I send a lot of mail in my apps. I wanted a way to keep track of what emails are sent. I also wanted a way to manage my mailers from ActiveRecord so I didn’t have to push every time I made a change (a feature inspired by my hosting days, where I used WHMCS).
This does all that by hooking into ActionMailer and doing some cool things. I’m really proud of it, though it’s not that popular.
Mattermost is a great open-source chat platform, very similar to Slack. They have an API, but no official Ruby client, so I made a Ruby client.
When I don’t deploy to Heroku, I deploy to a node running Ubuntu. This is a collection of recipes and controls for the amazing Mina — which is like Capistrano, but better.
I use ActiveAdmin for all my projects because I don’t want to have to write CRUD/filters/sortable tables for every resource I have. This gem adds a dropdown menu to each resource that contains links to every associated resource, for quick filtering and lookup.
