Good programming principles are closely linked to good system design principles and technical implementation principles. The following programming principles have made me a good programmer in the past years, and I believe that these principles can greatly improve the programming capabilities of any developer, allowing him to develop programs that are more maintainable and less flawed.　　I don't want to repeat myself -this is probably one of the most basic tenets of programming development, which

0. Write in frontFor the first contact with the Linux system, the installation of ns-3 seems unfriendly. But in fact, the installation process is not as complicated as it seems to be in a methodical way. In this paper, the installation process in the official Wiki is slightly combed, hoping to bring some convenience for beginners. As the description in the official Wiki is sufficiently detailed, there will

Now many friends have their own blog page, although they may not want to go to the wood to write a personal diary of the way, but to highlight the personality, publicity of the purpose of the ego, mostly similar. In fact, at this time, many of China's technology fans have looked to the wiki. After the network anti-Huang and Miko Mi, China's netizens have been familiar with the blog. As a new network concept, with the support of sophisticated technolog

Previously, moinmoin1_topedition was installed in Windows XP as its local Wiki (using MoinMoin desktop edition as a personal local knowledge accumulation tool). Because Ubuntu and Winxp systems are used, it is hoped that the two systems share the same wiki program without data synchronization, which will cause trouble for Data Query and save the maintenance of data synchronization. MoinMoin does not require

Don ' t Repeat yourself (DRY)DRY is one of the simplest laws and is the easiest to understand. But it can also be the hardest to apply (because to do so, we need to do a lot of work on generic design, which is not an easy task). It means that when we find some similar code in two or more places, we need to abstract their generality into a unique new method, and change the existing code so that they can invoke the new method with some appropriate parameters.Reference : http://en.wikipedia.org/

Original article: team collaboration with GitHub GitHub has become the cornerstone of all open source software. Developers like it, collaborate based on it, and constantly develop amazing projects through it. Except ?? Code hosting, GitHub's main attraction is to use it as a collaborative development tool. In this tutorial, let's take a look at some of the most useful GitHub functions, especially those that make the team work more efficient, more productive, and very important and fun! GitHub a

A good programmer generally consists of four aspects: Operation Skills, Knowledge Level, experience layer and ability. I would like to share with you some of the principles in design. I think these things are lessons learned from long-term experience. Every programmer should understand these principles. However, we recommend that you do not adopt dogmatism. You must consider the actual situation when using it. In fact,The following principles can not only be applied to software development, but

Before installation, you can count the number of existing instances. If there are no ready-made devices or devices to be moved, a little foresight is required during installation. Consider the channels, switches, routers, servers, PBX or ip pbx systems, and any storage ne

calls. Then, you also need to assess whether the available bandwidth will support the demand in the plan, or whether you need more bandwidth. In this regard, the financial reality is an inevitable factor, because your budget may not support your need for bandwidth everywhere. Therefore, you must control the number of users that can access this bandwidth at the same time. In addition, when there is no bandwidth for a phone call, you will receive the same feedback as the public exchange phone cal

difficult thing is how the learning system works," he said. Once the staff have a full understanding of the Unified Communication structure and user needs, the rest of the work is to discover and solve possible problems at work ." However, it takes time to acquire the necessary knowledge, he adds, "the process of discovering a problem may last for weeks. Perfection is not easy. If enterprises want to avoid the collapse of the communication system, such long-term efforts are necessary ." Jim o'b

User subsystem: A User subsystem consists of a connection between a terminal device and an information outlet. It consists of a connector and an adapter. Horizontal subsystem: connects the information outlet and Management Subsystem wire jumper. This type of connection is usually achieved by five or more 8-Core 4-pair twisted pair wires. Management Subsystem: The management subsystem is composed of a connecting and connecting distribution frame. The management point provides a means to connect

: 　 VoIP gateways are mainly used for IP telephone communication between enterprise branches. They can provide traditional voice interfaces and connect to existing enterprise telephone switches (PBX) or group telephones, and bypass the long-distance phone to the IP network Internet/Intranet ). The main feature of VoIP Gateway applications is to make full use of existing network resources, save users' long-distance calls, and combine with the existi

-VP504 FXS through the AT-VP504 FXO over the IP network to maintain original compatibility. Using the "Hop-on" and "Hop-off" PSTN gateways, you can enable the PSTN phone to enter the company's IP network from the local device, send it to all over the world through the IP network, and then access it through another destination PSTN gateway.Solution Analysis1. Application of dedicated small switch Extension In the example shown in figure 1, the connectivity of the central

Q: How does an organization support IP phones and other devices on its network? Does this support cause complicated additional connection lines and electronic problems? Hyde: Ethernet power supply is an increasing area. As more enterprises transition to VoIP, reliability has become a problem that must be solved. Network administrators preparing to upg

Many of them are plug-ins used by the vendor's network data analyzer to analyze VoIP. Test Method Connect the VoIP analysis tool to four ip pbx systems. They are: EADS telecommunications Nexspan L systems using private protocols, Mitel SX-200 ICP, both using private protocols and

bandwidth for a phone call, you will receive the same feedback as the public exchange phone call. It should be noted that, this feedback can be seen as a "busy" signal of VoIP. IP-PBX has this built-in feature. They know the network structure, and they also have parameters that determine the number of simultaneous voice calls allowed between sites. When the network reaches this limit, the IP-PBX may send a
