Ring oscillators (more specifically, XOR or other mixing operations between at least two oscillators) are a good basis for a TRNG. I've implemented one of my own (source code now lost :() : https://emergent.unpythonic.net&#

eh, not so accurate. it's true that you can't have int i; and write i++. but neither do you need a mutex. for instance, you may just need std::atomic<int>, which (except on a very unusual system) is not going to be implemen

May I suggest to call it GNU, for "GNU is not Ubuntu".

Thanks, my first question was exactly the one you answered: "is the proposed mechanism within an order of magnitude of explaining the observed thrust?" It sounds like it's not.

Ah, I can see that I wouldn't necessarily get a very good result if I'm actually doing calculations with a 16-bit mantissa.

Hi, thanks for sharing your implementation. Am I totally misusing (py)unum? Using pyunum, repeatedly rotate the point (1,0) by 45 degrees. Print out the X coordinate every 8 rotations. Mathematically, the value printed each time should

Bare metal aarch64 code can be run on the pi3, so while the binary boot blob is a big burning ball of shame, it is not what prevents an aarch64 kernel for the pi3. Rather, it looks like a matter of an expert investing sufficient time. ht

It looks like all collections store void pointers. I don't see any abstractions to help with pointer lifetimes, which remains the main problem I encounter when trying to write large programs in C that dynamically allocate memory.
