One Boot Config to Rule Them All: Bringing UAPI Boot Specification to Legacy BIOS (asg2025) 24:59

לפני 7 ימים24:59

24:59

The UAPI Boot Loader Specification defines conventions that let multiple operating systems and bootloaders share boot config files. So far, only systemd-boot implements it - and it’s UEFI-only by design. As a result, hybrid UEFI/BIOS images require maintaining (and keeping in sync) two sets of bootloader configs: one for systemd-boot, and one for a legacy bootloader such as syslinux. I set out to fix that by building a BIOS bootloader that uses the UAPI Boot Loader Specification - allowing both UEFI and legacy boot to use a single shared set of config files. This talk is about why that matters, how I built it, and what comes next. In this talk, I’ll cover: - What the UAPI boot spec is - Why you'd want to use legacy boot instead of EFI/systemd-boot - *spoiler: you don't! but you might have to* - How I implemented UAPI boot support for legacy BIOS - What about UKIs? - A live demo of the bootloader in action - The current state of the project and what’s next https://uapi-group.org/specifications/specs/boot_loader_specification https://github.com/nkraetzschmar/bootloader Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://cfp.all-systems-go.io/all-systems-go-2025/talk/ANC879/…

What's up with test.thing (asg2025) 25:20

25:20

`test.thing` is a VM runner which targets guests using an API defined by systemd. It started after a conversation at devconf about turning `mkosi qemu` into a library. A quick intro. ~~composefs is an approach to image-mode systems without the disk images. Files are stored in a de-duplicated content-addressed storage with integrity guaranteed through fs-verity. The last year has seen an acceleration of development on composefs-rs, a pure Rust implementation of the ideas behind composefs. Our goal is unification of the storage of bootable system images (via bootc), application Flatpaks, and traditional OCI container environments, bringing deduplication and integrity guarantees to all three. An overview.~~ Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://cfp.all-systems-go.io/all-systems-go-2025/talk/MLTTHW/…

Yocto's hidden gem: OTA and seamless updates with systemd-sysupdate (asg2025) 26:33

לפני 7 ימים26:33

26:33

Updates are a critical piece of managing your fleet of devices. Nowadays, Yocto-based distributions can utilize layers for well-established update mechanisms. But, did you know that recent releases of Yocto already come with a simple update mechanism? Enter systemd-sysupdate: a mechanism capable of automatically discovering, downloading, and installing A/B-style updates. By combining it with tools like systemd-boot, we can turn it into a comprehensive alternative for common scenarios. In this talk, we will briefly introduce systemd-sysupdate, show how it can be integrated with your Yocto distribution, and share thoughts on how it can be improved further.

UKI, composefs and remote attestation for Bootable Containers (asg2025) 42:50

לפני 7 ימים42:50

42:50

With Bootable Containers (bootc), we can place the operating system files inside a standard OCI container. This lets users modify the content of the operating system using familiar container tools and the Containerfile pattern. They can then share those container images using container registries and sign them using cosign. Using composefs and fs-verity, we can link a UKI to a complete read only filesystem tree, guaranteeing that every system file is verified on load. We integrate this in bootc by creating a reliable way to turn container images into composefs filesystem trees, and then including the UKI in the container image. We will share the progress on the integration of UKI and composefs in bootc and how we are going to enable remote attestation for those systems using trustee, notably for Confidential Computing use cases. https://github.com/containers/composefs-rs https://github.com/bootc-dev/bootc https://github.com/confidential-containers/trustee Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://cfp.all-systems-go.io/all-systems-go-2025/talk/TNKPQS/…

A terminal for operating clouds: administering S3NS with image-based NixOS (asg2025) 34:54

לפני 7 ימים34:54

34:54

S3NS is a trusted cloud operator that self-hosts Google Cloud infrastructure in France, targeting the SecNumCloud certification, the most stringent Cloud certification framework. SecNumCloud includes strict legal and operational constraints. To manage these systems securely and reproducibly, we’ve built a family of dedicated administration terminals based on the image based philosophy. These terminals rely on NixOS semantics and draw from the ParticleOS ecosystem: systemd-repart, and dm-verity, ensuring atomic updates, full immutability of the Nix store, and verifiable integrity of the boot chain and runtime system (measured boot), while using remote attestations by TPM2 when connecting to production assets. We will present the purpose of these terminals and what needs they serve along with their high level characteristics: partition layouts, provisioning and connection flow to the production assets. This talk will show an application of many of the concepts that were presented in the NixOS ecosystem and in All Systems Go itself by the systemd community.

Introducing ue-rs, minimal and secure rewrite of update engine in Flatcar (asg2025) 24:20

לפני 8 ימים24:20

24:20

Introduce ue-rs, a fresh project that aims to be a drop-in reimplementation of update engine, written in Rust. The goal of ue-rs is to have a minimal, secure and robust implementation of update engine, required by A/B update mechanism of Flatcar Container Linux. Just like the existing update engine, it downloads OS update payloads from a Nebraska server, parses its Omaha protocol, verifies signatures, etc. This project, however, is different from the original update engine in the following aspects. First, it aims to be minimal, by reducing heavyweight legacies in the update engine. Moreover, written in Rust, it brings a huge advantage for security, especially memory safety, in contrast to the original update engine, which is written mainly in C++ and bash. Finally, in addition to traditional OS update payloads, it supports systemd-sysext OEM, which is supported by Flatcar.

Dirlock: a new tool to manage encrypted filesystems (asg2025) 26:27

לפני 8 ימים26:27

26:27

In the Linux world there are several tools and technologies to encrypt data on a hard drive, most falling into one of two categories: block device encryption (like LUKS) or stacked filesystem encryption (like EncFs or gocryptfs). This presentation will introduce Dirlock, a new tool that belongs to a third category: native filesystem encryption, using the kernel's fscrypt API. Dirlock is currently being developed and its aim is to provide a flexible way to encrypt files, suitable for both user accounts and arbitrary directories, with full PAM integration, support for hardware-backed mechanisms such as FIDO2 or TPM and with a D-Bus API for easy management.

container-snap: Atomic Updates from OCI Images using Podman’s Btrfs Driver (asg2025) 22:46

לפני 8 ימים22:46

22:46

Traditional package updates using tools like RPM or Zypper can introduce risks, such as incomplete updates or accidentally breaking the running system. To overcome these challenges, we developed **container-snap**, a prototype plugin designed to deliver atomic OS updates—updates that are fully applied or rolled back without compromising the system's state. container-snap leverages OCI images as the source for updates and integrates seamlessly with openSUSE’s [tukit](https://github.com/openSUSE/transactional-update) to enable transactional OS updates. By utilizing Podman’s btrfs storage driver, it creates btrfs subvolumes directly from OCI images, allowing systems to boot from the OCI image. This approach empowers users to construct their own OS images using familiar container image-building tools, like Docker or [Buildah](https://buildah.io/). In this session, we’ll dive into: - The architecture and technical implementation of container-snap - Challenges encountered during development and how we resolved them - Key lessons learned along the way - A live demo showcasing container-snap in action Come and join this session to learn more about how to boot from an OCI image without bricking your system!

Forget zbus, zlink is the future of IPC in Rust (asg2025) 38:14

לפני 8 ימים38:14

38:14

Last year, Lennart Poettering of the systemd fame, [gave a presentation](https://media.ccc.de/v/all-systems-go-2024-276-varlink-now-) at this very same conference, where he introduced Varlink, a modern yet simple IPC mechanism. He presented a case for Varlink, rather than [D-Bus](https://en.wikipedia.org/wiki/D-Bus) to be the future of Inter-process communication on Linux. As someone who works on D-Bus, I took upon myself to prove him wrong, only to find out that I achieved exactly the opposite. It didn't take long before I got convinced of his vision. Since I was largely responsible for giving the world [an easy to use D-Bus Rust library](https://crates.io/crates/zbus), I thought it's only fitting that I do the same for Varlink. This talk will be the story of the creation of such a library, the challenges I faced, where Varlink fits the Rust idioms really well and where it does not and how all of this affected the development and the API.

Privilege delegation for rootless containers, what choices do we have? (asg2025) 21:43

לפני 8 ימים21:43

21:43

Going for minimal containers with restricted system calls and unprivileged users is the usual Kubernetes approach these days, and it works great for most web apps. However, the development of more complex infrastructure extensions frequently hinders application functionality. While looking for a solution to deploy virtiofsd in an unprivileged container for KubeVirt, we stumbled on seccomp notifiers. Seccomp notifiers are a kernel feature which monitors syscalls and get notifications to a userspace application when a syscall is executed. Alternative options involved either the use of a custom protocol using UNIX sockets or the deployment of virtiofs as a privileged component alongside the unprivileged VM. After our evaluation, the seccomp notifier turned out to be the simplest solution among all the choices. Unfortunately, the main constraint is the monitor's resilience after a restart, such as after a crash or an upgrade. This limitation forced us to back up to one of the less elegant approaches. But there is hope how this could be solved! The session will explain why seccomp notifiers are a lean solution to avoid extra userspace communication and synchronization, the current limitations and possible future solutions to overcome today’s challenges. Our experience will teach audiences several methods for dividing their privileged infrastructure. Utilizing virtiofsd as an actual example and a target application for KubeVirt integration and deployment. We will discuss the difficulties of using rootless containers in this session, as well as the design patterns, technologies, and tactics we thought about and ultimately chose to maintain or reject.

CentOS Proposed Updates: Bridging the Gap between development and production (asg2025) 25:32

לפני 8 ימים25:32

25:32

CentOS Stream is especially suited for production deployments. In these environments it's often common to develop improvements to distribution packages and want to contribute them upstream. Unfortunately, until very recently that required one to then maintain their own build and deployment pipeline for the packages, at least until the changes made their way into the distribution. CentOS Proposed Updates (CPU) SIG aims to bridge this gap - changes that have been submitted as merge requests can be built in this SIG, providing those who run Stream in production with access to needed updates while they make their way into CentOS Stream. We hope this will help increase collaboration between RHEL engineers, CentOS Stream contributors, and the rebuild community as well, especially those that have distributions derived from CentOS Stream directly (such as AlmaLinux with AlmaLinux OS Kitten), as everyone can focus on making improvements without reinventing their own build pipelines.

Extending Fedora Atomic Desktops using systemd system extensions (asg2025) 25:54

לפני 9 ימים25:54

25:54

On image based desktops distributions such as Fedora Atomic desktops and Universal Blue, users are expected to run their graphical applications using Flatpaks and their command line ones using containers. But that approach does not work well for some applications that require more privileges, direct access to devices or kernel interfaces. With systemd system extensions (sysexts), it is possible to extend an image based system on demand. Sysexts come with a lot of advantages: they can be created out of arbitrary content (not only packages), are quickly enabled or disabled and can be built and shared independently of the main distribution channels. We will demonstrate how the Atomic Desktops can take benefit of sysexts to provide extensions such as virtual machine management (libvirt), alternative container runtimes (moby-engine or docker), IDE (VS Code) or debugging (gdb). We will also look at important details when building sysexts, the current limits when deploying them (SELinux policy modules, service management, RPM database update), what is currently blocking us from using it for more complex cases (kernel modules) and what we would need to properly manage and update them.

Look ma, no secrets! - bootstrapping cryptographic trust in my homelab using Nix, UKIs, TPMs and SPIFFE (asg2025) 27:35

לפני 9 ימים27:35

27:35

All the big cloud providers provide your machines with a unique cryptographic identity that can be used to talk to their cloud services securely without having to manage or rotate any cryptographic secrets yourself. For example GCP has Service accounts and AWS has IAM roles. This ubiquity of cloud identity and the seamless integration with all the the services of these cloud providers is one of the reasons why they are so successful. SPIFFE (Secure Production Identity Framework For Everyone) tries to unify these concepts of workload identity in a vendor neutral framework. But how do we bootstrap our cryptographic identity securely when we are running things on our own hardware as opposed to on cloud? What is our bottom turtle? In this talk, I will show how I use Nix in combination with the swiss-army knife of tools provided by systemd (ukify, systemd-measure, systemd-repart, systemd-veritysetup-generator) to create reproducible images for which we can predict TPM measurements. Paired with a custom attestation plugin for SPIRE (the reference CA server for SPIFFE) that uses TPM remote attestation I can give each of my servers a unique identity encoded in a TLS certificate if and only if they were booted up with the software that I intended them to boot up with. This then allows me to have workloads talk to each other with mutual TLS without having to manage any keys or certificates myself.

systemd-confext Two Years On: Versioned Overlays for /etc, Reloaded (asg2025) 25:45

לפני 9 ימים25:45

25:45

systemd-confext is a lightweight overlay mechanism for /etc, allowing you to drop in a configuration extension ("confext") bundle and let systemd make it visible to your service as though it was already shipped with the base image. Building on the same extension magic as systemd-sysext, confext also introduces extra features tailored for the /etc use case, such as vpick-ing the newest version and the ability to pick up config revisions with a `systemctl reload`. This talk presents the changes to systemd-confext since [its debut at All Systems Go! 2023](https://cfp.all-systems-go.io/all-systems-go-2023/talk/XLQNDJ/), the lessons learned along the way to make it work, and how we leverage this capability at Microsoft already to deliver configuration payloads in production. Immutable Linux distributions offer stability and reproducibility, but at the cost of configuration changes needing time to build. A small configuration or system change can then require complete redeployment of the entire OS, adding friction to development work and impacting customers. This is not acceptable for certain Linux environments at Microsoft, where only seconds of planned downtime budget exist every year. systemd-confext is intended to be a signed, `dm-verity`-protected, live configuration update mechanism meant to address this issue. It provides a way to make quick additions in a secure and reliable way with minimum customer impact. Two years later, confext now supports host-level payloads to /etc and also works in the individual namespaces of services and portable units via `ExtensionImages=` and `ExtensionDirectories=` too. One of the recent significant additions is that systemd-confext has been integrated with `systemctl reload`, giving it the ability to pick up new configuration revisions during a reload, not just a restart. Combined with services that implement notify-reload, it is possible to simply drop a new versioned extension into the watched directory to trigger the reload flow and update the service config. We'll review how these features can be used and include a demo of a couple of use cases, including path-activated units to deploy config payloads in production at Microsoft. We'll also briefly discuss the namespace and mounting changes needed in the systemd codebase to make this integration work.

Accessing shadow records via varlink (asg2025) 26:12

לפני 9 ימים26:12

26:12

Provide a varlink service to access /etc/passwd and /etc/shadow so that no setuid and setgid binaries are necessary for this task. There are two independent "problems" which can be solved with the same idea: all files in /usr should be owned by root:root and no setuid binary should be needed. The first one is a requirement of image based updates of /usr to avoid UID/GID drift, the second one is a security feature wished by systemd developers and security teams. Currently most setuid binaries (or setgid binaries owned by group shadow) beside su and sudo only need this to read the shadow entry of the calling user. This task could be delegated to a systemd socket activated service which provides the user shadow entry for the calling user. In this talk I will present the why, the current implementation and feedback from security teams.

How I optimized away 94% CPU from zbus (asg2025) 24:03

לפני 9 ימים24:03

Haven’t you ever wanted to find ways to make your Rust code the most optimal in the world? I know how you feel. This is a talk, where I’d tell you how easy it is to profile your Rust software and how most often the solutions are trivial. This is a story of how I used a few readily-available Open Source tools to achieve huge optimizations in [zbus](https://crates.io/crates/zbus), a pure Rust D-Bus library. This was long journey but gains were worth the efforts. I will go through each single bottleneck found, how it was found and why it was a bottleneck and how it was optimized away. While attending this talk will by no means make you an expert in optimizations, it is my hope that by you will be able to relate to some of bottlenecks or solutions I will present (“hey”, I also do that in my code!”) and learn from my experience. Maybe afterwards, you can suggest an even better solution? Moreover, if you don’t already have any experience with profiling and optimizations, this talk should be a good introduction for that.

Linux IPC: Lost between Threading and Networking (asg2025) 25:57

לפני 9 ימים25:57

25:57

Communication is paramount in modern application development. This applies equally well to the process of writing applications and to the code itself. The complexity of the tasks ahead of us calls for a distributed and coordinated development effort, and this often manifests in our code: We design distributed, communicating systems to split complexity and responsibility among many people and teams, and at the same time meet the demand for ever faster systems. The last decade showed significantly increased popularity in API design, network protocols, and distributed computations. At the same time some of the most intriguing language research improves how multi-threaded applications synchronize and exchange information without sacrificing safety or performance. Between these two lies an almost forgotten world: Linux Inter-process communication (IPC) has lost ground to thread-communication and networking protocols. Let us look at how other operating systems have evolved their IPC layers, what new systems decide to go with, and why Linux IPC has not seen any major changes since the 90s. And finally, can we lift Linux IPC out of stagnation and catch up with everyone else?

BPF Tokens in systemd (asg2025) 23:50

לפני 9 ימים23:50

23:50

Running **BPF** programs today requires *CAP_BPF* capability, which is an all or nothing BPF capability. But BPF nowadays spans a large area, from simple monitoring to potentially invasive fields like network or tracing. BPF Tokens aims to add fine grained BPF capabilities to systemd units and containers, avoiding to give the whole *CAP_BPF* capability or even worse running the service as privileged user.

Systing: tracing for the lazy (asg2025) 29:24

לפני 9 ימים29:24

29:24

Systing helps you solve problems in minutes rather than days. Out of the box it gives you everything you could possibly need, combined with perfetto’s visualization you will never be confused again. This talk will introduce systing, a tracer that is built on modern BPF tooling, purpose built to debug large applications with complicated interactions. This will be little talk and mostly demo. Two decades of experience debugging kernel problems has been poured into this tool to make it as straightforward as possible. I will walk through the basic usage, and show a case study investigation to give a feel for the various features that set it apart from the lower level tools we all use and love.

Why you should contribute to systemd! (asg2025) 23:28

לפני 9 ימים23:28

23:28

I'll use these 20 minutes to explain why and why contributing to systemd is a great experience. We'll avoid beating dead horses by not discussing git forges and email, but instead focus on the development experience, from building systemd distribution packages from git main, running integration tests against those distribution packages, debugging failures, writing new tests, and installing the distribution packages on real hardware to debug issues.

A Security Model for systemd (asg2025) 40:31

לפני 9 ימים40:31

40:31

Linux lacks a coherent security model, and by extension we never defined one for the systemd project either. In this talk I'd like to start changing this, and begin defining some general security design guidelines that we so far mostly followed implicitly, and make them more explicit. After all, systemd to a large degree is involved in security subsystems, from SecureBoot, Measured Boot & TPM, to its service sandboxing, dm-verity/dm-crypt support, its FIDO2/PKCS#11 hookups, its many security boundaries, secure parameterization, Linux Security Module initialization and more. While this distributions & applications consuming systemd might follow different security models I think it's important to talk about a unified vision from the systemd upstream perspective, even if various downstreams then make modifications or only deploy a subset of it.

New Linux Kernel Coredump Infrastructure (asg2025) 41:04

לפני 8 ימים41:04

41:04

Coredumping on Linux has long been a nightmare. Currently two modes are supported: (1) Dumping directly into a file somewhere on the filesystem. (2) Dumping into a pipe connected to a usermode helper process spawned as a child of the system_unbound_wq or kthreadd. For simplicity I'm mostly ignoring (1). There's probably still some users of (1) out there but processing coredumps in this way can be considered adventurous especially in the face of set*id binaries. The most common option should be (2) by now. It works by allowing userspace to put a string into /proc/sys/kernel/core_pattern like: |/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h The "|" at the beginning indicates to the kernel that a pipe must be used. The path following the pipe indicator is a path to a binary that will be spawned as a usermode helper process. Any additional parameters pass information about the task that is generating the coredump to the binary that processes the coredump. In the example core_pattern shown above systemd-coredump is spawned as a usermode helper. There's various conceptual consequences of this (non-exhaustive list): - systemd-coredump is spawned with file descriptor number 0 (stdin) connected to the read-end of the pipe. All other file descriptors are closed. That specifically includes 1 (stdout) and 2 (stderr). This has already caused bugs because userspace assumed that this cannot happen (Whether or not this is a sane assumption is irrelevant.). - systemd-coredump will be spawned as a child of system_unbound_wq. So it is not a child of any userspace process and specifically not a child of PID 1. It cannot be waited upon and is in a weird hybrid upcall which are difficult for userspace to control correctly. - systemd-coredump is spawned with full kernel privileges. This necessitates all kinds of weird privilege dropping excercises in userspace to make this safe. - A new usermode helper has to be spawned for each crashing process. On recent kernels a new mode has been added making use of AF_UNIX sockets. This talk will talk about the new modes, how they can be used, what advantages they have in comparison to the other modes, and look at technical implementation details.

Slim device software with systemd targets and nspawn (asg2025) 24:23

לפני 8 ימים24:23

24:23

It has been 10 years since Axis Communications had a presentation at the systemd conference. Back then, we have shown how we have increased our product quality, stability and boot times by porting our platform to systemd. 10 years later, we had different challenges to keep the resource usages and boot times under control. We have started from bottom up and sliced our software for this purpose. This work also got us inspired to create virtual versions of our hardware products that we cluster deploy using systemd's nspawn. We have hundreds of engineers working on a software platform that is the base for different product types. It is a different challenge to keep the resource usages of different software composition when so many independent engineers collaborate together. We have applied a different strategy to keep our products as slim and as optimized as possible using different systemd principles like targets, slices, resource prioritization. As a side effect of this work, we have started from ground up and started to virtualize our products using systemd-nspawn. The next step for us was to figure out how in best way to cluster deploy our virtual products so that we can increase the quality of our end to end systems.

GNOME OS' prêt-à-booter image (asg2025) 26:05

לפני 8 ימים26:05

26:05

GNOME OS is a distribution based around systemd-sysupdate. This year, we finally created a live installer image using the same /usr partition as the installed OS. The main innovation however is the ability to install without the need to reboot. The user can start working while the installation is happening. This live image is built using systemd-repart. And the installer itself also uses systemd-repart. But systemd-repart is not the complete solution and we had to solve some challenges.

Unprivileged Containers, with Transient User Namespaces and ID Mapping, but Without SETUID Binaries (asg2025) 41:53

לפני 8 ימים41:53

41:53

Many traditional container engines make use of the "subuid" concept and the "newuidmap" tool to implement a concept of "unprivileged" user-namespace containers on Linux. This approach has many shortcomings in my PoV, from both a security and scalability standpoint. Recent systemd versions provide a more powerful, more secure, mor scalable alternative, via systemd-nsresourced, systemd-mountfsd and other components. In this talk I want to shed some light on the problems with the "old ways", and in particular focus on what the "new ways" bring to the table, and how to make use of them in container runtimes.

Shipping Flatpak applications with an image based system (asg2025) 27:58

לפני 8 ימים27:58

27:58

Flatpak is the de-facto standard for distributing desktop applications across various Linux based systems. It also offers other advantages such as sandboxing. It is particularly useful for image based systems as it installs the applications into a separate location and doesn't try to modify the system. GNOME OS is GNOME's development, testing and QA operating system. It builds the latest and greatest in-development versions of the GNOME desktop and core applications. It is also Linux based system that tries to fully embrace the systemd ecosystem. The applications are however built into the system. While this might be great for testing the apps as they would be in most distros, we also want to build our Flatpak applications from the same build definitions and our users (or more correctly early adopters) prefer to use Flatpak for various reasons. In this talk we'll explore what other image based distributions do to provide Flatpak applications to their users, what users expect from "Flatpak applications" and the various proposals for implementing that in GNOME OS. We hope to be able to present our end result by the time of the conference.

At Meta, we've been looking to revamp our internal container runtime (Twine). Instead of maintaining all the low level container runtime code ourselves, we'd much prefer having more of this managed by systemd. This talk will go over what we did to make systemd transient units a suitable environment for running system containers (pid namespace support, cgroup namespace support, namespace delegation, ...), and why we went this route instead of reusing systemd-nspawn.

Verification of OS artifacts without stateful keyrings (asg2025) 21:40

לפני 8 ימים21:40

21:40

Many OS artifacts today are still verified using proprietary, stateful keyring formats. With the "File Hierarchy for the Verification of OS Artifacts (VOA)" an attempt is made to rid the ecosystem of this limitation by implementing a generic lookup directory. With extensibility in mind, this unifying hierarchy currently provides integration for OpenPGP, with further integrations in planning. While working on improvements to the [ALPM](https://alpm.archlinux.page) ecosystem, the way packages and other OS artifacts are currently verified on Arch Linux has been evaluated. Noticing the extensive vendor lock-in to GnuPG and with today's widespread availability of [Stateless OpenPGP](https://wiki.archlinux.org/title/Stateless_OpenPGP) implementations in mind, a plan was hatched to create a more generic, stateless approach. A specification and implementation for the [UAPI group](https://uapi-group.org/) has been started to create a ["File Hierarchy for the Verification of OS Artifacts (VOA)"](https://github.com/uapi-group/specifications/pull/134). This approach is meant to be technology agnostic and allow further integrations, such as SSH and X.509. Follow along for an overview of what this specification is trying to improve upon and how today's tools could benefit from it in the future.

19:42

Simplify systemd management with `isd`! `isd` is a TUI offering fuzzy search for units, auto-refreshing previews, smart sudo handling, and a fully customizable interface for power-users and newcomers alike. If you ever became frustrated while typing: - `systemctl start --user unit-A.service` (manually starting a unit) - `systemctl status --user unit-A.service` (seeing that it failed) - `journalctl -xe --user -u unit-A.service` (checking the logs) - `systemctl edit --user unit-A.service` (updating the unit) - (repeat until problem is solved) `isd` could help. In this presentation, we will discuss the features that `isd` currently supports, the features that are planned for the future, and the experience of developing a TUI for `systemd` commands. I hope attendees will find the content engaging and practical. Audience participation is highly encouraged. I am especially eager to hear your thoughts, ideas, and feature requests. If you think a tool like `isd` might be unnecessary or redundant, I'd love to hear your perspective, too!

For many years, firewall solutions on Linux have grown and evolved, without any major change, until eBPF. While eBPF can allow very fast and efficient packet filtering, the learning curve doesn't make it easily accessible to non-developers. bpfilter aims to bridge the gap between existing tools (nftables, iptables) and modern technologies such as eBPF. By translating filtering rules into native code, bpfilter abstracts the complexity behind cutting-edge kernel technologies while maintaining backward compatibility with existing solutions. Let's discuss about bpfilter and see it in action!

Integrating systemd-sysext images in an update stack (asg2025) 26:19

לפני 9 ימים26:19

26:19

systemd-sysext provides a nice way to enhance a distribution with a read-only root filesystem without the need to reboot. But there is additional tooling necessary to manage the sysext images: * install an image which is compatible with the installed OS version * update installed images to the newest compatible version * rollback images in case of an OS rollback * cleanup unneeded images In this presentation I will talk about which tooling systemd itself provides for this (importctl, updatectl, ...) and what the benefits and disadvantages of this tools are compared with real world use cases. In the end I created an own, generic and distribution independent tool for this using systemd tools in the backend. Using openSUSE MicroOS as example I will demonstrate how we solved the problems with it and how we integrated it in our update stack.

Sandboxing services with Landlock (asg2025) 25:01

לפני 9 ימים25:01

25:01

Landlock is an unprivileged kernel feature that enables all Linux users to sandbox their processes. Complementary to seccomp, developers can leverage Landlock to restrict their programs in a fine-grained way. While Landlock can be used by end users through sandboxer tools, there is currently no well-integrated solution to define security policies tailored to system services. Although AppArmor and seccomp security policies can already be tied to a system unit, we aim to provide a more dynamic, standalone, and unprivileged option with Landlock. In this talk, we'll briefly explain what Landlock is and highlight its differences from other Linux security features (e.g., namespaces, seccomp, other LSMs). We'll then focus on the new configuration format we are designing for Landlock security policies, its characteristics, and how it could extend systemd units by taking into account runtime context (e.g., XDG variables).

The End of the World as we know it? (DS2025) 46:24

לפני 17 ימים46:24

46:24

Wie TechBros die Zukunft planen und weshalb wir diese Zukunft stoppen, um Planeten & Gesellschaft zu erhalten Moderne Technologie wie „KI“ werden uns durch eine Vielzahl an Versprechen schmackhaft gemacht: Die künstliche Intelligenz macht alles noch viel besser. Fortschritt, permanente Verbesserungen, die beste Zukunft aller Zeiten. Beim näheren Hinsehen sind diese Versprechen aber extrem unkonkret: Wohin wir durch die Nutzung dieser Technologien fortschreiten, für wen sich alles permanent verbessert und wie viele von uns an der als beste Zukunft beschriebenen Zustand teilhaben dürfen, wird nie erklärt. Wer diese Versprechen hingegen nicht begeistert umarmt gilt schnell als technikfeindliche:r Hinterwäldner:in. Dabei ist ein Hinterfragen der Versprechen enorm wichtig, denn hinter Technologien wie ChatGPT und Gotham stehen Firmen wie OpenAI und Palantir. Und hinter diesen und anderen Firmen Menschen mit Ideen und Ideologien. Und Milliarden auf den Konten. Sie haben, im Gegensatz zu uns, sehr genaue Vorstellungen davon, wohin es gehen soll und welche Teile der Menschheit an ihrer Zukunft teilhaben werden dürfen. Machtkonzentrationen, die theoretisch durch soziale Entwicklungen nicht mehr möglich sein sollten, haben sich in den letzten Jahrzehnten gebildet und wenige Einzelpersonen greifen mit ihren Entscheidungen die Schicksale und Entwicklungen von Milliarden Menschen ein. In ihrem Vortrag gehen HonkHase und Katika Kühnreich auf die grundlegenden Glaubenssysteme der nun oft Tech Bros genannten Milliardär:innen und auf die Auswirkung ihrer Technologien auf Gesellschaften ein, mit einem Schwerpunkt auf der Überwachungssoftwarefirma Palantir des Investors Peter Thiel. Die kybernetische und rassistische Vergangenheit trifft auf eine verdrogte Gegenwart sowie auf eine zerbröselnde Gesellschaft, die durch viel Propaganda und Gamifizierung der sogenannten Sozialen Medien vergessen hat, dass sie selbst eine Macht ist. Den TESCREAL genannten Zukunftsvisionen der Tech Elite werden die Grundlagen von fairen, selbstorganisierten Gesellschaften entgegengestellt. #TESCREAL #Transhumanismus #TechBros #SozialeBewegungen #Mitbestimmung Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://talks.datenspuren.de/ds25/talk/8H9TE9/…

How to Construct a more Decentralized Internet? (DS2025) 31:54

לפני 17 ימים31:54

31:54

This talk reports about Dresden Internet Exchange (DD-IX), how it was build, why it was necessary and lessons that we learned. The infrastructure of the Internet is becoming increasingly centralized by large Internet and content providers and Internet Exchanges. As a result, packets have to travel hundreds of kilometers, even if the sender and receiver are located in the same city. This causes increased latency and makes the Internet more susceptible to disruptions. With DD-IX, we want to do our part to counteract this development. DD-IX is run by an active community of students, network engineers, and volunteers. In this presentation, we will report on our journey and the insights we have gained along the way.

Freie Sachsen - Wie es der sächsischen Neonazi-Szene gelungen ist, sich neu zu organisieren (DS2025) 44:43

44:43

Alter Wein in neuen Schläuchen - wie es den Freien Sachsen gelungen ist, die Neonazi-Szene in Sachsen neu zu organisieren. Seit der Corona-Pandemie hat sich die sächsische Neonazi-Szene stark verändert. Die NPD verlor ihre zentrale Stellung spätestens mit ihrer Umbenennung in "Die Heimat", gleichzeitig blieb das Aktivitätsniveau der rechten Szene hoch. Durch die Corona-Proteste hat mit den "Freien Sachsen" ein neuer Akteur die Funktion als wichtigste Partei der sächsischen Neonazis übernommen - jedoch mit einigen skurrilen Eigenheiten wie der Forderung eines "Säxit". Wir zeigen in unserem Vortrag, wie es den "Freien Sachsen" gelungen ist, für das breite Spektrum der sächsischen radikalen Rechten - vom DDR-nostalgischen Russland-Fanatiker bis zur Elblandrevolte - die Funktion als zentrales Schanier einzunehmen. Dazu beleuchten wir, wer hinter den "Freien Sachsen" steckt, welche Strategien sie nutzen, und warum sie gefährlich und ernst zu nehmen sind.

Beginners Guide to IC Reverse Engineering – With a High Likelihood of Survival! (DS2025) 45:44

לפני 18 ימים45:44

45:44

Peel back IC layers: decapping, delayering, imaging, and analysis for curious beginners. My curiosity often knows no bounds, especially when it comes to understanding how things work. That’s why I’ve often wondered how certain ICs function internally and how one can uncover their secrets. This curiosity led me to start exploring the world of chip reverse engineering, even without any prior experience. After several mishaps (and a few rather risky experiments), I finally achieved my first results and found myself falling ever deeper down the rabbit hole. While researching techniques, I discovered the Siliconpr0n community—a group of brilliant, friendly, and incredibly helpful fellow nerds who shared their knowledge and made the steep learning curve much more manageable. In this talk, I will show how to "safely" decap and delayer chips with minimal effort—often right at your kitchen table, or better, in a well-ventilated space such as a balcony. I will introduce the essential tools and techniques for beginners, demonstrate how to capture usable images, and explain simple methods for analyzing chip structures. The presentation will include practical examples from the Siliconpr0n community and provide insight into the current projects of others.

Magical AI World? Resources & Labour & „AI“ and how it is changing societies (DS2025) 45:27

לפני 18 ימים45:27

45:27

AI is a buzzwords: AI makes everything better, brings all solutions, will save us. But what is AI and where will it save us to? Artificial Intelligence became a buzzword and is currently stuck to nearly everything that can’t climb a tree fast enough. As if by magic all becomes easier, faster, and more effective when you apply “AI”. And much better, especially in comparison to a human doing the task. One small click for a human and “AI” is magically solving our tasks: our (home-)work, writing our emails and is bringing our rooms to the cosiest temperature. “AI” is the rescue if not the salvation and often we do not have to pay a penny for that! But what kind of picture is appearing if you take a look behind the curtain of the “AI Magic”? Because we are all old enough to know that every magic is based on tricks. And that first thing you ought to do is to check the gift horses teeth. This talk will lift the curtain of the “AI Magic”. By asking what is meant by the term “AI”, what differs “AI” from human intelligence? If it is the rescue – where is it rescuing us to? In what kind of society are we let by “AI” and its founders? And do we want to be there? This talk will tackle the root of the problem by digging out the ideological roots of AI by taking a look at three different aspects: resources, conditions of labour, and the shift of power happening through that technology. The origins of “AI” will be the topic of the first chapter. Because “AI” did not suddenly hatch, but was developed. Behind the development are theories, money, and and a concept of the human nature and society. And, in the case of “AI”: how to change it by using “AI”. Following this introduction, “AI”’s spell will be broken in the following steps: Regarding the planet’s dwindling resources, the working conditions of “AI”, and the societal implications and changes that are triggered by these technologies. Computer parts do not grow on trees, the production needs loads of resources – energy, commodities, and water. As well as heaps of human labour, mostly under gruesome conditions. In this part of the talk finiteness will be addressed, both of the human and the planets resources. Climate change will be broached as well as (the fragility) of global supply chains and dependencies. The next chapter will pick up the thread of working conditions connected to “AI”. Because not only in the procution of hardware, but in the training of the software are countless humans are involved, often working under brutal conditions. And there is a global trend showing: “The North” is making money while “the South” suffers. And because not all shiny stuff is gold this part will take a look on some “AI” that was not magic“AI” at all dirty tricks. The last part the implication on the society will be sketched. What happens when a technology that calculation processes are so opaque gain so much power? If people controlling these processes are not controlled by anyone? How does it change our lives, our labour, our social interactions with other humans, our political work? And how does a society controlled by tech moguls or Tech Bros will look like? The more power we shift to technologies like “AI” and their owners, the more we should ask ourselves what the owners of those technologies want and if we want to be part of that.

Digitale Gewalt: feministische Cybersecurity als Brückenbauprojekt (DS2025) 30:37

לפני 18 ימים30:37

30:37

Bei digitaler Gewalt aus dem sozialen Nahraum braucht es feministische Cybersecurity und eine Brücke zw. IT und sozialer Arbeit. Digitale Gewalt ist heute Alltag in Beratungsstellen und häufig eine Fortsetzung von analoger Gewalt im sozialen Nahraum: Wenn (Ex-)Partner mit versteckten Tracking-Apps kontrollieren, intime Fotos veröffentlichen oder Identitäten gestohlen werden; oder wenn Kolleg*innen am Arbeitsplatz digitale sexualisierte Gewalt erleben. Digitale Gewalt scheint schwer greifbar, doch ihre Folgen sind für die Betroffenen gravierend: Angstgefühle, soziale Isolation und Verlust von Teilhabe, ständiges Kontrolliertwerden, Rufschädigung uvm. Dabei ist erkennbar, dass es eine deutliche Geschlechtsspezifik gibt. Obwohl Technik eine zentrale Rolle spielt, wird sie in der Debatte häufig als neutral betrachtet. Doch Technik ist nicht neutral. Sie wird in Machtverhältnissen entworfen und oft von privilegierten Gruppen gestaltet. Klassische Cybersecurity schützt Systeme, Daten oder Netzwerke vor Angriffen von außen. Aber wer schützt Menschen in diesen Systemen vor digitaler Gewalt in ihrem sozialen Nahraum? Hier gibt es Bedrohungen, die in der Entwicklung oft nicht mitgedacht werden. Feministische Cybersecurity setzt genau hier an: Sie versteht Sicherheit nicht als objektiv oder rein technisch, sondern als etwas Soziales, Kontextspezifisches und Alltagsnahes. Sie fragt: Wer hat Zugriff? Welche Perspektiven werden übersehen? Welche Bedrohungen werden normalisiert? Das Hinterlassen von Datenspuren bedeutet bei Partnerschaftsgewalt oft eine erhöhte Gefahr von körperlicher Gewalt, Machtausübung und Kontrolle. Tools müssen also so entwickelt werden, dass sie Schutz ermöglichen und Kontrolle verhindern. Damit das gelingen kann, müssen Brücken gebaut werden: Zwischen IT-Communities und Beratungsstellen, zwischen technischer Expertise und Wissen über geschlechtsspezifische Gewalt. Beratungsstellen verstehen die Dynamiken von Gewalt, aber nicht immer, wie AirTags, Messenger oder Cloud-Dienste zur Kontrolle genutzt werden. Entwickler*innen kennen Tools und Protokolle – aber oft nicht die Lebensrealitäten von Betroffenen. In unserem Beitrag zeigen wir, warum diese Brücken notwendig sind, und wie sie aussehen könnten: durch einwilligungsorientiertes Design, verständliche Sicherheits-Tools, betroffenenzentrierte Entwicklung und Wissenstransfer zwischen verschiedenen Fachrichtungen. Denn nur gemeinsam können wir daran arbeiten, digitale Räume sicherer zu gestalten – für alle. Nach einem ca. 30-Minütigen Vortrag soll der Raum für Fragen und Anregungen aus dem Publikum geöffnet werden. Das Projekt „Aktiv gegen Gewalt“ beim Bundesverband der Frauenberatungsstellen und Frauennotrufe (bff) widmet sich seit 2017 dem Umgang mit digitaler geschlechtsspezifischer Gewalt. Im Fokus stehen Information und Weiterbildung für Sozialarbeiter*innen, politische Interessenvertretung und Öffentlichkeitsarbeit.

Git-basierte sachliche Online-Diskussionen (DS2025) 47:12

Online über kontroverse Themen zu diskutieren ist schwierig. Das hat strukturelle Gründe, die sich aber überwinden lassen. Über digitale Medien geführte Diskussionen zu kontroversen Themen verlaufen selten zufriedenstellend. Der Vortrag basiert auf der Überzeugung, dass diese miese Online-Diskussionskultur die Errungenschaften der FDGO gefährdet und autoritäre Bestrebungen begünstigt. Und er basiert auf der These, dass daran nicht (ausschließlich) die Einfältigkeit *uder* Böswilligkeit der jeweils anderen Seite Schuld sind, sondern dass es strukturelle Gründe für misslingende Diskurse gibt. Einige dieser Gründe werden im Vortrag näher analysiert und darauf basierend ein prototypischer **Lösungsansatz** für bestimmte Anwendungsfälle vorgestellt: "[fair-debate](https://fair-debate.kddk.uber.space/about/)" zerlegt einen Text-Beitrag automatisch in einzeln referenzierbare Sätze, die separat beantwortet werden können, sodass der **Originalkontext** stets erhalten bleibt. Zudem werden die Inhalte aller Diskussionsteilnehmer:innen in **Git-Repos** getrackt wodurch eine Manipulation verhindert und die Neutralität der Diskussionsplattform sichergestellt wird.

Push-Benachrichtigungen auf Android-Handys ohne Google. Dezentralisiert und Open Source. Mit Open Source Tools wie microG bekommt man zwar erfolgreich proprietäre Google Software von seinem Android-Handy verbannt; die eigentlichen Benachrichtigungen werden aber dennoch über Google Server verschickt (Firebase Cloud Messaging). UnifiedPush ist ein Framework, mit dem Push-Benachrichtigungen dezentral bzw über selbst betriebene Server zugestellt werden können. Zahlreiche Open Source Android Apps unterstützen bereits UnifiedPush. Unter anderem: Tusky, Fedilab, DAVx⁵, Fennec, Element (mit Einschränkungen) und viele mehr. Dieser Vortrag erklärt, wie Push-Benachrichtigungen im Allgemeinen funktionieren und warum sie trotz ihres eventuell schlechten Rufes eleganter sind, als jede App eine eigene Serververbindung aufbauen zu lassen. Des Weiteren werden mögliche Privacy-Probleme erörtert die mit der Benutzung von Google Push Servern einhergehen. Anschließend wird die Architektur von UnifiedPush erklärt. Der Vortrag endet mit einer praktischen Anleitung wie man UnifiedPush auf einem Android-Handy benutzt.

fact your fear - Macht mit! Lösen wir Gemeinschaft. (DS2025) 42:31

לפני 19 ימים42:31

42:31

Eine langfristige und konstruktive gesamtgesellschaftliche Lösungsfindung ist (aktuell nicht) möglich. Oder doch? Eine langfristige und konstruktive gesamtgesellschaftliche Lösungsfindung ist (aktuell nicht) möglich. Obwohl viele Akteure sich dafür konstruktiv einsetzen und/oder sogar entgeltlich dafür einsetzen sollten. Die Angst-Biologie und Aufmerksamkeits-Ökonomie in Verbindung mit rein wirtschaftlichen Überlegungen lassen die Priorisierung einer kurzfristigen Gewinn-Orientierung zu. In der heutigen Informationsgesellschaft stehen wir vor der Herausforderung, dass der Diskurs häufig von verschiedenen Faktoren beeinflusst wird, die unsere Wahrnehmung und Entscheidungsfindung beeinflussen. Hierbei spielen kognitive Verzerrungen, die Angst-Biologie und eine emotionale Diskussionskultur eine entscheidende Rolle. Zudem zeigen kleinteilige Reaktionen der Diskussionsteilnehmer, dass viele wichtige Argumente im Lärm der Meinungen verloren gehen. Nicht nur, dass gute Argumente häufig untergehen - Widersprüche werden nicht ausreichend wahrgenommen. Was wäre wenn es eine Fakten- und Meinungs-Landkarte gäbe? Tinder-your-Meinung -und- lasse uns darüber im Kontakt bleiben! Akteure können Wissen teilen, Stimmungsbild erkennen und Optionen anbieten. Wie wäre es mit Gegenfragen, Widersprüchen, passenden Fakten und Handlungsoptionen wie Petitionen? Fact-your-Fear ist der POC für eine solche Plattform. Können wir annehmen, dass weniger als 10 spezifische Themen die Meinungsbildung dominieren? Sind also folgendene Beobachtungen realistisch: · Weniger als 10 Themen bestimmen die Meinung von Individuen und Gruppen. · Weniger als 10 Prozent der „Gegen-Argumente“ verfangen und beeinflussen den Diskurs nachhaltig. · Weniger als 10 Argumente machen bis zu 90 Prozent des Outcomes einer Diskussion aus. Stellen wir uns vor, wir könnten eine Plattform schaffen, auf der Themen, Argumente, Gegen-Argumente, Aussagen, Gegenfragen und Meinungswechsel verfügbar und vergleichbar wären. Widersprüche ließen sich detektieren, dokumentieren und leicht präsentieren. 1. Themen: Eine strukturierte Übersicht der diskutierten Themen würde es ermöglichen, den Diskurs gezielter zu beeinflussen und Themenvielfalt zu fördern. 2. Argumente: Transparente Argumente könnten stärker in den Vordergrund gerückt werden, was zu einer differenzierteren Argumentation führen würde. 3. Gegen-Argumente: Eine gezielte Sichtbarkeit von Gegen-Argumenten würde sicherstellen, dass diese nicht im Schatten der Mehrheitsmeinung verloren gehen. 4. Aussagen: Klar formulierte und überprüfbare Aussagen könnten den Diskurs objektivieren und emotionale Verzerrungen reduzieren. 5. Gegenfragen: Die Etablierung einer Kultur des Hinterfragens könnte dazu beitragen, Meinungen zu hinterfragen und zu verfeinern. 6. Meinungswechsel: Ein Prozess, der es ermöglicht, Meinungen leichter zu ändern, könnte zur Stärkung der offenen und objektiven Diskussionskultur beitragen. Indem wir Diskussionen fundierter und transparenter gestalten, können wir kognitive Verzerrungen minimieren, Ängste abbauen und eine emotionale Diskussionskultur etablieren, die auf gegenseitigem Respekt und Verständnis basiert. Wir möchten gemeinsam an einem Diskurs arbeiten, der nicht von kleinteiligen Reaktionen, sondern von klaren und überzeugenden Argumenten geprägt ist.

Licht an gegen die „Going Dark“ Überwachungsagenda (DS2025) 35:35

לפני 19 ימים35:35

35:35

Wir dekonstruieren das „Going Dark“ Narrativ und schauen, welche Überwachungsmaßnahmen damit gerade propagiert werden. In letzter Zeit wird ein Narrativ wieder viel strapaziert: „Going Dark“. Die Erzählung geht so: Die "Guten", hier Strafverfolgungsbehörden" tappten bei ihren Ermittlungen vermeintlich im Dunkeln, während die Bösen, z.B. 'CYBERkriminelle' neue technische Entwicklungen nutzten. Die Schlussfolgerung sind dann Forderungen nach mehr Überwachung. Diese Erzählung spart dabei aus, dass es heute schon mehr Möglichkeiten zur staatlichen und kommerziellen Überwachung gibt als je zuvor. Trotzdem hält sich das „Going Dark“ Narrativ hartnäckig. Darum wollen wir in dem Vortrag einen Blick auf die Fragen werfen: * Wo kommt diese Erzählung eigentlich her und wie begleitet sie uns schon seit Jahrzehnten? * Was hat es mit der Arbeitsgruppe HLG „Going Dark“ der EU auf sich und welche Überwachungsmaßnahmen kommen dort im Rahmen der neuen EU Strategie für Innere Sicherheit auf uns zu? * Und was passiert eigentlich, wenn wir das „Going Dark“ Narrativ mit der Realität konfrontieren? Welche Evidenz gibt es für diese Erzählung? Ist wegen Verschlüsselung jetzt plötzlich alles in Gefahr und die Polizei blind? Oder stimmt das doch nicht? Achtung: Diese Session kann Spuren von ProtectEU, Chatkontrolle, Vorratsdatenspeicherung und anderen fehlgeleiteten Politikansätzen enthalten.

Das gläserne Baby? Unbeabsichtigte und unvorhergesehen Effekte der Speicherung genomischer Daten von Neugeborenen (DS2025) 32:37

לפני 19 ימים32:37

32:37

Sollte das Genom aller Neugeborenen in Deutschland sequenziert, analysiert und ggf. langfristig gespeichert werden? Genetische Daten werden in der Medizin für Diagnostik und Gesundheitsvorsorge immer wichtiger. Sie enthalten jedoch hochsensible Informationen über biologische Verwandtschaften, Gesundheitsrisiken, Behinderungen und Abstammung. Zudem wollen Forschende auch Verhalten und Persönlichkeitsmerkmale aus DNA-Daten vorhersagen können – das Risiko für Stigmatisierung und Diskriminierung ist also groß. Dem technologischen Fortschritt folgend werden momentan international Pilotstudien auf den Weg gebracht, bei dem das etablierte Neugeborenen-Screening durch eine genomisches Screening ersetzt werden soll. So soll eine Vielzahl angeborener Erkrankungen früh diagnostiziert und therapiert werden können. Auch in Deutschland wird über die Einführung eines solchen bevölkerungsweiten Screenings diskutiert. Es wird auch in den Raum gestellt, die Gendaten der Babys für eine sekundäre Datennutzung langfristig zu speichern. Dies würde indirekt eine nationale DNA-Datenbank schaffen. Zudem ist ungeklärt ob die Daten auch in die elektronische Patientenakte und in den Europäischen Gesundheitsdatenraum fließen würden, wo sie privatwirtschaftlich beforscht werden könnten. Durch den sensiblen Informationsgehalt von genetischen Daten sind diese Pläne mit erheblichen ethischen Problemen verbunden. Außerdem ist DNA unveränderbar und ein lebenslanger Identifikator. In meinem Vortrag möchte ich einige Probleme beleuchten, die mit einer solchen systematischen Sammlung genetischer Bevölkerungsdaten verbunden sind, grade auch im Hinblick auf die sich verändernde politische Landschaft.

Freeze. Flight. Fight. Fawn: Queer Survival in Wartime Ukraine (DS2025) 21:47

לפני 19 ימים21:47

21:47

Lives of queer Ukrainians reshaped by war — from the frontlines to exile, rebuilding community under constant uncertainty. This talk is a mosaic of stories from queer people whose lives changed irreversibly after Russia’s full-scale invasion of Ukraine on February 24, 2022. Some volunteered for the frontline and survived captivity, some became refugees abroad, and others chose to return home to rebuild their communities despite the danger. As the war broke out, these people suddenly found themselves in a reality where human rights no longer applied. Not only rights and dignity were now at stake, but life itself. Survival — and protecting their loved ones — once again became a daily task. The talk brings the audience close to the lives of soldiers facing homophobia even at the front, people navigating life in exile without language or networks, and those who, against all odds, return to rebuild what was lost. Through personal testimonies and fragments of interviews, it offers a rare glimpse into experiences often absent from official narratives. This presentation is part of an ongoing project that also includes a forthcoming art exhibition and documentary installation by Ukrainian queer artists, planned for next year.

Network-Attached-Storage-Geräte (NAS) haben netteres Design als Selbstbaulösungen, aber gruselige Software. Lets replace it. Die großen NAS-(network attached storage)-Hersteller (QNAP, Synology, usw) sind berüchtigt für immer wieder auftretende Sicherheitslücken in deren Standard-Software. Trotzdem ist die spezialisiertere Hardware interessant und hat zumindest in der Gerätegröße und auch den hotplug-Laufwerksschächten einen Vorteil gegenüber einem Selbstbau-Projekt. Im Vortrag möchte ich also zeigen, wie interessant die Hardware selbst ist, aber auch wie gruselig die Standardsoftware daher kommt. Und wie ich die Software auf dieser einen Qnap NAS-Familie vollständig ersetzt habe, sodass von der Herstellersoftware nichts mehr auf dem Gerät übrig ist, sondern alles nach dem Boot-ROM der CPU unter eigener Kontrolle steht - und abgesehen von ein paar wenigen letzten Baustellen auch (fast) alles Freie Software ist.

Eine Reise, in eine Zeit, als man zum Telefonieren noch in eine Telefonzelle gehen und dort so komische Plastekarten in das Telefon stecken musste. Es ist eine Zeitreise in vielerlei Hinsicht. Hauptsächlich soll es darum gehen, wie sich die Telefonkarten entwickelten und wie sie (in verschiedenen Ländern) funktionierten. Allerdings ergab sich aus den Recherchen auch eine Reise in das Internet der 90er Jahre. Ich werde zeigen, was die Karten für Daten beinhalten und wie man sie heute noch auslesen kann, um damit die Frage zu beantworten: "Ist da noch was drauf?" Dabei gehe ich auch auf verschiedene Hardware und deren Programmierung ein.

Das Fediverse in der Digitalpolitik (DS2025) 41:35

לפני 18 ימים41:35

41:35

Dieser Talk beleuchtet digitalrechtliche Entwicklungen, die das Fediverse betreffen, und diskutiert Forderungen an die Politik. Trotz der unfreiwilligen PR-Coups von Tech-Milliardären und dem sich ausbreitenden Faschismus in den USA fristet das Fediverse immernoch ein Nischendasein. Dabei könnten diese freien, dezentralen sozialen Netzwerke eine Alternative sein, die unsere Demokratie stärkt und schützt. Die Digitalpolitik der EU legt den Fokus meist darauf, die großen Tech-Konzerne zu regulieren und deren schwerste Rechtsverstöße einzudämmen – und scheitert damit sogar noch. Dabei werden die Herausforderungen für das Fediverse selten mitgedacht. Es fehlt bisher auch an konkreten Vorschlägen, wie das Recht als Hebel eingesetzt werden könnte, um dem Fediverse zum Erfolg zu verhelfen. Dieser Talk wirft einen Blick auf die aktuellen rechtlichen und politischen Entwicklungen, die das Fediverse betreffen. Es werden mögliche Stellschrauben im Recht identifiziert, mit deren Hilfe das Fediverse gestärkt werden könnte. Damit soll ein Beitrag zur Diskussion geleistet werden, mit welchen Forderungen die Fediverse-Community sinnvollerweise auf Gesetzgebungsprozesse einwirken könnte.

Verteilte Scharniere zwischen Maintainer:innen und Industrie (DS2025) 45:06

לפני 18 ימים45:06

45:06

Wie wir die Industrie an der Care-Arbeit für ihre FOSS-Abhängigkeiten beteiligen. Moderene Software-Entwicklung ist ohne die Verwendung von Open Source Bausteinen nicht mehr denkbar, 97% aller kommerziellen Code-Basen enthalten Open Source. Gleichzeitig beteiligen sich selbst Unternehmen mit hohen Gewinnen nur wenig an der notwendigen Wartung und Weiterentwicklung dieser Komponenten. Mit dem Cyber Resilience Act (CRA) der EU wird nun erstmals eine Regulierung eingeführt, die Hersteller verpflichtet, die eingesetzten FOSS-Komponenten zu prüfen und auch für solche Sicherheitslücken gradezustehen, die in diesen Abhängigkeiten gefunden werden, in den meisten Fällen für 5 Jahre. Wie dies in der Praxis dann durch die Unternehmen umgesetzt werden kann, wenn jedes Unternehmen viele hunderte oder tausende Abhängigkeiten im Blick behalten muss, und auf der anderen Seite Maintainer:innen mit potentiellen Anfragen von den vielen hundert oder tausenden Konsumenten ihrer Komponenten konfrontiert sind, ist jedoch noch völlig offen. In diesem Talk möchte ich unterschiedliche Szenarien diskutieren und insbesondere dezentrale, kooperativ organisierte Stewards betrachten, die die Care-Arbeit kollektiv organisieren und sicherstellen, dass tatsächlich Maintainer:innen vom CRA profitieren.

55:25

Melodic Death Metal aus Dresden Fünf (6) aufstrebende, aber erfolglose Musiker verzücken und/oder verletzen eure Ohren mit ihrem vielschichtigen, modern-melodischen Todesmetall. Doch dieser Schublade setzen sie mit Einflüssen fast aller extremen Metal-Richtungen stets gekonnt die Cocktail-Kirsche auf den Scheißehaufen. Inhaltlich stets auf der Gratwanderung zwischen Bullshit und Wahrheit, aber immer mit einer kleinen Prise humanistischer Menschenverachtung. Neben zwei sich selbst überschätzenden Gitarristen drängen sich die Sänger stümperhaft in den Vordergrund, während der Bassist im Rhythmus sabbert und der Schlagzeuger mit Abwesenheit glänzt. Und da sie lieber Musik spielen, anstatt Pressetexte zu schreiben, hört sie euch doch einfach an!

Appease movement - Why the German Peace Movement fails to condemn Russia's Aggressive War against Ukraine (DS2025) 44:39

לפני 18 ימים44:39

44:39

Analysis from a naive peace activist who grew up and got wise. In 2014, Russia assulted Ukraine and in 2022, it started its full-scale invasion. The major part of the peace movement in Germany, however, not only stayed silent but even aggressively spreads Russian war propaganda narratives. Why? Way too many things about this russian aggression are counterintuitive. Our first and logical reaction may well turn out deceitful. However, such discrepancy has a logical explanation. Kupferkobold is a peace activist who also fell for such fallacy before he "switched sides" to become a Ukraine supporter. He is going to share his story, explain the strategic failure of the German peace movement, how Russian propaganda hacks the gaps in our perception to re-program our intuition and how to immunize oneself against it.

Lowlights aus dem Überwachungssommer 2025 (DS2025) 36:57

לפני 18 ימים36:57

Ob EU-, Bundes- oder Länder-Ebene: überall gibt es neue Pläne, uns alle zu überwachen. Lasst uns diese genauer beleuchten! Neue Vorstöße zur Chatkontrolle und zur Vorratsdatenspeicherung auf EU-Ebene, ein geplantes bundesweites Register für Menschen mit psychischen Erkrankungen, Palantir für BaWü und noch vieles mehr. Unsere Welt wird nicht nur immer rechter, sondern soll auch immer mehr überwacht werden. Aktuell überschlagen sich die Meldungen zu neuen Überwachungsplänen der verschiedensten Regierungen. Deshalb möchte ich einige dieser Pläne und die Hintergründe zu ihnen vorstellen und damit eine Art Fazit zum aktuellen Überwachungsstand liefern, auch wenn der Vortrag nicht erschöpfend alle aktuellen Maßnahmen betrachten kann. Hier geht es zu einem kleinen Teaser-Video zum Vortrag: https://video.dresden.network/w/7xaZpY5TVNVXfcSack7Prt Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://talks.datenspuren.de/ds25/talk/3KWCGS/…

Digital Euro - What the FAQ, ECB? (DS2025) 45:49

לפני 18 ימים45:49

45:49

The European Central Bank wants to create a Digital Euro. We take a critical look at its published FAQ and the current design. In its FAQ about the Digital Euro, the ECB provides answers to 20+ questions about the retail central bank digital currency (CDBC) project for a Digital Euro. In good old Frequently-Questioned-Answers style, we will confront those answers with our analysis of the utility, cost and technical feasibility of the current design. Among other things, we will cover the risks associated with central monitoring of all online transactions by the ECB, the plan to provide secure digital offline payments, and - on a meta level - the exclusionary process of the preliminary phases. This talk targets a general audience and will explain technical aspects where necessary.

Deine politische Initiative - aus dem Kopf, auf die Straße, in den StaDDrat (DS2025) 46:59

לפני 18 ימים46:59

46:59

Wie wird aus einer Idee eine politische Initiative? Und wie kann diese erfolgreich sein? In diesem Vortrag möchte ich allen, die sich mit ihrem Anliegen engagieren wollen oder dies bereits tun, Tipps und Hinweise geben, wie ihre Idee erfolgreich sein kann. Anhand von Praxisbeispielen möchte ich zeigen, wie man sich vernetzt, welche politischen Instrumente es gibt und wie man in der Öffentlichkeit und den politischen Gremien Dresdens Gehör findet. Seit 2011 bin ich in Dresden politisch und künstlerisch engagiert, seit 2019 Mitglied der Dresdner Piraten, seit 2021 arbeite ich hauptberuflich für die Piraten im Dresdner Stadtrat. In dieser Zeit hatte ich mit vielen politisch engagierten Menschen(gruppen) zu tun, die Dresden mit ihrer Idee ein Stück besser machen wollten.

How Russians deepen divisions in Ukrainian society (DS2025) 47:26

לפני 18 ימים47:26

47:26

How Russians use internal dividing lines that exist within nations to weaken them The Ukrainian nation is prone to internal conflicts due to its colonial past. Russians actively exploit this to weaken our country during the war. They can use similar, already proven techniques in other countries as well. Ukrainians joke that their internal online disputes on various issues should be included in UNESCO's cultural heritage. According to sociological research, the roots of this practice lie in the fact that until 1991, Ukrainians rarely had the opportunity to independently determine the fate of their own state. Our study mostly provided by NGO CAT-UA (Communication Analysis Team - Ukraine) focuses mainly on 2022, when Russia's full-scale invasion of Ukraine began. In the first months of this invasion, Ukrainians lived in unprecedented unity, but later returned to their usual quarrels. As a result, online discussions are ongoing, and Russians are taking advantage of this. Similar techniques may well be used in other countries where internal lines of division also exist. Our research into online content reveals which dividing lines Russians can see and which they cannot, where they are more successful and where they fall short. Similar techniques may well be used in other countries where internal lines of division also exist. A preliminary version of this study was presented at last year's event, but due to technical problems with the sound, the organizers asked us to update and re-present our data.

Integration 2.0: why the old system in Germany fails (DS2025) 43:33

לפני 18 ימים43:33

43:33

How the German integration system is delaying integration, and what the russian propaganda has to do with it Germany’s integration system was never built to help newcomers quickly find work. It was created decades ago for very different reasons — to slow things down, to keep migrants out of the labour market, to “protect” the status quo. That kind of system can’t suddenly start working in the opposite way. And today, with millions displaced by war, its limits are painfully clear. Long waiting times, endless paperwork, and wasted skills are not just personal tragedies — they are opportunities for Russian propaganda to exploit, sowing mistrust and division. Through real cases from Ukrainian refugees, we’ll show how these outdated structures affect lives every day and how, in the wrong hands, bureaucracy becomes a weapon Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://talks.datenspuren.de/ds25/talk/8BJF9W/…

CRA: Cybersicherheit in der Gesellschaft (DS2025) 44:16

Update zur Implementierung des Cyber Resilience Act (CRA). Der Cyber Resilience Act (CRA) wird derzeit implementiert und noch immer herrschen einige Unklarheiten in Hinblick auf seine Auswirkungen auf die Freie Software Landschaft. Insbesondere die Rolle der Stewards ist teilweise unklar. Der Vortrag wird den aktuellen Stand der Debatte beleuchten als auch Wege und Lösungen aufzeigen, wie mit den verschiedeneren Freie-Software-Akteuren umgegangen werden sollte. Zur Zeit ist unklar, inwiefern die verschiedenen Freie-Software-Anbieter vom Cyber Resilience Act (CRA) betroffen sind. Um Klarheit herzustellen Bedarf es Informationen, wer welche Rolle einnehmen wird und welche Aufgabe und Prozesse durchzuführen sind. Insbesondere die Rolle der Verwalter quelloffener Software (Open-Source Stewards) und Tätigkeiten bei Freier Software außerhalb des kommerziellen Interesses sind dabei von besonderer Bedeutung. Um sich den Fragen zu näheren haben wir eine Fragebogen an relevante Stakeholder ausgespielt, deren Ergebnisse wir vortragen und diskutieren wollen. Zudem wollen wir Wege aufzeigen, wie die Ergebnisse in den Implementierungsprozess des CRA einfließen können.

Building and maintaining large-scale data leak databases (DS2025) 17:00

לפני 18 ימים17:00

17:00

Technical and organizational insights into building and operating large-scale leak databases, using reveng.ee as a case study. Reveng.ee is a private database indexing extensive leaks of personal data from Russian sources, used by investigative journalists, military analysts, and law enforcement. Possible formats: - Workshop: guided exploration of how to search and work with leak data using the real interface — but this format has limited value because reveng.ee is a closed, paid service and will not be accessible to all participants; - Talk: an in-depth overview of where such data comes from, how it is processed and stored, search indexing for messy heterogeneous datasets, and operational considerations (security, legal, ethical). This would emphasize methodology and infrastructure rather than promoting or granting access to the actual platform. Either case will take about 20–25 minutes, followed by Q&A.
