Where Do Libraries Come From?
summary
Most libraries start as accidental reuse of small code that solves a recurring problem and only become libraries once independent projects use them. An HDR Histogram begins as an inner class in a jitter tool, becomes a Java library with eight language ports, records 200 million recordings/sec, tracks microsecond-to-thousand-second ranges with fixed relative precision, and ships a common wire format and concurrent recorders. Portability pains force choices like Java 6–11 compatibility, avoiding multi‑version jars, and using encapsulated helpers and method handles; Java added onSpinWait to support future optimizations.
