| * [[Easy to Use and Hard to Misuse]] (EUHM): Because of ML an interface should be crafted so it is easy to use and hard to misuse. EUHM is the application of ML to interfaces. | * [[Easy to Use and Hard to Misuse]] (EUHM): Because of ML an interface should be crafted so it is easy to use and hard to misuse.

| * [[Uniformity Principle]] (UP): A typical source of mistakes are differences. If similar things work similarly, they are more understandable. But if there are subtle differences in how things work, it is likely that someone will make the mistake to mix this up. | * [[Uniformity Principle]] (UP): A typical source of mistakes are differences.

| - | * [[Invariant Avoidance Principle]] (IAP): Invariants are statements that have t be true in order to keep a module in a consistent state. ML states that eventually an invariant will be broken resulting in a hard to detect defect. IAP states that invariants should therefore be avoided. So IAP is the application of ML to invariants. | + | |

| - | * **[[Fail Fast]] (FF)**: Sometimes it is impossible to actually prevent an error. In such a case it is advisable to fail fast so the error is recognized early. | + | * **[[Fail Fast]] (FF)**: Sometimes it is impossible to actually prevent an error.
