What it does
PortKill9 is a native macOS app that kills any process occupying a port — one click, one second, done. No more typing `lsof -i :3000`, finding PID, running `kill -9`. Just enter your port number and hit Kill. Built for developers who restart local servers daily and constantly fight "port already in use" errors. Especially handy for vibe coding workflows where you're spinning up and tearing down dev environments all day long. Native macOS experience. Zero dependencies. Just works.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
