At first, I had to manually create several modules when writing the application. Recently I found a good thing Basho-rebar. Using rebar to create an application can automatically generate three files: Lqg_app.erl Lqg_sup.erl LQG. App. SRC Then, add the personal logic business, and an application will soon be released ...... Specific practice: ====== here Basho-Lager (Erlang's log application) is used as an

Create and configure an instance for the NFS development environment of Embedded linux-general Linux technology-Linux programming and kernel information. For details, refer to the following section. In the application development stage, the NFS method is more efficient than the ftp method, because it does not need to download the linux server program to the Embedded Target System for debugging. Next we will

In fact, struts2 is not an upgraded version of struts 1, but an upgraded version of webwork. Because struts2 is a webwork upgrade, rather than a new framework, it guarantees stability and performance in all aspects: it also absorbs the advantages of struts 1 and webwork, it is a good framework, which is very simple, clean, and powerful. Next we will use struts2 to create a simple logon instance. After decom

functions. Gsoap contains two tools, wsdl2h and soapcpp2, to generate a code framework. To develop a web service program, you need to use gsoap to generate the server and client code framework (generally, you need to implement the server or client, because the other end is usually prepared by others, for example, the onvif in ipnc is implemented on the server side ). We have two methods: Write the WSDL, use wsdl2h to generate the header file, and then soapcpp2 to generate the Framework Code;Com

The first contact with the Nodejs file system was confused by its asynchronous response, and later found that Nodejs to determine whether the folder exists and create a folder is still synchronized method, but still want to try to use the asynchronous method to implement. Methods to use: Fs.exists(path, callback); Fs.mkdir(path, [mode], callback); The creation code that implements the folder directory structure is implemented as follows:

A database trigger is a storage subroutine associated with a data table, view, or event in a database. For example, we can enable the Oracle database to automatically activate a trigger before or after an INSERT, UPDATE, or DELETE expression affects a table. One of the functions of a trigger is to review data changes. For example, the following table-level Trigger is activated after the salaries field of the emp table is updated.Create trigger audit_salAfter update of salON empFOR EACH ROWBEGINI

accessible by PHP, so you need to confirm that the file access permission allows that access. If Safe mode is activated or open_basedir is applied, further restrictions apply. If PHP believes that filename specifies a signed protocol, and that the protocol is registered as a network url,php will check and confirm that Allow_url_fopen has been activated. If it is off, PHP will issue a warning, and fopen's call fails. 2. Mode specifies the open mode with the following possible values: PHP fopen
