00:00 * dukeleto *really* feels like his old phd advisor now
00:00 Yuki`N I'm not entirely sure that paper even has sentences.
00:00 dukeleto Yuki`N: mathematicians have their own language :)
00:00 Yuki`N Starting from their definition of y and a around eq 4.
00:00 Yuki`N lol
00:01 dukeleto Yuki`N: here is the deal
00:01 dukeleto Yuki`N: we break up the computation of pi(x) into parts
00:01 dukeleto Yuki`N: some parts are easy, some are hard
00:01 dukeleto Yuki`N: the hard part is an infinite sum
00:02 dukeleto Yuki`N: but then they have a trick for only needing to add up a finite number of terms
00:02 Yuki`N the easy part it seems is that function P(x, a)
00:02 dukeleto Yuki`N: π(x) = φ(x, a) + a − 1 − P2 (x, a)
00:03 dukeleto Yuki`N: that is important, write that down
00:03 Yuki`N I already put that down.
00:03 dukeleto Yuki`N: the hard part is figuring out P2(x,a)
00:03 Yuki`N But that section is only half a page long
00:03 Yuki`N and the part of phi(x, a) is like 4 sections.
00:03 dukeleto Yuki`N: hmm. you are right. The hard part is  φ(x, a) :)
00:04 Yuki`N And I still can't figure out how to compute P_2(x, a) because I'm not sure how I'm determining y and a.
00:04 Yuki`N Would I just recurse until a is some small prime?
00:05 dukeleto Yuki`N: there is a recurrence relation to compute φ(x, a) : φ(x, b) = φ(x, b − 1) − φ
00:05 dukeleto x
00:05 dukeleto ,b − 1
00:05 dukeleto oops
00:06 dukeleto sorry, copy+pasting from PDFs dangerous, evidently
00:06 Yuki`N They split phi(x, a) into a binary tree type thing, so that the root is equal to the sum of the leaves at the bottom
00:07 Yuki`N but then they go a step further and...
00:07 Yuki`N start breaking sub-sums into more sub-sums
00:07 Yuki`N and I just.
00:07 Yuki`N don't understand.
00:07 dukeleto Yuki`N: are you still working on the is_strong_lucas function?
00:08 Yuki`N I finished that.
00:08 dukeleto Yuki`N: a = π(y)
00:08 dukeleto Yuki`N: and you get to choose y, methinks
00:09 dukeleto Yuki`N: this is hard. No doubt about it.
00:09 dalek Rosella: f84af18 | Whiteknight++ | / (19 files):
00:09 dalek Rosella: Dumper is version 1.
00:09 dalek Rosella: review: https://github.com/Whiteknig​ht/Rosella/commit/f84af18a29
00:09 Yuki`N I think then we have to recurse until pi(y) gets small enough.
00:09 dukeleto Yuki`N: what about implementing π(x) the easy first, in Winxed. Does that sound more reasonable?
00:09 dukeleto s/easy/easy way/
00:10 dukeleto Yuki`N: you can just port the code from the Math::Primality perl 5 module straight up.
00:10 dukeleto Yuki`N: i think i made this task too hard :)
00:10 Yuki`N lol
00:10 whiteknight called it!
00:10 Yuki`N the for-loop way?
00:10 dukeleto Yuki`N: yeha
00:10 dukeleto Yuki`N: the dead simple way :)
00:10 Yuki`N haha, alright.
00:11 dukeleto Yuki`N: i would love to help you implement the optimized version, but I also don't want to bog you down when you could be doing other tasks
00:11 dukeleto Yuki`N: ok, just marked the task complete, will do a full review a bit later
00:12 dukeleto Yuki`N: nice work!
00:12 Yuki`N alright.
00:12 dukeleto whiteknight: there is still another date where the last set of tasks gets released, right?
00:12 whiteknight Dec 16th, methnks
00:13 dukeleto Yuki`N: because you are going to do the *way* easy version of prime_count(), can you implement next_prime() and previous_prime() too? They are about 4 lines each, dead simple.
00:14 Yuki`N alright.

02:20 whiteknight done
02:20 whiteknight I would wish you good luck, but I suspect that's not necessary
02:21 Yuki`N I've already finished, actually.
02:21 Yuki`N To avoid suspicion I'll wait until a bit later to submit, though./
02:27 whiteknight cotto: if packfiles are associated with file names, and we have ready access to version numbers and UUID strings, we can create strong names for each library, which is a security essential
02:27 whiteknight for instance, we can do a packfile load with file name, specific version, and even specified UUID, and fail if any of those things don't match

02:34 cotto whiteknight, istr that the uuid strings (and related code) were pretty stubby.
02:35 whiteknight it's all pretty stubby, but I'm getting through it all slowly

02:39 dalek parrot: review: https://github.com/parrot/parrot/commit/f4defab0d7
02:39 whiteknight git now it appears generated packfiles get the version number of the Parrot that generated them
02:39 whiteknight and that's suboptimial
02:40 whiteknight When we have PACT, we're going to need a method to set the version number on the generated bytecode
02:40 cotto It doesn't reflect actualy compatibility very well.
02:41 whiteknight no
02:41 whiteknight eitherway, I have what I need for Rosella now
02:42 cotto is there a strong reason to keep it when we have explicit bytecode versions?

04:12 benabik Version number of the generated bytecode?  I thought the version number was for the packfile format, not the packfile.
04:14 benabik 0x13155a1 ? Is that supposed to be something?
04:16 benabik (Magic number for PBC)
05:18 cotto benabik, there's some small basis for it, but it's mostly important that it be unique.
05:37 dukeleto msg alvis i like the idea of a parrot vm spec. Our docs/pdds are supposed to be that, but many are wrong/old/bitrotten

13:36 benabik o/ #parrot
13:37 whiteknight hello benabik
13:46 whiteknight let me tell you what: Writing new ops for Parrot is infuriating
13:46 benabik How's that?
13:47 whiteknight if you have a C syntax error in the op you write and try to make bootstrap-ops, it takes forever to find it and then it's overwritten a bunch of files so you can't build parrot and try again
13:47 benabik Ah.
13:47 whiteknight yeah, it sucks
13:47 moritz can't you just type 'make'?
13:48 whiteknight moritz: no, because opsc overwrites several source files with the invalid code
13:48 whiteknight so you need to revert about 4 files before you can make
13:49 moritz :(
13:49 moritz whiteknight: that's terrible design of the build system
13:50 moritz nqp uses separate steps for building and for bootstrapping
13:50 moritz and building doesn't overwrite anything (except old builds)
13:53 whiteknight yes it is a terrible design, hence my complaining
14:00 whiteknight blah, and then we have tests in the suite testing to make sure we have an exact number of ops
14:00 whiteknight and the test fails any time you add or remove an op
14:00 moritz just remove that test.

14:03 whiteknight already did :)
14:03 whiteknight msg cotto can you take a look at some of the new ops I added in the pcc_ops branch? They're pretty important for some upcoming PCC refactors I'm planning.
14:03 aloha OK. I'll deliver the message.
14:04 benabik flatten_*_arg?
14:06 moritz whiteknight: the socket PMC has a readline method, but rakudo needs a more general method which allows a custom delimiter besides \n
14:06 benabik whiteknight: Docs on the new invoke/invokecc variants would be nice. ;-)
14:06 whiteknight moritz: okay, so what if we pass in an :optional delimiter argument to Socket.readline?
14:06 moritz whiteknight: either that, or a separate method
14:06 whiteknight moritz: which would Rakudo prefer?
14:07 moritz whiteknight: both are fine. We need to wrap it anyway for type marshalling, so it's all the same to me
14:07 whiteknight moritz: okay. I don't know if I will have a lot of time to do it myself this week. When is it needed?
14:08 moritz whiteknight: I can even try it myself, just wanted some feedback first
14:08 moritz any example of a method in a PMC that takes an optional argument?
14:08 whiteknight oh, okay. Yes it sounds very sane to me. Whichever variant you prefer should be fine
14:08 whiteknight moritz: src/pmc/imccompiler.pmc .compile() and .compile_file() methods take optional parameters
14:09 whiteknight I don't think :optional works with :named. There are some examples of that combination in that file which aren't used, but didn't appear to work when I tested briefly
14:09 whiteknight so, just stick with :optional
14:09 moritz ok
14:09 moritz so, pretty much like in PIR :-)
14:21 benabik whiteknight: Looks like you're breaking up set_args into pieces?
14:39 whiteknight benabik: yes
14:39 whiteknight benabik: http://whiteknight.github.com/201​1/05/12/pcc_refactor_timings.html
14:44 benabik whiteknight: I notice that the block labeled PASM for optional/positional stuff is actually PIR.
14:44 benabik (about 2/3s of the way down)
14:45 whiteknight ah, looks like a copy+paste error
14:45 whiteknight that post is several months old and nobody has mentioned that yet
14:45 benabik And the fast way of doing optional positional is probably checking a length argument.
14:45 benabik It's easy to gloss over the code.

22:02 aloha OK. I'll deliver the message.
22:02 alvis seen NotFound
22:02 aloha NotFound was last seen in #parrot 1 days 19 hours ago saying "cotto: doesn't matter, just let people send money and we'll manage to find something to do with it ;)".
22:04 NotFound ~~
22:04 alvis NotFound: Hello.  Got a coupl'a questions: Are you familiar with the JVM Specification?
22:05 NotFound I know it exists ;)
22:05 alvis NotFound: Ok, well, I'm thinking about doing something similar for Parrot and in it, it features Java ...
22:06 alvis NotFound: so, I was wondering if you'd be opposed to me featuring Winxed?
22:06 cotto unsurprisingly
22:06 alvis cotto: :)
22:06 cotto +1 (or more)
22:06 benabik JVM spec was amazingly clear when I had to work with it.
22:06 cotto We should encourage things that aren't PIR.
22:07 NotFound alvis: featuring in what sense? Providind example or test code in it?
22:07 alvis cotto: right, i'd also like to do nqp-rx, at least.
22:07 benabik I like the Anything but PIR ticket for 2012.  :-D
22:07 alvis benabik: Yeah, that's one of the virtues of the spec or any spec: clarity.
22:08 NotFound Anyway, I don't oppose the use of winxed for anything. On the contrary, I encourage world domination.
22:08 alvis NotFound: Basically, a syntactic and semantic description of the language, along with example code (like your examples)
22:09 alvis NotFound: Ok, thanks.  I wanted to ask you _before_ I included it in my proposal for a Parrot VM Specification document.
22:10 NotFound alvis: if you want clarity, I proclaim here, in front of the parrot community, that I authorize and encourage you.
22:11 alvis NotFound: Ha! :) Good 'nough!
22:12 PerlJam NotFound: does that mean that you want alvis to re-write most of the parrot core in winxed?  ;)
22:12 alvis cotto: Do you have any other language(s) you think I should look at for consideration or inclusion?
22:12 Yuki`N I for one encourage things not in PIR.
22:12 NotFound (maybe I've should be used majestic plural?)
22:12 PerlJam NotFound: you should have said "Hear ye! Hear ye!" too
22:13 benabik For a VM spec, PIR is actually one of the better things to use at the moment.  PASM might be better if it's actually functional (which I have little proof of at the moment).
22:13 NotFound I have enough problems with present days english, won't try medieval.
22:14 benabik I'd discourage nqp-rx for the purpose as what it generates isn't really clear.
22:14 alvis benabik: Well ..., there will have to be some (don't know how much, at this point) recourse to PIR.
22:14 benabik (Not that I was asked.  >.>  <.< )
22:15 alvis benabik: ... and it's sooo slow.  haven't had the chance to figure out why. <shrugs>
22:15 PerlJam alvis: could you comparatively quantify the slowness?
22:16 benabik My guess on nqp-rx speed is find/store_lex being slow and it using Integer and Float PMCs instead of I and N registers.
22:16 benabik PerlJam: My nqp-rx PCT port took about 2x the time to compile Rakudo.
22:16 cotto NotFound: I feel the same way about nqp-rx.  Also, it's designed for people interested in Rakudo more than as a general-purpose language.
22:16 nbrown joined #parrot
22:17 benabik And nqp-rx generating way too many find/store_lex ops…  I wonder if we could use mls++'s directaccess additions to improve that.
22:17 cotto alvis: only winxed comes to mind atm.
22:18 alvis PerlJam: Not at the moment, but on the tests I've ran, it really lags.
22:18 NotFound Guys, be nice. Don't say that nqp is slow, just say that winxed is fast ;)
22:18 benabik nqp is reasonable, AFAICT.  nqp-rx is slow.  ;-)
22:18 Yuki`N msg dukeleto i've got some code for you to review: http://www.google-melange.com/gci​/task/view/google/gci2011/7197337
22:18 aloha OK. I'll deliver the message.
22:19 Yuki`N I'm suprised by the relative speed of winxed.
22:19 Yuki`N Given that it's running on an interpretive VM, it's not that bad.
22:20 benabik For sheer numerical work, Parrot should be pretty good.  :-D  There are some pain points in our object system, though.  :-/
22:21 Yuki`N I propose JIT should be a GSoC project.
22:22 NotFound The drawing of R->R functions in the graph example of Guitor looks reasonably fast. Have somenone looked at it?
22:26 alvis Ok, just to be clear, the general consensus for inclusion in a PVM Spec is winxed (and some) PIR?
22:26 NotFound +1
22:27 alvis and I will submit a well-formulated question about the same to parrot-dev/parrot-users.

22:47 whiteknight hello cotto
22:54 NotFound whiteknight: the change you propose for winxed will work with the current release, or depends on master?
23:19 whiteknight NotFound: depends on master
23:19 whiteknight I added that second parameter to master yesterday
23:21 NotFound whiteknight: I'm going to wait a few days, then.
23:21 whiteknight okay, no rush
