• "In my experience, most stuff that you start is mediocre for a really long time before it actually gets good. And you can't tell if it's going to be good until you're really late in the process. So the only thing you can do is have faith that if you do enough stuff, something will turn out great and really surprise you."

  --- Ira Glass: The Wrong Stuff

• "A computer program is said to learn from experience E with respect to some task T and some performance measure P, if its performance on T, as measured by P, improves with experience E."

• Summary:
  This course is intended to introduce the fundamental concepts that modern operating systems use to manage the physical computer. Students will understand the operating system kernel. The core of the course focuses on OS support for concurrency (threads) and synchronization, resource management (CPU, memory, I/O), and distributed services (optional). The practical component of the course teaches multithread programming, inter-process communication, and distributed interactions via RPC.
• Prerequisites:
  Knowledge of C/C++ and Computer System Organization. Any experience using command line interfaces in Linux will be useful when creating and building projects for this course.
• Textbooks:
  • Operating System Concepts (7th or 9th edition), by Abraham Silberschatz (homepage)
  • 操作系统概念，西尔伯莎茨编著（第七版英文影印版，高等教育出版社，2010年）或者（第九版中文版，机械工业出版社，2018年）.

  • Linux命令行与shell脚本编程大全 第3版, Richard Blum Christine Bresnahan, John Wiley & Sons, 2015.
• Extensive Readings:
  • 课程实验主要基于Linux操作系统。同学们已经会使用Windows操作系统，为什么还要在课程中安装学习Linux？我们的回答：Linux以其广泛的基础应用各大行业领域，逐渐成为互联网时代的常青技能。业界主流操作系统、软件开发环境、互联网企业级应用都是基于Linux操作系统。金融、互联网、教育、军工等各行各业都离不开Linux，一直以来Linux都是物联网、云计算、人工智能背后的无名英雄。具体参考“为什么要学习LINUX和云计算？”
  • The online course UC Berkeley, EECS CS162: Operating Systems and Systems Programming uses the same textbook as we do.
  • A good online operating systems book titled Operating Systems: Three Easy Pieces is provided by Prof. Remzi H. Arpaci-Dusseau and Prof. Andrea C. Arpaci-Dusseau from computer science department of University of Wisconsin–Madison.
  • A free online course on Advavanced Operating System is taught by Professor Kishore Ramachandran at the Georgia Tech University. Video files for lectures can be downloaded, and please use the VLC player for viewing.
