A Practical Introduction to Python Programming
This book started out as about 30 pages of notes for students in my introductory programming class at Mount St. Mary's University. Most of these students have no prior programming experience, and that has affected my approach. I leave out a lot of technical details and sometimes I oversimplify things. Some of these details are filled in later in the book, though other details are never filled in. But this book is not designed to cover everything, and I recommend reading other books and the Python documentation to fill in the gaps. The style of programming in this book is geared towards the kinds of programming things I like to do - short programs, often of a mathematical nature, small utilities to make my life easier, and small computer games. In fact, the things I cover in the book are the things that I have found most useful or interesting in my programming experience, and this book serves partly to document those things for myself.

How To Build a Website With CSS and HTML
This project-based eBook will introduce you to Cascading Style Sheets (CSS), a stylesheet language used to control the presentation of websites, by building a personal website using our demonstration site as a model. Though our demonstration site features Sammy the Shark, you can switch out Sammy's information with your own if you wish to personalize your site. Alongside HTML and JavaScript, CSS is one of the core technologies of the World Wide Web. If you have some understanding of HTML and are looking to grow your front-end development skills, learning CSS is a great next step. The first half of this book will introduce CSS through hands-on exercises and the second half of the tutorial series will provide steps for recreating the demonstration website. By the end of this CSS book, you will have files ready for deploying a website to the cloud, as well as an understanding of how to continue modifying the site's design with HTML and CSS. You will also have a foundation for lea ...

iOS Unit Testing by Example
Fearlessly change the design of your iOS code with solid unit tests. Use Xcode's built-in test framework XCTest and Swift to get rapid feedback on all your code - including legacy code. Learn the tricks and techniques of testing all iOS code, especially view controllers (UIViewControllers), which are critical to iOS apps. Learn to isolate and replace dependencies in legacy code written without tests. Practice safe refactoring that makes these tests possible, and watch all your changes get verified quickly and automatically. Make even the boldest code changes with complete confidence. Manual code and UI testing get slower the deeper your navigation hierarchy goes. It can take several taps just to reach a particular screen, never mind the actual workflow tests. Automatic unit testing offers such rapid feedback that it can change the rules of development. Bring testing to iOS development, even for legacy code. Use XCTest to write unit tests in Swift for all your code. iOS developers ...

Explore Software Defined Radio
Do you want to be able to receive satellite images using nothing but your computer, an old TV antenna, and a $20 USB stick? Now you can. At last, the technology exists to turn your computer into a super radio receiver, capable of tuning in to FM, shortwave, amateur "ham," and even satellite frequencies, around the world and above it. Listen to police, fire, and aircraft signals, both in the clear and encoded. And with the book's advanced antenna design, there's no limit to the signals you can receive. Combine your desktop or laptop computer with easy-to-find Software Defined Radio (SDR) equipment, and tune in a wide range of signals in no time at all. Then, go one step further by converting a Raspberry Pi into your own dedicated SDR device. SDR USB dongles are usually designed to receive and decode high-definition digital television broadcasts, but the rising popularity of SDR has led to several of these devices being specifically made for - and marketed to - the software radio ...

The Common Java Cookbook
This book focuses on tactical implementation details, answering such questions as: How do we parse XML? How do we serialize beans? Is there an easier way to work with Collections? How do we work with HTTP and keep track of cookies? In enterprise software development, the tactical is often sacrificed for the strategic. Consider a complex enterprise-scale system with a solid, well-conceived architecture. The strategic (or high-level) design appears reasonable from 40,000 feet, but as soon as you drill into the details, you notice that every component contains pages upon pages of unmaintainable and unnecessary code because the developers were not aware of some valuable time-saver like BeanUtils, Collections, or the Digester. Or, worse, the developer may have spent a week reimplementing most of the capabilities of Commons BeanUtils even though BeanUtils was already in the classpath. While a familiarity with Apache Commons may not directly affect the architecture of your application, knowin ...

Beginning Machine Learning in the Browser
Apply Artificial Intelligence techniques in the browser or on resource constrained computing devices. Machine learning (ML) can be an intimidating subject until you know the essentials and for what applications it works. This book takes advantage of the intricacies of the ML processes by using a simple, flexible and portable programming language such as JavaScript to work with more approachable, fundamental coding ideas. Using JavaScript programming features along with standard libraries, you'll first learn to design and develop interactive graphics applications. Then move further into neural systems and human pose estimation strategies. For training and deploying your ML models in the browser, TensorFlow.js libraries will be emphasized. After conquering the fundamentals, you'll dig into the wilderness of ML. Employ the ML and Processing (P5) libraries for Human Gait analysis.
