The article doesn't even argue that it's a race thing, it simply starts with the premise but explains it as socioeconomic. I agree with the article on that one. I am not white and I was never discouraged in any way from programming because of my skin color or ethnic background (I've been doing it in some form since I was 6 in the late 80s with full support from pretty much everyone, including a lot of monetary support from my upper middle class parents).

edit: it actually does get into race, but around blacks/african americans. But it didn't get into Asians - my point really is this isn't a white thing per se.
