Sorry for somewhat wasting your time... ** I have a form that might or might not already contain data in its f...

What's the preferred way to handle rich text user input in rails? Markdown looks useful, but I haven't found an editor that looks simple to setup for it, nor am I sure how to handle sanitizing the html. (the sanitize helper still seems to allow stuff like </div>, which breaks my layout) I'd like to guarantee that the cleaned up code is v...

When in tinymce I press anything that is supposed to open a new window, such as color picker or a link dialog, FireFox/Chrome seems to start opening the window and then all of the sudden it opens a standard file download dialog asking if I am sure I want to download the requested html file. Sa...
Let's say I accidentally wrote this: do { } while (true); ...and then ran it. Apart from killing your browser, is there a way to stop javascript execution (the equivalent of Ctrl+Break in basic, or Ctrl+C)?
