Vacuum your Firefox 3

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.
Having database store your browsing data has one drawback, you have to optimize the database from time to time to get rid of old, deleted data, re-index the columns etc.
Otherwise you keep all the junk data mixed in with your real data.
In SQLite is the statement to do this called VACUUM. So here’s how to vacuum your Firefox:

1. Download sqlite command line client for your platform. In Ubuntu, go to yout terminal and issue the following command:

sudo aptitude install sqlite3

2. Turn off your Firefox
3. Go to your profile folder
4. Issue the command:
* For Linux

for i in *.sqlite; do echo "VACUUM;" | sqlite3 $i ; done

* For Windows

for %i in (*.sqlite) do @echo VACUUM; | sqlite3 %i

Enjoy!

Songbird: glibc 2.8 detects invalid free() pointer

Sometimes I use Songbird to listen to my music files or internet radio. On some systems running Ubuntu 8.10 it does not run. The error is a known bug reported by some people.
The resolution is simple. Just remove libvisual-0.4-plugins.

sudo apt-get purge libvisual-0.4-plugins

Enjoy your music!

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)

sudo apt-get install python

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

cd
wget http://www.djangoproject.com/download/1.0.2/tarball/
tar xzvf Django-1.0.2-final.tar.gz

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/.

sudo mv Django-1.0.2-final/  /usr/local/lib/django-1.0.2/

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

cd /usr/local/lib/django-1.0.2/
sudo ln -s `pwd`/django /usr/lib/python2.5/site-packages/django
sudo ln -s `pwd`/django/bin/django-admin.py /usr/local/bin/

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

django-admin.py --version

You should see this:

1.0.2 final

6. Happy programming!
