Erlang is a development platform, proven in large systems for more than two decades, that offers highly-efficient concurrency, scalability, and fault-tolerance. Elixir is a modern programming language that takes advantage of the Erlang Virtual Machine without the complex syntax and conventions of the Erlang language. The Elixir language offers Ruby-like elegance along with the power to develop bulletproof scalable, fault tolerant, distributed server systems that can handle massive numbers of simultaneous clients and run with almost no downtime. Elixir in Action teaches you to apply the new Elixir programming language to practical problems associated with scalability, concurrency, fault-tolerance, and high-availability. This book starts with a quick overview of the Elixir language, mapping familiar language concepts to the Elixir syntax. Then, you'll learn to think about problems from the Elixir mindset, which builds on the model of functional-style programming. With a solid foundation, you'll confidently explore Elixir's seamless integration with the Erlang Virtual Machine and supporting OTP library that offers battle-tested, industry proven abstractions you can use immediately in your applications. Finally, the book provides guidance on how to create deployable releases, distribute the system over multiple machines, and control the running system in production.

Don't accept the compromise between fast and beautiful: you can have it all. Phoenix creator Chris McCord, Elixir creator Jose Valim, and award-winning author Bruce Tate walk you through building an application that's fast and reliable. At every step, you'll learn from the Phoenix creators not just what to do, but why. Packed with insider insights and completely updated for Phoenix 1.3, this definitive guide will be your constant companion in your journey from Phoenix novice to expert, as you build the next generation of web applications. Phoenix is the long-awaited web framework based on Elixir, the highly concurrent language that combines a beautiful syntax with rich metaprogramming. The best way to learn Phoenix is to code, and you'll get to attack some interesting problems. Start working with controllers, views, and templates within the first few pages. Build an in-memory context, and then back it with an Ecto database layer, complete with changesets and constraints that keep readers informed and your database integrity intact. Craft your own interactive application based on the channels API for the real-time applications that this ecosystem made famous. Write your own authentication plugs, and use the OTP layer for supervised services. Organize code with modular umbrella projects. This edition is fully updated for Phoenix 1.3, Elixir 1.3, and Ecto 2.1, with a new chapter on using Channel Presence to find out who's connected, even on a distributed application. Use the new generators and the new ExUnit features to organize tests and make Ecto tests concurrent. This is a book by developers and for developers, and we know how to help you ramp up quickly. Any book can tell you what to do. When you've finished this one, you'll also know why to do it.

《The Little Schemer：递归与函数式的奥妙》是一本久负盛名的经典之作，两位作者Daniel P. Friedman、Matthias Felleisen在程序语言界名声显赫。《The Little Schemer：递归与函数式的奥妙》介绍了Scheme的基本结构及其应用、Scheme的五法十诫、Continuation-Passing-Style、Partial Function、Y-Combinator、Interpreter等内容，并通过这些内容阐述了计算的一般本质。《The Little Schemer：递归与函数式的奥妙》没有什么理论性描述，所有概念都蕴含在独特的引导式一问一答过程中，这种方式让读者对程序大师运用熟稔的程序方法来驾驭概念的能力叹为观止。 通过阅读《The Little Schemer：递归与函数式的奥妙》，可以让读者领略递归的奥妙、函数式编程风格的魅力。阅读完毕会有一种意犹未尽的感觉。 《The Little Schemer：递归与函数式的奥妙》适合所有程序员阅读，特别是函数式编程爱好者。好好享用！

《计算机底层的秘密》以图解的方式通俗易懂地讲解计算机系统中各项技术的本质，包括编程语言的本质是什么、操作系统、进程线程协程等的本质是什么、到底什么是内存、什么是堆区栈区、内存分配等是怎么一回事、怎样从晶体管构建出CPU、I/O是如何实现的等等，从根源出发，一步步讲解一项技术到底是怎么来的，同时内容可视化——辅助大量精心设计的插图，几乎做到了平均一页有一图，把对技术的理解门槛尽量降低。
