People can also use the Nix package manager on any distro, and run their apps using nix-shell, so that they don’t need to install as root.

Are people still buying Windows after the invention of KMSPico ?

There are big differences between Snaps and Flatpaks.

• both the flatpak server and the client are open source
• flatpak does not publish 3rd party apps, promoting them as verified (https://news.itsfoss.com/valve-steam-snap-ubuntu/)

I don’t agree that it made any sense to do that. If they wanted to containerize apps, there has been an open source solution to that for years; Flatpak.

ain’t nobody got time for that

As an app maintainer, that wants to support Ubuntu, why would I prefer to deploy a snap server, instead of publishing deb files, or creating a Flatpak?

I am trying to understand.

Docker, which uses OCI containers that are supported by Docker, Podman, Containerd, systemd-nspawn, etc, is lock-in.

But Nix Shells, which require Nix, are not lock-in.

Also, how are you going to run Nix shells in VLANs? They run on the host’s network namespace.

Docker is not only about dependency management. It also offers service “composing”, via docker compose, and network isolation for each service.

Although I personally love Nix, and I run NixOS on some of my servers, I do not believe it can replace Docker/Podman. Unless you go the NixOS Containers route.
