Eine Reise, in eine Zeit, als man zum Telefonieren noch in eine Telefonzelle gehen und dort so komische Plastekarten in das Telefon stecken musste.\nEs ist eine Zeitreise in vielerlei Hinsicht. Hauptsächlich soll es darum gehen, wie sich die Telefonkarten entwickelten und wie sie (in verschiedenen Ländern) funktionierten. Allerdings ergab sich aus den Recherchen auch eine Reise in das Internet der 90er Jahre.\nIch werde zeigen, was die Karten für Daten beinhalten und wie man sie heute noch auslesen kann, um damit die Frage zu beantworten: \"Ist da noch was drauf?\"\nDabei gehe ich auch auf verschiedene Hardware und deren Programmierung ein.\n\nLicensed to the public under https://creativecommons.org/licenses/by/4.0/de/","original_language":"deu","persons":["mizi"],"tags":["580","2025","ds25","Technik","Henny-Brenner-Saal","ds25-deu","Day 2"],"view_count":237,"promoted":false,"date":"2025-09-20T11:15:00.000+02:00","release_date":"2025-09-20T00:00:00.000+02:00","updated_at":"2026-04-05T00:30:06.518+02:00","length":1977,"duration":1977,"thumb_url":"https://static.media.ccc.de/media/events/datenspuren/2025/580-2c35f16e-929e-509a-a527-34423d91a913.jpg","poster_url":"https://static.media.ccc.de/media/events/datenspuren/2025/580-2c35f16e-929e-509a-a527-34423d91a913_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/datenspuren/2025/580-2c35f16e-929e-509a-a527-34423d91a913.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/datenspuren/2025/580-2c35f16e-929e-509a-a527-34423d91a913.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ds25-580-7816-ist-da-noch-was-drauf","url":"https://api.media.ccc.de/public/events/2c35f16e-929e-509a-a527-34423d91a913","conference_title":"Datenspuren 2025","conference_url":"https://api.media.ccc.de/public/conferences/DS2025","related":[],"recordings":[{"size":180,"length":1977,"mime_type":"video/webm;codecs=av01","language":"deu","filename":"ds25-580-deu-7816_-_Ist_da_noch_was_drauf_av1-hd.webm","state":"new","folder":"av1-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2025-09-21T01:59:02.072+02:00","recording_url":"https://cdn.media.ccc.de/events/datenspuren/2025/av1-hd/ds25-580-deu-7816_-_Ist_da_noch_was_drauf_av1-hd.webm","url":"https://api.media.ccc.de/public/recordings/91455","event_url":"https://api.media.ccc.de/public/events/2c35f16e-929e-509a-a527-34423d91a913","conference_url":"https://api.media.ccc.de/public/conferences/DS2025"},{"size":62,"length":1976,"mime_type":"video/mp4","language":"deu","filename":"ds25-580-deu-7816_-_Ist_da_noch_was_drauf_sd.mp4","state":"new","folder":"h264-sd","high_quality":false,"width":720,"height":576,"updated_at":"2025-09-21T01:58:55.295+02:00","recording_url":"https://cdn.media.ccc.de/events/datenspuren/2025/h264-sd/ds25-580-deu-7816_-_Ist_da_noch_was_drauf_sd.mp4","url":"https://api.media.ccc.de/public/recordings/91454","event_url":"https://api.media.ccc.de/public/events/2c35f16e-929e-509a-a527-34423d91a913","conference_url":"https://api.media.ccc.de/public/conferences/DS2025"},{"size":18,"length":1976,"mime_type":"audio/opus","language":"deu","filename":"ds25-580-deu-7816_-_Ist_da_noch_was_drauf_opus.opus","state":"new","folder":"opus","high_quality":false,"width":0,"height":0,"updated_at":"2025-09-21T01:58:06.357+02:00","recording_url":"https://cdn.media.ccc.de/events/datenspuren/2025/opus/ds25-580-deu-7816_-_Ist_da_noch_was_drauf_opus.opus","url":"https://api.media.ccc.de/public/recordings/91453","event_url":"https://api.media.ccc.de/public/events/2c35f16e-929e-509a-a527-34423d91a913","conference_url":"https://api.media.ccc.de/public/conferences/DS2025"},{"size":30,"length":1977,"mime_type":"audio/mpeg","language":"deu","filename":"ds25-580-deu-7816_-_Ist_da_noch_was_drauf_mp3.mp3","state":"new","folder":"mp3","high_quality":false,"width":0,"height":0,"updated_at":"2025-09-21T01:58:02.721+02:00","recording_url":"https://cdn.media.ccc.de/events/datenspuren/2025/mp3/ds25-580-deu-7816_-_Ist_da_noch_was_drauf_mp3.mp3","url":"https://api.media.ccc.de/public/recordings/91452","event_url":"https://api.media.ccc.de/public/events/2c35f16e-929e-509a-a527-34423d91a913","conference_url":"https://api.media.ccc.de/public/conferences/DS2025"},{"size":178,"length":1976,"mime_type":"video/mp4","language":"deu","filename":"ds25-580-deu-7816_-_Ist_da_noch_was_drauf_hd.mp4","state":"new","folder":"h264-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2025-09-20T15:39:00.326+02:00","recording_url":"https://cdn.media.ccc.de/events/datenspuren/2025/h264-hd/ds25-580-deu-7816_-_Ist_da_noch_was_drauf_hd.mp4","url":"https://api.media.ccc.de/public/recordings/91415","event_url":"https://api.media.ccc.de/public/events/2c35f16e-929e-509a-a527-34423d91a913","conference_url":"https://api.media.ccc.de/public/conferences/DS2025"}]}
