Transparents intervention à Autour du Libre 2006 : “Résumé rapide de quelques travaux en Génie Logiciel sur le logiciel libre”

Je suis intervenu lors de Autour du Libre 2006 la semaine dernière à Brest, pour y faire une présentation rapide de quelques résultats en matière de recherche académique sur le Logiciel Libre, et plus spécifiquement du côté génie logiciel.

Je tiens à remercier Gregorio Robles qui m’a permis d’utiliser une grande partie des figures que j’ai présentées, qui sont issues de son mémoire de thèse de doctorat portant sur l’analyse du logiciel libre, qu’il a soutenue récemment.

Voici le lien vers les slides que j’ai présentés : en PDF, et le source en OpenOffice.org (attention, gros document). Update : une version anglaise des slides est disponible.

Accepted papers for International track of WFS 2006 in Porto Alegre

Share your keyboard and mouse between several computers : synergy

I just wanted to signal one very cool tool : synergy. It will allow you to share your mouse and keyboard between two computers. For example, I have a desktop and a laptop. Sometimes I have to work on the laptop and would like to use the desktop’s keyboard (much nicer for typing) and its mouse (instead of the touchpad of the laptop : less errorprone). Synergy allows me to switch from one screen to the other just by moving the mouse out of the bottom or top sides of the screens, without effort.

Really a cool tool. Thanks to Denis for letting me know of this tool. Eh, why don’t you give it a try ?
There are alternatives to this setup, like using VNC, but synergy can be very handful, and is pretty simple to setup. Hope this helps.

Wiki Picolibre de retour sur la toile

Le wiki de Picolibre a subi une panne indépendante de sa volonté. Il est de retour (en lecture seule pour les non-membres du projet) sur http://proget.int-evry.fr/portail/TwikiPage&wikiweb=Pftcr.Picolibre&wikipage=WebHome, hébergé sur la plate-forme ProGET (laquelle représente un point de référence actuel pour le futur de PicoLibre). Bonne consultation (oui, c’est très lent 🙠)

Motivation for contribution to libre software projects instead of free-riding

We have tried and emphasize the strategy that organisations can adopt with respect to the maintainability of the in-house applications based on libre software, in a previous paper. We profess that contribution is in no way mandatory, and free-riding is definitely possible for users of libre software. But at the same time, contribution to upstream projects may be one best way to ensure parts of the maintainance effort can be “outsourced” upstream. Still, it may not be an easy task anyway. For instance, it can be difficult to weight on the decisions of upstream developers and have your modifications integrated in the codebase.
It seems that we’re not the only one to have published on this idea recently. Similar arguments are given by by Kris Ven, Herwig Mannaert and Jan Verelst of University of Antwerp (Belgium), according to the presentation they have made at Calibre’s FOSDEM room : Participation of Independent Software Vendors in free and open source software projects (they also published a paper on the same subject). They argue from the standpoint of ISVs instead of an organisation who wants to use libre software for in-house needs, which was our case. But actually I was not much convinced that this were not two similar situations actually. Even though they may have developped the product as an ISV, that seems to be somehow a very custom-made product, and not one product used by so many different and generic entities. Maybe other cases of ISVs publishing more generic products may be more interesting to add to their point. Still, I’m sure that’s a very good finding anyway. I’ll try to keep an eye on bibliography for such pleas for contribution.
