Ubuntu
I am using ubuntu, a linux distro based on Debian. It is open source, with a big community and support for common issues.
Oh my zsh
Ubuntu has a default shell, to run different commands, but there are others like
zsh. To add more power to the shell, I used Oh my zsh on top. It is open
source, big collaborative community, customizable and with many plugins to
enable to enrich the experience of working with a terminal.
dotfiles
Private files in a Linux os. Usually, they contain configuration used by different tools, like terminal, profile, k8s, git... It can be used to speed up installation of a new OS from scratch. Totally customizable with my needs.
