November 15, according to foreign media reports, Sun announced in Friday, the company will lay off 15% to 18%, about 5000 to 6000 people.
At the same time, Sun also reorganized the software business, dividing it into three major divisions: the Application Platform Software division, the System Platform division and the cloud Computing and developer Platform Division.
Among them, the application Platform Division is mainly responsible for Java, MySQL
The phaser is a more resilient synchronization barrier. As with the sync barrier, a phaser allows a group of threads toThe barrier waits until the last thread arrives and the threads continue to execute. Phaser also offers and barrierAction-equivalent operation.Unlike synchronization barriers, which have a fixed number of threads, a
This article is a summary of the study of the article on the network, thank you for your selfless sharing.JDK 1.7 Adds a new tool to Phaser,phaser's functionality with The Countdownlatch is partially coincident.The following uses the Phaser class to synchronize 3 concurrent tasks. These 3 tasks will search for files with a. log extension in 3 different folders and their subfolders. This task is divided into
Phaser Drag LineWhy drag the line, it feels like pulling ramen. But this effect is currently a small game application needs, is the child game link to find the answer.
How to AchieveA line in the Phaser world is a combination of rectangles, which is a straight line by making these rectangles fill the same color. Of course, we can use a circle to combine, so you need to accept the low efficiency of the circ

First, I declare that my ideas may not be correct, because I am also an unsuccessful person, just a reference value.
Today, our company is interviewing developers who are not engaged in software development. They are also engaged in e-commerce in
The English version of Windows Vista RTM that has been circulating in this network cannot be installed on a hard disk. However, I am suffering from no such person as a DVD recorder. Finally, on the vision forum, we can see that someone has
Put it in front: although it is now a USB simulator, but there are still some compatriots using the serial port Weifu simulator, so write down the following process. Hope to help.
I don't need to talk about installing software.
Step 1:
The idea is to first the largest plus the smallest, first wash out to find a dry biggest, after washing out to find a brush dry the smallest, so the theory is the smallest time
Say the practice, is two queues, constantly go to update, first go to
' M thread-1,i ' ll go ...}3. Exchanger of Synchronizerthe Chinese translation of the Exchanger class is: exchanger. Perhaps the most interesting Synchronizer is exchanger, which is designed to simplify the exchange of data between two threads. The operation of the Exchanger object is simple: simply wait until two separate threads have called the exchanger method, and the data is exchanged at this time. The constructor is: exchangerThe Interchange method is: v Exchanger (v Object) v Exchanger (
Controlling the change of concurrent periodic tasks
The Phaser class provides a way to execute each phaser change phase. It is the Onadvance () method. It receives 2 parameters: the current number of stages and the number of registered participants; it returns a Boolean value, False if Phaser continues its execution, otherwise true, that is,

language provides a synchronization helper class that allows multiple threads to wait at a collection point
Phaser: It runs concurrent tasks in multiple stages, and all threads in the current phase must perform before the next phase begins.
Exchanger: It provides a data exchange point between two threads.
In the application, semaphore can be used at any time to protect the critical section because it is a basic synchronization mechanism.
