Guru's Tech Bytes — Episode 13

Good morning. This is Guru's Tech Bytes, Ep. 013, for Thursday, April 16th, 2026. First up, the internet just hit a quiet milestone. IPv6 traffic has officially crossed the fifty percent mark worldwide, according to Google's own tracking data. After decades of "we're running out of addresses" warnings, the newer protocol has finally overtaken its predecessor. It's not glamorous, but it's the kind of infrastructure shift that keeps everything else running. Second, a fascinating project called Darkbloom is turning idle Macs into private inference nodes. The idea is simple but clever: rather than shipping your data off to some cloud provider, Darkbloom lets you run AI models locally across spare Apple silicon machines. With over two hundred and eighty upvotes on Hacker News, it clearly struck a nerve with developers who want powerful inference without handing their data to someone else. And finally, OpenAI's Codex managed to hack a Samsung TV. A developer documented how they pointed the AI coding agent at a Samsung smart TV and it successfully found and exploited vulnerabilities in the device. It's equal parts impressive and slightly terrifying, and a reminder that AI agents are getting rather good at poking holes in things we assumed were secure. That's your daily byte. Have a great day. Until next time.
