<p>annasdad,
"What was that about credibility? " - No credibility, just simpleton Computer Programmer for about 30 years now and still enjoying it. I never claimed to be any Scientist, I used to be an EE, but I never liked it.
As I have no credibility, I am just sorry for having been giving advice to anybody inquiring about CS. I just know that Computer Programming is a very exciting job, I do not know anything about Computer Science jobs, I have not seen advertisement for one as many as I have seen while looking for my 9 jobs and going thru numerous interviews in my 30 years of writing computer programs. My guess is that they do not exist in my region. Maybe on coasts.</p>
