Dumps (): convert the data in the matrix to a string.
Fill (value): fill all elements in the matrix with the specified value.
Flatten ([order]): converts a matrix into a one-dimensional form, but it is still a matrix object.
GetA (): Returns itself, but is returned as an ndarray.
GetA1 (): returns a flat (one-dimensional) array (ndarray)
GetH (): returns the transpose matrix of its own bounded complex numbers.
GetI (): returns the inverse matrix of itself.
GetT (): returns its transp

do packet filtering, then the BPF code can only be used to do packet filtering? Not also. The kernel's BPF support is an infrastructure. is just a way of expressing the middle code. is to provide a public interface to the user space that injects the running code into the kernel. It's just that most of the applications now use this interface to do packet filtering. Other such as Seccomp BPF can be used to restrict the user process can use the system calls, CLS_BPF can be used to classify traffic

Most people use grep to find the specified process in the PS aux output when they write the shell filtering process, but they also display the grep process, such as finding the pptpd process, which matches two:

2. Use of existing communication middleware 2.1 ActiveMQ Transfer File interface
In order to solve the problem of transferring large files, ACTIVEMQ introduced the concept of JMS streams outside the JMS specification. In PTP mode, connected to both ends of the same destination, you can transfer large files via broker relay.
The sender uses Connection.createoutputstream to open an output stream and write files to t
available for each message.
Kimmking: We call this pattern point to point, PTP.
Sen: Why only one message can get to each message.
Kimmking: Just one piece of data cannot be repeated to two consumers.
Kimmking: For example I have an apple, you three people want, I can only give one person. One more apple, I can only give one person.
Kimmking: This man may not be the same person as the one in front of him.
Everyone: Take it and it's gone. Equivalent t

People can use anonymous FTP when they know the host address of specific information resources, but anonymous F
