Pretty cool as a learning exercise. As a follow up scenario maybe try moving this infrastructure to another cloud provider because AWS deleted your account without warning or try a multi-cloud deployment.

Regarding Lets Encrypt your server doesn’t need to be accessible from the internet if you use the DNS-01 challenge. Caddy with the caddy-dns plugin for your provider can do that automatically for you.

Either use the sftp command, it also supports the -J option, or use SSH tunneling. For example here I bind the homelab port 4533 to my local port 8080.

$ ssh -L 8080:vpn-homelab-ip:4533 user@vps-ip
(user@vps) $

I can now open a new shell and run:

$ curl http://localhost:8080/
<a href="/app/">Found</a>.

You could also do it this way:

$ ssh -L 8080:localhost:4533 user@vpn-homelab-ip -J user@vps-ip
(user@homelab) $

According to the Pangolin docs it supports raw TCP and UDP connections.

For SSH you can also try to use the VPS as a jump host like this:

$ ssh user@vpn-homelab-ip -J user@vps-ip

The source code is freely available and GNOME isn’t beholden to Canonicals decisions. If the Ubuntu devs want to keep X11 around nobody can stop them from maintaining it themselves, or pay somebody from the GNOME team to do it for them.

Imagine how successful their store could have been if they had put all that money into improving the launcher and not antagonizing large parts of their customer base instead.

I really like it as well. I did three major version upgrades so far and they have been flawless. I also really like Flatpak, finally a way of easily installing something on Linux without breaking half of the system because the application you wanted to install uses libfoo 2.0 and not libfoo 1.9.9-patch-1337. With my atomic desktop applications that worked yesterday also work today. Things don’t randomly break all the time.

The future of Fedora Atomic also looks exciting; Timothée Ravier is working on sysexts which are a way of installing applications without ostree layering. I could remove most of my ostree layered packages with that.

We use OpenProject at my job and its pretty good. You can use the Nextcloud as a document repository and integrate it with OpenProject.

I consider the fact that karma farming isn’t a thing on Lemmy a massive improvement over Reddit.
