With the Wifi4EU programm the EU is planning to spend 100 million € by 2020 to subsidise a centralized surveillance infrastructure for centers of public life in the EU. The talk will lay out how Wifi4EU is supposed to work both administratively and technically, where there are problems with the later and what is and can be done about it. Slides: https://zenodo.org/record/2527538#.XCUXplxKjIU With the Wifi4EU programm [1] the EU is planning to subsidies the installation of free Wi-Fi with 120 million € until 2020. The installations are planned to be "... free of charge, free of advertising and free from commercial re-use of data. ..." [2] and aim "... to equip every European village and every city with free wireless internet access around the main centres of public life. ..." [1] Unfortunately the technical specifications implemented in the first call on the 7th - 9th of November [3] tell a different story. So far 42 Million € are planned to be spend in a flawed design. Amongst other problems they include: * requirements for a centralized authentification infrastructure - like eduroam [4] (FAQ 23), * inherent IT security problems - embedded snippets in the captive portals [4] (FAQ 26) and * proprietary standards - hotspot 2.0. [4] (FAQ 27) Following a talk at the wireless community weekend in May this year [5] the talk will include: * a short introduction to the programm, * how it came to be, * what happend so far * the implications of the programm * what can be done to fix things. Besides contacting the european comission, several members of the european parlament and Klaus Landefeld of the eco [6] we were able to get members of the german Bundestag to get interested in the issue [7]. This led to a "schriftliche Anfrage" towards the Bundesregierung regarding the GDPR compliance of the authentification infrastructure, the situation is currently evolving. The talk aims to inform about the current state of affairs and hoefully foster a discussion during the congress what can and should be done to prohibit the creation of yet another surveillance infrastructure and what a desirable public Wi-Fi infrastructure should look like. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/DAN8AX/

The majority of Freifunk mesh routers only have 4mb flash and 32mb memory. The talk wants to start a discussion about possibilities and limits for future support of these devices. Lot's of mesh communities and even OpenWrt want to drop support for 4mb flash / 32mb memory devices. Where is the size and memory increase coming from? Can we do it in a different way or do we have to accept defeat? - Forcing OpenWrt to diet: What knobs can we tweak? What gains and tradeoffs can we expect? - A short introduction to ubus over HTTP - Stupid ideas and experiments. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/W9RHXR/

Die 3 Begriffe werden beleutet und Zusammenhänge hergestellt Heute hat sich eindeutig das Internet durchgesetzt und es stellt sich die Frage, wie gehen wir damit um. Die AkteurInnen im Internet sind Menschen oder von Menschen gemachte Programme. Als Grundlage im Internet sollten die nun schon 70 Jahre alten Menschenrechte gelten. Auch im Bildungsbereich verändert das Internet die bisherigen Strukturen unseres Bildungssystems, mMn sogar weltweit. Menschen begegnen sich auf Augenhöhe. Die open infrastructure hilft dabei Bildung für Menschen zugänglich zu machen und Menschen ein selbstbestimmtes Leben führen zulassen. Die "Hierachien im Kopf" werden von dem realistischen Denken "wir sind alle gerade jetzt auf der Oberfläche von Planet Erde auf Augenhöhe" abgelöst. Dies ist der Prozess, den wir gerade in vielen Bereichen unserer Gesellschaft beobachten. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/ELUSFV/

We live in a world of data theft and broken clouds and I believe it is time to decentralize, host at home or a local provider we trust. Nextcloud is an option that can take care of many of your file sync'n'share, chat and document editing needs, and I'll show how and why! The data from many people is floating around on 'clouds', regularly stolen and traded. We need to decentralize, host ourselves or at a large number of small, local providers we can trust! Probably the most used solution for that today is Nextcloud, which through its app ecosystem of almost 200 apps can be extended to do lots of things. With Nextcloud you can sync and share files, access your calendars and contacts, share holiday pictures with your family or play music. But also manage your passwords, track your phone through GPS, draw, read news, chat and have audio/video calls, read mail, manage tasks and much more. The community has developed almost 200 apps that do all that and more, and loads of tutorials on how to install Nextcloud on a Nuc, in a VM, on a raspberry Pi and more. If self-hosting isn't realistic for you, we have Simple Signup which sets you up at a Nextcloud hosting provider close to you in a few clicks. This talk is for people not yet familiar with Nextcloud! about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/KB9VRZ/

Global NGO Players vs. (linke) Grassroots-Gruppen - wer entscheidet, wem wann wie geholfen wird...und wo verkommt humanitäre Praxis zum politischen Spielfeld Aus Kritik am humanitären System der UN und seinen beteiligten Groß-NGOs haben sich viele (linke) Grassroots-Gruppen gegründet. Auch diese können natürlich nicht ohne finanzielle Mittel arbeiten, und sind somit auf Spenden, ergo auf Öffentlichkeitsarbeit angewiesen. Wie entscheiden die "Großen" wann und wie und wem geholfen wird? Welche Lücken bleiben dabei (zwangsläufig)? Und wie werden diese Entscheidungen bei den Grassroots getroffen? Und welche Auswirkungen auf die Wahrnehmung von Krisen hat ihre Öffentlichkeitsarbeit? "Trommeln gehört zum Handwerk", aber wo läuft linkes humanitäres Engagement Gefahr, in rein politisch motivierten Aktivismus abzudriften? Und wenn das schlimm ist, warum? Eine kritische Betrachtungsweise. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/BBGXPY/

Gluon mit BATMAN setzt klassisch auf ein großes Layer 2 Netz, was in den großen Freifunk Communities zu Problemen führt. Mit unseren Bemühungen in "Project Parker" versuchen wir diese Probleme durch den Einsatz von klassischem Routing zu umgehen. In unserem Talk stellen wir unsere Architektur vor und zeigen welchen Stand unsere Umsetzung erreicht hat. Gluon mit BATMAN setzt klassisch auf ein großes Layer 2 Netz, was in den großen Freifunk Communities zu Problemen führt. Diese Communities begegnen den Problemen i.d.R. mit der Segmentierung des Netzes in Domains. Innerhalb dieser Domains wird allerdings das klassische Netz (BATMAN) eingesetzt. Mit "Project Parker" versuchen wir diese Probleme durch klassisches Routing in einem hierarchischem Netz zu lösen: Jeder Freifunk-Knoten mit Uplink ist Gateway für sein Netzsegment, macht DHCP und ist DNS-Cache. Das Routing mit BATMAN beschränkt sich nun auf kleine Mesh-Netze innerhalb des gesamten Netzes. Wir stellen in unserem Talk unsere Architektur vor und zeigen welchen Stand unsere Umsetzung erreicht hat. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/V3XY87/

Careables Calling all hackers, designers, makers, carers, and healthcare professionals! What are challenges you face every day using standard tools for health and wellbeing? Do you have an idea that makes everyday life easier? How could you use your existing hackerspace to foster exchange and collaboration in health and care? Through Careables, maker and designer collaborate with patients and healthcare professionals to create personalized solutions and open source knowledge that will improve the lives of many patients and professionals. Accessible, comprehensive and easy to use open source hardware are being documented, collected and shared through the platform Careables.org. This platform is currently being launched and will function as repository for well documented open hardware projects. It offers many different communities a place to connect and exchange knowledge, needs and co-create solutions. It's easy to think of open hardware that make a difference in people's lives. An example of this is OPEN LIGHTS. This project offers people with wheelchairs an adjustable wheelchair specific light that makes them better visible at night and that can be built with most common DIY technologies. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/SWS3WR/

envisioning a thriving, connected future amidst conflict-struck Nigeria. Creating opportunities for rural women and youth, in a scalable, inclusive way. ###About the presenter Paul Henckel from TribeGroup (DK-based) will share his thoughts and plans for an ongoing resilience project with Fantsuam (NG-based) in creating ICT coworking spaces for rural women and youths in Nigeria, using the knowledge from Freifunk communities. ###About TribeGroup TribeGroup is a Danish impact investment startup with mission to support or invest in other companies, projects or initiatives that have a potentially high social or environmental impact. It currently directs WorkHive, a flexible, affordable, inclusive and carbon negative coworking space in Copenhagen. The collaboration with Nigerian-based Fantsuam tries to integrate best practices of Freifunk, Fantsuam and WorkHive to create a new coworking space in Kafanchan, Nigeria. ###About Fantsuam Our Mission at Fantsuam Foundation (www.fantsuam.org) is to eliminate poverty and disadvantage among rural women and youths in Nigeria through integrated development programs. At our ICT Academy,In 22 years, we have empowered 12,000, and we aim to educate women and youths with relevant digital literacy skills to manage their development priorities, providing opportunities for girls to become developers and deploy ICT solutions for their livelihoods. Our services have become even more imperative as our communities come out of decade long cycles of sectarian violence. We plan to reach 25,000 more by 2020. Community Network, is a resilient communication platform in which the community owns, manages and maintains its own communication infrastructure provides the opportunities for rural youths to gain the necessary hands-on experience. Fantsuam Foundation hosts the Google Developers Group in Kafanchan, this is another resource that is being deployed to provide ICT skills and knowledge opportunities for our youths. We are now engaged in high level policy advocacy for affordable and available internet access for the unconnected in rural Nigeria. Obtaining the TVWS concession for the unconnected in Nigeria will begin to make for an inclusive national telecommunication effort. It is within that context that Fantsuam continues to support the increasing number of youths, particularly females, who now recognise the career opportunities available in ICT. Our ICT Academy provides basic digital literacy training and has expanded to provision of training in computer and network maintenance. In order to optimise the use of resources and make our services more accessible, we have located an office space in the Kafanchan Railway town where we would like to set up an ICT Co-Working space where budding entrepreneurs can have ready access to training and mentoring facilities, office space with assured power and internet access at affordable prices. Our efforts at tackling poverty through an integrated approach has meant that we also provide social services in public health, menstrual health hygiene, sanitation marketing, peace building, entrepreneurship training supported by microfinance. We currently have 32 full time staff and a large pool of volunteers who are invited to join specific projects and programs, which are usually of short duration. Our work in peace building led us to build six new apartments for victims of recent sectarian crisis, and we continue to explore opportunities to enable our communities to resume their normal lives. Our model of farming cooperatives, called the TIME-AID, empowers individuals and families to engage in commercial farming with the goal of household food security, family health insurance, adequate housing and education for all our children. Fantsuam Foundation’s integrated approach to develop has enabled it to have an inbuilt resilience to cope with the challenges of rural development, global economic challenges whose effects are usually more devastating at the base of the pyramid, while we continue to develop initiatives that helps the people to assert their humanity and freedom from poverty. about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/7BRU3D/

The Prototype Fund is a funding program for Public Interest Techfirst of its kind in Germany and supports independent software developers, hackers and creative people in implementing their open source ideas from concept to first demo. Since 2016, we (Adriana, Elisa, Fiona, Julia and Katharina) have been working to break down existing structures and narratives in the field of innovation funding and to encourage meaningful digital solutions for society in Software Infrastructure, IT-Security, Data Literacy and Civic Tech. We want to get to know you and your ideas and talk about how we, together with politicians, developers and other initiators from the (active) civil society, can best support, develop and make visible good digital-social innovation practices from the perspective of the community. Which decisions are necessary in the future, what are meaningful political demands? And which are the next big things in Tech? Get to know us, ask us everything, recover from the hustle and bustle of the congress! about this event: https://pretalx.35c3oio.freifunk.space/35c3oio/talk/V8RTSW/
