07:52 bremner: eli: good morning
08:00 eli: bremner: Already asked in an email...
08:01 bremner: ok
08:01 bremner: now you know the order I look at things ;)
08:03 eli: bremner: Yeah, not surprising...
08:04 eli: bremner: As long as you're here, I need to apologize for not answering your question about the broken language barfing about taints.
08:05 eli: First, using 5.2 is not a good idea with my language, since I tend to follow new things fast enough, and it rarely fits anything except for the latest version.
08:05 eli: (This is usually because I rely on a bunch of internal TR things.)
08:06 eli: But second, that particular problem is because of some problem with racket/package that should be resolved, but that waits for Matthew...
08:07 bremner: ok. I more less wanted to stick with the same version I started the term with, to avoid problems with students having different versions.
08:07 eli: Yeah, obviously switching mid-semester is a bad idea...
08:07 bremner: probably you started with a pre-release, or debian was a bit behind
08:08 eli: No, I stick to the released versions, and I also try to avoid upgrading mid-semester, except in cases where I need some bug fixed which requires upgrading.
08:09 eli: In rare cases I'll grab a nightly build and have the students use that -- but those are thankfully very rare.
08:09 bremner: eli: anyway, I wanted to tell you I got some positive feedback from students on your language/notes
08:10 eli: For the broken-scope language I had a hack somewhere, making the handin server loose for that.
08:10 eli: But I can't find it now -- maybe it was resolved...
08:10 bremner: It would of course be even nicer if/when plai is updated.
08:10 eli: Ugh, that's another embarrassing thing...
08:10 eli: I really need to start talking about it more seriously...
08:11 eli: In any case, positive feedback is nice to hear, of course, but if there are any issues then I'd love revising it.
08:11 eli: (... love getting feedback so I can revise it.)
08:12 bremner: well, I think I complained as things came up.  Otherwise I had to change things a bit to adapt to lack of racket background
08:12 bremner: mostly I just did less.
08:13 eli: Yeah, that part is probably not going to be in the book, and I expect people to have very different requirements for it.
08:15 bremner: I think the only "philosophical difference" I had was one or two places I chose (e.g. with the Number = Real ) to leave PL closer to typed racket at the possible cost of some other confusion.
08:17 eli: bremner: Yeah, that might change too.  Were there other such issues?
08:19 bremner: hmm. that looks like the only one where my PL dialect diverged. So maybe I'm just imagining a general phenomenon.
08:19 eli: BTW, I thought that you were on the west side, I now see that it's actually on the NE side.
08:20 eli sighs
08:20 bremner: of the continent? Boston is one of the closest "real" cities
08:21 eli: Yeah, and you're in the direction that always tempts me to start driving.
08:21 bremner: well, drop by anytime.
08:21 eli: A few years ago we went on a trip to Newfoundland, which we really liked.
08:22 eli: Mostly because flying over it makes it look so interesting...
08:22 bremner: yeah, it's amazing. Bay of Fundy is pretty cool too.
08:22 eli: I keep dreaming about a long winter trip...
08:22 eli: But that looks extremely expensive.
08:23 eli: (Talking about places where you can only fly around.)
08:24 bremner: there can be some storms in the winter not too conducive to travel, also.
08:25 eli: And that is exactly why I want to do that...
08:26 eli: I love extreme weathers.  Deserts and frozen places.
08:26 eli: The whole new england thing with nice fluffy trees and such is not as appealing to me...
08:29 bremner: grass is always greener... ;)
08:29 eli: Yeah..
08:29 eli: But I grew up in a desert, and I loved it.
08:31 jamessan: deserts definitely have their own unique sort of beauty.  I couldn't live in a hot desert, though
08:33 eli: Real deserts are great.
08:34 eli: Ones where you can jump from a dune and dive into the sand.

08:38 eli: That's a more mild weather, but I can tell you that the first time I went to Utah the first thing that hit me when I went out of the plane is how great the weather is...
08:39 eli: jamessan: BTW, about your libpng patch -- Matthew pointed me at the new #:fail keyword for `ffi-lib', maybe you'll be able to try and see if that works?
08:40 jamessan: eli: ok, I'll revisit it this weekend.
08:40 eli: Thanks -- I can write some sketch code if it'll help.
08:41 eli: Actually, I'll do it now.
08:44 eli: jamessan: Something like this:
08:44 eli: (let loop ([lib+args ...])
08:44 eli: (apply ffi-lib (car lib+args)
08:44 eli: #:fail (let ([rest (cdr lib+args)])

09:02 bremner: doh.
09:03 eli: bremner: Yeah, that's more in case you're usually zoning out of the noise, and a direct email helps.
09:03 eli: You're off too now.
09:04 bremner: well, I might be actually, but probably between jamessan and I we'll catch what needs to be caught.
09:05 eli: OK.
09:07 otterdam: nice thing about lurking; sometimes you see people do things like using λ for sketch code, wonder why they don't use lambda, and then discover the shortcut for inserting λ in DrRacket
