Modernizing Web UI Controls: The Open UI Community Group's Mission

Web interactivity stems from HTML's form and UI controls. However, since HTML5, complex web projects require more powerful UI control capabilities, leading developers to rely on JavaScript frameworks. This results in poor accessibility, slow page speeds, and other issues. The Open UI Community Group aims to improve HTML, CSS, JavaScript, and Web APIs to empower developers to build modern custom user interfaces. Their goal is to make web UIs more flexible, efficient, and accessible.

YouTube Experiment: DRM-Only Videos on TV?

Reports indicate YouTube is experimenting with a limited rollout where normal videos only offer DRM-protected formats on the TV (TVHTML5) Innertube client. This affects not only yt-dlp, but also official YouTube TV clients (PS3, web browser, Apple TV), which also only provide DRM formats. Tests show accounts involved can only access DRM-protected versions. This suggests a potential shift in YouTube's copyright protection strategy, potentially impacting how users watch and download videos.
