the disk of my vps is running out of space i had no idea what was the cause http://wiki.debian.org/FreeSpace gave me the hint to use ncdu. it was dead easy to find out a directory is using quite the half space i have in my vps. ncdu is great! thanks to Yoran Heling. by the way... the disk was filled by the podcatcher. i forgot podget which harvested some podcasts since 2010 ... i wrote about it http://debianisttoll.blogspot.com/2010/06/castget-podget-podcatcher-usable-with.html . podget is great.
