108da34dd9 Delete unused KBDs
Now that everything is in my monorepo, it's easy for me to use <SPC>jd to search
for these files.

0c71fc9d1d Drop support for dir-locals.nix, <nixpkgs>, etc.
In the spirit of Marie Kondo, I'm tidying up!

TL;DR:
- Prefer .envrc `use_nix` and delete all dir-locals.nix files
- Remove ~all references to <nixpkgs>, <unstable>, <depot> and prefer
  referencing each with briefcase.third_party.{pkgs,unstable,depot}
- Delete nixBufferFromShell function since I was only using that in
  dir-locals.nix files

51ec9e0d88 Move /home/wpcarro/nixpkgs-channels to /var/lib
My builds are still failing. This time with...
```
error: getting status of /home/wpcarro/nixpkgs-channels: Permission denied
```
...what confused me was the following:

```shell
$ sudo -u buildkite-agent-socrates stat /home/wpcarro/nixpkgs-channels
permission denied
```

But `ls -al /home/wpcarro | grep nixpkgs-channels` showed `r-w` for all users...

Thankfully @riking on ##tvl told me that I should check the permissions for
/home/wpcarro and /home...

After running `ls -al /home`, I saw `---` for all user... I then reproduced the
error by running:

```shell
$ sudo -u buildkite-agent-socrates stat /home
permission denied
```

Great!

So then I moved nixpkgs-channels to /var/lib/buildkite-agent-socrates. @edef
recommended that I read more about DynamicUser= setting for systemd, which looks
relevant after I took a cursory glance.

I'll also want a more declarative way to manager this, but I'm making small
improvements every day.

79904056af Move buildkite's SSH key out of /home/wpcarro into /etc/ssh
After enabling buildkite-agent using NixOS, it runs as its own user,
buildkite-agent-socrates, which does not have its own home directory. I moved
the SSH key that I made when running buildkite-agent as wpcarro into /etc/ssh
and `chown`'d it for buildkite-agent-socrates.

42efb3b08a Support build-briefcase.sh
For now, I'm supporting two CI pipelines:
- build-socrates
- build-briefcase

Conceptually, build-briefcase should cover what build-socrates does now, but
eventually I would like build-socrates to call `switch-to-configuration` so that
all of my websites, etc. stay fresh.

59f7481411 Revise previous opinions about absolute paths GT <bracket-notation>
Unforeseen problem: `buildkite-agent` runs its builds in a separate directory,
so if I want the `nix-build` command to build the newly checked out code, I need
to set <briefcase> to the CWD.

7833632a79 Attempt nix-build instead of nixos-rebuild switch
I've encountered a few problems with attempting to support nixos-rebuild:
- the activation step requires `sudo` privileges
- the `buildkite-agent` runs on the same machine, socrates, that is rebuilding
  itself. This means that when the activation step runs, it will attempt to
  restart `buildkite-agent` when the agent is still working

I'm slowly removing places in my nix code that rely on '<bracket>' notation, so
that I no longer depend on NIX_PATH being set. I still have more work to do.

{covid-uk,sandbox}/default.nix are breaking when I attempt to run my
build-socrates.sh script locally, so I'm temporarily disabling them until I can
get CI working as I expect.

51cdb87223 Prefer nixos-rebuild to the rebuild script
The rebuild script calls sudo, which I won't need as I test running
buildkite-agent prefixed with `sudo` or as the root user.

2bf3c6c926 Log all polkit actions to find action.id for nixos-rebuild
I would like to setup a polkit rule to allow `buildkite-agent` (i.e. a
forthcoming user) to call `nixos-rebuild`. I need to know the `action.id` before
I can write a reliable rule.

6c0777aada Create an assessment directory
I've been doing a few take-home assessment recently, all of which I've attempted
to solve using Haskell. I'm having a good time, and I'm noticing strong and weak
points with my Haskell programming. I always attempt to apply any feedback a
reviewer gives me, and I'm storing my first drafts, second attempts, and
feedback here for now.

This recently attempt was for a role at Jane Street.

375c4a4c85 Restore shell.nix
I believe `use_nix` looks for shell.nix and then default.nix files, so I was
wrong earlier when I said that I could get rid of shell.nix files altogether.

I need to learn more about `use_nix` and getting environments from default.nix
files.

56b503c573 Prefer direnv's use_nix to shell.nix
I find it bothersome to share the list of Haskell dependencies between my
default.nix and shell.nix files. A few days ago, I created a THIRD file,
shared.nix, that defined the shared code b/w default.nix and shell.nix. This
DRY'd things up, but it also added a new file, which I didn't like.

Today I learned that direnv integrates with Nix using a function called
`use_nix`. Voila! I typically already have .envrc files per-project, so this
doesn't add any unnecessary files, and it allows me to delete my shell.nix
files.

I would use `lorri`, except that I encountered issues using Lorri on my work
computer, which I'm not interested in attempting to resolve now.

979cbda33c Remove logging prefix from Nginx logs
Problem: The JSON that Nginx outputs cannot be successfully parsed by
journaldriver because Nginx prefixes it with "socrates nginx:". Adding
`nohostname` to `access_log` should solve this problem.

I borrow this from @tazjin's most recent definition of `commonHttpConfig`.

81aa32fe71 Support POST /create-payment-intent
Interact with Stripe's payment_intents API endpoint.

I'm not committing the index.html that contains client-side code that interacts
with the /create-payment-intent endpoint, but it contains sensitive information,
so I'm omitting it for now.

TL;DR:
- Define POST /create-payment-intent endpoint
- Include envStripeAPIKey in Context record
- Define a top-level Stripe module for making API calls
- Define types and instances that align with Stripes request and response types
- Depend on the Req library: a higher-level library than http-client

de723c142b Prefer project.el to projectile
Today @tazjin told me about Emacs's built-in project.el library, which he
recommended that I extend to support monorepo-specific tooling. It worked like a
charm!

Now when I press "<leader>f", it will resolve to either the nearest file named
default.nix or directory name .git.

4ea55dd013 Support buildHaskell
Use Nix and Briefcase to easily create Haskell executables.

I'd eventually like to support something like: briefcase.buildHaskell.project
that let me define a few top-level values (e.g. ghcExtensions) and would give me
a ghci environment with the proper `.ghci` settings so that my development
environment mirrored my build environment... baby steps, though.

bba3f16c43 Prefer snake-shift instead of a row-by-row shift
Per the assignment's instructions, the `Shift n` operation should treat
the *entire keyboard* like a cycle and shift that. I was erroneously
treating *each row* like a cycle and shifting those one-by-one.

This change fixes that. In addition, it also:
- Updates README.md with expected inputs and outputs
- Updates test suite
- Adds `split` dependency to {default,shell}.nix

17e1764ef8 Generate coords function from existing qwerty keyboard
Per my take-home assignment's reviewer's comments, with which for the record I
agree, I should generate the character->coordinate table from my existing qwerty
keyboard definition.

The best part is: by doing this I found a bug: Notice how the original '0'
character was mapped to the Coordinate (0,0)... thus every subsequent digit
key (i.e. the first row) is off-by-one.

4ff1ea291c Drop support for ServantT transformer type for server
After burning a few hours wrestling with the type system, I decided to revert to
the simpler `Server API` type instead of the `ServantT` transformer type.

The problem is that I couldn't write a MonadError instance for `RIO Context`,
which is my `AppM` (i.e. application monad). Using `throwIO` in the server
handlers results in 500 errors, which is not what I wanted. I'm still pretty
fuzzy about what's happening; I now know that exception handling in Haskell is
pretty gnaryly. I may revisit this at a later time when my knowledge is more
extensive. For now: time to fry bigger fish.

An easier abstract is for me to pass `T.Context` into `server` as an argument,
which after all is what a Reader does.

TL;DR:
- Read server, client ports from .envrc
- Define a top-level Failure type (empty for now)
- Define a top-level Success type
- Define App as RIO Context (Either Failure Success)

f61ed25755 Prefer ServantT for server to consume App context
Long story -> short: I'd like to access my App monad from within my Servant
handlers.

While this code type-checks, I'm not sure it's working as intended. Needing to
change throwError to throwIO fails the "smell test". I expect to refactor this
code, but I'm calling it a night for now.
