Develop a variant of quick-sort that uses only one comparison function, say,
<. Its partitioning step divides the given list alon into a list that
contains the items of alon smaller than (first alon) and another one with
those that are not smaller.
Use local to combine the functions int
Facebook might be a necessary evil for advertising, but don't use it
more than necessary.
One of my side projects has involved analyzing Web sites for several
years, and lately there are effective Facebook tracking bugs in the vast
majority of popular Web sites. Which means that Facebook not
It turns out that there's no way to change the name of an existing Facebook
page. I've created the PLT Racket facebook page, and added a note to the PLT
Scheme page directing folks over there instead. All of you admin-y people;
I'll make you admins, but it appears to me that you have to "like"
Hi Sigrid,
I'm revamping Moby; it's being mostly subsumed by my js-vm PLaneT package.
To install, evaluate the following at your DrRacket REPL:
(require (planet dyoo/js-vm:1:2/info))
This will install js-vm and the tools.
Once that's installed, restart DrRacket.
There should now be the fo
We're still having problems with this. It seems to occur randomly,
but I just figured out a way to replicate the behaviour of the server
that maybe you have some comments on. I'm not sure if something like
this is causing the actual problem we're having, but the behaviour
turns out to be exactly

Even with a transparent canvas the problem persists. A transparent canvas just
adds the background color of it's parent to a bitmap you add. So If you were to
put a background image in the canvas that would be fine, but as soon as you
want to add another image to it with transparency, the canvas
Thanks for clearing that up.

Both in the old and new toolboxes, you can make a transparent canvas
using the 'transparent style when you create the `canvas%' object.
If I understand the issue, though, putting a `button%' instance on top

Hi there,
I'm using Racket in a programming language course - more specifically
the PLAI language variant of it.
I'd like to have something like "lhs2tex"

for Racket.
More specifically, I'd like to have my sources in a format that is
executable but can also
