If you’re using Ansible to provision/manage your infrastructure it only makes sense to utilize the same setup locally instead of having to go through all of the same configuration again. It eliminates a bunch of the “works on my machine” issues, it documents the entire process, makes it easier for new developers to get up to speed, etc.
When jumping back and forth between various Rails applications and projects it’s nice to have some tools to check on the state of the application.
I’ve been using Sunrise as my default calendar for a few months and I can’t imagine it any other way.
I share screenshots fairly often throughout the day when I'm working on projects. Most of my communication is via email and chat so sometimes it's easier to just share a screenshot instead of trying to explain what I'm seeing. OS X already makes it incredibly easy to take screenshots but navigating through finder when you want to upload the screenshot isn't as smooth but easily fixed with Stacks, a built in Dock feature.
Update: A much simpler way
For Little Feedback I wanted to have a blog to release new features on and post other updates to. It's a Rails application and I also wanted it to reside on the same top-level domain(www.littlefeedback.com/blog vs. blog.littlefeedback.com). There's a couple routes that come to mind for doing this.
