Personally, I am a big anti-fan of the Spaced Repetition.
IMHO it is a wonderful solution to a wrong problem (i.e. memorizing random things). Sure, there are use cases: learning words in a language one is not exposed to on a daily basis or cramming for a medical school exam.
When one actively uses something, there is a natural spaced repetition of the things that matter. With the frequencies as these things are used in practice. Everything else can be looked up later.
For programming, maths, physics, etc - "I forgot" means more or less "it is more time-efficient to google it once a few years than put effort in storing in in my memory". In programming, it is even more the case: libraries, their APIs, and good practices keep changing. Rote memorization may be highly counterproductive in this case.
