Why should programmers use Linux?

##Most people recommend Linux, basically Everyone will say that Linux makes you more efficient and better.

But tools are just tools.

#But tools are just tools.

#But tools are just tools.

The difference between good programmers and poor programmers is first of all the difference in attitude.

They have their own ideals and think a lot. Whether before the project starts or during the project, they will also summarize after the project is completed.

They treat problems more rigorously and think more comprehensively. They must have gone through some thinking before starting to write code and estimate the problems that may be introduced.

Poor programmers treat problems more casually, that is, their attitude is not so serious, and their code is written more casually: they will not realize that their code has polluted the entire project.

In addition to the difference in attitude, there is also a big difference in ability.

When encountering a more difficult problem, excellent programmers can always start from the principle, see the real cause of the problem sharply, and then solve the problem, while poor programmers always stay on the surface——Thinking that Linux will make you excellent is just staying on the surface. Only you can make you excellent.

So what are the benefits of Linux?

Open Source

I don’t think I need to explain this.

##Multi-user, multi-task, multi-thread

Linux system can support multiple users at the same time. Each user has special rights to their own file devices, which can ensure the communication between each user. They do not interfere with each other, just like having an assistant on your mobile phone. You can log in to multiple QQ accounts at the same time. When the hardware configuration is very high, each user can also perform multiple tasks at the same time, multiple threads work at the same time, and improve efficiency. It is simply perfect. It's a mess, and it outshines other operating systems in terms of multi-users alone.

Stability and Efficiency

You may hear that a Windows server suddenly crashes after running for a long time, but you will never hear that a Linux system server freezes because it has not been shut down for a long time. , this situation almost never occurs on Linux. The Linux server can run endlessly without downtime because it inherits the excellent stability and efficiency of Unix. It is precisely because of its stability that it has won the favor of many users. Because of its efficiency, its scope of use is broader. However, Linux can also provide some high-reliability services, such as: LNMP, virtualization, database services, etc.

Security and SELinux

Its security is much safer than other systems. Because Linux has a large number of users and open source community support, system vulnerabilities can be discovered quickly. , and quickly releases security patches and updates in a timely manner. It also has strong "immunity" characteristics and is rarely attacked by viruses. For an open system, while it is convenient for users, it is likely to have security risks.

However, using Linux’s own firewall (iptables, firewalld), intrusion detection and security authentication tools to promptly patch system vulnerabilities can greatly improve the security of the Linux system and prevent hackers from taking advantage of it. There is also a security enhancement mechanism SElinux, which provides mandatory access control in the Linux kernel. It has very comprehensive functions and can protect systems and services well. However, many people like to turn it off, which is not very safe.

Tcp_wrappers can also provide good network service access control. The Linux system is also very good at managing user and file management permissions. It can control permissions very well and ensure the confidentiality of files, which is unmatched by other systems. , so the Linux system is indestructible to a certain extent.

5##Performance Advantage

Since Linux needs to ensure its stability, the kernel is not as bloated and full of loopholes as other operating systems. As the Linux kernel is constantly updated, To improve its advantages, the Linux operating system can fully reflect the hardware advantages of the server, because the Linux system has absorbed nearly a quarter of a century of development experience of the Unix system. The most important thing is that Linux is open source code to ensure system stability and better Call hardware functions, and also provide a wealth of system resource tools top, freee, df, vmstat, dmesg, iostat, sar, uptime, etc. to easily check resource utilization.

The above is enough to make you fall into the arms of Linux.

Of course, in addition to these, there are some unknown things, such as:

bigger than bigger

Take your Linux system Go out and start doing stuff with the command line.

For example, enter sudo rm -rf /*

In the eyes of laymen, it is very cool!
