They help finding bugs sometimes missed in simulation, triggered by corner cases you didn't think to check. This talk will give a little background on how they work, the available ecosystem of tools, show some small examples on how to use them, and some practical results from real-life usage.

However, our architecture is highly distributed, and our approach to many things such as content hosting is significantly different to that of other platforms. We don't need accounts, servers can be anywhere, and content can be hosted on any HTTP server. Overte closely imitates the WWW, and this brings plenty benefits, but also creates problems other platforms don't have.

In this talk, I will explain what makes us different, what the benefits are to doing things our way, how do we solve problems other systems don't have, and why you might want to try Overte for its unique approach.

These devices allow the control of electricity flows such as battery charging, motor control and renewable energy usage. This critical technology is mostly proprietary blocking innovation and knowledge transfer.
The OwnTech project has the objective of creating an open-source technology suite similar to Raspberry Pi or Arduino for energy management. Our goal is to provide our community with the tools to act and re-imagine their energy system from the bottom up.
In this talk we will introduce the OwnTech project, its mission and show a study case of a 1kW 24V micro-grid developed by Alyssia Dong, an assistant professor at the University of Angers, for educational purposes.

While the study of scientific instruments has been extensively covered in science and technology studies (STS), as well as aspects related to digital data, software strangely remains absent. I will build on the success of Jupyter computational notebooks to sketch a social study of open source scientific softwares.

The Jupyter project, initiated in 2001 by a physics graduate student interested in scientific programming, has gradually evolved into a global data science infrastructure. I will demonstrate the importance of closely examining its trajectory by identifying the continually negotiated conditions for the transition from local usage to a role as a generic instrument, progressively leading to its integration into a diversity of services beyond scientific communities. The dissemination of computational notebooks has thus not only facilitated a convergence between open code and open science but also between the practices of researchers and those of computer developers, leading to the stabilization of a specific infrastructure for data analysis.

Linux is slightly falling behind. In this talk, I will cover how IPv6-only and IPv6-mostly networks work and what needs to be done to have first class support in Linux.
Let's talk about IPv6-mostly networks - the kind of networks which run IPv6-only for devices supporting it while providing some IPv4 for devices dependent on it. This can be done by DHCPv4 option called IPv6-only Preferred. Using this option, a device can opt-out from IPv4 if it does not need it for proper functionality.

But even if a device opts out from IPv4, chances are it would need some IPv4-as-a-service for supporting legacy applications. Typically, 464XLAT concept is used. This relies on a client-side translator (CLAT) responsible for converting residual IPv4 into IPv6. If such a translator is missing, which is the case for the most Linux desktop distributions nowadays, most things would work normally, but chances are you will hit some corner case where your computer complains about no connectivity.
There are solutions to set up CLAT on Linux but none of them is mature enough. Let's talk about what needs to be done to change this.

The ability to checkpoint containers opens up many new use cases. Containers can be migrated without loosing the state of the container, fast startup from existing checkpoints, using spot instances more effective. The primary use case, based on the title of the Kubernetes enhancement proposal, is the forensic analysis of the checkpointed containers.

In this session I want to introduce the different possible use cases of "Forensic Container Checkpointing" with a focus on how to perform forensic analysis on the checkpointed containers. The presented use cases and especially the forensic analysis will be done as a live demo giving the audience a hands on experience.

Bootloaders are one of the biggest pain points when it comes to booting upstream
Linux on Qualcomm devices, they require that distros support 5 versions of the Android
boot image header, weird non-standard devicetree properties, and are
generally a huge headache. As modifying the bootloader is out of the question,
we can at least replace the environment it gives us with a more sensible one...

In this talk, I'll give a brief introduction to what an EFI bootloader actually is,
how they work, and how U-Boot fits into the picture as a second-stage
bootloader. I'll cover the work I've been doing to improve Qualcomm support in
upstream U-Boot, and how we can drastically lower the barrier of entry for
distro support on Qualcomm phones.

Lastly, I'll go over the new process for porting a Qualcomm SoC to U-Boot, and
demo booting Linux with EFI runtime support on a Qualcomm phone.

I'll also give a sneak peak at what would be possible if we had greater ownership of our devices.

Why you should care
This talk is primarily aimed at the upstream community, if you work on upstream support for any Qualcomm devices - be it phone, tablet, Chromebook, or vehicle - then you can likely benefit from running U-Boot.

UEFI is now the lowest common denominator, and supporting it makes Qualcomm devices a viable target for more mainstream distros.

Initially developed more than 20 years go, to meet the unique demands of the world's largest physics lab, Indico has since evolved and transcended its origins, becoming a globally adopted solution for the organization events of all scales, used in more than 300 organizations world wide, including the United Nations, and integrated in a lively user community. We will be focusing on the main features of the tool, its role at CERN and elsewhere, the work we have been doing regarding community building, as well as plans and ideas for the future.

This is one of the primary benefits of open communities: the assimilation of progress from a wide and diverse pool of talent. However, care must be taken to ensure that the process of acceptance is free from social friction, lest arguments bring down and delay development of the project. This lightning talk covers the social issues open community maintainers and external contributors face during the submission of a patch or other change, why conflicts arise between parties, and how to handle difficult public disagreements to bring threads of discussions back on topic to focus on the benefit of the project and community. Synergy is when multiple parties come together to produce something greater than the sum of their parts, and it's what we will strive for in this talk.

Now, four years after NetBSD 9, NetBSD 10 brings a huge number of changes and improvements. This talk will dive into the most important new features of NetBSD 10, such as performance and security improvements, expanded CPU and GPU support, improved virtualization and more!

Another strength of NetBSD is its package system, pkgsrc, which is portable to dozens of other OSes and can even be used like virtualenv for development and deployment environments.

But over all this, the question remains: how relevant is NetBSD these days? There is a small but friendly, and tight-knit community of users and developers. The focus on portability and cleanliness provides a good system for both beginners and tinkerers, but also a rock-solid server or workstation system. We will go over some cool use cases and show ways that you can get involved.

However, moving them into a production environment often leads to a complex set of challenges. 
Challenges related to production readiness, version control, testing, reproducibility, and modularity are common.  
 
In this talk, we will delve into the specifics of these challenges and demonstrate how our tool, Versatile Data Kit (VDK), effectively addresses them. From deploying production-relevant code to ensuring linear execution for reproducibility, we will provide insights into practical solutions that could enhance efficiency in your data analytics and machine learning workflows. This session is aimed at those looking to understand the complexities of productionizing notebooks and explore potential methods to overcome these challenges.
Benefits to the Ecosystem - solutions to several specific pain points of Productionizing Jupyter notebooks.
For this talk, some prior knowledge of Jupyter Notebooks is necessary.
