email for Rails Girls organisers to forward to their networks

Hi there,

If you're interested in taking your web journey to the next level and would love to contribute to the open source community, consider applying for a paid scholarship for this year's Rails Girls Summer of Code.

It will run from July to September 2014, and will see you contribute to an open source project of your choice. You'll be increasing your coding skills, with help from a coach or two, and will be making a significant contribution to the community.

Applications close May 2nd, but there's a fair bit to do before then, so don't delay. :) Read more on what's required in the application guide.

If you're curious and want to know more first, you can check out the FAQ.

Want to delete a lot of old hosted zones on Route53? This should take the pain away.

AWS Route53 Hosted Zone Cleaner

Why?

My org buys lots of domains and configure lots of records on AWS. Removing them is a pain though; you have to remove each record set before you can remove the hosted zone. This makes it much more straightforward.

Feel free to use this; but you're on your own. I am not responsible if you break something.

Setup

You'll need ruby/ruby-gems and your AWS API credentials.
