C++ in the Cloud One NIF at a Time with Elixir Sakshi Verma | Senior Software Engineerhttps://www.linkedin.com/in/sakverma Functional, concurrent language built for scalability. Ideal for managing shared library Loaded into Erlang VM at startuphttps://www.linkedin.com/in/sakverma Why Write a NIF? Erlang/Elixir ≠ CPU-heavy tasks. 01 Direct hardware interaction. 02 Interop with graphics com/in/sakverma NIF Code: A Closer Lookhttps://www.linkedin.com/in/sakverma #include nif.h> #include ERL_NIF_TERM xgboost_build_info(ErlNifEnv* env, int argc, const ERL_NIF_TERM argv[])
