What it does
Portia is a native macOS utility that hunts down processes blocking your ports. Zero idle CPU, no shell plugins, just one-click precision.
Stop spinning webs of lsof . Portia stalks, traps and strikes the process blocking your port — in one click. A real Portia spider stalks for hours, plans the perfect angle, then strikes in a single leap. Your terminal deserves the same discipline. Portia installs as a macOS Launch Agent and waits — listening to system signals, not polling. Zero CPU until something moves. The instant a process crashes with a port collision, Portia identifies the offender, the PID, and the exact socket holding the port hostage. A native notification slides in. Click Strike and the blocking process is gone. No terminal, no lsof , no fumbling. Lightweight, native, and unintrusive. Portia respects your machine…from getportia.app

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…

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!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
