Neither do I, whats your point?

theory is followed by code snippets to make the concepts clear.maybe you did not get it.please make your critic constructive by pointing out specific things to talk about and don't just say things just to say them

I got it, but no, I won't get more specific, I'm not interested in writing another essay.

Oh, and btw, Shama Lama Ding Dong.

I play no expert or the smarty one.I just display my findings after I have done my research.I don't have a particular target group

That is your problem. You keep it superficial, because you already know all the ins/outs. Why do you think an article written for yourself would be interesting reading to others? You have to pick an audience, and write specifically for them.

A bibliography wouldn't hurt either.

Mike James who has been on the scene for a couple of decades, runs the site and VSJ magazine and has a couple of PhD's thinks that the article is very good.But you seem more qualified to judge since you have a degree in Astrophysics, work for NASA and have send a bot to Mars :-) And as you seem to know what an expert would think, this automatically upgrades to you an expert and since you surely know all the things that are demonstrated in the article, after you complete your expert ,I am certain, research, please let me know of it. i will be glad to take a look at it thanks for your opinion anyway

Maybe you've heard of me, I'm Donald Knuth
