Effective AWK Programming, 5th Edition
When processing text files, the awk language is ideal for handling data extraction, reporting, and data-reformatting jobs. This practical guide serves as both a reference and tutorial for POSIX-standard awk and for the GNU implementation, called gawk. This book is useful for novices and awk experts alike.
In this thoroughly revised 5th edition, author and gawk lead developer Arnold Robbins describes the awk language and gawk program in detail, shows you how to use awk and gawk for problem solving, and then dives into specific features of gawk. System administrators, programmers, webmasters, and other power users will find everything they need to know about awk and gawk. ...
Learn Flutter, Google's multi-platform mobile development framework. Instantly view the changes you make to an app with stateful hot reload, and define a declarative UI in the same language as the app logic without having to use separate XML UI files. You can also reuse existing platform-specific Android and iOS code and interact with it in an efficient and simple way.
Use built-in UI elements - or build your own - to create a simple calculator app. Run native Java/Kotlin or Objective-C/Swift methods from your Flutter apps, and use a Flutter package to make HTTP requests to a Web API or to perform read and write operations on local storage. Apply visual effects to widgets, create transitions and animations, create a chat app using Firebase, and deploy everything on both platforms.
Get native look and feel and performance in your Android and iOS apps, and the ability to build for both platforms from a single code base. ...
Programming Machine Learning
Peel away the obscurities of machine learning, starting from scratch and going all the way to deep learning. Machine learning can be intimidating, with its reliance on math and algorithms that most programmers don't encounter in their regular work. Take a hands-on approach, writing the Python code yourself, without any libraries to obscure what's really going on. Iterate on your design, and add layers of complexity as you go.
Build an image recognition application from scratch with supervised learning. Predict the future with linear regression. Dive into gradient descent, a fundamental algorithm that drives most of machine learning. Create perceptrons to classify data. Build neural networks to tackle more complex and sophisticated data sets. Train and refine those networks with backpropagation and batching. Layer the neural networks, eliminate overfitting, and add convolution to transform your neural network into a true deep learning system.
Start from the beginning and code your ...
Modern Systems Programming with Scala Native
Access the power of bare-metal systems programming with Scala Native, an ahead-of-time Scala compiler. Without the baggage of legacy frameworks and virtual machines, Scala Native lets you re-imagine how your programs interact with your operating system. Compile Scala code down to native machine instructions; seamlessly invoke operating system APIs for low-level networking and IO; control pointers, arrays, and other memory management techniques for extreme performance; and enjoy instant start-up times. Skip the JVM and improve your code performance by getting close to the metal.
Developers generally build systems on top of the work of those who came before, accumulating layer upon layer of abstraction. Scala Native provides a rare opportunity to remove layers. Without the JVM, Scala Native uses POSIX and ANSI C APIs to build concise, expressive programs that run unusually close to bare metal. Scala Native compiles Scala code down to native machine instructions instead of JVM b ...
Programming with 64-Bit ARM Assembly Language
Mastering ARM hardware architecture opens a world of programming for nearly all phones and tablets including the iPhone/iPad and most Android phones.

Beginning Ring Programming
Gain a gentle introduction to the world of Ring programming with clarity as a first concern using a lot of practical examples. The first part lays the foundations of the language and its basic features (data types, control structures, functions, and classes). The unique way to rigorously structure Ring programs is also explained.
Then, in the second part you'll discover Ring inputs, outputs, and what is in between. You'll use the basic constructs of computer logic (sequence, selection, and iteration) to build simple and complex logic flows. You'll go over the common mistakes that lead to code complexity, by example, and cover several strategies to solve them (refactoring, code cleansing, and good variable naming). Then, you'll see a visual illustration of how Ring deals with scopes at the local, object, and global levels.
In part three, you'll play with two artifacts vital to Ring programming: functions and objects. You'll learn how they can be composed to solve a problem ...
