Hi Mark,
Factor was not designed with multiuser Windows systems in mind. It would be
best to have each user install their own copy of Factor in their home
directory. We could try to fix all of the problems for .98 if make a list
of them in an issue on github.
For the second issue, are you using .96 or the latest download? Factor .96
initialized the Mersenne Twister PRNG with a number from the system PRNG.
Lately, it's been changed to initialized from the ``nano-count`` word and
the latest Win64 download contains the new code. However, we still
initialize a system PRNG and a secure PRNG, but those are supposed to
initialize to ``f`` if the system calls fail. We don't explicitly create
keys, the system calls do that I guess.
The code is at
https://github.com/slavapestov/factor/blob/master/basis/random/windows/windows.factor
if you have any suggestions on what to change.
I would love to fix any problems you find as the course progresses if you
decide to teach Factor.
Cheers,
Doug
