Herby_ Evening, everyone! 00:21

Herby_ o/ 00:22
If I'm on Windows 10, and I want my Perl 6 to use winrar on a file, what's the best way to call it? 00:26
ZoffixWin Proc::Async? 00:27
docs.perl6.org/language/concurrency...3A%3AAsync 00:28
Herby_ Hadn't heard of that, I'll give it a shot 00:29
Also, I really enjoyed your recent Perl 6 presentation. Good job on it
00:30 tpa_ left
Herby_ Easy for a beginner to follow 00:30
ZoffixWin Thanks. 00:31
Herby_ Hmm. I copied that Proc::Async example and I'm receiving an error "no such file or directory... line 11". Looks like it breaks on the " await $promise" line 00:35
timotimo are you on windows? 00:36
Herby_ Yep, Windows 10
using the perl 6 MSI
timotimo you may have to find an absolute path to a .exe file
"echo" may not work at all; it may be a shell built-in, which we can't just execute like that from Proc::Async 00:37
00:38 addison left
Herby_ hmm 00:38
00:44 colomon joined 00:46 addison joined
Herby_ Yep, putting the full path to an .exe worked 00:47

[Coke] managed to screw up his IRC, whoops. 01:08
Herby_ what a headache...I can't figure out how to use Proc::Async to call an .exe that has a space in its path 01:12
timotimo isn't it enough to put that as the first string in the list of things? 01:13
Herby_ C:/Program Files/WinRAR/WinRAR.exe 01:14
Trying every variation
it keeps trying to open: Files/WinRAR/WinRAR.exe
timotimo show code? 01:15
Herby_ my $program = "C:/Program /Files/WinRAR/WinRAR.exe"; my $proc = Proc::Async.new($program);
my $program = "C:/Program Files/WinRAR/WinRAR.exe"; my $proc = Proc::Async.new($program);
geekosaur at a guess, it passes that to cmd.exe and you need something like 01:16
my $program = '"C:/Program Files/WinRAR/WinRAR.exe"'; my $proc = Proc::Async.new($program);
Herby_ no such file or directory
but I can copy that path directly into the cmd prompt and it launches WinRAR just fine 01:17
timotimo perhaps you have to put a "\\" in there in front of the " "? 01:19
oh, oh, oh
what about [$program] ?
oh, no, it's *@args
so it wouldn't try to split on whitespace for you if there's only one argument 01:20
01:20 addison joined
timotimo my $program = '"C:/Program\\ Files/WinRAR/WinRAR.exe"'; my $proc = Proc::Async.new($program); 01:20
i'm going to bed now, sorry
Herby_ no such file or directory 01:21
thanks for the try. have a good night

ZoffixWin Herby_, are you sure you actually have WinRAR at that location? This works fine for me on Win7: perl6 -e "await Proc::Async.new('C:\Program Files\7-Zip\7zFM.exe 01:35
').start"
(minus the spurious newline)
Herby_ if I type in: ""C:/Program Files/WinRAR/WinRAR.exe" at the command line, WinRAR launches 01:37
if I do: perl6 -e "await Proc::Async.new('C:/Program Files/WinRAR/WinRAR.exe').start"
I receive an error "Cannot open Files/WinRAR/WinRAR.exe" 01:38
ignore the extra quotation on the first line
On Windows 10
if I use backslashes instead of forward slashes, I get the same error 01:39
ZoffixWin Well, then the problem is obvious.... 01:40
Windows 10 sucks :D
Herby_ Windows is the devil?
hah
01:40 addison left, addison joined
Herby_ I guess I could copy the executable to a path that doesn't have spaces 01:41

01:45 mohae left
Herby_ perl6 -e "await Proc::Async.new('C:\Program Files (x86)\Battle.net\Battle.net.exe').start" launches the executable just fine 01:45
I'm missing something simple here
01:46 mohae joined
ZoffixWin :S 01:48
Herby_ your example works fine on multiple executables, some even in the same directory 01:50
but it does not like WinRAR
ZoffixWin (installed WinRar) FWIW, I get the same error as you, on Win7
Herby_ Maybe WinRAR offended Perl 6 in another life, so they want nothing to do with each other 01:51
ZoffixWin It might be an error generated by WinRAR.. Calling perl6 -e "await Proc::Async.new('C:/Program Files/WinRAR/WinRAR.exe', 'foo').start" doesn't give that error
Herby_ good to know you're getting the same error and I'm not crazy
01:53 zhida joined
Herby_ yeah, i'm seeing the same. when I pass it some arguements, it doesn't error but it doesn't seem to do anything 01:57
b2gills
.oO( doesn't 7zip work with rar files? )
 01:59
ZoffixWin Seems like you should be using C:/Program Files/WinRAR/UnRAR.exe instead.
b2gills, it does
Herby_, it takes 'e' and filename as arguments to extract an archive and it works on command line, but fails with Perl 6 with "The spawned process exited unsuccessfully (exit code: 7)" and I've no idea why :S 02:00
Windows is stupid
02:00 zhida left
Herby_ yes is. I'll skip that part of my little program for now 02:00
thanks for testing it for me
b2gills could it be that Winrar doesn't like being a subprocess? 02:01

shinobi-cl is there a way to code my own adverb? i want to use :exists for my own class 03:25
03:27 Vlavv_ left, Herby_ left
shinobi-cl basically, it is a "matrix" class, with rows and columns. When i do $m.get-cell(3,3) and this position is beyond bounds, it is returning Nil. And using $m.get-cell(3,3):exists complains because i apply :exists on a Nil 03:28
Nevermind, found it ... so is just like a parameter.. 03:29

ufobat does anyone have an opinion on that: github.com/tadzik/Bailador/issues/55 ? 09:46
masak ufobat: `return True session<is_logged_in>;` -- two terms in a row. missing an `if` there? 09:49
ufobat: `$route->append_route` -- accidental Perl 5 syntax. did you mean `$route.append_route` ? 09:50
ufobat 2 times aye!
masak I would suggest looking a lot at prior art for this one 09:51
AFAIK, both Mojo and Catalyst solve this in some way
ufobat my suggestion is quite mojo like 09:52
DrForr Dancer solves that through application hooks, because at least what I'm seeing there looks like authentication.
ufobat i just find the naming in mojo strange, there is for example a "under" which is not much related to "over", but the "group" is similar to under 09:53
DrForr And keep in mind that Bailador is modeled on Dancer, so looking to Mojo/Cat for inspiration may not be the right place to look.
ufobat its just my excample that is about authentication, its basically a "route under contition". and your point is valid, of course. I also wanted to know if bailador is staying a dancer clone or should it be developed on its own / pick good ideas from somewhere else 09:57
DrForr Requiring 'response_content = ...' makes using handlers much more awkward IMO as well. Prancer just uses a dynamic variable for content-type, headers and such. 09:58
ufobat github.com/tadzik/Bailador/commit/...5036d488c7
oh! thats a cool idea! 09:59
thats something i dont like curently. that you export methods wheres some can only be called outside of the route code, and others only inside of the route code 10:00
having it as dynamic variables you might reduce this "problem" a bit
Thanks so far! :-)) 10:01
DrForr Just removing the "a port of Dancer" doesn't mean that the code is suddenly laid out like Mojo :)
ufobat haha! right. i dont know it either, 10:02
DrForr Not saying that you shouldn't use Mojo as a model, just saying that the model may need to be changed. 10:03
ufobat i am not perfectly sure if that is the example I disliked a few days ago, at least it's quite similar... metacpan.org/pod/Dancer2::Tutorial...HTTP-verbs look at the code exampel in the section 10:04
to my understanding here this requires that you check if you are logged in in each route 10:05
and again this is basically not about authentication, its about "routes under conditions"
or metacpan.org/pod/Dancer2::Plugin::Auth::Tiny 10:06
DrForr Right, I'm just saying that the most common case is authentication.
ufobat yeah, i agree!
DrForr Which is why Dancer uses a more generic hook mechanism. I've worked recently with fixing authentication in a Dancer app and am not quite convinced that hooks are the solution, so I'm somewhat on your side here. 10:08
10:08 ocbtec joined
ufobat mojo uses events, i assume that those events are somehow similar to the hooks. i will read some documentation on it 10:12
DrForr I haven't thought about it too much because I wanted to get more experience with how Dancer does that, but in the current Dancer app I'm working on I'm 98% confident that the people who wrote the original went as far as running the Dancer build tool and then just started writing. 10:13
ufobat ah! maybe! tadzik accepting gabors PR on changing the readme might be a sign that its not ment to be a pure dancer clone ;p
i dont know a "dancer build tool"? 10:16
DrForr I might be thinking of Cat actually. 10:17
ufobat what is (or should) prancer be? the name strongly reminds on dancer 10:20
is it a clone (as well)?
DrForr Not a clone. 10:22

ZoffixWin :)
timotimo The objective of this endpoint is to unlock the significant public investment in earth observation data.
Sound exists in space. Sometimes. And NASA has released a series of space sounds via sound cloud. We have abstracted away some of the hassle in accessing these sounds, so that developers can play with the audio files. For example, a useful application would be an automatic filter to identify human voices in these audio files. For now, that would help identify content. Later, however, when we retrieve sounds 10:46
from far-off planets, we can apply the filter to identify unknown human space colonies. That was a joke. Sort of.

ZoffixW stmuk, it's been many moons and many beers since I last looked at that codebase. If you see a better way to do thing, sure implement them. I kinda gave up on that code base when we decided there'll be MetaCPAN6/PAUSE6 stuff that'll replace the current system. 13:39
Begi "there'll be MetaCPAN6/PAUSE6 stuff that'll replace the current system." 13:40
-> when ?
ZoffixW Begi, well, you can already upload P6 modules to PAUSE. jdv79++ and others done some preliminary works on converting MetaCPAN into a P6-friendly version. That was about 4 months ago and I haven't been following the project. 13:41
stmuk I think github.com/perl6modules/perl6-module-uploader is ran occasionally which populates www.cpan.org/authors/id/P/PS/PSIXDISTS/Perl6/ 13:43
its a nice effort but I don't really see how the old CPAN could fit with the new 13:44

stmuk ZoffixW: I suspect modules.perl6.org isn't likely to go away anytime soon 13:45

ZoffixW Yeah, the fact that two authors can have a module with exactly the same name complicates things. 13:45

MadcapJake So, will Meta::CPAN gain a perl 6 selector or will we just have to figure that out for ourselves? o_O 13:47
ZoffixW MadcapJake, it'll be a separate site. We'll just use their codebase as a starting point instead of starting entirely from scratch. 13:48

MadcapJake stmuk: yeah it's early alpha for sure, but still it's such a cool idea, no need for mirrors or any centralized resources! 13:59
jamesneko It dies with an error if you ask for too much data in one go. But I was kinda surprised at this, since the documentation doesn't mention that. I've since realised that okay, it must be wrapping C's read() call, and that's limited to SSIZE_MAX. But how do I find out what that is from Perl? 14:00
gfldex jamesneko: you don't. Please file a rakudobug.
jnthn What's the error? 14:01
jamesneko I mean, if I were doing C programming, then sure, I can't expect arbitrarily large buffers to be returned. I kind of figured Perl's read would do any amount of looping necessary and return a Buf the size I wanted. 14:02
14:02 fireartist left
jamesneko okay, sure, how do I file a bug for rakudo? Or perhaps it's a documentation bug? 14:02

s/you're/your/ 14:58
diakopter perlpilot: good luck with what? I wasn't volunteering
nine diakopter: are those hundreds of reasons listed somewhere? Sounds like too much to paste into the channel.
[Coke] Ulti: that glot website is a security hack waiting to happen.
diakopter nine: there have been untold hours spent debating this already on this channel and mailing lists over the last decade
nine: you can search the logs if you care at all, but I'm guessing you don't 14:59
perlpilot and none of that discussion has resulted in a change away from RT
diakopter (I wouldn't care either)
nine And no one bothered to at least collect these "hundreds" of reasons for review? But others are expected to do the real work of migrating?
MadcapJake diakopter: this has all been discussed on perl6/user-experience repo, the general consensus is (1) RT works fine and most complains are really just minor annoyances, (2) NO ONE wants to do the work of migrating, and (3) GitHub Issues aren't anything special (and I would argue that's still the case even with the recent upgrades)
diakopter MadcapJake: as I wrote here the other day, I read that thread, and we already talked about it 15:00
Juerd I really dislike RT and wouldn't mind doing migration work. The thing is, such a migration will always be lossy because you can't make people have accounts on both systems. 15:01
perlpilot Juerd: loss is a feature of the migration ;)
Juerd (And of course, things like Github won't allow you to post on behalf of someone else)
diakopter who doesn't have a github account [besides nwc]?
perlpilot somewhere there is a script that will automatically migrate from RT to github. It's all of the social implications that are the problem. 15:02
Juerd And I don't really understand why migration would be necessary. RT could be used for everything that's already in there, and something else for new issues.
diakopter Juerd: I completely agree with that
Juerd++ 15:03
MadcapJake diakopter: I'm personally not in favor of tying Perl 6 issues to something that has no migration path OUT (or IN for that matter), what if GH decides to become a SourceForge down the road?
perlpilot wanders off after realizing this discussion has happened before
nine The Parrot project successfully invested lots of time in moving from RT to GH issues. Obviously time well spent.
diakopter heh
MadcapJake ok, I guess IN is covered at least :P
Juerd MadcapJake: It's not as if we can be certain that rt.perl.org will stay with us forever. 15:04
MadcapJake Juerd: at least it's tied to Perl Foundation rather than some for-profit company
Juerd Tied?
15:04 domidumont joined
MadcapJake perl.org 15:04
diakopter somehow I think github, with probably 100,000x the users and activity levels of perl.org, will last longer.
MadcapJake diakopter: I'm guessing everyone said that about SF back in the day
Juerd RT's development is tied more to Best Practical, a for-profit company, than to TPF, and if development halts we're stuck anyway. 15:05
MadcapJake RT is written by BestPractical, not hosted by them
They can't change our version because TPF is running it, not BestPractical, we only upgrade if we want to
diakopter we?! 15:06
MadcapJake well, that's a really loose 'we'
Juerd "This service is sponsored and maintained by Best Practical Solutions and runs on Perl.org infrastructure."
diakopter yes, sponsored and maintained
MadcapJake Juerd: keyw words: "runs on"
Juerd Still we depend on BP for RT to continue to run well 15:07
MadcapJake Ok, so let's say that it's just as bad, why would moving to GH be *better*?
Juerd I don't mind that, by the way.
MadcapJake: I'm saying that as for depending on a single company, it's on par, not better or worse.
diakopter MadcapJake: do you know how many users Github has?
MadcapJake Juerd: that's fair 15:08
diakopter: that's really not what I'm talking about
diakopter why not?
MadcapJake diakopter: because I am discussing corporate ties not user base
If any migration path is done, it should be a move closer to in-house rather than the same level or worse (which I would say GH would be worse, in terms of tying to some for-profit) 15:09
diakopter wtf. there's no "in-house"
Juerd Unless we dogfood an issue tracker :) 15:10
diakopter perl.org is donated by other companies
MadcapJake diakopter: I'm speaking in terms of some hosting that we manage and maintain
diakopter the servers and admin time
nine The big difference is that with perl.org infrastructure we will always be able to at least get our data out. With GitHub we could be locked out any day. The most probable cause would be someone simply buying GH and changing business strategy.
Juerd nine: This is a matter of scraping and making backups, really.
MadcapJake nine++ # that's exactly what I've been trying to articulate
nine Code maintenance is completely orthogonal. And really, you don't need much maintenance to keep RT running over a couple of years of migration period.
MadcapJake Juerd: well make sure you right that scraper, then maybe the case could be made to switch :P oh and make sure you scrape it before you can't anymore, and make sure you update the scraper every time they change their frontend 15:11
s/right/write/ :P
Juerd MadcapJake: github.com/joeyh/github-backup
MadcapJake: First hit in google for 'github backup' :) 15:12
As for frontend... they apparently have an API
diakopter total idiocy. losing data to perl.org or RT is astronomically far more likely
Juerd I think both are quite unlikely.
MadcapJake Juerd: hosted on GH, and how is it implemented? does it gather issues (the only thing we need) 15:13
nine diakopter: throwing words like "idiocy" into a discussion usually helps your cause a lot
Juerd MadcapJake: I don't see the point in answering these questions if the decision has been made and you have made up your mind. 15:14
diakopter how else do I name-call something that truly is an argument from ignorance.
Juerd MadcapJake: I was just pointing out some flaws in the general consensus you summarized. It was not my intention to restart the entire discussion. That happened anyway, and I'll refrain from further participation because it's a waste of everyone's energy. 15:15
MadcapJake Juerd: I'm not trying to be rude, it's just, I don't really feel that a scraper is the best security
Juerd It's like the name "Perl 6". I disagree strongly, but making the decision isn't up to me. I don't like having the discussion over and over just because I happen to still disagree with decisions made. 15:16
MadcapJake Juerd: there was certainly more to it than that, I've just tried to boil it down to some major points (I feel I've posted that in here a few times and most of them with diakopter)
Juerd That's okay. I don't mind to just disagree and leave it at that :) 15:17
diakopter forget it, no one regularly reviews the bug reports anyway with any frequency (Coke and jnthn review them thoroughly every year or two) 15:18

nine diakopter: Exactly. I'd consider going through the tickets we have and closing off the useless ones time much better spent than migrating to another tool. And it would help with some usability issues. And might even make a migration easier... 15:21
Juerd diakopter: The majority of bug reports are auto generated from failing tests :|
[Coke] I'm seeing a lot of not-quite-true facts going by. :) 15:22
diakopter miracle of miracles, I was able to log in to bitcard
nine Back to: Code ref name '' sf cuuid (1) sf name '' sf dep idx 1 sf sc idx 16 sf cu from '' does not exist in serialization context 15:23
[Coke] I don't think tons of tickets are fixed already. if there's code, it's probably been reproduced. Most of the "useless" tickets have been closed - the majority of RTs are not auto generated (there are a huge number of these which are indirectly my fault - but they are tied to roast, and while they're in roast, they need to be dealt with one way or another)
Juerd Then I misremembered that. But I recall going through pages and pages of autogenerated reports. 15:24
[Coke] yup. all stuff which needs to be dealt with because of the stuff in roast. 15:26
If folks want to help out with bugs, I have a gist somewhere with concrete stuff that's doable, one sec.
Juerd Still, though... 914 "new" bugs and 394 "open" in a single queue with no organization other than some tags in subjects. It's tough to get an overview of the situation. 15:27
[Coke] gist.github.com/coke/ac078396e8f216b83e9a had some pointers, and could probably be updated with more stuff in a post-xmas world. 15:28
Juerd: sure is. If anyone would like to carve out some tickets to work on, I'm happy to help them find some.
nine Juerd: I don't understand why we're using only a single queue anyway.
[Coke] just added "Open vs. New RTs" to that gist. 15:30

ZoffixW stmuk, probably can just fix it on this line. Set it to 'N/A' if it's zero instead of piping all values through strftime: github.com/perl6/modules.perl6.org...oot.pm#L28 16:14

but it probably comes back from the DB as 1970... 16:17
ZoffixW Nah. It's epoch. And I believe it would be zero in this case. 16:18

hoelzro that's quite odd

MadcapJake psch: so how come when I edit the files in sources, it still impacts the running of scripts?
psch MadcapJake: because it sees that the source file has a newer timestamp and re-precompiles
skids Timestamps get checked, recompilation happens.

grondilu TimToady added that syntax some time ago. 20:51
MadcapJake AlexDaniel: fixing now, thanks!
psch a Hash of Hash that takes Int as key where the values are Hashes that take Int as key..?
grondilu I would have sweared the deep typing used to work.
psch: yes 20:52
I basically want a data structure indexed by two integers. But I don't want an array for some reason.
20:53 skids left
grondilu one of the reason is that my keys will be very sparse. Like there is data for 10 and data for 2**32 but nothing in between. 20:53
so I really want a hash. 20:54
MadcapJake what's the inner hash for? 20:55
regular hashy data? :)
AlexDaniel MadcapJake: here too: > "$path/META6.json"
grondilu same kind
MadcapJake grondilu: maybe more of a linked list then? 20:57
AlexDaniel: thanks
grondilu a linked list would be a hassle to modify.
but it would indeed be the most efficient.
Imagine an infinite 2D grid. On each point of the grid, I can place an arbitrary number of stones. I want a data structure to store any possible ways of putting a finite number of stones on the grid. 20:59
so the first key is the X position, the second is the Y position, and the value is the number of stones. 21:00
Basically I want a data structure for what physicists call a field.
(a discrete one, though) 21:01
AlexDaniel MadcapJake: in the example above I wrote ｢mkdir -- "…"｣, and ‘--’ is there for a reason. Not sure if you really want to get this script that right, but I'd mention it anyway. If you're passing some arbitrary variable (like a filename) as an argument to some command, then bad things can happen if this variable starts with a dash. That's why most commands support -- as in “okay, no more options are going to be passed after this, tre
everything as plain strings”
MadcapJake: a quick way to see that in action is ｢x='-n'; echo "$x"｣
that is, ｢git init -q -- "$path"｣, ｢touch -- "$path/lib/$name.pm6"｣, etc 21:03

grondilu I guess I could create a Point class with an appropriate WHICH method. 21:05
MadcapJake AlexDaniel: thanks! my shell-fu is minimal at best :)
grondilu but I would prefer using multiple shapes, frankly. 21:06
it's less verbose.
psch grondilu: ...patches welcome? ;) 21:09
MadcapJake grondilu: your subs may end up carrying some of that complexity that a Point class could hide (though it really depends on what you are planning on doing with the data)
psch grondilu: the error message seems to suggest what you want should work
grondilu: it just seems no one got around to make it work yet
AlexDaniel MadcapJake: if you are interested in improving your shell-fu, then this is one of the fastests ways that I know: mywiki.wooledge.org/BashPitfalls . Just go through the list one by one and that's it. Most of this stuff applies to other fancy shells like fish 21:10
psch i'm not sure what would make a field discrete, though
hmm, representing what wikipedia describes as a field does seem kinda hard-ish 21:11
AlexDaniel MadcapJake: in fact, shell-fu of fish developers is kinda weak too… At some point I heard about fish, went to their website and found some example with unquoted variables
MadcapJake: so I joined their irc channel and was like “oh guys! Fish autoquotes everything? THAT'S AWESOME!!”
MadcapJake: and then I just figured out that their examples are all wrong

21:20 sufrostico joined
jnthn So yeah, you'd need something that is 21:20
grondilu I feel we already had this conversation. I was wondering why there is not a true 'Tuple' type, that is like a list but a value type. I forgot the explanation you gave me. 21:21
jnthn Well, the history on it is that when we had Parcel *and* List, Parcel played that role 21:22
And nothing really took it up again after the GLR
The reason *Array* can't be is very clear though: it's mutable
AlexDaniel MadcapJake: their examples are still expecting that files do no start with dashes, so it's still wrong… but at least quoting issues are fixed by using some magic? 21:23
grondilu I agree Array can't play that role. But the lack of a tuple seems LTA
AlexDaniel MadcapJake: so maybe your gist does not need all these quotes, I'm not sure now. Maybe I was wrong because my information is outdated
MadcapJake AlexDaniel: no idea :P but it did work before 21:24
jnthn Well, the name Tuple is still free... :) I'd not be against some solution for this, but I'm not surprised we didn't find time for it between the GLR landing and Christmas :)
grondilu between this and multiple shapes, I'd rather have multiple shapes though. 21:25

AlexDaniel Xliff_: any infix op has …= form
Xliff_: even your custom ops

Xliff_ I confused "m:" with the first "my" ... I am having a great time tonight!!
I should get beer so at least I have an excuse! :P
AlexDaniel: I see.

Xliff_ LOL
So not any infix....

AlexDaniel Xliff_: also note that . (as in a method call) can also be used as an infix op 23:51
m: my $x = 41.9; $x = $x.round; say $x
camelia rakudo-moar 61d231: OUTPUT«42␤»
AlexDaniel which means that we can have some spaces in there
m: my $x = 41.9; $x = $x . round; say $x
camelia rakudo-moar 61d231: OUTPUT«42␤»
AlexDaniel and it also means that we can use .= 23:52
m: my $x = 41.9; $x .= round; say $x
camelia rakudo-moar 61d231: OUTPUT«42␤»
AlexDaniel though I have no idea how it works underneath… “magic”, I guess. But at least it feels consistent 23:53
Xliff_ Heh! 23:55
Is there any way I can form a substitute regexp without having to quote angle brackets?
Ack! Dumb question. nevermind.
(Really should get that beer, now)
Juerd AlexDaniel: Magic? Fiddly, at least: 23:56

AlexDaniel C++ what?
Juerd AlexDaniel: It's recognizing "new R" before anything else
That's C++-style object construction 23:58
AlexDaniel
.oO( Unsupported use of Pyth constructor syntax; … )
Juerd Just like how for (a;b;c) is called "C-style for"
In fact, 23:59
m: for (;;) { }
