Joe Maring / Android Authority TL;DR YouTube is working on bringing comments to YouTube Music playlists. YouTube Music already allows comments on audio, video, and podcast content. If it succeeds, YouTube might also bring comments to video playlists on the main app. Two years ago, Google rolled out YouTube’s most hotly debated feature to YouTube Music. The comments section, which is both a treasure chest of insights and a bottomless pit of bullying remarks, is currently available for audio,

Ryan Haines / Android Authority TL;DR Google is working on adding a new section called “How was this made” to the details view. This section will tell a user if certain photos or videos were edited with AI or not. The feature uses Content Credentials to maintain a history of edits, both with and without AI tools. An error message will appear if the media history has been modified or is missing. As AI continues to blur the lines between what’s real and what’s fake, it’s becoming increasingly

Here’s how Google Find Hub satellite location sharing is going to work (APK teardown)

TL;DR Google announced back in May that the newly renamed Find Hub would be adding support for satellite-based location sharing. That’s still not here yet, but a recent app update reveals text strings that hint at how things will work. Users will be able to share their location once every 15 minutes, with a daily limit on maximum shares. Satellite support is changing the rules of the game when it comes to mobile connectivity, and we are still right now only in the early days of its evolution.

Dear String-to-Integer Parsers

news.ycombinator.com Sarah Muller 2025-11-25 20:44:32

These are very useful functions that any language with distinct string and integer types will include in their standard library. Pass in a string with decimal digits and it’ll return the equivalent in the binary integer form that you can do mathematics with. I’d like to make a modest proposal that I’d find very useful, and maybe you, dear reader, would too. “The rich man in his castle, the poor man at his gate. He made them, high or lowly, and ordered their estate.” Who me? Specifically, I’m

Previously called Saved, Google changed it into Activity earlier this year. Now we’re also seeing Journeys and Library labels in testing, with even more names in the running.

How we made JSON.stringify more than twice as fast

JSON.stringify is a core JavaScript function for serializing data.

A faster JSON.stringify translates to quicker page interactions and more responsive applications. That’s why we’re excited to share that a recent engineering effort has made JSON.stringify in V8 more than twice as fast. This post breaks down the technical optimizations that made this impr

C++26 Reflections adventures and compile-time UML

The first thing I do every time I need to learn a new codebase is to start drawing the UML diagram of its classes, and usually give up soon after I started. The process of doing it manually is certainly useful, but now with reflections I figure it would be fun to try generate it instead. With C++26 reflections[1] the general consensus is that the magnitude of language change is comparable to what happened with C++11. After my little experiment with it, I would cautiously agree.
