 20h accepted "Duplicate symbol" with anything less than "-O2" 1d comment EZ-Water - Fraud or breakthrough?The question was first about the existence of this so called "EZ water", way before we get to any health benefits. I think Ben has explained rather well why there is no real reason to beilive such water exists. 1d awarded Critic 1d comment How to prove $\sum_{n=0}^{\infty} \frac{n^2}{2^n} = 6$?+1 Very elegant! 1d comment Fisheye/Wide-Angle lens Calibration in OpenCVwould you mind posting / sharing your code, if you got it to work? 2d asked "Duplicate symbol" with anything less than "-O2" Dec 4 comment Find $x$ such that $\sqrt{x+\sqrt{x+7}}\in \mathbb{N}$+1 for the only complete answer :) Dec 4 answered How to Integerate $\frac{x}{x^2-4x+8}$?
