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.
Setting up an Octopress/Jekyll blog in your Rails application
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.
Testing your Ansible playbook with Semaphore
I was getting pretty tired of constantly running vagrant provision
after making changes to a pretty large playbook that I've been working on. The playbook I was working on has roles for setting up a full stack which takes a bit of time and you want to know that you can provision a server from scratch whenever you need.
Automating your development environment with Ansible
Ansible is a systems automation tool, similar to Chef and Puppet but with a very different approach. Ansible doesn't by default use a client-server model or a push-pull management style, it doesn't leave any artifacts behind and doesn't need to install anything to run on the server.
Monitoring multiple delayed job workers with Bluepill
It's really simple to have multiple workers going through your Delayed::Job queue and it's just as easy to start monitoring them properly with Bluepill.
