This algorithm does not contain a value judgment

multiples = []
for i in xrange(2, n+1):
if i not in multiples:
print i
for j in xrange(i*i, n+1, i):
multiples.append(j)

to think the particular as

You don't see it, but medical imaging technolgy heavily
relies on value jugements. The bad thing: most of it
comes as a black box.

The classification algorithm you chose effects your
results. There is no true of false. Just the costs of
missclassification.

We have to make a decision for:
- the method
- which algorithm?
- boundary conditions
- which parameters?
- dealing with errors
- which risk funktion?

Technology like our
smartphones are like a

Developers:
• keep as many options open as possible
• give others a chance in changing the pre-sets
Educational systems:
• teach people to hack, to become curious about

Legislative bodies:
• make hacking things legal. Only what gets
hacked, gets tested.

the things we have to deal with,
let us shape our surroundings
according to our ethics.
