Easy way to copy one git branch to another local branch

At my work we use a couple of branches for deployment with CodeShip. When we push one of our ‘build’ branches, Codeship automatically starts a new build on it, and deploys if all tests pass. One of these is our QA branch. For this reason it is beneficial for us to have a quick workflow to make one of these branches behave like a dev branch we want to test-deploy.

Step two

Find your Google Plus profile URL. You will find it by going to http://plus.google.com, signing in, and then clicking the little arrow next to your picture. Out will pop a small menu where you can click “Show profile”. Clicking this will take you to your profile, and you can get your profile URL from the address bar. Mine is https://plus.google.com/115125376004755233882

Step three

Go to your profile page (Users -> Your profile). There are two places to enter Google plus profile URL here. One under “Contact Info”, the other under “Google Plus profile information”. Add your profile URL to both.

On the “About” page, find the “Links” section, and click to edit it.

All done

Presto! You have now successfully linked your WordPress and Google Plus, giving your blog that extra personal feel. If you would like to test it out, go to http://www.google.com/webmasters/tools/richsnippets, and enter the URL of any one of your blog posts. You should see your pretty face next to it. Enjoy!
