Hey friends,

first, thanks for starting this excellent initiaive (we should probably place the texts even
on the "team" part oft he homepage).

I am Julian, 32 years old, married to my lovely wide Constanze and have three kids (two of
them know toddy personally and like him, the third is too small, yet).
We live in Kirchheim which is about 40km south of Stuttgart and at the "Schwäbische Alb"
a very nice and rural area.
I studied math and I really am mathematician by heart. I did my PhD in an applied math project
and worked (together with my fellow Tim) on lithium ion batteries for mobile applications
at a Daimler. But I felt too young and dynamic to stay in a corporate, thus I started a company.

We initially foused on data analysis and BI stuff but moved more and more to technical data
and ended up in the "digitalization" or "Industrie 4.0" world. We joined the PLC4X project
pretty early as we decided to abandon our home made stack to polish PLC4X for our purposes.
Thus, we have it in production since way over a year now and have a lot of hands on experience
(especially Tim). Thus, we often focus on "boring" things like scraper, pools and stability
related stuff (like Netty) and do not so much implement new drivers (AB Ethernet we did together
with Chris). But as we are really deep in the community and love it we do way more in the
project then we would probably need for our business application, solely : )

But generally speaking, you can always ping us with usage scenario questions (mostly Siemens
S7) and integrations. Currently we see ourselves as the main maintainers oft he 0.6 branch
at least until one can migrate safely and stable to 0.7 (when it will be out) as we have too
much stuff in production nowadays to play games (Cesar may surely know what happens when stuff
in production does not work as expected... : D).

So, thanks all of you for making our little community so lovely and enyojable. I feel very
happy tob e part o fit and to hang out with you guys. And we are really making an impact,
more and more!

    I am a research assistant at the University of Stuttgart at the Institute of Control Engineering
(ISW) and work there in the areas of communication/service concepts for automation systems
and cloud manufacturing.
    Among other things with projects like RetroNet I got in contact with several older automation
protocols (ADS, S7, Profinet/bus..) and also more recent ones like OPC UA and their diversity
despite the common goal. That's how I got to know Chris, Julian and the initial PLC4X crew

    Before that I completed a study in software engineering. My main programming language
would be Java, but I already had a lot of stacks in my hands (Javascript, C++, Python, Go,
C#, Ada, PHP).

    I like to sharpen knives and sometimes distil some schnapps. So if someone wants to forget
a bug, you can choose between 40 - 80% alcohol content and 5 flavours ;) If Toddy leaves some.

    At the moment I'm working on the OPC UA integration of Milo into PLC4J with the documentation
(Pls Toddy stop hurting me! ) and a bridge server for the OPC UA representation of other protocols
in an extra integrated OPC UA server. Our institute is quite experienced in TSN and OPC Companion
specifications. Therefore I try to integrate the project into publicly funded research projects
to make PLC4X more known and to support the community.

    Greetings Matthias

    Betreff: [Introduction] Christofer Dutz

    Hi all,

    I have noticed that our tram has grown quite a bit in the last year and most of you I
have never met personally.
    We have been discussing a lot of things here on the list and on slack, but I only have
little background on who you folks actually are.

    So I would like to ask anyone interested to just introduce himself in this thread.

    I’ll start:

    My name is Christofer Dutz, I’m currently 42 years old and studied computer-science
at the University of Darmstadt.
    I’m the son of an Electro-Engineer and therefore already had contact with all of this
automation stuff when I was a kid, but somehow lost contact when I discovered my interest
in computers.

    Being an IT guy living near Frankfurt (Germany) there is almost no chance to not work
for Banks and Insurance companies. So I guess I’ve been working for about 12 different Banks
and Insurance companies in the last 15 years. I always like to compare working for a bank
like asking Picasso to paint a portrait, but to have him wear a mental-institution restraining
jacket and have him paint with a brush in his mouth. End of the first quarter of 2017 it was
getting so unbearable for me, that I was thinking about giving up my profession as an IT specialist
and even starting to learn something new. I was already looking for companies looking for
an apprentice as carpenter, when I had another round of self-reflection. Even if I probably
would have been good as a carpenter, I still love doing my job, just not for Banks and Insurance
    I was seeing the same with a lot of my colleagues.

    It was that time that Industry 4.0 was everywhere … all the problems are easily addressable
with open-source and a lot of the skills I have from the banking would have been a perfect
match. So I had a look at what’s missing in this big picture and pretty quickly noticed
the data-access problem is the biggest barrier and no solution being available or in sight.

    Luckily at codecentric we have something called “Innovation budget”. Here if you’ve
got an idea, you can pitch in some shark-tank-like session with the board and if they like
it, you get the funds for doing that. My idea was to build a universal protocol adapter. From
the beginning I said I want this to be a true open-source project at Apache. The benefit for
codecentric would be to eliminate the barriers to offering IIoT solutions with our large set
of professionals in all areas this involves. The board agreed and for the last 3,5 years I
have been paid by codecentric to work on Apache PLC4X full-time.

    Outside of the IT world, I love to do sports with others, so I’m usually in the gym
in some workout and TaeBo courses about 3 times a week, I love snowboarding and everything
that has anything to do with water.

    Another huge passion of mine is melodic electronic music, so usually I travel around the
Europe visiting different electronic music festivals.

    I live in a town called Ober-Ramstadt together with my girlfriend Tanja, where we just
moved into a house I inherited from my grandpa and which we renovated in 2 years of hard work
… and still the work doesn’t end … so some-times I fall off the face of the earth for
a few days cause I’m probably digging trenches for the foundation for some wall, or my rain-water
system, or … or … or …. Guess the digging never stops.

    Ok … so I hope this gives you a little impression on who I am and what drives me …
it would make me happy to see some of you folks also introduce yourself. And I would even
more love to have a beer with you (Or, as I’m a hessian … a big glass of apple wine) 😉
