Hadamard transform
Haar  Trous Wavelet decomposition of the real crude oil volatilities

In the last blog entry ive mentioned the hadamard transform, so its high time to dissuss it
the hadamard transform is a linear transform, and all linear transforms can be written as a vector-matrix multiplication, here the matrix is orthogonal, symmetric and all it elements are either a or -a. Actually this is commonly written as a matrix of 1 and -1 which is multiplied by a which is sqrt(size of the transform), you also might want to take a look at Wikipedia/Hadamard_transform.
The hadamard transform is also somewhat similar to the DCT but simpler, thats also why its used as part of a SATD motion estimation comparission function, the dct would be slightly better quality wise but significantly slower …

That is a misunderstanding of Biblical prophecy
the antichrist will not have a 7 year reign, this is commonly referred to as the 'seven years of tribulation'. find that phrase for me in the Bible- it doesnt exist.
it is a misunderstanding of the 70 weeks prophecy located in Daniel 9:24-27. the Jews have placed a talmudic curse on anyone that attempts to calculate the numbers give in these verses because it proves that Jesus was the Messiah. It proves the date He would come, how long His ministry would last, and that He would be crucified 3 and 1/2 years into His ministry.
today, prevalent in theology (read that, Jesuit theology-- which has slithered its way into protestant seminaries ((preterism/futurism))) has come up with the idea that the last 'week' (7 days, or,...

Someone here might gain something from it. It is true.
For the past week I have had prolonged bouts of crying. I have not been able to sleep or eat and didnt answer the phone. What would cause this? Death in the family? Losing the house? Cancer diagnosis? Not at all.
My depression has been over the stock market. Not over how much money I've lost, but rather how much money I would have made had I not sold my stock. I invested 50% of our money into it so we're not talking chump change. It would have been enough to buy a house, more as it continues to climb.
Now I am not normally an emotional person. Prior to investing in the markets, I maybe would cry 1-2 times a year and always for a reason. I have a good life with no money worries, loving husband, my health, etc. but I...

Good afternoon. Let me begin by saying that although this has been billed as an anti-war rally, I stand before you as someone who is not opposed to war in all circumstances.
The Civil War was one of the bloodiest in history, and yet it was only through the crucible of the sword, the sacrifice of multitudes, that we could begin to perfect this union, and drive the scourge of slavery from our soil. I don’t oppose all wars.
My grandfather signed up for a war the day after Pearl Harbor was bombed, fought in Patton’s army. He saw the dead and dying across the fields of Europe; he heard the stories of fellow troops who first entered Auschwitz and Treblinka. He fought in the name of a larger freedom, part of that arsenal of...
