I am exploring macros and am trying to define a variable at the top level
(with the goal in mind to dynamically define a group of functions from a
macro).

Hi All,
I am trying to open windoes explorer from Racket using the following -
(system* "cmd" "start" "explorer.exe")
However it is not working and #f is being returned. This works fine from Go
and even VBScript!
Anyone know what I am missing?
Kind regards,

Hello,
I am using the URL library to interact with a REST API.
One of the Endpoints sends returns no content for a POST request with a status
code of 204 (a little unusual however it is an external API so we have to cater
to it).
I can check the status code for 204 and only apply string->port
Hi Tim,
This is great, the whole proxy thing has been an issue for me as well - I took
a stab at doing something like this last year but couldn't get it working.
I have access to a trend and scansafe proxy so can physically test against
those if you want.
Kind regards,

Hi all,
There have been multiple queries about utilising multiple cores with Racket's

Has anyone had any experience using web-server/template?
If so do you have any suggestions on how to best/compose so there is a base

Hi Tim,
The net/http-client library (last time I looked) does not currently support SSL
tunneling which would be required for ssl connections through a proxy such as
squid.
net/url builds on net/http-client and also does not have that support.
Link to what Squid has to say about tunneling -

Hello,
I am interested in the racket web server for some micro services. Just
wondering if by default it runs across multiple cores or if it is
restricted to one due to threads in racket.

Hello,
I am looking at the exercise from htdp 1e on building the tabulate
function from build-list.
Would I be on the right track that I need to create a function to
reverse the result of (build-list (+ n 1) f) to do this?
the function this is to emulate -
;; tabulate : (x -> y) x -> (listof y
Thanks Matthias for yet again looking at my attempt at this exercise!
Agreed Stephen, yes the purpose statement is not as clear as it could be.
Great list, great book, great software.
