39. is presented by members of the
United Kingdom’s Ubuntu Linux community.
We aim is to provide current, topical information about, and
for, Ubuntu Linux users the world over. We cover all aspects
of Ubuntu Linux and Free Software, and appeal to everyone
from the newest user to the oldest coder, from the
command line to the latest GUI.
Because the show is produced by the Ubuntu UK
community, the podcast is covered by the Ubuntu Code of
Conduct and is therefore suitable for all ages.
