I have introduced some examples of Python and C ++ interoperability. Series of articles: Python calls C/C ++ functions (1) Python calls C ++ (2) encapsulated by boost Python) C ++ calls Python (3) C ++ calls Python (4) C ++ and Python advanced application interoperability (5) C ++ calls the pythonapi thread status and global interpretation lock (6) It is very prone to problems, such as Unicode problems and importerror problems. So let's introduce the installation and configuration. 1. Install P

Using shell commands under Linux often uses shell output redirection like this: 1>/dev/null 2>1 At the end of the shell command, we can redirect the output through the > symbol. 1. Standard input stdin file descriptor is 0, standard output stdout file descriptor is 1, standard error stderr file descriptor is 2 2./dev/null empty equipment files, equivalent to garbage cans 3. REDIRECT Symbol:> Explain

I summarized the error before creating an ASM Disk: http://blog.csdn.net/rhys_oracle/article/details/17029333 This is the case today. As follows: When you use openfiler to map to a local disk through iSCSI, the following error occurs when you create the entire disk as ASM: [[emailprotected] iscsi]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdhMarking disk "VOL1" as an ASM disk: [FAILED][[emailprotected] iscsi]# tail -5 /var/log/oracleasm Cleanin

In my recent project, I need to use JNI to call C/C ++ compiled programs. Since I was not familiar with JNI, I found many of them on the Internet are implemented based on the VC or vs2008 series. In this way, it is very troublesome to install hundreds of megabytes of VC or several GB of vs for a simple call, because I have been using Dev C ++ for C Development (this Dev is very compact and powerful, but it

/dev/null fileIf you want to execute a command, but you do not want the output to appear on the screen, you can redirect the output to/dev/null:>/dev/null /dev/null is a special file, and the content written to it is discarded, and if you try to read from the file, nothing is read. However, the/

A few days ago, the hands of the cheap, accidentally deleted/usr. So carved a BACKTRACK3 boot disk, go into the system backup.I mounted the home with mount/dev/sda6/mnt/home and then tar cf/mnt/usb0/bak.tar/mnt/home back up.After the backup, I backtrack3 in the virtual directory around, suddenly, I found/media directory also has a home folder, open a look, found and/mnt/home exactly the same!Originally, the/MNT directory holds the hardware that is mou

The shell may often see: >/dev/null 2>1 Eg:sudo kill-9 ' ps-elf |grep-v grep|grep $1|awk ' {print $} ' 1>/dev/null 2>/dev/null The result of the command can be defined as the output in the form of%> /dev/null represents empty device files > represents where to redirect, for example: echo "123" >/home/123.txt1 indic
