Open Source for Railways ? An SNCF example with OSRD

Mobility needs change regularly, affecting both people and goods. As each of these needs arises, the railway system seeks the best response. Several strategies can be adopted: changes to timetables, adjustment of the rolling stock fleet or changes or creation of infrastructure (increase in speed, introduction of new signal systems, new line or new product), etc. Each strategy often involves a considerable investment. It is therefore essential to compare the scenarios before embarking on such a project. This is where the operational studies come into play, which analyse each scenario considered. The quantitative and qualitative study of these different scenarios gives orientations and indications on their relevance. Railway simulations, whether static or dynamic, are therefore used to assess the appropriateness of carrying out a project, and help to make the most objective decisions possible. Each operational study can be based on different railway simulation tools available on the market. However, SNCF Réseau has decided to develop its own in Open Source: this has given rise to Open Source Railway Designer (OSRD).

The OW2 Market Readiness Levels method. A tool for IT decision makers

The growth of open source software is taking place in two main directions. On the one hand, by moving up the layers of the information systems, from the operating system to the business applications. There, open source software is increasingly used by non-computer scientists. Secondly, by becoming mainstream. The market is becoming commonplace to the point of reaching decision-makers who are unfamiliar with open source. For these new users, trained in the commercial practices of proprietary software sellers, open source remains a counter-intuitive model whose technical, legal and community specificities are a source of uncertainty. We need to speak to mainstream decision-makers in a language they understand. This is the role of the Market Readiness Levels (MRL) open source project evaluation method developed by OW2.

LibreOffice: Improving project sustainability

LibreOffice was announced in 2010. After 10 years, there was a need to review and update the strategy according to the evolution of the office suite market, in order to improve the sustainability model. Companies do not support the project as much as individual users. Over time, this can pose a threat to the sustainability of the project. We changed our strategy to educate companies on the right approach to free software, giving back to ensure the long-term sustainability of the LibreOffice project.

Choosing the right business model and license for your open source project to survive

When starting a business and deciding to use do it open source, it’s critical to know why you are doing so, what benefits you want from the open source approach. This session will help you select and manage the licensing aspects of your project, and decide on a business model that works with the open source approach.

Sirius Web, simplify graphical editing of data on the web

Editing structured data graphically allows to better understand aspects such as relationships between specific data, interlocking on several levels, but also to more easily identify certain characteristics thanks to visual information (size, colour, shape, icons, …). But to provide this kind of user experience, developing domain-specific web graphical editors (DSL) remains a complex task. Sirius Web is a new open-source project in the Eclipse foundation, based on full web, which simplifies the definition of domain concepts, the creation of graphical editors, and the deployment to users. All this is done from a simple web browser. Modular, Sirius Web can also provide editors that can be integrated into existing web applications to add a graphical dimension. During this talk, we will briefly review the origins of the project, the different use cases, as well as the architecture and technical choices, to leave room for demonstrations of the main features.

Cloud: some lessons learned from my (our) failures

Caution this session is a real-life feedback, some of these could hurt sensible audience… I have been practicing OSS and Cloud for years and along the way I have been through some mistakes. I started on 2012 with OpenStack and its ecosystem, then Kubernetes’ one in 2016 and now I’m going through on Multi-cloud Kubernetes (AWS, AKS, OpenShit), GitOps, and migration to K8s projects. Technical and management complexity have increased exponentially since major companies have been started to implement at scale OSS. From these projects, on some we succeeded and others we failed, I have learnt a lot and I would like to share during this sessions some of take-away lessons: A Cloud Platform = 1 Product = 1 Dedicated Team ; Be smart and stay modest: Cloud Technologies are complex ; Avoiding the “we will see what happens” attitude ; Build on On-boarding approach and a clear operating model.

Can Linux serve Functional Safety as well as Cyber Secured domains

Linux in the past years has demonstrated its capability to serve highly secured applications. Will it be also capable to cover Functional Security demand ? Are we soon going to see ASIL B or D Linux based on the market ? While the basic tools required to serve Cyber Secured and Functional Secured applications are similar and even often identical, the process currently used for Functional Safety certification remains a serious challenge and still bars access to Functional Security to most Open Source applications. As we are now seeing the first systems claiming compliance with the CEI 61508 or ISO 26262 (automotive), we will look how those early players are configuring their systems to achieve compliance with Open Source based OS and try to demonstrate that the future will most likely follow that new trend.
