Running Android on the Mainline Graphics Stack

Privatization, gentrification and displacement have become common urban topics – affordable housing is an increasingly scarce resource. A large number of experts from different fields are working on this topic – today, we’d like to present an intersection between urban planning, architecture, open source software and 3-D printing which seems to present an alternative to the standard privatized housing market. Mary Dellenbaugh-Losse is a landscape architect and urban geographer working on affordable housing and urban commons. [Read More]

Copying WhatsApp the right way

In den fünf Jahren seines Bestehens setzt der Android Jabber/XMPP client immer wieder Maßstäbe in Sachen Bedienbarkeit und Zuverlässigkeit. Doch was steckt eigentlich dahinter? Nutzen wir die Gelegenheit um mit dem Entwickler zusammen hinter die Kulissen eines neuen Features zu schauen; Wie tief muss man in die XMPP Trickkiste greifen und wo steht sich XMPP manchmal selber im Weg? Nach der Vorstellung des Features (der Vortrag ist gleichzeitig der Zeitpunkt an dem die neue Version veröffentlicht wird) geht es jedoch nicht nur um XMPP sondern auch um grundsätzliche, architektonische Fragen die sich potentiell auf andere Instant Messaging Dienste übertragen lassen.

Lightning Talks

What? Lightning talks are 10 minute talks about anything. Well, anything that won’t make other people want to throw you out. Apart from that it can be anything: An idea you have, a problem you cannot solve, your favourite tool, or just about anything you think everybody else should have heard about (i.e. the awesome talk you will be giving soon)! It’s really up to you!

Talks:

  • Peter: Gentoo catalyst instead of $distro+Ansible
  • Matthias: Looking next door through Alice - Your friendly BGP looking glass
  • Hanno: MIME-Types, Apache and XSS
  • Starbug: Passworte abhören

Programming Languages and Trust

The what, why, and how (and the hacks) Compilers and interpreters are the foundation of programming languages, the first tier in software abstraction. They come in all sizes, shapes, and colors, and they power all kinds of programming languages. For many of us they are black boxes. In the first section of this talk we’ll try to look into the box: how do compilers and interpreters actually work? After a bit of foundational information, we’ll look at a silly, simple virtual machine and JIT compiler built by yours truly. [Read More]

deSEC: Sicheres DNS-Hosting für alle

deSEC ist ein quelloffener und datenschutzfreundlicher DNS-Hosting-Dienst aus Berlin. Ursprünglich aus einem Start-up-Stipendium finanziert möchte deSEC DNS-Hosting nun dauerhaft kostenlos auf Basis von Sponsoren anbieten. Dabei bietet deSEC Funktionen an, die bei anderen Dienstleistern bisher nur selten gesehen werden, insbesondere eine Restful API, automatisches DNSSEC, volle IPv6-Funktionalität sowie schnelle Aktualisierung der DNS-Informationen auf den authoritativen Servern. Im Vortrag wird die technische Organisation der deSEC-Dienste diskutiert sowie die Sicherheit und Privatheit des Dienstes, insbesondere im Kontext von Missbrauch und Hochverfügbarkeit dargestellt.

MNT Reform -- Der neue offene Computer durchleuchtet

MNT Reform ist ein neuer tragbarer Computer, der modular aufgebaut und von seinen NutzerInnen modifiziert/repariert/gehackt werden soll. Ziel ist es u.a., das gesamte System zu dokumentieren und Teile per 3D-Druck, CNC usw. austauschbar zu machen. Dabei sind alle von uns (Lukas F. Hartmann und Ana Dantas) entwickelten elektronischen und mechanischen Bestandteile GPLv3-lizensiert. Ich werde eine aktuelle Version des Laptops mitbringen und das System im Vortrag beschreiben, sowie Hürden, Schwierigkeiten und Zukunftspläne erklären. [Read More]

Open Source Housing? 3D printing, open source, tiny houses & the commons

Privatization, gentrification and displacement have become common urban topics – affordable housing is an increasingly scarce resource.

(In)Security in Software-Defined Networks

Computer networking is currently undergoing a transformation: Network control is being consolidated into a centralized “controller” by separating the so-called data plane and control plane. This transformation is what is popularly known as Software-Defined Networking. In this talk we will see how Software-Defined Networks can be exploited by attackers, and on the flip-side, how they can be leveraged to detect network attacks. For example, we will look at topology spoofing attacks, software switch exploitation in the cloud and attacks arising from malicious switches, we will also see novel techniques to detect malicious switches and hosts.

Progress in the Embedded GPU space

Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have Open Source support and for those that aren’t supported yet, improvements are happening at a rapid pace. In just the last year Vivante GPUs have gained mainline support and Mali GPUs have seen good progress being made. In this talk, Robert will cover GPUs in the embedded space and give an overview about their current status, what lies ahead and how the Open Source state of the art compares to the proprietary alternatives.
