You can also edit your racket-prefs.rktd file in your `(find-system-dir
'home-dir)' directory if you just want to empty the history.
Be careful not to break anything though.

Let me respond to your argument with a specific question.
Below is some code that sets up fluid-like dynamic variable bindings using Jay's

In the "Preferences" dialog, there is a "General" tab with a slider
control that allows you to set the number of recent items displayed.

Dear list members,
Is it possible to prune the DrRacket "open recent" files list.
Thanks,

Historical info and a concern...
There used to be a Scheme Cookbook wiki, which was an effort to build
something like a Perl cookbook of the time.
It was a good idea in principle, but two of the problems were:

This thread raises an interesting point.
An Artifact is herein defined as some piece of Racket code that does a useful
piece of work.
Some of the lesser lights in the community, (such as myself) will, over the
course of a working day, come up with a useful Artifact or two.

Wow. Thank you very much.

Calling these tools can be a little more complicated.
I'd put those port close calls in a "dynamic-wind" cleanup thunk. I'd
also catch the exceptions that could be raised by the port-closing
procedure itself in the cleanup thunk. And I'd make sure that any
custodian I was using didn't close

Yes. Absolutely correct. I should have done this.
Please include the following three lines to close the three ports

One comment here: you really want to be sure that you close all three
of the ports that process returns, or else you'll run into problems if
you use this in a larger context.

Neil V. mentioned his preference for directly calling the OpenSSL

I wanted to provide a small example using this technique for

Ok, thank you all for the input, however I'm still missing an important detail.
So I build a suffix tree, but how exactly do I refer to the target documents?
Should I tie a reference to each document in which the string occurs
to each node? I can't think of other way to do it.
