How to generate random 64-bit value as decimal string in PHP
Oauth requires a random 64-bit, unsigned number encoded as an ASCII string in decimal format. Can you guys help me achieve this with php?
Thanks

numpy arbitrary precision linear algebra
I have a numpy 2d array [medium/large sized – say 500×500]. I want to find the eigenvalues of the element-wise exponent of it. The problem is that some of the values are quite negative (-800,-1000, etc), and their exponents underflow (meaning they are so close to zero, so that numpy treats them as zero). Is there anyway to use arbitrary precision in numpy?
