RDS Production Termination Protection

Create a policy like this, substituting your AWS account number, then attach it to all groups and roles. It will prevent deletion of RDS instances containing the string "prod" in their name.

Note: This is intended to prevent accidental deletion, and is easily sidestepped.

boto3 quick hands-on

This documentation aims at being a quick-straight-to-the-point-hands-on AWS resources manipulation with [boto3][0].

First of all, you'll need to install [boto3][0]. Installing it along with [awscli][1] is probably a good idea as

• [awscli][1] is boto-based
• [awscli][1] usage is really close to boto's

Installing Ubuntu on a Mac

Desktop linux has been late to the show with high dpi support, but gnome seems to be leading the pack. I decided to try again. It's worked fairly well out of the box. Here are my steps if anyone wishes to repeat.

Booting into Ubuntu Live Image

• Download the iso from http://ubuntugnome.org/ubuntu-gnome-14-10-is-released/

• Insert usb stick, umount using diskutil and dd the image. (make sure to use the right devices when using dd, your setup may vary)
