Folks, we have the best π

In the past couple of months, I published a number of articles on recreational math. I did my best to keep them accessible and fun, but my goal was usually to shed light at deeper mathematical truths. For example, the discussion of 0.999… = 1 served as a springboard to highlight some of the subtler properties of real numbers and the different meanings of infinity. Today, I have no agenda. This article exists because I discovered a somewhat obscure paper that says something unexpected and cool.

DEXA Scan Deep Dive, With Insights From the Experts (2025)

Earlier this summer, I found myself lying flat on a padded table in Tucson, Arizona. A mechanical arm hovered above me, scanning my body from head to toe while I tried to remain still. Fifteen-ish minutes later, a clinician handed me a thick packet of results, which included details on bone density, lean muscle mass, body fat percentage, and color-coded visuals showing exactly where each of these metrics was located within my body. This was a DEXA scan, short for dual-energy x-ray absorptiometr

OCSP Service Has Reached End of Life

Today we turned off our Online Certificate Status Protocol (OCSP) service, as announced in December of last year. We stopped including OCSP URLs in our certificates more than 90 days ago, so all Let’s Encrypt certificates that contained OCSP URLs have now expired. Going forward, we will publish revocation information exclusively via Certificate Revocation Lists (CRLs). We ended support for OCSP primarily because it represents a considerable risk to privacy on the Internet. When someone visits a

Betty Crocker broke recipes by shrinking boxes

To add to the frustration, one Redditor pointed out that the brand may have “tinkered with the amount of leaveners in the mix itself. … When [the cake] first comes out of the oven, it looks like a more substantial amount of cake but then shrinks as it cools down.” (We reached out to Betty Crocker to verify any ingredient changes and have yet to receive a response.)

iPhone 17 vs iPhone 16? Here's How They Compare and Which One You Should Buy

Apple unveiled the iPhone 17 at its "awe dropping" event along with the super skinny iPhone Air and the powerful iPhone 17 Pro/17 Pro Max. You may be wondering whether to get the new shiny standard iPhone 17 or buy last year's iPhone 16 which is $100 less. To help with that decision, here's a breakdown of how the two handsets compare. The iPhone 17 starts at $829 (or $799 if you activate with a carrier), the same as the iPhone 16 when it came out -- with the caveat that the iPhone 17 starts wit

Users turn to chatbots for spiritual guidance

In Brief AI-powered chatbots play a growing role in spiritual life, according to a New York Times story that examines the popularity of religious chatbots and apps. The Times notes that an app called Bible Chat has been downloaded more than 30 million times, while another app, Hallow, reached the number one spot in Apple’s App Store last year. For the most part, these apps are supposed to point people to religious doctrine and scripture to answer their questions, although at least one website

Should you upgrade to an iPhone 17 Pro from last year's model? I am - here's why

Sabrina Ortiz/ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Apple just launched its iPhone 17 Pro. The new model includes some enticing upgrades. I have had the 16 Pro for one year, and might trade it in. While most people choose to wait several years before upgrading their iPhones, that's a bit more challenging for tech aficionados like myself. I really wanted to hold out on upgrading my daily driver, the iPhone 16 Pro, but after watching the launch e

EPA Seeks to Eliminate Critical PFAS Drinking Water Protections

The U.S. Environmental Protection Agency (EPA) announced it will no longer defend rules that protect people from unsafe levels of PFAS “forever chemicals” in drinking water, seeking to reverse legal protections put into place last year. In its motion filed in federal court yesterday, EPA asked the court to axe its determinations to regulate and enforceable standards for four PFAS chemicals – GenX, PFHxS, PFNA, and PFBS. Separately, EPA previously announced that it will seek to extend the compli

Scarlet turns Shakespeare into an animated fantasy epic

Well, I was wrong, and I did manage to make it to one last day at the Toronto International Film Festival. One of the movies I wanted to see the most this year was Scarlet, the latest from Mamoru Hosoda, whose most recent film was the metaverse fairy tale Belle. Whereas that film was a reimagining of Beauty and the Beast, Scarlet is a twist on Hamlet that’s full of bold, creative ideas. I mostly enjoyed it, but unfortunately it’s saddled with an ending that doesn’t really fit. I also managed to

Kodak's mini camera fits on your keyring and is smaller than an AirPods case

Kodak has shrunk a camera to fit onto a keyring, but it still manages to shoot both photo and video. It's hard not to compare the Kodak Charmera to the ubiquitous Labubu craze, considering the highly collectible nature of Reto Pro selling these officially licensed mini cameras as a single blind box for $29.99 or a full set of six for $179.94. The keyring cameras, which only weigh 30 grams, are already sold out on the Reto Pro website, but are expected to be restocked. The blind box can be unwra

The case against social media is stronger than you think

The Mob, 1935, by Carl Hoeckner 1. Introduction The philosopher Dan Williams recently published two pieces on social media— “Scapegoating the Algorithm” at Asterisk Magazine, and “The Case Against Social Media is Weaker Than You Think” at his Substack. As their titles attest to, both argue that the case against social media, on epistemic and political grounds, has been considerably overstated. I recently published a lengthy essay arguing the opposite: that the case against social media has, i

AMD’s RDNA4 GPU architecture

RDNA4 is AMD’s latest graphics-focused architecture, and fills out their RX 9000 line of discrete GPUs. AMD noted that creating a good gaming GPU requires understanding both current workloads, as well as taking into account what workloads might look like five years in the future. Thus AMD has been trying to improve efficiency across rasterization, compute, and raytracing. Machine learning has gained importance including in games, so AMD’s new GPU architecture caters to ML workloads as well. Fro

Two Slice, a font that's only 2px tall

Two Slice A font that's only 2px tall, and somewhat readable! Uppercase and lowercase have some different variants, in case you find one more readable than the other. Numbers (sort of) and some punctuation marks are included. You can probably read this, even if you wish you couldn't. It tends to be easier to read at smaller sizes.

Myocardial infarction may be an infectious disease

According to the recently published research, an infection may trigger myocardial infarction. Using a range of advanced methodologies, the research found that, in coronary artery disease, atherosclerotic plaques containing cholesterol may harbour a gelatinous, asymptomatic biofilm formed by bacteria over years or even decades. Dormant bacteria within the biofilm remain shielded from both the patient’s immune system and antibiotics because they cannot penetrate the biofilm matrix. A viral infect

Woman Sends Money to "Stranded Astronaut" So He Can "Buy Oxygen"

"In space on a spaceship right now." The sky's the limit for how outrageously implausible some scams can get. Actually, try beyond the atmosphere. An elderly woman in Japan sent thousands of dollars to a trickster who claimed to be an astronaut trapped in space and in danger of suffocating, Agence France-Presse reports. In fairness to the lady, though, she thought they were in love. The 80-year-old pensioner, who lives in Sapporo, the capital of Japan's northern island Hokkaido, met the scamm

California's age verification bill for app stores and operating systems takes another step forward

A California bill that would require operating system and app store providers to verify users' ages before they can download apps has cleared the Assembly 58-0, and will now move on to Gov. Gavin Newsom, Politico reports. The Digital Age Assurance Act (AB 1043), introduced by Assemblymember Buffy Wicks, does not require photo identification for verification, but puts the onus on the platforms to provide tools for parents to indicate the user's age during a device's setup, and use this informatio

Wimpy vs. McDonald's: The Battle of the Burgers

When the burger landed on the tables of the first Wimpy Bar in 1954, it marked a new era of modernity, global connection, and convenience for a Britain rebuilding from the austerity of the Second World War. But it later found itself at the heart of a cultural war against these same ideals. ‘The McDonalds are coming’, declared the Reading Post in March 1983 as Wimpy’s competitor gained ground on the British high street. ‘It looks like the battle of the burgers is about to erupt.’ As the first mo

Show HN: Vicinae – A native, Raycast-compatible launcher for Linux

California Lawmakers Once Again Challenge Newsom’s Tech Ties with AI Bill

Last year, California Governor Gavin Newsom vetoed a wildly popular (among the public) and wildly controversial (among tech companies) bill that would have established robust safety guidelines for the development and operation of artificial intelligence models. Now he’ll have a second shot—this time with at least part of the tech industry giving him the green light. On Saturday, California lawmakers passed Senate Bill 53, a landmark piece of legislation that would require AI companies to submit

Big Businesses Are Doing Carbon Dioxide Removal All Wrong

This story originally appeared on Grist and is part of the Climate Desk collaboration. Achieving net-zero greenhouse gas emissions by 2050 will require removing carbon dioxide from the atmosphere, according to the Intergovernmental Panel on Climate Change, the world’s foremost authority on the topic. But only some types of carbon removal are actually effective—and these are largely not the kind that major companies are investing in. A new report from the NewClimate Institute, a European think
