Decision-Making: An Experiment

Participant Instructions

Let's play a game.

The aim is to have the most points at the end of the game.

On every turn of the game, you can either:

  • Lose 1 point and take a card. A card is worth points.

In Lisp, we use brackets to determine where an expression starts and ends. This looks weird and adds a lot of cluttering brackets. Can we get rid of them?

Suggestion: Each form has an arity (which can be *); the parser uses left-to-right parsing to determine where an expression starts and finishes.

Let's assume + is a 2-form, and numerics are values (1-form):

+ 2 2     # => (+ 2 2)

Techniques

  • #5: Products over Projects is an important terminology change that reflects what we're doing in the development team more and more.
  • We should be aware of avoiding #26 Microservice Envy and #30 Seperate DevOps Team for the future.

Platforms

Why?

  • It's fun.
  • It's useful.
    • Knowledge of how languages work is useful when you hit a really weird bug.
    • It gives you an appreciation of how languages are designed for the use case. It reduces WTFs.
  • I can say I've built a programming language; looks great on the CV!
  • It lets me experiment - are there features that could be better? Is there a combination we haven't tried?
  • It's hard. I like hard challenges.

What is SOLID?

Requirements always change. We need to write code that is able to change in the future. The process of doing so is usually called design. Design principles are often-cited rules that lead to easily-changed code. Design principles have been derived from the initial goal: to have easily-changed code. They are not arbitrary rules. SOLID principles are an often-used set of design principles.
