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.

Ninefold db updates

This is a quick way to Push or Pull your app database between your local machine and your Ninefold app server. "Pushing" is useful in the early stages of app development when you need to update seed data. "Pulling" is eternally useful for debugging.

  1. setup public key authentication (the SSH username is "user"). NB ensure you don't remove the existing SSH key - it's needed by the Ninefold Portal.

  2. obtain your database password from the "database" tab in the Ninefold portal.

  3. put the password where Postgres can find it (on the database server): echo "localhost:*:*:app:<PASSWORD>" > ~/.pgpass then chmod 0600 .pgpass more info on password files
