Ruby Meta programming White Magic Book

In Ruby's world, programmers enjoy all kinds of bizarre grammatical sugars, and also go through a variety of traps. And it's all about Ruby's powerful metaprogramming capabilities. Metaprogramming is like the magic of the Ruby World, and when it is white magic can help you to make the program very concise, beautiful, and when it is dark magic, you will be lost in some difficult to explain the bug. Ruby Met

Algorithms book reviews Hello everyone, I am a translator

I just handed in the Chinese translation. I strongly recommend this English version. This is an algorithm book suitable for self-study and teaching materials. Compared with it, Tsinghua's algorithm textbooks are simply for primitive people. What are its characteristics?1.

Recommend a starter book for algorithms

Recommend a very good algorithm for getting started books:"Algorithm design and Analysis Basis" (2nd edition), (United States) Anany Levitin, Pan Yan translation.In addition to "thinking in Java", this is another book I have read two-thirds of the content and want to keep on reading. This book is very good, can feel the author is trying to close to the reader, the explanation is clear and easy to understand

Data structure with Algorithms (Hedgehog book) reading notes----catalogue

Recently in grasping the underlying language foundation, before the data structure and algorithms do not have much feeling, but the more deep learning the more I feel that these foundations are really to hold firmly. A simple array, a lot of learning to dig into. So I'm going to write a series of reading notes and comb the basics of this piece. This book is a JavaScript description of the data structure bud
