12:00 jgracin: hi rich!
12:00 rhickey: hi
12:01 jgracin: Any thoughts on why this loop http://
12:02 it takes 45 seconds for n = 2 000 000 000
12:02 while other versions do it in less than 2 secs
12:06 rhickey: numbers are always boxed in Clojure, no matter what the type declarations, CL has tagged architecture and Java/C math wraps
12:07 jgracin: Oh, ok. Thanks!
12:08 rhickey: Clojure is not going to keep up with typed languages or CL on arithmetic any time soon. Function calling with type hints is as fast as Java
12:11 jgracin: I get it. Seems like a reasonable design decision to me. Especially since Java integration is so easy.
12:12 rhickey: Given ASM is included, it might be possible to build a number-crunching DSL in Clojure itself, but it's not on my agenda
12:15 jgracin: Indeed, how cool!
12:18 i was in the process of trying to forget Java when Clojure showed up and put Java in a completely different perspective.
12:19 rhickey: It's a great platform
12:25 jgracin: do you have any hopes regarding the further development of JVM? Any particular feature that would significantly affect Clojure?
12:27 rhickey: I'd like to see boxed math support - all dynamic languages for the JVM have to contend with that,
12:27 tail-call optimization would be nice,
12:28 but because I designed for the present, Clojure is well poised for any HotSpot optimizations
12:29 for instance maybe someday hotspot could optimize your bm function
14:17 jonathan__: wow, two me's
14:21 I've read that the JVM can't do continuations, but isn't a closure, or a lazy cons roughly equivalent?
14:25 rhickey: not really. lazy-cons lets you do some of what you can with continuations, but continuations are much more general - kind of like a restorable snapshot of the call stack
14:27 jonathan__: ahhh, so they let you stop a 'stream of execution' for want of a better phrase?
14:28 I'm trying and failing to understand the patent on seaside etc., on reddit
15:56 bgeron: the patent?
16:03 jonathan__: yes
16:03 There's a reference to a paper ... http://
16:04 typical paper, most of the steps seem to be skipped
16:04 blah blah blah ... presto!!!
16:05 I bitterly remember trying to understand the concept of local variables ... that took a leap
16:09 bgeron: have you programmed with continuations?
16:55 bgeron: I know how they work and so
16:56 (sorry to respond so late)
17:02 * bgeron needs to reimplement call/cc in his pet-lisp-on-cl as a function, not as part of the evaller
17:03 bgeron: well, part of the evaller, but cleaner
17:18 Tarka: I should be able to eval *current-namespace* at the repl shouldn't I?
