The planning process started way earlier than last year but as usual some things remain until the very last minute before everything starts. But since this year the teamwork and enthusiasm was extraordinary we finally made it almost as planned. We surely did not reach our goal of releasing the recordings hours after the talk ended. Mainly because we underestimated the amount of knowledge and pain it took to actually get the recordings running on the iPod. It was one of the guidelines for this years official recordings: they had to run on current generation video iPods and they had to have all the metatags. So the team did it and we ended up releasing the first half (nearly) of the 23c3 recordings into the public only 2 weeks instead of the 4-6 months of last year. Even better: we managed to improve the video quality and even got smaller files. That wouldn’t been possible without the encoding-pipeline knowledge that Michael Feiri brought into the team. With that knowledge it also took several days to actually build the working pipeline.(yes the iPod is one special piece of hardware) The complete encoding-pipeline we used will be documented and released soon.

So after all that planning we finally packed our stuff and hit the road:

After some hours and the unpacking the video studio looked like this:

here’s a close up of the Windows Media Encoders, the h.264 encoding machine and the storage (all from behind):

So we surely brought enough processing power to berlin. And this is what did take the picture:

BTW: the black machine in the background just
died during the keynote speech…

Want to see what it’s like watching “out of the window” of the video studio? No problem:

or how about another view of the studio:

So. So you had some pictures of the video studio and the setup. But I bet you want to know some more details about the setup itself. I created an overview for you:

Since last years setup was completely digital (planned) and we ended up using the DV-tape backup since all the recordings were screwed up we thought it might be a good idea to go back one step and use analog video as in FBAS to transport and record the talks. We also had the DV-tape backup this year and to be honest in some cases we have to fall back to that. Less than 10 out of 130 recordings are screwed up so we have to use the DV backup. That means 120 of them worked out as planned. Great! We are currently cutting and encoding them and as you read this more than half of them should be up on the official servers and the mirrors.

Now in the aftermath of the congress we learned a new lesson: there’s maybe one or another speaker that would not allow us releasing their talk recording. In the future we think of having something like a “don’t record me”-list to avoid misunderstandings.

It’s done.

The first 53 recordings of the 23c3 are currently uploaded to the server. The remaining ones will be available in the next few days.

The event is over and it was great! More than 7 hours of new information compressed into 8 talks were presented today. If you missed the event, don’t worry: you can download the slidedecks here and of course if you like, you can participate in another University-Roadshow 2006 event in another german city (complete list and subscription here). If you like to attend some more talks at the TU-Ilmenau you can watch out for the local community website: www.dotnetcommunity.de – Since we’re in the process of building a INETA .NET Community here in Ilmenau we’re planning several events in the next months. Oh, to name one: on the 25th and 26th of next month there’s a ASP.NET workshop, held by my colleague Nico Orschel. More information on that can be found on dotnetcommunity.

The Slidedecks are available in three different formats(german language versions only):

Windows Vista für Jedermann (Daniel Kirstenpfad):

Tomorrow the US TechEd takes off. If you cannot attend personally you can attend it virtually. Microsoft hosts a website called “Virtual TechEd” where you can watch talks and keynotes via streaming video. Beside watching the talks you can listen to the TechEd radio livestream.

Berkeley University of California just made a great number of their audio courses available for free download on iTunes. Just tune in and get a taste of cal.

I actually got a taste of the incomparability of two universities… The courses are great!

But Berkeley is not the only university which has some sort of online-courses. FeM e.V. offers you a growing number of complete courses of the TU-Ilmenau with video+audio.

So here are some news about the 22c3 recordings:

According to the last information I got, 130 of 146 recordings are ready to go. I don’t know why the team decided to release them all at once only but unfortunately you’ll have to be patient.

The release is planned for THIS WEEK. So stay tuned and check back for more information.

So here we are. The January passed by and still no recordings. What happened?

picture by namenlos

Straight after the congress we started working on the recordings – but soon we realised that almost all of the recordings we made live with ffmpeg and his friends were corrupted: The audio and video is just not in sync.

Well it would be easy if it was just shifted for a given amount of time – but the amount of shifting time is changing all through the recordings.

So we engaged DEFCON 4 and got back on our backup solution that is there, just in case something would go wrong. (who would have thought that?!).

So what’s DEFCON 4? We came to the congress with 400 brand new DV tapes. And that’s simply what our backup solution is: everything that was recorded during the 22c3 is on DV tape. And it’s in sync there.

So we are extracting nearly all of the recordings from those DV tapes…

And as you can imagine: this takes some time. It takes less time than we’d expected – we are making serious progress. Together with the CCC it was decided that an intro and outro should be added to each recording – that also takes some time. If you are experienced in creating scripted/batched DV material with definable text… we obviously need your help

So when will the recordings be available? We hope very very soon. Like I said we are making good progress in getting the stuff off the tapes, but it’s very difficult to give a time frame. Check back here or on the official 22c3 FeM Homepage for updates – … well if we can get the intro/outro issue working fast it’ll probably be only days away.

If you have any comment, feel free to comment here.

So here we are: a new year and just two days after the 22c3. As we can tell everything was recorded as planned and everything went just great.

I want to tell everybody who helped to make this happen: Thank you very much. It was a pleasure and great fun to work with you guys. The results that we all together achieved speak for themselves: nearly 1 Tbyte of downloaded live-stream bytes. Nearly 400 listeners on our streams at peak times.

In fact there is a lot to do afterwards: We have to cut the MPEG2 files (5 Mbit) of each lecture to set start and end-times correctly. We have to tag them and make them available (1 to 5 gigabyte each) for you as soon as possible – which means when the last hard drive arrives from berlin here in Ilmenau.

When all MPEG2 files are complete we complete our MPEG4 encodings – which means: we are already encoding everything we have in MPEG4 1.2 Mbit.

This is our main focus at the moment. It should be possible to make everything of the above mentioned available within January. After all this is done (or maybe in the meantime, we don’t know at the moment) the remaining WMV on-demand streams will become available as we have to reencode. So check back here to get more information and updates about this topic.

I often was asked why the WMV on-demand streams were only available for the first day: the answer is easy – we tested if it’s feasible to cut them nearly live – and we came to the conclusion that it raises the stress bar for our team to high to handle it the complete 4 days of the conference. So we changed our plans to ensure that you have a mostly flawless live-streaming experience.

At the end: Here is the list of the people I want to thank for their support and help at 22c3 (without any order actually):

laforge and his team, maedness, mucki, namenlos, manu, cosrahn, Agtmulda, yray, cutcat, ecki, ahzf, ambanus, somi, all the video and audio angels that made the great audio and video possible, Ambion for the great support, the POC who helped were our cable guys and supported us even with coffee, the NOC which made IPv6 happen finally and made the best conference network ever possible…. and a whole lot more people I forgot.

Scanning your GPRS/UMTS IP network for fun and profit

We are giving an overview of ip networks used for >=2.5G technologies. Our main focus is on scanning the overlaying ip network, on different Voice-over-IP filter implementations and the possibilities to circumvent them.

We want to explain the ip networks used in GPRS and UMTS cellular networks from the enduser point of view. How do they work today and what has to be done to get a normal webpage, voice-over-ip or even a video stream onto your PDA or SmartPhone.

For your private investigations inside your providers ip network we want to demonstrate you a tcp/udp port and round-trip-time based traceroute program based on the .NET compact framework. With the help of this program we want to analyse the anti voice-over-ip filters implemented by different cellular providers and show you some possibilities how to circumvent them _efficently_. So we don’t just tunnel all the traffic through a VPN. But even when these filters become more sophisticated in the future we want to present some ideas how to defeat your right to talk via voice-over-ip whereever and whenever you want to.

Nico held is talk this friday – and here are his slides for you to download.

It’s time for another What The Hack wrap-up session: (slides are in german)

Slides: WTH_Bluetooth_Security.ppt (801 KB)

My slides are based on Martin Herfurts talk at the What The Hack 2005. You can get his slidesdeck at trifinite.org.

Nico wrote a cool article about the TerraServer WebService and how to use it with Visual Studio 2005. He uses this WebService in his talks as a WebService example – a great idea: The problem is now, that the example sourcecode does not work under Visual Studio 2005. So he changed it to work – and you can download the new sourcecode here.
