I am an Assistant Professor at the Mathematics Department of the University of Colorado in Boulder.
My mathematical work has been in Set Theory (almost disjoint type families) and Computability theory (effective randomness and reverse mathematics).
Right now I am preparing for a career change towards information technology. I feel I have worked enough on foundational questions in mathematics, and am ready for new challenges.
# memoized fibonacci function
fibtable = {1:1, 0:1}
def fib (n):
global fibtable
if n in fibtable.keys():
return fibtable [n]
val = fib (n-1) + fib (n-2)
fibtable [n] = val
return valrather contrasts with
"The next big difference is that we changed colors and went from cardboard to white to spark the interest of people walking by instead of automatically having negative associations that they have with cardboard and homeless people."
The second can (and in the context of the article maybe should) be tested. The small change is to make exactly the same text on the different material.
The documentation for py-bcrypt ( http://www.mindrot.org/projects/py-bcrypt/) doesn't explain what happens, but shows use is very very easy.
EDIT: current guess is that searching for the salt that was used might be part of what makes it hard.
