The Time.iso8601 method is a restricted subset of ISO-8601. Does anyone know what the limitations are? Does anyone know of a full implementation for Ruby? I'm using MRI 1.8.7 Thanks Update It looks like there isn't a single class that handles all of the various 8601 date and date/time combinations. However I have managed to wo...

Am I correct that if someone wrote a Ruby plugin for a web browser and a user installed that plugin then it would be possible to replace javascript with ruby on the frontend? Aren't there any plugins for this? Or even for using other languages than javascript on the browser side? ...

Imagine a web application that allows a logged in user to run a shell command on the web server at the press of a button. This is relatively simple in most languages via some standard library os tools. But if that command is long running you don't want your UI to hang.
