I am responsible for soft- and hardware at this institute. You know, this is a never ending story and full of surprises. Previously I was working as an administrator at university, as a consultant and in an insurance company - mainly in software engineering and implementation. Much of my actual work belongs to genetic projects with the focus on software solutions for scientific questions.

I am very interested in the Unix system FreeBSD and happy that many of our server are running BSD :-) I know *BSD needs in some areas more "hands-on", installation and background knowledge, but the result is a small, functional and stable system. Even on desktops! And it works and works and works!! :) I like this centric (but also community) approach very much and I dislike a (mostly or only) GUI centric system. What about the situation if the GUI does not work? Even I like and use *BSD systems I am not an enemy of others. But I think people, who claim that *BSD does not work, never took time to use it! I made also experiences with Linux, Windows and OsX - and that is the reason why I switched completely to *BSD :) And by the way, there are many (other) interesting operating systems available so far, which are very impressive and definitly worth to check them out - and maybe to switch over :)

FreeBSD	FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
GhostBSD	GhostBSD provides a simple desktop-oriented operating system based on FreeBSD with MATE, OpenRC and OS packages for simplicity. GhostBSD has a selection of commonly used software preinstalled and required to start using it to its full potential.
hello	helloSystem is a desktop system for creators with a focus on simplicity, elegance, and usability. Its design follows the "Less, but better" philosophy. It is intended as a system for "mere mortals", welcoming to switchers from the Mac. FreeBSD is used as the core operating system. Please refer to https://github.com/helloSystem/hello if you would like to learn more about the ideas and principles behind hello.
Ariyx	Airyx is a new open-source desktop operating system that aims to provide a similar experience and compatibiilty with macOS® on x86-64 sytems. It builds on the solid foundations of FreeBSD, existing open source packages in the same space, and new code to fill the gaps. Airyx aims to feel sleek, stable, familiar and intuitive, handle your daily tasks, and provide as much compatibility as possible with the commercial OS that inspired it.
DragonFly BSD	DragonFly belongs to the same class of operating systems as other BSD-derived systems and Linux. It is based on the same UNIX ideals and APIs and shares ancestor code with other BSD operating systems. DragonFly provides an opportunity for the BSD base to grow in an entirely different direction from the one taken in the FreeBSD, NetBSD, and OpenBSD series.
NetBSD	NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
OpenBSD	The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. As an example of the effect OpenBSD has, the popular OpenSSH software comes from OpenBSD.
HAIKU	Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Illumos	illumos is a consolidation of software that forms the core of an Operating System. It includes the kernel, device drivers, core system libraries, and utilities. It is the home of many technologies include ZFS, DTrace, Zones, ctf, FMA, and more. We pride ourselves on having a stable, highly observable, and technologically different system. In addition, illumos traces it roots back through Sun Microsystems to the original releases of UNIX and BSD. see also OmniOS and openindiana.
ArcaOS	Arca Noae brings OS/2 into the 21st Century
MorphOS	MorphOS is a lightweight, highly efficient and flexible media-centric operating system.
MenuetOS	MenuetOS is an operating system for PC, written fully in assembly language (64bit and 32bit). Features include pre-emptive and real-time multitasking with multiprocessor support and Graphical User Interface. Menuet64 is released under License and Menuet32 under GPL. Menuet supports both 64 and 32bit x86 assembly programming for smaller, faster and less resource hungry applications.
ReactOS	Imagine running your favorite Windows applications and drivers in an open-source environment you can trust. That's the mission of ReactOS!
Qubes OS	Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. Qubes OS leverages Xen-based virtualization to allow for the creation and management of isolated compartments called qubes.
Redox	Redox is a Unix-like Operating System written in Rust, aiming to bring the innovations of Rust to a modern microkernel and full set of applications.
OpenVMS	VMS Software, Inc. is migrating OpenVMS and its layered products to the industry standard x86_64 architecture, to help customers protect their investment in OpenVMS infrastructure, especially in virtualized environments and in the cloud. OpenVMS E9.2 is available to all VMS Software, Inc. customers as their valuable feedback will contribute to the quality of the first production release, V9.2.
SerenityOS	SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Chimera Linux	A modern, general-purpose non-GNU Linux distribution. Chimera aims to be a clean and usable general-purpose Linux OS. In order to get there, it tries to liberate itself from the common baggage of most Linux-based systems and do its own thing. Software is sourced from different places and sometimes written from scratch. The FreeBSD tools were chosen for their high quality code and solid feature set. Some source code is also taken from NetBSD and OpenBSD. (nice!! :-))
