06/10/2016, 1:00 PMnullability assertions are disabled for java interop, denoted by the
symbol! - k
kirillrakhman
06/10/2016, 1:00 PMit means, can be either, I don't know - a
aalmiray
06/10/2016, 1:00 PMI thought that Kotlin would err on the side of caution and automatically assume a Java method could return null when nullability annotaiton hints were not available - k

06/10/2016, 1:01 PMwe had that, it was aweful👍 2 - k

06/10/2016, 1:01 PMgreat talk - a
aalmiray
06/10/2016, 1:02 PMaha. it’s been a while since I last had a look at Kotlin (back in 0.5 I guess) where this feature existed - a
aalmiray
06/10/2016, 1:02 PMdid not know it was removed - k
kirillrakhman
06/10/2016, 1:03 PMthe basic problem is this: when you have
you can't convert it toList<Foo?>
in a type-safe way without expensive operationsList<Foo> - k
kirillrakhman
06/10/2016, 1:04 PMand
is the easy case, what aboutList
?Foo<Bar?> - a

06/10/2016, 1:07 PMOK. looks to me a have lots to catch up with Kotlin 1.o.2 - s

06/10/2016, 1:23 PMlots? like what? - s
sreich
06/10/2016, 1:25 PMoh, i read that as "kotlin has a lot to catch up with its previous versions' features" - e

06/10/2016, 1:37 PMI watched the first 15 minutes or so, but it looked good from what I saw 🙂 - e
evanchooly
06/10/2016, 1:37 PMi didn’t realize they’d posted that. and going right “after” andrey... - e
evanchooly
06/10/2016, 1:38 PMactually I presented at JavaOne last year with Svetlana in the room. I think @hhariri was there, too. - e
evanchooly
06/10/2016, 1:38 PMi wasn’t nervous about that one at all - k
kirillrakhman
06/10/2016, 1:39 PMhow's that adoption's going at mongo? - e
evanchooly
06/10/2016, 1:39 PMit’s not. 🙂 - e
evanchooly
06/10/2016, 1:39 PMthough I do have one issue against morphia relating to kotlin so I’ll probably write some tests in kotlin at least. - k
kirillrakhman
06/10/2016, 1:41 PMwhat would be a possible application for Kotlin at mongo, I wonder. some internal stuff maybe? Apart from that, I understand why you won't rewrite the Java driver in a whim. - e
evanchooly
06/10/2016, 1:41 PMi still want to write a kotlin wrapper for the java driver like we did for scala. - e
evanchooly
06/10/2016, 1:42 PMjust need language adoption first to sell that to management
