As the preferred server-side data processing technology, Java Servlet is rapidly replacing CGI scripts. One of the advantages of servlet over CGI is that not only can multiple requests share public resources, but also can retain continuous data between different user requests. This article introduces a practical technology that gives full play to this feature, that is, the database connection pool. I. Significance of implementing the connection pool Dynamic Web sites often use the informat

In the last few sections we have configured the SharePoint three-tier farm installation. In this section, we will simply verify the load and search capabilities under balance.A balanced load of hardware can generally be used in a production environment, or NLB in Windows itself. The method of DNS polling is used to verify the load balance.1. DNS resolutionThis adds a XCLOUD.PW DNS zone, PORTAL.XCLOUD.PW this URL as the homepage of the site.Add 2 A rec

The supercell is organized into a rectangular array of column C in the r row, Rc = D. The address of each supercell is expressed by (I, j) (starting from scratch ).

1. Reading The Recurrent neural Network (NN) is the most commonly used neural network structure in NLP (Natural language Processing), and the convolution neural network is similar in the field of image recognition. Before we introduced CNN in detail in 4 blog posts, it is now necessary to introduce RNN before using CNN for a variety of purposes. Then it will be better to integrate practice.
