A lot of times during my job I found myself with the need of Ansible Tower testing environments.
In the last few weeks I created a Vagrant script to actually automate it.
As this is a single host installation, which is usually more than enough for the majority of tests I do, the Vagrant file is very easy:
Vagrant.configure(2) do |config| # Set machine size config.vm.provider :libvirt do |domain| domain.memory = 2048 domain.

Lately I have been programming quite a bit and - for the first time - I have used Golang doing so. Go is a very nice language and really helped me with the development. One of the reasons why I have enjoyed this much Go is the standard library, which is amazing. I would like to share today the easiness of creating a basic Certificate Authority and signed certificates in Go.

After many years of using Hetzner as a server provider, and having rented from them multiple servers for many reasons, I decided to rent a server with 128Gb of RAM to do some tests with many (virtualized) machines on top of CentOS.
As it often happens, hosting providers put in place a lot of security measurements that sometimes make doing simple stuff more complex. The first approach I tried was using the (only) Ethernet interface as a bridged interface, but that did not brought me very far.

Sometimes I need to do some tests which are destructive and I need to perform them over and over until I figure out a process that reliably brings me to a desired state. I usually create some kind of easy to provision environments and work on it.
In the last few weeks I found myself working on an etcd cluster, so I created an environment with Vagrant, and since I had to write the majority of this by myself, since I have not found anything on Google that suited my needs, I’m going to share this with you.

FOSDEM is a must for all open source enthusiast in Europe and close by. I think that the reasons to go to FOSDEM are different from the reasons of many other conferences, but equally valid. The comparison with DevConf is obvious, due to the temporal closeness of the two events.
I think that DevConf is more about enterprise grade software (or close to be), while FOSDEM is more about experimentations and community.

I think this is a special moment of the year, where in less than two weeks is possible to meet a huge amount of Open Source contributors in person. Obviously you will need to take few flights, but it’s definitely worth.
DevConf this year was great. I’ve been able to assist to a huge amount of talks (more than 20) and the majority of which were very interesting.
As always in conferences, there are themes heavily discussed and other completely absent.

In Italy every year, during the last weekend of October, there is the Linux Day, an “open day” for the LUGs where they create events to publicize GNU/Linux and the Free Software. As usual (for the last 7 years now), the ViGLug organized this event and this time has been in Bernareggio (MB), a city less than half hour drive north-east from Milan. This year, for the first time in the ViGLug life, we have partnered up with other two organizations BrigX (the Bernareggio LUG) and the Coderdojo Brianza.
