Is there a cross platform way to get the monitor's refresh rate in python (2.6)? I'm using Pygame and PyOpenGL, if that helps.
I don't need to change the refresh rate, I just need to know what it is.
I am not sure about the platform you use, but on window you can use ctypes or win32api to get details about devices e.g.... |

I like Python, a lot. I'm one of those people who would use it all the time if they could, especially for web development. Which is convenient, since I'm currently working on my own company.
One of the drawbacks of using Python, though, has always been getting it to play nicely with web servers. I'v... |

In my main script I import

The LV2 documentation generation tools use RDFLib. It is probably the most popular RDF interface for Python, though does much more than just parse Turtle. It is a good choice if performance is not an issue, but is unfortunately really slow.
If you need to actually instantiate and use plugins, you probably want to use a... |

I am just wondering how the buffers work on a com port.. The code below is a snip of how I am reading a com port. I am wondering if by doing serial_connection.close() and serial_connection.open() I would be losing any data, or would it remain in the buffer? You might ask why I am closing and opening the comport.. The r... |

Is there a closed formula to the problem $f(1)=1, f(2n)=f(n), f(2n+1)=f(2n)+1$. So far i have found a solution for $n$, which is the number of power of $2$'s needed to add up to the number starting with the greatest power of $2$. Also $n=$ the number of $1$'s needed to represent $n$ in binary form. So for example $f(12... |
