Chrome 155 adds support for JPEG XL (.jxl) → goo.gle/4yYpSjW Expect 30-50% smaller file sizes than traditional JPEGs, native HDR, progressive rendering, and lossless JPEG transcoding. Under the hood, Chrome uses jxl-rs, a pure Rust decoder built for maximum memory safety and performance.

Git 2.56 is here. ⚡ The new git add --resolved stages only paths that are still marked as conflicted, and refuses to stage them if conflict markers remain. One merge-base case dropped from 0.68s to 0.01s. The highlights 👇 github.blog/open-source/git/…

Sick of full-screen "ad torture" just to check a cricket score? 🏏 I built COVERDRIVE - an ultra-clean alternative with exactly ONE banner. Don't even want that? You can toggle it off completely for free. Check live scores here: coverdrive.live/

CoverDrive — live cricket scores

Fast, clean live cricket scores, ball-by-ball commentary, scorecards and stats. No clutter.

Ever watched your coding agent confidently write massive amounts of JavaScript for a simple swipe gesture, only for the animation to stutter? 😅 Watch our side-by-side test: with Modern Web Guidance enabled, the coding agent pulls expert-vetted swipe-to-remove guide into its context window, handling features like scroll snap and intersection observer with ease → goo.gle/mwg
