How do you check if your webcam is working properly?

The thread I link to has some common ideas, mostly involving installing applications which use the camera. You don't have to go that far.

The easiest way to check that it's working properly without installing anything is to run gstreamer-properties from ALT-F2 or the terminal. On the "Video" tab, look for the "Default Input" section and click "test." You should see the webcam's video output.

Also, now that Cheese is installed by default on Hardy, you can use that application. If it goes away in Hardy+1, though, you can still use GStreamer.

Drupal: Readable path

This toturial will show you how to replace the default path of drupal by custom path.
Example:

www.mysite.com/?q=node/add/article => www.mysite.com/?q=create-article
www.mysite.com/?q=node/1 => www.mysite.com/?q=hello-world

Using Path module, you can:

• Set the path for individual node with the Path module (on the node/add or node edit form).
• Add a URL alias at 'Administer > Configuration > Search and metadata > URL aliases'  in Drupal 7, 'Administer > Site buiding > URL aliases' in Drupal 6.
