I remember reading that Kelly Johnson, of Skunkworks fame, created Systems Engineering as a bull-shit smoke screen to keep executives, bureaucrats, and bean counters off the backs of the actual engineers so they could do their work as usual. System engineering was created to make it look like everything was top down and preconceived, all t’s crossed and all i’s dotted, meanwhile the engineering’s proceeded as usual, and the Systems Engineering and Trade study results were penciled in afterwards.

I then remember the source going on to say it was a great tragedy to see this bull shit discipline of systems engineering being adopted by the aerospace industry in earnest. Instead of keeping bureaucrats out it added a layer of bureaucrats, instead of shielding engineering from executives it empowered them to turn an unrealistic wish list into hard requirements.

I thought I read that in Ben Riche’s book “Skunk Works.” But I’ve searched the e-book and can’t find it. I tried google but they are hiding the truth. Have you heard this story anywhere? I’ve been searching for the source and can’t find it anywhere.

> Von Neumann did some of his best work in noisy, chaotic environments, and once admonished his wife for preparing a quiet study for him to work in. He never used it, preferring the couple's living room with its television playing loudly.

> Despite being a notoriously bad driver, he enjoyed driving—frequently while reading a book—occasioning numerous arrests as well as accidents. When Cuthbert Hurd hired him as a consultant to IBM, Hurd often quietly paid the fines for his traffic tickets.

> Von Neumann entered government service primarily because he felt that, if freedom and civilization were to survive, it would have to be because the United States would triumph over totalitarianism from Nazism, Fascism and Soviet Communism. During a Senate committee hearing he described his political ideology as "violently anti-communist, and much more militaristic than the norm".

I haven't showered regularly in months.

I have a pungent odor now, that I would describe as similar to concentrated chlorine or severely rotten milk. (Something between the two, closer to a chemical type smell though.)
Portions of my skin are turning charcoal black and flaking/falling off. (I'm white/"cock asian")

If I continue to go without showering, could I potentially die? Like, is this a way people end up dead? I feel like I'm rotting alive. I am a depressed individual that wouldn't be particularly upset if my end is near, you get what I'm sayin'? So like, how long do I have to go without showering, before it's a threat to my life?

My IQ was tested and found at 130+, but if you would read how I write, you'd think I was the biggest retard around. Need another way
You go to his thread and say. Hi OP. So. Hi OP.
Intelligence below 145 (verbal prohibited) is irrelevant. The indications posted in this thread are only relevant around 120-135IQ. To find someone 145 or above (sometimes 140), you could look for an inquisitive personality, like someone who asks a lot of questions, even if they're subtle. I'd argue that you would need to look for people who are also arrogant, not narcissistic, there is a difference, who use "logic" as a way to bend people to their will. People below 145 often utilize social expectation and adherence to get what they want, logic isn't as much of a tool as it is for 145+. But with people who can calculate and strategize other individuals in their mind, logic is something that allows the more intelligent to tard wrangle the midwits in the 130s.

So, to recap: Be on the lookout for "logical", arrogant, inquisitive people. Before you start smug, braggadocios behavior is not the same behavior as arrogant you dumb cur.
If they are atheist/agnostic then they are guaranteed to be midwits, see: reddit.

Hypogonadism: Case Report

>A 42-year-old man presented with poor energy and low libido. He had mildly elevated serum prolactin with hypogonadotropic hypogonadism as evidenced by low serum testosterone with luteinizing hormone and follicle-stimulating hormone in the normal range. At his initial visit, he reported no use of any recreational or therapeutic drug. Two months later when seen in follow-up, both the testosterone and prolactin levels had returned to normal. At that visit he reported frequent use of kratom, which he had discontinued a few days after the first visit.

I am taking tea, coffee, and nicotine salts.
Anyone investigating nootropics before getting their alcohol consumption to zero, exercising regularly, and having a healthy diet is 300% full of shit.
Yes you can be 300% full of shit, it just means that you are 4 times your optimal weight, and 75% of that weight is shit.
I tried kratom a couple times, never really noticed any effect. Opioids don't do anything to me either, so maybe it's related somehow.

Nootropicswise, I've been taking Huperzine A immediately upon waking to counteract the morning narcolepsy I experience from my sleeping pills (hydroxyzine). It seems to be somewhat effective, my usual two cups of coffee isn't enough and ephedrine pills (Bronkaid) are less effective despite having a greater stimulant effect.
Kraton is highly addictive and I encourage you not to use it if you are at all prone to addiction. This bullshit repeated on reddit about it being like coffee is ridiculous. After a couple months of use you will feel like a zombie and the positive effects will drop to zero regardless of how much of that disgusting shit you take. The acute withdrawals are nightmarish; over a week of rls that will make you want to crawl up the walls at night. You become delusional from lack of sleep and intense anhedonia. After the acutes pass the depression and feeling worthless can last months. You have been warned.
Eggplant contains acetylcholine. I get anxiety from coffee. Eggplant good.

I have not found evidence for this beyond a single case report.[0] Kratom use was self reported and unmeasured. Opiates in general regulate prolactin.[1]

Agreed, the health trifecta of sleep, diet and exercise accounts for 90% of mental performance, and deficits in any of these will significantly impair mental performance. That being said most people can solve the trifecta for themselves so a nootropics thread is still useful.

If you are insensitive to opiates you will be insensitive to kratom. I'm sensitive to both, and enjoy them both. Kratom is much better for me because it's legal, cheap, and self regulating in that you are going to struggle to overdose or become addicted to the point of heroin/fentanyl style withdrawals.

Kratom should not be considered highly addictive. A typical highly addictive substance would be something like fentanyl or methamphetamine. I would say kratom is mildly to medium addictive for most people.

>the bullshit repeated on reddit

You can always go back. It sounds to me like you were taking too high of doses. I use the analogy of infrequent vaping to constant cigar smoking. Traditional use of kratom in Thailand and Malaysia is at a very low dose compared to how Americans use kratom. A typical traditional user will chew a single kratom leaf for a few seconds, long enough to taste the plant, then they will swallow once or twice and spit the leaf out. This is a fractional dose compared to the typical American dosage of mixing entire teaspoons or tablespoons of raw powder into a beverage, and drinking multiple of these throughout the day. My kratom use has been healthiest and most useful when I take the absolute minimum needed to feel the effects. I will drink maybe a quarter teaspoon twice a day. This is enough to take the edge off, and never enough to get high or feel lazy.

We all know the usual complaints about women being liars/cowards/retarded etc.
But wouldn't "fixing" women cause a bunch of other problems?
If you engineered women to be more intelligent/independent/physically fit (aka "masculine"), would the biological changes make them worse at motherhood? Intelligence and strong will isn't an asset when your main role is to do menial labor and the man is supposed to be the head of the household.

>your main role is to do menial labor and the man is supposed to be the head of the household.
women are the way they are in part because you consider someone who produces the food you eat and who keeps your house clean to be a "menial laborer" rather than giving them credit and thanks worthy of their tremendously beneficial activities.
instead you spend your time licking the balls of total strangers like black soience man. its a stupid value system.
>women are the way they are in part because you consider someone who produces the food you eat and who keeps your house clean to be a "menial laborer" rather than giving them credit and thanks worthy of their tremendously beneficial activities.
It is menial labor. It doesn't require a lot of skill or training. The man of the household doesn't do it because it's not worth his time when he can have someone else to do it.
The man is the one providing money for the household, while the wife is living rent-free.

This kind of environment doesn't select for go-getters and people with high aspirations.
