japhb sorear, why doesn't niecza compile the setting when you `make`? 03:48
Or is there a different make invocation now that I should use instead?
sorear japhb: it does, but niecza by default can't find the setting you just compiled
japhb Oops
sorear if you run niecza without arguments it assumes it is in installation mode and puts all its writable data in $HOME 03:49

moritz which movie? 09:28

really a tropefest like few others.

daxim ewww, it's got kissing in it.
tadzik gross 09:33
masak I guess it does. but I don't especially remember any kissing, so it must be explipsed by all the other things in the movie :)
eclipsed*
by the way, is Eclipse called that because when you start it, the lights dim in the rest of the house? :P 09:34
moritz masak: I guess because they wanted to conquer Sun
now they should call it 'well', because an Oracle can fall into a well 09:35
:-)
masak :D
I thought it was philosophers that fell into wells.
Oracles are more likely to be tarred and feathered, or to have their eyes poked out. 09:36
daxim warning: do not look into stick with remaining eye
masak *lol* 09:37
I want to spend the rest of my life in the company of people smart enough to produce snowclones on existing memes.
moritz wonders when Ronja will start doing that 09:40
masak the thought is dizzying. 09:41
moritz speaking of her, she usually communicates with single words or two-word-sentences
09:41 birdwindupbird joined
moritz but sometimes she surprises us with fully formed sentences 09:41
one she surely picked up verbatim, "willst du noch mehr haben?"
masak moritz: I remember when my nepwhew did two-word sentences. that was cool to observe.
moritz but one she must have crafted on her own: "Papa, da ist die Nase!" 09:42
masak :P
moritz it's amazing how expressive you can be with one or two words, if that's all you have
09:42 kresike joined
kresike hello all you happy perl6 people 09:42
masak moritz: at one point, he wanted to express the absence of a dog in some context. so he said first "inte hund" and then "hund inte". which I found interesting from a language development perspective. 09:43
moritz \o kresike
masak hello happy kresike! \o/
moritz: we could all learn from that two-word expressivity.
moritz is sv:inte the same as no:ikke?
masak moritz: yeah, we are the ones diverged on that 'un.
daxim masak, I wonder whether you knew about the website TMOL, a prototypical q&a-site (modeled after enwp.org/Conversatron and the like), but with its unique blend of video games, oughties' pop culture and buddhism, the answers snocloned quite a bit 09:44
moritz btw Ronja recognizes herself in the mirror, but doesn't yet have a word for herself

Su-Shee easy. cook a lot of espresso with the cream before you add it to the truffle ganache. if you like, you can also crunch coffeebeans and caramlize them and add those too. 14:14

Su-Shee tea truffle made accordingly, just don't add caramelized tea leaves ;) 14:15

masak from en.wikiquote.org/wiki/Linus_Torvalds#1991 -- "The Hurd 0.0 was released in August 1996 and as of 2011, is still not complete." 17:08
we need a name for the fallacy of "is still not complete". 17:09
because, as we all know, the nice thing about Linux is that it is complete and that people have stopped improving it. :P
FROGGS GNU Hurd still today is W.I.P, maybe even R.I.P
hehe
masak I'm not disagreeing.
I just think the "is still not complete" description is low-bandwidth enough to be positively misleading. 17:10
just as it is with Perl 6.
FROGGS ya, about Perl 6 I'd say the improvement is going on
masak I rush to add that I think there are a lot of things Perl 6 doesn't do well enough yet for people to consider it ready for them. 17:11
we need to identify those areas and focus on them.
I think we at least partially are succeeding in doing that.
not_gerd see news.ycombinator.com/item?id=4576487 ;)
FROGGS masak: the major problem IMO is that it is so damn slow 17:12
If I had to replace my SOAP stuff at work using perl6, I guess it will be at least 20 times slower, even if it was precompiled 17:13
masak not_gerd: I would agree more with "is not a very good marketing tactic", if I hadn't seen a number of big Perl 5 names come around to Perl 6 and start considering it seriously recently.
FROGGS the second major thing is the lack of important modules
masak FROGGS: yeah. speed is an ongoing concern.
and we absolutely *need* good Perl 5 integration. that will be a watershed thing. 17:14
oh, I suspected this thread would be found under the "Python is doing just fine" article ;) 17:15
[Coke] masak: are you suggesting that Hurd is a useful and usable toolset? (and used?)
not_gerd masak: I mainly posted that because I just read it a few minutes ago, not because I share that opinion
masak I don't think it's a proper use of frames to give a post that title. the comments seem to corroborate that. "You know what? The very fact that you are having to write this post means Python isn't doing just fine."
not_gerd incidentally, the thread is about *Python* not being dead
not_gerd fails at reading before writing 17:16
masak [Coke]: no! I just have an unhealthy researcher-like interest in other long, drawn-out development efforts that a smallish number of people keep contributing to.
17:17 aloha left, ggoebel joined, spider-mario joined
masak [Coke]: the Hurd was *probably* killed off by the advent of Linux. I consider the likelihood that it'll play any major role in the future very, very low. 17:18
it could also be that microkernels are actually worse than monolithic kernels, in practice, even though they look more pure on paper.
17:18 leprevost left, wamba left
masak that seems to be what Linus argued against Tannenbaum back in the day. 17:19
but I'm not actually savvy enough to weigh in on that.
not_gerd: well, both Mystery Science^W^WPython 3k and Perl 6 are "failures" each in their own way, on different scales. both may still prove to be influential. 17:20
17:20 arlinius left 17:21 leprevost joined
masak saying "Python is doing just fine" is a bit like saying "There is absolutely no cause for concern". :) 17:21
[Coke] masak: like my HR rep saying "This doesn't mean we're looking at a headcount reduction" 17:22
doy it is a nice contrast to the constant flow of "perl is dead"/"perl is not dead" articles from a couple years ago
(:
masak [Coke]: man, "headcount reduction" sounds like you wanted to make "firing people" sound like "chopping off people's heads". 17:23
doy: it's Python's turn not to be dead. :P 17:24
masak pre-empts all "pining for the fjords" jokes
not_gerd that's appropriate for Parrot as well...
Su-Shee well once there was tcl and mostly perl and now we share the realm with perl, python, ruby and recently javascript..

masak I'd like to bring discussion of github.com/perl6/specs/issues/24 onto the channel. 19:06
I've already expressed my opinion in the comments of that issue.
interested what others think.
moritz I'd like to mention that Bool is an Enum too 19:08
if all enum elements should be True in boolean contenxt, that would be very bad for False
masak heh :)
I agree. I didn't think of that case because I think it's more fundamental than that. 19:09
geekosaur I would think random enums should not have Bool instances. Bool itself should, obviously
masak geekosaur: sorry, what?
moritz that said, I can see why the current state of affairs could be seen as LTA 19:10
masak "have Bool instances"?
moritz maybe we should make enuma values start with 42 (or 1 or so)
FROGGS If someone starts a vote, I vote for the current (C-like) implementation, the first enum (if it is zero) should be treated as false
moritz: can I declare another start value like in C?
masak moritz: I think sirrobert is arguing for making his preferred use case (so = defined) the default.
moritz FROGGS: sure
sorear I have a gut feeling that the currnent impl is just a little bit too magical 19:11
masak moritz: (and I don't like that)
moritz r: enum A (b => 42, <c d e>); say A.enums.perl
p6eval rakudo 16f22b: OUTPUT«===SORRY!===␤Method 'returns' not found for invocant of class 'Parcel'␤»
FROGGS good, so somebody who wants to use 'so' to check for definedness should use enums starting with 1
moritz rakudobug
geekosaur hm, wait, this is perl6. I'm misremembering what else boolifies automatically though; if other types do, then enums probably should
moritz r: enum A (b => 42, 'c', 'd', 'e'); say A.enums.perl
p6eval rakudo 16f22b: OUTPUT«("b" => 42, "c" => 43, "d" => 44, "e" => 45).hash␤»
FROGGS very good
r: enum A (b => 42, 'c', 'd' => 77, 'e'); say A.enums.perl 19:12
p6eval rakudo 16f22b: OUTPUT«===SORRY!===␤Method 'returns' not found for invocant of class 'Pair'␤»
19:12 cognominal left

FROGGS good
masak moritz: shall I submit the above as a rakudobug? 19:13
r: enum A (b => 42, <c d e>)
p6eval rakudo 16f22b: OUTPUT«===SORRY!===␤Method 'returns' not found for invocant of class 'Parcel'␤»
masak looks like something that oughta work.
moritz masak: please submit
sorear masak: and it clearly should not fail like that
masak submits
moritz I think I know how to fix it, though jnthn might not like the fix. sorear will though :-)
sorear masak: I think it's trying to treat a parcel as QAST node 19:14
masak moritz: you have too much knowledge of the internals of our implementors :P
sorear is curious :-)
theoretically you should be able to do enum A < :b<42> c d e >
might need to use «» instead
masak yes, I think it does. 19:15
sorear n: say val(':b<42>')
p6eval niecza v22-6-g9e5350d: OUTPUT«:b<42>␤»
sorear n: say val(':b<42>').WHAT
p6eval niecza v22-6-g9e5350d: OUTPUT«Str()␤»
moritz masak: the fix is to call $*W.compile_time_evaluate on the expression, instead of trying to obtain the return values from the AST
masak moritz: sounds sane to me.
moritz and doing some kind of half-baked constant folding, as we do now
s/and/instead/
but last time I did that for some values, jnthn didn't like the approach 19:16
whereas sorear uses it in niecza for a variety of cases already
so, that's what my quasi-cryptic statement was about :-)
masak all noted in the rakudobug ;) 19:18
Tene worrydream.com/LearnableProgramming/ -- another great article from Bret Victor

masak Tene: I beat you to it ;) 19:18
Tene :D 19:19
masak <masak> I find Bret Victor's ideas fascinating, and I want to subscribe to his newsletter: worrydream.com/LearnableProgramming/
moritz don't beat a dead hor... oh wait
19:22 thou left 19:24 thou joined
masak but yeah, Bret Victor gets dupes on the channel because he has really good points. 19:26
when I read this one (and sometimes with other things), I wonder how well his ideas would scale. 19:27
I guess that's the big challenge, and the reason we don't already have more of what he's proposing.
Tene That's exactly what I was thinking; these microexamples are nice, but I'm having trouble thinking of their applicability to any programming I've done recently. 19:30
masak there's another point which bothers me about it.
it's not scale so much as concreteness. 19:31
in order to get as good visualisations as he gets, you can't stray very far from being very concrete and un-generalized.
and sometimes you want to abstract over, say, a coordinate or a color.
his examples never do that, mostly because they can't. they're all loops and the like in mainline code. 19:32

Tene Although, the title *is* "Learnable Programming" 19:35
masak indeed. and the ideas are still interesting as such.
cognominal Perl 6 as a "natural" language is not optimized for learnability. So any thought about making an environment to make Perl 6 learnable is good. Even if learning a language is different from learning to programming. On the other hand, one needs a language to program. 19:39
moritz cognominal: Perl 6 is very much optimized for learnability
GlitchMr say 'Hello, world!';
It's easy to learn
Compare "Hello, world!" in COBOL or Java
You don't have to describe types. 19:40
You don't have to use MAIN sub
All you do is just type statement
And it just works.
Isn't it easy to use/
?
Tene "easy to use" is very different from "optimized for learnability" 19:41
cognominal I have not a TimToady quote ready but learnability comes second to expressivity.
Tene Perl 6 is optimized for people who know the language first 19:42
GlitchMr Yeah... surely if you know let's say Python, learning Perl 6 is easier 19:43
Tene The goal is to have a great tool; if you make sacrifices to optimize for someone's first few days using the language, they're going to keep paying that cost for the entire rest of their use of the language.
There are *also* plenty of considerations for new users, but experienced users tend to take priority, from what I've seen.
GlitchMr Why they would pay that cost for the entire rest of their use of that language?
And what those "sacrifices" are? 19:44
I surely don't think that *%*@!%(@!&*^(!^*!*@%* being syntax error would be harmful
std: *%*@!%(@!&*^(!^*!*@%*

Tene I don't have a reference for an actual description of this policy, it's just what I've seen from conversations here 19:45
GlitchMr: they're not directly opposing forces, just different priorities in optimization.
cognominal Tene: "experienced users tend to take priority". Agreed, but that's why we end up with PHP. People growing with a brain dead language for fear of learning what is there.
GlitchMr Tene: Perl 6 makes it easy to make good programs
When you know language, that is
sorear I am amazed by the variety of opinions on #24 19:46
GlitchMr Let's say you have BASIC background
He could even use gotos
And yes, Perl 6 allows him to use that rope
It's rarely neccessary, but it's there when you need it

masak cognominal: TimToady has said something to the effect of that we're not aiming to make Perl 6 people's first language, but people's last language :)
cognominal indeed 19:49
GlitchMr masak: After COBOL, Brainfuck, PHP 6 and Python 4 19:50
Am I right?
masak um. 19:51
GlitchMr It's "last language", isn't it
So you would have to learn Python 4 first

cognominal on the other hand, as a grown up, it is difficult to learn language that starts with different basics. There is much unlearning in learning. Or more exactly one must know what is relevant to the context of a different language. 20:00

sorear [Coke]: I would still think the behavior is weird, but honestly at this point I've lost interest in fighting it
masak sorear: please be more specific. 20:02
(even if you've lost interest in fighting it)
sorear masak: enums other than Bool with numeric value 0 being considered false feels excessively magical to me 20:03
[Coke] on the contrary, it feels entirely logical to me. 20:04
but then, I think of the enums as a stand in for a bunch of constants.
FROGGS C-like
20:04 rurban joined
moritz aye, that's my understanding too 20:05
and the stringification to the enum name is just a bit of extra magic to make it nicer
sorear my reasoning is that 80% of the time, my enums don't actually have semantically relevant ordering 20:06
enum PhaserType < INIT END BEGIN START CATCH CONTROL ... > 20:07
if $some-sub.phaser { ... } # oops, this should have been .defined
masak "doctor, it hurts when I do this"
I can't stop people from using the language without knowing how things boolify. 20:08
moritz having a different default value than 0 would solve that problem without adding special magic
masak it would. but the default should clearly be 0.
[Coke] yah. I see no real issue in making the default start value 1.
masak: why?
sorear it's a gratuitous sharp edge.
masak because everything else starts at 0 in Perl 6.
just like moritz pointed out in the Github issue. 20:09
[Coke] masak: when are you checking the numeric values of an enum?
moritz forcing people to provide a start valeu would also work
leont Why wouldn't they start with 0 but true?
masak moritz: I like that better.
[Coke] that also seems vaguely reasonable, leont.
masak leont: I think '0 but True' is basically considered a code smell at this point. 20:10
leont The numeric value shouldn't matter, even if it was randomly distributed
[Coke] r: say ?(0 but True)
moritz leont: because all uses of "but"... what masak said
p6eval rakudo 16f22b: OUTPUT«True␤»
moritz what about making the defualt value not numeric, but string?
masak '0 but True' is an idea which sounds great, if it's the year 2000, and no-one has tried it in a language :)
sorear doctor, it hurts when I step on the exposed nail in my door threshold
we can either: tell people to be more careful, or: fix the problem 20:11
moritz enum A <B C > # same as enum A (B => 'B', C => 'C');
[Coke] that's not horrible.
masak sorear: I see what you're saying. I just don't consider the 0 an exposed nail in my door threshold.
moritz: I could live with that, I think.
that would force people like me who like the numbers to declare them explicitly. 20:12
moritz and if you need a numeric enum, you can always make that happen by using a first value
masak and everyone else gets their truthy strings.
leont Hmmm, that may actually make sense too
sorear but now that I've explained my position, I'd rather live with the status quo than spend more energy debating a replacement
masak that works for me, too ;)

skids Hrm. In 09-rc1 there is something different going on with Failure. For example if you include a file that has a "fail('foo')" in it, you get "get_attr_str() not implemented in class 'Failure'' 20:29
But if it is in the mainline file, it doesn't do that.
