Should keep her going until she learns, C or python or ruby or java or whatever.

Agreed, i installed Unbuntu just over three years ago after Dad got pissed of how his new fast computer run about the same speed as his old machine, i explained that the bottle neck was windows and all the services, including secret services, anti virus. The startup from a cold start to desktop and all services loaded was just a joke beyond making a cup of coffee, more like time to actually start growing the coffee beans.

I installed Ubuntu explained how it all came about Debian free/open source FSS and Mum really understood this and especially liked the idea of people sharing there ideas code (sweets/toys) with others.

They love Ubuntu and would not have it another way, Dad is pleased as he does not have to pay for antivirus (antiscam) support.
Mums bashing is also coming along, and she wonders why Ubuntu does not push more upstream watch out shuttleworth she might track you down like a naughty little boy and bash you up a bit if your upstream polices do not change.
