The boot loader specification defines a generic drop-in based solution for defining boot targets. sd-boot is a boot loader for UEFI systems, and included in the systemd source tree. In this talk we’ll have a closer look on the what, the why and the how of the specification and the boot loader. about this event: https://cfp.all-systems-go.io/ASG2019/talk/HFJMLU/

How to run clusters for GPU computing based blockchain hashing diskless on cost effective commodity hardware. Running the nodes of a cluster diskless is quite common in HPC environments. The challenges to run diskless in the context of blockchain hashing for cryptocurrencies are different. There are constraints like to run sufficiently on hundreds of machines with commodity 1 Gbit/s network hardware or the modest RAM size of 4 Gigabyte. This talk will provide insights in the technical approaches that made it possible to run GPU-clusters for blockchain hashing diskless and provide an outlook to other potential GPU-based use cases beyond blockchain hashing. I will discuss like how some early userspace trickery and state of the art RAM compression is used. How to handle the modest given RAM size and how a neat toolset based on container-runtimes helps to easily build boot images and plug-in packages. And how to use plug-in packages as an elegant way for adding further software like proprietary GPU drivers to the computing nodes of the clusters. about this event: https://cfp.all-systems-go.io/ASG2019/talk/XNU7NE/

Have you wondered if a certain dataset can be used for OSM? What does it mean for a license to be “compatible” with OSM and ODbL? This talk will give pointers on where to look for information, common compatibility issues, and best practices for presenting a license to LWG for help review. The talk would go over tips for mappers to help them think through potential license issues for imports. The tips would cover all the major steps for determining compatibility: identifying the data's license, check OSM-related history, identifying/resolving compatibility issues, and achieving community consensus. This talk will be useful for any mapper with compatibility questions or who is interested in importing open data into OSM. Outline: - Sources of information about the license - Website (page from which data is downloaded, about page, FAQ, TOS) - Accompanying file (e.g., README, LICENSE) - Terms, credits, etc. - Metadata - Information about licenses/dataset previously evaluated for use with OSM - Imports wiki page - License compatibility page - forums/lists - Common compatibility issues - Attribution - Use restrictions (e.g., noncommercial/personal/research) - Privacy - Sharealike - Revocability - Indemnity - Local laws - Things that are usually not a problem (disclaimer of warranty/accuracy, trademarks, governing law, ) - Making it easy for others to read a license - A note about translation - Link everything! - Include all information about the source - Where to obtain - Description of where/who the data is from - Include all information about the license - What the license is - Any info about permitted uses - Any prior OSM discussion - Flag common compatibility issues and why you think they are or are not issues - Quote the relevant sections of the license (include the section number!) - Explain your reasoning - If the license references other laws/regulations/terms, look them up and link to and quote from them. about this event: https://pretalx.com/sotm2019/talk/UN33XK/

<p>Not every data item in OpenStreetMap can have an immediate impact on the rendered map. But you can make every data item visible on a map and share the links or share the data, no matter how much the item is special interest. This is the purpose of Overpass API and Overpass Turbo. Our aim is to create special interest maps like this one for [historic street lamps](http://osmstreetlight.bplaced.net/#16/51.2339/6.7829), this one for [vehicle restrictions](http://maxheight.bplaced.net/overpass/map.html?zoom=14&lat=49.4&lon=8.68&layers=B0000000TFFTFFFFFFFF), or simply [all restaurants by cuisine](https://overpass-turbo.eu/s/I6z). An introduction to the Overpass API, to Overpass Turbo and the query language will be given. The aims are that the participants are afterwards able to filter for one for more tags, variants of tags, one or more keys, geographical regions, and combinations of such criteria. The Overpass API also supports to count objects, to dump them to GeoJSON, to retreive them in QGIS, in uMap, or a couple of [other downstream tools](https://dev.overpass-api.de/overpass-doc/en/targets/index.html). I will try my best to advance to these topics as well, but questions on the more basic issues have precedence. Thus the advanced topics are expected to rather go to an additional informal session if there are people interested in that. Please ensure that your are familar with the concepts of tags, nodes, ways, and relations, or read [an introduction here](https://dev.overpass-api.de/overpass-doc/en/preface/osm_data_model.html). You will benefit best from the workshop if you bring your own device with browser, internet access, and sufficiently large screen to view a map.</p> about this event: https://pretalx.com/sotm2019/talk/N9RCV8/

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 container images that work with systemd! I will show how we use this tool internally at Facebook and how it can be used externally (It’s open-source!) to build service containers for use by systemd. I will dive into the the details of how these builds are performed with systemd-nspawn, how we use the Buck system to define the systemd services and their dependencies, and how these images work at runtime. about this event: https://cfp.all-systems-go.io/ASG2019/talk/K7E7T7/

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, Mapillary began generating point data representing map features that have been recognized and extracted from images, including benches, fire hydrants, bike racks, and post boxes. We worked with various Mapillary communities and users to test the value of this new form of data. In this presentation, we’ll explore two campaigns. The first was the ***#mapillary2osm*** campaign which made point data available to six communities (Antwerp, Austin, Ballerup, Kyiv, Melbourne, São Paulo) in GeoJSON files and then encouraged map edits to turn each point into nodes on OpenStreetMap. Each location was given a 25 km^2 focus area and encouraged to add these points with the hashtag ***#mapillary2osm***, with the results being shared on a public leaderboard. The second was a project led by undergraduate students from the University of Washington’s Department of Geography. This particular project focused on a suburb of Portland, Oregon with the goal of validating and verifying Mapillary data in order to enrich OpenStreetMap. This involved measuring the difference between the OpenStreetMap data before and after the project and augmenting with Mapillary point data. We’ll conclude by looking at the longer term possibilities of editing OpenStreetMap with data derived using computer vision. about this event: https://pretalx.com/sotm2019/talk/KAPNKV/

Hikar is an OSM-based augmented reality navigation app for walkers and hikers, showing OSM ways overlaid on the camera feed of the device and, in the latest version, virtual signposts pointing the way to nearby points of interest. This technical talk will introduce Hikar, detail the many new developments since it was last presented at SOTM Birmingham 2013, and describe how it works in technical detail. Augmented reality (AR) has gained a great deal of media attention in recent years, helped in no small measure by the massive mainstream success of Pokemon Go. However, AR has a great deal of potential for real-world applications too, particularly for outdoor users, which has only partly been realised to date. A number of geospatial AR apps have been available for some years, including Layar and Wikitude, primarily focusing on points of interest (POIs), but many are proprietary and closed-source. One potential but little-explored application of AR is to provide navigation tools for hikers and other outdoor users, by overlaying paths and hiking trails on the camera feed of the device. An early version of the app discussed here, Hikar, was presented at SOTM Birmingham 2013, with the footpaths and trails sourced from OSM; however this version was difficult to use and was restricted in coverage to England and Wales. After a hiatus, development on Hikar has restarted in the past year, partly inspired by increased mainstream interest in AR and helped a great deal by the availability of global Terrarium elevation tiles and increasingly-affordable web hosting. The app (available on Google Play) now covers the whole of Europe and shows not only OSM ways but also virtual signposts, showing the distance and direction to nearby OSM POIs at path junctions, helping people navigate in the field. Virtual signposts support Greek and Cyrillic as well as Roman alphabets. The talk will include an in-depth technical discussion on how the virtual signposts feature has been implemented. Problems and issues with the app as it stands (such as the realism of the path and signpost placement, and inaccuracies with GPS and mapping data) will be discussed, along with strategies for resolving those problems, and future work (which may have already started by SOTM) will be outlined, including the use of computer vision and surface detection to more accurately place the virtual data within the real world. about this event: https://pretalx.com/sotm2019/talk/DETEML/

re:claimID is a decentralised service for self-sovereign personal data sharing. It allows users to reclaim their privacy and control over their digital identities and data while at the same time offering standard compliant protocol support through OpenID Connect. In this lecture, we present the motivation behind the technology and the technical foundations. <p> Today, users are often required to share personal data, like email addresses, to use services on the web. As part of normal service operation, such as notifications or billing, services require access to -- ideally fresh and correct -- user data. Sharing attributes in the Web today is often done via centralised service providers to reduce data redundancy and to give services access to current, up-to-date information even if the user is currently offline. Abuse of this power is theoretically limited by local laws and regulations. But, the past has shown that even well-meaning identity providers struggle to keep user data safe as they become major targets for hackers and nation state actors while striving for monetising anonymised statistics from these data. We advocate for a new, decentralised way for users to manage their identities for the following reasons: </p> <ul> <li> The current state of omniscient identity providers is a significant threat to the users' privacy.</li> <li>Users must completely trust the service provider with respect to protecting the integrity and confidentiality of their identity in their interest.</li> <li>The service provider itself is facing substantial liability risks given the responsibility of securely managing potentially sensitive personal data of millions of users.</li> </ul> <p>re:claimID is built as a service on top of the peer-to-peer framework <a href="https://gnunet.org">GNUnet</a>.<br/> It emerged from research conducted by the research group "Secure Applications and Services" at the <a href="https://www.aisec.fraunhofer.de/de/fields-of-expertise/projekte/reclaim.html">Fraunhofer AISEC</a> research institute.<br/> A scientific, peer-reviewed paper on the theoretical foundations of re:claimID was published at <a href="https://ieeexplore.ieee.org/document/8456003">TrustCom 2018</a> (<a href="https://arxiv.org/abs/1805.06253v1">Arxiv</a>).<br/> re:claimID is primarily developed in the <a href="https://git.gnunet.org/gnunet.git/tree/src/reclaim">GNUnet source tree</a> as Free Software.

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. about this event: https://cfp.all-systems-go.io/ASG2019/talk/CV9R3N/

CyclOSM is a new cycling render. It is free and aims at rendering new bicycle-specific features, in order to take into account the diversity of cycling practices. CyclOSM is a new cycling render. It is free and aims at rendering more features than OpenCycleMap, in order to take into account the diversity of cycling practices. For urban bikers (bike commuting), we decided to render all available types of cycle tracks and lanes, in a lateralized manner, as well as key POIs such as bicycle parkings, parkings shared with motorbikes, specific bike features (elevators / ramps), speed limitations, and surfaces of the highways to avoid paving stones. For bicycle tourers, we also rendered bicycle touring routes as well as a set of essential POIs (emergency services, shelters, tourism, shops) as wel las elevation data to help you design your bike journey. Building on the excellent quality of the OpenStreetMap data in Paris, we are also in touch with some local bicycle organizations to gather feedback and help them have a quick and detailed view of the current state of the cycling road infrastructure in the city. As such, a particular emphasis has been put on well rendering the quality of the infrastructures (clearly differentiating bidirectional cycle ways, dedicated lanes versus shared with public transport, etc) as well as some new elements which were not previously rendered: bike boxes and bumps. Designing a map render for every cyclist is a challenging task: bike infrastructures are usually parcimonious and very tightly bound to the road network, which makes bike-first visualizations not as readable as wished. There are also a wide variety of cyclist profiles, each requiring slightly different emphasis. CyclOSM is our attempt at tackling this challenge. In this talk, we will briefly sum up the main rendered features as well as discuss the design decisions and the difficulties of bicycle-oriented rendering. This talk will also provide a basic "getting started" summary, to help you start contributing and hacking this new render. A demo is already available at https://cyclosm.github.io/cyclosm-cartocss-style/example.html (limited to a few French cities at the moment, soon extended). The CyclOSM render is also available on the MapOSMatic instance https://maposmatic.osm-baustelle.de/.

This talk covers the ongoing effort about adding eBPF support to the GNU Toolchain. eBPF is a virtual machine running within the Linux kernel; initially intended for user-level packet capture and filtering, eBPF has since been generalized to also serve as a general-purpose infrastructure for non-networking purposes. This talk covers the ongoing effort about adding eBPF support to the GNU Toolchain. eBPF is a virtual machine running within the Linux kernel; initially intended for user-level packet capture and filtering, eBPF has since been generalized to also serve as a general-purpose infrastructure for non-networking purposes. Binutils support is already upstream [1]. This includes a CGEN cpu description, assembler, disassembler and linker. By the time of the conference a simulator will be available as well, along with GDB support. A GCC backend will be submitted for inclusion upstream before September. The first part of the talk will be a brief general description of the project, its components, what motivated us to start working on it, and an update on the project's status at the time of the conference. Then we will discuss the particular challenges of supporting a target like eBPF: On one hand, the kernel virtual machine has some unique characteristics that have a definitive impact on the tooling, like the in-kernel validator and the specialized contexts in which eBPF programs run. We will show how the tools can help improving the eBPF programmer's experience. On the other hand, the exact shape of compiled eBPF code is still subject to change, and is in fact rapidly changing and evolving. Initially quite simple in terms of toolchain needs (single compilation units, no linking) this is changing as more kernel systems are being changed/written to be based on eBPF, and as the in-kernel validator is becoming more and more sophisticated. Along with bigger and more complex programs comes the need for more abstraction, hence modularity and code reuse. Kernel hackers are already discussing about bpf-to-bpf calls, run-time linking, and so on. This increased level of ambition and sophistication imposes additional requirements on the tools. Finally, interoperability with clang/llvm (the other available toolchain supporting eBPF) will be also discussed, in the more general context of ABI and conventions for compiled eBPF, which are still to be (well) defined and documented.

Digitalisierung und Nachhaltigkeit sind die entscheidenden, existenziellen Herausforderungen des 21. Jahrhunderts. Obwohl beide Themen stark miteinander wechselwirken, werden sie bislang noch viel zu wenig gemeinsam gedacht und diskutiert. Die Bits&Bäume-Bewegung möchte das ändern! Gemeinsam wollen Menschen aus der Nachhaltigkeitsbewegung und der Tech-Szene aufzeigen, was Digitalisierung und Nachhaltigkeit verbindet und rufen dazu auf, die Grenzen der eigenen Filterblase zu erweitern. Die zentrale Frage lautet dabei: "Wie kann Digitalisierung vom Brandbeschleuniger sozialer und ökologischer Probleme zu einem Teil der Lösung werden?" Der Vortrag gibt - basierend auf den bisherigen Veranstaltungen - einen Überblick, was theoretisch getan werden müsste und stellt andererseits Maßnahmen zur Diskussion, die tatsächlich getan werden können. Die auf der 1. Bits-und-Bäume-Konferenz 2018 in Berlin erarbeiteten <a href="https://bits-und-baeume.org/forderungen/info/de">Forderungen</a> umfassen die Themenfelder Gemeinwohlorientierung, Demokratie, Datenschutz und Kontrolle von Monopolen, Bildung, Entwicklungs- und Handeslpolitk, IT-Sicherheit, sowie die Langlebigkeit von Software und Hardware. Zum Beispiel wird von Unternehmen gefordert, in Produktionsländern menschenrechtliche und ökologische Sorgfaltspflichten einzuhalten oder dass Software-Hersteller die Verantwortung für Sicherheitslücken in ihren Produkten tragen. Diese Forderungen sind einerseits also sehr naheliegend und in ihrer Plausibilität schon fast trivial. Andererseits verdeutlicht ein Abgleich mit der aktuellen Realität doch, wie groß die Missstände tatsächlich sind. Der Wert der elf Forderungen liegt darin, das große Ganze im Blick zu haben. Papier - auch digitales - ist aber geduldig und vom Aufschreiben der Forderungen allein werden diese nicht umgesetzt.<br><br> Die Herausforderung besteht nun darin, Maßnahmen auf individueller, zivilgesellschaftlicher, unternehmerischer und politischer Ebene zu finden und umzusetzen, welche die Digitalisierung im Sinne der B&B-Forderungen umgestalten - Schritt für Schritt und voraussichtlich gegen Widerstände und Beharrungskräfte. about this event: https://datenspuren.de/2019/fahrplan/events/10452.html

Lightning Talks ## OpenStreetMap intrinsic quality assessment using “Is OSM up-to-date?” web application <em>Marco Minghini and Francesco Frassinelli</em> <p>Approaches to analyze OpenStreetMap (OSM) intrinsically, i.e. based on the history of data, have become an established way to achieve a wide range of final goals, most importantly to study its quality. Started in 2017, “Is OSM up-to-date?” is an open source web application licensed under AGPL and mainly written in Python. It can be also run in the command line or inside a Docker container. The target beneficiaries of the software are OSM users and communities, who need to assess the quality of data in a given area to decide whether to use it or not as well as where mapping efforts should be best directed, and OSM researchers and scholars, who can use it as a tool to help in their OSM quality studies. The project has a dedicated wiki page (https://wiki.openstreetmap.org/wiki/Is_OSM_up-to-date), source code is hosted on GitHub (https://github.com/frafra/is-osm-uptodate) and a demo is available at https://is-osm-uptodate.frafra.eu. Using the OSM API, the web application generates history-based, quality-oriented visualizations of OSM nodes and ways having at least one tag for any rectangular user-selected region. Such visualizations (on top of a grayscale OSM basemap) are available for the following criteria: date of creation, date of last edit, number of versions, number of different contributors who edited that node or way, and frequency of update. When an OSM node or way is clicked, a popup shows its values for the previously mentioned criteria as well as the list of currently available tags and the links to the OSM iD editor (in edit mode on that node or way), history and details of that node or way (both linked to the OSM website). A number of additional features to further improve the analysis of quality is currently planned (see https://github.com/frafra/is-osm-uptodate/labels/enhancement).</p> ## Deriviste - Click and Go Photo Mapping <em>Christopher Beddow</em> <p>There are many OSM editing tools, but only one that allows the user to click inside a Mapillary image to add new data to the map. Richard Fairhurst's Deriviste tool was a quick experiment that proved this was possible, but it's important to ask more questions. How useful is the tool? How accurate and precise is it? How can it be improved?</p> ## Fifty states in 12 years and five minutes <em>Minh Nguyễn</em> <p>A whirlwind historical tour of the OpenStreetMap project in the United States.</p> ## "MAPAbabae": Using OSM as a Tool for Mapping with Women and For Women <em>Andi Tabinas, Arnalie Vicario</em> <p>We would like to share how we, as part of the Social Welfare and Development agency of the Philippines (DSWD), have utilized OSM to have a collaborative and gender-inclusive approach of mapping points of interests catering to women.</p> ## Reverse Geocoding Is Not Simple <em>Ilya Zverev</em> <p>Having seen a dozen of different geocoders, I did not expect to find myself writing another one. But here I am, tasked with making a reverse geocoder better than the industry-standard Nominatim. Turns out it is a fun and not so straightforward task. Let’s see what can go wrong.</p> about this event: https://pretalx.com/sotm2019/talk/BBRMPZ/

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 dedicated to GeoSpatial Imagery, can definitely help to quickly compare two datasets, as OSM and a coverage Imagery, and do it at scale. And spot where differences are significant enough, to value, that a human give them a look. This talk will focus on: - How to create an accurate trained model, for buildings and roads detection, from plain OpenData, without the needs to spend to much for hand-labeling features. - How to generate predictions faster, to lower the IT hardware footprint as much as we can. Point here, is to allow that anyone with a recent gamer video card, already can play with this tools. For information, RoboSat.pink main characteristics: - Provides several command line tools, you can combine together to build your own workflow - Follows geospatial standards to ease interoperability and data preparation - OSM data loader (using PyOsmium) - Build-in cutting edge Computer Vision model and loss implementations (and allows to replace by your owns) - Support either RGB or multibands imagery (as multispectral) - Allows Data Fusion - Rich and efficient Data Augmentation abilities (using Albumentations) - Static Web-UI tools to easily display, hilight or select results - High performances about this event: https://pretalx.com/sotm2019/talk/7ZXRXB/

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 of the biggest users and contributors of OpenStreetMap (OSM) in this region. We have put a great amount of effort into building a healthy ecosystem around it. We now have a better understanding of OpenStreetMap, mapping within its infrastructure, and how communities form one of its strongest pillars. We are excited to share how Grab started from scratch and gradually built a unified framework to manage OSM data as well as, more importantly, the velocity and data richness Grab has contributed back to OSM. We have worked closely with the different corporates, partners and the communities in the South East Asia region to support, build, guide, and empower ourselves and the community in contributing to improving OpenStreetMap. It has been a great learning journey so far with its share of peaks and valleys. Through this talk, we’d want to share our challenges and learnings from these experiences with the global OpenStreetMap community: - Grab’s ecosystem of managing OSM is a crowdsourcing system powered by data analysis, AI techniques, and other organic components - These include manual moderation and on the ground feedback from our well-trained map operations officers who are in every country striving to make the map as accurate as possible with local knowledge - Our experience in collaborating with the vibrant South East Asian Communities and different community partners like HOTOSM, through different programs and initiatives leading to a stronger community in this region - Collaborating with imagery partners like OpenStreetCam and Mapillary by contributing and making imagery available for cities like Singapore and Chiang Mai - Working along with the other corporates in this region as well as representing SEA on the OpenStreetMap Foundation advisory board - We will also share interesting findings of OSM in Southeast Asia and also shed light on how Grab has driven OSM to evolve here. about this event: https://pretalx.com/sotm2019/talk/PAG8CN/

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 talk about my experience in the latter. In the last year, we had quite a few new things going on like the fee-waiver program, we could improve our processes by using a support tracker and getting part of our procedures finally written down. And then there was the ever increasing wave of member sign ups before the elections, which this year raised the question of how we can protect the OSMF from being taken over by lots of new members from a particular interest group. There is still a lot of room for improvements of the experience for the OSMF members, and a few tasks that are still unresolved will be discussed in the last part of my presentation. And maybe you are interested in helping with one of them. We are all volunteers and it turns out some things need quite a bit of time and endurance to get done. We would be glad to get new participants to our group. about this event: https://pretalx.com/sotm2019/talk/FAGNLA/

Get to know the Board and the Working Groups. Together, we run the OSMF. Let's use the SotM to have a real face to face meeting. The public is invited to join the conversation too. SotM is about the community meeting the community. But we don't always seek out everyone we would like to talk to. So let's use this space to make sure as many members of the working groups and the board get to know each other as people and not just online text. All working group and board members are invited on the stage and can discuss anything. The public can also ask questions.

Come and learn about packit: tooling which enables you to integrate your upstream project into Fedora linux. Imagine a world where Linux distributions provide feedback about using your upstream project back to the project. So that when you are working on a change, you'll know right away: * if it builds or a project Z changed API again * if it works or that your change doesn't work with older systemd which this distro has * or if your change breaks components which depend on your project That's not all! If we have a service which can do all of this, why not propose a new upstream release automatically as a change to the linux distro once the release is done? Wouldn't it be awesome if upstream developers could control and track in which version their software is in Fedora 30? Sounds interesting? Please join us in this session and learn more about the packit tool and the packit service: tooling which makes your dream come true. about this event: https://cfp.all-systems-go.io/ASG2019/talk/US8XA9/

Bolsonaro is the most well know Face of brasilian Fascism and the so called “new right”. Although he is famous by his, lets say, bizzars declarations - what gave him the title of “The brasilian Trump” and a reputation of a crazy character - Bolsonaro is not just an excentric exception. On the contrary, he represents a strategy of Capitalism and a new fascist fog which is covering the planet. To understand it, we are going to review the political and historical roots of anti-comunism, the traumas of a military dictatorship, the effects of racist violence and the continuing struggles to land autonomy. Before the fog of fascism cover the complete Amazon Forest, we have to act! about this event: https://datenspuren.de/2019/fahrplan/events/10473.html

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 some cases it might be useful to control if the policies actually have taken action and often there are just to many Policies in the cluster setup to manually test them all (and obviously you don’t want to do this). Testing the effectiveness of the 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. Also we will show you some other tools and how they complement our solution. As a takeaway you will get an overview of different testing strategies for policies, as well as understanding challenges in testing policies in general and the Kubernetes ecosystem. We will get a feeling that it’s not always the best idea to just trust other plugins to implement the policies correctly. Our solution is open-sourced under https://github.com/inovex/illuminatio/ about this event: https://cfp.all-systems-go.io/ASG2019/talk/QXMUUW/

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 möglichst reibungslos und in Echtzeit. Schließlich gerät auch das Bild des Menschen in den Sog der Digitalisierung. Was unterscheidet das menschliche Denken vom prozessierenden Computer? Die neue Illusion vom allein Informationen verarbeitenden Menschen reduziere ihn auf sein Gehirn und übergehe Gefühle, Intuition, Vorstellungskraft und alles Seelische. Das gehe nicht ohne Kollateralschäden ab, stellt Robert Feustel fest. Bodo Morshäuser / Deutschlandfunk Kultur Mit popkulturellen Bezügen geht er dem Kult hinter dem „Konzept Information“ auf den Grund und analysiert die Unschärfe des Informationsbegriffs, der im Zuge der Digitalisierung laut Feustel eine neutrale und objektive Kontur bekam.

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 installer for the [open]SUSE family based on SaltStack and independent of AutoYaST. The goal of this project is to make the installation of Linux (currently openSUSE) when: * You have a cluster of heterogeneous nodes (different profiles of memory, storage, CPU and network configurations) * The installation needs to be unattended * The installer needs to make decisions based on local profiles and external data * The installation process needs to be integrated, as one step more, into a more complicated provisioning workflow. The dependencies of Yomi are minimal, as only Salt and a very few CLI tools are required, which make it ideal to be deployed a booted from PXE Boot. about this event: https://cfp.all-systems-go.io/ASG2019/talk/KDEYJZ/

Building forward from our work presented last year at State of the Map, we have created a system to assist mappers via machine learned models. In addition, we have built an automated ingestion framework for OSM data at scale that allows us to selectively update parts of the map instead of doing a full snapshot change. Building forward from our work on __Mobius Logical Changesets__ (presented last year at SotM US 2018), we have created an __automated ingestion and integrity framework__ for OSM data that allows us to __selectively__ update parts of the map instead of doing a full snapshot change all at once. Decomposing a large set of changes in this way gives us the flexibility to __rapidly ingest__ our own additions to the map, focus on __geographical areas of importance__ to downstream products, and allows us to __quickly apply hotfixes__ whenever egregious problems do arise. With millions of tiny changes happening every week, we have created a system that is built on __per-feature approval and preprocessing__, that allows us to ingest changes at scale, while creating rules to __automatically process logical changesets and enforce integrity constraints (e.g. anti-vandalism, anti-profanity etc.).__ Due to the contextual nature of some of the changes in OpenStreetMap, the system combines Human Approval, necessary for highly visible features such as names of large administrative areas, with __Automated AI/ML-based approval__: for example, using __computer vision techniques__ to reconcile newly created features against __satellite imagery ground truth__, or applying __NLP techniques__ to determine whether other user-visible string changes are sensible and valid. These components are combined to create a __continuous ingest-validate-deploy cycle__ for OSM map data. about this event: https://pretalx.com/sotm2019/talk/3WQKAX/

Over the last few months, we’ve been building an offline first field mapping tool for the OpenStreetMap ecosystem called Observe. Observe makes field surveying, and verification easy for mappers, and works on iOS and Android. My talk will cover how Observe integrates with mapping workflows and helps improve OSM data from the field. I'll also touch upon fundamentals of building Observe and our assumptions on field mapping. Field verification is an important part of keeping OSM data accurate. So far, field mapping exercises are largely manual, cumbersome, or requires internet connectivity. OpenStreetMap has an active mobile editing ecosystem, but they don't offer the same editing experience as iD for beginners. Most often mapping campaigns need an equally good tool that allows edits from the field to verify existing data and improve data quality. Observe is a cross-platform, offline-first field mapping tool for OpenStreetMap, perhaps the first of its kind. Our primary goal was to build an application that makes field observation easy, and provide comparable experience to iD on Android and iOS — with some success. Observe focuses on browsing OSM data, and allows users to add new points, or verify existing information. The edits made offline are stored on the phone, and uploaded when the mapper goes online. Observe is a product of several iterations of user research and a couple of years of conceptualization. The talk will: - introduce motivations behind building Observe - look at some specific use cases in campaign management - share internals of building the application - discuss challenges around offline editing and our approach to conflict resolution - gather feedback and launch a developer edition of the application about this event: https://pretalx.com/sotm2019/talk/39SBT8/

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 international level. There must be a place to discuss local mapping details and to organize mapping and hacking events. Additionally, a lot of international communication is needed in international OSM projects as well as in the OSMF and the Working Groups. Plus users and software developers also have their own discussion and documentation channels. For this purpose a lot of tools and platforms are established in OSM: Mailing lists, forums, wikis, websites, social media, etc. This variety of communication media is important and makes OpenStreetMap the colorful, open and diverse project it is today. But it also complicates the search on a particular topic and raises a number of questions: Where do I have to search to get up-to-date information? How can you distinguish between proposals, current and outdated content? What do you do if many sources contradict each other? How can knowledge best be passed on to subsequent OSM generations? This talk is intended to overview various communication platforms and their relevance and reach at local and international level. In addition, the advantages and disadvantages of the current strategy for communication and knowledge transfer will be discussed. about this event: https://pretalx.com/sotm2019/talk/R3BAWM/

This session provides an entertaining yet informative introduction into everything you need to know about OpenStreetMap. If you're new to OpenStreetMap, or maybe just know a little, then this session will fill you in on everything you need to know about OpenStreetMap. How did it start? How does it work? How can you contribute, and how can you use the data? What is this "Mapnik" think I keep hearing about and why do people always look at me funny when I say the license should be changed? OpenStreetMap is not just a database or a web site; it is a living and breathing project with a huge community and a 15-year history. Rather than just showing a sequence of slides, this session will be a tour de force presented by many different individuals, where entertaining dialogue is interspersed with hands-on short demonstrations and explanations. Attendees will leave this session with a good idea of how OSM works, of how they can contribute to OSM, and of how to use its wealth of data for making their own maps or just counting post boxes in their home town. But they will also see that OSM is very much about human beings. They will learn how to become part of the community of map makers, code writers, and general activists that make OSM into the great success it is today. about this event: https://pretalx.com/sotm2019/talk/NPYVSP/

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 people describe OSM data, usually it will revolve around its structures, type and geometry. And normally the data will be transform into maps, both in printed and digital format. Yet, we believe that it should not stay that way. Several efforts have been made to transform OSM data into everyday product, from simple things such as book cover, t-shirt design to wallpaper or wall paintings. Its open data license enables vast array of customization into product that some may consider as a work of art without constrained by cost and licensing. We will showcase what have been created by OSM community all around the world from OSM data in everyday objects and several products that we created ourselves for event merchandises (book cover, key chains, sticker, mouse pad, goody bag) and office decoration. For the product that we create we will explain the tools (software and hardware), options for media used and what is the workflow to create such product so that it will inspire the audience to create their own product for their area of interest as well as building geographic identity through design. We want to proliferate OSM data and transform its data beyond maps and explore its potential in non-conventional design. about this event: https://pretalx.com/sotm2019/talk/799WZF/

Currently everyone uses the same seccomp rules for running their containers. This tool allows us to generate seccomp rules based on what the container actually requires and allows us to lock down the container. We had a GSOC student this summer who instrumented podman to allow it to run containers and then genrate the seccomp rules for the container based on the syscalls that the container actually made. Once you have this newly generate seccomp file and are satisfied that you have thoroughly tested the container, you can run the container inproduction using the seccomp.json file. This talk will explain how the tool works and demonstrate it in action. about this event: https://cfp.all-systems-go.io/ASG2019/talk/ACEWHG/

Deep learning methods for feature extraction using computer vision are giving concrete results. This talk provides an overview of feature detection from satellite imagery and how machine learning can provide a seamless experience for mappers, allowing them to utilize their knowledge to enrich maps further. When using OpenStreetMap for disaster response and humanitarian action, time and data quality are critical. Automated tools around OpenStreetMap have revolutionized disaster response, allowing mappers to leverage their local knowledge to organize themselves in action and to contribute to highly relevant maps. Over the last year, Tasking Manager team at HOT conceptualized an initiative to test using data derived using machine learning models to improve task creation, quality of edits and overall experience for mappers. Within Tasking Manager Working Groups we are collaborating between different actors to test concepts directly applied to two countries: Tanzania and Uganda. Two tools in pilot phase to assist mappers are around 1) Task Creation and facilitation: identify areas that need most work and/ or need an experienced mapper based on task complexity and gap analysis 2) Assisted Mapping: leverage machines to do the heavy lifting around digitizing features, such as buildings and roads, one by one and allowing mappers to focus on their essential craft of mapping. In this talk the presenters will share their findings, learning and existing challenges with the technology. about this event: https://pretalx.com/sotm2019/talk/DPGWFB/

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 specification, but the same techniques could be applied to other systems (though we'd obviously recommend using OCI). In order to avoid the [numerous issues with tar archives](https://www.cyphar.com/blog/post/ociv2-images-i-tar) it is necessary to come up with a different format. In addition, layer representations result in needless wasted space for storage of files which are no longer relevant to running containers. Massive amounts of duplication are also rampant within OCI images because tar archives are completely opaque to OCI's content-addressable store. Luckily the problem of representing a container root filesystem for distribution is very similar to existing problems within backup systems, and we can take advantage of prior art such as [restic](https://restic.net/) to show us how we can get significant space-savings and possibly efficiency savings. However, we also must ensure that the runtime cost of using this new system is equivalent to existing container images. Container images are efficient at runtime because they map directly to how overlay filesystems represent change-sets as layers, but with some tricks it is possible for us to obtain most of the improvements we also gained in distribution with de-duplication. Our proposed solution to all of these problems will be laid out, with opportunities for feedback and discussion. about this event: https://cfp.all-systems-go.io/ASG2019/talk/VMTEPT/

Lessons learned operating thousands of stateful production clusters on top of Fedora and systemd-nspawn. Aiven is a cloud data platform operating thousands of production clusters on top of different cloud infrastructure providers (e.g. AWS, GCP). We offer the latest open source database & streaming engines to our users around the world, and implement most of our platform using the latest open source software including Fedora and systemd-nspawn. We wanted to base our platform on a fast moving Linux distribution like Fedora to gain quick access to new technology and avoid having to backport a lot of things. Fast moving distributions are typically not supported for a long time, but implementing an immutable infrastructure where deployed machines are not touched afterwards makes it possible to use them in production. In this talk we’ll share the details of our architecture and the lessons we’ve learned as well as problems we’ve faced over the years operating hundreds of thousands of virtual machines and containers with it on top of six different public clouds. about this event: https://cfp.all-systems-go.io/ASG2019/talk/RLCDFS/

During development and testing it is often needed to test different kernels or run various sets of unit tests quickly. With lrun it is possible to do exactly that. It utilizes existing technology including UML, KVM and Namespaces to facility different environments. It has been in active use for testing Bluetooth and Wi-Fi features on Linux and can be easily extended to other technologies in the future. This presentation will introduce lrun and its design. It will also show demos of its current use cases. about this event: https://cfp.all-systems-go.io/ASG2019/talk/N8YRKX/
