This book takes an approach that is close to the hardware, introducing addresses, pointers, and how things are represented using binary. An important idea is that everything is a bit pattern and what it means can change. As a C developer, you need to think about the way data is represented, and Harry Fairhead encourages this. He emphasizes the idea of modifying how a bit pattern is treated using type punning and unions. This power brings with it the scourge of the C world – undefined behavior - which is ignored in many books on C. Here, not only is it acknowledged, it is explained, together with ways to avoid it.

This book looks at searchable storage in cloud computing. It introduces and presents new schemes for exploring and exploiting the searchable storage via cost-efficient semantic hashing computation. Authors Dr.Yu Hua and Dr. Xue (Steve) Liu cover topics from basic hashing structures (Bloom filters, locality sensitive hashing, cuckoo hashing), semantic storage systems, and searchable namespace, which support multiple applications, such as cloud backups, exact and approximate queries and image analytics.)

This short book is ideal for front-end developers who need a rapid introduction to Vue.js. Author Nilson Jacques shows how the component-based architecture of Vue.js is designed to be flexible and easy to adopt, making it just as easy to integrate into projects and use alongside non-Vue code. If you've already used a component-based JavaScript framework such as React, you'll find this book an easy read, but it's also suitable for readers with no prior experience of such frameworks.
