The initial idea of our project started after a dedicated research project developed on the urban texture of the city of Tirana where many issues of the urban development were identified. This lead to the grassroots development of Preservingtirana.city as a necessary, interactive platform for the online documentation of some important assets of Tirana's Identity as a city, the 'neglected buildings...

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 abo...

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 c...

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 physi...

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....

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...

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...

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 br...

"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 p...

Das OpenStreetMap-Projekt ist die größte Datenbank an frei verwendbaren Geoinformationen. Das Projekt erlaubte bisher über einer Millionen Menschen gemeinsam eine weltweite digitale Karte zu erstellen. Damit können auch besonders verwundbare Orte kartographiert und die Daten von Hilfsorganisationen und staatlichen Hilfswerken verwendet werden. Felix arbeitet für das Human...

Because we couldn't find any decent multi-slot SIM card (e.g. smart card) reader, we decided to build our own: the sysmoOCTSIM. This use the recent Microchip SAM E54 micro-controller, which is only supported by the Atmel START web-based IDE. We will briefly present the sysmoOCTSIM and how to get started with Atmel START. about this event: https://pretalx.sysmocom.de/osmodevcon2019/talk/C8XLTD

This is half presentation, half discussion. I don't think I have all the relevant answers, but it's pretty clear where the TODO areas are: * combined HLR+HSS with GSUP for Osmocom and DIAMETER for LTE * com...

In this talk we will present the system we used in the HERMES (High-frequency Emergency and Rural Multimedia Exchange System), winner of the Off-the-Grid Internet Challenge of Mozilla WINS Challenge. At HERMES demonstration in Mexico the system was composed by a couple of ICOM IC-7100 radios (100W peak output power), doing NVIS (Near Vertical Incidence Skywave) skywave communication between a comm...

I would like to share my progress in porting layer1 to fernvale (MediaTek 626x chipset) and discuss how best to proceed with the goal of getting layer1+nuttx+mobile on fernvale as well as related devices like sim800[A-Z] and dz-09 like watches. Possibly also discussing newer chipsets like mtk6735/6737 (zte obsidian and orange pi 4g/iot board). about this event: https://pretalx.sysmocom.de/osmodevc...
