Well, a couple of points: its not obvious that Chinese doesn't have a context-free grammar: see the talk by David Branner: "The Grammar of Classical Chinese is Very Close to Being a Context-Free Grammar". And a properly pr

A turing machine is defined as a set of symbols which it can read/write to the tape, and a state machine which maps the current symbol read to the next state and some actions. The symbols of the Turing machine are atomic . They are n

Yeah, but timestamp is only one of the keys you might like to sort on. To sort on anything else you'd have to augment the UUID anyways....why is a timestamp so important that it is put in every UUID, whether the user needs it or not?
575.
by rhelz 3y ago
A question: why include a timestamp? Why not just 80 or 128 bits of pure randomness---if somebody needed a timestamp they could always just append it themselves. And, it seems to me, there would be many instances where you didn't n

re #1: the conflation is justified, but you couldn't guess that just from what was presented in the OP. There are some cool theorems which justify it tho---if you like Kolmogorov complexity you are in for a fun ride. re #2: No. Bas

There is another, more insidious, problem with trying to give a language agnostic definition: Different languages will have different symbols which are outputable. If you have a Turing machine which can only print out binary digits, then i

I think its bootless to try to define the "minimum possible" Kolmogorov complexity. Here's why: 1. Note, kolmogorov complexity is defined by the length of the shortest program which prints out the string. What counts

no, even if you are a greedy kapitalist pig, we'd be better off not burning the carbon...because: 1. You can't scrub the air using energy from burning fossils fuels--it puts more C02 into the atmosphere than it yields energy to t

> consider the alternative, not doing it....Let the temperature rise so fast... Sounds like the obvious choice...but can you put some numbers to it? 1. How much C02 do we need to take out of the air to prevent your doomsday scenario, 2.

> Just stopping burning carbon isn’t enough. We need to take the existing excess carbon from the atmosphere. Yeah, I just don't see that happening. E.g. suppose we only wanted to take the CO2 out of the air that we put in last year

by rhelz 3y ago
After a plane burns all its jet fuel to fly where it is going, we will have to expend even more than that much energy to suck the C02 out of the air again. Flying will cost at least 2x as much as it does today.

by rhelz 3y ago
We have the tech today. Its just 1) too expensive, and 2) thermodynamics says it always will take more energy to suck the C02 out than we got from putting it there, so what's the point?
584.
by rhelz 3y ago
But....I mean, for that 5-10%, we have to spend MORE THAN DOUBLE the energy we get from burning carbon....wouldn't we just be better of not burning the carbon? It doesn't compute. I mean, you get my point, right? That 5-10%, su

I really don't see the point of this...it takes at least as much energy to "unburn" the CO2 in the air back into organic molecules, as burning the coal/oil released in the first place. (If it took less, we could make a p
