Mysterious Object From Beyond Solar System May Be "Seed" Traveling Galaxy and Creating New Planets, Paper Finds

futurism.com Unknown 2025-09-19 02:03:59

Astronomers have been fascinated after spotting an object earlier this year that came from interstellar space as is now hurtling through our inner solar system. Since then, they've been using powerful telescopes to study the mysterious object, trying to understand its unusual composition and exact origins. Most agree that it's probably a comet, albeit an unusual one, though at least one has posited that it could be a remnant of an advanced extraterrestrial civilization — a colorful claim, but o

Page Object (2013)

news.ycombinator.com Martin Fowler 2025-09-23 02:26:19

When you write tests against a web page, you need to refer to elements within that web page in order to click links and determine what's displayed. However, if you write tests that manipulate the HTML elements directly your tests will be brittle to changes in the UI. A page object wraps an HTML page, or fragment, with an application-specific API, allowing you to manipulate page elements without digging around in the HTML. The basic rule of thumb for a page object is that it should allow a softw

This horse-themed browser puzzle game is an absolute delight and I can't stop playing it

Another day, another adorable game that I've become completely obsessed with. I came across Roly-Pony this weekend during a particularly soul-sucking bout of doomscrolling, and it's turned out to be the perfect little temporary respite from the horrors. (Shoutout to Alice Ruppert of The Mane Quest for always keeping us informed about the latest in horse games).

Rasterizer: A GPU-accelerated 2D vector graphics engine in ~4k LOC

Rasterizer Inspired by my love of Adobe Flash, I started to work on a GPU-accelerated 2D vector graphics engine for the original iPhone, and then the Mac. Three iterations, and many years later, I have finally released Rasterizer . It is up to 60x faster than the CPU, making it ideal for vector animated UI (press the T key in the demo app to see an example). The 10-year gestation was the result of endlessly iterating over the core problem of efficiently turning vector paths into reference-qual

AR Fluid Simulation Demo

Fluid Simulation (Demo) 2025 I wanted to see what happens when a fluid simulation collides with real objects. To test this idea I created this demo. To capture the shapes of objects, I mounted a webcam above the screen. A polarization filter blocks the image displayed on the screen, preventing a feedback loop, while still allowing the camera to see anything placed in front of it. The video feed is then aligned with the computer-generated simulation, so the fluid can react to those cutout obj

Data, objects, and how we're railroaded into poor design (2018)

news.ycombinator.com Unknown 2025-11-04 15:06:05

I don’t think we have any actually good programming languages, and I don’t think I’m alone in believing this. Programming is hard, and language design is harder. We’re still learning. But I think they’re all failing us in a shockingly fundamental way. The root of the trouble is a distinction I’d like to draw between data and objects. Let me know if you think there are better terms to use. Programming languages give us tools to represent things. Sometimes these things are values: the integer 1.

James Webb Finds Evidence of Free-Floating Planets So Large They Can Gather Their Own Planetary Systems

futurism.com Unknown 2025-11-25 18:30:04

So much for heliocentrism. An international team of astronomers using observations made with the James Webb Space Telescope have found evidence of massive planets out there that're capable of forming their own planetary systems — without a star. These planets would be the center of something like a mini version of our solar system where other, smaller planets revolve around it. But without the light of a star, these systems, if they exist, would go largely overlooked by our telescopes, lost to

If the lineages are followed back beyond the origin of life on Earth to the origin of the universe, it would be logical to assume that the memory of the universe was lower in the past, which means that the universe's ability to generate objects of high Assembly is limited by its size in time. Some objects are too large in time to come into existence in intervals that are smaller than their assembly index. For complex objects such as computers to exist in our universe, many other objects had to f

I mean, it sounds great for summer—just like a blanket that warms you up but in reverse. Sadly, these products don’t do what they claim.
