问题 I have an fs filestream being used to serve file downloads which are dynamically created. I get this stream and pipe it to my response object after setting appropriate headers. I also set a couple stream events so that if there's an error or the stream ends, it removes the generated files from the file system. I'm running into an issue where, on occasion, when the download isn't correctly initialized or finished there may be some hanging files left on the file system. I believe this is

问题 scrollTop doesn't work every other click (every second click). I use will_paginate at the bottom of the page. When I click on a link, the page is refreshed and the display position is at the bottom of the page. Then I click on a link to another page, the page is refreshed and the display position is at the top of the page as I expect.

问题 I am currently looking to use RequireJS to ensure modularity in the front end side of my project written in Coffeescript.
