Fixtures for the next weeks

written by Frank, on Oct 19, 2010 12:40:00 PM.

Some news from this side if my life.

I’ll be at the Samsung Smart TV Developer Day 2010 this week in Frankfurt.

Next week I’ve the pleasure to host a BoF named “Android and Its Impact On Home Entertainment and Home Automation” at this years CELF Embedded Linux Conference Europe in Cambridge, UK.

Returning from ELC-E I will head straight to elektro:camp(<<2010>>).

A barcamp in Kaiserslautern about

  • Smart Metering
  • Home Automation
  • Home Displays
  • …and much more.
It is the first of its kind and I’m really looking forward to this to learn more about and see what the folks from Flukso are coming up with.

And last but not least I’ll be in Munich on November 9th for the Google Developer Day 2010.

Droidcamp Stuttgart 18. - 19. Juni

written by Frank, on Jun 18, 2010 12:38:00 PM.

I’ll be there on Saturday and am particularly interested in the sessions:

  • Android for Business, the Dalvik VM and and the Java language
  • Android and Privacy - I like Android but don’t want to use my Google account
  • Smartspace - Indoor Localisation on Android
  • AndEngine - 2D OpenGL Game Engine
  • AndAR - Augmented Reality on Android

Stranded in San Francisco

written by Frank, on Apr 20, 2010 4:40:00 AM.

Having time to write a post here - doesn’t that sound very suspicious?

But this happens - more or less only - due to being “stranded” in the United States.

I was invited to do a talk about Mirabeau and Coherence at this years CELF Embedded Linux Conference in San Francisco.

Following that I had the pleasure to attended the Linux Foundation Collaboration Summit, which was co-located with the ELC.

Jim Zemlin - opening keynote LCS

Very remarkable talks in both conferences, met a lot of interesting people and gained quite some new insights.

And being already here I thought of adding one more weekend to do some sight-seeing, exploring the city, watch the annual Northern California Cherry Blossom festival, visiting Muir Woods, which I last had the chance some six years ago.

The one and only bridge
Cable car at Stockton/California
you don't see shops like this very often, and great ice-cream too
sushi & cherry blossoms
stone garden in the Golden Gate Park's Japanese Tea Garden
awe-inspiring trees, been there before the iPad and will be long after that

And along came Eyjafjallajökull.

Not only for me, pretty much all the flights of the European attendees of the conferences have been canceled. As mine was scheduled for todays afternoon I had some hope that it might be just in time for the European air space getting opened up again, but failed. Lufthansa seems to operate as of now at least partially from Frankfurt again, but Star Alliance partner United Airlines decided to keep their planes on ground.

After some first evil tidings - next possible flight to Europe would be 25th, no, 26th, no, hang on, not before 27th - Nadine, event manager of the Embedded Linux Conference - who, together with her team, did a really tremendous job in organizing the conference, managed to get me rerouted on a flight for Thursday 22nd.

Nadine, thank you so much!

Now I unintentionally will get the chance to see some of the United States airports - leaving San Francisco in the early morning, going to Denver, from there to Washington, changing plane there for the leg over the ocean, arriving in Zürich on Friday morning and, one last hop, should be in Frankfurt around noon.

Probably more endurance testing than travel, but never mind, it will get me home. And, not to be sneezed at, within my supply of insulin and blood sugar checks.

With that option available I decided to stay in my very comfortable room in the Kabuki in Japantown, use the wifi here to do some work and maybe even find time to check in some long outstanding Coherence patches, and enjoy some more days of Japanese food and culture.

Going to FOSDEM 2010

written by Frank, on Feb 5, 2010 5:50:00 PM.


Actually I just arrived in the really nice hotel in Brussels


after a remarkable unspectacular flight.

Will later meet Philippe for dinner and probably discuss some last-minute modifications - nah, just kidding - of our Mirabeau presentation about creating personal media networks and bridging UPnP over XMPP on Saturday 6th in the Jabber/XMPP dev-room at 16:00 o’clock.

Having dinner before the beer-event is actually quite a good idea™.

I’ll do another presentation on Sunday morning in the CrossDesktop room at 11:00 o’clock titled Coherence - the Digital Living room and beyond.

Stop by if you are at FOSDEM too.

This time I had planned to fly out on Monday evening, to have some time for sight-seeing, but we have decided to take part in the XMPP Dev Challenge.

So probably again no time for visiting the Atomium.


Let It Snow! Let It Snow! Let It Snow!

written by Frank, on Dec 13, 2009 1:44:00 PM.

On Saturday morning the kids got up shouting “There is snow outside!”.

Probably enough in the city to build one snowman, but it’s a start. ;-)

Unboxing confection

written by Frank, on Oct 10, 2009 5:45:00 PM.

I was sailing around Sardinia a few days ago and bought as a bring along some Sardinian sweets - Sorrisi di Sardegna di Mirto, Mandorlini (Pasta di Mandorle) and Bucconettes Mirto.

Besides these handmade goodies being extremely delicious - unwrapping them is already an experience.

going to GCDS

written by Frank, on Jul 5, 2009 4:30:00 PM.

Well, not quite yet. Again a heavily delayed fight, but at least not canceled yet.

My plane was supposed to leave today at 13:20, apparently it is broken and they need to get a replacement aircraft over. My confidence in Condor is a bit shaken.
But at least they handed out two 10€ coupons for food and beverages - that will allow me to throw a party here if I can’t make it to the one on the island tonight. ;-)
For the moment I made myself comfortable in a small bistro here with my own power-outlet.

Departure is now scheduled for 20:00, meaning I won’t be in Las Palmas before midnight.

Anyway, hopefully being there ready for the talks on Monday morning. The talk Philippe and I am giving is on Tuesday morning, which I’m now somehow quite happy about.

Pont Mirabeau - an UPnP bridge

written by Frank, on Jun 30, 2009 10:56:00 PM.

What started over a year ago as a vague idea and got more concrete in a first prototype last October, is now ready for a first public beta - Mirabeau, an application level proxy for UPnP devices using XMPP as a transport to establish a connection between two or more local networks over the Internet.

Or in less technical terms, it allows the DLNA capable TV at your parents place to access for instance the images of your last vacation stored on an UPnP MediaServer in your home.

Mirabeau is part of Coherence and utilizes the D-Bus interface there to create a transport layer over XMPP with the help of Telepathy’s tubes.

Philippe and I will give a presentation about it during this years Gran Canaria Desktop Summit.

Mirabeau addresses the issue that UPnP is only meant to be used in a local network. With Mirabeau we are able to easily interconnect two or more networks and the UPnP devices therein. All that with a simple, well-used setup - Jabber, and without the need for complicated VPN-tunnels or similar techniques.

Philippe wrote already about our first successful - world premiere - connection with our two networks in Spain and here in Germany, where we tested the whole infrastructure with the UPnP-Inspector.

What I would like to highlight here is the point that arbitrary UPnP devices do participate in this.
Mirabeau is a transparent bridge for UPnP devices on the application level, not only an ‘I can share my media collection between two instances of the same software’ setup.
Which is of course nice too, but we lifted that to a more higher level and instantly integrate everything that can talk UPnP - PS3, Xbox 360, Totem

An unmodified UPnP application on the N810 - Nokia’s MediaStreamer is browsing Phil’s server in Spain.

And the same by a Playstation 3:

BBQ experiments

written by Frank, on Jun 19, 2009 5:16:00 PM.

Last weekend we had some friends over at our place for a little barbecue.
Among the “ordinary” steaks we prepared:

  • chicken and rocket bruschettas
  • salad of prawns, peas, celery and mint
  • king prawn spits, marinaded with chili and ginger
  • brown mushrooms and porcini, chopped spring onions, thyme and cream in preserving jars
  • grilled asparagus (green) and spring onions, with a tomato, mozzarella, olive oil and honey dressing
  • punch with strawberries, oranges, tonic water and Aperol
BBQ jars
Just some stimuli for your next BBQ. ;-)

working at (train à) grande vitesse

written by Frank, on Jun 6, 2009 9:31:00 PM.

I’m usually not using trains, the city I live isn’t that well connected to the German railway system, so usually I’m faster by car or for longer distances I go by plane.

But for the travel from Valras-Plage to the Trophees du Libre in Soissons I had chosen to use the TGV - there is a direct train connection between Beziers and Paris that covers the distance in a bit more than four hours.

I booked première class - it was only a few €s more than seconde, and I had learned from my trip to Paris for the KDE/Coherence sprint that there is no power outlet at the seats in the second class in a TGV.

The ambience in the train was very decent. A lot of space - I had booked a single seat with a table, no people yelling into their mobiles, more or less all have been muted, and everybody speaks with a lowered voice.

In that pleasant atmosphere I used the ~ six hours time to work on some of the loose ends in Coherence.

  • creating a picture-frame MediaRenderer that should serve as an example on how to implement a simple MediaRenderer
  • the implementation of a Digital Security Camera device, based on the general purpose GStreamer pipeline element from the TestStore backend
As you might see on the first result, I’m quite pleased with it.

And I do now understand people a bit better who always told me how great traveling by train is.
