Even more than elsewhere, the best map of Kosovo can only come from local mappers - big proprietary map makers can't and don't care to keep up. This is how the Kosovo community managed to get official data opened, how we integrated that data into the map, and how people in Kosovo are using the map.

In XMPP there is a over 14 years of experience with end to end encryption in distributed chat systems. After 4 standards for e2e encryption, we are still not content. So what makes it so hard to come up with a good encryption standard? Well, to name some of the issues: - what is the threat model e2e encryption should protect against? - what about the metadata? - what about audit trails? - what about archives? - what about group chats? - what about multiple devices? - what about key-verification? After this talk you will never look at e2e encrypted chats in the same way again. In XMPP there is a over 14 years of experience with end to end encryption in distributed chat systems.

I shall explain the renewed interest in mix networks. Like Tor, mix networks protect against metadata leakage by using layered encryption and routing packets between a series of independent nodes. Mix networks resist vastly more powerful adversary models than Tor though, including global passive adversaries. In so doing, mix networks add both latency and cover traffic. We shall outline the basic components of a mix network, touch on their roles in resisting active and passive attacks, and discuss how the latency impacts reliability, application design, and user experience.

A password shouldn't be on a post-it note. In plain view. On the console. The password to a locked door is called a key. So if a reporter wants to get the point across that certain people shouldn't have access to a particular key, would it be wise for said reporter to show that key to the world? This talk will show how not to run this story, why we should care and maybe make you rethink your physical security a bit. A password shouldn't be on a post-it note. In plain view. On the console.

Deploying software has lots of solutions, but what gets deployed often plays out as a fight between developers and operators. Developers want the latest (or at least later) code. Operators want things in nice packages, certified, and with a known period of support. What we need is a catalog of software with the variety of versions the developers need, with the qualities expected by the operators. Come and learn how various projects within Fedora approach this problem from different perspectives, including Fedora Modularity, containers, Fedora CoreOS, and Fedora Silverblue.

Giving your software away for free is a terrible way to make money. But entrepreneurs should still consider open sourcing their software--many successful companies have done so! But how? The goal of the podcast "Open Source Underdogs" was to interview the most prominent founders in the industry to shed light on their stories. Although each business is different, some common themes emerge. In this talk, Mike will talk about what he's learned after the last 22 interviews. The goal is to both inspire and challenge entreneurs to consider open source software developement's strengths and weaknesses as part of a business model. Information on this topic will be gathered from descriptive data of the social networks,from media and from direct answers on how much time people (students, random workers) spend.

In 1974 Fred Brooks argued that an app requires nine times extra work to take it from merely being functional, to being a usable product. This challenge is as real now as it was then. What is this extra work, and can you do it using pure Open Source?

During 2018 I've been a contractor for the Italian Digital Transformation Team working on docs.italia.it (Docs Italia), a platform to collect and share the Public Administration documentation. Docs Italia is an Open Source platform based on the Read The Docs code. Working in the open posed its own set of issues: - does contributing upstream deliver value to our project? - working productively with an Open Source community - managing an Open Source project fork In this talk I'll share what we did and how it did go.

Why is software that is programmed with taxpayers' money not released as Free Software? We want legislation requiring that publicly financed software developed for public sector must be made publicly available under a Free and Open Source Software licence. If it is public money, it should be public code as well. Code paid by all people should be available to all people! This talk will provide a brief overview of the FSFE's previous and ongoing activities to foster software freedom in Europe on the levels of politics, legal work with enterprises, and general public awareness.

"Shoot ALL the Hackers!": one of the long-running photography projects by Dennis van Zuijlekom (Hackerspace Hack42, Arnhem). Its focus is portrait photography of persons who relate themselves to hacker/maker culture. Dennis started this project in 2015 and it'll never be truly finished, as there will always be new hackers to photograph, as well as old friends having new faces. Dennis takes great pride in photographing people looking at their very best and the results speak for themselves. He'll invite you to have your headshot taken during this event (and/or sometime afterwards). You'll be using his photo in your personal bio, guaranteed. The project and the photos are licensed Creative Commons, CC-BY-SA, as Open Source and free/libre content is important to Dennis.
