[racket-users] RacketCon hotel discount?

I noticed that the 2015 RacketCon had a "RAC" group code for the hotel. I already booked my hotel, but it's a changeable/cancelable reservation, so is there going to be a group discount for the hotel for this year's conference also? If so, what is it, and when is it active? Brian -- You

[racket-users] Anyone attending RacketCon but *not* Strange Loop ?

Just out of curiosity, is anyone attending RacketCon, but not attending Strange Loop? I'm probably in the minority, but there don't seem to be enough compelling sessions this year for me (although I'd love to hear Matthew's and Andy's talk), so I'm considering flying in for RacketCon only.

Re: [racket-users] Transforming data for plot / discreet-histogram

For now, you can use sequence-map to turn the hashtable into a sequence of vectors. #lang racket (require math) (require plot) (discrete-histogram (sequence-map vector (in-hash (samples->hash '(1 2 3 4 4) But it would be nicer if discrete-histogram took a hash as input. On Tue, Jun 7,

Re: [racket-users] define-serializable-cstruct with versions?

Sorry --- reading through your message one more time, I think I understand what you're saying. My example involved pointers to structures, and you're noting that *inlined* structures create a problem. One possibility is to treat a change to `_pond` as a change to `_forest`, too, and introduce a

Re: [racket-users] define-serializable-cstruct with versions?

I think all this works ok. I've enclosed an example interaction from the docs, which I've just extended to evolve `fish` in addition to `aq`. So, it's all implemented, and I can push if it seems like an ok interface... At Tue, 7 Jun 2016 17:14:54 +0200, Berthold Bäuml wrote: > Sorry, I did not

Re: [racket-users] define-serializable-cstruct with versions?

Sorry, I did not think this through completely. Serialization of cstructs, as it is currently implemented, loses all “sub-structure” for non-pointer content, correct? But wouldn’t because of this lost sub-structure your alternative compatibility protocol also fail when it comes to

[racket-users] Transforming data for plot / discreet-histogram

Hello, Something like the following would be ideal to build a histogram from a sequence of values read in via CSV #lang racket (require math) (require plot) (discrete-histogram (samples->hash '(1 2 3 4 4))) However discreet histogram takes a list of vectors. Is there a way to achieve

Re: [racket-users] Proper handling for a custom current-read-interaction?

The intention here is that you should have a notion of an expression that is itself consistent and you should read until you get a whole one of those and then just return that. The different behavior you see in DrRacket and at the terminal window prompt will, yes, cause different behavior, but it
