Google's New AI Tool Solves a Problem for Every Lazy Developer

by: Sourav Rudra Tue, 02 Dec 2025 11:17:07 GMT Back on November 13, Google launched Code Wiki in public preview. The platform automatically generates and maintains documentation for code repositories using Gemini.

There are, however, some caveats. Even though it is based on open source Chromium project, Chrome has been under fire again and again over the years because of privacy co

Chris’ Corner: Web Components

by: Chris Coyier Mon, 01 Dec 2025 18:25:26 +0000 I’d never heard of a CEM before. That’s a “Custom Elements Manifest” or a custom-elements.json file in your project. It’s basically generated documentation about all the web components your project has. Dave calls them the killer feature of web components. I love the idea of essentially getting “free” DX just be generating this file. I particularly like the language server idea so that code editors can offer all the fancy autocomplete and

Prevent a page from scrolling while a dialog is open

by: Geoff Graham Mon, 01 Dec 2025 17:25:28 +0000 Bramus: YES! Way back in 2019, I worked on “Prevent Page Scrolling When a Modal is Open” with Brad Wu about this exact thing. Apparently this was mere months before we got our hands on the true HTML <dialog> element. In any case, you can see the trouble with active scrolling when a “dialog” is open: CodePen Embed Fallback The problem is that the dialog itself is not a scroll container. If it was, we could slap overscroll-

ObsidianOS Review: A New, Innovative Linux Distro Built Around A/B Partitioning

by: Neville Ondara Mon, 01 Dec 2025 07:42:54 GMT Most new Linux distributions tend to follow a familiar formula: take a well-known base, add a desktop environment, sprinkle in some theming, and call it a day. Sometimes it works; sometimes the distro disappears in six months. What you don’t often see, however, is a distro trying to rethink how updates, rollbacks, and system integrity fundamentally work. ObsidianOS is one of those unusual projects that immediately caught my attention for exa
