Last week I attended Linux Conference Australia that was this year hosted in Hobart Tasmania. The weeklong event has the first 2 days dedicated to mini conferences before the selected presentations over the following 3 days.
I was actually there by virtue of being a speaker and mini conference organiser for the Open Radio mini conference. If this may interest you, you can read about it over here on my Radio Blog. Unfortunately this meant a clash with the sysadmin miniconf, but there will be time to catch up on that.
