Summarize the recent situation

Since it was only when the school started in March, I learned that there were spring recruiting interns, so I only prepared for a month to participate in the written test and interview. I bought a book to read, but it was just a fast-food study, and it was completely prepared for the interview. Of course, I still read nearly 2/3 of the two books "C++ primer" and "Analysis of STL Source Code", and I have benefited a lot, but the knowledge of computer network, operating system, and Linux is only a cursory look, and I soon forget it. This is not a good sign.
Self-awareness, learning things in the computer industry can't be so utilitarian, you must look at it down-to-earth. Next, I plan to retreat and read books. In addition to the content of the course, I will first read the computer network, and then fight the operating system. The programming is all changed to the Linux side, edited with vim, compiled with g++, and debugged with gdb, so as to lay a solid foundation. Don't ask for speed, just want to learn things well and remember.
