Hi!
I have an application where images (jpeg) have to be annotated by an
operator. I use PIL like:
import Image
im = Image.open(Path)
im.show()
raw_input(Path + ':')
Python runs in a console window. Then show starts some application (in
my case Windows picture and FAX viewer) and the

Yes!
Python uses auto garbage collection. As soon as the object reference
count becomes 0 it is removed from existence. So the problem typical
for C/C++: accessing pointers
to already deleted objects does not exist in Python.

1. Why not to simplfy the problem. You can extract values from the
dictionari in python (this is fast). Put them in a list (fast). Pass
the list to the extension, handle it and return to python. etc.
2. Use Pyrex.

The linear method:
You create an array - one bool per minute. For one day 24 * 60 entries
is enough. Spans (Start, End) are in minutes from midnight. Set array
slots in range(Start, End) to True for each input span.
Scan the array and find metaspans - contiguous sequences of False.

I'm using windows 2003 small business server and I want to install my
python programm as a NT (it's just an old name) service. Does anybody
know how to do this?
1. you need win32 extensions installed;
2. you need py2exe (optional if you want to install the service on the
machine with no Python)
Starting a process on WIN98 is VERY slow. (On NT much faster the second
time). If you really want to use WIN98, modify CGIHTTPServer.py in such
a way, that branch
#Other O.S. -- execute script in this process
is executed.
This way CGIHTTPServer is as fast as it gets. At least not slower then

I doubt that the recipe you recomended will work at all in the case of
different processes. To do this right file has to be open in shared
mode (by both programs). Python does not support shared access.
In the case of one program, but different threads probably this will
work.
