comborico1611 I'm back. Good supper. Homemade hamburgers. 01:15
ivans sounds nice
what did you put in them?
comborico1611 They are so easy and fast to make, as well.
Salt and pepper, onions, ketchup. 01:16
My brother actually puts ingredients IN the meat. Wortstershire, i forgot the rest. 01:17
ivans it's weird how homemeade food tastes so good
even if it's the simplest thing in the world
lookatme China hamburgers :) 01:18
comborico1611 For some foods homemade is amazing. For others, not as good as professional. I'm thinking steak here.
ivans for sure, there's a place for professionals
one of the best meals I ever had was a nice big steak in canada 01:19
I've noticed some active people on projecteuler.net using Perl 6, is anyone of them on this channel? :) 01:20
the solutions I've seen on the forums is a big reason I'm interested in Perl 6 again
looks like a proper useful language now
comborico1611 Not me. I'm not that into math. 01:21
What about China hamburgers?
ivans I have no clue what that would be 01:22
TIL
MasterDuke heh. i was working on a projecteuler.net problem in Perl 6 and it wasn't running fast enough. i started looking into the rakudo compiler and ended up contributing to Rakudo, NQP, and MoarVM
01:22 troys is now known as troys_
MasterDuke but still haven't solved that problem 01:22
timotimo i imagine china hamburgers are really hard to chew and also cut up your mouth from the inside when you try to eat them
comborico1611 Heh
ivans MasterDuke: :D
I really like chinese food in general 01:23
comborico1611 I need to go back a self-study mathematics.
ivans had some just the day before
comborico1611 American Chinese food is the best. 01:24
ivans comborico1611: I'm studying (re-learning) math on my own right now
lookatme If you interesting in china food, I recommend you watch video of "The food ranger" on the Youtube
comborico1611 What branch are you in now?
ivans "mathematics and its history" is a very nice book to get an overview of different areas
comborico1611 Lookatme, ty I'll check it now. 01:25
ivans I skimmed through it once, now I'm reading it again carefully
comborico1611 Hmm. I love history, so that sounds great.
ivans it's a really nice splend of history and actual math
I think it'll take me a year to finish this careful second reading 01:26
comborico1611 I bought a math book that sounds similar. It is a classic. Can't remember the name. Not sure why i didn't finish it.
ivans I've started 50 math books for every one I've finished 01:27
01:27 ryn1x_ left
ivans so nowadays when I pick up a new one, I'll plan to read it twice 01:27
comborico1611 I believe it. For me, Math is a subject that has to have a talented teacher, or i don't understand. 01:28
ivans first time I'll skip everything that's too complicated and just skim
comborico1611 That is a wise strategy.
ivans and if I liked the 1% I understood, I'll go over it again
incidentally, I re-read "How to read a book" this year
comborico1611 Hmm.
01:29 margeas left
comborico1611 I never thought to study such a subject. Makes really good sense to, now that i think about it. 01:29
lookatme Also I heard there is a snack bar under the Empire State Building in NewYork sold China hamburgers from ShanXi (China city).
comborico1611 Heh. 01:30
ivans if I ever visit the US, I'll check it out :
:D
the images I got from google look tasty
just like most asian food
lookatme Yeah, if you want try Chinese food, welcome to China :) 01:31
comborico1611 Asian food is the best in the world. Then, Mexican.
timotimo the best pizza i had in recent memory was from a chinese restaurant (for delivery) 01:32
comborico1611 😆
MasterDuke heh. the best neapolitan pizza i ever had was in tallin, estonia. better than the place in naples, italy where the pizza was invented 01:33
01:34 ryn1x left
comborico1611 Man, you get around. 01:34
01:34 ryn1x joined
MasterDuke every once in a while, i do like to travel when i get the opportunity 01:35
01:35 dugword joined
comborico1611 I like cracker-thin pizza OR new York style. 01:35
MasterDuke chicago-style is actually my favorite. i was just in nyc, but i don't really like their pizza 01:36
ivans I've been travelling for quite a few years now
nothing's better than local asian food
MasterDuke i've never been to that part of asia, but would love to get there sometime 01:38
01:38 kalkin-- joined
comborico1611 I must be in the mood for Chicago (deep dish) pizza. 01:38
ivans I've managed to find surprisingly good pizza everywhere in south-east asia I've been 01:39
even my Italian friend had no complaints, and that's saying a lot
comborico1611 lol 01:40
ivans there are so many expats that decide to buy a restaurant and show how it's really done
comborico1611 Interesting. 01:41

raiph wander: yes. some adverbs apply *inside* the *declarations* of regexes, others apply to *matches* see docs.perl6.org/language/regexes#Ma...ng_adverbs 04:55
wander how about the difference between 'rx:g' and 'm:g' 04:58
05:02 astj joined 05:03 dj_goku joined
raiph m is a match operation that can take match adverbs; it just happens to include a regex declaration in its syntax 05:03
rx is a regex declaration that can't take match adverbs; it just happens to sometimes be immediately run if in sink context or rhs of ~~ 05:04
wander: ^^ 05:05
wander i got it

piojo Is there any way to do a parallel "for" loop? This doesn't work: for @objects.race { } 05:20
I've been using .race.map (conceptually this is a mismatch), or for @objects { start { ... } } (this is slower)
geekosaur you may be looking for hyperoperators? 05:21
05:21 Cabanossi left
piojo geekosaur: don't those only work with functions/operators? 05:21
I couldn't get hyper operators to work with a block, but perhaps my syntax was just wrong 05:22
05:22 Cabanossi joined
geekosaur I'm not sure if you need to define your own operator to make the syntax work. think there's some evil abuse of [] ? 05:26
05:28 cdg joined
piojo geekosaur: abusing `map` (using it in sink context) is less evil than abusing operators. Unless there's something I just missed in the docs, like @a».{ ... } 05:29
05:33 cdg left
piojo is there a method which invokes a block, like a method version of `given`? 05:33
this definitely doesn't work: <a b c>».given( -> $obj { logic here }) 05:34
geekosaur actually, I think you just want the example for race. map and for are not so different 05:37
05:38 ryn1x joined, mempko joined
geekosaur in fact, in the perl 5 community there's a thing about people using map instead of for, which is wasteful because it builds a result list only to throw it away 05:39
05:39 wamba left
geekosaur but iirc in perl 6 for builds the result list anyway, so not even that difference 05:39
piojo geekosaur: but in perl6 it's faster to use .race.map than to call 'await do for { start { } }'
oh, I didn't realize calling map wasn't wasteful
05:42 ryn1x left 05:46 napo1eon joined
piojo still, this is such awkward syntax, there should be a better way. I think I'll ask on SO 05:57
IMO, calling map in a sink context should give a warning, since it's likely that `@foo.map` should be `@bar = @foo.map` 05:58
but it's still the fastest way to do concurrent iteration with a block 05:59
geekosaur yeh. it's actually worse than that, we tend to rely on stuff in sink context doing something (at least wrning) but a list or hash that is sunk silently vanishes
which includes, say, Failure-s embedded in the list/hash 06:00
so they never throw

piojo geekosaur: oh, that is quite bad 06:32
geekosaur the flip side is you don't want to wait for everything in a 1000000 element list to be sunk 06:33
which makes me wonder if things like for need to be aware of their context and propagate it to the block 06:34
but that probably has its own problems
piojo Also, I notice "await do for @foo { start { ... } }" also does not print failures
so that makes the "map" case less problematic, if the competition exhibits the same symptom 06:35

lookatme On my PC(opensuse 23), race is slow than normal iteration 07:44
The for loop took about 3.20s, and the race is 9.80s 07:47
And hyper took 9.70s

lookatme IDK, I set batch to 100000, it still took 6.0s :( 08:11
wander do we have Class like bitset? 08:12
or say bitmap
moritz this was with rakudo 2017.10-132-g1c38715
08:12 Mrofnet left
lookatme Here is This is Rakudo version 2017.10 built on MoarVM version 2017.10 08:13
piojo lookatme: the actual example is searching a file: $path.IO.slurp.contains($str) 08:14
It's a little slower, and it shows the difference between .race.map and await do for { start { } }, though they're both much faster than normal loop 08:15
lookatme I haven't seen bitmap in docs
TEttinger wander: what's the purpose you have in mind? I wonder if binding Roaring would make sense if you want compressed bitsets 08:16
Roaring is interesting among all the bitset libs out there because it has a not-super-tiny amount of overhead per bitset, but can compress large bitsets much better 08:17
lookatme Unfortunately, the for + start is the slowest in my pc, it took 45s 08:18
TEttinger EWAH, which is used in some form by Git, has much less overhead per bitset but less compression. I have some crazy code that uses a simpler version of EWAH's RLE-type encoding, but uses it for 2D data and can generally compress spatially nearby areas into one 16-bit "all on" section, and keep most of the rest in one or a few "all off" sections 08:19
08:24 domidumont joined
piojo @moritz, I don't think hyper even works right on my computer. it's much too fast, and I don't think the block even gets executed 08:25
wander I need a bitset to hold a state vector
piojo I assumed it was just an experimental API, but perhaps it's a windows problem

piojo because the bug I made such a careful testcase for is no longer happening with the newest build.
moritz then we should still have a test before we close the issue 10:01
just send a mail that the problem is fixed on newest rakudo
piojo oh, I need to reply to the auto-send, don't I?
moritz: I think this one would be hard to test for. My test case needs to be run repeatedly in a bash loop until it fails 10:02

piojo_ I can't comment very much because I haven't used any other web services framework 12:51
ZzZombo Can this be simplified? Need to return either a item type specific localized string, or from fallback object, or a decorated token as last resort.
return .value with ($localization{$item} && $localization{$item}{$type} && $localization{$item}{$type}{$note} || Nil,$localization{$type} && $localization{$type}{$note} || Nil).first({.defined && .isa(Grammar::VDF::Key-Value)});
"#$note";
12:51 wander joined, Actualeyes joined
piojo_ But I do like that it's synchronous, and it seems like most of the other modern web frameworks want to be async 12:51
wander . 12:52
ZzZombo I just noticed I can replace the argument to `first` with just `*.isa(Grammar::VDF::Key-Value)`, but anything else? 12:53
tyil cant you shorten the entire first part with the && to just the last one, and replace the || with // 12:56
so `$localization{$item} && $localization{$item}{$type} && $localization{$item}{$type}{$note} ||` becomes `$localization{$item}{$type}{$note} //` 12:57
ZzZombo no, if an intermediate element doesn't exist, accessing its contents is illegal.

ZzZombo it's not a Hash.
It's an instance of a custom class.
It just happens to do the magic necessary to make subscript access work with it. 12:59
tyil I wouldn't call it magic :p 13:00
moritz it's magic until you understand how it works :-)
13:01 ryn1x joined
ilmari what does it return for non-existing elements? why not just return something like Any, which itself returns Any on any subscripting 13:02
or you could make it return Nil 13:03
ZzZombo It returns Nil.
Maybe yea 13:04
ilmari well, Nil allows subscrpting and just returns Nil, so even the // is unnecessary 13:05
moritz the magic really happens when you start writing ot it
