Run a program A on the Xshell terminal today, then close the Xshell terminal and then go to Xshell with Ps-ef | The grep process name found that process a has been hung. Later on the Internet to find some information, cause the shell to open a process, when the shell terminal is closed, it will be opened to all the terminal process to initiate a hangup signal, all the process of signal processing exit, if we want to continue to run the process when exiting the shell, You need to use Nohup to ign

Standard query operator and standard query operator The emergence of Linq makes the code much simpler. It was basically used in the project before, but it has not been fully organized. Today, we will use it this weekend to facilitate later use of it. Linq operations can be divided into aggregation, join, conversion, element operators, equal operations, generation, grouping, division, projection, quantity, f

Part 1ArticleStl_deque's design philosophy and STL memory management are explained in a rough way. At least we can see the tip of the iceberg. In this article, I will refine the analysis of vector and analyze some functions in detail. In some cases, it is better to clarify some problems. Open the source code of stl_vector and find that the design idea of the vector is exactly the same as that of stl_deque. It is reasonable to think about it and maintain the consistency of implementatio

Operating systems typically have three standard file descriptors: standard input, standard output, standard errorThis is an abstract expression of the operating systemDifferent languages need to have different specific expressions, and of course it's just another packaging abstraction.For example, C + + cin cout CerrIn

The standard input is the file descriptor 0. It is the input to the command, the default is the keyboard, or it can be the output of a file or other command.The standard output is the file descriptor 1. It is the output of the command, the default is the screen, or it can be a file.The standard error is file descriptor 2. This is the output of the command error,

Sample variance and sample standard deviation 1. Definition: The average of the difference between the data in the sample and the average of the sample is called the sample variance, and the arithmetic square root of the sample variance is called the sample standard deviation. Note: Both the sample variance and the sample standard deviation measure the amount o
