Well just getting into the flow of thing with Python. Reading a few books, finding it fairly easy as I already have some experience with C++/Java from school and Python is definetly my favorite thus far. Anyway, I am getting a whole bunch of information on python, but haven't been putting it to much use. Thus, what I was wondering was i...
I'm reading in a binary file (a jpg in this case), and need to find some values in that file. For those interested, the binary file is a jpg and I'm attempting to pick out its dimensions by looking for the binary structure as detailed here. I need to find FFC0 in the binary data, skip ahead some number of bytes, and then read 4 bytes (...
My app needs to do some privileged work. I've been looking everywhere, but I can't find anything useful. I know I want to use Policykit1 and dbus because all the other alternatives I've found aren't used anymore. This is the code I got so far: import dbus import os bus = dbus.SystemBus() proxy = bus.get_object('org.freedesktop.PolicyK...
Hello, I tried to send SYN packets on my local network and monitoring them with Wireshark and everything works just fine, except when i try to send a packet to my own ip address it "seems" to work because it says Sent 1 packet, but it is not really sent, i can't see the packet in Wireshark nor any answers to the packet.

With reference to another case of pretty much the same question I have, Brightside asked: http://stackoverflow.com/questions/2264157/library-to-render-directed-graphs-similar-to-graphviz-on-google-app-engine The accepted answer was "canvis", which looks very cool from a rendering perspective, but canvis just does the drawing. It still n...

I noticed that the Python 2.7 documentation includes yet another command-line parsing module. In addition to getopt and optparse we now have argparse. Why has yet another command-line parsing module been created? Why should I use it instead of optparse? Are their new features I should know about? ...
I have written a function for adding emails to newsletter base. Until I've added checking validity of sent email it was working flawlessly. Now each time I'm getting "Wrong email" in return. Can anybody see any errors here ? The regex used is : \b[\w\.-]+@[\w\.-]+\.\w{2,4}\b and it is 100% valid (http://gskinner.com/RegExr/), but I may ...

I have some simple code that represents a graph using a square boolean matrix where rows/columns are nodes and true represents an undirected link between two nodes. I am initializing this matrix with False values and then setting the value to True where a link exists. I believe the way I am initializing the list is causing a single boo...

I am using a re.sub callback to replace substrings with random values, but I would like the random values to be the same across different strings. Since the re.sub callback does not allow arguments, I am not sure how to do this. Here is a simplified version of what I'm doing: def evaluate(match): mappings = {'A': 1, 'B': 2} re...
