Hi, not sure if this is considered a bug?
(send model save-file model1.bmp 'bmp)
save-file in bitmap%: kind saving not yet implemented: 'bmp
I found this link, and it's been 2 years since. Is it an update that will take
a long time?
Hi,
Thanks for your answer. I meant the former, i.e., a 2D pict of a ball with
some shading to make it look 3D.
Is there any quick way to do it or I have to implement the algorithm by
myself?
Thanks again.

That was a bug in the revised implementation of `define-generics` for
the new expander. I've pushed a repair.

Hi all,
I'm found something strange with Racket 6.1.1 and Postgresql (9.3.6):
SQL that works differently in a Racket query than in the DB console.
I have a table defined as
create table blah
(
a char(15),
b char(15),
created timestamp with time zone,
I don't really know what's going on, but this might help:

Hello,
I'm trying to update some code to the new expander. The below code works on
6.2 but fails on the new expander with an unbound identifier error.

(require (for-syntax syntax/parse))
;; a standard context for identifiers
(define-for-syntax ctx #'ctx)
;; create an ID with the
Sorry for the delay. It has been a very interesting week in the low
level implementation of Racket. A few days ago, Matthew fixed the bug
and enabled the new expander, and then he fixed most of the problems
that appear with the changes. So now looks like a good time to retry
all the tests and see
You might be ending up with different timezones set on the different
connections, as libpq clients can automatically set/change some
session settings that the racket library does not. I'd try running
show timezone via both connections, and see what you end up with.

The new expander treats submodules like everything else. Since
`racket/math`, is macro-introduced while the body of the submodule `pi`
is not, the import doesn't bind `pi`. For that matter, the initial
`racket/base` import is also macro-introduced and doesn't bind `#%top`
for `pi`.
OK, this

I'm trying to create a way to automatically turn test cases into examples. I'd
like a macro that turns this:
(extract-expressions
(module+ test
(check-equal? (extract-expression (square 5)) 25)
(check-equal? (extract-expression (square -5)) 25))
(module+ doc
