When compiling the Linux kernel source code, the DRIVERS/MD directory will generate multiple KO files, then which one of these kernel modules to load first, which after loading? For example, Md-mod.ko, Raid5.ko, Raid10.ko, are these modules loaded together or in a sequential order? If you are familiar with Linux kernel programming, you know that there is a request_module function that asks to load a module,
[Rrdtool] Monitoring and automatic drawing, simple monitoring. md, rrdtool. md
Now I want to monitor the traffic and concurrency of the service, but I don't have much time to write the system. Other O M systems are unfamiliar, therefore, the existing rrdtool shell is used for a simple monitoring interface. Temporary use is also a small experiment. Rrdtool is just getting started. It's a small exercise.
The difference of realization way: col-md-offset-*, is realized by using Margin-left, col-md-push-*/col-md-pull-* is realized by using relative position.
The difference between the effects, col-md-offset-* can only be cheaper to the right, because the implementation is margin-left, and push/pull because it is relative

As a test engineer, the developers who have the most contact in daily work are of course the development engineers in the team. How to communicate effectively with the development engineers is an important issue facing the test engineers. In general, there are always developers who like and dislike test engineers in a
Introduction to web Front-end engineers and introduction to web engineers
This article is intended for beginners who want to get started with the web Front-end project. If you are an expert, please pass by. You are also welcome to make a brick.

If you are a talented engineer (you can leave immediately), you can accomplish many tasks independently. You can be a strange person, because I believe no one will not admire you. But the reality is true. Most people are not geniuses, and we are not alone in the workplace. We need teamwork, coordination, and coopera
For example: md d: \ test, you can also use MD test to create the test folder in the current path.
If the folder to be created contains spaces or , enclose the folder name in quotation marks, for example, MD "test ABC" and MD "ABC XYZ ". What will happen if no quotation marks are used?
The test result is:
1. If t
For example, MD D:\test can also use MD test to create a test folder under the current path.
If you want to create a folder with spaces or ampersand, you need to enclose the folder name in quotation marks, such as MD "Test ABC", MD "ABCXYZ". What would be the consequences if you didn't use quotes?

In the MD module, all levels of RAID are used by a copy of the bitmap source code, that is, a common bitmap process, the following RAID1 use as an example to analyze how bitmap works.When using the RAID1 disk array, there is a high demand for the reliability of the data. In the process of writing, there may be unstable factors, such as disk damage, power down/down, network failure, system failure, and so on, resulting in write failure, after the syste
Recently spent some time seriously studying the MD code, and on the basis of the original code to develop a series of new functions, these new features to make MD more complete, more suitable for large storage enterprises, by adding array caching and bitmap optimization greatly improve the storage speed, improve the reliability of the data, In the case of any power off, the data consistency is guaranteed, t

First, briefMD5 algorithm is a typical message digest algorithm, its predecessor is MD2, MD3 and MD4 algorithm, which is improved by MD4, MD3 and MD2 algorithm. Whichever MD algorithm, they all need to get a random length of information and generate a 123-bit message digest. If this 128-bit binary summary information is converted to 16, you can get a 32-bit string, so the majority of the MD5 algorithm we see the digital fingerprint is 32 16 binary str
