99:59:59,999 --> 99:59:59,999
Welcome back, the next talk will be
Jan Kiszka

2
99:59:59,999 --> 99:59:59,999
on Getting more Debian into our
civil infrastructure.

3
99:59:59,999 --> 99:59:59,999
Thank you Michael.

4
99:59:59,999 --> 99:59:59,999
So my name is Jan Kiszka,

5
99:59:59,999 --> 99:59:59,999
you may not know me, I'm not a Debian
Developer, not a Debian Maintainer.

6
99:59:59,999 --> 99:59:59,999
I'm just an upstream hacker.

7
99:59:59,999 --> 99:59:59,999
I'm working for Siemens

8
99:59:59,999 --> 99:59:59,999
and part of the Linux team there
for now 10 years actually,

9
99:59:59,999 --> 99:59:59,999
more than 10 years.

10
99:59:59,999 --> 99:59:59,999
We are supporting our business units
in getting Linux into the products successfully

11
99:59:59,999 --> 99:59:59,999
for that long time, even longer actually.

12
99:59:59,999 --> 99:59:59,999
Today, I'm representing a collaborative
project that has some relationship

13
99:59:59,999 --> 99:59:59,999
with Debian, and more soon.

14
99:59:59,999 --> 99:59:59,999
First of all, maybe a surprise to some
of you,

15
99:59:59,999 --> 99:59:59,999
our civilization is heavily running on Linux
and you may now think about

16
99:59:59,999 --> 99:59:59,999
this kind of devices where some kind of
Linux inside,

17
99:59:59,999 --> 99:59:59,999
or you may think of the cloud servers
running Linux inside.

18
99:59:59,999 --> 99:59:59,999
But actually, this is about devices closer
to us.

19
99:59:59,999 --> 99:59:59,999
In all our infrastructure,

20
99:59:59,999 --> 99:59:59,999
there are control systems, there are
management systems included

21
99:59:59,999 --> 99:59:59,999
and many many of them run Linux inside.

22
99:59:59,999 --> 99:59:59,999
Maybe if you are traveling with Deutsche
Bahn to this event these days,

23
99:59:59,999 --> 99:59:59,999
there was some Linux system on the train
as well,

24
99:59:59,999 --> 99:59:59,999
as they were on the ???,
so on the control side.

25
99:59:59,999 --> 99:59:59,999
Energy generation.

26
99:59:59,999 --> 99:59:59,999
Power plants, they are also run with Linux

27
99:59:59,999 --> 99:59:59,999
in very interesting ways, in positive ways

28
99:59:59,999 --> 99:59:59,999
Industry automation, the factories, they
have control systems inside

29
99:59:59,999 --> 99:59:59,999
and quite a few are running Linux inside.

30
99:59:59,999 --> 99:59:59,999
And also other systems like health care,
diagnostic systems.

31
99:59:59,999 --> 99:59:59,999
These big balls up there, they're magnetic
resonance imaging systems,

32
99:59:59,999 --> 99:59:59,999
they're running on Linux for over
a decade now.

33
99:59:59,999 --> 99:59:59,999
Building automation, not at home but in
the professional building area.

34
99:59:59,999 --> 99:59:59,999
Actually, as I said, the train systems are
going to be more on Debian soon.

35
99:59:59,999 --> 99:59:59,999
We have Debian for quite a while in
power generation.

36
99:59:59,999 --> 99:59:59,999
"We", in this case, Siemens.

37
99:59:59,999 --> 99:59:59,999
We have the box underneath,
on the third row,

38
99:59:59,999 --> 99:59:59,999
the industrial switch there is running
Debian.

39
99:59:59,999 --> 99:59:59,999
And the health care device is still
on Ubuntu, but soon will be Debian as well.

40
99:59:59,999 --> 99:59:59,999
Just to give some examples.

41
99:59:59,999 --> 99:59:59,999
These are the areas where we, as a group,
and we, as Siemens, are active.

42
99:59:59,999 --> 99:59:59,999
But there are some problems with this.

43
99:59:59,999 --> 99:59:59,999
Just take an example from a railway
system.

44
99:59:59,999 --> 99:59:59,999
Usually, this kind of devices installation,
they have a lifetime

45
99:59:59,999 --> 99:59:59,999
of 25, 30 years.

46
99:59:59,999 --> 99:59:59,999
It used to be quite simple with these
old devices,

47
99:59:59,999 --> 99:59:59,999
simple in the sense that it was mechanic,
it was pretty robust

48
99:59:59,999 --> 99:59:59,999
I was once told that one of these locking
systems,

49
99:59:59,999 --> 99:59:59,999
they were basically left in a box out there
for 50 years and no one entered the ???

50
99:59:59,999 --> 99:59:59,999
No one touched the whole thing for 50 years

51
99:59:59,999 --> 99:59:59,999
These times are a little bit over.

52
99:59:59,999 --> 99:59:59,999
Nowadays, we have more electronic systems
in these systems

53
99:59:59,999 --> 99:59:59,999
and they contain of course software.

54
99:59:59,999 --> 99:59:59,999
What does it mean?

55
99:59:59,999 --> 99:59:59,999
Just to give you an idea, how this kind
of development looks like in this domain.

56
99:59:59,999 --> 99:59:59,999
So ???

57
99:59:59,999 --> 99:59:59,999
development takes quite a long time
until the product is ready,

58
99:59:59,999 --> 99:59:59,999
3 to 5 years.

59
99:59:59,999 --> 99:59:59,999
Then, in the railway domain, it's mostly
about customizing the systems

60
99:59:59,999 --> 99:59:59,999
for specific installations of the railway
systems,

61
99:59:59,999 --> 99:59:59,999
not only in Europe, they are kind of messy
regarding the differences.


62
99:59:59,999 --> 99:59:59,999
So you have specific requirements of the
customer, the railway operators

63
99:59:59,999 --> 99:59:59,999
to adjust these systems for their needs.

64
99:59:59,999 --> 99:59:59,999
And you see by then,

65
99:59:59,999 --> 99:59:59,999
after 5 years already, a Debian version
would be out of maintenance and

66
99:59:59,999 --> 99:59:59,999
if you add an other year, you can start
over again.

67
99:59:59,999 --> 99:59:59,999
So, in the development time, you may
change still the system

68
99:59:59,999 --> 99:59:59,999
but later on, it's getting hard to change
the system ???

69
99:59:59,999 --> 99:59:59,999
because then the interesting parts start
in this domain, not only in this domain,

70
99:59:59,999 --> 99:59:59,999
that's safety and security assessment and
approval for these systems.

71
99:59:59,999 --> 99:59:59,999
And that also takes time.

72
99:59:59,999 --> 99:59:59,999
For example, in Germany, you go for the
Eisenbahn ???

73
99:59:59,999 --> 99:59:59,999
and you ask to get a permission to run
that train on the track

74
99:59:59,999 --> 99:59:59,999
and if they say "Mmh, not happy with it",
you do it over again

75
99:59:59,999 --> 99:59:59,999
and it takes time

76
99:59:59,999 --> 99:59:59,999
and if you change something in the
system, it becomes interesting

77
99:59:59,999 --> 99:59:59,999
because some of these certification
aspects become invalid,

78
99:59:59,999 --> 99:59:59,999
you have to redo it.

79
99:59:59,999 --> 99:59:59,999
And then of course, these trains on
the installation,

80
99:59:59,999 --> 99:59:59,999
the have a long life as I mentioned
before.

81
99:59:59,999 --> 99:59:59,999
So how do you deal with this in
an electronic device and

82
99:59:59,999 --> 99:59:59,999
in software-driven devices over
this long phase?

83
99:59:59,999 --> 99:59:59,999
That our challenge
