Senior internship Summary

Internship summary:

During my senior internship, I chose to stay in school to develop the operating system. After more than two months of practice, I felt like this, regardless of my knowledge, ability, life, or progress.

In terms of knowledge, the operating system is not a peak for Chinese college students. At first, I chose the operating system to prepare for the implementation of the ruip protocol and build a platform. According to the operating system knowledge of Mr. Luo and the embedded knowledge of Mr. Wang, I think I can try to do it. As long as I work hard, as long as I have the help of teachers and students, this should be done. After two months of development, 3000 lines of code have been completed, including interruptions, process scheduling, memory management, hard drive, and multi-thread, large hard drive ( 128 GB ), 4G Memory addressing space. In the process of development, I will part of my knowledge, feelings, design written in the csdn blog (http://blog.csdn.net/cloud_apex ). at the end of last semester, a netizen on the Internet also wanted to write my blog in the apex operating system. This was a great help for me, he will help me complete the DMA driver, Floppy Driver, serial port, and parallel port driver. In the next month, I will focus on VESA programming and try to give apex a nice graphic interface.

During the preparation of the operating system, I felt that the operating system resources in China were extremely poor! Many documents must be found on a foreign website. I also collected a lot of good information during the development process. I think this will be helpful for open-source communities in China.

Writing an operating system has improved my capabilities. I used to be familiar with writing upper-layer applications, such as J2EE. Now I am getting familiar with hardware programming and operating systems, I think that in the near future, I will be a versatile operator, and I will do what I want to do. There is an old saying: to understand a person, you must understand his history. This is also suitable for programming. To better understand the advantages and disadvantages of your own applications, you must understand its underlying platform. Only by understanding its underlying layer can you better write applications.

The significance of the operating system is the meaning of my life. Challenge the peak and pursue the freedom of the program. Someone once asked me why you are not in a hurry to look for a job. I watched everyone looking for a job as quickly as possible, but my heart was still like a lake. I told him that I was full of food, I am really full! In his motivation theory, Maslow, a western humanistic psychologist, clarified the theory of human needs. He divided human needs into seven layers, from bottom to top: physiological needs and security needs, social Needs, respect needs, knowledge needs, aesthetic needs, self-realization. I have enough food to wear now. I don't have to worry about it. I went out to work, and my time was short. Why don't I pursue the seventh floor during the last time of college, implement yourself. Maslow believes that self-realization is "what can be achieved, what desire can be achieved", to give full play to their various talents. This is self-realization. In fact, most Americans are full. Otherwise there would be a computer and a third scientific and technological revolution. If Einstein was hungry, there would be no theory of relativity in human social science.

During the past two months of practice, some unhappy things also occurred, that is, I was ill and had never been cured. It was delayed and eventually slowed down to a chronic state, at the end of the semester, my body was basically in a sub-health status. I had a continuous cold and fever, but now I am not finished yet. It is painful! Therefore, I only hope that after completing Apex Origin Edition, I can change my living habits. The time for computer reception can not exceed 3 hours, but not more than 1 hour in a row. People, the most important thing is the body. The old man is the least aware of this, and the young people do not know it. It is really not listening to the old man's words and suffering!
