software routers. In addition, software routers generally have higher hardware configurations than hardware broadband routers, in some cases, the speed is faster than the stability of the hardware router with tens of thousands of yuan. The stability of the software router has benefited from the stable Linux and BSD kernels. The stability of the

In the past, I wrote a monitoring script to check the IP addresses in an IP list every 10 seconds by using the ping command. If the IP addresses in an IP list cannot be accessed, send messages via the messenger message and use beep to send alarms. Run the script.Rem main. bat @ Echo off For/F "EOL =; tokens = 1, 2 * delims =" % I in (IP. txt) Do call: checkip % I % j 0 Echo ---------------------------------

A year ago, Stanford and Apple jointly launched a development course based on the iPhone platform. The PPT of this course was shared online, and the response was very good. This semester, Stanford recorded the course and put it on iTunes University for download. Currently, this course ranks first in iTunes downloads, reaching 1 million downloads. This is a lecture on "10 steps for successful iphone software

A detailed description of the top command:1. Top: Dynamic monitoring process.First line: Current system time: Up 4days: Duration after server startup. 5 User number of users on the current server; Load average: The average of three is less than 0.6.The second line: the current number of processes in the system, the number of sleeping processes, the number of running processes, the number of stopped processes, and the number of 0 zombie zombie processe

In the embedded software development process, generally, the time spent on testing and coding is (in fact, more ). This ratio keeps decreasing as your programming and testing level increases, but software testing is very important to the average person. Many years ago, a developer asked Oracle the following question in order to have a deeper understanding of embedded systems: How can I know what my system i

engineer will focus on three basic types of reuse: first, the reuse of internal infrastructure, corresponding code written by himself or colleagues; second, using third-party function libraries, such as JDK. Finally, we will study the use of services provided by some large network service providers, such as Amazon. In short, correct use of existing code enables software engineers to focus on the most impor

the mobile user environment. Through the cooperation ISP or its own ISP users, you can directly access the network through the VPN, therefore, there must be strict standards for user orientation and access methods. 7. Operating System: Use a standard and stick to it. configure a strong win2000, disable personal WEB Services and other unnecessary services, and fill in all the necessary supplements. 8. User-managed security: users cannot manage their o

Many things cannot be clearly expressed, and charts are more intuitive. For example, if you are looking for some of my design project friends, they usually do not use any professional terms to describe their own needs, and it is hard for me to understand what they really want. A simple graph is clear to everyone. It is usually okay to use word for simple needs. However, word is far from enough to make professional flowcharts and other charts, at least not convenient.

So I think, to grasp the domestic
