Python for Data Analysis is concerned with the nuts and bolts of manipulating, processing, cleaning, and crunching data in Python. It is also a practical, modern introduction to scientific computing in Python, tailored for data-intensive applications. This is a book about the parts of the Python language and libraries you’ll need to effectively solve a broad set of data analysis problems. This book is not an exposition on analytical methods using Python as the implementation language.

Written by Wes McKinney, the main author of the pandas library, this hands-on book is packed with practical cases studies. It’s ideal for analysts new to Python and for Python programmers new to scientific computing.

  • Use the IPython interactive shell as your primary development environment
  • Learn basic and advanced NumPy (Numerical Python) features
  • Get started with data analysis tools in the pandas library
  • Use high-performance tools to load, clean, transform, merge, and reshape data
  • Create scatter plots and static or interactive visualizations with matplotlib
  • Apply the pandas groupby facility to slice, dice, and summarize datasets
  • Measure data by points in time, whether it’s specific instances, fixed periods, or intervals
  • Learn how to solve problems in web analytics, social sciences, finance, and economics, through detailed examples

A practical introduction to Node, the exciting new server-side JavaScript web development stack

  • Go from nothing to a database-backed web application in no time at all
  • Get started quickly with Node and discover that JavaScript is not just for browsers anymore
  • An introduction to server-side JavaScript with Node, the Connect and Express frameworks, and using SQL or MongoDB database back-end

In Detail

Node is an exciting new technology stack that brings JavaScript to the server-side of web applications for the first time. Node means that JavaScript is no longer just for browsers. It’s for web application development, it’s for developing any internet protocol, it’s for the real-time web, it’s for command line scripts, and much more.

Node Web Development gives you an excellent starting point straight into the heart of developing server side web applications with node. You will learn, through practical examples, how to use the HTTP Server and Client objects, the Connect and Express application frameworks, the algorithms for asynchronous execution, and use both SQL and MongoDB databases.

This book is the ideal companion for getting started with Node. Starting with practical advice on installing Node for both development and application deployment, you will learn how to develop both HTTP Server and Client applications. Many different ways of working with Node are shown, including using database storage engines in applications and developing websites both with and without the Connect/Express web application framework. You will also get an introduction to Node’s CommonJS module system allowing you to implement an important subset of object-oriented design.

What you will learn from this book

  • Discover the role of server-side JavaScript in web application development
  • Make informed architecture choices in Node for performance and throughput
  • Install and use Node for both the development and deployment of server-side web applications
  • Use the Connect and Express application frameworks
  • Set up either SQL or MongoDB database systems in your application
  • Learn the difference between synchronous and asynchronous algorithms and why they are important

Approach

This book is a practical introduction to learning about Node. Each chapter introduces you to a different area of Node, using screenshots and examples to get you up and running as quickly as possible.

Who this book is written for

If you are a developer who wants to use JavaScript on the server side in order to build quicker, higher performing web applications, then this book is for you. It is recommended that you should have at least a rudimentary understanding of JavaScript and web application development.

Ajax is no longer an experimental approach to website development, but the key to building browser-based applications that form the cornerstone of Web 2.0. Head First Ajax gives you an up-to-date perspective that lets you see exactly what you can do — and has been done — with Ajax. With it, you get a highly practical, in-depth, and mature view of what is now a mature development approach.

Using the unique and highly effective visual format that has turned Head First titles into runaway bestsellers, this book offers a big picture overview to introduce Ajax, and then explores the use of individual Ajax components — including the JavaScript event model, DOM, XML, JSON, and more — as it progresses. You’ll find plenty of sample applications that illustrate the concepts, along with exercises, quizzes, and other interactive features to help you retain what you’ve learned.

Head First Ajax covers:

  • The JavaScript event model
  • Making Ajax requests with XMLHTTPREQUEST objects
  • The asynchronous application model
  • The Document Object Model (DOM)
  • Manipulating the DOM in JavaScript
  • Controlling the browser with the Browser Object Model
  • XHTML Forms
  • POST Requests
  • XML Syntax and the XML DOM tree
  • XML Requests & Responses
  • JSON — an alternative to XML
  • Ajax architecture & patterns
  • The Prototype Library

The book also discusses the server-side implications of building Ajax applications, and uses a “black box” approach to server-side components.

Head First Ajax is the ideal guide for experienced web developers comfortable with scripting — particularly those who have completed the exercises in Head First JavaScript — and for experienced programmers in Java, PHP, and C# who want to learn client-side programming.
