JavaScript Regular Expressions
Regular expressions are patterns or templates that allow you to define a set of rules in a natural yet vague way, giving you the ability to match and validate text. Therefore, they have been implemented in nearly every modern programming language. JavaScript's implementation allows us to perform complex tasks with a few lines of code using regular expressions to match and extract data out of text. This book starts by exploring what a pattern actually is and how regular expressions express these patterns to match and manipulate user data. You then move on to learning about the use of character classes to define a wild character match, a digit match, and an alphanumeric match. You will then learn to manipulate text and shorten data in URLs, paths, markup, and data exchange, as well as other advanced Regex features. Finally, you will work through real-world examples, both in the browser and on the server side using Node.js. ...

The book begins by teaching you how to capture audio and video streams from the browser using the Media Capture and Streams API. You will then create your first WebRTC application capable of audio and video calling. The book will also give you in-depth knowledge about signaling and building a signaling server in Node.js. While being introduced to the RTCDataChannel object, you will learn how it relates to WebRTC and how to add text-based chat to your application. You will also learn to take your application further by supporting multiple users through different technologies and scale its performance and security. This book will also cover several theories using full mesh networks, partial mesh networks, and multipoint control units. By the end of this book, you will have an extensive understanding of real-time communication and the WebRTC protocol and APIs. ...

AWS System Administration
After getting over the excitement of the scaling and cost-saving possibilities offered by Amazon Web Services, system administrators quickly come up against complexities and gotchas in the management of systems. How can they make sure auto-scaling kicks in when it is suppose to? How do they make sure DNS sends traffic to the right systems? How do they integrate automated management tools such as Chef and Puppet? This book is a comprehensive guide to the administrative features of AWS and how to make the most of them to minimize your administrative work. You'll learn how to configure and manage powerful AWS tools, such as CloudFormation, OpsWorks, Elastic Load Balancing, and Route 53. AWS administration is no easier than stand-alone server administration - it's just different, and very rewarding once you set up your automation right. This book shows you how. ...

Mastering pandas for Finance
This book will teach you to use Python and the Python Data Analysis Library (pandas) to solve real-world financial problems. Starting with a focus on pandas data structures, you will learn to load and manipulate time-series financial data and then calculate common financial measures, leading into more advanced derivations using fixed- and moving-windows. This leads into correlating time-series data to both index and social data to build simple trading algorithms. From there, you will learn about more complex trading algorithms and implement them using open source back-testing tools. Then, you will examine the calculation of the value of options and Value at Risk. This then leads into the modeling of portfolios and calculation of optimal portfolios based upon risk. All concepts will be demonstrated continuously through progressive examples using interactive Python and IPython Notebook. By the end of the book, you will be familiar with applying pandas to many financial problems, gi ...
