A session is literally a conversation. How can we understand it in our system? A session is an interaction.ProgramThe interaction between the client and the server is a session. The session survival and the client and the server are widely used in the software industry. sessions are very familiar to the Web, A session represents an interaction between a web serve

Recently, a B/S application software was just completed, which was written in vs2003 using VB. NET. A simple software registration function is added to the software at the customer's requirement. The main principle is to first obtain the machine cpu id, then add the unit name into a string, and then encrypt the string with MD5 to obtain the registration code. The

The Universal Device Interconnect Framework (CDIF) is a Web-based connectivity framework, and some open source implementations are currently housed in the Github-out4b/cdif:common device Interconnect framework. CDIF is a JSON-based SOA software framework. CDIF provides the client app with the same abstraction capabilit

naturally produce two classes for teachers and students, but everyone will think that" people "should be extracted as the base class (parent class) for teachers and students ). However, we know that a person does not exist in this semantics. He just assumes it based on experience. As we have said before, classes are the abstraction of objects (real things), while parent classes are the re-Abstraction process of classes. Therefore, I think:Inheritance

Operating System An embedded operating system is an operating system software that supports embedded system applications. It is a dedicated operating system with outstanding features in real-time, hardware relevance, and software solid-state. The system uses an embedded Linux operating system, which is based on the system requirements for the Linux operating s

Web server is the application layer protocol, and currently, we mainly follow the protocol as http/1.1. The HTTP protocol is the foundation of web development, a stateless protocol that completes a session between the client and the server through the request and corresponding. In each session, the data sent by both parties is called a message, and there are two types of messages: a request message and a r

cite an extreme example. If we have a Cassandra cluster and it's made up of five physical machines. One of the physical machines is 4 times times the capacity of the other physical machines. Then setting the replication factor to 3 o'clock will cause the same data to be stored on a physical machine with a larger capacity. It's not much better than setting it to 2. So in determining the replication factor of a Cassandra cluster, we carefully set an appropriate value

stored items. The algorithm is dynamically determined based on some factors. For example, the first algorithm is used on Monday. Today is Tuesday. Another algorithm is used. All in all. Do not naively think that it is safe to store the password with MD5 in the database. Do not write such simple things unless you are a student. In my summary. Confusing, dynamic, encrypted, and encrypted multiple times, stor

2005 finally passed. In retrospect, it was quite rewarding. I lived in a narrow space. With the passing of 2005, I began to break through a "circle" and began to think about www. When I looked at the Internet again, I found myself falling behind, therefore, we began to plan what we should do in the Web 2.0 era. Actually, I am not a professional developer, so I cannot tell what the technology is. Sometimes I wonder, after this century, is there a very

every department, it leads to a large number of useful but isolated and repetitive business logic blocks. If the design and development can avoid duplication of design, but the use of software sharing methods to achieve the same function of each module, it will greatly reduce the cost of software development, but also for the future system upgrades and integration to provide a good framework for the founda

Agileeas. as a fast application development platform, the net platform aims to improve the production efficiency of application software. There are many methods to improve the production efficiency of software development; it can be an effective way to use work to simplify low-and mid-level technical repetitive work in development. On the agileeas. NET platform, we provide a set

Introduction Phpeasyvcs is a simple version control system (VCS) and WebDAV server with minimal hosting requirements: PHP 5.2+ No database is needed. Files can be viewed and uploaded with a browser or by WebDAV. License:gplv3 If you want to see the web interface of Phpeasyvcs, either See the screenshots or Go to the demo site (login with username demo and password demo). Upload files up

interaction is very complex, function reuse is low, cannot be applied to web or other application environments. For this reason, I have referenced some functions of cab and scsf and designed a commom UI Platform specification in 2007 to design a more powerful and simple modular rapid development platform. However, in 2008, I had more ideas and proposed a uishell product concept. Uishell is the abbreviation of the English user interface shell ". It i

2000 will be reduced, but at least some features (such as good replication and server status monitoring) can be used. In the test, only normal network load balancing is investigated, and external factors are not taken into account. Simple operationBasic server group management operations are relatively simple. Application Center 2000 uses the familiar operation interface of the Microsoft Management Console (MMC. The manager can run the software insta

The stepper motor drivers seen on the web are all the same for array storage IO status table output with fewer subdivisions. First to comb what has now been done, there is an array of memory in the entire sine half-cycle of the real-time operation of the SPWM data, this data is based on the current PWM period is converted, Therefore, each PWM cycle sequentially assigns the array contents to the timer chann

centralize management and maintenance, the client is actually just a terminal function, from a certain point of view is the extension of the host screen. With the development of distributed concept and the enhancement of computer function, the software industry has put forward the client/server computing model, put some non-critical tasks (such as graphical interface display, data display format determination, data processing, etc.) to the client to
