2 Keynote, Luis Busquets, European Commission


view the speaker's video

The ICT domain is certainly the fastest moving sector in the economy. The late developments in the XX century seemed to bring a world where the step to produce new innovation would become locked to new entrepreneurs and only those controlling the previous innovations would be able to produce more. However, Open Source has changed this paradigm. Today, we see how Open Source Software has succeeded everywhere but in a way that was not foreseen neither by its advocates nor its detractors. The world is now in the verge of a digital industrial change and Open Source Software and Hardware will be game changers in this (r)evolution.

view the speaker's video


view the speaker's slides

The session objective is to present a cross-analysis of 28 EU country intelligence reports on the open source software ecosystem of each Member State, focusing on the public sector. The country intelligence of each Member State provides an overview of policies and existing legal frameworks as well as open source software initiatives. The session will focus on presenting a cross-country analysis of trends and strengths throughout the European Union and to share best practices. 
Some examples of key insights will be shared and will include, for instance, observations on the actors and representatives of OSS in the public sector; reflections on both legally- and non-legally binding policies and legal frameworks of countries through a benchmark analysis; showcases of the initiatives sorted by type and objective. Finally, the session will also include a short presentation of a country particularly active in implementing OSS and its path towards the recognition of OSS within its public administration to share best practices and lessons learnt.
The country intelligence reports were compiled through desk research and were shared with national contact points on OSS within the countries’ governments. They are published as part of the Open Source Observatory (OSOR) project of the European Commission.

4 Can end-users Apps also be Open-Source ?, Ludovic Dubost, XWiki SAS


view the speaker's video


view the speaker's slides

Open-Source is highly present. However, the competition in the end-user app space with Cloud providers is tough. A lot of proprietary solutions exist and are build on Open-Source libraries and technologies, but are not shared as Open-Source.

XWiki SAS is a provider of open-source collaboration apps (XWiki, CryptPad) for now 15 years living only off it's Open-Source technologies. 

How is it possible to develop Open Source end-user apps ? What are the challenges to achieve this ? How do you finance the technology ? How do you sell it ? How do you differentiate your software from proprietary solutions ?

This is the aim of this presentation, to share our experience and our history.

6 Towards a sustainable solution to open source sustainability, Tobie Langel, UnlockOpen


view the speaker's video


view the speaker's slides

A few years ago, Heartbleed epitomized a massive open source sustainability problem for critical parts of the internet infrastructure. The bug, which affected the popular OpenSSL cryptographic software library, notably compromised the confidentiality of 4.5 million US patient records and cost the industry an estimated $500M.

It was soon revealed that the root cause of the issue was that OpenSSL was precariously understaffed. Open source sustainability became a major theme overnight. Stories of maintainer burn-out made the headlines. And tentative solutions started to emerge, most of them donation-based.

In this talk we’ll explore a number of existing strategies to fund open source and make it more sustainable, from patronage to dedicated ad networks. And we’ll defend the idea that the best path to open source sustainability is to help companies understand the tangible business value they can get from contributing to open source.

8 Keynote: Software Heritage, a revolutionary infrastructure for software source code, Roberto Di Cosmo, Software Heritage / Inria


view the speaker's video


view the speaker's slides

Open Source Software is at the heart of our digital society and embodies a growing part of our technical and organisational knowledge, and this raises many questions: how to comply with the obligations of Open Source licenses? how to be sure that the source code of a key module we use will be still there when we need it in the future?  do we really know what source code we are using, and where it comes from? how can we adress cybersecurity if we do not know? how do we share this information across the software supply chain?

Answering these questions and answering them well is quite a challenge.

In this presentation, you will discover Software Heritage, an open non-profit initiative, in partnership with Unesco, and supported by major IT players, and how the revolutionary infrastructure it is building changes the way we adress these issues.

With 8 billions unique source files from 120 million repositories, it is the largest archive of source code ever built.

You can already access and use this infrastructure.

We now invite you to help it grow, and take part in its unique undertaking.

11 XWiki: A web development runtime platform, Vincent Massol, XWiki SAS


view the speaker's video


view the speaker's slides

When developing a web application, the traditional way is to develop the application from scratch using a general purpose language such as Javascript, Python, Java, Ruby, PHP, etc.

This presentation will show that a next generation wiki (examples based on XWiki: http://xwiki.org) can be used as a web development platform to develop applications on top of it, providing a strong  infrastructure scaffolding to building web applications.

The advantages are similar to those of using an application sever. However whereas an application server offers technical services only, a wiki platform offers higher level services such as content management, rendering, storage, WYSIWYGeditor, user management, and a lot more.

Not only are these services offered, you can develop using them in your traditional IDE or in the runtime, directly in wiki pages. This allows developing web applications extremely quickly, collaboratively and with a fast turnaround time, which is perfect for adhoc web application development.

view the speaker's slides

We propose a walkthrough of current utilization of Open Source Software in capacity planning for the Orange network infrastructure.
The objective of our project is to have a platform that helps engineers to carefully plan the resources available to them as well as to correlate different incidents within remote parts of the infrastructure.
In order to achieve this we started using Cacti with the Spine collector which worked great, but Orange France is a very large company with many entities, each with its own governance, and so we began to see some limitations.
There was a need to centralize some information from different parts in Orange France as well as to integrate the equipment capacity and load values into BigData Orange.
In order to achieve this we developed the “Puits de donneés” platform completely based on Open Source Software.
The visualization and statistical analysis part is handled by Grafana while the ETL runs on Apache Software Foundation products like NiFi, Zookeeper and Ambari with a storage solution from MariaDB for which we did extensive performance tuning and customization due to the large amounts of data.

20 Enabling DevOps for IoT software development, powered by Open Source, Hui Song, SINTEF


view the speaker's video


view the speaker's slides

We would like to share our research journey towards enabling DevOps for IoT applications, and how Open Source makes the journey feasible and fun. 

DevOps is widely adopted for developing cloud applications, which supports developers in continuously placing software changes directly to production. As companies are including IoT and Edge devices into their IT infrastructures, supporting DevOps for IoT is a must. However, IoT challenges some fundamental assumptions behind DevOps, such as the homogeneous infrastructure and centralized governance, and therefore, breaking-through research is needed. Funded by H2020, 30 people from 12 partners crossing academia and industry gathered to solve these fundamental challenges, which results in full-stack open source tools for automatic deployment, learning-based operation and security monitoring of IoT applications, and risk management of the development process. The tools are evaluated on industrial use cases in intelligent transportation, smart building, and eHealth.

The mass open source tools and communities around IoT development provides the sound foundation for this design research and the opportunities for the further exploitation of the results. In particular, we are proud of spinning off a start-up to commercialize the risk management services in the open source + SaaS model.

26 SW360 and FOSSology - A Team for License Compliance, Michael Jaeger, Siemens AG


view the speaker's video

FOSSology is an open source license compliance software system and toolkit. As a toolkit, you can run license, copyright and export control scans from the command line. As a system, a database and Web user interface provide you with a compliance workflow. License, copyright and export scanners are tools used in the workflow. FOSSology is license under the GPL, it is therefore available for anyone to facilitate license compliance tasks.

While FOSSology provides the license analysis for individual OSS components, the Eclipse OSS project SW360 is a software catalogue to provide a central place for managing and sharing license information about software components used by an organization. It is designed to neatly integrate into existing infrastructures related to the management of software artifacts and projects by providing separate backend services for distinct tasks and a Web application to access these services.

27 Ideas, methods and tools for OSS Compliance assessment, Boris Baldassari, Castalia Solutions


view the speaker's video


view the speaker's slides

While Open Source Software has become mainstream, the understanding of its key principles, from ethics and collaboration to governance and community management, is gaining more interest and attention. There is a comprehensive volume of studies and reports backing up our individual and collective experience, yet we still cannot reliably measure these characteristics, and even less clearly define or assess them.

In an attempt to build up confidence and foster maturity in this area, this talk will look at the various existing models and metrics related to OSS compliance and governance, and build upon them to propose methods and tools for their evaluation and analysis. We will discuss the requirements and essential questions to ask, offer guidelines for implementation and suggest efficient ways to present results.

view the speaker's slides

2020 has started intense for many countries. It's been just a few months, but the things we have lived make us feel like it's been years. Covid-19 pandemic has hit everywhere and forced many people to work from home. If you were lucky enough to be in one of these modern companies that have adopted digital transformation years ago, would that be a problem? Many people have thought it wasn't, but it has really been. And what about the rest of the software developers involved in companies not ready for remote work at all?

It's been said that nothing has boosted more companies' digital transformation than covid-19. But, are their managers ready for such change? Managing software development at scale is not an easy task, and this pandemic has disrupted the way projects are being developed in many companies.

During this talk, I would like to share lessons learned from open source development at scale that might help companies to adapt to these changes. But more specifically, lessons about how software development analytics help managers to understand collaborative remote work.

31 Open source contribution policies that don't suck, Tobie Langel, UnlockOpen


view the speaker's video


view the speaker's slides

Open source contribution policies are long, boring, overlooked documents, that generally suck. They're designed to protect the company at all costs. But in the process, end up hurting engineering productivity, and morale. Sometimes they even unknowingly put corporate IP at risk.

But that's not inevitable.

It's possible to write open source contribution policies that make engineers lives easier, boost morale and productivity, reduce attrition, and attract new talent. And it's possible to do so while reducing the company's IP risk, not increasing it.

In this talk, we'll look at the general structure of contribution policies, examples in the wild, and tactics to make them suck less.

We'll also look at how to turn these policies into self-service software, preventing the tedious email back and forth between engineering and legal in most cases and making open source contribution a breeze.

33 The NGI0 Initiative: Encouraging Adoption of FOSS Licensing Best Practices, Gabriel Ku Wei Bin, Free Software Foundation Europe


view the speaker's video


view the speaker's slides

The Next Generation Internet Initiative is a funding action organized by the European Commission. It is intended to provide funding opportunities to developing technologies and software that has the potential to improve the internet's potential to be a platform that supports human values, such as privacy, transparency, inclusivity, and the protection of data. The results of these efforts are intended to be eventually made available as Free Software.

The FSFE currently assists this Initiative, together with several other NGOs. The FSFE's role in particular is to encourage participant software projects to adopt best practices in displaying copyright and licensing information in their software projects. We estimate that the FSFE will have had to provide advice and guidance on how to properly display their license and copyright information to  around one hundred small software projects involved in this Initiative.

This presentation will talk about the NGI0 Initiative, the importance of proper license compliance, as well as share some patterns that we have observed on how developers of small, independent software choose to license their projects, and how they may deviate from best practices that can cause problems later.
