- What is the capability delivery mechanism in Linux
- The inheritance of the capability mechanism in Linux means that when a process creates a child process, the child process can inherit the capability permissions of the parent process. In Linux systems, the capability mechanism is a more fine-grained permission control method that allows processes to only have certain permissions instead of all permissions. The original intention of this mechanism is to enhance the security of the system and reduce the administrator's burden of permission management. In the traditional Linux permission model, the permissions of a process are determined by

- Use brute force to solve bubble sort
- Bubble sort is another classic manifestation of the brute force method. Algorithmic idea: Compare adjacent elements in the list, and if they are in reverse order, swap their positions. After repeating it many times, the largest element is ranked last. The second operation moves the second element to the penultimate position, and the comparison continues until after n-1 times, the entire list is sorted. The following is my code implementation: C++#includeusingnamespacestd;intmain(){inti,j,temp,N;cin>>N;int*Arr=newint[N];for(i=0;i>Arr[i]

- Using brute force to solve selection sorting problems
- The brute force method is a simple and straightforward way to solve a problem, often based directly on the description of the problem and the definition of the concepts involved. Selection sort idea: At the beginning of selection sort, scan the entire list to find the smallest element, then exchange it with the first element, and put the smallest element at its final position in the ordered list. Then we scan the list starting from the second element, find the minimum value of the last (n-1) elements, swap it with the second element, and put the second smallest element at its final position in the list. Generally speaking, when scanning the list for the i-th time (the value of i ranges from 0 to n-2), the algorithm looks for the smallest element among the last (n-i) elements, and then exchanges it with Ai, in ( After n-1) passes, the list is sorted.

- Operating system FAQ~
- 1: Explain the typical reasons why a process transitions between three basic states (1) A process in the ready state, when the process scheduler allocates a processor to it, the process changes from the ready state to the execution state. (2) If a process being executed is deprived of the processor to suspend execution because the time slice allocated to it is used up, its state will change from the execution state to the ready state. (3) If something happens that blocks the execution of the current process and makes it impossible to continue execution, the state of the process changes from execution to blocking. 2: Why should threads be introduced into OS? What are the benefits of introducing threads? (1) Since the process is the owner of the resource, large time and space overhead is required in the creation, cancellation, and switching operations, which limits the further improvement of the degree of concurrency. to reduce
