Inspiration: What is the most important thing in a person's life? When a person is doing a good thing, other people may consider whether it is worthwhile to do so. Is there any return for this kind of payment? However, these are not important. A person who

During the war, Cao occupied the wife of Qin Yilu, a general under Lu Bu. This time, he angered Guan Yu, who liked Mrs. Qin as well. He chose to leave Cao and killed five defenders. There was also an unconfirmed rumor that he was even interested in Joe and John, and started to do so. The war of aggression against the US-just like the victory of the wall of the T

Concrete Mixing tower (Station) management and cost accounting 1) how to manage production? How to confirm the actual concrete mix ratio of the sub-item WBS? 2) how to determine the planned cost of concrete? How is the actual cost calculated? Cost consideration: is it a full cost or only focus on the cost of concrete materials? 3) I think: the number of difficult problems ranks first! Professional personnel are welcome to provide solutions! 1) Mixing floor (Station) Management Self-productio

first digit 7 in 765 indicates that the owner has the R + W + x permission (7 = 4 + 2 + 1 ), the second number 6 indicates that the same group has the R + W permission (6 = 4 + 2 ), the third digit 5 indicates that the other person has the R + x permission (5 = R + x ). Usage: chmod 765 file name You can change the number to the required permissions.

file also has to be a regular file. The file access tests that the Kernel performs each time a process opens, creates, or deletes a file depend on the owners of the file (St_uidAndSt_gid), The valid IDs of the process (valid user ID and valid group ID), and the supplementary group IDs of the process, if supported. the two owner IDs are properties of the file, whereas the two valid tive IDs and the supplementary group IDs are properties of the process. the tests saved med by the kernel are as

storesOwnership indicator. An object constructed with a non-null pointer owns the pointer. It transfers ownership if its stored value is assigned to another object. The Destructorauto_ptrDeletes the allocated object if it owns it. Hence, an object of classauto_ptrEnsures that an allocated object is automatically deleted when control leaves a block, even via a thrown exception. // Well, it is estimated that

,Characteristics of timed lock wait and interruptible lock wait. In addition, it provides better performance in the case of fierce competition. (In other words, when many threads want to access shared resources, JVM can spend less time scheduling threads and spend more time on execution threads .) What does the reentrant lock mean? To put it simply, there is a lock-related acquisition counter. If a thread that owns the lock gets the lock again, it wi

thread ID, and a counter.The   ID is used to identify which thread in the system has a mutex object. The counter is used to specify the number of times that the thread has a mutex object.The correct example of using mutex objects for multi-thread synchronization in zookeeper is as follows: # Include Execution result Zookeeper tests show that the introduction of the mutex object can solve the problem of resource synchronization between threads. The following questions about mutex objects

name10. There are three types of file permissions:A. File owner: the user who creates the fileB. users in the same group: any user in the user group that owns the fileC. Other users: a user who does not belong to the user group that owns the fileFor example,-rwxr-xr-x 1 root 217 08-10 test1.shThe first character indicates the type of the file, whether it is a folder or a common file example-indicates a com

In the previous article, Mutex is an exclusive lock. Only one thread can own the lock, and it is the same thread immediately. If a Mutex is already held, it will still block the attempt to obtain the lock again. Sometimes we need to lock the same thread as the Java synchronized to re-enter, as long as it already has the lock, instead of blocking it. We can transform the implementation of Mutex in the previous article to implement a reentrant lock-ReentrantLock. This requires ReentrantLock to rec
