Custom Web Fonts and the Rails Asset Pipeline
View web-fonts-asset-pipeline.md

Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

mac 删除svn文件
View svn
有时复制一个已经存放在svn的项目时,会把里面的svn文件也复制了过去。所以再次提交到svn时会出现 under version control.
所以用以下命令清除项目下的svn文件。
sudo find /Applications/MAMP/htdocs/jumpqsina/ -name ".svn" -exec rm -r {} \;

contentInset contentSize和contentOffset区别
View gist:2593453
http://developer.apple.com/library/ios/#documentation/WindowsViews/Conceptual/UIScrollView_pg/CreatingBasicScrollViews/CreatingBasicScrollViews.html
contentSize是scrollview可以滚动的区域,比如frame = (0 ,0 ,320 ,480) contentSize = (320 ,960),
代表你的scrollview可以上下滚动,滚动区域为frame大小的两倍。
contentOffset是scrollview当前显示区域顶点相对于frame顶点的偏移量,比如上个例子你拉到最下面,
contentoffset就是(0 ,480),也就是y偏移了480
//与margin类似
contentInset是scrollview的contentview的顶点相对于scrollview的位置,例如你的contentInset = (0 ,100),那么你的contentview就是从scrollview的(0 ,100)开始显示
