hm n/m i found good info 04:00pm hm thanks to petri nets i now see why people assume a lot of crap about arrow is anyone here a petri nets fan? 04:10pm I'm not a fan.. but have used it what do petri nets offer that state-diagrams or data-flow don't? it's mostly a generalisation of those state-machines.. not disjunct from it s/those/ it is also formalised and there is good documentation and examples where is a white paper? old petri's phd? ;) yeah which isn't online http://www.daimi.aau.dk/PetriNets/ i think odp has a section for 'em yeah that's where i've been searching from (the petri nets site, not odp) you might want to pay the local library a visit no, odp doesn't have it I am sure they have books about the topic that's great but my budget is already taxed by books you pay at libraries? heh no, i don't live close enough to a university americans are a funny people ;) which reminds me to pay the local library a visit and renew some odd 20 books i guess i was thinking of yahoo ( http://dir.yahoo.com/Computers_and_Internet/Programming_Languages/Colored_Petri_Nets/ ), links of which u'v probly seen already 04:20pm but borrowing books from a library is free, no? libraries haven't been commercialised I hope water: in irc/1999.0816 i seemingly gave u some petri related links yes, but taking the time to visit the library and request a book takes valuable time fair enough.. my local library is only a five minute walk from my office yeah, and you live nearby a major cs institution, iirc yup I might of course drop by my advisor's office and borrow books there as well wow. i can hardly imagine having an "advisor" it's more like "misleader" :) he is at cornell this semester anyway and I have a key to his office though s/and/but/ 04:30pm -:- SignOff hcf: #TUNES (Ping timeout for hcf[me-portland-us734.javanet.com]) -:- SignOff n8j: #TUNES (Ping timeout for n8j[63.20.101.208]) -:- hcf [nef@me-portland-us734.javanet.com] has joined #tunes -:- SignOff smoke: #TUNES (z!) foo quux something to be discussed, i take it? of course on rewriting? among other things, yes unfortunately i don't know where to begin got questions? 05:10pm well, not sure enough what you're doing with rewriting yet to ask questions nothing major, just trying to find it's limits i mentioned recursive message-code earlier that would certainly invoke rewrite, but we'd need a primitive for concurrency (fork? or union?) to have it done right what do you think? i think recursive message-code as rewriting could use an example :) (conceptual) hm well basically i'm just talking about having a message-call be potentially recursive 05:20pm that's established but doesn't say much more than "recursive message-code" yeah well i can't think of any instance where recursive messages are used in oolanggs perhaps elaborating where this particular recursion happens where, how, whatever appropriate bleh, research papers suck * eihrul/#tunes gasps. well it doesn't seem to be a problem to, within a message, clone the original method, bind arguments, and call that message oh the reason an example seems weird is that mutable object state makes the semantics a bit tricky 05:30pm yeah, academic papers really suck ok topic switch to? well i was thinking that the container-type objects used in slate would also be shape descriptions like how we discussed reifying references * eihrul/#tunes is not sure what water means by 'shape descriptions.' our objects themselves are sets, but it's not hard to make recursive list structures out of them well you have sets, arrays, linked-lists, graphs, collections and things like byte-streams How do you stream crap efficiently? these things obviously have 'state', but in general they're just containers atg: using objects that act as streams by spitting out the elements of the stream water fountains... 05:40pm the elements can be retrieved on demand by passing a message "give me the next one" to the object, which returns the next element of the stream of course, there should be many ways to access a stream like getting all mouse events for a time quantum eeek; producer consumer! =\ of course, there should be a good facility (i.e. in stdlib) for piping streams what's wrong with that? i don't see how accessing a stream would necessarily be limited to one type of organization hm piping streams sounds a bit like monads you could just as well augment a producer consumer with a publish subscribe :) roughly the same thing not necessarily but i would prefer a general framework push vs. pull * AlonzoTG/#tunes contemplates all the evil crap that I'll need to implement to make that work..... * AlonzoTG/#tunes contemplates how usefull re-directing the console stream was yesterday in DOS... or rather, pull vs. push ok so describe push in message-semantics an object registers (subscribes) with the stream to be notified of successive elements in the stream and the stream notifies (publishes) the element to all subscribers basically, event notification um message-semantics yeah well describe the message-passing and state required (i already grok events) n/m i'll do it * eihrul/#tunes shrugs. nothing too complicated, notification is just a message send subscription is handled through a collection of subscribers yes it can be very complicated can be built atop producer-consumer the problem occurs when you have a lot of messages being passed around in real-time due to a complicated event system and i don't think it works like "producer-consumer" at all rmm.. it can almost be an extension in pc, the stream receives the request for the next object(s) where the publisher is the consumer 05:50pm in push, the stream *sends* the object(s) as messages to the consumer exactly, you have the reverse relationship it's not an extension at all producer-publisher-subscriber, i don't necessarily see it as the reverse well, EXPLAIN with objcts and messages like anyone in oo does it well, the publisher directly requests elements from the producer stream and whenever its requests are answered, it then sends messages to all the subscribes with what was consumed from the producer this infers that the publisher is blocked on the producer that's not an extension that's piping middle-man :) well it's a hack * eihrul/#tunes shrugs. it's my opinion none-the-less i could really use a vacation from? me? work? both go for it but seriously we shouldn't need such a gap between stream ideas well, can the delivery mechanism be suitably abstracted from the producers and consumers themselves? you sound like you're talking about c++ this should be ridiculously simple * eihrul/#tunes shrugs. 06:00pm you make it ridiculously complex lol by requiring it to be reduced to message-passing? no by making an argument out of something that doesn't merit it :) * eihrul/#tunes is not quite sure why this discussion started anyway. well no one else seems to have anything to talk about (case in point, read the logs) hmm... I would like you to review the message passing systems in my OS when the next version of the specs come out in a few days... eihrul: so what shall we discuss then? dunno i thought so so how's the lisp code coming along? :) it will, i suppose -:- ult [noone@user-37kbash.dialup.mindspring.com] has joined #Tunes hold on a sec... i don't suppose you were thinking of streams implemented *outside* the language, were you? nope just making sure -:- SignOff Fufie: #TUNES (Ping timeout for Fufie[tunnel-44-37.vpn.uib.no]) so how would you try to unify the push and pull models? i think concurrency has been ignored too much as an issue and probably affects this question -:- air [brand@p0wer.qzx.com] has joined #tunes 06:10pm * eihrul/#tunes hmms. yes, concurrency is a big issue for push though, actually, no more than for pull when did richard stevens die? yes i think it affects them equally :) in fact, i think it helps unify them quite a lot, which is why i brought it up air: last year -:- lar1 [larman@1Cust130.tnt3.sfo3.da.uu.net] has joined #tunes water: will see if i can get to a rewrite this week... but as for now, have lots of stuff i'm behind on 06:20pm like school? not signifigantly okay, because school is important * eihrul/#tunes cackles. huh? high school so? $cholar$hips i'm not getting any, don't worry por que no? nor do i particularly believe i deserve them Eihrul is a rich punk. not quite, ult * ult/#Tunes grins so which is it? rich or punk? * ult/#Tunes slips a stiletto between eihrul's ribs.

Why? So I can go to collage. Why? So I can get letters appended to my name so people think that I know somthing about somthing. yes, that's the general point there Of course I should hope a good deal of learning also happens inthis proccess, but alas. Public schools in California are no longer somting to be proud of. well, learning could happen independently of a school given adequate materials which for the same price you will pay for college could be purchased 2**16 times over Independent study? Or totally without collage affiliation? book learning, dude Hmm thats still expensive (at least for a 14 year old) you're neglecting... in college, you pay for books *and* tuition *and* housing *and* food *and* other living costs True *and* for the piece of paper but alas, people want to ensure that you've wasted your $100k on that paper so they can feel safe Hmm Well as long as the parents pay for it ;) eh you're neglecting that you have to sit through lectures, take notes, exams, labs, papers, etc in addition to reading :P and not at your own pace i might add but the lowest common denominator But the idea is that all that is easy if you already know your shit so? why waste 4 years of your life sitting through 4 years of haze? 4 years is 1/20 of your life, dude Because, sadly, you need those appended letters if you wanna make it in life. (at least thats what they tell us) no don't confuse 'make it in life' with 'survive in pseudo-capitalist representative democracy' that's should be a crime to attribute our culture with life in general Yeah well if you don't survive in culture you won't survive in life -:- hcf [nef@me-portland-us734.javanet.com] has joined #tunes 06:50pm lar1: move to another country start your own take over one!

Know of any books/websites that are pretty good? I got ahold of this old school book and ugh! I was lost when they started talking about limits. Acccually worst then lost. One minute I thought I grokked it then next, I seemed not to. limits are -easy-. well, limit specifies a value that is approached but never reached eihrul: It can be reached eihrul: It just isn't necessarily reached no yes no it just so happens that the limit happens to coincide what could possibly be reached :P s/what/with what The limit can't always be reached... ( I don't think ) lar1: Correct so its just easier to say they all can't be reached eihrul: But some -can- be reached its just that sometimes you have a definition that coincides with the limit :P lim x^2 as x approaches 0 is a very simple example. not in my mental model :P no as x approaches 0, y approaches 0, (0,0) exists. Therefore, the limit exists. no Yes. that is what is approached you're confused what is approached with what is reached The approached point exists. you don't reach a limit! you approach it! that's why it's a limit Grr, the 'correct' answer for a limit problem is either undefined or an absolute there's no fuzzy area either that, or maybe i was just smoking some good crack while reading my calculus book The point either exists or it doesn't yes, but it's the point that is approached it's not the point that is reached the two coincide in some cases but sometimes they don't A point is approached by the limit. 07:10pm so it's easier to say that in all cases its the value that's approached! * ult/#Tunes cackles than to say that it is sometimes the value that is reached and sometimes it is not wtf are we arguing about? i dunno Ok, then perhaps differential calculus is a plot by fundies a limit is a point that is approached by a function of x as x approaches a given value. Do you know of any perticually helpful texts? lar1: your calculus book is fine.... easiest way to visualize limits is through graphs with holes The *limit* either exists or does not exist (depending on the continuity of thefunction at the point -- asymptopes &c won't exist, but removable discontinuities do exist) eihrul: No its not... Its Old School... [the book] ;) f(x) = (x - 1) * (x - 2) for instance if you graph that, you'll see holes in the graph er eihrul: Um, there's no holes there. f(x) = (x - 1) / (x - 2) brain fart :) Ok =) synaptic disfunction (Hey, power for the Psionicists in LispMUD!) as x gets close to 2 As X approaches 2, y approaches a point That will make hyperbolas, no? lar1: graph it, bust out a calculator However...I believe that function will give you an asymptope at x=2 Therefore the limit does not exist. lar1: You can't graph a true hyperbola on a calculator... lar1: f (2) happens to be undefined, but lim f (x) as x approaches 2 happens to be where that hole is Thats a funky ass hyperbola the hole is what is approached hmm but its not reached But if you have a function like x^2 which has no discontinuities Oh, its not a hyperbola at all or a function like x^2-9/x+3 where you can factor it out you can actually get a point a point that could be in theory reached (whether it exists or not, it could be reached if you followed that curve) ummm lim((x-1)/(x-2),x,2) is undefined according to its high holyness, the TI-89. er... wait my bad :) that's a non-removable discontinuity so yes, it is undefined :) Ok, I kinda said that. Why? It's an asymptope. With x^2-9/x+3, the limit exists because if you approach the point from both directions you will get a point (x=3) I should probly just read rather then pester you all... ult: well, technically, it is defined but with eihruls you wont because if you approach the point from both directions you get different points (infinity and negative infinity, I do believe) it's just what your definition of divide-by-zero hapepns to be Hmm * eihrul/#tunes wonders if we've signifigantly confused lar1 yet and contributed to the entropy of the universe. No, you haven't well, example: f (x) = (x^2 - 9) / (x + 3) at x = -3, you have a divide-by-zero you get a discontinuity in graph but it's removeable if you rewrite difference of squares here... f(x) = (x - 3) (x + 3) / (x + 3) = (x - 3) f (x) = x -3 has no holes, in particular 07:20pm so using that function, you can get the value of f (-3) whereas via the previous, you can't Whats the difference between removable and non-removable? that's the limit... in particular as x approaches -3 lar1: Removable means you can factor the discontinuity out of the function Nonremovable means you can't sqrt(x) is nonremovable when x < 0 non-removeable is where you have an asymptote or when it doesn't approach the same value from either side Ah, factoring! :) well, factoring such that a certain undefined point becomes defined likewise, 1/x is nonremovable because you can not factor the discontinuity out (It's an asymptope, you can never factor asymtopes out) lar1: Just keep in mind that the factored equation IS NOT THE SAME AS the original. lar1: It's only valid for that single point, if the problem involves additional steps, USE THE ORIGINAL. ult: Why not? lim (x / abs (x)) as x approaches 0 happens to be undefined for instance because on right side of axis its a line y = 1 lar1: Because as you should have learned in precalculus, you can't truly cancel variables out. You lose things. Period. on left side its a line y = -1 You lose critical points, holes, stuff like that. ult: Haven't taken precalculus. -:- rares [rares@wtrb-sh1-port46.snet.net] has joined #tunes doh :) lar1: Nor I. So your in the same boat as me. * ult/#Tunes had to learn this all the hard way too. hey wot was that equation ah Hola say you have f(x) (f(x) - f(x+h)) / h is the definition of a limit -:- SignOff hcf: #TUNES (Ping timeout for hcf[me-portland-us734.javanet.com]) I have no idea what that means, though, but that's what my book says at one point. Heh eh... In addition...you ought to look at delta-epsilon proofs. and that's what happens when you cross it the change in a function over a change in input physics analogy: For every epsilon there is a delta such that... the change in position over a change in time Those I *do* understand. or: the change in velocity over a change in time and its: [f (x + h) - f (x)] / h lar1: There is a coefficient for delta that will make delta equal to epsilon lar1: That coefficient is the limit or something. But it's not. The coefficient itself isn't the limit...but you get it from the limit... ;) eihrul: Whats h? h is just a variable. h = change lar1: building off of physics example: ignore. Just remember lim() on your TI89. startingPosition = position (time) endingPosition = position (time + changeInTime) ult: No, thanks. I want to grok this stuff ;) ult you'll never work on my future 3-D engines if sit around with a TI changeInPosition = endingPosition - startingPosition changeInTime? Bah, deltaTime ;) changeInPosition / changeInTime ult: I am familiar with delta well, i wasn't sure if he grokked the delta :) delta is so important to understand in calculus though. concatenated: if you don't grok it you ought to learn. calculus is simply the study of delta, delta being change. [position (time + deltaTime) - position (time)] / deltaTime for example, could be used to find speed Nothing more to it than that. heh. And to think people use calculus every day without knowiung it eihrul: Thats the definition of limit? rares: The most ironic part is that calculus could be taught in 9th grade. lar1: rmm, not quite :) Calculus concepts are -easy-. ult: And it should be!! and lisp in 3rd grade lar1: that's not necessarily definition of a limit, that's definition of a derivative The hard stuff is differentiating and integrating nasty equations. lar1: do you get the speed analogy though? lar1: change in position per change in time? But...a 9th grader could dx/dy y=x^2+4 easily. eihrul: Yes, I understand that. lar1: now where the calculus comes in... 10th grader could move up to general powers. lar1: if you wanted to find the speed when deltaTime = 0 07:30pm lar1: i.e. the instantaneous speed, the speed at a given point in time ult: They will let you do calculus in 12th if you are cool here rather than the average speed over a period of time Amazingly, S (S being symbol for integration on irc), S(Volume Function for a 3d Object) gives you Area Function for that object. lar1: They will let you do calculus in 12th if you are rich or popular here. lar1: you follow? :) Or, in my case, you are damned good at manipulating teachers. eihrul: I think so lar1: so you just use limits to do the icky work and get rid of the divide by zero cal culus the matrhematics of keeping your balance ult: Hmm. Need some manipulation lessons from you! ;) to find the instantaneous change in the output of a function aka derivative eihrul: How is that worked out? look in your book should be examples :) lar1 you need some parental manipulation and get some books either from a website or the library Ack, I just noticed a synaptic disfunction. S(Area Function) is Volume Function. Doh. unless it sucks * ult/#Tunes typed it backwards. ult: yeah, i was wondering :) eihrul: Well, too much effort is into reading these papers. eihrul: Yes it does suck, and its a libary book, which I returned. They rock! They totally bash fundie cult seekers. lar1: Pick up a physics book. physics is better at teaching calculus than calculus is. well duh Hmm, for all practical reasons I have only access to public libaray and community collage libaray. guess why it was invented lar1 there's a chance you'll find good shit on the net too libaray? You know I can't spell :) mu library oooooooookkkkkkaaaaaaaaaaaayyyyyyyyyyy What? * ult/#Tunes pats lar1 on the hea head. Young Jedi, soon you will understand the true nature of the Force.
