<0> rdragon: even if you stay 2 years it's better than throwing 24x $1000
<1> i think i might go to law school
<2> rdragon: I need something simple to use, don't need crazy XML capabilitys
<1> if i am going to put up with this ****, i might as well make 5x what i make now
<0> TechRaven: tinyxml is simple
<0> And it has only basic xml stuff
<0> (hence "tiny")
<2> coo coo
<3> hello
<0> I bet it's < 1000 lines
<4> tinyxml is basically a parser, and not much else
<4> I think it's 1 or 2 files, even
<1> SAX?
<3> ashe, are u familiar with eigenvectors?
<0> Sadly
<4> oh good, it's dextre1
<3> haha
<3> c'mon, it's not so bad to see me right
<4> heker - yeah, but big deal - it forces you to write your code better, really
<4> heker and it doesn't look like that much of a h***le
<1> argh
<3> does the polarity of an eigenvector have any meaning? since.. the sign of the eigenvalue already tells u which way it points..
<5> yah i guess
<5> can live with it now
<4> heker you could probably write 1 or 2 regex replacements to change that code, too
<5> like?
<5> erm regex
<4> like replace that #include ***ert_is_same line with the two #include lines
<4> and replace that macro with the new one
<6> dextre1: the direction of eigenvalues is insignificant imho...
<0> dextre1: nope
<6> like you could multiply it by -1 and still have an eigenvector...
<5> yeah gotcha
<3> are eigenvalues always positive?
<3> drahflow: yeah, that's how i figure
<5> sweet thanks
<0> And eigen values can be negative
<6> yeah...
<6> meaning that vectors pointing that way will be inverted by the transform (and scaled according to the absolute)
<3> but even when they're negative.. it doesn't really matter right?
<6> no
<3> only direction and scale matters.. and that's given by eigenvector and eigenvalue, so.. how the eigenvector is flipped between its 2 polarities is inconsequential
<6> every scaling of the eigenvector with a non-null scalar is inconsequential
<3> gotit
<3> thanks guys . u 're awesome
<3> my eigensolver is spewing out eigenvectors with funny signs.. sometimes right, sometimes wrong
<3> i'm using mathematica as a reference
<0> Why do that when you could be browsing porn
<3> hey! i said leave my porn out of it
<3> to me it seems like the eigenvector polarity is quite arbitrary
<6> what do you mean by "wrong signs" in the first place?
<7> scalar is -ve or +ve
<3> well.. to make sure i implemented it correctly. i checked my solver against some test cases i found online.. produced by mathematica. and there's these small discrepencies
<3> it bothers me a little that i can't get the same exact output..
<3> the signs for the eigenvectors i get. are correct, except some are flipped +/-
<3> it's very arbitrary. the terms within each eigenvector is correct.. but only correct if the whole eigenvector is flipped to the correct polarity
<6> which is nothing bad... as I said, scaling by anything which is not 0 is inconsequential...
<3> cool cool
<3> i didn't use anything non-deterministic in here. so i wonder if i did anything wrong
<8> used a different algorithm ?
<3> yeah.. theirs is faster :P
<3> and they deal with complex eigenvalues.. which i have no clue
<3> what it even means
<7> Sheesh did you sleep through your linear algebra cl***?
<0> At least he uses some of it, IRR ;)
<7> what
<0> What's your PhD about again?
<9> http://www.theonion.com/content/node/45357
<7> Formally modelled Architecture Description Languages
<0> See
<0> Even his eigen values sounds better
<7> Eigen value is a little concept
<9> Formally modelled Architecture Description Languages...
<7> Which one could explain in 5 minutes
<9> WHAT???
<9> IRR
<0> Like UML can't be explained in 5 minutes
<9> explain your PhD topic in summary
<9> as in 2 lines of text
<9> come on
<9> do it
<0> He can't do that
<0> He'd have to mention UML
<9> hehe
<7> There is recent work in modelling ADLs in UML
<9> I can explain my PhD in 2 lines easily
<7> But I think its sort of a dead end
<9> whats ADL?
<0> archi desc lang
<9> oh
<7> Architecture Description Languages
<9> lol
<9> what are those?
<9> explain!
<0> So he just told you his title, but another way
<9> 2 lines
<7> I just explained my it above dude
<0> "explain Formally Modelled Architecture Description Languages"
<7> What part of Formally modelled Architecture Description Languages you don't understand
<9> any
<0> "alright.. two lines.. ehm... formally modelled ADL, there, explained"
<0> You could add FM to it
<9> Formally modelled is what? logic?
<0> It'd sound like radio
<7> Formal == a process calculus Pi-calculus
<9> thats cool
<9> ok
<9> now
<9> ADLs?
<7> Don't you know anything about software engineering?
<7> Do you know what a software architecture is?
<9> no
<9> its ambiguous
<7> Do they teach anything besides ignorance in Imperial?
<9> explain what you think ADLs are
<7> Man you are putting me in a bad mood
<9> IRR, I dont mean to attack you
<7> Software Architecture == High level specification of a software system
<7> ADL == a language that is used to define architectures
<0> Quantum``: he's always like that, that's how idiots try to defend, they attack
<0> That's why JB keeps arguing too
<9> so you want to model software with pi calculi?
<0> It's all linked
<7> The ADL I am working on also addresses implementation details
<9> IRR
<7> no
<0> IRR should do a PhD in marketing speak
<7> using an adl that formally founded on Pi calculus
<0> He said 2 lines and that's already 25 lines and you didn't explain anything
<9> I still dont get it, its not specific enough
<7> MrAshe because you and I don't speak the same language
<0> Well, you said 25 times ADL
<9> you want to model software architecture using pi calculi?
<9> if not, explain better
<7> Quantum`` you can read one of the foundational papers
<7> I can't type it all out over here
<9> all I asked was a short explanation
<0> What will you put on the first page of your paper?
<0> Like, first paragraph
<0> (I don't mean the "I dedicate this to my gay lover, Edouard")
<7> My paper is not about the core subject, but let me paste it
<0> I bet it'll contain plenty of "ADL"
<9> okidoki
<9> MrAshe... :)
<7> One thing you could learn MrAshe is that we have a thing called an Abstract
<7> Do you want me to explain that to you?
<7> I can do that in less than 2 lines
<0> That'd sound too much abstract to me
<9> IRR, me and ashe wanted you to tell us the abstract
<9> we didnt want to read it on a paper
