Secure delete with python

[Michael George Lerner]

Seriously? What OSen are known for [writing new content at
another location of the disk]? I'd had thought that if
the file size is unchanged, the data is always written over the old
data...

It can even be filesystem specific. Back in the days
of WORM drives (do people still use those?)

I know that some government agencies were still using them as recently
as a couple of years ago .. there were some regulations that said that
you had to keep undeletable backups of everything. I think your choice
was basically between a warehouse full of file cabinets and a WORM
drive or two.

....or much-cheaper CD-R (not -RW) disks...? Not sure about how well
they'll age, but they're write-once, read-many, too, and cheap (besides,
they don't cost much...;-).
