Fill up disk space (for testing)

For disk space constraint testing. Leaves a little space available for creating temp files, etc. Easily free up the used disk space again by deleting the dummy00 file. Can tailor the testing by building smaller 'blocks' to suit the needs of the testing.

WARNING: do not do this to the '/' (root) filesystem unless you know what you are doing... on some systems it could crash the OS.

last.fm rss parser

you can just use one awk script to parse the rss feed. No need to pipe so many awk's and sed's. Its ugly and inefficient.
