Photosynth now mobile…

It’s been some months years since the once Microsoft Research Project got public and Microsoft started offering it’s great Photosynth service to the public.

I’ve been using the Microsoft panoramic and Photosynth tools for years now and I tend to say that they are the best tools one can get to create fast, easy and high-quality panoramic images.

There is to store all those panoramic pictures like this one from 2008:

The photosynth technology itself contains several other interesting technologies like SeaDragon which allows high quality image zooming on current internet connection speeds.

This awesome technology is as of now available on the iPhone (3GS and upwards) and it’s better than all the other panoramic tools I’ve used on a phone.

TechEd Europe 2010–if you’re there we could meet!

After 5 years of TechEd abstinence it’s time to visit the conference again. This years TechEd will be held in Berlin which is quite nice since traveling will be reduced to a minimum. Since the session schedule is already available I’ve already filled my calendar for TechEd week.


Okay it’s impressive to see that so many interesting sessions can be held in one week’ – the bad thing is that I need do decide which to go and which to watch on video later.

On later notice: Since I will be there it would be a great opportunity to meet. Let me know if you are there and want to meet.

Windows Live Writer 2011 is available…

I am a huge fan of the Windows Live Writer. It’s been some years now since Microsoft made this free tool available to bloggers who want to blog on Windows. And in a bold move Microsoft announced the other week that they will be moving all Windows Live Spaces weblogs (a free weblog hosting service) to WordPress.

In an accompanying step they just released the 2011 version of the Windows Live Writer. Actually I think it’s a shame that there is no comparable tool on Mac OS X … which is quite unusual since those types of tools in that quality are more common on the apple platform.

The new Window Live Writer 2011 comes with the Ribbon UI already known from Office 2007 and 2010 (and 2011 now).

Using Windows Deployment Services (WDS) to install Linux over Network (PXE)

Developing software is hard work – especially when you target several operating systems. One task that you have to perform quite often would be to deploy a new installation of an operating system as fast as possible on a test machine.

Doing this with Windows is easy – you can use the Windows Deployment Services to bootstrap Windows onto almost every machine which can boot over ethernet using PXE. Everything needed to make WDS work on a Windows Boot-Image is located on that image. Since it’s that easy I won’t dive into more detail here.

What I want to show in greater detail is how you can use WDS to deploy even Linux over your network.

Step 1: Get PXELINUX

What’s needed to boot Linux over a network is a dedicated PXE Boot Loader. This one is called PXELINUX and can be downloaded here.

“PXELINUX is a SYSLINUX derivative, for booting Linux off a network server, using a network ROM conforming to the Intel PXE (Pre-Execution Environment) specification.”

On the homepage of PXELINUX is also a short tutorial which files you need and where to copy them.

Step 2: Setup WDS with PXELINUX

I suppose you got your WDS Installation up and running and you are able to deploy Windows. If that’s the case you can go to your WDS Server Management Tool and right-click on the server name – in my case “fileserver.sones”. If you select “Properties” in the context menu you would see the properties windows like in the screenshot below:


You have to change the Boot-Loader from the standard Windows BootMgr to the newly downloaded PXELINUX bootloader. Since this bootloader comes with it’s own set of config files you can edit this config file to allow booting into Windows.

Step 3: Edit PXELINUX configuration filewds-pxelinux-2 

The first entry I made into the boot menu of the PXELINUX boot loader is the “Install Windows…” entry. Since the first thing the users will see after booting is the PXELINUX loader menu they need to be able to continue to their Windows Installation. Since this Windows Installation cannot be handled by the PXELINUX loader you have to define a boot menu entry which looks a lot like this:

MENU LABEL Install Windows…
KERNEL pxeboot.0

To add OpenSuSE to the menu you would add an entry looking like this:

LABEL opensuse
MENU LABEL Install OpenSuSE 11.x
kernel /Linux/opensuse/linux
append initrd=/Linux/opensuse/initrd splash=silent showopts

The paths given in the above entry should be altered according to the paths you’re using in your installation. I took the /Linux/opensuse/ files from the network install dvd images of OpenSuSE.


That’s basically everything there is about the installation of Linux (Debian works accordingly) over PXE and WDS.

And finally this is what it should look like if everything worked great:

sones at CeBIT 2010

Die CeBIT ist um und sones schliesst seinen Auftritt im Rahmen der Partnerschaft mit Microsoft mit einem durch und durch positiven Ergebnis ab.Ich selbst hatte ja aufgrund einer ungünstigen Terminsituation nur am Montag und am Freitag die Möglichkeit persönlich vor Ort zu sein.

Die CeBIT war dieses Jahr eine schöne Möglichkeit einmal im breiteren Rahmen als auf den sonst üblichen Konferenzen und Veranstaltungen zu netzwerken.

sones hatte die Gelegenheit zusammen mit anderen Partnerunternehmen am Microsoft Stand in Halle 4 auszustellen. Geniale Sache war das insofern dass wir sowohl am Stand als auch im Rahmen des MSDN Developer Kinos die Möglichkeit hatten unsere Technologie mit Demonstrationen und Worten vorzustellen.


Ich hatte ja schon darüber geschrieben dass wir eine Demo für die CeBIT auf Basis des Microsoft Surface Multi-Touch Tisches entwickelt haben. Das Feedback zu dieser Demo war durchweg extrem positiv. Es ist eben ein Unterschied für viele nicht-Techniker wenn man Ihnen einen Graph grafisch vor Augen führt und in diesem Graphen navigieren kann.

Für die Techniker auf der anderen Hand hat sich Henning nocheinmal hingesetzt und ein wenig weiter ausgeführt was hinter der Surface Demo steckt. Das kann man hier nachlesen.

Hier ein paar Impressionen:





Developing on a Microsoft Surface Table

At sones I am involved in a project that works with a piece of hardware I wanted to work with for about 3 years now: the Microsoft Surface Table.

I was able to play with some tables every now and then but I never had a “business case” which contained a Surface. Now that case just came to us: sones is at the CeBIT fair this year – we were invited by Microsoft Germany to join them and present our cool technology along with theirs.

Since we already had a graph visualisation tool the idea was to bring that tool to Surface and use the platform specific touch controls and gestures.

the VisualGraph application that gave the initial idea

The good news was that it’s easier than thought to develop an application for Surface and all parties are highly committed to the project. The bad news is that we were short on time right from the start: less than 10 days from concept to live presentation isn’t the definition of “comfortable time schedule”. And since we’re currently in the process of development it’s a continueing race.

Thankfully Microsoft is committed to a degree they even made it possible to have two great Surface and WPF ninjas who enable is to get up to speed with the project (thanks to Frank Fischer, Andrea Kohlbauer-Hug, Rainer Nasch and Denis Bauer, you guys rock!).

a Surface simulator

I was able to convice UID to jump in and contribute their designing and user interface knowledge to our little project (thanks to Franz Koller and Cristian Acevedo).

During the process of development I made some pictures which will be used here and there promoting the demonstration. To give you an idea of the progress we made here’s a before and after picture:

We started with a simple port of VisualGraph to the surface table…

…and had something better working and looking at the end of that day.

I think everyone did a great job so far and will continue to do so – a lot work to be done till CeBIT! :-)
