Changing SmartGit Free Trial License to Non-Commercial

Some developers might overlook the license selection when using the SmartGit. Instead of choose non-commercial, they by default clicked Next on the “30 days Free Trial”. Worse thing is reinstall the SmartGit won’t get you to change the license.

To alter the license. First, go to

Windows: %APPDATA%\syntevo\SmartGit\<main-smartgit-version>
OS X: ~/Library/Preferences/SmartGit/<main-smartgit-version>
Unix/Linux: ~/.smartgit/<main-smartgit-version>

Put this in your `local-configure.yml` file, add as many users as you need:

    users:
      - name: fulvio
        sudoer: yes
        auth_key: ssh-rsa blahblahblahsomekey this is actually the public key in cleartext
      - name: plone_buildout
        group: plone_group
        sudoer: no
        auth_key: ssh-rsa blahblahblah ansible-generated on default

Updated Apr 5 2019:

because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

some other notes:

# Make sure your key is added to ssh-agent
ssh-add ~/.ssh/my_id_rsa

# ~/.ssh/config
Host my-remote-ansible-host
    ForwardAgent yes
# OR
# In your ansible.cfg file
[ssh_connection]
ssh_args = -o ForwardAgent=yes

Application specific host grouping in Riemann-dash

It is generally desirable to group all the hosts for a specific service into a single dashboard view. For example, all the web servers are in single view while all the database servers are in another view.

This is usually not an issue when you are sending custom metrics using Riemann client. However, there are cases where you are using something that you do not control how the metrics are being sent. i.e., Riemann-tools.

Since Riemann-tools scripts are application agnostic, in order for the dashboard view to group hosts, we must inject some application specific information into the tags field. Tags is a collection of arbitrary strings. In the case of Riemann-tools scripts you can pass in arbitrary strings on the command line.

riemann-health --host 127.0.0.1 --tag "prod" --tag "webserver"

Working with ansible-vault

---

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

I like Pages.app, but don't want to deal with constantly copying and pasting code around.

Here is how I do syntax highlighting in Pages.app by pressing a key command. It's based off of this post on stack exchange.

install pygments

sudo easy_install Pygments

install github syntax
