In praise of floppies
Behold the floppy, a miracle of post-modern technology! Does your computer still have a floppy drive? Count yourself among the lucky!
Why? Thousands of reasons!
Do you have an ultralight lifestyle? Are you a maximalist? Are your computing needs sufficiently sparse to fit your entire home directory into less than a megabyte and a half?
If so, then you too can use floppies to back up your personal files! And if you are daring, you could even run your entire system with a floppy as the home directory. Yank that floppy out, and bingo! your precious data are safe and secure!
