Python is currently used in many different areas such as software construction, systems administration, and data processing. In all of these areas, experienced professionals can find examples of inefficiency, problems, and other perils, as a result of bad code. After reading this book, readers will understand these problems, and more importantly, how to correct them. The book begins by describing the basic elements of writing clean code and how it plays an important role in Python programming. You will learn about writing efficient and readable code using the Python standard library and best practices for software design. You will learn to implement the SOLID principles in Python and use decorators to improve your code. The book delves more deeply into object oriented programming in Python and shows you how to use objects with descriptors and generators. It will also show you the design principles of software testing and how to resolve software problems by implementing design patterns in your code. In the final chapter we break down a monolithic application to a microservice one, starting from the code as the basis for a solid platform.

Clojure for Java Developers. Transition smoothly from Java to the most widely used functional JVM-based language – Clojure

Eduardo Díaz, Eduardo D Real

We have reached a point where machines are not getting much faster, software projects need to be delivered quickly, and high quality in software is more demanding as ever.We need to explore new ways of writing software that helps achieve those goals. Clojure offers a new possibility of writing high quality, multi-core software faster than ever, without having to leave your current platform.Clojure for Java developers aims at unleashing the true potential of the Clojure language to use it in your projects. The book begins with the installation and setup of the Clojure environment before moving on to explore the language in-depth. Get acquainted with its various features such as functional programming, concurrency, etc. with the help of example projects. Additionally, you will also, learn how the tooling works, and how it interacts with the Java environment. By the end of this book, you will have a firm grip on Clojure and its features, and use them effectively to write more robust programs.

Cloning Internet Applications with Ruby. Make clones of some of the best applications on the Web using the dynamic and object-oriented features of Ruby

Chang Sau Sheong

Most users on the Internet have a few favorite Internet web applications that they use often and cannot do without. These popular applications often provide essential services that we need even while we don’t fully understand its features or how they work. Ruby empowers you to develop your own clones of such applications without much ordeal. Learning how these sites work and describing how they can be implemented enables you to move to the next step of customizing them and enabling your own version of these services.This book shows the reader how to clone some of the Internet's most popular applications in Ruby by first identifying their main features, and then showing example Ruby code to replicate this functionality.While we understand that it connects us to our friends and people we want to meet up with, what is the common feature of a social network that makes it a social network? And how do these features work? This book is the answer to all these questions. It will provide a step-by-step explanation on how the application is designed and coded, and then how it is deployed to the Heroku cloud platform. This book’s main purpose is to break up popular Internet services such as TinyURL, Twitter, Flickr, and Facebook to understand what makes it tick. Then using Ruby, the book describes how a minimal set of features for these sites can be modeled, built, and deployed on the Internet.
