West Country Girl

With a crooked smile and a heart-shaped face
Comes from the West Country where the birds sing bass
She's got a house-big heart where we all live
And plead and counsel and forgive
Her widow's peak, her lips I've kissed
Her gloves of bone at her wrist
That I have held in my hand
Her Spanish fly and her monkey gland

"""check_vaccine.py

Checks CVS for vaccine appointment availability and sends text messages if they show up.

Requires paid account on Twilio. You can fund $5 and it'll be plenty, a SMS is less than 1 cent.
Assuming you use a *nix system with Python 3 and want to deploy via crontab, you can do something like this:

1. `which python` Record the output. (It's nice to give crontab the full path of your python binary.)
2. `export VISUAL=vim` (For `crontab -e` to use vim; my personal preference.)
3. `crontab -e` to create a new line in your crontab. Next line is an example:

"""Playing with means.

Geometric and Arithmetric means will only ever be equal when every item on the
list is the same. So if you keep entering 2,2,2,2,2,2,etc the two averages will
be the same. As soon as a new value is in the list the two values will diverge.

You can use this to look at how much the values diverge by with the introduction of outliers.

"""spelling_bee.py: Creates puzzles for NYT's spelling bee game.

Computers are fast. This leverages a ton of linear passes through a dictionary
because it's just for fun and puzzle examples still come back in under a second.
Performance improvements left as exercise to the reader.

No dependencies beyond Python 2.7+.

"""Python GraphViz dot generator. Create simple GraphViz dot code from a graph
builder API.

The goal is to hook this up with a GUI at some point.

Future Improvements
  * Potentially subprocess the graphviz generator to allow this to spit out
    graphviz SVG or PNG files!
  * UI that calls this API when you click certain elements.

// This is a module that uses SQLite as a flat-file database to implement a simple key-value store.
//
// Exported methods:
//   get(key, callback)     - Retrieve the value for a given key in the store.
//   insert(key, value)     - Add a key/value to the store. If the key already exists, update its value.
//   getAll(callback)       - Retrieve all values in the database
//   resetdb()              - Reset the database
//
// Since this uses SQLite, it's locking and will likely have scalability issues when many concurrent users are
// accessing the database. Sequelize allows you to replace sqlite with a more production-ready database such
