Notes is simple, single user, notes taking app written in Rails 4.
I use it for taking technical notes (snippets of code, unix commands for specific tasks, simple how tos...). It has awesome and super fast instant search so I can find any note in just a second. I use it on daily basis in my work.
You can simply create your own copy on heroku with following steps:
Clone repository:
$ git clone git@github.com:mrhead/notes.git
Create heroku app:
$ cd notes
$ heroku create [your_app_name]
$ git push heroku master
$ heroku run rake db:migrate # in case of connection issues run: heroku run:detached rake db:migrate
Set your login and password:
$ heroku config:set login=your_login
$ heroku config:set password=your_password
And open it in the browser:
$ heroku open
Enjoy it!
