Well, is e-mobility dead or what? What are the current problem areas and what kind of solutions are companies developing right now e.g. with respect to intelligent charging? Are e-cars economically feasible for companies? Can you go across Germany with an e-car? Learn more about e-mobility at our first E-Mobility Day at HdM with talks from Fraunhofer IAO, Vector Informatik and BridgingIT.

We are closing the seminar on concurreny and parallelism with a little workshop. A case from the industry will be discussed in the context of several different technologies.

Indi development, new gesture recognition interfaces, multiplayer technology, asset creation for virtual reality and of course: lots of demos and previews at our next games day.

Just a few comments on our talks. There is more to come in fall 2015, when our second Language Day will take place. We will have talks on Javascript, C#, Rust and functional languages.

Given the sad state of IT-Security, it is about time to fix the basics...

Still our most important tool - the programming language, is undergoing drastic changes. New paradigms are introduced, new languages pop up almost every week. What makes a good language in Internet times? Fit to support agile development, continuous delivery and increasing demands for security and usability. Learn about new developments in our first language day. The next one in the winter will probably cover Javascript, C# and Rust/Dust/D.

In this post-Snowden area we are taking a close look at secure software, critical infrastructures and ways to conquer the threats to critical infrastructures and individual exposures. Specialists from 1&1, Bosch and mpc are joining us for this long overdue event.

A bit more technical than the last ones, this games day will deal with advanced concepts in realtime lighting, physically based rendering, games on smart watches and artificial intelligence in games.

It was about time for a repeat of our Developer Days at HdM. This time we will have three talks about software design, architecture and frameworks for successfull enterprise software. All based on many years of practical experience with difficult decisions regarding designs. Join us for this interesting session. Developers, architects, consultants and project managers as well es members with akademic background welcome!

Is the future of games in virtual reality? What is the current state of VR? How does it feel to play a game made for the Oculus Rift? (In case you don't own one: how about building your own? Take a look at the latest gadget from Google I/O . How does it feel to develop a game for virtual reality? Get some background information and practical know how at this games day. And discuss your vision of the future with us. Please notice the change in the agenda: we'll let you watch another game at the end (:-)

Get a better understanding of your visitors! Learn how to collect and analyse behavioral data. Meet tool vendors and users of analytic tools and learn how to test your business profile.

What can you learn from looking at search requests leading to your platform? You are running youtube videos - did they help to increase the number of visitors? There are many things you can learn from analysing the behavioral data of your visitors. But before you can do so, you must collect the data and learn to use the tools needed for analysis and reporting. They are a must for a successful site or blog. In case you are just a user of internet sites, you can get a better understanding of data collection on the web and why it is - to a certain degree - absolutely necessary for sites.

Talks and discussions on current legal affairs around the Internet. Intellectual property rights, escpecially software patents, the NSA and Anonymous and last not least the Redtube streaming scandal. In all these cases, technological opportunities meet economic stakeholders on the battle field of laws and legal actions. And not every technology is legal and not every legal claim is justified.

It's all about speed: how to build fast and responsive web applications, quick application design within the browser and last but not least the realtime and peer-to-peer features of the new WebRTC standard. The 7th webday at HdM lets you meet with experts in those areas and extend your knowledge of HTML5.

Im Rahmen des Tags der Lehre an der HdM halte ich einen kleinen Vortrag zu meinen "Days".

Mittwoch, 4.12.2013 um 16.45 in 013 in der Nobelstrasse 10, Stuttgart-Vaihingen. Der Talk "Blick über den Tellerrand" beschreibt ein wenig die Hintergründe, Zielsetzungen und Tricks.

The image shows a solution for a rather hard problem: capturing live discussions with little equipment and almost no manpower. And to top it off: in any room. So we are talking a mobile solution too.

This week I realized, that splitting up requests into tens or hundreds of subrequests is still a rather hard problem, due to the long-tail distribution of response times. A portal is a typical fan-out architecture. In 1999 I found some solutions for fan-out like controlled backends, replication and incomplete (tainted) requests. Google of course goes much further today.

Strictly timed requests, distributed loads and a close look at everything from the CPU over network buffers, data structures in memory etc. are in the toolbox.

You think milliseconds is fast? Think again. Think about putting algorithms into FPGAs. Think about creating algorithms that fit into L1 caches. Algorithms which do not need much memory and which do not touch data more than once. Learn about the use of one-pass algorithms from HFT. And start thinking about all the places in our computing infrastructure, where latency hides.

Is the Internet a good model for power grids? What can energy engineering learn from IT and what should it better do in its own ways? Which patterns work in both areas? What makes a robust solution? This is a short talk on some ideas gained from the Smart Grids Week in Salburg this year. Cultural and technical aspects are covered in my talk on Blackout - on the role of IT in Smart Energy Grids .

Christian Teutrine, Senior Managing Consultant with Global Business Services, IBM will give a talk on practical experiences with MDA, made in a large project which took 7.5 years from the concept phase to the go-live. 80% of the code had been generated. Mr. Teutrine had the role of a business lead architect in this project, and in his talk, he will look at it from a business architecture point of view: How does MDA influence the contractual situation? The project management? Can agile methods be used with MDA? How well does it work over the years? What if off-shore employees join the project?

This talk is a rare chance to get first-hand experience on the interplay between business and technical aspects in a really large project. It is not so much a technical talk.

How does Amazon know what we want? Learn about advanced recommender systems which use clever algorithms to match users and items. See how math and computer science shape modern marketing.

It was more than time for a re-structuring and renovation of my site. I considered changing to wordpress but finally decided to stick with my xml-based generative approach. But instead of generating my own navigation I am now using CSS3 (without any javascript) for it. Now comes content cleanup...
