[cip-dev] Use cases behind CIP story

[Agustin Benito Bethencourt]

Hi,

CIP is doing a significant effort to be present in many events to 
explain what are the motivations and goals of the group. The technical 
activity is about to start so there is very little to show and it will 
be the case for some time.

What can we focus on the coming months from the communication point of view?

I think there is a huge value in advertising the use cases that justify 
the commitment from companies like Toshiba, Hitachi and Siemens in CIP.

Some of those use cases are completely unknown for a wide range of 
developers, even many of those who are "Open Source veterans".

By exposing some of the challenges involved in those use cases CIP would 
not just provide a meaningful inside about our environment but also the 
opportunity to have a fruitful conversation with many of those engineers 
who might think that CIP idea of a Super Long Term Support kernel 
(system) is "anti-cultural".

So I would like to encourage CIP main drivers to provide and advertise 
some of those unique use cases. I find them extremely interesting. I 
hope many others will too.

Best Regards

Hi Agustin

I think this is an extremely helpful post.

Why don't we start bring the stories of "Linux in the civil infrastructures
in the world" together, and start a series of blog posts at the CIP website?

If people/companies are willing to contribute the stories, I would be more
than happy to set up a blog section to the CIP web.
I would be very interested in hearing & promoting the use cases regardless
of members and non-members.

Then, we can talk about those stories at the events we are participating in.

regards

Nori

I'd personally prefer to see the discussion start on this list, rather 
than blog posts, since that way people can question, comment and 
discuss.

I'd recommend that blog posts can distill from and summarise the list 
discussion.

Agreed.

If the use cases are so complex that requires a blog or authors want to 
use them internally for marketing/promo, then a blog would be probably 
the best option.

Starting a blog is a big commitment over time though. I would start a 
little smaller using:
* This mailing list, as Paul suggested.
* CIP presentations at events.
** Slides and videos of our talks where the cases are described.

Once we get more robust as project, we can create a blog. Meanwhile, we 
can post the outcome of our presentations and use this mailing list.

I suggest to bring here (mailing list) a couple of cases and getting one 
of them into the ELCE or LinuxCon presentation, for instance, or 
something in this line.

I am planning to show a demo at ELC-E which explains a candidate use case of CIP.
The demo will be a full power plant simulator and controller. In this demo,
Linux runs on all controllers to control plant systems.
The above demo is just an example.

It might be better to provide some typical development and maintenance schedule/process
to explain why CIP is important for civil infrastructure systems.

Best regards,
Yoshi

You just open my appetite for knowing more. If possible, share here some 
info and I will be more than happy to help shaping the presentation to 
make an even bigger hit.

Agree.

There is another aspect that many do not consider when approaching the 
maintenance problem which is risk.

We are very use to nowadays to evaluate maintenance costs. But 
maintenance might involve very high risks in certain environments and 
tackle them might require a heavy investment. This might heavily affect 
the maintenance policies.

I am curious about how Toshiba face this topic for the power plan use 
case you are proposing.

let me try to sketch one example for typical rail automation products:
 - development time of a new system: 3-5 years
 - customer specific adaptions: 2-4 years
 - initial safety certifications / authorization: 1 year
 - safety certifications / authorization for follow-up releases: 3-6 months
   (depending on amount of changes)
 - lifetime today typically 25 years, for some systems up to 50 years

Especially the time (and money) required for the certification for new
releases explains why in general there are no frequent updates.
If new releases are necessary, e.g. because of security reasons the
above mentioned efforts can be drastically reduced by only changing
minor parts (efforts of course vary on type of system and safety level).
Less changes mean less effort. Switching a kernel version is not
considered to be a small change. That's why these products typically
stick to a kernel version for long time which has been tested
extensively in the system environment.

We have similar situations in other domains. Healthcare, for example.
The product lifetimes are shorter, typically 10-15 years. Still there
are certifications (like FDA) which have to be done on system level
which lead to the same problems.

In addition to this there is a general trend that safety critical
functions are more and more implemented in software. This means that the
number of products having those certification need will further increase.

I would also like to state one important point: the super-long-term
maintenance is not a crazy idea by some industry people. It is done
already. Only that it is done behind closed doors by privately
maintained patch-sets. And this is what we would like to change.

Urs
