I have a simple web server written in Twisted, and I'm trying to start it up daemonized with twistd. Everything works fine with reactor.run() but when I use twistd -y (as root), none of my packages which are in direct child directories get found. I'm running twistd as root, since the server runs on port 80. The manpage for twistd says: ...
Hello. I'm trying to convert images taken from a capture (webcam) and do some processing on them with OpenCV, but I'm having a difficult time.. When trying to convert the image to grayscale, the program crashes. (Python.exe has stopped working) Here is the main snippet of my code: newFrameImageGS = cv.CreateImage ((320, 240), cv.IPL_D...

I was asked to write a Perl-to-Python and Perl-to-Ruby (and vice versa) code translator by an evil boss, and therefore I'm curious to know if some automatic code translators between them exist already. Just by googling it, I found Perthon, plus endless discussions and dead projects trying to do this. In your opinion, is there a standard...
Hi, I have to deal with a large result set (could be hundreds thousands of rows, sometimes more). They unfortunately need to be retrieved all at once (on start up). I'm trying to do that by using as less memory as possible. By looking on SO I've found that using SSCursor might be what I'm looking for, but I still don't really know how...
Hi I have a set of unicode numbers , I need to convert them to UTF-8 and print the result in to split them in to hex values. eg: Unicode 0x80 should be converted to UTF-8 and printed as (0xc2,0x80) I tried following str(unichr(0x80).encode('utf-8')).split(r'\x')[0] But it does get split in to ['c2','80']. But it gives me ['\xc2\x80...

According to this answer: http://stackoverflow.com/questions/1020892/python-urllib2-read-to-unicode I have to get the content-type in order to change to unicode. However, some websites don't have a "charset". For example, the ['content-type'] for this page is "text/html". http://bit.ly/6IcCtf/ I can't convert it to unicode. encodi...

I guess this is kinda abusing the feature, but I'm still curious whether it could be done - I want to do something like: with conditional(a): print 1 so that the print 1 part is executed only if a==True. Is this possible? EDIT: Like people state below, this is horrible style. It's just a riddle\question. Don't try this at home, n...
Hi, I'm planning on putting a store's inventory on a Drupal site and I'm wondering if it's possible to create a script (maybe in python/php?) to enter the data automatically to Drupal with CCK? Thanks in advance! ...
Is there an algorithm that checks whether creating a new thread pays off performance wise? I'll set a maximum of threads that can be created anyway but if I add just one task it wouldn't be an advantage to start a new thread for that. The programming language I use is python. Edit 1# Can this question even be answered or is it to gener...
I've got a Python module with docstrings in class methods, and a real-world example in the module docstring. The distinction is that the method-docstrings have been carefully crafted to be utterly repeatable tests, while the real-world example is just a copy'n'paste of the history from a Linux shell - which happened to invoke the python ...
Hi, We have an existing C# project based on NHibernate and WPF. I am asked to convert it to Linux and to consider other implementation like Python. But for some reason, they like NHibernate a lot and want to keep it. Do you know if it's possible to keep the NHibernate stuff and make it work with Python ? I am under the impression that...
Suppose you open a file, and do an seek() somewhere in the file, how do you know the current file line ? (I personally solved with an ad-hoc file class that maps the seek position to the line after scanning the file, but I wanted to see other hints and to add this question to stackoverflow, as I was not able to find the problem anywhere...

Hi all, I am looking for a library to get some information from the active windows. By "information" I mean the absolute/relative position of the window, the size, the list of all the windows. There is a function in GTK+ called get_window_list_toplevels() or get_root_window() but I get only the windows information realized with GTK. I...
