SICP

Hi /prague/
I'm currently reading SICP to learn LISP. The question is, what LISP do I have to install to follow the book ?
Common Lisp ? Scheme ? Another ?

Why bother changing the compiler when you can target the underlying OS and the CPU microcode?

It would be trivial for an adversary to alter both the file, the sig, and the public keys as I retrieved them from a remote host. Besides that, why would I trust PGP? There could be a malformed key that evades detection, or the security could have been cracked but as-yet undeclassified technologies.
