Episode notes
Time is Essential in Complex Models
- Complex models inevitably require a notion of time to function correctly.
- Accounting exemplifies this as it tracks transactions with timestamped events, not just balances.
Dual Time in Accounting Example
- Accounting uses two time notions: when the event occurred and when it was recorded.
- For instance, transactions from last year can be entered in the books days or months later.
Undo Implies Time Modeling
- Undo actions require modeling the order of operations as time.
- Representing the sequence of changes lets you reverse steps in user interactions.
