   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.

    Local development with .local domains and HTTPSfree tier, from $8/mo▲84

    Hi HN! I'm Jarek, and I've built this tool that allows publishing .local domains on the local network using mDNS. It also has a reverse proxy that handles HTTPS termination and port forwarding.
