New helper script: SVN updater using Growl notifications

daniel — Wed, 27 May 2009 10:16:27 +0000

This small helper script should be added to cron and checks your local working copies against the online repository. It can automatically update your working copies if a newer revision is available. The user will be informed using Growl popups. As Growl is only available for Mac users it’s a Mac only tool by now.

The script currently registers with Growl using the classes from Python bindings. This is not necessary and would also be done by growlnotify. I was just interested in how this whole Growl stuff works. Feel free to remove this parts.

When i started i was willing to do the whole Growl stuff manually which has worked very well from the command line but not from cron. Seems like the context or something else get’s lost and no notifications pop up anymore. To be able to run via cron i switched to growlnotify.

New Project: Django-powered Nagios configuration

daniel — Thu, 05 Mar 2009 14:11:32 +0000

It’s time for a new private project: The Django-powered Nagios configuration.

The idea resulted in reading the book “Python Web Development with Django”. One of the authors describes one of his projects for internal use: a Nagios config manager and i think it’s a great idea. I just played around with the idea but it got pretty usable so far. It’s not in a production ready state but as soon as it may be usable to you i will release it. Here’s a development screenshot:

daniel — Tue, 10 Feb 2009 20:44:58 +0000

I recently started to work on a new Django project and tried use my default IDE: Komodo IDE. Unfortunately it didn’t work out the way i wanted. Code cpmpletion didn’t work just as the import of my app. Here’s how i solved it:

Add a new Python import directory: Preferences -> Languages -> Python

My Django resides in /Library/Python/2.5/site-packages. Your installation may be in a different location.
Create a Komodo project for your new Django project and edit it’s properties: Properties -> Languages -> Python My project resides in /Users/dkerwin/development/django/stag_party with several application inside.

Installing iPython under MacOS X

If you don’t know iPython by now: check it out

It’s a pretty nice tool if you work with python from the terminal. Especially the easy way to get information about modules and functions. The easiest way to install (especially in a Mac environment) is to use the “alldeps” tarball.

deathstar-mac ~ $ wget http://ipython.scipy.org/dist/alldeps/ipython-alldeps-0.9.1.tar
deathstar-mac ~ $ tar xvf ipython-alldeps-0.9.1.tar
deathstar-mac ~ $ cd ipython-alldeps-0.9.1.tar
deathstar-mac ~ $ make

The default install location is ~/usr/local. You may change this by modifying the install scripts but for now use the default. Now it’s time to make some modifications to your profile. Add the following lines:

deathstar-mac ~ $ export PATH="$PATH:/Users/YOUR_USERNAME/usr/local/bin"
deathstar-mac ~ $ export PYTHONPATH=$PYTHONPATH:/Users/YOUR_USERNAME/usr/local/lib/python2.5/site-packages

Let’s complete the installation process:

deathstar-mac ~ $ iptest
deathstar-mac ~ $ cd ipython-alldeps-0.9.1/ipython-0.9.1
deathstar-mac ~ $ python setup.py install --prefix=~/usr/local
 
deathstar-mac ~ $ ipython
