Drupal 7 Social Networking. Build a social or community website with friends lists, groups, custom user profiles, and much more

MICHAEL KEITH PEACOCK

Drupal is ideally equipped to serve as a base system for creating a custom social networking site like Facebook or MySpace. While these large social networks have their place, niche social networking websites can help promote businesses, products, projects, and hobbies of any nature.Drupal 7 Social Networking provides careful instructions and clear explanations to take you through the setup and management of your social network site, covering topics from users, to marketing, to maintenance. It will help you create your own social networking site, suitable for whatever audience you choose!Starting from the very basics of both Drupal and Social Networking, right through to more complicated aspects, you will progressively learn how to add to and expand your social networking site and add more features. You will learn how to secure your social network, deploy it on the Internet, and keep it running and well maintained. As social networking sites rely on the participation of their users, this book helps you to structure your site in such a way so that users can easily and enjoyably contribute, thus creating a powerful social network.

Robert Varkonyi

Rules is what every Drupal site builder and developer has to use when creating event ñ action-based applications. The framework provides a highly flexible way to create sophisticated, condition-based functions any Drupal based system into an interactive application. Rules makes Drupal rule the CMS world.Drupal Rules How-to is a practical, hands-on guide that provides you with a number of clear step-by-step exercises, which will help you take advantage of the real power of the Rules framework, and understand how to use it on a site builder and developer levelThis book demonstrates the power and flexibility of the Rules framework. It discusses the main aspects of the module both from the site builder and developer perspective, from basic and advanced Rule configurations using Events, Conditions, Actions and Components to getting familiar with the Rules API. You will also learn how to use additional modules together with Rules to further extend the possibilities of your Drupal system, such as Rules Scheduler to schedule the execution of your Rule configurations and Views Bulk Operations to execute Rule configurations on a view result list. The book also demonstrates the main API features that enable you to create your own Events, Conditions and Actions, provide new data types to Rules and execute your configurations programmatically

Edge Computing Simplified. Explore all aspects of edge computing for business leaders and technologists

Perry Lea

The migration of computing to the edge is the logical progression of where computing is performed on a global scale. Edge computing is not a new paradigm but a necessary technology to address issues such as latency, service charges, reliability, connectivity, and privacy. This book walks you through the definition and architecture of edge computing systems and why they are critical in today’s ecosystem of IoT devices and an “everything connected” world.You will start your journey with an introduction to different edge computing hardware platforms, which vary by use case. From there, you’ll explore operating systems and middleware packages that manage edge devices such as Azure IoT. Then, you will explore communication systems such as near-range Bluetooth and RFID as well as long-range systems such as 5G. Networking protocols will be covered, which are the heart of edge systems. Technologies such as MQTT, which make up the backbone of edge to cloud communication, are examined. Then, you will move on to edge applications such as edge predictive AI and federated computing. We wrap up by investigating the security and vulnerability envelope of edge systems.This book is intended to quickly familiarize you with edge systems technologies and use cases, without burdening you with complicated jargon and low-level details.

Edge Computing Systems with Kubernetes. A use case guide for building edge systems using K3s, k3OS, and open source cloud native technologies

Sergio Mendez

Edge computing is a way of processing information near the source of data instead of processing it on data centers in the cloud. In this way, edge computing can reduce latency when data is processed, improving the user experience on real-time data visualization for your applications. Using K3s, a light-weight Kubernetes and k3OS, a K3s-based Linux distribution along with other open source cloud native technologies, you can build reliable edge computing systems without spending a lot of money.In this book, you will learn how to design edge computing systems with containers and edge devices using sensors, GPS modules, WiFi, LoRa communication and so on. You will also get to grips with different use cases and examples covered in this book, how to solve common use cases for edge computing such as updating your applications using GitOps, reading data from sensors and storing it on SQL and NoSQL databases. Later chapters will show you how to connect hardware to your edge clusters, predict using machine learning, and analyze images with computer vision. All the examples and use cases in this book are designed to run on devices using 64-bit ARM processors, using Raspberry Pi devices as an example.By the end of this book, you will be able to use the content of these chapters as small pieces to create your own edge computing system.

EJB 3.0 Database Persistence with Oracle Fusion Middleware 11g. This book walks you through the practical usage of EJB 3.0 database persistence with Oracle Fusion Middleware. Lots of examples and a step-by-step approach make it a great way for EJB application developers to acquire new skills

Deepak Vohra

EJB (Enterprise JavaBeans) 3.0 is a commonly used database persistence technology in Java EE applications. EJB 3.0 has simplified the development of EJBs with an annotations-based API that eliminates the use of remote/local interfaces, home/local home interfaces, and deployment descriptors. A number of other books are available on EJB 3.0, but none covers EJB 3.0 support in Oracle Fusion Middleware 11g, which is one of the leaders in the application server market.This is the first book that covers all aspects of EJB 3.0 database persistence development using Oracle Fusion Middleware technology. It covers all the best practices for database persistence ensuring that your applications are easily maintainable. Leaving theory behind, this book uses real-world examples to guide you in building your own EJB 3.0 applications that are well integrated with commonly used Java EE frameworks.The book gets going by discussing the new features in the EJB 3.0 specification. As some readers may still be using EJB 2.0, the book explains how to convert your EJB 2.0 entity beans to EJB 3.0. It then goes on to discuss using EJB 3.0 database persistence with JDeveloper, WebLogic Server, and Enterprise Pack for Eclipse, the main Java EE components of Oracle Fusion Middleware 11g. The book also covers EJB 3.0 relationships and integrating EJB 3.0 relationships with JSF user interfaces. EJB 3.0 database persistence with some of the commonly used frameworks such as ADF Faces, AJAX, and Web Services is also discussed in the book. It uses the integrated WebLogic Server 11g in some of the chapters and the standalone WebLogic Server in other chapters. While JDeveloper is the primary Java IDE used in the book, one of the chapters is based on the Oracle Enterprise Pack for Eclipse.By the time you reach the end of this book, you will be well-versed with developing EJB 3.0 applications using the different Java EE components of Oracle Fusion Middleware 11g.
