Book Description

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.

Book Description

Object Oriented Programming is a very important aspect of modern programming languages. The basic principles of Object Oriented Programming are relatively easy to learn. Putting them together into working designs can be challenging.

This book makes programming more of a pleasure than a chore using powerful Python 3 object-oriented features of Python 3. It clearly demonstrates the core OOP principles and how to correctly implement OOP in Python.

Object Oriented Programming ranks high in importance among the many models Python supports. Yet, many programmers never bother learning the powerful features that make this language object oriented.

The book teaches when and how OOP should be correctly applied. It emphasizes not only the simple syntax of OOP in Python, but also how to combine these objects into well-designed software.

This book will introduce you to the terminology of the object-oriented paradigm, focusing on object-oriented design with step-by-step examples. It will take you from simple inheritance, one of the most useful tools in the object-oriented programmer’s toolbox, all the way through to cooperative inheritance, one of the most complicated. You will be able to raise, handle, define, and manipulate exceptions.

You will be able to integrate the object-oriented and the not-so-object-oriented aspects of Python. You will also be able to create maintainable applications by studying higher level design patterns. You’ll learn the complexities of string and file manipulation, and how Python distinguishes between binary and textual data. Not one, but two very powerful automated testing systems will be introduced to you. You’ll understand the joy of unit testing and just how easy they are to create. You’ll even study higher level libraries such as database connectors and GUI toolkits and how they apply object-oriented principles.

Book Description

As time goes on, system administrators are presented with increasingly complicated challenges. In the early days, a team of engineers might have had to look after one or two systems. These days, one engineer can administer hundreds or thousands of systems.

System administrators are gradually replacing their tools with more advanced and flexible ones. One of the choices is Python. Structurally, Python is a modern, high-level language with a very clean syntax. Python comes with many built-in libraries that can make automation tasks easier. It also has extensive set of third-party libraries and a very active development community. This flexibility makes Python a good choice for a wide variety of tasks, from prototyping science applications to system maintenance and administration jobs.

• This book explains and shows how to apply Python scripting in practice. Unlike the majority of the Python books, it will show you how to approach and resolve real-world issues that most system administrators will come across in their careers.
• In this book, you will find several projects in the categories of network administration, web server administration, and monitoring and database management. In each project, we will define the problem, design the solution, and go through the more interesting implementation steps.
• Each project is accompanied with the source code of a fully working prototype, which you’ll be able to use immediately or adapt to your requirements and environment.

Book Description

Spring Python captures the concepts of the Spring Framework and Spring Security and brings them to the world of Python and provides many functional parts to assemble applications. Spring Python is all about using the many useful features of Spring to the fullest and making these features available when working with Python.

Get to grips with all of the concepts of Spring and apply these to the language and environment of Python to develop powerful applications for your own personal requirements. The book provides an introduction to Spring Python and steadily takes you towards the advanced features that this integration has to offer.

Spring uses the Java programming language. Spring Python, the first Spring extension to go live, allows developers to make maximum use of Spring features in Python. This book starts off by introducing each of the core building blocks of Spring Python using real code examples and high-level diagrams. It explores the various concepts of Spring Python with the help of examples and case studies and focuses on vital Spring Python features to make the lives of Python and Java developers simple. The early chapters cover simple applications with simple operations including data access, and then subsequent chapters scale up to multi-node, secured, transactional applications stopping short of very advanced level complexity.

This book will help you to scale your applications without having to add unnecessary complexity Download Now »

Book Description

Django is a high-level Python web framework that was developed by a fast-moving online-news operation to meet the stringent twin challenges of newsroom deadlines and the needs of web developers. It provides an excellent basis to build e-commerce websites because it can be deployed fast and it responds quickly to changes due to its ability to handle content problems. Django with its proven strengths is all you need to build powerful e-commerce applications with a competitive edge.

This book explores how the Django web framework and its related technologies can power the next leap forward for e-commerce and business on the Web. It shows you how to build real-world applications using this rapid and powerful development tool.
