Run a remote ruby script locally.

If you ever want to try a ruby script without downloading it you can do it like this:

ruby -e "$(curl -fsSL"

I know this is not rocket science but i want to have this line handy.


rake routes filtered by controller

rake routes CONTROLLER=controller_name


Paperclip content type validation always fails on Internet Explorer

I just ran into a strange problem. It turns out that when you try to upload a file using paperclip on IE, the content-type is different from other browsers and you have to take of them if you want to use paperclip’s validates_attachment_content_type method.

I needed to add to my model validation the following content-types: “image/pjpeg” and “image/x-png”. I did not have a problem with gifs.

validates_attachment_content_type :logo, :content_type => ['image/jpeg', 'image/jpg', 'image/gif', 'image/png', 'image/pjpeg', 'image/x-png']



Never fade away

Not what you wanted

They kind of remind me of “The Killers”


Don’t listen to people, listen to yourself. That’s all I have to say at the end of the day. You’re the most important person to you. If you are doubting yourself, you are doubting any sort of success that you have set for yourself. Make your decisions and run with it. You can always fix something if it’s broken…but…you can’t do anything if you don’t even start.

Don’t play by the rules
