原文：Summary: How I Learned to Program using Ruby

• I spent some time learning what “programming” and “web applications” are in general, then deconstructed these skills into smaller sub-skills that are easier to understand and practice.

• I set my target performance level by choosing two specific projects I wanted to create, then defined what those projects would look like when finished.

• I deconstructed those projects into smaller sub-steps then identified which sub-steps seemed most important.

• I made sure I had the tools I needed to work (like the latest version of Ruby), and that I was able to find and use any additional tools I needed.

• I found a few reliable sources of programming information, but I skipped canned tutorials in favor of jumping in and writing the actual programs.

• I worked on the most important sub-steps first, like figuring out how to test programs on my computer, push the finished application to production, etc.

• I used reference examples to get started and build confidence, then tested various approaches to figure out how to program the features I wanted.

• When I made an error, the program crashed and gave me an error message, creating a fast feedback loop.

• After getting an error, I experimented with several ways to fix it. If I couldn’t fix the problem myself, I searched for help.

• I kept using the build / test / fix approach until my programs were complete.

   

  概要：学习ruby编程的方法

• 首先花了一些时间了解普通编程和web应用编程之间的共性，然后，把他们分解成简单易懂并且易于练习的小技巧。

• 通过选择两个特殊的项目来设定目标项目的难易程度。然后定义这两个项目做完之后所具有的功能。

• 把项目分解成更小的模块，找出最重要的模块。

• 确保已经有了所需要的开发工具（比如最新版的ruby）。

• 待补充

• 首先完成最重要的子任务，比如如何自己测试这个项目，如果把最终版本做成产品等

• 开始会参考一些例子来增加自信，然后尝试各种方法实现我想要的程序

• 当我犯了错，程序崩溃并且给我返回一个错误提示信息，这时候要创建一个快速反馈机制

• 出错后，尝试各种方法来解决这个问题，如果自己无法解决，我会寻求别人的帮助

• 我会一直使用构建/测试/修复知道我的项目成功完成。
