Hi, I'm writing a program in C++ and want initialize it with a configuration file. I usually use libconfig but in this case I have many similar configuration settings and in many cases it'd be easier to write the configuration file using basic progr... |

Lego turing machine
|
Hi,
A while ago I posted here about making a lego turing machine. In the end lego was too expensive so I used carboplast, popsicle sticks, plastic bottles, rubber bands and a glue gun. Here's the result:

I writing a basic ray-tracer and have a question about calculating the RGB values for each pixel. To calculate the color of each pixel we send a ray from the camera to the pixel, use the scene to find all the light sources that contribute to the col... |

using operators with polymorphism in C++
|
I have a Vector class that represents a vector which can have any number of elements. It overloads the obvious operators like + and -. I'd like to try different implementations of the operators so I was thinking of making an abstract vector interfac... |

Let's say I have the following function:
void addOne(double& x)
{
x+=1;
}
And I want to expose it to python using boost like this:
BOOST_PYTHON_MODULE(add)
{
using namespace boost::python;
def("addOne", addOne);
}

Are there any good open source numerical analysis libraries. Most importantly, I'm looking for one that can solve linear equations, solve ordinary differential equations, and efficiently handle various vector and matrix operations.
What do you... |

port forwarding

Is it possible to do port forwarding if my router doesn't support it? (I can't upgrade the firmware because it's not my router, and I can't switch routers because the router contains the modem from the ISP).
I was thinking that maybe it'd be possi... |

Hi,
Is it possible to write a program for a cell phone (in java ME on a Nokia phone for example) that lets you use the phone as a usb mouse? I'd like the computer to recognize the phone as part of the HID class when I connect it to the compute... |

Which is what std::vector is used for.
But what if I want to apply various operators to my vectors? Don't I have to write a new class to do that?

Why do you need more than one kind of Vector at all? Or at worst, more than a few small sizes? Are you writing some kind of quantum-mechanics simulator or something? Nearly all practical applications don't have to... |

using operators with polymorphism in C++

Thanks for all the helpful replies. It seems like I shouldn't be using polymorphism for basic types. Maybe it'd be better to use templates? I could make a class with a signature like:
template<class Storage, class Math> Vector;

How do the different implementations of your BasicVec differ? Are they different dimensions of a vector? Then you most probably want a compile time error anyway if you use two different vectors in an equation.

I'm sorry, I don't understand. How can STL and <algorithm> help with a mathematical vector class? (I now see that I wasn't clear before, I'm trying to implement a mathematical vector, not a container class)
