opsi ist ein heterogenes OpenSource Client-Management-System. Dieser Vortrag gibt einen Einblick in die Testinfrastruktur, die mit den Jahren aufgebaut wurde, um die Entwicklung und die Releases vom opsi-Projekt zu unterstützen. Das reicht von Codetests bis zu End-To-End-Tests. Dabei wird ein Einblick gegeben, welche Technologien eingesetzt werden und wie die Test-Strategie umgesetzt wurde. CI First hat sich als goldene Regel etabliert. Aber was bedeutet das und vor allem warum ist das wichtig? Auch diese Fragen werden im Vortrag beantwortet.

The Amazon Forest, its traditional peoples, and riverside communities represent an immense challenge for official cartography, due to scale and extension factors. This presentation aims to show the experiences of the Unificar Ações e Informações Geoespaciais (UAIGeo) chapter of the Brazilian YouthMappers in mapping riverside communities in the Amazon rainforest region, focusing on the city of Tefé and its islands. Due to its female leadership role and the goals of empowering young women in geospatial and technical skills, the presentation emphasizes the importance of engaging and encouraging female students to link mapping and female empowerment.

In Brazil, it is still an immense challenge to produce official cartography on the regional and local scale due to the extension of the territory, the number of municipalities (5,568 plus the Federal District), and the expensive cost of producing the mapping. Such factors are more significant in the Northern Region of the Country, where an important part of the Brazilian Amazon Forest and many traditional peoples and riverside communities are located. Many of the riverside communities do not have records in documents about their ancestral knowledge, cultures, territories, etc. Their knowledge and stories are transmitted orally and, despite the importance of this legitimate source of data, an important amount of information can be lost over time [1] The distances between riverside communities, in addition to the small geographic space the built infrastructure occupies, make them invisible in many official mapping. The riverside buildings are not visible in official mappings and have cultivated areas between 0,2 to 3 hectares. In this context, collaborative mapping through open data platforms is one cheaper possibility to mitigate the lack of maps in Brazilian municipalities. The OpenStreetMap (OSM) platform emerges as promising because it has wide territorial coverage of high-resolution images, which makes it possible to view the communities on the local cartographic scale.

This presentation has the aim to show the experiences of the Brazilian YouthMappers’ chapter Unificar Ações e Informações Geoespaciais (UAIGeo), in partner with Centro de Estudos Superiores de Tefé-Universidade do Estado do Amazonas - CEST/UEA, within mapping riverside communities in the Amazon rainforest. In its initial phase, the project received support from the Everywhere She Maps program, due to its women leadership role and goals of empowering young women in geospatial and technical skills. Globally, on average 35% of female students entering the university choose fields in science, technology, engineering, and math - STEM [2]. The Global Gender Gap Report 2020 shows that Brazilian women represent just 18% of employees in technological jobs, a percentage below the global average [3]. Additionally, according to a study that has analyzed OSM users and the manifested gender, by 2019 female participation reached 13% [4]. For this reason, this presentation emphasizes how important it is to engage and incentivize women’s participation both from external and local communities. Gender relations are important components of key forest-related issues, such as climate change and the differences in opportunities facing women in these contexts. However, there is little literature on forest and gender in Latin America, particularly in the Amazon Forest [5] The chapter have been coordinating a series of mapping activities focused on the municipality of Tefé and verified that volunteers have mapped so far 11.082 buildings in the Humanitarian OpenStreetMap Tasking Manager platform since last year. Together with local collaborators from CEST/UEA, chapter members validated some names of communities on one of Tefé’s islands. Chapter members carried out fieldwork in Tefé to know the local reality and some places that they had mapped. They also conducted studies in São Luís do Macari, a community that is located on an island in the middle of the Solimões River. Results of remote and fieldwork activities will be presented while at the same time emphasizing the importance of engaging and encouraging female students to link mapping and female empowerment.

OpenStreetMap Foundation Board Ask Us Anything (i.e. AMA). We will take questions from the audience, or other questions that people can submit before the event, and we will talk about and answer them. We can talk about the past actions of the board, and what future plans we have.

This is a chance to ask the OSM Foundation Board questions, to engage with the board. Let’s have a conversation about the Foundation, the Board and how all the parts work together. If you know nothing about what the board is doing, this is a chance to find out. Find out what the Foundation does and doesn’t do, what it can and can’t do. Find out how you can help, how you can get involved. The Board is committed to openness and wants to engage with the community.

OSM is almost 20 years old and we already achieved so much. What if the governance of the project as well as our relationship to time and money were the biggest obstacles to ensure a bright future?

Let’s discuss the priorities to unleash the full potential of our community.

Our digital champions project in Tanzania has transformed the lives of 353 women who had never used a smartphone before into confident advocates of mapping in their extremely marginalised communities. They have delivered training to over 9000 women in these villages and reported over 470 cases of gender based violence in their villages to the police and social services who have then used the maps to find and protect these women. Giving local women and youth the digital tools to protect their sisters in their communities is an extremely cost effective, long term solution to build up our mapping community and make it more inclusive, and share lessons learnt

The Ahrtal flood disaster and a war in Europe will obviously increase requirements on geo-redundancy. OpenSource via MARS can help.

Experiences from 1&1 IONOS datacenters running millions of customers and petabytes of data will inform you on current state and on future trends.

This talk will discuss more possibilties for datacenters, how geo-redundancy can be built and operated, and in long term.

The Linux kernel module MARS is now replicating more than 10 petabytes over long distances, running on thousands of servers. A future version shall be able to replace iSCSI inside of any geo-redundant datacenter, providing location transparency of /dev/mars/mydata by local handover while the virtual device can stay mounted, in addition to geo-redundant long-distance handover and failover.

Pull requests sind ein Weg, den Software-Entwicklungsprozess zu organiseren und robuster zu gestalten. Sie sind besonders nützlich bei lokal und zeitlich verteilter Zusammenarbeit, in globalen Open Source-Projekten wie auch in kleineren Unternehmen.

Aber was macht gute Pull Requests aus? Gutes Reviews? Und wie können wir den Weg für beide ebnen?

Malte erzählt, was er von Open Source-Projekten zum Umgang mit Pull Requests gelernt hat, welche Synergien sich in seinem Entwicklungsprozess ergeben haben und gibt ein paar weitere Ideen zur Einrichtung der Umgebung, zum Schreiben, zum Reviewen und zum Mergen von Pull Requests.

Kann es nicht vorteilhaft sein sich mit anderen Open Source Projekten oder sogar mit Unternehmen zu vernetzen und sich auszutauschen? Das wird jetzt zwischen Linux-Distributionen und IBM beim Open Mainframe Project praktiziert. Daneben gibt es viele weitere Möglichkeiten sich auch als Unternehmen in Open Source Projekten einzubringen. Das wird hier im Vortrag mit integriert.

Open-Source-Projekte – besonders Linux-Distributionen – zeichnen sich durch die Zusammenarbeit in Upstream-Projekten aus. Auch für Unternehmen kann es von Vorteil sein, zu Open-Source-Projekten beizutragen. Man baut seine Partnerschaften aus, arbeitet über Communities mit anderen Unternehmen zusammen und kann so auch etwas für die Kunden tun.

Aber ist es auch möglich, dass mehrere Linux-Distributionen sich für die Zusammenarbeit mit Unternehmen in Arbeitsgruppen organisieren? Das wurde von openSUSE, Fedora und Debian für eine bessere Zusammenarbeit mit IBM über das Open Mainframe Project als Beispiel organisiert. In diesem Vortrag geht es um die Vorteile für Unternehmen zur Zusammenarbeit mit Open Source Communities wie auch die Möglichkeiten und Vorteile der Zusammenarbeit zwischen Open-Source-Projekten.

Der Vortrag erklär anhand von Beispielen aus den Berichten der Beauftragten für den Datenschutz, welche Fehler bei der Programmierung und Anwendung von Software gemacht und durch die Datenschutzbehörden beanstandet wurden.

Im Anwendungabereich der Datenschutzgrundverordnung sind durch die Verantwortlichen die datenschutzrechtlichen Grundsätze einzuhalten. Der Vortrag erklärt, warum es die datenschutzrechtlichen Grundsätze gibt und zeigt exemplarisch anhand von Beispielen aus den Datenschutzberichten der (Landes-) Beauftragten für den Datenschutz (und die Infromationsfreiheit) welche Fehler bei der Programmierung und Anwendung von Software gemacht und durch die Datenschutzbehörden beanstandet wurden. Die Nichtberücksichtigung der datenschutzrechtlichen Vorgaben stellt für den Softwareentwickler unter Umständen auch ein rechtliches Risiko trotz weitestgehendem Haftungsausschluss durch FOSS-Lizenzen dar. Wann dies der Fall ist, wird abschließend kurz erläutert.

Smartphones and other mobile devices are ubiquitous and while we're picky about free software on our laptops, desktops and servers lots of us have a truck load full of proprietary software in their pocket every day. Does it have to be that way?

How would a way out of the duopoly look like? What are the upsides? What works today? What are the gaps? How can you get involved?
