Show HN: I was curious about spherical helix, ended up making this visualization

Trying to understand how to move objects in 3D space MOVING OBJECTS IN 3D SPACE tap/click the right side of the screen to go forward → Have you ever wondered how to move objects along a spherical helix path? Okay… probably not, right? But one morning, this question popped into my head. It stuck with me long enough that I ended up diving into a few articles about it. From there, it spiraled into lots of explorations, trying to figure out how to move objects in 3D space. From a simple circ

This ‘Elio’ Deleted Scene Hints at an Alternate Version of the Movie

Pixar’s latest film, Elio, may not have been a box office success, but once it comes home, audiences are going to discover they missed something special. The story of a young boy who travels to space and is forced to save his planet by befriending a group of aliens is funny, exciting, and extremely heartfelt. Yes, it had a long trip to the finish line, but once it got there, it stuck the landing. Elio is coming to digital download on Tuesday, August 19, ahead of its physical release on Septembe

AT&T Promo Code: Get Up to $300 in August

Major wireless carriers: A necessary evil if you travel a lot, have a family, or are just interested in coverage that’s reliably consistent and widespread. AT&T is the third-largest provider in the US (first for 5G), with the largest coverage map. I’ve had various AT&T plans for more than a decade, first for just myself and now for my whole family, even though I only get one cell bar at my house and have to stand in one 5-square-foot patch of yard to make a phone call. And have lost entire days

Texas law gives grid operator power to disconnect data centers during crisis

Dive Brief: Data centers and other large, non-critical power consumers connected to the Electric Reliability Council of Texas transmission grid must accept curtailment during firm load shed events under a landmark law Republican Gov. Greg Abbott signed Friday. Senate Bill 6 pairs mandatory curtailment with a voluntary demand response procurement program under which loads of 75 MW or more could ramp down or switch to backup generation at utilities’ request.

The U.S. Department of Justice (DoJ) announced the seizure of more than $2.8 million in cryptocurrency from suspected ransomware operator Ianis Aleksandrovich Antropenko. Antropenko, indicted in Texas for computer fraud and money laundering, was linked to Zeppelin ransomware, a now-defunct extortion operation that ran between 2019 and 2022.

ChatGPT's Boss Says You Still Shouldn't Trust It as Your Main Source of Information

When you start a conversation with ChatGPT, you might notice some text at the bottom of the screen: "ChatGPT can make mistakes. Check important info." That's still the case with the new GPT-5 model, a senior OpenAI executive reiterated this week. "The thing, though, with reliability is that there's a strong discontinuity between very reliable and 100 percent reliable, in terms of the way that you conceive of the product," Nick Turley, head of ChatGPT at OpenAI, said on The Verge's Decoder podca

Acer Predator Helios 16S AI Review: Great Performance, Annoying Crashes

Keeping up with the intricacies of Acer’s Predator Helios gaming laptop line isn’t easy. The long-running series (dating back to 2017) now commands 12 different models, distinguished by screen size, the inclusion of AI acceleration (models with an “AI” suffix), and general affordability (denoted by the “Neo” suffix)—in every possible combination. Today, I’m reviewing the Predator Helios 16S AI, which boasts high-end specs and performance—especially in graphics-intensive tasks—but manages to kee

After a week that has seen the premier MMA promotion company ink a new multi-billion dollar TV deal, as well as firm up plans for an event at the White House, it's back to business in the Octagon this weekend, with UFC 319 offering up an intriguing middleweight title fight in Chicago. Saturday's main event sees South Africa's Dricus du Plessis aiming for a third successful title defense in a row as he takes on unbeaten Russian challenger Khamzat Chimaev. Du Plessis claimed the title with a win

The Folk Economics of Housing

Abstract Why is housing supply so severely restricted in US cities and suburbs? Urban economists offer two primary hypotheses: homeowner self-interest and political fragmentation. Homeowners, who outnumber and have organizational advantages over renters, are said to lobby against development to protect their property values. The fragmentation hypothesis emphasizes that development's negative externalities are borne locally while most of the benefits accrue regionally or nationally, leading local

Best Travel Headphones for 2025

Bose QuietComfort Ultra Earbuds: Bose has released its improved QC Ultra Earbuds (2nd gen), which means you'll be able to find discounts on the original QC Ultra Earbuds. They feature excellent sound and previously best-in-class noise-canceling performance.

TikTok’s new guidelines add subtle changes for LIVE creators, AI content, and more

TikTok is preparing an update to its Community Guidelines, which dictate the rules for participating on the social video platform as well as what standards the company uses to determine the videos that make it onto its For You feed. While the update largely rewrites the original text for simplicity’s sake, there are a few items that jump out in the new revision — notably how TikTok prioritizes its marketplace, how deeply it personalizes the experience per user, and a small change to the type of

I let LLMs write an Elixir NIF in C; it mostly worked

This post documents how I built a cross-platform Elixir NIF in C to get on-demand up-to-date disk-usage stats without relying on os_mon and its disksup service. I had Grok 3 generate the initial C code and Makefile, then iterated through multiple code reviews by Gemini 2.5 Flash and GPT-5 to make it work on Linux, macOS, Windows, and the BSDs (except DragonFlyBSD). Along the way, I ran into typical LLM hiccups that speak volumes about the breathless hyperbole often peddled by LLM vendors, comput

Great Myths #16: The Conflict Thesis

The “Conflict Thesis” forms a kind of underlying historial metamyth that informs and undergirds a substantial amount of historical assumptions by anti-theist polemicists. This is the assumed and unquestioned idea that Science and Religion have been perpetually at war down the ages. Also known as the Draper-White Thesis or Warfare Model, it is a conception of the history of science that presents religion as the perpetual and consistent enemy of science, technology and progress. It is a pervasive

Researchers at the University of California, Los Angeles, the Memorial Sloan Kettering Cancer Center in New York, and elsewhere are developing the vaccine, called ELI-002. In Phase I trial data released this week, people who received ELI-002 often developed an immune response t

Flowers of Fealty: Commemoration of the Christening of Elisabeth of Hesse (1598)

One suspects these botanical additions were meant to stage a conversation with the original manuscript. A dedicatory Latin poem wishes the princess happiness and that she continue “growing for a long time like a little blossom”, while the accompanying watercolor marginalia shows various flowers in full spring bloom. On the next page, the poem envisions the princess’s honorable name “flourishing” in the land and bringing forth flowers — verse that is framed by racemes of asphodels. There are text

Amazon Drone Beehive Concept (2019)

Transport is one of the main pillars of modern economies comprising a spectrum of individual systems and their interconnections that are intended to cover the mobility demand of people and goods. Transport systems include an extensive series of physical and organisational elements and are being characterised by an overall intrinsic complexity. These elements can be influencing each other directly and/or indirectly, linearly or nonlinearly, having also potential feedback cycles [1]. In particular

The Great American EV Tax Credit Rush Has Begun

The great EV buying frenzy has officially begun. In the last 48 hours, Tesla has seen delivery times for some of its most popular models skyrocket from a few weeks to nearly six months, a clear signal that consumers are stampeding to buy an electric vehicle before a crucial federal tax credit disappears for good. This is the short-term sales boom that experts have been predicting, a last-chance gold rush for buyers. But for the EV industry, it’s also a sugar rush that could lead to a brutal cra

Vanishing from Hyundai’s data network

The Yuppie Button page talks about making lots of light. Now I needed to do the opposite, by "going dark" -- to vanish completely from Hyundai's data network, and avoid having the car being tracked or actively interfered with outside of my control. See, this is one of the showstopping problems I have with Tesla -- they *insist* that you have your car online all the time, talking to Tesla's cloud and sending telematic data. Thank you, NO. The range of things that Hyundai's BlueLink setup is able
