I am trying to send out an ARP request with python, working with dpkt, and I found some sample code that uses: socket.socket(socket.PF_PACKET, socket.SOCK_RAW) I understand that you need to use raw sockets to send this, but it says that socket.PF_PACKET doesn't exist. And there is nothing in the python docs about it that I have seen. ...
I have been using MATLAB for my work, but I have started learning Python lately. I employ statistical analysis, more precisely geostatistics, in my work.

I've taken to putting module code directly in a packages __init__.py, even for simple packages where this ends up being the only file. So I have a bunch of packages that look like this (though they're not all called pants:) + pants/ \-- __init__.py \-- setup.py \-- README.txt \--+ test/ \-- __init__.py I started doing this because...
I recently read Eric Steven Raymond's article "How To Become A Hacker" and I like his suggestion of learning 5 key languages (he suggests Python, C/C++, Lisp, Java, and Perl) as a way of covering the main programming paradigms in use today. His advice is that it's not so important which specific languages a programmer knows. It's more ...

I'm wondering if it wouldn't be a better if Python would store the compiled code in a file stream of the original source file. This would work on file systems supporting forks/data-streams, and fall-back if this is not possible. On Windows using ADS (Alternative Data Streams) On OS X using resource forks On Linux using extended file at...
