interactive form of these products, so that users easy to use, without the need to learn a new set of interactive form (the cost of re-learning is very large). 1. Mailbox VS Notification Center mailbox is a line of communication tools to save all the mail records for easy viewing, our system also needs a similar function, but do not need to write mail, do not need to see who the sender is. The following

After the acceptance of the computer room charging system, the study of "Software Engineering", and then refer to the GB8567-88 standards, and try to write a document on the entire life process of the computer room charging system, have a preliminary understanding of the document.The purpose of providing documents can be divided into three parts: development, management, and guidance.1.

went to the class with my boyfriend to study Liu Yan Teacher's course. After studying in the newspaper class, we learn more systematically than before. And, of course, there are more topics to discuss with my boyfriend. We also often quarrel with each other because of the problem of anger and good, and in such a process, my boyfriend and I also warmed up a lot of feelings.After graduating last year, through the school recruit boyfriend in a network company engaged in operations development work

Syslog log systemThe second is to use file to customize the log information saved filesNote: A category can use multiple channel to save log information, but a channel can only hold one category log source information.The DNS log system needs to be defined in/etc/named.conf.For example, define the DNS log system format as followsLogging {Channel My_query {File "/var/log/named/log.query" versions 3 size 10k

services can be implemented either by command or by graphical means:(1). Command mode: In character mode you can use the command to set the turn on or off service, the setting command is: NTSYSV, after executing the command as shown:Use the cursor keys or mouse to move the scrollbar to the service item you want to set, press SPACEBAR or click the option box with the mouse, select * indicates, if you do not need the service, then press the SPACEBAR or click the option box with the mouse, no symb

Summary: four methods are helpful for learning the Linux system.The Internet is a magical thing. modern people's life is inseparable from the Internet. The Internet has penetrated into people's work, life, entertainment, and other aspects. Network is everywhere because it provides many network services, so network services are the soul of the network. Various network services on the Internet are deployed on a variety of servers. A Server is a physical

Introduction Waffles English is originally intended to be a honey cookie, but here it refers to a very powerful machine learning open source Toolkit. Waffles contains many algorithms, involving all aspects of machine learning, the recommendation system is located in the Waffles_recommend tool, probably only 1/10 of the entire waffles content, and other classifica

philosophical ideas exist, recorded under the understanding of the Linux operating system philosophy.All documents (Linux almost all the resources are abstracted into the form of files, even the hardware, network communications using sockets and pipelines are so), the file is a set of boundaries in the storage device streaming data.Second, by a number of small functions of a single program, combined together can achieve complex tasks, each small prog

Sendmai and qmail services to build mail servers, using NFS and iSCSI to build network storage server, Linux in the enterprise application of a very wide range. Linux supports multiple users, each user has their own special rights to the file device, to ensure that the user does not affect each other. Multitasking is one of the most important features of computers now, and Linux allows multiple programs to run simultaneously and independently.In the network devices are generally Linux operating

develop a good Linux operating habits. When you get into Linux, don't think about it in the way that Windows works, because there are really big differences between them, such as the memory management mechanism, the process mechanism, and so on, so, to put aside the thinking of Windows, Trying to tap into the unique potential of Linux with a new concept is essential for beginners. The most important thing is to be accustomed to the command line operation mode. Linux is a command line composed o

There are a lot of specific application scenarios.Cross-multiplication: The cross-multiplication is also called the outer product, and the result is still a vector.Given 2 vectors, when determining the method of its cross-multiplication, there is the law of the right hand (the 3-dimensional coordinate system is the coordinate system of which hands are used for gestures).
