Comments:
<0> you should have
<1> I've been to busy looking thru my philosophy textbooks
<1> lol
<1> thanks
<0> we showed you how to read your data
<1> oh
<1> no
<1> that question I finished
<1> this is another question
<0> ah
<0> uh-oh
<1> this one is easy
<1> its the last one too
<0> I think I'll go back to bed and catch a Z or 3 before going to work
<1> lata
<0> the easy ones are the killers
<2> yeah it seemed like you were up early vawjr, heh
<0> rdragon I wasn't feeling well early last evening so went to bed around 2000 .. .woke up around 0230 thought I'd catch up on EMail and stuck my head in here (mistake)
<2> ah, hehe
<3> g'nnght
<2> 'night
<4> good night, vawjrZZzz-
<5> anyone around?
<6> no
<2> no
<5> Given 0 <= Y/Z <= 255, and X = (Y * 2^(Z*4))... I have X and need to find the best fit for Y/Z to approximate X, anyone have anything for me to lookup or any idea how to go about this?
<6> maybe when someone's around
<6> BTW, anyone *is* in #hadess and #eneida
<6> so maybe you should ask there :)
<7> TechRaven: never had a course on numerical solving methodS/
<7> ?
<7> shoulde be a standard CS course
<5> mathieu: I've done it before, but its been sucha long time
<2> ...software development "in test"... what does "in test" mean?
<8> i have what seems a simple problem to solve but I am being dumb. I want to implement an n-digit counter where each digit has a value between 0 and m. should i solve this recursively? and what do i need to p*** round each iteration - an array containing the position of each digit?
<9> huh? so you just want to store a sequence of ints?
<9> just use a vector<int> if thats the case
<10> anyone knows how to change baudrate for a specific RAS Entry?
<2> baud rate... haven't heard that in a couple of years, heh
<10> yeah i know it sounds weird ;)
<10> have to connect to gprs modem
<2> not in properties somewhere?
<10> cant find it
<11> Off to office
<12> hi, in whic situation shoul i use struct pointers inseat of using normal structure variables?
<13> Well, in case of polymorphism, amongst other things.
<13> If you're dealing with a C API that uses them, too.
<12> DrkMatter: can you pls give an example?
<13> IF you want to share the same structure amongst multiple objects, you'll need pointers, too. The smart kind, if possible.
<13> Well, I'Ve jsut given two examples. o_O
<13> The windows API use struct variables that you ahve to p*** through pointers.
<13> And I'm sure you can think of an instance of polymorphism.
<12> thanks!
<12> i got it
<14> can some one explain a ^= operation to me?
<14> a ^= b
<15> ^ is or
<16> ^ is xor
<14> ok. so it's conditional?
<15> so which bit is giving you problems?
<9> no
<15> xor right
<14> xor ?
<9> exclusive or
<14> well, what is ^= called? the orequals operator?
<14> what's that do, is really my question.
<15> its a shorthand for a = a ^ b;
<9> same as += is short for a = a + b
<14> so "raised to the power of"
<9> thats a += b,
<9> no
<9> exclusive or is a bitwise operation
<17> t1m: do you know what xor means?
<14> this is bitwise, yes.
<14> xor, no.
<14> what's it mean?
<15> if any bit is 1 the result is 1
<17> ok, so we have a communication error it appears
<9> do you know what OR does?
<14> thank you bealtine. i remember that now.
<9> no its not,
<17> do you know what mod means
<17> modular arithmetic
<9> its if ONE and only ONE bit is = 1
<14> i read that on a web page i remember.
<9> in xor if both bits are = 1 then the result is 0
<16> t1m: http://computer.howstuffworks.com/boolean1.htm
<14> i think i understand |= just fine
<17> it's addition modulo 2, if you know what that is
<9> thats why its "exclusive"
<14> does |= also set as 1 like the ^ does?
<17> no, that's a regular or, non-exclusive
<17> so 1 | 1 = 1, but 1 xor 1 = 0, since both are set
<15> 1 xor 0 = 1
<14> ok. i need to go look up xor now then. heh
<17> aye
<14> thx.
<17> http://en.wikipedia.org/wiki/XOR
<14> oh, one more question
<15> xor is often used in cheap and cherrful checksums
<17> cheap and cheerful? hehe
<14> if i have a struct and use it with char *struct_name, what then is the purpose of something like char **struct_name (with two stars now)
<9> a pointer to a pointer
<9> like a 2d array
<14> like char array[20][20]
<15> sort of ...but its very C
<14> gotcha.
<14> why would a link list need to point to a point
<9> to point to whatever its linked to
<9> oh wait sorry
<9> i have no idea
<14> i'm trying to see the functionality of using **
<14> heh nnp
<9> what you're doing all sounds very "C". The STL will take care of all that kind of nastiness for you
<14> how about this.
<9> (you should still understand that stuff but in practice i havent found much use for ** )
<14> what can I do with ** that I can't do with *
<14> you're right, so many things are all included for us lately, i don't know the skeleton of what i'm doing half the time
<15> http://www.noidea128.org/sourcefiles/15921.html <- look at that
<14> arr.. streaming integers ?
<15> eh?
<14> i don't understand int *i;
<14> let alone int **i;
<15> oh well
<14> well, just on integers
<14> i mean, does * change the integer var somehow?
<9> do you know about pointers?
<14> somewhat.
<9> if not i suggest google
<14> i know how to initialize them and set them to next, etc.
<15> google pointer tutorial
<9> well you cant "kinda" understand pointers. You either do or you dont. I recommend getting a book on c or c++ or googling
<9> if you dont know what int *i is then you dont understand pointers at all ;)
<9> it simply says, i is a pointer to an integer
<14> so can i using boolean if statements on a *int?
<12> anybody understands this..
<12> SceneNode *node1 = mSceneMgr->getRootSceneNode()->createChildSceneNode( "RobotNode" );
<13> Hm. Would the GoF book be something relevant to add to my technical library?
<2> yes
<2> newtoogre - looks like it came out of Ogre or Irrlicht
<2> or any scene graph library i guess
<12> yep, but could you understand the line, =)
<2> what's the problem?
<2> what's to understand?
<12> there is two ->
<2> so?
<12> never seen anything like that
<2> mSceneMgr is likely a pointer, and getRootSceneNode() likely returns a pointer too
<12> oh
<12> ****, =)
