Django is a web framework that was designed to strike a balance between rapid web development and high performance. It has the capacity to handle applications with high levels of user traffic and interaction, and can integrate with massive databases on the backend, constantly collecting and processing data in real time.Through this book, you'll discover that collecting data from different sources and providing it to others in different formats isn't as difficult as you thought. It follows a task-based approach to guide you through all the web development processes using the Django framework. We’ll start by setting up the virtual environment for a Django project and configuring it. Then you’ll learn to write reusable pieces of code for your models and find out how to manage database schema changes using South migrations. After that, we’ll take you through working with forms and views to enter and list data. With practical examples on using templates and JavaScript together, you will discover how to create the best user experience. In the final chapters, you'll be introduced to some programming and debugging tricks and finally, you will be shown how to test and deploy the project to a remote dedicated server.By the end of this book, you will have a good understanding of the new features added to Django 1.8 and be an expert at web development processes.

Windows Azure Platforma Cloud Computing dla programistów
Praca zbiorowa
Chmura obliczeniowa (Cloud Computing) jest kolejnym milowym krokiem w rozwoju informatyki. Ujmując rzecz najogólniej, można powiedzieć, że w odróżnieniu od dostarczania oprogramowania cloud computing jest metodą dostarczania, opartych na oprogramowaniu, serwisów i usług. Możliwości, jakie zapewnia, obejmują zarówno rozwiązania dla użytkowników indywidualnych, jak i przedsiębiorstw. Najlepiej znaną definicję Chmury opracowali analitycy Gartnera: „Cloud computing to styl obliczeń, w którym dynamicznie skalowalne (zwykle zwirtualizowane) zasoby są dostarczane jako usługa za pośrednictwem Internetu. Użytkownik nie musi mieć wiedzy na temat tego, w jaki sposób ta usługa jest realizowana, nie musi też zajmować się aspektami technicznymi niezbędnymi do jej działania”. Cloud computing bazuje na koncepcji tworzenia rozproszonych systemów obliczeniowych, zlokalizowanych w różnych centrach danych na całym świecie i dostępnych za pomocą interfejsów sieciowych. Ze strony Microsoft takim rozwiązaniem dla rynku jest Windows Azure. Książka „Windows Azure Platforma Cloud Computing dla programistów” to pierwsza w Polsce tak obszerna pozycja opisująca zagadnienia Cloud Computing dla programistów. Ambicją autorów było stworzenie kompendium wiedzy dla programistów .NET, PHP i Javy, którzy w łatwy sposób mogą tworzyć skalowalne rozwiązania w oparciu o Windows Azure.

This book introduces readers to three powerful command-line utilities—grep, sed, and awk—that can create simple yet powerful shell scripts. Using the bash shell, it focuses on small text files to help readers understand these tools. Grep searches for patterns in data, sed modifies data, and awk performs tasks on pattern matches. Aimed at those new to the bash environment, the book is also valuable for those with some experience.The journey starts with grep, teaching how to search for specific words or patterns in data. It then moves to sed, showing how to change or modify data efficiently. Finally, it delves into awk, a versatile programming language for searching and processing data files. The book also includes a chapter on using regular expressions with these tools, enhancing your scripting capabilities.Mastering these utilities is crucial for efficient data handling and automation in a bash environment. This book transitions readers from basic to advanced command-line skills, blending theory with practical examples. It is an essential resource for anyone looking to harness the full power of bash scripting.
