Mastering Kotlin. Learn advanced Kotlin programming techniques to build apps for Android, iOS, and the web

Nate Ebel

Using Kotlin without taking advantage of its power and interoperability is like owning a sports car and never taking it out of the garage. While documentation and introductory resources can help you learn the basics of Kotlin, the fact that it’s a new language means that there are limited learning resources and code bases available in comparison to Java and other established languages.This Kotlin book will show you how to leverage software designs and concepts that have made Java the most dominant enterprise programming language. You’ll understand how Kotlin is a modern approach to object-oriented programming (OOP). This book will take you through the vast array of features that Kotlin provides over other languages. These features include seamless interoperability with Java, efficient syntax, built-in functional programming constructs, and support for creating your own DSL. Finally, you will gain an understanding of implementing practical design patterns and best practices to help you master the Kotlin language.By the end of the book, you'll have obtained an advanced understanding of Kotlin in order to be able to build production-grade applications.

Generative AI with LangChain. Build large language model (LLM) apps with Python, ChatGPT, and other LLMs

Ben Auffarth

Blender 3D 2.49 Incredible Machines

Allan Brito, Ton Roosendaal

Blender 3D provides all the features you need to create super-realistic 3D models of machines for use in artwork, movies, and computer games. Blender 3D 2.49 Incredible Machines gives you step-by-step instructions for building weapons, vehicles, robots, and more.This book will show you how to use Blender 3D for mechanical modeling and product visualization. Through the pages of the book, you will find a step-by-step guide to create three different projects: a fantasy weapon, a spacecraft, and a giant robot. Even though these machines are not realistic, you will be able to build your own sensible and incredible machines with the techniques that you will learn in this book along with the exercises and examples.All the three sections of this book, which cover three projects, are planned to have an increasing learning curve. The first project is about a hand weapon, and with that we can image a small-sized object with tiny details. This first part of the book will show you how to deal with these details and model them in Blender 3D.In the second project, we will create a spacecraft, adding a bit of scale to the project, and new materials and textures as well. With this project, we will be working with metal, glass, and other elements that make the spacecraft. Along with the object, a new space environment will be created in the book too.At the end we have a big and complex object, which is the transforming robot. This last part of the book will cover the modeling of two objects and show how you can make one transform into the other. The scale and number of objects in this project are quite big, but the same principles as in the other projects are applied here with a step-by-step guide on how to go through the workflow of the project.
