🚨 Someone built a full virtual computer that runs inside your browser. No downloads. No installs. No VMs. Just a Docker command. It's called Neko. It runs a complete desktop environment inside a Docker container and streams it to your browser using WebRTC. Not a screen share. Not a remote desktop. A real computer running in a container that you control from any browser tab. No VNC lag. No RDP setup. No TeamViewer watermarks. Just smooth, real-time video and audio. Here's what this thing can do: → Run Firefox, Chrome, Brave, Edge, Tor Browser, or Opera in an isolated container → Run full desktop environments like XFCE or KDE → Multiple users can watch and control the same session simultaneously → Built-in audio streaming. Watch videos together with perfect sync → Persistent sessions. Close the tab, come back later, everything is still there → GPU acceleration for smooth rendering → Embed it in your own web app via API Here's why people are losing their minds over this: Watch parties. Open a movie, invite friends, everyone sees the same screen in real-time with synced audio. Open source alternative to Hyperbeam. Throwaway browsing. Need to visit a sketchy site? Do it in a disposable container. Nothing touches your real machine. Pair it with Tor Browser and a VPN for full anonymity. Team collaboration. Debug code together. Brainstorm on a shared whiteboard. Give a live demo where your audience can actually click around. Secure jump host. Access internal company apps from anywhere without a VPN. Only video leaves the container. No cookies, no tokens, no data on the client. Here's the wildest part: The backstory. The creator built this because rabb.it shut down and he just wanted to watch anime with his friends. Discord kept crashing. His internet couldn't handle streaming. So he built an entire virtual browser platform from scratch. One Docker command to start: docker run -d -p 8080:8080 m1k1o/neko:firefox Open localhost:8080. You now have a full browser running in the cloud that anyone can join. 17.3K GitHub stars. 1.2K forks. 2,133 commits. 57 contributors. 100% Open Source. Apache 2.0 License.

JavaScript now has non-mutating array methods ✨ `toSorted()`, `toReversed()`, `toSpliced()`, and `with()` return new arrays instead of modifying the original. No more [...arr].sort() to avoid side effects. Learn more 👇 developer.mozilla.org/en-US/docs/Web…
