Profilers measure the performance of a program at runtime by adding instrumentation to collect information about the frequency and duration of function calls. They are crucial tools for understanding the real-world performance characteristics of code and are often the first step in optimizing a program. Apple and Google have first party profiling tools, but they are only usable for local debugging during development.

The 3-2-1 backup rule is a strategy to ensure your data is recoverable in case of data loss incidents. It recommends having at least: The rule was conceptualized by US photographer Peter Krogh.
