How the Environment Changes the Way We Write C++ Code
summary
Argues that “good code” depends on constraints: when heap allocations are forbidden the code uses a fixed-size container (example: static_vector sized for 100 objects) plus std::variant to store mixed types, eliminating runtime new/delete. Shows how multi-level CRTP replaces virtual dispatch and how C++23’s implicit this simplifies it. Demonstrates deterministic recomputability by record component inputs (number every sensor sample, store RNG seeds) so rare bugs that occur once per month can be replayed exactly.
