The low-key Linux system quietly changed the way of life in the human world

Do you know what operating systems are? Windows.

This was a question I asked before I went to college. At that time, I thought there was only one operating system called Windows, but I was wrong. After I went to college, as a computer science student, I came into contact with an operating system other than Windows for the first time, which was Linux. After that, I installed a virtual machine by myself and installed the Linux distribution of Red Hat system on it. In my sophomore year, I took Linux-related courses. After the teacher's recommendation, I bought a book "This is How to Learn Linux", which allowed me to start my Linux journey. I feel more and more that Linux is everywhere in our lives, closely related to our lives, and very close to our lives. Today I hope to record my learning experience and share it in this article.

1. The Importance of Linux in Life

In fact, everyone is using Linux every moment, but you just don't know it. It can be said that Linux has become a foundation in our lives, such as the control system of airplanes, the system of banks, the system of mobile phones, etc. You can imagine what our life would be like without the above things. Our lives, money and lives are in the hands of Linux. It can make us survive, and it can also make us perish. Therefore, the importance of Linux is almost unbelievable. The world without Linux may be completely different. Perhaps, such a world will be dimmed and dark, and Linux will be the reason why that world will no longer exist.

2. The manifestation of Linux in life

Linux has long been a leader in the server space, largely due to its stability, security and low total cost of ownership (TCO). However, what many people don’t realize is that Linux has already penetrated into every corner of our lives and has been benefiting our lives.

1. Android

The first thing to mention is of course Android, a mobile phone operating system based on Linux developed by Google. I believe everyone is familiar with it. Google created Android, a new operating system, by improving Linux, opening a new era for people's lives and making everyone's lives more and more exciting. Android has brought Linux to countless mobile phone users around the world. It can be said that it is the most successful product of Linux in the mainstream field so far.

2. Set-top box

You may not have thought that Linux is inside this essential gadget. It is the core responsible for transmitting streaming video, handling inter-process communication and other tasks. Network video playback devices with Linux as the core allow users to watch movies on the website and experience more wonderful worlds.

3. ATM

When we go to withdraw money, have you ever thought about why we can withdraw money from different places and whether our money will be stolen by others? If the bank's system uses Windows, we should really worry about it, because the security of Windows is far from enough, and most hacker attacks and viruses are aimed at Windows systems. At present, Linux provides better security performance than Windows.

4. Government agencies

The government is the core of the country, and information security must be taken seriously. They will not use Windows, which has poor security. In the United States alone, government-level users of Linux include the United States Postal Service, the Department of Defense, and the Federal Aviation Administration. Government agencies in France, Spain, Germany, Switzerland, and many other countries have also chosen the Linux system.

5. Game Server

The server must be stable and secure, and it needs to run for a long time without being shut down. Windows can hardly do this, but Linux can, giving game enthusiasts a better experience.

6. IBM’s Watson supercomputer

Finally, it is worth mentioning that the IBM Watson supercomputer, which has recently become famous for its outstanding performance in the "Edge" competition (man vs. machine), also only uses Linux as its operating system.

These are just a small part of the practical applications of Linux in our daily life, but they are enough to prove the value of this open source operating system. Then we should study hard, learn more about its functions, create more wealth, and experience a better life!

3. How should we learn Linux?

Before learning, you saw that Linux has so many uses, did you feel that it would be difficult to learn? In fact, it is not difficult to learn as long as you find the right method. After learning the basics, these things are actually the same. It doesn't matter whether you take a class or not. The most important thing is that you have an interest and a firm belief. Don't stop learning just because it's a little fun. If you can't persist in learning, then you are not suitable for learning. You should learn something else.

First of all, there must be an environment

At the beginning, many people asked which Linux distribution is good? In fact, they are all similar, and most of the knowledge points are the same. I used redhat at the beginning and felt very good. Of course, you can also use Ubuntu or other distributions.

Then, finish reading a book carefully.

At the beginning, I kept looking for videos on the Internet, but the videos were so mixed that I didn’t know how to learn or what to learn. Later, I was very glad that my teacher recommended the book "This is How to Learn Linux" to me, and then I started to study systematically. More importantly, this book also has videos, which can help me learn well. You can search it on Baidu: http://www.linuxprobe.com/chapter-00.html.

There are some places to answer questions

For beginners, it is impossible not to encounter problems during the learning process, so how to solve the problems is the key. The first thing we think of is Baidu. Baidu is indeed a good thing. We can usually solve most of the problems. But here I recommend a platform for learning the same thing together. If you want to learn STM32, you can go to Zhengdian Atom. The book recommended above also has a special forum. Everyone can communicate with each other about what they don’t know or don’t understand. There is also a QQ group. A group of like-minded people get together and it will be easier to solve problems. This is also the case with this book. It has its own Q&A group to facilitate solving problems encountered in learning.

Linux is closely related to our lives, affecting our lives all the time, and also requires us to create more valuable things.
