How to to bring voice and video capabilities to intercom solutions using SIP-based software

IoT, Embedded Edge & Open Hardware, Makers

IP video intercom systems combined with smartphones can leverage regular RTP/SIP VoIP technology to offer a new set of services to end-users: getting a notification when visitors press the door bell, seeing them on video before answering the call, interacting with them before opening the door, at home or anywhere else via wifi or 3G coverage.

The Linhome app (a free SIP client), Liblinphone (a VoIP SDK) and Flexisip (a proxy server) can be used to build a complete VoIP network. These software use open standards to reliably send the audio and video streams captured from IP video intercoms to in-house devices, including smartphones and tablets, connected either to a local network or to the public internet.

This lecture will describe how they can be used together to build an embedded SIP network dedicated to home automation or video surveillance. The network architecture used in these contexts can also be deployed in other areas, such as the emergency services or the Internet of Things.

Open-Source: Open Choice – A DevOps Guide for OSS Adoption

Cloud, Multicloud & vendor free, DevOps

Choosing the right open-source project to use can be quite challenging – not knowing if it’s going to be the right fit, how it will behave, and if you end up wasting time trying to make it all work. We’ve all been there.

But what if I told you there’s a practical way to have a clear understanding of how to incorporate an OSS project in your environment?

In this talk, I’m going to speak about the DevOps perspective on open-source and the challenges Infra-focused engineers have with choosing the right project for their environment.

As a DevOps Engineer, I’ve seen a lot of things, stumbled upon a lot of non-based decisions, and so will present practical advice on how to choose an OSS project for your dev/prod environment and will talk about the business mindset you should have to evaluate the key indicators based on your needs and specific pain points.

DS in public authorities

Economic models, community sustainability and financing

When in 2020 the DINUM (Inter-ministerial digital department) decided to no longer open its simplified formalities portal demarches-simplifies.fr to local authorities due to a lack of business model and the capacity to organise this large community, it handed the project over to ADULLACT.
The association therefore opened its own platform, demarches.adullact.org, for use by local authorities.
The creation of this new DS (data server) instance was the opportunity for a big clean-out of source code which up till then was dedicated to the sole instance of the DINUM (clean-out = deletion of hard-coded data in sources!). This clean-out opened the door to other instances in the clean rooms of local authority groupings. In this way, the public interest group ARNIA (Bourgogne-Franche-Comté) created its own DS based on the ADULLACT model. Others followed, such as Gironde Numérique, ALPI, CDG59, Somme numérique, etc.
But ADULLACT also introduced the notion of collaborative development with the DINUM, to implement new functions specific to local authorities. The aim: not to diverge!
To sum up, in this way we have created a new community around open source DS software.

Digital commons and social economy structures

Economic models, community sustainability and financing

The renewal of commons enabled by digital technology exists at the junction of two environments that until now were heterogeneous: open source software and the social economy (ESS). The reconciliation of digital commons and open source software highlighted the difficulty for open source digital projects to ensure their economic sustainability without altering their nature of commons; while the social economy offers structures that develop innovative and non-capitalistic business models in line with the characteristics of digital commons, namely collective ownership and shared governance.
Also, it seems timely to question the relevance of social economy structures (associations, mutual insurers, cooperatives) to structure a business model that will ensure the viability of open source software while guaranteeing their digital commons nature.
A discussion may be possible after the presentation.

End-To-End Performance Testing, Profiling, and Analysis at Redis

Cloud, Multicloud & vendor free, DevOps

High-performance (as measured by sub-millisecond response time for queries) is a key characteristic of the Redis database, and it is one of the main reasons why Redis is the most popular key-value database in the world.

In order to continue improving performance across all of the different Redis components, we’ve developed a framework for automatically triggering performance tests, telemetry gathering, profiling, and data visualization upon code commit.

In this talk, we describe how this type of automation and “zero-touch” profiling scaled our ability to pursue performance regressions and to find opportunities to improve the efficiency of our code, helping us (as a company) to start shifting from a reactive to a more proactive performance mindset.

“Less is more” or how to regain control of your systems

Sustainable IT

Today, IT is facing three major issues: cyber-security, sovereignty, hardware & energy sobriety.

These issues originate in very widespread development methods, which seem simple and fast, but which create opacity and hide the calculation processes, so well that in truth the systems cannot be verified, even when the business logics that these calculations produce are often quite simple.

The solution? Simplify, reduce, break apart…to understand.

The bases of current systems were thought up around 50 years ago for very limited machines: minute amount of random-access memory, very slow read-only memory, very slow processors. These limitations have no sense today, everything needs to be rethought.

The Minimacy open-source project opens a new pathway by applying the principle of “Less is More” to IT development.

The association created in 1985 by Coluche has not always been a fan of open source software. In this conference, I will offer my feedback on this transition, which occurred seamlessly.
I’d like to start by explaining how the IT department functions in an association such as “Les Restos du Coeur”. I’ll speak about the specifics of the department in terms of businesses or local authorities. To understand why this project was conducted in such a way.
So, I’ll offer an initial overview before the launch of this ambitious project to free up the Restos du Coeur association. I will also explain the relationship that the association had with proprietary software, the needs of the association outlets and why it decided to reverse its path and move to fully open source.
Users have not been ignored, in fact the opposite. They are the ones working on the IT tools, so it was vital to take into account the target audience to deliver relevant solutions that could be understood by all. Obviously, changing habits has not been without its sticking points and I will explain what caused issues and how (with which tools) I was able to resolve them.

Planned sustainability vs. planned obsolescence

Sustainable IT

Over 90% of computers that are scrapped still work. They have simply become obsolete because of the software. We have all been faced with the need to have the latest version of a program, which only works on a recent release of the OS, which can’t be installed on an aged computer. And if you replace the computer, you often need to buy new peripherals because the drivers for old ones aren’t available any more. Thanks to Linux and open source software, the lifetime of our computers can easily exceed 10 years. But you might still need to replace a broken monitor, a faulty keyboard or install more memory! Why! was created in 2013 and was the first to propose repair guides on ifixit.com.

Landscape of Open Source eXplainable AI libraries

Data transformation, ML/AI, web3, distribution, analytics

Machine Learning raises novel concerns about how well we understand vastly deployed models. Beyond trust, safety is at stake; can a system deployed in production be guaranteed to work without any proper understanding? The answer is no. The field of research of EXplainable AI (XAI) is dedicated to providing methods that make the behaviour and predictions of machine learning systems understandable to humans.

Many open-source tools are available, each having different degrees of maturity and algorithmic capability. It ranges from an algorithm implemented by a single person for a paper, to a highly maintained tool from a large company. Those libraries are numerous and it can be hard to find which one fits best your usage while understanding the intricacies of the specific explanations provided.

For this presentation, I’ll be your tour guide providing a grid to analyze libraries and highlighting some of the most promising XAI libraries along with some insightful examples.

Open Source, the appropriate response to societal and environmental issues

Sustainable IT

At a time when the IPCC has given us three years to change our behaviour, where global inequalities are becoming deeper, digital tech is soaring with increasing energy demands. Human interactions, mutual assistance, eco-responsibility, eco-design, accessibility, local economy, data sovereignty, negative growth, are terms we are seeing increasingly and which are undeniably linked as they concern OUR society.

Open source, common property? A product of our society, still under valued and yet it’s a true resource to address the challenges we face currently!
But to do so, it still needs to be adopted!
So come and find out why open source can address current issues in this 20-minute talk!

Adding OpenTelemetry to Production Apps: Lessons Learned

Cloud, Multicloud & vendor free, DevOps

Observability is increasingly important in our modern apps/cloud-native world. However, when adding observability to existing production apps, there are a number of tradeoffs in approaches and in tools. Often, these tradeoffs are an exercise in confusion, leading to decision paralysis.

We took on the challenge of adding observability to NGINX MARA, investigating choices, discovering and addressing challenges while keeping to open source solutions whenever possible.

Come learn from our experience in dealing with OpenTelemetry and related tools, from traces, metrics and logs, in working with production class apps and discover what approach finally worked for us.

DGFiP and its major project to modernise computer calculations

Business Apps and Work Solutions

Two years ago, a major project to modernise the computerised coding of income tax assessments was initiated at the French government’s Public Finances Directorate (DGFiP). The software at the heart of the modernisation project is Mlang, a compiler written in OCaml for a dedicated language pair used by the DGFiP to encode income tax calculations. For two years, the DGFiP has worked on integrating Mlang into the official income tax calculation infrastructure to replace the ageing systems. The project therefore has a very high impact (€80 million per year) and close to R&D (OCaml, open source, innovation)! The aim: retain the digital sovereignty of its calculation infrastructure.

Over the past 5 years, the market of content collaboration platforms has been shifting towards providing new features allowing to structure documents and enhance content through third-party integrations.

In the meantime, digital workplaces, which provide also functionalities around content (chat, video conferencing, emails) have been longly awaited to bring these innovations :

* Microsoft integrated a wiki module in Teams using plain data, letting external integrators selling enhancements over their system to structure the information

* Open Source solutions focus on raw content collaboration, and delegate structured content editing to office editors (Collabora, OnlyOffice)

Open Source is the future of financial services

Business Apps and Work Solutions

Money flows are at the heart of fintechs and marketplaces’ strategies: these companies must meet the needs of the market, their users and adapt to an increasingly competitive environment. This growing complexity and specificity goes hand in hand with a need for advanced customization of their payment infrastructure in order to perfectly meet their payment scenarios, their commercial offer and their strategy. Open Source is on its way to becoming the cornerstone of this new paradigm, unlocking and enabling new product and business opportunities. Today, the technical teams of these fintechs and marketplaces spend precious time building themselves. If tomorrow, the building blocks of these infrastructures and payment flows were available in Open Source libraries. This would allow all these money-moving businesses to combine these blocks with each other in order to create solutions that suit them, while being assured of the reliability and durability of the code used.

Measuring the environmental impacts of digital technologies : open source versus opacity.

Sustainable IT

Assessments have significantly contributed to the awareness of the environmental impacts caused by digital tech. Although efficient vectors of awareness raising, they drew attention to negligible actions such as reducing emails, an age-old subject in discussions on digital technology and the environment. If a measurement can orient understanding of the subject for the general public all the way up to management, you can appreciate its political dimension.

To face democratic imperatives, we propose that you consider the measurement of the impact of digital use as a commons to help it serve transparency, both in the approach and the results.

How to apply these concepts to the measurement of environmental impacts? What limits do we need to exceed?

We will answer these questions by modelling the impacts of a digital service using open source tools, data and methods.

Open Source Legal compliance : Hermine, one year after

Governance and OSPO

OSXP 2021 was the opportunity to announce the introduction of an open source community project “[Hermine-FOSS](https://hermine-foss.org/)”, corresponding to an open, shared and equipped approach to open source compliance.

By inviting organisations to collectively rethink the efforts required in terms of open source compliance (as opposed to individual management, often difficult to sustain), this project brought together five organisations in early 2022: Enedis, Inno³, Lectra, Orange, OVH Cloud and RTE.

The partnership led to the publication of an initial vision of the project under a GNU Affero GPL 3.0 license and a first shared database of open source license interpretations. All the resources are available online at Gitlab (https://gitlab.com/hermine-project/hermine). It has already been presented to the main open source ecosystems and industrial operators interested by these topics and/or active on technical components which complement Hermine (such as [OpenSource Review Toolkit](https://github.com/oss-review-toolkit/ort).

This panel will be the opportunity to gather the main project partners to collectively share a vision of the project, illustrate with main use cases, and present the next steps in structuring the project. We will also set out the main technical or legal advances made in 2022 so far and the respective roadmaps.

Implementation of OSPOs for our clients: lessons learned

Governance and OSPO

Today the use of open source has become essential for any company developing software.

To eliminate any risks, notably legal, it must nonetheless be supported by the creation of a governance body, often referred to as an OSPO (Open Source Program Office). The approach is to implement internal procedures, install a committee of legal advisers and developers, and raise the awareness of teams.

What must an open source policy contain? How to ensure that it is respected? Does it need to be appended to the internal regulations? How to manage the question of developer contributions to external Open Source projects? Who should be on the Open Source committee?

How to reconcile privacy and AI ?

Data transformation, ML/AI, web3, distribution, analytics

Today, most AI tools offer no privacy by design mechanisms : when data is sent to be analysed by third parties, the data is exposed to malicious usage or potential leakage. If we consider voice assistants, for instance, audio recordings are often sent to the Cloud to be analysed, leaving conversations exposed to leaks and uncontrolled usage without users’ knowledge or consent. So currently, even though data may be sent securely with TLS, some stakeholders in the loop can see and expose data : the AI company renting the machine, the Cloud provider or a malicious insider.

With our solution, data remains always protected as it is only decrypted inside a Trusted Execution Environment, called an enclave, whose contents are protected by hardware. While data is in clear inside the enclave, it is inaccessible to the outside thanks to isolation and memory encryption. This way, data can be processed, enriched, and analysed by AI, without exposing it to external parties.

European open source publishers are reporting notable growth and turning increasingly to the SaaS model. They explain how their open source approach differentiates them from major international publishers. Does joining together, like in the Euclidia alliance, or communities such as OW2 or Eclipse, make it easier to resist? How do they manage to adapt their business models to cloud subscriptions and managed services?

Open Source for biodiversity, the example of Hack4Nature

Open Models (open data, science, hardware, education)

And what if open source could help us deliver innovative and sustainable solutions to preserve species, restore environments and reconnect humans with nature? Last year, a hybrid international Hackathon was initiated to highlight the environmental problems and consider high-tech or low-tech solutions serving biodiversity. One single limitation, that all projects be open source and FAIR. The format brought together tech profiles that do not commonly work together: IT developers, data scientists, environmental researchers, biologists, ecologists, etc. Many projects were successful, each with their own governance! Some resulted in the creation of an association, others were funded to enable their industrial scaling-up. After the success of this first session, a Hack4Nature version 2 is under construction – come and join us!

Implementing Voice Assistants with Open Source

Data transformation, ML/AI, web3, distribution, analytics

Voice assistants are considered to be very intrusive in private lives. And rightly so: in most cases, voice and user behaviours use very powerful cloud services but which are also very opaque. However, voice assistants are very useful and deliver functions that improve the user experience. In a mobile context above all, their use has become almost unavoidable. In this conference, we will provide open source alternatives for the implementation of these voice assistant type functions. We will present a prototype based on several open source software components that you can also implement. An opportunity to present the operation of voice assistants and the technologies used in the background.

Feedback from 10 years running an opensource business

Economic models, community sustainability and financing

In the 10+ years that Oslandia has existed, the company has gone through multiple phases. Creating and driving a business that delivers services via open source software is attempting the impossible, and at the time of founding it would have been difficult to imagine the road ahead.

I look back over my personal experience over these last ten years of heading up a pure player in open source, mentioning a few points that have marked the changes in the company, the obstacles encountered and the sources of solutions.

Are you looking to get a foot in open source business? Is your business in this growing sector? I hope that sharing some episodes from my experience as an entrepreneur will help you manage your own adventure with greater peace of mind.

How digital public goods promote digital sovereignty

Issues, strategies and digital sovereignty

Digital sovereignty helps countries maintain control over their decision making and implementation of services. Digital public goods, a type of open-source solution, allow countries to adopt, adapt and scale technology in ways that maintain their flexibility. As uptake of digital public goods – and thus digital sovereignty – spreads, it is reshaping the patterns of development co-operation. Join this talk by the Digital Public Goods Alliance to learn more.

Virtual FabLab Cadracks

Open Models (open data, science, hardware, education)

The Virtual FabLab Cadracks project aims to develop and promote an open source digital platform for the collaborative design of complex objects (e.g. Vehicles, robots, machine tools, etc.) that is not currently available and therefore completely innovative.
Virtual FabLab Cadracks is a genuine opportunity and even a necessity in the current climate urgency to speed up several transitions:
• the energy transition by reducing the carbon footprint of international production processes of manufactured objects.
• the economic transition by creating or recreating a sustainable circular economy ecosystem.
• the digital transition by training audiences from FabLabs, production third places, prototype builders, creators, VSE, SME, etc.

The achievement of societal objectives is extensively subject to the choice of governance of the platform that we propose to re-question during this conference.

A case study of time-series forecasting for bike rentals with scikit-learn 1.1

Data transformation, ML/AI, web3, distribution, analytics

scikit-learn is a (the?) reference Open Source machine learning library used world wide by hundreds of thousands of Python data scientists.

This session introduces how to leverage scikit-learn’s powerful histogram-based gradient boosted trees on a practical problem: hourly forecasting the number of bike rentals in a given city at various times of the week, month and year depending on weather conditions and business cycles.

We will leverage various loss functions including some dedicated to quantile regression which allows us to quantify the uncertainty of each and every prediction of the model.

It will also demonstrate how to use pandas to easily build lag and windowing features. We evaluate the statistical performance of the models with time-series cross-validation tools and calibration methods.

This talk will come with a publicly available Jupyter notebook to reproduce the results of the experiments.

Having a live open-source industrial software around academic bricks

Economic models, community sustainability and financing

There are several ways of completing a technology transfer from an academic laboratory that is developing an open source component, to an industrial player. In the SPARK project, we opted to collaborate with academic communities, to be able to use them in a demanding industrial context and to help them adapt to satisfy the needs of our clients. These collaborative projects covering five academic components had to evolve according to the changes in the communities in question. I will present the different levels of collaboration in user, sponsor or collaborating party mode, the transitions we have made from one mode to another, and the challenges raised by this approach in terms of investment, sustainability and software quality. But also all the benefits for the project to be able to maintain technology components at the state of the art and for academic communities to interact with the users of their research results.
