Delphi Cookbook - Third Edition

By: Spinetti, Daniele Teti

Overview of this book

Delphi is a cross-platform integrated development environment (IDE) that supports rapid application development on different platforms, saving you the pain of wandering amid GUI widget details or having to tackle inter-platform incompatibilities. Delphi Cookbook begins with the basics of Delphi and gets you acquainted with JSON format strings, XSLT transformations, Unicode encodings, and various types of streams. You’ll then move on to more advanced topics such as developing higher-order functions and using enumerators and run-time type information (RTTI). As you make your way through the chapters, you’ll understand Delphi RTL functions, use FireMonkey in a VCL application, and cover topics such as multithreading, using aparallel programming library and deploying Delphi on a server. You’ll take a look at the new feature of WebBroker Apache modules, join the mobile revolution with FireMonkey, and learn to build data-driven mobile user interfaces using the FireDAC database access framework. This book will also show you how to integrate your apps with Internet of Things (IoT). By the end of the book, you will have become proficient in Delphi by exploring its different aspects such as building cross-platforms and mobile applications, designing server-side programs, and integrating these programs with IoT.

How to build a modern Linux daemon

Each Linux system has a bunch of processes running. Some processes have the goal to run for a long time on the system in the background: daemons. A daemon (or service) is a particular type of process that runs in the background and is designed to run autonomously, with little or no user intervention.

Many programs use daemons to solve current scenarios: a web server to provide static content for web pages, email service like SMTP, and so on.

You must use a specific set of rules in a given order to create a daemon in Linux. To understand how daemons works in Linux, we have to see them in action. They give you incredible flexibility and power, and for this reason they are one of the fundamental building blocks in Linux.
