    Rot - Offline secrets management▲116

    Finally open sourced an internal tool we've been using for managing secrets. It's similar to SOPS, but more opinionated, easier to configure/use correctly, and produces nicer git diffs. It also supports one-way encryption, so you don't have to know the private key to add secrets.

    Port Zero – How I learned to stop worrying and love PORT=0▲19

    Hi HN, Recently I wasted several hours wrangling my dev environment only to find out that the browser frontend was talking to the wrong version of the backend. This got me thinking--why on earth are we still using simple numbers to describe which process to connect to? Why not use names instead? I thought of all the times a program wouldn't start because of port conflicts. The more I thought about it, the crazier it seemed. Modern operating systems already offer no-conflict ports: if you make your TCP server listen on port 0, the OS assigns you a random available port. But that only solves…
