I'm getting in a groove stubbing out PRs for gratipay/gratipay.com#3994. I'm seeing a few layers, which aren't unique to us but for which I'm dialing in on some terminology:

1. UI—text/html in simplates, plus CSS and user-facing JavaScript
2. API—application/json in simplates, plus server-facing JavaScript
3. plumbing—Python and SQL, the two are pretty tightly coupled for us

Design from the outside in, build from the inside out. I'm finding that it makes sense to batch Python and SQL changes together into a single PR, and also that it makes sense to batch together API and UI changes together. So maybe (1) and (2) should be folded together?

E.g. "plumb payroll" means "write the SQL and Python necessary to support basic payroll functions. So then maybe "finish payroll" could mean implementing the API and UI ... or even "porcelain payroll" to press the plumbing metaphor a la Git.

TIL

abstract base class

Abstract base classes complement duck-typing by providing a way to define interfaces when other techniques like hasattr() would be clumsy or subtly wrong (for example with magic methods). ABCs introduce virtual subclasses, which are classes that don’t inherit from a class but are still recognized by isinstance() and issubclass(); see the abc module documentation. Python comes with many built-in ABCs for data structures (in the collections module), numbers (in the numbers module), and streams (in the io module). You can create your own ABCs with the abc module.

Excellent to the end.
