• Enforce "spaces" or "tabs" only in python files ?

I keep getting files with mixed indentation and this is annoying... (to say the least) Python itself can tell when there is a problem, but I am searching something to do that at the editor level, like it exists for the charset.

  I have been searching the web for recent benchmarks measuring Grails overall performance compared to its competitors (Rails, Django, ASP.NET MVC...), but I didn't find anything more recent than a 3 years-old article with obsolete grails version (0.5). See here and here. So, starting from grails 1.2, are there any more recent grails benchmarks you are aware of ?
