Welcome back, the next talk will be Jan Kiszka
on Getting more Debian into our civil infrastructure.
Thank you Michael.
So my name is Jan Kiszka,
you may not know me, I'm not a Debian Developer, not a Debian Maintainer.
I'm just an upstream hacker.
I'm working for Siemens
and part of the Linux team there for now 10 years actually,
more than 10 years.
We are supporting our business units in getting Linux into the products successfully
for that long time, even longer actually.
Today, I'm representing a collaborative project that has some relationship
with Debian, and more soon.
First of all, maybe a surprise to some of you,
our civilization is heavily running on Linux and you may now think about
this kind of devices where some kind of Linux inside,
or you may think of the cloud servers running Linux inside.
But actually, this is about devices closer to us.
In all our infrastructure,
there are control systems, there are management systems included
and many many of them run Linux inside.
Maybe if you are traveling with Deutsche Bahn to this event these days,
there was some Linux system on the train as well,
as they were on the ???, so on the control side.
Energy generation.
Power plants, they are also run with Linux
in very interesting ways, in positive ways
Industry automation, the factories, they have control systems inside
and quite a few are running Linux inside.
And also other systems like health care, diagnostic systems.
These big balls up there, they're magnetic resonance imaging systems,
they're running on Linux for over a decade now.
Building automation, not at home but in the professional building area.
Actually, as I said, the train systems are going to be more on Debian soon.
We have Debian for quite a while in power generation.
"We", in this case, Siemens.
We have the box underneath, on the third row,
the industrial switch there is running Debian.
And the health care device is still on Ubuntu, but soon will be Debian as well.
Just to give some examples.
These are the areas where we, as a group, and we, as Siemens, are active.
But there are some problems with this.
Just take an example from a railway system.
Usually, this kind of devices installation, they have a lifetime
of 25, 30 years.
It used to be quite simple with these old devices,
simple in the sense that it was mechanic, it was pretty robust
I was once told that one of these locking systems,
they were basically left in a box out there for 50 years and no one entered the ???
No one touched the whole thing for 50 years
These times are a little bit over.
Nowadays, we have more electronic systems in these systems
and they contain of course software.
What does it mean?
Just to give you an idea, how this kind of development looks like in this domain.
So ???
development takes quite a long time until the product is ready,
3 to 5 years.
Then, in the railway domain, it's mostly about customizing the systems
for specific installations of the railway systems,
not only in Europe, they are kind of messy regarding the differences.
So you have specific requirements of the customer, the railway operators
to adjust these systems for their needs.
And you see by then,
after 5 years already, a Debian version would be out of maintenance and
if you add an other year, you can start over again.
So, in the development time, you may change still the system
but later on, it's getting hard to change the system ???
because then the interesting parts start in this domain, not only in this domain,
that's safety and security assessment and approval for these systems.
And that also takes time.
For example, in Germany, you go for the Eisenbahn ???
and you ask to get a permission to run that train on the track
and if they say "Mmh, not happy with it", you do it over again
and it takes time
and if you change something in the system, it becomes interesting
because some of these certification aspects become invalid,
you have to redo it.
And then of course, these trains on the installation,
the have a long life as I mentioned before.
So how do you deal with this in an electronic device and
in software-driven devices over this long phase?
That our challenge
