install ruby when you don't do much ruby but want to download a gem

when gem install trello_cli yields permission errors:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

you should download another ruby and use that as the default.

nginx on OSX

I was trying to open some index.html file that attempts to load in a json file and got the following error:

Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

Turns out this error gets thrown in chrome if your web page isn't being served up via a proper webserver credits here
