Mount option hazardous to USB Flash!

[Thomas Zehetbauer]

I wonder how Windows(tm) is handling this. I guess it starts writing
pretty soon but maybe it delays writing the FATs.

AFAIK SD Cards use dynamic remapping to prevent this type of wear out,
but even in this case the sync option shortens media life and should be
disabled.

Governments, if they endure, always tend increasingly toward aristocratic
forms. No government in history has been known to evade this pattern. And as
the aristocracy develops, government tends more and more to act exclusively
in the interest of the ruling class - whether that class hereditary royalty,
oligarchs of financial empires, or entrenched bureaucracy.
