I am looking for a way to start detecting faces in an image.
Any recourses that you use or find best for beginners?
Thanks.
Generally there are at least two approaches.
Finding a face based on the color (e.g face color and hair color)
Based on characteristics of the face (we have two eyes, and a nose below etc.)
Try this page that describes basic techniques of face detection

I was asked this during an interview, and I wasn't able to come up with an answer.
The idea is to write a program using only the C standard library, and find out how many CPU cores the box has. The solution needs to be platform independent, and using external libraries or system calls is not allowed.
Does anybody have experience with this? Thanks!
Thanks everyone who participated. I think now it seems like the answer will be "there's no reliable way of doing this." Great discussions guys!

I was wondering how to create a scroll that looks something similar to this:
I'm really interested on being able to build one like this, and I'm not sure on what elemnt is this one and how to implement it. I've been searching, but I can't find any information... So any tutorial, guide or clue will be really appreciated.
Take a look at "A Knob Slider Control". It doesn't look as nice as your example, but that's just a matter of styling. Maybe you could use it as a starting point?
See the tutorial of Charles Petzold. It gives a nice introduction how to create curved sliders and scrollbars.

I'm looking for Xlib function or macro that will give me actual screen's refresh rate. Thanks.
Doing a quick search tells me it's not possible directly with xlib. However it seems possible using the XRandR extension, with the function XRRConfigRates.

Looking for embedded C projects where I can work with group or individuals. My goal is to keep skills current while honing and learning new skills and techniques.
You could try using Arduino, it seems to have a big community worldwide.

Does anyone know of a list of C programs that can be practised by beginners?
Hi you can use something from here http://www.simonhuggins.com/courses/cbasics/index.htm
but i can recomend you this book http://www.computersciencelab.com/Deitel.htm there are lot of samples
Sphere Online Judge has a ton of problems at many difficulty levels. The neat thing is you can submit them after you're done to have the server run the program and tell you if you got the right results or not.
