This talk is about the bmc-toolbox, an open-source project that leverages the _Baseboard Management Controller_ (iLOs iDracs and similar) to help manage a large fleet (>50K) of bare metal servers at Booking.com [bmc-toolbox.github.io](https://bmc-toolbox.github.io/) Its goal is to provide vendor agnostic tooling to manage the lifecycle of bare metal servers, this talk describes the tools part of b...

Buck is an opensource build system. At Facebook, we’ve taught it to build container images that work with systemd. At Facebook we use an open-source build system called Buck. Buck is a build system designed to provide more strong guarantees of incremental builds, reproducibility, and dependency management. Open-source Buck can now be used to construct fully described and fully self-contained conta...

Despite of it's old age, ksh still remains one of the most popular shells. In 2013, David Korn and others who worked on ksh were laid off from AT&T Bell Labs. This lead to speculations of death of ksh. In 2017, Siteshwar Vashisht and Kurtis Rader resumed it's development on GitHub. This talk will be about what makes ksh so challenging to maintain and how new developers are trying to revive it. abo...

We'll be covering happenings, learnings and new challenges running and supporting systemd in production on the Facebook fleet throughout the past year. This talk is a followup to [State of systemd @ Facebook](https://cfp.all-systems-go.io/ASG2018/talk/192/) that was presented last year. We'll cover the latest developments, how we're leveraging new systemd features, the design of our CI/CD pipeline...

Most modern container image formats use tar-based linear archives to represent root filesystems, which results in many issues when using modern container images. In this talk, we will demonstrate a solution to this problem that we plan to propose for standardisation within the Open Container Initiative (code-named "OCIv2 images"). This talk is specific to the Open Container Initiative's image spec...

Due to virtual memory and optimistic caching strategies, true memory consumption of an application, and true utilization of a system's RAM, are mostly unknowns on modern operating systems. This has always made memory provisioning a tough and error-prone trial-and-error task, but it's aggravated with containerization, where the stated goal is thinner margins and higher resource efficiency. Senpai i...

The OSM-Community uses many different platforms and channels to discuss, organize and document internal issues. This talk provides an overview about the relevance and reach of these tools at local and international level and also locks into pros and cons of this strategy of communication in OSM. Creating a world map with as much detail as possible requires a lot of communication at local and inter...

Alternative Fakten? Wie konnte es passieren, dass Gerücht, Lüge, Fakt und Wahrheit ununterscheidbar wurden? Robert Feustel untersucht die Wissensgeschichte von der Industrialisierung bis zur Digitalisierung und zeigt, wie im sogenannten Informationszeitalter ebenjene „Information“ zum Heiligen Geist mutierte und den Unterschied zwischen Wahrheit und Lüge einebnet: Hauptsache sie zirkulieren möglic...

How useful are map features automatically extracted from street-level images? Can they be trusted? These are some of the questions we tried to answer through community campaigns and student-led research in 2019. We will share some of these lessons and elicit a broader discussion on the methods that can be used to turn automatically extracted features into useful OpenStreetMap data. In early 2019,...

Baden-Württemberg’s Ministry of Transport aims at developing regional mobility data towards an open and interoperable framework for new mobility solutions - as part of a sustainable traffic system, realising efficiency, climate protection and living quality. On the way there, fair chances for innovation are key: Not only for better results but also for a the involvement of most different societal...

What is an OSMF working group, what does the membership working group in particular do, and how can you improve the experience of an OSMF membership. The OSMF working groups are the main way in which the foundation supports OSM in specific areas. I am part of the membership working group since 2016. I will talk about working groups in general, what we do in the membership working group, and also t...

Testing the effectiveness of Kubernetes Network Policies can be done in different approaches. In this talk we will show you the benefits and drawbacks of different approaches and what solution we finally chose. Probably everybody who uses Kubernetes in a productive environment with multiple users possibly has looked at policies. Often the operators of the cluster(s) just trust the policies but in...

How to use plain OpenData and Imagery, to train, an accurate Deep Learning model, able to detect inconsistencies in OSM dataset, to spot it and to extract features. And make it works at scale, with OpenSource solution, named: RoboSat.pink. Deep Learning approaches already proves that they can be helpful for QA or MissingMap areas. RoboSat.pink as an efficient OpenSource Deep Learning toolbox dedic...

It’s been more than a year since we at Grab incorporated OpenStreetMap into our ecosystem and we have come a long way since then. This talk will focus on our learning journey, our tools, the challenges and our experiences working in the South East Asia region and the vibrant OpenStreetMap communities here. In the past few years, Grab as the biggest ride-sharing provider in Southeast Asia, is one o...

The Desktop GIS QGIS offers many ways to work with OpenStreetMap data. This presentation will give an overview on how you can use OpenStreetMap data with QGIS. The Desktop GIS QGIS (https://qgis.org) is Open Source software and an OSGeo project (https://osgeo.org). QGIS offers many possibilities to work with different sort of data - vector, raster & services. You can visualize, style, edit and pro...

oomd is a userspace out-of-memory killer. This talk covers past, present, and future development along with possible plans for systemd integration. Running out of memory on a host is a particularly nasty scenario. In the Linux kernel, if memory is being overcommitted, it results in the kernel out-of-memory (OOM) killer kicking in. Perhaps surprisingly, the kernel does not often handle this well. o...

We will present [Yomi](https://github.com/openSUSE/yomi), a new proposal for installing Linux using [SaltStack](https://github.com/saltstack/salt). This installer is designed to be used in heterogeneous clusters, where you need a bit of intelligence during the installation and be integrated as one more step in the provisioning process. [Yomi](https://github.com/openSUSE/yomi) is a new kind of inst...

Wer sich gegen Überwachung von Kommunikation wehren will, kann sich entweder kryptographischer oder steganographischer Methoden bedienen. Der Vortrag diskutiert die Möglichkeiten und Grenzen der Enttarnung steganographischer Kommunikation im Medium natürlicher Sprachen. Steganographische Kommunikation ist die Kunst des Versendens von Nachrichten über einen offenen Kanal, so dass niemand außer den...

Exploring the visualization of OSM data outside its digital form and how it can be applied to everyday object from book cover to wallpaper. This talk will discuss on how to elevate OSM data beyond maps, exploring its potential in data-as-decor on both public and private space. The talk will describe the tools and workflow on how to create these product as well as its strengths and weakness. When p...

Dieser Vortrag beschreibt die unterschiedlichen Phasen eines Hackerangriffs und wie man als gehackter professionell reagiert, neudeutsch "Incident Response" betreibt. about this event: https://datenspuren.de/2019/fahrplan/events/10393.html

Wir stellen unser Förderprogramm für Open-Source-Softwareentwicklung vor und laden zur Bewerbung für die aktuelle Förderrunde ein. Der Prototype Fund ist ein Förderprogramm für selbständige Software-Entwickler*innen und kleine Teams, die innovative Ideen prototypisch umsetzen wollen. Sie bekommen dafür fast 50.000 Euro Förderung vom Bundesministerium für Bildung und Forschung. Wir unterstützen die...

Traditionally processes are identified globally via process identifiers (PIDs). Due to how pid allocation works the kernel is free to recycle PIDs once a process has been reaped. As such, PIDs do not allow another process to maintain a private, stable reference on a process. On systems under pressure it is thus possible that a PID is recycled without other (non-parent) processes being aware of it....
