Abstraction is a powerful servant, but a dangerous master. We code, design, think, debug ... on a tower of abstractions. Spolsky's Law tells us that "All abstractions leak". This talk explores why they leak, why that's often a problem, what to do about it; I also cover why sometimes abstractions SHOULD "leak", and how best to produce and consume abstraction layers.
