The iputils package contains ping, a basic networking tool. The ping command sends a series of ICMP protocol ECHO_REQUEST packets to as pecified network host and can tell you if that machine is alive and receiving network traffic.ipv6calc is a small utility which formats and calculates IPv6 addresses in different ways. It extends the existing address detection on IPv6 initscript setup or make life easier in adding reverse IPv6 zones to DNSor using in DNS queries like nslookup -q=ANY ipv6calc -r 3ffe:400:100:f101::1/48`

Java For Artists targets both the undergraduate computer science or information technology student and the practicing programmer. It is both an introductory-level textbook and trade book.
As a textbook it employs learning objectives, skill-building exercises, suggested projects, and self-test questions to reinforce the learning experience. The projects offered range from the easy to the extremely challenging. It covers all the topics you’d expect to find in an introductory Java programming textbook and then some.
As a trade book it goes purposefully deeper into topics cut short or avoided completely in most introductory textbooks. Its coverage of advanced GUI programming techniques, network programming and object-oriented theory will enable you to take your skills to a higher level.
MATLAB的SVM算法實現(xiàn)，Matlab Support Vector Machine Toolbox，This toolbox was designed as a teaching aid, which matlab is
particularly good for since source code is relatively legible and
simple to modify. However, it is still reasonably fast if used
with the supplied optimiser. However, if you really want to speed
things up you should consider compiling the matrix composition
routine for H into a mex function. Then again if you really want
to speed things up you probably shouldn t be using matlab
anyway... Get hold of a dedicated C program once you understand
the algorithm.
ARP test mode. According to the idea we design the arithmetic for the key part, first the system sends a message to the target machine, and then system wait for the response. Once system receives a message, it starts to analyze the message, according to the message s parameter system judges whether the message satisfies the conditions. Once the message satisfies all the conditions, the system thinks the machine is sniffing, and adds this machine into the list of sniffing machines. On this basis the detection has done well, and at the same time we insert the result into the log database for inquire and analyze later.
At can be given its arguments in a file. You can comment
out lines by preceding them with either # or -
characters. This is an easy way to temporarily disable
some commands.
The CONTINUE-command is most useful at the end of the
file. When this command is read, the file is started
again from the beginning. You can use it situations where
the machine is not shut down for the night and you want
to run some commands every day.
是否懂得C語言并不是學(xué)習(xí)C++的前提。不僅僅是因為C++本身兼容C語言，更重要的是C++所倡導(dǎo)的程序設(shè)計觀念是和C語言完全不同的。C語言在某種意義上是對CPU模型的抽象。盡管C++完全保留了C語言的機(jī)器模型，但是C++更加注重對現(xiàn)實世界進(jìn)行抽象。為此，C++創(chuàng)始人Bjarne Stroustrup專門寫過一篇著名的文章：《Learning Standard C++ as a New Language》（把標(biāo)準(zhǔn)C++作為一種全新的語言來學(xué)習(xí)）
BPMLL is a package for training multi-label BP neural networks. The package includes the MATLAB code of the algorithm BP-MLL, which is designed to deal with multi-label learning. It is in particular useful when a real-world object is associated with multiple labels simultaneously
If you are using Internet Explorer on Windows XP Service Pack 2, there is a security restriction disallowing scripts to run in files opened on your local machine. When you first try to run the examples, you will most likely get a message saying, "To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer." To see the example, you must click on the message and select "Allow Blocked Content".
