Es haben sich nicht nur tolle Projekte (weiter)entwickelt, wir haben auch einen tiefen Einblick in die Entwicklung von Open Source Software bekommen und dabei einige „lessons learned“ gesammelt. Diese hilfreichen Erfahrungen für die Planung und Durchführung von solchen Projekten wollen wir gerne teilen.\n\nDer Prototype Fund unterstützt seit 2016 Open Source Software EntwicklerInnen, die in den Bereichen Civic Tech, Data Literacy, Datensicherheit und Infrastruktur neue Projekte ausprobieren oder bestehende ausbauen wollen. Was dabei allen gemein ist: Es dauert immer länger, als man denkt. Diversität entscheidet über den Erfolg eines Projekts. Für Coachings ist es nie zu früh. Diese und andere Learnings hatten viele Projekte während sie vom Prototype Fund gefördert wurden. Auch auf Seiten des Prototype Fund Teams haben wir nach dem Lesen vieler Bewerbungen wiederkehrende Fehler und erfolgsentscheidende Punkte identifiziert: Projekte wollen oft zu viel für sechs Monate coden, trotz aller technischen Details muss der Sinn und Zweck des Vorhabens verständlich sein, was ist der Mehrwert des Codes und ist er auch für andere nutzbar, kennt das Projekt seine Community und bindet es sie ein? In diesem Talk wollen wir mit euch die Learnings der ersten drei Runden Prototype Fund Projekte teilen und euch einige Tipps und Tricks für eine gute Bewerbung mitgeben.","original_language":"deu","persons":["Adriana"],"tags":["froscon2018","2188","other"],"view_count":84,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2023-06-19T17:15:03.383+02:00","length":2979,"duration":2979,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2188-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2188-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/98f55e6b-2b4a-4d8d-bfd8-0e7a561119ae-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/98f55e6b-2b4a-4d8d-bfd8-0e7a561119ae-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2188-how_to_prototype_fund","url":"https://api.media.ccc.de/public/events/98f55e6b-2b4a-4d8d-bfd8-0e7a561119ae","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":3},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":1},{"event_id":5744,"event_guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","weight":1},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":3},{"event_id":5752,"event_guid":"75d71314-74b8-43c4-893f-c1ddb0cc050b","weight":2},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":2},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":1},{"event_id":5762,"event_guid":"ae6e36cb-713c-4b73-99ac-f1b95f910e32","weight":1},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":4},{"event_id":5771,"event_guid":"226378b4-80f1-4bd5-bf02-49ec5a3ac34c","weight":1},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":3},{"event_id":5775,"event_guid":"8c0b8e5b-7e38-486a-bd97-5329857ffae8","weight":3},{"event_id":5776,"event_guid":"fd9ddda5-892f-4f55-ad36-b47044986bb3","weight":1},{"event_id":5777,"event_guid":"26bca6f5-82ca-47e3-b022-b0d1228f2563","weight":2},{"event_id":5778,"event_guid":"c18d8138-d063-4f42-a5ba-d48c9e617714","weight":1},{"event_id":5779,"event_guid":"887c6067-774c-4ec3-a3bd-b888e137eec0","weight":2},{"event_id":5780,"event_guid":"62e8df5f-cd0b-4606-8d61-18b274e1d048","weight":2},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":1},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":4},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":2},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":1},{"event_id":5808,"event_guid":"daa949b6-e0b2-4f4d-bd98-a9241f6d09c4","weight":4},{"event_id":5809,"event_guid":"68e5d6b9-b0cb-4317-b724-5f45145c7eba","weight":1},{"event_id":5822,"event_guid":"92d1bc03-3224-4dc6-be3a-691e96d641fb","weight":1},{"event_id":5825,"event_guid":"d535dfae-c59a-4a72-9d86-94e3ce66e549","weight":2},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":3}]},{"guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","title":"Puppet, Salt oder Ansible – welches Tool ist das Richtige?","subtitle":null,"slug":"froscon2018-2160-puppet_salt_oder_ansible_welches_tool_ist_das_richtige","link":"https://programm.froscon.de/2018/events/2160.html","description":"Client-basiertes Configuration-Management oder ssh-basierte Configurationorchestration?

Es wird gezeigt, wie Blockchains als \"digital trust\" ohne Open Source undenkbar sind und welche weiteren Entwicklungen absehbar oder wünschenswert sind.\n\nEin Ethereum/Smart-Contract/Solidity-Tutorial also, mit viel Blick über den Tellerrand des Themas.\n\nEine Einführung zu Blockchains im Allgemeinen (wie z. B. Bitcoin) wird zu Beginn des Vortrags in Kurzfassung gegeben.

Docker [2] provides a free and open-source platform for building and running container images in a controlled and isolated environment. Kubernetes [3], which is also free and open-source, provides an orchestration system which enables automated deployment and management of containerized applications. Around Docker and Kubernetes there exists a vast ecosystem of tools and services. At the Department of Computer Science 4 of the University of Bonn we recently started using these technologies in both science projects and teaching. With this talk we intend to share our experiences with other people which might use container technology in similar use cases.\n\nOur presentation will be split in five sections, which will cover the following topics:\n\n* Use cases: We will give a general overview about which applications for container technology exist within a university. Specifically, we intend to highlight the similarities and differences to normal software development, DevOps, etc.\n* Science vs. Teaching: Container technology can be used in both science and teaching. However, the intended goals and also the needs and requirements of both areas may differ significantly.\n• Implementation and Experiences: Based on the ideas and considerations described above we implemented a Kubernetes cluster in our department. We will give a detailed description of the cluster architecture and our experiences so far.\n• Problems and ”Lessons learned”: As for every new project there are things which turned out to be more difficult than expected. We will talk about these problems and what we learned from that.\n• Recommendations and Outlook: Concluding our presentation, we will give some recommendations to other people who intend to implement container technology in a similar scenario. We will also outline some of our plans for the future.","original_language":"eng","persons":["Fabian Marquardt"],"tags":["froscon2018","2264","FrOSCon meets Science"],"view_count":223,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-04-13T20:30:03.054+02:00","length":3482,"duration":3482,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2264-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2264-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/fd9ddda5-892f-4f55-ad36-b47044986bb3-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/fd9ddda5-892f-4f55-ad36-b47044986bb3-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2264-docker_and_kubernetes_at_the_university_using_container_technology_for_science_and_teaching","url":"https://api.media.ccc.de/public/events/fd9ddda5-892f-4f55-ad36-b47044986bb3","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":4420,"event_guid":"99398913-ee5b-482b-bc03-918fcc6285ac","weight":9},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":11},{"event_id":5737,"event_guid":"6c23d096-973d-40f5-bf72-3c9c7f2cd58a","weight":2},{"event_id":5744,"event_guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","weight":7},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":9},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":7},{"event_id":5757,"event_guid":"fbec0a5a-7a3b-485d-8c50-e732dcea014f","weight":7},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":9},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":3},{"event_id":5775,"event_guid":"8c0b8e5b-7e38-486a-bd97-5329857ffae8","weight":2},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":21},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":4},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":9},{"event_id":5812,"event_guid":"da6793a9-767e-462a-84cf-e35f7a585b24","weight":7},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":8},{"event_id":5822,"event_guid":"92d1bc03-3224-4dc6-be3a-691e96d641fb","weight":5},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":11}]},{"guid":"fbec0a5a-7a3b-485d-8c50-e732dcea014f","title":"Nebenläufige reaktive Programmierung mit Go","subtitle":"Reaktives programmieren ohne Frameworks","slug":"froscon2018-2121-nebenlaufige_reaktive_programmierung_mit_go","link":"https://programm.froscon.de/2018/events/2121.html","description":"Je komplexer Web-Applikationen werden, desto wichtiger werden reaktive nicht-blockierende Backends.

We show and explain other unique features as well, arising from a well documented set of requirements.\n \nProceeding, we consider attack vectors including decapsulation, electron and voltage contrast microscopy, side channel glitching and correlation power analysis, as well as potting compound removal and run of the mill hypodermic needle tapping of serial bus lanes.\n\nContinuing with hardware design, we review the workflow designers and layout engineers follow while creating an experimental circuit. We reflect on the six month project and it's unique distribution and test process as well as strong community ties supported by the communication and documentation we've chosen to emphasize. Lastly, we explain the production of a hardware wallet device from print to assembly and even demonstrate a rapid prototyping hardware run to produce a single board (components and all)

Dabei wird der komplette Lebenszyklus vom Erstellen über das Starten und Ändern der VM bis zur Balancierung des Clusters mit einheitlichen Kommandozeilen-Programmen gesteuert. Außerdem wird eine API bereitgestellt, mit der alle weiteren vom Nutzer benötigten Funktionen automatisiert werden können.\n\nDie Enwicklung durch Google wirkte sehr strukturiert: Es wurde erst nachgedacht, in öffentlichen Design-Dokumenten festgehalten und verfeinert, dann programmiert. \nDieses Vorgehen haben wir bei der Entscheidung und Benutzung sehr geschätzt, da dies Stabilität ausstrahlt und die Konsistenz in der Bedienung unterstreicht.\nSämtliche Funktionalitäten sind durch- und zu Ende gedacht, allerdings ist uns dabei auch aufgefallen dass ein Design-Dokument noch keine Implementierung ist.\nWir erzählen von unseren Schwierigkeiten, unserer Lernkurve und dem Weg Ganeti für unseren Anwendungszweck einzurichten. \n\nGoogle hat leider die Entwicklung, kurz nachdem wir angefangen haben, Ganeti zu benutzen, mehr oder wengier eingestellt. Im Moment wird durch verschiedene Akteure und Nutzer versucht, eine Community aufzubauen, die Ganeti bzw. einen Fork weiter entwickelt. Wir werfen einen Blick auf den aktuellen Stand, in der Hoffnung, dass es bald Dienstag wird.","original_language":"deu","persons":["Hinrikus Wolf","Lars Beckers"],"tags":["froscon2018","2234","System Administration"],"view_count":391,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-05-17T02:00:04.477+02:00","length":2825,"duration":2825,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2234-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2234-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/1963b747-4067-4b34-9c45-debd2f020fef-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/1963b747-4067-4b34-9c45-debd2f020fef-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2234-ganeti_ein_humoristischer_erfahrungsbericht","url":"https://api.media.ccc.de/public/events/1963b747-4067-4b34-9c45-debd2f020fef","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":21},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":22},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":20},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":29},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":22},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":19},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":18},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":18},{"event_id":5769,"event_guid":"76ad2dd9-6054-44b4-a969-eb8f1bf87d62","weight":22},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":21},{"event_id":5775,"event_guid":"8c0b8e5b-7e38-486a-bd97-5329857ffae8","weight":3},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":19},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":27},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":22},{"event_id":5793,"event_guid":"05d2f707-19a8-491d-a375-13280c771034","weight":3},{"event_id":5795,"event_guid":"d3821dc9-94af-438a-af6a-d4f79df43a2f","weight":7},{"event_id":5811,"event_guid":"b9affdeb-41c2-4322-8a5a-1c7676372ea9","weight":11},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":23},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":43}]},{"guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","title":"Open Source darf auch was kosten","subtitle":"Vom Hobby Projekt zum Beruf","slug":"froscon2018-2219-open_source_darf_auch_was_kosten","link":"https://programm.froscon.de/2018/events/2219.html","description":"Den Lebensunterhalt mit der Arbeit am eigenen Open Source Projekt verdienen; Seit ein paar Jahren gelingt mir das und nun möchte ich die damit gemachten Erfahrungen weiter geben.\n\nSeit Anfang 2014 arbeite ich in Vollzeit an dem Open Source Instant Messenger Conversations.

This talk dives into the pipeline we've put together at REWE Digital to cater our own developers writing microservices in Java, Scala, Go and node.js.\n\nAfter the first huge frenzy about enabling everyone to build software and deploy it in a container, so that they decide what's in the container, you soon realize that you solved the \"shipping an application\" issue. But now you've to consider how to update your docker base images. Wait, you've a base image right? Or did every team just pick one from Docker Hub on their own?\nOnce you've sorted that out the inevitable question is: how do we regularly update those base images?\nThis talk dives into the issues we've found and what our current base image build process and lifecycle looks like. It's the ugly truth about chaining Jenkins, docker and container-diff all together and why we moved from Alpine to Debian based images. \n","original_language":"deu","persons":["Sven Höxter"],"tags":["froscon2018","2187","Cloud"],"view_count":472,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-03-30T11:45:03.131+02:00","length":3482,"duration":3482,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2187-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2187-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/065821fd-67da-4565-a380-a6a9d403416e-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/065821fd-67da-4565-a380-a6a9d403416e-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2187-herding_docker_images","url":"https://api.media.ccc.de/public/events/065821fd-67da-4565-a380-a6a9d403416e","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":2735,"event_guid":"5c0323b6-c538-4fb6-8d70-d08def6bf865","weight":1},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":18},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":15},{"event_id":5746,"event_guid":"ad920111-8443-4cde-9184-c94aa42a41db","weight":19},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":17},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":16},{"event_id":5755,"event_guid":"8ab1c7ea-00ee-4f1a-8e5a-7b60ec80408f","weight":4},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":27},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":12},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":12},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":7},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":12},{"event_id":5776,"event_guid":"fd9ddda5-892f-4f55-ad36-b47044986bb3","weight":21},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":9},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":16},{"event_id":5806,"event_guid":"7d5ff8e1-f69b-493a-a5b5-e464cf2e5b74","weight":4},{"event_id":5809,"event_guid":"68e5d6b9-b0cb-4317-b724-5f45145c7eba","weight":13},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":15},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":24}]},{"guid":"887c6067-774c-4ec3-a3bd-b888e137eec0","title":"State of the Union 2018","subtitle":"Das Open Source/Free Software/Technologiejahr 2018","slug":"froscon2018-2210-state_of_the_union_2018","link":"https://programm.froscon.de/2018/events/2210.html","description":"20 Jahre alt ist der Begriff \"Open Source\" dieses Jahr geworden.

Dabei werden Cluster als native OpenStack-Ressourcen angeboten. Ein Cluster besteht aus virtuellen Maschinen oder Baremetal-Servern, auf denen eine Cluster Orchestration Engine wie Kubernetes provisioniert wird, sowie Netzwerk-Ressourcen zur Anbindung dieser Server an die Außenwelt. Parameter wie zu verwendene COE, Images, Keypairs, etc werden über sogenannte Cluster Templates definiert. Die Integration zwischen COE und OpenStack geschieht über sogenannte Cluster-Treiber, wobei ein Cluster-Treiber jeweils für eine bestimmte COE auf einer bestimmten Disitribution zuständig ist.\nDiese Cluster-Treiber bestehen aus Python-Code, Heat-Templates, Skripten, Images und Dokumenten und beinhalten Informationen darüber, wie ein Cluster erzeugt wird, skaliert, welche Glance-Images verwendet werden, und kümmern sich auch um das Installieren und Konfigurieren weiterer Dienste, das Hinzufügen von SSL-Zertifikaten sowie das Ausführen von weiterem Code.\nIn diesem Talk werden wir zeigen, wie sich genau diese Cluster-Treiber auf die eigenen Bedürfnisse anpassen lassen.","original_language":"deu","persons":["David Rabel"],"tags":["froscon2018","2180","Cloud"],"view_count":193,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-02-17T15:45:05.699+01:00","length":3309,"duration":3309,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2180-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2180-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/da6793a9-767e-462a-84cf-e35f7a585b24-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/da6793a9-767e-462a-84cf-e35f7a585b24-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2180-container-orchestrierung_in_der_cloud_fur_profis","url":"https://api.media.ccc.de/public/events/da6793a9-767e-462a-84cf-e35f7a585b24","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":4},{"event_id":5753,"event_guid":"0f675194-51f2-4165-9c6c-9b5653bc52e6","weight":3},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":3},{"event_id":5757,"event_guid":"fbec0a5a-7a3b-485d-8c50-e732dcea014f","weight":3},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":4},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":3},{"event_id":5776,"event_guid":"fd9ddda5-892f-4f55-ad36-b47044986bb3","weight":7},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":7},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":1},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":3},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":4},{"event_id":5810,"event_guid":"291fe17d-80ca-46a9-9978-c61509a4f9c9","weight":4},{"event_id":5811,"event_guid":"b9affdeb-41c2-4322-8a5a-1c7676372ea9","weight":2},{"event_id":5814,"event_guid":"35fdf9d0-bb63-484e-9309-cc2a07073ca7","weight":4},{"event_id":5816,"event_guid":"4a6584de-59fd-405e-be42-ce295cc516f2","weight":6},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":5},{"event_id":5822,"event_guid":"92d1bc03-3224-4dc6-be3a-691e96d641fb","weight":3},{"event_id":5825,"event_guid":"d535dfae-c59a-4a72-9d86-94e3ce66e549","weight":1},{"event_id":5828,"event_guid":"b36d437f-7643-422d-b429-316a83826304","weight":3},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":3}]},{"guid":"61fc8330-6177-45d9-b644-18c0420422f0","title":"das richtet sich von selber","subtitle":"Neuigkeiten und Erfahrungen mit Rudder als Config Management tool","slug":"froscon2018-2239-das_richtet_sich_von_selber","link":"https://programm.froscon.de/2018/events/2239.html","description":"Wie sieht die tägliche Arbeit mit einem GUI-orientierten Config Management aus?

And for good reason. Test automation (regression testing) is essentially not working—many teams are discarding efforts and people talk about the ROI of deleting tests. Especially on the UI-level, tests tend to be brittle and incomplete, yet a huge effort to create and maintain—reflected in the famous test pyramid. This is a stark contrast to current trend topics, like CI/CD, DevOps and shift-left. So how can we solve that problem?\n\nAssertions are the go-to checking mechanism in unit tests. However, when applied to testing interfaces, specifically GUIs, I consider them to be toxic. It is hard, but still feasible, to achieve a certain level of separation on the unit level. On the interface level, where integration is inevitable, it is outright impossible. And practice shows exactly that. \n\nBut there are alternatives. From ApprovalTests to TextTest to various pixel-comparison tools, Golden Master Testing is a viable option. I give a short overview about them, together with some practical example when to apply what.","original_language":"eng","persons":["Jeremias Rößler"],"tags":["froscon2018","2235","Development"],"view_count":83,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2024-03-09T16:15:02.688+01:00","length":3125,"duration":3125,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2235-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2235-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/8587bf27-b64f-4161-86a5-f77ee1735b3f-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/8587bf27-b64f-4161-86a5-f77ee1735b3f-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2235-assertions_considered_harmful","url":"https://api.media.ccc.de/public/events/8587bf27-b64f-4161-86a5-f77ee1735b3f","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":2},{"event_id":5735,"event_guid":"d494138e-2442-4b08-b06b-43e1aa444701","weight":1},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":3},{"event_id":5743,"event_guid":"98f59651-b6ed-4428-9d9d-355873a8901d","weight":2},{"event_id":5744,"event_guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","weight":2},{"event_id":5748,"event_guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","weight":3},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":2},{"event_id":5752,"event_guid":"75d71314-74b8-43c4-893f-c1ddb0cc050b","weight":2},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":2},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":2},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":3},{"event_id":5771,"event_guid":"226378b4-80f1-4bd5-bf02-49ec5a3ac34c","weight":2},{"event_id":5774,"event_guid":"191e9835-4941-4f73-9c80-d453d684bb03","weight":2},{"event_id":5781,"event_guid":"60b11faf-4afc-4c25-bae5-a59d48bda32a","weight":2},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":2},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":2},{"event_id":5790,"event_guid":"f9c7f1a4-a696-4559-9d65-52e770591c38","weight":2},{"event_id":5791,"event_guid":"9144aaee-4cb6-4497-89d9-acca7da85730","weight":3},{"event_id":5811,"event_guid":"b9affdeb-41c2-4322-8a5a-1c7676372ea9","weight":1},{"event_id":5814,"event_guid":"35fdf9d0-bb63-484e-9309-cc2a07073ca7","weight":3},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":2},{"event_id":5828,"event_guid":"b36d437f-7643-422d-b429-316a83826304","weight":2},{"event_id":5829,"event_guid":"9b34e4d2-533b-44ac-94c9-d53a70bc11a8","weight":2},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":4},{"event_id":5831,"event_guid":"5fa9fb17-3bb5-43c2-9ef9-3ed9db1c957a","weight":2}]},{"guid":"62e8df5f-cd0b-4606-8d61-18b274e1d048","title":"Beyond WHERE and GROUP BY","subtitle":"SQL after 1986","slug":"froscon2018-2179-beyond_where_and_group_by","link":"https://programm.froscon.de/2018/events/2179.html","description":"We've been writing SQL queries with WHERE, GROUP BY, ORDER BY, HAVING for decades.

With the advent of KDE5 and Wayland, which are nowadays standard part of every Linux distribution, accessing X11 directly is no longer possible and porting the old code to Qt5/KDE5 was not really a viable way forward. \n\nSo we started over from scratch and took the path LibreOffice's Gtk3 plugin has trailblazed: for rendering, we used headless backend in combination with cairo. We enhanced it with Qt5 native widget styles, added native Qt5 menus, integrated Plasma 5 file picker, shook and stirred well.\n\nCome and see what came out of that.\n","original_language":"eng","persons":["Katarina Bubli Behrens"],"tags":["froscon2018","2229","There’s a Tux in your window"],"view_count":216,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2024-07-07T22:45:04.708+02:00","length":2100,"duration":2100,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2229-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2229-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/0f675194-51f2-4165-9c6c-9b5653bc52e6-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/0f675194-51f2-4165-9c6c-9b5653bc52e6-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2229-look_it_s_libreoffice_on_kde_plasma","url":"https://api.media.ccc.de/public/events/0f675194-51f2-4165-9c6c-9b5653bc52e6","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":15},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":8},{"event_id":5743,"event_guid":"98f59651-b6ed-4428-9d9d-355873a8901d","weight":7},{"event_id":5744,"event_guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","weight":6},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":8},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":10},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":9},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":10},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":10},{"event_id":5767,"event_guid":"dbb0c6bc-d14f-4d9b-9c9e-f66fa0143721","weight":5},{"event_id":5778,"event_guid":"c18d8138-d063-4f42-a5ba-d48c9e617714","weight":7},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":7},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":10},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":3},{"event_id":5823,"event_guid":"7c5c320f-da0f-466f-b312-49cef37d862c","weight":9},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":7}]},{"guid":"226378b4-80f1-4bd5-bf02-49ec5a3ac34c","title":"Open Source in the WSN Research","subtitle":"Experiences made with free and open source software in scientific research.","slug":"froscon2018-2265-open_source_in_the_wsn_research","link":"https://programm.froscon.de/2018/events/2265.html","description":"This is to share experience made with open source software (OSS) in the public research with the community. After introducing some background and pinning down the author’s research area, the pros and cons for publishing OSS are discussed from the research perspective. Then, several case studies are given to show how OSS and research work may influence each other. The emphasis is on checking the original motivation and the spirit of OSS back with the reality. Finally, future potentials of research OSS are outlined. The talk concludes with summarizing the experiences wrapping up the presented results.\n\nIntroduction The IHP is a publicly funded research institute in the fields of silicon–based systems, highest–frequency integrated circuits, and technologies for wireless and broadband communication... [explicated in full paper] Among two other fields of applications, the Wireless Systems department conducts research and system–level development in\nthe area of wireless sensor networks (WSN) and middleware platforms. For many years, the author contributed to the evolution of mobile, context–aware software, recently with a focus on health care applications. Technically, the author is dedicated to software development for tiny, resource–constrained sensory devices.\nWhy open source? The use of open source software has never been doubted. When compared to closed–source software, OSS has its major advantage in lower total costs of ownership (TCO), which includes direct licensing costs, but also support and lifetime maintenance. Being under a steady public review adds the aspect of trust, which is especially important for colleagues dedicated to the implementation of cryptographic algorithms. However, publishing results as open source is different from just using OSS. For a research institution, classic ways of disseminating results include scientific publication, patents and spin–offs. Among other parameters, these quantities make up the metric used to evaluate the research performance of academic institutions across the world. Still, it’s beneficial to accompany the own exploitaton strategy with an OSS option for the following reasons [more given in full paper]:\n• OSS publication increases visibility.\n• Providing sources to the public allows for qualified criticism and feed back.\n• The result was created from tax–payer’s money, it’s an obvious option to return it to the public. \nCounter–arguments such as the following are well–known and will be discussed in more detail [more given in full paper]: \n• OSS publication gives away valuable results decreasing our third–party income.\n• Publishing open source is risky / not allowed for legal reasons.\n• We didn’t do that ever before!\nCase studies Allthough deployed in the author’s environment, the usefulness of general purpose OSS such as Typo3 or Ubuntu is not specific to research and thus, will not be addressed in this talk. ocapi The ocapi project is a low–level driver library for TI’s MSP430 microcontroller. It is entirely written in C and targets both, the proprietary TI–compiler as well as the open source GCC compiler. Functionally, it provides a high–level API to control MSP430 built–in peripherals. It is online since 2012 and has been the software foundation for a couple of wireless sensor networks projects. Allthough downloaded 20 to 50 times annually, there is no third party feedback for ocapi, up to now. GCC for MSP430 The GNU Compiler Collection for TI’s MSP430 microcontroller was heavily used when developing software for wireless sensor nodes. During a long–term experience, the author observed the compiler’s evolution from a hard–to–use helper tool up to a community–driven full–featured software development suite. In the early stage, the author contributed to its development by filing bugs and testing patches. Meanwhile, this GCC was maintained by Redhat and Somnium. Takatuka and Darjeeling Both, TakaTuka and Darjeeling are Java Virtual Machines (JVM) for embedded devices. The author actively contributed to both projects by porting them to the MSP430 processor platform. Experimenting with JVMs on MSP430 backed sensor nodes was the original stimulus to develop ocapi as the underlying hardware abstraction layer. kagwang and Wireshark As wirelesss communication protocols is a major research concern at IHP, Wireshark is a fundamental tool broadly used to analyze data flow. During a project targetted at the convergence of home network technologies, the author\nadded an IEEE1905.1 protocol filter for Wireshark, named it kagwang and published it under an open source license. Meanwhile, there was feedback from the University of Singapore with this respect.\nFurther potential The use of research–specific OSS seems to be well–established... [explicated in full paper]. However, the biggest potential is in publishing these many tiny helper, applets, driver etc. as OSS, that must be re–invented so often,because they disappear in a lower drawer after a project is finished.\nConclusion For WSN, there are many OSS tools available. Using them may accelerate research projects and increase transparency. Finally, there are only good reasons for making own software particles available to the public.","original_language":"eng","persons":["Oliver Maye"],"tags":["froscon2018","2265","FrOSCon meets

Most applications need a stateful layer which holds the data. There are at least three necessary ingredients which are everything else than trivial to combine and of course even more challenging when heading for an acceptable performance. Over the past years there has been significant progress in respect in both the science and practical implementations of such data stores. In his talk the audience is introduced to some of the needed ingredients, address the difficulties of their interplay and show four modern approaches of distributed open-source data stores.\nTopics are:\n– Challenges in developing a distributed, resilient data store\n– Consensus, distributed transactions, distributed query optimization and execution\n– The inner workings of ArangoDB, Cassandra, Cockroach and RethinkDB\nThe talk will touch complex and difficult computer science, but will at the same time be accessible to and enjoyable by a wide range of developers.","original_language":"eng","persons":["Kaveh Vahedipour"],"tags":["froscon2018","2216","Databases"],"view_count":78,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2023-08-29T18:15:03.137+02:00","length":3349,"duration":3349,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2216-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2216-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/4ea59f56-e783-4bcf-811f-895eedb58398-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/4ea59f56-e783-4bcf-811f-895eedb58398-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2216-the_computer_science_behind_a_modern_distributed_data_store","url":"https://api.media.ccc.de/public/events/4ea59f56-e783-4bcf-811f-895eedb58398","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5740,"event_guid":"325decd8-4e17-42d1-aab7-446e7651a617","weight":1},{"event_id":5748,"event_guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","weight":3},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":4},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":4},{"event_id":5776,"event_guid":"fd9ddda5-892f-4f55-ad36-b47044986bb3","weight":3},{"event_id":5777,"event_guid":"26bca6f5-82ca-47e3-b022-b0d1228f2563","weight":3},{"event_id":5798,"event_guid":"3a02a54b-24df-4c77-8d34-8cadf727f3a7","weight":3},{"event_id":5815,"event_guid":"049bf950-ff7a-4d68-b658-66f611cbdfd7","weight":3},{"event_id":5816,"event_guid":"4a6584de-59fd-405e-be42-ce295cc516f2","weight":3},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":7},{"event_id":5819,"event_guid":"4fd19ecd-d015-4329-b825-cd7bc6541674","weight":3},{"event_id":5820,"event_guid":"d285cec6-c1b3-41bc-bb28-ed499609bd2e","weight":1},{"event_id":5822,"event_guid":"92d1bc03-3224-4dc6-be3a-691e96d641fb","weight":3},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":3}]},{"guid":"3e621fd6-a4c3-4351-ae04-e5666bfec0c5","title":"Datenschutz und Softwaregestaltung","subtitle":"Anforderungen der Datenschutzgrundverordnung","slug":"froscon2018-2207-datenschutz_und_softwaregestaltung","link":"https://programm.froscon.de/2018/events/2207.html","description":"Die Datenschutzgrundverordnung richtet sich an alle, die personenbezogene Daten verarbeiten.

It will demonstrate how Genode's unique system design lends itself to compose a general purpose OS that puts the user in full control without sacrificing security by applying the principle of least privilege from the very beginning.\n\nOver the past decade, the Genode OS Framework has evolved from a research prototype to a practical operating-system foundation. By now it is used by the Genode developers as well as a group of enthusiasts in form of Sculpt day to day. Being a component-based system designed after the principle of least privilege from the very beginning, it breaks with many concepts that we take for granted in traditional operating systems, e.g., the central role of files. Instead, Genode introduces a novel way of composing system scenarios out of building blocks where the building blocks are able to cooperate without ultimately trusting each other. Thus components are isolated sandboxes, whose access to the surrounding environment is managed from the outside and enforce by a microkernel.\n\nIn 2018 the Sculpt system scenario was created to make this system more easily accessible by providing a user interface making it more convient to execute common administrative tasks, e.g. configuring the network, as well as installing and deploying applications.\n\nThis talk will give a brief overview of the architecture of Genode and will show the current state of Sculpt by giving a live demonstration.","original_language":"eng","persons":["Josef Söntgen"],"tags":["froscon2018","2185"],"view_count":111,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-06-16T21:15:05.519+02:00","length":2331,"duration":2331,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2185-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2185-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/652fdd40-d2a0-4955-b2a3-d268d7c53884-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/652fdd40-d2a0-4955-b2a3-d268d7c53884-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2185-exploring_sculpt_a_component-based_operating_system","url":"https://api.media.ccc.de/public/events/652fdd40-d2a0-4955-b2a3-d268d7c53884","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":1983,"event_guid":"HvR3MGqT1NqC3G3aIZJv7A","weight":1},{"event_id":1990,"event_guid":"APxc5qnadHeafxzU1z7FXw","weight":1},{"event_id":2085,"event_guid":"0Yrjp9uKurxoSYw0p2pNdA","weight":1},{"event_id":5204,"event_guid":"376ecc3e-3e92-4c5a-a49e-506709d8d915","weight":1},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":1},{"event_id":5742,"event_guid":"7bd7470f-6197-4356-abb3-73d123f49c87","weight":1},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":1},{"event_id":5787,"event_guid":"4a080f4f-ec05-4c7a-990d-fa26c6227ab5","weight":1},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":1},{"event_id":5797,"event_guid":"b72de5fc-3cd1-4a76-980c-ca48bac7184f","weight":1},{"event_id":5807,"event_guid":"d388bde4-a8b1-4caa-84fb-3f8a6e630afa","weight":1},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":1},{"event_id":5824,"event_guid":"0a8b729c-ebe9-48f3-a30a-7b422fccbc0d","weight":1},{"event_id":5825,"event_guid":"d535dfae-c59a-4a72-9d86-94e3ce66e549","weight":1},{"event_id":5828,"event_guid":"b36d437f-7643-422d-b429-316a83826304","weight":1},{"event_id":5829,"event_guid":"9b34e4d2-533b-44ac-94c9-d53a70bc11a8","weight":1},{"event_id":5831,"event_guid":"5fa9fb17-3bb5-43c2-9ef9-3ed9db1c957a","weight":1},{"event_id":6078,"event_guid":"8a3c7006-ba7f-451c-a555-3a9ca4af5f2f","weight":1},{"event_id":6185,"event_guid":"7ae956e6-3ad3-5c07-8f24-8e7ca0ed2607","weight":1},{"event_id":6294,"event_guid":"8166f860-131c-4b0d-b6ee-bfb280626e06","weight":1},{"event_id":6367,"event_guid":"68fdc36a-4042-5ae3-be15-fff3fd5d7c54","weight":1}]},{"guid":"d85ab00f-b631-4e1e-a930-329722774f40","title":"12 years as QA in Agile Teams - what has worked and what hasn't","subtitle":"Tales and experiences with people, ways of working, and software tools","slug":"froscon2018-2133-12_years_as_qa_in_agile_teams_-_what_has_worked_and_what_hasn_t","link":"https://programm.froscon.de/2018/events/2133.html","description":"For 12 years I have worked as a QA in many international teams that have tried agile techniques to various degrees. Usually the teams included developers, testers/QAs and UX/UI designers. Although we mainly worked on commercial products, we used many freely available tools during development. This talk will focus on our experiences with agile techniques and processes, from \"Definition of Ready\" and \"Definition of Done\" to code reviews and releasing with CI/CD.\n\nProcesses are important to help develop products in a structured way. But processes need to be adapted to make them work. We have adapted our ways of working based on the products that we worked on and depending on the people that were on the teams. The teams I have worked with have been very international. Usually co-located, but we often have someone working remotely and we have also worked with offsite teams. I have worked on various mobile platforms and on products that were focused on one platform but also on cross-platform teams with 2 Android, 2 iOS, and 2 Web developers in one scrum team. Things I will talk about will include\n- how we do code reviews using gerrit\n- our experience with estimates\n- what we learned from shuffling teams every 3 months\n- things that we seem to struggle with in every project","original_language":"eng","persons":["Elke Moritz"],"tags":["froscon2018","2133","Development"],"view_count":159,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-01-27T17:45:11.583+01:00","length":3615,"duration":3615,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2133-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2133-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/d85ab00f-b631-4e1e-a930-329722774f40-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/d85ab00f-b631-4e1e-a930-329722774f40-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2133-12_years_as_qa_in_agile_teams_-_what_has_worked_and_what_hasn_t","url":"https://api.media.ccc.de/public/events/d85ab00f-b631-4e1e-a930-329722774f40","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":3424,"event_guid":"915aced0-8526-4087-b0c3-769710ef6322","weight":8},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":13},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":6},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":10},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":4},{"event_id":5765,"event_guid":"cc58e79c-5a9f-43cf-80da-6dca94b402c4","weight":6},{"event_id":5808,"event_guid":"daa949b6-e0b2-4f4d-bd98-a9241f6d09c4","weight":7},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":7}]},{"guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","title":"Sichere Netzwerke mit pfSense","subtitle":null,"slug":"froscon2018-2150-sichere_netzwerke_mit_pfsense","link":"https://programm.froscon.de/2018/events/2150.html","description":"pfSense ist eine auf FreeSD basierende Open source Firewall/Router Software. Dieser Vortrag beschäftigt sich mit den Möglichkeiten von pfsense und der Frage warum man sich mit den umfangreichen Fähigkeiten beschäftigen sollte. \n\n\nFirewalls  und Sicherheit gehören zum IT-Alltag (oder sollten es zu mindestens). Bei den Anforderungen an eine solche Komponenten sollte man sich nicht nur auf die Internet Provider oder den Herstellernamen verlassen.\n\nDie pfSense Firewall ist eine high performance Firewall für den wachsenden Bedarf an diese wichtige Netzwerkkomponenten. Sie verfügt auch über weitere Funktionen wie VPNs, Ausfallsicherheit, Traffic Shapping oder IDS die sonst eher den teuren Enterprise Produkten vorbehalten sind. \n\nDenn auch ohne umfangreiche Investitionen lassen sich viele unternehmenstypische Anforderungen auch für kleine Unternehmen oder den gehobenen Heimarbeitsplatz implementieren. \n\nDieser Vortrag soll die Basisinformationen aufzeigen und erläutern welche komplexeren Aufgaben ohne große Investitionen bewältigen werden können.

Mit Bounded Context und Self Contained Systems erhält man besser geschnittene und verständlichere Komponenten.\n\nDomain Driven Design ist eine Entwicklungs- und Modellierungsstrategie, welche von Eric Evans bereits vor einigen Jahren postuliert wurde. Der Kern von Domain Driven Design bildet dabei die eigentliche Fachdomäne als Herz und Mittelpunkt der zu erstellenden Software.\n\nEntwickler und Fachexperten entwickeln in enger Kommunikation zusammen ein Vokabular, die so genannte „Ubiquitous Language“ mit dessen Hilfe sie wiederum ein gemeinsames Modell und Verständnis der Fachdomäne entwickeln. Dieses gemeinsam erstellte Modell zieht sich in der weiteren Entwicklung wie ein roter Faden durch alle Prozesse, sei es auf technischer wie fachlicher Ebene, sodass alle beteiligten zu jeder Zeit ein gutes Verständnis der Domäne haben.\nInnerhalb dieses Modells lassen wiederum mit allen beteiligten einzelne „Bounded Contextes“  identifizieren, welche eine abgeschlossene fachliche Domainlogik innerhalb des Modells identifizieren und untereinander in Relation bringen lassen.\n\nAuf technischer Ebene lässt sich nun mit „Bounded Contextes“ eine gute Brücke in Richtung der Microservicearchitektur schlagen. Zusammen mit diesen beiden Strategien erhält man am Ende fachlich sauber geschnittene self contained Systems, die einer Terminologie folgen, welche auch von Domainexperten, Stakeholdern oder zumindest vom Product Owner zusammen mit Entwicklern verstanden, getragen und auch erweitert wird.\n\nDer Talk erläutert die Grundbegriffe des Domain Driven Designs und das theoretische Konzept dahinter und schlägt im Anschluss mit Domainkontexten eine Brücke zur Softwarearchitektur.

Subnetting nach CIDR bildet die Grundlagen für Routing in heutigen IP-Netzwerken;\nRFC1918, RFC3927 und RFC6598 definieren jeweils “private” IP-Bereich für interne Nutzung, für öffentliche IPs haben wir in Europa das RIPE.

Diese Bewegung hat uns  neue Protokolle wie VXLAN und eine Hand voll \"open networking\" Plattformen gebracht, mit denen wir nicht mehr in der Herstellerabhängigkeit gefangen sind, sondern uns Control Plane Software aus einer Menge von Linux-basierten Angeboten auswählen können und nach eigenem Belieben verwalten und orchestrieren können.\n\nDank Linux als Basis und dem starken Open Source Gedanken einiger \"open networking\" Hersteller sind heute einige Features Teil des Standard Linux-Kernels geworden (VRFs, MPLS forwarding plane, ...) und somit für jedermann frei verfügbar. Hervorzuheben sind die Veröffentlichungen der Debian-basierten Plattform von Cumulus Networks, die VRF-Support für Linux, MPLS patches für FRR und ifupdown2 enthalten.\n\nWenn man einige dieser Ideen und Technologien zusammensteckt eröffnen sich einem mächtige neue Möglichkeiten, um mit einem niedrigen Budget leistungsstarke Netzwerke zu bauen. Dieser Vortrag wird am Beispiel der Server- und Netzwerkinfrastruktur des Freifunk Hochstifts aufzeigen, wie man mit Hilfe von Salt Stack, etwa 1.000 Zeilen Python und einem Stapel günstiger Hardware ein Service-Provider-ähnliches Netzwerk aufbaut, in dem Overlays und Anycast keine Dinge sind, vor denen man Angst haben muss.","original_language":"deu","persons":["Maximilian Wilhelm"],"tags":["froscon2018","2252","Network Track"],"view_count":483,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-06-25T16:00:05.162+02:00","length":2509,"duration":2509,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2252-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2252-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/92d1bc03-3224-4dc6-be3a-691e96d641fb-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/92d1bc03-3224-4dc6-be3a-691e96d641fb-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2252-sdns_im_eigenbau_-_der_pinguin_dirigiert_das_netzwerk","url":"https://api.media.ccc.de/public/events/92d1bc03-3224-4dc6-be3a-691e96d641fb","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":29},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":21},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":14},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":11},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":31},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":11},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":6},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":30},{"event_id":5786,"event_guid":"ddcadb48-0ea6-4bbd-8823-57b70e394afc","weight":34},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":42},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":16},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":12},{"event_id":5802,"event_guid":"281464f3-4783-4c82-8e55-709b6ccee776","weight":34},{"event_id":5810,"event_guid":"291fe17d-80ca-46a9-9978-c61509a4f9c9","weight":24},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":40},{"event_id":5819,"event_guid":"4fd19ecd-d015-4329-b825-cd7bc6541674","weight":9},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":36}]},{"guid":"99b060b6-4207-40a3-9b6a-da340b8f0403","title":"Performance Analysis in the Cloud","subtitle":"A Reflective Practitioner's Perspective","slug":"froscon2018-2111-performance_analysis_in_the_cloud","link":"https://programm.froscon.de/2018/events/2111.html","description":"This talk situates the art and science of performance analysis (in the cloud), in a framework of reflective practice as outlined in Donald A. Schön's book \"The Reflective Practitioner: How Professionals Think in Action\" (1983). \n\n\n\nPlacing performance analysis in such a framework can help operators transcend an overwhelming spectrum of challenges and focus on work that matters. For eg., its important to see through the common expectations that modern enterprises might have of cloud providers - a plug-and-play mindset, where plugging-in is easy, but where play can sometimes cost millions of dollars in operating cost, raising questions about the cloud's effectiveness as a platform. With such a mindset, performance engineering might be considered unimportant, where it might actually be most useful. But that's only the tip of the iceberg. Once an operator has gathered the grit and resources to continue with performance analysis - the assumptions of fellow engineers, developers and leaders must also be addressed, and a process of edification and implementation should be carried out - sometimes this can be a draining process for a single operator - as it involves answering misinformed skepticism from different directions. Last but not the least - meaningful performance analysis in the cloud might even be a pipe dream for most - as its not easy to get the right information (if at all) from cloud vendor engineers and architects, for deeper questions and investigations around available monitoring data, without which useful performance modeling is impossible.\n\nNonetheless, the insights gained with such practice can be helpful overall, in defining performance and capacity planning strategies. In this talk specifically, many anecdotes about various software tools and enterprise application platforms will be discussed to illustrate the points mentioned above, which can be used by operators to make improvements in their environment. - for eg.,\n* How to model disk usage for a popular big data software - with a queuing model, or linear regression? If using a queueing model, does your cloud vendor provide all the metrics? Are those metrics really what they appear? Does your operating system agree? \n* Metrics, metrics everywhere, but oops! there's a performance issue with the central metrics system.

Dabei liegen die Einstiegshürden so niedrig, dass auch Anfänger nach kurzer Einarbeitungszeit komplexe Anwendungen kreieren können. Nach einer kurzen Einführung in das Thema, werden, an Hand ausgewählter Anwendungsszenarien, verschiedene Einsatzmöglichkeiten von Node-RED aufgezeigt, bei denen auch fortgeschrittene Programmierer nicht zu kurz kommen sollen.\n\nZuerst wollte ich, ein „überzeugter“ beruflicher und privater Softwareentwickler, mich gar nicht mit Node-Red auseinandersetzen. Das einfache „Zusammenschieben und Verbinden“ von Softwarebausteinen entsprach irgendwie nicht meiner „Berufsehre“...;-). Aber immer wieder bin ich, bei der Beschäftigung mit dem Internet der Dinge (IoT), Hausautomatisierung, Sammeln/Verarbeiten von Sensordaten, deren Visualisierung etc., über Node-RED gestolpert.\n\nMein Gewissen: „Hallo Uwe! Vielleicht solltest du dir doch einmal diese Klickibunti-Entwicklungsumgebung genauer ansehen..., um sie danach in der Luft zu zerreißen und für immer aus deinem Werkzeugkasten zu verbannen...!?“\n\nGedacht, getan:\n\u003cul\u003e\n\u003cli\u003eZuerst sehr skeptisch → Was hat das eigentlich noch mit Programmieren zu tun?\u003c/li\u003e\n\u003cli\u003eDann doch überrascht → Hey, da gehen ja Dinge in 10min, für die man sonst nächtelang rumprogrammieren muss!\u003c/li\u003e\n\u003cli\u003eHmm, meine Daten passen nicht ins vorgedachte „Node-RED-Schema“... → Ach so, man kann ja doch richtig programmieren! ...wo ist mein angestaubtes JavaScript-Buch?\u003c/li\u003e\n\u003cli\u003eOk: Datenströme, elegant in die richtigen Bahnen gelenkt, können auch ästhetisch aussehen...:-)\u003c/li\u003e\n\u003c/ul\u003e\n\nIm Rahmen des Vortrages wird eine Lanze für die browserbasierte Entwicklungsumgebung Node-RED gebrochen. Es wird erklärt:\n\u003cul\u003e\n\u003cli\u003ewas Node-RED eigentlich ist,\u003c/li\u003e\n\u003cli\u003ewo und wie man es installiert,\u003c/li\u003e\n\u003cli\u003ewie es funktioniert und Node-RED-Anwendungen erstellt\u003c/li\u003e\n\u003c/ul\u003e\n\nSoweit wie möglich, werden die Erläuterungen an Hand von mehr oder weniger sinnvollen Beispielen erfolgen. Dabei wird gezeigt, wie man Daten aus unterschiedlichsten Quellen gewinnt und diese nach seinen Bedürfnissen anpasst, um sie z.B. im Nachgang in geeigneter Art und Weise zu visualisieren.\n\nLetztendlich soll der Zuhörer dazu animiert werden, sich selbst mit Node-RED zu beschäftigen und ein wenig zu experimentieren.","original_language":"deu","persons":["Uwe

her. Netfilter und seine Userlandtools ip(6)tables (u.a.) sind seit 2001 im Kernel und damit fast erwachsen. In der Zwischenzeit haben neue Technologien Einzug in das Linux-Ökosystem gehalten; iptables wird weiterhin eingesetzt. Es hat sich auch aufgrund seiner Vielseitigkeit von einer Paketfilterimplementierung zu einem unterstützendem Werkzeug für Anwendungen wie Routing, NAT, Applicationlevelproxying, Deep Packet Inspection (DPI), Traffic Shaping und vielem mehr entwickelt.\n\nDieser praxisorientierte Vortrag soll  die Motivation und Konzepte von  Paketfiltern behandeln. \nRegeln sind die Bausteine von iptables. Es wird geklärt:\n- Woraus bestehen diese?\n- Wie erstellt man Regeln?\n- Was sind Tabelle, Ketten, Matches und Targets?\n\nAnhand von realen Beispielen wird der Aufbau von Regelwerken aufgezeigt.\nEs entstehen schnell große Regelsets. Tipps für das Regelmanagement sollen aufzeigen wie man der Regeln Herr wird.\n\nIptables kann nicht nur filtern: über Features wie Conntrack und NAT wird aus dem Leben berichtet.\nEs soll gezeigt werden, was iptables sonst noch für Dich tun kann.\n\nErsetzende und ergänzende Technologien sind bereits im Kernel: nftables und bpfilter.

In der klassischen Softwareentwicklung ist Industrialisierung und Shoring inzwischen weit verbreitet.  devonfw ist der Capgemini-Ansatz, der die beiden Welten verbindet, um eine industrialisierte Entwicklung von Microservices im DevOps Modell zu ermöglichen. devonfw besteht aus einem Architektur-Blueprint, Softwarekomponenten (OpenSource), Dokumentation, Best Practices, Entwicklungsumgebung und DevOps Toolchain. Eine internationale Community von 600 Architekten und Entwicklern arbeitet mit einem dedizierten Team an der Wartung und Weiterentwicklung.\n\n\nAuch bei Auschöpfung der üblichen Verdächtigen - Spring Boot mit modernsten Empfehlungen, Maven, Jenkins, Eclipse/IntelliJ etc. - bleibt erfahrungsgemäß einiges an Gestaltungsspielraum. Bibliotheken, Frameworks und Werkzeuge bieten für die meisten Aufgabenstellungen mehrere Lösungen. Insbesondere das innere Design einer Software ist noch festzulegen. Devonfw verfolgt das Ziel, eine umfassende, unmittelbar einsetzbare Komplettlösung zu bieten - bestehend aus:\n- vorkonfigurierter Eclipse IDE,\n- Architekturmustern und Maven Archetypes für Java Backends, Microservice Infrastruktur-Services, Microservices,\n- DevOps-tauglichen Konfigurationen und Werkzeugen für Build, Test, Package, Deploy, statische Code-Analyse und automatische Tests,\n- mehreren hundert Seiten Dokumentation,\n- erweitertem Angular TypeScript Client Seed,\n- Trainingsunterlagen,\n- einer umfangreichen Beispielanwendung sowie\n- Unterstützung für diverse Spezielthemen.\n\nGestartet wurde devonfw als schlanke Open-Source-Architektur durch Kombination verbreiteter Teillösungen. Die Gestaltung (Design Authority) liegt in der Hand von Architekten verschiedener Einheiten, die mittels Forenbeiträgen und -umfragen ein offenes Ohr für die Community pflegen. Nach wie vor liegt der Fokus auf Patterns und Best-Practices – technisch, aber auch methodisch. Neben einem hochskalierbaren Design für Modularisierbarkeit und Lastverträglichkeit unterstützt devonfw heute Microservice-Architekturen, End-to-End-Testing, Cloud-Deployment und DevOps.\n\nIn den Hauptbestandteilen OASP4J für Java-Backends und OASP4JS für Angular/TypeScript-Frontends sind zwei Releases pro Jahr üblich. Die Community liefert im Umfeld weitere wichtige Beiträge, so zum Beispiel für OASP4Mobile für mobile Clients und OASP4fn für Serverless Applikationen.\n\nMit den ersten Projekterfolgen gewann das Kernteam die Unterstützung des Top-Managements als Sponsor. Dies ermöglichte in 2018, devonfw als Open-Source-Produkt der Allgemeinheit zur Verfügung zu stellen. Seine Eignung für Cloud-native Entwicklungen belegen Auszeichnungen als „Primed by Red Hat for OpenShift“ und IBM’s „Ready for IBM Cloud“. \n\nDer Vortrag erläutert die Zielsetzung von devonfw sowie dessen Bestandteile und wie es sich als Open-Source-Produkt darstellt.","original_language":"deu","persons":["Axel Burghof"],"tags":["froscon2018","2199","Cloud"],"view_count":73,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-01-04T13:45:12.733+01:00","length":3634,"duration":3634,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2199-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2199-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/2ab2039e-11a3-4646-98c0-d637d0463673-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/2ab2039e-11a3-4646-98c0-d637d0463673-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2199-devonfw_-_framework_fur_cloud-native_anwendungen","url":"https://api.media.ccc.de/public/events/2ab2039e-11a3-4646-98c0-d637d0463673","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":3426,"event_guid":"96d9e96d-3a35-41bc-8528-09351e8fb2f4","weight":1},{"event_id":3428,"event_guid":"7d2ccfda-ae1f-47a9-8d0a-c1c6c270614a","weight":1},{"event_id":4388,"event_guid":"223bd212-14a2-40e7-9b37-18db6da70dca","weight":1},{"event_id":4412,"event_guid":"7d71a2b2-3a4b-473c-9eb4-41c1b33990d0","weight":2},{"event_id":4418,"event_guid":"00ac6281-8db2-47af-9b12-22f9404368ac","weight":1},{"event_id":4419,"event_guid":"d9e29339-b716-4eea-a640-fb0e75753de2","weight":1},{"event_id":4434,"event_guid":"b9ae583a-4b02-4bd4-af79-4b5766f84e25","weight":1},{"event_id":4440,"event_guid":"2ce31c5d-ecbb-4da6-9c4d-a596d1b93b1c","weight":1},{"event_id":4453,"event_guid":"563fc802-cfce-4bec-b20c-303a1d3f623a","weight":1},{"event_id":4457,"event_guid":"da3e484f-a48f-44c6-819d-1a15669f6ed7","weight":1},{"event_id":4484,"event_guid":"d505da11-6f92-447b-bb2f-3e512caae41a","weight":2},{"event_id":5235,"event_guid":"52535255-5245-2020-2020-202020202020","weight":2},{"event_id":5244,"event_guid":"4a473753-5039-2020-2020-202020202020","weight":1},{"event_id":5274,"event_guid":"c38c514b-99f4-4906-a0e5-189df72dbd9e","weight":1},{"event_id":5443,"event_guid":"be758761-e7e8-5c35-894c-abca5f0876e4","weight":1},{"event_id":5732,"event_guid":"e9fdf337-3b08-429c-a107-4a965cc4bb85","weight":1},{"event_id":5742,"event_guid":"7bd7470f-6197-4356-abb3-73d123f49c87","weight":1},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":2},{"event_id":5760,"event_guid":"69525bea-9f07-48b8-9262-d39cdeb1e301","weight":1},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":2},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":2},{"event_id":5776,"event_guid":"fd9ddda5-892f-4f55-ad36-b47044986bb3","weight":1},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":1},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":1},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":1},{"event_id":5815,"event_guid":"049bf950-ff7a-4d68-b658-66f611cbdfd7","weight":1},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":2},{"event_id":5820,"event_guid":"d285cec6-c1b3-41bc-bb28-ed499609bd2e","weight":2},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":2},{"event_id":5832,"event_guid":"fcae0fe2-fc3b-466f-85d5-4777cd46099d","weight":1},{"event_id":5972,"event_guid":"8a208625-2513-5e71-956d-d28245e2389d","weight":1},{"event_id":5975,"event_guid":"456fb60c-5ce7-11e8-be47-1fb2912eb892","weight":1},{"event_id":6098,"event_guid":"289155d4-9fab-46ad-86e6-6db5d065e44a","weight":1}]},{"guid":"72e46e27-0667-4dca-bacd-128e55287e37","title":"InnerSource: Open Source collaboration patterns beyond public FOSS projects","subtitle":null,"slug":"froscon2018-2118-innersource_open_source_collaboration_patterns_beyond_public_foss_projects","link":"https://programm.froscon.de/2018/events/2118.html","description":"This year marks the 20th birthday of the Open Source movement. Wikipedia highlights on aspect crucial to open source software development by describing it as “collaborative development from multiple independent sources”. During the past decades people of all trades have found ways to collaborate on OSS projects that span organisational, timezone and geographic boundaries.\n\nFor years in particular those active in OSS projects have been advocating to bring the collaboration practices they knew of open source over to their respective in-house teams. The resulting practice goes under multiple names: Open Development, Internal Open Source, Inner Source.\n\nFor the past year, Europace AG, a Berlin based FinTech, has been piloting InnerSource efforts. During that time, work was closely following (and contributing results back to) innersourcecommons.org - a global, cross-organization initiative to further InnerSource practices that “apply the lessons of Open Source to all software engineering, using collaboration and transparency to increase quality, speed, and developer joy”.\n\nThis talk will take you on a journey from a vague idea towards an organisation that embraces Open Source collaboration techniques internally. Towards an organisation in which a growing number of developers are starting to get involved with Open Source projects themselves.","original_language":"eng","persons":["Isabel Drost-Fromm"],"tags":["froscon2018","2118","Culture"],"view_count":61,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2024-09-18T16:15:01.794+02:00","length":2244,"duration":2244,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2118-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2118-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/72e46e27-0667-4dca-bacd-128e55287e37-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/72e46e27-0667-4dca-bacd-128e55287e37-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2118-innersource_open_source_collaboration_patterns_beyond_public_foss_projects","url":"https://api.media.ccc.de/public/events/72e46e27-0667-4dca-bacd-128e55287e37","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5722,"event_guid":"906c5611-7e85-4593-8a4e-b33dedfce19e","weight":2},{"event_id":5732,"event_guid":"e9fdf337-3b08-429c-a107-4a965cc4bb85","weight":2},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":3},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":2},{"event_id":5747,"event_guid":"eb9f24f2-5094-4419-a806-ff7cfb432ed4","weight":2},{"event_id":5748,"event_guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","weight":3},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":4},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":3},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":2},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":1},{"event_id":5767,"event_guid":"dbb0c6bc-d14f-4d9b-9c9e-f66fa0143721","weight":1},{"event_id":5768,"event_guid":"cbec40e2-8dfa-46c0-b3ae-3a991876cad7","weight":2},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":1},{"event_id":5774,"event_guid":"191e9835-4941-4f73-9c80-d453d684bb03","weight":3},{"event_id":5776,"event_guid":"fd9ddda5-892f-4f55-ad36-b47044986bb3","weight":2},{"event_id":5780,"event_guid":"62e8df5f-cd0b-4606-8d61-18b274e1d048","weight":1},{"event_id":5781,"event_guid":"60b11faf-4afc-4c25-bae5-a59d48bda32a","weight":3},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":2},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":2},{"event_id":5787,"event_guid":"4a080f4f-ec05-4c7a-990d-fa26c6227ab5","weight":2},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":3},{"event_id":5790,"event_guid":"f9c7f1a4-a696-4559-9d65-52e770591c38","weight":3},{"event_id":5791,"event_guid":"9144aaee-4cb6-4497-89d9-acca7da85730","weight":1},{"event_id":5793,"event_guid":"05d2f707-19a8-491d-a375-13280c771034","weight":3},{"event_id":5796,"event_guid":"1098b55f-fe7c-4347-8f64-91b3d3c36322","weight":3},{"event_id":5807,"event_guid":"d388bde4-a8b1-4caa-84fb-3f8a6e630afa","weight":2},{"event_id":5808,"event_guid":"daa949b6-e0b2-4f4d-bd98-a9241f6d09c4","weight":1},{"event_id":5811,"event_guid":"b9affdeb-41c2-4322-8a5a-1c7676372ea9","weight":1},{"event_id":5817,"event_guid":"75c4c7ff-7dc3-4e9d-a834-087be2ea9a9e","weight":1},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":3},{"event_id":5821,"event_guid":"d7d5d572-075e-475e-a9cd-53e4217d8b15","weight":3},{"event_id":5824,"event_guid":"0a8b729c-ebe9-48f3-a30a-7b422fccbc0d","weight":2},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":3},{"event_id":5831,"event_guid":"5fa9fb17-3bb5-43c2-9ef9-3ed9db1c957a","weight":2}]},{"guid":"1098b55f-fe7c-4347-8f64-91b3d3c36322","title":"Freedom and Privacy in the Datacenter","subtitle":null,"slug":"froscon2018-2170-freedom_and_privacy_in_the_datacenter","link":"https://programm.froscon.de/2018/events/2170.html","description":"Most servers used in the Datacenter run a proprietary BIOS, the Intel Management Engine firmware and some vender specific remote management. Virtual machines are unsafe since the server\noperator can automatically extract cryptographic keys from the RAM. There are some freedom respecting servers such as the Vikings D16 1U server which has OpenBMC by Raptor Engineering. Since OpenBMC is free software it can be audited for security. In August 2017, Raptor Engineering has launched a new series of workstation and server computers, called the Talos II. These are high-end systems, using the libre IBM POWER9 architecture.\n\nMost servers use Intel or AMD processors which require multiple binary blobs\nto function. There are some libre ARM systems, but those offer low performance.\nHigh performance 64 bit ARM systems use a non-free UEFI implementation. \nBoth the Intel Management Engine and AMD Platform Security Processor require\nproprietary firmware. However there is an older AMD system (the ASUS KGPE-D16)\nthat is supported by Libreboot and OpenBMC. This system does not need any\nmicrocode updates to be usable as a server.\nThe new Talos II system uses up to two IBM POWER9 Sforza CPU modules and an\nAspeed AST2500 Server Management Processor.

Es wird dabei explizit auf die ambivalenten Wirkungen von entwickelter Software eingegangen. Der Vortrag soll zum kritischen Nachdenken über die Verantwortung eines jeden Entwicklers anregen und Grundlage für spätere Diskussionen sein.\n\n\nDie Entwicklung von komplexen Softwarelösungen wird zunehmend unübersichtlicher und Entwickler arbeiten vermehrt in kleineren Teams an Komponenten eines Gesamtsystems. Oftmals ist es für den Entwickler somit nur schwer oder kaum möglich, nachzuvollziehen wofür der von ihm geschriebene Code letztendlich verwendet wird.\nEine zentrale Frage ist jedoch die Verantwortung des Entwicklers und wie diese getragen wird. Dies erfordert allerdings nicht nur eine Diskussion auf der ethischen Ebene, sondern dass kritische Hinterfragen des eigenen Handelns muss konkret in die tägliche Arbeit übernommen werden.\nEinen Ansatz hierfür liefert die Technologiefolgenabschätzung, wo beispielsweise die Potenziale, Risiken aber auch der Missbrauch von Technologien untersucht werden [1].\n\nIn diesem Beitrag werden anhand von konkreten Praxisbeispielen die ambivalenten Wirkungen von Softwarelösungen auf Natur, Mensch, Organisation und Gesellschaft aufgezeigt.\nDie Beispiele gehen von dem Einsatz von Sozialmedia über die Integration von Fremdsystemen bis hin zu eigenständigen Anwendungen die einfache Datenverarbeitung und -ausgabe machen, dabei spielt auch immer ein Rolle inweit eine Freie Lizenz die Effekte verändern.\nSo wird insbesondere gezeigt was vermeintlich \"kleine\" Anwendungen/Änderungen an einem Programm für positive wie negative Auswirkungen haben können. Der Vortrag erfolgt hierbei aus der Perspektive eines Entwicklers und zeigt die verschiedenenen Wirkungsebenen und -effekte eines IT-Produktes auf und was konkret getan werden kann als \"kleiner\" Entwickler.\nDer Vortrag soll dabei ausgehend von eigenen persönliche Erfahrungen und Anregungen zum kritischen Nachdenken über die eigenen Programme anregen.\nEin anschließender Austausch innerhalb der Entwicklergemeinde ist angestrebt und sehr erwünscht. \n\n[1] Fuchs-Kittowski, Klaus. \"Zur Ambivalenz der Wirkungen moderner Informations- und Kommunikationstechnologien auf Individuum, Gesellschaft und Natur.\" Sitzungsberichte, Leibniz-Sozietät der Wissenschaften zu Berlin (2011): 161-184.","original_language":"deu","persons":["Adrian Böhmichen"],"tags":["froscon2018","2217","Culture"],"view_count":78,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-02-13T16:00:06.076+01:00","length":2888,"duration":2888,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2217-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2217-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/75d71314-74b8-43c4-893f-c1ddb0cc050b-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/75d71314-74b8-43c4-893f-c1ddb0cc050b-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2217-folgeabschatzung_meines_programms","url":"https://api.media.ccc.de/public/events/75d71314-74b8-43c4-893f-c1ddb0cc050b","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":4930,"event_guid":"9a0efbf6-94d6-4c86-864c-caa1f3e929c7","weight":1},{"event_id":5727,"event_guid":"702996dd-0853-4d00-81e2-3e39cae19500","weight":1},{"event_id":5732,"event_guid":"e9fdf337-3b08-429c-a107-4a965cc4bb85","weight":4},{"event_id":5735,"event_guid":"d494138e-2442-4b08-b06b-43e1aa444701","weight":4},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":8},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":5},{"event_id":5755,"event_guid":"8ab1c7ea-00ee-4f1a-8e5a-7b60ec80408f","weight":2},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":4},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":4},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":4},{"event_id":5762,"event_guid":"ae6e36cb-713c-4b73-99ac-f1b95f910e32","weight":1},{"event_id":5769,"event_guid":"76ad2dd9-6054-44b4-a969-eb8f1bf87d62","weight":6},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":4},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":6},{"event_id":5796,"event_guid":"1098b55f-fe7c-4347-8f64-91b3d3c36322","weight":4},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":4},{"event_id":5819,"event_guid":"4fd19ecd-d015-4329-b825-cd7bc6541674","weight":4},{"event_id":5823,"event_guid":"7c5c320f-da0f-466f-b312-49cef37d862c","weight":5},{"event_id":5825,"event_guid":"d535dfae-c59a-4a72-9d86-94e3ce66e549","weight":4},{"event_id":5829,"event_guid":"9b34e4d2-533b-44ac-94c9-d53a70bc11a8","weight":4},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":4}]},{"guid":"05d2f707-19a8-491d-a375-13280c771034","title":"Lightning Talks","subtitle":null,"slug":"froscon2018-2322-lightning_talks","link":"https://programm.froscon.de/2018/events/2322.html","description":"Lightning talks are 4-5 minute talks by you about your awesome project, weird issues, systems, concepts or some made-up technique.\n\nLightning Talks is a daily event, which consists in one hour of several short talks.

a crucial skill for people who are interested in Data Science and Machine Learning. Until now, most of the people who are doing Data Science have a strong background in math, usually, people with master or Ph.D. degrees.\n\nHowever, this fact seems to change in the next years, after the hype of Machine Learning we are facing a process of democratization. Now the door of Data Science is open for everyone.\n\nTo truly madly deeply understand how the machine learning algorithms work we need to understand some mathematical concepts. In this tutorial, I would like to share my experience in the process of learning some of those concepts.\n\nWhat I want to do is build a bridge between those concepts and Python, more specifically, SciPy and NumPy and TensorFlow. Basically, this talk is just another tutorial about vectorization, in this case, oriented to understand and implement machine learning algorithms and the mathematical foundation that supports it.\n\nOutline\nReview of linear algebra: A brief review of essential linear algebra, concepts and the explanation with NumPy: scalars, vectors, matrices, tensors, multiplication of vectors, inner products, vector spaces, etc.\nReview of machine learning: A summary of essential machine learning, concepts that are related to mathematical concepts: dimensionality reduction, principal component analysis, etc.\nOptimization: Analytical vs. numerical solutions. This part has too many formulas, well, not too many.\nVectorization: Numpy and TensorFlow.\nSmall practical cases:\nI want to show how we can solve the XOR problem with only one neuron\nExplain the math behind recurrent neural networks.","original_language":"eng","persons":["Omar Gutiérrez"],"tags":["froscon2018","2220","Blessed by the algorithm"],"view_count":178,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-06-15T11:00:03.071+02:00","length":2063,"duration":2063,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2220-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2220-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/3a02a54b-24df-4c77-8d34-8cadf727f3a7-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/3a02a54b-24df-4c77-8d34-8cadf727f3a7-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2220-from_linear_algebra_to_machine_learning","url":"https://api.media.ccc.de/public/events/3a02a54b-24df-4c77-8d34-8cadf727f3a7","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":4539,"event_guid":"384d5955-3745-2020-2020-202020202020","weight":7},{"event_id":5330,"event_guid":"d4965df6-fd2c-5b12-bfb7-1302b2827ba5","weight":9},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":6},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":4},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":4},{"event_id":5748,"event_guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","weight":10},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":5},{"event_id":5757,"event_guid":"fbec0a5a-7a3b-485d-8c50-e732dcea014f","weight":6},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":4},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":4},{"event_id":5778,"event_guid":"c18d8138-d063-4f42-a5ba-d48c9e617714","weight":4},{"event_id":5780,"event_guid":"62e8df5f-cd0b-4606-8d61-18b274e1d048","weight":7},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":5},{"event_id":5791,"event_guid":"9144aaee-4cb6-4497-89d9-acca7da85730","weight":2},{"event_id":5793,"event_guid":"05d2f707-19a8-491d-a375-13280c771034","weight":3},{"event_id":5795,"event_guid":"d3821dc9-94af-438a-af6a-d4f79df43a2f","weight":2},{"event_id":5809,"event_guid":"68e5d6b9-b0cb-4317-b724-5f45145c7eba","weight":5},{"event_id":5813,"event_guid":"4ea59f56-e783-4bcf-811f-895eedb58398","weight":3},{"event_id":5823,"event_guid":"7c5c320f-da0f-466f-b312-49cef37d862c","weight":4},{"event_id":6400,"event_guid":"527b56af-8d56-4edb-9027-9ca60767c742","weight":5}]},{"guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","title":"AI and the End of the World","subtitle":"(as we know it)","slug":"froscon2018-2237-ai_and_the_end_of_the_world","link":"https://programm.froscon.de/2018/events/2237.html","description":"Like any other tool, AI has its benefits and its dangers.

Analysis and evaluation of medical image data such as computed tomography (CT) scans are commonly used to support experts in their diagnosis and are crucial for the selection of further treatment.\n\nThe systematic detection of tumors by an automated system is a challenging task, as several sub-steps such as preprocessing, segmentation, feature extraction and classification have to be considered. We present state of the art methods and solutions for each of these sub-steps as well as a novel approach for a complete\nautomated system for tumor detection and diagnosis in lung CT-Scans. We will explain and compare the different approaches for segmentation and classification used in the context of the SPIE-AAPM Lung CT Challenge.\nAt last, we briefly present the methodologies and results of our approach. We explain how different image processing methods such as morphological operations, connected component labeling and marker-based watershed transformation can be combined to archive a successful segmentation of lung CT-scans using the open source software library OpenCV, while also discussing challenges and limitations of the proposed method.","original_language":"eng","persons":["Tim Adams"],"tags":["froscon2018","2260","FrOSCon meets Science"],"view_count":234,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-04-03T20:00:04.430+02:00","length":2539,"duration":2539,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2260-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2260-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/659ad4fe-93cd-4cb9-a273-7956b96ab02f-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/659ad4fe-93cd-4cb9-a273-7956b96ab02f-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2260-automated_lung_tumor_diagnosis_in_medical_image_data_-_methods_challenges_and_perspectives","url":"https://api.media.ccc.de/public/events/659ad4fe-93cd-4cb9-a273-7956b96ab02f","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":1107,"event_guid":"import-575502e1e9906233c7","weight":1},{"event_id":1924,"event_guid":"0_vboNiskfaosp862h7D0g","weight":2},{"event_id":4387,"event_guid":"9910a89c-ce50-4b0d-80a2-930e4bda8574","weight":1},{"event_id":4416,"event_guid":"34018489-1047-46ad-9512-877129118708","weight":1},{"event_id":4429,"event_guid":"3f680e84-b37d-40d7-8f54-529dfd5df504","weight":1},{"event_id":4516,"event_guid":"d0768670-1b94-5a72-abbd-b481c5929ff3","weight":1},{"event_id":5252,"event_guid":"7805cae2-d664-441a-af87-555a2c5633a2","weight":1},{"event_id":5722,"event_guid":"906c5611-7e85-4593-8a4e-b33dedfce19e","weight":1},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":3},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":2},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":2},{"event_id":5743,"event_guid":"98f59651-b6ed-4428-9d9d-355873a8901d","weight":2},{"event_id":5747,"event_guid":"eb9f24f2-5094-4419-a806-ff7cfb432ed4","weight":1},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":2},{"event_id":5752,"event_guid":"75d71314-74b8-43c4-893f-c1ddb0cc050b","weight":2},{"event_id":5753,"event_guid":"0f675194-51f2-4165-9c6c-9b5653bc52e6","weight":2},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":2},{"event_id":5770,"event_guid":"2f8db0aa-c8e1-45c3-93fa-d5e4e7a0bb5d","weight":1},{"event_id":5771,"event_guid":"226378b4-80f1-4bd5-bf02-49ec5a3ac34c","weight":1},{"event_id":5774,"event_guid":"191e9835-4941-4f73-9c80-d453d684bb03","weight":1},{"event_id":5778,"event_guid":"c18d8138-d063-4f42-a5ba-d48c9e617714","weight":1},{"event_id":5781,"event_guid":"60b11faf-4afc-4c25-bae5-a59d48bda32a","weight":2},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":2},{"event_id":5791,"event_guid":"9144aaee-4cb6-4497-89d9-acca7da85730","weight":2},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":2},{"event_id":5796,"event_guid":"1098b55f-fe7c-4347-8f64-91b3d3c36322","weight":2},{"event_id":5799,"event_guid":"72e46e27-0667-4dca-bacd-128e55287e37","weight":1},{"event_id":5804,"event_guid":"e53c7455-bb5a-49f8-bc05-8b12887cb775","weight":1},{"event_id":5805,"event_guid":"8587bf27-b64f-4161-86a5-f77ee1735b3f","weight":1},{"event_id":5807,"event_guid":"d388bde4-a8b1-4caa-84fb-3f8a6e630afa","weight":1},{"event_id":5828,"event_guid":"b36d437f-7643-422d-b429-316a83826304","weight":1},{"event_id":5829,"event_guid":"9b34e4d2-533b-44ac-94c9-d53a70bc11a8","weight":3},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":2}]},{"guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","title":"CMake - Buildsystem und mehr","subtitle":null,"slug":"froscon2018-2167-cmake_-_buildsystem_und_mehr","link":"https://programm.froscon.de/2018/events/2167.html","description":"Immer mehr Projekte wechseln von GNU Autoconf/Automake zu CMake.\nWarum?

mission of the Apache Software Foundation (ASF) is to provide software for the public good. We do this by providing services and support for many like-minded software project communities of individuals who choose to join the ASF.\" \n\nThe ASF provides a home to several hundred OSS projects. Likely, if you are developing software on a daily basis you did run into one of those projects at some point in time. If you have been digging a bit deeper, you may have encountered the phrase \"The Apache Way\" - often used in relation to how projects at the ASF should work. Depending on who you ask, very likely you will get different answers as to what actual meaning of \"The Apache Way\" is.\n\nThis talk tries to give a glimpse behind the scenes - with a strong focus on what the implications of best practices advertised at the ASF are for downstream users of it's projects. \u003cspoiler\u003eIt's all about pulling you in to become active and contribute yourself\u003c/spoiler\u003e","original_language":"eng","persons":["Isabel Drost-Fromm"],"tags":["froscon2018","2119","Culture"],"view_count":41,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2024-05-18T01:30:02.099+02:00","length":2484,"duration":2484,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2119-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2119-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/60b11faf-4afc-4c25-bae5-a59d48bda32a-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/60b11faf-4afc-4c25-bae5-a59d48bda32a-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2119-the_apache_way","url":"https://api.media.ccc.de/public/events/60b11faf-4afc-4c25-bae5-a59d48bda32a","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":3998,"event_guid":"4DPy_rTjcx8v3-qpU0VcmQ","weight":1},{"event_id":5732,"event_guid":"e9fdf337-3b08-429c-a107-4a965cc4bb85","weight":5},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":8},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":4},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":5},{"event_id":5744,"event_guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","weight":5},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":5},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":5},{"event_id":5757,"event_guid":"fbec0a5a-7a3b-485d-8c50-e732dcea014f","weight":3},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":3},{"event_id":5759,"event_guid":"2285e54e-8774-48e5-9e77-6564149ee46b","weight":1},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":1},{"event_id":5765,"event_guid":"cc58e79c-5a9f-43cf-80da-6dca94b402c4","weight":1},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":4},{"event_id":5768,"event_guid":"cbec40e2-8dfa-46c0-b3ae-3a991876cad7","weight":4},{"event_id":5772,"event_guid":"d85ab00f-b631-4e1e-a930-329722774f40","weight":1},{"event_id":5779,"event_guid":"887c6067-774c-4ec3-a3bd-b888e137eec0","weight":3},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":4},{"event_id":5783,"event_guid":"61fc8330-6177-45d9-b644-18c0420422f0","weight":1},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":4},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":5},{"event_id":5799,"event_guid":"72e46e27-0667-4dca-bacd-128e55287e37","weight":3}]},{"guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","title":"L2/L3 für Fortgeschrittene - Helle und dunkle Magie im Linux-Netzwerkstack","subtitle":"Bridges, VLANs, vlan-aware-bridges, Bondage/LACP \u0026 Routingtabellen, PBR, VRFs, NetNS","slug":"froscon2018-2247-l2_l3_fur_fortgeschrittene_-_helle_und_dunkle_magie_im_linux-netzwerkstack","link":"https://programm.froscon.de/2018/events/2247.html","description":"Tag 2 startet mit dem zweiten Teil der Linux-Netzwerk-Grundlagen; es gibt noch einmal einen Ausflug durch die Layer 2 \u0026 3-Landschaft:\n\nDer Switch in meinem Linux-Rechner - was ist eine Bridge und wie benutze ich sie?

Sie wird heute in vielfältigsten Anwendungen eingesetzt - von dem kleinen, privaten Internetauftritt bis zu unternehmenskritischen Einsätzen wie bei Booking.com oder auch zahlreichen  DAX notierten Unternehmen in Deutschland. \nIm April 2018 hat Oracle sein neues Datenbankmanagementsystem MySQL 8.0 als Nachfolgeversion für die MySQL 5.7 freigegeben.\nDie größte Neuerung betrifft die Unterstützung für NoSQL Datenbanken auf Basis des neuen MySQL X-Protocols. Ab Version 8 kann MySQL somit auch als dokumentenbasierte Datenbank genutzt werden und tritt in Konkurrenz zu klassischen \"Document Store Datenbanken\" wie MongoDB.\n\nDas neue X-Protokoll  bietet eine Alternative zur klassischen SQL Abfrage die heutige Anforderungen einfacher und effektiver als herkömmliches SQL abbildet und Ihnen nativen Zugriff  via CRUD (Create, Read, Update, Delete) auf Ihre JSON Dokumente ermöglicht. Dadurch sind z.B. asynchrone Datenbankaufrufe und native Einbindung in JavaScript, Java, Python oder .NET möglich.\n\nIn diesem Vortrag werden wir beleuchten, welche Möglichkeiten sich dadurch ergeben und warum eine Alternative zum mächtigen SQL durchaus sinnvoll sein kann. Ebenso werden wir die neue MySQL Shell vorstellen, die dem Entwickler und DBA weit mehr Möglichkeiten bietet als das herkömmliche MySQL CLI.","original_language":"deu","persons":["ThalheimerC"],"tags":["froscon2018","2202","Databases"],"view_count":57,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2023-05-31T11:30:02.793+02:00","length":3924,"duration":3924,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2202-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2202-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/b72de5fc-3cd1-4a76-980c-ca48bac7184f-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/b72de5fc-3cd1-4a76-980c-ca48bac7184f-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2202-mysql_8_-_developing_next_generation_applications","url":"https://api.media.ccc.de/public/events/b72de5fc-3cd1-4a76-980c-ca48bac7184f","conference_title":"FrOSCon

We're already heading forward on that crossroad of privacy! We're developing pretty Easy privacy (pEp or p≡p) to make encryption easily available for everyone. \n\nWe've given up on the idea start protecting themselves, so we're writing protocols (and software) compatible with existing crypto and transport protocols. p≡p does what the user would want to do. This approach of taking away crypto needs from users’ view can be plugged into existing communication sofware. \n\n\np≡p motivates a new standard to securely encrypt and verify written communications without reinventing the wheel: p≡p eases secure communications relying on well-established end-to-end cryptographic methods by design. Following standards like OpenPGPG or OTR it integrates into existing systems for written digital communications and automating key management tasks. \n\np≡p's protocols automate the steps taught to users at cryptoparties, to protect their personal security and privacy by default. For easy integration of p≡p into application programming we provide very simple APIs because ultimately p≡p wants to change the default: from unencrypted, unverified and unanonymized to encrypted, verified and anonymized. \n\nWe support multiple platforms, multiple languages, multiple crypto technologies and multiple message transports. We will offer a Peer-to-Peer, End-to-End and device based secure synchronization of keys and configuration that is regularly audited Open Source and Free Software.\n","original_language":"eng","persons":["sva"],"tags":["froscon2018","2181","The crossroads of privacy"],"view_count":251,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-02-24T15:45:09.892+01:00","length":3533,"duration":3533,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2181-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2181-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/daa949b6-e0b2-4f4d-bd98-a9241f6d09c4-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/daa949b6-e0b2-4f4d-bd98-a9241f6d09c4-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2181-let_s_roll_out_mass_encryption","url":"https://api.media.ccc.de/public/events/daa949b6-e0b2-4f4d-bd98-a9241f6d09c4","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5010,"event_guid":"c34a07a2-0add-4809-bb25-280368b84db0","weight":7},{"event_id":5666,"event_guid":"05001d71-e22f-4bf5-9f0c-7105e719581a","weight":10},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":12},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":8},{"event_id":5748,"event_guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","weight":8},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":8},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":7},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":5},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":9},{"event_id":5769,"event_guid":"76ad2dd9-6054-44b4-a969-eb8f1bf87d62","weight":7},{"event_id":5772,"event_guid":"d85ab00f-b631-4e1e-a930-329722774f40","weight":7},{"event_id":5779,"event_guid":"887c6067-774c-4ec3-a3bd-b888e137eec0","weight":5},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":6},{"event_id":5789,"event_guid":"b4cb8731-0709-4c3e-967b-3766a15ea572","weight":8},{"event_id":5790,"event_guid":"f9c7f1a4-a696-4559-9d65-52e770591c38","weight":9},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":7},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":3},{"event_id":5795,"event_guid":"d3821dc9-94af-438a-af6a-d4f79df43a2f","weight":9},{"event_id":5811,"event_guid":"b9affdeb-41c2-4322-8a5a-1c7676372ea9","weight":8},{"event_id":5816,"event_guid":"4a6584de-59fd-405e-be42-ce295cc516f2","weight":6},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":3},{"event_id":5822,"event_guid":"92d1bc03-3224-4dc6-be3a-691e96d641fb","weight":7},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":9}]},{"guid":"7bd7470f-6197-4356-abb3-73d123f49c87","title":"Deep Dive TypeScript und ein Ausblick in die Zukunft","subtitle":null,"slug":"froscon2018-2132-deep_dive_typescript_und_ein_ausblick_in_die_zukunft","link":"https://programm.froscon.de/2018/events/2132.html","description":"Die Sprache TypeScript hatte es sich zum Ziel gesetzt, die Entwicklung von Web-Anwendungen deutlich zu vereinfachen.

This talk is going to present MapOSMatic, a service that produces large scale single and multi page high resolution maps.\n\nMapOSMatic produces large scale maps in PDF, SVG or high resolution PNG format. Map data from OpenStreetMap is rendered using customizable style sheets, and optionally combined with extra textual information, like a street index for the visible area.

Teilweise wird sogar von führenden Experten empfohlen IPv6 abzuschalten \"weil das nur Probleme macht\". Warum das nicht so ist, und warum man sich doch auf die \"neue\" Welt einlassen sollte erklärt dieser praxisorientierte Vortrag.\n\nDer Vortag führt ein in Adresskonzepte, Adressvergabe und -auflösung (SLAAC, DHCPv6, DHCPv6-PD, ND, RDNSS, etc.) und zeigt einen typischen Adressierunsplan auf. Brückentechnologien wie NAT64, DS-lite und Teredo werden vorgestellt und eingeordnet. Die Konfiguration von IPv6 unter Linux wird am Beispiel von iproute2 bzw. Debian Netzwerkkonfiguration sowie sysctls aufgezeigt.","original_language":"deu","persons":["Falk Stern","Maximilian Wilhelm"],"tags":["froscon2018","2242","Network

quickly growing smart home market, the industry has come up with a vast number of standards, protocols and products. Be it Apple HomeKit, Amazon Echo or Google Home, they usually don't play well together and there is hardly any interoperability across vendors. What is more, the only thing they connect to is their respective cloud service, which lets a typical smart home depend on dozens of remote servers - clearly not a desirable setup as it affects reliability, latency, data privacy, longevity and more.\n\nThe openHAB project has attracted a huge developer community, which looks at the smart home from a user perspective: This makes features like offline capability, data privacy and customisability top priorities for a smart home solution.

Aus diesem Bedürfnis sind eine Reihe Automatisierungs- und Konfigurationsmanagementtools entstanden. Unter anderem auch Ansible, das bereits in vielen Projekten Verwendung findet.\nAnsibles KISS-Prinzip lädt dazu ein, bereits einfache Aufgaben wie Filetransfers, Paketinstallationen und das Verwalten von Services darüber abzuwickeln. Viele Playbooks/Rollen überschreiten diesen Grad an Komplexität nicht. Die Mächtigkeit von Ansible durch die Plugin-Infrastruktur und die verwendete Templating Engine Jinja2 geht darüber noch deutlich hinaus. So lassen z.B. sich komplexe Schleifen über Objekte realisieren, Inventories aus bestehenden Infrastrukturverwaltungen wie Foreman/Katello oder Docker generieren, mit ansible-pull das aktuelle Playbook aus einem git Repository runterladen und ausführen, verschlüsselte Variablen und Dateien erst zur Laufzeit entschlüsseln oder ganze Playbooks mit Ansible generieren. In diesem Vortrag werden ein paar ausgewählte über die Grundlagen hinausgehenden Möglichkeiten und Anwendungsfälle von Ansible beleuchtet.","original_language":"deu","persons":["Manuel Bonk"],"tags":["froscon2018","2130","System Administration"],"view_count":628,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-07-03T10:45:03.733+02:00","length":2030,"duration":2030,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2130-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2130-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/e7828a90-6f0a-439b-a6a8-2e129a00b521-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/e7828a90-6f0a-439b-a6a8-2e129a00b521-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2130-next_level_ansible","url":"https://api.media.ccc.de/public/events/e7828a90-6f0a-439b-a6a8-2e129a00b521","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":3085,"event_guid":"fe349b93-6f5a-4964-83d0-d9f5c65bb68e","weight":17},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":42},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":17},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":41},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":37},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":37},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":25},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":105},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":23},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":20},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":28},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":16},{"event_id":5788,"event_guid":"b6faaa05-454e-4a52-9cbe-4e52bd30ad80","weight":27},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":25},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":18},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":21},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":40}]},{"guid":"ad920111-8443-4cde-9184-c94aa42a41db","title":"Apache Kafka: Lessons learned","subtitle":"Apache Kafka kann manchmal positiv und negativ überraschen.

Federführend von MEP Axel Voss begleitet droht die europäische Urheberrechtsreform Open Source und Internetkultur zu zerstören. Was läuft schief in Brüssel?\n\nAuf Initiative der EU-Kommission wird in der Europäischen Union eine Reform des Urheberrechts vorangetrieben. Ein Knackpunkt ist die geplante Einführung von Upload-Filtern für alle Plattformen, auf denen\nnutzergenerierte Inhalte vorkommen. Urheberrechtsverletzungen sollen online im Vornheerin verhindert werden. Werden geschützte Inhalte erkannt, wird ein (neu)upload verhindert. Software, die auf Open Source basiert, kann dieses Blocking ebenso auslösen wie ein Meme, das von einem Menschen niemals als Rechte und Interessen des Rechteinhabers erkannt worden wäre. Filter produzieren reihenweise Fehler, von denen nicht nur GitHub und die Open Source Community akut bedroht sind.

What this will trigger is building a docker image using the running docker engine on your host. \nThe problems start at a point where you don't have access to the docker daemon, want to build a container in a container (as most CI systems execute in containers nowadays) or just have limited permissions on the system. \n\nFor this we will open the mystical box of a docker image by looking into:\n- Layers\n- Empty Layers\n- Configuration Details\n\nThen we will look into the kaniko project that tries to build those images without ever touching a docker daemon to better understand how those images can be created and how to work in more restricted environments. \n\nThose information can also be very helpful when looking into container security and scanning what is in the box.

In Zeiten von interdisziplinärer Biomedizin, eHealth und Data Science benötigen Mediziner mehr denn je breit angelegte Unterstützung um gezielt Entscheidungen im Sinne des Patienten zu treffen. Hierfür ist es nicht nur wichtig, von Anfang an gegen den Eindruck einer digitalen Bevormundung zu arbeiten, sondern auch, solche Prozesse transparent zu gestalten. Dazu kann und sollte Open Source Software Schlüssel sein.\n\nIn klinischen Szenarios steht der letztendlichen Behandlungsentscheidung eine möglichst detaillierten Diagnose vor. Diese umfasst üblicherweise Gespräche (Anamnese), physische Tests sowie Laboruntersuchungen. Die Gesamtheit dieser Informationen verstehen sich als Eingabeparameter eines komplexen Algorithmus. Zentrale Elemente sind dabei die Leitlinien der Fachgesellschaften sowie der persönliche Erfahrungsschatz des Arztes selbst. Leitlinien stellen die Essenz dessen dar, was anhand von empirisch zusammengetragenen Erkenntnissen als zum aktuellen Stand der Forschung als gesichert angenommen werden kann – im Englischen als „Evidence-based Medicine“ bezeichnet. Zentrale Werkzeuge sind dabei Publikationen nach wissenschaftlichem Standard sowie klinische Studien, die Erkenntnisse mit einer statistischen Signifikanz auszeichnen können. Algorithmisch betrachtet stellen sich Leitlinien eher regelartig, star und generell dar; komplementär dazu agiert der Arzt analog zu unscharfen Verfahren wie neuronalen Netzen eher individuell und weniger explizit. \n\nAllerdings stellt für den Arzt selbst allein das immense Wachstum an verfügbarer medizinischer Fachliteratur heutzutage ein praktisches Problem dar. Gleichzeitig geht der Trend in der modernen Medizin dazu, Patienten individueller zu betrachten: stratifiziert in Subgruppen bis hin zur personalisierten Einzelfallbetrachtung. Während diese Verkleinerung der Kohorten bereits per Definition die statistische Signifikanz im Behandlungskontext schwächt, steigt die Erwartungshaltung an den behandelnden Arzt, eine im Sinne des Patienten optimale und begründbare Entscheidung zu treffen. Hinzu kommen abstrakte Massendaten aus hochmodernen Disziplinen wie der Genomik.\n\nIn der Summe benötigt der „Algorithmus“ zur Entscheidungsfindung neben Erfahrungen und Leitlinien Erweiterungen, die medizinisches Fachpersonal in Routineversorgung und auch klinischer Forschung unterstützen. Eine gezielte Integration von öffentlich verfügbarem Wissen und  Massendaten geht dabei über die derzeit an Kliniken etablierten, meist proprietären Software-Lösungen weit hinaus. Im Vortrag soll daher ein Überblick zunächst über den Status Quo, die derzeitigen und bevorstehenden Herausforderungen sowie potenzielle Lösungswege gegeben werden. Neben einer massiven Unterschätzung der benötigten Ressourcen zur Etablierung von Lösung stellen der Umgang mit Datenschutz sowie Transparenz und Reproduzierbarkeit häufig ignorierte Problemstellungen dar. Diese treten sowohl in Routine und Forschung auf, vor allem aber an deren Berührungspunkten.\n\nDer Vortrag soll Perspektiven aufzuzeigen, wie gerade im sensiblen Umfeld der Klinik Open Source Türen öffnen und solide Basis wissenschaftlicher Arbeit werden kann. Dabei sollen exemplarische Workflows vorgestellt werden, die Ärzte teilautomatisiert in ihren Entscheidungen ausdrücklich unterstützen. Da Vertrauen in neue Verfahren eng mit Transparenz einhergeht, sollen deren zugrunde liegenden Prinzipien anhand der vorgestellten Verfahren aufgezeigt werden. Abschließend wird ein Ausblick auf eine mögliche moderne, hochintegrative Biomedizin gegeben.","original_language":"deu","persons":["Sebastian Schaaf"],"tags":["froscon2018","2218","Blessed by the algorithm"],"view_count":88,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2024-05-23T20:30:03.592+02:00","length":3299,"duration":3299,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2218-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2218-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/9b34e4d2-533b-44ac-94c9-d53a70bc11a8-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/9b34e4d2-533b-44ac-94c9-d53a70bc11a8-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2218-don_t_scroll_-_entscheidungsunterstutzung_im_biomedizinischen_bereich_jenseits_von_excel","url":"https://api.media.ccc.de/public/events/9b34e4d2-533b-44ac-94c9-d53a70bc11a8","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":1057,"event_guid":"import-d93f6f776ff5e0bf3d","weight":2},{"event_id":5735,"event_guid":"d494138e-2442-4b08-b06b-43e1aa444701","weight":3},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":4},{"event_id":5743,"event_guid":"98f59651-b6ed-4428-9d9d-355873a8901d","weight":4},{"event_id":5749,"event_guid":"659ad4fe-93cd-4cb9-a273-7956b96ab02f","weight":3},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":5},{"event_id":5752,"event_guid":"75d71314-74b8-43c4-893f-c1ddb0cc050b","weight":4},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":3},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":3},{"event_id":5774,"event_guid":"191e9835-4941-4f73-9c80-d453d684bb03","weight":3},{"event_id":5781,"event_guid":"60b11faf-4afc-4c25-bae5-a59d48bda32a","weight":3},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":3},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":3},{"event_id":5805,"event_guid":"8587bf27-b64f-4161-86a5-f77ee1735b3f","weight":2},{"event_id":5807,"event_guid":"d388bde4-a8b1-4caa-84fb-3f8a6e630afa","weight":2},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":3},{"event_id":5824,"event_guid":"0a8b729c-ebe9-48f3-a30a-7b422fccbc0d","weight":3},{"event_id":5825,"event_guid":"d535dfae-c59a-4a72-9d86-94e3ce66e549","weight":1},{"event_id":5827,"event_guid":"652fdd40-d2a0-4955-b2a3-d268d7c53884","weight":1},{"event_id":5828,"event_guid":"b36d437f-7643-422d-b429-316a83826304","weight":2},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":9},{"event_id":5831,"event_guid":"5fa9fb17-3bb5-43c2-9ef9-3ed9db1c957a","weight":4}]},{"guid":"ddcadb48-0ea6-4bbd-8823-57b70e394afc","title":"Dynamische Routingprotokolle Aufzucht und Pflege - OSPF","subtitle":null,"slug":"froscon2018-2243-dynamische_routingprotokolle_aufzucht_und_pflege_-_ospf","link":"https://programm.froscon.de/2018/events/2243.html","description":"Herzlichen Glückwunsch!

Ein grundlegendes Wissen der Speicherabläufe während des Programmlaufs helfen hier aber ein besseres und sicheres Programmieren im nebenläufigen Umfeld zu gewährleisten. Exemplarisch wird dies mit Java auf der JVM erklärt.\n\nSeit sich Multicore-Prozessoren immer mehr verbreiten haben, hat auch das Augenmerk auf die nebenläufige Programmierung ebenfalls stark zugenommen. Und nicht erst seit der neuen Concurrency API in Java 8 oder der Reactive Streams Bibliotheken bietet Java die Möglichkeit der nebenläufigen Programmierung.\n\nNebenläufigkeit ist dabei aber nicht immer intuitiv und gemeinsam genutzte Ressourcen sind nicht auf den ersten Blick ersichtlich. Hier lauern selbst mit modernen Konstrukten wie Threadpools, Futures und Promises immer die Gefahr der Race Conditions, Dead Locks und Starvation. Fehler, welche meist erst nach einiger Zeit in Produktion und bei entsprechender Last auftreten und das Finden und Beheben zu einer stundenlangen Tortour ausarten lassen.\n\nEs hilft daher Fallstricke und mögliche Fehlerfälle von Nebenläufigkeiten im Vorfeld zu kennen und zu vermeiden. Hierbei kann einem ein grundlegendes Verständnis von Speichermodellen und deren Abläufen helfen, wobei Java hier mit dem Java Memory Modell eine Abstraktion über die vielfältigen Rechnerachitekturen bietet. \nDer Talk gibt zunächst einen Einblick in das Java Memory Modell als Abstraktion und die grundlegenden Funktionsweisen eines Speichermodells im parallelen Betrieb. Es werden die Operationen 'flush' und 'pull' eingeführt, womit einzelne Threads ihren lokalen Cache mit dem Hauptspeicher synchronisieren.\n\nMit Beispielen wird gezeigt, wie die Probleme der Atomicity, des Reordering und der Sequential Consistency durch die Mechanismen des Speichermodells auftreten können und welche Implikationen dies im Betrieb hat. \n\nIm Anschluss werden Patterns gezeigt, womit einige dieser Probleme vermieden werden können. Wo Patterns nicht greifen, werden die Javamechanismen 'final Variablen', „volatile Variablen“ und „sychronize“ gezeigt und welchen Einfluss diese Mechanismen auf das Speichermodell haben. Zum Schluss wird ein kleiner Auszug aus der Concurrency Library gezeigt, welche die Patterns und auch die spracheigenene Mechanismen unterstützen.","original_language":"deu","persons":["Christian Iwanzik"],"tags":["froscon2018","2176","Development"],"view_count":171,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2025-06-19T19:30:04.981+02:00","length":3289,"duration":3289,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2176-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2176-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/cc58e79c-5a9f-43cf-80da-6dca94b402c4-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/cc58e79c-5a9f-43cf-80da-6dca94b402c4-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2176-unter_der_haube_der_jvm","url":"https://api.media.ccc.de/public/events/cc58e79c-5a9f-43cf-80da-6dca94b402c4","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":3998,"event_guid":"4DPy_rTjcx8v3-qpU0VcmQ","weight":1},{"event_id":4433,"event_guid":"dc9b4e9a-edc3-473a-bfde-81fd30604b81","weight":4},{"event_id":5065,"event_guid":"b13b7d07-a781-4777-ac11-c331a204e710","weight":2},{"event_id":5732,"event_guid":"e9fdf337-3b08-429c-a107-4a965cc4bb85","weight":1},{"event_id":5734,"event_guid":"adde2800-ffa1-44c4-aafd-c4928ee5378d","weight":7},{"event_id":5736,"event_guid":"73bbeee4-7791-42d2-b3bd-317ca12a8895","weight":1},{"event_id":5738,"event_guid":"fafacf91-9842-4a5f-bb02-146250450001","weight":5},{"event_id":5741,"event_guid":"99b060b6-4207-40a3-9b6a-da340b8f0403","weight":1},{"event_id":5742,"event_guid":"7bd7470f-6197-4356-abb3-73d123f49c87","weight":4},{"event_id":5744,"event_guid":"7f4d46f0-83bd-4551-bb55-1b558ba59dda","weight":2},{"event_id":5746,"event_guid":"ad920111-8443-4cde-9184-c94aa42a41db","weight":2},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":1},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":4},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":1},{"event_id":5757,"event_guid":"fbec0a5a-7a3b-485d-8c50-e732dcea014f","weight":5},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":1},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":1},{"event_id":5767,"event_guid":"dbb0c6bc-d14f-4d9b-9c9e-f66fa0143721","weight":4},{"event_id":5769,"event_guid":"76ad2dd9-6054-44b4-a969-eb8f1bf87d62","weight":5},{"event_id":5772,"event_guid":"d85ab00f-b631-4e1e-a930-329722774f40","weight":6},{"event_id":5778,"event_guid":"c18d8138-d063-4f42-a5ba-d48c9e617714","weight":5},{"event_id":5780,"event_guid":"62e8df5f-cd0b-4606-8d61-18b274e1d048","weight":2},{"event_id":5781,"event_guid":"60b11faf-4afc-4c25-bae5-a59d48bda32a","weight":1},{"event_id":5782,"event_guid":"2596a0ad-f2a4-403b-9d79-1398c4f72e53","weight":1},{"event_id":5783,"event_guid":"61fc8330-6177-45d9-b644-18c0420422f0","weight":1},{"event_id":5819,"event_guid":"4fd19ecd-d015-4329-b825-cd7bc6541674","weight":4},{"event_id":5820,"event_guid":"d285cec6-c1b3-41bc-bb28-ed499609bd2e","weight":6},{"event_id":5830,"event_guid":"1f3a0237-0515-4cdb-90ac-d57f7bc85586","weight":4}]},{"guid":"d3821dc9-94af-438a-af6a-d4f79df43a2f","title":"Turris: secure open source router","subtitle":"Who is the root on your router?","slug":"froscon2018-2104-turris_secure_open_source_router","link":"https://programm.froscon.de/2018/events/2104.html","description":"At CZ.NIC we are making open source Turris routers.

So what cool open source projects did we integrated and how?\n\nThe talk with describe how do we do stuff, what challenges do we face in regards to having self-updating router that people can and thinker with and then we go into details of some really nice security features that we integrated and made really easy for people to use.","original_language":"eng","persons":["Michal Hrusecky"],"tags":["froscon2018","2104","Security"],"view_count":146,"promoted":false,"date":"2018-08-26T00:00:00.000+02:00","release_date":"2018-08-26T02:00:00.000+02:00","updated_at":"2025-06-20T21:45:05.706+02:00","length":3150,"duration":3150,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2104-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2104-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/d3821dc9-94af-438a-af6a-d4f79df43a2f-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/d3821dc9-94af-438a-af6a-d4f79df43a2f-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2104-turris_secure_open_source_router","url":"https://api.media.ccc.de/public/events/d3821dc9-94af-438a-af6a-d4f79df43a2f","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":9},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":7},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":7},{"event_id":5761,"event_guid":"eff9b1c1-1e6b-445f-b153-a0b4a4e58b67","weight":6},{"event_id":5763,"event_guid":"e7828a90-6f0a-439b-a6a8-2e129a00b521","weight":6},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":7},{"event_id":5775,"event_guid":"8c0b8e5b-7e38-486a-bd97-5329857ffae8","weight":6},{"event_id":5787,"event_guid":"4a080f4f-ec05-4c7a-990d-fa26c6227ab5","weight":6},{"event_id":5790,"event_guid":"f9c7f1a4-a696-4559-9d65-52e770591c38","weight":7},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":10},{"event_id":5793,"event_guid":"05d2f707-19a8-491d-a375-13280c771034","weight":7},{"event_id":5794,"event_guid":"1963b747-4067-4b34-9c45-debd2f020fef","weight":11},{"event_id":5808,"event_guid":"daa949b6-e0b2-4f4d-bd98-a9241f6d09c4","weight":9},{"event_id":5810,"event_guid":"291fe17d-80ca-46a9-9978-c61509a4f9c9","weight":6},{"event_id":5811,"event_guid":"b9affdeb-41c2-4322-8a5a-1c7676372ea9","weight":5}]},{"guid":"191e9835-4941-4f73-9c80-d453d684bb03","title":"FAIR Data Prinzipien, Transparenz und Reproduzierbarkeit im Kontext von Open Source Software in den Wissenschaften","subtitle":"FAIR Data Prinzipien, Transparenz und Reproduzierbarkeit im Kontext von Open Source Software in den Wissenschaften: Quo vaditis?","slug":"froscon2018-2157-fair_data_prinzipien_transparenz_und_reproduzierbarkeit_im_kontext_von_open_source_software_in_den_wissenschaften","link":"https://programm.froscon.de/2018/events/2157.html","description":"Die Nutzung von Open Source ist ein guter Ansatz um zentrale ethische Maßstäbe in der Wissenschaft einfacher zur Anwendung zu bringen: Reproduzierbarkeit, Transparenz und der faire und wenn möglich offene Umgang mit Daten, kurz der „FAIR Data“ Prinzipien [1]. Der Vortrag soll den Status Quo in der Mathematik, Informatik und den Lebenswissenschaften sowie einiger Geisteswissenschaften darstellen und würdigen.  Als Beispiel für Spannungsfelder in der interdisziplinären Forschung stellen wir die Open Source-Strategie der Arbeitsgruppe Bioinformatik am Fraunhofer SCAI vor. \n\nVerschiedene Fachgruppen haben verschiedene Fachtraditionen, stehen aber zu den selben ethischen Grundwerten des wissenschaftlichen Arbeitens. Ist der Umgang mit Open Source Software in der Mathematik und Informatik noch relativ gebräuchlich, setzen Geisteswissenschaftler eher auf kommerzielle Softwarelösungen. Hier zeigt sich der Verlauf von allgemeineren zu spezifischeren Fachanwendungen. Wird in der Informatik primär programmiert, ist schon die Mathematik spezieller. Das zeigt sich am Einsatz von Software wie Matlab, Octave oder R. Auch in anderen Bereichen wie den Lebenswissenschaften zeigt sich eine Bandbreite von hochspezialisierten, recht statischen Fachanwendungen, zum Beispiel für die Mikroskopie, bis hin zu Lösungen in generischen Umgebungen wie R oder Python. In der Welt der Geisteswissenschaften findet Open Source wiederum wenig Beachtung. \n\nAm Beispiel verschiedener wissenschaftlicher Disziplinen möchten wir zum einen die Diskrepanz zwischen allgemeinen und spezifischen Softwarelösungen sowie Probleme beim Einsatz von Open Source diskutieren. Zum anderen möchten wir die Anwendung der FAIR Data Prinzipien [1] in den wissenschaftlichen Disziplinen darstellen und diskutieren. In diesem Spannungsfeld findet sich die Open Source Software – kein Garant, aber eine gute Chance, sowohl in den spezifischen als auch allgemeinen Anforderungen von FAIR Data zu leben.\n\nAnhand der Open-Source-Strategie der Arbeitsgruppe Bioinformatik möchten wir auf die Besonderheiten  interdisziplinärer Arbeit eingehen, praktische und fachkulturelle Probleme sowie ihre Lösungen benennen und diskutieren. Manche Daten unserer Projekte sind nicht frei verfügbar, manche Software durfte aus lizenzrechtlichen Gründen nicht zur Verfügung gestellt werden. Trotz oder gerade deswegen glauben wir jedoch, dass die Vorteile bei der Nutzung von Open Source in der Wissenschaft überwiegen. Für ein Umdenken muss aktiv geworben und gearbeitet werden. \n\n\nLiteratur\n[1] Wilkinson, Mark D., et al. \"The FAIR Guiding Principles for scientific data management and stewardship.\" Scientific data 3 (2016).","original_language":"deu","persons":["Jens Dörpinghaus"],"tags":["froscon2018","2157","FrOSCon meets Science"],"view_count":86,"promoted":false,"date":"2018-08-25T00:00:00.000+02:00","release_date":"2018-08-25T02:00:00.000+02:00","updated_at":"2024-01-29T15:45:03.600+01:00","length":2951,"duration":2951,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2018/2157-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2018/2157-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2018/191e9835-4941-4f73-9c80-d453d684bb03-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2018/191e9835-4941-4f73-9c80-d453d684bb03-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2018-2157-fair_data_prinzipien_transparenz_und_reproduzierbarkeit_im_kontext_von_open_source_software_in_den_wissenschaften","url":"https://api.media.ccc.de/public/events/191e9835-4941-4f73-9c80-d453d684bb03","conference_title":"FrOSCon 2018","conference_url":"https://api.media.ccc.de/public/conferences/froscon2018","related":[{"event_id":4538,"event_guid":"41484e52-4847-2020-2020-202020202020","weight":1},{"event_id":4946,"event_guid":"64be895b-faa3-5543-b6e0-06cf4b361229","weight":1},{"event_id":4947,"event_guid":"42a13e11-7a59-5234-94d7-45327616e6b2","weight":1},{"event_id":4948,"event_guid":"61044a55-e6d6-4b9c-add9-a7f07c65da70","weight":1},{"event_id":5743,"event_guid":"98f59651-b6ed-4428-9d9d-355873a8901d","weight":3},{"event_id":5748,"event_guid":"459955f6-2c2f-46ce-8ab7-ca02f350c9d2","weight":1},{"event_id":5751,"event_guid":"2b7d1c38-d3e0-4978-ac30-95aed9e7b0d7","weight":2},{"event_id":5752,"event_guid":"75d71314-74b8-43c4-893f-c1ddb0cc050b","weight":2},{"event_id":5753,"event_guid":"0f675194-51f2-4165-9c6c-9b5653bc52e6","weight":1},{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":1},{"event_id":5756,"event_guid":"cfc15b5d-d114-447d-a351-7d17fcf05869","weight":3},{"event_id":5773,"event_guid":"be056c9c-b6f6-42a3-adb1-0d6e80a1f4c7","weight":1},{"event_id":5784,"event_guid":"065821fd-67da-4565-a380-a6a9d403416e","weight":1},{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":2},{"event_id":5793,"event_guid":"05d2f707-19a8-491d-a375-13280c771034","weight":2},{"event_id":5796,"event_guid":"1098b55f-fe7c-4347-8f64-91b3d3c36322","weight":2},{"event_id":5799,"event_guid":"72e46e27-0667-4dca-bacd-128e55287e37","weight":3},{"event_id":5805,"event_guid":"8587bf27-b64f-4161-86a5-f77ee1735b3f","weight":2},{"event_id":5814,"event_guid":"35fdf9d0-bb63-484e-9309-cc2a07073ca7","weight":1},{"event_id":5815,"event_guid":"049bf950-ff7a-4d68-b658-66f611cbdfd7","weight":1},{"event_id":5829,"event_guid":"9b34e4d2-533b-44ac-94c9-d53a70bc11a8","weight":3}]},{"guid":"35fdf9d0-bb63-484e-9309-cc2a07073ca7","title":"Patch Rejected","subtitle":"12 Gründe, warum ein Patch nicht angenommen wird und wie man sie vermeidet","slug":"froscon2018-2203-patch_rejected","link":"https://programm.froscon.de/2018/events/2203.html","description":"Der Vortrag vermittelt einen grundlegenden Überblick darüber, wie man einen Patch in ein Open-Source-Projekt einbringt, welche Vorarbeiten nötig sind und welche Gründe es dafür geben kann,  \ndass ein Patch von einem Projekt möglicherweise nicht angenommen wird.
