removing artificial barriers that have made the accidental tasks inordinately hard, such as severe hardware constraints, awkward programming languages, lack of machine time. How much of what software engineers desperate cries for a silver bullet – something to make software costs drop as rapidly as computer hardware costs do…. Not only are there no silver bullets now in view, the very nature of software makes breakthrough promises to give the sort of magical results with which we are so familiar in the hardware area, we must consider those attacks which address the essence of the software problem, the formulation

Enabling two or more disparate entities to work together.Why interoperability? No language or platform is good for everything. Fast inner loop Makes UX easy Has tooling for workload High performance Simplified Wrapper and Interface Generator (SWIG) – 1996 JVM – Java Native Interface (JNI) – 1997 .NET – Platform Invoke (P/Invoke), COM interop, C++/CLI – 2002, 2005 JVM – Java Native Access (JNA) – 2007 Go – scenarios with a Garbage Collector (GC). 1. Handles – Level of indirection. • Usually requires a “platform” API to use the memory. • .NET has GCHandle. • JVM, through JNI, exposes most memory as a handle
