nwc10 he's just got to sleepsort and caused one member of the audience to crease up in supressed gigles 14:40
I don't think that she'd met it before 14:41
arnsholt Hehe. Sleepsort is a neat trick =D 14:43
masak though if you want to sort negative numbers, you have to find the minimum -m first, and then add +m to all the numbers during the sort. 14:58
and I guess sleepsort is not guaranteed to be stable -- it hits race conditions exactly when two numbers have the same magnitude.
worse than that, actually. I bet there's some threshold epsilon s.t. two numbers that are closer together than epsilon might come out the wrong order. like, can you guarantee that 3.0 and 3.000001 will be output in that order? 15:05

how about "godo" ?

 15:53
nwc10 although as jnthn made me realise (and I hadn't figured this out for myself), existing *symmetric* multiprocessing won't scale that far
so even what we have today isn't going to work
japhb__ lizmat: async works well on my ears, but maybe because I hear it all the time.
TimToady we could use "also"...oh wait...
jnthn TimToady: I'm working on a heretical S17 that describes all this stuff. Should land in the next few days. :) 15:54
TimToady wish
lizmat and when we have to wait to long for the result of the "godo", we're doing a "godot" -)

timotimo OK 15:55
geekosaur with some freakish stuff where it acts like a symlink to a common name
japhb__ nwc10: Yeah, last time I paid attention Moore's law was no longer about purely more cores, it was about more *types* of cores on the same die: CPU, GPU, codec, etc.
japhb__ wonders what the next trend for using transistors will be when they run out of different generally useful core types.
geekosaur moore's law is about transistors and cares now what they're doing :p 15:56
jnthn Even more cache :P
geekosaur *carees not

kanot tip3
TimToady someone needs to create a Perl 6 regex core
masak nwc10 (and others): I recommend www.gotw.ca/publications/concurrency-ddj.htm and then herbsutter.com/welcome-to-the-jungle/ as a kind of required reading for discussion on the present and future of concurrency.
lizmat jnthn: fwiw, I'm welcoming any changes to S17
15:56 ajr_ joined
nwc10 TimToady: wasn't that sort of what your previous employer was starting in the direction of? 15:57
TimToady well, it was a separate chip
and only really did 8-bit matching
jnthn lizmat: I'm just going to check in a S17-concurrency-jnthn.pod and let the community decide how to proceed :)
Rather than stomp on the existing one without any consensus :) 15:58
nwc10 TimToady: but that's more than enough for DNA?
timotimo japhb__: originall, moore's law is about density of transistors or something similar
rurban_ I came up with this: github.com/perl11/p2/wiki/Concurre...sign-study
japhb__ timotimo: I know. I was speaking loosely.
timotimo k
japhb__ I meant more "How it is being applied to the current pile of more usable transistors" 15:59
rurban_ Probably following Clojure-style immutable data, but with shared subkeys. The scheduler uses lock-free bags

lizmat is that the one where jnthn misses his foot? 16:07
masak jnthn: I (provisionally) disagree that callbacks are uncomposable, fwiw. 16:08
japhb__ jnthn: I notice that you're using method-local lexical classes a lot in the concurrency implementation, especially the pubsub work. Why is that? Are you settling on any rules of thumb for making that design decision?
masak they're composable, and nested callbacks result, and they're bad because languages have poor syntactic support for them.
not because they don't compose.
TimToady callbacks compose much better on the front end than on the back end 16:09
or rather, they compose just fine, except for the composing part
FROGGS ??? 16:10
jnthn masak: cdn.meme.li/i/peanw.jpg
TimToady if you end up with three separate hunks of code, I don't see what is being composed :P
arnsholt jnthn: I get an UnwindException when I do an Ops.findmethod. Is that supposed to happen? 16:11
jnthn arnsholt: no
It typically means somewhere that shold be letting one pass through is catching it
masak jnthn: :P
jnthn: case in point: jQuery's Deferred objects are chainable, syntactically easing the pain of nested callbacks. 16:12
jnthn: the chaining *is* composition.
TimToady though arguable the callback is often inside the first hunk of code, which is why I say they compose better on the front end than the back end
jnthn masak: Yes, the point being that it's the Deferred objects are the composable thing.
masak jnthn: well, it's the same thing as nesting, really.
nesting is composition, too.
TimToady yes, I know I'm just playing with the words here like a linguist ought to :)

arnsholt It looks like it's escaping all the way to the toplevel though

jnthn Does that have a catch somewhere?
And does it have a case for ControlException that just re-throws it?
arnsholt Ooh, no it doesn't 16:15
That might be it
masak jnthn: typo on slide 20: s/syncrhony/synchrony/
jnthn ah, no it doesn't
catch (Throwable t) {
throw ExceptionHandling.dieInternal(tc, t);

arnsholt But I thought findmethod returned null when it didn't find the method?
jnthn There are other ways things could go wrong I guess

japhb__ jnthn: While you're waiting, any thoughts on my method-local lexical class question above? 16:18
jnthn japhb__: It's because they are simply an implementation detail, not for direct use. 16:19
That is, you're not ever meant to talk about them.
You're only meant to talk about things as subscribables in the general sense. 16:20
FROGGS jaffa4: you had the chance to test froggs.de/perl6/rakudo-star-2013.10-RC1.msi yet?

FROGGS jaffa4: panda should work now
arnsholt jnthn: Two different findmethods is a bit confusing, FYI =p
jnthn arnsholt: Sorry :P
In my defense, they do both find methods :P
japhb__ jnthn: I kinda thought that was your reasoning. What about hackability? Are the method-local lexical classes only for things that make no sense to subclass and extend? 16:22
jaffa4 FROGGS: I will check it in 5 minutes
arnsholt True, but I still have no idea what's the difference between findmethod(ThreadContext, SixModelObject, String) and findmethod(SixModelObject, String, ThreadContext) =)
jnthn japhb__: Yes. You'll note that some combinators are done in terms of "on" rather than a lexical class.
japhb__: The way to hack is to write a combinator that does what you want. 16:23
Maybe using the existing ones from the outside
arnsholt: The second one is certainly the one nqp::findmethod maps to
'cus tc always comes last in those 16:24
japhb__ OK. I've got a nagging feeling at the back of my head on this one, but I'm suspending disbelief until I see how it shakes out.
jnthn So the first is internaly-er :)
japhb__: I'm not to attached to those, they're mostly inspired by the way Rx factored it
jaffa4 FROGGS: Failed to remove the directory '.work\1383409485_1\lib\XML\Parser\Tiny': rmdir failed: The directory is not empty. 16:25
jnthn japhb__: Though I didn't come up with a better way yet 16:26
FROGGS jaffa4: damn, it works here :/
japhb__ Sure. But I'm willing to believe it's reasonable partially because this encourages users to get out of the subclassing comfort zone and think in terms of combinators instead. Sometimes it's the gentle push in the right direction that is the most valuable part of an API design.
jaffa4 FROGGS: why?
jnthn japhb__: I kinda want the freedom to change the combinator implementations.
FROGGS jaffa4: why? I dunno
jnthn japhb__: So I really, really mean the lexical classes as an implementation detail 16:27
japhb__ Sure, I get that. 16:28
16:28 Guest80537 left
arnsholt jnthn: Right, that's a good rule of thumb. Using that one instead fixes the immediate problem 16:28

FROGGS .oO( the author )
TimToady and I'm fully expecting you to carp about it :)
jnthn I mostly like async because it's very clear that you're doing something asynchronously... 16:55
FROGGS and it is short enough
jnthn So long as what we pick is clearly saying "and this will get on with things in the background" or so, I'll be happy enough :) 16:56
lizmat I dislike async because it is has been used with different semantics already in Perl 5
jnthn wish does nicely capture the "your wish may not be granted" aspect f it.
lizmat: Has async been used widely enough in Perl 5 to make us worry about stealing it? 16:57
TimToady isn't "async" one of the things you had to define specially because it's not obvious? :P

japhb__ In src/Perl6/Metamodel/BOOTSTRAP.nqp, why does any class other than Attribute use BOOTSTRAPATTR? (Or once Scalar is defined, scalar_attr()?) 19:30
lue hello world o/ 19:35
FROGGS hi lue 19:36
TimToady S01:148 says -e is lax by default 19:37
synopsebot Link: perlcabal.org/syn/S01.html#line_148
FROGGS ahh, okay 19:38
TimToady actually, nowadays, we should probably use *; instead of 6; :)
FROGGS I didn't read the paragraphs containing relax
19:38 denis_boyun_ left
FROGGS use whatever? 19:38
well, it fits "I don't care" better 19:39
TimToady or maybe, *, dude;
FROGGS yeah
TimToady and maybe ; by itself also turns on all the golfing options :) 19:41
FROGGS we should totally give a \W characters a meaning in sink context :o) 19:42
like < would execute in reverse order
TimToady yeah, like #
FROGGS s/a/all/ 19:43
TimToady afk to avoid further damage & 19:44
FROGGS *g*
o/
19:44 Rotwang joined
FROGGS k, use/no strict works now 19:46
japhb__ Gah, gotta run. If anyone answers my BOOTSTRAPATTR question, I'll backlog, and be around again tonight PDT. & 19:48

Rotwang where can I find docs on the "run" subroutine? 20:27
20:30 Mouq joined
moritz Rotwang: S29 has a bit on run 20:30
Rotwang thanks 20:33
moritz but I'm not sure how much of the spec rakudo actually implements 20:34
20:39 risou is now known as risou_awy 20:40 Gwyxx left, hummeleB1 joined
Rotwang shell() does the thing I need, it would be nice if something like open(my $fh, "prog_name |") existed in p6 though 20:41
moritz open :p does that in rakudo (non-standard though) 20:42
:p, :w for writing to a pipe 20:43
Rotwang r: say "success" if shell("false") 20:44

Rotwang anyway it prints success in rakudo 2013.09, but probably shouldn't [; 20:45
moritz iirc we had some recent changes for that in rakudo 20:46
FROGGS yes, just a week ago 20:50
shell() and run() return a Proc::State now, before they just returned the exit code
