Dep Protection Principle

). The software DEP is actually the safeseh we introduced earlier. It aims to prevent the use of s.e. h attacks. This mechanism has nothing to do with CPU hardware. Windows uses software simulation to implement DEP, which provides some protection for the operating system. Now everyone understands why the exception handling function is located on a non-executable page during the safeseh verification process. Hardware DEP is the true dep. Hardware Dep requires CPU support. Both AMD and Intel h

Frequency domain representation of reduced sampling

The frequency domain representation of the subtraction sample can be viewed from two angles:1. Directly from the original signal point of view, this needless to say, according to the new sampling frequency of the original signal spectrum directly normalized to the digital domain on the line;2. From the existing spectrum perspective, can be introduced (refer to discrete-time signal processing):Xd (ejω) = (1/m) Sigma (i, 0:m-1) X (EJ (ω/m-2πi/m))

If you want to ignore case when looking, you can write pattern p=pattern.compile (regex,pattern.case_ins

Improve performance in XML applications, part 1th

improve performance by reducing the number of new rows and spaces in the document. Typically, for editing purposes, developers organize documents into rows-for example, by using carriage returns (#xD) and wrapping (#xA). The XML parser must convert the two-character sequence #xD #xA and all #xD (not followed by #xA) to a single #xA character. This conversion is
