Re: Anyone use GD with pyhton?
On Friday 08 December 2006 16:17, jeff wrote: > could somebody explain to me how to install (or compile) GD for linux, > so that it works in pyhton? Jefff, the gd-library's website is at http://www.boutell.com/gd/ and they have a link there for download as well. It is highly likely that your linux distribution already has a gd library package ready to install. Use your package manager to search for 'gd' and you should get something. Now that you have that installed, you will need to get the python binding to it. A quick google search revealed gdmodule @ http://newcenturycomputers.net/projects/gdmodule.html Hope this helps, Jonathan -- http://mail.python.org/mailman/listinfo/python-list

Chris,
I googled for {xlib caps led} and the first link was to a forum post:

The third post down, the guy made a program to set the LED of his scroll lock
key. The C source is at http://members.optusnet.com.au/foonly/hddled.c
If you can manage to convert his code into python w/python-xlib you will be

Re: Strange return value from SOAP call
Toby, Strange stuff, I just tried it out myself and got flattened lists for both examples that you pasted. Maybe the answer to this could lie in the documentation provided in the source of SOAPpy: simpleTypes.txt & complexTypes.txt There are a few examples in there that show how to serve/retrieve actual data structures. I don't know all the details but SOAPpy is an incomplete library from what I've read. It works for me though (for now anyway) b/c I only use simple single dimensioned arrays.

Using windows authentication IMHO should only be used if there is an Active Directory/LDAP server set up against which the users are authenticated. I googled for 'active directory python' and came across http://tgolden.sc.sabren.com/python/ad_cookbook.html It seems to be very simple to use. If I were to implement an authentication system like you want. I would: 1. Check to see if the local machine was part of a domain. If not then inform the user that they need to be. 2. Check to see if the user who ran the application is part of a specific group in AD. I would assign each group a certain 'level' of privilege and accordingly let the user do what they should be able to do. I hope this is a good starting point. - Jonathan Curran -- http://mail.python.org/mailman/listinfo/python-list

Paul, I mentioned Chapter 8 so that the HTML processing section would be taken
a look at. What Vertigo wants can be done with relative ease with SGMLlib.
Anyway, if you (Vertigo) want to use regular expressions to do this, you can
try and use some regular expression testing programs. I'm not quite sure of
the name but there is one that comes with KDE.

It can't be done with just Python & PIL, that much is for sure. First of all you need some sort of module/program/(whatever you want to call it) that can render a given webpage. Then you would proceed to capturing the graphical output of that module/program/... Maybe what you should look into are graphical toolkits that possibly provide a HTML widget from which you can get a graphical display.

Hynek,
It is possible to redirect stderr to a file so that in case of a crash
or
fault the errors will be logged to a file. I think the following code would
do it.
import sys
log_file = open('errors.log', 'w')
sys.stderr = open('errors.log', 'w')
log_file.close()
Hope it helps.

Heh, I kinda messed up the code there. It should be:

log_file = open('errors.log', 'w')
sys.stderr = log_file
log_file.close()
As for the Ctrl-C, you can catch that when KeyboardInterrupt exception is
raised.

Re: xml.dom.minidom memory usage
Dan, The DOM (Document Object Model) is such that it loads all the elements of the XML document into memory before you can do anything with it. With your file containing millions of child nodes this will eat up as much memory as you have. A solution to this is to use the SAX method of parsing XML documents and working on it. SAX is such that it only reads the XML doc. a node (or a few nodes) at a time. Unfortunately, the use of DOM or SAX completely depends on what kind of processing you need to be done on the XML document. If it is editing a record at a time (from what I've gathered from your code) it would be wise to use SAX. I highly suggest looking into this method of processing. - Jonathan Curran -- http://mail.python.org/mailman/listinfo/python-list
Re: xml.dom.minidom memory usage
Dan, I jumped the gun and didn't read your entire post. I ended up skipping a lot of parts, especially where you say that you are creating a document (for some reason I thought you were reading it).

I'd still ask you to look into SAX though :) Especially when dealing with really large XML documents, whether it be reading or writing them. - Jonathan Curran -- http://mail.python.org/mailman/listinfo/python-list
Re: xml.dom.minidom memory usage
Dan, Take a look at http://www.xml.com/pub/a/2003/03/12/py-xml.html. It's a starting point to output XML data via use of SAX. Bruno also mentioned Genshi.

message processing/threads
I've been thinking about this for a bit and wanted some input as to the design of it. The problem is as such: I need a program running in the background to process messages (FIFO order) which I would send using soap/xmlrpc/pyro (haven't decided yet). According to my thinking I would need to make this a threaded application. One thread to process the messages and the other thread(s) would be used to listen for messages and insert it into the message queue. Is my thinking correct? Is there a better way to do such a thing?
