/sci/, how can I help bring forth the singularity?

Plan is to become an AGI researcher; almost done with my master's (compsci) but not sure how to find a fitting phd position - there is at best tangentially generic "machine learning" shit available, and I don't have any special qualifications to expect to be accepted anywhere else over the expected hordes of I-want-to-suck-deep-learnings-cock-cucks.

I am a German citizen only if that changes anything.

Is there any other way to become a (reasonably paid) AGI reasearcher than aquire phd, gobble google dick? Additional constraint would be that it should work as fast as possible (emphasis on the last word).

No, working for google deepmind is the best thing you could do.

Sure, you could try Ben goertzel "hey guys lets open source AGI xD" or the many other even less respectable initiatives in AGI.
>>
>>8066581
And how praytell am I getting accepted there with just a master's in compsci? It's not like everyone wants to work there...

Hello /sci/. Greetings from /tg/!

I am currently working on a science fiction setting, and for several reasons I would like to know if it's possible for stars to be any weird colors. For example, I looked up that potassium chloride burns purple. Would it be possible for a star to achieve fusion with a large amount of potassium chloride it's make up?

Alternatively, if that would be completely fucking retarded and I should kill myself, before I grab a rope is there a scientifically possible way to explain stars being vastly different colors than usual?

The color of the light depends mainly on the mass and at what part of his lifespan the star has reached.

The "peer review" meme is damaging the scientific progress:

>Peer review switches from merely useless to actively harmful. It may be ineffective at keeping papers with analytic or methodological flaws from being published, but it can be deadly effective at suppressing criticism of a dominant research paradigm.

What if we limit criticism to technical details and let theories compete freely?

Why do experiencing something as "good" feels good?

I'm not talking about oxytocine or the likes of it. I want to understand why the release of certain molecules is associated with a good feeling?
What's the fundamental difference between pleasure and pain? Pain and pleasure are often evolutionary advantageous, but this is not the topic.

Any insight?
I'm not sure I have been very clear, it's hard to express. Feel free to ask for more details.

Generalized
Certain chemicals will fit into receptor sites that are not necessarily intended for them. For example, a pleasure inducing chemical may be able to fit into the dopamine receptor site. So, where do these pseudo chemicals come from? Caffeine, for example, originated in a plant as a sort of defense mechanism intended to ward off or kill predators. Sorry I can't be any more descriptive than this because I don't really know.
>>
>>8066403
Sorry as I thought I didn't convey my thoughts very clearly.

I know some chemical processes give you a feeling of pleasure or well-being.

But what does it mean to feel pleasure or to feel good? What is pleasure in essence? Is it related to consciousness?
>>
>>8066389
>Why do experiencing something as "good" feels good?
Feeling good is the definition of experiencing something as good.
>I want to understand why the release of certain molecules is associated with a good feeling?
Brain signals are associated with all feelings, and no feelings aren't associated with brain signals. Why would good feelings not be associated with certain signals?
>What's the fundamental difference between pleasure and pain?
Not much really, it's also worth noting that there's no real difference between the various senses and pleasure and pain. I mean just try and rigorously describe the qualitative differences between the experience of touch and hearing, or pleasure and sight. They're all just signals you're interpreting. Values stored in a neural register somewhere in your cranium

So it's coming towards the end of semester and I wanted to buy something for my maths and physics teacher as a little thank you. Budget is around $30. Can anything think of a suitable gift?

I have 2 matrix from 2 different grayscaled Imagedata.
i merged in a single matrix qq and now i must apply a formula that was sent to me today as ColorFunction.


ColorFunction -> (RGBColor[1 - 1/3 #[Alpha], 1 - #[Alpha], 1 - #[Alpha]] /. [Alpha] -> 0.9 &)


i never used this option and when i try using it i get only errors, i tried with

ColorConvert[Image[qq],ColorFunction -> (RGBColor[1 - 1/3 #[Alpha], 1 - #[Alpha], 1 - #[Alpha]] /. [Alpha] -> 0.9 &)]

i am just a novice in mathematica
how should i solve this problem?

Try
ColorConvert[Image[qq], ColorFunction -> (RGBColor[1 - 1/3 # 0.9, 1 - # 0.9, 1 - # 0.9])&]
>>
>>8066274
ColorConvert::imgcstype: ColorFunction->RGBColor[1-Power[<<2>>] #1 0.9,1-#1 0.9,1-#1 0.9]& is an invalid color space specification.

nope just errors
>>
>>8066284
Well then there's something wrong with the output the color function is producing.

Do you know what it's supposed to do? Do you have examples?

Here's my version.
When (and if) we hit post singularity and become immortal gods that can bend reality to our whim, how many of you would fuck with the universe for fun?
I know I would.
So here's my question, if there was an alien out there that reached that point, why don't we find more stupid shit floating around space?
Why isn't there a star sized alien version of the bird screaming obscenities in the center of the galaxy?

Well you see anon, there is a trend in communication technologies where the operational frequency is increasing. Higher operating frequency = more bandwidth. First we used radiowaves, then we used microwaves, and now we use visible light (in the form of fiberoptics).

The logical end point of this trend is communication using modulated gamma rays. Gamma ray bursts may in fact be ayy lmaos giving us the bird.

Once computers advance to a point that they can perfectly simulate anything anyone might want, there will be no reason to explore space.

Why spend time and resources going somewhere else and taking even a tiny amount of risk, when it's possible to do the exact same thing with no risk and identical results?

Need a math geek to help me out with a probability question:

You have a range of 20 cards each consisting of a number and a letter, labeled as follows:

1a 1b
2a 2b
3a 3b
4a 4b
5a 5b
6a 6b
7a 7b
8a 8b
9a 9b
10a 10b

One at a time, you draw a number/letter card. You can't draw any of the above cards twice and you do not return the card to the deck.

What formula would you apply to figure out the average amount of unique numbers drawn after x draws. (ie: after x draws, on average you would have Y% of unique numbers.)

On the first draw, you have a 20/20 chance of drawing a unique number.
On the second draw, you have an 18/19 chance of drawing a unique number.
etc etc

Wouldn't it always be 100% because you don't return the card to the deck?
>>
>>8066146
Rather, 1a / 2a are both unique numbers, 1a / 1b are not unique numbers.

Just because a company calls it's code monkey jobs SE doesn't mean it's actually SE, you can't legally give an SE job to anyone without an accreditted SE degree.

The reverse

The level of activity in the brain of neurotransmitters such as dopamine and norepinephrine may be the reason for this.[100] Such chemicals will either excite or inhibit the firing of neurons in the brain, with a greater firing rate allowing the brain to register the occurrence of more events within a given interval (speed up time) and a decreased firing rate reducing the brain's capacity to distinguish events occurring within a given interval (slow down time).
