In the previous article on the LIBSVM process and the simple Java code test to explain, this article is simple to libsvm how to practice in the project short description, inappropriate places welcome you to correct.The first step is to adjust the predictive function of LIBSVM, and I'm taking some of the code from the Svm_predict class to make predictive defenses,

After the use of Zabbix for monitoring, often because of the requirements of the project, the need for Zabbix data, two times to share and develop. How to obtain data from Zabbix is a problem to be solved in this practice. There are two ways to Zabbix data sharing 1 through the database query, get the data. The premise is to have a deep understanding of the Zabbbix database model, and in a large number of monitoring, can not because the query affect t

Reflection calls Private method Practices (PHP, Java), There is a universal problem in the single measurement, which cannot be called directly by the private method in the side class. Small drag in the process through reflection to change the method permissions, the single test, share, directly on the code. Simple Test class Generate a simple tested class with o

Java Theory and Practice: Concurrent collection Classes util.concurrent In addition to many other useful concurrent building blocks, the Douglea package contains some of the major collection types List and Map high-performance, thread-safe implementations. In this month's Java theory and Practice ,

on the Java Practice report, overall is not difficult, for me the biggest difficulty lies in the use of the collection, which also shows my seventh chapter and even the overall use of Java is not good, the seventh chapter because of the lack of proficiency because the code volume does not knock much, many things do not understand, The use of double-row sets and s

a callback function (Onnativecallback) that is called by the JNI layer and prints the value of count in the callback function.Looking at how the JNI layer opens threads and calls back to the Java layer (NATIVE.C), the key points are commented in the code:Native C implementation:1. header file inclusion and definition of global variables2. Implementation of the initialization function3. Turn on the shutdown thread implementation4. Threading implementa
