The legacy languages — be it ASM or C still rule in terms of performance. Considering all aspects and needs of current enterprise development, it is C++ and Java which outscore the other in terms of speed. Though I have spent the last ~17 years (In 2021) of my life coding and perfecting my Java and J2EE skill — I suddenly feel.

Kevlin Henney and I were riffing on some ideas about GitHub Copilot , the tool for automatically generating code base on GPT-3’s language model, trained on the body of code that’s in GitHub. First, we wondered about code quality. We know how to test whether or not code is correct (at least up to a certain limit).

Basis path testing in software testing is a white box method where the tester examines the codebase to identify all possible paths that could be taken by the user to achieve their aims. These paths are then written as test cases to ensure all the different identified scenarios in the main branches are covered.
