Forwarding ports from a docker container with Vagrant 1.6

Vagrant 1.6 has a really nice feature which allows you to run a docker environment from any machine that can run Vagrant (even a Mac)

Behind the scenes, Vagrant creates a host VM which runs the docker containers.

The "gotcha" is: Vagrant won't automatically forward ports all the way back from the container->vagrant host VM->your mac. You have to do that step manually, by configuring your own host VM for Vagrant to use for hosting docker containers with. That host VM is told what ports to open.

Here's how I set up a local Wordpress development testing container.

Auto-starting VirtualBox VMs on OS X

After finding a lot of other posts on the topic that didn't work out for me this one did the trick so I'm reposting for my own sense of self preservation.

Link to original article.

Copy the Virtualbox autostart plist template file to your system's LaunchDaemons folder.

sudo cp \

/Applications/VirtualBox.app/Contents/MacOS/org.virtualbox.vboxautostart.plist \

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.
