Finally, Simple Form support Boostrap 3. 👏

But I found it still dosen't support some components in Bootstrap 3. Or may be in the future. But I can't wait, so I find a solution to support them. It was inspired by heartcombo/simple_form#531 (comment) .

This is a final solution and I used in my project.

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

最近在看Sinatra 1.3.5的源码。在Sinatra::Helpers模块中看到一个名为uri的方法，用来将一个相对路径转换为绝对路径。在该函数的代码中看到分别针对request.script_name和request.path_info进行了处理。但是并不清楚这两个参数的区别，于是做了一些reseach。

二者在RFC3875中有如下定义：

4.1.13. SCRIPT_NAME

The SCRIPT_NAME variable MUST be set to a URI path (not URL-encoded) which could identify the CGI script (rather than the script's output). The syntax is the same as for PATH_INFO (section 4.1.5) >

	2) update brunch-config.js
	3) remove Bootstrap from web/static/css/app.css
	4) rename web/static/css/app.css to web/static/css/app.scss
	5) update web/static/css/app.scss

	// These two need to be declared outside the try/catch
	// so that they can be closed in the finally block.
