Mutex (mutex)The mutex is very similar to the critical section, and only the line that owns the mutex Cheng has access to the resource, and because the mutex has only one, it determines that the shared resource will not be accessed by multiple threads at the same time. The thread that currently occupies the resource should hand over the mutex that it owns afte

Authorization is access control, which determines whether the user has appropriate access to the resource in the application. For example, determine whether a user has permission to view the page, edit the data permissions, have permissions for a button, have permission to print, and so on. I. Three elements of authorization Authorization has three core elements: permissions, roles, and users. Permissions Permissions are the core elements of Apache's Shiro security mechanism. It explic

borrowed 2 yuan from B, so he bought the island with 3 yuan. He used the borrowed $2 in cash and eliminated the $1 debt owed to him to buy a small island from c. B borrowed 2 yuan for a, so his net worth is 2 yuan. C now has 2 1 yuan coins, his net worth is still 2 yuan. The net worth of this country = 5 yuan. Bubbles are gradually building up. 5) b Seeing the value of land rising, he also wants to own land. So he used 4 yuan to buy a land for a, payment is to C borrowed 2 yuan and lift

Generally, only when in the constructor of the main form of the application When a background thread is created (as in Application. Run (new MainForm (), it is created before the form is displayed or Application. Run is canceled. This happens. One solution is to wait until the form handle has been created and then start the background thread. You can call the Handle attribute to forcibly create a Handle or wait for the L

field (This field is incorrectly defined in winnt. H-it should be DWORD ratherHandle) contains the thread ID that owns this critical section. The difference between this field and the value (recursioncount-1) indicates how many other threads are waiting to obtain the critical section. Recursioncount This field contains the number of times that the owner thread has obtained the critical section. If the value is zero, the next thread that attempts to

Controlling companies Control Company Some companies are part owners of other companies because they have obtained a portion of the shares issued by other companies. For example, Ford owns 12% of Mazda's shares. It is said that if at least one of the following three conditions is met, Company A can control company B: Company A = Company B. Company A owns more than 50% of Company B's shares. Company A co

this simple rule: Whenever you write a variable that might be read by another thread, or if the variable you are reading is finally written by another thread, you must synchronize. But now a little better, in the nearest JVM, there is no contention for synchronization (when a thread owns a lock, no other thread attempts to acquire the lock) the performance cost is still low. (This is not always the case; synchronization in the early J
