Choosing the Best Book for Initial Learning in Network Programming: APUE or UNP

When deciding between Advanced Programming in the UNIX Environment (APUE) and Unix Network Programming (UNP), it's generally better to start with APUE. Here are the reasons why, as well as a comparison and recommendation based on extensive experience with both books.

Foundation Knowledge

APUE provides a solid foundation in Unix programming, covering critical topics such as process control, signals, threads, IPC, and interprocess communication (IPC). This comprehensive coverage is essential for building a strong base before diving into more specialized areas of network programming. A well-rounded understanding of these basics is crucial for developing robust tools and utilities, especially in the Unix environment.

Incremental Learning

APUE is structured to gradually introduce and build upon key concepts. This incremental approach is particularly helpful for newcomers to the field of network programming. By starting with manageable and foundational topics, you can gradually progress to more complex and advanced subjects. This method allows for a deeper understanding of the underlying principles, making it easier to tackle more challenging aspects of network programming later on.

Comprehensive Coverage

One of the standout features of APUE is its inclusion of practical examples and explanations. These elements are crucial for gaining a clear understanding of how network programming actually works in the Unix environment. The book provides a thorough exploration of Unix system calls and libraries, which form the backbone of many network applications. By studying these examples, you can effectively translate theoretical knowledge into practical coding skills.

Prerequisite for Advanced Topics

APUE serves as an excellent prerequisite for more advanced topics discussed in UNP. While UNP is highly specialized in its focus on communications issues, it is less comprehensive in other areas. By mastering the fundamentals in APUE, you ensure that you have a solid foundation upon which to build more advanced network programming techniques.

History and Context

The first editions of APUE had chapter 7 on network programming redacted due to bugs and omissions in the source code examples. This chapter was redacted after receiving feedback from users and experts in the field. Although the remaining content is valuable, the networking chapter is not as strong as it could be. Despite this, APUE still covers a vast array of critical aspects that are fundamental to Unix programming.

Complementary Learning: APUE and UNP

Given the strengths and weaknesses of both books, it's recommended to start with APUE to build a strong foundation. Once you have a solid understanding of the basics, UNP can be read for deeper insights and more advanced techniques. APUE has several chapters that are key for understanding network programming, including process control, signals, threads, and IPC. These topics are crucial for writing concurrent and efficient network applications.

Recommendation

Prakash Gamit, an experienced professional in the field, agrees that starting with APUE and then moving on to UNP is the best approach. Whether you are a beginner or an experienced programmer, this order can provide a comprehensive and well-rounded learning experience. By starting with the basics and gradually advancing, you can ensure a deep and enduring understanding of network programming in the Unix environment.

Conclusion

In conclusion, while both APUE and UNP are valuable resources for learning network programming, the recommended order is to start with APUE. This approach allows you to build a strong foundation before delving into more specialized topics. By following this structured method, you can gain the skills and knowledge necessary to develop robust and efficient network applications.
