Bernhard Findeiss – Kanban or Scrum

Here is a second presentation of our technological IF Forum series

“Self-organization as a Formative Model for Enterpris

Of June, 27th, 2014. It is now accessible for everybody (creative commons).


Many thanks to our speaker Bernhard Findeiss!

I am assuming more presentations will now be made available on a daily basis.
Thanks to: Friedrich (Friedrich Lehn).

On September, 19th, 2013, at 18.00 hours, we of the InterFace AG invite you for another interesting presentation in our “IF Academy” series:

Mailserver & Mail-Client
“History, Basics, Spam&Virusses” or “Concepts for a Private Secure and Reliable Mail Server”.
(Hans Bonfigt / Marc Haber – redoxSystems)

hansbonfigtHans Bonfigt will be our speaker. We are optimistic that his co-author Marc Haber can also come. After the current events and in times of PRISM and Tempora, the timing for this presentation about email and mail in general is just ideal. Consequently, and because we have two of the best experts in the field with us with Hans Bonfigt and Marc, we decided to make a technological IF Forum of this IF Academy event  and invite the extended circle.

Every day, we send and receive many emails. It is our totally normal routine and we might very well often be quite thoughtless about it. The underlying technology seems to be a matter of course, even though, more often than not, it is nowhere near as easy as it looks. Hans Bonfigt will introduce the deep secrets and abysses of email traffic and the underlying technology. Here is his summary:

I will give you a historical introduction to the topic “mail”. You will get to see the roots where rats like spammers, viruses and other parasites feast. Also, I will give a clear differentiation between the terms mail server and mail client. This distinction is important, because a mail client is also among those devices you can host centrally. Eventually, I will show you two operating concepts.

My presentation will be structured as follows: warming-up, basics, introduction (around 20 minutes), actual operating concepts (less than 30 minutes) and live demonstration (10 minutes). This should leave enough time for a discussion.
As always in our IF Forum, we will have our “happy hour” after the discussion. I am quite certain that there will be plenty of exciting material to discuss, especially after this kind of presentation.

About the Speaker:

I first met Hans Bonfigt through the IF blog. Hans is a passionate programmer and IT technologist. He actually learned his craft from scratch and consequently also knows all the “camouflaged” levels of many systems. You will find various articles and comments written by him in the IF blog. They are always straight to the point. He ruthlessly criticizes where the development goes astray and where technology is poorly executed. Also, he points directly towards mistakes frequently made. His outstanding ability is to put things in a nutshell.


As always, the presentation will be held in the seminar zone under the roof of our Unterhaching headquarter building, starting at 18.00 hours. We look forward to welcoming our guests! For registration to this IF Forum, send an E-Mail.

Knowledge and Humour for Computer Scientists

On January, 17th, 2013, the IF-Lab and IF Akademie at InterFace will start a new series of presentations (Vortragsreihe) at Unterhaching.

Thomas Baldus of IF Blueprint AG will be the first speaker at 6 p.m. (in the InterFace building, top floor, teaching area). He will speak about:

APPetite Whetted for Microsoft?!

How exactly does the new taste offensive look as it reaches our shores after its trans-Atlantic voyage?

For more information on the series of lectures, click here: IF-OPEN. Very important – this is not just about the lecture, but also very much about “meeting” during a presentation in the modern format with a “Happy Hour” after the event.

I look forward to a huge audience. Also, I am looking for speakers who would like to share their knowledge and fill the slots on other days. Here is our motto:

From practitioners for practitioners.
Informatics & Beer.

Wikipedia #12 – “Ageing!” or “A German Problem?”

In my last presentation, standing in front of quite an audience, I again asked the question: Who in this room uses Wikipedia? Every finger went up in the air – there was not a single person in the room who does not use it! Wikipedia has grown to be a very important factor. The world can no longer be imagined without Wikipedia.

In Wikipedia, so you would believe, you will find everything. After all, the number of words available in Wikipedia is several times higher than that found in any other encyclopaedia.  Of course, even Wikipedia cannot contain everything. Once in a while, you discover relevant cultural assets that cannot be found in Wikipedia. Basically, it would be our duty as citizens to support the creation of the missing articles.

Wikipedia changes the world. Techniques and terms you cannot find or will only find poorly described will get less and less important. If some innovative concept has not been described in Wikipedia, it will hardly stand a chance of developing into something significant.

Thanks to the democratic structure of Wikipedia, this phenomenon is mostly self-regulative. There is a functioning democratic control mechanism. And, of course, the representatives of all areas of expertise know that their knowledge had better get into Wikipedia if they want to remain relevant. Because technologies and cultures described in Wikipedia, as well as persons and social systems, gain new meaning.

But Wikipedia faces a massive threat!

Is Computer Science a Craft?

In our technical IF forum (fachliches IF-Forum) of June, 24th, at Unterhaching, Thomas Vallon made quite a huge impression on our guests when he asked “Is Computer Science a Craft”?

During his presentation, he described parallels between modern software development and building a cathedral that are quite obvious when you take a closer look. In medieval times, building cathedrals was an exceptional craft. Each cathedral was a true mammoth project with its respective challenges.

Indeed, we discover that there are quite a few things they have in common. Besides, we also discover surprising “philosophical” parallels between our self-perception as software developers and those courageous medieval builders and craftsmen.

For instance, it took a very long time to build a cathedral. Sometimes, this led to different architectural epochs being prevalent while a single building was constructed (for example Gothic and Romanesque). In practice, this meant that a cathedral that was still under construction suddenly looked old-fashioned and badly needed renovation.

Since people believed in agility, they changed plans while they were in the process of building. They also modified, demolished and/or re-built entire sections of a building. There is hardly any cathedral where this was not done.

And through the entire process of “development” (while the cathedral was built), the “operation” (that is the basic function of a Lord’s house) had to continue undisturbed.

Apart from that, many cathedrals also prove in an impressive way what the craftsmen concerned with the edifice considered their “professional honour”. For example, many figures on the facade of Notre Dame have been worked with the same degree of accuracy at the back of the building and high up, although the artist certainly must have known that there was hardly going to be another human who would see it in the near future.
Well, this was only for wetting your appetite. If you want to read something really exciting, here is the manuscript.

Thomas Vallon – Ist die Informatik ein Handwerk?

Do read it!

The background images used during the presentation (designed by Johannes Naumann) are also highly recommendable:

I was particularly moved when Thomas dedicated the presentation to me as a present for my sixtieth birthday.

Thank you, Thomas!

What a pity that we do not have a video or audio tape of the presentation. But maybe we will manage next time!

Open Source Hardware

Recently, I have started to get material from an alumni society:
See Cambridge_University_Computer_Laboratory.
In 1949, EDSAC, the first programmable electronic computer in the world ran there.
When I was one of its 17 students in 1964-65, it was still called “Mathematics Laboratory”.
A sort of Technology Park (silicon fen) has grown up near it.

In the wake of open source software, open source hardware is also becoming important. But, for no good reason, different intellectual property laws apply for it, so that the exact terms of open software licences cannot be applied. Jeremy Bennett wrote about the general situation in The Cambridge Computer Lab Ring. In the spirit of open source, he makes his article available to us. See

Eight Pieces of Advice For Your Popular Blog

5 Top Articles You Yourself are Proud of

Before you go online with a blog, you should have around five articles for starters. Especially during the initial phase of the blog, a high-quality article should go online every day in order to arouse the interest of future readers of the blog. During the initial phase, there are plenty of ideas for articles – which is why you should make a list and structure them well before publication.

Topics the readers are particularly interested in should be further extended. This will be the groundwork for a circle of readers that continues to come back.
