you will spend much MUCH more time as a power law user than as a new user, such that almost any % gain in productivity once familiar is worth almost any months of unproductivity when new.

"Make a line of 10 apples and declare it to be 2 units long" <- what number does this physically realize?

> Why would countries have funds to help places like Haiti otherwise?

because that's what they think is best. what point are you trying to make? that countries don't pursue 'profit' at the expense of all other concerns?

in what way does drawing a diagram have anything to do with physically realizing a number?

> equality is undecidable

equality is always undecidable until you see the light of intuition. consider the rational number whose numerator is 0 if $theorem is true, and 1 if it is false, and whose denominator is 1.

"suppose that the minimum distance is one inch. well, that's one of something. so now imagine half of that! there you go: one half. a physically unrealizable number."

the correct answer here is that they are all accountable. there is not some fixed quantity of blame to divvy up: each malfunctioning leg is responsible for the outcome.

testaccount28··on New study compares growing corn for energy to solar production
right. view it instead as "we need to keep domestic corn production above a certain threshold." the result is that we have a lot of extra corn. now the question becomes: what do we do with this extra corn? we can either throw it away, or turn it into fuel.

it's not an efficient course if the target is fuel, but that's not the target. it is a decent use if we have lots of corn that nobody wants, which we do.

derivation of -x seems wrong. we can look at the execution trace on a stack machine, but it's actually not hard to see. starting from the last node before the output, we see that the tree has the form

    eml(z, eml(x, 1))
      = e^z - ln(eml(x, 1))
      = e^z - ln(e^x)
      = e^z - x
and the claim is that, after it's expanded, z will be such that this whole thing is equal to -x. but with some algebra, this is happening only if

    e^z = 0,
and there is no complex number z that satisfies this equation. indeed if we laboriously expand the given formula for z (the left branch of the tree), we see that it goes through ln(0), and compound expressions.

x^-1 has the same problem.

both formulae work ...sort of... if we allow ln(0) = Infinity and some other moxie, such as x / Infinity = 0 for all finite x.

testaccount28··on AI Will Be Met with Violence, and Nothing Good Will Come of It
right, i love this plan, we are aligned politically. but until we make some change to the balance between renters and landlords, subsidizing demand is unlikely to help.

or just pay the landlords directly and cut out the middlemen!
