stmuk I think a vocal minority of the community are stuck in the early 2000s and scared of change and learning new things. Our energies might be better used in addressing the wider programming community with "look how cool this is" type posts 11:51
gfldex Python 1.0 was released in 1991 and was useless. Python 2.0 was released in 2000 and the first useable release. It took years after that to be used in production. So we are well on track if you ask me. 11:52

bioexpress Hello, "print-table" (github.com/kuerbis/Term-TablePrint-p6) prints $table (list of lists) on the terminal. The option "max-rows" limits the output to max-rows table rows of $table. I am considering to remove this option - my thoughts: if the user passed $table to print, then that should be OK. Does somebody encourage me to remove "max-row" or does somebody think that I should keep this option?

MasterDuke timotimo: how much memory growth did you see with (i think it was Ulti's) MQTT::Client test script? 13:45
timotimo i changed it to read every message there is and it didn't grow terribly much (i looked at rss growth with snapper)
but at some point it would just stop receiving more and i haven't looked into that yet 13:46
MasterDuke after how long? i ran it for a couple hours and mem started at ~150m and ended at ~200m, but was still receiving messages? 13:47
s/\?$//
timotimo you're running the script unmodified? 13:48
MasterDuke yeah
timotimo that'll run for longer, yes 13:49
MasterDuke you added a `whenever $m.subscribe("#") { ... }`? 13:50
timotimo abrtd is consuming 100% of one core right now :\
yeah, that's what i had 13:51
it has more growth towards the beginning, which is likely moarvm's diverse kinds of caches filling up slowly 13:52

Juerd This is Rakudo version 2017.10-4-g4fca94743 built on MoarVM version 2017.10
Er 14:24
MasterDuke how do you get your rakudo?
Juerd This means my rakudobrew hasn't been updating the binary and I've been updating weekly for no reason. I never checked to see if I actually got the new version :) 14:25
I'll rm -rf ~/.rakudobrew and try if recent improvements have fixed the issue 14:26
geekosaur heheh
MasterDuke ha. i'd be curious to see if you get the same rate of leak with something newer
geekosaur that happens sometimes... but I bet that's the nom change
(it's master now)

MasterDuke yeah, that has bitten a bunch of people 14:26
AlexDaniel I'd expect the most recent rakudo version to leak more 14:32
at least, that's what I'm hoping for
uh… that sounded wrong
El_Che markong: no, you can buy the book everywhere and the drm-infested ebook on several places. They just don't sell ebooks anymore 14:33

markong El_Che: right, that's exactly the problem: I can only buy the paper book to *buy* a book (in 2018)! after years of anti-DRM ebook campaigning, o'reilly has finally took off his mask, showing that the bottom line is what count! What they don't understand is that they aren't renting multimedia contents (they have been infested by the netflix virus and joined the band-wagon business model of flat subscription) and that technical manuals are an entirely different 15:37
thing! That's incredible, since it once *was* a technical book publisher and was good at it!
also it is not true that you can buy digital copies: support.oreilly.com/oreilly/topics/...pdf-ebooks they just want you to get something off amazon on your kindle! that's it!
I've always been happy to buy on their shop (Perl related content and other) because of the DRM policy; now no more! 15:38
coincidentally a lot of Perl related literature is published by them: I hope authors and the "community" at large try to pull old content out of there, if that's possible, and surely start to push for publish anything new on other platforms (dunno maybe manning.com) 15:39
at least manning is still making available drm free digital copies (PDF included) and by the rate of publications seems that it is NOT the problem! 15:40

markong I understand your situation: that's a shame! Shame on o'reilly! I've personally rewarded them with paper book purchases, after having owned digital copies for a while (legal and illegal). Now no more: I won't buy anything published by them! The PDF killing is outrageous: They simply aren't considering that their audience is not the same as netflix's ! go figure their state of mind! 15:52
15:55 Kaiepi joined
markong the digital (PDF) format is simply the de-facto format for anything technical (academia papers/ manuals / technical books). e.g. I have a "Programming Perl" paper edition standing on my desk, and a legitimate PDF edition...I very often find myself go to the index to look up something while coding, and even more often, doing a search on the PDF edition give me the exact info bit I'm looking for in a third of time compared to the paper one 15:56
15:59 setty1 joined, zakharyas joined
markong El_Che: Yes, there are many alternative literature sources on the net nowadays, but (!) books still have more quality and usually, if well written, are a good source of information for a vast audience. e.g.: I can go down the docs perl6.org to start learning perl6, but I would enjoy to read the "Learning Perl 5" equivalent for the version "6" of the language! having published materials on a topic has enormous benefits on its acceptance (talking about 16:02
programming languages)

camelia Too many positionals passed; expected 2 arguments but got 4
in block <unit> at <tmp> line 1
moritz map doesn't take more positional arguments
chakli It took 2 from my 1st example 19:12
moritz no
the block that you gave to map took two arguments
chakli it did 1+2, 3+4 ...
moritz m: say (1..8).map(-> $a, $b { $a + $b })
camelia (3 7 11 15)
timotimo you need to either pass a little closure or curry in the arguments with the .assuming method
actually 19:13
moritz chakli: what do you want it to do?
timotimo i think what you really want here is (1..8 X 2).race.map(&addn)
moritz m: sub addn($n1, $n2){say $n1+$n2;}; (1..8).map({ addn($_, 2)})

chakli Is it safe to pass a sqlite statement into race.map()? or would i need a mutex (or something like that)?
timotimo sqlite.org/threadsafe.html 19:24
by default it will lock for you so no two threads do something in the database at once, and so it doesn't explode
so using sqlite in a race will not break, but it will only be slightly faster 19:25
it'll be able to compensate for a little bit of perl6's own overhead 19:28
chakli Thanks, I was not sure about the DBIish part of it. My bottleneck is network. was trying to parallelize it 19:29
Xliff_ <Xliff_> If I wanted to make an app that had net portion in the background, I would need a Promise and a Supply, right? 19:30
Promises and Supplys being the areas of P6 I have deliberately not yet explored.
19:31 trnh left
timotimo both are helpful for that 19:31
if you only deal with a single connection at a time, you'll be fine without supplies, too, but they make some things easier to code as well
19:36 quotable6 joined, ChanServ sets mode: +v quotable6
Xliff_ Yeah. Single connection at a time, I think. 19:38
But net code must be in the background. Asynchronous handling.
timotimo right, so you'll just start { } a task that handles the connection for you 19:41
moritz it really depends on what you want to do
if all you want is a single result asynchronously, a Promise is enough
Xliff_ k
timotimo right, with the task started off in the background you'll probably still want to communicate results/events to the main code 19:42
Xliff_ start {} returns a Promise, right?
And the best way to get data from a Promise into the main code is a Supply?
19:43 sftp left
timotimo nah, i'd do that with a channel. if it's just a single result, let the start block return it (but not with "return", just let it be the last statement) 19:43
Xliff_ Erm. Won't I need the Promise from the start block? 19:44
timotimo for many supply situations the thread that emits the value will pay the cost of handling teh results
19:44 sftp joined
timotimo well, depends on whether there's just one result value that falls out at the very end 19:44
in that case you can just have the promise carry the value
Xliff_ Well, the net code will need to be a loop.
net code will listen for connections in the background (Promise) for data transmitted from another client (Supply) 19:45
At least, that's the thinking.
timotimo have my rsi break coming up
Xliff_ OK.
Even if that method is overthinking, as long as its on the right track it will help. 19:46
Will have to read up on Channel
timotimo if you use async sockets you'll get a supply of connections from listening on a port
Xliff_ kk 19:47
timotimo you can then either "start" a task per connection or handle all connections with a single react or supply block, they'll be contending over a lock to run code inside any whenever blocks so accesses to lexicals in and around the react/supply block are safe

Xliff_ will a react {} block always stay in place, or do I need to surround it with a loop? 21:07
timotimo the react block will be exited when all whenevers are done, when an unhandled exception occurs, or when "done" is called 21:09
there may be more ways to do it
Xliff_ OK, so loop necessary.
geekosaur that is not how I understood what timotimo said? 21:10
Xliff_ Because each time a message is received, we will close the socket and then listen again for another connection.
timotimo but the whenever on the listening socket should be in the react to begin with
Xliff_ Yes.
timotimo so that whenever will be left when there's some kind of I/O error on the listen socket
21:10 trnh left
timotimo i'm not sure i had that happen yet 21:10
Xliff_ But if the listen socket is closed by the client? 21:11
timotimo that's not something a client can do
Xliff_ my $socket = IO::Socket::Async.bind-udp('localhost', 3333); 21:12
react { whenever $socket.Supply -> $v { ... # DO SOMETHING! } }
timotimo oh, udp!
Xliff_ So the whenever is still in place?
timotimo well, that's another matter entirely
Xliff_ LOL
timotimo because udp doesn't have connections, so a "listen socket" isn't the same as in tcp
where a listen socket will give you new sockets that represent connections that came in from others
21:13 yoleaux joined, ChanServ sets mode: +v yoleaux
timotimo whereas with udp a "connection" doesn't exist per se and you just get all messages that are aimed at a given port 21:13
given ip *and* port
Xliff_ Yes. UDP is for handshake. TCP is for communication
timotimo but even then, that whenever will stay in place as long as you don't "last" the whenever it works with (or exit out in other ways) 21:14
b2gills dmaestro: I would try `use v6;␤unit class Shared::Extra;␤use Shared::Thing;␤also is Shared::Thing;␤…`

b2gills I gathered that much, I was just pointing out something else that might be more to his liking 21:15

comborico1611 Can someone paraphrase this for me? "The type of a variable holding a value is correlated to its value." 21:55
DrForr Seems to me to be a bit of a bass-ackwards statement. 21:56
21:56 Kaiepi left
comborico1611 This comes after, "The type of a strongly declared empty variable is the type with which it was declared." 21:57
21:57 Kaiepi joined
DrForr Is this something you're writing? It feels very circular to me. 21:58
geekosaur if you declare a variable as holding a Cool, then its type when empty is Cool; if you put an Int in it, then its type is Int.
gfldex Sounds to me as someobody tries to shoehorn abstraction into something that is acually quite real
comborico1611 Heh. It's perl6intro.com/
geekosaur basically that sounds like a terrible way of a variable can hold any type which is a subclass of its declared type 21:59
comborico1611 Section 3.5 Introspection
geekosaur *can hold a value of any type
*a terrible way of saying that
how did I mangle that so badly? maybe you were better off with the original, it at least had all the words >.>

gfldex or in other words: "Perl 6 containers are hard‼" 21:59
22:00 ChoHag joined, mtj_ joined
gfldex The whole section is a terrible mixup of values, typeobjects, containers and variables 22:01
DrForr Sounds like someone posing a 17th century philosopher in front of a pony, in other words putting Descartes before the horse.
gfldex but then again, containers may just be a bit to hard to fit into an intro to a language
comborico1611 I see. 22:02
DrForr Yeah, that's a bit too advanced of a concept for an intro, I think.
Easier to just explain 'my $variable" can hold variables of any type, and if you want to constrain the type, you can say 'my Type $variable' 22:03
comborico1611 Should we submit a report? 22:04
DrForr Feel free... I'm not sure who owns perl6intro. 22:05
comborico1611 Ahh. I see.
Thanks for the help, fellas! 22:06
Glad to see I'm not the only one mixed-up with that.
