<0> little thing we like to call, the rounding problem of floating points
<1> im guessing its pow
<0> floating point precision and integer truncation leads to this
<0> ok, gotta leave for dinner, free meal at clyde's, mmm
<1> so how can i fix it?
<2> Instead of casting to int, round
<2> Or add a mulligan before casting, like .00005
<2> Just to tweak it over the .00000 threshold before truncation
<2> Or stop using dev-c++ if you have vc++
<3> how can I make a new int array with the same size of another already defined and I get the pointer to ?
<3> and hi
<3> got: int *new;
<3> and int *old;
<3> do I use memcpy(new,old,sizeof(*old)); ?
<3> but that gives segmentation fault
<2> Gotta allocate memory for it, first
<3> ok
<3> then I won't be needing memcpy after all
<1> how do u know if a variable inside a function has a default value or not
<4> KBM you give it one :P
<4> if someone then explicitly sets that variable to the same default value, you have no way of knowing how it was set just by looking at the value
<1> if(piErrChk != NULL) *piErrChk = -1;
<1> piErrChk is a int *
<1> this is its funtion - int StrToInt(string sSource, int *piErrChk = NULL)
<5> What's that for a dumb function
<1> nm
<1> i got it
<6> is there a way to look at the actualy binary of a float?
<7> reinterpret_cast
<7> get Thinking In C++, warez edition online, look up how this typecast <reinterpret_cast> works
<8> !list
<9> warez edition?
<10> warez? I thought it was free
<9> Why not get the author's edition online which is free?
<10> i guess warez is their first stop before google
<9> heh
<5> union { unsigned int i; float f; };
<5> (***uming our ints are the same size)
<5> +y
<11> I am thinking of a web service which is calculation intensive (does optimization with some constrints). What do you think will it be more faster to use cgi with c++ or jsp
<11> any recommendation?
<11> it is said that jsp is more scallable . does it right?
<10> said by who?
<5> I certainly wouldn't use CGI
<10> how 'calculation intensive' is it really?
<11> it use ismplex methods and genetic algorithms for optimization
<11> actually scalebale part is what I read from web
<11> ashe:why wot you choose?
<11> cgi
<7> genetic algorithm, mmmm
<12> Hey
<12> What are you guys and gals working on today?
<7> Hello
<7> Need some real hacking, but i'm in bad mood, working alone is starting be stress me a bit :-|
<13> trx, I know hwo you feel
<7> utter a **** private and we can finish complete web-vulnerabilities detection tool (sql, includes, overflow, fmt....), or we can try hard to fool exec-shield....or we can audit some source code (working on webDAV module for apache....just sniffing for vulnerabilities)
<7> :-)
<7> if you wanna cooperate on cool project, choose me, please :-)
<13> hehe
<7> ;-
<7> )
<13> you develop webDev?
<13> webDav
<13> even
<11> trx: what do you recommend?
<7> webDAV. it's protocol for web authoring and managing webs generally
<7> blueman_x the sql/injection tool for detection of vuln in web application....
<11> cool
<7> i think so, but this is C++ channel. I'll use python...eeek ;-)
<11> I am thinking of making a optimization web service (you give some constraints and solves it) would you recommend c++ with cgi or jsp or another way which promises a good performance
<7> i'll change variable content to server side scripts like PHP and let the server eat it....i'll look at the result, sniffing for anomalies (error messages, 50x server messages and so....) :-)
<7> Ok. It's not a "platform" i know much about (JSP), no comment :-|
<7> CGI is slower generally that apache modules for PHP, Python and so....
<14> yo!
<7> But the speed isn't mostly an issue....though i have no idea what you want to program :-|
<7> that/than
<7> I think i'm ripe for sleeping :-|
<14> can anyone help me ? i need a some onformation
<14> *info
<11> trx:thanks anyway :-)
<14> in american internet, where i can get a good freelance jobs ?!
<7> blueman_x i'm so sorry........:-
<14> pls help
<7> (
<12> Hey, guys, I can't display the sourcodes from the site...
<12> Is there a problem with the website right now or?
<7> Xyppher maybe the server executes the source and send output to you....;-)
<7> :-(
<12> Heh
<7> i'm so sorry.....
<12> I don't think so...
<7> :-((
<12> Error: window.parent.frames.main has no properties
<12> Source File: http://www.noidea128.org/sourceinput/input2.php#
<12> Line: 20
<12> That's the java script error I got.
<7> No properties? I don't think it's an object....maybe it's ex-object or object which never existed in your program
<7> sorry that i speak so vaguely
<7> for me, no properties == it's not an object
<7> :-|
<7> or isn't it: window.parent.frame.main ?
<7> window.parent.frames.main looks crazy for me :-|
<12> well, trx, can you just test the site out and let me know if you're loading the codes
<7> Or can anybody show me object with no properties? encapsulation of functions? looks like an wierd approach in so called "OOP"
<7> Xyppher i'll try to help you...
<11> trx: good luck with your project
<12> Sure, trx...
<11> I found a good site for solving optimization problems I will look at it http://neos.mcs.anl.gov/neos
<7> Xyppher i think it works....inspection your input...sometimes i get: DECLARE ERROR!
<7> Xyppher on some special username contents (on lookup) i get : DECLARE failed!
<12> Heh... it's my browser...
<12> not sure why firefox would choke on this...
<7> Hey! It works here...
<12> correction... now it's working
<7> At least i think your scripts work...i mean, execution :-)
<12> something must have been on a break...
<7> I was looking at http://www.noidea128.org/sourceinput/input2.php?username=&comment=
<15> Hi, I'm writing a little program that input a number (between 1 and 4) and increment the value in an array (it calculates the number of 1, 2, 3 ect. entered) until the input is 0. but I get a funny error when the loop stops... I've posted my code there http://www.noidea128.org/sourcefiles/15851.html
<7> mast` huh, what is this? results[answers - 1]++;
<7> seems like an semanthic bug...
<15> bah, since I enter a number between 1 and 4, and the array goes like 0, 1, 2, 3
<15> I substract 1 from the number inputed to get the good array position..
<7> what about something like (*results[answers - 1])++; ?
<15> what does (* ) do ? :/
<7> dereference
<7> i'm not sure about the brackets ()
<7> it changes the priority....some C++ guru, advise us :-)
<15> Let me try
<10> i missed the question
<7> i can try too....
<16> it means that you dereference before you incremenet
<17> People! Please give me some links to good programming forums and freelance sites ?
<16> in other words, you're incerementing the object it points to
<16> whereis if you didn't have the () you wuld be incrementing the pointer
<18> cn28h did you finish your education yet?
<16> nope
<15> it gives me an error, "invalid argument"
<10> mr_killer try monster.com... this isn't a job resource
<12> whose code is this?
<12> mast` ?
<16> if things go the way I hope, I won't be done for about 7.5 years
<15> yes
<10> cn28h what are you in school for?
<19> hmmmm...
<16> right now I'm in for CS and Math
<12> you're talkinga bout the first look, I take, right, mast`j?
<7> mast` dude, it works
<16> but, I'd like to enroll in a PhD program
<7> mast` your code works and i'm stoned
<15> without the (*) thing ?
<16> the one I'm shooting for takes an average of 6 years to complete
