Read some of Alexander Lowen's books, he talks about how posture can actually be an indication of something going on emotionally in the person. When people clench their jaw they're said to be grinding through life.
Ok but that can still be true (blonde hair, blue eyes) while there still being much more variations in the white population than in the black population.
I'm curious how many white people there are on earth vs how many black people there are, and other races. A couple google searches didn't give me any easy finds
Black people can have blond hair and blue eyes also. Common in Melanesians but not unheard of in African Americans either. I had blonde hair when I was a baby and genetically I'm 83% African (average admixture across all Black Americans). An uncle of mine had blue eyes when he was born
That’s because “white” and “black” are loose, shifting, ideological constructions with little basis in the scientific reality of human genetic variation. Many “white people” weren’t considered “white” until fairly recently and Africa actually has more human genetic variation than anywhere else.
I always cringe when reading about "race" in the US, the term really (intentionally? ) gives the impression that there is a clear genetic demarcation between people based on skin color.
The US is the only country I am aware of who still uses this term, everywhere else was using some thinking like ethnicity to indicate different culture, origin...
The UN pushed from the 1950 to replace race with culture. Many people around the world now say "But he is from a different culture." Instead of "But he is from a different race."
> little basis in the scientific reality of human genetic variation
This meme dates back to a loose claim made by R. Lewontin back in the 70s. In fact, you can very precisely and reliably recreate the "intuitive" human racial categorization using unsupervised algorithms, like doing multi-dimensional clustering over fixation indices. (It does not work using single-dimensional clustering, which is what Lewontin was talking about.)
Modern biologists usually talk in terms of clines rather than races, but this is just using the first derivative instead of the zeroth - you'll get the same result either way.
> Africa actually has more human genetic variation than anywhere else.
SNP diversity has ~nothing to do with phenotypic variance.
Of course the question here is recreate whose “intuitive racial categorization” because all of that is historically and culturally specific. Saying it’s possible for a computer to recreate these categorizations presumes that the categorization has some objective reality outside of this when they’re just a variable heuristic determined by all those inputs.
> all of that is historically and culturally specific
Not really - almost everyone can agree on "middle eastern/north african", "east asian", "south asian", "black african", "white", etc. If you force people to pick a single-digit number of major categories, they're probably going to come up with the same categories that k-means in fixation space would.
This is an evidence-free supposition, consistent with your pattern across this thread of making broad claims without anything to support them. You’ve provided no proof that k-means on a representative sample of phenotypic variation in the groups you cite would return this result.
That almost everyone can agree on these categories is also contrary to reality. For example, many of who you describe as East Asians consider themselves racially distinct both within their societies and from their nearby neighbors. Also, what major categories do mixed race people fall inside?
It's not my job to provide detailed proof on every HN post I make; I'm just pointing out something relevant, and if it interests you, you can go ahead and find where people have already done this. I think I've been specific enough that you can find this stuff on your own. This took me about 1 minute to find: https://www.discovermagazine.com/health/to-classify-humanity...
> many of who you describe as East Asians consider themselves racially distinct
That's why I specifically mentioned the number of racial categories involved. Obviously as the number increases you can have different clustering results.
> Also, what major categories do mixed race people fall inside?
Obviously not into any of them, if we're talking about a simple mechanical classifier with high separation.
The number of racial categories would itself be an arbitrary limit not corresponding to actual genetic variance, nor would classification under such limit capture said variance, and none of it would match up to the folk biology of racial categorization. This is the general problem with reasoning backwards from 19th century gobbledygook about human genetic variation instead of beginning with the genetics themselves.
It may not be “your job” to provide such evidence, but you’ve made a series of specific claims about things like the rate of phenotypic variance among different racial groups. If you don’t want to defend them, that’s your prerogative, but you also can’t expect them to be received as authoritative or remain free of challenge.
> Ok but that can still be true (blonde hair, blue eyes) while there still being much more variations in the white population than in the black population.
Even the man who coined "Caucasian" as a racial category recognized that there was more physical variance among African populations and individuals than compared with Europeans.
It's a huge lie that once you've achieved the "american dream" (which I don't think is the real american dream anyways) then everything will be sorted out. yes your life will be more amazing, and it's 100% important to reach this place, but once you've hit that place you'll lose a lot of motivation and energy, cause now lack of money, lack of family, lack of anything, doesn't kick your ass during the day. so you have a huge new challenge on your hands, and that is to re-invent yourself and discover what can move you now. you're embarking on a set of veryyyy difficult questions around what's the purpose of all this, what's the point of this, what the heck should i do with my days now. just know that you've been put on this journey for a reason and there's a way out and listen to your heart more than anything else. trust yourself. and be patient. there are answers out there and they will make you more fulfilled than you can imagine. the worst thing you can do is turn a blind eye to what your heart is saying and dive back into work and whatnot. you're doing the right, difficult thing by sitting patiently and staring right into the eye of the storm, so despite it appearing you're doing nothing with your life now, you're going through a lot of inner changes that will ultimately lead to a lot of outer changes.
Many course use GitHub as a part of their submission process. NC State connects a Jenkins server for their automated feedback to students. This would assist by reducing the number of platforms students need to use while learning CS.
Not when you consider how oddly ubiquitous Office was in classrooms (though it may now be seeing competition from Google?). It’s a brilliant sales strategy. Get paid now for professional training of your software, then get paid again when the kid enters the workforce and expects their company to have the software.
My thoughts exactly. While they are busy embracing Linux, they should look into adopting its mindset of having one program (web-app?) do one thing well, and only one thing. It would be a shame if the base github.com got bloated.
There's one from NYC that says: "A police officer forcefully pulls off a protestors face mask and pepper sprays him. The protestor had his hands up in surrender when this happened."
If you look at the video though the guy was pushing towards the officer against the officer's hand. What do you expect to happen when you decide to aggress on an officer instead of back away?
I watched that video. You have clearly mastered the application of Newton's third law, by pointing out that when someone pushes you away with their hand, you are also pushing against their hand. We only disagree about whether it's correct to pepper spray someone in the face when this happens.
I agree. We clearly have a dramatic difference of opinion about when it is a good time to pepper spray someone. I suppose the police officer in the video shares your opinion, and the authors of the document share mine.
The cops seem to have a low threshold for using it.
There was a video where a bunch of riot police were riding on the outside of an SUV. One fell off of it to the ground, got back up turned around and pepper sprayed behind him, even though there was no one behind him. There was no one moving towards him or even near him.
Truly an insane moment that really underscores the level of fear these cops are acting under. If they are that unstable, they should not be out in the field currently.
I have said this elsewhere on HN, but I think these protests would be better for everyone if police simply did not show up. I think the video we are referencing is a great example why.
The national guard is backing up the police. The police presence there was long before they came in. So yes, like Minneapolis. If the initial police response was different we could see a vastly different landscape of protests currently, but that set the tone and virtually no departments have been effective or even been trying to deescalate it seems.
A complementary repo which would be interesting to make to give a more complete view of the situation is one listing the destructions, lootings and physical agression made by non-police forces.
I did a coding bootcamp in Austin TX at the age of 18, instead of going to college, and got a job right after at a startup making $40k USD/year, which became $50k USD/year in a few months after getting a raise, and then after working there for a year I switched jobs to a top tech company many of you know, and by 21 I was making $75k USD/year
I got a lot of socializing at both companies, got to hang out with guys my own age and guys older than me, got to have some fun (maybe not as much as my peers in university), got to grow up, etc.
I think university back in the day used to mean a lot more, and I would have enjoyed it, but now it's so watered down cause everyone goes, and political / cultural movements have made the university programs require much more effort and much less thought
Just my 2 cents
Edit: also, to add to this, at the same time I also learned a lot of stuff completely outside of the domain of software through books on my own. philosophy books, history books, sociology books, etc. etc. I really liked that I was able to carefully select the authors and books and topics to the ones that grabbed my eye.
edit 2: oh ya! i also got a lot of fun socializing at the bootcamp too.
