There is a clear electronic version on the Internet (in English), with a total of 913 pages (including 789 pages of the body) in the full text. Due to the loose gap in the book, many charts, and many repeated content, therefore, although the book is thick, it will be faster to read.

 

Reading Strategy

This book focuses on reading and adopts the following strategies:

First, read the entire book and make some excerpts and notes during reading (some are directly recorded in PDF files and some are recorded in the mybase desktop tool). If there is something unknown, it will not affect subsequent reading, I will not go into details after having a holistic understanding. Some chapters have a large number of contents, but the non-core content can be understood briefly and the concept of integrity is enough.

After reading the book for the first time, I summarized the content and structure of the book in my mind (taking a blank sheet of paper and a pen, without looking at any material to draw the content and correlation of the book ), based on the purpose, you can differentiate which chapters need to be read again, Which chapters can be skipped for the time being, and which chapters have been mastered. Just take a look at the key points. Then the second round of more purposeful reading will be conducted. Of course, application in actual projects is the best way to master the technology, but before that, by reading excellent books to form a holistic concept, I believe it will get twice the result with half the effort.

It takes about 40 hours to read this book from April 12 to May 2. Now is the summary after the first read-through.
