Book Description
The Basal ganglia, to adopt a phrase of Churchill's, are "a riddle wrapped in a mystery, inside an enigma." And although there is a wealth of information available on them, this research field remains controversial due in part to the diverse number of disciplines involved. A Theory of the Basal Ganglia and Their Disorders provides a clear, coherent

Book Description
This book is the "Hello, World" tutorial for building products, technologies, and teams in a startup environment. It's based on the experiences of the author, Yevgeniy (Jim) Brikman, as well as interviews with programmers from some of the most successful startups of the last decade, including Google, Facebook, LinkedIn, Twitter, GitHub, Stripe, Instagram, AdMob, Pinterest, and many others. Hello, Startup is a practical, how-to guide that consists of three parts: Products, Technologies, and Teams. Although at its core, this is a book for programmers, by programmers, only Part II (Technologies) is significantly technical, while the rest should be accessible to technical and non-technical audiences alike. If you’re at all interested in startups—whether you’re a programmer at the beginning of your career, a seasoned developer bored with large company politics, or a manager looking to motivate your engineers—this book is for you.

Book Description
Today's modern Rails applications have lots of moving parts. Make sure your next production deployment goes smoothly with this hands-on book, which guides you through the entire production process. You'll set up scripts to install and configure all the software your servers need, including your application code. Once you're in production, you'll learn how to set up systems to monitor your application's health, gather metrics so you can stop problems before they start, and fix things when they go wrong.Deploying Rails takes you on a expertly guided tour of the current best practices in Rails deployment and management. You'll find in-depth explanations on effectively running a Rails app by leveraging popular open source tools such as Puppet, Capistrano, and Vagrant. Then you'll go beyond deployment and learn how to use Ganglia and Nagios to monitor your application's health and gather metrics so you can head off problems before they happen.You'll start out by building your own virtual environment by writing scripts to provision a production server with Vagrant and Puppet. Then you'll leverage the popular Rails deployment tool Capistrano to deploy an application into this infrastructure. Once the app is live, you'll monitor your application's health with Nagios, and configure Ganglia to collect system metrics. Finally, you'll see how to keep your data backed up, recover data when things go wrong, tame your log files, and use Puppet to automate everything along the way.Whether you're a Rails developer who wants a better understanding of the needs of a production Rails system, if you're a system administrator who wants to manage a Rails application, or if you're bridging the gap between development and operations, this book will be your roadmap to successful production deployment and maintenance, whether your application has ten users or ten million users.What You Need:The exercises and examples are most suited to a computer running some Unix variant, such as Mac OS X or Linux. But a Windows machine running Linux in a VirtualBox virtual machine is also sufficient. We'll show you how to set up a local virtual machine for your deployments; you won't need a dedicated server to hone your deployment skills. We expect you to have a basic familiarity with the Ruby programming language, the Ruby on Rails framework, and the Unix command line.
