Book Description

Learn how to develop your own applications to monitor or control instrumentation hardware. Whether you need to acquire data from a device or automate its functions, this practical book shows you how to use Python’s rapid development capabilities to build interfaces that include everything from software to wiring. You get step-by-step instructions, clear examples, and hands-on tips for interfacing a PC to a variety of devices.

Use the book’s hardware survey to identify the interface type for your particular device, and then follow detailed examples to develop an interface with Python and C. Organized by interface type, data processing activities, and user interface implementations, this book is for anyone who works with instrumentation, robotics, data acquisition, or process control.

• Understand how to define the scope of an application and determine the algorithms necessary, and why it’s important
• Learn how to use industry-standard interfaces such as RS-232, RS-485, and GPIB
• Create low-level extension modules in C to interface Python with a variety of hardware and test instruments
• Explore the console, curses, TkInter, and wxPython for graphical and text-based user interfaces
• Use open source software tools and libraries to reduce costs and avoid implementing functionality from scratch

Book Description

Python Algorithms explains the Python approach to algorithm analysis and design. Written by Magnus Lie Hetland, author of Beginning Python, this book is sharply focused on classical algorithms, but it also gives a solid understanding of fundamental algorithmic problem-solving techniques.

• The book deals with some of the most important and challenging areas of programming and computer science, but in a highly pedagogic and readable manner.
• The book covers both algorithmic theory and programming practice, demonstrating how theory is reflected in real Python programs.
• Well-known algorithms and data structures that are built into the Python language are explained, and the user is shown how to implement and evaluate others himself.

What you’ll learn

• Transform new problems to well-known algorithmic problems with efficient solutions, or show that the problems belong to classes of problems thought not to be efficiently solvable.
• Analyze algorithms and Python programs both using mathematical tools and basic experiments and benchmarks. Download Now »

Complete, Hands-On Guide to Building Advanced Distributed Applications with Ruby

Distributed programming techniques make applications easier to scale, develop, and deploy—especially in emerging cloud computing environments. Now, one of the Ruby community’s leading experts has written the first definitive guide to distributed programming with Ruby.

Mark Bates begins with a simple distributed application, and then walks through an increasingly complex series of examples, demonstrating solutions to the most common distributed programming problems.

Bates presents the industry’s most useful coverage of Ruby’s standard distributed programming libraries, DRb and Rinda. Next, he introduces powerful third-party tools, frameworks, and libraries designed to simplify Ruby distributed programming, including his own Distribunaut.

If you’re an experienced Ruby programmer or architect, this hands-on tutorial and practical reference will help you meet any distributed programming challenge, no matter how complex.

Book Description

Python is a dynamic programming language, which is completely enterprise ready, owing largely to the variety of support modules that are available to extend its capabilities. In order to build productive and feature-rich Python applications, we need to use MySQL for Python, a module that provides database support to our applications. Although you might be familiar with accessing data in MySQL, here you will learn how to access data through MySQL for Python efficiently and effectively.

This book demonstrates how to boost the productivity of your Python applications by integrating them with the MySQL database server, the world’s most powerful open source database. It will teach you to access the data on your MySQL database server easily with Python’s library for MySQL using a practical, hands-on approach. Leaving theory to the classroom, this book uses real-world code to solve real-world problems with real-world solutions.

The book starts by exploring the various means of installing MySQL for Python on different platforms and how to use simple database querying techniques to improve your programs. It then takes you through data insertion, data retrieval, and error-handling techniques to create robust programs. The book also covers automation of both database and user creation, and administration of access controls. As the book progresses, you will learn to use many more advanced features of Python for MySQL that facilitate effective administration of your database through Python. Every chapter is illustrated with a project that you can deploy in your own situation. Download Now »

Book Description

Beginning Rails 3 is the practical starting point for anyone wanting to learn how to build dynamic web applications using the latest release of the Rails framework for Ruby. You’ll learn how all of the components of Rails fit together and how you can leverage them to create sophisticated web applications with less code and more joy.

This book is particularly well suited to those with little or no experience with web application development, or who have some experience but are new to Rails. Beginning Rails 3 assumes basic familiarity with web terms and technologies, but doesn’t require you to be an expert. Rather than delving into the arcane details of Rails, the focus is on the aspects of the framework that will become your pick, shovel, and axe. Part history lesson, part introduction to object-oriented programming, and part dissertation on open source software, this title doesn’t just explain how to do something in Rails, it explains why.

• Learn to create Rails web applications from scratch
• Includes a gentle introduction to the Ruby programming language
• Completely updated to include the new features of Rails 3
