Core dump files NHF

Sensei writes “So you’ve installed the latest bleeding edge Linux distro, or have been trying out the latest beta release of KDE or Gnome. Now you’re discovering a multimegabyte file, called “core”, appearing in your home or root directory. Also known as a core dump file, they are usually produced when one uses software packages that are not quite out of the beta testing stage, e.g. bleeding edge desktop applications.”
