Hey guys, let's say you have a factory and have a starting budget. You can buy different machines which will produce a product you can sell to gain money. There's low tier machines with low profit and higher tier with higher profit, if a low-tier machine costs x and produces y a higher tier costing 2x will produce strictly more than 2y. You can buy new machines anytime. Is the best pattern always (if anytime) buying the lowest tier and keeping one until you can buy the highest tier? If not, how do you determine what should you do, assuming they'll never break and economy is just "object x= y money"?
>inb4 homework, I'd have given you more data to give me directly the answer
It's something more game-related, but it could also be seen as cryptocurrency-related (what gpu mining rig should I buy?). Just curious tho.

What's the best tool to manage information? I use Mindmanager but I don't feel very happy with it.

onenote is not visual enough, but thanks!

I use pen and paper. Sometimes i draw a crude, fast mindmap if in the process of understanding a subject well enough. My final mindmap should be spaced as evenly as possible. (This means I chose the right abstractions about the topic). By the time I am done, 95% of the learning is already done. I might review the mindmap some times, but usually I never look at it again, and also never forget the core concepts again.

Does entropy and heat make long term human space travel effectively impossible? How do you cool off enough when there's nothing but vacuum around and you can't afford to jettison anything? This is assuming there is enough energy somehow for continuous life support.

The only answer I imagined was extruding a fuckhuge thin surface material that cycles water through it edge it towards the background radiation temperature, but I have no idea if that would even work. Sounds problematic anyway.

convert to electricity and shoot it away with lasers?
>>
>>9161959
No. We call what you described radiators. Both the space station and the shuttle have them.
>>9161991
That is thermodynamically impossible

What's the point of human space travel? We hold ourselves so far back by trying to make traveling through space possible for humans. Humans just aren't made to fly a ship through space. It's like making an aircraft carrier to transport a Macintosh 1. Other stars are so far away that a single human could never hope to travel to them in a lifetime, and then if we do manage to colonize a planet far away, they would be an entirely different world because of the time communications would take. All this is so much easier to accomplish with robots and ai made specifically to mine the asteroid belt, or explore the distant planets of Alpha Centauri. Why go on with people?

Because answers are outer.

>>9161939
Because a human could do everything the rovers have done on Mars in a day.

Robots are fine for exploration but they are much slower than humans, simply because of the transmission latency. You could always try better AIs to work alone and just send data back and get overall instructions, but there's always other trade offs, like if an instrument jams there's nothing you can do from Earth, but a human might be able to diagnose and fix it.

And I don't think anyone is really planning any human trips to Alpha Centauri, just so you know.

What's the point of human space travel?
Because what the fuck else is there to do? stay on Earth until we wipe ourselves out? May as well make some token attempt to get off the planet.

Someone could explain how banking information during payment works especially during card-payment?

I mean all goes through a simple network/telephone cable , is there any encryption? any protocol ?Any safety features to. protect our data?

How this system could works in 2017 in this a really basic and simple way.

Any idea? any explanation to this?

If you have a leak in a hose you can see where it is

RSA or its variant

RSA ok thanks I will search it and figure it out how it works :D

by the way you can see a leak only if you where to look ;)

Wouldn't it make more sense for RR and RL to switch places? I don't understand why the naming convention for itineraries is like this.

I'm assuming it makes things easier somewhere.

did you make a post about some dude's naming conventions? This is actual autism
>>
>>9161409

Math is codified autism. I just don't understand why someone would choose such a (seemingly) convoluted naming convention.

Perhaps there's some hidden insight that I'm not seeing?
>>
Guise, can someone that's done some work with dynamical systems please answer my question?

My autism needs to be sated and it's getting pretty late here.

What's one way to solve any problem whether it be the Riemann zeta function, to interpersonal problems in society, to the anxiousness about a lack of meaning?

Killing yourself. The act of killing one's self is the same as having a cake and eating it too. Everything is fixed. The problems are solved, because if you're dead, the problems couldn't have existed in the first place.

There's absolutely no reason not to take some aspirin and slit your wrists vertically in the hot shower right now.

1) Not science.
2) Objective reality is unchanged by your perception of it, which is why it is considered objective.
3) Do it, pussy.

So then why haven't you done it?
That's right, because there are reasons to live.
You're just too much of an edgelord to admit it.

You sail 825m south.
Then you turn and head 60 degrees West of North for 1250m...

how many meters are you from the island that you first set sail from?

maybe what i'm actually asking is how many degrees west of north would the angle have to be that you are turning for the hypotenuse to become different than the 1250m line
>>
>>9161184
less than 1497m

>>9161184
856m

Why is there so much bias in the scientific community towards women?

Ugly women make the best physicists because they're too ugly to be whores and males are always looking for something to stick their dick in, regardless of social standing, so they can get distracted.

Ugly women are the next best thing to androids when it comes to science.
