Finding RSS feeds

One you have a feed reader up and running, you'll want to subscribe to RSS feeds that support your favorite topics. You can search for them with Google, by using the "inurl" or "filetype" search modifiers. Example searches could include:

 inurl:rss security
 filetype:rss linux
 inurl:xml asterisk
 filetype:atom sphinx search

Note that there are multiple feed formats (rss, atom, xml, etc.) so it's recommended that you experiment with the search parameters.
