View Card →What is the best default for runtime patching?
Choose the simplest shape that keeps the rule explicit, testable, and easy for the next engineer to read.…
View Card →How should you explain runtime patching in an interview?
Use patching in tests or controlled seams, but do not let it become the architecture of the production…
View Card →What is the main pitfall around runtime patching?
Heavy runtime patching can hide dependencies and make behavior difficult to reason about. Naming the pitfall early helps…
View Card →What is the core rule behind runtime patching?

View Card →What does good reference counting and gc code look like?
It is explicit about the rule, honest about the data shape, easy to test, and easy to explain…
View Card →What is the next improvement after the first working version of reference counting and gc?
Clarify one boundary, add one focused test, and remove one avoidable ambiguity. Small improvements that directly reduce risk…
View Card →What anti-pattern should you watch for with reference counting and gc?
Using the feature to compress code while making the rule harder to test, debug, or explain. Compression is…
View Card →What does a good verbal answer about reference counting and gc sound like?
Clear, concrete, tradeoff-aware, and tied to one real workflow or bug pattern. Interview answers improve when they sound…
