A Collision With Another Planet Could Have Allowed for Life on Earth

wired.com Jorge Garay 2025-09-18 19:00:00

the Earth you walk on today might not be the same planet that was born 4.5 billion years ago. Many scientists believe that in its infancy, Earth collided with another world the size of Mars, and that instead of being destroyed, it was transformed, incorporating the mass of that foreign body to become the planet we know. Recent research adds another layer of relevance to that hypothesized cosmic event: Scientists believe that without that other body, the basic conditions for life to emerge on Ear

iOS 26: Here's How to Change Your iPhone's New Liquid Glass Design

Apple released iOS 26 on Monday, a few months after the company announced it at the Worldwide Developers Conference in June. The update introduces a handful of new features to your iPhone, like call screening, new ringtones and more. And the biggest change iOS 26 brings to your device is a new Liquid Glass design. Liquid Glass is the biggest visual update Apple has brought to your iPhone since the company released iOS 7 in 2013. The redesign makes menus and other visual elements appear transluc

iOS 26 officially launches today, but some developers aren’t sure it should

9to5mac.com Ben Lovejoy 2025-09-25 06:20:08

Today is the day that iOS 26 finally emerges from beta and is officially launched. The headline feature is of course the Liquid Glass look, which has proved almost as controversial as the minimalist look of iOS 7 back in 2013. Apple has made some pretty substantial changes to the look of the operating system after beta testers complained about poor legibility and confusing design elements. Even so, some developers are not at all convinced that Liquid Glass is ready to be unleashed … Wired’s Cr

The <template> HTML element serves as a mechanism for holding HTML fragments, which can either be used later via JavaScript or generated immediately into shadow DOM. This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨November 2015⁩.

The Joy of Mixing Custom Elements, Web Components, and Markdown

news.ycombinator.com Deane Barker 2025-11-23 16:16:56

The Joy of Mixing Custom Elements, Web Components, and Markdown I love Markdown. I write faster and more natively in it than any other format or tool. If we zoom way out, here’s the most basic philosophy of Markdown: replace complicated stuff with simpler stuff. That’s all it does, really. It replaces some tedious nested taggy stuff with way simpler stuff that makes more visual sense and is faster to type. At its core, Markdown is really just a bunch of macros.

Matrix Is Not Safe for EU Data Privacy

Matrix has long been promoted as the future of secure, decentralized communication. Backed by an open protocol, a vibrant developer community, and bridges to legacy systems, it promises interoperability and freedom from vendor lock-in. But when viewed through the lens of EU data privacy law, Matrix, and its commercial champion, Element, poses significant and underappreciated risks.

Generic interfaces

Generic interfaces Axel Wagner 7 July 2025 There is an idea that is not obvious until you hear about it for the first time: as interfaces are types themselves, they too can have type parameters. This idea proves to be surprisingly powerful when it comes to expressing constraints on generic functions and types. In this post, we’ll demonstrate it, by discussing the use of interfaces with type parameters in a couple of common scenarios. A simple tree set As a motivating example, assume we need

With macOS 26, Apple has announced a dramatically new look to their UI: Liquid Glass. Solid material icon elements give way to softer, shinier, glassier icons. The rounded rectangle became slightly more rounded, and Apple eliminated the ability for icon elements to extend beyond the icon rectangle (as seen in the current icons for GarageBand, Photo Booth, Dictionary, etc.). With this release being one of the most dramatic visual overhauls of macOS's design, I wanted to begin a collection chroni

That XOR Trick (2020)

There are a whole bunch of popular interview questions that can be solved in one of two ways: Either using common data structures and algorithms in a sensible manner, or by using some properties of XOR in a seemingly hard to understand way. While it seems unreasonable to expect the XOR solutions in interviews, it is quite fun to figure out how they work. As it turns out, they are all based on the same fundamental trick, which we will derive in a bottom-up way in this post. Afterwards we will lo

Linear algebra is typically explained using matrices. But matrix theory is just one possible perspective. Below, I describe an alternative approach to linear algebra. Tadeusz Banachiewicz (1882–1954), a Polish astronomer living in Krakow, was passionate about calculating machines. From the 1920s, Banachiewicz developed a method for computations on tables of numbers, which was particularly easy to perform with arithmometers. In honor of Krakow, Banachiewicz named these computational objects crac
