edge-triggered programming

examples

• producer/consumer
• publisher/subscriber
• observer
• event

take away

• work well in a single process
• tends not to work so well in distributed systems, due to Fallacies of distributed computing
• when bad things inevitably happen,you drop back to a level-triggered mechanism that reconcile discrepancies in state
• it’s ok to use, but think in it
