im looking to graph distribution of a token on btc chain.
The block reward (combbase) at Bitcoin height h, in COMB unit, is defined to be:

MAX(2.1-FLOOR((LOG(h)/LOG(2))^6)/100000000, 0)
total theoretical maximum of COMB is 12423823.18141419
h is block number we can start at 604392 current block.

Aids can be mostly controlled by drugs at this point. Tell me you would prefer aids/cancer to being trapped with this brain for 50 years (dying at 50 because the cortisol from the constant stress destroys your heart).

Evolution doesn't always have (or need) a reason. Example: T-rex. Largest and meanest predator the world has ever seen.
12 meters long
3 meters high
8+ ,metric TONS of sheer killing power
This thing was fucking death on 2 legs.

What did it in? A rock. A fucking rock bitch slapped the whole damned species. Starved them all in months. What survived? The smallest of the underground burrowing mice-like animals.

Evolution is not about being the best, or the smartest, or the strongest. It's about being the fittest to the environment. If the environment gives x a reproductive advantage, now or in the future, then x will survive.

goddamn I hate computer scientists. You think you can do everything with just an image sensor? Well IRL it's really fucking hard to manipulate shit with just image data.

They way I cram: open the material the that you need to remember/learn. Open the page where all the contents are listed (if it's not textbook, then write a list of what you need to learn/remember yourself. Then just (1) read each entry and try to remember everything you know from it chapter. Then when (2) go to the one you remember the least and (3) skim through it so you get a basic understanding of it. Repeat step 3 with every chapter then go back to step 1 and keep filling in any blank spots in your knowledge. In my experience if your knowledge of something is lacking then getting a general idea of all of it is better than going through the material start to finish, because you can usually fill in the blanks through logic(depending on the subject, of course). Breaks are optional(I personally don't take breaks because if I interrupt the flow of learning I usually get lazy, but if you're feeling mentall fatigue then take a quick break, no longer than 5-10 minutes. And when I say break I mean going out to breath some fresh air or atleast opening the window and doing a quick exercise). Also, caffeine is your friend

Peer review without journals
In the age of information in which we live have journals become outdated in their ability to be objective and disseminate research to peers to review.
It seems prudent to have the ability to filter misguided or cluttered information. But is that really the role in which should be entrusted to an editorial staff?
With the dawn of artificial intelligence at hand,it seems prudent to develop a standard of rules for Publications in a decentralized manner. And having an AI as the publisher that can be used for basic correction of typos and formula.
It seems prudent to get away from human error when it comes to what new ideas the science literate are allowed to consider as part of the scientific community.
In conjunction with this it seems also prudent to differentiate between mathematical propositions dealing with interpretations and hard experimental data.
Too often it seems in order to get the basic two-page report on petabytes of information you have to pay upwards of $40 or more. I understand there are those who wish to make a full-time career from their theoretical and experimental research, but it seems but this method of pay first to see results any system that promotes desk-bound scientist that do no experimentation as they attempt to maximize profit by minimizing their expense and for going experimentation in many papers.
The social science of the scientific community cannot be held to some other standard as if those that claim the moniker of scientists are completely altruistic.
For science to advance: data must be free.

1: Male brain sees females,
2: Male sexual desire associates these females with pleasure,
3: Male brain fails to become imprinted by male role models - the man never gets excited about acting like someone who looks male,
4: The male brain looks desperately for an identity,
5: Literally his only social interaction is his mother,
6: Subsequently, he can only imagine a female social role which implicitly goes along with looking like a woman,
7: The man begins to judge himself by the standards of his grasped-at female social role, and he judges his body to be manish and unattractive.

It's caused by neglectful and/or emotionally abusive fathers who never make it seem cool to be a man.

The conditioning is so potent that the transsexual, much like the duck raised with the ball, can never learn to see men as 'cool.'

>it's basically a bunch of straight dudes who can't deal with the fact that they enjoy assplay as a man
>they can't see the light of "i can be submissive" without fully thinking "i want to be feminine, i want to be a woman"

1: Organisms learn their social role and the brain rewards them for fulfilling it. Conditioning is programmed, and hijacks the directionless reward pathways. 90% of manhood is cultural, including the notion that men shouldn't submit during sex. Men want to be like the men around them.
2: I'm sexually aroused by the thought of gayness, because it subverts the expectations of heterosexual cis-gendered identity - it is 'perverted.' The novel is arousing, and novelty related to sexuality is perverted
3: The sexuality is just a facade because the man's female goal body is sexually attractive to his intact male sex drive - he perceives this sexual arousal to be out of character for his female identity and projects his sexual thoughts out of his mind onto other people, who feminize him against his will, thus eliminating his culpability and preserving his shallow male identity for day-to-day interactions.

Speaking as a straight guy with a wife who used to watch a lot of tranny porn, I reason that I enjoy that porn for two primary reasons:
1.) I enjoy seeing men weaker than myself being dominated.

Depends if you'll actually go through the material and then take notes and then review that. Reading the powerpoint at home has the risk of giving you a false sense of confidence.

I'm 100% on the side of lectures are outdated and dumb. Almost all of the classes that had lectures manipulated the class somehow into attending either by making attendance part of the grade, making the lecture slides not available online, or having vague slides/a mix of actual notes and the slides. For the most part lectures are a waste of time if you can get the slides at home, but for some they learn better through it.
