program below does direct browser to the site requested but at same time also

How can I work around this error ? Used this with chrome as default browser.
Is there a way to select different browsers without having to change default
browser setting?

Apologies, I see the problem now. I missed where it says in the
documentation for dynamic-places.
The module-path argument must not be a module path of the form (quote sym)
unless the module is predefined (see module-predefined?).

I think that error is for the situation where you write:
(dynamic-place ''temp2 'place-main)
You need the first quote to be quoted require spec and the second quote
because the module's name itself has a quote in it.
As to your original problem, I think you can use `submod' in the require
spec
Hi everyone,
I coded up a quick-and-dirty implementation of an LRU cache with Typed
Racket to make sure I understood the concept. I was wondering if
anyone can take a look and see if it looks ok?

The implemetation is in 'lru.rkt', and test cases are in

Hello,
suppose I want to format a real number, with a fixed number of digits
after the comma, rigth-padded in a given width, and I want the sign to
be attached to the digits (i.e. not what ~r does).
This is the usual way of printing reals in a table, and can be done
trivially using standard
Does real-decimal-string do what you want?

yes, except for the width. It can substitute the ~r in

but not the ~a.
Srfi/48 still wins in convenience and
Why cannot that contract be checked? It seems that since the or/c is
the unwrapping of the parametric contracts it should be possible,
since the first order checks should differentiate them.
