Build a maintainable Rails application by using next-generation gems from the dry-rb and rom-rb suite. This book shows you how to easily bring those gems into the web framework you know and... well, the one you know. Learn how to build a maintainable Rails application by using the rom-rb and dry-rb set of gems to your advantage. Move away from messy, traditional Rails code and move towards crisp, clean code. The default structure of Rails applications hasn't changed all that much in over a decade. And with good reason: this directory structure makes it easy to jump into building a Rails application. While I agree that this way is still extremely simple and great for getting started within a Rails application, I do not agree that this is the best way to organise a Rails application with long-term maintenance in mind. A decade of Ruby development has produced some great alternatives to Rails' MVC directory structure that are definitely worthwhile to consider.

This book will teach you super neat tricks about Ruby, Rails and PostgreSQL while you build a multi-tenanted, Software as a Service, Ruby on Rails application. This book is a book that will teach you about building a multi-tenant Ruby on Rails application. Hopefully you knew that already. This particular kind of application is usually referred to as a “Software as a Service” (or SaaS for short) application, as it’s a piece of software which is providing a service to a group of people. The application we’ll be building in this book isn’t based off an original, outlandish idea, but a rather simple one: hosted blogs. This is a similar idea to Tumblr, or other blogging platforms. For a user to be able to create their own posts, they can sign up to our application for an account (Chapter 2), which would be sandboxed from the other accounts on the system (Chapter 3). Once they’re done with that, they will then be able to create posts for their blog (Chapter 4). In the later chapters, we cover things such as monthly subscriptions and billing for them (Chapter 5). That’s a quick overview of what you’ll be learning in this book as a whole. At the end of it, you will know how you can build a multi-tenanted Software as a Service Rails application.

The Toy Robot is a common interview exercise for new programmers. This short book will take you through how to implement it in Elixir in a BDD-style, with some great explanations and imagery along the way. The Toy Robot exercise was originally developed by Jon Eaves. He explains why he did it in this blog post. If you're a new Elixir developer who's gone through some basic Elixir tutorials and you're looking for the next thing to build your skills, this book is a great start. It covers the Toy Robot exercise from start to finish, testing with Elixir features such as ExUnit and Doctests along the way. The Toy Robot exercise is commonly used in interviews as the ways to solve it in any language are not as simple as they first may seem. This book covers one implementation of this exercise in Elixir. It is not intended to be the most perfect implementation of the Toy Robot exercise possible, but instead is my personal take on it.

This book is a crosswalk from traditional code to visual scripting. This book is about reconstructing traditional and widely used design patterns in a visual scripting environment. The visual scripting environment is Unreal Engine’s “Blueprints.” We will discuss and implement design patterns to solve some of the most common problems in programming. You will not need to read much of the background material on the design patterns if you are an experienced coder. Chances are, you probably have used many of these patterns previously. Do not fret If you are not a coder. If you are familiar with Blueprints, then you can, and should implement design patterns into your workflow when necessary. C++, Java, and C# “equivalent” code is provided for each design pattern discussed. Additionally, there is an accompanying UML diagram for each design pattern of the Java code implementation. We follow the code in blueprints as close as possible. Some of you may be thinking, “Hey, why would you use Java and C# when Unreal’s main coding language is C++.” I have nothing against C++. I chose to add Java and C# for a few reasons.

Python is a high-level, structured and general-purpose functional programming language that emphasizes on readability of text. Python syntax helps programmers code in less phases relative to Java or C++. Python has diversified uses in software technology companies such as games, online platforms and apps, language creation, prototyping, visual design uses, etc. It makes the language a greater abundance than many programming languages employed in the business. Python is a versatile programming language that makes efficient usage of code lines, installation can be performed in a fantastic way, and debugging can be achieved easily. This has been particularly relevant around the globe because Google company has declared it one of the main programming languages. We've seen a user-friendly and concise solution to Python. Python is the youngest of all the languages but it also gives a lot of frameworks. Python is a strong language all over, but it only excels with the ability to bring a lot of features with only a little bit of coding.

React is a jаvascript library developed internally at Facebook and open sourced in 2013 for building interactive user interfaces for the web. It introduces a new way to deal with the Browser’s DOM. Gone are the days of manually updating the DOM and laboriously keeping track of each piece of state that makes scalability and new feature development at best, a risky endeavor. Instead, React deals with the DOM in a very novel way. You declaratively define your user interface at any point in time. React removes the need to worry about which part of the DOM needs to update when data changes, and enables you to essentially re-render your entire application at any point in time with minimal DOM changes. To get the most out of this book you’ll need to be experienced with jаvascript and HTML. It’s beneficial if you have experience with writing SPAs (regardless of which framework like Backbone.js, AngularJS, or Ember.js), but it is not required.

The official C++ Core Guidelines provide consistent best practices for writing outstanding modern C++ code, but they aren't organized for easy usage by working developers. In C++ Core Guidelines Explained, expert C++ instructor Rainer Grimm has distilled them to their essence, removing esoterica, sharing new insights and context, and presenting well-tested examples from his own training courses. C++ is, in particular for beginners, an inherently complex language. Mainly, because the problems we want to solve are inherently complicated and often complex as well. When you teach C++, you should provide a set of rules that work for your participants in at least 95% of all use-cases.
