Agree. Well, maybe stating, that RNGs, hash functions (and XOR ;) are just building blocks and tools to build true functionality out of them, would help. I see

Agree. Well, maybe stating, that RNGs, hash functions (and XOR ;) are just building blocks and tools to build true functionality out of them, would help. I see it quite similar to statistics. Yes I do know and understand mathematical operations, "numbers" and some statistical operations like average, median and maybe even variance but no way I'm capable to setup a proper statistical trial or analysis. I tend to fall back to: describing what I'd like to achieve with what kind of properties of the result and let ppl really knowledgeable on the topic find the correct keywords, tools and in the end algorithms. But boy is it tempting to just mash some hash functions together based on some actually quite naive understanding of their properties ;)
