Dishwasher Salmon
Summary: The Dishwasher salmon is a fish dish made in the United States using the heat from a dishwasher, particularly from its drying phase. Pieces of salmon are spiced and wrapped tightly in at least two layers of aluminum foil and put in a dishwasher. Depending on the model of the dishwasher, the salmon is broiled, steamed, and baked. The dish was first demonstrated by Vincent Price in 1975 and has been featured in various publications and shows. An advantage of the method is that the prepared dish does not smell.

Efficiency trades off against resiliency
Summary: The article discusses the tradeoff between efficiency and resiliency in technical systems. While it may seem intuitive to aim for 100% CPU utilization to avoid wasting resources, running at full capacity leaves no room to absorb unexpected bursts of traffic or additional workload. This tradeoff applies to redundancy as well, where spare capacity must be held idle in steady-state to absorb incremental load from a failed-over instance. Similarly, sophisticated performance optimizations often rely on specific assumptions, making the system less resilient to change. The article notes that while win/win situations are possible, past a certain level of effort, tradeoffs must be made.
