FOSDEM 2017 : our impressions

Packed amphitheatre for the keynote on the «Kubernetes on the road to GIFEE»

In the 2017’s FOSDEM event, held in Brussels, Soizik, Cécile, Clément, Adrien and Andreas represented Savoir-faire Linux. Here, they share briefly their experience and impressions from their participation in the event.

Soizik Froger, project manager

It was my first FOSDEM event, and I loved it. I have only one regret: I wish I could have attended every session, and talked with everyone!! It was a tremendous place for tech-savvy and free software lovers like me. Seeing those panelists with very high level of expertise has taught me a lesson about humility that comes with great knowledge.

I definitely give five stars to Frenchy Matthieu Totet’s talk on Graph Cycles. This is a passionate work on a real time graph on Twitter and how we can seize the fantastic potential of this technology!

I almost cried of joy at open Q&A session with members of the OpenJDK Governing Board: Mark Reinhold, Mario Torre, Andrew Haley, Georges Saab & Doug Lee (embedded). I secretly took a picture, and I’m sure I will keep it in front of my eyes until the next FOSDEM.

I give the best ‘orator palm’ to Christian Thalinger for his benchmarking of Compiler JIT Graal on Twitter services. It was such a clear and organized speech that a slow guy like me understood it all.

Finally, I discovered what technologies lie behind Ring. Our session was a great success. We were excited by the volume of the turn-out. We had a diverse and enthusiastic audience that posed questions about the architecture of Ring and its ambitious potential for scalability. High five to the Ring’s development team!

Cécile Delépine, Delegate Europe General Manager

That was my first FOSDEM too! It was a great opportunity to meet with the industry in a both cozy and professional environment.
My main focus was containers orchestration with Kubernetes, the fast growing Open Source community at the time being. FOSDEM is the place for technological intelligence, which I see as a BizDev not as an engineer.

Students and tech-related senior job seekers, please take note : FOSDEM is also a place for hiring talents (we invaded FOSDEM job corner with all our job posts for France and Canada). Our presentation on Ring , and Clement’s commitment to LemonLdap coupled with our presence on OW2 stand also significantly contributed to promoting our expertise at Savoir-faire Linux.

I wish I attended Mozilla conference too. What does motivate the open source community? This is the question posed by Rina Jensen, whose conclusions should be widely shared.

Some food for thoughts.

My five stars goes to Software Heritage, a project supported and initiated by Roberto Di Cosmo (INRIA, GTLL Systematic Member). The source code of our projects is a common good, thus it should be available to all and be centralized in one archive which does not depend un one solution and does not vary from one solution to another (Github, Bitbucket…)

Last but not least, I bought the book How Linux works and I almost finished the second chapter;-)

Clément Oudot, infrastructure and security expert

This year, I represented LemonLDAP::NG projet. I then met with Fusion Directory and Spoon communities., It was the first time we had an OW2 stand, and it showed that this consortium was not only Enterprise oriented but also community-oriented.

I was pleased by the large number of attendees at Perl stand and the packed Devroom.
I am still surprised to see Perl can attract so many people. What a wonderful turn-out for Perl!

During this weekend, I met with lots of people I knew from different communities : Framasoft, XMPP, OpenStack, VLC, PHP etc. That’s why I love going to FOSDEM!

Ring conference : What technologies lie behind Ring

Adrien Béraud, Ring system engineer
FOSDEM is an exciting and inspiring place. We met with lots of interesting people with interesting projects, There were too many people! [8000 people attended the event]

As for the Ring session, it was amazing to see how exciting the audience were. Last year, people discovered Ring, this year, they wanted to know a lot more about the technology. No wonder there were so many of them. Actually, there is a growing interest for distributed communication systems.

My five stars goes to Alok Anand, who presented Telepathy Connection Manager for Ring. He was able to develop it because he joined Google Summer of Code’s program which accommodated Ring from Savoir-faire Linux. Thanks to such a wonderful collaboration and such a nice program for young coders.

Andreas Traczyk, Ring developer

Like Soizic and Cecile, it was my first time at FOSDEM in Brussels. It surpassed all my expectations. There were so many passionate people, so many nerds in the same place;-) It was intense!

A packed room for Ring conference

I was really impressed by the turn-out of the audience during the Ring session, Although we did not haveso much time, we were well received, and the audience’s questions were challenging. Besides, I wish we had more space and more time!

My five stars for the best presentation goes to Daniel Pocock for his excellent talk on the real time communication solutions crowdfunding. It was so interesting, so inspiring.

Ring being listed among Free Software Foundation’s High Priority Projects

Becoming integrated into GNU since November, since 2017 Ring has been listed in Free Software Foundation (FSF)’s High Priority Projects (HPP) .

The main objective of HPP initiative is to increase Free Software reputation and adoption among information systems users, individuals and/or corporations. Since 2005, the foundation updates a list of work in progress applications for contributors, volunteers, companies and other Free Software supporters. Without their help, those projects would have never reached their full potential.
This list addresses several issues of Libre technologies such as decentralization, security, mobile APPs or real time voice and video chats. Ring is presented in this last category.

To FSF’s mind, the present context of mass surveillance forces us to fulfill Free Software commitment: creating new alternatives and secure solutions to proprietary communication softwares.

Ring’s presence in the HPP list is very important. As a Free, decentralized, secure and universal software, Ring fits natively in FSF’s philosophy because it is distributed under GPL v3 with its code being open to all contributions.

An object of study

Namely, our development team works with external contributions and academic partners. Ring is already part of computer engineering undergraduate programs at École Polytechnique de Montréal. This winter, new functions of Ring will be taught to 3rd year students.
Besides, let’s not forget to mention the important contribution of Université du Québec à Montréal (UQAM) graduates in building a secure Distributed Hashed Table system for Ring.

Therefore Free Software Foundation’s support nurture our will to share our own developments of a Free, universal, secure and distributed software project, which takes part in building a decentralized and free Internet.

Tuleap: The Platform of Our Choice for Developing the “Ring Project”

Last November, our Ring development team met with Enalean’s. This company develops Tuleap, the software development project management tool we use for Ring. Here is the story of our relationship with Tuleap.

I’m Guillaume Roguez, the Technical Manager of the Ring Project at Savoir-faire Linux HQ in Montreal. Savoir-faire Linux is an Information Systems’ (IS) solutions provider highly specialized in deploying, customizing, integrating, and strategizing the best-in-their-class free/libre and open source software (FLOSS) tools and projects to respond to unmet clients’ business needs. Our vision is to be the front-runner in the field of IS/IT technologies that are developed, extended, supported by, or connected to FLOSS underlying technologies. To realize this objective, it is our mandate to be and remain creative, innovative and continuously R&D-oriented. Ring is one among several other in-house R&D projects that we have launched and maintained.

In brief, Ring is a free, distributed and universal communication software published under the GNU General Public License version 3. Ring allows its users to communicate in multiple ways using it as a telephone (i.e., VoIP), a media sharing tool (i.e., exchanging videos), a messenger (i.e., exchanging texts) or as a building block for your Internet of Things (IoT) project. Ring can be seen as a FLOSS alternative for Skype.

My responsibilities are to manage all technical aspects of the Ring project, and coordinate the team members’ tasks. I also present Ring Project through giving public speeches at different universities in Montreal (e.g., Université du Québec à Montréal, Polytechnique -Université de Montréal, McGill University, École de Technologie Supérieure, etc.). We have also used Ring as a research subject, a living lab, for graduate students here in Montreal. Students have had the chance to hone their programing skills while contributing the the progress of the Ring (e.g., Google Summer of Code). In fact, it is very important for Savoir-faire Linux to collaborate with university-based research centers and student-researchers in order to expand the limits of the community around the project. .

To continue, I wish to take the opportunity to briefly touch upon the technical environment – Tuleap- that we have chosen to rely on. Put simply, Tuleap is the software development project management tool that I can recommend; It facilitates our collaborative work; it saves us a lot of time; and it helps us organize all our daily affairs.

Our Journey from Redmine to Tuleap: Challenges and Opportunities

At the beginning of the Ring project we used the same technical environment that we would use for most of our current projects at Savoir-faire Linux, i.e., Redmine. However, having used Redmine for the Ring, we soon realized that it was not the right environment. Redmine has a quite rigid design which does not allow the users to easily adapt the tracker fields to their specific usage. Overall, Redmine is quite limited and restrictive. Making modifications in the tracker, for instance, requires several manipulations and once they are done, you cannot easily change your mind. I always wanted something more flexible for my team.
For me, GitHub is oversimplified and a lot of features are missing; and again, it is too rigid. Although, from the design perspective, it is full of eye candy , it is still too expensive in the long run. It may be the right tool for a small or even a medium-sized project; nonetheless, GitHub’s restrictive design rapidly limits the capacity of an Agile-oriented management team. You have to adapt your work flow to the tool and not the opposite. Therefore, that’s a no-go for us.
If one uses Git in Tuleap environment, there is the possibility to force the work flow to perform a particular action. One may view this as a limitation, but in reality, such possibility can educate team members to adjust their actions towards the right direction in conformity with of the project. Tuleap is not a self-dependent tool. On the contrary, Tuleap’s underlying design – which is very plug-in oriented – provides the development team with the possibility to interact with other well-established free software tools such as Git and Gerrit. As an example, we can force Git commit messages to contain a reference to the related issues in Tuleap. Later, we can couple this functionality with Git to more easily browse and have a complete and customized tracking system.
These advantages of Tuleap have been clear from the onset to our Chief Technology Officer Jerome Oufella. He proposed adoption of Tuleap and explained his reasons. To be honest, when someone tries to implement a change so fundamental to a team’s work flow, some frictions are naturally expected. But, our past experiences have shown us that the flexibility level of team members slowly but steadily increases as they move along the learning curve. Indeed, there is always a price to pay for any change management.

Among other challenges, we faced the issue of missing documentations. This was a bump on the road as we could not easily set up our trackers and fix bugs as rapidly as we should have. Luckily, Tuleap’s core development team was receptive to our feedback. They helped us design a setup tailored to our needs and benefit from the flexibility that enabled us to add and change our tracking details. Tuleap’s setup has this quality that evolves with the user’s project. The more we used this flexibility and evolutionary nature of Tuleap, the more we gained confidence in the decision we made to adopt Tuleap.

Last but not least, Tuleap is an open source tool embedded in a very dynamic and vibrant community of developers. For instance, just last month (January 04, 2017), Tuleap released a new version (9.3) with the first steps of the brand new query language for the tracking system. This will enable developers to make advanced searches within the Tuleap trackers as it supports the “AND”, “OR” and “()” characters. We’ll be able to get all the tickets matching with complex queries such as : (summary = “tracker” OR summary = “query”) AND submission = “language”.

I think a frequent visit to Tuleap’s website is worth the try because: a) there are easy-to-understand video and text-based tutorials; b) all information regarding the newly added features and bug fixes are clearly delineated; and c) it is a window to connect to the Tuleap’s community, to ask questions and engage in a technological discussion.

Our Current Agile Experience with Tuleap

We have been developing Ring under the Agile Software Development Methodology. Using, the Tuleap Scrum planning release helps us to track and monitor bugs and enhancements, the wiki and the forums efficiently. We coupled it to Gerrit code review system for the patches management .

On the day-to-day, there are about 10 developers from Savoir-faire Linux using Tuleap to develop Ring. I will be there too- wearing several hats as: project/technical manager, developer, and the Scrum master. We can add to this group of motivated developers all the other community members (platform maintainers, users, followers, etc.) who are dispersed around the globe and help one another to progress of this innovative community-based project.

Keeping an Eye on Tuleap…

Quite recently, November 2016, I had the opportunity to personally meet with Manon Midy from the Tuleap core development team at the Paris Open Source Summit. Some of my colleagues and I had the chance to share our opinions about the things we wished to improve or be different in Tuleap. Perhaps the most important among all was the user interface. Right now, there are too many clicks to be made in order to get done what you intend to do. Furthermore, the User Interface (UI) is quite complex. Having heard from Manon that the team was already deeply engaged in the activity of “re-thinking the overall design” was absolutely heartwarming. Finally, as shown by the track record of Tuleap’s new versions and up-to-date releases (9.2 and 9.3), we trust that it is a highly promising and dependable project for generation of software developers to come.

Ring on UWP : genesis of a technical challenge


Ring’s beta 2 version  is now available on the Universal Windows Platform (UWP). It’s not only a great step forward for Ring, an official GNU package, but a technical success for our development team.

This release of the beta 2 is the work of collaborative development between Savoir-faire Linux and the community of developers all over the world. Ring is still a work in progress, that’s why we invite all users- passionate or curious- to test our secure and decentralized multimedia communication platform and give us some feedback.
Since November 2016, Ring is part of GNU, this mile stone marks our involvement in the Free Software philosophy, for its purpose – the free access for all – as much as its development, where every contribution counts. Ring’s universal dimension, with distinctive aspects such as decentralization through OpenDHT, follows its path in the communication software industry, and it has to be available in UWP.
With this new platform, Microsoft’s goal is quite simple : all application developments will be unified, even if the client’s applications are on different devices, such as desktops, tablets, Surface computers, smartphones, Xbox or IoT. The developers‘ job is easier, the application’s code will need to be written only once, with some minor modifications to deploy it in different terminals. For our development team at Savoir-faire Linux, it is an opportunity to get in touch with all Microsoft users. « It offers a lot of potential; Ring could be used on Windows phone, Surface laptops, tablets, or games console such as Xbox, explains Guillaume Roguez, Ring development manager at Savoir-faire Linux.

From a closed system to open software engineering

At Savoir-faire Linux, as you can presume, we are not used to working with Windows environments, hence this was a big challenge for our team. Developers Andreas Traczyk and Nicolas Jäger took on the challenge from the very beginning, until this awaited release.

The genesis started during the first term of 2016, with a prospection phase and a feasibility study. Andreas Traczyk took on this mission,  porting the existing Ring code to Windows. Gradually, an idea arose to Andreas and Nicolas : why not use win32 already created to adapt it for UWP?


Coding in C++/CX

However, the challenge got bigger, with the choice of the language. Whereas a majority of Windows developers use C#, both Savoir-faire Linux developers chose C++/CX. The first reason was the daemon, which is in C++, «it shall be wrapped to have a C#», explains Andreas Traczyk. The second reason is a pragmatical one, according Nicolas Jäger. « Ring is above all a multimedia software, with video, audio and real time network, and the C++ code allows for resource optimization». This practical choice has been approved by Cyrille Béraud, Savoir-faire Linux president, careful about «the application’s performance standards».

For us, whose core business is Linux code, we had to go off trail, get out of our comfort zone. « Loving complicated things is a way of life» grins Nicolas Jäger. As much as we did not only tackle the User Interface (UI), but also some fundamental parts, simply because they didn’t exist before».

To Guillaume Roguez, Ring’s development manager, it was a positive experience, «because we overcame obstacles, and the first was very colossal: starting from scratch. We tried and succeeded in developing free software in Windows’ universe. »

Free software development is our motivation through Ring. This project benefits from Montreal universities contributions, from Polytechnique Montreal to École de technologie Supérieure. One of them, Université du Québec à Montréal, works to improve the data persistence and indexation in its underlying distributed hash table software library, OpenDHT, with the help of professor Alexandre Blondin-Massé and his graduate and post graduate students. This confidentiality and security issue ignited more than a spark of interest among cybersecurity specialists, throughout the world.
As a Free Software Foundation and Linux Foundation partner, Savoir-faire Linux is an active member of the Free Software community and works towards resources availability, creating and diffusing users value. As a common goods producer, we claim the right of each user to have a free access to knowledge as much as free and universal resources.
Hence the importance of Ring’s release in UWP, because its takes part of  Free spirit.

Blockchain, a revolutionary tool for Ring

social-network-sphereBlockchain technology brings on a new revolution, as its advocates write on every wall, it is likely to deeply change our verticaly-shaped society.  Savoir-faire Linux uses its mechanism to develop Ring distributed ledger and users ID management.

Blockchain is the technology on which Bitcoin is based. This digital cryptocurrency displays both fear and covetness among the financial sector. However, beyond bitcoin, blockchain offers other exploitations, thanks to its decentralized, anonymous and secure operation. In addition, it reveals governance challenges, which can tumble organizations as we’ve seen them for decades. That’s why blockchain is one of the major issues of the 2016 Paris Open Source Summit, November 15th and 16th.

A decentralized society, without trusted third parties

There is no doubt about it : blockchain technology will have as much as an inpact as the invention of the web. According to its promoters, this technology is more than a tool, it will change the shape of society, towards a more decentralised one. Blockchain will overturn the trusted third party concept, if not remove it.
Blockchain works as a big public ledger, which registers every transaction between users. This large database is shared by all of them. Their identities are systematically verified by asymetric encryption. The transactions are put in a block, encrypted and certified by the network’s node – composed of other users aka miners- the block will be added to the chain and distributed through the network to all users.
The blockchain’s fundamentals are distintermediation, traceability and distributed consensus. As they are organized in decentralised nodes, users act as a validation authority. Hence, the transactions are traceable in the public and shared ledger. The distributed consensus lies in the following fact : every node receives the same chain of timestamped data through this huge ledger, and what’s more, every change has to be approved by a majority of miners.
Blockchain was born where cryptography and decentralised networks meet. The 2008 financial crisis and the lack of confidence towards banks were its breeding ground. Besides Bitcoin, created by Satashi Nakamoto, whose real name is not yet publicized, several trustless architectures have been set up. Among them, Ethereum is one of the most widely used. This non-profit foundation has a blockchain based system, which takes up the ID ledger and unforgeable history to execute any sort of code, called «smart contract»

Blockchain, a fundamental tool for Ring

Savoir-faire Linux’s team of experts has used Ethereum technology to include encryption standards in the creation of Ring’s database The smart contract is therefore the public ledger of names associated with a RingID, which is created by the application. As in every blockchain «each link depends on the previous elements to ensure the security of the database and to make it unforgeable» explains Adrien Béraud, Systems engineer, in charge of developing the distributed hash library OpenDHT.
Blockchain integration in Ring’s public key directory follows Savoir-faire Linux’s guidelines : to preserve the distributed network as Ring puts it, to ensure security with encryption keys and to let the user opt in or opt out of the public ledger. « This option offers the user the possibility to register or not the database and only use his RingID to communicate onto the network» details Adrien Béraud.
The smart contract coding is key. Given the fact that the decentralised registry is optional, users can preserve their pseudonymity through its RingID, which is then not associated with an alias or a username. Some smart contracts failed, because the code revealed some errors or vulnerabilities. Ring’s development team at Savoir-faire Linux tries toavoid any risk by following a basic principle: «we try to write a code with a simple design, with great care».
«Furthermore, we put the focus on a thorough QA, code review and we rely on external outputs», he concludes.
Contribute to Ring’s succes as well as Blockchain philosophy by coding with us!

Ring Bêta 2 is now available


Ring, a GNU projet, is improving. Test the Gaston Miron version now! Distributed under license GPLv3, Ring is available on GNU/Linux, Windows, Mac/OSX, Android and soon on iOS and UWP (Universal Windows Platform).
Among the latest features in the beta 2 version, you will find:

  • A global account identification mechanism based on blockchain implementation on an Ethereum technology.
  •  Multi-device
  •  IPv6 support

Compatibility break

All users are invited to go to beta 2 due to a compatability break with the older version. Ring will handle the migration very easily.
Ring as a communication platform can be used to develop various projects: videoconferencing and distributed collaboration, IoT or robotics !

An active development process

We are continuously  improving Ring, in order to offer the best of communication to its clients. The software is in the active development phase and we invite the Free Software community to take part in this audacious project. All new ideas are welcomed to help its evolution.

Ring, officially a GNU package


Since the month of October, Ring is officially a GNU package, following its integration into the GNU project.

Distributed under the GPLv3+ license, Ring is a free software which enables communication in multiple ways between its users. It is a phone, a conference station, a platform for exchanges and media sharing, and a link for the Internet of Things, all in a world where freedom and security go hand in hand. Running on a distributed network and encrypted from end to end, Ring tries to provide to Ring users’ a high level of privacy and confidentiality.

In the mid 2000s, Savoir-faire Linux has started a project called SFL Phone. The project then evolved to produce another: Ring. This shift is marked by various milestones such as the transition from SIP server to the OpenDHT distributed network in 2014, permitting decentralized communication, peer to peer mode. Becoming a GNU package is a new venture for the project and the free software movement.
Thanks to external contributions, which are the cornerstone of the Ring project, the Savoir-faire Linux team has over several months developed a beta 2, which fits perfectly with the philosophy of free software. Beyond the code, Ring has established links between the development team and the local partner universities such as the Université du Québec à Montréal (UQÀM), Polytechnique Montréal and the École de Technologie Supérieure (ÉTS ) which is home to the Maison du Logiciel Libre (ML2).

We want to thank all our contributors, all of whose assistance was greatly appreciated.

Savoir-faire Linux, is Gold sponsor at the Liferay Symposium 2016

We are very happy to announce our presence to the community, our partners and clients at the Liferay Symposium 2016 which will be held in Chicago at the end of the month.

An Intensive Weekend about Ring

Over the last few months, Ring – under the GPLv3 licence – has created an effervescence in the free-source software, hacker and cybersecurity world, although it is only in its beta version.

Many Internet and industrial operators of telecommunications, and the sustainable development industry are showing close interest. Presented in the plenary at FOSDEM 2016 in Brussels a few weeks go, Ring will be a major topic this weekend simultaneously at the FOSSASIA conference in Singapore and especially during the LibrePlanet Conference in Boston organized by the famous Free Software Foundation that will celebrate its 30th anniversary.

cyrille-beraudOn this occasion, Cyrille Béraud, the President of Savoir-faire Linux, will present in greater detail Ring, to better understand what free-software is and why, as many specialists are murmuring, this software can be a milestone in Internet’s history.

Can you explain to us what Ring is exactly?

Firstly, I would like to let you know that Ring is an open-source software, therefore it is a common good. From a functional perspective, the public will discover it as some sort of Skype or Hangout.

Ring allows to establish an encrypted video, audio, very high quality text communication between two or many people, no matter where they are in the world. It is available on Linux, Windows, Mac/OSX, and Android platforms and within the next few months on iOS. It is distributed with its sources under the GPLv3 licence.


However, I would like to bring particular attention to the fact that Ring is still a young software that remains fragile and that in numerous situations will not function perfectly, even at times not at all. This being said, it is improving every day and in an standard environment and for domestic use, it functions very well.

But what distinguishes Ring from other softwares that have the same functionality?

Ring allows to establish a peer-to-peer communication without passing through a central server. That is the determining point. Ring is firstly a distributed communication platform. No need for operators, to manager servers, no more costs associated to each of your calls all the while Ring offers more freedom and security. In a professional context, many companies can benefit from its flexibility and important economies. For everyone, it is the possibility to communicate freely at no cost no matter where, in securely manner.

Technically, we have based ourselves on already well proven technologies : ffmpg/libav, GnuTLS, pjsip, etc. However, regarding the innovation at the core of Ring, we have used the concept of DHTs, Distributed Hash Tables. We have developed our own library, OpenDHT, only available on Github, by introducing important innovations, when joined with ICE and SIP protocols, allow to cross the routers, firewalls, to localize, in a certain manner, a user or an equipment, even if it is found in a private network, and establish, if one possesses its contact’s user identification, a highly secure communication channel in real time, anywhere in the world.

reseau-papineauBecause of this feature and the fact that Ring uses open and recognized standards, this platform allows to sketch a truly universal non hierarchical system of communication on the Internet, while allowing not only one communication between two people, however more generally, between two or a multitude of objects on the Internet. From this point of view, the innovations that we have made available through Ring, open numerous possibilities and industrial applications to the public. We already have in our laboratory, many prototypes based on very light embedded platforms, that from Ring, can interconnect with home automation or data acquisition systems. It is quite spectacular and very promising.

To complete this overview, it is important to note that Ring functions in degraded mode and even while being completely disconnected from the Internet. Imagine an isolated village in Africa or in India with a poor connexion. In case of a disconnection to the Internet, Ring’s distributed system, will retract itself on its nodes that it can reach and can continue to work. In the example where the village is disconnected from the world, the residents can continue communicating amongst themselves. From this point of view, Ring can participate in sustainable development and contribute to the economy and democracy of a country that does not have a developed communication infrastructure.

You see, Ring has a lot of potential! And to make Ring and its underlying technologies available to a greater number of people, to allow each and everyone through the world to invent their own usage of Ring, it had to be a free software.

Is there an economic model behind Ring and can you briefly introduce Savoir-faire Linux?

Of course there is an economic model behind Ring! It is the one of free-software. We create use values that we make available freely to everyone. These use values create an economy of services. This economy, open and competitive, creates a lot of value of course. In the case of Ring, Savoir-faire Linux will have its place. This economy is based on exchange and collaboration. This is the business model of Savoir-faire Linux. It opposes itself to the economy of windfall and the appropriation of wealth by a small number.

To conclude, Savoir-faire Linux is a Canadian service company based in Montreal, with teams in Quebec and Toronto, even in France, in Paris. We also have a presence in the Ivory Coast through a partnership.

With our 110 engineers, all of very high level and all specialized in open technologies, we are present in the defence and embedded electronics sector, in the banking sector, with Desjardins our client, as well as in the insurance sector, the software engineering sector with the Canadian Space Agency, the management information sector with the Organisation Internationale de la Francophonie and supply numerous local enterprises.

We also have, and it is essential for us, to create strong ties with the worldwide actors of free sofware. I am thinking specifically about the Linux Foundation, from who we distribute our trainings and to our Open Source partner editors, such as RedHat or Liferay. We also have many contributions in free projects, such as the Linux core. Behold, in summary, what is Savoir-faire Linux.

Savoir-faire Linux is the ambition to create wealth through values. We don’t always succeed. But every day, over the past 15 years, we continue to add value our work with two passions that reside in us : liberty and excellence.

Ring – Welcome to Beta

RingRing is improving to deliver the best communication. Test the Papineau version now! More practical, stable and simple, this beta includes news functionalities, especially thanks to the support of the community.

More practical, stable and simple

Ring has evolved significantly in recent months. Savoir-faire Linux’s team has solved hundreds of bugs and improved overall robustness. To propose this beta, it added new features, such as video group calling and chating outside a call. It also developed a version for Android and maximised the video quality.

The support of the community

Ring is a project that received the support of contributors from around the world, particularly to translate its interface. Through the collaborative platform Transifex, everyone can proposed word sequences in his language. Ring is thus available in English, French, German, Spanish, Portuguese, Russian, Ukrainian, Arabic and, partially, in Lithuanian and Esperanto.
