Deploying PyQt applications on Windows
July 12th, 2007 by exhuma.twn
My preferred way to deploy python applications on Windows is to use py2exe.
py2exe is a Python Distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation.
If you run in trouble with sip, read on…

OverkillFlickr: a Flickr API interface for PHP5
July 9th, 2007 by wickeddoc
I create a small Flickr API interface for PHP5 which takes advantage of the Overloading feature of PHP5.
Using the __call method we can dynamically create an interface to all the Flickr API functions using only a very small script.
The name of the class is purely ironic as it is a very simple and easy-to-use class and far from Overkill.

Writing Qt apps in python
July 2nd, 2007 by exhuma.twn
Writing Qt apps in Python with Qt3 worked. Somewhat. I never found the energy to get it all set up. Finally with Qt4 we have something that “just works”. At least on Ubuntu and Windows (haven’t tested anywhere else).
Yes, since version 4, trolltech finally decided to release Qt as well under the GPL. To most of you it’s all old news. But hey…. just felt like writing it down again 
The problems with SIP are finally gone. So you just install python, Qt4 and pyqt4 and off you go.

Using the ltree module in PostgreSQL
June 27th, 2007 by exhuma.twn
PostgreSQL offers the very interesting module ltree. It’s used to represent a tree structure within the database. One could represent a tree quite easily as a table which references itself. However, if you ever went along that road, you will know that it becomes very slow with larger trees. In addition, the SQL queries that reference themselves are very unhandy.
If you want to know more, what ltree can do for you, I suggest you go ahead and read the usage examples on the ltree homepage.
Installing ltree
This is the part that eluded me. On the homepage it only states:
cd contrib/ltree make make install make installcheck

Runnning a twisted application as windows service

Currently I am a bit busy, so I will just dump the post I found on usenet. Eventually I will clean it up…

Uh. *Maybe* that's the consensus, but it's not actually correct. You can have a tap or tac run as a NT service. Lets say you have a script "server.py" that is runnable with "twistd -y", you can do (and similar code will work for TAPs):
import sys, os
import win32serviceutil, win32service
class MyService(win32serviceutil.ServiceFramework):
"""NT Service."""
_svc_name_ = "MyService"
_svc_display_name_ = "MyService server"
def SvcDoRun(self):
import server
f = open(os.path.join(server.rootPath, "cyberhigh.log"), 'a')
from twisted.python.log import startLogging
from twisted.application.app import startApplication
from twisted.internet import reactor
startLogging(f)
startApplication(server.application, 0)
reactor.run()
def SvcStop(self):
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
from twisted.internet import reactor
reactor.stop()
if __name__ == '__main__':</pre>
win32serviceutil.HandleCommandLine(MyService)</pre>
import win32serviceutil, win32service
class MyService(win32serviceutil.ServiceFramework):
"""NT Service."""
_svc_name_ = "MyService"
_svc_display_name_ = "MyService server"
def SvcDoRun(self):

f = open(os.path.join(server.rootPath, "cyberhigh.log"), 'a')

from twisted.application.app import startApplication
from twisted.internet import reactor
startLogging(f)
startApplication(server.application, 0)
reactor.run()
def SvcStop(self):
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
from twisted.internet import reactor
reactor.stop()
if __name__ == '__main__':</pre>
win32serviceutil.HandleCommandLine(MyService)</pre>
