The Definitive Guide to JSF in Java EE 8
Learn and master the new features in the JSF 2.3 MVC web framework in this definitive guide written by two of the JavaServer Faces (JSF) specification leads. The authors take you through real-world examples that demonstrate how these new features are used with other APIs in Java EE 8. You'll see the new and exciting ways JSF applications can use to communicate between a client and a server, such as using WebSockets, invoking bean methods directly from Ajax, executing client-side JavaScript when Ajax calls complete, and more. Along the way you'll broaden your knowledge of JSF components and web APIs best practices, and learn a great deal about the internals of JSF and the design decisions that have been made when building the JSF API. For example, you'll see what artefacts are now CDI injectable, how CDI changed JSF internally, and what some of the caveats are when working with the CDI versions of a JSF artefact. Furthermore, you'll build an example application from scratch. After r ...

Hands-On MQTT Programming with Python
MQTT is a lightweight messaging protocol for small sensors and mobile devices. This book explores the features of the latest versions of MQTT for IoT and M2M communications, how to use them with Python 3, and allow you to interact with sensors and actuators using Python. The book begins with the specific vocabulary of MQTT and its working modes, followed by installing a Mosquitto MQTT broker. You will use different utilities and diagrams to understand the most important concepts related to MQTT. You will learn to make all the necessary configuration to work with digital certificates for encrypting all data sent between the MQTT clients and the server. You will also work with the different Quality of Service levels and later analyze and compare their overheads. You will write Python 3.x code to control a vehicle with MQTT messages delivered through encrypted connections (TLS 1.2), and learn how leverage your knowledge of the MQTT protocol to build a solution based on requirements. ...

Sales Hunting
The first year of developing a new sales territory is a daunting task—especially in dog-eat-dog industries. The traditional advice is to train quickly on product, grab a customer list, start calling for appointments, discover opportunities, and close deals. In fact, almost every sales model out there is based on nothing more than "opportunity" management. But jumping straight to opportunity will have new salespeople—or veterans developing new territories—chasing their tails for the first year or two. As Sales Hunting: How to Develop New Territories and Major Accounts in Half the Time Using Trust as Your Weapon details, there is a significant problem you must overcome when opening up new accounts and territories. No matter what you are selling, your prospect already has a trusted relationship with an incumbent vendor and will continue to buy from that vendor even when you have the better solution. ...

Hands-On Microservices with Node.js
Microservices enable us to develop software in small pieces that work together but can be developed separately; this is one reason why enterprises have started embracing them. For the past few years, Node.js has emerged as a strong candidate for developing microservices because of its ability to increase your productivity and the performance of your applications. Hands-On Microservices with Node.js is an end-to-end guide on how to dismantle your monolithic application and embrace the microservice architecture - right from architecting your services and modeling them to integrating them into your application. We'll develop and deploy these microservices using Docker. Scalability is an important factor to consider when adding more functionality to your application, and so we delve into various solutions, such as Docker Swarm and Kubernetes, to scale our microservices. Testing and deploying these services while scaling is a real challenge; we'll overcome this challenge by setting up de ...
