PostgreSQL streaming replication for Ansible Tower

Posted on May 31, 2017

Ansible Tower 3.1 has recently been released, and it does implement real HA. In fact, up to version 3.0, Ansible Tower multi-node installation, only allowed a single machine to be primary and the switch was not possible in an automated fashion, so if the primary Ansible Tower would have collapsed, an operator should have promoted one of the secondary Ansible Tower to be primary to be able to carry on the work.

Posted on December 22, 2015

Innotop is a tool that allows you to control the status of a MySQL/MariaDB database. It is widely used since it shows the data with an interface very similar to the top one.

To solve this, I found a patch online and, after some testing, I’ve added it to the Fedora package.

The material is divided in three sections: Keynotes (14 videos), Tutorials (64 videos) and Sessions (81 videos). The Keynotes are really short video (7~15 minutes each) that tend to be some sort of advertise of the companies that are sponsors (I guess) of the event.
