12:11 Lucas: do you know much about racket language?
12:11 Lucas: Im in need of critical help
12:11 Araq: nope ;-)
12:12 Lucas: =/
12:12 Araq: just ask
12:12 Lucas: 1. Write a function, fx, that takes as input a number, x, and that returns the value of f(x) = 3x^2 + 31x + 8 .
12:12 Lucas: do you know this?
12:14 Araq: sorry, no
12:15 Araq: (defun f(x)  (+ 8 (* 31 x) (* (^ x 2) 3) ))

12:30 Lucas: It is a pop quiz I was not ready for.
12:30 acarrico: Then you had better talk to your teacher and get caught up.
12:30 Lucas: I want to pass this and catch up to the material.
12:30 Lucas: This is why I ask for help.
12:30 acarrico: You are asking for answers to a pop quiz on the Internet?
12:31 Lucas: I know I can learn this for next lesson, but at the moment I dont have the resources.
12:31 Lucas: Pretty much.
12:31 acarrico: That is cheating.
12:31 Lucas: I know
12:31 Lucas: Im ashamed
12:31 acarrico: I'd talk to your teacher about getting caught up.
12:31 acarrico: (If I were you).
12:31 Lucas: But more shameful would be handing in a blank paper.
12:32 Lucas: I will, but I dont want to fail this quiz
12:32 acarrico: Asking for help is not shameful. Cheating is shameful.

21:10 rajah: yeah
21:12 rajah: I'm trying to access the (get-pango) function in the font class, accessible methods are defined with def/public but (get-pango) is defined with define/public
21:12 asumu: rajah: def/public is basically the same as define/public.
21:13 asumu: The only difference is that it allows some extra checking of arguments, but you should avoid that anyway if you're writing new code.
21:13 asumu: Instead, use class contracts.
21:13 rajah: why is (get-pango) not available to call then
21:13 asumu: Probably because it's defined using a local member name.
21:14 rajah: Do you know how I would go about getting the glyph data of a font?
21:16 asumu: Yeah, it's because it's a local member definition. See racket/private/draw/local.rkt.
21:16 asumu: You might be able to access the method if you require that file.
21:16 asumu: Err, racket/draw/private/local
