Hello all, I need to make a program that will allow a user to rotate and translate a molecule (using the mouse) so as to bring any given atom of that molecule (or plane encompassing a number of atoms) to the X-Y plane (i.e. the Z component would be 0). I cannot find appropriate modules to allow

Hi, In C I have seen some programs such as kismet etc where c programs could be written to get the SS from the card. The idea probably is to read the prism 2 header from the driver. This I guess is a bit more lower than the "raw socket" where we can get the MAC layer frame. The prism 2 header giv

How would you get it with C? Based on this, we can know if it is possible with plain Python (and not writing a python module written in C) Do you do this with a library call? or maybe using FCTL or IOCTL? I have done IOCTL in python and it is quite easy, but some provisions have to be taken res

If you use something like this: for line in file.readlines(): then line is a string to the next newline and it automatically detects the EOF and the same with file.readline() but that will give you one character at a time.On 7/19/05, frank h. <[EMAIL PROTECTED]> wrote: hello allI am trying to wri
