WAM is the web runtime used in LG webOS (both for its products and the Open Source Edition), and has been adopted by Automotive Grade Linux. It is built on top of Chromium web engine and its Ozone Wayland backend. In this presentation I will showcase its main features, and talk about its history, from HP/Palm devices, through LG TV and its Raspberry PI Open Source Edition, to end with its adoption in AGL. WAM, also known as WebAppManager, or Web Application Manager, is a system service providing web runtime capabilities in LG webOS and AGL platforms. Its goals are: * Performance through reuse of resources among web applications. * Provide a native-like experience to applications based on the Web Platform standards. It has been a central part of LG webOS in all its flavours, including LG webOS Open Source Edition. As such, it provides a great example of how to integrate the web experience in a Linux system, providing graphics integration through Wayland protocol. It will be a history of web engines. From QtWebKit, to QtWebEngine, to a custom embedding API directly on top of Chromium. This is also going to be a history of the flexibility of the platform, as it was possible to integrate it not only on webOS, but also in the different releases of Automotive Grade Linux, even after different architecture rewrites. This presentation will highlight the strong points that make WAM specially flexible for integrating in different Linux platforms. A retrospective of the main milestones of WAM in last decade. But also a look into its future. (c) FOSDEM 2023 4 & 5 February 2023 https://fosdem.org/2023/schedule/event/wam_runtime/

At some point, the code you write today will be deleted and replaced with something new. This talk will discuss the life cycle of a large code base, and how to manage it over time to accommodate rewrites, giving examples from a major rewrite of the Firefox build and release pipeline over the last two years. You'll learn how to replace components of a running distributed system while keeping it operational, the proverbial replacing the wing of an airplane in flight.

The complexity of agricultural droughts requires a consistent, reliable, and systematic method for monitoring and reporting. Amongst the various indices used to monitor this phenomenon, the soil moisture anomaly has been proven to be a more reliable predictor. However, the datasets required for computing this index are often large and computationally demanding. To address this challenge, we have developed SMODEX, a Python package that enables scalable, fast, and open-source standard-compliant computation and visualization of soil moisture anomalies. SMODEX simplifies the computation and visualization of time-series for soil moisture and soil moisture anomalies from high-dimensional climate datasets. It allows for quick and easy parallelization of the computation on a daily, weekly, and monthly timescale. Additionally, SMODEX implements a straightforward workflow for automating the use of FAIR (Findable, Accessible, Interoperable, and Reusable) principles in producing and sharing outputs by leveraging the open source STAC API. The package is extendible and provides information on how to contribute to the project, test suites, test coverage, and a use case for the South Tyrol region, all provided in the package repository. In the future, additional agricultural drought indices and indicators would be included to serve to even larger community of researchers, policy makers, and individual users.

Tracking aeroplanes in real time with Open Source Software is possible. Aircrafts must continuously send their current flight parameters to air traffic controllers on the ground and to other aircrafts. This generates a lot of data, especially when planes are being tracked by multiple sensors. The Open Data Hub on the other hand offers a great backbone for data storing and processing, where the correct datasets have to be identified and filtered. After all transformation on the data is done, it will be exposed via API to be further used by a web application. Bringing together sensor generated data, the Open Data Hub and custom web applications, is a showcase on how the Open Data Hub can be used as a service: OaaS.

The transition from Web 2.0 to Web 3.0 has fueled the need for a secure and decentralized cloud storage solution for digital assets. Web 2.0 was characterized by centralized platforms where user data was under the control of companies. In contrast, Web 3.0 aims to empower individuals and foster a decentralized web that supports and benefits the Free Software and Open Data Communities. Blockchain technologies facilitate seamless collaboration and interoperability among diverse stakeholders in the Free Software and Open Data communities. Developers can establish open and transparent ecosystems where data can be shared, verified, and integrated across multiple platforms. Beez, with its own blockchain infrastructure, offers a secure and transparent platform for digital asset exchanges, bolstering transaction integrity and trust. By distributing data across a network of nodes, Beez ensures security and mitigates the risk of single points of failure. Users retain control over their data, safeguard their privacy, and can take advantage of the incentive mechanisms offered by blockchain networks. During our presentation, we will explore the role of AI within Beez's ecosystem, facilitating accelerated data processing, correlation, and intelligent automation. AI unlocks valuable insights from blockchain data, and we will touch upon the use of Inductive Logic Programming (ILP) to enhance programming performance. The integration of Blockchain and AI technologies holds great potential for advancing the safety and efficiency of the Open Data ecosystem. By combining decentralized data storage, trust-building mechanisms, and intelligent data processing, Beez is paving the way for a more secure, transparent, and user-centric digital landscape.

We are becoming more and more dependent on the Internet for our work, education, communication, personal relations and entertainment. Our digital devices conquered an unprecedented level of importance in our life. However, we are facing a loss of control over our smartphones, tablets and other devices for internet connection. It's time to resolve monopolies and re-establish democratic control over the technology we most depend upon. This talk will present the challenges end-users are facing to get more control over their devices and how Free Software is key for a consumer re-empowerement. The talk will present real-life examples of policy demands against gatekeepers on digital markets, such as the struggle for Router Freedom in the last years and how Device Neutrality can serve as an important instrument for pushing forward end-user-oriented digital policies.

MOSH and MOAH are the abbreviation of two groups of chemical compounds found in mineral oils. “MOSH” stands for Mineral Oil Saturated Hydrocarbons. MOAH stands for Mineral Oil Aromatic Hydrocarbons. Both of them are under European deeply evaluation because there are two food contaminants. According to the current state of scientific knowledge, there is no sufficient toxicological evidence to prove a health risk to humans from saturated mineral oil fractions (MOSH). Meanwhile, MOAH are suspected to be carcinogenic (especially PAH-like compounds with 3-7 ring systems), therefore their levels in food should be reduced according to the ALARA-principle (as low as reasonably achievable).

Up-to date measurements of surface meteorological variables are essential to monitor weather conditions, their spatio-temporal variability and the potential effects on a wide range of sectors and applications. Moreover, when included in continuous records of long historical observations spanning several decades, they become essential for assessing long-term climate variability and change locally and on a regional level. Automated pipelines capable of retrieving and processing near-real time meteorological data satisfy the primary prerequisites towards the development and advancement of effective and operational climate services. With a public and operational near real-time monitoring web platform in mind, we present automated pipelines to collect and process up-to-date daily temperature and precipitation records for Trentino South Tyrol (Italy) and surrounding areas, and to derive their spatially interpolated fields at sub-km scale. Our pipelines are composed by multiple steps including data download, sanity checks, reconstruction of missing daily records, integration into the historical archive, spatial interpolation and publication onto online FAIR catalogues as (openEO) “datacubes”. The different APIs, data formats and structure across the various data sources, and the need to merge the data onto harmonized meteorological layers, make this a typical case of the so-called Extract, Transform and Load (ETL) pipelines, and, in order to follow the principles of data reproducibility and Open Science, we embraced open-source automated workflow management through GitLab’s Continuous Integration / Continuous Development (CI/CD) capabilities. CI/CD workflows greatly help the management of the relatively complex graphs of tasks required for our climate application, ensuring seamless orchestration with thorough flow monitoring, application logs, transactions rollbacks, and exception handling in general. Native pipeline-oriented software development also fosters a clean separation of roles among the tasks, and a more modular architecture. This effectively reduces barriers to collaborative development and paves the way for robust operational climate services for researchers and decision makers in the face of the changing climate.

The Open Science movement aims to increase the transparency, reproducibility and inclusiveness of academic research. One of its central goals is therefore to make research outputs broadly available, e.g., manuscripts (Open Access) or research data (Open Data). While software/code created in the course of scientific research is a key artifact of scientific research that is clear distinct from the latter two, it has until recently not received the same attention as manuscripts or data, although it follows its own set of paradigms. In this talk I will present an overview on how the core concepts of Free Software and the FAIR (findable, accessible, interoperable, reuseable) Principles intersect, what this means for managing code as research output and recent initiatives on the European level that will provide support for these issues.

Software freedom can be defined in many ways but in legal terms it is squarely defined by a set of approved FSF and OSI software licenses. Yet everyone realizes that beyond these licenses the goal of software freedom and digital sovereignty cannot be achieved without the ability to master and create hardware components and systems - and beyond that, to rely on open digital infrastructure (servers, datacenters, and resources) . This talk will present the challenges around these topics and what we, collectively in Europe already do and can do to ensure our independence and our freedoms.

EDP-portal is the access point to the Environmental Data Platform of Eurac Research since 2021 to achieve FAIRness of our datasets. It allows to publish data and metadata and provides APIs and web services for data access. In the last 2 years the EDP improved the findability and accessibility of the data collected throughout the curation of metadata that was improved with the DOI registration for datasets. The result is a higher metadata quality where the final user can easily find how to properly cite datasets with a persistent identifier. The portal itself and main data repositories are registered in FAIR-sharing portal with their own DOI. The SW components of the EDP are totally based on open source projects.

As open source software becomes the foundation to build digital products, to run the backbones of ICT infrastructure and to ensure digital sovereignty and cyber resilience, both the technology as well as the communities that develop it inevitably move into the focus of regulators. The European Union is advancing a number of policy initiatives that regulate liability, cyber security, data handling and AI applications in digital products, among others. This is a challenge for the still quite decentralised and globally operating open source community. How could the open source community participate in legislative processes, and what may be the potential impacts of the upcoming regulation on the open source development process and community dynamics?

How to sharpen the demand for public code across Europe and monitor progress with TEDective For six years, the Free Software Foundation Europe has been calling with a broad alliance for publicly funded software to be published as Free Software. This initiative has become a great success: Our demand "Public Money? Public Code!" has found its way into government strategy papers, party programs, as well as coalition treaties, and is being discussed in public administrations across Europe. At the same time, we see less progress than expected and vendor lock ins remain a crucial issue. Digital sovereignty is redefined bypassing Free Software. There is openwashing in publicly funded companies, and government projects in favour of Free Software remain empty words. Public statistics on the procurement of Free Software are largely unavailable. It is therefore no longer enough to promote the idea of "Public Money? Public Code!". We as the Free Software community should be even more vigilant than before – continuing to praise small steps in the right direction, but pointing out and criticising omissions and lack of implementation. We should become more like watchdogs. In the talk we will look at some examples of lack of implementation of Free Software policies. We will discuss how we, as civil society, can identify such shortcomings and how to deal with them. We will present our initiative TEDective – a free-software solution that makes European public procurement data explorable for non-experts, aiming to provide you with a powerful tool to keep an eye on real progress towards "Public Money? Public Code!" across Europe.

The Internet today forms the backbone of the digitisation of our society and economy. As connectivity increases, the boundaries between the real and digital world get increasingly blurred. However, there has been an erosion of trust in the Internet following revelations about the exploitation of personal data, large-scale cybersecurity and data breaches, and growing awareness of the proliferation and impacts of online disinformation. What can be done to improve the Internet as a platform for future generations? What initiatives are currently in place to build key technological blocks of an Internet that supports human-centric values, such as privacy, security, and inclusion, while reflecting the values and norms all citizens should enjoy in Europe? This talk will explore why the current state of the internet must be re-imagined and re-engineered in order to support healthy societies, the existing European Commission initiative to work towards doing so, and the role of Free Software in accomplishing these goals.

2023 saw the launch, after a long and well-structured revision and development process, all based on a fruitful collaboration between several departments of the Autonomous Province of Bolzano, most of the township in South Tyrol, Informatica Alto Adige (SIAG - Technical partner) and the Consortium of Municipalities of the Province of Bolzano, of the new version of the integrated geographic data management system IGis Maps. In use for years in South Tyrol, has in the Consortium one of its most enthusiastic contributors and supporters. The very first version was released about eight years ago and its implementation was based on the idea of creating a multi-purpose GIS management system that could support different types of users, that was highly customizable, and, above all, that could be widely shared among the various management entities, both public and private, present within our territory. After years of use and ad-hoc developments, we can finally present the new version of the IGis Maps system, which incorporates all the technical and technological improvements we realized the system needed. It was not just a major update together with new functionalities combined inside the previous software structure, but a true re-engineering that led, among other things, to a new and more efficient user interface, a major advancement regarding the internal security, an optimization and improvement of the entire editing section as well as an optimization of the section regarding the automatic geo-processes. A mobile version is currently under development to better support any field activities, for which a very powerful option will be included, the possibility of creating special work sessions in off-line mode so as to be able to operate even in areas without a proper cellular line network coverage. Other very important peculiarities concern that the system is developed using a totally free software code and infrastructure, that a detailed documentation has been produced to ensure sustainability to any further future evolution, even in case of technical partner turnover, and finally, that by taking advantage of the high standards and levels of security access can be guaranteed to any type of user. From professional users, through dedicated access and qualifications or, using the ordinary SPID, to the private citizen. We will show examples of how different types of users and stakeholders now permanently use the system for the management of a variety of tasks related to their activities, and how it was possible to customize IGis Maps to create visualization and data management contexts that best meet their needs. We will also present a related project concerning the updating and the correction of the new technical basal cartography, built upon the new Basic Core specification, achieved through the automatic conversion implemented by the SIAG team starting from the previous National Core cartography. With the new IGis Maps it was possible to create an a
