colomon sorear: in retrospect, I feel very stupid for not handling Rats and FatRats when I did Ints the other day. Wasn't thinking about what it would take to do it.... 01:08
01:14 Tanktalus joined
colomon sorear: why do you need Func<Constants,Variable,Variable,Variable,Variable> for a function which takes three variables 01:19
?
sorear takes three variables, returns one variable, and also needs a reference to something that can be used to fetch JunctionMO 01:21
colomon ah, I see. makes sense, somehow I missed adding the Variable when I added the Variable, if you know what I mean. :) 01:23

sorear colomon: if you don't, I will 01:49
colomon sorear: I understand your basic suggested algorithm, I'm just trying to figure out a graceful way to get the random bits
I see a BigInteger.genRandomBits online, but apparently it's not in "our" BigInteger? 01:50
Random.NextBytes? 01:52
is RNGCryptoServiceProvider.GetBytes available to us?
sorear colomon: anything which is listed as being part of the .NET framework version 2.0 is available 01:55
colomon ooo, so RNGCryptoServiceProvider.GetBytes is! 01:56
sorear "our" BigInteger is a copy of the BSD-licensed System.Numerics.BigInteger from Mono 2.8.x, backported to Mono 2.6 and patched to add bounded serialization
colomon ah 01:57
sorear I'm a little bit ambivalent about using RNGCryptoServiceProvider for this because our existing randomization primitives use the non-crypto System.Random 01:58
colomon it's an easy change either way, right?
sorear right 01:59
msdn.microsoft.com/en-us/library/sy...bytes.aspx fwiw
colomon yep
sorear methinks perl 6 should offer crypto randomness somehow 02:00
and modern crypto RNGs are fast enough that it might not kill us to us them everywhere 02:01
one of my previous projects was an online game
open-source
one of the users cheated by using leaked information to solve for the RNG seed and then predict all game events 02:02
colomon hardcore
sorear the response was to switch all game logic to use a crypto RNG, it... worked suprisingly well
but we weren't using a system-provided RNG anyway, so I have no idea how fast the standard RNGCryptoServiceProvider impl is 02:04

sorear colomon: Buildins.rng I think? there's also a locking protocol in use 02:18
colomon okay, will test it with regular random and then look at switching. 02:21
sorear: gist.github.com/3773886 is what I've got so far. It's got at least three issues, I think, but I need to get to bed. Please feel free to hack on it or completely replace it as needed. Or I'll take a look at it again in the morning. 02:33
jferrero /leave 02:36
02:36 jferrero left 02:39 cibs left
sorear colomon: the issues I see are 1. needless switch 2. use of the capitalized name Byte is stylistically inconsistent with other parts of niecza 3. might misbehave with negative numbers 02:39
colomon oh, switch is just 2 ** (bits % 8) - 1, isn't it? 02:40
02:41 cognominal joined
sorear also 02:41
I mean yes
although I'd be more likely to write that 1 << ... 02:42
colomon I'm assuming positive numbers for the input, and added an extra 0 byte to avoid negative numbers
sigh, of course. I'm slow on the uptake tonight.
sorear mostly I'm just interested in avoiding division
colomon actually, the number one problem is that it doesn't work -- there's a weird array bounds error in the BigNumber constructor sometimes.
sorear since that's a slow operation with our bigint library (and in general, but especially so for us) 02:43
colomon division?
sorear as in /
colomon that's on an int
though I guess it could just be bits >> 4
C# int, I mean 02:44
sorear moritz' original algorithm used bigint division
yours doesn't
colomon ah
sorear thinks it's hilarious that GMP uses Newton's method for division in certain cases 02:45
colomon anyway, I should definitely be getting to bed now. apologies for leaving the job unfinished.

tadzik Ulti: you can do =begin code\nblablabla\n=end code, and then $=pod[$n] will give you a Pod::Code block 11:18
which is a raw, non-processed data
Ulti awesome
thanks tadzik
tadzik do you know how those $=pod array works? 11:19
Ulti nope?
tadzik well, it's just an array of pod blocks :)
but you have to be aware that indexes will change if you move stuff around
Ulti that's ok
tadzik so if you put two blocks like this, you'll have them as $=pow[0] and $=pod[1], depending on the ordering
Ulti easier than if I had external files and moved them around 11:20
tadzik sure :)
11:20 ServerSage joined
Ulti tadzik: is it part of the spec to preserve the indexes based on the ordering in the file? 11:20
tadzik Ulti: I think so
Ulti so I can rely on it?
ok
tadzik well
spectests rely on it
Ulti "rely"
I can just add a string to the top so I know which is which
11:20 mucker joined
tadzik see github.com/perl6/roast/blob/master...elimited.t for example 11:21
Ulti perfect thank you
tadzik you're welcome
11:22 kenjiskywalker left, kurahaupo joined
Ulti oh you can just use .name to find the right section 11:24
tadzik ...the spec says so, yes... 11:25
I work on Pod far less than I should these days
11:26 kenjiskywalker joined
Ulti tadzik: looks quite functional to me! 11:29
tadzik huh, it works? :P
I mean, .name?
Ulti yeah
11:29 mtk joined
moritz thought .name just reported the name 11:29
tadzik O_o I don't remember implementing that...
the name from :name<foo>? 11:30
Ulti yeah it reports just the name, so finding the right section by name is quite easy
tadzik ok, cool
moritz tadzik: I think that =begin code ... =end code makes .name eq 'code'
tadzik shouldn't be too hard to make $=pod associative too then
ah, that's right
so it comes from Pod::Block::Named
or so 11:31
Ulti yeah thats what I see
now thats done, LUNCH!
:) thanks

spacebat_ is there much in the way of introspection in rakudo - such as in python there help(dict) might tell you more than you wanted to know about dictionary types 14:27
colomon spacebat_: I believe rakudo has that, but I don't recall the way to trigger it off the top of my head. 14:28
spacebat_ so, not introspection per se, but inspectable docstrings
colomon right
arnsholt Documentation is a bit of a sore point, IIRC, but introspection via the MOP we have in spades 14:29
colomon (there is real introspection as well)
14:29 sirrobert joined
arnsholt Although the p6doc project is helping on the docs front 14:29
colomon spacebat_: tadzik++ did the work to implement it, I just wasn't paying close enough attention to remember how to do it.
Su-Shee is help() in python a mix of pydoc foo and foo.WHAT so to speak? 14:30
tadzik I dunno what's help() in python
spacebat_ it pulls the docstring of the object (which may be a module) and formats it nicely
tadzik we could write that 14:31
Su-Shee spacebat_: what's the difference to pydoc if I may ask stupidly?
spacebat_ help is available at the python repl
I'm no python expert - haven't used it a long time - perl5 is my dayjob
moritz well, the idea is that you can &foo.WHY and get the Pod back 14:32
Su-Shee spacebat_: oehm then I have no clue :)

spacebat_ I'm just playing around, got an IO::Path object, wondered what I can do with it
moritz in particular the link between the perl6/doc repo and $obj.WHY is still missing
spacebat_: I think that's described in S32::IO
spacebat_ yup, I just wondered if I was missing out on some self documentation features 14:34
colomon phenny: tell sorear it turns out my array index bound error was a BigInteger bug: sending the constructor the number 0 stored as two or more bytes fails.
phenny colomon: I'll pass that on when sorear is around.
pmurias #= for inline POD is implemented? 14:41
14:41 sisar joined
moritz yes, I think so 14:41
not for every object type though
but it should work for subs
tadzik subs, classes, methods 14:43
not for variables though
last time I tried it was segfaulting :)
but that was long ago, could be differentnow
also module, package etc
spacebat_ so for introspection, say I have an object, what's the best way to list the methods and attributes of the object or its class? 14:45
hoelzro $obj.^attributes
$obj.^methods
(iirc)
spacebat_ thanks :)

[Coke] if I squint, that looks like perl. ;)
GlitchMr I've made a completely pointless task at Rosetta Code
rosettacode.org/wiki/Detect_input_c...g_from_tty
Also, shouldn't the primarity be memoized? 18:19
colomon GlitchMr: I was thinking about that, but I'm not sure it's a good idea
there are a LOT of prime numbers.
GlitchMr Why not?
oh, ok
TimToady colomon: no, there are more than that, I suspect 18:20
colomon I guess if the cache was smart enough to drop off older / larger entries...
TimToady: more than a LOT? prove it!
;)
TimToady I don't want to prove it, which is why I said "I suspect"
colomon is eager to hear if the latest niecza helps on the rc prime chain problem.... 18:21
though I guess we wouldn't know the answer for hours even if you started now, right? 18:22
[Coke] finds the original twin primes paper he was referring to, where they say "A client takes an average of 60 minutes to process a 18:24
range of 10 billion numbers"

[Coke] I am tempted to kick off that line to see how long it takes rakudo on feather. 18:24
(cgi2.cs.rpi.edu/~szymansk/papers/hpdc.98.pdf in case anyone wants to read it. ... huh. I'm in the Acks at the end. nifty.) 18:27
colomon just started attempting to find all the primes to 10000000000 under niecza. 18:28
colomon suspects it will take a while

tadzik I'm not sure I understand why is-prime is core 18:30
I find it hard to imagine a program, whose the purpose is something else than calculating primes, to make use of it
flussence +1 18:31
colomon tadzik: crypto
tadzik well, ok. Are gonna push RSA into core as well?
s/Are/Are we/
I think it's just too niche of a usecase to be in core. A module, of course! But core? 18:32
[Coke] "and those shoes!"
18:32 daxim left
tadzik yes, one day we'll be loading all these ondemand. But until this day we'll whimper at how heavy we got from all those features we (almost) never use 18:33
ok, I'm shutting up again
colomon tadzik: the thing is, it's hard for a module to do well
that is, rakudo is calling straight into its underlying bignum library, and niecza is doing the same for the expmod portion. 18:34
maybe when the module ecosystem is more developed, it will be easier to move them out to a module...
FROGGS there should be a way to do that in a module though
PerlJam FROGGS++ (assuming that really was meant as humor :) 18:35
FROGGS no, I know that there are (or better will be) modules that need a bit more hardcore stuff and these modules will need to talk to nqp or mono or whatever 18:36
for performance reasons for example
18:37 imarcusthis- joined
colomon FROGGS: right, but to do it smoothly, we need to be able to create a module which 1) can talk directly to nqp or mono or whatever and 2) do the right thing no matter what system it is using. The ecosystem isn't nearly that well developed yet. 18:37
18:37 GlitchMr42 joined, daniel-s_ joined
FROGGS basically you just can have submodules you load when detecting the right system 18:38
like File::Spec doesnt load ::Win32 stuff on linux (because Win32 might include Win32 modules that cant be installed on other systems)
I dont think there will be some magic that picks the right system specific code for you out of a bag 18:39
18:39 GlitchMr left, GlitchMr42 is now known as GlitchMr
PerlJam FROGGS: as long as we have the same interface no matter the underlying implementations. That's where the "magic" is 18:40
FROGGS I am talking about not using some sort of interface/layer in between 18:41
I know from the work on the SDL module that this won't be enough in every case
PerlJam FROGGS: not for the every-day programmers, but it'll have to be *somewhere* 18:42

masak it's like, in the space between arrays and hashes, things are just elements of lists, floating around in the ether. 19:56

sorear spectest run finished 22:44
colomon: ping
colomon: deping, my fault 22:49
22:50 doy_ joined
sorear looks like no real failures 22:50
22:50 ranguard_ left, ranguard joined, doy left 22:51 doy_ is now known as doy
colomon sorear: yeah, I don't know what's up with the transient failures 22:56
sorear colomon: one set of failures was version skew, I was trying to test your new pick.t without your pick patches 22:58
(apparently this causes the test to go into an infinite loop which I killed after 90m)
the chdir.t tests, I blame the fact that I was doing funny things with the t/ dir and symlinks 22:59
some other failures were caused by TEST_JOBS=3 and niecza's dislike of concurrent access to the module cache
the quoting.t stuff is a mono bug which I reported a few weeks ago but nothing has been done with 23:00
(OSX-specific)
which just leaves a TODO pass in eqv.t :D
23:01 benabik joined

colomon +1 on the announcement 23:33
sorear: ^^
I'm getting failures in t/spec/integration/lazy-bentley-generator.t and t/spec/integration/lexical-array-in-inner-block.t fairly frequently during the spectest.
but they always are fine when I test them by themselves. 23:34
that's on both OS X and Linux.
23:34 bruges_ joined 23:35 daniel-s__ joined
sorear colomon: do you run the spectest with TEST_JOBS? 23:35
I think it's relevant that those are two very early tests
I think they're failing because of contention on the module cache 23:36
23:36 bruges left, daniel-s_ left 23:37 benabik left, daniel-s__ is now known as daniel-s 23:45 benabik joined
colomon yes, that's runs with TEST_JOBS=4 23:46
