raschipi The usual problem with procs is the exact opposite: they do EXACTLY what you told them to do. 04:23
pilne yeah, computers are funny like that 04:24
raschipi Most of the time, it's the wrong thing. We call it a bug.
pilne unless you are treading into "undefined behavior" territory
raschipi There's not 'undefined behavior' for CPU, everything comes down to that at some point. 04:25
geekosaur ob F0 0F C7 C8
(CPUs have bugs too. also ancient CPUs often didn't control what unassigned opcodes did at all...) 04:26
pilne yeup 04:27
ahhhhh the good old days
raschipi Well, those are defined... by the silicon. The docs and specs might not mention it, but the silicon will do something deterministic.
Well, interrupts aren't deterministic. And the interaction in the bus too. 04:28
geekosaur "deterministic" but often based on the exact stepping. and you couldn't even query that (no such thing as CPUID back then)
raschipi "Which core get's to the varible first" isn't deterministic.
BenGoldberg Also, there are such things as hardware random number generators. What numbers such a generator will produce, are generally the opposite of deterministic. 04:29
geekosaur (also at some point this just turne into trolling...) 04:30
*turns
zengargo1le has wondered why hardware RNG aren't common in everything. if a dongle can do it why not have it already built in?
pilne paranoia 04:31
raschipi Well, almost every IO device will act as a RNG. When there's no dedicated RNG, Linux uses almost all IO it can measure to generate entropy, for example.
zengargo1le: Every TPM module comes with one. You can also turn the sound card into one if you have no other use for it.
zengargo1le i'm thinking of those things that catch cosmic particles hitting one side or the other of some sort of detector type of thing. does TPM use that sort of thing? 04:33

raschipi zengargoyle: They use a quantum source of entropy: the noise at the base of a reverse biased transistor. It fluctuates randomly because electrons will tunnel through the gap. 04:38
zengargoyle ah, cool. 04:42
may have to read up on that. guess it's still a slow stream of entropy or we would no longer have PRNG at all? 04:45

raschipi If you need more, just use more transistors. Transistors are what chips have in abundance. 05:01

Hopefully this will help others out, as it is somewhat counterintuitive.		 05:22
samcv ok. i finally got fed up and added this to the docs XD
zengargoyle rand came up a few days ago and my grep led me to believe that it boils down to libtommath (a bunch of math routines for primes and such) which uses arc4something() or rand() depending on availability.
samcv because i always forgot it
05:22 Cabanossi joined, mr-foobar joined
samcv yeah something like that zengargoyle 05:22
zengargoyle it all seems to still be a good entropy seed to some crypto generator (re-seeded at intervals by some logic) vs some actual true endless fast fount of random bits. :) 05:25
samcv so good then? 05:26
05:26 pilne left
zengargoyle good enough for my Lotto number picks. 05:27
samcv you may know more about the intricacies of random number generating than i do
TEttinger man, that's what I've been up to lately 05:28
I have a pretty fast 64-bit one now with what seems to be decent quality but a lousy period for its amount of state (128 bits) 05:29
2 to the 65 period probably, no lower than 2 to the 64
well, pretty fast for software as in "twice as fast as an LCG, at least with the JVM's weird optimization properties" 05:30
zengargoyle TEttinger: you may know more about the intricacies of random number generating than i do :P 05:32
TEttinger this stuff is fun for me. I have a system set up to repeatedly generate random 24-bit numbers and use them as colors, like here i.imgur.com/fpn0Wrq.png 05:36
if there's a flaw, it's pretty easy to pick up, also in black/white i.imgur.com/4biF98x.png
this series tested various intentionally flawed RNGs i.imgur.com/4H5VXcP.jpg 05:38
samcv i still don't know why .grep(:v ) is the same as default
v
Only return the matched elements (same as not specifying any named parameter at all).
where all greps always have grep -v is reversed 05:39
only return non-matching
so i guess you need :!v ?
zengargoyle worst magic-eye ever.
samcv still odd
TEttinger hehe
hobbs :!v is definitely a face 05:41

zengargoyle is there a better list of bots/commands than found on perl6.org/community/irc? 06:14
samcv see all the users that have voice 06:15
those are bots
so i have `my (%hash, @array) = myfunction; sub myfunction { return %hash, @array } 06:16
i get Odd number of elements found where hash initializer expected:
it works fine when i only have it return a hash
so i guess those are somehow coming together.. ack reminds me of perl 5 horrors i've experienced
i think actually it's `return %hash, @array.sort.unique` so it's likely returning a sequence. that could be what's causing this 06:18
though using .list doesn't improve the situation
zengargoyle i'd try .Array but it's just a guess. 06:19
samcv that's not a method :P
err. wait it is
heh. let me try it
zengargoyle m: (1,2,3).Array
camelia ( no output )
zengargoyle m: (1,2,3).Array.say 06:20
camelia [1 2 3]
samcv ok now something really weird happened
eek. well i'll be back in like 20 mins or so
06:20 nadim joined
zengargoyle tends to slap on a .Array whenever some error pops up (esp. Seq errors). gah, i think i haven't wrapped my head around Seq yet. 06:22
raschipi zengargoyle: That's almost the appropriate way of doing it, but there's an specific method to do it: .cache (docs.perl6.org/routine/cache) 06:28
zengargoyle heh 06:30
method cache(--> TODO)
06:32 webart joined
zengargoyle guess this is more relevant: method cache(PositionalBindFailover:D: --> List:D) 06:32
raschipi The lower section explains what it does: turns an iterator into a list. Just don't call it on infinite or ver long lazy lists. It will eat all of your memory. P6 doesn't do it automatically because it can't know which lists will grow to much and turn out impossible to fit into memory. 06:33
Even if you got infinite memory, it will take infinite time to fill it up.
zengargoyle yeah, favorite recent bug-fix was along the lines of "no longer segfaults, will consume all available memory instead" :) 06:34
just like you told it to. 06:35
06:36 Cabanossi left 06:37 Cabanossi joined
raschipi Seqs are annoying sometimes, but they are very useful. The GC can reap the part that was already dealt with and allow much bigger problems to fit into memory. 06:39
Easier than having to do it by hand.

raschipi This last one is a type check failure, which means we're violating a promise we made to the compiler. 06:59
zengargoyle why is the hash not also itemized?
07:00 darutoko- joined
zengargoyle why is %h not { a => 1, b => 2 } => [ 1, 2, 3 ] 07:01
raschipi P6 doesn't mangle structures like that, it keeps everything tidy. 07:05
Lists don't end um mixed or flatened. 07:06
zengargoyle then it seems (%h,@a) = (%x,@y) should work. 07:07
raschipi Asignement calls a method on the object in the righ hand side, and hash doesn't know what to do with a odd-numbered list. 07:08
On the left hand, even.
zengargoyle m: my ($h, @a) = ( { a => 'b' }, 1 ); say $h; say @a; 07:10
camelia {a => b}
[1]
nine zengargoyle: the sad truth is that hashes are flattened more easily than lists. Feels like a bit of an oversight during the GLR.
zengargoyle m: my ($h, @a) = ( { a => 'b' }, [1,2,3] ); say $h; say @a; 07:11
camelia {a => b}
[[1 2 3]]
zengargoyle nine: gotcha
raschipi Is 6.d the opportunity to fix that? 07:14
zengargoyle hopefully only if they can keep 6.c vs 6.d semantics about the same way p5 only changes if asking for the new stuff. 07:16
zengargoyle still miffed that { use 6.c; ...old-code...} didn't fix my IO breakage.
raschipi I think the idea is to keep everything that asks for 6.c at the top working. 07:17
zengargoyle but not that miffed.
nine The idea is good but object orientation puts a severe limit on that
zengargoyle yeah, best effort is fine by me no matter my complaining. :) 07:18
raschipi Use 6.c inside a block could help with syntax changes, but the objects have global state.
nine It's downright trivial to have the compiler bind to the right await sub depending on the language version. But methods are late bound. It doesn't at all depend on the caller of which method is found but on the object the method is called on. 07:19
raschipi Their dispatch tables are global.
07:19 lizmat joined
zengargoyle yeah,IO is a thing unto itself. 07:20
raschipi zengargoyle: Doesn't have anything to do with IO, :) . It would be the same for any object. 07:21
zengargoyle just breaks my ask for 6.c get 6.c expectations and maybe future compatibility. p5 did the same thing around 5.10 or so bringing about all of the 'experimental' and 'feature' stuff. 07:23
how much legacy do you want to support with minimal tweak of asking for the old behavior? 07:24
raschipi You have to keep in mind that these versions are for the language, for the syntax, but that the breaking changes were made in a library.
The way to fix that would be to create objects with multiple interfaces. 07:25
Adding a :old-model adverb to IO or something. But then, standard handles already start instantiated. 07:26
zengargoyle eh, my breakage was simple IO. but point taken, the boundry is fuzzy.
raschipi It's like the difference between GCC and LibC. 07:28
nine Would be all doable. But what the heck should happen if 6.d code passes an IO::Path object to 6.c code?
zengargoyle and it was really just like one line of testing code.
raschipi nine: croak 07:29
zengargoyle hehe, you can wrap a Python interpreter's object in a p6 object. nothing is impossible! (just not worth it) 07:30
and i'd rather the effort be spent elsewhere ATM anyway.
zengargoyle just musing on how awesome it would be if it actually did do that thing. 07:31
nine Actually it should even be possible for a method to ask for its caller's language version. This is Perl 6 after all ;) It just would be quite bad for performance and for maintainability of the code... 07:34
raschipi nine: I see where the problem is now, the 6.c and 6.d code are from different authors. 07:35
And these methods are intermingled in with the operating system and represent things people just expect to be there. It wouldn't be so hard if people had to set up their IO instead of just using it. 07:36
zengargoyle yeah, i give wide berth when you hit IO or some other systemy thing vs just high-level syntax. 07:37
i hope things settle down by 6.e or 6.f where it becomes "if it worked it still does" (most likely). 07:42
raschipi The good news is that the same companies that are paying for P6 development are the ones paying for P5 development, so they will want the same guarantees eventually. 07:44
nine Well IO was an area that lagged behind the rest of the setting when we released 6.c. There was bound to be some changes. 07:45

hobbs it's unnecessary (either the function should have its own lexical, or if it's going to assign to an outer one, it doesn't have to also return it) 09:54
but it's the same effect as my %pnamecode; make-name-alias-hash(...); %pnamecode = %pnamecode;
samcv i never declare it inside the sub though
so it must use the outer one 09:55
hobbs yes
samcv m: my $a = foo; sub foo { $a = 100; return 10 }; say $a 09:57
camelia 10
samcv though this also works too
hobbs which is in-scope, it hasn't been assigned to yet (because make-name-alias-hash hasn't returned yet ;) but it's still usable as a container, same as if it didn't have an initialization at all.
I don't know if it's guaranteed, but it's the behavior I'd expect 09:58
samcv anyway thanks for helping me underertasd it
hobbs then when the assignment part of the initialization does complete, it effectively does nothing
10:04 avalenn_ left
hobbs the equivalent code in perl 5 would behave the same, FWIW, so my expectations are already set ;) 10:06

nine The declaration of $a happens at compile time, so during compilation of sub foo, it's already known. So indeed foo refers to the container named '$a'. When _running_ the assignment, first sub foo is called, which already assigns to $a and then returns a value which again gets assigned to $a 10:28

vimal2012 What is the practical use of sigilless variable? Why would one want to use sigilless variable over sigilled one? 10:59
llfourn vimal2012: I think sometimes it's a decent way to indicate that you don't want to have a variable with a container 11:06
or more simply is read only
m: my \foo = "foo"; foo = "bar";
camelia Cannot modify an immutable Str (foo)
in block <unit> at <tmp> line 1
llfourn so it tells the reader that you aren't going to modify the variable after declaration 11:07
unless there's a particular reason you want to point that I wouldn't use them 11:08
jnthn They're also useful in the cases where you don't want to enforce any kind of context 11:13
my \matching = $fh.lines.grep(&condition).map(&operation); for matching { } # Will iterate the lazy pipeline, discarding values, so using little memory on a large file 11:15
my $matching = $fh.lines.grep(&condition).map(&operation); for $matching { } # Only does one iteration, because $ means item
my @matching = $fh.lines.grep(&condition).map(&operation); for @matching { } # assignment is mostly eager, so will store all the matching lines in @matching before doing the iteration 11:16
This means if you're constructing lazy processing pipelines they are also a pretty good choice.

rightfold The syntax highlighting for Perl 6 makes Vim extremely slow. 12:09
Am I using an old version? I am using the version that ships with Vim. 12:10
What should I upgrade to?
El_Che github.com/vim-perl/vim-perl 12:13
rightfold Should I install github.com/vim-perl/vim-perl6?
El_Che that the latest version
not slow at all on Ubuntu 16.04 and 17.04 12:14
rightfold I find this repository confusing.
"Support for Perl 5 and Perl 6 in Vim"
"This is the aggregation of all the various Perl-related syntax and helper files for Perl 5. For Perl 6 files, please see vim-perl6."
El_Che rightfold: this are the notes of my vim setup: nxadm.wordpress.com/2016/08/21/vim...-6-editor/ 12:15
rightfold So I do not have to "see vim-perl6"? 12:16
El_Che I haven't had time to work on synastic-perl6, but it works as is
rightfold: no
rightfold OK
Thanks
El_Che just clone it and you're good to go

zengargoyle_ rightfold: have you ever checked out nvim? i switched way back when because it was faster at syntax highlighting and checking than vim (around the 7.0 era). 12:42
rightfold oh '-'.IO.lines works, but '-'.IO.slurp doesn't 12:44
zengargoyle_ it was the whole async thing that i think maybe vim 8 does now, highlighting, make/perltidy/perlcritic on write, etc. are threads so no delays.
rightfold I don't use any code analysis or building features in Vim 12:45
My setup is a tiling window manager where one of the terminals houses a file watcher that does the analysis and building
It is less distracting than constantly moving frames and squiggly lines and popups
zengargoyle_ gotcha, nvim still seemed to do highlighting faster or at least in a way that didn't interfere with typing. depends on whether your issue is with slowness or with flakey highlighting as a whole. 12:49
