How to make things easy

Bring to hand by installing
Become familiar by learning and trying
This hurts mental capability

• We are limited(in time and capacity) in the number of thing we can learn

• Not going to move very far

• Makes things near by simplifying them
  Simplicity Tookit

• immutable values

• stateless functions

• namespaces

• declarative data manipulation

• rules

• queues

• consistency
  Environmental complexity that cannot be avoid

• Shared resources : Memory : garbage colletor issues, CPU: threads complexity

• Segmentation generate wates - something that might be used gets unused.

• Individual policies don’t compose

  • Individual good decisions together might not be a good decision at all.

• Abstraction for Simplicity vs Abstraction as complexity hiding.

• Order

  • intertwine one thing with the next
  • inhibits change
