Allerdings sind komplexe Shell-Scripts schwer wartbar und haben diverse Tücken. Python bietet eine Alternative als \"echte\" Programmiersprache, die weiterhin kompakte und schnell erstellbare Scripts ermöglicht.\n\nDer Vortrag zeigt anhand von Bespielen, wie sich mit wenigen Zeilen Python-Code Funktionalitäten von Shell-Scripts nachbauen lassen.\n\n- Standardbefehlen wie cp, rm, grep, find, tail, head etc. nachbauen.\n- Externe Programme aufrufenderen Ausgabe weiterverarbeiten.\n- Befehlszeilen-Optionen auswerten und prüfen.\n- Umgebungsvariablen verwenden.\n- Fehler behandeln.\n\nGegenüber klassischen Shell-Scripts sind Python-Programme gut lesbar und damit wartbar, können bei steigender Komplexität in mehrere Module aufgeteilt werden, verwenden zur Fehlerbehandlung Exception-Handling statt leicht ignorierbaren Exit-Codes, sind plattformunabhängig und können für \"low level\" Operationen wie String-Transformationen oder Datumsfunktionen auf eine umfangreiche Standardbibliothek zugreifen.\n\nDabei erhalten sie die großen Vorteil von Shell-Scripts: sie sind schnell geschrieben und kompakt.","original_language":"deu","persons":["Thomas

vor, ihr fährt nach Kroatien auf Urlaub und das smarte Schloss eurer gemieteten Ferienwohnung streikt. Oder ihr arbeitet in einem Hochhaus, und der Lift braucht gerade, als ihr ins 30. Stockwerk fahren wollt, ein Update. In der neuen, smarten Welt kann vieles passieren, woran zuerst einmal keiner denkt - außer Schriftstellern mit ihrer unendlichen Vorstellungskraft. Die besten Ausschnitte aus \"Smart Lies - alles smart?\" in einer Lesung.\n\nBeim „Internet der Dinge“ liegen Wirklichkeit und Utopie nah beieinander: Die ersten vernetzte Kühlschränke, die Spam-Mails verschickt haben, gab es bereits im Jahr 2014. Vernetzte Autos, deren Bremsen am selben System hingen wie der Autoradio, wurden 2015 geknackt und aus der Ferne manipuliert. 2016 folgten Smart-TVs. Diese Geschichten hätten auch Science-Fiction-Autoren nicht besser hingekriegt! Oft sind es aber auch weniger spektakuläre Dinge, wie IP-Überwachungskameras, Thermostate, Feuermelder, Netzwerkdrucker oder WLAN-Router, die das “Internet der Dinge” zu einer wahren Gefahr für das gesamte Internet machen.\n\nDie Anthologie \"Smart Lies - Alles smart!\", die Barbara Wimmer zusammen mit Günther Friesinger von monochrom veröffentlicht hat, beschäftigt sich daher mit dem Thema „Alles smart, oder?“ – Smarte Geräte sind oft gar nicht so intelligent wie sie auf den ersten Blick scheinen. Oft sind es auch einfach kleine Spionagegeräte und wir geben damit zudem immer häufiger die Herrschaft über unsere eigenen Entscheidungen ab. Eine App hier, die uns die Wassertemperatur verrät, einen App da, die unsere Heizung aufdreht. Doch was passiert eigentlich, wenn wir uns auf die Aussage der digitalen Assistentin Alexa verlassen, die sagt, dass es draußen schneit, statt einfach selbst aus dem Fenster zu sehen und und dabei festzustellen, dass die Sonne scheint?\n\nBarbaras Geschichten drehen sich etwa um die Update-Problematik bei Alltagsgegenständen sowie darum, wie böse Ferien enden können, wenn ein smartes Schloss die Urlaubsfreuden verdirbt. Beide Geschichten sind angelehnt an Fakten - ergo, die Grundidee ist nicht erfunden, nur die Geschichten rundherum. Die besten Auszüge bekommt ihr hier im Rahmen einer Lesung präsentiert.","original_language":"deu","persons":["Barbara Wimmer"],"tags":["glt18","329","Community"],"view_count":116,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-06-13T08:45:02.239+02:00","length":1815,"duration":1815,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/329-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/329-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/25b036d4-ae45-4173-9806-65611e90a78c-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/25b036d4-ae45-4173-9806-65611e90a78c-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_329_-_de_-_g_ap147_004_-_201804280955_-_smart_lies_-_alles_smart_-_barbara_wimmer","url":"https://api.media.ccc.de/public/events/25b036d4-ae45-4173-9806-65611e90a78c","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":10},{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":9},{"event_id":5258,"event_guid":"e3e99d32-545e-476e-b92e-c9a7a2915e2c","weight":3},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":6},{"event_id":5264,"event_guid":"a957ad86-6cbc-4df6-a3e7-2dada4988d1a","weight":4},{"event_id":5266,"event_guid":"a4e7700f-8839-42ef-acfd-7d26af0463ef","weight":8},{"event_id":5268,"event_guid":"d154dae1-b03c-4533-8c15-b882ffa5ca3a","weight":8},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":9},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":6},{"event_id":5275,"event_guid":"27267d09-859b-4ebf-a779-63145861c816","weight":4},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":9},{"event_id":5281,"event_guid":"b5eddb28-67cd-4d29-838f-b5b70fc77d65","weight":5},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":7},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":6},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":8}]},{"guid":"f55c60ce-85d5-457f-a6c1-74317ea72bdd","title":"wem gehört das, was ich programmiere?","subtitle":null,"slug":"GLT18_-_348_-_de_-_g_ap147_004_-_201804281100_-_wem_gehort_das_was_ich_programmiere_-_sorciere1024","link":"https://c3voc.de","description":"Wem meine Programme gehören, hängt davon ab, welche Maßnahmen ich ergreife und wie mein Dienstvertrag aussieht.

and offer reasons on why it is an underestimated tool for high quality software engineering.\n\nCode review is often considered something that is more theory than practice, consuming time and resources without proportional gain.\n\nTeams, especially in a work context, are sometimes opposed to based on misconceptions around its effectiveness and impact on the team or climate.\n\nThe talk therefore also looks at specific examples on successful usage of code review in collaborative development environments.\n","original_language":"eng","persons":["Kevin

Ein kurzes Beispiel für den Workflow, wie er vom Vortragenden verfolgt wird, inklusive Bearbeitung eines Bildbeispiels runden die Präsentation ab.","original_language":"deu","persons":["Dietmar Thaler"],"tags":["glt18","320","Anwendungen"],"view_count":676,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-06-10T12:15:06.418+02:00","length":2299,"duration":2299,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/320-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/320-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/0bf761ab-9746-44c3-8bd0-a1239da75c17-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/0bf761ab-9746-44c3-8bd0-a1239da75c17-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_320_-_de_-_g_ap147_006_-_201804281155_-_darktable_-_der_erfahrungsbericht_eines_fotoamateurs_-_dietmar_thaler","url":"https://api.media.ccc.de/public/events/0bf761ab-9746-44c3-8bd0-a1239da75c17","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":17},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":18},{"event_id":5259,"event_guid":"1ab2ef24-a3cd-4c11-bb81-c7ff472b8d61","weight":1},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":17},{"event_id":5265,"event_guid":"a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65","weight":12},{"event_id":5269,"event_guid":"0e882675-e564-4d14-a2eb-251dc2c68783","weight":3},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":29},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":22},{"event_id":5274,"event_guid":"c38c514b-99f4-4906-a0e5-189df72dbd9e","weight":17},{"event_id":5279,"event_guid":"baef3860-9786-4917-a46c-5ddd4fdac22e","weight":13},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":24},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":19},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":35},{"event_id":5287,"event_guid":"5d5e3275-0f1a-41ae-a1ad-a98ba66f1390","weight":18},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":30}]},{"guid":"d120538e-817a-420b-9be2-a5088429f439","title":"Linux für die Massen","subtitle":"Wie ich Otto Normalverbraucher zu Linux bringe.","slug":"GLT18_-_333_-_de_-_g_ap149_112_-_201804281740_-_linux_fur_die_massen_-_peter_linzbauer","link":"https://c3voc.de","description":"Es gibt viele Gründe freie Software einzusetzen.

Lasst uns gemeinsam einen Blick auf ripgrep, exa, fzf, ip und Co. werfen.","original_language":"deu","persons":["leyrer"],"tags":["glt18","327","Admin"],"view_count":967,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-06-24T23:45:04.064+02:00","length":2713,"duration":2713,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/327-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/327-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/1e7ca9c3-609b-4c73-bf25-60501cba6791-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/1e7ca9c3-609b-4c73-bf25-60501cba6791-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_327_-_de_-_g_ap147_005_-_201804281100_-_moderne_kommandozeilen_werkzeuge_-_leyrer","url":"https://api.media.ccc.de/public/events/1e7ca9c3-609b-4c73-bf25-60501cba6791","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5240,"event_guid":"39474e46-4733-2020-2020-202020202020","weight":19},{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":77},{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":23},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":72},{"event_id":5257,"event_guid":"d23abae3-6fb3-4de5-916e-d7caf96cec6e","weight":11},{"event_id":5261,"event_guid":"f55c60ce-85d5-457f-a6c1-74317ea72bdd","weight":13},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":25},{"event_id":5265,"event_guid":"a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65","weight":15},{"event_id":5266,"event_guid":"a4e7700f-8839-42ef-acfd-7d26af0463ef","weight":11},{"event_id":5267,"event_guid":"5ef135ce-0d27-4ca1-82f6-b476d4ac5420","weight":15},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":56},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":27},{"event_id":5274,"event_guid":"c38c514b-99f4-4906-a0e5-189df72dbd9e","weight":62},{"event_id":5275,"event_guid":"27267d09-859b-4ebf-a779-63145861c816","weight":11},{"event_id":5279,"event_guid":"baef3860-9786-4917-a46c-5ddd4fdac22e","weight":21},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":26},{"event_id":5281,"event_guid":"b5eddb28-67cd-4d29-838f-b5b70fc77d65","weight":10},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":27},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":33},{"event_id":5287,"event_guid":"5d5e3275-0f1a-41ae-a1ad-a98ba66f1390","weight":33},{"event_id":5288,"event_guid":"37531db5-97a0-4e99-8907-16133274b221","weight":13},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":47},{"event_id":5292,"event_guid":"0bf761ab-9746-44c3-8bd0-a1239da75c17","weight":10},{"event_id":5355,"event_guid":"8afc16c2-d76a-53f6-85e4-90494665835d","weight":15},{"event_id":5393,"event_guid":"faea7134-21b2-5264-9e02-a8706b63e7fc","weight":19},{"event_id":7147,"event_guid":"5fe8bbbe-116b-5d42-ad17-90208755ce30","weight":13}]},{"guid":"baef3860-9786-4917-a46c-5ddd4fdac22e","title":"The Advantages of File Name Conventions and Tagging","subtitle":"Tagging, Offline, Decentral, Plattform-independent","slug":"GLT18_-_321_-_en_-_g_ap147_004_-_201804281550_-_the_advantages_of_file_name_conventions_and_tagging_-_karl_voit","link":"https://c3voc.de","description":"Most users do not have a clear strategy for managing their files.

Especially medicine and language students use it frequently for long-term memorization. Given a set of vocabulary, how can you remember it with little effort and long-term? Anki is the most popular representative of SRS (Spaced Repetition Software). This underlying algorithm determines when the next review should take place. Psychological studies show that this method works well.\n\nIn 2017, I had to study Japanese vocabulary and Kanji in a quite limited amount of time. In this situation, I began to discover memorization software and improved my studying skills. Anki is the most popular SRS representative (Spaced Repetition Software) and some free software under the GNU AGPL v3 (Desktop and Android client).\n\nSpaced Repetition is a learning technique similar to the Leitner system. Digital flashcards have two sides: a question and an answer. In a review, the user answers one question after another. In case of Anki, you tap how good you remembered the answer. The SRS algorithm schedules the next review based on your previous rating. In case of a good score, the gaps between reviews increase exponentially.\n\nIn this talk, I will present my usecase, the interface and its associated projects.","original_language":"eng","persons":["Lukas Prokop"],"tags":["glt18","355","Anwendungen"],"view_count":160,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-04-24T01:00:03.848+02:00","length":3065,"duration":3065,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/355-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/355-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/1487ac08-c0e8-4d2a-ad2d-8ec70a2278f0-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/1487ac08-c0e8-4d2a-ad2d-8ec70a2278f0-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_355_-_en_-_g_ap149_112_-_201804281645_-_don_t_forget_to_remember_-_lukas_prokop","url":"https://api.media.ccc.de/public/events/1487ac08-c0e8-4d2a-ad2d-8ec70a2278f0","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":9},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":7},{"event_id":5262,"event_guid":"1e7ca9c3-609b-4c73-bf25-60501cba6791","weight":8},{"event_id":5266,"event_guid":"a4e7700f-8839-42ef-acfd-7d26af0463ef","weight":6},{"event_id":5268,"event_guid":"d154dae1-b03c-4533-8c15-b882ffa5ca3a","weight":5},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":5},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":6},{"event_id":5274,"event_guid":"c38c514b-99f4-4906-a0e5-189df72dbd9e","weight":5},{"event_id":5279,"event_guid":"baef3860-9786-4917-a46c-5ddd4fdac22e","weight":7},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":3},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":6},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":5},{"event_id":5290,"event_guid":"1574d0a2-4708-4dd9-9d70-9b75cd075639","weight":5},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":5},{"event_id":5292,"event_guid":"0bf761ab-9746-44c3-8bd0-a1239da75c17","weight":9}]},{"guid":"bf1b743d-4a17-4c6a-957a-87dbf893ed21","title":"practical open hamradio","subtitle":null,"slug":"GLT18_-_318_-_de_-_g_ap149_112_-_201804281445_-_practical_open_hamradio_-_oe6rke","link":"https://c3voc.de","description":"practical insights into open source, open hardware amateur radio projects\n\nAuch die Community der Funkamateure wird immer mehr von dem Geist \"open\" infiziert.

Österreich steht also vor einer möglichen Abmahnwelle in der jeder jeden klagen könnte.\n\nWas dies bedeutet und wie Inside Politics auf einen Feststellungsbescheid der Medienbehörde nun reagiert, erklären wir in unserem Beitrag \"Vermintes YouTube 2.0\".","original_language":"deu","persons":["Sivic"],"tags":["glt18","298","Community"],"view_count":75,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-06-04T17:15:05.049+02:00","length":1984,"duration":1984,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/298-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/298-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/e3e99d32-545e-476e-b92e-c9a7a2915e2c-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/e3e99d32-545e-476e-b92e-c9a7a2915e2c-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_298_-__-_g_ap149_112_-_201804281005_-_vermintes_youtube_2_0_-_sivic","url":"https://api.media.ccc.de/public/events/e3e99d32-545e-476e-b92e-c9a7a2915e2c","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5253,"event_guid":"25b036d4-ae45-4173-9806-65611e90a78c","weight":3},{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":5},{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":8},{"event_id":5260,"event_guid":"5c28a69e-02ed-4e3e-bf26-9046cf5fde11","weight":6},{"event_id":5262,"event_guid":"1e7ca9c3-609b-4c73-bf25-60501cba6791","weight":5},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":6},{"event_id":5270,"event_guid":"5ae52c55-6447-45f8-9d13-36d15303fffe","weight":3},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":6},{"event_id":5276,"event_guid":"4a92dabf-87ab-455c-89a9-ef3930924da0","weight":4},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":5}]},{"guid":"5ef135ce-0d27-4ca1-82f6-b476d4ac5420","title":"Lightning Talks","subtitle":"5 min Kurzvorträge","slug":"GLT18_-_378_-__-_g_ap147_005_-_201804281245_-_lightning_talks","link":"https://c3voc.de","description":"Spontane Einreichungen noch möglich.

Neben unseren Releases openSUSE Leap und openSUSE Tumbleweed bietet das openSUSE-Projekt zusätzlich Tools wie OBS, openQA und YaST an. Es gibt auch noch weitere Sub-Projekte, wie z. B.

Dieser Vortrag zeigt die wichtigsten Neuerungen und deren Vorteile.\n\nSeit SQL-92 wurde der SQL-Standard fünf mal überarbeitet. Die aktuelle Version ist aus dem Jahr 2016.\n\nDabei ist insbesondere nennenswert, dass das Credo der rein relationalen Algebra bereits mit SQL:1999 aufgegeben wurde. Seither wurde SQL stetig um nicht-relationale Funktionen erweitert. Die Spanne reicht dabei von Dokumentformaten wie XML oder JSON bis zu statistischen Funktionen wie dem median.\n\nIn diesem Vortrag löse ich einige gängige Probleme mit SQL-92 und modernem SQL, um den Unterschied deutlich zu machen. Natürlich zeige ich auch, welche Datenbanken diese Funktionen bereits unterstützen.","original_language":"deu","persons":["Markus Winand"],"tags":["glt18","359","Anwendungen"],"view_count":342,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-05-20T18:45:04.400+02:00","length":2746,"duration":2746,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/359-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/359-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_359_-_de_-_g_ap147_004_-_201804281350_-_modernes_sql_in_open-source_datenbanken_-_markus_winand","url":"https://api.media.ccc.de/public/events/a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":13},{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":2},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":19},{"event_id":5259,"event_guid":"1ab2ef24-a3cd-4c11-bb81-c7ff472b8d61","weight":1},{"event_id":5261,"event_guid":"f55c60ce-85d5-457f-a6c1-74317ea72bdd","weight":1},{"event_id":5262,"event_guid":"1e7ca9c3-609b-4c73-bf25-60501cba6791","weight":15},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":14},{"event_id":5269,"event_guid":"0e882675-e564-4d14-a2eb-251dc2c68783","weight":2},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":20},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":22},{"event_id":5274,"event_guid":"c38c514b-99f4-4906-a0e5-189df72dbd9e","weight":20},{"event_id":5276,"event_guid":"4a92dabf-87ab-455c-89a9-ef3930924da0","weight":1},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":16},{"event_id":5281,"event_guid":"b5eddb28-67cd-4d29-838f-b5b70fc77d65","weight":1},{"event_id":5282,"event_guid":"c32f7e51-6c54-490b-bd4d-6745aca48f51","weight":25},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":18},{"event_id":5287,"event_guid":"5d5e3275-0f1a-41ae-a1ad-a98ba66f1390","weight":2},{"event_id":5288,"event_guid":"37531db5-97a0-4e99-8907-16133274b221","weight":2},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":27}]},{"guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","title":"X-Factor: Das Unfassbare -

Zuerst wird ein Blick auf die Elektronik und Sensoren vom Raspberry Pi Workshop vom Vortag geworfen. Dann werden weitere Projekte rund um Hausautomation und Überwachung vorgestellt, sowie über den Status früherer Projekte berichtet. Zum Schluss wird noch das Thema Retrogaming mit der Open Source Software Lakka erörtert und vorgeführt.\n\nBei Raspberry Pi Workshop 2018 lag der Fokus auf kleine Elektronik Projekte mit einfachen Sensoren. Es gab Beispiele  für den Lufttemperatur und Feuchte Sensor DHT22, dem Entfernungssensor HC-SR04 und den Bewegungssensor HC-SR501. \nDer nächsten Teil des Vortrags beschäftigt sich mit weiteren ausgewählten Projekten rund um Hausautomation und Sensorik. Es wird über den Fortschritt einiger im Vorjahr vorgestellter Projekte berichtet. \n2017 war das Jahr der Retrokonsolen, Nintendo NES Classic Mini, Super Nintendo Classic Mini, SEGA Megadrive Flashback HD, The C64 Mini und Atari Flashback kamen auf den Markt. Doch wer sich ein wenig mit Comptertechnik und Linux auskennt, kann sehr einfach und günstig eine All -in-One Retrokonsole im Eigenbau herstellen. Was man wissen muss und wie das geht erfahrt man im Vortrag. Natürlich wird auch ein Live-System auf Basis von Lakka und dem Raspberry Pi vorgeführt.","original_language":"deu","persons":["Martin Strohmayer","Manfred

Es ist Mandanten- und Multi-Instanz-fähig. Dank der modularen Struktur lässt sich privacyIDEA schnell und leicht anpassen. Es greift nicht invasiv auf bestehende Benutzerquellen wie LDAP, AD, SQL-Datenbanken, SCIM-Dienste oder Flatfile zu und fügt sich somit in Ihre bestehenden Workflows ein. Über eine einfache REST-ähnliche API kann es erweitert, automatisiert oder Ihren Arbeitsabläufen zugänglich gemacht werden.\n\nprivacyIDEA ist das Open Source Mehr-Faktor-Authentifizierungs-System, das on Premise läuft. In diesem Vortrag wird gezeigt, wie es in das eigenen Netzwerk integriert wird.\n\nFür größere Installation interessant sind die Möglichkeiten, einer sanften Migration von beliebigen alten, proprietären Authentifizierungsprodukten.

I'll show what hardware and software I used to build a wordclock. The talk is aimed at anyone who is interested in a little soldering and programming with Micropython. As all components are readily available. The project is perfect for advanced beginners who want to learn how to make their own electronics projects.\n\nMost clocks you use today are bought. Many are not even your own, but tell you the time when passing by. How many did you build yourself? \nAs a software engineer I opted to build an electronic clock that shows the time in a letter matrix (generally known as word clock). In this talk we will look at how this building process looked and what I used to build it.

Die Lösung: Ein sicheres privates Mailsystem mit OpenSource Software. Dieser Vortrag zeigt, was es zu beachten gilt, damit das Projekt \"Mailserver\" nicht vorschnell im Frust endet.\n\nInteressierte Nutzer, die bereits grundlegende Erfahrung mit der Administration von Linux Server haben, erfahren wie durch die Verwendung diverser Open Source Tools ein sicheres Linux-basierendes Mailsystem für die private Nutzung geschaffen werden kann. Hierbei werden die Vorteile und Nachteile eines privaten, self-hosted Mailsystems erläutert, die konzeptionellen Grundlagen erklärt, geschildert was es im Vorfeld zu beachten gilt und wie ein solches System aufgesetzt und konfiguriert wird. Dabei wird der Fokus stets auf Sicherheit und Privacy gelegt. Darüber hinaus wird verdeutlicht, wie wichtig ein sauber konfigurierter Spamfilter (SpamAssassin oder rspamd) am Server ist, um nicht im Spam-Chaos zu versinken. Die Vortragenden geben best-practice Ratschläge aus ihrer eigenen Erfahrung und weisen auch auf klassische Anfängerfehler hin. Anhand zweier Szenarien wird gezeigt, wie ein klassischer Mailserver - bestehend aus Postfix, Dovecot und Roundcube - aufgebaut ist und wie sich eine komplette Groupware-Lösung, basierend auf Kopano und Z-Push, realisieren lässt. Abgerundet wird der Vortrag mit zusätzlichen allgemeinen Hinweisen zu relevanten Technologien und Protokollen rund um den Betrieb eines Mailservers (nötige DNS Records, SPF, DKIM, DMARC, …).","original_language":"deu","persons":["Patrick Lesky","Wolfgang Berger"],"tags":["glt18","363","Admin"],"view_count":910,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-06-26T12:00:07.453+02:00","length":2957,"duration":2957,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/363-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/363-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/f636e390-cad4-47f7-873d-7a23431fed16-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/f636e390-cad4-47f7-873d-7a23431fed16-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_363_-_de_-_g_ap147_005_-_201804281645_-_privater_mailserver_aber_sicher_-_patrick_lesky_-_wolfgang_berger","url":"https://api.media.ccc.de/public/events/f636e390-cad4-47f7-873d-7a23431fed16","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":25},{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":14},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":28},{"event_id":5257,"event_guid":"d23abae3-6fb3-4de5-916e-d7caf96cec6e","weight":15},{"event_id":5260,"event_guid":"5c28a69e-02ed-4e3e-bf26-9046cf5fde11","weight":10},{"event_id":5262,"event_guid":"1e7ca9c3-609b-4c73-bf25-60501cba6791","weight":27},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":20},{"event_id":5265,"event_guid":"a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65","weight":18},{"event_id":5266,"event_guid":"a4e7700f-8839-42ef-acfd-7d26af0463ef","weight":22},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":45},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":23},{"event_id":5274,"event_guid":"c38c514b-99f4-4906-a0e5-189df72dbd9e","weight":47},{"event_id":5275,"event_guid":"27267d09-859b-4ebf-a779-63145861c816","weight":13},{"event_id":5279,"event_guid":"baef3860-9786-4917-a46c-5ddd4fdac22e","weight":17},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":29},{"event_id":5281,"event_guid":"b5eddb28-67cd-4d29-838f-b5b70fc77d65","weight":10},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":28},{"event_id":5287,"event_guid":"5d5e3275-0f1a-41ae-a1ad-a98ba66f1390","weight":34},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":44},{"event_id":5292,"event_guid":"0bf761ab-9746-44c3-8bd0-a1239da75c17","weight":19}]},{"guid":"0f2f4ca6-3784-450b-a3d3-a4e1d275ad5a","title":"Too young to rock'n'roll","subtitle":"Warum Kinder eine Freie-Software-Gemeinschaft brauchen","slug":"GLT18_-_299_-_de_-_g_ap149_112_-_201804281100_-_too_young_to_rock_n_roll_-_dominik_george_-_sascha_kostanyan_-_niels_hradek","link":"https://c3voc.de","description":"Kinder nutzen Software. Doch können sie auch aktiver Teil der FOSS-Gemeinschaft sein? Welche Erfahrungen gibt es? Und was können Projekte tun, um für minderjährige Kontributoren offen zu sein?\n\nKinder wollen und sollen ihre Umwelt mitgestalten. Gerade im IT-Bereich wird das Einstiegsalter in der reinen Nutzung immer geringer. Natürlich gibt es auch freie Software mit einer jungen Zielgruppe, wie z.B. Software im Bildungseinsatz oder Spiele. Der Teckids e.V. ist eine Jugendorganisation rund um freie Software, die Kinder und Jugendliche zu einem aktiven Teil der Freie-Software-Gemeinschaft machen möchte. Warum junge Nutzerinnen und Nutzer auch als Kontributoren willkommen sein sollten, ist der erste Diskussionspunkt. Freie Software lebt darüberhinaus von der Community. Deshalb bemühen sich Projekte, die Hürden für en Einstieg als Kontributor möglichst niedrig zu halten. Plattformen wir GitHub vereinfachen das Einreichen von Bugs und Feature Requests und das Beisteuern von Patches. Doch ein Teil der Community, nämlich Minderjährige, haben es noch immer schwer, an für sie interessanten Projekten mitzuwirken - bspw. an edukativer Software, Spielen u.ä. Welche rechtlichen Hürden moderne Tools aufzwingen und was Projekte tun können, um auch die Jüngsten an Bord zu holen, wollen wir hier erörtern.","original_language":"deu","persons":["Dominik George","Sascha Kostanyan","Niels Hradek"],"tags":["glt18","299","Community"],"view_count":80,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-02-21T22:45:05.403+01:00","length":1688,"duration":1688,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/299-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/299-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/0f2f4ca6-3784-450b-a3d3-a4e1d275ad5a-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/0f2f4ca6-3784-450b-a3d3-a4e1d275ad5a-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_299_-_de_-_g_ap149_112_-_201804281100_-_too_young_to_rock_n_roll_-_dominik_george_-_sascha_kostanyan_-_niels_hradek","url":"https://api.media.ccc.de/public/events/0f2f4ca6-3784-450b-a3d3-a4e1d275ad5a","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":5},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":4},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":4},{"event_id":5264,"event_guid":"a957ad86-6cbc-4df6-a3e7-2dada4988d1a","weight":5},{"event_id":5266,"event_guid":"a4e7700f-8839-42ef-acfd-7d26af0463ef","weight":4},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":7},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":4},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":4},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":4},{"event_id":5288,"event_guid":"37531db5-97a0-4e99-8907-16133274b221","weight":5},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":5}]},{"guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","title":"Pimp up your Heimnetzwerk","subtitle":null,"slug":"GLT18_-_297_-_de_-_g_ap147_006_-_201804281445_-_pimp_up_your_heimnetzwerk_-_bernhard_slash_trummer","link":"https://c3voc.de","description":"Basierend auf meinem aktuellen Heimnetzwerk möchte ich in diesem Vortrag meine Anwendungsfälle vorstellen und Schritt für Schritt den Pfad von der Problemstellung zur Lösung skizzieren.\n\nPS: Es geht NICHT um Heimautomatisierung und IoT.\n\n1.)

Wer stabile IT-Infrastruktur langfristig betreut, muss sich ständig mit- und weiterentwickeln. Welche Best Practices gibt es im Jahr 2018?\n\nDie IT-Branche entwickelt sich ständig weiter, das gilt auch für den modernen IT-Administrator. Wer stabile IT-Infrastruktur langfristig betreut, muss sich ständig mit- und weiterentwickeln. Dabei gilt es einen gesunden Mix aus Kontinuität und innovativen Technologien zu finden, ohne dabei gleich auf jeden Hype aufzuspringen.\n\nVor 20 Jahren gab es kein Konfigurationsmanagement wie man es heute mit etablierten Tools wie Puppet/Chef/Ansible gewohnt ist. Continuous Delivery, Autoscaling, DevOps, Serverless,... sind Konzepte und Praktiken, die wir in dieser Form erst seit - vergleichsweise - wenigen Jahren kennen bzw. praktizieren. Der moderne IT-Administrator redet ganz selbstverständlich von Versionskontrolle, Containern und der Cloud.\n\nNoch nie war der der Betrieb von IT-Infrastruktur auf einem so hohen Niveau wie heutzutage möglich. Gleichzeitig werden die Anforderungen an die Infrastruktur immer komplexer und produktionskritischer. In diesem Vortrag schauen wir uns an, was sich im Laufe der letzten Jahre getan hat und  welche Tools und Konzepte den Sprung vom Hype-Zug in die Sysadmin-Werkzeugkiste geschafft haben.\n\nStichworte: Versionskontrolle, Container, Monitoring, Logging, Metriken, Continuous Delivery, Debugging, APIs","original_language":"deu","persons":["Michael Prokop"],"tags":["glt18","309","Admin"],"view_count":744,"promoted":false,"date":"2018-04-28T00:00:00.000+02:00","release_date":"2018-04-28T02:00:00.000+02:00","updated_at":"2025-05-26T11:45:06.735+02:00","length":1536,"duration":1536,"thumb_url":"https://static.media.ccc.de/media/events/glt/2018/309-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/glt/2018/309-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/glt/2018/c38c514b-99f4-4906-a0e5-189df72dbd9e-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/glt/2018/c38c514b-99f4-4906-a0e5-189df72dbd9e-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/GLT18_-_309_-_de_-_g_ap147_004_-_201804281515_-_best_practices_in_der_it-administration_version_2018_-_michael_prokop","url":"https://api.media.ccc.de/public/events/c38c514b-99f4-4906-a0e5-189df72dbd9e","conference_title":"Grazer Linuxtage 2018","conference_url":"https://api.media.ccc.de/public/conferences/glt18","related":[{"event_id":2612,"event_guid":"d99a2be6-5794-4f41-b293-9262430bdcfc","weight":7},{"event_id":3085,"event_guid":"fe349b93-6f5a-4964-83d0-d9f5c65bb68e","weight":8},{"event_id":5228,"event_guid":"44434a47-4b41-2020-2020-202020202020","weight":10},{"event_id":5229,"event_guid":"53464646-4151-2020-2020-202020202020","weight":7},{"event_id":5240,"event_guid":"39474e46-4733-2020-2020-202020202020","weight":10},{"event_id":5254,"event_guid":"83235eb6-ce2d-4f4d-8124-1d38010a2076","weight":45},{"event_id":5255,"event_guid":"9f891f57-4fc3-4804-9f41-cac1ef55b529","weight":23},{"event_id":5256,"event_guid":"c2474049-40f0-4d92-935e-e22090e3d343","weight":73},{"event_id":5257,"event_guid":"d23abae3-6fb3-4de5-916e-d7caf96cec6e","weight":20},{"event_id":5260,"event_guid":"5c28a69e-02ed-4e3e-bf26-9046cf5fde11","weight":9},{"event_id":5262,"event_guid":"1e7ca9c3-609b-4c73-bf25-60501cba6791","weight":62},{"event_id":5263,"event_guid":"e19ddb1c-2322-4980-9783-eff8a2f6b262","weight":55},{"event_id":5265,"event_guid":"a4b6d7b8-48ae-47e4-a348-ce7ba14fdb65","weight":20},{"event_id":5266,"event_guid":"a4e7700f-8839-42ef-acfd-7d26af0463ef","weight":27},{"event_id":5267,"event_guid":"5ef135ce-0d27-4ca1-82f6-b476d4ac5420","weight":10},{"event_id":5268,"event_guid":"d154dae1-b03c-4533-8c15-b882ffa5ca3a","weight":7},{"event_id":5269,"event_guid":"0e882675-e564-4d14-a2eb-251dc2c68783","weight":22},{"event_id":5270,"event_guid":"5ae52c55-6447-45f8-9d13-36d15303fffe","weight":8},{"event_id":5271,"event_guid":"3af88c8a-b051-4691-9c3e-f518f42ca5d3","weight":97},{"event_id":5273,"event_guid":"065e78a2-c020-4199-ad38-4bea1e62eb15","weight":39},{"event_id":5275,"event_guid":"27267d09-859b-4ebf-a779-63145861c816","weight":11},{"event_id":5279,"event_guid":"baef3860-9786-4917-a46c-5ddd4fdac22e","weight":27},{"event_id":5280,"event_guid":"2fb00fb8-016b-42a0-a2db-742b6fc2dc80","weight":32},{"event_id":5281,"event_guid":"b5eddb28-67cd-4d29-838f-b5b70fc77d65","weight":17},{"event_id":5282,"event_guid":"c32f7e51-6c54-490b-bd4d-6745aca48f51","weight":9},{"event_id":5283,"event_guid":"f636e390-cad4-47f7-873d-7a23431fed16","weight":47},{"event_id":5286,"event_guid":"d120538e-817a-420b-9be2-a5088429f439","weight":32},{"event_id":5287,"event_guid":"5d5e3275-0f1a-41ae-a1ad-a98ba66f1390","weight":35},{"event_id":5288,"event_guid":"37531db5-97a0-4e99-8907-16133274b221","weight":8},{"event_id":5290,"event_guid":"1574d0a2-4708-4dd9-9d70-9b75cd075639","weight":11},{"event_id":5291,"event_guid":"81747e92-2676-40b9-86ff-09869b125d94","weight":85},{"event_id":5292,"event_guid":"0bf761ab-9746-44c3-8bd0-a1239da75c17","weight":17},{"event_id":5393,"event_guid":"faea7134-21b2-5264-9e02-a8706b63e7fc","weight":8},{"event_id":5758,"event_guid":"ef2ff203-e91d-4b8f-90ad-966fe74d5325","weight":9}]},{"guid":"4a92dabf-87ab-455c-89a9-ef3930924da0","title":"Common misconceptions about names and spaces and communities","subtitle":"Diskussionsrunde über die Realnamepflicht der Grazer Linuxtage","slug":"GLT18_-_383_-_de_-_g_ap147_005_-_201804281540_-_common_misconceptions_about_names_and_spaces_and_communities_-_maclemon_-_pascoda_-_rhonda_d_vine_-_florian_flowolf_klien_-_thesix","link":"https://c3voc.de","description":"Diskussionsrunde über die Realnamenpflicht der Grazer Linuxtage\n\nIm Vorfeld der GLT gab es einige Diskussionen rund um die sogenannte \"Realnamenpflicht\" für die Vortragenden.
