Beginning R, 2nd Edition
Beginning R, 2nd Edition is a hands-on book showing how to use the R language, write and save R scripts, read in data files, and write custom statistical functions as well as use built in functions. This book shows the use of R in specific cases such as one-way ANOVA analysis, linear and logistic regression, data visualization, parallel processing, bootstrapping, and more. It takes a hands-on, example-based approach incorporating best practices with clear explanations of the statistics being done. It has been completely re-written since the first edition to make use of the latest packages and features in R version 3. R is a powerful open-source language and programming environment for statistics and has become the de facto standard for doing, teaching, and learning computational statistics. R is both an object-oriented language and a functional language that is easy to learn, easy to use, and completely free. A large community of dedicated R users and programmers provides an excelle ...

Hack and HHVM
A couple of years ago, Facebook switched its production servers from a PHP-to-C++ compiler to their own HipHop Virtual Machine (HHVM) and then launched a new version of PHP to run on HHVM called Hack. This comprehensive guide—written by a member of the core HHVM and Hack teams at Facebook—shows you how to get up and running with both HHVM and Hack. What makes them useful? The HHVM engine is faster and more performant than the Zend engine, which can save Facebook and other large-scale sites millions of dollars in servers and maintenance. And while the Hack language looks and acts like PHP, it also contains new features such as static typing, generics, native collections, which PHP developers have long needed. Pick up this book and explore two important programming innovations that help Facebook run a tighter ship. ...

Clojure Web Development Essentials
Functional programming enables developers to create and deploy applications quickly and easily. Using the Clojure programming language and the Leiningen build tool, this book teaches you how to leverage various Clojure libraries into the building blocks of a web-based application. We'll start by generating a new, fully runnable, baseline web application using the Leiningen Luminus template. From there we'll examine the different pieces that compose our application, and learn the basics of the underlying Ring framework. Subsequent chapters will focus on each technology and leverage those technologies to build additional functionality into our application. You'll learn how to validate user submitted data, authentication, account creation, how to interact with a database, and more. Finally, we'll create an environment configuration and deploy our app. By the end of this book you'll have created a full fledged application from start to finish, and you'll have the requisite skills to ...
