fasad is looking forward to a talk by RMS in his institute today :) 02:23
how is RMS as a speaker? anyone here heard any talks by RMS? 02:24
sorear I don't know anything about him as a speaker, but I've heard he's a horrible human being 02:25
especially regarded as such in geek-feminism circles
fasad oh ! 02:26
but still he's the father of OSS...

cognominal fasad, these days he tries to evangelize OSS but he tends to lose focus, insisting about calling Linux Gnu/Linux and desparaging Open Source as being evil. To the outsider it sound like a trotskyst badmouthing othet trotskysts over obscure catechism points. 03:24
*disparaging. 03:25
Critcizing him is easy. As a geek, I am not the last to forget to adapt my talks to the specific audience. 03:28

moritz what would @someLoL.tree(2, 2) do? same as .tree(4) ? 05:53
dalek kudo/nom: 33fb020 | moritz++ | src/core/ (2 files):
implement more .tree forms
 05:54
ast: f684933 | moritz++ | S02-lists/tree.t:
more List.tree tests
 05:55
moritz also it would be nice to get a sanity review for this commit 05:56
TimToady I suppose; I'd entirely forgotten about the numeric args
TimToady still wonders if it should be called .strata instead... 05:57
moritz I guess it only makes sense in combination with the closure form
.tree(2, *.map(&something), 2)
TimToady well, 2 is just sugar for *.Seq xx 2 (or whatever we do for Seq these days) 05:58
moritz maybe *.item
TimToady hmm, *.Seq xx 2 probably doesn' tdo the right thing...
{ .item } xx 2 is more like, I guess 05:59

sorear finds eirself in a defensive mood
bonsaikitten: You should know that attaching "'tards" to a sweeping overgeneralization like that is very unwelcome behavior here. 07:20
bonsaikitten sorear: I've filtered down my expression to about the minimal level I can use without not saying anything 07:21
sorear: I just really really hate people that want to control what I say or think :)
sorear it looks to me the other way around. 07:22
other people are using gender-neutral pronouns, and you're complaining about it.
please don't try to control what *I* think.
bonsaikitten no, they are trying to bend language
he-man becomes it-man!
TimToady bends language all day long 07:23
bonsaikitten I had too endure too much language corruption from female supremacists, it's easier to keep language as it is, even if "man" may be ambiguous
masak reads geekfeminism.wikia.com/wiki/Richard_Stallman and is astonished and sad 07:24
sorear "female supremacists"? are you serious?
bonsaikitten yes 07:25
they don't want equality
whenever we offer them equality they attack us at male pigs
so sad.
TimToady so don't be a pig
bonsaikitten TimToady: sorry, I have a penis by birth
TimToady: nothing I can do about that heinous crime against feminists 07:26
TimToady take it elsewhere please
this is not a hate channel
masak I don't think a good stance towards feminism is ridicule.
bonsaikitten--
bonsaikitten masak: I'm an egalitarian ... treat everyone equal, not create artificial divides
TimToady then stop acting like your manhood is threatened when it isn't 07:27
masak bonsaikitten: you're using language yourself that doesn't befit an egalitarian.
bonsaikitten: sorear called you on it.
bonsaikitten masak: I'm unwilling to compromise on facts 07:28
TimToady fine; don't compromise on them elsewhere please 07:29
moritz finds he doesn't understand List/LoL/Parcel at all 07:30
masak moritz: do you have excellent questions for us to ponder?
07:30 Patterner left
moritz masak: no, my current questions are more on the "wtf?" level 07:32
as far as I can understand, a List can contain (flattening) lists
and .[] and .elems etc. behave as if they were flattened out 07:33
Parcels can have flattening sublists too
and if you .lol a Parcel, it stops the sublists from flattening 07:34
masak "wtf?" is a question :)
moritz so far so good
masak aye.
moritz masak: but not an excellent question
now
masak no, granted.
moritz Parcel.list flattens out the sublists
and that surprises me
TimToady me too
that's why we have .flat 07:35
moritz because the List interface already keeps up the pretense of flatness
TimToady .list is supposed to be transparent to subparcels 07:36
moritz it is, but not to sublists 07:38

my guess is you're somewhere inland... :)
Su-Shee it's one of those treacherously sunny and bright winter days, just pretending to be pleasant.. ;)
08:39 mj41 joined
Su-Shee masak: berlin is on the tip of a weather tongue which brings us insane heat in summer (if you'd look onto a european map, we're the tip of balkan heat) and in winter we often get eastern winds and those bring the russian winter.. ;) 08:40
and there's only flat land between russia and berlin. nothing to break wind. nicely flat for 1000km
masak ouch. 08:44
you should put up, I dunno, like a wall to protect you from Eastern Europe... 08:45
Su-Shee man now I finally know why the weather went so weird.. ;)
masak ;)
Su-Shee goes rebuilding the berlin wall. it stood right in front of my building. should protect me nicely. 08:46
masak: why are you so warm in january in _sweden_?! 08:47
masak it got really cold around Friday/Saturday. but now it's back up to slightly below freezing again. 08:48

tadzik oh, I'm sure he want
jlaire hehe
tadzik erm, won't
you know, "It's Free Software! Not Open Source!" 10:56
fasad he himself said that him being called father of oss is possible only someone did artificial insemination and stole his sperms !
jlaire sounds like rms
fasad he also did his ""St. Ignutius" routine
daxim awesome. did he wear a poncho? 10:57
fasad with the "EMACS virgins joke"
yeh he did wear his poncho and his halo !

*spend 10:59

daxim I would be pretty pissed, too, if someone rained on my parade like that
moritz of course. The open source^W^Wfree software community would be much better off without linux</sarcasm>
Timbus hurds for all 11:00
tadzik oh-oh! It's GNU/Linux, remember!
fasad first thing, before anyone welcomes him, he says, "Please don't upload my photos on Facebook"
Timbus :I 11:01
mathw I can understand why he doesn't like Facebook, but that's a bit unreasonable. Then again, that's how I feel about quite a bit of what he says.
He his not a man who makes much concession to practicality 11:02
fasad though overall, his 'free software philosophy' does raise some good points
arnsholt Much? I'd say any
fasad mathw: yeah, he is an idealist
moritz GNU without Linux iist just a LTA TLA
fasad he told the students, make sacrifices, never work for Microsoft or any company which makes propiterary software 11:03
moritz: he did accept that GNU's kernel is far behind Linux 11:04
fasad is reading geekfeminism.wikia.com/wiki/Perl_is_my_bitch 11:09

jnthn phenny: tell not_gerd The GC bit is a little off, I suspect...STables can be statically marked/freed. And GC for objects should hang off the representation. Probably needs to think a bit about what existing Parrot v-tables actually mean. Some but not all are subsumed by REPRs. 12:49

jnthn phenny: tell not_gerd even when a REPR *does* seem to have a matching thing, it's not automatically the right answer. Consider get_integer vtable method in Parrot. It's used for HLL coercion interop, as well as unboxing. 6model cares about unboxing, but HLL interop isn't its (core) problem. 12:51

arnsholt masak: I think I agree with the general idea 13:00
I'd probably go for a syntax that is distinct from comments though
13:01 alvis left 13:02 skids left
masak arnsholt: yeah. I'm not settled on that yet. my idea was to use something that falls back gracefully in Markdown -- and any HTML, including HTML comments, will just go through the Markdown parser verbatim. 13:06
for a while I considered using \[ \] like LaTeX's math mode, but that seemed arbitrary.
I think I want some kind of delimiters, because I don't want to be restricted to a single paragraph. 13:07
arnsholt The idea I've been fiddling with is quite explicitly inspired by TeX (that is, macro-expansion), but with lispy syntax using [] rather than () 13:08
Yeah, for big figures you'll definitely want some way to split it into several paragraphs 13:09
masak Niobium is definitely inspired by my adventures with dlx-simple (which I'll need to blog about at some point).
arnsholt But making it gracefully parseable as markdown at the same time is harder
masak in fact, Niobium would be an excellent backend for dlx-simple!

not_gerd hello, #perl6 13:37
phenny not_gerd: 12:49Z <jnthn> tell not_gerd The GC bit is a little off, I suspect...STables can be statically marked/freed. And GC for objects should hang off the representation. Probably needs to think a bit about what existing Parrot v-tables actually mean. Some but not all are subsumed by REPRs.
not_gerd: 12:51Z <jnthn> tell not_gerd even when a REPR *does* seem to have a matching thing, it's not automatically the right answer. Consider get_integer vtable method in Parrot. It's used for HLL coercion interop, as well as unboxing. 6model cares about unboxing, but HLL interop isn't its (core) problem.
not_gerd: 12:52Z <jnthn> tell not_gerd Also type checking and method lookup don't need to be virtual. They only are in current 6model 'cus I didn't get around to making them not be so. I mean, sure a call to type_check or find_method in the HOW is virtual - it's just a method call. But the looking in the v-table or method cache or type cache need not be virtual.

not_gerd jnthn: thanks for your comments
jnthn: 2 questions:
1. do we actually need a repr-id - would the pointer do just as well?
jnthn REPRs are non-virtual. 13:42
not_gerd 2. why are things like SixModel_REPROps_Attribute not inlined into the REPROps table?
jnthn Well, let me make that clearer.
If you know statically what REPR a type has, they ain't. If you don't know then of course it's a runtime lookup. 13:43
2 - I find the grouping useful, but it doesn't have to be that way.
That is, there's no functional reason particularly. You could flatten it. 13:44
13:44 xinming joined
not_gerd but you start the first lookup with a repr's name, correct? after that, you could just cache the pointer to the repr instead of its id... 13:44
jnthn oh, that's what 6model does throughout
The REPR pointer in STable is a poitner to the struct.
*pointer
not_gerd sure - so where's the id actually used? 13:45
jnthn The numerical ID is more of a fossil now.
Even the serialization goes by name.
13:46 am0c left
jnthn So, we can probably do away with that. 13:46
Turns out that numerical IDs are a really bad idea when you start dynamically loading new REPRs. :) 13:47
Note that REPR function tables need not be GCable. 13:48

well, up to the point of giving the appearance of cheating, but that's on the pragmatics level, as is the fast that it runs faster 17:33

17:36 cognominal left 17:37 cognominal joined 17:39 tarch left
TimToady there's probably some generic optimization in here over any reduction operator that caches a few partial results on constant ranges and can quicky locate the largest prefix of the list that has already been calculated, and just start from there for the new tail (assuming a left-associative op; right-assoc would have to count from the other end) 17:40

TimToady so even if you didn't have the n(n+1)/2 optimization, it might've already calculated and cached [+] 1..99856 at some point, so can start from there 17:44

TimToady uh

TimToady jnthn: ^^ apparently doesn't autogen the default [+]
jnthn TimToady: uhm. Well, I guess not. It looks in the symbol table and sees there already is one there... 18:27
TimToady: Er, deeper than that... 18:28
TimToady: They desugar to higher order functions
TimToady: Not sure what the best way to handle that is.
I guess it's not so hard to add the auto-generated one as a candidate. 18:29
But...how to know it wasn't already generated... :)
pmichaud that's what we used to do, yes.
TimToady the spec suggests &prefix:<[+]> := reduce... but that doesn't necessarily make a multi
jnthn No, we ain't making a multi there
pmichaud how to know it wasn't already generated == we handle it in a scoping context, iirc 18:30
TimToady so does the multi declaration trigger a local proto gen?
pmichaud ...what TimToady++ said :)
jnthn TimToady: Yes.
TimToady: Er, your one does
Oh...
That means that we can spot it's a proto, not an only
But then we get into bother when we auto-gen it before we see your multi. 18:31
TimToady why, if it's more genericly sigged?
jnthn TimToady: No, if we generate it as an only it causes issues
TimToady well, er, then don't... 18:32
jnthn TimToady: We'd need to generate it as a multi if there's none in scope, or if there is one then know whether we've added the default candidate to it yet or not.
TimToady why isn't there just a default proto for everyone?
jnthn ...becuase protos aren't default fallbacks any more? :) 18:33
TimToady not claiming that
jnthn OK, then I'm not quite sure what you're suggesting.
TimToady I just mean an outer proto {*} and then a default multi
18:34 MayDaniel left
TimToady default by virtue of generic sig, or maybe 'is default' as latest spec change shows 18:34
18:35 fasad left
jnthn *nod* 18:36
TimToady just saying if there's always a proto [+] then there's never a need to autogen a local proto
jnthn Will have to have a dig...when I get tuits. :)
TimToady: Yes, true.
TimToady we'll figger it all out one of these millenia...
jnthn: it would also be awesome if somehow the dispatcher failure error could've pointed out the need for :$excludes_* 18:43
like a list of, for each each candidate, why it didn't match (possibly pooled by sigs that have the same reason) 18:44
jnthn TimToady: Yeah, I was pondering how best to do that.
TimToady These sigs don't match because you're an idiot: :)
These sigs don't match because the programmer was an idiot: 18:45
benabik How do you ignore some args in a subsig? Range (:$min, :$max, *%) ?
TimToady These sigs don't match because I don't feel like it today:
yes
what jnthn initially did above
but in this case, we didn't want to ignore them, since they matter
jnthn The info is all there, it's just that we don't tend to bother generating the failure messages in a multi-dispatch as we expect them to usuall work out :)

leontopod Is Perl 6 Version 1 out yet? 20:52
tadzik I think it knows stuff cross-channel
leontopod: Perl 6 is not versioned, as far as I'm concerned
moritz at least not yet
tadzik compilers are, and they have versions like 14 or 40-something
moritz is C++ version 1 out yet?
or C version 1?
benabik Yeah, seen will return results for both channels. But seen <badIRCnick> returns different things. 20:53
tadzik aye
leontopod there is K&R C and ANSI C
flussence
.oO( I thought C was up to version 99.. )
leontopod is there going to be ANSI Perl 6?
TimToady perl6: say "I am the first version"
p6eval pugs b927740, rakudo 33fb02, niecza v14-19-g256172a: OUTPUT«I am the first version␤»
moritz leontopod: and which one is Version 1?
leontopod K&R I would say
that book defined the language
just like C language defines Perl 5
benabik flussence: They've updated. C11 is the new hotness. (99 < 11?) 20:54
moritz anyway, I don't think Perl 6 will be ANSI any time soon
TimToady that's because it's un-American
moritz I'm also having a difficult time imagining ISO Perl 6 :-) 20:55
leontopod there will have to be an ANSI or ISO standard sooner or later
PerlJam leontopod: because ... ?
moritz really?
perl 5 does well without 20:56
benabik leontopod: Is there an ANSI/ISO PHP, Python, or Ruby?
TimToady well, let's go for "later" then :)
moritz so do ruby, python, lua (I think) and lots of others
I don't even know if javascript has an ISO standard
leontopod ecmascript
tadzik leontopod: do you mean, somewhat, "is it production ready, production-approved?"
20:56 rindolf left
PerlJam leontopod: ecma isn't iso :) 20:57
leontopod tadzik, yah, we got to get real word people using Perl 6 to work on real world problems
TimToady um, already happening
leontopod controlling nuclear reactors, avionics, medical instrumentation, stuff like that
moritz leontopod: then welcome to the real world. Have fun solving problems in Perl 6.
TimToady but the knee of the curve is probably a couple years out still, for sure
moritz the easist one to convince doing stuff is yourself 20:58
TimToady we're not interesting in Perl 6 being adopted too rapidly
PerlJam TimToady: but I've been thinking that for about 7 years now ;)
benabik leontopod: If "production ready" means any field where line-by-line code review is involved, then you're pretty much dealing with Cobol or C.
TimToady well, it's always true, depending on how you label the graphs :P
flussence or MUMPS
masak leontopod: when people come here and ask "is Perl 6 released/ready/production-spiffy yet?", I always hear "should I start using Perl 6 now, or should I wait some more?"
TimToady and for some time, the answer has been "Well, it depends." 20:59
it's not quite ready to write an OS in...
masak it depends on who you are, yes.
eviltwin_b wouldn't MUMPS be more character by character?
leontopod can Perl 6 be written in Perl 6 yet?
tadzik it already is
leontopod THAT would be a neat milestone
PerlJam masak: I hear "is there a good business case I can make to my coworkers for using Perl 6?"
TimToady not only can, but is
leontopod cool!
masak leontopod: we're already doing that.
leontopod Perl 6++
masak leontopod: check out the src/core directory in Rakudo. 21:00
TimToady well, at least most of the compiler bits
masak and some src/mumblemumble in Niecza.
TimToady you still have to have a core in something else, a VM

masak yeah, but Yapsi is magical.

moritz so if we run out of both, we know who is to blame :-) 21:01
masak we passed Peak Pixie Dust in 2006. not my fault. :) 21:02
oddly, we haven't passed Peak Hope yet, although much of the rest of the programming world has...
TimToady leontopod: the really bad thing about writing a compiler in the same language is that, if the language is slow, everything is doubly slow. otoh, every optimization speeds up both the compile time and run time, so it's a long-term win
masak and we're getting ready to do some awesome optimizations. 21:03
today we were discussing optimizing away sums of ranges into just a constant-time expression.
and... it already works in all implementations!
moritz it does?
tadzik huh, I did miss something, didn't I? 21:04
masak well, not the optimization.
but the code for overriding prefix:<[+]>
I was surprised at that.
moritz last I tried, adding a prefix:<[+]>(Range) multi would make the default go away
masak oh :(
didn't try that bit.
TimToady and that's what we discovered today, but jnthn++ is aware of it
