First of all, as long as you can make good use of Baidu bidding is a good thing, it can be said that all these years, I have been eating this meal Baidu, so I am very grateful to Baidu. This article is not to say that Baidu is not good. It is just a matter of fact. Only by understanding it can we make good use of it.           Here refers to the operation of the account, the other does not say, Baidu bidding in those unknown rules and cat greasy, many, give a few examples to illustrate briefly:         First, click the price formula. Many people know the formula, but who dare...

Linear feedback shift register (LFSR) In practice, the selection of random seeds determines the difference of pseudo-random sequences, which means the selection of random seeds is very important. The most common way to generate pseudo-random numbers is to use a linear feedback shift register (LFSR).nA D trigger and several XOR gatesThe following pictures are made: 　　　　 Where GN is the feedback coefficient, the value can only be 0 or 1, take 0 to show that there is no feedback path, take 1 to show that there is a feedback path; where the feedback coefficient determines the different al...

P1502″ stars Title Description In the evening, Ka looked out from the balcony and said, “Wow, lots of stars.” But he didn’t have a window for the other rooms. The naive Ka always wanted to see the brightest stars at night, but the window was fixed in size and the sides had to be parallel to the ground.
