Open-source development has been the single most significant contributor to the development community, and the contributions are used across the IT landscape including corporations, universities, schools, etc. Despite being highly popular, contributing to open-source and navigating open-source systems has always been challenging. Some reasons could be that most open-source developers hold other day jobs, which might also be their regular work. 

Memcached is one of the largest commercially and non-commercially used caching systems in the IT world, with a relatively smaller codebase that enables developers to understand the basic skeletal of source code structures while enabling developers to hone their skills towards the development of high-quality production-grade, enterprise-ready open-source software. Most server-based technologies.

Open-source development skills enable developers to understand the intricacies of softwares, enabling robust decision-making while choosing technologies over trends and making mature decisions on a day-to-day development basis. This book is for all programming enthusiasts and is designed to be a Source code 101 level book, but it can help developers elevate to architect-level decision-making as well as architects to make solid software decisions while building the systems.
