Auf teilweise legendärer Hardware spielte man nächtelang coole Spiele. Nur leider sind meist die alten Computer im Laufe der Zeit abhanden gekommen oder funktionieren nicht mehr.\n\nDer Vortrag erklärt, wie man sich mithilfe entsprechender Emulatoren auf moderner Hardware die Stimmung der 80er und 90er zurückholen kann.\n\nWer kennt sie noch, die Ataris, C64, KCs oder ZX81? Oder auch diese ganzen „altmodischen“ Spielekonsolen, welche feierlich an den Fernseher angeschlossen wurden? Aber sicherlich kennt jeder noch, ein gewisses Lebensalter vorausgesetzt, sein Lieblingsspiel, welches er nächtelang, auf dieser „komischen“ Hardware gezockt hat!\n\nWie schön wäre es doch, einfach diese Kiste wieder einzuschalten, den Joystick in die Hand zu nehmen und das liebgewonnene Run-and Jump-Spiel, mit seiner eintönigen Soundausgabe, zu starten? Bloß leider ist die alte Hardware beim letzten Umzug abhanden gekommen oder kaputt gegangen (hat da nicht sogar der Lebenspartner nachgeholfen?)...\n\nKein Problem! Mit der richtigen Software (Emulatoren) auf modernen Rechnern (PC und/oder Raspberry Pi), kann man die 80er und 90er Jahre wieder auf seinen Monitor zaubern. Im Rahmen des Vortrages soll gezeigt werden, wie man das macht, was man dazu braucht und auch, welche rechtlichen Aspekte zu beachten sind. Sicherlich wird auch noch Zeit sein, das eine oder andere Retro-Projekt des Referenten kurz anzusprechen.","original_language":"deu","persons":["Uwe Berger"],"tags":["froscon2019","2397","other"],"view_count":223,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2024-09-17T17:00:02.492+02:00","length":4285,"duration":4285,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2397-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2397-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2397-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2397-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2397-retrogaming_und_-computing","url":"https://api.media.ccc.de/public/events/3f274d3f-db32-4687-95e7-ce5dcf866bee","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":11},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":5},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":6},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":7},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":11},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":7},{"event_id":7292,"event_guid":"b3ebf68d-8a2a-4564-ab24-e013dc92ba1c","weight":1},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":6},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":18},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":14},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":8},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":10},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":10},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":9},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":11},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":11},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":8}]},{"guid":"84aca65d-603a-4fc1-844e-061cdeb14f71","title":"shutdown","subtitle":null,"slug":"froscon2019-2515-shutdown","link":"https://programm.froscon.de/2019/events/2515.html","description":null,"original_language":"deu","persons":["ScottyTM","Boernd"],"tags":["froscon2019","2515","other"],"view_count":173,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2024-08-19T10:15:03.024+02:00","length":602,"duration":602,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2515-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2515-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2515-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2515-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2515-shutdown","url":"https://api.media.ccc.de/public/events/84aca65d-603a-4fc1-844e-061cdeb14f71","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":12},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":8},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":7},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":8},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":7},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":2},{"event_id":7325,"event_guid":"9279d4b2-71f4-4b6a-8b65-d40cdeb75b1a","weight":9},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":15},{"event_id":7336,"event_guid":"0ef5f8b9-03f7-484b-9659-f754e8261910","weight":8},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":22},{"event_id":7355,"event_guid":"a160f9d4-663b-4237-b56a-20d065ade180","weight":5},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":8}]},{"guid":"f4c595e4-f4df-4952-aab3-c40f38583a79","title":"Die intelligente Fußbodenheizung","subtitle":"IoT, Cloud und KI – was will man mehr","slug":"froscon2019-2430-die_intelligente_fussbodenheizung","link":"https://programm.froscon.de/2019/events/2430.html","description":"Zu kalt zu warm zu kalt zu warm. Erst braucht sie ewig, dann heizt sie viel zu lange nach. Zudem sind herkömmlichen Steuerungen nicht sehr energieeffizient.\n\nDas muss doch intelligenter gehen, ohne sich zum Datenlieferant der bekannten Anbieter zu machen, dachten Wido und Holger. Das OpenSource-Projekt „smart underfloorheating“ war geboren. Ein Arduino-Mikrocontroller steuert das Ventil und funkt Sensordaten an das Backend (Azure). Die KI-Engine in R sorgt für eine sich verbessernde Steuerung, die den Wunsch-Temperaturverlauf der Nutzerin umzusetzen versucht. Beim Design der Lösung wird Wert auf Offenheit, Vielseitigkeit und Erweiterbarkeit der Anwendung gelegt.\n\nWürde man meine Fußbodenheizung mit einem Schiff vergleichen, dann am ehesten mit einem großen Öltanker der immer viel Zeit zum Anlaufen braucht und dann kaum zu stoppen ist. Erst braucht sie ewig, dann heizt sie viel zu lange nach.\n\nDas muss doch intelligenter gehen ohne sich zum Datenlieferant der bekannten Anbieter zu machen. Das OpenSource-Projekt „smart underfloorheating“ von Wido und Holger war geboren.\n\nIn den aktuellen Zeiten, in denen das Einsparen von klimaschädlichen Emissionen drastisch wichtiger wird, sollten alle Bereiche in denen Einsparpotentiale liegen angegangen werden. Auch ohne genaue Evaluationen herangezogen zu haben ist offensichtlich, dass bei herkömmlichen Thermostaten große Sparpotenziale schlummern. Hier will dieses Projekt unter Mithilfe möglichst vieler engagierter Bürger*innen ansetzen und Verbesserungen erzielen. Die Erkenntnisse der Community können in weiteren Projekten – kommerziell oder offen – weiterverwendet werden.\n\nFußbodenheizungssteuerung klingt ja nicht gerade sexy. Aber in dem Projekt vereinen wir verschiedene zur Zeit sehr angesagte Bereiche. Da wären die Mikrocontroller-Programmierung und Lötarbeiten, die Datenbank ggf. in der Cloud als zentraler Datenspeicher und obendrauf können wir uns noch an maschinellem Lernen versuchen, um eine intelligente Steuerung zu erreichen.\n\nUnser OpenSource-Projekt „smart underfloorheating“ besteht aus mehreren Modulen, die unabhängig weiterentwickelt werden können und per APIs miteinander kommunizieren:\n\u003col\u003e\n \t\u003cli\u003eDas smarte Thermostat\u003c/li\u003e\n \t\u003cli\u003eDas Backend in der Cloud\u003c/li\u003e\n \t\u003cli\u003eWeitere Sensoren und Webservices (z. B.Wetterdienst)\u003c/li\u003e\n \t\u003cli\u003eDie KI-Engine in R\u003c/li\u003e\n \t\u003cli\u003eDas Nutzer-Interface\u003c/li\u003e\n\u003c/ol\u003e\n\u003cstrong\u003eDie Architektur / das Zusammenspiel der verschiedenen Module\u003c/strong\u003e\n\nDie angestrebte Lösung soll kein zentrales System zum Ziel haben, sondern versteht sich als modulares Projekt, an dem viele Interessierte mitwirken können und sollen. Wir möchten eine Beispielimplementierung umsetzen und betreiben, bei der jede und jeder mitmachen kann. Da hier verschiedene Techniken zusammenspielen, ist ein modularer Aufbau mit wohldefinierten Schnittstellen wichtig. Dadurch wird gewährleistet, dass eigene Implementierungen einzelner Komponenten: IoT Device, Backend, KI-Engine entwickelt werden können, ohne die anderen Bereiche ändern zu müssen.\n\n\u003cstrong\u003eDas smarte Thermostat\u003c/strong\u003e\n\nDas Thermostat basiert auf einem Microcontroller, welcher mit dem Backend über eine Web-API verbunden ist. Temperaturwerte werden regelmäßig gesendet und Aktualisierungen vom Backend empfangen. Das Thermostat kann sich in verschiedenen Modi befinden. Abhängig von diesen agiert es unterschiedlich und empfängt die passenden Instruktionen/Programme vom Backend. Die Hauptaufgabe ist es das Heizungsventil zu öffnen und zu schließen. Ein kleines Display zeigt Temperatur und Zustände an. Über einen Drehknopf kann die Wunschtemperatur auch am Thermostat eingestellt werden.\n\n\u003cstrong\u003eDas Backend\u003c/strong\u003e\n\nDas Backend Speicherort der Sensor- und weiterer Daten. Es ist die Schaltzentrale, welche die Kommunikation zwischen den Modulen koordiniert. D.h. das Backend sorgt dafür, dass das vom Nutzer-Interface den gewünschten Temperaturverlauf in der Datenbank gespeichert wird und der KI-Engine zur Verfügung stellt. Zudem werden alle Sensordaten in einer Tabelle zusammengeführt. Die KI-Engine wiederum holt sich alle benötigten Daten ab und schreibt das Steuerprogramm in die Datenbank, was dann vom Thermostat abgeholt wird.\n\nDas Backend stellt klar definierte, dokumentierte und den gängigen Standards entsprechenden Webservice Schnittstellen bereit. Dies gewährleistet, dass die Datentransfers einheitlich sind und die Aufgaben der Bereiche KI / Data-Science, Datenhaltung, Anmeldung/Verwaltung der IoT-Devices klar getrennt sind.\n\n\u003cstrong\u003eWeitere Sensoren und Wetterdienst\u003c/strong\u003e\n\nWeitere Sensoren wie Bewegungsmelder, Außentemperatur oder Wassertemperaturfühler verbessern die Steuerung. Auch ein Fenstersensor, der das Öffnen der Fenster erkennt, wäre wertvoll, um die Steuerung entsprechend anzupassen. Zusätzlich ist die Wettervorhersage per Webservice ist als Informationsquelle denkbar. Die Sensoren bzw. Webservices registrieren sich im Backend und schreiben ihre Daten in die dafür vorgesehene Tabelle in der Datenbank. Die KI-Engine kann diese Daten mit in die Berechnungen einfließen lassen.\n\n\u003cstrong\u003eDas Nutzer-Interface\u003c/strong\u003e\n\nDie Endanwenderin soll bequem seine Wunschtemperatur programmieren können, per Webservice oder App. Dabei hat sie die Wahl zwischen einem Tages- oder einem Wochenprogramm.\n\n\u003cstrong\u003eDie KI-Engine in R\u003c/strong\u003e\n\nDie KI-Engine hat die Aufgabe, den vom Nutzer programmierten Temperaturverlauf in die richtigen Steuerungsanweisungen für das Thermostat zu übersetzen, damit der gewünschte Temperaturverlauf so genau wie möglich erreicht wird. Dabei sollen natürlich die verfügbaren Sensordaten genutzt werden. Die „Übersetzung“ ist intelligent, d.h. sie soll dazulernen und sich ständig verbessern.\n\n\u003cstrong\u003eCitizen-Science, Datenspenden, gemeinsames Testen und Entwickeln\u003c/strong\u003e\n\nIn ersten Experimenten sowohl an echten Fußbodenheizungen und an Modellen hat sich gezeigt, dass die verschiedenen Räume und Heizsysteme sehr unterschiedliche Charakteristiken haben und Störeinflüssen unterworfen sind. Um eine Lösung zu entwickeln, die nicht nur bei einer kleinen Zahl von Anwendungsfällen gut funktioniert, ist es nötig, dass eine möglichst große Zahl von Testumgebungen an Experimenten beteiligt werden. Daher wollen wir möglichst viele Enthusiasten motivieren, an dem Projekt teilzunehmen und Messdaten (anonymisiert) bereit zu stellen.","original_language":"deu","persons":["Dr. Holger Aust","Wido Wirsam"],"tags":["froscon2019","2430","Smart Home"],"view_count":303,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-06-04T09:00:04.306+02:00","length":4108,"duration":4108,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2430-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2430-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2430-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2430-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2430-die_intelligente_fussbodenheizung","url":"https://api.media.ccc.de/public/events/f4c595e4-f4df-4952-aab3-c40f38583a79","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7267,"event_guid":"d3be1b1c-4436-41e2-8257-eeed7551d999","weight":4},{"event_id":7273,"event_guid":"e26eade4-6c94-4ec4-8aab-cc265a4680cc","weight":6},{"event_id":7275,"event_guid":"74cced26-1577-4819-b09d-89dcf48312a0","weight":4},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":5},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":5},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":15},{"event_id":7293,"event_guid":"76a298ab-b778-4241-a467-9c5fbd7878f1","weight":9},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":7},{"event_id":7298,"event_guid":"f87f303a-5b65-4cfe-b4b6-54c8557e868e","weight":12},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":3},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":4},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":4},{"event_id":7334,"event_guid":"4bd45e4a-c05c-4804-b879-4b793b7fca4e","weight":4},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":6}]},{"guid":"74057cdb-d705-4603-b56c-f15383df0747","title":"Barrierefreie Webseiten - für wen eigentlich?","subtitle":null,"slug":"froscon2019-2348-barrierefreie_webseiten_-_fur_wen_eigentlich","link":"https://programm.froscon.de/2019/events/2348.html","description":"Sind barrierefreie Webseiten nur für bestimmte Nutzergruppen relevant?

befindet sich im Umbruch und erfährt nicht zuletzt durch agile Konzepte und DevOps einen enormen Bedeutungszuwachs. Der Trend scheint klar: „Everything is Code and code is law“.\nGleichzeitig wächst damit die Verantwortung in Hinblick auf das Thema Security, dabei steigt die Anzahl von Cyber-Attacken und Sicherheitsvorfällen seit Jahren kontinuierlich. Es stellt sich die Frage, wie gut die Entwickler von heute in Bezug auf die Schaffung einer zukunftsfähigen, sicheren Infrastruktur im Kontext der Digitalisierung vorbereitet sind!\n\nDoch auch die Security Branche muss sich bewegen: Althergebrachte Konzepte einer reinen Perimetersicherheit und aufwendiger, zeitraubender Penetrationstests funktionieren in einer Welt kontinuierlicher Deployments und flexibel skalierender Microservices schlicht nicht mehr. Auch fehlt es an der dringend benötigten Transparenz über die tatsächliche Verwundbarkeit der eigenen Systemlandschaft.\n \nGemeinsam wollen wir den Finger in die Wunde legen und Forderungen an Entwickler wie auch Security Verantwortliche formulieren. Dabei stehen konkrete Lösungsansätze im Vordergrund, wie sich die Herausforderung von morgen gemeinsam bewältigen lassen.\nSo viel vorweg: Statische Code Analyse alleine ist weder innovativ noch zielführend…\n","original_language":"deu","persons":["Jan Sudmeyer"],"tags":["froscon2019","2421","Security"],"view_count":293,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-06-12T16:15:05.018+02:00","length":2871,"duration":2871,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2421-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2421-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2421-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2421-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2421-everything-as-code_anything_secure","url":"https://api.media.ccc.de/public/events/f8665fe1-8ffa-4ec0-8924-17933c87ebcf","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7267,"event_guid":"d3be1b1c-4436-41e2-8257-eeed7551d999","weight":5},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":6},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":7},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":6},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":5},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":4},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":6},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":8},{"event_id":7321,"event_guid":"f1ce2f38-4601-416a-bfb9-b7e004be5006","weight":5},{"event_id":7326,"event_guid":"07c3d074-21f6-4f86-aaef-090946823dbc","weight":4},{"event_id":7335,"event_guid":"ab1cb567-0f2a-49d8-ab5d-f5a4491c1fb3","weight":4}]},{"guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","title":"Ist FreeIPA eine Alternative zur Active Directory?","subtitle":null,"slug":"froscon2019-2434-ist_freeipa_eine_alternative_zur_active_directory","link":"https://programm.froscon.de/2019/events/2434.html","description":"Vorstellung FreeIPA als Alternative / Ergänzung zur Active Directory.\n\n\nVorstellung was FreeIPA ist und aus welchen Komponenten es sich zusammen setzt.

Today web pages and web applications have to work a large variety of devices. On top of these requirements web developers have also to care about accessibility. The primary guidelines for accessible web pages are the Web Content Accessibility Guidelines published by the W3C. These guidelines define several requirements for accessible web pages. The W3C also publishes recommendations how these guidelines can be implemented. Currently a new standard is in development which specifies a format for writing rules for testing the accessibility of web pages and to harmonize the interpretation of the guidelines.\n\nNevertheless, evaluating the accessibility of a web page is a time consuming task. The process can also be error prone, depending on the experience of the user [1]. This talk will present the prototype of semiautomatic tool for evaluating the accessibility of web pages. The tool uses a combination of automatic and guided manual testing to make accessibility evaluations less time consuming and error prone. For implementing the tool several well known projects like Selenium are used. The first part of the talk will give a brief overview about the standards for accessible web pages and the procedures for testing the accessibility of web pages. One of the main challenges in the development of the tool was the modeling of the rules for accessible web pages in a machine readable way. In the main part of the talk the model used for the rules as well as the implementation of the test procedures will be discussed. The last part of the talk will be a live demonstration of the of the tool presented in this talk.","original_language":"eng","persons":["Jens Pelzetter"],"tags":["froscon2019","2490","FrOSCon meets Science"],"view_count":49,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-01-15T16:00:06.663+01:00","length":1741,"duration":1741,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2490-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2490-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2490-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2490-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2490-a_semiautomatic_approach_for_testing_the_accessibility_of_web_pages","url":"https://api.media.ccc.de/public/events/e4bf7a75-94f6-4229-ac28-a68e7cc3c3aa","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":3398,"event_guid":"22f1f4b9-d58a-4b07-b5ad-85048efb5f91","weight":1},{"event_id":5818,"event_guid":"f730ef2e-a133-4174-ae95-3d7c012b4b09","weight":1},{"event_id":7265,"event_guid":"480a501f-cb98-4af1-bbab-273c383e2080","weight":1},{"event_id":7267,"event_guid":"d3be1b1c-4436-41e2-8257-eeed7551d999","weight":2},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":1},{"event_id":7270,"event_guid":"2a276b5d-b77c-4074-a741-8651e93418f8","weight":1},{"event_id":7271,"event_guid":"f4c595e4-f4df-4952-aab3-c40f38583a79","weight":2},{"event_id":7273,"event_guid":"e26eade4-6c94-4ec4-8aab-cc265a4680cc","weight":3},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":1},{"event_id":7277,"event_guid":"9ec7cfe0-ad58-4f17-b3a1-33646bdec326","weight":3},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":3},{"event_id":7280,"event_guid":"b8a483e8-02bb-4382-8697-b023c1de1cd3","weight":4},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":2},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":3},{"event_id":7283,"event_guid":"a0f3dab2-13d6-41b4-b15d-e855f6f36d2d","weight":1},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":1},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":1},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":1},{"event_id":7288,"event_guid":"8b3077e1-5591-426c-903d-0e00dfb9836b","weight":4},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":1},{"event_id":7293,"event_guid":"76a298ab-b778-4241-a467-9c5fbd7878f1","weight":1},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":1},{"event_id":7297,"event_guid":"e3cbd7a8-c747-42e3-93c3-990adb6d6c0e","weight":1},{"event_id":7302,"event_guid":"93a15d95-8f95-42b5-abec-ffeb4f88035f","weight":1},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":1},{"event_id":7311,"event_guid":"fbac57d8-37e3-4c5e-a97f-44e9019b6ca7","weight":1},{"event_id":7312,"event_guid":"d140d6af-5f70-4dca-aea7-1019989e4f76","weight":1},{"event_id":7313,"event_guid":"7327aca1-14dd-4314-90f5-89546a1354b4","weight":1},{"event_id":7318,"event_guid":"f36a5187-0a6b-40f2-a695-2f3585f2b6f6","weight":1},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":1},{"event_id":7323,"event_guid":"7adbca81-10f6-4634-aab9-47cecfa25390","weight":1},{"event_id":7324,"event_guid":"33f1ee15-b584-4dc2-94d4-b593dfb428de","weight":1},{"event_id":7325,"event_guid":"9279d4b2-71f4-4b6a-8b65-d40cdeb75b1a","weight":1},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":3},{"event_id":7331,"event_guid":"74057cdb-d705-4603-b56c-f15383df0747","weight":3},{"event_id":7335,"event_guid":"ab1cb567-0f2a-49d8-ab5d-f5a4491c1fb3","weight":3},{"event_id":7343,"event_guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","weight":3},{"event_id":7350,"event_guid":"0b1f76b3-6738-4e64-95ed-565f9db20bf0","weight":1},{"event_id":7352,"event_guid":"cb6ed95d-a208-438f-8ea5-a16916a8a89e","weight":1},{"event_id":7354,"event_guid":"fe017cb4-5ec9-47a7-be7a-6eef09e06581","weight":1},{"event_id":7355,"event_guid":"a160f9d4-663b-4237-b56a-20d065ade180","weight":1}]},{"guid":"9186fc88-b1f8-45fc-8dcb-a375e029680d","title":"MySQL Best Practices - In 8 Schritten zur optimierten Datenbank!","subtitle":"Ein Einblick in die 'Best Practices' nach der MySQL Installation...","slug":"froscon2019-2442-mysql_best_practices_-_in_8_schritten_zur_optimierten_datenbank","link":"https://programm.froscon.de/2019/events/2442.html","description":"Die Installation von MySQL ist denkbar einfach und geht schnell von der Hand.

Deshalb gibt es seit mehreren Jahren Tools welche das Zentrale Logging unterstützen. In diesem Vortrag soll der Elastic Stack als ein solches Tool vorgestellt werden.\n\nIn der Welt der Microservices ist die Anzahl der Logs-produzierenden Prozesse sehr groß und liegt durchaus im Bereich von 100-1000 Prozessen. Eine manuelle Log-Verarbeitung ist hier so gut wie undenkbar. Doch auch monolithische Services laufen oftmals dezentral und das Analysieren der Produktions-Logs ist dann häufig auch mit viel Aufwand verbunden. Mithilfe eines zentralen Loggins lässt sich eine viel bessere Übersicht über den Gesamtzustand eines Systems gewinnen, da nicht jedes Log einzeln untersucht werden muss, sondern die Logs aggregiert und somit auch leicht automatisiert ausgewertet werden können. Der Elastic-Stack bietet die Möglichkeit, große Mengen an Logs zu speichern und zu durchsuchen. Das Ökosystem um den ELK-Stack unterstützt Entwickler, DevOps usw. dabei, die Logs schnell und einfach aufzubereiten, damit diese gut analysierbar sind. In diesem Vortrag werden die Vor- und Nachteile des zentralen Loggins dargelegt und gezeigt, wie sich der Elastic Stack in Umgebungen einbinden lässt.

It is a software reverse engineering framework with advance capabilities like a powerful decompiler. This lecture will give a short introduction into Ghidra and cover examples of both benign executables as well as malware with a focus on the Windows operating system.\n\n\nReverse engineering - more specifically software reverse engineering - is the process of deconstructing computer programs with the purpose of understanding their feature set. This especially includes software that is not available as source code but only as binary executables. These files can be analyzed by executing them, which is often referred to as \"dynamic analysis\" or by translating them into another language, like assembly, which the reverse engineer then tries to reason about. The second approach is often referred to as \"static analysis\".\n\nWhile it is - in principle - possible for a human to fully understand and statically analyze a binary by reading raw assembly, this approach does not scale well: The x86 assembly language for example - which is used in most desktop computers and servers - is made up of thousands of different instructions. Each of these instructions only performs a very small task, like adding two integers. One can imagine that a binary - even as mundane as a tool to list the current directory content - is made up of a large number of these instructions. In practice, the reverse engineering therefore heavily relies on tooling.\n\nThe Vault 7 leak by WikiLeaks in 2017 suggested that the NSA owns or develops a reverse engineering tool called \"Ghidra\". Two years later, at the RSAConference in 2019, the NSA released the tool to the public, first as ready-to use software, then even all its source code. For the reverse engineering community, this is a huge thing: All tools available until that point in time where either very expensive or lack advanced capabilities.\n\nWhile this lecture will only cover executables for the Microsoft Windows operating system, Ghidra also supports a very wide variety of platforms reaching from ARM - used in many IoT devices - over DEX - for Android-based devices to more exotic architectures as PowerPC, MIPS or SPARC. This versatility is a huge pro for Ghidra when compared to its main competing software product like the Hex-Rays decompiler.\n\nA lot of people think, that reverse engineering is a dark art only a few selected individuals are chosen to be gifted in. I honestly think that it is just another skill and would even go as far as saying that maintaining a legacy software product without good documentation - which is a common scenario in the software development industry - is much harder than understanding how WannaCry worked.","original_language":"eng","persons":["larsborn"],"tags":["froscon2019","2350","Security"],"view_count":657,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-07-01T14:45:06.251+02:00","length":3610,"duration":3610,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2350-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2350-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2350-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2350-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2350-ghidra_-_an_open_source_reverse_engineering_tool","url":"https://api.media.ccc.de/public/events/88474e85-c77c-466e-9351-d306b620f495","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":13},{"event_id":7273,"event_guid":"e26eade4-6c94-4ec4-8aab-cc265a4680cc","weight":9},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":13},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":9},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":11},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":11},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":9},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":20},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":11},{"event_id":7317,"event_guid":"353bc7bc-3033-4350-88ff-f753f72e683e","weight":2},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":25},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":12},{"event_id":7345,"event_guid":"a04f9f57-2046-4b50-b6da-4154bc0aa375","weight":8},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":13},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":10}]},{"guid":"403c633e-a16a-43d1-bce3-a16803851408","title":"Redis ist 10!","subtitle":"Vergangenheit, Gegenwart und Zukunft","slug":"froscon2019-2338-redis_ist_10","link":"https://programm.froscon.de/2019/events/2338.html","description":"Was als einfacher Key-Value Store mit dem ersten Code-Commit 2009 anfing, hat sich zu einer der führenden NoSQL / In-Memory Datenbanken entwickelt, die mittlerweile selbst ein wichtiger Bestandteil von vielen Open Source Projekten ist. Da alle Daten \nim Hauptspeicher gehalten werden, ist die Schnelligkeit bzw. minimale Latenz bei der Verarbeitung einer der primären Vorteile dieser Datenbank. Ob als schneller Cache, der beim Zugriff auf eine herkömmliche Datenbank die Zugriffszeiten gering hält oder\nals vollständige Datenbank, die Millionen von Transaktionen pro Sekunde stemmt, Redis ist für mehr und mehr Entwickler der Datenspeicher der Wahl, wenn es um Echtzeitanforderungen geht. 157 Klientenanbindungen in mehr als 58 Programmiersprachen sorgen für die einfache Integration in vorhandenen Quellcode oder neue Projekte.\n\nDer Vortrag gibt einen Überblick über die aktuelle Entwicklung und Richtung dieses Open Source Projektes. An eine kurze Einführung schließt sich die Darstellung der Programmierung mit Redis am Beispiel von Python an, der Programmiersprache der Wahl für Big Data und Real-Time Analytics Anwendungen. Nach einer Übersicht über die zur Verfügung stehenden Datentypen und deren Verwendung stellt die Beschreibung des Modulkonzeptes die Erweiterung von Redis als multi-modale Datenbank dar, die \nin der Lage ist, die Lücke zwischen den vorhandenen Datentypen und Applikations-spezifischen Anforderungen wie Graphen, Dokumentenspeicherung, Volltext-Suche, künstliche Intelligenz und andere mehr mit der gewohnten Performanz zu schließen.\n\nDer Vortrag schließt mit einer Betrachtung der Roadmap im Hinblick auf Redis Edge (einer speziell für den IoT-Bereich konzipierten Version), RedisGears (die Möglichkeit, mehrere Module und andere Applikations-Logik mittels Python auf der Server-Seite zur verknüpfen) sowie zukünftige Features wie verbesserter Sicherheit via einem RBAC-basierten Rollenkonzept, etc. ab.\n\nDer Fokus der Vortrags liegt hierbei weniger auf der Theorie sondern vielmehr auf der Vermittlung von praktischem Wissen. Deswegen ist z. B. geplant, Code von bereits vorhandenen Open Source Projekten zu benutzen, um die Anwendung und den Einsatz von Redis zu illustrieren.","original_language":"deu","persons":["Dr. Christoph Zimmermann"],"tags":["froscon2019","2338","Databases"],"view_count":147,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-03-13T19:00:06.076+01:00","length":3337,"duration":3337,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2338-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2338-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2338-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2338-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2338-redis_ist_10","url":"https://api.media.ccc.de/public/events/403c633e-a16a-43d1-bce3-a16803851408","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":1},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":5},{"event_id":7275,"event_guid":"74cced26-1577-4819-b09d-89dcf48312a0","weight":1},{"event_id":7277,"event_guid":"9ec7cfe0-ad58-4f17-b3a1-33646bdec326","weight":1},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":1},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":5},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":1},{"event_id":7285,"event_guid":"71c15227-527d-40e4-96c0-e04e2b218422","weight":1},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":1},{"event_id":7288,"event_guid":"8b3077e1-5591-426c-903d-0e00dfb9836b","weight":3},{"event_id":7289,"event_guid":"4e843dac-13e7-4a25-a14c-f7c89e0ddd4b","weight":1},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":4},{"event_id":7297,"event_guid":"e3cbd7a8-c747-42e3-93c3-990adb6d6c0e","weight":1},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":1},{"event_id":7303,"event_guid":"191a1aa8-7010-43a1-9f18-4099c3741307","weight":3},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":4},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":3},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":4},{"event_id":7312,"event_guid":"d140d6af-5f70-4dca-aea7-1019989e4f76","weight":1},{"event_id":7316,"event_guid":"ee11da53-1c4a-4db7-a2d4-319a66d34966","weight":1},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":2},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":4},{"event_id":7323,"event_guid":"7adbca81-10f6-4634-aab9-47cecfa25390","weight":2},{"event_id":7324,"event_guid":"33f1ee15-b584-4dc2-94d4-b593dfb428de","weight":4},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":1},{"event_id":7328,"event_guid":"dadcbdee-c37b-4faf-ba6f-56d34bc9dee7","weight":1},{"event_id":7329,"event_guid":"9186fc88-b1f8-45fc-8dcb-a375e029680d","weight":3},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":1},{"event_id":7343,"event_guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","weight":5},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":2},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":2}]},{"guid":"14529ff7-9b02-46a7-bd68-9f32b5588860","title":"Serverless ohne Vendor-Lock-In mit Go","subtitle":null,"slug":"froscon2019-2327-serverless_ohne_vendor-lock-in_mit_go","link":"https://programm.froscon.de/2019/events/2327.html","description":"Eine Codebasis für mehrere Cloud-Provider - kein Problem mit Go!\n\nServerless ist ja schön und gut, aber für jeden Anbieter muss man anders entwickeln.

Where to find insights on typical Enterprise Architecture Management concerns\n like lifecycle, security, health and so on? \nUsually these questions arise sooner or later in most projects, even smaller ones. To answer them, however, is not always easy. \n\u003cbr /\u003e\nEAM tools will help, but are not \nalways available because of costs or high ramp-up effort like learning a sophisticated meta-model or TOGAF. In addition,  architects usually design the landscape, gather information \nand have teams implement it, which results in a gap between design and current state.\n\u003cbr /\u003e\nAt times there is no dedicated architect, nor up-to-date documentation. Or generic tools are used, such as graph designers producing nice visualizations\n which are outdated at the time they are published and require much maintenance.

Technologie-Stack wie Linux, Docker, Kubernetes, OpenJDK, Spring Framework und Apache Tomcat sowie GitLab werden bei uns im Unternehmen ohne Bedenken eingesetzt. Große Unternehmen wie Google, IBM / Red Hat, Pivotal, Microsoft bauen neue Tech-Produkte und bieten sie als Open-Source an. Geschäftsmodelle mit Open-Source-Produkten funktionieren. Als jüngster Beweis kann der Kauf von Red Hat durch IBM und die Open-Source-Richtung von Microsoft durch die Integration von Linux und die Open-Source-Veröffentlichung von TypeScript und VSCode sowie der Kauf von GitHub.\n\nSoweit so gut. Etwas zu konsumieren ist immer einfacher als zu produzieren. Die Frage lautet nun: Lohnt es sich für mich als Entwickler, sich in einem Open-Source-Projekt zu beteiligen? Etwas an die Open-Source-Community zurückzugeben? Welche Vorteile und Nachteile haben Kleinunternehmen, wenn sie selbst Open-Source-Projekte gestalten bzw. wenn sie ihre Produkte als Open-Source zur Verfügung stellen?

The way in which these fields work and rely on randomness, has inspired artists and coders to explore what it means for a piece of content to be unique and be posessed by someone. We believe the best way to illustrate such problems is by actually showing how one goes from an initial random number to an actual image and this is exactly what we will doing in the talk!\n\nThe talk will start with an overall presentation of Generative Art and describe the recent influence that Machine Learning and Blockchain have had on this art form. Ample examples and references will, of course, be present. What emerged from these recent influences is a new and different way of thinking about digital content, where ownership is expressed through smart contracts on the blockchain or by secret knowledge of the initial seed used to generate the image. Throw in Open Source in the mix and it might just be impossible to make any more sense of intelectual property. As the presented material can be hard to grasp without an actual example, in the second part we will illustrate a typical workflow with which generative art is created. In the process, the audience will have the opportunity to explore different generation and structuring techniques, fundamental building blocks of the art form, like pseudorandom number generator, seeds, simple probability distributions, and the issues one often has to deal with.","original_language":"eng","persons":["Mihail Luchian"],"tags":["froscon2019","2376","Culture"],"view_count":52,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-05-09T22:00:05.380+02:00","length":2735,"duration":2735,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2376-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2376-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2376-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2376-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2376-generating_uniqueness","url":"https://api.media.ccc.de/public/events/0b02e68a-5567-4083-83c9-70923ef43dc4","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7275,"event_guid":"74cced26-1577-4819-b09d-89dcf48312a0","weight":1},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":3},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":2},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":1},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":3},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":2},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":2},{"event_id":7328,"event_guid":"dadcbdee-c37b-4faf-ba6f-56d34bc9dee7","weight":3},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":4},{"event_id":7345,"event_guid":"a04f9f57-2046-4b50-b6da-4154bc0aa375","weight":2},{"event_id":7346,"event_guid":"ca6cfc09-dc85-4685-8764-af0c293c8558","weight":2},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":3},{"event_id":7351,"event_guid":"ca5e5930-ca47-41c9-b85d-73475fb75edb","weight":4},{"event_id":7352,"event_guid":"cb6ed95d-a208-438f-8ea5-a16916a8a89e","weight":2},{"event_id":7353,"event_guid":"84aca65d-603a-4fc1-844e-061cdeb14f71","weight":3},{"event_id":7354,"event_guid":"fe017cb4-5ec9-47a7-be7a-6eef09e06581","weight":3}]},{"guid":"ca6cfc09-dc85-4685-8764-af0c293c8558","title":"Sociocracy 3.0 - Natürliche Hierachien im digitalen Zeitalter","subtitle":"Kulturwandel","slug":"froscon2019-2422-sociocracy_3_0_-_naturliche_hierachien_im_digitalen_zeitalter","link":"https://programm.froscon.de/2019/events/2422.html","description":"Mit der Veröffentlichung von Frederic Laloux zu Reinventing Organizations wurde das Bild einer erstrebenswerten Organisation in Firmen der Zukunft dargestellt.\nDer Kulturwandel in Unternehmen des digitalen Zeitalters bedingt eine Veränderung der Organisationsform in Unternehmen. \n\nDer Kulturwandel in Unternehmen des digitalen Zeitalters bedingt eine Veränderung der Organisationsform in Unternehmen.

While XMPP - from a technical perspective - had some catching up to do in the last couple of years it is now ready to handle the vast majority of tasks a modern instant messaging solution is supposed to handle. (The process on how we got there has been documented in previous FrOSCon talks.) However an instant messaging system is only as good as it's implementations. This talk will look at the state of various open source implementations and at the broader XMPP community as a whole.\n\nA common theme of previous talks on XMPP has always been \"We had this interesting technical problem, found a solution to it and implemented it into one client\". (Un)fortunately the XMPP ecosystem is made of more than just one client. While catching up with modern extensions and features is slow in a system that is almost exclusively developed by volunteers, it is still happening.\nThis talk will give an overview of what various XMPP projects have been doing (implementation wise) over the last ~12 month and will try to explain why some features have been adopted more quickly than others.\nIt will also show the various ways the XMPP community has been trying to lower the barrier of entry for new developers and bringing the community closer together by organizing regular Sprints (Hackathons) and local Meetups.\nThe talk will also look into recent efforts of the community to unify the user experience across multiple clients.","original_language":"eng","persons":["Daniel Gultsch"],"tags":["froscon2019","2448"],"view_count":966,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-03-31T13:30:03.756+02:00","length":2680,"duration":2680,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2448-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2448-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2448-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2448-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2448-the_state_of_the_xmpp_community","url":"https://api.media.ccc.de/public/events/725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":35},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":20},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":24},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":35},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":19},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":18},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":17},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":17},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":46},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":31},{"event_id":7298,"event_guid":"f87f303a-5b65-4cfe-b4b6-54c8557e868e","weight":11},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":11},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":13},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":45},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":32},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":13}]},{"guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","title":"Automatisierte Linux-Wartungsarbeiten mit katprep","subtitle":null,"slug":"froscon2019-2358-automatisierte_linux-wartungsarbeiten_mit_katprep","link":"https://programm.froscon.de/2019/events/2358.html","description":"katprep ist ein Python-Toolkit zur automatisierten Wartung von über Foreman/Katello bereitgestellten Linux-Systemen. Dabei werden alle Teilschritte von der Vorbereitung (Snapshots erstellen, Monitoring ausplanen) über die Durchführung (Patche installieren) bis zur Dokumentation automatisiert. Durch den Einsatz verschiedener APIs werden gängige Hypervisor und Monitoringlösungen unterstützt.\n\n\"Single pane of glass\" und \"global dashboards\" hin oder her - Wartungsarbeiten sind komplex. In den seltensten Fällen lassen sich alle zu wartenden Systeme über einen Kamm scheren und gleichzeitig patchen. Die Realität häufig so aus: m:n-Beziehungen zwischen Betriebsystem, Hypervisor und Monitoring-Lösung. Auch wenn das eigentliche Patchen von Systemen leicht vonstatten geht, ist das administrative Vor- und Nachgeplänkel nicht immer unerheblich. Insbesondere entsprechend zertifizierte Unternehmen (z.B. ISO 27001) sind zu genauen Dokumentationen angehalten.\nNachdem ich viel Zeit und Geduld mit dem Bedienen diverser Flash-basierter Management-Frontends und Word-Vorlagen verschwendet habe, entschied ich mich für die Entwicklung eines Toolkits, welches die einzelnen Teilschritte der Systemwartung automatisiert: katprep. Unabhängig von der Anzahl der Systeme steuert dieses die folgenden Schritte:\n- Erstellen, Zurücksetzen und Entfernen von VM-Snapshots\n- Ausplanen des Monitorings\n- Software-Pakete installieren und Systeme bei Bedarf neustarten\n- Patch-Reports erstellen\nSomit lassen sich Wartungsarbeiten über eine Schnittstelle zentralisieren, keine zahlreichen Fenster und kein versehentliches Verklicken mehr!\n\nDer Vortrag behandelt die Grundlagen des Toolskits inklusive Inbetriebnahme und eine Demonstration.","original_language":"deu","persons":["Christian Stankowic"],"tags":["froscon2019","2358","System Administration"],"view_count":221,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-01-02T23:45:12.264+01:00","length":2066,"duration":2066,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2358-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2358-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2358-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2358-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2358-automatisierte_linux-wartungsarbeiten_mit_katprep","url":"https://api.media.ccc.de/public/events/6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7265,"event_guid":"480a501f-cb98-4af1-bbab-273c383e2080","weight":4},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":3},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":10},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":13},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":14},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":11},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":10},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":11},{"event_id":7297,"event_guid":"e3cbd7a8-c747-42e3-93c3-990adb6d6c0e","weight":10},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":3},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":11},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":11},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":13},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":17},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":19}]},{"guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","title":"Just Another IPv6 Talk","subtitle":null,"slug":"froscon2019-2423-just_another_ipv6_talk","link":"https://programm.froscon.de/2019/events/2423.html","description":"Linux auf dem Desktop lässt noch auf sich warten. Nutzen wir die Zeit um IPv6 zu verstehen.\n\nDer ultimative Crashkurs im IPv6 Neuland.\n\nIPv6 ist das „neue“ Internetprotokoll, welches bereits über 20 Jahre alt ist und hinreichend in der Literatur sowie in etlichen Vorträgen behandelt wurde und bei vielen (großen) Providern wie   selbstverständlich an die Kunden verteilt wird.\n\nDa müsste doch bereits alles gesagt sein. Dachte ich auch. Dennoch erlebe ich im Alltag immer wieder das Gegenteil.\n\n„IPv6? Das muss man doch ausschalten damit das Internet problemlos funktioniert.“\n\nNein, man muss sich damit beschäftigen, denn IPv6 ist das Internet.\n\nIch möchte Aufklärungsarbeit leisten und zeigen, warum man IPv6 haben möchte. Und nein, wir werden keine Standards verlesen oder RFC auswendig lernen. Es geht um die Praxis, nachlesen kann jeder Zuhause.\n\nEin paar Fragestellungen, auf die ich eingehen werde:\n    • Woher bekomme ich IPv6?\n    • Was ist dieses Dualstack und brauche ich das?\n    • Wie ist eine IPv6 Adresse aufgebaut? Was sind Prefix und Suffix?\n    • Und muss die so lang sein? Das kann sich ja keiner merken.\n    • Wie kommt die Adresse zu meinem Client (SLAAC)?\n    • Warum habe ich so viele IPv6 Adressen und gehört das so?\n    • Was ist eigentlich mit NAT?\n    • Und mit ARP, Broadcast und Multicast?\n    • Wie sieht es mit der Sicherheit und dem Datenschutz aus?\n    • Warum möchte man kein DHCPv6?\n    • Und an welcher Stelle benötigt man es doch (DHCPv6 PD)?\n    • Und weitergedacht: Geht es auch ohne Legacy IP (v4)?","original_language":"deu","persons":["Nico Isenbeck"],"tags":["froscon2019","2423","Network and Automation Track"],"view_count":1950,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-05-22T21:15:04.324+02:00","length":3611,"duration":3611,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2423-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2423-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2423-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2423-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2423-just_another_ipv6_talk","url":"https://api.media.ccc.de/public/events/7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7265,"event_guid":"480a501f-cb98-4af1-bbab-273c383e2080","weight":7},{"event_id":7275,"event_guid":"74cced26-1577-4819-b09d-89dcf48312a0","weight":34},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":7},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":32},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":31},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":36},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":37},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":20},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":34},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":35},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":36},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":35},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":54},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":73},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":24}]},{"guid":"33f1ee15-b584-4dc2-94d4-b593dfb428de","title":"Wie PostgreSQL Eure Daten Sicher Hält","subtitle":null,"slug":"froscon2019-2432-wie_postgresql_eure_daten_sicher_halt","link":"https://programm.froscon.de/2019/events/2432.html","description":"PostgreSQL ist für seine Datensicherheit berühmt - die Entwickler legen größten Wert darauf, dass die von ihm verwalteten Nutzerdaten nicht verloren gehen.

https://fai-project.org/FAIme.\n\nDieser Webdienst ermöglicht es personalisierte Installationsmedien zu\nerstellen, die eine vollautomatische Installation von Debian GNU/Linux\ndurchführen (Erweiterung auf Ubuntu in Planung). Der Dienst erstellt\nauch fertige Disk Images, mit der eine virtuelle Machine\ngestartet werden kann, oder die in einer Cloud Umgebung genutzt werden\nkönnen. Die beiden Varianten des Webdienstes nutzen das Framework FAI\n(Fully Automatic Installation) ohne das der Benutzer sich selber mit\nder FAI Konfiguration beschäftigen muss.\n\nDer Benutzer kann auf der Webseite ein Debian Release und einen\nDesktop auswählen, Passwörter setzen und eigene Softwarepakete\nhinzufügen. Aus diesen Informationen erstellt der FAI Buildserver ein\nindividuelles Installationsimage zum Herunterladen. Wird dieses Image\nvia CD oder USB-Stick gebootet, so läuft der ganze\nInstallationsprozess ohne weitere manuelle Eingabe ab. Nach wenigen\nMinuten ist der Rechner dann voll einsatzfähig.\n\nBeim Erstellen von bootfähigen Disk Images kann der Nutzer zusätzlich\ndie Größe und das Format (raw, qcow2, vmdk,...)  einstellen. Als\nDownload erhält er ein Image, das direkt in KVM, VMware oder\nVirtualBox gebootet werden kann, ohne das eine Installation noch\ndurchlaufen wird.\n\nDer Expertenmodus erlaubt weitere Einstellungen und gibt eine URL für\ndie API aus.\n\nDer Vortrag demonstriert das Erstellen verschiedener\nInstallationsmedien und Cloudimages und wie diese benutzt werden. Die\nTechnik, hinter dem Buildserver und FAI wird auch vorgestellt.","original_language":"deu","persons":["Thomas Lange"],"tags":["froscon2019","2341"],"view_count":321,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-06-28T02:30:04.905+02:00","length":3476,"duration":3476,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2341-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2341-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2341-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2341-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2341-faime_ein_service_fur_individuelle_installationen","url":"https://api.media.ccc.de/public/events/7327aca1-14dd-4314-90f5-89546a1354b4","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7264,"event_guid":"6ceb890a-a419-5fc6-bc42-3ffd7fbd73f7","weight":1},{"event_id":7265,"event_guid":"480a501f-cb98-4af1-bbab-273c383e2080","weight":2},{"event_id":7267,"event_guid":"d3be1b1c-4436-41e2-8257-eeed7551d999","weight":1},{"event_id":7270,"event_guid":"2a276b5d-b77c-4074-a741-8651e93418f8","weight":2},{"event_id":7277,"event_guid":"9ec7cfe0-ad58-4f17-b3a1-33646bdec326","weight":3},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":4},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":4},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":2},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":3},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":3},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":2},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":6},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":1},{"event_id":7299,"event_guid":"a7a44ab0-fc03-40f6-bbd3-fd556c5f2d52","weight":1},{"event_id":7306,"event_guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","weight":3},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":5},{"event_id":7310,"event_guid":"9b3d2a60-4a38-4788-95db-d75b9dd5cb47","weight":2},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":5},{"event_id":7318,"event_guid":"f36a5187-0a6b-40f2-a695-2f3585f2b6f6","weight":2},{"event_id":7321,"event_guid":"f1ce2f38-4601-416a-bfb9-b7e004be5006","weight":3},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":3},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":4},{"event_id":7329,"event_guid":"9186fc88-b1f8-45fc-8dcb-a375e029680d","weight":3},{"event_id":7335,"event_guid":"ab1cb567-0f2a-49d8-ab5d-f5a4491c1fb3","weight":4},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":2},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":2},{"event_id":7349,"event_guid":"284fbe44-a49c-4895-8aed-792efcbb4647","weight":3},{"event_id":7352,"event_guid":"cb6ed95d-a208-438f-8ea5-a16916a8a89e","weight":2},{"event_id":7353,"event_guid":"84aca65d-603a-4fc1-844e-061cdeb14f71","weight":2},{"event_id":7354,"event_guid":"fe017cb4-5ec9-47a7-be7a-6eef09e06581","weight":2}]},{"guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","title":"Dinge, die man nicht mit Git tun sollte","subtitle":"Dinge, die vielleicht nicht (ganz) so optimal sind...","slug":"froscon2019-2329-dinge_die_man_nicht_mit_git_tun_sollte","link":"https://programm.froscon.de/2019/events/2329.html","description":"Ständig versuchen Leute Git richtig zu erklären.

Ursprünglich als Oberfläche für Puppet entwickelt, übernimmt Foreman mittlerweile viele Aufgaben zur Verwaltung von Servern. U.a. kann die Provisionierung und die Konfiguration von Bare Metal, virtuellen oder auch Cloud-Servern mit Foreman automatisiert werden. Salt ist ein bedeutender Vertreter der Configuration Management Tools. Neben dem Client-Server Betrieb unterstützt Salt aber auch den clientlosen Einsatz.\n\nDurch Plugins kann die Funktionalität von Foreman erweitert werden. Mithilfe des Salt Plugins für Foreman kann Salt als Configuration Management Tool und zur Ausführung von Remote Execution Befehlen genutzt werden. Dieser Vortrag demonstriert die Automatisierung von Provisionierung und Konfiguration von Hosts mittels Foreman und Saltstack in einem Rechenzentrum. Hierbei wird auf die jüngsten Neuerungen von relevanten Foreman Funktionen und dem Salt Plugin genauer eingegangen. \n\n\n","original_language":"deu","persons":["Bernhard Suttner"],"tags":["froscon2019","2402","System Administration"],"view_count":186,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2024-12-04T14:45:02.152+01:00","length":2696,"duration":2696,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2402-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2402-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2402-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2402-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2402-saltstack_meets_foreman","url":"https://api.media.ccc.de/public/events/b3ce0272-f184-416d-ada2-07441237e632","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":5},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":2},{"event_id":7285,"event_guid":"71c15227-527d-40e4-96c0-e04e2b218422","weight":6},{"event_id":7289,"event_guid":"4e843dac-13e7-4a25-a14c-f7c89e0ddd4b","weight":6},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":6},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":2},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":1},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":4},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":4},{"event_id":7316,"event_guid":"ee11da53-1c4a-4db7-a2d4-319a66d34966","weight":4},{"event_id":7318,"event_guid":"f36a5187-0a6b-40f2-a695-2f3585f2b6f6","weight":3},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":4},{"event_id":7324,"event_guid":"33f1ee15-b584-4dc2-94d4-b593dfb428de","weight":2},{"event_id":7326,"event_guid":"07c3d074-21f6-4f86-aaef-090946823dbc","weight":7},{"event_id":7329,"event_guid":"9186fc88-b1f8-45fc-8dcb-a375e029680d","weight":2},{"event_id":7349,"event_guid":"284fbe44-a49c-4895-8aed-792efcbb4647","weight":2},{"event_id":7356,"event_guid":"58140265-5cd7-4e86-b4aa-4a506a4fd400","weight":2}]},{"guid":"191a1aa8-7010-43a1-9f18-4099c3741307","title":"Ein Katalog der DLR-Forschungssoftware für gute wissenschaftliche Praxis und mehr Open-Source","subtitle":null,"slug":"froscon2019-2492-ein_katalog_der_dlr-forschungssoftware_fur_gute_wissenschaftliche_praxis_und_mehr_open-source","link":"https://programm.froscon.de/2019/events/2492.html","description":"Die Grundsätze für die ”gute wissenschaftliche Praxis” [1] gelten als in der Forschung allgemein akzeptiert: der Erkenntnisweg soll gesichert und nachvollziehbar, Ergebnisse sollen unabhängig reproduzierbar und Grundlagen, Zwischenergebnisse und Resultate sollen dokumentiert und sichtbar sein. In vielen Bereichen der Wissenschaft wird Software eingesetzt, um den Erkenntnisprozess zu unterstützen. Um den Grundsätzen zu genügen, muss der Einsatz dieser Software ebenfalls sichtbar und nachvollziehbar sein. Am Deutschen Zentrum für Luft- und Raumfahrt e.V. (DLR) steht den wissenschaftlichen Mitarbeitenden bereits eine umfangreiche Infrastruktur zur Verfügung, die bei der nachvollziehbaren Entwicklung wissenschaftlicher Software unterstützt [2]. Dadurch wird auch die Zusammenarbeit von Instituten sowohl im Projektkontext als auch bei Inner- und Open-Source-Entwicklungen unterstützt. Allerdings gibt es bisher kein Verzeichnis, welches umfassend und vollständig die Sichtbarkeit und Auffindbarkeit von Forschungssoftware aus dem DLR adressiert. Daher möchte das DLR einen zentralen Softwarekatalog etablieren.\n\nEs gab bereits mehrere Ansätze, ein Verzeichnis der im DLR entwickelten Software zu erstellen. Durch die beiden Vorläufer des Softwarekatalogs konnten wesentliche Anforderungen identifiziert werden, die durch das neue Katalogsystem erfüllt werden müssen:\n• Die Registrierung einer Software im Katalog muss mit möglichst wenigen manuellen Eingaben erledigt werden können. Informationen aus verwendeten Entwicklungsplattformen sollen automatisiert ergänzt werden.\n• Die Pflege eines Softwareeintrags muss möglichst wenig Aufwand verursachen.\n• Die Softwareübersichtsseiten sollen gut über Suchmaschinen auffindbar sein.\n• Der Katalog und insbesondere die Softwareübersichtsseiten müssen über ein ansprechendes Design verfügen und sich intuitiv nutzen lassen.\n\nDer aktuelle Ansatz setzt auf Open-Source-Software, um die vorhandenen Informationen zu DLR-Software aus der bestehenden Infrastruktur zu extrahieren sowie optisch ansprechend und gut auffindbar bereitzustellen. Dadurch möchten wir die Sichtbarkeit von Forschungssoftware erhöhen und dazu beitragen, dass diese stärker als ein eigenständiges Forschungsprodukt wahrgenommen wird. Schließlich möchten wir die Mitarbeiter*innen des DLR für den Open-Source-Gedanken vermehrt begeistern, so dass Forschungssoftware des DLR häufiger unter einer Open-Source-Lizenz bereitgestellt wird. Im Vortrag stellen wir die Problematik der wissenschaftlichen Softwareentwicklung für die deutsche Forschungslandschaft und insbesondere für das DLR kurz vor. Anschließend motivieren wir die Ziele, die zur Erstellung des DLR-Softwarekatalogs geführt haben, und gehen insbesondere auf die Erkenntnisse aus den Vorläufern ein. Schließlich präsentieren wir den Stand des aktuellen Prototyps sowie die geplanten nächsten Schritte.","original_language":"deu","persons":["Michael Meinel"],"tags":["froscon2019","2492","FrOSCon meets Science"],"view_count":142,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-01-30T21:30:12.768+01:00","length":2566,"duration":2566,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2492-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2492-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2492-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2492-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2492-ein_katalog_der_dlr-forschungssoftware_fur_gute_wissenschaftliche_praxis_und_mehr_open-source","url":"https://api.media.ccc.de/public/events/191a1aa8-7010-43a1-9f18-4099c3741307","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7273,"event_guid":"e26eade4-6c94-4ec4-8aab-cc265a4680cc","weight":3},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":3},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":3},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":2},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":3},{"event_id":7302,"event_guid":"93a15d95-8f95-42b5-abec-ffeb4f88035f","weight":7},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":3},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":3},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":6},{"event_id":7320,"event_guid":"403c633e-a16a-43d1-bce3-a16803851408","weight":3},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":4},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":2},{"event_id":7331,"event_guid":"74057cdb-d705-4603-b56c-f15383df0747","weight":3},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":5},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":5},{"event_id":7347,"event_guid":"484939e0-a2a8-43c6-9a5a-4715149dfae2","weight":3}]},{"guid":"8b3077e1-5591-426c-903d-0e00dfb9836b","title":"How not to use OAuth","subtitle":"New security recommendations for OAuth","slug":"froscon2019-2334-how_not_to_use_oauth","link":"https://programm.froscon.de/2019/events/2334.html","description":"I am coauthoring the new security recommendations RFC for OAuth 2.0 in the IETF OAuth Working Group. In this talk, I will walk you through the MUSTs, MUST NOTs, and SHOULDs of the new recommendations.\n\nOAuth is the most important framework for federated authorization on the web. It also serves as the foundation for federated authentication using OpenID Connect. While RFC6749 and RFC6819 give advice on securing OAuth deployments, many subtle and not-so-subtle ways to shoot yourself in the foot remain. One reason for this situation is that OAuth today is used in much more dynamic setups than originally anticipated. Another challenge is that OAuth today is used in high-stakes environments like financial APIs and strong identity proving.\n\nTo address these challenges, the IETF OAuth working group is working towards a new Security Best Current Practice (BCP) RFC that aims to weed out insecure implementation patterns based on lessons learned in practice and from formal security analyses of OAuth and OpenID Connect. The BCP gives concrete advice to defend against attacks discovered recently (like the AS mix-up attack) and discourages the use of less-secure grant types such as the Implicit Grant.\n\nThis talk will outline the challenges faced by OAuth in dynamic and high-stakes environments and go into the details of the MUSTs, MUST NOTs, and SHOULDs in the new Security BCP.","original_language":"eng","persons":["Dr. Daniel Fett"],"tags":["froscon2019","2334","Security"],"view_count":428,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-02-20T15:30:06.078+01:00","length":3370,"duration":3370,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2334-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2334-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2334-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2334-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2334-how_not_to_use_oauth","url":"https://api.media.ccc.de/public/events/8b3077e1-5591-426c-903d-0e00dfb9836b","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":1},{"event_id":7265,"event_guid":"480a501f-cb98-4af1-bbab-273c383e2080","weight":1},{"event_id":7266,"event_guid":"f7f65d44-41c5-4875-a45e-59f1ff114245","weight":7},{"event_id":7267,"event_guid":"d3be1b1c-4436-41e2-8257-eeed7551d999","weight":1},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":1},{"event_id":7274,"event_guid":"f8665fe1-8ffa-4ec0-8924-17933c87ebcf","weight":2},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":4},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":11},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":9},{"event_id":7283,"event_guid":"a0f3dab2-13d6-41b4-b15d-e855f6f36d2d","weight":1},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":8},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":9},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":7},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":7},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":9},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":5},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":10},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":8},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":8},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":10}]},{"guid":"f36a5187-0a6b-40f2-a695-2f3585f2b6f6","title":"Managing and Monitoring Ceph with the Ceph Dashboard","subtitle":"Introduction / Overview and Demo","slug":"froscon2019-2395-managing_and_monitoring_ceph_with_the_ceph_dashboard","link":"https://programm.froscon.de/2019/events/2395.html","description":"The Ceph Dashboard is a web-based application that aims for providing a built-in and easy to use graphical user interface for performing a wide range of administrative tasks on a Ceph cluster.

The dashboard's various elements and components will also be shown in the form of a live demo.\n\n\nStarting with the \"Mimic\" release, the \u003ca href=\"https://ceph.com/\"\u003eCeph distributed storage project\u003c/a\u003e ships with a new web-based management and monitoring tool out of the box: the Ceph Dashboard gives Ceph Administrators an easy to use interface to manage and monitor various aspects of their cluster without having to use the CLI or any third-party utilities.\n\nIt is based on the original (read-only) Ceph Dashboard as well as the concepts and architecture of the standalone open source Ceph management framework \u003ca href=\"https://openattic.org/\"\u003eopenATTIC\u003c/a\u003e. The development of this new component is driven and coordinated by the openATTIC team at SUSE as well as engineers from Red Hat and other members of the Ceph community.\n\nFeatures include monitoring the cluster health status, managing OSDs, Pools, Ceph block devices (RBDs) and the Object Gateway (RGW). Detailed performance graphs for each component and service are provided by embedding Grafana Dashboards into the Ceph Manager Dashboard UI.\n\nThe web application is developed using the Angular web development framework; the backend code is implemented as a Ceph Manager Module based on Python and the CherryPy framework.","original_language":"eng","persons":["Lenz Grimmer"],"tags":["froscon2019","2395","System Administration"],"view_count":266,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-04-29T03:30:03.235+02:00","length":3310,"duration":3310,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2395-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2395-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2395-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2395-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2395-managing_and_monitoring_ceph_with_the_ceph_dashboard","url":"https://api.media.ccc.de/public/events/f36a5187-0a6b-40f2-a695-2f3585f2b6f6","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7266,"event_guid":"f7f65d44-41c5-4875-a45e-59f1ff114245","weight":1},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":1},{"event_id":7270,"event_guid":"2a276b5d-b77c-4074-a741-8651e93418f8","weight":1},{"event_id":7274,"event_guid":"f8665fe1-8ffa-4ec0-8924-17933c87ebcf","weight":1},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":1},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":3},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":2},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":1},{"event_id":7289,"event_guid":"4e843dac-13e7-4a25-a14c-f7c89e0ddd4b","weight":3},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":5},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":4},{"event_id":7300,"event_guid":"b3ce0272-f184-416d-ada2-07441237e632","weight":3},{"event_id":7306,"event_guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","weight":1},{"event_id":7310,"event_guid":"9b3d2a60-4a38-4788-95db-d75b9dd5cb47","weight":1},{"event_id":7313,"event_guid":"7327aca1-14dd-4314-90f5-89546a1354b4","weight":1},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":3},{"event_id":7315,"event_guid":"3be7f020-f202-4ae8-bdec-853e86554252","weight":1},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":3},{"event_id":7321,"event_guid":"f1ce2f38-4601-416a-bfb9-b7e004be5006","weight":3},{"event_id":7326,"event_guid":"07c3d074-21f6-4f86-aaef-090946823dbc","weight":3},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":1},{"event_id":7328,"event_guid":"dadcbdee-c37b-4faf-ba6f-56d34bc9dee7","weight":4},{"event_id":7329,"event_guid":"9186fc88-b1f8-45fc-8dcb-a375e029680d","weight":1},{"event_id":7330,"event_guid":"6ddb65ab-caca-407d-9c07-3cc656e8a102","weight":3},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":3},{"event_id":7334,"event_guid":"4bd45e4a-c05c-4804-b879-4b793b7fca4e","weight":3},{"event_id":7335,"event_guid":"ab1cb567-0f2a-49d8-ab5d-f5a4491c1fb3","weight":5},{"event_id":7343,"event_guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","weight":3},{"event_id":7344,"event_guid":"0b02e68a-5567-4083-83c9-70923ef43dc4","weight":1},{"event_id":7346,"event_guid":"ca6cfc09-dc85-4685-8764-af0c293c8558","weight":1},{"event_id":7349,"event_guid":"284fbe44-a49c-4895-8aed-792efcbb4647","weight":3},{"event_id":7351,"event_guid":"ca5e5930-ca47-41c9-b85d-73475fb75edb","weight":2},{"event_id":7352,"event_guid":"cb6ed95d-a208-438f-8ea5-a16916a8a89e","weight":3},{"event_id":7353,"event_guid":"84aca65d-603a-4fc1-844e-061cdeb14f71","weight":1},{"event_id":7354,"event_guid":"fe017cb4-5ec9-47a7-be7a-6eef09e06581","weight":1},{"event_id":7355,"event_guid":"a160f9d4-663b-4237-b56a-20d065ade180","weight":1},{"event_id":7356,"event_guid":"58140265-5cd7-4e86-b4aa-4a506a4fd400","weight":1},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":2}]},{"guid":"9ec7cfe0-ad58-4f17-b3a1-33646bdec326","title":"Snabb: fast software networking made simple","subtitle":"A high-performance software toolkit for packet networking written in a high-level language","slug":"froscon2019-2466-snabb_fast_software_networking_made_simple","link":"https://programm.froscon.de/2019/events/2466.html","description":"Snabb is a software toolkit for networking in userspace (also known as kernel-bypass mode).

This is a responsibility we all have, to contribute not just to our projects, but to the greater ecosystem in order to create a brighter future for everyone who interacts with any given piece of technology, whether they're using, developing, or designing it. We can become good citizens through conscientious contribution, offering the support which we are capable of, and asking for support when we need it. We must take an active role in order to create a better future for technology.\n\n\nIn free and open source software, we talk about how to contribute to individual projects. We also need to talk about the responsibilities that come along with being a participant in the greater FOSS ecosystem. In asking ourselves what it means to be good open source citizens, and how we can best accomplish that, we also have to look at how to help others do the same. Individuals, projects, foundations, nonprofits, educational institutions, and companies all have responsibilities to FOSS. These responsibilities may seem different, but they all have a similar shape: contribute, give back to the community, support the work of others, and build technology keeping the future and rights of users in mind.","original_language":"eng","persons":["Molly de Blanc"],"tags":["froscon2019","2512","other"],"view_count":317,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-01-27T06:15:04.537+01:00","length":3272,"duration":3272,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2512-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2512-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2512-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2512-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2512-open_source_citizenship_for_everyone","url":"https://api.media.ccc.de/public/events/7adbca81-10f6-4634-aab9-47cecfa25390","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":2},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":2},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":3},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":1},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":2},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":1},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":4},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":3},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":1},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":1},{"event_id":7320,"event_guid":"403c633e-a16a-43d1-bce3-a16803851408","weight":2},{"event_id":7321,"event_guid":"f1ce2f38-4601-416a-bfb9-b7e004be5006","weight":2},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":2},{"event_id":7325,"event_guid":"9279d4b2-71f4-4b6a-8b65-d40cdeb75b1a","weight":3},{"event_id":7328,"event_guid":"dadcbdee-c37b-4faf-ba6f-56d34bc9dee7","weight":2},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":3},{"event_id":7336,"event_guid":"0ef5f8b9-03f7-484b-9659-f754e8261910","weight":4},{"event_id":7340,"event_guid":"dd3a9e61-9795-43d5-b67a-3ad623bd9385","weight":1},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":3},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":2}]},{"guid":"2a276b5d-b77c-4074-a741-8651e93418f8","title":"Open Source Projekt bpmn.ai ","subtitle":"Prozesse mit Apache Spark und H2O lernen lassen","slug":"froscon2019-2440-open_source_projekt_bpmn_ai","link":"https://programm.froscon.de/2019/events/2440.html","description":"Process Engines mit Unterstützung von BPMN (Business Process Model and Notation), wie z.B.

Neben dem Einsatz in Privathaushalten haben diese Technologien auch das Potenzial, die klassische Gebäudeautomation in öffentlichen und gewerblichen Gebäuden zu ergänzen. Genau wie in einem Smart Home ermöglichen die vorwiegend drahtlosen Sensoren und Aktoren die Nachrüstung bestehender (gemieteter) Gebäude ohne die Notwendigkeit, Kabel zu verlegen. Jedoch haben öffentliche Institutionen andere Voraussetzungen und in der Folge auch andere Anforderungen, die sich von denen eines Privathauses teilweise sehr unterscheiden.\n\nDas laufende Forschungsprojekt \"Smart Public Building\" an der Hochschule für Technik Stuttgart befasst sich mit eben diesen Anforderungen öffentlicher Institutionen an den Einsatz von Smart-Home-Technologien und untersucht dabei die Möglichkeiten, öffentliche Gebäude auf Basis von Open-Source-Software zu vernetzen. Hierfür werden verschiedene Anwendungen konzipiert und prototypisch auf dem Campus der Hochschule implementiert. Zum Einsatz kommt dabei unter anderem eine Open-Source-Plattform für die Heimautomation (openHAB), die Geräte und Dienste unabhängig von Anbietern und Technologie integriert.\n\nDer Vortrag wird einige der bisher implementierten Prototypen vorstellen und diskutieren. Dazu gehört beispielsweise die zentrale Verwaltung von verteilten openHAB-Instanzen über mehrere Gebäude mittels Docker und Docker Swarm, oder auch das Smart Metering, das LoRaWAN (The Things Network) zur Kommunikation aus entlegenen Gebäudeteilen nutzt und Node-RED einsetzt, um den Datenfluss von The Things Network zu openHAB zu managen. \n\nNeben dem Einsatz von Open-Source-Software ist es auch ein Anliegen des Projektes, die Ergebnisse (Code, Dokumentation der Prototypen, Workshop-Materialien ...) wieder als Open Source zu veröffentlichen, um ihren Einsatz und die Weiterentwicklung durch andere Forschungsgruppen, öffentliche Institutionen oder am Thema Interessierte zu ermöglichen.","original_language":"deu","persons":["Myriam Guedey"],"tags":["froscon2019","2493","FrOSCon meets Science"],"view_count":140,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-06-17T09:15:03.735+02:00","length":2952,"duration":2952,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2493-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2493-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2493-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2493-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2493-smart_home_goes_public_-_open-source-software_fur_den_einsatz_in_einem_smart_public_building","url":"https://api.media.ccc.de/public/events/76a298ab-b778-4241-a467-9c5fbd7878f1","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7270,"event_guid":"2a276b5d-b77c-4074-a741-8651e93418f8","weight":3},{"event_id":7271,"event_guid":"f4c595e4-f4df-4952-aab3-c40f38583a79","weight":9},{"event_id":7273,"event_guid":"e26eade4-6c94-4ec4-8aab-cc265a4680cc","weight":6},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":1},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":1},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":11},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":4},{"event_id":7298,"event_guid":"f87f303a-5b65-4cfe-b4b6-54c8557e868e","weight":8},{"event_id":7321,"event_guid":"f1ce2f38-4601-416a-bfb9-b7e004be5006","weight":4},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":5},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":4},{"event_id":7328,"event_guid":"dadcbdee-c37b-4faf-ba6f-56d34bc9dee7","weight":3},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":4},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":4},{"event_id":7351,"event_guid":"ca5e5930-ca47-41c9-b85d-73475fb75edb","weight":4}]},{"guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","title":"Privacy by design","subtitle":"how to code GDPR and e-privacy regulation safe","slug":"froscon2019-2353-privacy_by_design","link":"https://programm.froscon.de/2019/events/2353.html","description":"The EU wants privacy by design and privacy by default.

Orchestrierung von Docker-Containern etabliert und den Kampf gegen Swarm gewonnen. Der große Vorteil von Kubernetes als Container Orchestrierungswerkzeug ist die Verbesserung der Verfügbarkeit und Stabilität von verteilten Anwendungen durch die dynamische Verteilung der Container. \n\nBeginnen werden wir beim Einstieg in die Container Welt mit der Erläuterung verschiedener Grundbegriffe. Docker ist ein Containerbasiertes System, welches weitere Ebenen der Abstraktion im Vergleich zu virtuellen Maschinen zur Verfügung stellt. In Containern läuft jedoch nicht mehr die komplette OS Umgebung, sondern nur die für die Ausführung von Applikationen benötigten Daten. Container bestehten aus einer Reihe von Layern. Wie diese zustande kommen ist Teil eines Dockerfile, welches wir besprechen werden.\n\nBasierend hierauf steigen wir in die Kubernetes Welt ein. Kubernets hat sich als Standard für die Orchestrierung von Docker-Containern etabliert. Zuerst werden wir dort die häufig verwendeten Objekte kennen lernen und wie diese zusammenarbeiten:\n1. Pods\n2. Deployments\n3. Services\n4. Secrets/Configmaps\n5. PVC/PV\n\nDie für den Betrieb eines Kubernetes Clusters benötigten Komponenten und deren Verteilung werden anschließend vorgestellt. Als einen besonderen Punkt wenden wir uns dem Thema HA im Cluster zu und versuchen Single Points of Failures im Cluster zu vermeiden. Sicherheitsaspekte spielen Im Bereich Enterprise eine wichtige Rolle. Hierzu werden wir uns RBAC, Namespaces und Isolated Pods anschauen.\n\nNach dem theoretischen Teil analysieren wir, wie wir eine Anwendung in unser Cluster deployen können und diesen Deploymentprozess nachverfolgen und debuggen können. Hierbei werden wir sowohl die Kubernetes CLI als auch das Kubernetes Dashboard kennen lernen. Als Start werden wir das Tool Minikube nutzen, welches auf einem lokalen Rechner ein Single-Node Kubernetes deployed, was für die Entwicklung von Anwendungen ein optimales Spielfeld bietet.\nWeitere Themen werden der Package Manager Helm, die Container-Plattform OpenShift und Deployment Pipelines bilden, welche wir schon im praktischen Einsatz haben. \nAls kleines Schmankerl bietet sich im letzten Teil des Talks an über das Thema Monitoring von Kubernetes zu referrieren. \n\nDer Talk wird sich maßgeblich auf das Verständnis der Architektur und deren Komponenten fokussieren. Es werden Möglichkeiten und Tools aufgezeigt welche das Setup eines Kubernetes Clusters maßgeblich vereinfach können, ohne im Detail diese während des Workshops auszuführen.","original_language":"deu","persons":["Oleg Fiksel","Michael Siebertz","Sean"],"tags":["froscon2019","2331","System

In this paper we summarize our experiences which we gathered during several semesters of conducting electronic exams in combination to electronically assisted grading and our research to further automate this process.\n\nSince 2012 in the department of computer science in Hochschule Bonn-Rhein-Sieg electronic exams using various digital format were carried out. In 2018, the first grading-assisted digital exam for the bachelor course ”Grundlagen der Wahrscheinlichkeitstheorie und Statistik” (WuS) with 120 students was conducted. Based on the literature study and practical experiences, we identify requirements for conducting an electronic exam and how we selected the respective implementation of a suitable format, for which we used Jupyter notebook 2 . We introduce its advantages and limitations as well as discuss the types of assignments which can be utilized in Jupyter notebooks. Despite multiple benefits from the plain use of a digital format in examinations, the major reduction of the teacher’s workload is reached by using grading assistance. We have studied various auto grading techniques which assist an examiner during the grading process, applied some of them for WuS assignments and show the significant time reduction achieved for grading students’ exam using only partial auto grading.","original_language":"eng","persons":["Tim Metzler","Deebul Nair"],"tags":["froscon2019","2491","2019","FrOSCon meets Science"],"view_count":46,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-09-09T02:00:00.000+02:00","updated_at":"2024-08-05T00:30:02.257+02:00","length":2307,"duration":2307,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2491-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2491-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2491-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2491-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2491-towards_digitalisation_in_examination_and_grading_best_practice_and_challenges","url":"https://api.media.ccc.de/public/events/b47ce385-2fe7-48f6-bc0a-92b0f1f08519","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":2269,"event_guid":"C4w30id6HpMnzKM2xcrT4g","weight":1},{"event_id":5914,"event_guid":"bd7d06d7-8889-51fa-854e-021d23b79183","weight":1},{"event_id":6408,"event_guid":"ffdc92f3-1a39-4931-9409-f8bfabe9f628","weight":1},{"event_id":6435,"event_guid":"9777cea0-ac06-4274-85db-908c1e87e2f4","weight":1},{"event_id":6457,"event_guid":"74b9c748-970f-4693-ac7e-46fcc733d2b4","weight":1},{"event_id":6488,"event_guid":"8943659a-536d-4afb-85de-f1b8b29a7902","weight":1},{"event_id":6551,"event_guid":"3a571c21-31ed-453b-886d-7dea7b5751cd","weight":1},{"event_id":6577,"event_guid":"49fe1044-4038-4cec-8e80-71621c9e7d6e","weight":1},{"event_id":6741,"event_guid":"d1a8fbc3-8ee3-5ffd-bfa6-b7ec845b6859","weight":2},{"event_id":7151,"event_guid":"822892f3-a720-5a46-b933-2eb5524f6f28","weight":1},{"event_id":7223,"event_guid":"1a1de145-1e96-4705-9c4c-cfbd896af3d5","weight":1},{"event_id":7249,"event_guid":"515128bb-19ca-46cb-aeb3-2ba50a68d6b2","weight":1},{"event_id":7250,"event_guid":"a97c8df9-30a7-59e5-bbe4-dbe18cd13572","weight":1},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":2},{"event_id":7368,"event_guid":"e1b56229-fb1e-480c-9691-c137ec11ee51","weight":1},{"event_id":7371,"event_guid":"074a5ea0-fd00-4529-912c-c986a8856f6b","weight":1},{"event_id":7389,"event_guid":"ed4b6c75-14f4-49fe-a11e-3762bd6b54e3","weight":1},{"event_id":7485,"event_guid":"ff3d02e2-9cb3-5bd6-b029-e9a5dd32d985","weight":1},{"event_id":7782,"event_guid":"448feb01-9247-5f6f-8be4-e61a78249549","weight":1},{"event_id":7785,"event_guid":"d029ea6e-7755-5c91-bb0b-764e51e7a34a","weight":2},{"event_id":7788,"event_guid":"6986d495-b3e9-5388-851b-cb4d4f0a79ff","weight":2},{"event_id":7790,"event_guid":"c5af3e23-62d2-56fa-bc43-f2645f225e7d","weight":1},{"event_id":7791,"event_guid":"3418e4c7-2415-5c0e-b6c7-b7dea044bf1e","weight":1},{"event_id":7794,"event_guid":"624c002f-4996-56ea-8130-28fbcdb53869","weight":2},{"event_id":7796,"event_guid":"14529ff7-9b02-46a7-bd68-9f32b5588860","weight":1}]},{"guid":"e3cbd7a8-c747-42e3-93c3-990adb6d6c0e","title":"AppArmor Crashkurs","subtitle":"Lerne in unter einer Stunde, AppArmor-Profile zu erstellen und zu pflegen!","slug":"froscon2019-2399-apparmor_crashkurs","link":"https://programm.froscon.de/2019/events/2399.html","description":"\u003cp\u003eAppArmor ist eine einfach zu benutzende Linux-Sicherheitssoftware, die Programmen nur das erlaubt, was sie laut ihrer Security Policy, genannt Profil, dürfen.\n\n\u003cp\u003eDer Vortrag erklärt den Einsatz von AppArmor in der Praxis.

Doch auch jenseits moderner Microservice-Architekturen finden Container-Lösungen, beispielsweise im HPC, Anklang. So hat dort außer Docker allen voran Singularity einen hohen Verbreitungsgrad erzielt, aber auch Shifter, udocker und Charliecloud buhlen um die Gunst der Administratoren und Anwender.\n\nEinleitend beleuchtet der Vortrag welche Probleme des HPCs sich mit Containern entschärfen lassen und frischt noch mal auf, welche Technologien Containern zugrunde liegen. Der Fokus des Vortrags liegt auf den unterschiedlichen Container Engines und ihren Besonderheiten, speziell wie sie im Vergleich zu im Enterprise-Umfeld anzutreffenden Varianten die Isolation realisieren.\n\nZiel des Vortrages soll hierbei nicht sein, das Für und Wider der einzelnen Lösungen im Detail auszudiskutieren, sondern einen Überblick über den Docker Tellerrand hinweg zu liefern. Zusätzlich wird beleuchtet, warum sich Orchestrierungslösungen wie Kubernetes im HPC Umfeld nach wie vor schwer tun.","original_language":"deu","persons":["Holger Gantikow"],"tags":["froscon2019","2404","System Administration"],"view_count":260,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-06-08T12:00:03.460+02:00","length":3611,"duration":3611,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2404-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2404-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2404-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2404-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2404-linux_container_im_high_performance_computing","url":"https://api.media.ccc.de/public/events/480a501f-cb98-4af1-bbab-273c383e2080","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":11},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":4},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":9},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":12},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":16},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":9},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":12},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":10},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":11},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":15}]},{"guid":"f7f65d44-41c5-4875-a45e-59f1ff114245","title":"Hexagonale Architektur in Microservices","subtitle":"Domain zentrierte Microservices","slug":"froscon2019-2411-hexagonale_architektur_in_microservices","link":"https://programm.froscon.de/2019/events/2411.html","description":"Die hexagonale Architektur ist eine Alternative zur weit verbreiteten 3-tier Architektur basierend aus Controllern, Services und Repositories. Anders als auf Schichten, wird hier das Augenmerk auf Hüllen gelegt, wobei die fachliche Domäne das Zentrum der Architektur bildet.\nDieser Vortrag zeigt zunächst die konzeptionellen Eigenschaften der hexagonalen Architektur und ihre Vor- und Nachteile. Im Anschluss wird an einem Beispiel gezeigt, wie man eine klassische 3-tier Architektur in eine hexagonale Architektur überführt und dabei fachliche Themen zentriert.\n\nWir alle kennen die typische Backendarchitektur bestehend aus Controllern, Services und Repositories. Gewachsen aus der klassischen 3-tier Architektur, wird sie auch heute noch sehr oft in Microservices eingesetzt. \nAus der technischen Trennung ergeben sich allerdings in wachsenden Komponenten zusehends Probleme. Oft werden fachliche Themen mit technischen Implikationen vermischt, da nicht klar ist, wo Fachlogik eigentlich verortet werden soll. Im Controller finden sich Datenvalidatoren, im Service Berechnungen und im Repository oder gar direkt in der Datenbank fachliche Vor- und Nachbedingungen. Fachliche Einzelteile werden dann über Komponenten hinweg orchestriert und erhält oft ein dichtes Netz an Abhängigkeiten zwischen den Schichten. Eine Antwort auf die Frage „Was tut meine Software eigentlich?“ wird dadurch immer weiter erschwert und auch die Wart- und Testbarkeit leidet stark darunter.\nEine Alternative bildet hier die hexagonale Architektur. Anders als die Top-Down Architekturen, baut sie auf eine Hüllenarchitektur auf, in deren Mitte die fachliche Domäne beheimatet ist. Nur hier werden fachliche Themen behandelt, Vor- und Nachbedingung geprüft und Daten auf Plausibilität geprüft. Als Nebeneffekt erhält man dabei eine zentrale Stelle der „Wahrheit, dieim Code liegt“.\nVon innen nach außen wird die Domäne von der Applikationsschicht und die Portschicht eingehüllt. Während sich die Applikationsschicht um die Umwandlung technischer Objekte in fachliche und der Orchestrierung zusammenhängender Domainobjekte widmet, bildet die Portschicht die Verbindung in die Außenwelt. Dabei ist unerheblich ob Daten per HTTP in das System gelangen oder per (O/J)DBC in eine Datenbank gestreamt werden.","original_language":"deu","persons":["Christian Iwanzik"],"tags":["froscon2019","2411","Development"],"view_count":421,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2024-11-13T17:30:02.579+01:00","length":2943,"duration":2943,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2411-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2411-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2411-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2411-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2411-hexagonale_architektur_in_microservices","url":"https://api.media.ccc.de/public/events/f7f65d44-41c5-4875-a45e-59f1ff114245","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":4485,"event_guid":"da208942-2be8-4f14-9466-ba8e7b74fca8","weight":1},{"event_id":7265,"event_guid":"480a501f-cb98-4af1-bbab-273c383e2080","weight":5},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":1},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":1},{"event_id":7275,"event_guid":"74cced26-1577-4819-b09d-89dcf48312a0","weight":2},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":2},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":13},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":10},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":9},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":8},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":9},{"event_id":7292,"event_guid":"b3ebf68d-8a2a-4564-ab24-e013dc92ba1c","weight":1},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":2},{"event_id":7299,"event_guid":"a7a44ab0-fc03-40f6-bbd3-fd556c5f2d52","weight":1},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":6},{"event_id":7330,"event_guid":"6ddb65ab-caca-407d-9c07-3cc656e8a102","weight":8},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":9},{"event_id":7345,"event_guid":"a04f9f57-2046-4b50-b6da-4154bc0aa375","weight":5}]},{"guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","title":"Statische Codeprüfung","subtitle":"Tools, die die Programmierung erleichtern","slug":"froscon2019-2454-statische_codeprufung","link":"https://programm.froscon.de/2019/events/2454.html","description":"Fehler in Programmen kann man selber lange suchen -

Es ist Zeit, all die Anekdoten, Ereignisse und Kuriositäten zu betrachten, die Open Source und Freie Software geprägt und auch auf die Probe gestellt haben. Michael Kleinhenz und Oliver Zendel waren von Anfang an dabei und geben einen ironisch-amüsanten Rückblick auf die Entwicklung einer Kulturtechnologie deren Auswirkungen heute weit über die Technologieszene hinaus wirksam sind.\n\n20 Jahre alt ist der Begriff \"Open Source\" geworden. Ein Grund zum Feiern - und ein Grund einmal einen Rückblick auf zwei Dekaden einer sich im Wandel befindenden Bewegung zu geben. Oliver Zendel und Michael Kleinhenz waren von Anfang an dabei und haben durch ihre Arbeit für den LinuxTag e.V. viele Begegnungen und Erlebnisse mit den Akteuren der Bewegung gehabt. Aus hunderten von Anekdoten, Geschichten, Hintergründen und direkten Beteiligungen schöpft ein ironischer Rückblick auf eine Zeit in der sich nicht nur die Bedeutung von Software und deren Bedeutung für eine offene Gesellschaft gewandelt hat, sondern auch die Art wie wir mit Technik umgehen, diese erleben und erfahren.\n\nDer Vortrag bietet eine Reise durch 20 Jahre Open Source, vom holprigen Beginn und den ersten Schritten bis zur Wandlung zur Grundlage aller moderner Technologie und der Durchdringung von Bereichen außerhalb der Software- und Technologiewelt. Dabei wird immer wieder mit einem Augenzwinkern auf Anekdoten, Ereignisse und Kuriositäten geblickt, die eine Kulturtechnologie geprägt und beeinflusst haben.","original_language":"deu","persons":["Michael Kleinhenz","Oliver Zendel"],"tags":["froscon2019","2340","New horizons"],"view_count":143,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2024-05-29T14:45:07.264+02:00","length":3667,"duration":3667,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2340-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2340-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2340-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2340-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2340-state_of_the_union_2019","url":"https://api.media.ccc.de/public/events/55e6c5cd-56b2-4c3b-ae96-880b624c2788","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":5754,"event_guid":"acca1d2a-792c-4ef0-a76a-33622dc89a7f","weight":1},{"event_id":5766,"event_guid":"73f1dcb2-25ba-48ff-a02a-3abc33360f03","weight":1},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":1},{"event_id":7273,"event_guid":"e26eade4-6c94-4ec4-8aab-cc265a4680cc","weight":1},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":9},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":7},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":10},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":6},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":7},{"event_id":7299,"event_guid":"a7a44ab0-fc03-40f6-bbd3-fd556c5f2d52","weight":3},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":5},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":6},{"event_id":7336,"event_guid":"0ef5f8b9-03f7-484b-9659-f754e8261910","weight":4},{"event_id":7343,"event_guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","weight":6},{"event_id":7353,"event_guid":"84aca65d-603a-4fc1-844e-061cdeb14f71","weight":7}]},{"guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","title":"Die DSGVO als Chance nutzen","subtitle":" Ein Fahrplan für ein mehr an Informationssicherheit in kleinen Schritten mit Open Source Software","slug":"froscon2019-2408-die_dsgvo_als_chance_nutzen","link":"https://programm.froscon.de/2019/events/2408.html","description":"Data Breaches, Datenschutzverstösse und Ransomware Angriffe erscheinen täglich in den Medien.

I create a pipeline (Jenkins or Gitlab CI/CD) to convert a simple ascii text to any documentation format. So when your project needs  html that's fine, when your customer needs some PDF and you want to use your company logo that's nearly the same. You can create multiple outputs from one source, update screenshots automatically and still edit it on any of your devices or editors. Using a pipeline and containers after commiting to a version control system can be used on any operating system, or directly in the cloud.

Dabei gehen wir auf die Herausforderungen der jeweiligen Services ein, wie \"cold start\" bei Lamda oder \"provisioned throughput\" bei DynamoDB. Dabei zeigen wir, welche Strategien und Wege es gibt, damit umzugehen. Außerdem behandeln wir solche Themen wie Tracing der Lambda-Funktionen und Implementierung von Aggregationslogik, (Scheduled) Auto Scaling und die Wahl die Capacity Mode (reserved, provisioned and on-demand) bei DynamoDB. Am Ende werfen wir einen Blick auf die erste relationale serverless Datenbank \"Aurora Serverless\" und die neue Data API.","original_language":"deu","persons":["Elmar Warken","Vadym Kazulkin"],"tags":["froscon2019","2382","Cloud"],"view_count":168,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2025-03-25T13:15:06.631+01:00","length":3433,"duration":3433,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2382-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2382-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2382-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2382-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2382-serverless_on_aws_understanding_the_hard_parts","url":"https://api.media.ccc.de/public/events/b8a483e8-02bb-4382-8697-b023c1de1cd3","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7266,"event_guid":"f7f65d44-41c5-4875-a45e-59f1ff114245","weight":4},{"event_id":7274,"event_guid":"f8665fe1-8ffa-4ec0-8924-17933c87ebcf","weight":2},{"event_id":7275,"event_guid":"74cced26-1577-4819-b09d-89dcf48312a0","weight":1},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":2},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":1},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":8},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":1},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":5},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":1},{"event_id":7288,"event_guid":"8b3077e1-5591-426c-903d-0e00dfb9836b","weight":5},{"event_id":7289,"event_guid":"4e843dac-13e7-4a25-a14c-f7c89e0ddd4b","weight":1},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":1},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":1},{"event_id":7298,"event_guid":"f87f303a-5b65-4cfe-b4b6-54c8557e868e","weight":6},{"event_id":7306,"event_guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","weight":1},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":5},{"event_id":7325,"event_guid":"9279d4b2-71f4-4b6a-8b65-d40cdeb75b1a","weight":3},{"event_id":7330,"event_guid":"6ddb65ab-caca-407d-9c07-3cc656e8a102","weight":7},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":9},{"event_id":7334,"event_guid":"4bd45e4a-c05c-4804-b879-4b793b7fca4e","weight":2}]},{"guid":"07c3d074-21f6-4f86-aaef-090946823dbc","title":"Foreman/Katello mit Ansible automatisieren","subtitle":null,"slug":"froscon2019-2418-foreman_katello_mit_ansible_automatisieren","link":"https://programm.froscon.de/2019/events/2418.html","description":"Foreman ist ein Tool zur Verwaltung von physikalischen und virtuellen Servern.

This talk takes a look at why open source is important to business and three essential elements of this path.\n\n* Strategy: How can you monetize your open source product? Is it support, an open core approach, cloud services, or a combination of the three? And which ones are the features you can even commercialize without alienating your community?\n* Struggle: \"You received a 100 million dollars in venture capital and yet you have so many open issues?!\" Once money is involved the dynamics often change. How can you manage expectations and still build on a flourishing open source community?\n* Success: How do you balance open source and commercial success? How do you align engineering and sales decisions?\n\nThis talk takes the perspective of Elastic, the company behind the open source products Elasticsearch, Kibana, Beats, and Logstash, which makes its money with support, the commercial extensions, and cloud offerings. But we are also taking a look at how others are approaching this challenge, what worked, and what failed.","original_language":"eng","persons":["Philipp Krenn"],"tags":["froscon2019","2463","Culture"],"view_count":221,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2024-11-18T13:15:03.095+01:00","length":3642,"duration":3642,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2463-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2463-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2463-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2463-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2463-open_source_as_a_business","url":"https://api.media.ccc.de/public/events/dd3a9e61-9795-43d5-b67a-3ad623bd9385","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":1338,"event_guid":"import-a19180493d3c82f29b","weight":1},{"event_id":6275,"event_guid":"e8454584-c5ab-4cc9-86ef-64f9769207e6","weight":1},{"event_id":7147,"event_guid":"5fe8bbbe-116b-5d42-ad17-90208755ce30","weight":1},{"event_id":7163,"event_guid":"bd38872d-c3ee-45d6-b3e9-a0da37e67d1a","weight":1},{"event_id":7251,"event_guid":"b69c19ce-7c89-4afd-9396-ea664f80dba7 ","weight":2},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":3},{"event_id":7274,"event_guid":"f8665fe1-8ffa-4ec0-8924-17933c87ebcf","weight":3},{"event_id":7277,"event_guid":"9ec7cfe0-ad58-4f17-b3a1-33646bdec326","weight":3},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":6},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":3},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":1},{"event_id":7284,"event_guid":"3792767b-278f-46f3-ab92-a598a997b4de","weight":1},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":1},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":1},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":1},{"event_id":7292,"event_guid":"b3ebf68d-8a2a-4564-ab24-e013dc92ba1c","weight":1},{"event_id":7294,"event_guid":"e442db46-0a05-4439-9bcf-21bca6f714a0","weight":3},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":1},{"event_id":7299,"event_guid":"a7a44ab0-fc03-40f6-bbd3-fd556c5f2d52","weight":1},{"event_id":7302,"event_guid":"93a15d95-8f95-42b5-abec-ffeb4f88035f","weight":3},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":3},{"event_id":7306,"event_guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","weight":3},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":2},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":2},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":1},{"event_id":7312,"event_guid":"d140d6af-5f70-4dca-aea7-1019989e4f76","weight":1},{"event_id":7314,"event_guid":"b6e0153d-f5d9-41a0-a25e-9c653a0c48a1","weight":3},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":1},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":3},{"event_id":7323,"event_guid":"7adbca81-10f6-4634-aab9-47cecfa25390","weight":1},{"event_id":7325,"event_guid":"9279d4b2-71f4-4b6a-8b65-d40cdeb75b1a","weight":5},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":3},{"event_id":7328,"event_guid":"dadcbdee-c37b-4faf-ba6f-56d34bc9dee7","weight":4},{"event_id":7329,"event_guid":"9186fc88-b1f8-45fc-8dcb-a375e029680d","weight":4},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":1},{"event_id":7334,"event_guid":"4bd45e4a-c05c-4804-b879-4b793b7fca4e","weight":3},{"event_id":7336,"event_guid":"0ef5f8b9-03f7-484b-9659-f754e8261910","weight":2},{"event_id":7337,"event_guid":"c45eba70-1c43-4786-a189-eb192819cbaa","weight":1},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":5},{"event_id":7343,"event_guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","weight":6},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":1},{"event_id":7349,"event_guid":"284fbe44-a49c-4895-8aed-792efcbb4647","weight":3},{"event_id":7355,"event_guid":"a160f9d4-663b-4237-b56a-20d065ade180","weight":6}]},{"guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","title":"Neues in Open-Source-SQL-Datenbanken","subtitle":null,"slug":"froscon2019-2433-neues_in_open-source-sql-datenbanken","link":"https://programm.froscon.de/2019/events/2433.html","description":"Der SQL-Dialekt der gängigen open source Datenbanken entwickelt sich aktuell schneller denn je.

Dazu werden Key-Value Paare, bestehend aus einem Metrik-Namen sowie dem dazugehörigen Wert zu dem Zeitstempel abgespeichert.\n\nBasierend auf diesen Daten lassen sich so Systeme über einen Zeitraum überwachen und Alarme generieren. Dazu existiert die Query-Language PromQL, die eigens für Prometheus entwickelt wurde.\n\nDieser Vortrag gibt einen Praxiseinstieg in Prometheus. Zunächst erfolgt eine grundsätzliche Erklärung wie Prometheus funktioniert und wie man erste Systeme zum Erfassen der Metriken hinzufügen kann. Danach folgt auch direkt ein Einstieg in das Schreiben von eigenen Queries in PromQL und die Einbindung von Graphen in Grafana. Anschließend wird auch noch erläutert, wie man Skripte schreibt, um eigene Metriken zu exportieren, die von Prometheus erfasst werden.","original_language":"deu","persons":["Sujeevan Vijayakumaran"],"tags":["froscon2019","2431","System Administration"],"view_count":542,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-03-18T15:45:07.347+01:00","length":3001,"duration":3001,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2431-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2431-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2431-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2431-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2431-praxiseinstieg_in_prometheus","url":"https://api.media.ccc.de/public/events/4bd45e4a-c05c-4804-b879-4b793b7fca4e","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7102,"event_guid":"045f855d-1bd3-5c93-b9f3-74c5347f4ce8","weight":1},{"event_id":7106,"event_guid":"e5435c9d-3e16-5419-b326-391df1522988","weight":1},{"event_id":7259,"event_guid":"942a7a7e-a7d3-11e9-a2a3-2a2ae2dbcce4","weight":1},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":12},{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":4},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":13},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":12},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":12},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":9},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":9},{"event_id":7304,"event_guid":"98317c6b-2ff9-4276-92dc-ee41db4d7585","weight":1},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":1},{"event_id":7312,"event_guid":"d140d6af-5f70-4dca-aea7-1019989e4f76","weight":4},{"event_id":7317,"event_guid":"353bc7bc-3033-4350-88ff-f753f72e683e","weight":1},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":1},{"event_id":7321,"event_guid":"f1ce2f38-4601-416a-bfb9-b7e004be5006","weight":12},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":15},{"event_id":7327,"event_guid":"c4462ba0-f3b2-45c6-aca5-5ef5da2e55db","weight":1},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":21},{"event_id":7336,"event_guid":"0ef5f8b9-03f7-484b-9659-f754e8261910","weight":2},{"event_id":7337,"event_guid":"c45eba70-1c43-4786-a189-eb192819cbaa","weight":1},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":14},{"event_id":7342,"event_guid":"88474e85-c77c-466e-9351-d306b620f495","weight":1}]},{"guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","title":"Was ist dieses smart in SmartHome?","subtitle":null,"slug":"froscon2019-2460-was_ist_dieses_smart_in_smarthome","link":"https://programm.froscon.de/2019/events/2460.html","description":"Die kurze Antwort: Du. \nDas smarte Home ist derzeit nicht mehr, als die digitalisierte Version einer Hausautomatisierung.

Dieser Vortrag gibt eine praktische Einführung in den zugrunde liegenden Ansatz und das Tool, komplett mit einer Life Coding Sitzung.","original_language":"eng","persons":["Jeremias Rößler"],"tags":["froscon2019","2449","Web Development"],"view_count":136,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-04-22T12:45:06.646+02:00","length":2607,"duration":2607,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2449-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2449-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2449-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2449-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2449-recheck_und_der_stein_der_weisen","url":"https://api.media.ccc.de/public/events/fbac57d8-37e3-4c5e-a97f-44e9019b6ca7","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":2868,"event_guid":"0549d204-604a-46c5-92a2-e64b85aa9892","weight":3},{"event_id":6115,"event_guid":"93b7d8a6-345b-405a-a3f2-0dc09ddd2e28","weight":3},{"event_id":7236,"event_guid":"e3bdda0e-c95f-4021-8500-3718a2913352","weight":3},{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":1},{"event_id":7280,"event_guid":"b8a483e8-02bb-4382-8697-b023c1de1cd3","weight":4},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":3},{"event_id":7282,"event_guid":"42a1e544-fae1-439c-95c0-d47d4fa94758","weight":3},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":2},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":4},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":1},{"event_id":7296,"event_guid":"b8424140-1639-44f7-a19a-67af58ad61e9","weight":2},{"event_id":7302,"event_guid":"93a15d95-8f95-42b5-abec-ffeb4f88035f","weight":3},{"event_id":7303,"event_guid":"191a1aa8-7010-43a1-9f18-4099c3741307","weight":1},{"event_id":7306,"event_guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","weight":3},{"event_id":7310,"event_guid":"9b3d2a60-4a38-4788-95db-d75b9dd5cb47","weight":1},{"event_id":7345,"event_guid":"a04f9f57-2046-4b50-b6da-4154bc0aa375","weight":3},{"event_id":7348,"event_guid":"d826f086-8ce2-4925-9dfa-b02db91c73ca","weight":2},{"event_id":7351,"event_guid":"ca5e5930-ca47-41c9-b85d-73475fb75edb","weight":3},{"event_id":7355,"event_guid":"a160f9d4-663b-4237-b56a-20d065ade180","weight":3}]},{"guid":"9f669988-d2f1-451f-9de1-b415a10e22b9","title":"Easy Geo-redundant Failover with MARS and systemd","subtitle":"Howto Survive Serious Disasters","slug":"froscon2019-2452-easy_geo-redundant_failover_with_mars_and_systemd","link":"https://programm.froscon.de/2019/events/2452.html","description":"The talk describes a simple setup of long-distance replication with minimum effort. The new systemd interface of MARS will drastically reduce your effort to make your existing complex solution geo-redundant.\n\nGeo-redundancy / mass data replication over long distances is now much easier to manage for sysadmins. Although systemd has some shortcomings and earns some criticism, it can ease your automation of handover / failover when combined with the new unit-file template generator from the long-distance data replication component MARS. It is very flexible, supporting arbitrary application stacks, virtual machiines, containers, and much more.\nMARS is used by 1\u00261 IONOS for geo-redundancy of thousands of LXC containers, and on several petabytes of data, with very low cost.","original_language":"eng","persons":["Thomas Schöbel-Theuer"],"tags":["froscon2019","2452","System Administration"],"view_count":90,"promoted":false,"date":"2019-08-11T00:00:00.000+02:00","release_date":"2019-08-11T02:00:00.000+02:00","updated_at":"2025-05-09T01:15:09.754+02:00","length":3673,"duration":3673,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2452-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2452-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2452-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2452-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2452-easy_geo-redundant_failover_with_mars_and_systemd","url":"https://api.media.ccc.de/public/events/9f669988-d2f1-451f-9de1-b415a10e22b9","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7268,"event_guid":"7007a0ab-a90c-4c5a-8ff2-e9faa6eba646","weight":3},{"event_id":7269,"event_guid":"313f600d-7418-4821-99fd-3d788de500ae","weight":1},{"event_id":7270,"event_guid":"2a276b5d-b77c-4074-a741-8651e93418f8","weight":1},{"event_id":7280,"event_guid":"b8a483e8-02bb-4382-8697-b023c1de1cd3","weight":1},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":2},{"event_id":7289,"event_guid":"4e843dac-13e7-4a25-a14c-f7c89e0ddd4b","weight":4},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":4},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":2},{"event_id":7313,"event_guid":"7327aca1-14dd-4314-90f5-89546a1354b4","weight":1},{"event_id":7316,"event_guid":"ee11da53-1c4a-4db7-a2d4-319a66d34966","weight":3},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":4},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":2},{"event_id":7334,"event_guid":"4bd45e4a-c05c-4804-b879-4b793b7fca4e","weight":5},{"event_id":7335,"event_guid":"ab1cb567-0f2a-49d8-ab5d-f5a4491c1fb3","weight":1},{"event_id":7339,"event_guid":"4293552f-5a33-4b91-b107-fd0246c04948","weight":4},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":5},{"event_id":7349,"event_guid":"284fbe44-a49c-4895-8aed-792efcbb4647","weight":3},{"event_id":7352,"event_guid":"cb6ed95d-a208-438f-8ea5-a16916a8a89e","weight":3},{"event_id":7353,"event_guid":"84aca65d-603a-4fc1-844e-061cdeb14f71","weight":1},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":4}]},{"guid":"a04f9f57-2046-4b50-b6da-4154bc0aa375","title":"Terraform - A more versatile tool, than you thought","subtitle":null,"slug":"froscon2019-2365-terraform_-_a_more_versatile_tool_than_you_thought","link":"https://programm.froscon.de/2019/events/2365.html","description":"Terraform is a tool, which is around for more than four years.

Test automation helps a lot, however, not all tests can be automated equally well. In settings where manual testing is the only feasible option, it is often done amateurish. This talk demos how our free web application \"SystemTestPortal\" can be used to easily test software like a pro - even in small hobby projects.\n\nTesting of software is essential. Projects that fail in this discipline deliver buggy releases and scare away their users. A lot of testing can be automated today, but many critical issues are often only detected with manual testing. However, especially small FLOSS projects often struggle hard in doing this systematically.\n\nSystematic testing sounds boring but it can be a lot of fun and bring developers, testers and end-users closer together. Thanks to the free and lightweight web application named \"SystemTestPortal\" (developed at the University of Stuttgart), creating, logging and analyzing tests can be a breeze. It also offers management functions for planning and controlling tests by offering dashboards, the ability to assign testers to test cases and so on.\n\nThe first part of this talk I will discuss the importance of testing and its challenges. In the second part, I will give a demo, showing how SystemTestPortal can help here and how it can be applied even in small hobby projects.","original_language":"eng","persons":["Daniel

to Deep Learning","subtitle":null,"slug":"froscon2019-2383-introduction_to_deep_learning","link":"https://programm.froscon.de/2019/events/2383.html","description":"Deep learning has been on a hype peak for the last 2-5 years, and it's being adopted by smaller startups and bigger enterprises alike. As an enthusiastic developer, you might be interested in getting in touch with deep learning to see what’s the hype all about, and if you’re not, you should! Deep learning could be a new way of looking at problems and developing innovative ways of solving them. By the end of this talk, you will have a good understanding of what is out there in the deep learning world, including frameworks, languages, popular existing deep learning networks, cloud providers, and more.\n\n\u003cp\u003e\nThis talk will be in three parts, first, we will present the most common deep learning frameworks, their advantages and disadvantages, and what languages they support. Then we will talk about cloud providers that support deep learning. In the last section, we will talk about our experience with deep learning on the cloud.\n\u003c/p\u003e\n\n\u003cp\u003e\nFor many frameworks, Python seems to be the preferred language, largely due to its ease of use and extensive community support. However, most frameworks also support other languages like C++, R, and Java. For the most part, a combination of preferred language and the intended use case can determine the options for a deep learning framework.\nCurrently, there are many deep learning frameworks, the most common ones are Tensorflow, Keras, Pytorch, Caffe, and Theano. Some of them excel in image classification challenges while others are more suitable for natural language processing or sentiment analysis. Your choice for the most suitable framework should depend on many factors, including the intended application, preferred language of use, and the availability of good documentation and community support. Usually, frameworks default to running on CPUs and need an extra setup to run on GPUs, but these steps are such a trivial task that it's not an important factor to consider. GPUs have a huge advantage in training and inference speed over CPUs due to their parallelization capabilities.\n\u003c/p\u003e\n\n\u003cp\u003e\nThese days there are countless cloud providers for computing power, and many of them have responded to the increase of interest in this category of AI by providing VMs specially tailored for deep learning. All the big players (Google Cloud, AWS, Azure) provide GPU enabled machines with deep learning frameworks pre-configured. However, there are smaller cloud providers who offer interesting models in order to survive the competition.\nWhen deciding on which providers to go with, one should consider many factors including pricing model, actual computing power delivered, availability regions, and the existence of pre-configured VMs for deep learning. For example, AWS has a good pricing model and great choices of deep learning frameworks, but for a while, it was impossible to provision a new machine as all of the resources were already booked. It’s also worth mentioning that some cloud providers offer trial periods or sign up credit to test their services, so always be on a look for that!\n\u003c/p\u003e\n\n\u003cp\u003e\nAt Viaboxx we are interested in trying out new technologies, so we started with deep learning by creating and running a deep learning showcase on a cloud provider. We used Keras with Tensorflow backend for the source code and Kaggle as a source of data. For a VM to perform the training we compared different cloud providers and chose a smaller one, Paperspace. Although the experience was not hiccups-free, we ended up with a good understanding of the technologies and stacks involved.\n\u003c/p\u003e","original_language":"eng","persons":["Haitham Bjanthalah"],"tags":["froscon2019","2383","Development"],"view_count":129,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2024-12-20T23:00:06.461+01:00","length":3572,"duration":3572,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2383-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2383-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2383-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2383-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2383-introduction_to_deep_learning","url":"https://api.media.ccc.de/public/events/a7a44ab0-fc03-40f6-bbd3-fd556c5f2d52","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7266,"event_guid":"f7f65d44-41c5-4875-a45e-59f1ff114245","weight":1},{"event_id":7278,"event_guid":"8f758bad-51ea-453a-9d97-6c97a614f2e4","weight":2},{"event_id":7279,"event_guid":"967fa2a1-265f-47c1-90b2-ec8dba08b328","weight":5},{"event_id":7281,"event_guid":"bb5b04bd-9599-4d93-bd12-c779f381cf5e","weight":4},{"event_id":7286,"event_guid":"a2f61e35-bf54-4cf9-9362-e4d04fa94915","weight":4},{"event_id":7290,"event_guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","weight":2},{"event_id":7292,"event_guid":"b3ebf68d-8a2a-4564-ab24-e013dc92ba1c","weight":1},{"event_id":7295,"event_guid":"1804f134-5ee8-46ff-8ea0-279350304c2a","weight":5},{"event_id":7297,"event_guid":"e3cbd7a8-c747-42e3-93c3-990adb6d6c0e","weight":4},{"event_id":7305,"event_guid":"55e6c5cd-56b2-4c3b-ae96-880b624c2788","weight":4},{"event_id":7307,"event_guid":"3f274d3f-db32-4687-95e7-ce5dcf866bee","weight":6},{"event_id":7308,"event_guid":"725bf5fc-26a0-468b-a1ee-c5e5e8154fd2","weight":4},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":4},{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":4},{"event_id":7341,"event_guid":"7100ad0c-e4f3-4784-b707-46759cd3cb6a","weight":4},{"event_id":7343,"event_guid":"212468fa-72ee-4d11-a32e-56d5e6fd78a3","weight":4}]},{"guid":"16538c49-5d11-4c6f-975e-61eb85fb1a49","title":"Proxmox VE mit Ceph \u0026 ZFS","subtitle":"Zukunftssichere Infrastruktur im Rechenzentrum","slug":"froscon2019-2438-proxmox_ve_mit_ceph_zfs","link":"https://programm.froscon.de/2019/events/2438.html","description":"Der Vortrag richtet sich an IT-Verantwortliche und Administratoren die mit Open Source-Technologien wie Proxmox VE, Ceph und ZFS eine zukunftssichere, hyperkonvergente Infrastruktur für ihr Rechenzentrum planen und implementieren wollen.

BACARDI ist Teil eines Vorhabens des Deutschen Zentrums für Luft- und Raumfahrt e.V. (DLR) zur Erfassung und Nachverfolgung von kooperativen und unkooperativen Objekten im Erdorbit. Aufbauend auf Open Source Software entsteht mit BACARDI ein System für den Einsatz im Deutschen Raumfahrkontrollzentrum, das Informationen über alle bekannten orbitalen Objekte verwaltet und aufbereitet. Im Vortrag werden wir zunächst erläutern, warum Raumfahrtrückstände überhaupt problematisch sind und welche Gefahren für aktive Objekte und Menschen im Erdorbit entstehen. Daran anschließend werden wir darlegen, warum wir in der Entwicklung Open Source Software und Bibliotheken einsetzen und weshalb wir uns für Django [3] und Apache Airflow [1] als Kernkomponenten entschieden haben.\n\nAls Schwerpunkt stellen wir die Eigenentwicklung F2x [4] vor. Diese Open Source Software dient der Anbindung von Fortran-Software an das BACARDI-\nSystem. Im Rahmen des Vortrags erläutern wir, welche Vorteile diese Software für unseren Einsatzzweck gegenüber anderen Lösungen bietet und welche Vorteile sie für andere Projekte bieten kann. Auf der BACARDI Datenbank setzen Prozesse auf, die die dort hinterlegten Orbitinformationen verarbeiten um zum Beispiel Kollisionswarnungen zu generieren. Als Betreiber von Satelliten ist das DLR direkt von Gefahren wie Kollisionen betroffen. Es forscht deshalb aktiv auf diesem Gebiet und entwickelt zur Unterstützung der Raumflugbetriebe unter anderem Modelle und Software zur Berechnung orbitaler Flugdynamik.","original_language":"deu","persons":["Martin Stoffers"],"tags":["froscon2019","2494","FrOSCon meets Science"],"view_count":99,"promoted":false,"date":"2019-08-10T00:00:00.000+02:00","release_date":"2019-08-10T02:00:00.000+02:00","updated_at":"2023-09-28T16:45:02.867+02:00","length":2090,"duration":2090,"thumb_url":"https://static.media.ccc.de/media/events/froscon/2019/2494-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/froscon/2019/2494-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/froscon/2019/2494-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/froscon/2019/2494-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/froscon2019-2494-open_source_im_bacardi_projekt","url":"https://api.media.ccc.de/public/events/93a15d95-8f95-42b5-abec-ffeb4f88035f","conference_title":"FrOSCon 2019","conference_url":"https://api.media.ccc.de/public/conferences/froscon2019","related":[{"event_id":7276,"event_guid":"9ac982ee-aeaa-431d-9622-527a14e8023c","weight":2},{"event_id":7287,"event_guid":"0ff8cbfa-b751-4107-beec-33a2678939d8","weight":1},{"event_id":7291,"event_guid":"75323cfe-eb84-4ec3-a806-16e8ca71b702","weight":1},{"event_id":7301,"event_guid":"6413e0b9-d88c-4a3c-a0a5-d4b3a0224a98","weight":4},{"event_id":7303,"event_guid":"191a1aa8-7010-43a1-9f18-4099c3741307","weight":7},{"event_id":7305,"event_guid":"55e6c5cd-56b2-4c3b-ae96-880b624c2788","weight":1},{"event_id":7306,"event_guid":"0ae9a2c9-5c51-4feb-a945-bd4f94481f14","weight":4},{"event_id":7309,"event_guid":"3e6729a3-bd01-4c16-8024-62ad8be7e3ac","weight":2},{"event_id":7310,"event_guid":"9b3d2a60-4a38-4788-95db-d75b9dd5cb47","weight":1},{"event_id":7311,"event_guid":"fbac57d8-37e3-4c5e-a97f-44e9019b6ca7","weight":1},{"event_id":7318,"event_guid":"f36a5187-0a6b-40f2-a695-2f3585f2b6f6","weight":2},{"event_id":7319,"event_guid":"d652dc05-fd17-4972-aaa3-5f678b2f7475","weight":3},{"event_id":7332,"event_guid":"50ad5991-1b2f-4a92-ba87-dec6456f085a","weight":4},{"event_id":7335,"event_guid":"ab1cb567-0f2a-49d8-ab5d-f5a4491c1fb3","weight":2},{"event_id":7342,"event_guid":"88474e85-c77c-466e-9351-d306b620f495","weight":4},{"event_id":7345,"event_guid":"a04f9f57-2046-4b50-b6da-4154bc0aa375","weight":2},{"event_id":7352,"event_guid":"cb6ed95d-a208-438f-8ea5-a16916a8a89e","weight":2},{"event_id":7354,"event_guid":"fe017cb4-5ec9-47a7-be7a-6eef09e06581","weight":2}]}]}
