dbb24e0377 feat(ops/nixos/nugget): Set up nginx serving homepage & blog
This nginx does not currently log access correctly because for some
impenetrable reason (as is tradition), neither /dev/stdout nor
/dev/fd/1 exist for nginx at runtime. This is probably systemd's
doing, but I'll debug it later.

Eliminate Flag's destroy method.

The Abseil Flags are never destroyed. The only place where Destroy method was invoked was in some obscure place during flag registration, where we faces with duplicate retired flag registration. Regired Flag destruction is empty anyway. so we can just delete the duplicate object. The FLagImpl::Destroy is never invoked.

85cdd46f00 Attempt to support TypeScript for coding challenges
I was a bit weaker than I expected to be in my most recent interview using
TypeScript. To improve, I think I'd like to attempt solving some of the
InterviewCake.com questions using TypeScript.

If you've read the previous commits, the inspiration for `run` arose because I
need to call `npx ts-code <file>`, which is easy enough to remember, but I'd
still rather just call `run <file>`.

3afb56a5e5 Begin supporting run
I'd like to be able to just call `run file.py` and have a program DWIM. I'm
working on run as a step in this direction. Define a simple configuration that
maps file extensions to template strings where "$file" is replaced with the
argv[1].

It basically works but there are outstanding TODOs. See the README and source
code for more information.

d81f31107d Support cycling through display configurations
Today when I opened my laptop, I wasn't sure if it was powered off or on because
the display was blank. Thankfully the volume was muted and the LED indicator was
on, which informed me that the laptop was powered on. This saved me from
unnecessarily rebooting.

What happened was that last night I was working from home and using my external
monitor. Usually I enable my external display and disable my laptop display. But
when I left for work this morning, I unplugged the HDMI cable from my laptop
without disabling the external display or enabling the laptop display.

I noticed a XF86 button on my laptop entitled XF86Display. I figured that this
could be a nice place to bind a key to toggle my laptop display on or off. At
the last minute, I had the idea to just cycle through all possible display
configurations that I use; there are only three anyways. When dealing with more
than two states, I realized I should use a cycle to model the configuration
states. Now I'm thinking that I should be using cycles to model toggles as well
- instead of just using a top-level variable that I `setq` over. I haven't
refactored existing toggles to be cycles, but I am excited about this new
keybinding.

This commit additionally:
- Moves keybindings out of display.el and into keybindings.el
- Conditionally sets KBDs if using work laptop

61be808a92 Preferring to start wpcarros-emacs with dbus-launch
When I ran `pass show some/password`, gpg, which uses pinentry would start its
ncurses password prompt. For many this wouldn't be a problem but my current
vterm version cannot send the <return> key to ncurses, so once that prompt
appears, I cannot get rid of it without C-c and killing the shell. For a day or
more I just opened suffered through this.

Today I dug more into the issue and when I ran `pinentry --version` it warned
that it couldn't connect to DBUS. After searching for more information on this,
people with similar issues recommended starting their window managers with
`dbus-launch`. I previously started Emacs with `dbus-launch`, but only because
some i3 documentation told me to do so and I just copied them. Then I switched
to EXWM and copied that pattern over. A friend of mine uses EXWM and starts his
without calling `dbus-launch` but `exec emacs`. I mirrored this thinking that I
no longer needed `dbus-launch`. What I didn't know, however, was that this
friend was using a Nix-built Emacs (like me) except that his wrapped a native
Emacs installation while mine doesn't. His natively wrapped Emacs installation
has the proper variables set to interact with dbus and other important Linuxy
things that I don't fully understand. Since I'm using a Nix-built Emacs, some of
my variables are unset or set to different values than programs expect. This is
why when I try and start `gnome-terminal` or `terminator`, they refuse to start
and warn about many unset or incorrectly variables and not being able to bind to
sockets, etc.

This change reverts back to using `dbus-launch` until I have a better
understanding of Linux, Nix, etc.

Re-enable type mismatch check, which works in all the cases including shared libraries.

We will use RTTI in case when our hand written approximation of it reports a type mismatch. This way we can ensure that if a flag is defined in one shared object and referenced in another we do not report spurious errors.

20e2624203 Adding a few cities that I visited in 2019
I spent two weeks on the Spanish islands of Ibiza and Formentera over the
summer.

I went to Hamburg twice to visit Mimi's family - once in the summer; once for
Christmas.

In the Fall, I went to Bordeaux with Mimi where we stayed at a charming Airbnb.

I spent New Years Eve in Amsterdam with Matty, Ryan, and Conor.

I may be missing a few other places that I visited in 2019; it was an active
year.

d35eb5c8f9 Debug os.Signal handling
Problem:

When SIGINT signals we're sent to the token server, it would shut down without
completing the shutdown procedure. The shutdown procedure would persist the
application state (i.e. access and refresh tokens).

This is problematic for the following sequence of events:
t0. Access and refresh tokens retrieved from kv.json and used as app state.
t1. Tokens are refreshed but not persisted. (I'm still unsure how this
    happens). Remember that this means the previous access and refresh tokens
    from t0 are now invalid.
t2. User sends a SIGINT.
t3. Token server shuts down.
t4. Token server is restarted, kv.json is used as the app state even though its
    tokens are now invalid.
t5. Tokens are attempted to refresh, Monzo API rejects the tokens because
    they're invalid.

Now we need to provide the token server with valid access and refresh tokens
otherwise we will repeat the loop described above. This means going through the
client authorization flow again or copying and pasting the tokens logged from
the token server into kv.json. Either scenario is more manual than I'd prefer.

Solution:

Use a buffered channel to receive the os.Signal. I got this idea after reading
these docs: https://golang.org/pkg/os/signal/#Notify and I debugged this issue
shortly thereafter.

I also rearranged the order of operations in main/0 to ensure that
handleInterrupts/0, which registers the event listeners, occurs before
scheduleTokenRefresh/2 is called. This allows the token server to gracefully
shutdown even if it's in the middle of the scheduleTokenRefresh/2 call.

44dca4a188 Move authorization logic into separate package

in a file called kv.json.

- Support better error handling
