Is there an MD5 Fixed Point where md5(x) == x?
...ng. Assuming that the MD5 sum of any string is uniformly distributed over all possible sums, then the probability that any given 128-bit string is a fixed point is 1/2128.
Thus, the probability that no 128-bit string is a fixed point is (1 − 1/2128)2128, so the probability that there is a fixed ...
Is floating-point math consistent in C#? Can it be?
...to way to make normal floating points deterministic in .net. The JITter is allowed to create code that behaves differently on different platforms(or between different versions of .net). So using normal floats in deterministic .net code is not possible.

...aracter range, therefore highlighting (assuming you have hlsearch enabled) all other characters lying outside the ASCII range:
/[^\x00-\x7F]
This will do a negative match (via [^]) for characters between ASCII 0x00 and ASCII 0x7F (0-127), and appears to work in my simple test. For extended ASCII,...

Overriding id on create in ActiveRecord
...why you can't use mass-assignment to set it. However, when setting it manually, it just works:
