75595b0126 Parse and serialize rules.json
TL;DR:
- Write FromJSON instances to decode rules.json file
- Prefer Text to String and use the OverloadedStrings language extension
- Read /etc/hosts and append the serialized rules.json to the end

Notes:
- I can remove some of the FromJSON instances and use GHC Generics to define
  them for me.

561cb619a1 Add <unstable> to NIX_PATH
1. I should be using NixOS/nixpkgs-channels instead of NixOS/nixpkgs
2. Instead of refactoring everything, I'm supporting <unstable> and pointing it
   to NixOS/nixpkgs-channels

I needed <unstable> to get a more recent version of the Data.Time Haskell
package.

f2ba5aca31 Ensure Emacs prettier hook activates
Problem:
prettier-js waits for rjsx-mode. rjsx-mode only runs on .js files. As such,
the hook that installs prettier-js-mode for *all* of my frontend hooks, which
includes more than just js files, does not install until a javascript file is
opened.

Solution:
Do not conditionally load prettier-js.

Bonus:
Remove the .js mode from rjsx.

0281eb58aa Add node_modules to .gitignore of boilerplate/typescript
briefcase's top-level .gitignore ignores node_modules, so I never noticed that
it was missing from my boilerplate .gitignore. I don't *really* need to add it
to that .gitignore, but if I want to cleanly eject directories from this
monorepo, it makes sense to keep the .gitignore files local to each project.

514136c99a Run Prettier across projects
Problem:
Prettier was not running when I saved Emacs buffers.

Why?
- prettier-js-mode needs needs node; lorri exposes node to direnv; direnv
  exposes node to Emacs; lorri was not working as expected.

Solution:
Now that I'm using nix-buffer, I can properly expose node (and other
dependencies) to my Emacs buffers. Now Prettier is working.

Commentary:
Since prettier hadn't worked for so long, I stopped thinking about it. As such,
I did not include it as a dependency in boilerplate/typescript. I added it
now. I retroactively ran prettier across a few of my frontend projects to unify
the code styling.

I may need to run...
```shell
$ cd ~/briefcase
$ nix-shell
$ npx prettier --list-different "**/*.{js,ts,jsx,tsx,html,css,json}"
```
...to see which files I should have formatted.

6b224a9e31 Drop support for lorri
Lorri does not cleanly integrate with my corporate device, which cannot run
NixOS. To expose dependencies to Emacs buffers, I will use nix-buffer.el, which
reads its values from dir-locals.nix. To easily expose dependencies from my
existing shell.nix files into dir-locals.nix, I wrote a Nix utility function.

062af32e4e Solve InterviewCake's find duplicate beast mode
Write a function to find a duplicate item in a list of numbers. The values are
in the range [1, n]; the length of the list is n + 1. The solution should run in
linear time and consume constant space.

The solution is to construct a graph from the list. Each graph will have a cycle
where the last element in the cycle is a duplicate value.

See the solution for specific techniques on how to compute the length the cycle
without infinitely looping.

3ff6ae3697 Use Parcel's --public-url option when building
By default Parcel prefixes output paths with /. So when Chrome loads
wpcarro.dev/goals it attempts to get the CSS and JS and other assets from
wpcarro.dev/ instead of wpcarro.dev/goals/. Using the --public-url ./ option
makes Parcel output relative paths, which should work better for my needs.

06d2467c56 Use boilerplate/typescript for goals
After deploying the version of this application that built everything in the
browser, which originally was the impetus for the entire project, I learned that
the babel in-browser transformer won't work. I'm not sure why, but I need to
move on from this project and do other work.

I ported the code to my boilerplate/typescript, which works. Wahoo!

265b691c9b Add @types/node to typescript boilerplate
Parcel uses process.env to expose environment variables. Since process.env is a
Node concept and this boilerplate is for TypeScript projects, we need

9fdf4d00fa Support boilerplate for TypeScript projects
I would like to support boilerplate code for ReasonML, TypeScript,
ClojureScript, and Elm projects before I specialize in any of these
frameworks. All of my projects should use TailwindCSS.

All of this boilerplate should offer:
- Same command to start developing
- Same API to build and deploy
- TailwindCSS support
- Basic boilerplate for components, state, and routes

This TypeScript boilerplate is not complete, but I would like to commit the
progress in case I do not return to this for awhile.

ae9e83f5d7 Solve InterviewCake.com's mesh-message problem
Write a function that returns the shortest path between nodes A and B in an
unweighted graph.

I know two algorithms for finding the shortest path in a *weighted* graph:
- Use a heap as a priority queue instead of the regular queue that you would use
  when doing a BFT. This is called Dijkstra's algorithm. You can also use
  Dijkstra's algorithm in an unweight graph by imaginging that all of the
  weights on the edges are the same value (e.g. 1).
- Map the weighted graph into an unweighted graph by inserting N nodes between
  each node, X and Y, where N is equal to the weight of the edge between X and
  Y. After you map the weighted graph into an unweighted graph, perform a BFT
  from A to B. A BFT will always find the shortest path between nodes A and B in
  an unweighted graph.

I had forgotten that a BFT in an unweighted graph will always return the
shortest path between two nodes. I learned two things from InterviewCake.com's
solution:
1. I remembered that a BFT in an unweighted graph will return the shortest
   path (if one exists).
2. I learned to use a dictionary to store the edge information and then
   back-tracking to reconstruct the shortest path.

76210a217c Attempt to serve sandbox.wpcarro.dev/covid-19
Right now my website is serving at sandbox.wpcarro.dev, but I would rather
people view it at sandbox.wpcarro.dev/covid-19.

I previously tried to accomplish this with the following Nginx configuration:

```nix
locations."/covid-19" = {
  root = briefcase.covid-uk;
}
```

I am now trying `alias = ...` instead of `root = ...`. I got the idea from this
SO question, https://stackoverflow.com/questions/10631933/nginx-static-file-serving-confusion-with-root-alias.

1d45f14615 Update COVID-19 webpage
- Prefer hosting on sandbox.wpcarro.dev; I would prefer to host it at
  sandbox.wpcarro.dev/covid-19, but I haven't figure out how to use Nginx to do
  serve locations like /covid-19 yet.
- Splice the src directory: When I develop locally and index.html exists within
  ./src, I cannot access ./node_modules because ./node_modules is in a parent
  directory. I could fix this if I used a bundler like Parcel or Webpack, but I
  do not want to set that up at this time.
- Introduce Tailwind for CSS. This complicates my build a bit as well. For now,
  I'm including output.css even though ideally I should not version-control this
  file. I haven't figured out how to `yarn install` and run commands like `npx
  tailwindcss build styles.css -o output.css` in a Nix derivation yet. Hopefully
  I will learn and refactor this.
- Add some content about why I made this chart
- Add some content about some of my covid-19 predictions

c627fa9cbd Prefer live timeseries.json
When I was first developing this, and I attempt to access
https://pomber.github.io/covid19/timeseries.json, the browser prevents me from
reading the data because it violates the same origin policy.

I'm learning more about CORS, and I'm going to try consuming this from...
https://wpcarro.dev -> https://pomber.github.io
...instead of...
http://localhost:8000 -> https://pomber.github.io
...because the http -> https protocol violates CORS.

I will not know unless I try, so... bombs away.

It has been awhile since I have written a tutorial. I have spent 2-3 hours

- "Let's Learn Nix" reproducibility: Where I list all of the tutorials'

- Haskell type signature convention for Nix
- Ad hoc vs. declarative configuration for Nix
- Troubleshooting Nix: <nixpkgs> search, nix repl, searching the Nix codebase

ebf0ef7e34 Delete .xsessionrc
Nix home-manager generates an .xsession file for me. I believe there are a few
files for managing X-sessions:
- .xinitrc
- .xsession
- .xsessionrc: Only exists on Debian systems, which is why home-manager
  generates an .xsession file instead. gLinux is a Debian system.

Whenever I close Emacs, another Emacs initializes. I believe this is because
after I allowed home-manager to manage my X-sessions, I unintentionally
supported two X-session configuration files: .xsession and .xsessionrc; both of
these files initialize Emacs.

I'm deleting my .xsessionrc, and I'm hoping that will remove the issue.

Enable autorandr with Nix home-manager. I discovered autorandr when looking

it doesn't.

With autorandr, I run...

```shell

```

...to load my randr settings for just my laptop without the external monitor,
and I run...

```shell

```

...to load my randr settings for my external monitor.
