Guru's Tech Bytes — April 9, 2026

Good morning. This is Guru's Tech Bytes, Ep. 006, for Thursday, April the 9th, 2026. First up, a developer has ported Mac OS X to the Nintendo Wii, and yes, you read that right. Bryan Keller documented the entire process of getting Apple's operating system running on Nintendo's decade-old console, complete with Aqua interface and all. It's the kind of beautifully pointless engineering that reminds you why people got into computing in the first place. The Hacker News crowd loved it, racking up over sixteen hundred upvotes. Second, LittleSnitch, the beloved Mac firewall app that lets you see exactly which apps are phoning home, has officially launched for Linux. Objective Development's network monitor gives you fine-grained control over outbound connections, which is brilliant news for anyone who wants to know what their system is up to behind their back. With over eight hundred upvotes, the Linux community is clearly chuffed. And finally, Astral, the team behind the Python tools uv and Ruff, has published their approach to open source security. They're detailing how they handle supply chain risks and code signing for tools that millions of developers depend on daily. Rather important when your package manager is installing half the internet. That's your daily byte. Have a great day. Until next time.
