Bug in OpenCV

I wanted to capture an image from the web cam and convert that to gray scale in my application. I use openCV to do that. But when I directly convert the captured image to gray scale it returned a horizontally flip gray image of the original. but if I load an image using cvLoadImage() and then convert it to gray scale there was no problem. No flipping is involved. I think this was a bug in openCV. Correct me if I am wrong.

here is the code that cause the flipping,

CvCapture* capture = cvCaptureFromCAM( CV_CAP_ANY );
IplImage* frame = cvQueryFrame( capture );

IplImage* gray = cvCreateImage( cvGetSize(frame), 8, 1 );
cvCvtColor( frame, gray, CV_BGR2GRAY );

Einstein's Challenge

Would you like some brainstorming challenge. Here it is. It is often called "Einstein's Puzzle" or "Einstein's Riddle" because it is said to have been invented by Albert Einstein as a boy. Some claim that Einstein said "only 2 percent of the world's population can solve it". But I believe it should be more than 2% if they given sufficient time. so here it is, ENJOY !!!!!!!!!!!!!!!

There are 5 houses in 5 different colors. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.

• The British lives in the red house.
• The Swedish keeps dogs as pets.
• The Danish drinks tea.
• The green house is on the left of the white house.
• The green homeowner drinks coffee.
• The person who smokes Pall Mall rears birds.
• The owner of the yellow house smokes Dunhill.

Inter department tournament

Today we have participated to our inter department cricket tournament. As we are now in our final year this is the last tournament we are competing in the university. Though our team couldn't make it to the finals, it's a great pleasure to took part in such an event as all the batch mates from different departments had the opportunity have a good time with their friends from other departments. Department of Civil Engineering won the trophy and Department of Mechanical engineering was the runners up.

Erlang Rocks

Erlang is a general-purpose concurrent programming language. It was designed by Ericsson to support distributed, fault-tolerant, soft-real-time, non-stop applications. It supports hot swapping so code can be changed without stopping a system. One of the main reasons for using Erlang instead of other functional languages is Erlang's ability to handle concurrency and distributed programming. So why don't you try this. believe me you'll love it .
