My ex-professor, who is currently pursuing Phd in computer networks at University of Cincinnati, OH, USA once wrote me the following testimonial; "A Gadget and a tech freak, who can converse with me on the same wavelengths and understand what I have to say. quite a feat. that, because not many people can." I'm currently doing Masters in Telecommunications Engineering at UNSW. I don't charge anything if the problem is unsolved.
