NKM et le libre - retour sur la convention System@tic

Hier avait lieu la convention annuelle du P�le System@tic, la deuxi�me depuis la cr�ation du Groupe Th�matique d�di� au logiciel libre.

Nathalie Kosciusko-Morizet, Secr�taire d'Etat � l'Economie num�rique, nous a fait l’honneur d’une longue visite de l’espace exposition, o� �taient pr�sent�s les 9 projets financ�s labellis�s par le GT et les d�mos de deux des projets les plus avanc�s: Scribo et Squale, dans deux des axes technologiques strat�giques du GT: les composants et services pour l’entreprise “3.0” (technologies s�mantiques appliqu�es aux besoins de l’entreprise) et les outils de d�veloppement collaboratifs (en l’occurrence, la qualim�trie).

Lors de son discours (qui m’a touch� par sa spontan�it�), j’ai not� les observations suivantes:

Le logiciel libre est omnipr�sent y compris dans les projets qui ne d�pendent pas de notre GT (plusieurs des projets mis en avant par les autres GT comprenaient aussi une composante logicielle libre) .
Elle estime de ce fait qu’on ne peut plus innover dans le secteur des TIC sans int�grer une part de logiciel libre.
Enfin, concernant les mesures de son plan de relance, elle a observ� que “les mesure les plus simple � mettre en oeuvre sont celles qui ne n�cessitent pas d’arbitrage budg�taire”, autrement dit, priorit� aux propositions qui n'entra�nent pas de besoin de financement nouveau.

Sur ce dernier point, cela m’a fait penser que la majeure partie des propositions que nous mettons en avant en faveur de la “relance par le libre”, par exemple dans le cadre de PLOSS ou dans le cadre de la prochaine �dition de la FLOSS Roadmap, rentrent dans ce cadre (ex: non-discrimination dans les appels d’offres, recommandations claires et actionables sur l’usage des logiciels libres dans l’administration, meilleur alignement des formations sur les besoins de recrutement en sp�cialistes du logiciel libre, des choix clairs en faveur de l’int�rop�rabilit� et des standard ouverts, etc.).

Dicsussion about Enterprise 2.0

Tony Byrne has started a conversation (warning: website is down at present) about Enterprise 2.0 (aka Enterprise Social Software) on CMSWatch.

Here are my comments (waiting for moderation on the CMSWatch site).

Is “Enterprise 2.0” more meaningful than “Social Software”?

“Enterprise 2.0” is more than just social software. I define them with the SLATES and FLATNESS paradigms.

And “Enterprise 2.0” is already pass�. Let’s add semantics in the mix and call it “Enterprise 3.0” ;)
Blogging is pass� — vive micro-blogging?

Blogging is pass� for “hey look at this cool post on this guy’s blog” type of messages. But expressing complex ideas in less than 140 characters is not possible.

So micro-blogging is just another tool of the trade, just as blogging hasn’t replaced mailing list or forums, or IM hasn’t replaced email.

OTOH, I must admit that I’ve been blogging a lot less (and, more importantly, seeing much less blog posts by the people I follow on twitter) since I’ve started twittering.
Can social computing consistently bring real ROI?

In any context where collaboration and knowledge sharing is important, yes.

But “real” meetings and discussions are still relevant, though ;)
Should community managers have to worry about information lifecycle management?

Yes. There is content that you need to control, specially in the face of trolling and other destabilisation attacks.
Are social content ratings really helpful ?

With the right (for the given context) rating algorithm, yes.
Tools: suite or best of breed?

Integration is of paramount importance. World-class open APIs help, a lot, but some features just need to be deeply integrated, at the repository level.
Should your website/intranet have a community or be a community?

Be, of course.
Do you really need an enterprise micro-blogging tool when we have Twitter?

Yes. Most people / corporations don’t want to merge personal and professional lives as the “A-list” twiterers do, and there are obviously confidentiality issues.

Already 10000 views for the Nuxeo DM 5.2 teaser

T�moignage OEM en vid�o - Nel Taurisson (SkinSoft)

J’�tais hier � une pr�sentation de SkinMuseum, application de gestion de collections de mus�es d�velop�es par la jeune entreprise innovante SkinSoft.

Nel Taurisson, responsable de la R&D chez SkinSoft, a accept� de r�pondre � mes question au cours d’une courte interview vid�o que vous trouverez ci-dessous.

Transcription de l’interview

Bonjour, je suis Nel Taurisson, je m’occupe de la R&D chez SkinSoft.

SkinSoft, c’est une soci�t� qui d�veloppe des applications sur la base de Nuxeo. Notre premi�re application est une application de gestion de collections de mus�es. On va ensuite s’orienter vers des applications m�tiers: phototh�que, m�diath�que, biblioth�que.

Ca fait plus d’un an maintenant qu’on travaille en recherche et d�veloppement sur ce sujet. On est parti sur la base de Nuxeo, apr�s avoir regard� de tous les c�t�s ce qu’on pouvait utiliser comme moteur. On est parti sur Nuxeo pour l’architecture de composants, pour l’architecture globale du produit, parce que c’est une plateforme sur laquelle on arrive tr�s bien � d�velopper, et parce qu’il y a une vraie communaut�, qui marche bien, qui r�pond bien.

Voil�, c’est un beau produit et on essaye de faire de beaux produits avec.

Impact du logiciel libre en France sur la formation et les m�tiers de l'informatique - Publication d'une �tude de l'OPIIEC

Syntec Informatique vient de publier un communiqu� de presse synth�tisant les principales conclusions et recommandations de l’�tude “Impact du logiciel libre en France” r�alis�e par Pierre Audoin Conseil (PAC) pour le compte de l’OPIIEC, organisme paritaire charg� d’orienter la politique de formation professionnelle en France dans le secteur de l’informatique.

Cette �tude montre un impact tr�s fort d�s aujourd’hui du logiciel libre sur le secteur de l’informatique, aussi bien dans les soci�t�s de service que chez les �diteurs.

Par exemple:

78% des d�veloppeurs interrog�s utilisent du logiciel libre dans leur entreprise
87% des d�veloppeurs interrog�s pensent que le logiciel libre est une opportunit�.
Plus de la moiti� des soci�t�s interrog�es (directeurs ou responsables des syst�mes d’information) utilisent aujourd’hui des composants libres dans leur syst�me d’information (54% de oui).
Le logiciel libre est vu comme une opportunit� pour l’industrie IT fran�aise. En effet, 88% des personnes interrog�es pensent que le logiciel libre peut prot�ger le d�veloppement de logiciel des d�localisations.

Des recommandations fortes en termes de formations (profils et comp�tences � mettre en avant) pour conserver le leadership de la France dans ce domaines ont �t� propos�es, et valid�es par le Syntec comme par les syndicats.

De plus, les conclusions de cette �tude vont servir � orienter le plan “Editeur SL12” �labor� par le Syntec pour valoriser le m�tier d’�diteur (open source ou non) en France � l’horizon 2012 et qui sera procha�nement pr�sent� formellement par le Syntec. Elles devraient, � mon sens, aider les �diteurs � comprendre comment tirer au mieux parti du virage majeur que repr�sente pour leur m�tier l’utilisation quasi-g�n�ralis�e de technologies et “briques” open sources dans leurs applications m�tiers.

Final sprint before Nuxeo 5.2 (GA)

The final (GA) release of Nuxeo EP 5.2 should be ready in less than a month now. Here are some notes on how we plan to proceed with the final sprint until the release:

you will find below a list of the issues we’d like to address before the release (some of them might already have been addressed).
most of these issues have been affected to teams or developers, who are working on them during this sprint.
so next release, 5.2 RC, is scheduled in two weeks (Friday 27th) and hopefully will be feature-complete (and fairly stable).
the final release will happen after some testing and eventual bugfixing, hopefully less than a couple of weeks later.
the Jira (http://jira.nuxeo.org/browse/NXP) has been updated accordingly (almost, it’s not completely in sync with the list below, we will try a slightly different system when we will start planning the next releases to ensure that the Jira state accurately reflects the products and release backlogs).

Task we must do before GA

Ensure Java 6 compatibility for webservices:

The build will remain in Java 5, but we will support deployment on a 1.6 JVM.
Events:

There are some errors in the logs while processing some events. This seems to only happend for specific events (emptyDocumentModelCreated), but this still needs to be checked and fixed. We should also unit test all async listeners since it’s now possible.
Data Migration:

We need to be able to migrate content from the JCR backend to the new VCS (SQL-based) backend.
WebServices:

We still have the “old” webservice based in JBossWS and JAX-RPC.

These needs to go away :
- there are issues with Java 6
- looks like we can not run JBossWS and Metro in the same box
=> We will migrate the 3 WS (Audit, Core, IndexingGateway) to Metro.
Visible Content Store (aka VCS, aka Visible SQL, aka SQL repository):
- We will support H2, PostgreSQL, MySQL, Oracle, MS-SQL
- All supported DBs must be tested in hudson.
Workflow:
- Workflows needs to be plugged back to the event and notification services.
Annotations: It must be possible to delete an annotation.
Packaging cleanup:

We need to check the packaging :
- remove depracated/compat packages
- remove cache packages

Task we should do before GA

UI cleaup on JSF WebApp:

Some look & feel work will be done by GUnit team.

We will also do some cleanup :
- review order of tabs and namming
- fix / re-enable tooltips
- re-enable D&D inside the browser (it is only 50% usable in M4)
- enable popup context menu on full rows
- refactor summary screen
More FileManager plugins:
- IO-Plugin
- Bundle file mac
- create mail addon
Picture book:
- test, fix and package well
Finish WebWorkspace
REST API:
- Check and document the existing REST API
Update and align sample project on 5.2 GA
Complete / update the Nuxeo Book and the Nuxeo tutorials
Extend audits views:

We can easily provide for each workspace a timeline of what happends. As a default implementation there will be no security filtring on event logs.

Nice to have

Show case for NXThemes and WebWidgets:
- it would be great to have a default usage for WebWidgets
=> use it for the default DashBoard
Mail Drop box:

The idea is to reuse the sceduled email fetcher to feed an InBox associated to each workspace

=> Have an email adresse for each workspace

=> Add a mailto link to workspace summary
NxWSS and MOSS:

Add a WSS URL to each workspace summary to enable direct access via WSS clients.

Dead for GA (will be done in 5.2.1)

GWT integration:

Search Center will be the showcase for GWT integration.
Flex:

We should release the connector and the samples, and communicate how to use them via some blogs.
DynSearch:
- Replaced by Search Center
Thumbs management and nice web folder contents view
Smart Folder / Saved search
UserWorkspace improvements

Video: "10 reasons why Nuxeo is using GlassFish"

"10 reasons why Nuxeo is using GlassFish" presentation

Sun has launched GlassFish Portfolio yesterday.

During the pre-launch press conference in Paris, we’ve been invited by Sun to present how we are integrating GlassFish in our open source ECM technology stack. (Many thanks to Alexis for the invitation).

I outlined the top 10 reasons why GlassFish is a good match to both our open source business model and our technology needs:

10: GlassFish Embedded
9: Provisioning and administration (Update Center)
8: Standard process (JCP), preview of cool technologies (JAX-RS, EJB 3.1 / Java EE 6)
7: Interoperability (ex: Metro)
6: Developers agility (short startup time, scripting support)
5: Documentation, support
4: Reference implementation of the Java EE 5 standard
3: HK2 microkernel (modularity, OSGi, service orientation, dependency injection)
2: Quality, enterprise-readiness, performance and scalability
1: Momentum, open source community

The Slides are here:

CMIS Update

Florent Guillaume is in the US this week for the first face-to-face meeting of the CMIS working group since the project got accepted by OASIS a few months ago. We’ll get a clearer roadmap for the specification (which, last time I checked, was supposed to go gold by the end of 2009 or beginning of 2010).

A prototype miminal implementation of CMIS 0.5 (the most recent draft) on top of WebEngine, using all the power of JAX-RS annotations, is now publicly available (http://hg.nuxeo.org/sandbox/nuxeo-cmis/).

R&D work on the semantic web

Work has started on two large scale R&D projects, financed in part by the French Government and Paris Region (for Scribo), and by the European Commission (for IKS).

Scribo (http://www.scribo.ws/xwiki/bin/view/Main/WebHome) aims at integrating language and image analysis technologies, as well as ontologies extractions and annotation techniques, into content management systems. Work on the project is now in the design phase, but expect to see some code related the UIMA (http://en.wikipedia.org/wiki/UIMA) in our repository in the following moths.
IKS (http://www.iks-project.eu/) is a 4 year project funded by a 6.5 MEUR grant from the EC which aims to bridge the gap between researchers in the area of semantics and interactive knowledge, and small to medium size companies in the fields of Content Management and Knowledge Management. Its end major technological result of the project will be the “Interactive Knowledge Stack”, a layered set of software components and specifications which will make traditional content management platforms capable of dealing with the future “Semantic Web”.

Upcoming Release

We’re still working very hard on the 5.2 M4, which has been delayed one more week and should be ready by the end of this week.

Here are a few technical highlights of what’s coming soon:

The SQL repository will become the default repository in 5.2 (JCR storage will still be supported).
Workflow refactoring: the workflow API and implementation is being simplified, to be easier to use for developers.
Events refactoring: the event API and implementation is being simplified, to be easier to use for developers.
WebEngine: some refactoring to make it easier to use for developers (see a pattern here ;) ? ) Another huge improvement is that it is now possible to write the interaction classes in Java and have them hot-releaded by the server, increasing developers agility and pleasure.
Search refactoring: the Core is now responsible for search, the API has been simplified, Compass is gone.
A new “Converter” API that replaces the existing “Transformer” API, for content transformation.
GWT support.
Lots of other improvements, and new features, that will be presented in more details in the release notes.

Video, slides and transcript of my talk at the Nuxeo DevDay

My keynote presentation at the Nuxeo DevDay last Monday was called “The Nuxeo Way: using open source to build a world-class open source ECM platform”. It was very enjoyable for me both to introduce the conference and to reflect on the first 8 years of Nuxeo.

The conference itself was for us a real success (the room was packed), and according to the feedback we got from the participants, everyone enjoyed the experience.

You will find below the slides, the video and a transcript of my talk.

Transcript

A bit of history

Our company was started eight years ago, in 2000, and from 2002 to 2005 our product line was based on Zope. During that time, we learned quite a lot about ECM, open source, and how to build a proper architecture.

In 2005, we started to introduce Java technologies in our offering. We first did a very interesting project, based on Eclipse RCP. At the same time, we started an hybrid prototype mixing Zope and Java technologies. It actually did work out, but we quickly realized while doing this project that it was even better to switch completely to Java.

So, since 2006, we are fully Java based, and we don’t have plans to switch to another technology in the foreseeable future.

Goals and vision

Our original goal for the Nuxeo projects was to address the full scope of ECM applications.

Since we had to initially focus our resources on a smaller subset of this scope, we decided to start first by focussing on document management.

For these two reasons, we wanted an architecture that would be highly extensible so that we could easily add new modules to implement new functions over the lifetime of the project. We also wanted to make it easy for other people or companies to add their own value on top of the platform, hence enabling and sustaining the creation of a real ecosystem around the Nuxeo platform.

The technical vision to reach these goals was to build the platform on solid existing foundations instead of reinventing the wheel: standards (such as the JCR then, or now JCR2 or CMIS), and open source libraries and frameworks.

This is the real benefit of open source: to reuse what other people have built, and provide your own value, as new frameworks and components, on top of it.

During our journey from Zope to Java, we learned some very important lessons:

From the Zope era, we learned the value of component architectures and the basics of the ECM discipline. These are lessons, of course, that we remembered when designing the architecture of Nuxeo EP.
From the early RCP project, we learned about OSGi and extension points, which are now the foundation of our component architecture.
During the Java era, we experienced the value of standards. They are important, because they make it easier for partners such as systems integrators or ISVs to adopt our technology. We also learned that with the proper tools (such as a good IDE) and architecture, we can be as productive with Java as we were with Python, and provide better quality.

Process and tools

We also wanted to implement a robust software engineering process, with a strong focus on quality, and to make it transparent to our customers and to the community, to make it easier for you to participate in this process.

We also have an internal goal for this process, which is to improve collaboration between teams that are involved in working in custom projects for our clients, and those who work on the generic open source platform.

We started out early in the life on the company by adopting development practices from extreme programming (XP) and test-driven development (TDD). We found over time that it was needed to complement these practices with a discipline for project management that would be simple and easy to use, that would increase team efficiency and productivity, and that would be able to scale up, as our company is growing at a very fast pace (> 50% / year).

So we decided this year to introduce the Scrum development methodology, as it is the most popular and best documented agile methodology now, and that literature shows that it is really helpful in increasing productivity, quality and control over development schedules.

Of course, we are still using TDD with open source tools, such as JUnit for unit tests, Selenium for functional tests, and Hudson for continuous integration, that continuously monitor the quality of our products.

Other tools was are using now are also open source, with a few exceptions: Mercurial, which was introduced this year, for distributed source management (we believe this approach scales much better than the centralized SCM provided by Subversion); Maven, to manage dependencies, build, packaging and releases (it is a bit complex but very powerful and is quickly gaining acceptance in the Java development community); Jira, a non-open source task and issues management system, that helps us implementing the Scrum process.

Where do we go now?

Our work on the platform is driven first by evolving or emerging market needs, such as “enterprise 2.0”-style collaboration, mobility or moving storage and computing infrastructure to the cloud, etc.

We also listen a lot to developers feedback. We conducted a first developer survey last month, and got an overall satisfaction index of 3.8/5, which is already very good.

Here are a few more important facts discovered by this survey:

The strongest points of our platform, according to you: ease of installation, a large set of functionalities, and strong standards supports. As you remember, these were some of the main goals for us when designing the platform.
There are however areas for improvement, which we are working on now, mostly: usability and design for the default user interface, and documentation.
All of you are interested in Document Management and Search, and you also have strong interest in Records Management, Collaboration and Workflow.
From the technical side, you think our strongest points are our initial choice of technologies, our conceptual model, our architecture and our API. On the other hand, we need to work a little bit more on ease and speed of development, for instance by providing more tools for this, and, as I already said, on developers documentation.
According to the poll, your preferred deployment platforms for the server applications are open source Java EE application server: JBoss (81%) and GlassFish (64%), but also “lightweight” web containers such as Jetty (45%) or Tomcat (40%).
Your preferred DBMS are PostgreSQL over MySQL (83% vs. 56%), among open source options, and Oracle over MS-SQL (37% vs. 15%), for proprietary systems.

How can you get more involved?

The open source game goes two ways. We’re working very hard to provide you with the best possible open source ECM platform, but we also need your input on several points.

First of all, you can test the platform, and fill bug reports and requests for enhancements on the Jira.

You can discuss with us new APIs or other improvements to the platform, using the mailing list, the forum, the wiki or the Jira.

You can help us write better documentation, either by writing self-contained pieces of advice in the FAQs and HOWTOs, or by editing the Nuxeo Book or other bits of official documentation.

You can also create new translations. There are already 7 or 8 existing translations, and you can easily create a new one by translating a property file.

Of course, you can get involved in the coding side of the project by becoming a committer to the code base: fixing bugs, improving existing code or adding new functionalities.

The best way for you to become a committer is first to create patches and upload them to the Jira. Of course, these patches need to adhere to the Nuxeo coding standard, and will be reviewed by more senior committers before being actually committed to our code base.

If everything goes well, after a few accepted patches, you will get full access to the source code repository.

You can also work on your own side. Because it’s an open and extensible platform, you can own a bit of functionality and develop it on your own terms.

So, with our plugin architecture, you’ve got the choice: you can either work on your own forge or SVN, or we can host your project on our development environment.

Conclusion

Once again, thank you.

Thank you for coming to this conference, all 60 of you.

Thank you for everything you have contributed so far to the platform.

And thank you for your attention.

R�action � la publication du plan Besson "France Num�rique 2012"

Le plan “France num�rique 2012” pr�sent� hier par Eric Besson fait l’impasse sur le secteur du logiciel. Seules 3 mesures sur 154 concernent le secteur du logiciel (hors jeu vid�o), et ne r�pondent pas de mani�re significative aux attentes du secteur. En particulier, on ne peut que d�plorer l’impasse qui a �t� faite sur les propositions du rapport Attali en faveur du logiciel libre.

C’est d’autant plus regrettable que le plan note que “le logiciel libre repr�sente un potentiel �conomique et industriel consid�rable” et que “la France dispose dans ce domaine d’atouts reconnus aux niveaux europ�en et international” (notons que plusieurs cabinets d’analyse am�ricains ont not� cet �t� que la France �tait “championne du monde” dans ce secteur).

D�taillons les trois mesures concernant le logiciel dans le Plan Besson:

L’action 63, “Cr�er un r�seau “Logiciel” de correspondants dans au moins dix villes cl�s de l’industrie du logiciel, en parall�le du r�seau “TIC” d’Ubifrance” vise, et c’est un objectif l�gitime, � favoriser la capacit� d’exportation des �diteurs de logiciels fran�ais. N�anmoins, elle reste � un niveau relativement symbolique, et l’on peut m�me s’interroger sur l’int�r�t d’avoir un r�seau “logiciel” s�par� du r�seau “TIC”, tant les acteurs de l’informatique (�diteurs et soci�t�s de services, notamment) constituent un �cosyst�me qui doit travailler de concert pour gagner des parts de march�s.
Les actions 64 et 65, “Promouvoir un affichage s�par� des prix des logiciels et syst�mes d’exploitation pr�-install�s” et “Permettre la vente d�coupl�e de l’ordinateur et de son logiciel d’exploitation”, sont des revendications de longue date du groupe “D�taxe Windows” lanc� par Roberto Di Cosmo en 1998, et plus g�n�ralement de la communaut� du logiciel libre et de ses principales associations. Elles permettront d’acc�l�rer la diffusion de syst�mes d’exploitation libres comme Linux aupr�s d’un public de connaisseurs, sans avoir cependant d’impact significatif sur le grand public qui lui d�couvrira plut�t Linux et l’univers des logiciels libres grand public via les Netbook.

Surtout, ces deux derni�res mesures ne concernent qu’un domaine sp�cifique du logiciel, celui des syst�mes d’exploitation, et n’aident en rien les �diteurs de logiciels applicatifs, qui r�alisent pourtant l’essentiel du chiffre d’affaires du secteur.

En tant que fondateur d’un des deux leaders fran�ais de l’�dition de logiciels libres, je suis donc d��u par le plan pr�sent� par M. Besson, et je m’associe aux diff�rentes demandes des organisations repr�sentatives du secteur pour que des mesures plus sp�cifiques, en faveur du secteur du logiciel en g�n�ral et du logiciel libre en particulier, soient annonc�es rapidement. Des recommandations d’achats claires en direction de l’administration, exigeant le respect de v�ritables standards ouverts et interop�rables, et favorisant les logiciels libres � qualit� et co�t �gal � leurs �quivalents propri�taires, font ainsi partie des mesures que le gouvernement devrait prendre en priorit�.

Je note enfin que dans le contexte de crise �conomique actuel, le logiciel libre constitue une r�ponse �conomiquement pertinente aux r�ductions de budgets qui menacent les services informatiques dans les entreprises et les administrations, qui pourront ainsi poursuivre leurs investissements en faveur de la r�activit� et de la productivit�. Face � la crise qui est son soucis principal actuellement, le Gouvernement ne pourra que reconna�tre les atouts du logiciel libre dans ce contexte et prendre les mesures naturelles qui assureront la meilleure comp�titivit� possible aux entreprises fran�aises.

Program for Nuxeo Dev Day (Paris, 1st Dec.) is now online

I’m happy to report that we’ve finished setting up the conference program for the first Nuxeo Developer Day in Paris, which will take place on 1st December, as a “community session” during the awesome Open World Forum.

The conference will be a unique opportunity for you to meet and discuss with the Nuxeo core developers, and to exchange your experiences as users of the framework with fellow Nuxeo applications developers.

Only caveat: there are a limited number of available seats (50) and if you intend to attend (attendance is free, BTW), we ask you to say so by sending a mail to devday@nuxeo.com.

First European Nuxeo Developer Day - Dec. 1 2008

I’m pleased to announce that we are organizing, with the help of several other people, the first “big event” in the Nuxeo Community: the Nuxeo Developer Day.

It will take place during the “Open World Forum” event in Paris, on Dec. 1 2008.

The program is still under construction, but in any case I can promise it will be intense and will please even the most hardcore developers.

Here are some highlights:

What’s new in Nuxeo 5.2 (codenamed “Chicago”)
Roadmap for 2009 and beyond
Interoperability (including the emerging CMIS standard)
Several case studies from all across Europe (Spain, Sweden, UK…)
Technical talks about just about everything that is new or cool in Nuxeo 5.2:
- The new Nuxeo Core / SQL repository
- OpenSocial integration
- WebEngine
- RIA frontends (Flex, GWT…)
- Glassfish integration
- Nuxeo Runtime and OSGi
- Nuxeo RCP
- Mobile applications w/ Nuxeo
- Semantic applications

All the talks will be given in English.

Attendance is free. Even lunch will be provided by the organizers ;)

However, as there are only a limited number of seats (50) in the room, we ask that you to register before the event (preferably ASAP).

You can do so by just sending me an email (sf@nuxeo.com).

Or by registering on Facebook if you have an account there (you may also want to join the Nuxeo User Group on Facebook).

Note that the Open World Forum lasts for 2 days (see the full program), so if you’re coming from far away, and are interested in the politics or economics of open source and innovation in Europe, you may also want to stay in Paris for the second day (Dec. 2).

First Release of Nuxeo WebEngine

WebEngine is a lightweight, versatile, content-centric, open source web framework to quickly build and deliver next generation content-oriented web applications.

WebEngine relies on the Nuxeo content infrastructure (OSGi runtime, component architecture, document repository, ECM services, etc.) to provide a component-based programing model and a web development model for building componentized content-centric applications (such as wikis, blogs, content-oriented websites, etc.).

WebEngine relies heavily on the REST paradigm: URLs are mapped to the hierarchical content repository, content is accessed using GETs, user actions are GETs and POSTs, etc. Hence it’s very easy and straightforward to write RESTful apps using WebEngine.

WebEngine is fully extensible and componentized, thanks to OSGi (all components are OSGi bundles) and Nuxeo Runtime’s extension points.

WebEngine can run either standalone (with startup time <4s) using the Nuxeo Runtime launcher and the embedded Jetty 6, or in a full-blown Java EE app server such as JBoss. WebEngine can also be connected to any Nuxeo EP instance (and Nuxeo Core repository) and be used to expose / publish its content to the web.

Hope you’ll enjoy it. There are some more in the works.

Nuxeo EP 5.1.3.2 released

We have released Nuxeo EP 5.1.3.2 earlier this week. This is a maintenance release primarily focussed on bug fixes and small improvements.

You can download it as

a multi-platform installer

or:

a simple ZIP for headless installation

The changelog for this release is available.

Minor, but anyway noteworthy improvements include:

Nuxeo EP now works on a Java 6 JVM, which can lead to significant performance improvements (up to 100% for certain workloads, according to some internal benchmarks).
Full text indexing has been improved and made faster.
Some tweaks have been done to enable communication with the new (soon to be released and announced) “LiveEdit” plugin for Internet Explorer, Firefox and MS-Word.

Interview on ComputerWorld UK

I've been interviewed by Glyn Moody, one of the best journalists covering open source, for the ComputerWorld UK web site.

France is not a country many would associate with free software startups, but that's changing – not least because the French government is showing itself far more receptive to open source than its UK counterpart. One of the leading companies of this new Nouvelle Vague is Nuxeo, which was set up by Stefane Fermigier, now its CEO.

Nuxeo EP 5.1.3 and 5.1.3.1 released

Nuxeo EP 5.1.3 has been released in January, with 235 enhancements over the previous version, Nuxeo EP 5.1.2, which had been released in October.

A bugfix release (5.1.3.1) was also done a few weeks after with 20 bugfixes and enhancements.

Download it now (107 Mb).

Upcoming Nuxeo 5.1.3 release + Updated roadmap

The Nuxeo EP 5.1.3 release is coming along nicely after a small delay due to the holiday break, and will be tagged in a couple of days.

The roadmap for the project in 2008 has been updated accordingly.

Feel free to discuss it in the mailing list or the forum if you have questions, suggestions or to supply missing information.

As can be seen, Nuxeo 5.1.3 will not be just a maintenance release, as we’ve been able to add new features by creating new plugins (ex: WebDAV, Portlets, SSO, etc.) thanks to a now quite stable infrastructure and API.

Nuxeo 5.1.3 will also be based on Nuxeo Runtime and Core 1.4, which feature some improvements while staying compatible with the previous version (1.3). The switch to Nuxeo Core 1.4 was done in December and has proved very stable.

After the 5.1.3 release, we’re going to focus on the 5.2 (trunk) work, so as to move to Seam 2 for the web platform. Most new features will still be developed as new components, and will either be delivered with the next maintenance release (Nuxeo 5.1.4) or with Nuxeo 5.2, or both, depending on technical feasibility and customers needs or community contributions.

Nuxeo 5.1 RC released - GA release scheduled for next week

We have been so busy the last couple of months working on customers projects that the 5.1 release has slipped a bit, but I’m happy to report that we have just released Nuxeo 5.1 RC.

The final release (Nuxeo 5.1.0.GA) will be made next week, and then we’ll spend the rest of August:

finishing and polishing the Nuxeo Book.
planning and starting the next iteration of Nuxeo (5.2, cf. the current roadmap).
Working on new customers projects (including some that feature the Apogee Project which has already seen a recent surge of activity).
getting some holidays :)

Interview rat�e du Debian Project Leader dans Le Monde

Le quotidien Le Monde a r�cemment fait para�tre une interview du “Debian Project Leader”, Samuel Hocevar. La lecture de cette interview m’a passablement agac�, car d’une part elle propage � mon sens un certain nombre d’id�es re�ues sur le libre (“logiciels d’informaticiens pour informaticiens”) plut�t que d’en faire la promotion aupr�s d’un public assez large, et d’autre part elle s’attache plus � faire la promotion de Wikipedia que du logiciel libre.

Plut�t que de critiquer point par point les r�ponses de Samuel aux questions du journalistes, j’ai pr�f�r� refaire mes propres r�ponses � ces m�me questions.

Que pensez-vous du succ�s grandissant des logiciels Firefox ou OpenOffice ?

Le navigateur web Firefox et la suite bureautique OpenOffice.org partagent un certain nombre de caract�ristiques qui expliquent leur succ�s actuel, aupr�s du grand public et de certaines administrations ou entreprises:

Ce sont des logiciels qui r�pondent aux deux principaux besoins g�n�riques des utilisateurs d’informatique: l’acc�s au Web et la bureautique.
Ce sont des logiciels multi-plateformes: ils tournent � la fois sous Windows (qui reste la plateforme dominante du march�), sous Mac OS et sous Linux.
Ce sont des projets matures: Firefox est issu de la base de code du navigateur Netscape d�velopp�e dans les ann�es 90, OpenOffice.org de la suite StarOffice dont le d�veloppement a d�marr� en 1994.
De plus, il s’agit de projets qui disposent d’une force de travail importante, constitu�e en partie de personnel d’acteurs majeurs de l’informatique (IBM, Google, Sun, Novell…) qui ont un int�r�t strat�gique � contrer l’h�g�monie de Microsoft sur le poste de travail.
Il y a un lien tr�s fort entre ces deux logiciels et les standards ouverts sous-jacents: les standards du Web pour Firefox, le standard ISO Open Document Format pour OpenOffice.org. La lutte de lobbying intense � laquelle Microsoft se livre depuis plus d’un an pour faire normaliser son propre standard “Open XML” aupr�s de l’ISO (en d�pit du bon sens: pourquoi cr�er une deuxi�me norme alors qu’il en existe d�j� une?) et selon des m�thodes peu consensuelles montre l’importance strat�gique des standards dans l’informatique actuelle.

Il faut noter cependant une diff�rence importante: le principal concurrent de Firefox est Internet Explorer (et, dans une moindre mesure, sur plateformes Mac OS, Safari) qui est int�gr� comme navigateur par d�faut dans les syst�mes Windows de Microsoft, donc vu comme gratuit par les utilisateurs, alors qu’OpenOffice.org se positionne principalement face � la suite Office de Microsoft, qui est on�reuse:

Pour arriver � convaincre une proportion significative d’utilisateurs d’installer Firefox plut�t que le navigateur par d�faut, les d�veloppeurs de Mozilla doivent se diff�rencier par la qualit� et les fonctionnalit�s de leur produit. Ainsi, face � Microsoft qui, une fois qu’il a cru avoir gagn� la “guerre des navigateurs” face � Netscape au d�but des ann�es 2000, a cess� toute innovation sur son navigateur, Mozilla a introduit des dizaines d’innovations comme par exemple la navigation par onglets ou les bloqueurs de popups, innovations pl�biscit�es par les utilisateurs � tel point que Microsoft a �t� oblig� de les copier dans IE 7.
Dans le cas d’OpenOffice.org, la diff�renciation se fait le plus souvent par le prix: la suite Office 2007 de Microsoft co�te, typiquement pour une PME, de 500 � 950 euros par poste, ce qui est du m�me ordre de grandeur que le prix d’un ordinateur bureautique d’entr�e voire de milieu de gamme. C’est un co�t important qui rend tentante l’offre gratuite d’OpenOffice.org.

Justement, comment voyez-vous l’avenir des logiciels libres grand public ?

Le succ�s de logiciels comme Firefox, OpenOffice.org ou VLC (logiciel de lecture vid�o lui aussi multi-plateformes) montrent que des logiciels clefs, qui peuvent repr�senter jusqu’� 80 ou 90% de l’utilisation quotidienne de l’informatique par un grand nombre d’utilisateurs, peuvent �tre des logiciels libres.

Ce succ�s d’un petit nombre de logiciels g�n�ralistes, et d’une “longue tra�ne” de logiciels plus sp�cialis�s, sur des plateformes comme Windows et Mac OS, permet d’�duquer le grand public sur l’existence et la qualit� des logiciels libres, et peut en amener un certain nombre � vouloir �galement s’int�resser � Linux en tant que syst�me d’exploitation pour postes de travail. Les principaux �diteurs de syst�mes d’exploitations bas�s sur Linux - Red Hat, Novell, Mandriva, Ubuntu - constatent actuellement une demande du grand public, et de la grande distribution, sur ce secteur, et plusieurs indices, dont le “flop” du lancement de Vista, laissent � penser que 2008 sera l’ann�e du d�collage de Linux aupr�s d’une partie du grand public.

Signalons par ailleurs un autre facteur de diffusion des logiciels libre: le logiciels embarqu�s dans du mat�riel sp�cialis�. En France, la Freebox, la NeufBox et de nombreuses autres “appliances” int�grent d�ja depuis plusieurs ann�es un noyau Linux et de nombreux logiciels libres. Dans les pays �mergents, des initiatives comme le One Laptop Per Child sont �galement une fa�on de diffuser des logiciels libres aupr�s de millions d’utisateurs, qui ne connaissent pas Windows et qui sont donc vierges de tout a priori.

De plus en plus d’entreprises priv�es et d’administrations passent aux logiciels libres, d�sormais consid�r�s comme des “concurrents” par Microsoft. Existe-t-il encore des freins � leur g�n�ralisation ?

Dans le domaine des logiciels d’entreprises, la donne est tr�s diff�rentes: il n’y a pas un seul acteur qui domine outrageusement le march�, mais plusieurs acteurs dominants: Microsoft certes, mais aussi SAP, IBM, Oracle, EMC, etc.

Sur ce secteur, et principalement dans le domaine des logiciels serveurs, d’abord au niveau des logiciels d’infrastructure (communication, bases de donn�es, monitoring, etc.) et progressivement au niveau des logiciels applicatifs (CRM, ERP, GED, ECM, etc.) les logiciels libre se sont dans certains cas d�ja impos�s (ex: Apache) et dans la plupart des autres, connaissent une progression rapide.

Un frein notable � cette progression est l’ensemble des pratiques anti-concurrentielles de Microsoft, d�nonc�es par l’ensemble de l’industrie, et qui lui ont valu de tr�s nombreux proc�s et un certain nombre de condamnations.

A part cela, il est plus appropri� de parler d’inertie que de freins, car il s’agit de faire changer les mentalit�s des d�cisionnaires, de former les informaticiens de terrain, et de remplacer des investissements qui s’amortissent sur de 5 � 10 ans.

Une chose est claire pour toute le monde cependant: le logiciel libre a chang� la fa�on dont les logiciels sont d�velopp�s par les �diteurs. Ceux-ci se reposent de plus en plus (31% en 2006, probablement plus de 50% en 2007 ou 2008) sur des “briques” logicielles libres, mais aussi “ouvrent” de plus en plus leur mod�les de d�veloppement. D’ici 5 ans, je suis certain que la plupart des �diteurs de logiciels d’entreprises auront int�gr�, d’une fa�on ou d’une autre, une partie des m�thodes du libre dans leurs d�veloppement.

Comment voyez-vous l’�volution de la distribution de contenus culturels ?

On est dans un cas d’�cole d’innovation disruptive, selon le mod�le de Clayton Christensen:

Les anciens acteurs dominants, les “majors”, s’accrochent � leur ancien mod�le � pr�sent obsol�te et militent pour des l�gislation drastiques dans ce domaine.
Une partie du public � trop rapidement adopt� les pratiques d’�change en pair � pair ou sur des sites de mise en ligne de contenus, sans int�grer les limites l�gales et morales de leurs pratiques: �changer des contenus libre et contribuer de mani�re communautaire � leur d�veloppement, c’est bien; �changer des contenus soumis � des restrictions d’usage en dehors du droit � la copie priv�e, c’est mal.
Les pouvoir publics, faute d’une vision claire sur ce dossier, et sous l’influence des lobbies du pass�, ont vot� des lois tr�s dures (DADVSI) visant � maintenir le statu quo.
Un petit nombre d’acteurs, � commencer par Apple, a saisi au moment opportun la rupture technologique et s’en est servi pour reconfigurer la cha�ne de valeur de la diffusion des contenus autour de leur offre de produits (ex: l’iPod) et de services (ex: iTunes), r�alisant ainsi le “hold-up du si�cle” sur l’industrie musicale, et bient�t sur l’industrie cin�matographique.

A mon sens, l’un des r�le majeurs d’un projet comme Wikipedia, qui montre la force mais aussi les limites du mod�le de d�veloppement coop�ratif, est d’�duquer le public sur ces questions de production communautaire de contenu et sur les questions de droits d’usage des contenus, de montrer qu’il y a plusieurs mod�les possibles, chacun avec ses forces, ses faiblesses et ses tabous, et qu’il est important de les conna�tre pour se comporter de mani�re citoyenne.

JavaOne Nuxeo Slides: now in original format

The slides of our presentation at JavaOne have now been published by Sun (minus an URL error from this page which I hope they will correct soon).

Now that Sun has made them public, I have uploaded them to SlideShare, where they are available alongside other presentations tagged “javaone”.

Are Nuxeo's open source projects truly community-driven? You bet they are!

Dion Almaer wrote yesterday a blog entry with a list of criteria that, in his opinion, make an open source project truly community-driven (which is, of course, a Good Thing(tm)).

I had some apprehension, while reading the blog entry’s title, because, of course, we want to be community-driven (that’s one of the criteria BTW), but what if we had forgotten something important?

Fortunately, the short answer is “of course we are community-driven”. With Dion’s criteria, I can confidently self-grade us at A+ (or 20/20, for french-educated people). Here are the criteria and my comments:

If you don’t have any commiters from outside of your company. You probably aren’t community driven.

Half of the commiters in the Nuxeo project are not Nuxeo employees, and we are actively trying to recruit more contributors.

If you didn’t spend time cleaning up documentation for the community when you opened it up. You probably aren’t community driven.

We’ve produced already several hundreds of pages of users and developers documentation, and we’ve gone through great efforts in producing this documentation in time for the first public releases of the software.

If your users haven’t helped with the documentation if it is lacking. You probably aren’t community driven.

We got great feedback from our users regarding the documentation, and we’ve already had user-contributed sections in some of our manuals.

If you do not have some kind of forums/lists where people help each other out. You probably aren’t community driven.

We have several mailing lists for all of our projects, with a total of about 1500 subscribers.

If you aren’t willing to put in a lot of effort to build your community to get true benefits. You probably aren’t community driven.

Yes, we’re putting a lot of efforts, and we get the rewards of course.

But there is something more important, that is not explicitly stated in Dion’s criteria: we have designed the Nuxeo software with the explicit goal of creating an Architecture of Participation (a term coined by Tim O’Reilly, Dion’s boss, BTW). Our creation of Nuxeo Runtime, the OSGi-based plugin system (inspired by Eclipse’s), our use of a component framework like JBoss Seam for our webapp, are consequences of this vision, which comes from years of experience working with system integrators and ISV.

Extensibility at all levels is one of the majors criteria of a successful historical open source project (think Eclipse’s or Mozilla’s plugins, Emacs scripts, LaTeX packages, etc.). Monolithic apps usually don’t make great open source communities. That’s a lesson we will never forget!

Back from BrainCamp Ouverture 2007

As some people know already, I have participated in the creation of Ouverture (n� “Open Source Valley”), the Competitiveness cluster dedicated to Free and Open Source Software in the Paris area.

We are still waiting for the official stamp of the French Government, which will start the operational life of the cluster by bringing Government funding to R&D projects carried out by the cluster’s members: public research labs, universities and companies. Since there seems to be some, let’s say “bureaucratic delays”, we had decided to start some activities that don’t depend on the official stamp, namely bringing together all the cluster’s participants to brainstorm ideas for projects that would be later submitted to the cluster.

This first event was christened “BrainCamp 2007” and happened today at ENSTA, a Parisian engineering school that has been a pionneer in the use of open source software in higher education in France.

Like every SME that participated in this BrainCamp, I had 5 minutes to present Nuxeo to the other participants: about 15 research labs, 20 SMEs (including the biggest names in the French open source market: Mandriva, Idealx, Linagora, XWiki, etc.) and 4 big companies (which happen, can you believe it, to be all partners of Nuxeo: Capgemini, Unilog, CS, Sun).

My point was to present the most innovative aspects of the Nuxeo 5 project: its use of Nuxeo Runtime to develop modular applications that target both application servers and rich clients, the Nuxeo Core embeddable document management core, and the Nuxeo EP and Nuxeo RCP platforms. Hence we are looking for partners that would like to work with us on all kind of levels:

Nuxeo Runtime: either developers of other kinds of enterprise software (ERP, CRM, Enterprise Wikis…) that would want to benefit from the modularity and extensibility that it provides, or people who would want to work with us on targeting other deployment platforms than JBoss AS 4 and Eclipse (we’re specially looking for volunteers for helping with porting Nuxeo Runtime to JBoss 5, JOnAS 5, Geronimo, Glassfish, for instance).
Nuxeo Core: developers that who would like to extend to core with new kinds of document storages than the JCR, for instance a RDBMS (via Hibernate), an OODBMS (like db4o) or an XML database, add application-level replication / synchronization, etc.
Business components developers that would extend the platform with more specialized components.
Vertical application developers that would base their software on the Nuxeo platform (we already have a bunch of companies we are working with on this matter).
Other kinds of applications developers (ex: CRM, ERP, etc.) that would want either to embed Nuxeo as a document management core in their system (this makes completely sense for a system like a CRM that has to manage document besides more structured data) or just connect Nuxeo to their software.

For those who prefer slides, here they are:

Or as a PDF file, if you prefer.

JavaOne 2007: our talk about Nuxeo has been accepted

I’m very happy (some would say "ecstatic" ;) ) to report that our talk proposal for the JavaOne conference has been accepted by the program committee.

It will be called “Building an embeddable Enterprise Content Management core” and will be an in-depth overview of the Nuxeo 5 architecture, as proposed in our abstract:

This session describes the architecture and implementation of an embeddable, extensible Enterprise Content Management core for Java EE and simpler platforms.

The presentation starts by describing the general architectural concepts that are used as building blocks:

a schema and document model, reusing XMLSchemas and making good use of XML namespaces, where documents types are build using a number facets,

a repository model, using hierarchy and versioning, with JCR (JSR-170) being one of the possible backends,

a query model, based on JPQL (JSR-220) and reusing the path-based concepts from JCR,

a fine-grained security model, compatible with WebDAV concepts and designed to provide flexible security policies,

an event model using synchronous and asynchronous events, allowing bridging through JMS (or other systems) to other event-enabled frameworks,

a directory model, representing access to external data sources using the same concepts as for documents but taking advantage of the specificities of the data backends,

Suitable abstraction layers are put in place to provide the required level of flexibility. One of the main architectural tasks is to find commonalities in all the systems used (or whose use is planned in the future) to have a minimal number of concepts learned and used by the user of the framework. The result is a set of concepts that are fundamental to Enterprise Document Management and are usable through direct Java APIs, Java EE APIs or SOA. The presentation will show, for each of the main components, which challenges have been met and overcome when building a framework where all components are designed to be improved and replaced by different implementations in the future without sacrificing the backward compatibility with existing ones.

The described implementation, Nuxeo Core, can be embedded in a basic Java framework based on OSGi (like Eclipse), or in one based on Java EE, according to the needs of the application using it. This means that the core has to function without relying on Java EE services but also has to take advantage of them when they are available (providing clustering, messaging, caching, remoting, and advanced deployment).

The session includes a demo. Attendees should have intermediate knowledge of Java technology concepts and design patterns, and an understanding of the Content Management problem space.

Announcing Nuxeo Weekly News

I have just published the second issue of Nuxeo Weekly News, the newsletter we have started to publish every monday to keep the Nuxeo community informed of what’s going on with the project, and to provide some insight about where we are heading.

For those who missed it, the first issue is still available.

I will appreciate any feedback (positive or negative) about it.

Slides de la pr�sentation "Nuxeo Runtime" de Solution Linux 2007 en ligne

Je viens de mettre en ligne les slides de la pr�sentation de Bogdan sur Nuxeo Runtime.

JBoss World Berlin 2006 slides on SlideShare

I have recently published the slides for Nuxeo’s presentations at JBoss World Berlin on Slideshare,

First one, the business one, was called “Nuxeo - An Open Source ECM Vendor”, and is available here or just below:

The second one, the technical one, was called “Nuxeo EP 5 - A Seam Case Study”, it is also available just below:

Both presentation are also available more traditionnally as PDF here (technical one) and here (both of them)

Stangely, the technical presentation go 8 times as more hits that the business one ;)

Seam 1.1 almost there + insightful interview on InfoQ

As everyone should know now, Seam is an important part of our Nuxeo 5 ECM stack.

We are currently using Seam 1.0.1, but it is nice to learn that Seam 1.1 is coming along, and it’s going to be very good.

There is a very nice (like always, on InfoQ) interview of Gavin King, Seam’s creator, that explains in details where Seam is headed (rest assured that Nuxeo 5.1 will include Seam 1.1, but let’s focus on the Nuxeo 5.0 release now ;) ).

Java, OSS and innovation

“Cristiano”, from Faqs.it, has written a comment about our switch from Python to Java in his blog.

Here is my comment about his comment.

Hi Cristiano,

Thanks for your comments about our Java switch. I fully agree with you that a lot of innovations come from the OSS ecosystem, but there are some wrong facts in your remarks that I have to correct, including the following:

Python, for instance, did actually copy Java’s syntax (and concept) for annotation (called decorators in Python-speak), not the other way around.

Generics are irrelevant in dynamics languages, hence dynamic languages can’t have “out-innovated” Java on that matter.

The sentence “Python doesn’t fit in the enterprise-class web apps market” is in part irrelevant for us, because we are not only in the web apps market, but also in the rich client market (with Eclipse RCP).

Your opposition (in the last sentence) of “Java vs. OSS” is completely disconnected from the reality: Java is GPL now (or will be RSN), Java OSS communities (JBoss, Spring, Apache, Eclipse, Nuxeo…) are among the most active (if not the most active) OSS communities now. And some of these communities have a lot of money at their disposal, because these are projects for building enterprise-class OSS software (or middleware), backed by serious companies like Sun, IBM, Red Hat, or Nuxeo.

IMHO, OSS is now driving, in many ways, the development of Java, and this means that there is no need to oppose Java if you are (like I am) an OSS believer.

Seam 1.1 beta1 released

Gavin King has released last week the first beta of JBoss Seam 1.1, but hasn’t made any spectacular announcement for it, besides a post in the JBoss Seam forum.

According to his release notes, the major new features of Seam 1.1 are:

The Seam Application Framework for data-oriented applications
Asynchronous methods and events
Integration of Ajax4JSF for partial page refresh
New concurrency model for Ajax-based applications
Efficient clustering of Seam-managed extended persistence contexts and JavaBean components
Support for atomic conversations
Enhanced configuration via components.xml
Exception handling via annotations or exceptions.xml
Page parameters for RESTful applications
Page fragment caching via <s:cache/>
“Decoration” of invalid input via <s:decorate/>
Themes
Support for the Sun JSF 1.2 reference implementation

Michael Yuan, author of the upcoming Prentice Hall Seam Book, also has some comments on the new features.

As developers of the Nuxeo 5 open source ECM platform, which relies heavily on Seam for its web presentation layer, we are both excited by this new release, and curious about other projects (open source or not) that are using the Seam framework.

Maven workshop with Vincent Massol

Vincent Massol, of Maven and Cargo fame, came to visit the Nuxeo 5 team yesterday to give us some advice on how to best use Maven 2 to build and deploy Nuxeo 5 and ensure the best possible software quality for the product.

So, expect a few changes (= improvements) to the project’s SVN structure, the Nuxeo 5 Maven site and of of course the build system if you are already a developer (if you’re not, I strongly encourage you to consider becoming one.)

And, BTW, we have identified a few features we could add someday to Maven (as a plugin) or Cargo, so expect some contributions from us in the future (expect, but don't count on it before the Nuxeo 5.0 release next month.)

Another review of Mike Milinkovich's keynote

Well, it seems Mike doesn’t have enough time to prepare a new keynote each time he has a speaking engagement ;)

This review of his keynote at CSS2006 seems suspiciously similar to the one I saw in Esslingen am Neckar two weeks ago.

Anyway, just kidding: this was an awesome keynote and if you missed it, or my summary of it, or the CSS 2006 version, you still have my and Matt Raible’s blogs entries to read it (I wonder if the slides are available somewhere, though).

"Eclipse Now You Can" slides are now online

The slides for the presentations given at the "Eclipse Now You Can" (including mine of course), are now online.

The conference was a smashing success, btw, with 100 attendees for 100 seats ;)

I'm now an Eclipse pundit ;)

It's official now :) !

1. I have given a talk at an Eclipse conference.

2. My blog (like Eric's and Bogdan's is now aggregated on Planet Eclipse.

Slides for my Nuxeo RCP and Apogee talk at the Eclipse Summit Europe

I’m just coming back from the Eclipse Summit Europe 2006 which was a great conference (more reports on this blog later).

I had the chance to do a short (20 minutes) but exciting ( ;) ) presentation of two projects we are involved in: Apogee and Nuxeo RCP.

My slides are now online on nuxeo.org, or on the conference website.

Eclipse Summit report, day 1, Mike Milinkovich's keynote

Mike Milinkovich started the conference by highlighting the four ingredients of a great platform:

Great technology
Broad adoption
“Architecture of participation”
Hijacked by the community

Great technology

Eclipse is a platform that you can extend through plugins. It is already well-known as a Java IDE, but there are plugins for many more languages (C/C++, Java, Python…). If you remove the language plugins, you are left with RCP, which is a great platform to build rich applications.

Broad adoption

The Eclipse Foundation now has 150 members. Eclipse has about 60% market share in the Java IDE market. Eclipse 3.2 was downloaded 1 million times in the 47 days after its release. The eclipse.org website has 36000 unique visitors / day.

Architecture of participation

The aim of an architecture of participation is to create a “free market for ideas”, by lowering the barrier to entry for contributions. It has been enabled by the plugin system of Eclipse. “You need a cathedral to enable the bazaar!”: the core must be developped in a very rigourous manner, and then there must be a lot a freedom for people developing add-ons.

This is similar to the way Apache httpd is extended by different modules (mod_*) or to Mozilla Firefox extensions, etc. OpenOffice.org is also moving in this direction, thanks to the efforts of people like Laurent Godard.

“Hijacked by the community”

“Hijacked” refers to a book called “Brand Highjack” by Alex Wipperfurth (cool, a new book for me to read ;) ), which advocates “allowing customers to shape brand meaning and drive a brand’s evolution”. Mike, like me, is a reader of the “creating passionate users” blog by Cathy Sierra. He (or she?) says: “Fire the marketers. We are all marketers now”. Marketing is not done by other persons, but by ourselves as technologists.

Conclusion

In conclusion, Mike stressed that Eclipse RCP is the part of Eclipse with the greatest potential and highlighted a few success stories.

Overall, this was a great and inspiring keynote. The Eclipse architecture and process are both a tremendous inspiration for us with our Nuxeo 5 project, where we also have developped a plugin archtecture (using the same underlying technology as Eclipse, OSGi), we aim for clean API for external developpers, we want to help build a community of third-party contributors and extenders though, and of course we are using Eclipse as a Java IDE and as the foundation for our Nuxeo RCP project.

What a month! (Quick reflections two weeks after our Java switch)

We announced our switch to Java two weeks ago. There was of course a lot of preparation before the announcement (besides just coding). That included: creating the new Nuxeo.org website, writing a FAQ, preparing slides, writing announcements for various media (InfoQ, TSS,…), and anticipating some discontent in the Zope community.

Well, two week after going public with the announcement, I’m glad to say that we are completely pleased with the way things went.

We already have released one of the key components of the platform, Nuxeo Runtime and are preparing to release Nuxeo Core this week. Overall, work on the project is going on at a steady pace and we are on track to meet the next milestones of our roadmap.

Our announcement got noticed both by the main Java sites, and countless blogs (including some in languages that we don’t understand without Google Translator).

There has been a little discontent, as expected, in the Zope community, but we mostly got some nice messages of people saying they understood our choice. The most heated discussions took place after Jean-Marc’s post (and its followups) supporting our change.

And, most importantly, we got many subscriptions to the mailing list, which shows there is a real interest in the developer community.

On the business side, we’ve had many calls from system integrators.

I’m especially glad to notice that in two weeks, we got contacts from several new systems integrators, telling us that, now we are using Java, they will be very happy to work with us on new projects. Consequence: we now have a commercial contact with 8 of the 10 leaders of ECM integration in France (some of them the french subsidies of international groups), as well as interesting partnership projects with a big name (I mean BIIIIG) software vendor (more on this another day).

Meet me at Eclipse Summit in Esslingen (or Eclipse Now You Can conference in Paris)

I will be in Esslingen next week for the eclipse Summit.

I’m going to talk about Nuxeo RCP, the rich client side of our Nuxeo ECM project, and about the Apog�e project, which is now an official Eclipse Foundation technology project.

Then I will be at the Eclipse Now You can one day conference in Paris. Similar program for us, except I won’t be delivering the talk myself (you have to share the fun of giving talks with your colleagues, right Laurent ;) ).

I’m looking forward to talk to people interested in our project, so we can discuss how to best collaborate together.

Watch this space for a report on both conferences, and for the slides that are not done yet.

CPS4/Z3ECM sprint, day 3, short report

Yesterday was the third day of the Z3ECM / CPS4 sprint.

Florent and Dario are now able to create complex Zope3 schemas from the JackRabbit schemas. There is now a nuxeo.capsule package that contains just base classes and a nuxeo.jcr package that contains the parser. The next steps are to create new node types in the JCR, export them at startup, and have Zope to parse them as interfaces and schemas. Then we have to find out how to exactly use them.

Jean-Marc took the upcoming Zope 2.10 branch (w/ Philipp's and Jim's branches) and get all the ZCML files parsed and the utilities registered, etc. Then he started to look at Jim's refactoring of local utilities to use the same API. He is now half-way in getting something that works. The next step is to register these utilities in Zope 2.

Michael got the Zope 3 publisher to work in Zope 2 for ZServer.You can now use all the 4 combinations of Zope 2 publisher vs. Zope 3 publisher, and ZServer vs. Twisted.

Tarek has worked on a CPSResourceLibrary, similar to zc.resourcelibrary. It's now finished. Joachim has used it on some portlets. Tomorow Tarek is going to look into the use cases of the JS library packaged on monday in CPS 3.4.

CPS4/Z3ECM sprint, day 2, minimal report

Yesterday was the second day of the Z3ECM / CPS4 sprint.

Michael and Lennart have got Zope 2 working on a Twisted server. They are using the Zope 3 publisher now in Zope 2. No benchmarking has been done yet. The code lives in Sidnei's publication-refactor branch of Zope2 (Sidnei did most of the work).

Tarek, Joachim and Jean-Marc have worked on CPSSkins integration. There were many branches. They finally landed on a Philikon branch where Jean-Marc did all the hard work. Tarek is now working on a "resource library" for Zope 2. Joachim is trying to use the JS library package that was created yesterday manually.

Florent and Dario have written an importer for JCR schemas expressed in CND notation. They have a parser for that and are able to build a Zope 3 schema from it. They are now stuck on the fact that the JCR can have children with the same name.

CPS4/Z3ECM sprint, day 1, short report

The sprint has started yesterday with notable guests Jean-Marc and Dario from Chalmers, Joachim from AixtraWare, and Michael from OpenApp, and a bunch of Nuxeo guys.

The goal is still to provide Zope3 ECM components for CPS4

Yesterday morning was spent discussing the AJAX and JavaScript MVC features of CPSSkins v3 (more info in Jean-Marc's numerous messages in the mailing list, or on the z3lab website).

Then we had a discussion about the JCR content model and the JCR schemas for documents (JackRabbit's CND).

In the afternoon, work has proceeded in pairs or small groups.

Florent and Dario have investigated existing schemas sytems and are trying to find a common subset. Now, they will code and write an importer for the JCR schemas.

Lennart and Michael are looking on how to plug the Zope3, Twisted-based, publisher into Zope2.

Jean-Marc, Tarek and Joachim are working on AJAX and CPSSkins. They have created small package of all the ressources used by cpsskins so that they can be reused in CPS. The goal now is to instanciate de Zope 3 CPSSkins utilities in Zope 2, look for breakages, and fix them.

Bogdan is working on Apogee integration through ICE.

CPS4 project officially started!

Two signs that the CPS4 project has officially started:

Florent has committed a roadmap in the SVN. (This roadmap will obviously be the basis for next week sprint at Nuxeo's office in Paris).
The CPS4 mailing list is now open for the community (and last week's private discussion archives are available too).

Now, you may ask, "what is CPS4?"

In a couple of sentences, that will be expanded in upcoming blog postings: CPS4 is the evolution of CPS3 towards more openness and more scalability. We keep all the ECM functions we like in CPS framework (the repository, the documents schemas, the directories, events, skins, portlets, relations...) , and we leverage both the work done on the Z3ECM project, and the offering of the Apache project (Lucene, Jackrabbit) and a few other established infrastructure Java projects. Last thing: we plan to use the ICE high-performance communication engine for communication between the different components.

FAQ: "Is the CPS 3.4 branch still supported?" R: of course, we also plan to do a CPS 3.4.1 release very soon.

Tag your Trac too!

As you already know, I have started two weeks ago tagging (and asking others to tag) their CPS sites on del.icio.us with the tag "cps-site". I think we have spotted about 80 public CPS sites so far, but I'm sure many are still missing.

BTW: how do you know a website is a CPS site? There are several clues: 1. Look at the icon, if present. 2. Look at the urls (if it contains "section" it's probably a CPS site). 3. Look at the HTTP "Server" header.

Now I have a similar idea: there are many Trac site out there, and Trac is one of the "Python killer-apps". So let's tag also Trac sites with the trac-site tag and see what happens.

Packaging CPS

Packaging CPS is important for ease of installation. Unfortunately, it is also a great deal of effort, but an effort that can be distributed between the original software developers and third-party packagers.

The situation so far for CPS is that we have:

the "big tarball", that installs itself on a fresh Zope 2.9 instance, made by the CPS dev. team.
the Windows installer, which installs Python + Zope + CPS + additional librairies + additional software (converters), made by Ruslan.
the Debian/Ubuntu packages, made by the Debian Zope Packaging Team, and specially Fabio Tranchitella
Gerardo Puerta has made an ebuild for Gentoo.

There are some areas were would benefit from some external help, though:

We are still working on the Mac OS X installer, for which some preliminary code has been written, but I have been told that the current approach is a dead-end and we need to start afresh with a new approach.
There are still not satisfactory RPM packages for common distributions like Fedora, Mandriva or OpenSuse.

Packaging Zope and Zope applications under Linux is challenging, because you have to accomodate both people who just want "one click install" (using apt-get / yum / urpmi), but also provide the basis for rock-solid, possibly multi-instances, Zope server management (including easy instance creation / deletion, log rotation, service initialisations, etc.) without compromising security. The Debian Zope team seems to have done a lot of work to streamline this process for Zope.

Regarding CPS, any help in improving the existing packages, or in making new packages kinds available, would be really appreciated. If you feel in a packaging mood, join the cps-devel mailing list and let's start working together.

Nuxeo recrute

Je viens de poster deux annonces sur Lolix: une pour un (ou plusieurs) d�veloppeurs Zope/CPS (profil: IUT ou ing�nieur, un go�t prononc� pour la d�veloppement d'applications open-source) et une pour un sysadmin.

A CPS project awarded by french magazine "Le Monde Informatique"

Our friend at CEA (French Atomic Energy Commission) have been awarded "best project of the year" in the "public administration" category of the competition organised by the french magazine "Le Monde Informatique" (an IDG publication). They have been using CPS for 3 years and now have 129 instances in production.

According to the article (p. 19), the use of CPS has allowed for 1.9 to 3.8 millions Euros savings over 3 years.

(Note: last year, CPS won 2 awards in the same competition, one for CNCC.fr and a second one for Ardeche.fr! Check for yourself in last year's article).

Tag your CPS sites on del.icio.us

Yesterday, following a suggestion of Tarek, we have started tagging public (internet) websites developped with CPS on del.icio.us with the tag cps-site.

After one day, we already have more than 60 sites. Not bad, for a system that we know is more often used for intranets (ECM, if you prefer) than for internet websites.

Please join the "CPS sites hunt" and add the tag to your sites.

CPS 3.4 has been slashdotted :)

The news of the CPS 3.4 release has been slasdotted today.

Both the announcement on nuxeo.com (which runs CPS 3.3.8) and the brand new cps-project.org (which has been upgraded to CPS 3.4.0, and which sports a new home page and updated content), where linked from the Slashdot news.

Despite the increase in visits number, the server (which hosts both sites, as well as a few others) hasn't had the slightest hickup, thanks to the performances work we've done during the CPS 3.3/3.4 development cycle.

CPS 3.4.0: screencasts and Windows installer available

As you probably know already, CPS 3.4.0 was released this monday and it really rocks (at least, that's the feedback we've had from our users so far)!

We've already posted an announcement on nuxeo.com (here in english, and here in french), as well as on zope.org (here) and freshmeat ( here).

Now, the release and the early announcement are just the beginning, because we really want people to try out this new version.

We have created our first screencasts (in Flash, using Macromedia Captivate - there is nothing wrong with pyvnc2swf, but it only addresses capture, not editing).

And we have a Windows installer, that bundles about everything (Python, Zope, CPS, wvware, ppthtml, xlhtml, xsltproc...) that's needed (even non-mandatory tools) to run CPS on Windows, installs CPS in 4 clicks, and provide a GUI controller for the CPS instance.

There is a lot more work to do (update cps-project.org, update the white papers about CPS, more screencasts, create packages for Linux and MacOS, etc.).

DADVSI: lette ouverte des industriels du libre au Premier Ministre

Nuxeo est cosignataire, avec Sun Microsystems, ADULLACT, Mozilla Europe, IDEALX, MySQL et Mandriva, de la lettre suivante adress�e la semaine derni�re au Premier Ministre:

Monsieur le Premier Ministre,

Les �v�nements qui ont accompagn� � la fin du mois de d�cembre 2005 le vote de la loi sur les droits d'auteur (DADVSI) ont d�montr� combien ce sujet �tait � la fois sensible etcomplexe. C'est dans un souci de clarification que les industriels de logiciel libre signataires de cette lettre s'adressent � vous, Monsieur le Premier Ministre, en esp�rant que vous donnerez une �coute favorable aux diff�rentes points que nous soulevons.

L'amalgame qui est souvent fait entre le logiciel libre et les moyens de partages de contenus ill�gaux nous semble tout � fait abusif. Notre d�fense nationale (Gendarmerie, arm�e, police), une grande partie des nouveaux services administratifs en ligne (t�l�d�claration des imp�ts) ainsi que la majorit� des grands industriels comme France T�l�com, Thales, IBM ou Sun utilisent quotidiennement pour leurs besoins propres (transactions en ligne, t�l�chargement de rustines logicielles, ...) ou vendent � leurs clients des solutions bas�es sur logiciels libres (dont le code source est publiquement accessible et modifiable). Non seulement ces applications se situent dans un usage strictement l�gal mais elles utilisent les qualit�s de robustesse et de s�curit� reconnues aux solutions dont le code est ouvert � tous. L'exclusion du logiciel libre, aujourd'hui envisag�e pour cause d'usages illicites, viendrait en totale contradiction avec le � patriotisme technologique � que vous d�fendez, Monsieur le Premier Ministre, dans votre discours du 27 juillet 2005 en privantnos industries nationales et nos administrations du choix d'alternatives technologiques ouvertes et fiables.

Car l'Europe a d�j� compris que les opportunit�s repr�sent�es par le logiciel libre de reconqu�te de son ind�pendance technologique et de sa capacit� � innover devaient �tre saisies le plus rapidement possible. La France, � cet �gard, fait figure de pionnier et a r�ussi � construire une offre industrielle et une base d'utilisateurs qui maximisent nos chances d'�tre un acteur majeur des march�s �mergents. Nous sommes cependant persuad�s que tout article de loi qui permettrait, m�me dans un nombre limit� de cas, de criminaliser la publication du code source des logiciels (qui est le principe fondamental de notre industrie) condamnerait cette dynamique encore fragile et remettrait en cause les avanc�s que notre pays a faites dans ce domaine tout en l'excluant pour longtemps des ouvertures techniques, �conomiques ou culturelles qui sont port�es aujourd'hui par le logiciel libre.

C'est donc en termes d'opportunit�s que nous vous proposons de penser ce d�bat. Internet permet par exemple � tout individu de devenir le producteur de son propre contenu (blog, site personnel, partage de photographies) qu'il doit pourvoir distribuer avec une libert� qui doit rester aussi intacte que celle de sa vie de citoyen. Dans cette optique, il nous semble difficile de globaliser la probl�matique de la protection des donn�es sous une seule et m�me d�finition qui couvrirait � la fois musique, vid�o, jeux �lectroniques, logiciels et respect de la vie priv�e de chaque citoyen ou confidentialit� des informations des entreprises. L'�ventail des technologies susceptibles d'apporter des r�ponses satisfaisantes pour les utilisateurs ou les ayant droits des contenus restent encore � trouver. Nous sommes cependant convaincus que l'innovation dans ce domaine ne pourra s'exercer pleinement que dans la mesure o� aucune communaut�, aucun acteur impliqu� dans Internet, dans l'�dition du logiciel (et en premier lieu le d�veloppement du logiciel libre) et dans les standards ouverts ne sera exclu du d�bat actuel et des solutions � concevoir et � d�velopper pour demain.

C'est dans cette perspective que nous nous adressons � vous, Monsieur le Premier Ministre et que nous vous proposons de r�fl�chir ensemble � une coop�ration ouverte et constructive.

En vous remerciant par avance de votre attention et de votre r�ponse � venir, nous vous prions d'agr�er, Monsieur le Ministre, l’assurance de notre haute consid�ration.

Funkload-related talk at PyCon 2006

Tres Seavers (of CMF fame), has put online the slides of his talk at PyCon "New Tools for Testing Web Applications with Python", which covers both Selenium and our own Funkload (functional and load tester for web applications).
Thanks Tres!

JavaScript to become more pythonic

Read on Brendan Eich blog:

Given the years of development in Python and similarities to ECMAScript in application domains and programmer communities, we would rather follow than lead. By standing on Python’s shoulders we reuse developer knowledge as well as design and implementation experience. The trick then becomes not borrowing too much from Python, just enough to gain the essential benefits: structured value-generating continuations and a general iteration protocol.

And:

The wiki in which I typed that brief "let's be Pythonic" argument quoted above is a docuwiki instance set up for ECMA TG1 by Graydon Hoare, who (I'm thrilled to report) has joined us at Mozilla recently. We hope to make this wiki world-readable at some point not too far off. In the mean time, I will blog with more details about the emerging ES4 language design, and about what features from it will show up when in JS1.7 and higher numbered versions to be shipped in Firefox 2 and 3.

More info here.

CPS chez Areva: alternative � Documentum pour la GED

Une petite recherche sur Google sur le th�me "areva nuxeo", fait ressortir des slides de Christophe Le Cannellier, de la DSI du groupe Areva, sur le th�me "retour d'exp�riences sur le logiciel libre", correspondant � une pr�sentation donn�e il y a 6 mois.

On peut y lire notamment (slide 7): "L'identification d'axes de d�veloppement prioritaires : - GED : alternative � Documentum avec CPS de Nuxeo.".

L'Histoire (avec un grand "H") �tait deja en marche... :)

Bugday going on for CPS 3.4.0

The bugday is going ont now. There are 25 people registered on the #cps IRC channel (on freenode.net), 50% from Nuxeo and 50% from "the community" which is great. I think it's our record attendence so far. The timeline should hopefully show many bug closes by the end of the day.

About the Eclipse Dynamic Languages Toolkit proposal

Xored software has submitted a while ago an Eclipse project proposal for a "Dynamic Languages Toolkit".
The aim of the project is to provide a framework and core components to support "editing, code navigation, debugging, and refactoring of code in dynamic languages", with Python, PHP and Perl as primary targets.
To proceed, this project needs to gather support from other interested parties. If, like me, you believe this project could provide a big boost to Python adoption in the software industry, you should probably get in touch with the guys from xored (info@xored.com) (sorry, I can't find information on the "proper" way to move this proposal forward).

Popularity of Python packages in Debian: High !

Ara is an advanced search engine for Debian packages developped in the EDOS project (of which we are also taking part).

Out of curiosity, I checked today how many Debian packages were implemented in Python (this is one of the metadata that are searchable using Ara).

The result is: many! Python is a close second behind C, and way ahead other languages (including some who are supposed to eat Python for breakfast!).

C: 861
Python: 784
C++: 234
PHP: 192
Ruby: 127
OCaml: 124
Java: 59

(Warning1: these results depend on metadata that may not have been set up correctly for every package. Warning2: these number will obviously change over the time.)

Slides Solutions Linux: "Connectivit� CPS et Eclipse"

Bogdan pr�sentait hier lors du salon Solution Linux notre travail autour du client riche pour CPS: le projet Apog�e, bas� sur Eclipse RCP, que nous venons notamment de soumettre � la Eclipse Foundation.
Ses transparents (PDF, OpenDocument) sont maintenant disponibles.

Au fait: Nuxeo recrute. Si vous �tes francophone, ressortissant de l'Union Europ�enne, et que vous souhaitez travailler sur le d�veloppement de produits open source comme Zope/CPS et de projets bas�s sur ces produits, consultez les annonces sur cette page du site Nuxeo.

Zope at the Royal Bank of Scotland

ZDNet UK has an article about a massive Zope deployment at the Royal Bank of Scottland (for an Intranet, it seems).

Unfortunately, the article gives absolutely no functional nor technical details. So it's hard to know of if this project is more impressive that some of the projects we did recently.

Congratulations anyway to the people who worked on the project.

CPS 3.4.0beta1 released

I've just posted several announcements for the CPS 3.4.0 beta1 release. It was a bit tiring since many things have changed since CPS 3.3.8 (we did an "alpha" in late december, but it was not packaged, just an annoucement in the dev mailing list).

There is still a lot of work to finish before we finish (at least a beta2) but I'm confident we are on the right track.

Updated megaframeworks concept map

Here is an updated concept map ( PDF, PNG) of five Python megaframeworks (Turbogears, CPS, Django, Subway and Pylons) and their relationships to other Python frameworks and libraries.

Thanks for the comments on the previous version.

"Programmation Python": site launched and book soon to be available

Tarek has put some finishing touches this week-end on the programmation-python.org website, which is going to support the book he has recently finished for Editions Eyrolles, which is going to be available in bookshops on jan 19th.

Of course, the website runs CPS ;)

Python megaframeworks concept map

Here is a map ( png, pdf) that I've just drawn to try to clarify the dependencies between the so-called frameworks and "megaframeworks" and other Python packages.

I have tried to cover, so far:

Zope (w/ CPS as an example of a framework built on top of Zope)
TurboGears
Django
Subway
Pylons

Feel free to comment. I'm probably wrong in many places. (Even the CPS part may be wrong ;) ).

It's official: I'm James Bond!

You scored as James Bond, Agent 007. James Bond is MI6's best agent, a suave, sophisticated super spy with charm, cunning, and a license's to kill. He doesn't care about rules or regulations and somewhat amoral. He does care about saving humanity though, as well as the beautiful women who fill his world. Bond has expensive tastes, a wide knowledge of many subjects, and his usually armed with a clever gadget and an appropriate one-liner.

Beginners Python tutorial spotted on IBM DeveloperWorks

Discover Python is a series of articles written by Robert Brunner, Research Scientist at the National Center for Supercomputing Applications, and published by IBM DeveloperWorks.

According to the intro:

The flexible nature of the Python programming language supports multiple programming philosophies, including procedural, object-oriented, and functional. But most importantly, programming in Python is fun. The language supports rather than hinders the development process.

The articles are very basic, and clearly aimed at scientists with little knowledge in programming.

For a similar approach, see also the Software Carpenty lecture notes by Greg Wilson.

CPS lays a (big) egg

I'm experimenting with eggification of CPS, trying to have support in place for the upcoming CPS 3.4.0 release. I already have something basic working, here is how to test it:

Create a fresh Zope 2.8.4 instance (with Python 2.4).
Download the Basket product from http://www.plope.com/software/Basket/Basket (I have tested with version 0.2)
Download the CPS egg from http://www.cps-project.org/static/eggs/
Create a lib/python directory in your instance, and put the egg there
Start Zope and play with CPS

Remarks:

If it doesn't work, you may checkout CPS3 from SVN from http://svn.nuxeo.org/pub/CPS3/trunk and, type 'make' then 'make egg' and hack the setup.py until your egg is working (well that's how I did it anyway). Then send me the patch or commit your changes if you have SVN access.
The big egg will be broken into smaller eggs. I fact, that is the main reasons to have eggs in the first place, because currently the installation procedure is not simpler that with the normal tarball.
I hope the Basket product will be integrated soon into Zope, though I understand it's already too late for Zope 2.9.

BTW: kudos to chrism for the Basket product!

Who's the real leader in open source ECM?

Don't believe the hype, just ask Google:

"cps ECM": 98800 results
"zope ECM": 91300 results
"nuxeo ECM": 55700 results
"plone ECM": 33500 results
"alfresco ECM": 25800 results

Added later: for more serious arguments, see Eric's blog entry on the same subject.

Next CPS Bugday: next Wednesday (dec 14)

Next CPS bugday will happen on IRC channel #cps next wednesday (dec 14). There are still 77 issues left before we release CPS 3.4.0, but we are confident that the number will drop to a less spectacular level with the help of the CPS developers community at large, and the dedication of the CPS core team.

For more info on CPS development:

The cps-devel mailing list.
The Trac (with SVN browsing, timelines, roadmap and outstanding issues).
The #cps IRC channel on freenode.net.

FunkLoad 1.4.0 released

Here is the announcement on Freshmeat:

New command-line options have been added for looping on specific pages inside a given script, for ignoring image/CSS link errors, for filtering tests based on a regular expression, for stopping the tests on the first failure, and more. Reporting has been improved. The API has been cleaned up a bit. ez_setup has been upgraded to fix broken SourceForge download.

BTW, other Zope superstars with blogs on z3lab include Jim Fulton (aka "The Zope Pope") and Jean-Marc Orliaguet (no nickname yet, you now, he's the guy behind CPSSkins).

Zope 3.2 and 2.9 beta coming today

Great news: the first beta of Zope 3.2 should be released today, according to Jim Fulton, "The Zope Pope", and Zope 2.9 beta1 (which will include Zope 3.2beta1) later this week, according to Andreas Jung, release manager for Zope 2.

D�tail amusant: il parait que Microsoft avait aussi un s�minaire baptis� "Perspectives 2006" le m�me jour. Enfin, on ne peut pas dire qu'ils nous ont fait de l'ombre, la salle que nous avions r�serv�e �tait pleine et tout le monde �tait content.

Next CPS Bugday: next Wednesday (Nov 23) - getting ready for CPS 3.4

Florent just tells me we'll have a CPS bugday next Wednesday (Nov 23).

Please join us whenever you can on that day on IRC in #cps (on irc.freenode.net).

The goal is to diminish the number of bugs targetted for 3.4.0 (see http://svn.nuxeo.org/trac/pub/report/13)

Slides: Introducing FunkLoad

Here is a set of slides (pdf - 200 kb) introducing our web testing tool, FunkLoad.

FunkLoad is a functional and load/stress testing tools writtent in pure Python.

And remember: "if it is not tested, it's broken".

CPS 3.3.7 to be released this week

We'll be doing a release of CPS 3.3.7 this week, after we fix a few more bugs, the most important one being:

http://svn.nuxeo.org/trac/pub/ticket/1029

It won't include Jean-Marc Orliaguet's work on "boxless setup" (rendering based only on portlets) which is still a bit instable and should wait for the CMFSetup Geddon.

So, CPS developers, please don't try new funky stuff this week (or try it in branches) and keep fixing bugs if you can.

This release already looks like one of the best and strongest since the 3.3 branch has been started. Let's keep up the good work until friday.

Second CPS bug day tomorrow (2005/10/27)

OK, this is a bit late, but here is the announcement:

Please everybody join us in #cps on IRC on irc.freenode.net tomorrow (27 october 2005).

The goal of this bugday is to fix as many bug as possible for the upcoming 3.4 release.

This stable release will include, among all bugfixes several enhancements:

    * Zope 2.8.1 and CMF 1.5.3 required
          o Zope 2.8 gives much better conflict behaviour
    * Full CPSSkins integration
          o No more boxes
    * Optimize document indexing
          o Indexing done once at the end of the transaction
          o Correct for multilingual documents
    * Packaging
          o CMFSetup
          o Business templates
    * Notification management
          o i18n of notifications
    * User management
          o Default to CPSUserFolder
          o LDAP profiles
          o PAS with directories
    * Functional modules
          o CPSWiki
          o CPSBlog
          o Comments

"Some Zope 3 Quick Starts and Resources"

Jeff Shell has just posted a reminder for several introductory documents and tutorials about Zope 3.

Nice thing about it is that he even mentions z3lab.org, a project dear to us at Nuxeo:

This site has blogs, documentation, proposals, movies, prototypes, and more, for building a high class content management platform on top of the Zope 3 framework. There is a lot of information and ideas floating around here, and the animations are very impressive.

CPS Bug Day today !

As anounced in the mailing lists, but not on this blog, today is the first "CPS Bug Day".

We intend to triage and fix a maximum number of bugs and issues in the current development branch (CPS 3.3.x), to prepare the next CPS 3.3.6 release (hopefully the last one before CPS 3.4).

So if you are interested in helping the CPS team, please join the #cps channel on IRC (on the Freenode network).

coverage.py, profile and hotshot support in Zope's testrunner

I have added support for coverage analysis using coverage.py from Gareth Rees and Ned Batchelder, as well as support for profiling using either the profile or hotshot modules from the Python standard library, to Zope 2's test runner test.py.

See the attached file.

S. Fermigier first law of project management

Just thought it out while discussing with Ruslan:

Proof: just apply twice the 80/20 principle (also known as Pareto's principle). Details are left as an exercise to the reader.

Compaison Rails vs. Django

Rails est un framework web MVC pour le langage Ruby qui connait une certaine popularit� en ce moment.

Django est son plus proche �quivalent dans le monde Python.

Les deux projets sont issus de projets sp�cifiques (Basecamp pour Rails, Lawrence Journal World pour Django) et ont �t� g�n�ris�s ensuite.

Sam Newman vient d'�crire A comparison of Django with Rails, et conclut sa comparaison assez �quilibr�e des deux frameworks par:

I said at the start that the two frameworks were developed as a result of two very different applications - and most of the differences between the two are a result of this. If you are developing a simple (in a domain model sense) application where you want to use Ajax to deliver a great UI, Rails is probably for you. If however you want to develop an entire site with different types of applications within it - then Django’s plugable applications and general approach might be what you’re after. Equally, the better user and administration side of Django favours portal style applications – this is something you’ll have to do yourself if you want to use Rails.

There is scope for both frameworks to learn from each other, and I still have a question around how well Rails will scale (in terms of the size of the site, not number of hits) - Django has already proved it is capable of this with LjWorld.com. Likewise it will be interesting to see if Django can or even wants to make the use of Ajax as simple as it is with Rails (although work is already progressing along these lines), or if the more powerful language features of Ruby will prove the deciding factor.

Ce qu'il manque � pr�sent, c'est une comparaison avec Zope3...

Philip Eby on Java+XML vs. Python and the sin of overengineering

Philip Eby has some comments on the Chandler development team recent decision to drop its XML-based "parcel" (parcels are components in Chandler) description format in favor of a pure-Python solution.

There are two interesting lessons in his post:

Of course, the real sin here was not so much XML per se, as overengineering in advance of requirements. If you're not developing the feature now, it's best not to make a bunch of other design decisions based on what you think the feature will need. A little thing like choosing to put data in XML form can result in a wide variety of additional costs like:

Designing the XML format

Implementing a parser

Documenting the format

Developing a bunch of stuff in the format

Evolving and fixing the parser to handle more and more complex use cases that weren't thought of previously

Productivity losses versus what it would've been with Python

Converting all the data once you decide it was a bad idea, or else paying the ongoing marketing and education costs to get third-party developers over the hump, or the cost of not getting those developers on board

And:

I've certainly worked for organizations where the reverse is true, though, including one that threw away tens of millions of dollars trying to replace a small, well-designed Python application with an expensive piece of "enterprise" crapware. Ah, the things I could've done with that budget! Well, probably I just would've given everybody raises and maybe hired a few more people. Or maybe spun off my group as a company that would sell the software to other companies. Heck, we could've used it to buy free sodas for life for everybody working in the company and got more value for the investors than what was actually done with the money!

"Official" (though still experimental) packages of CPS for Debian available

Fabio Tranchitella wrote me this morning that Debian packages for CPS were available at his experimental Debian Zope packages web site.

More information in this message I sent this afternoon to the cps-devel mailing list.

Debian-based distribution vendors form the Debian Common Core Alliance

The press release says it:

Major Linux vendors and non-profit organizations today officially launched the DCC Alliance. The Alliance plans to assemble a common, standards-based Debian core for Debian-based Linux distributions, accelerate worldwide commercial adoption of Debian, promote compatibility among the growing community of Debian derivatives, and work with Debian on features important to commercial adoption such as a predictable release cycle and Linux Standard Base (LSB) compliance.

Interestingly, Ubuntu is not part of the founding members.

Slides for my "Python best practices" talk at RMLL available

The slides for my "Python best practices" talk at the "libre software meeting" in Dijon 10 days ago are now online after some minor polishing.

Unfortunately for non-french speakers, they are in french (but with a faire dose of english quotes and technical lingo ;) ) but I hope you will enjoy them anyway.

I don't consider the talk to be finished, there are many more things I'd like to add over time. You're very welcome to send me your comments by email (sf at nuxeo dot com)

I thank Stefan Holek whose talk on "choosing good names" at EuroPython 2005 was an inspiration for this talk.

And, BTW, it's official now:

Pythonic is better than unpythonic ;)

Democracy 1 - Commission/Council/EPO/BSA/Patent Lobby 0

Great day for the European Democracy today: the software patents directive proposed by the European Commission, backed by the European Council, initiated by the European Patents Office and BSA, and supported by a horde of corporate lobbyists has been rejected.

The directive was rejected by a majority of 648 votes against 14, something unprecedented in the EU history.

For more information about the news, read:

Michel Rocard discourse just before the vote (in french and english), also available as audio (MP3)
FFII's press release about the vote

Top 10 reasons to use CPSSkins according to Jean-Marc Orliaguet

Jean-Marc's slides for his Europython 2005 talk are now online.

One great thing about his talk is that he's come up with a "Top 10 reasons to use CPSSkins" which are:

10. modify your site design without restarting the server
9. cache page fragments without setting up a Squid
8. create a design that works on all CSS2-compliant browsers
7. do tableless design without spending hours on it
6. respect Web standards without reading the W3 specs
5. create visual variation across your site
4. prevent content creators from altering the site's design
3. allow content creators to be more creative, but not too much
2. focus on form and content and not just on technique
1. don't reinvent the wheel, spend time on real development

One can read more background information about CPSSkins in Jean-Marc's last year talk (but this was before the introduction of portlets into the framework, so things have changed quite a bit this last year).

I think that CPSSkins doesn't yet have the success it deserves, probably because people don't yet get the whole advantage they can get from using it, and this is a shame because it is really a terrific product.

The Economic Majority website want your support (against software patents)

The Economic Majority (against software patents) webstite now has more than 1500 supporters which is already a fair number, but could use even more support before the software patents directive get voted by the European Parliament next week.

There are also many more testimonies than last time I checked.

Unfortunately, some MEPs, like Mr Edward McMillan-Scott (brittish, conservative, vice-president of the Parliament) don't seem to get it, and still believe that software patents will protect the small business against the big corporations (they don't seem to have read a single line of all the economic litterature that has been written on the subject, and certainly not listened to the real entrepreneurs out there).

Slides for my CPS Platform presentation at EuroPython

My slides are now online.

I tried to give a rather technical talk, by emphasising the innovative aspects of CPS (repository, proxies, workflows, shemas, documents, directories...).

It was still an introduction however, more technical details can be found in Julien's ( CPSPortlets: architecture overview, CPS3/Z3ECM: from stateful to activity-based workflow), Florent's ( Versioning and relation management in a Zope ECM), Tarek's ( CPSMailAcces: a webmail for CPS3) and Jean-Marc's (CPSSkins) talks this year, as well as Julien's talks last year.

Sprint wrapup

Here is a non-exhaustive list of what people have been doing during the sprint, as was reported during the sprint wrapup:

Jean-Marc Orliaguet: has ported (in fact totally rewrote) CPSSkins for Zope3. The "main content area" (the place where the current document or folder is displayed) is now a portlet like all the other portlets.

Ph. von Weitershausen: we need a common vocabulary for portlets, pagelets, whatever. Otherwise it gets confusing.

Tres Seavers: has worked on the pipeline machinery. The point is to be able to define series of transformations that apply to an input. A pipeline is a list of callable objects. For example, a pipeline that converts an XML document to a DOM, then does something to the DOM like adding some elements, then converts it back to a string. The code for pipeline itself is not very interesting.

Tarek Ziad� / Godefroid Chappelle: AJAX development for Zope = AZAX. We have created a model where yuo creat .azax files that are combined with .pt files, and a preprocessor creates on the fly the JavaScript code that is included in the HTML page. Everything else is standard AJAX. The benefit for the developer is that he/she doesn't have to write complex JS code.

Florent Guillaume: after I started coding a proxy model for Z3, I realized that the proxy model is too complex and that there are many risks associated. And I've decided to go back to a more traditional model with checkins/checkouts. I'll be presenting that at EuroPython tomorrow.

Laptop stats at the Zope sprint in Europython

Here are some stats about the laptops used by the zope sprinters in Europython:

13 Apple notebooks (all of them 15'' Titanium btw)
5 Dell notebooks
1 IBM X40 subnotebook
1 ASUS S5 subnotebook (mine :) )
2 no-name notebooks (MITAC)

All the non-Apple notebooks seem to be running some variant of Linux (no Windows in sight).

Some of the titanium seem brand new, and all their owners seem to be proud of using the "world's most advanced obsolete computer" :)

JSR 170 (Java Content Repository) and Zope 3 ECM

I'm at the Z3ECM sprint in EuroPython 2005 and I've spent yesterday trying to play with the JCR (Java Content Repository aka JSR-170) trying to understand

how easy it would be to how a Zope content management system into a JCR (short answer: not easy - despite of claims of interoperability, JCR is a 100% Java technology).
if there are useful ideas in the JCR that could be put into the design of the repository for Z3ECM (short answer: probably, yes)

Hooking Zope into a JCR

After installing Jackrabbit (an open source implementation of the JCR made by the Apache project) and testing it with some Java examples, I've trying calling it from Python using the JPype Java<->Python bridge.

Installing Jackrabbit is not that hard, it took me about one hour though since I haven't done any Java development since 1996 and didn't have all the right tools (including Maven and a dozen of libraries like xalan, xerces, log4j, etc.) from the Apache Java project installed. Not a big deal anyway.

Unfortunately, JPype is pretty much a work in progress, that would benefit from more users and developers. There are, seemingly, limitations that prevented me from login in the JCR so this experiment didn't succeed and my knowledge of Java is much to light to keep on the experiment.

If we succeed in hooking Python/Zope into a JCR (which is, overall, just a question of Java/JNI knowledge and grunt work), I think the most important question is how the to make Zope and Java transactions systems work well together (transactions are an optional JSR-170 feature, but I don't see how a repository without transactions would be useful at all).

Ideas from the JCR specs

A JCR is a repository of nodes stored in whatever you want (flat files, SQL DB, object DB, XML DB...). Nodes are just collections of properties, so it's a very data-centric model that doesn't impose a programming model, and would work very well outside of Java. In practice, Nodes are the documents you're managing with you application. Nodes can be accessed from a path (hierarchical navigation, something Zope developpers are very familiar with), or by UUID (unique identifiers). More interesting are:

Querying nodes, which is based on a simplified XPath query language, or, optionally, a variant of SQL
XML import/export, which would provide interoperability between repositories at list in the sense that you can import data from one repository to another (no vendor lock-in)
Versionning
Events

Overall, nothing very different from what we are already doing with the CPS Repository (from CPSCore), but it's interesting to try to dig a bit further in the specs and to keep then in our minds when designing the Z3ECM model for the repository, querying, and versionning.

Related standards

The WebDAV/DeltaV standard for versionning and its JCP interpretation (JSR-147) are related to these specifications.

Slides for my "Python for middleware scripting" talk yesterday

I did a presentation yesterday at the ObjectWeb consortium architect seminar about "Python for middleware scripting" (trying to push Python to a Java crowd - not that easy). The slides are available (PDF, 800 kb). If you have comments on the slides (which were written in a bit of a hurry without the time to check all the information), I'd be glad to hear from you (-> sf@nuxeo.com).

Software patents: there is little time left (2 weeks), it's time to act now

Here is a message I just got from FFII regarding the upcoming vote on software patents in the European Parliament.

If the Directive is adopted in second reading by the Parliament, it would mean a tremendous blow to the european IT SMEs (and probably also some of the major players too) as well as for free / open source software projects who will have to sustain in the near future vicious attacks from our american competitors (and probably some others).

It seems there is still a little hope left, so we'd better not lose the last chances we have to change to course of the european IT history. It's time to act now.

Here is the mail:

Dear Stefane Fermigier, CEO, Nuxeo,

1) The vote in the Second Reading on the software patent directive is in 11-13 work days, on 5-7 July.

2) Lobbying in Brussels is heavy, currently there is much pressure on MEPs by pro-software-patent companies. The pro-patent lobby has about 30 lobbyists more than we, mostly wearing the hat of SMEs.

3) Your action is needed, at http://noepatents.eu.org/ we maintain a list of what you can do as an SME and as an individual. Especially we advise to see your MEP soon and, if you can speak for an SME, to visit the Economic Majority conference 29 June Brussels http://www.economic-majority.com/konf050629/. Please decide to come the conference early, so that a date with your MEP or with his/her assistant can be arranged in advance.
With kind regards,

Hartmut Pilch, G�rald S�drati-Dinet, FFII

Nuxeo against software patents

Here is a text that I've just written in support of the latest campaign against software patents in europe.

At Nuxeo, we are developping, with other european and non-european companies, world-class software in the field of Enterprise Content Management (ECM), a field currently dominated by american companies like Documentum, OpenText, IBM or Microsoft. These companies own a certain amount of patents that may or may not cover parts of what we are doing with our software, and may or may not be "bogus" patents, i.e. patents that would be invalidated by prior art. Finding out the patents that we may infringe upon, and and then trying to find evidence of prior art, would however take us so much of our own time, and of outside experts fees, that it would probably stop us from keeping innovating and distract a lot of our energy from our customers projects.

On our latest project, we have calculated that all the checks, audits and insurance fees needed to cover some of legal risk would amount to increasing our costs by 30 to 50%, with absolutely no benefits in terms of added value for our customers.
So, if these american companies are allowed to extend their software patents on the european territory, and since we are gaining market share at their expense, we are almost certain that they will use their patent portfolio against us in order to try to regain their market position.

We strongly believe that our situation is not an exception, but rather the general case, and that all european software companies have a lot to lose if the Software Patents Directive is adopted in its current state.

(Added at 17pm) My testimony is now online on the Economic Majority site, alongside other fine people like Pierre Haren (Ilog) or H�kon Wium Lie (Opera).

See the news on cps-project.org.

I'm really happy.

CPS 3.3.3 soon to be released

CPS is almost ready for a new major development release. I'm going to spend some times this week-end to test it thoroughly, but right now it seems to be a killer.

With the CPSSkin / CPSPortlet integration and the port of the old boxes-based portal configuration to the new system, we now have an awesome tool to customise the look and feel and the user interface of a CPS instance.

CPS 3.3.3 will be deployed next week in a variety of our projects, including our own intranet, cps-project and a new nuxeo.com.

Paris Zope3/ECM/Five sprint: the wrap-up

Here is the wrap up for the sprint that just happened in Nuxeo's premises in Paris this week.

As you can see, a lot has been achieved, though what has been done is slightly different from what was envisionned in the first place.

The good news is that we now have a better understanding of how we're going to gradually and non-disruptively shift from Zope2 to Zope3, thanks to Five and the upcoming Zope 2.8 release.

Status of the different projects:

Five/2.8 integration:

Martijn: A release (pr1) should be available soon on Codespeak with 2.8 + Five + ZX3.0.

This is the result of the work of many people.

We will followup on zope-dev mailling list.

We haven't solved the release management issues (coordination with Andreas Jung and Zope Corp).

We'd like to release 2.8 by mid-april, but it is not sure if it's going to happen.

Stefan: all tests (5459 of them!) pass for Zope 2.8 + Five.
RDF:

Michel: Tarek has added a bunch of test cases to Zemantic.

We've added text indexing to the litteral object values by backporting Zope 3.1 text indexes.

I'me going to do a 0.5 release as a result from the sprint.

Tarek: I've integrated Zemantic in our webmail. At this time it is used to replace a regular ZCatalog for search in body and headers, but the next step will be to set up more complex relations like : "give me the mails from bob written in the foo list about this subject" and zemantic has now everithing needeed to do so. It now deals with thinking about a efficient UI.
Repository/versions:

We've chatted about this between Zope, CPS, Silva and Plone hackers. That's all - not enough for a press release :).
CPSSkins:

Currently, I have implemented global portlets that can be dragged and dropped.

Only dummy portlets have been created. This is very simple to do.

Rendering (without any optimisations) is much faster than Zope 2.
Workflow

Julien: I have checked the WfMC engine made by Jim Fulton in a branch of the Subversion.

I have started implementing something on the third day of the sprint. I have created a utility that maps between documents and process instances.

The advantage of this model is that we could have something as simple as DCWorkflow for modeling the process definition. But we can also use all the power of the activity-based workflow for complex business applications with relations between different content objects.

I'm going to write a more complete description for what I have done and send it to the zope3-dev mailing list for comments.
Directories:

Florent: directories are a model for what an LDAP or a SQL directory is.

I've checked-in into the ParisSprint repository some code. There is no UI yet but I'm working on it.
Forms:

Sidnei: I've made a prototype to convert AT schemas to Z3.

There are local utilities in Five.

All of the CMF and Plone tests pass with 2.8 after some fixes.
A new release of CMF (1.4.8) has been made.

i18n:

Martijn: we've discussed some use cases.

The branching situation is now:

Five has two branches: trunk (must stay compatible with 2.7) and Zope 2.8 integration
We're doing a preview or an alpha today and our goal is to have a 2.8 release in 1 month.

Brevets logiciels: "racket du si�cle" et "d�marche quasi mafieuse"

La Mozilla Foundation abandonne le d�veloppement de "Mozilla Suite"

Tristan Nitot explique pourquoi il n'y aura pas de Mozilla 1.8. (Bon le titre est lui-m�me trompeur, car, selon l'article, le d�veloppement de la suite sera sans doute repris par des d�veloppeurs ind�pendants de la Mozilla Foundation).

Autrement dit: la Foundation abandonne la suite int�gr�e, et se concentre sur la s�rie de composants (Firefox, Thunderbird, Sunbird) et sur XULRunner, qui devrait r�soudre tous les probl�mes actuels. Peut-�tre...

Personnellement, tant qu'on retrouve dans la suite de composants les m�me fonctionnalit�s que dans la suite int�gr�e, pourquoi pas. Mais j'ai quand m�me quelques doutes.

En vrac:

A l'heure actuelle (ce n'est a priori pas bien compliqu�, mais en tout cas ca ne marche pas pour l'instant), il n'est pas possible d'ouvrir un lien dans un nouvel onglet depuis un mail.
Obligation de configurer les diff�rents composants ind�pendamment les un des autres, et parfois de configurer deux fois la m�me chose.
Alors que la lecture des flux RSS et ATOM est clairement une tendance tr�s forte � l'heure actuelle, celle-ci se fait de facon tr�s diff�rente dans Firefox ("live bookmarks") et dans Thunderbird.

Bref, on peut comprendre les arguments techniques et financiers qui poussent la Foundation � cet abandon, mais l'int�gration, ca a aussi du bon.

Brevets logiciels: tr�s bonne interview de Michel Rocard sur 01net

Michel Rocard explique et analyse l'adoption par le Conseil des ministres europ�ens d'une position commune sur le projet de directive. Selon lui et en conclusion "(...) cette pagaille juridique n'est bonne pour personne." et un compromis entre la Commission et le Parlement finira par �tre trouv�.

Esp�rons que ce sera le cas. L'avenir des cr�ateurs de logiciels europ�ens est � pr�sent entre les mains du Parlement.

Sprint Zope3/ECM: c'est dans une semaine

Derni�re semaine de pr�paration avant le sprint de la semaine prochaine. Une bonne partie du gratin mondial des d�veloppeurs Zope/CPS/Plone/Silva/Five... sera pr�sente chez Nuxeo, et la plupart des soci�t� et organisations leader du secteur ont d�l�gu� un ou plusieurs d�veloppeurs. C'est une opportunit� particuli�rement excitante pour tout le monde ici.

Eric ( Zope 3 Sprint in Paris : starting the Z3 ECMS effort) et Paul Everitt (Z3 ECMS effort starts) sont en pleine discussion, par blogs interpos�s, pour pr�parer le sprint.

Une des id�es �mergentes est d'int�grer RDF au coeur de l'architecture du projet ECM/Zope3.

Brevets logiciels: nouvelle menace s�rieuse

Nouveau rebondissement dans l'affaire des brevets logiciels: la Commission Barroso tente un nouveau passage en force, contre la volont� du Parlement, de son projet de directive, aujourd'hui 7 mars.

L'AFUL vient de sortir un communiqu� sur le sujet: La d�mocratie europ�enne bafou�e par la Commission Europ�enne.

MAJ � 11h35: le Danemark va semble-t-il s'opposer � ce nouveau passage en force. L'appel au gouvernement fran�ais pour qu'il se pr�occupe du sujet avec moins de m�pris l'int�r�t g�n�ral (et en particulier de l'innvation technologique, de la libert� de d�velopper et d'entreprendre, et dans l'int�r�t �conomique de l'Union) n'en reste pas moins d'actualit�.

MAJ � 14h: le Conseil a vot� la directive en d�pit de son r�glement int�rieur. La France n'a �videmment pas boug� le petit doigt.

LiveCD ERP5 disponible

Lu sur la liste ERP5, la version 1.0rc2 du liveCD est disponible.

Nexedi ne propose l'image ISO que par BitTorrent, j'en ai rendu une copie accessible par FTP et HTTP.

Le liveCD ERP5 permet de tester ERP5 sans se prendre la t�te avec toutes les d�pendances.

We are happy to announce the release of the second release candicate of the ERP5 Live CD. Please assume that this is a test version. You should expect that the Live CD is still unstable and can lead to massive data loss, although we have made a lot of effort to make it robust.

This version is available only by BitTorrent: http://bittorrent.com/

Once you set up BitTorrent, you can download the image file from this URL:

http://torrent.erp5.org/erp5-1.0rc2.iso.torrent

After you get the file, you can burn the image into a CD-R or CD-RW.

If you have already tried the previous version, you will have to remove the folder "erp5cd" and remake it. Otherwise, the Zope Products won't be freshed correctly.

Note that this Live CD requires some free space on your hard disk in order to store data in a permanent location.

Please read carefully the file "readme.txt" in the CD, before booting. Here is a list of known bugs in this release:

A few titles are still not appropriate

Japanese translation is incomplete

InventoryBrain is broken

Upgrading Business Templates is buggy

We are going to solve these problems in the next release. If you find any other problem, please send bugs to the mailing list

Jakob Nielsen: 10 usability heuristics

Un vieux (semble-t-il) papier de Jakob Nielsen, qui pr�sente 10 principes fondamentaux d'ergonomie des interfaces informatiques.

--

Visibility of system status: The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.
Match between system and the real world: The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.
User control and freedom: Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.
Consistency and standards: Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.
Error prevention: Even better than good error messages is a careful design which prevents a problem from occurring in the first place.
Recognition rather than recall: Make objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.
Flexibility and efficiency of use: Accelerators -- unseen by the novice user -- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.
Aesthetic and minimalist design: Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
Help users recognize, diagnose, and recover from errors: Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.
Help and documentation: Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user's task, list concrete steps to be carried out, and not be too large.

Transparents sur l'utilisation du logiciel libre � la DGI (Direction G�n�rale des Imp�ts)

Excellente pr�sentation de Jean-Marie Lapeyre, directeur technique du programme Copernic � la DGI.

Le logiciel libre, par sa modularit� et son respect des normes et standards, permet de r�pondre aux axes strat�giques du programme: ma�trise et p�rennit� du SI, ind�pendance vis-�-vis des technologies et des fournisseurs.

01net: L'open source veut forcer le barrage des PC

Lu sur 01 net:

Bien souvent, ces entreprises ou administrations pr�f�reront une d�marche progressive, o� l'on changera d'abord les applications bureautiques avant d'envisager, peut-�tre, la migration de l'OS, r�put�e plus complexe et plus exigeante.

Plusieurs soci�t�s se sont sp�cialis�es sur la promotion de ces solutions, telles StarXpert ou Nuxeo, qui a cr�� une structure d�di�e, Indesko. Cette derni�re s'est sp�cialis�e dans les prestations de conseil en migration autour de la suite Open Office et du navigateur Mozilla.
Pour St�phane Fermigier, le PDG de Nuxeo,� la perc�e est encore timide, mais elle est r�ussie. Le poste libre n'est plus un tabou d�sormais, parce que les applications ont �volu� rapidement. Bon nombre d'entreprises utilisent de fait des logiciels libres en bureautique sans strat�gie particuli�re. �

Article int�ressant sur xml.com:

In this article, I'm going to explore some of the ways that OpenOffice.org's Writer application (I'm using version 1.1.2 on Linux and 1.1.3 on Windows XP) is open to customization and configuration. I'll walk through some of the techniques I used to set up the first templates I built with the application in my quest for an interoperable, XHTML-ready system of templates and styles which will work across Microsoft Word and Writer.
