Mister Pragmatic Penguin – creating value in a free world
by Matthieu Farcot - CRP Henri Tudor
This is the story of Mister Pragmatic Penguin. This penguin, best known for his pragmatism, surely has a number of idealistic values, but above all, he firmly believes that what is best for him is what is best for his business.
As a short story of the said penguin, this presentation aims at suggesting a few basic clues on how to create value in the framework of free and open source software. It spreads over 3 parts :
- introduction : "let's go fishing",
- when suppliers and consumers converge : "penguins united fare better", and
- a special conclusive guideline : "how to optimize and secure your fishing abilities with intellectual property".
Obviously, this presentation focuses on management and intellectual property issues arising with software (and more specifically in the free and open source fields).
After presenting the most important differences between free, open source and proprietary approaches to software, the main families of software licenses are described. They range from academic licenses, focusing on open knowledge benefits, to reciprocal licenses, designed to create a true common good, and lastly contextual licenses, which tend to be of an academic or reciprocal type according to the context of use.
The purpose of this presentation is to explain to a mostly business oriented audience the differences and impacts of licensing and value management. Since the theme of this « journée du libre » focuses on security, a final guideline is also included on how to make intellectual property developments secure and on value creation with free software, ranging from legal security (ie, licensing interoperability) to software patents (and their backlash). And thus Mister Pragmatic Penguin will have made his point.
About the speaker
Matthieu Farcot is finishing a PhD Thesis in the field of economics of intellectual property at the Beta, Université Louis Pasteur, Strasbourg. He now is an employee of the CRP Henri Tudor.
How Open Source influences our lives
by Machelt Garrels
Conventional IT-people often fear Open Source software, yet it is everywhere around us and the Open culture is sprawling. Most companies, whether they like to admit it or not, nowadays depend a great deal on F/LOSS packages. In this talk we discuss the consequences of openness, from students using Open Source software against the will of their professors to the current blogculture.
Building Open Source Communities
by Robert Viseur - Faculté Polytechnique de Mons / CETIC
The success of an Open Source project is mainly driven by the development of a community able to support the production of software and to ensure its evolvability. Several briefs wrongly contribute the naive vision of software community development, where design does not have its place, contrary to the good sense and the good fortune: "one creates a useful software, one puts it on Sourceforge and that will go well"...
In practice, community development obeys more general rules in accordance with effective management of a co-creation project. Good contributors must be targeted, rights and duties of everyone must be fixed, contribution must be made as easy as possible,... At the software level, architectural design decision and coding rules take all their importance, since the project must sometimes satisfy distant needs and accept various contributions.
This talk will develop the subject of the construction of Open Source communities. It is the result of several years of research on the methodological aspects of the co-development, of an in-depth study of french-speaking Open Source projects as well as the results of a study carried out within the framework of a project of software mutualisation and opening in the Belgian administration.

Open Enterprise Desktop.
by Emmanuel Devaux - Novell s.à r.l. , Luxembourg
Today, enterprises can deploy Linux Desktop with confidence because it is mature.
- From an end-user perspective, new desktop features include easy-to-use interface, simpler menu, integrated search functionality and graphical desktop effects that will forever change the way the users interact with their desktops.
- Besides, Linux Desktop has become more than ever interoperable with existing infrastructures (smooth integration with major directories, email and calendaring systems, and with the most popular file formats).
- From the administrator point of view, hundreds of Linux desktops can now be deployed and managed centrally, which gives a high level of flexibility and productivity.
- Security can be settled with a high degree of granularity, preventing any applications from accessing unauthorised resources.
- Finally, integration of non-Linux applications becomes much easier.
During this talk, most of these concepts will be reviewed and demonstrated.

Using Open Source in a Secure Identity Management project
by Frédéric Girard - CRP Henri Tudor
Secure identity Management is an innovative concept aiming at managing, implementing, maintaining and auditing the Access Control Policy inside an organisation. The Security management is a sensible theme and proprietary solutions are still recently favorite solutions. This is particularly the case when the question is to guaranty confidentiality with information and its treatment. However Open Source solutions can now be preferred with a lot of advantages. Beyond the fact these solutions or their tools are available now, they can provide an equal security level or further.
The project use at first Open Source inside the solution. One of the expected results should be an easiest way for the solution to be adopted by local market in Luxembourg. Indeed such a solution is open and should interest both end-users and IT consulting companies.
We will present our motivations to use precise components, relevant risks, security and quality aspects of the solution. A technical feed-back on which Open Source technologies we used will be presented too. Ending the presentation, a prototype and the main functionalities will be shortly demonstrated to give an idea with what the application should do and look like.

Are Open Source EAI solutions mature for professional use?
by Daniel Kröger and Ortwin Donak - CRP Henri Tudor
Companies and organizations nowadays deploy a large number of heterogeneous systems for common tasks as well as for core business-specific tasks. Along with the growth of the IT-infrastructure the need for system integration is rapidly growing.A plethora of integration solutions with plenty of functionalities is meeting these needs.
Especially for SMEs, these proprietary solutions also come along with some pitfalls like high costs or low support quality. But also larger companies are struggling with vendor dependence or the lack of open standards that put the safety of investment at risk.
The “FreeGate Market Survey of Open Source EAI Software Solutions” explores the maturity of Open Source integration solutions by the application of a staged validation process and evaluates if they already represent a serious alternative for the use in a professional production environment.
In terms of these alternatives the Centre de Recherche Henri Tudor develops together with academician and economical partners an Open Source based solution that is tailored to the information integration needs of SMEs and organizations.

Advancing the Text Interface on texttools interface concepts
by Sven Guckes
Almost every interactive program offers another kind of interface. Some of these you can see in almost every program:
dialogs with many buttons, prompts for texts, menus and submenus - some with keyboard shortcuts for commands.
However, some of them seem to be quite seldom, eg internals command lines, and fast switches.
This is a (small, well, growing) overview to some of these ideas, both with a description and example, either as text or as a screenshot.
Some ideas on interfaces are mostly to be applied for programs running in terminals. this is why I call them "texttools" - in contrast to "graphical tools".
Texttools usually are perceived as outdated programs because of their text interface. But I claim that these tools are here to stay with us for a very long time, if not forever!
Hopefully these ideas will be implemented with more programs - texttools or gui.
Mind you:
This is not about any special programming language.
This is about *concepts*!
