# 致中國讀者 Ruby 是一門優美的計算機語言，其設計原則是“讓編程人員快樂”。David Heinemeier Hansson 就是看重了這一點，才在開發 Rails 框架時選擇了 Ruby。Rails 常被稱作 Ruby on Rails，它讓 Web 開發變得從未這么快速，也從未這么簡單。在過去的幾年中，《Ruby on Rails Tutorial》這本書被視為介紹使用 Rails 進行 Web 開發的先驅者。 在這個全球互聯的世界中，計算機編程和 Web 應用開發都在迅猛發展，我很期待能為中國的開發者提供 Ruby on Rails 培訓。學習英語這門世界語言是很重要的，但先通過母語學習往往會更有效果。正因為這樣，當看到安道把《Ruby on Rails Tutorial》翻譯成中文時，我很高興。 我從未到過中國，但一定會在未來的某一天到訪。希望我到中國時能見到本書的一些讀者！ 衷心的祝福你們， Michael Hartl 《Ruby on Rails Tutorial》的作者 附原文： Ruby is a delightful computer language explicitly designed to make programmers happy. This philosophy influenced David Heinemeier Hansson to pick Ruby when implementing the Rails web framework. Ruby on Rails, as it’s often called, makes building custom web applications faster and easier than ever before. In the past few years, the Ruby on Rails Tutorial has become the leading introduction to web development with Rails. In our interconnected world, computer programming and web application development are rapidly rising in importance, and I am excited to support Ruby on Rails in China. Although it is important to learn English, which is the international language of programming, it’s often helpful at first to learn in your native language. It is for this reason that I am grateful to Andor Chen for producing the Chinese-language edition of the Ruby on Rails Tutorial book. I’ve never been to China, but I definitely plan to visit some day. I hope I’ll have the chance to meet some of you when I do! Best wishes and good luck, Michael Hartl Author The Ruby on Rails Tutorial
