Build Your Own Programming Language. A programmer's guide to designing compilers, interpreters, and DSLs for solving modern computing problems

Clinton L. Jeffery

The need for different types of computer languages is growing rapidly and developers prefer creating domain-specific languages for solving specific application domain problems. Building your own programming language has its advantages. It can be your antidote to the ever-increasing size and complexity of software.In this book, you’ll start with implementing the frontend of a compiler for your language, including a lexical analyzer and parser. The book covers a series of traversals of syntax trees, culminating with code generation for a bytecode virtual machine. Moving ahead, you’ll learn how domain-specific language features are often best represented by operators and functions that are built into the language, rather than library functions. We’ll conclude with how to implement garbage collection, including reference counting and mark-and-sweep garbage collection. Throughout the book, Dr. Jeffery weaves in his experience of building the Unicon programming language to give better context to the concepts where relevant examples are provided in both Unicon and Java so that you can follow the code of your choice of either a very high-level language with advanced features, or a mainstream language.By the end of this book, you’ll be able to build and deploy your own domain-specific languages, capable of compiling and running programs.

Driving Data Quality with Data Contracts. A comprehensive guide to building reliable, trusted, and effective data platforms

Andrew Jones, Kevin Hu

Despite the passage of time and the evolution of technology and architecture, the challenges we face in building data platforms persist. Our data often remains unreliable, lacks trust, and fails to deliver the promised value.With Driving Data Quality with Data Contracts, you’ll discover the potential of data contracts to transform how you build your data platforms, finally overcoming these enduring problems. You’ll learn how establishing contracts as the interface allows you to explicitly assign responsibility and accountability of the data to those who know it best—the data generators—and give them the autonomy to generate and manage data as required. The book will show you how data contracts ensure that consumers get quality data with clearly defined expectations, enabling them to build on that data with confidence to deliver valuable analytics, performant ML models, and trusted data-driven products.By the end of this book, you’ll have gained a comprehensive understanding of how data contracts can revolutionize your organization’s data culture and provide a competitive advantage by unlocking the real value within your data.

ASP.NET MVC 4 Mobile App Development. If your skill-sets include developing in C# on the .NET platform, this tutorial is a golden opportunity to extend your capabilities into mobile app development using the ASP.NET MVC framework. A totally practical primer

Andrew Scott Meadows, Andy Meadows

The ASP.NET MVC 4 framework is used to build scalable web applications with the help of design patterns and .NET Framework. The Model-View-Controller (MVC) is a design principle which separates the components of a web application. This separation helps you to modify, develop, and test different components of a web application.ASP.NET MVC 4 Mobile App Development helps you to develop next generation applications, while guiding you to deal with the constraints the mobile web places on application development. By the end of the book, you will be well versed with all the aspects of mobile app development.ASP.NET MVC 4 Mobile App Development introduces you to developing mobile web apps using the ASP.NET MVC 4 framework. Walking you through the process of creating a homebrew recipe sharing application, this book teaches you the fundamentals and concepts relevant to developing Internet-ready mobile-enabled web apps. Through the sample application, you will learn how to secure your apps against XSS and CSRF attacks, open up your application to users using third party logins such as Google or Facebook, and how to use Razor, HTML 5, and CSS 3 to create custom views and content targeting mobile devices. Using these custom views, you will then learn how to create web apps with a native mobile device feel using jQuery mobile. By the end of the book, you will be presented with a set of challenges to prove to yourself that you now have the skills to extend your existing web applications to the mobile web or create new mobile web apps.

Mastering .NET Machine Learning. Use machine learning in your .NET applications

Jamie Dixon

.Net is one of the widely used platforms for developing applications. With the meteoric rise of Machine learning, developers are now keen on finding out how can they make their .Net applications smarter. Also, .NET developers are interested into moving into the world of devices and how to apply machine learning techniques to, well, machines.This book is packed with real-world examples to easily use machine learning techniques in your business applications. You will begin with introduction to F# and prepare yourselves for machine learning using .NET framework. You will be writing a simple linear regression model using an example which predicts sales of a product. Forming a base with the regression model, you will start using machine learning libraries available in .NET framework such as Math.NET, Numl.NET and Accord.NET with the help of a sample application. You will then move on to writing multiple linear regressions and logistic regressions.You will learn what is open data and the awesomeness of type providers. Next, you are going to address some of the issues that we have been glossing over so far and take a deep dive into obtaining, cleaning, and organizing our data. You will compare the utility of building a KNN and Naive Bayes model to achieve best possible results.Implementation of Kmeans and PCA using Accord.NET and Numl.NET libraries is covered with the help of an example application. We will then look at many of issues confronting creating real-world machine learning models like overfitting and how to combat them using confusion matrixes, scaling, normalization, and feature selection. You will now enter into the world of Neural Networks and move your line of business application to a hybrid scientific application. After you have covered all the above machine learning models, you will see how to deal with very large datasets using MBrace and how to deploy machine learning models to Internet of Thing (IoT) devices so that the machine can learn and adapt on the fly.
