The interface segregation principle is Robert C. Martin (!) The fourth article (original) of engineering notebook, a column written in C ++ reporter in 1996, describes how to deal with the troubles caused by interface "bloated. This principle has only one sentence in summary: clients shocould not be forced to depend upon methods that they do not use. Customers should not be forced to rely on methods they do not need. The popular ISP statement is gene

I don't know where you are. Anyway, I have a place called the ISP bandwidth service provider, Dr. Peng ... As the original credulous landlord said the legendary telecommunications plus the Great Wall Broadband dual service, the last to pull the landlord's net. As a result, I have never encountered my own IP address is telecommunications. Dr. Peng has always been the bar called the Great Wall broadband. I'm going to go oh ~ ~Always hijack my DNS, and,

Who will deploy dual ISP in IPRoute2 on CentOS? -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Our company has two links, one of which is ADSL and the other is fiber optic 2 m; I cannot deploy duisp in IPRoute2 on CentOS. Who has shared this example? I have two ideas: 1. If I want to use an inboud bandwidth of 2 MB, I will transfer the traffic to ADSL. If the link of 2 m is less

TVs, It is necessary to improve the received image resolution to match the physical resolution of the LCD screen, in order to display the video image on the terminal, therefore, the quality of the Scaler performance will directly determine the display image.Image scaling can be understood as the resampling process of image, the key is to use continuous model function to fit the original discrete image, after the continuous model parameters are obtained, the continuous image is resampled accordi

ISP (interface segregation principle), interface isolation principleThe requirements are as follows:① The dependence of one class on another class should be established on the minimum interface.② It is better to use multiple special interfaces than to use a single total interface.③ Unrelated interfaces cannot be merged into a bloated large interface.④ A bloated large interface should be divided into several suitable small interfaces.Interface separati

Here are a few ways to connect you beyond your ISP and make it easy to connect to your database: 1.SQL Server CStr = "PROVIDER=SQLOLEDB; Server=CStr = CStr "network=dbmssocn;uid=Set conn = Server.CreateObject ("Adodb.connection") Conn.Open CStr ' Connect with NETWORK=DBMSSOCN to avoid errors caused by admin naming

this: when the machine is started, will u8expstep = 255, s16exptolerance = 50, this is because the image appears faster, if the setting is small, the image will be from dark to light about 5 seconds (here to see personal needs). When the machine executes to about 5 seconds, we then set the value to U8expstep = 16, S16exptolerance =10,u8expstep is set to 16 because preventing changes in the light source will cause the image to quickly effect (flash flash). The s16exptolerance set to 10 is set fo
