I think this is a form of symmetric encryption where the passphrase (e.g. "ICE")
is repeated (e.g. "ICEICEICEICEI...") until it matches the length of the
cleartext string; after that, the two byte-strings are XOR'd against one another
and then encoded as hexadecimal creating the ciphertext.

Preferring billandhiscomputer.com in lieu of wpcarro.dev. wpcarro is a bit of a
tough username for others to remember and for me to say out-loud (it usually
involves me spelling it and explaining to others why Carroll is missing
2x-Ls). I think it's time for a change.
During the transition, I don't want to deal with stale links to
https://wpcarro.dev, so I'm templatizing more of my website and blog so that
these values can be replaced.
Expect more forthcoming changes.

This support reverse-DNS lookups.
I encountered a problem where I accidentally deleted my instance's
`nat_ip` (external, ephemeral IP). I needed to run...
```shell
terraform apply -replace=google_compute_instance.diogenes
```
...which invalidates terraform's local cache of the state. I believe this used
to be called `terraform taint`. Things are mostly WAI, with one known issue:
quasselcore and billandhiscomputer.com complain about missing SSL certs, but I
believe this is a race-condition. Calling...
```shell
systemctl restart quassel.service
```
...resolves the issue for quassel. Unfortunately the same doesn't work for
nginx.service, but after a bit of time https://billandhiscomputer.com "just
works". Clearly I'm not sure what's going on here. At least not yet...

After receiving another computer from Google and attempting to "easily"
install my configuration, I realized that I had some holes. In reality
these could (and perhaps should) be easily tested using CI that attempts
to cleanly install my configuration on various platfoms (e.g. Debian,
NixOS), but I'm not interested in supporting something like that (at
least not at the moment).
For now, it suffices to nixify some of the lingering shell scripts with
implicit dependencies on tools like `stow`.

Supporting SSH turned-out to be a bit of a saga... Thank you @espes and @grfn
for the pointers.
Problem: When I originally setup my Google VM, I followed this tutorial,
https://nixos.wiki/wiki/Install_NixOS_on_GCE, so I ended-up installing
`nixos-20-03`: an older version of NixOS, (the newest version in `gsutils ls -l
gs://nixos-images`). Critically, I missed this important footnote:
> NOTE: Newer images (from 20.09 on) won't be available at the bucket above, and
> will instead need to be found at
> <nixpkgs/nixos/modules/virtualisation/gce-images.nix>.
It turns out that *newer* images include this script...
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/virtualisation/fetch-instance-ssh-keys.bash
...which reads the key, "sshKeys", from the Google metadata server and copies
the value into /root/.ssh/authorized_keys.
To make matters a bit misleading, the NixOS script expects the key to be
"sshKeys", but Google deprecated that in favor of "ssh-keys" (hence why both
versions appear in this commit).
TL;DR:
- upgrading to a newer NixOS image
- adding an empty access_config block so Google will assign my VM an external IP
- removing oslogin (not necessary to do, and I may add it back later)
- adding my public SSH key as metadata
