source code leakage, ASP pages can be encrypted. There are two methods to encrypt ASP pages. One is to use component technology to encapsulate programming logic into DLL; The other is to use Microsoft Script encoder to encrypt ASP pages. However, the main problem with the use of group component technology is that each segment of code must be componentized, so the operation is cumbersome and the workload is heavy ; the script encoder is used to encrypt ASP pages, which is simple and effective.

a generator: def gen(): a = 2 yield a a = a * 2 yield a yield 1024The generator has three yield instances. If it is used as a loop generator, it performs three cycles. for i in gen(): print i Let's look at another generator: def gen(): for i in range(4): yield iIt can be written as a generator expression: G = (x for x in range(4))Generator expressions are a simple way to compile generators.

case, this is the case. For each training sample X, some sampling method is used to extract a corresponding sample that conforms to the molar distribution represented by the RBM Network (which means that the sample that complies with the parameter-determined molar distribution p (x), for example, Y; for the entire training set {x1, x2 ,... For XL}, we obtain a set of samples {y1, Y2 ,..., YL}, and then use this group of samples to estimate the second

, the operation is simple and the results are good.The Script Encoder method has many advantages:1. HTML is still editable. Script Encoder only encrypts the ASP code embedded in the HTML page, and the rest remains unchanged, this makes it possible to use common webpage editing tools such as FrontPage or Dreamweaver to modify and improve the HTML part, but not to modify the ASP encrypted part. Otherwise, the file will become invalid.2. Easy to operate. Just master several command line parameters.
