For the purpose of stable utilization, it is required that the selected Gadget address be fixed. No matter when it is, it directs to the desired command. The concept of ASLR is introduced here. The full name of ASLR is Address Space Layout Randomization, that is, Address Space pattern Randomization.

Why use tostringbuilder? Generally, logs must be printed in the system, because the tostring () method of all entities uses a simple "+", because every "+" method creates a new String object, in this way, if the system memory is small, the memory will be v

operations on its properties. It should be noted that although we are creating this class, it is nothing special and it does not inherit or implement any of the basic classes. The requirements for a sustainable class are: 1. All domains must be able to be accessed by the JDO class (public or Set* method) 2. The data type of the domain must conform to the JDO specification. 3, can not support some types of fields (such as thread, File, socket, etc. can not be serialized fields). Below are the Pe

In modern compilers, to prevent users from constructing data through buffers on the stack, a DEP mechanism, which restricts memory properties, makes some writable memory non-executable (such as a stack), or can perform memory not w

Quick sorting is an in-situ sorting algorithm. Its Worst run time is N2, the expected run time is nlgn, and the hidden constant factor is small. Therefore, quick sorting is usually the best practical choice for sorting. Section 7.3 describes a randomization deformation of quick sorting. The average running time of this version is good, and there is no special input that will lead to the worst running status. 7.1 description of fast sorting Like mergin
