Finally a working gtalk voip in linux !!!!!

I have been browsing through net and came across this post
http://alex.eftimie.ro/2008/11/18/howto-gmail-voice-and-video-chat-on-ubuntu-linux/
I have tried jabber and other gtalk voip clients for linux that are said to be working , and nothing actually worked for me. I was bored and thought i would give the above method a shot (thinking that it would end the same as before). Surprisingly it worked :), for the first time i was able to call a gtalk user and do voice chat from linux :) althought video doesn't work.
However im still using pidgin and occationally switch when voip is necessary. And i already gave up on google to release gtalk linux native.

Opencv on Beagleaboard !

I tested opencv on beagleboard for onboard image processing. The examples provides with opencv runs fine , but the performance is poor compared to a PC.

BeagleBoard (OMAP 3530, ARM Cortex-A8 600MHz, 128MB ram)
PC (Intel core2duo 2.13GHz, 1GB ram)

It took me about 4.4 sec on beagle for a simple facedetect example to detect all faces and around 0.35 sec on PC
