Today, I removed bugs, installed packages, IRC and did image processing functions. Octave-4.0.0 is working great now. To remove the broken packages, I used dpkg -r <package_name>. There was a presentation by Amrit on openCV. It was quite good. He explained many functions like thresholding, resize, blur etc. With the majority of votes, he got entry into the Great Developers Group. After lunch, I restarted my work and tried my hands to make openssh server. Also tried to compile OpenCV but got some issue. Then, spend sometime on reading and when I read I often forget about other things.
