Getting started with Puppet - Part 1 - Sandbox setup

What is Puppet?

Puppet is a great product that enables IT infrastructure automation at scale. Produced by Puppet Labs, it is an open source product that also has a paid Enterprise version with additional features. It runs on Unix based operating systems and Windows. It has its own declarative language to allow programmers to script for automating infrastructure provisioning and configuration.

To get started with learning Puppet, I recommend using the Puppet learning Virtual Machine. Alternatively, any default Vagrant box has a Puppet client pre-installed. For the purpose of this tutorial, I will be using, which I covered in a prior post titled 'Create a on'. From that post, follow the basic instructions for creating a free account in and continue below after getting to the console.

Installing Puppet client on

In the console, execute the following commands.

sudo apt-get update
sudo apt-get install puppet
puppet --version

I showed him how to create cards, add labels to them and move them from To Do, to Doing to Done. I had him create some cards and label them. He could not stop creating cards. I could not convince him to go to bed after that. He created cards for everything he wants to do in the summer and he is not done with creating cards. He even created a card to email a screenshot of his Trello board to his teacher.

Later last night, he was still awake in bed when I checked on him. He told me that he wanted to add three more labels - Math, Science and One-on-One. He wanted a label titled 'One-on-one' for tasks that he wants to do with me and he wants one-on-one att…

A @trello board to get kids excited - continued

This is a continuation of the previous post titled - A trello board to get kids excited. At the time of writing this post, the previous post had 198 page views. I wish people commented. I did get some positive feedback on Twitter. The Trello twitter account re-tweeted my tweet and also sent out a second tweet advertising the page. Thank you very much. I hope a lot of parents and kids benefited and had fun as a result.

Trello people: Idea - How about a 'Trello Kiddo'? Perhaps you could offer that to schools that give iPads for each kid to take home with them. Get them when they are young.

When a kid does something religiously, regularly and feels great about it and can't wait to tell everyone about it, you know you've done well as a parent. We realized that we needed a separate column to keep track of 'Special accomplishments'. Positive reinforcement that you can see with your eyes!

Some parents feel like they haven't done enough for their kids, particularly…
