Provides a daily action plan filled with tips, tricks, and best practices to improve health for computer programmers, including how to mitigate back problems, carpal tunnel syndrome, and headaches.

Get Fit, Feel Better, and Keep Coding

The Healthy Programmer

You've heard about pair programming's benefits: fewer bugs, improved skills, and faster delivery. But what happens when you want to pair with someone in another city, country, or even hemisphere? With the right tools, you won't have to relocate to refactor. In this book, you'll learn techniques used by the most productive remote programmers in the industry to pair with anyone on the globe on any kind of project. You'll use collaborative editors, screen sharing, secure networking, and virtualization to create a remote pairing environment that feels as if your partner is sitting right next to you. Two heads are better than one, but only if they're working on the same problem. When pairing remotely, this requires a specialized environment that you'll learn how to create. We'll use the same open-source tools as the pros to improve collaboration and increase productivity. You'll learn techniques, patterns, and best practices you can apply to projects of all kinds. These tools are so effective that many co-located programmers use them despite sitting side-by-side--you don't have to work outside of an office for this book to improve your programming techniques. We'll start by creating a secure collaborative editing environment capable of handling the low-bandwidth networks at some coffee shops. Then we'll share your screen using free open source tools and protocols. We'll deploy all of this to a server in the cloud so you can access your development environment from anywhere. Then we'll use one of the most advanced integrated development environments to collaborate, sketch on a virtual whiteboard, and resolve conflicts. Finally, we'll talk with programmers at Pivotal Labs, Big Nerd Ranch, and other top-notch distributed development firms to learn how they handle the challenges of remote pairing on a daily basis. With their help and advice, you can be productive from any location on the planet. What You Need:Many of the examples in this book require an internet connection. You'll only need one computer for most of the exercises, and you can run them by yourself. But havinga second computer and even a second person may improve the experience.

Deploying with JRuby 9k

Deploy using the JVM's high performance while building your apps in the language you love. This book introduces you to three JRuby deployment strategies that give you the performance and scalability you need, while you use a language designed for rapid development. Explore common deployment scenarios, including consolidating an MRI-based Ruby deployment onto a single JVM process and porting a Rails application to JRuby, getting it into production, and keeping it running. This new edition has new chapters on Puma, performance tuning, and Java integration, and is updated to the latest versions of JRuby 9k, Rails 4, and JDK 8. JRuby is a fast, scalable, and powerful JVM language with all the benefits of a traditional Ruby environment. JRuby deployments have fewer moving parts and consume less memory than traditional Ruby. With this book, you can now use JRuby in the real world to build high-performance, scalable applications. Deploying your apps on the JVM requires some new approaches. Start by creating a JRuby microservice that takes advantage of the JVM's native concurrency. Then use Docker to build a virtual production environment that's a stable, reproducible place to explore JRuby deployment. Next, port an existing Rails application to JRuby, preparing the app to take advantage of the JVM platform--all while keeping everything that's friendly and familiar to Ruby developers. Deploy the Rails app to Docker with a multi-threaded Puma server to Heroku or your own private cloud. Take advantage of powerful Java libraries. See how JRuby fits into the enterprise by switching your app to use TorqueBox, an all-in-one JRuby environment that includes built-in support for messaging, scheduling, and daemons--perfect for handling the big jobs. Finally, take a deep dive into JVM performance tuning and set up a continuous deployment environment with Travis CI. What You Need: To run the examples in this book, you'll need a computer that can run the Java Virtual Machine and a connection to the Internet.
