsiders into its labs, but Apple invited some of those attending WWDC 2025 to visit one to see for themselves the conditions it expects its gadgets to survive … To be clear, it’s not the first time
