home_boi··on ‘Lopping,’ ‘Tips’ and the ‘Z-List’: Bias Lawsuit Explores Harvard’s Admissions
Look up the income statistics. There are very few low income students at Harvard and similar "holistic" universities. It's a school for rich people.

MIT cares more about scores and STEM and MIT actually has around the lowest family income and lowest percent of rich people in the Ivy League tier.

What "other goals" and "expectations"?

It conveniently falls in line with racial diversity goals but it is unclear what other goals it accomplishes. The reasonable assumption is that any soft skill goals or measures will have a high preference for white males. It is very suspect that this isn't true.

Don't admission officers actually come from worse educational backgrounds than alumni? I think many AO never reach educational or career heights that would help them appreciate the accomplishments of applicants while alumni do.

Those admissions processes are actually seen as very fair processes in those countries. IIRC, there is very high economic diversity in the top colleges in China and India which can't be said about the Ivy League schools.

Uniqueness and well-roundedness are traits of privilege. The activities typically used to signal "uniqueness" for college admissions like philanthropy and political activism have roots in privilege. If you're not from a rich, well-connected white family, the best chance for success is through the typical tryhard, academic STEM path. You can't afford to be unique. You don't have cronyism or money to fall back on.

That part sounds like a literal race quota.

I guess Harvard's defense is that they do most of the "work" at the subjective personality score stage where races are conveniently ranked in the same order as their desirability for "diversity".

home_boi··on ‘Lopping,’ ‘Tips’ and the ‘Z-List’: Bias Lawsuit Explores Harvard’s Admissions
It seems unlikely to be unintentional. Since Harvard is grading personality on a USA-centric scale, it would most likely accentuate the traits of the current USA leaders and executives who are overwhelmingly white. We would expect the white children to inherit, genetically and environmentally, these traits from their leader and executive parents and score the highest by a good margin and all other minorities to score low.

The results contradict the expectations. Conveniently, it is black > Hispanic > white > Asian which is exactly the diversity hierarchy

> Spacex: we can go to Mars, but haven't even launched a Mars rocket. Google: AI is here, and the product? Waymo, logs millions of miles, is just sunny conditions?

I don't think that is their literal message and goal. SpaceX's real mission is to innovate space travel which they've been capable of doing and have demonstrated with clear achievements.

SpaceX's revenue is in the billions and is very close to profitable. It most likely would be profitable if it wasn't constantly spending money to expand like Amazon in its early years.

Note that having children is something that only women choose.

Men and women choose to have sex. Women choose to abort or have a child.

home_boi··on High-quality schools can increase academic achievement among the poor (2010)
> A great school and teacher obviously can change the lives of children in poverty but it's astonishingly difficult and requires immense talent to achieve.

Teaching children in poverty is a specialization. Teachers can excel at teaching children at upper middle class schools but fail miserably at an inner city school. People complain about privilege on teacher quality difference between inner city and good schools. The truth is that the "good" teachers at an upper middle class school wouldn't be much of an improvement over the "bad" teachers at inner city schools. The "good" teachers only know how to teach well-behaved, studious students!

That is why integration failed. The environment at good schools are good for children with familial support and low behavioral issues. It is not good for children with behavioral issues without familial support.

home_boi··on High-quality schools can increase academic achievement among the poor (2010)
The most important methodology of the school:

> Like many charter schools in New York City, the Promise Academy has an extended school day and year, with coordinated after-school tutoring and additional classes on Saturdays for children who need remediation in mathematics and English Language Arts skills. Our rough estimate is that Promise Academy students that are behind grade level are in school for twice as many hours as a traditional public school student in New York City. Students who are at or above grade level still attend the equivalent of about fifty percent more school in a calendar year.

The students are working twice as hard as others and attend remediation classes.

Other inputs:

> The schools provide free medical, dental and mental-health services (students are screened upon entry and receive regular check-ups through a partnership with the Children’s Health Fund), student incentives for achievement, nutritious cafeteria meals, support for parents in the form of food baskets, meals, bus fare, and so forth, and less tangible benefits such as the support of a committed staff. The schools also make a concerted effort to change the culture of achievement, emphasizing the importance of hard work in achieving success.

These inputs are claimed as characteristics of a "high quality school" in the abstract:

> We conclude with evidence that suggests high-quality schools are enough to significantly increase academic achievement among the poor.

"High quality schools" (high quality meaning high test scores) generally do not fund many of these services for their students. What the study demonstrates are characteristics of schools that can help underprivileged children with less than adequate familial support.

This is an argument in favor of segregation. These services can only scale and be cost effective if a large portion of the students will use the services. This would not be cost effective if the majority of the school was not underprivileged.

home_boi··on Why a Dutch court stopped high school students from swapping schools (2017)
> mastering an arbitrary test

If the test is based on the standard middle/high school curriculum (if there is one), then it can be a fairly good predictor.

Otherwise, even if it is an arbitrary test, it takes study skills and discipline to be able to master it. I imagine that both of those traits correlate with performance at school.

home_boi··on Chinese tech giant ZTE ceases operations after ban on using U.S. components
> it outcompetes payment systems from American tech companies

Does it? I think American payment systems are winning outside of China/USA. Of course it won the Chinese market because China makes it extremely difficult for foreign tech companies to compete.

home_boi··on StreetLend.com shuts down, citing GDPR regulations
> The GDPR is about 68 to 90 pages depending on which language you're reading it in. It is trying to be futureproof by leaving measures defined in terms of 'current state of technology', 'reasonable security considering the risk' and other such ambiguous terms.

1 page or 1,000 pages, most people are not in a position to accurately interpret it and understand what does or does not comply.

home_boi··on StreetLend.com shuts down, citing GDPR regulations
That's a solid 50 hours of engineering and QA. At a $75/hr contracting rate, that is $3,750 (50 * $75/hr).

And that's just the engineering work. The website owner cannot know whether or not the engineering work and website meets the requirements of GDPR by himself. He does not have the ability to interpret the GDPR policies. The website owner would need to consult with a compliance lawyer or expert to assess the website for compliance. I would guess it would take a lawyer 10 hours at minimum (assuming the lawyer is a GDPR expert and already knows GDPR in and out) to assess a website for GDPR compliance, billed at a low $250/hr is $2500.

home_boi··on Text Embedding Models Contain Bias
If the biased models replace human decision making, then it just has to be shown that the models are less biased than humans which may not be that high of a bar to pass.
home_boi··on Text Embedding Models Contain Bias
The politicization of bias in this realm is unproductive. We know where it leads. There will be 'committees' of people who are not trained in statistical thinking, who haven't even taken a statistics class, who are not qualified to make any statements and who's interests are not in line with making the best product acting as nuisances and aggressors to people who are do have the expertise and who strive to make the best product.

The best course of action is to treat this bias like normal bias with non-politicized, inanimate objects. How would data scientists that encountered similar bias while running machine learning models of the motion of waves act?

home_boi··on A $76,000 Monthly Pension: Why States and Cities Are Short on Cash
What's the chances of retroactively lowering pensions?

1. Progressively lower pensions. Skim off the top earners.

2. Create projects for the community and declare that the saved money will be used for those projects for better optics.

This won't lower trust in government pensions by that much because this is just correcting what is seen as "unfairly high" pensions.

Technically users are entering their credit card information somewhere down the line after an ad click, many times on a website "shadier" than Facebook because sane advertisers make more money than they spend.
home_boi··on Publishers Haven't Realized How Big a Deal GDPR Is
> In fact, I think the author is underestimating the impact, right here: "Of course, making this change will have a dramatic impact on your revenue for single-visit traffic, because you basically have to design your ad model to work completely differently from how it works today."

To add to this, the quote paints complying with the legislation as a simple redesign. It would require much more than a redesign. The technical, administrative and legal costs of implementing the new system from scratch would be magnitudes higher than implementing the current system from scratch. And add on changing requirements as the legislation is in its infancy.

home_boi··on Publishers Haven't Realized How Big a Deal GDPR Is
I don't read news but I'm sure that GDPR would hurt the smaller, independent news websites or aggregators that people find reputable more than CNN, Fox News and sinclair group. The latter at least have TV advertising. Their website is just horizontal integration for them.
home_boi··on Publishers Haven't Realized How Big a Deal GDPR Is
I don't think the legislators understand the technical complexity it would take to comply with GDPR nor the benefits of tracking for the internet.

Tracking makes markets more efficient.

1. Advertisers can tune their ads/targeting to get higher conversions and sales. They pay higher PPMs and PPCs.

2. Publishers get higher PPMs and PPCs. This motivates them to invest more in their content and website because each new user will yield more money with higher PPMs.

3. Users get more relevant and safer ads. Remember the shady banner ads of the late 90's and 2000's? That's the type of low conversion rate / click through rate ads that will run when advertisers can't target their audience efficiently and PPMs are very low. Relevant ads also save users (the segment that buys stuff from ads) time from researching for products and services.

4. Users get personalized content from publishers. This has a few negatives but I would argue that it greatly improves user experience.

The technical and administrative complexity required for the legislation effectively shuts off tracking for all websites that aren't owned by a megacorp. Small and medium sized publishers now have less motivation to get good content out and improve their websites from the lower PPMs.

home_boi··on Stanford University data glitch exposes truth about scholarships
But they are not disadvantaged. Almost everyone who gets into Stanford and Ivy league colleges, underrepresented minorities included, come from very privileged upbringings.

The only disadvantaged population (overachieving children of poor immigrants, mainly European and Asian) is discriminated against through affirmative action in the admissions process and apparently also for scholarships.
