I had a pretty simple requirement in my Scheme program to execute more
than one statement, in the true condition of a 'if'. . So I write my
code, something like this:

executed when the condition is true
(expression3)…

Hi,
I'm a beginning student in CS, and my classes are mostly in Java. I'm currently going through "Little Schemer" as a self study, and in the process of finding out how to do that I have found numerous references to "implementations" of Scheme. My question is, what are implementations?
Are they…

Isn't it possible to treat functions in Scheme as any other list?
Basically, what I want do to is something like this:
(define (foo) "hello")
(cdr foo) ; or similar, should return the list ((foo) "hello")
I've found a similar discussion about this, and I feel a bit disappointed if this is not…

Hi
I'm quite new to Linux, but before using it I was hearing that Windows programs, after uninstallation, leaves a lot of remains on the hard disc, and Linux removes all.
I'm using Ubuntu 10.04. To uninstall packages I'm using sudo apt-get autoremove application_name or sudo aptitude purge application_name…

If a remote user already exists locally, update its fields.
If a remote user doesn't already exist locally, add the user.
If a local user doesn't appear in the remote list, deactivate…
