It's pretty much all in the title: what library would you recommend to perform principal component analysis? I'm looking for free and simple to use - performance is not necessarily a criterion so far as I just want to play around with the concept and see what I get. Google got me this:
http://crsouza.blogspot.com/2009/09/principal-component-analysis-in-c.html
Anyone tried this? How good is it? Would you have any other recommendation?

I have used PCA in SPSS and Matlab. This is a good place to start learning it, as those applications have already got all the infrastructure ready for you (like lots of plots and supportive tests).
If you are looking for something in C#, take a look at the Accord framework and maybe this sample here

Thanks for the help guys. I eventually decided to implement the algorithm myself, using Math.Net Numerics to lay the matrix groundwork and ARPACK to do the hard work of finding the biggest eigenvectors of the correlation matrix (I don't need of all them). Subject closed.

I am a long time experienced Windows Forms developer, but now it's time to move to WPF because a new WPF project is comming soon to me and I have only a short lead time to prepare myself to learn WPF.
What is the best way for a experienced Winforms devleoper?
Can you give me some hints and recommendations to learn WPF in a very short time!
Are there simple sample WPF solutions and short (video) tutorials? Which books do you recommend? Is www.windowsclient.net a good starting point? Are there alternatives to the official Microsoft site?
Thanks in advance for your help!

I like this tutorial:
http://reedcopsey.com/series/windows-forms-to-mvvm/
Also, dont be afraid about forgeting what you learned. WPF was designed as totaly different technology than WinForms. So in some aspects it results in completly different techniques to reach your goal.

A really well done book is http://www.amazon.com/WPF-4-Unleashed-ebook/dp/B003UBAYXE

There has been much debate on Charles Petzold's book "Applications = code + markup" but I still value it.

Can you recommend a single downloadable video (one that you have actually watched and that you think is of high quality) introducing LINQ (not to be
confused with "LINQ to SQL") to a somewhat experienced VB.NET/C# developer?
It could be a screen-cast showing real code.
"Downloadable" includes YouTube and ShowMeDo (Flash video)
as there are ways to do this. A streaming-only video is not
acceptable.

Check out LINQ Videos (www.asp.net).

There is a few on dimecasts

I found the Tekpub Mastering Linq series quite nice. It does cost a few bucks, but it's quite in depth.

Anders Hejlsberg gave a couple great introductory talks about LINQ at the Lang.NET Symposium in 2006 and 2008.

http://www.learnvisualstudio.net/
He has LINQ tutorials. His tutorials are great. I was a member for a year. It's $60 a year.

My working environment is VSTS 2008 + C# + .Net 3.5. I want to learn the differences between UI thread and worker thread, and any other types of thread (i.e. non-UI thread is the same as worker thread)? I also want to learn the restrictions of what we can do on each type of threads and best practices to avoid any issues.
Appreciate any good tutorials! :-)

There's a long, detailed tutorial on threading here.
Specifically, I'd recommend this section on worker and UI threads and how they can interact (it does assume you've read the previous chapters though).

This site has great threading details covering: Getting Started, Basic Synchronization, Using Threads, and Advanced Topics.

I'm looking for open source applications, built with winforms in C#. Specifically, i'm looking for applications using new and real world techniques. Like nerddinner and oxite for asp.net.
Thanks

SharpDevelop is an excellent example IMO
Another one was Paint.net, but it's no longer open source, see comments.

Look to codeplex, SourceForge and Code Google. There is lot of applications :)
Next resource is CodeProject.
Paint.Net is nice example.
Here is source code.

NUnit is a good "real world" open source application...
