After a short introduction about software freedom on Android and Custom ROMs, I will demonstrate the Free-Software-App-Repository "F-Droid" with its anarchic and anti-censorship features. But as F-Droid offers you access to hundreds of Free-Software-apps and the sheer amount can be overwhelming in the beginning, in a next step I will also come up with the 10 or so most important apps (IMHO!). F-Droid is a Free-Software-App-only repository for Android systems and every Android-based fork and a powerful client that is designed to be resilient against surveillance and censorship. For its competitive character, F-Droid is not available via other "app stores" (like Google Play). You have to download it via your browser once but then it is easy to install and easy to use - and without the need for any account! Once installed, F-Droid offers you access to hundreds of Free-Software-apps in compiled form and their sources. It also allows you to share (your) apps in mulitple ways, including offline methods and via onion repositories. You can add your own Free-Software-project to the official F-Droid catalogue or even set-up your own repositories and offer access via F-Droid. Unfortunately, F-Droid misses any kind of rating system, so the sheer amount of available Free-Software-apps can be overwhelming in the beginning. So, after a short introduction about software freedom on Android and Custom ROMs, I will demonstrate F-Droid with its anarchic and anti-censorship features. Next, I will come up with the 10 or so most important apps (IMHO!). **Update:** [Slides by Erik Albers, CC-BY-SA](https://web.3rik.cc/Nextcloud13/index.php/s/zRqYoA3TQb97mrP) about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/UFZYAS/

Die andauernde Kriminalisierung humanitärer Hilfe hat auch in diesem Jahr unsere Arbeit massiv erschwert, Menschenleben gekostet und die europäische Abschottungspolitik vorangetrieben. In diesem Talk geben wir einen Überblick darüber, welche Auswirkungen die Kriminalisierung humanitärer Hilfe haben kann und was im kommenden Jahr zu erwarten ist. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/WCXEXU/

Bea gibt einen Überblick über den aktuellen Stand zur Störerhaftung, wie es den Abmahnungen geht und was uns der Gesetzgeber neues bietet. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/Q7XT7M/

Das Independent Solar Energy Mesh System (ISEMS) knüpft an den Freifunk-OpenMPP-Tracker an. Das System (Lua-Tool, Integration in Luci, Mikrocontroller-Firmware für den OpenMPPT, Web-App) soll es für Nicht-Experten einfacher machen, ihrer eigene drahtlosen Freifunk-Kommunikationsinfrastruktur unabhängig vom Stromnetz zu betreiben. ISEMS überwacht u.a. den Batteriestand, die Batterietemperatur und die Energiedaten des Moduls und bietet Strategien zum Energiesparen. Mit der ISEMS-Software können Benutzer eine Übersicht einsehen, wie ihre Solarknoten arbeiten. Die Web-App zeigt eine Übersicht aller Knoten sowie eine Checkliste für die einzelnen Knoten. Wenn etwas aus dem Ruder läuft, liefert sie Warnungen und Hinweise zur Fehlerbehebung. Dauer: 20 Minuten für unsere Präsentation mit 10 Minuten für Q + A Zusätzliche Infos / Links / Referenzen: http://isems.de https://www.youtube.com/watch?v=BxFpY2tsPtU https://wiki.freifunk.net/Freifunk-MPP-Tracker about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/EGJW3F/

FF-TNG aims at regrowing a local FF based network community by -on the one hand- going back to the 90's "Bürgernetze" Idea of free communication with others, (focus on VOIP, SMS, Chat, mail) but also by enabling the individual community member to offer services to others and the world (e.g. via DNS zone delegation to individual nodes). For true autonomy we envisage to not only use WIFI and VPN links but also include LORA-based communication to connect local nodes for low bitrate communication (chat, sms). A small group of FF-Munich people is currently developing a concept called FF-TNG "Freifunk - The Next Generation". It came about after FFMUC had grown rapidly but a vast majority of FFMUC nodes is only using FF as a cheap pseudo-VPN gateway to the internet and after the rapid growth has put BATMAN to its limits making FF an only 'so-so' experience. The concept aims at regrowing a local network community by -on the one hand- going back to the 90's "Bürgernetze" Idea of free communication with others, (e.g. VOIP, SMS, Chat) and -on the other hand- also by enabling the individual community member to offer services to others and the world (i.e. including DNS zone delegation to individual nodes and ipv6). For parts of the mesh we are looking at Babel. To get to a truly wide ranging individual network our concept includes LORA based communication for low-bitrate communication (Chat, SMS) to reach locations not reachable by simple 2.4 or 5GHz WIFI nodes. The talk will be a ride through our first concept of how we think communication power can be put back to people so they can control their communication network. We hope for comments and input from the community - also of the kind "das kannste schon so machen, aber dann isses halt kacke" about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/AVFU8A/
