lightweight m2m

Abstract: M2M is short for machine-to-machine/man. It is a networked application and service centered on intelligent interaction of machine terminals. It embeds a wireless communication module in the machine and uses wireless communication as the access means to provide customers with comprehensive information solutions, to meet the customer's information needs in monitoring, command scheduling, data collection and measurement.

As you know, the multithreading security of Java is implemented based on the lock mechanism, and the performance of lock is often unsatisfactory.The reason is that Monitorenter and Monitorexit, the two bytecode primitives that control multithreading synchronization, are implemented by the JVM relying on operating system mutexes (mutexes).A mutex is a resource-intensive operation that causes a thread to hang and, in a short time, needs to be re-dispatched back to the original thread.In order to o

In the process of planning and designing a website or software, we often hear this discussion: "This function is designed too much" or "we want to be able to handle it more lightly". It seems that light design is a hot topic today, but also in the ascendant Web2.0 of the designer's favorite (see Those in the world everywhere SNS site, whether visual elements or interactive process can be light light). This paper, from the point of view of practice and summarization, puts forward 6 techniques to

A simple database access layer based on EntityFramework Core, applicable to lightweight database services and lightweight Databases The code of this access layer is actually from a senior in the garden. I just thought it was good and recorded it. The access layer needs to install EntityFramework Core through Nuget, but I personally think EF 6 can also be used. It is best to match databases with SQL Server (

string by "/" and into the array $getparam. The reason behind the for loop is starting from 2 is because $getparam[0] represents the controller, $GETParam [1] represents the method. These are not parameters, they are all in the $_get, and they are some parameter information. The following controller name and method name is the first detection of the existence of $getparam, if it exists in the $getparam, if it does not exist then the detection according to the controller nam

first, micro-services will become lightweight Architecture needs to be designed by people, who are called architects. Many people may not have given the architect the title, but they are doing the work of architecture. We believe that the structure of this work will always need to be done by people, may not be in the short term by the machine to replace. If we do not understand what the architecture is, or if we are puzzled by the responsibilities of

A mechanism for fast data access is urgently needed. At the micro lev

First, the weight of class lockIn the previous article, we introduced the usage of synchronized and the principle of its realization. Now we should know that synchronized is implemented by a monitor lock inside the object. But the nature of the monitor lock is implemented by the mutex lock which relies on the underlying operating system. and the operating system to implement the switch between the threads that need to transition from the user state to the nuclear mentality, the cost is very high
