    Are we seriously benchmarking programming languages based on the number of syscalls Hello World takes now

        I wish people creating these things realized that all they're doing is creating make-work for compiler engineers, making them work on vanity metrics instead of actually useful features.

        So I actually strace'd hello world in Rust. Most of the syscalls are just from http://ld.so , and so could be eliminated with static linking if you cared. The remainder are for stack guards, which are an important security feature.

        Publishing benchmarks like this just encourages language runtimes to not do important things like set up stack guards, harming safety/security. It's irresponsible.

        From the guy who brought you “Go is the result of C programmers designing a new programming language, and Rust is the result of C++ programmers designing a new programming language” while glossing over the part where one has a garbage collector and the other doesn’t?

        More like from the person who brought you “‘Efail’ is a very stupid ‘vulnerability’ used to smear PGP by jerks with ulterior motives.”

        That's "streetlight benchmarking" (looking for lost keys under the streetlight, because it is bright there; not where they were actually lost): it is easy to benchmark, therefore it is important! Narrator: deep down he thanked all gods it was not Fibonacci again.

        We do need alternative metrics. I nominate "how many functions with an 'e' in their name are called during execution"?
