...eckout -b newX X
git cherry-pick Y..tempZ
(optional) git branch -D tempZ
What this does is to create a branch tempZ based on Z, but with the history from Y onward linearized, and then cherry-pick that onto a copy of X called newX. (It's safer to do this on a new branch rather than to mutate X.) Of...

How many random elements before MD5 produces collisions?

"probability of collision is 1/2^64" - what? The probability of collision is dependent on the number of items already hashed, it's not a fixed number. In fact, it's equal to exactly 1 - sPn/s^n, where s is the size of the search space (2^128 in this case), and n...
