Re: [racket-users] Re: Error when I try to use slideshow?

Thanks! After running System Update, I'm able to see the failure, too. It looks like the problem is that the main bitmap given to `CreateIconIndirect` is scaled, but the mask bitmap is not scaled (in `bitmap->hbitmap`). So, replicating the error also requires a high-resolution screen with scaling

I forgot to CC my reply to the list. The case here is that the user account data in `users.rktd` only contain one field but the default `extra-fields` configuration requires 3 extra fields. The error message probably comes from some (map cons ...) expression that resides in the server code.

You're omitting some key facts. So no, I don't agree with your legal analysis. But the underlying point remains: there is unnecessary murkiness around Racket's licensing status. > On 23 Aug 19, at 11:24 AM, Alexis King wrote: > > AFAIK, copyright of the Racket codebase is not the Racket

Re: [racket-users] Is it possible to sell commercial use rights to an open source Racket package?

First, thank you all for the responses. Originally I figured I would need to find some key contacts and ask them to review my Racket package* for written permission to publish under a proposed license. But if ownership itself is a question mark, I wonder if I should just pick LGPL for safety

Re: [racket-users] [racket ursers] Keyword question

If they do what you want, `curry` and `curryr` support keyword arguments (as of Racket 7.1) and handle lots of cases. If you do need to use `make-keyword-procedure`, you may want to combine it with `procedure-reduce-keyword-arity-mask`. -Philip On Fri, Aug 23, 2019 at 10:03 PM David Storrs

Re: [racket-users] Is it possible to sell commercial use rights to an open source Racket package?

(Replying to 2 messages...) Summary: I think there's probably no barrier for you with Racket's licensing and intentions, but you will need to talk with your lawyer about the unusual licensing you want to do for your own software. Also, a few related thoughts. Sage Gerard wrote on 8/23/19
