This tip will hopefully speed up your Firefox 3 by optimizing it’s database.
Firefox stores your browsing data using SQLite – self contained, small footprint database.

Install Django on Ubuntu 8.10

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
To install it on your Ubuntu, follow the next steps:

1. Install python (if you have it installed, skip this step)

2. Download the tarball from the Django Project website. You can download this file to your home directory.

3. Now we can just move this entire package to somewhere logical. You can move it anywhere you like, but remember to modify the links accordingly. I use /usr/local/lib/.

4. Link to it from the Python site-packages directory, and create a link to the django-admin.py executable.

5. Test it by changing to your home directory and running django-admin!

You should see this:

Set Drivel to Post to Your WordPress Blog

Drivel is a nice blog editor for Gnome. To install it on Ubuntu, run this in your terminal:
sudo apt-get install drivel
Now you need to configure Drivel to connect to your blog. Go to Applications -> Internet. Select Drivel Journal Editor.
When the dialog box appears, input your username and password into the first two textboxes. For Server Type, select Movable Type from the dropdown. Now the tricky part, for the server address you will need to enter the full path to the xmlrpc.php file on the server (for example http://www.yourdomain.com/yoursubdirectory/xmlrpc.php). Check the Remember password checkbox and the Automatically login checkboxes (if desired) and click the Log In button.

Happy posting!
