I'm wondering how much it would take to get frame-by-frame output from a
webcam using Racket. My desultory searching hasn't turned anything up, so
I'm hoping someone has a hint or two. This wouldn't involve any networking
or remote access, but I would like to be able to acquire a stream of frames

I just saw the string Alexandre Moreira started a few days ago. No need to
repeat anything from there. I guess it's just worth noting that he isn't
the only one that wants to (read-line) from a function invoked on the REPL.
My use case is similar to his. I have functions that take several

Hi All.
I'm having an issue with (read-line). Below is some output from running the
attached rkt file on my system(Ubuntu 10.10, Racket 5.0.2). In the first
instance the script runs, and as I expect I can enter a string such as
"Hello". When I use the repl it does not work like I expect it to, a

Racket is the first time I've used a system with GC and been able to
see stats for it like this. As a result, maybe this is a dumb question
and the answer is obvious to the rest of you, but:
What does it mean for the GC to collect a negative number of bytes?
My (naive?) mental model is that the G

A servlet for the PLaneT site seems broken, and I think that a use of
Scribble "seclink" in a PLaneT package might be breaking both this and
my local documentation cache.
The documentation for a PLaneT package contains a link to a manual, like:

Thanks for the pointer. I had hoped to avoid making two passes with
different readers.
Can anyone give me a hint? It looks like the pieces are there, but
there are no examples in the documentation that explain how to get at
the pieces I need and how to plug them in.

I like it!
It would be nice to have automatic indentation for the at syntax. Also,
it would probably be convienient if the installation script associated

After a few minutes trying it, I like it a lot.
A few suggestions if I may:
- Every @something could be in a different font? (if you can scan
definitions and requires, that's even better, but I don't expect that)
- It would be nice if you could add the
@;{
blah blah
blah blah
;}
comment style.
- C
Worked for me too. Thanks a lot, that is very handy!

Hi Noel,
I think different people would benefit from Liitin differently, or in a
different phase of life.
I could try to guess some features that you might find interesting. Let's
suppose your username (=namespace) would be nwe100.

At last, a legitimate use for the fact that a PLaneT "require" alone can
execute arbitrary code. :)
In case anyone is wondering, that "require" form will of course make
sure that the PLaneT package is installed, and then it will go and try
to find your Emacs initialization file and add/update
Not brave but reckless. Worked for me.
