I was more thinking along the lines where people board SpaceX flights to Mars
and bring the lightest possible personal computers with them: raspberries
High radiation levels...
Or astronauts in earth orbit, or high altitude flights...
Moonbase

Sitting on Mars without a raspberry to play with ...imagine...
As to radiation, I moved house a month or so ago, been logging radiation for
years

  note the sudden increase,
  those are counts per minute from
   http://panteltje.com/panteltje/pic/gm_pic/

Why?
 Maybe the neighbors are building a bomb?
the extra radiation dropped a bit after I hovered the place a couple of times
but not much.



Of course ECC would be nice to have once the rad levels go way up when trump
presses the red button in despair.
Or maybe he will just ask for political asylum in Saudi Arabia...

zorry for drifting on the topic

Yes, rowhammer, not much is safe, long ago when hacking was less known I hacked
some sat pay-TV, did not take long.
Nothing is safe IMO.
You have to be just willing, motivated, dedicated, removed it from my site when
some politica started jumping on a chair
and screamed 'Hackers!!' like that woman in the cartoon does when she sees a
mouse, calls the cat, well you know who always wins
no not the cat.

This is very recent and nice:

I did read the paper last night and those guys have the dedication and
persistence, nice work!
