Rails: Have different session secrets for all environments
The Rails secret_token must be unique for each application and any instance of it. If not, someone could exploit this by creating a user with ID = 1 (e.g. on staging), sign in and then use that cookie to authenticate on another site (e.g. on production, where the user with ID = 1 probably is the admin).
Here is a one-for-all solution that does not affect current production users, leaving the production token unchanged: prefix the existing secret_token with #{Rails.env unless Rails.env.production?}.
Note: There may be tokens in ...
Make your Rails console (and irb) output better readable
Pour color on your Rails console with awesome_print. Turn confusing long strings into formatted output. Have objects and classes laid out clearly whenever you need it.

Automatically validating dependency licenses with License Finder
"Open-source software (OSS) is great. Anyone can use virtually any open-source code in their projects."
Well, it depends. Licenses can make things difficult, especially when you are developing closed-source software. Since some OSS licenses even require the employing application to be open-sourced as well (looking at you, GPL), you cannot use such software in a closed-source project.
To be sure on this, we have developed a project-level integration of Pivotal's excellent [license_finder](https:/...
