Speed up Mongrel / RubyOnRails development

Paul Asmuth — Mon, 01 Feb 2010 12:08:05 +0000

This is great! With the Talentsuche.de RubyOnRails app growing the mongrel development server was getting slow and slower. Lately a request took up to 3000ms - that's unusable for front end development.

But there is quick way to speed this up. Mongrels default behaviour is to listen on all interfaces/addresses (0.0.0.0). By setting a single ip you can make it a lot faster.

 ./script/server -b 10.23.23.23 -p 3000

Facebook: See friends of hidden profiles

Apparently facebook's autocomplete-script for the friends search returns data it's not supposed to.

Even hidden profiles's friends are revealed. All you need is the profiles uid, which is public.

The url of the php script is:

Custom mime types in Rails

Paul Asmuth — Sat, 05 Sep 2009 14:50:01 +0000

To register a custom mime type in Rails, call the register method from your controller:

Mime::Type.register "image/jpeg", :jpg

Your mime type can be used in the respond_to block now:

format.jpg do 
  #do something
end
