Linux Background

I started using Linux back in 2007. My first distribution was SUSE Linux Enterprise Desktop that came preinstalled on a HP notebook. From 2010 I started using Ubuntu on my primary laptop for some time, like four or five years, as a companion to my SUSE box. That was the time I stopped using Windows and never looked back.

I don’t really know why there is all this fuzz around Ubuntu, as I don’t find it to be “the best” there is. For the Desktop, I find Fedora and openSUSE much more interesting and fun to use, even if there is a little more trouble to configure stuff. But hey, this is the fun in using Linux! Debian is also a very nice distro, which I used to use on my desktop for almost a year now.

On my servers I use Debian and CentOS, which are both solid, with CentOS being more secure and suited for enterprise use. CentOS support cycle of 10 years is also a good thing when you plan on using your server for a long time with no major interventions.

Which distro(s) I like most?

Well, I would give my two cents for the rpm based distros like Fedora or CentOS and openSUSE. As I started my journey into the Linux world with SUSE, this distro family will always have a sweet spot in my heart. Fedora, nevertheless is a great distro for workstation, alongside openSUSE Tumbleweed, the rolling release. Using those two distros you will always have the lastest available packages. If I would have to choose between the deb based distros, I would go with Debian Stable all the way. Debian is a great distro, the base for many other highly used distros like Ubuntu or Mint.

Linux training

Some time back I took the Linux Foundation - Introduction to Linux and LFS201 Essentials of System Administration (LFCS) courses using openSUSE as a platform. Now (as of 2018) I am retaking the LFCS course using CentOS7 as a platform. Other courses I was enrolled in from the Linux Foundation are: LFS161 Introduction to DevOps: Transforming and Improving Operations, LFS152 Introduction to OpenStack, LFS158 Introduction to Kubernetes.

On my “to do” list is the LFS171 Blockchain for Business - An Introduction to Hyperledger Technologies. In 2017 I earned a Linux system and server administration certificate from Crystal Mind Academy in Bucharest.

Programming

Prior to my architecture studies, I was a computer science student back in High School, when I learned programming in FoxPro, Pascal, C/C++, Delphi and Visual Basic. Judging by this previous sentence, you can have an ideea about my age. Now I am passionate about Python, C/C++, Qt, HTML/CSS and Bash.

Current professional activities

I am currently a Linux trainer at Crystal Mind Academy and a Lecturer at the University of Architecture and Urban Planning in Bucharest.
