A freshman student's questions and answers about future technology directions

"Letter"
Mr. Zhou:
Hello!
I am a freshman majoring in computer science, first of all thank you very much for reading this letter.
My freshman major has tried Java Web background development and Linux C + + background Server programming Two technical directions, a total of 30,000 lines of code volume accumulated.
I would like to ask you to help me to point out the question is:
1. Online Many people think that Linux server development learning difficult, long cycle, the stamina is big, I myself also feel that learning this is actually more difficult than Java Web development, involving the operating system, the underlying knowledge more.
What do you think of the long-term development of this technical direction after employment? How's the stamina?
2. Online predecessors said: "The needs of the server is still a minority, a variety of services have matured, we are to take a mature to use, and seldom will go to the new development of one, that is, difficult and not pleasing, so the opportunities in this area are relatively small."
What do you think of the current and future employment prospects and supply and demand of Linux C + + server-side development?
3. I would like to learn specialized courses in the future under the premise of specialized in Linux c++/c background server-side programming, employment to find this aspect of work; but I always worry about the future in the Linux C + + road will be more difficult to go, not to the name of the company's requirements for fresh students, Can not achieve their pre-set goals: After graduating from the university can enter the bat work.
How should I look at and solve my problem of this idea, as you have seen as an experienced?

Thank you again for taking the time to read this letter, and the students are sorry to take up your rest time. I wish you a happy life and smooth work.

Sincerely
Salute

Classmates:
How are you doing!

Thank you very much for your letter! As a freshman, you can accumulate about 30,000 lines of code, which is pretty good. I believe that you will have more outstanding achievements and better performance in the future study.

You said in the letter to the Linux server development, I am sorry that I did not engage in this development work, so I can not give you a detailed explanation of the technical direction of the status quo and employment prospects. But for a software or industry, it will undergo a rapid development period and a smooth maturity, specifically:
(1) In the rapid development period, many companies will strive to enter the market to share, so the demand for talent is very large, like the current mobile phone client development.
(2) in a stable mature period, there will be a large number of major giants occupy the majority of the market share of the situation, this time the need for talent is relatively small. The major companies recruit people, but also mainly engaged in software system optimization, reconstruction and other aspects of the work. The Linux C + + server-side development that you mentioned in your letter should be at this stage.

However, it is not because an industry is already more mature, we think there is no prospects for development. For any technology, as long as you delve deep enough, are the major enterprises to seize the talent. Moreover, background development involves a lot of operating systems, compiling principles, the principle of computer composition and other underlying knowledge, learn this knowledge, you can find a lot of related work, not just Linux c++/c backend server development. Many of the best programmers I know have a pretty good understanding of the bottom, and you're right to work in that direction.

By the way, you are only a freshman now, there is no need to set your future in a certain technical direction. While learning good Linux c++/c backend server development, you should also learn some other aspects related to things, such as mobile client development, and pay attention to the latest technology trends, to become a person with the times.

Finally, while learning, you should also learn to share, and write your own learning experience as an article to a forum or blog. Thank you again for your letter, my new book "C Programmer: From the campus to the workplace" will be published, please pay more attention!
