sorear Juerd: still ddosing? 00:13
00:14 sftp left, sftp joined
Juerd sorear: No, it has nothing to do with attacks of any kind, as far as we can tell. 00:19
One cable's link is disappearing at seemingly random intervals; every time it takes a litlte over 30 seconds for the link to reestablish due to STP. 00:20
benabik Is there a good reference for "what is 6model"? 00:21
Juerd It happens 1 to 4 times per hour. Hasn't happened for the past 30 minutes.
sorear STP?
Juerd Spanning Tree Protocol; prevents switch loops in large networks.
sorear whyyyy 00:22
redundancy is the best part of the internet
Juerd It's a feature that every managed switch has.
benabik sorear: It's a side effect of redundancy. You need to make sure two switches don't both see the other as the best route to somewhere.
Redunancy good, loops bad.
Juerd Because without it, you'd get loops. Loops lead to broadcast storms, and those kill switches. 00:23
While port bonding/trunking exists to combine two ports, it's not typically seen as a redundancy thing, and it's not enabled by default, or even discoverable in most cases. 00:24
So if there are two links between switches, it won't see that as a spare link, or to increase bandwidth. Instead, STP will kick in and decide which one to disable. 00:25
lichtkind greetings Juerd
Juerd STP has a learning state of approximately 30 seconds before it enters what's called forwarding state. Forwarding state is the normal state for switch ports.
Cheap switches forward immediately. 00:26
STP can be disabled per port but that's dangerous.
If these issues continue we'll have to do so, though.

Juerd Well, I guess it wasn't the switch port either then :( 00:30
00:30 PerlJam joined
Juerd That was another 30 second outage... 00:30

benabik Bad NIC? 00:31
benabik knocks on wood.
geekosaur ...nic-noc jokes? 00:38
Juerd benabik: No, the flapping connection is definitely between two switches 00:44
One of those is ours. The other one isn't. These are located at an internet exchange.
benabik Oh well that's... better? Harder to fix, but hopefully doesn't require new hardware... :-/ 00:45
Juerd Well, we first have to find out what the hell is going on.
But now I'm going back home. I've enabled STP PortFast so that it will skip the 30 second learning phase. 00:46
00:46 plobsing joined
Juerd That should bring the outages down to 4 to 5 seconds only and is probably much more bearable. 00:46
benabik Yay bandaids!
Juerd++
Juerd Yea.. :(
I hate leaving this place (extremely noisy datacentre-like room) without a real fix. 00:48
This is a marvellous place. Without leaving the room I could kill of a good part of the Dutch and probably European internet just by cutting cables until the security guys arrive. I just wish fixing things was as easy as breaking them :) 00:50
benabik I get that feeling every time I walk into the machine room at school... Although I can only really screw up one building from there.
Juerd Oh well, at least we've tried a few solutions; theoretically that means we're closer to knowing what the problem is.

benabik "On the contrary, I've learned a great many things that won't work."
Or however that quote goes.

p6eval rakudo 984dc7: OUTPUT«False␤»
sisar r: say 5 ~~ Int ;
p6eval rakudo 984dc7: OUTPUT«True␤»
sisar is 'int' incorrect? Data types _have_ to start with an uppercase letter ? 02:04
benabik int is a native type
Native types are lowercase. (int, num, str)
sisar what's a *native* type ? 02:05
benabik Ints are variable precision, ints are limited to whatever the (virtual) machine does by default.
However ints are likely to be faster.
sisar um, so why did 5 ~~ int fail ? 02:06
i mean, give False
jnthn Something forced it to box. 02:07
(The 5)
At which point it becomes an Int
sorear ~~ int feels wrong to me
sisar jnthn: 'to box' ? 02:08
jnthn sorear: Wrong in the sense of "hard to think of a sane model where it works"? :)
sisar i'm unfaniliar with the term
Teratogen can you do stuff like char broiled; in Perl 6?
jnthn sisar: Turning a native type into an object
sorear jnthn: wrong in the sense of "~~ takes Mu, so it will never ever see an int argument" 02:10

fglock I was reading trac.parrot.org/parrot/wiki/Languages, and went to check Blizkost - I wonder if it makes sense to compile perlito5 to parrot (Blitzkost seems to be just a perl wrapper) 12:56
*Blizkost 12:57
moritz you mean as a way to interop between p5 and parrot?
that does make some sense, yes 12:59
fglock no, not as a way to interop, but as an actual implementation of perl5 in parrot 13:08
moritz ah, ponie 2.0
so, what would you emit? PIR? winxed? 13:10

fglock moritz: do you have a link to ponie? it seems to be a different project 13:24
moritz fglock: no, it's the same. And it's such an old project that all the websites about it seems to have gone down 13:25
fglock: it was an attempt to bring perl 5 to parrot, though I'm not sure how exactly they tried to do it 13:26
[Coke] most of the people around when that happened aren't with parrot anymore. 13:29
13:30 xinming left
moritz or with Perl 6, for that matter 13:30
GlitchMr Well, you can use "use v5" to run Perl 5 code in Perl 6, but...
perl6: use v5; my @array = 1; print $array[0];
moritz though at GPW I talked to Nicholas++, who seems to have vivid memories :-)

jnthn hi moritz :)
moritz++ # various Rakudo patches :)
moritz thanks :-) 13:52
though fixing URI and LWP::Simple was actually more work :-)
I wonder if should make a star release, or wait til after the April compiler release
13:52 kaleem left
moritz I'm not sold on the idea, but I could imagine doing a star release after the Oslo P6 hackathon 13:53
jnthn A Star release would need a patched NQP release because I failed to get the fix for pre-comp of NativeCall-using modules in. ;S
*:S
moritz ok, then it's probably more economic to wait 13:54
jnthn Yeah.
moritz maybe I'll get around to blogging that tonight 13:55

gfldex are >, >=, < etc pp "derived" from cmp? Or do I have to implement all of those? 14:48
moritz you have to implement them all 14:50
though I imagine that one could create a module that derives them for you 14:51
gfldex sounds like (mostly) macro work to me
moritz aye
for example for strings, eq and ne can easily short-cut when the length is different, but cmp needs to do the full comparison work
so in general, it's not a good idea to always derive all the comparators from the most general ones 14:52

masak my approach to teaching scalar/list context and sigil variance is based on "yes, this is confusing. it's not just you." 18:10
tadzik :P
18:11 s1n left
masak scalar/list context is weird because it flows inwards in expressions. return values flow outwards, and that's the direction we're used to thinking of things flowing in expressions. 18:11
one very bright student asked "how can I create a sub that differentiates context?". I showed them wantarray(). 18:12
(for a brief moment, I seemed to recall it was named "want()". the perils of being a Perl 6 historian.) 18:13
sorear how much flak do you get for being into perl6? 18:14
masak none, so far.
these are people whose relation to Perl is "do you think Python is worth looking into?" or "so, what's Parrot?" 18:15
PerlJam masak: do you get any interest in Perl 6? or confusion about Perl 5/6
?
masak no, no confusion. a mild but distanced interest.
I told them I kept writing 'say' and expected Perl 5 to have it, because I was used to it in Perl 6. 18:16
PerlJam good I guess
masak s/to have it/to have it by default/
gfldex Why would they have interest when they don't know why they would want to have interest? 18:17
moritz that's why I start all my p5 programs with 'use 5.010;'
PerlJam moritz: me too
masak me too, usually.
moritz gfldex: our marketing effort might not have been totally futile :-)
masak gfldex: the name "Perl 6" (when they're still on 5) seems to indicate by default that they should pay a modicum of attention. 18:19
gfldex Until they believe the propaganda on the interweb that Perl 6 is a stillborn.

gfldex they have all stolen from each other :)

Ulti its only recently that I've realised a lot of my perl ends up being functional style, I think Lisp made me hate the concept of functional programming even though its what I have a subconscious preference for 19:21
TimToady yes, Lisp, the most ugly beautiful language :)
jnthn back o/
Ulti and even Lisp I wrote off from using a strange NASA variant called CLIPS
masak Lisp has an obsession with trees :) 19:22
jnthn! \o/
sorear Haskell is a language I know that has a lot of this stuff. 19:23
However, there are no(?) original ideas in Haskell - it's a committee synthesis of the best parts of a baker's dozen similar previous languages, like Miranda and SASL
TimToady perl6: say (((1 => 2) => 3) => 4 => 5 => Nil).perl 19:24

sorear many of those languages owe a lot to ML
Ulti I think I'd rather learn perl6 if I'm to learn yet another language
spider-mario yes, trees might be what repelled me from lisp
writing trees is fun five minutes

p6eval rakudo 68e7f8: OUTPUT«Method 'lol' not found for invocant of class 'Array'␤ in block <anon> at /tmp/4R2gGVazOM:1␤␤»
timotimo supposedly that's the case because that assignment flattens already?
i thought that was kind of "lazily" done?
moritz note that @data.lol would be a noop 19:56
19:57 pernatiy joined
moritz ((1, 2), (3, 4)).lol would return a two-element LoL 19:58
(at least I think so)

jnthn ooh, that was fast :)
moritz :-) 20:07
I could say the same about the fix :-)
tadzik jnthn! \o/
jnthn hi tadzik :) 20:09
moritz: Well, I'm in my hotel hiding from pre-thunderstorm humidity and it was LHF... :) 20:10
masak quick! submit more LHF!
jnthn :P
tadzik precompilation causes segfaults!
:D
jnthn That ain't LHF :P
tadzik dang, thought you may not notice ;)

gfldex not overly DWIM
but it will do :)
21:08 M_o_C left 21:10 zipf left
masak gfldex: fwiw, I don't agree with your intuition that the Day enum type object should listify to all its enums. 21:10
it doesn't feel do-what-I-mean to me.
jnthn Cute today, to magical tomorrow. 21:12
*too 21:13
gfldex my intuition might be fooled by the fact that I give the compiler a list but what the enum gets is a hash
masak no, that in itself is usually fine. 21:14
gfldex if i now go and ask the list back from the enum is is indeed allowed to be confused
masak you can for loop over a hash.
but the enum type object is just that, a type object.
it doesn't expand or explode into its constituent parts. 21:15
PerlJam Is Day.enums guaranteed to give them in a specific order?
masak much like a class type object doesn't exapnd into all its instances :)
PerlJam masak: so ... there's a Class.instances() that'll give me all of them? :)
masak not sure that's such a good idea :) 21:16
r: enum Day <Mon Tue Wed>; say Day.enums.^name
p6eval rakudo 8ead1e: OUTPUT«Hash␤»
masak PerlJam: does that answer your question?
gfldex are enums and their hashes immutable? 21:17
masak yeah. 21:18
they're really a kind of constants.
gfldex can i MONKEY_TYPE them? (that would be crazy :) 21:20
PerlJam masak: Aye. It was curious that no one pointed that out though.
jnthn Well, they're backed by an EnumHOW so you can go monkeying at the meta-level.
But if you do so after CHECK time then on your own head be it :) 21:21
gfldex that could cause some realy cool bug reports :->
masak I'd much rather see switch statements be optimized to jump tables :)
jnthn gfldex: If you submit a bug report saying "I did stupid things in meta-space and X bad thing happened" then it's probably just gonna be rejected. :) 21:22
masak: Yes, optimization happens after CHECK time. Thus my comment on "be careful" :) 21:23
gfldex backs off 21:24
jnthn :)
