controller game host Wii,sony in September 2010 launched a high-precision dynamic body sensing controller PlayStation Move, Microsoft on November 4, 2010 launched the XBOX360 gaming console peripheral Peripherals Kinect. Kinect completely abandons any outside device, and in a revolutionary way, interacts with the physical sense of the player's life. Not only can identify the player's body movements, but also can identify the player's voice, as Micros
operation.[PURPOSE]Now we have made a design to ensure high availability and high-performance access to the data quota, and of course ensure data accuracy.Solution:Design a table that exists on the central server and has the freeze quota and credit limit balance fields (of course there are other basic information ). the operation on the quota of the Business Server is completed on this cluster. the data process is described above.When a Service Server fails, it immediately switches to another s
A list needs to be displayed during project creation, but the header must be frozen when there is too much data to be rolled, so I wrote the following script (I once found the corresponding script on the Internet, but it is not ideal, so I wrote it myself. But currently, because the project only uses the freeze of the header, you do not need to specify column freezing, so currently you can only calculate an incomplete script, but generally you only ne

Store thread objects in the thread pool at the same time.Notify: Wakes one of the waiting threads in the thread pool.Notifyall: All threads in the thread pool are awakened.Attention:1: These methods need to be defined in synchronization.2: Because these methods must be marked to belong to the lock.You have to know that the thread of a lock is wait, and that thi
[JS] [easyui] Simple Analysis of jQuery EasyUI Datagrid VirtualScrollViewZookeeper
We all know that the advantages of the EasyUI Datagrid component in loading large data volumes are not very obvious. Compared with other frameworks, if the data volume reaches several thousand, it will be slow, especially under IE. To solve this problem, we first need to optimize the performance of the datagrid component. However, everything can be changed. virtualScrollView is a good solution.
The principle of vi
have been encapsulated into the memory. This object isObject of the class bytecode File.
So only one object exists during static loading, so this object is used by the static synchronization function.
This object isClass Name. class
What is the difference between a synchronous code block and a synchronous function?
1. The lock used to synchronize code blocks can be any object.
2. The lock used by the synchronous function is this,
3. the lock of the static synchronization function is the bytec

The ideal state of system hibernation is that all tasks are not aware of the hibernation process, and all automatically resume work after waking up, but some processes, such as a process that requires all CPU online to function properly, will work abnormally during hibernation if the process
