This week we looked at some very specific behaviours regarding signing up for a
subscription on a fictional Stripe-powered subscription site, using Ports where
needed. For this week's exercise, we'll make the layout simple for people
that aren't fully logged in. First, though: here are some links I've found

If you're a Haskeller (or Haskell-curious?), this is a nice-looking library for

Kent Beck - Mastering Programming
Here are ways effective programmers get the most out of their precious 3e9
seconds on the planet.
Kent Beck is a genius and this is a roll-up of a lot of wisdom. Read it! Not
directly applicable to Elm, but a good generally valuable post regarding
software development practices. A good Elm-y related bit of wisdom from the
Symmetry. Things that are almost the same can be divided into parts that
are identical and parts that are clearly different.
I learned of this post from the Avdi Grimm's weekly Brunch
which I can also highly recommend.

Michael Feathers - Toward a Galvanizing Definition of Technical Debt
Technical Debt is the refactoring effort needed to add a feature

isn't particularly Elm-related, but I found it great and it's definitely worth a

This week's exercise is simple. Just modify the elm_web_components_playground
in a pretty minor way:
- If the user is not logged in or has no subscription, just center the content
and exclude the drawer from the layout entirely.
- If they are logged in with a subscription, nothing should change.
It's a surprisingly easy exercise this week, because I'm full of Christmas food
and cheer. See you soon!
