Will give one dollar

Somebody help me.

I need to know what the fuck the rtb and rff filetypes are in relation to software development. I tried googling but it didn't help.

This is for an interview for a position in which I will be using these file types.

Will give on dollar in the form of a money order, cash, or paypal.

SICP is not about Scheme. You don't understand what's the purpose of SICP. Whatever you said after that is now invalid, I didn't even bother to read it.
