Welcome to my WebSite.
My name is Mirko Calabrese, aka davenull (or Dave Null) and I was born in Taranto (South Italy) in 20th April 1989 but I live in Genova (Northern Italy).
All the materials that you can find here is protected by free licenses and the’re my personal studies.
You can find all about GNU-Linux, IT-Security, Unix Programming and all the BSD (Berkeley Software Distribution) world (only FreeBSD and NetBSD).
I’m a programmer for the following projects: Debian GNU-Linux, openmediavault, FreeNAS, pfSense, LineageOS (ex Cyanogenmod), OpenWrt, SMF (Simple Machines Forum), WordPress and ATutor.
I’m the founder of FreeNIX Security Labs, Co-Founder of JonixLUG (Taranto Linux User Group), Founder of GenovaLUG (Genova Linux User Group) and system administrator for Fare Zero Maker Fab Lab (Francavilla Fontana, Brindisi, Italy).
I have been doing research in the IT and electronics fields for many years, I deal with teaching and I am both a systems engineer and a programmer.
I also teach english, german and italian for foreign people.
