This question is seldom met, but the answer is of course not.Atomic added a lock in the set method, preventing multi-threading from writing to the property, causing difficult-to-predict values. But it's also just a read-write lock. and thread safety is actually worse. Look underneath. @interface monperson: nsobject @property (copy) nsstring * firstName; @prope

In recent times, there has been a lot of discussion about creating "Keylogger" (keyloggers) through CSS.Some people call on browser makers to "fix" it. Some have studied in depth, saying it only affects websites built through the React framework and accuses React.

is the session in PHP safe?

When you feel a virus in your system, the first reaction is to try anti-virus software. If you want to quickly determine the security status of the current system, you can use several commands in the "command prompt" to check whether the system is poisoned. The speed is far higher than that of anti-virus software. TIPS

The difference between synchronous code block and synchronous method: Synchronous code block can pass in arbitrary object, synchronous method if more than one thread examines a new object, different synchronization locks are not exclusive to different threads, cannot realize thread synchronization effect, then thread synchronization fails.The difference between the two is mainly reflected in the synchronization lock above. For the synchronization meth

A function, even if it is of type bool, but we can return the int type, and automatically convert 0 to false , non-0 converts into true . The code example is as follows:#include however, in Java , we can't use it that way, Java can't do it. int type Go BOOL type,

What is thread-safe and non-thread safe?Thread safety is the case that there is no data inconsistency in a multithreaded environment, and there is a risk of inconsistent data for non-thread safety.Thread safety controls the read a

People with C + + development experience will find that we can use 0 as false, not 0 as true.

thread safe and does not carry out thread security checks at execution time. Then look at the two ways PHP executes: ISAPI and FastCGI. ISAPI execution is in the form of DLL Dynamic library, can be executed after the user request, after processing a user request will not disappear immediately, so the need for thread security checks, so as to improve the efficiency of program execution, so if you are usin
