I love the whole idea of the port system. It was one of the reasons why I decided to go for Gentoo. So, I emerge my world with the official Portage package manager on Gentoo :)

$ sudo eix-sync
$ sudo emerge -auDU --with-bdeps=y @world

On KaOS (my laptop), I use the official package manager, too, though it is a rather boring installer: Pacman ;P (on KaOS, the packages are quite stable, as opposed to Arch Linux, so it usually just... works. KaOS is so very boring haha - that's why I love it)

$ sudo pacman -Syu

My web servers are still rolling Debian. They install with Aptitude. However, I want to switch them over to NixOS, which uses Nix, a "Purely Functional Package Manager".

$ sudo aptitude update
$ sudo aptitude upgrade

$ sudo nix-env -u

For Windows, I prefer Chocolatey . I automated it to run a world update on every system start, so I can always have the latest stuff. It helped me install a few things which were difficult before (ghostscript >.>).

PS > sudo cup all -y

Lately, I am tinkering with a Hackintosh (gotta develop an app which has to run on iOS, so..). I will most likely install Homebrew on that (because macOS is by no means a priority platform for me), though I might as well roll MacPorts, to stay true to my preferences.

$ sudo brew update
$ sudo brew install `brew outdated`

$ sudo port upgrade outdated

Other than OS package managers, I regularly use npm for Node.JS, bower for browser and app JS and cargo for Rust.

$ npm i .

$ bower install .

$ cargo build .

On Ubuntu apt-get.

Besides that I use:

• npm -> NodeJS
• cargo -> Rust
• stack -> Haskell
• gradle -> Java

I use apt-get on my webs server and npm on my server as as well as on my Macbook. I used to use homebew and MacPorts in the past, but I find app stores in general kind of make a mess of OS X after a while so I try to avoid it as long as possible. I had to install npm recently though after waiting months hoping I wouldn't need to :D
