<0> :P
<0> should i say i still dont know how to configure windows too well?:)
<1> i can't configure either nor do i care that much, i just need my software running
<1> i still have a few particular programs that i've only running under windows right now
<0> yah.
<0> dunno i was surprised i managed to set all essential services at friend's kubuntu server
<0> www (apache+php+mysql)
<0> mail (postfix+courier+horde)
<0> of course ftp
<0> ssh
<0> stuff works
<0> breezy, but who cares
<0> http://www.prenosnik-servis.com/ that's his website for 'laptop repair'
<0> :))
<0> i didnt know i was any good at linux administration
<1> :)
<0> but looks like a year and a half of gentoo boosted my skills
<0> :))
<1> breezy even hang during the installation but dapper did much better now
<0> well that's not some exotic laptop stuff.
<0> it's genuine IBM xseries ....xeon 2.4
<0> it worked flawlessly
<0> xeon feels good, compiles a lot faster than my athlon xp
<0> damn i have theory exam tomorrow
<0> for 'numeric math'
<0> i wonder if i must memorize the formulas and algorithms:P
<0> bah
<1> good luck
<1> if you you need som practice/training :
<0> well i checked a collection of some possible questions
<1> Find all extremal points of f(x,y)=x*e^y+y*e^x
<0> mmm that's not what we have here
<1> btw how did you install java and netbeans on ubuntu ?
<1> via debian package or tar ?
<0> i tried to install java from deb, couldnt find repository
<0> then i installed from tar
<0> but i use gentoo for my java
<1> ic maybe i do that too
<1> do i need do deinstall the existing gnu java ?
<1> or do they get along fine ?
<0> well only one is in path, i'd say.9
<0> :)
<0> i didnt bother much with ubuntu
<1> oh ic
<0> i installed java in /home and just told azureus where to find it
<1> nvm then
<0> i use gentoo.. gentoo installs as many jdk's as u want
<0> then u set one for system (1.4)
<0> and for user let's say 1.5
<0> it sets PATH and CL***PATH for each
<1> well in theory that works for all distris i guess
<0> yes
<1> but in practice i had some trouble on fedora with that
<0> i had trouble with fedora with many thing
<0> that's why im on gentoo now
<0> gentoo works:P
<1> haha
<0> rpm is stupid and i doubt deb is any better
<0> problem is... if you install a lib from source
<0> rpm wont know about it
<0> it pissed me off
<2> that's why you're supposed to build a deb
<2> or an rpm
<1> you expect too much
<2> that fulfills the dependency
<0> jottinger: i know.
<0> jottinger: but...
<0> :)
<2> but what? It's freakin' trivial
<0> sure:)
<0> dunno source dist is more fun
<1> jottinger : nothing is trivial (aside from saying something is trivial)
<0> that's first word i learned at linear algebra
<0> "trivial"
<0> :))
<1> wolfey : lol
<1> brings back memories
<0> professor said it's trivial
<0> well almost all of us just stared at it
<0> :P
<1> the cl***ic is a prof thinking hard for a while whether something is trivial or not :)
<1> and then saying yes it is actually trivial
<0> well all things are trivial, when u master them:P
<0> java painting is trivial now. and i remember how many nerves i lost:)))
<2> haha
<0> what'ya think about http://www.wolfey.si/azimut.jpg
<0> is it any good?
<3> there has to be a better way to do this...this is just butt ugly!
<3> http://pastebin.ca/68429
<3> hmm, and there's a bug
<0> well for precision... if Math.abs(re1 - re2) < Math.pow (10,-precision)
<0> i think?
<3> hmm, yes. that should work well I think
<0> and same for im
<3> although it constrains the test to only after the decimal I think
<3> still, I can live with that, and it's nowhere near as ugly as what I came up with...thanks :)
<0> had to study this
<0> :P
<0> smsie: you can also subtract the number of digits
<0> before dot/comma
<0> i'd guess (int) (Math.log(re)/Math.log(10)) should return number of digits before '.'
<3> wlfshmn: yeah, my tests just showed that you have to...
<0> For any positive real numbers x, a, and b, where a 1 and b 1:
<0> http://www.okccc.edu/maustin/Eval_Logs/Evaluating%20Logarithms.htm
<0> search for 'change of base'
<0> or
<4> smsie: poor aim? ;)
<3> ?
<4> (18:44) < smsie> wlfshmn: yeah, my tests just showed that you have to...
<3> ah, yes, sorry
<3> ah, need to add 1 to the log change
<0> smsie: so any luck?:)
<3> wolfey: just trying to get the number of digits exactly correct. It's off by one
<3> digits before the . I mean
<3> sine log_10(1.99)=0.3(ish). I need it to be 1.something
<3> s/sine/since/
<3> hmm, okay, that *looks* right
<3> but still the JUnit test fails...
<0> hehehe
<3> http://pastebin.ca/68435
<0> i think you first check the number of digits before .
<0> for both
<0> with this log stuff
<3> hmm, only have for the real, not the imag.
<3> although (for this test) it's the same in either case)
<0> smsie: i mean if you say total digits, you mist first check the whole part of both numbers
<3> wolfey: that was when I was convertting to strings. I didn't want the h***le of worrying about where the . was. precisaion after the . is fine
<3> the numbers aren't expected to be much greater than 2^10 anyway
<0> hey
<3> ah
<3> I see a potential problem...
<3> ah, no, I don't :)
<0> i think something else
<0> look
<0> you can either multiply or divide by some common factor.
<3> hmm, then cast to an int and compare?
<0> well this < Math.pow(10,-precision) works for abs(..) < 1
<3> casting to an int truncates ISTR?
<0> so if you find the whole part of both numbers
<0> and divide both numbers by 10^max
<0> both are < 1
<0> 'normalize'
<0> u know
<3> not really :)
<0> well you know float is 0.1xxxxxx * 2^exp
<0> that's normalized form
<3> oh, is it?
<3> I hadn't known that
