Brain failing

Just happened to wake up today, can't say what day it is.
Assigned work started months ago, can't meet deadlines.
Late in the night, can't sleep any more.

I'll try SICP. Thank you.

Anyway, is it any good to have printed copies of SICP, OnLisp and PCL?

No. Digital formats are superior.

Damn, I am failing bad.
(define (_e a x y)
  (if (= y 0)
      a
      (if (even? y)
          (_e a (* x x) (/ y 2))
          (_e (* a x) x (- y 1)))))
(define (e x y) (_e 1 x y))
(e 3 1000000)
Why do I need to xkill it? ;__;

Forget about it. Tested on cmdline and it worked. ¬¬

BTW, after I finish SICP, which one should I read next? PCL or OnLisp?
