Arch Linux: A Developer-Friendly Operating System

Arch community repo is the best, any obscure software you are looking for is there one command away of installing it.

Arch wiki is an endless source of information, not even Ubuntu has such support.

Also its highly recommended you follow the wiki install guide (if you have a couple of days) since it will teach you a lot about the different parts that make up your *nix operating system.

Once you have done that and you are feeling lazy i've found Antergos easy to install while keeping the same flexibility as vanilla Arch.

Also, finally, if you are a dev i'd recommend zsh + oh my zsh to have a sleek terminal.

I ran it for a few years but they do have breaking changes sometimes. It's a great system if you want the latest versions but that daily update can sometimes make you spend hours troubleshooting, and that's not great for a work environment where everything needs to just work.
