When the receiving end is faster, the receiver is asleep most of the time, and the receiver wakes up when there is new data on the sender side. The cost of this lossless operation can be minimized.

Volatile in Java does not guarantee thread safety (example explained)Reprinted 2017-09-04 Think-007 I want to commentThe following small series to bring you a piece of Java in the volatile can not guarantee thread safety (the example explained). Small series feel very good, now share to everyone, also for everyone to make a reference. Follow the small part together to look at it today hit the code to see if

Developers who go from iphone to Mac will naturally assume that NSView's subview (or controls) have Z-order, but Apple does not guarantee that Subview is displayed in the order in which they are added. There is no Bringsubviewtofront method similar to UIView in NSView.There should be no intersection between Subview. But since I was turning my iphone project into a Mac, I didn't change much like that. The solution was found. is to use the following met

amount of task assigned by each thread cannot be fixed, and the order of the results of merging each thread is not fixed.This leads to the order of the final query results is not fixed.This is an example of the amount of task allocated per thread for a parallel query. , the current query, the number of rows returned by the first thread is 2, but the number of rows returned by the first thread of the second query is not guaranteed to be 2.Even if the number of rows returned is 2 for the second t

See a friend in the forum ask, how can you guarantee that in the MDI main form, a subform of the same type can only be opened once, and then open just to activate the form that was originally opened. This request I have encountered before writing a program. The basic ideas I have achieved are: Typically, each subform inherits from the form type, different subforms represent different functions, so you just need to determine if there is a subform type

The following is an example of a total atomicity implementation by using volatile:The final result of the variable number is calculated by creating 100 threads.

Does the iphone have an inlet warranty? The water is divided into mild and heavy, if your iphone device is flooded, so do not tell the other party can mix, this we see how the official detection. The iphone will be in the headphone hole, data interface, internal motherboard and other places to paste discolored paper, once the mobile phone water, these stickers will change color, once discoloration, Apple after the sale of personnel will think that this is man-made damage, not in the scope of t

Information security system is the guarantee of enterprise business sustainable development, to a certain extent, the construction mode of security management platform (SOC) embodies the idea of building the information security system, because the user can directly operate and see the security management platform. First, the construction of the SOC idea: "Vase" model From the functional development of SOC can be divided into three dimensions: prote

synchronous mode, there are 3 states to ensure that the message is in safe production, in the configuration of 1 (only to ensure that the write leader success), if just leader partition hang, the data will be lost.There is also the possibility of losing the message, that is, when using asynchronous mode, when the buffer is full, if configured to 0 (without receiving confirmation, the buffer pool is full, emptying the buffer pool of messages),The data will be discarded immediately. Ways to avoid

Only by looking at the boost source code can we figure out what happened. First, I write data into the vector, and then use boost: ASIO: buffer to construct the vector into a mutable_buffer_1 object. Refer to the document's heavy duty form:

Cookies exist on the client side, not related to the server, note the case of your program, Linux is case-sensitive, and the configuration of the PHP tutorial, such as whether register_globals = OFF configuration on both sides of the same and so on.

The user sensitive data in the company database needs to be encrypted into binary ciphertext in the MySQL BLOB Type field, now found to ensure the uniqueness of user data is not good, because the Blob type field does not seem to be directly logical

I search on Google for some of the user authentication program for the app, but also compared to the traditional PC era of cookie authentication, I think it is not reasonable, I think of a solution, do not know whether it is reasonable? This is
