What will you learn from this book?

Go makes it easy to build software that’s simple, reliable, and efficient. Andthis book makes it easy for programmers like you to get started. Googledesigned Go for high-performance networking and multiprocessing, but—like Python and JavaScript—the language is easy to read and use. With thispractical hands-on guide, you’ll learn how to write Go code using clearexamples that demonstrate the language in action. Best of all, you’ll understandthe conventions and techniques that employers want entry-level Godevelopers to know.

Why does this book look so different?

Based on the latest research in cognitive science and learning theory, HeadFirst Go uses a visually rich format to engage your mind rather than a textheavyapproach that puts you to sleep. Why waste your time struggling withnew concepts? This multisensory learning experience is designed for theway your brain really works.

About the author

Jay McGavren was doing automation for a hotel services company when a colleague introduced him to Programming Perl (a.k.a. the Camel Book). It made him an instant Perl convert, as he liked actually writing code instead of waiting for a 10-person development team to configure a build system. It also gave him the crazy idea to write a technical book someday.

In 2007, with Perl sputtering, Jay was looking for a new interpreted language. With its strong object-orientation, excellent library support, and incredible flexibility, Ruby immediately won him over. He's since used Ruby for two game libraries, a generative art project, in support of a Java development job, and as a Ruby on Railsfreelancer. He's been using Rails in the online developer education space since 2011.

Discover the fundamental concepts of object-relational mapping (ORM) design, Aurelius’ basic features, and the practical applications of those features. In a series of tasks, you will be exposed to techniques and best practices that make the use of Aurelius easy and efficient. Furthermore, you’ll refine your analytical skills to sharpen your understanding of Delphi (Pascal), helping you write better code along the way.
Introducing Delphi ORM explains that while database design is difficult, database programming (i.e., manipulating, extracting, filtering, and manipulating data) is even more difficult. ORM frameworks provide a simpler way for you to access and manage data in databases. You’ll see how they offer different levels of abstraction and tools to code data access in a database-agnostic way by introducing a layer between the application and the data access language (SQL, LINQ, and so on).
By the end of the book, you will be confident in using a wide range of Aurelius features to allow you to get started with databases in a very short space of time.

What You Will LearnGain the fundamentals of ORM frameworks and Aurelius for DelphiAchieve basic tasks, such as connecting to the database and adding, deleting, and updating records, using Aurelius Employ advanced database queries Use the TAureliusDataSet component Integrate with mobile platforms such as Android and iOSWork with the data modeler application
Who This Book Is For

75-80 recipes for learning Rust programmingAbout This BookLearn to build high-performance Rust units and integrate them into your existing applicationWork through recipes on performance, robustness, security, memory management, and scalabilityWork through recipes to build foreign function interface with C, JS, and PythonWho This Book Is For

If you want to write Rust programs, then this book is for you. This book is for those who have a basic knowledge of Rust or any programming language. If you are a C/C developer who is migrating to Rust for various reasons, this book is ideal for you.

What You Will LearnUnderstand system programming language problems and see how Rust provides unique solutionsGet to know the core concepts of Rust to develop fast and safe applicationsExplore the possibility of integrating Rust units into existing applications to make them more efficientAchieve better parallelism, security, and performanceExplore ways to package your Rust application and ship it for deployment in a production environmentDiscover how to build web applications and services using Rust to provide high-performance to the end userIn Detail

If you are building concurrent applications, server-side programs, or high-performance applications, you will benefit from this language. This book comes with a lot of application-specific recipes to kick-start your development of real-world high-performance applications with the Rust programming language and integrating Rust units into your existing applications. In this book, you will find some 80 practical recipes written in Rust that will allow you to use the code samples right away in your existing applications. These recipes have been tested with stable rust compiler versions of 1.14.0 and above.

This book will help you understand the core concepts of the Rust language, enabling you to develop efficient and high-performance applications by incorporating features such as zero cost abstraction and better memory management.

We'll delve into advanced-level concepts such as error handling, macros, crates, and parallelism in Rust. Toward the end of the book, you will learn how to create HTTP servers and web services, building a strong foundational knowledge in server-side programming and enabling you to deliver solutions to build high-performance and safer production-level web applications and services using Rust.

Style and approach

This book helps you learn the core concepts of Rust faster by taking a recipe-based approach, where you can try out different code snippets to understand a concept.

Stay motivated and overcome obstacles while learning to use Swift Playgrounds to be a great iOS developer. This book is perfect for those with no programming background, those with some programming experience but no object-oriented experience, or those that have a great idea for an app but haven’t programmed since school, and it is now updated for Swift 3.

Many people have a difficult time believing they can learn to write iOS apps. Swift 3 for Absolute Beginners, along with the free, live online training sessions will show you how to do so. You'll learn Object Oriented Programming and be introduced to HealthKit before moving on to write your own iPhone and Watch apps from scratch.

Gary Bennett and Brad Lees are full-time professional iOS developers and have developed a broad spectrum of apps for Fortune 500 companies. The authors have taken their combined 12 years of writing apps, teaching online iOS courses, the experience from their first three iOS books, along with their online instruction and free online forum at XcelMe.com to create an excellent training book.

What You’ll Learn:

· Work with Swift classes, properties, and functions

· Examine proper user interface and user experience design

· Understand Swift data types: integers, floats, strings, and booleans

· Use Swift data collections: arrays and dictionaries

· Review Boolean logic, comparing data, and flow control


Who This Book Is For

Anyone who wants to learn to develop apps for the Mac, iPhone, and iPad, and Watch using the Swift programming language. No previous programming experience is necessary.
