Linux Tour (1): diff, patch and quilt (lower) 2 quilt
We can use CVs or SVN to manage all code for our own projects. But sometimes we need to use projects maintained by other developers. We need to modify some files, but we cannot directly submit code to the version management tool. It is not appropriate to use version management tools to reconstruct the entire project, because most of the Code is maintaine

Parent process file Handle Quilt process occupationScenario Description:1. Parent process A uses the function fopen to open (create) a disk file file.exe.tmp2. Parent process for long-time side-download side writes3. When the download is complete, close the file handle using fclose4. Rename File.exe.tmp to File.exeThe above is the ideal code execution process.Problem:In the fourth step, renaming the file may fail, using the GetLastError function to di
Some time ago, I learned how to use git, and then git the Linux source code. But at the same time I want to go to the famous development tree mm tree in Linux under git. I found that the tree maintained by Andrew Morton is composed of other trees (such as the Development Branch of the kernel) and many individual experimental patches, it is not managed by git, but managed by the quilt developed by him. So I learned how to use
parent process are inherited by the child process:• Actual user i d, actual group I d, active user I d, effective group I d.• Add Group I D.• Process Group I D.• Conversation period I D.• Control terminals.• Set-user-I d flag and set-group-i-D flag.• current working directory. • root directory.• File mode to create a masking word.• Signal shielding and alignment.• Close flag on execution of any open file descriptor.Environment• Shared storage segments that are connected.• Resource limitations.T
What is a "sub-process? That is to say, in my current shell situation, open another new shell, and the new shell is a sub-process. In general, the custom variables of the parent process cannot be used within the child process. However, after the variables are changed to environment variables through export, they can be applied under sub-processes.
The child process only inherits the environment variables of the parent process. The child process does not inherit the custom variables of the paren

to an intrusion detection and defense software named "Strata guard" produced by StillSecure, it is a real IDS/IPS software with intrusion detection and active defense functions.
Strata guard is a commercial software based on Linux, but its free version has no limits on all other functions except for its maximum network bandwidth limit of 5 Mbps. 5 mbps bandwidth is sufficient for small and medium-sized ent
detection commands, this is a big problem for users who are not used to command line operations.
Therefore, a lot of software has emerged on the market that uses Snort to provide intrusion detection functions. However, these software only misappropriates simple functions and even does not have basic intrusion detection settings, let alone the intrusion defense function. In this article, I will introduce you to an intrusion detection and defense software named "

According to Still, dream back to the embroidered Sapporo. The distant mountain imagines, the amorous glances ripples. In the evening, with Iraq painted eyebrow. "(The wearily.

1. Random Sampling in SAS:
1. sample sampling is often required in actual data processing. There are two main situations in practice:
(1) Simple sampling without repetition(2) stratified sampling a. Proportional stratified sampling B. Unequal stratified sampling;
2. The proc suveryselect process can be used in SAS to achieve various sampling:
The general form is:
Proc surveyselect DATA = Strata ID Run;
Note: The method is used to specify the random sa
significant of treatment effect before the rollout of Post-stratified Metri C. We call thisas Sample Average treatment Effect (SATE),· Post Stratification AdjustmentFrom above formula, we can see that thevariance of sample mean are split into Within-strata variation andbetween-strata var Iation, and the Between-strata variance is removed bystratification. The mo
The strata guard intrusion detection and defense software encapsulates the snort and provides a graphical interface.
Strata guard has high performance requirements on the dependent hardware, mainly to ensure sufficient network forwarding performance while detecting all network traffic. For the free version of strata guard, we can use the following hardware to cus
