Someone mentioned how hard it was to write "memory safe" apps for
embedded
devices, considering how the stack is dynamically allocated. I pointed
out
that this isn't that hard.

Having enough RAM is fine for a pc. An embedded device running linux
will likely
be mass-produced with the minimum amount of RAM though.
