William Carroll 9d331f3077 Begin working on Habit Screens project
Created a small MVP for digitizing my weekly habits. Much more to come.

Lots of things happening:

- Copied the boilerplate to get started
- Added a brief project-level README
- Outlined my ambitions in design.md

See README and design.md for more context on this project.

Habit Screens

MVP

One Android tablet mounted on my bedroom wall displaying habits for that day. I can toggle the done/todo states on each item by tapping it. There is no server. All of the habits are defined in the client-side codebase. The application is available online at wpcarro.dev.

Ideal

Three Android tablets: one mounted in my bedroom, another in my bathroom, and a third in my kitchen. Each tablet has a view of the current state of the application and updates in soft real-time.

I track the rates at which I complete each habit and compile all of the metrics into a dashboard. When I move a habit from Saturday to Sunday or from Wednesday to Monday, it doesn't break the tracking.

When I complete a habit, it quickly renders some consistency information like "completing rate since Monday" and "length of current streak".

I don't consider this application that sensitive, but for security purposes I would like this application to be accessible within a private network. This is something I don't know too much about setting up, but I don't want anyone to be able to visit www.BillAndHisHabits.com and change the states of my habits and affect the tracking data. Nor do I want anyone to be able to make HTTP requests to my server to alter the state of the application without my permission.

Client

Language: Elm

Updates across devices

Instead of setting up sockets on my server and subscribing to them from the client, I think each device should poll the server once every second (or fewer) to maintain UI consistency.
