Linux Multi-command collaboration: Pipelines and redirects don't reinvent the wheel. One of the core concepts of open source culture is not to reinvent the wheel, many of the open source software is a re-assembly of existing software, code, functions, as if through parts assembling machines, the development and sharing of source code makes this possible, At the same time, it also greatly provides efficiency and productivity.Pipeline and redirection in
In the previous article we talked about using wait () and notify () to collaborate between threads, which is straightforward and flexible, but before using the lock of the object, the number of notify () calls that are less than the number of waiting threads can cause threads to wait. The advantage of indirect collaboration is that it is simpler to use and less error-prone, as we talk about the way in which multithreading works indirectly, blocking qu
Design of communication and collaboration, this topic one throws, let me very big.
A lot of bad stuff between demand side, product manager, UIUE, program, test. It involves a third party, or even a few companies, rather than a company, and the difficulty of communication is compounded. And if it comes to collaboration with the Government, it's a disaster, 2012.
Even if internal communication, taking into

Net, which is a new concept introduced by Ms during VS2013, and there's a lot of information about it on the Internet, and here I'll talk about my own understanding:
OWIN is a norm and a standard, does not represent a specific technology . Some of the newest new technologies, such as Kanata, Identit
The no-Wait multi-thread collaboration mechanism proposed in "multi-thread collaboration under real-time rendering" can be applied to real-time rendering. This is because there is a correlation between each frame and the next frame in real-time rendering. Imagine that there is an infinite and Fast Rendering device, resulting in an infinite frame rate and an infinitely small dt. In this case, the motion chan

Thread collaboration is required to write multithreaded programs. The previous introduction of the use of mutual exclusion to prevent thread racing is to solve the derivative harm of thread collaboration. The key to writing a thread collaborator is to solve the problem of coordination between threads, in which some of these tasks can run in parallel, but some steps require that all tasks be completed.wait (

When you call sleep () and yield (), the lock is not released, and the Call to wait () releases the lock. This way another task (thread) can get a lock on the current object and enter its synchronized method. Execution can be resumed from Wait () by notify ()/notifyall (), or time expires. Wait (), notify (), and Notifyall () can only be called in a synchronous control method or in a synchronization block. If these methods are called in a non-synchronous method, the Illegalmonitorstateexception
Thread collaboration Methods: sleep, yield, wait, join, and sleepyieldSleep)
When the t Thread calls Thread. sleep (), the Thread t will sleep for a specified time.
Thread. sleep () and Thread. currentThread (). sleep () have the same effect.
The sleep method does not release the synchronization lock.
Sleep does not affect other threads.
Yield (concession)
When Thread. yield () is called in the t Thread, the t Thread will

JAVA thread collaboration: Condition
The built-in condition queue has some defects. Each built-in lock can only have one associated condition queue. Therefore, in the BounderBuffer type, multiple threads may wait for different condition predicates on the same condition queue, in addition, the condition queue object is exposed in the most common locking mode. These factors make it impossible to meet the requirement that all the waiting threads are of a

Define the total production cap max_produce and the maximum capacity per producer (upper limit) max_signle_produce and the maximum amount of consumption per consumer max_single_consume, in particular: if the total production after a single production is not up to the limit , the locks produced by producers at this time may be a

That is, the number of pits.The transparent transparent (private), to the external exposure must only expose the need for no points. Avoid so
