A generation ago, "cyberspace" was just a term from science fiction. Today, our entire modern way of life, from communication to commerce to conflict, fundamentally depends on the Internet. And the security issues that result challenge literally everyone: politicians wrestling with everything from cybercrime to online freedom; generals protecting the nation from new forms of attack, while planning new cyberwars; executives defending firms from once unimaginable threats, and looking to make money off of them; journalists reporting new stories, and using new tools to do so. Most of all, cybersecurity issues challenge us as individuals. We face new questions in everything from our rights and responsibilities as citizens of both the online and real world to simply how to protect ourselves and our families from a new type of danger. And, yet there is perhaps no issue that has grown so important, so quickly, and touches so many, that remains so poorly understood.

We develop an open smart home platform

• connecting the open internet, intelligent appliances and new smart services

• make them available across all screens, independent of operating systems

• with just one piece of hardware

• opensource, open API, highly secure

• to help the household community discover a new world at home

To do so, we have defined a reference stack for a smart home gateway based on eclipse smart home where all smart devices and appliances can be connected through bindings and drivers, build up a cloud infrastructure to connect web developers that can develop HTML5 based applications for the smart home and developed an adaptive frontend for the end-user. We will show a live demo of the system working end to end in the presentation.

The "eternal" laws of ICT fall. ICT solutions in our daily lives occur in interactions with the business IT. They change our perception and action fields, create new opportunities, but also call for new behavior. Whether in the realm of automotive, energy, finance, health or life and living - the list of possibilities with ICT outside of standard office applications from day to day becomes longer, more exciting, more challenging. The journey to the future has begun.

Tor is free software and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Torservers.net operates many of these Tor relays. It started as a German non-profit in 2010, and spun off many similar organizations over the past years. Torservers.net now consists of 13 partner organizations in 10 countries, many of which were created solely to run Tor relays on a volunteer basis. We collaborate with Human Rights organizations such as the Institute for War & Peace reporting and Reporters Without Borders, teach about Tor & online security, and connect users and journalists with professionals.

This is the story of Torservers.net, presented by its founder, Moritz Bartl.

We explore how the recent string of giga-acquisitions and mega-financing rounds for private companies in the technology space are impacting the global landscape of technology company development and the venture capital ecosystem. Is the M&A machinery of Google, Facebook, Amazon and Apple “a good thing” – and for whom? Where is Europe in this game? Or even – Germany? Is hardware company formation still feasible - or has software already “eaten the world”? We will explore a couple of exciting questions, but will probably fall short of providing many conclusive answers.

Cache-oblivious algorithms let us perform optimally for all cache levels in your system at the same time by optimizing for one cache for which we don't know the parameters. How can we derive new functional data structures from these techniques? We'll need to take a detour through deriving data structures from number systems to convert a dynamization technique from 1980 into something suitable for functional programming and concoct a notion of safe idempotent effects in pursuit of both practical and asymptotic performance gains.

Java 8 is the biggest release since 10 years and will fundamentally change how to program in Java. With the introduction of Lambdas, Java programmer now also get the possibility of writing concise functional code without having to use anonymous classes. Crucial, however, is the fact that besides the language, the standard library of Java has been optimized for lambdas. Especially the completely new Stream classes release the full power of lambdas.

The Lua programming language has been around for over 20 years. Originally invented as a data description and configuration language at the Pontifical Catholic University of Rio de Janeiro in 1993, Lua is nowadays employed for manyfold purposes in a broad range of applications. For example, Lua has gained traction in the video game development industry where it is used as a scripting language, attributed to the fact that it is cross-platform and easy to embed, its fast execution speed, and a moderate learning curve. Lua can be described as a designed lightweight and flexible multi-paradigm programming language with extensible semantics. The latter is manifested, for instance, in the intentional lack of a language built-in standard object model. Instead, the means to implement most of the traditional object-oriented programming concepts and styles commonly found in other languages are provided. Likewise, a set of advanced features such as first-class functions allowing the employment of powerful techniques from functional programming, garbage collection, closures, proper tail calls, coercion, cooperative multitasking in terms of coroutines, and dynamic module loading is available. In general, Lua implements a distinctive balance between power and size, rendering it a noteworthy programming language. This talk aims at giving an introduction to the Lua programming language, highlighting some of its particular features.

In the last few decades the computing power of a single chip has increased exponentially as predicted by Moore’s law. However, there are still interesting problems which cannot be solved in an adequate time as they become larger on a classical computer. Therefore, the idea of building computers based on the fundamental principles of quantum mechanics was proposed with the hope that harnessing quantum effects might lead to an exponential speed-up in solving some of these hard problems. Until now, there has been a tremendous progress in the development of non-trivial quantum devices. While a universal quantum computer of non-trivial size is still out of reach, a number of experimental and commercial devices based on quantum effects already exist: quantum random number generators, quantum encryption systems, and quantum annealers. Recently the Canadian company D-Wave Systems is selling a special purpose device for solving optimization problems which is based on the idea of quantum annealing. In this talk I will give an introduction to classical and quantum annealing which can be used to solve optimization problems. Then, I will present and discuss the benchmark results of the D-Wave device.

Thunder and lightning trigger fear and anxiety in many people. Among the technically interested weather freaks though, they often awaken a spirit of research. Each lightning bolt sends an electromagnetic pulse. To determine the impact locations of the flashes, we developed high-precision detectors to allow to measure the time of a lightning pulse with microsecond precision. The Blitzortung.org community consists of individuals, who installed their own self-built station for locating lightning at their home or in their garden. They live in Europe , the U.S., Oceania and soon in South America as well. The stations send their data via Internet to a central server, which must receive and process millions of signals per hour at peak times. We explain in this talk, how the project "Blitzortung.org" works and why it fascinates such a huge number of participants so long-lasting.

This talk deals with the fundamental questions in theoretical computer science. Before the advent of modern computers it was David Hilbert (in 1928) who asked ‘for an algorithm to decide whether a given statement is provable from the axioms using the rules of logic'. Church and Turing proved in 1936 that none exists! This was the beginning of Turing machines; paving the way for real computers. After decades of mathematical and physical progress, we now do not worry so much about the uncomputable problems but the ones that are *hard* for the machines, in the sense of time-complexity. Real life examples are combinatorial problems (eg. counting graph matchings) or number theory problems (eg. integer factoring). We will discuss the history of computation, and some conjectures about these hard problems which mark the current frontier of our understanding.

Whereas watching 3D-movies or even 4D-movies in our leisure time rapidly gains popularity, researchers are currently thrilled to dive into the recently discovered two-dimensional world where they can explore extremely thin crystals that consist of only a single sheet of atoms. Initially, the protagonist in this 2D world has been graphene. It is composed solely of carbon atoms, which are arranged in a hexagonal honeycomb pattern. Describing graphene’s properties requires the use of superlatives. It beats copper when it comes to electrical conduction and leaves iron far behind where mechanical strength is concerned. This 2D-world is fast-paced and graphene has been joined by other two-dimensional crystals with distinct properties. By now there is something close to the heart of every physicist. We are learning how to handle these 2D crystals and how to place them with high precision at an arbitrary location. These capabilities are the prerequisites to build hybrid stacks of these crystals in order to generate materials with novel functionalities. Currently these activities resemble playing lego for adult researchers, however the scenario stipulates that all of this should turn into a powerful materials design platform for engineers. This presentation will be a taster of this 2D world which, many believe, has a bright future.

Existing markets are rapidly changing, the pressure on established companies to innovate has been increasing, particularly through digitization. Thus, companies that are too narrowly focused on existing core products, are forced onto the defensive. In part, corporations act and react slowly, with potentially fatal consequences. We show strategies, tools and examples that increase the chances not to lose markets and customers out of sight. Data-proven hypotheses and evidence-based decisions can help to evaluate new business models quickly and inexpensively. Simple experiments allow to develop only the features that are proven to have a benefit for customers.

The Volocopter of e-volo is an aviation revolution made in Germany (e-volo). Safer, easier and cleaner than ordinary helicopters, it changes the nature of locomotion. The Volocopter is an environmentally friendly and emission-free private helicopter with electric drive. In contrast to every other aircraft, the handling of the Volocopters is child’s play. In addition to the delightfully simple construction without complicated mechanics, the redundancy of the drives is another major advantage. The automatic position control and directional control (fly-by-joystick) takes place with several independent and mutually monitoring onboard computers that control each electric motor separately in its speed. If the electronics and software also plays for the first time in private flights a crucial role. In this talk, the development from the idea to the real Volocopter VC200 is shown. After extensive stress testing a provisional airworthiness certification is to be achieved in 2014 and manned test flights are to come up as well. As part of the newly created class of ultralight rotor flyers called Volocopter, a type certification of the VC200 for the future planned series production will be made possible. You will therefore soon be able to fly the Volocopters of e-volo in Germany with a sport pilot license.

The Festo Bionic Learning Network is a collaboration between Festo and universities, institutes and development companies. Within this initiative, nature creates new perspectives and gives new impetus to industrial applications and possible future series products. Automated movements can be made more productive and energy-efficient by following natural principles.

Autonomous driving has for many years and decades been a dream that would allow people new individual freedom of movement and even completely new mobility concepts. 125 years after the first automotive overland trip through Bertha Benz, we have navigated the historic route from Mannheim to Pforzheim autonomously. What technological challenges had to be overcome here, what technological and social challenges will still to be faced up to an introduction into series vehicles yet and what autonomous systems we will soon be able to see on our roads, is illuminated in this talk.

Migrating complex systems usually will consume time and money, and carry huge and incalculable risks. The problem is that often it is not possible to migrate only one system due to intricate dependencies with other systems. In some cases this is a reason to delay or even cancel a necessary migration. Having seen our clients facing this problem, we devised a new approach to decouple migrations. Instead of migrating all coupled systems at the same time, also known as the Big Bang approach, we decouple the systems and migrate them one by one. This will reduce risk and complexity. The decoupling will also allow to handle delays and requirement changes in an agile manner. This talk will present our approach and how it holds up in practice.

Self-organizing agile teams have fun at work, play cards together regularly, developers sit on a Computer in pairs and a lot of test code is written that is not even needed for the solution of the actual problem, and all this should be better than the decades-proven classic software development methods?!? Often proponents of agile methods are therefore confronted with appropriate scepticism or outright rejection. This presentation will address frequent criticisms and based on results of studies, experience reports, and personal experience will provide arguments at hand, why agile methods actually "pay" for the donors in the end.

The organization of a multi-customer software engineering project course with real customers from industry is a challenge for instructors. Traditionally, many instructors prefer projects with simple problem statements and friendly customers recruited from the neighbor office to minimize the effort when teaching the course. However, toy projects do not motivate students: their learning experience is generally low and they become easily bored when creative aspects are not included. To address the creative aspects of software development we incorporate informal modeling, movie trailers and executable prototypes. To make sure that multiple increments of the systems are delivered to the customer, we use agile methods and continuous delivery. Agile methods have become mainstream in industry, but many instructors are still struggling to incorporate them into their curriculum. In this talk I present the management issues for a single-semester software engineering project course with real customers. I discuss some of the key concepts that make the course successful and exciting for students, instructors, and the participating industry partners using examples from more than 50 projects with 30 different industry partners.

Building on the success of Reactive Extensions — first in Rx.NET and now in RxJava — we are taking Observers and Observables to the next level: by adding the capability of handling back-pressure between asynchronous execution stages we enable the distribution of stream processing across a cluster of potentially thousands of nodes. The project defines the common interfaces for interoperable stream implementations on the JVM and is the result of a collaboration between Twitter, Netflix, Pivotal, RedHat and Typesafe. In this presentation I introduce the guiding principles behind its design and show examples using the actor-based implementation in Akka.

Trends in social media, location sensing, wearable devices, and industrial internet push the need for dealing efficiently with Big Data in motion. Complex Event Processing (CEP) is an innovative technology to analyze high-volume, low-latency data streams on-the-fly. In contrast to traditional approaches, it does not require storing data prior to analysis. CEP provides continuous streaming analytics to detect patterns and derive meaningful business events from different event streams or other event sources like databases or in-memory caches in real-time to gain situation awareness and trigger immediate actions. This allows organizations to correlate and analyze business activities across multiple data streams in real-time and take the next best action to improve business outcomes. This presentation will provide an introduction to CEP, give examples for developing stream processing applications using the Apama CEP platform, and outline the larger streaming analytics solution of Software AG by giving examples from real-world use cases.

Software today increasingly stands for distributed, interconnected systems. SOA, Hadoop clusters, or software stacks integrated via REST: all of these architectures make it difficult for developers to test their software. Setting up local or continuous integration environments for end-to-end or acceptance testing is a pain. Docker is a virtualization solution based on Linux Containers (LXC). It enables developers to rapidly start preconfigured containers, complete with operating system and installed packages - without the overhead of "real" virtualization. Using Docker, whole environments can be created and wired together in seconds. This talk demonstrates how Docker can make life easier for developers, and even be the first step towards continuous delivery.

The programming of CNC driven machine tools, the backbone of industrial production of complex components, is still based on a '50s programming language. Numerous language dialects, vendor-specific quirks, intermediate languages such as APT- code post-processors, etc. have created a confused variety of industrial software in order to get from the idea – the 3D-CAD model – via CAD/CAM process for program generation up to the finished work piece. The increasing complexity of modern components provides always more profound challenges to this delicate process chain for the production of the G code. Here, the concepts of "assembler of production" can directly be put in relation to the classic software development and raise interesting questions in the context of automatic program development, particularly in view of the approaching era of additive production methods by 3D printers. From this perspective, after a general introduction to the G-code programming language and an overview of typical processes, the talk grapes to the question, what challenges the CNC-controlled production of tomorrow already has to face today.

Why are some working software systems gradually becoming IT rescue cases? Would one have been able to see it coming or maybe even prevent it? What can you do if a software has become a rescue case? Why should you rely on modern approaches such as Kanban / Scrum and virtualization? If you are interested in these questions, then you are exactly in the right place in this practical lecture.

Software is everywhere today, and countless software products and projects die a slow death without ever making any impact. Today's planning and roadmap techniques expect the world to stand still while we deliver, and set products and projects up for failure from the very start. Even when they have good strategic plans, many organizations fail to communicate them and align everyone involved in delivery. The result is a tremendous amount of time and money wasted due to wrong assumptions, lack of focus, poor communication of objectives, lack of understanding and misalignment with overall goals. There has to be a better way to deliver! Gojko presents a possible solution, impact mapping, an innovative strategic planning method that can help you make an impact with software.

It started with "Four days Scrum coaching for the first team" and lasted three years in different roles - Scrum Master, PO, Lead PO. A project of this size (over 300 persons) faces one with some challenges; this talk will focus on the challenges in a large Feature Team growing to over 50 persons within the whole project.

Nagios, the most widely used monitoring solution, is in competition with APM tools and other commercial and OSS monitoring tools. But condemned live longer, with the Open Monitoring Distribution and check_mk plugin Nagios will finally be usable for mere mortals. The monitoring server and its plug-ins can now be installed with little effort thanks to OMD. Also the hosts that need to be monitored can be set up dramatically easier with the automatic service discovery and the web configuration interface WATO by the Check_mk Nagios plugin.

The integration of payment options / payment systems is complicated, cumbersome, slow and heavyweight. We at PAY.ON. have set ourselves the goal to refute this reputation and we have brought a new API - COPYandPAY - to market . We are thus part of a spearhead of a small revolution along with players such as stripe in the USA. Payment therewith becomes simple, modern and flexible. The dealer can concentrate on his core business and the integration of the payment options happens within minutes. A modern API and simple tutorials with "Try it out" function make this possible. New complexities such as mobile checkout options, 1-click payment, recurring payments, intelligent fraud prevention and the need to conquer new markets with local payment methods is already part of COPYandPAY - "Try it out!" Check it out during the session and find out for yourself - hands on - bring your laptop and join our LIVE programming contest and win an iPad mini! The exact goal will be announced at the beginning of the session. Participants should bring:

• Laptop with Internet connection, e.g. via the in-house WLAN

• For the development: text editor (for node.js) or Java environment (with Maven) of any choice

Almost every big enterprise with online business tries to design its applications in a way that they are always online. But is it also the case when we upgrade the database cluster? When we switch the whole data center? Based on a customer project we try to present common architecture principles that enable you to do all this without any service interruption and the most important: without any stress.
