SAMBA service construction and samba Construction1. Introduction 1. Understanding Samba is a set of applications that use the SMB (Server Message Block) protocol. By supporting this protocol, Samba allows communication between Linux servers and Windows systems, make cross-platform mutual access possible. Samba adopts the C/S mode. The working mechanism is to run NetBIOS (the communication protocol of Windows Network neighbors) and SMB on the TCP/IP co

Source: http://www.blogjava.net/flustar/archive/2007/12/03/builder.htmlBuilder mode definition: separates the construction of a complex object from its representation, so that different representations can be created during the same construction process. When I first came into contact with this model, I really couldn't understand what it meant and what's the use of it. As a result, the Internet Googled and

I. aforementioned Azkaban is a workflow scheduling tool. Because of the dependency between tasks, traditional crontab tasks cannot meet the requirements. Therefore, you need to create a workflow engine. Compared with ooize, Azkaban provides task submission as a client. Ooize randomly distributes tasks to our cluster environment. Considering the common architecture, we chose Azkaban for workflow engine. However, there will always be various problems in building tutorials on the Internet, which is

First, the construction methodThe constructor method in OC is the method at the beginning of Init, which initializes an object so that an object is created with some properties and values.The constructor method belongs to the object method, starting with "-"For example, the Init method is called when the object is created.Person *p = [[Person alloc] init];can be decomposed intoPerson *P1 = [Person alloc]; Allocate spacePerson *p = [P1 init]; Initializ

Java memory structure, class initialization, and object construction process, java Construction There are already many articles on this topic on the Internet.
