- How an IT person can become a cloud computing engineer
- Before people understand how to become a cloud computing engineer, they first need to understand what cloud computing is. Cloud computing is a scalable method of providing computing-related resources over the Internet. The engineering discipline applied to this concept is called cloud computing engineering, which is associated with any technology related to cloud computing. Cloud computing builds a systematic approach that focuses on the standardization and governance of cloud computing applications. Cloud computing engineers mainly focus on a few key cloud services: Infrastructure as a Service Platform as a Service Software as a Service Cloud computing engineers are IT professionals who are responsible for any technical issues related to cloud computing. Their responsibilities include support, maintenance, design, management, and planning. Multiple job positions focused on different types of computing are related to Cloud Computing Engineer: Cloud Computing Security

- Linux File Systems: Characteristics of File Names, Case, Extensions, and File Types
- On Linux, any software and I/O devices are regarded as files and the file name in Linux supports a maximum of 256 characters, which can be named with A~Z, a~z, 0~9 and other characters. Unlike Windows, file names in Linux are case-sensitive, and all UNIX series directories follow this rule. There is no concept of c drive (such as C drive, D drive) under Linux, but only directories. Different hard disks are mounted in different directories. It is reported that Linux files do not have extensions, so the file name under Linux has nothing to do with its type. For example, abc.exe can be a text file, and abc.txt can also be an executable file. Text under Linux

- Learn Bash skills in the game
- Whether you're a newbie or a veteran, there are always fun ways to test your BASH skills. In this tutorial, I'll explain how to test your BASH skills by playing a command line game. In fact, technically speaking, these are not real games like SuperTuxKart, Need for Speed or Counter-Strike. These are just gamified versions of Linux command training courses. You will need to complete a mission based on certain instructions from the game itself. Now, let’s take a look at a few games that can help you learn and practice Linux commands in real time. These games are not just time-killers or mind-blowing, these games will help you get a real experience with terminal commands. Read on: Test your BASH skills with ‘Wargames’ Here’s

- In-depth analysis of the kernel source tree: the synergy between Kconfig files and Makefiles
- Principle Each directory in the kernel source tree also contains a Kconfig file, which is used to describe the kernel configuration menu related to the source code in the directory. The Kconfig files in each directory constitute a distributed kernel configuration database. When configuring the kernel through the makemenuconfig command, the menu storage technology principle analysis is read from the Kconfig file: Based on the linux26 kernel source code, the configuration is saved to a kernel configuration file named .config for use by the Makefile when compiling the kernel. The Makefile at the top of the source code directory tree is the entrance to the entire kernel source code management and plays a decisive role in the source code compilation of the entire kernel. When compiling the kernel linuxc, top

- How to solve the problem of automatic line break conversion in Git
- I used to work on Linux, so I didn't encounter the problem of file line separators when using Git. Now I suddenly switched to using Git on Windows and found that files that turned out to be Unix file line terminators were displayed when using gitdiff. All lines are modified. The cause of this problem is Git's clever "automatic newline conversion" function. There are several ways to fix this problem. When installing "Git for windows", on the "Configuing the lineending conversions" page, change the default selection to "Checkoutas-is, commitas-is" if it has already been installed.

- Keep Linux accurate time
- How to keep the correct time, how to use NTP and systemd to keep your computers in sync without abusing time servers. What is its time? Linux is weird when it comes to telling you the time. You may think that you are using the time command to tell you the time, but it is not because time is just a timer that measures how long a process has been running. To get the time, you need to run the date command. If you want to see more dates, you can run the cal command. Timestamps on files can also be a source of confusion, as there are two different ways to display them, depending on your distribution's default settings. Here is an example from Ubuntu16.04LTS: $l

- Explore file types in Linux systems: ordinary files, directories, and special files
- The following sections discuss the several file types in the Linux system and the basic functions of performing I/O when developing C language in Linux. However, in the process of giving examples and experiments, there are several file types in the Linux system, all of which revolve around ordinary files. File types in Linux Remember in Section 9, when we talked about the Unix system (Linux is a Unix-like system) that "everything is a file"? Most files in unix systems are ordinary files and directories, and these two types of files are also the most commonly used. For example, the /usr directory and the hello.txt text file above it belong to ordinary file types. In fact, linuxsite:infoq.cn, the Linux system divides all files into

- Detailed explanation of two ways to merge git code
- This kind of merge of gitMerge merges the history of two branches together. The existing branch will not be changed. It will compare the different files of both parties and cache them, generate a commit, and push. Advantages: safe, existing branches cannot be changed. Will be modified Disadvantages: It will more or less pollute the branch history, and it will increase the difficulty of understanding the project history when looking back at the project. Uses: Generally used for the public master main branch gitRebase. This kind of merger is usually called "rebase". It is to modify the commit history, compare the commits of both parties, then find out the differences and cache them, and then push them to modify your commit history. Pros: Project history will be very tidy Cons: Security and traceability are poor, you won’t be able to tell

- Functions of the ping command and differences between Linux and Windows systems
- The function of the ping command is to test the network connectivity between hosts. It sends out data packets based on the ICMP transmission contract to test the Linux network delay, and requires the other host to reply. If there is no problem with the network function of the other host and the firewall allows the traffic, Then the information will be replied to, and we will know that the other party's host system is online and running normally. However, it is worth noting that there are certain differences between Linux and Windows. The ping command under the Windows system will send out 4 requests and then terminate the command manually; while the Linux system will not terminate manually and requires the user to automatically press the key combination." Ctrl+c" to end, or add the -c parameter when initiating the command to limit the number of messages sent. Test environment: Ce
