Dr. Pinker has been listed on TIME magazine's "100 Most Influential People in The World," as well as on Foreign Policy’s list of "The World's Top 100 Public Intellectuals". He has received awards and honors from the National Academy of Sciences, the Cognitive Neuroscience Society, and the American Psychological Association.
Since joining JetBrains in 2003, Dmitry Jemerov has worn a lot of hats in the company. These days, he leads the development of PyCharm, an IDE for Python and Django, and is a co-lead of IntelliJ IDEA, the company's flagship Java IDE. He also contributes to the development of Kotlin and has created the initial implementation of the Java bytecode generator for the language.
Programming is hard. Programming correct C++ is particularly hard. Indeed, it is uncommon to see a screenful containing only well defined and conforming code. Why do professional programmers write code like this? Because most programmers do not have a deep understanding of the language they are using. While they sometimes know that certain things are undefined or unspecified, they often do not know why it is so. In this presentation we will study small code snippets in C++, and use them to discuss the fundamental building blocks, limitations and underlying design philosophies of this wonderful but dangerous programming language.
Olve Maudal works for Cisco developing telepresence and video conferencing products and solutions. He loves to write code, but is just as interested in how software is developed as what it actually does. Previous experience includes developing systems for finding oil (Schlumberger), and developing systems for electronically moving money (BBS). Based in Norway, Olve is also an active member of the vibrant geek community in Oslo where he has been involved in JavaPils, Cantara, XP Meetup, Oslo C++ Users Group, JavaZone, Lean Meetup and a few other things. He blogs at http://olvemaudal.wordpress.com/ and tweets at http://twitter.com/olvemaudal.
Possibly the greatest strength of a statically typed language is that it can prevent large classes of bugs from ever compiling. But even with a strongly typed language such as Haskell, APIs can be designed that do not properly take advantage of the type system, and therefore reduce the compiler from a powerful robustness tool to a nuisance. Based on experience in creating Yesod's type-safe interfaces for URLs, data persistence, and templating, Michael will discuss various techniques to make solid, reliable APIs, using such Haskell features as associated types, phantoms, and GADTs.
Michael Snoyman is the lead developer of the Yesod Web Framework. Now approaching three years of age, Yesod's mission has been to introduce the strong static guarantees of the Haskell language into the web programming world, while keeping the rapid development approaches programmers are used to. Michael is the author of the O'Reilly book, "Developing Web Application with Haskell and Yesod". He is based in Israel and works for Suite Solutions, where he provides Haskell and Yesod based solutions for a number of their largest clients.
Profiling is fun - and yields results.
René Bruns is Technical Director Games Development at Travian Games GmbH.
Within the software development field, "big data" is used as a term to denote data volumes that grow so strongly and/or have to be analysed so fast, that novel approaches are required to deal with them. Using specific examples from the telecommunications field, we show how current technologies like Apache Hadoop or Amazon EC2 can be used to generate new insights - or even new business models - from existing data. We talk about some of the challenges faced during these projects, including their solution.
Bernhard Bock is Principal Consultant at TNG. He holds a diploma in electrical and information engineering from the Technical University of Munich.
Christoph Stock is one of the founders and managers at TNG. He holds a diploma in physics from Ludwig-Maximilians-University of Munich.
In our omnipresent information society, it is essential to process the rapidly growing, unstructured corporate data, so that users can access their relevant data as quickly as possible.
There are several open source software projects which can centralize heterogeneous corporate data that are distributed over a variety of IT systems. One important software platform is Apache Solr, which builds upon the Lucene search engine and simplifies development of Lucene-based applications.
This talk demonstrates how quick searches can be realized with the help of Solr. We will integrate Solr with Apache Nutch, which allows us to index, structure and display several million documents from the web usind commodity hardware. Today, these technologies are used successfully by thousands of companies, such as AOL, IBM, LinkedIn and MySpace.
Martin Förtsch studied computer science and applied natural sciences at Hochschule Merseburg. He works as a senior consultant for TNG and, apart from software development, is also interested in business intelligence and system administration.

Many organizations are child-like. They plan the project as if nothing will go wrong, and when something does go wrong they act shocked and dismayed. Risk Management is not just worrying about your project, and it is not about running away from risk. Risk Management for software projects is all about when you make decisions and when you take action. When done to its greatest advantage, Risk Management starts before a project is even born. (How do projects get started in your organization?) In this talk Tim Lister will present the advantages, and the dangers, of practicing Risk Management in an adult-like fashion. He will offer up a process for you to consider tailoring for your organization, and he will discuss how your organization can grow up.
Tim Lister is a principal of the Atlantic Systems Guild, Inc., based in the New York office. He divides his time between consulting, teaching, and writing. Currently he is working on tailoring software development processes using software risk management techniques. He has been an invited speaker at the Agile Development Conference three times. Tim was a guest lecturer on software risk management at the Stanford University School of Business, and gave the Dean’s Lecture at the Rochester Institute of Technology. He was a member of the Airlie Software Council, a group of industry consultants, advising the DoD on best practices for software development and acquisition, and is a member of the Cutter Business Technology Council.
Tim, along with the other 5 Principals at the Guild, is co-author of Adrenaline Junkies and Template Zombies: Understanding Patterns of Project Behavior, (Dorset house, 2008). He is co-author with Tom DeMarco of the text, Waltzing With Bears: Managing Software Project Risk, (Dorset House, 2003), which won the Jolt Award for best general computing text in 2003-2004. Tim and Tom are also co-authors of Peopleware: Productive Projects and Teams, 2nd ed. (Dorset House, 1999). Peopleware has been translated into ten languages. Tim Lister and Tom DeMarco are also co-editors of Software State-of -the-Art: Selected Papers, a collection of 31 of the best papers on software published in the 1980’s (Dorset House, 1990).

He also serves as a panelist for the American Arbitration Association, arbitrating disputes involving software and software services, and has served as an expert witness in litigation proceedings involving software problems.
Agile methods such as Scrum or Kanban are increasingly becoming mainstream. They are often perceived solely as a set of process mechanics. To gain the full benefit of agile methods, however, a holistic approach must be taken. Scrum and Kanban have their roots in the Japanese philosophy of "Kaizen" - better known in the western world by the more formal Continuous Improvement Process (CIP) of the 1950s. This talk introduces the principles of Kaizen and highlights the aspects relevant to software development. In addition to reflecting on the requirements for a fully functional Kaizen culture, some real-world examples will be presented.
Eike Reinel is one of the founder partners at TNG. His main focus lies in the area of Scrum Coaching (CSP + CSM), Kanban and Agile Software Development, in the area of classic project management, as well as in software development in enterprises. He studied Computer Engineering at the University of Applied Sciences in Munich.
Scrum with one or two teams is well-proven in many cases and the Scrum framework gives detailed guidelines for this situation. For larger projects it provides less concrete guidance. By now there are concepts, which address the challenges of large-scale projects, such as Scrum of Scrums, feature teams, requirement areas, virtual teams, and dependencies amongst others. Which of these concepts work well and which do not, and how they can be put into practice, is discussed in the talk based on the experience from a project with 15 teams.
Sebastian Stamminger studied mathematics at LMU Munich and received his PhD from the Jacobs Universität Bremen. He is a principal consultant at TNG. He is focussing on consulting, analysis and project management in agile IT.
Dr. Mathias Münch und Jörg Meltzer, TNG
The vSphere Perl SDK enables you to create virtual machines entirely programmatically, Kickstart to install a guest operating system, and CFEngine to configure it. For the first time, the whole chain from creating the virtual machine to having a complete, running service can be automated by software. Now, data centers are no longer installed, configured and administrated - they are programmed. The core principles of software development can now be applied to administration. Test-driven development, continuous integration, testing and staging are now available to systems which were previously hand-crafted. All these principles are being implemented successfully at a project with a large, German internet service provider. This talk describes tools, design decisions, as well as what is possible today, and what isn't.
Mathias Münch studied physics at the TU Munich and has been awarded his PhD there as well. He is a senior consultant at TNG. His focus is with data centers and network design.
Jörg Meltzer studied computer science at the Freie Universität Berlin, next to working part-time at the Konrad Zuse Center for Information Technology. He is a Senior Consultant with TNG and focuses on software development as well as system administration and business intelligence.
Prof. Dr. Stefanie Scherzinger, Hochschule Regensburg
Every Internet start-up soon has to ask the question - where should we host our web application? Scalability is an important consideration for selecting a provider: if the new application has the desired success - or even exceeds all expectations - the young company's growth must not be inhibited by hardware bottlenecks. At the same time, financial constraints prevent large, up-front hardware investments. Providers of cloud-based, platform-as-a-service solutions offer a practical answer: the cloud provider supplies a complete runtime environment for web applications, administrating all resources while guaranteeing scalability. Only the computing time and accumulated storage space actually used are billed. This allows the application to grow with its users, keeping the operational costs in proportion to that growth. The start-ups development team can concentrate on application functionality instead of web server administration. In this talk we will focus on the concepts behind platform-as-a-service. We will examine the architecture of the Google App Engine and establish an understanding of the implications this architecture has on the development process. Additionally, we will explore several data storage interfaces available in the Google Cloud and how they provide scalability.
Stefanie Scherzinger is a professor at the University of Applied Science in Regensburg. She gained industry experience as a software developer with Google and IBM Germany. Her areas of interest lie with databases, XML processing and new query languages, leading to her promotion at the Saarland University with an emphasis on storage-efficient processing of XML data streams.
Hans Dockter, Gradleware
Almost all enterprise software projects are component-based. One would like to steadily test the dependencies of these components through early integration. At the same time, this often hinders the continuous building and promoting of the complete application. To find satisfying solutions that scale without switching to a late, mostly woebegone integration is an important factor for the project’s success. We consider typical sticky points as well as the latest solution strategies. As an example, we take a closer look at a real project with 500 developers and 50 components. We get to know an open source tool that can be used to implement the introduced solution strategies in a classy and powerful way.
Hans Dockter is the founder and project lead of the Gradle build system and the CEO of Gradleware Inc, a company that provides training, support and consulting for Gradle and all forms of enterprise software project automation in general.
Hans has 13 years of experience as a software developer, team leader, architect, trainer, and technical mentor. Hans is a thought leader in the field of project automation and has successfully been in charge of numerous large-scale enterprise builds. He is also an advocate of Domain Driven Design, having taught classes and delivered presentations on this topic together with Eric Evans. In the earlier days, Hans was also a committer for the JBoss project and founded the JBoss-IDE.
A fundemental difficulty with implementing a message-oriented interface to a third party are the unerderlying dynamics, which are often not fully described in the specification. This can lead to an unexpected or surprising message order, which must be countered with immediate changes to the application. The order interface of a large telecommunications operator presents such a message-oriented interface. The risk of interpreting the interface differently is increased by a mandatory compliance test which must be passed within certain time and quality constraints. To mitigate these risks during development of the SOAP interface at M-Net Telekommunikations GmbH, the project team switched their IT landscape from a manual deployment process to a automated delivery pipeline. To achieve this, the team extended the existing continuous integration environment to an automated delivery process. On each code commit, a full build - including unit and service tests, as well as automated static code analysis - is performed. After testing, the JEE application is automatically distributed to four separated servers. In this environment, automated integration tests run subsequently and verify the application against an interface simulator. Finally, the built artifacts can be deployed to production with a single click. Jenkins, Ant/Ivy and Artifactory provided the technological foundation. This talk demonstrates the obstacles the team encountered on its way to continuous delivery, and how they were overcome.
Joachim Glink has been working as a software engineer for M-net Telekommunikations GmbH for 8 years. He spent this time designing, developing and maintaining one of the core JEE applications for (technical) order maintenance and provisioning.
Stefan Wolf studied Mathematics at the TU Munich and did his PhD at the University in Paderborn. He is a senior consultant at TNG. His focus is on build- and deployment automation, as well as on design and development with Java EE.

Arnout Kazemier is the founder of Observe.it, a company that he started after winning the Node Knock Out 2011 which allows you to follow and observe your visitors' browsing behaviors. He's also one of the core the developers of Socket.IO, one of the biggest real time libraries for Node.js, and loves building high performance, scalable real time systems.
Dr. Andreas Werner, Max-Planck-Institute for Plasma Physics
The continuously rising energy hunger of modern societies dictates the exploration of new energy sources. Nuclear fusion is one important future option to address this task. Similar to the sun, the fusion of hydrogen isotopes is intended to be used for energy production. If it were possible to open up this new primary energy source, a safe and environmentally sound energy source would have been created for a million years of more.
Such nuclear fusion reactions can be created in very hot plasmas with temperatures of about 100 million degrees and plasma pressures of several bars. Contrary to the sun, the plasma is locked in by magnetic fields in order to isolate it from the cold walls of the container. Wendelstein 7-X is currently under construction in Greifswald and is scheduled to become operational in 2014. The novel concept promises the economic operation of later fusion power stations. Plasma confinement will last half an hour, enabled by superconducting magnetic coils, resulting in a significant improvement of the experiment compared to its predecessors.
New challenges have to be faced for data acquisition and control, too. The plasma diagnostics are expected to create streaming datarates of 30 GBytes/s, which have to be permanently archived. Partially, they have to be analysed in real-time for control purposes. The typical doubling of the data rates within one to two years requires horizontally scalable data center structures. Additionally, the development of an intelligent and adaptive plasma control will be a subject of research, in order to stabilise the plasma against changes in the border conditions, for example magneto-hydrodynamic properties. Data analysis and modelling will be based on Bayesian methods to automate complex data analyses and to develop safety signals based on inexact sensory information.
Andreas Werner earned his PhD at the University of Gießen in the area of atom impact physics. After 4 years of research at the stellarator experiment Wendelstein 7-AS in Garching, he dedicated himself to the construction of the successor "Wendelstein 7-X" in Greifswald and developed diagnostics for magnetic field measurements and leakage of energetic ions. Since 2007 he is heading the Control, Data Acquisition and Communication department, which develops and supplies a distributed control system, data capture and central IT services. His current interests focus on plasma scenarios, SOA, virtual HPC, Bayes inferences and good electronics.
Daniel Schmidt, University of Kaiserslautern
Some insights into the THOR project will be presented, which involves the modelling and semi-autonomous control of an 18-ton mobile bucket excavator from Volvo Construction Equipment.
Daniel Schmidt was born in 1983 and finished his final secondary-school examinations in 2002. After his civilian service he attended University of Kaiserslautern from 2003 until he graduated with a degree in applied computer sciences (Dipl.-Inf.) in 2009. He wrote his diploma thesis concerning "Soil Simulation and Behavior-Based Control for Landscaping Tasks of an Autonomous Bucket Excavator" at the Robotics Research Lab.
Since June 2009 he is doing his Ph.D. in the context of the autonomous excavator project THOR (Terraforming Heavy Outdoor Robot). The focus of his work are the simulation of soil on Graphics Processing Units (GPUs), behavior-based control architectures, and planning algorithms in the area of (autonomized) excavation pits.
On the 21st of October 2011, Thomas Senkel from the e-volo team (www.e-volo.de) succeeded in building the Volocopter VC1 after more than one year of development, the first manned flight with a solely electrical operated and vertically starting aircraft worldwide. The invention of the Volocopter and the first flight with the VC1 have been celebrated as pioneer work in aviation in numberless TV- and press releases all over the world.
In contrast to any other aircraft, the handling of the Volocopter is very easy. The automatic position control and the directional control (fly by wire via joystick) are carried out with several independent and one another monitoring on-board computers, regulating each electric motor in its agitator speed separately. Besides the convincingly easy architecture without complex mechanics (no pitch-control), the redundancy of the drives is another considerable advantage. Thus, even in case of a breakdown of several motors, the Volocopter can be landed safely.
In this talk there first will be given a short historic summary of the development of the first helicopter. The history of origins of the Volocopter VC1 is presented with many images. An insight in the underlying physics shall show, why the VC1 was configured and dimensioned as it is. At least, a future prospect in the planned further development of the Volocopter will be given.
Thomas Senkel studied Physics in Berlin and Oldenburg, with a major in regenerative energies. Since 1996 he has been operating his research office Senkel (www.forschungsbuero.de) and has been employed in different projects regarding the electric drive in ultra-light vehicles and aircrafts as a freelancer. Thomas Senkel has been a passionate paraglider pilot for a long time and he holds a UL license.
We will see the creative processes to create these 3D animations: “Inspirations”, “Nature by Numbers”, “Isfahan” and “Snakes”, works where we find a connection between arts, maths, architecture, geometry, nature and of course: M. C. Escher. These creative processes are not exactly the same in all cases, but we can establish some common guideline
The talk will be absolutely based on images and video screenshots, starting with the shorts projection.
