Jukka, this all sounds like an inspiring idea, kind of like a return to the
future of Lisp machines.
1. What kind of uses do you imagine?
2. I am not sure how the phrase 'network OS' connects to the rest of the

limitations related to which language (Beginner, Advanced, full Racket...)

Well I believe that abort actualy aborts so that requires some
interesting work.

Hi all,
after about a decade's development work, we (Finndesign) are about to
release something that we feel very exited about. It's a network OS called
Liitin and it uses Scheme (Racket) as built-in language. BTW, Liitin means
'connector' in Finnish and is pronounced like "Lee tin".
Rational:

I have DrRacket setup to determine language from source and I add the
following to the top of the original WeScheme program, which gets it
to run from DrRacket:

(require 2htdp/universe)
(require 2htdp/image)
When I run the following to try to build an Android phone app:

So having separate implementations is for optimization?

Start reading HtDP/2e @ http://www.ccs.neu.edu/home/matthias/HtDP2e/
It uses strings, which may be more familiar to you and which accommodate a bit
more variety.
Then switch back to HtDP/1e.

Hi again,
I'm not sure where to ask this question, but
why are 'raise' and 'abort' implemented separately
(rather than, say, 'raise' by means of 'abort')?
I haven't understood the implementations of these primitives,
but they appear very different (in error.c and fun.c).
Will someone explain to m

Thanks so much for those valuable suggests you gave. I've been reading

that website.

AFAIK AAMAS is the main conference, but I'm not in the field:

If you wanted to build a new mobile agents framework for research
purposes, I think that using Racket would be viable.
Some relevant features that Racket gives you atop what typical Scheme
dialects/derivatives do include: greater ability to limit resources, the
serializable continuations work
