Meet during the Open Source Summit in Prague

2017/10/16

Getting approval for my participation at that conference was the toughest I ever had in the past, but I’ll be there again after having spoken in all the previous editions.

This time, this presentation will be made by a duo, as I’ve worked since the last LinuxCon EMEA with the FOSSology project to help them adopt a Continuous Packaging approach and Michael Jaeger from Siemens who leads the project will be with me to cover the topic. On my side, I’ll explain how project-builder.org was used, the setup done with Vagrant and containers to generate packages for 7 different Linux distributions (ongoing effort as we speak ;-), automating fully the production of packages as part of the LinuxFoundation build infrastructure for FOSSology. And of course the changes I had to make to the code to better support the project needs !

So I’ll be back in Prague (no problem as I love that city !) next week, to celebrate also the 10 years of project-builder.org, just after my week at DockerCon which is really starting today !

Meet at DockerCon Europe

2017/10/12

This is a late announce, as I wasn’t sure to be able to attend the event, but now everything is on track and I’ll be at DockerCon Europe next week ! One of my proposals has been selected as a 20′ session in the Community Theater and I’m glad as this is the first time I can participate to DockerCon. Project-Builder.org is using Docker since September 2014, so I’ll be able to celebrate the 3 years of Docker usage in pb after the 10 years of pb itself 😉 More seriously my goal is to promote again Continuous Packaging and demonstrate how beneficial it has been to introduce Docker in the chain, and how my upstream projects, as well as FOSSology are benefiting from it. Come to see that !

Of course, HPE is a platinum sponsor of the event so if you’re one of our customers, I’d also be happy to talk with you around your Docker projects as HPE is sponsoring my travel there ! (Thanks to the management to support again this despite hard times for travel requests and the HPE Next plan). Maybe I’ll still have a job when I’m back … or not 😉 Anyway, will see later as I’m now busy preparing my slides and demo for DockerCon among other stuff. See you there !

10 years of Project-Builder !

2017/09/24

Well, I think it’s worth to celebrate that milestone ! I’m now publishing officially the version 0.14.6 of project-builder.org for its 10th anniversary.

Everything started to solve an issue I had when I took over the maintenance of the MondoRescue project. It was very difficult in 2005 to consume the project. People had to download a tar file, follow a very succint recipe to build and install it and then being finally able to use it. The tool was supporting a lot of Linux distributions, but was difficult to use by these same distributions. So I started to build some shell scripts to help me deliver Linux distributions packages to solve that. I realized that I was duplicating stuff to address Fedora and RHEL, SuSE and SLES, Mandrake and Mandriva, … Even when building for other types such as Debian and Ubuntu or Gentoo. Typically all these distributions want a summary, a description, dependencies, changelog, … And I hate duplicating stuff. Also I realized I wasn’t the only one in need of this type of support. LinuxCOE, a peer project at HP was also in need of this, as well as many others.

So in 2007, I decided to rewrite my scripts in a more powerful language, perl (thanks Larry Wall ! and BTW I continue to find it way superior to a lot of younger ones, calling themselves more modern :-)). And version 0.5 was soon published as I used my vacation that year to code a lot for it.

It was way before I started to blog, and blog about it was among the first articles I decided to write. Of course, along the years, features have been developed, capabilities extended. I’m now able to generate project-builder.org it self and MondoRescue for 130 tuples of distributions. THat’s a proof this is possible, and that a tool like that can help achieving it.

10 years ago, I had to invent a configuration file format to support my needs. I wanted to have the least possible number of hard coded elements in project-builder.org. I created my own format, pretty simple mimicing the perl hash being: keyword param = value[,value]. At that time, YAML and JSON weren’t that popular, and I wasn’t aware of perl modules to support these, despite the fact they were existing, and my knowledge of CPAN wasn’t that accurate.
But at least I had inheritance mechanisms, and fucntions to deal with it, whch proved to be extremely useful to migrate.

So It’s now time, for the next 10 years to adopt a format, nearly as simple as mine, as easy to map to perl hashes as mine, and I chose YAML, benig lazy and finding it easier to manage manually (like mine was). Of course, this will have some consequences, as some old build environment don’t provide it so I may drop support for some very old distributions. If needed BTW something can be done as we have the source !! Version 0.15.1 is already in progress, and project-builder.org is now able to build itself, including in VMs or Docker containers for other distributions using that new format. And due to the mechanisms in place, I’ve kept easily all the features, just moving to a new format. I’ll start to work soon on migrating the conf files of MondoRescue to have another project working with that version. I’m also working in HPE with another team that is starting to use it as well, and I chose to adopt for them the new version to benefit from the way forward.

Finally, as I mentioned previously, the tool is now in use by the FOSSology project as well in the Linux Foundation build infrastructure. With the latest version 0.14.6, now FOSSology builds at least native packages for CentOS 7 on a CentOS 7 platform. Now we’ll work on the generation of packages for the other distributions the project want to support (which will be pretty easy now the infra is in place), in order to cover the topic during the Open Source Summit in Prague in October, providing I get approval to travel there (as I’m traveling quite a lot these days).

So happy birthday to project-builder.org and let’s start working on the next YAML based version, and help more projects adopt it !

Meet at SUSECon 2017, Prague

2017/09/16

As the sessions I proposed for the event weren’t accepted, I considered I had no chance to attend this year SUSECon. But it turned out that there was a need for HPE to have someone able to talk about Helion OpenStack on the booth, and I have been chosen to do it, so I’ll be around this year, for the first time, from the 25th to the 29th of September, in the beautiful city of Prague (will be my 4th time there !).

I’ll look forward meeting with some of my SUSE friends over there, and discover a new event.

Of course, as usual feel free to come and talk to me (I should be on the HPE booth when it’s open) of OpenStack, SUSE CaaS (as we’re working on a Reference Architecture on Synergy) and of course Open Source in general, and early music in particular 😉

It’s been a while

2017/09/12

When I look at the date of the last post, indeed it’s been a while since I took time to write here.

Many reasons to that, I took time off this summer to lead the infrastrcuture track at the RMLL, then to make music, for the 28th year in a row with 3 concerts and a diaporama, to visit Normandy with part of my family (Caen, Rouen, the Bayeux Tapestry, Honfleur, and many other places), back to work for some days and then doing another concert with the Variations ensemble I lead around François Ier in Monêtier les bains.

Then back to work. On top of my normal activities for HPE, I tried to incorporate various fixes into MondoRescue to finally publish 3.3.0, but that has again been delayed 😦 It seems I have a hard time publishing it, despite getting good patches or making them myself. I destroyed a system while doing tests, which forced me to update to Mageia 6 published meanwhile to put it back on track ! That didn’t help, and also I now need to check again but in VMs to avoid that issue and fix it for good (was too confident my modified code was working, but I was obviously wrong !). This is linked to fixes in mindi in order to fix size of initrd and its automatic computation. THat should be part of 3.3.0 as a consequence.

In order to solve support for multiple GPG keys signing my packages, I’ve had to go back to project-builder.org, and enhance it. Which lead to the publication of 0.14.6 (still not fully finished, despite code being frozen). And also I had work during my vacation time on chaging the format of project-builder.org conf files, from our own, to a YAML based one. For now, it’s just a change in format, not a semantic one, but that ill allow to improve some aspects, and also I get for free a syntax analysis with the perl YAML.pm module, which is nice (add -v to get the conf file concerned). So version 0.15.1 should come soon, once my 2 main users outside of myself won’t complain about bugs anymore.

One of these projects is FOSSology, and I should present the joint result of our common work with Michael Jaeger on the build infrastructure we put in place for the project to do Continuous Packaging at the upcoming Open Source Sumit in Prague in October, but it seems HPE doesn’t want to support my trip (I still didn’t get travel approval yet) and I may have to pay for it myself for the first time since I started talking at this conference back in …Prague in 2011. If you know anybody who would sponsor me, that would be great !!

Speaking of conferences, I’m this week at the Open Source Summit in Los Angeles, as part of my HPE job, where I lead a round table this morning on containers (are they the future of IaaS ?).

So despite having been quiet for long, Ive been busy as usual, and trying to improve the software I’m contributing to, andour global ecosystem, as well as the musical one. Hopefully you’ll get more news soon, as new releases and travel arrive !

First attendance to TuleapCon 2017

2017/06/30

Today, I had been invited to attend TuleapCon 2017. Ok, nothing to do with the Open Source Summit (formerly LinuxCon) with regards to size 😉 And it was just one hour drive from Grenoble ! But it was focussing on the Tuleap ALM solution, and was proposing customer testimonies so I was tempted to attend. Also because I know the CTO of Enalean, Manuel Vacelet, who demonstrated Docker to me during an excellent meetup he was leading and I was sure that he would again be very interesting to hear him expose the technology they develop.

And I wasn’t wrong 🙂 Some 40 people attended the event, testimonies were given by Airbus, Orange, CEA, ST Microelectronics, each time with very large user base and different use cases demonstrating the versatility of the tool. Also some integration work with other tools were demonstrated and explained.

What is impressive, is that today you can find such a company developing a solution and proposing it under the GPL. It’s so rare it needs to be underlined, and the spirit of the team is obviously influenced positively by that. Then they have some strong advantages wrt other ALM I’ve been able either to use or to consider: the methodolgy used to develop the software is a parameter of Tuleap. So you can decide to use a waterfall approach or Scrum or Kanban (the last one was unknown to me but the virtual posti-it dashboard sems not only nice but effective). And the other impressive aspect is that they do not only talk about automation, but they’re paranoid about it, and that’s really nice to see at that point in operation for software development.

So is everything nice and shiny. Well yes, but as with every powerful tool, you need time to become comfortable with it. At least that was my impression after playing a bit with it. I’m sure you’ll get rewarded, and I’m looking at the possibility to replace my old trac instance with it to be able to go further in the automation on my own projects. Not for tomorrow, but something to add to the TODO list 😉 (and no, you don’t want to see that !!)

Another nice aspet is their Open Roadmap offering: In short it’s a mutualization process to get features developed. And that’s not only clever, but again efficient. Of course, you need some large corporations to sustain the model, but that will alow at the end even more sharing around their platform by the users. More companies should adopt that.

And it was also interesting to see the work they are doing with StackStorm to enable a smooth cooperation between many automation tools. I think our Alexandria idea should be moved to this framework and benefit from all the existing integration. We would “just” need to add an iTop package to StackStorm, and a Redfish one, and most of what we try to do would be there.

BTW, the idea of combining the iTop CMDB and the Tuleap ALM to have a fully software defined and automated data center is really an apealing one. Will try to make that happen somehow 😉

So great day, learned a lot, so a useful day, lots of new ideas in mind, definitely worth the time, and if you want to experiment yourself, then attend the RMLL next week and we can all talk together as they will be around as well as myself ! And the last idea would be to convince them to use Continuous Packaging for Tuleap with Project-Builder.org 😉

Meet at the Open Source Summit NA 2017

2017/06/26

Despite difficult times for HPE, I’m still supported by my management to continue to represent HPE during tier 1 Open Source events such as the Open Source Summit North America, held in Los Angeles from the 11th to the 14th of September. Well, of course, because I was accepted as a speaker again !

I’ll lead a round table to cover with panelists whether “Containers are the future of IaaS ?

So as usual, if you are around, I’ll happy to discuss with you around Open Source in general, and the projects I’m involved with in particular such as MondoRescue (yes, there will be a new version soon, now remains to see the definition of soon), project-builder.org (same thing), Redfish, containers, early music or more.

Le logiciel libre en marche ?

2017/06/09

En dehors de la musique ou de l’informatique, J’exprime ici de temps à autre une opinion liée à la politique. Et comme tout français, les élections m’intéressent. Alors je me suis renseigné avant la présidentielle sur le site En Marche, pour savoir leur position sur le logiciel libre, étant intéressé par le positionnement européen, un certain nombre des idées et le comportement du candidat lors des débats. Et bien qu’il y ait une pleine page consacrée au numérique, rien sur mon sujet favori 😦 J’ai envoyé un mail sur leur plate-forme mais n’ai pas reçu de réponse (je suppose que la demande était plus grande que la bande passante disponible pour répondre).

J’avais assisté en Mai à une très intéressante présentation d’Olivier Véran sur le programme, où j’avais été convaincu par les éléments (et notamment son raisonnement très clair sur le domaine de la santé qu’il connait visiblement très bien et les améliorations potentielles qu’on peut y faire), aussi bien que par le personnage, à l’image pour moi de celui qui n’était pas encore président. De plus, il a vraiment été actif à l’assemblée lors de son séjour comme suppléant de G. Fioraso.

Mais lorsque je lui avais de nouveau posé la question sur le positionnement d’En Marche sur le logiciel Libre, il n’avait pas pu me répondre (ce que j’avais trouvé plus honnête que de me mener en bateau !).

La campagne candidats.fr reprenant, j’ai regardé sur le site et constaté que comme souvent beaucoup de signataires étaient FI (60+), Verts, PC, Pirates, mais peu LREM (9 ce soir).

Donc, ce soir, je suis retourné à la réunion publique d’Olivier Véran qui se présente pour la première circonscription de l’Isère (réunion aussi intéressante que la précédente du reste au passage) et lui ai demandé s’il était prêt à signer le pacte du logiciel libre, après avoir resitué cette question.

Il m’a dit l’avoir vu passer dans ses mails, que son site en utilisait, que Mounir Mahjoubi, secrétaire d’État chargé du numérique en était un partisan également (mais tout le monde ne semble pas nécessairement d’accord avec cela) et qu’il était donc favorable au soutien. Il a immédiatement signé le pacte et j’ai envoyé une copie sur candidats.fr qui pourra ainsi mettre le site à jour. Qu’il en soit ici remercié !

Je pourrai donc maintenant le recontacter pour parler avec lui autour de certains aspects de l’économie du libre, des libertés numériques dans notre monde ou du droit d’auteur, ce qui fermera la boucle vers les arts et la musique, dont notre nouveau président semble être aussi amateur.

Espérons que cela représente les prémices d’une politique ambitieuse en matière d’adoption des logiciels libres, au moins au niveau de l’état et des collectivités locales, pour favoriser l’emploi peu délocalisable et les sociétés de services locales, ainsi que des économies substantielles au vue de la place de plus en plus grande occupées par le logiciel dans nos environnements. Ce n’est pas plus une utopie que les autres réformes qui semblent vouloir être menées. il y aura du bien et du moins réussi sans doute, mais je sens une volonté d’oeuvrer pour le bien public. Et quoi de plus en ligne avec cette approche que le logiciel libre ?

Meet at the RMLL 2017

2017/06/07

This year the RMLL are coming back, from the 1st to the 7th of July and in my region, in St Etienne ! And this year, I am not only a speaker, but also a co-track leader for the Server track.

With my talks, You’ll be able to learn about the latest news for MondoRescue, project-builder.org, Docker, Redfish and python-redfish, Mageia and much more from my co-speakers (Ethereum, CMS, Cloud Native app, Unikernels, …) and even more from Keynote speakers as well.

Lodging is now available, so book quickly and let meet us there !

Un septennat d’attente

2017/05/14

Lors de la première à Ambronay en 2010, je ne savais pas qui était Falvetti. Je n’étais pas le seul. J’aurai sans doute dû faire confiance à Leonardo Garcia Alarcon déjà présent dans de nombreux disque de l’Ensemble Elyma de Gabriel Garrido. Et puis j’ai écouté le disque paru en 2011 de ce “Il Diluvo Universale” et ce fut un coup de massue : Comment avait-on pu ignorer une telle oeuvre depuis 1682 !!

Elle a pour elle l’énergie, des lignes mélodiques si facile à mémoriser qu’elles s’imprègnent immédiatement dans l’esprit, des effets prenants, une histoire singulière (celle de Noé). Bref tout pour plaire. Surtout, quand un tel chef se l’approprie, en donne une vision engagée, avec des chanteurs complètement en phase avec son approche. C’était décidé, il fallait aller vérifier en concert que cela était bien réel, et ressentir cette musique en direct, éprouver les émotions dans la salle.

Seulement voilà, bien qu’elle fût souvent redonnée à Ambronay, cela ne collait jamais avec nos contraintes, d’autres concerts ou ceux que nous faisions, et je désespérais de pouvoir le voir le temps passant.

Aussi quand j’ai vu en Mai 2016 que l’oeuvre était de nouveau programmée à Lyon pour Mai 2017, j’ai sauté sur l’occasion, réservé les places et bloqué la date. Et bien cette semaine, après 7 ans d’attente, j’ai enfin pu entendre cette pièce à l’Auditorium Maurice Ravel. Certes, ce n’est pas la meilleure acoustique du monde, mais finalement, étant très bien placé en orchestre, on pouvait capter tous les détails (quels archiluths !) et profiter des inflexions des voix de façon très précise. Une mise en espace était faire pour rendre l’histoire plus présente, simple et de bon goût.

La prise de rôle de Roberta Mammeli en Rad a été somptueuse. Le trio avec Magali Arnault Stanczak et Emmanuelle de Negri fait mouche et chavirer la salle. Il faudra le bisser. Du reste le chef nous a gratifié de 4 bis, ce qui n’était que justice (pour nous !) au vu du succès obtenu, que l’on peut vraiment qualifier de triomphe. Les vois de femmes dominent complètement pour moi la distribution. Le Noé de Fernando Guimaraes est noble, mais manque un peu de conviction, ou de puissance pour s’affirmer d’avantage. La Mort de Fabian Schofrin est bien grimée, mais son chant n’est ni agréable (ce que l’on peut comprendre pour un tel personnage) ni prenant. On regrette un Dominique Visse qui serait parfait dans ce genre d’emploi.

Mais vétille ! Les percussions de Keyvan Chemirani apportent un plus indéniable à la musique, sans la trahir, et rendent les danses virevoltante. Bravo au chef pour cette résurrection et surtout de continuer à faire tourner cette production pour que de nombreux autres spectateurs puissent la voir.

Si seulement les organisateurs de la MC2 pouvaient s’inspirer de leurs voisins et convier ce spectacle dans l’auditorium, ce serait une vrai perfection sonore combinée ! A bon entendeur …
