+                <p>
+                “Hackers Against Climate Change" originated as a series of <a href="https://events.ccc.de/congress/2018/wiki/index.php/Session%3AHackers_Against_Climate_Change">self-organized sessions at 35c3</a>. In the aftermath members of those sessions started spin offs as mentioned above and local chapters in Siegen, Munich and on the Canary Islands.
+</p>
+<p>
+The local chapter in Siegen initiated the first hacc sessions at 35c3 and afterwards was mainly involved in local activities.
+<p>
+The local chapter CHT hackbase cohosted the 35c3 sessions, hosted the session at 36c3 and cohosted the divoc r2r sessions.
+</p>
+<p>
+Inspired by the activities in Siegen, the Munich chapter started their bi-weekly meetings in May 2019. With the approval to use the name by the initiator of the first sessions on May 13th 2020 we eventually founded the German non-profit organization "<a href="https://muc.hacc.earth">hackers against climate change e.V.</a>" on December 9th 2020. Two members of us were part of the 35c3 sessions. Since then we were active at the CCCamp 2019, 36c3, rC3 and divoc r2r.<br>

+<p>
+Unfortunately conflicts led to a split between the local chapter Munich and CHT hackbase in July 2021.

+# Leitfaden: PCS 2020 zum Thema Datenschutz     
+
+Dadurch, dass die PCS 2020 online stattfindet müssen wir uns auch Gedanken über Datenschutz machen. Dieser Leitfaden kann nicht jeden Fall abdecken und es handelt sich hier nur um Empfehlungen. 
+
+
+
+## Normaler Vortrag 
+
+Sollte der Vortrag wie eine Vorlesung in diesen Zeiten üblich über eine Konferenzplattform stattfinden jedoch ansonsten nicht weiter gestreamed  oder aufgezeichnet werden, reicht meistens ein einfacher Hinweis auf die Datenschutzrichtlinien der Plattform. Dieser sollte vor betreten der Plattform platziert sein. Zum Beispiel an der Stelle an der ihr die Links zu der Vorlesung bewirbt. 
+
+## Aufgezeichneter oder gestreamter Vortrag
+
+Für einen Vortrag der noch anderweitig zugänglich gemacht werden soll müssen noch weitere Vorkehrung getroffen werden. Alle Menschen die in einem solchen Vortrag zu sehen sind müssen **vor der Verarbeitung ihrer Daten** zugestimmt haben. Zuschauer könnt ihr Beispielsweise mündlich darüber aufklären, dass sie in einem Livestream zu sehen sein werden oder was mit der Aufnahme passiert. Außerdem empfiehlt es sich auch an anderer Stelle darauf hinzuweisen. Beispielsweise kann auf der gleichen Folie auf der zur Interaktion aufgerufen wird, auch der Hinweis stehen, dass eine solche aufgezeichnet wird. Wichtig ist das es nicht die Möglichkeit gibt, dass unfreiwillig oder unwissentlich persönliche Daten (z.B. Äußerungen, Namen etc) verarbeitet/veröffentlicht werden. Um sicher zu gehen könnt  empfiehlt sich zu diesem Zweck auch von jedem Teilnehmenden eine Einverständniserklärung unterschreiben zu lassen. Eine weitere Möglichkeit ist es Fragerunden am Ende des Vortrages nicht mit aufzuzeichnen. Bedenkt außerdem auch, dass auch Menschen die erst später der Konferenz beitreten informiert werden müssen. Zum Beispiel im Chat. 
+
+Die Dozierenden solltet ihr außerdem **vorher** darum bitten euch eine Einverständnis Erklärung auszufüllen. 
+
+Beispiele für Einverständniserklärungen findet ihr [hier](events/einverstaendniserklaerung.md).

+# Online-Events
+
+Hier versuchen wir euch eine Sammlung nützlicher Guides für die Durchführung von
+Online Veranstaltungen bereitzustellen.
+
+Typischerweise sind vor jedem Online-Event folgende Fragen zu klären:
+- **Wie können Menschen teilnehmen?**  
+  Meist entweder direkte Teilnahme im Online Meeting, z.B. über Zoom,
+  oder ein Stream, z.B. über YouTube.
+  
+  Das hängt von einigen Faktoren ab, u.a. wie viele Teilnehmer:innen erwartet werden,
+  wie interaktiv das Event sein soll, und wie geschlossen der Raum, in dem es stattfindet.
+  Für Workshops eignen sich Meetings, für Podiumsdiskussion sind vermutlich Streams
+  die bessere Wahl. Vorträge lassen sich auf beide Arten gut umsetzen. Hier ist vermutlich
+  die Teilnehmer:innenzahl und Öffentlichkeit ausschlaggebend.
+
+  Theoretisch geht auch eine Kombination: Die Teilnehmer:innen können dem Meeting direkt
+  beitreten, während es gleichzeitig gestreamt wird. In diesem Fall müsstet ihr aber
+  sicherstellen, dass keine Person das Meeting stören kann und dass keine persönlichen
+  Daten im Stream landen können. Außerdem könnten Zuschauer:innen auf YouTube dann z.B.
+  nicht erfahren, wenn Fragen im Zoom Chat gestellt werden.
+- **Wer kann teilnehemen / braucht es evtl. eine Anmeldung?**  
+  Es ist bei allen Optionen möglich, die Teilnahme so einzuschränken, dass nur Menschen
+  mit den richtigen Zugangsdaten oder dem richtigen Link teilnehemen können.
+  Um diese zu verteilen könnt ihr zum Beispiel eine Anmeldung machen.
+- **Wie sieht die Interaktion mit den Teilnehmer:innen aus?**  
+  Fast alle Tools haben einen Chat, den ihr natürlich verwenden könnt, der aber auch schnell
+  unübersichtlich werden kann. Es kann sich daher lohnen, ein eigenes Tool für die Live-Interaktion
+  zu verwenden. Mehr dazu findet ihr auf der [zugehörigen Seite bei den Tools](tools/live-interaktion.md).
+- **Soll die Veranstaltung aufgezeichnet werden?**  
+  Wenn ja, braucht ihr vermutlich eine [Einverständniserklärung](events/datenschutz.md).

+# **F**requently **A**sked **Q**uestions:
+
+?> Das FAQ ist noch von der letzten PCS, das heißt insb. die Links werden sich vermutlich noch ändern.
+
+## Wie kommt mein Format in den Stream? Wie läuft das ab?
+Das hängt davon ab, was für ein Format es ist bzw. welches Tool ihr verwendet:
+- **Voraufgezeichnete Videos:** 
+  
+  könnt ihr uns einfach über einen Cloud Link (z.B. hier: https://fffutu.re/pcs-lecture-upload)
+  oder einen Link zu einem (ungelisteten) YouTube Video schicken. Bitte gebt uns das Video noch vor Beginn der PCS.
+  
+- **Zoom-Veranstaltungen**: 
+  
+  hier hängt es davon ab, ob ihr das Meeting selbst erstellt habt oder der/die Dozierende.
+  Nur die Person, die das Meeting erstellt hat kann das Livestreaming aktivieren. Wie das geht steht [hier](zoom.md).
+  Ihr bekommt dazu so bald wie möglich die genauen Einstellungen, die ihr da eingeben müsst.
+  Bitte prüft schon im vornherein, ob ihr das in den Einstellungen findet (also ob es bei euch aktiviert ist).
+  
+- **JitSi**: 
+  
+  Für JitSi im Livestream verwenden wir voraussichtlich eine eigene Instanz. Das bedeutet ihr bekommt von uns so bald wie möglich einen Link zu dem JitSi Raum. Dort könnt ihr dann mit zwei Klicks den Stream starten.
+  Mehr Infos dazu kommen so bald wie möglich. Bitte gebt uns unbedingt vorher bekannt, falls mehr als 6 Personen an diesem Meeting teilnehmen werden.
+  
+- **BigBlueButton**: 
+
+  Es tut uns Leid, aber bisher haben wir uns noch nicht mit einem Leitfaden für BigBlueButton beschäftigen können. Deshalb möchten wir euch diesen ausführlichen Leitfaden von HACC (Hackers Against Climate Crisis) wärmstens empfehlen: [Recording a talk with Big Blue Button and obs studio](https://hacc.uber.space/Recording_a_talk_with_Big_Blue_Button_and_obs_studio)
+  
+  <a href="https://www.youtube.com/watch?v=dmryPtz-_ME&feature=youtu.be"><img src="img/faq/tutorial_thumbnail.png"></a>
+
+## Wie kann ich als Dolmer*in teilnehmen?
+
+- **Den Stream empfangen**
+  1. Über Zoom:
+
+     Sie sitzen mit in dem Zoom Meeting, indem der Vortrag abgehalten wird.
+
+  2. Über VLC:
+
+     Sie empfangen den Stream ohne große Verzögerung auf ihren PC.
+
+     <a href="https://www.youtube.com/watch?v=UBJodCpsUI8">Hier finden Sie die Aufzeichnung des entsprechenden Technik-Briefings.</a>
+
+- **Übersetzung einsprechen**
+
+  Dafür müssen Sie dem entsprechenden Mumble Channel beitreten. Den Link erhalten Sie von uns. Als Gebärdensprachendolmetscher*in müssen Sie nur dem richtigen Zoom Meeting beitreten und nichts weiter tun. <a href="https://www.youtube.com/watch?v=UBJodCpsUI8">Hier finden Sie eine Aufgabe des Übersetzerinnen-Briefings.</a>
+
+
+
+## Wir haben keinen Streaming-Account. Könnt ihr uns etwas zur Verfügung stellen?
+
+- **Streaming Accounts eurer Uni:**
+  
+  werden möglicherweise auch euch als Studenten zur Verfügung gestellt. Viele Universitäten haben zahlreiche Zoom Lizenzen erworben, oder betreiben BigBlueButton Instanzen. Informiert euch also, ob ihr auf diese Weise an einen Account kommt.
+  
+- **Streaming Accounts vom Technik Team:**
+  
+  können wir euch zur Verfügung stellen, wenn ihr keine andere Möglichkeit mehr habt. Zurzeit wäre uns es möglich sowohl Zoom, als auch BigBlueButton Instanzen zu stellen. Wir würden die Anzahl der von uns gestellten Instanzen aber gerne in Grenzen halten. Meldet euch dafür im [PCS-Techsupport](https://fffutu.re/pcs-techsupport) auf Telegram.
+
+## Woher bekomme ich Ortsgruppen Zugang zur Website?
+

+
+## Wie kann ich mit Trollen im meinem Online-Event umgehen?
+
+Das wichtigste zuerst: **Don't Feed the Troll!** Negativ auf dein Event einzuwirken ist oft das Ziel von Troll-Angriffen.
+
+Versuche dich deshalb von destruktiven Menschen
+
+-  nicht ablenken zu lassen, 
+- nicht emotional zu reagieren, 
+- und sie nicht in den Fokus zu rücken. 
+
+Verweise als Moderation im Zweifel darauf, nach dem Event weiterzudiskutieren und nicht währenddessen. 
+
+Ansonsten kannst du natürlich technische Hilfsmittel verwenden, wie
+
+- einen Zoom-Warteraum
+- Menschen kicken/bannen
+- die Video/Sprachfunktion für Menschen ausschalten.
+
+Im [Zoom-Leitfaden](zoom.md) findest du dazu einige nützliche Funktionen.
+
+
+
+**Bitte beachte**, dass wir keine Expert*innen im Umgang mit Trollen sind. Wenn ihr ausführliche Informationen sucht, können wir euch folgende Artikel empfehlen:
+
+- [Ratgeber: Konstruktiv auf Internet-Trolle reagieren (Klimafakten.de)](https://www.klimafakten.de/meldung/ratgeber-konstruktiv-auf-internet-trolle-reagieren)
+
+- [Beware of ‘ZoomBombing’: screensharing filth to video calls (TheCrunch.com)](https://techcrunch.com/2020/03/17/zoombombing/?guccounter=1)
+
+
+
+## Wie kann ich mein Online-Event barrierefrei gestalten?
+
+Beim Stichwort Barrierefreiheit kennen wir Möglichkeiten, um folgendes einzubauen:
+
+- **Live-Untertitel** (braucht Menschen die live Mitschreiben, [Tutorial auf zoom.us](https://support.zoom.us/hc/en-us/articles/207279736))
+- **Gebärdesprachendolmetscher*in** (braucht Mensch mit diesem Skill)
+
+Wenn ihr mit Zoom arbeitet wäre beides umsetzbar. Sofern das Teil des Livestreams sein soll, würden wir dann eurem Meeting beitreten und die Untertitel oder den\*die Dolmetscher\*in mit OBS mitschneiden.
+
+**Bitte sagt uns [hier auf Telegram](https://fffutu.re/pcs-techsupport) sobald wie möglich Bescheid, falls ihr das plant!**
