I'm still a bit confused about the nuances between the myriad of ways to handle
variables in Emacs...
- `setq`
- `setq-default`
- `setq-local`
- `defvar`
- `defcustom`
- `defconst`
- `customize-set-variable`
- `make-local-variable`
- `make-variable-buffer-local`
- `kill-local-variable`
...but after running some experiments, this triggers the Emacs debugger when an
error is encountered (e.g. either *in* `init.el` or another package that is
evaluated during `init.el`'s evaluation).

In my opinion the following versions of compound words should be searched
similarly...
- `testingThisOut` (camel case)
- `TestingThisOut` (class case)
- `testing_this_out` (snake case)
- `testing-this-out` (kebab case)
...but Emacs's default searching treats the snake and kebab cases differently,
which makes it difficult to search for buffer-local occurrences of symbols in
Python, Elisp (among other languages).
This has been bothering me for some time. I must've attempted to fix this awhile
ago by using `setq` (when I should've used `customize-set-variable`, which makes
me wonder: how much of my configuration is flaky because I'm using `setq` where
I should be using `customize-set-variable`?

In the spirit of learning by doing, I decided to implement a simple blockchain
server. More work remains, but I'm tired after working on this for ~2-3h. I'd
like to reimplement this from memory using a statically typed language like
Haskell. I'd also like to implement node
discovery (https://en.bitcoin.it/wiki/Satoshi_Client_Node_Discovery) because
that is still something I don't quite understand. But I'm signing-off for
now...

and then encoded as hexadecimal creating the ciphertext.

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
