visualization, trending, alerting, & other good things b. Enable threshold-based alerting & health checks iii. Transform logs/events into metrics to enable statistical analysis iv. Adrian Cockcraft – “Monitoring 6. Ch. 18 – Create Review and Coordination Process to Increase Quality of Our Current Work a. Goal – enable Development and Operations to reduce risk before production CHANGES i. Require peer reviews, not external board approval ii. Peer review help improve overall quality, provide cross-training, learning, and skill improvements. iii. Keep batch sizes of reviews small

acts as a catch-all, covering all other cases. Thus, overall, this defines a boolean function that checks whether its two arguments are of the same type: julia> same_type(1, 2) true julia> same_type(1 denominator. Now things get interesting. OurRational has a single inner constructor method which checks that num and den aren't both zero and ensures that every rational is constructed in "lowest terms" Chapter 27 Calling C and Fortran Code Though most code can be written in Julia, there are many high-quality, mature libraries for numerical com- puting already written in C and Fortran. To allow easy use
