What are the best programming certificates for QF (besides those offered on QuantNet)?

[Quavid]

Hey guys,
I am looking for good opportunities to enhance my programming in order to get into QF. What are the best certificates besides those on Quantnet to do so?

There's no better C++ online course(s) than Quantnet/Baruch. At least, I haven't found one.
