- Does code minification change how a program behaves?
- A correct minifier preserves behavior, but aggressive transformations can expose assumptions in fragile code. Keep source control and test the minified artifact in its target environment.
- Why can DNS results differ between resolvers?
- Caching, geographic routing, resolver policy, DNSSEC validation, and propagation timing can produce different answers or TTLs for the same name.
- Are generated card numbers real payment credentials?
- No. They are checksum-valid test values only and do not include a funded account, authorization, or security code tied to a financial institution.
