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.

the process of taking the images

after the pictures are taken additional stitching is needed

after the stitching completed a fairly impressive panoramic images is the result

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! 🙂

How to shut off Outlook 2007 Security Questions

I had the task to make my Outlook Task List appear on my iPhone. As everyone knows Apple did not do anything about todo lists or tasks on their phone… well there’s an app for that: Most of the task applications on the iPhone use Toodledos services to sync task lists with the desktop.

To sync the Toodledo service with the desktop you need another tool. This tool uses your Toodledo account and your locally running Outlook to sync between both. So this little desktop sync tool needs access to the Outlook data: This means you will maybe be bugged by Outlook that some program wants to have access to the data. You can allow it for a number of minutes but not forever.

Okay one solution would be to install appropriate antivirus tools to suit the operating systems security needs. Because this wasn’t a solution in my case I needed something more sophisticated to solve the problem.

Now that’s the point where “Advanced Security for Outlook” from MapiLab comes into play. This Outlook Plugin extends Outlooks Security Dialog and adds things like “always allow”:

Killer .NET 4 feature: Memory Mapped files

“So what is it? A memory mapped file allows you to reserve a region of address space and commit physical storage to a region (hmmm, sounds like virtual memory, isn’t it?) but the main difference is that the physical storage comes from a file that is already on the disk instead of the memory manager. I will say that it has two main purposes:

  • It is ideal to access a data file on disk without performing file I/O operations and from buffering the file’s content. This works great when you deal with large data files.
  • You can use memory mapped files to allow multiple processes running on the same machine to share data with each other.“

OMG! You can even specifiy views on a memory mapped file… from different processes… .NET 4 FTW!

the .NET Framework sourcecode release and how to unpack it…

It’s great to finally have the .NET sourcecode for debugging purposes – inconveniently it’s in a format you might have your difficulties just browsing along. A little tool is here to help!

After you installed, let’s say the WCF sourcecode and debug symbols you get a directory structure similar to this:


This file holds the whole sourcecode as one big package. It can’t be unpacked – even one would suggest that by just looking at that .zip ending in the name of the file.

Instead this is a plain-text file of a certain yet simple format. I wrote me a little tool to unpack this file into it’s original files and directories.

You can get the little tool, including sourcecode, here:

To start the magic, you would like to go to the command line and start the tool with two parameters. Parameter 1 is the path and filename of the file. Parameter 2 is the part of the Path that needs to be cut-off. For the WCF Sources it’s “/DEVDIV/depot/DevDiv/releases/Orcas/SP/ndp/cdf/src/” for example.

The tool will then start to whirl through the file and extract all the files it founds into directories it’s creating along the way. After some seconds you would end with a directory tree like this:


Have fun!

DPM 2007 problem – why can’t I install the Remote Agent?

I tried to install a Data Protection Manager 2007 Remote Agent remotely and on the machine locally. Trying to install it remotely will always fail with this error message:



Since “tfs” is the only x86 server we have and everything else including the DPM 2007 Server is x64 this is my only bet – but so far even the local installation (which worked) did not change anything. I installed the remote agent and did the console setup setting the dpm server. I then added the production server to the DPM 2007. But the error message remained. I just don’t know what else to do.

freebie day? Another Vista Ultimate game is available…

It seems that today it’s the freebie day (well… for some of us). Because today the next Windows Vista Ultimate Extra is available: Tinker.

Tinker – to shorten up things – is a Sokoban interpretation with some interesting twists.


“Being a small robot isn’t always easy. Being a small robot marooned in a surreal world of clockwork, obscure mechanisms and infuriating puzzles, even less so. In Tinker, a puzzle game that pushes the boundaries of robot frustration, you’ll guide your robot through switches, lasers, teleporters, and a host of other contraptions to reach the exit. He’ll only do what you command. He’ll only go where you tell him to. Will you lead him home, or will you doom him to eternal confusion?

Featuring captivating visuals, an original music score, and 60 levels that range from the facile to the infuriating, Tinker is an isometric, two-dimensional puzzler published exclusively as an Ultimate Extra for Windows Vista Ultimate Users. Tinker features tutorial level, and will include regularly released level packs to expand the experience. Want even more? Download the level builder, and create masterworks of ingenuity to keep your friends scratching their heads. What are you waiting for? Start Tinkering.”


It’s good looking, fun, the music is great and it’s free…

create panoramic images with a free tool

There was the Digital Image Suite and several other tools like Hugin and Cool360 which I used over the last years to create panoramic images. Now there’s a new tool available in 32 and 64 bit (for really really huge images!) from Microsoft Research. It’s free at this point and if you’re on Windows it’s definitely worth the try.


“Microsoft Image Composite Editor is an advanced panoramic image stitcher. You shoot a set of overlapping photographs of a scene from a single location, and Image Composite Editor creates a high-resolution panorama incorporating all your images at full resolution. Then save your stitched panorama in a wide variety of formats, from common formats like JPEG and TIFF to multi-resolution tiled formats like HD View and Silverlight Deep Zoom.”

how to create your own photosynth

Photosynth is publicly available and it’s time to give it a try and play with the technology. Before starting you should be aware of some facts about the public photosynth technology-preview:

  1. all synths are uploaded and only available online (broadband needed)
  2. all synths are public, everyone can access them
  3. the synther tool runs only on Windows
  4. you’ll need a Live ID

When everything is checked you can go and upload up to 20 Gbytes of image data – my test synth takes up 200 Mbytes of the available space – so you have plenty of space to play with.

To start just install the photosynth application to view – and click “create” on the website. After the obligatory login you immediately can upload your pictures. Give it a name, ssome tags and a license and select your pictures.


Your pictures should show the same scene from different perspectives – photosynth is all about matching perspectives. After clicking on “Synth” the process starts.


And after a surprisingly short period of time your synth is done. Click on “View Synth” and you’re taken back to the website and you can browse your synth. That’s it – easy!

So writing a filesystem in .NET isn’t a bad idea after all :-)

Ever since we started writing a complete and cutting edge filesystem in C# and only managed code we are confronted with questions like

“Why C#? Why .NET? Why not in a more low-level language? Why a filesystem after all?”

I don’t want to talk just yet about our reasons but we can’t be that wrong if even Microsoft Research is trying to get their .NET Operating System research project Singularity ready for customers:

“Midori is an offshoot of Microsoft Research’s Singularity operating system, the tools and libraries of which are completely managed code. Midori is designed to run directly on native hardware (x86, x64 and ARM), be hosted on the Windows Hyper-V hypervisor, or even be hosted by a Windows process.”

This would be an Operating System 100% in managed code – hey Microsoft – maybe you want to talk with us about our 100% managed code filesystem?! 🙂

To prevent rumors: no – we are not working on anything Microsoft related, yet.

Graph theory: How to visualize a network

Since I am a bit familiar with graph theory and building technologies around graphs I came across this neat little library originally developed by Marc Smiths Team at Microsoft Research. It’s now up on Codeplex for your own study and research:

“.NetMap is a pair of applications for viewing network graphs, along with a set of .NET Framework 2.0 class libraries that can be used to add network graphs to custom applications.

A network graph is a series of vertices (sometimes called nodes) connected by edges. See this Wikipedia article for an overview of network graphs.”

Graph6 Graph1


It even integrates into Excel…well if you need that… more interesting is:

“The Windows Forms control is one of several graph “visualizers” that are packaged in a Microsoft.NetMap.Visualization assembly. There is also a Microsoft.NetMap.Adapters assembly for reading and writing graph data in various formats, a Microsoft.SocialNetworkLib assembly for analyzing social networks, and a Microsoft.NetMap.Core assembly that implements the low-level vertex, edge, and graph classes. The framework for a Microsoft.NetMap.Algorithms assembly is also provided, although most of the graph algorithms are still work items as of May 2008.”

a tool to convert a Windows Server 2008 machine into a useable workstation without loosing anything

I cannot talk about the “more stable”-part since my Vista machines do not crash but if you’re one of those who just cannot live without the newest cutting-edge kernel version go ahead install Server 2008 and convert it into a useable workstation with Sound and stuff 🙂

Hyper-V vs. Virtual Sever 2005 R2 – a “benchmark” using Sharepoint

Michael O’Donovan has a great benchmark-comparison of the brand new Hyper-V and the older Virtual Server 2005 R2:

“I have done a fair amount of SharePoint demos and developement over the past few years, and have always done this on my laptop using Microsoft Virtual Server 2005 or Microsoft Virtual PC, to host and run a SharePoint environment. Last year at Tech-Ed, while I was doing a demo, I had a comment from someone in the audience “Why is SharePoint so slow?” To some degree it makes sense, the specific SharePoint virtual environment which I was using at the time had almost every product known to man installed (the virtual hard drive size was 40GB), as well as being a domain controller and running on a laptop which only had 1GB ram assigned to the virtual machine. However, with the RTM release of Hyper-V (on Windows Server 2008), I wanted to see if performance was better now.”

One graph from his article:


Guess now – which color is which product?

Meet the C# 4.0 design team…

Channel 9 has the bits and pieces:

“What’s the C# team up to these days? Who’s on the C# 4.0 design team, anyway? With the looming problem of manycore facing developers now and certainly in the near future (to a much greater extent – programming for 80 core (asymmetric to boot) processors, anyone?). I thought it was time to find out what Anders et al are working on to get a clear sense of C#’s near (and not-so-near) future so I asked if I could come to one of their design meetings to have an informal chat (are we ever formal on C9?) and meet the people behind the next iteration of the most popular .NET programming language.”
