In Android, data transmission between images is mainly implemented through the putextra method of intent. The transmitted data structure is a map data (name/value pair, note that the difference is that the basic data type must be used. The following describes the implementation methods through instances. This example d

In the previous article, we learned more about SDS's work and operation process through SSDs Explorer. In this article, we will explain in detail how to use the programmer's method to manipulate SDS. SDS provides SOAP and rest two kinds of interfaces, here we use rest+c# method to explain. Soap is the same as it is, please check MSDN with your interested classmates. Less gossip, let's take the example of creating authority, giving the "universal framework" of Rest-operation SDS: public strin

Intro Recently looking at machine learning related video tutorials, which talked about the clustering algorithm through Kmeans, the idea of studying the algorithm and showing it step-by-step through Python is the whole process of the algorithm. principle The specific principle of kmeans found that a tutorial in the evening showed a clearer picture of Kmeans, as follows: Http://www.csdn.net/article/2012-07-
