That could be verified by looking at first-generation SAT takers, eg immigrant families or perhaps historical data from when SAT wasn't so common in the US. It seems extremely intuitive to me that families with higher income raise children that have higher SAT scores though.
It's a losing battle. I've had lots of experience with this.

Here are the possible scenarios:

1) You will never finish
2) you will finish, but many times over the deadline
3) your customer will blame you
4) you will lose money on the project

Get the requirements in writing, don't allow the customer to keep changing it. If they want to change it, make sure you let them know how much money/time it will add onto the project.

Isn't it pretty easy to determine if there is racial bias in admissions?

Isn't the fact that Asians need to score a couple hundred points higher on SAT score just to get admitted enough evidence that there is bias?

Correct me if I'm wrong, but at Berkeley where Race is not considered in admissions, Asians comprise like 50% of the student body. I'm pretty sure you'd see similar numbers at all the elite universities if race wasn't an issue.
Also, I'd really appreciate any feedback - please let me know what you think. :)

Sometimes i had a 5-10% ping loss between servers in the same Hetzner datacenter, so not being on the same rack can be a problem. Especially if you are using nginx -> backend. Then every request is a TCP connect to the backend server, and when SYN packet is lost, you will have a 3 seconds timeout (at least on FreeBSD TCP stack).

After "you sell your stocks"

Person1: Has equity worth $100
Person2: Has $100 cash.
Person3: Has Tbond worth $100

After "you go and buy treasury bonds"

Person1: Has equity worth $100

Thanks for taking the time. I am familiar with the argument that they would replace SRAM, speeding up the chip. I am familiar with the argument that they would be lower power. My frustration with the discussion has always been that faster/bigger SRAM does not equal a fundamentally different computational model or radically different architectures, which is always what memristors are claimed to bring. Sure, it could be worth a huge speedup, but what does that have to do with antiquating the von Neumann model?

I was not aware they could behave as both memory and logic; perhaps that can contribute to a fundamentally different structure.

Are you suggesting that affirmative action should be based on family income, then? Seems like a good idea to me, but I might be missing something.

I'd be interested in a break up of admission statistics, SAT scores, race and family income for the Ivies. because I'm not entirely convinced that just because SAT scores follow family income in the general population, the trends are exactly the same among admitted students.
A similar thing happened with SOPA. The original version was really vague and looked like it could be applied to domestic sites. Some parts were clarified and became much watered down. That still didn't make the watered down version a good bill, but everyone was still bashing the old version.

A question that I find interesting is: would the bill have been so clarified and watered down without all of the people getting irrational about it?
That's not really needed, when the universities proudly proclaim their commitment to diversity and a well-"balanced" class, which of course requires uneven application of objective measures to different subpopulations.

Good data for the performance of hedge funds as an asset class that account for survivorship bias is somewhat hard to find. Off hand, Swensen in "Unconventional Success" recounts that for a single decade period that he was looking at, third quartile managers matched the market before fees. So after the standard hedge fund fees investors in those funds underperformed the market by about 1.6% (in his specific decade-ending-dec-2003 time series example).

Looking backwards, you can always identify fund managers that beat the market, but only in hindsight. One big part of this that's left unsaid is that yes it's possible to find managers to beat the market in hindsight, it's finding these managers ahead of time that's difficult & unlikely. Coupled with how much you'll trail the market if you try and don't succeed in finding outperformers ahead of time, it's a bit of a losing game to try.

There's an entire other field of study about the persistence of performance, but suffice to say that looking in the rearview mirror for last decade's outperformers doesn't help you find the next decade's outperformers.

The thing is, admissions to elite universities is almost never about test scores. Immigrant parents from countries like China and India are used to test scores mattering a lot. In those countries, your absolute score on the National Exam determines not only your placement into a university, but also what fields are available to you for study.

The SAT is nothing like that. If you walk into Harvard or Princeton, you'll find that most of the kids got above 2300 on the SAT, and a ton had perfect scores. If you tried using the SAT to distinguish between members of the student body at either place, you would have little success. The admissions committee has the same problem, so, kids are not selected based on SATs. You get in because you're good, or at least, you show a lot of promise, not because you can study for a test.

So yeah, maybe asians have higher test scores as a cohort, but maybe they also have less other things that are equally important -- sports, focus, passion, alumni connections, etc. These things count just as much in admissions decisions.

It's possibly to argue that selecting for these things is inherently racist, but I mean, what isn't? The SAT itself privileges a white collar suburban education. Who's to say it's more valuable to be able to memorize vocab, or do arithmetic than to run or paint?

You're asking me to pay $5 for a one-page PDF that's the first chapter of what sounds, in the absence of any information about it other than "I'm writing a book about my startup", suspiciously like an advertisement. After spending a few minutes clicking on links I was finally able to figure out what it is that Gumroad actually does, but neither your blog post or the purchase page gave the barest bit of information about the startup you're writing about.

I'm interested in what you're doing and would love to hear what you have to say, but it doesn't seem to me like you're doing a good job selling the book concept to someone who isn't already familiar with you or your work.
This is a cool project, but the title of the book is very mis-leading ("Building a billion-dollar company").

Without knowing the author, people might presume that this book is written by someone who has built a billion dollar company before, and thus hand over $5 only to be disappointed (since they can't preview chapters). Not to mention it's a little link-baity.

Why not just call it "Gumroad"?

Because we used the inflows & outflows of a couple large retail mutual funds as proxy for investor demand, you're right that the story actually is "retail investors are bad at timing the market".

There's a whole other set of data to dive into whether or not professional managers as a whole are bad at market timing (spoiler: they are terrible at it), but you're right in that this is not what this data set addresses.

Really the point the article is making is that on the whole, you and I, the investing public, shouldn't try to "read the tea leaves" and pull our money in and out of the market / move money around in the market because of what we believe will happen in the near future. What this data proves is that this doesn't actually work.

No, because SAT scores don't determine admissions. A schoolmate of mine with straight A's who scored a perfect 1600 SAT was rejected from Harvard, because he had essentially zero extracurriculars.

Schools like Harvard and Princeton look both for well-rounded students ("future leaders" they call them), as well as diversity in their student body. This means they won't accept, for example, 100 top violin players in the same class, no matter how impressive their individual applications are. Instead, they want a complete and balanced orchestra, for example.

So if, hypothetically, Asians tended to disproportionately cluster in the same extracurricular activities, or have less extracurricular activities, then there would be a very valid non-race-based explanation for the SAT gap.
Causation is measure of the extent to which they contain different information.

Assuming a college wants to admit a student with high "intelligence" or intellectual potential, which cannot be measured directly.

If high income causes high SAT, and high intelligence also causes high SAT, then (low income, high SAT) may well indicate much higher intellectual potential than (high income, high SAT)

If high income and SAT are both caused by high intelligence, then there is less (intelligence-related) reason to prefer (high income, low SAT) or (low income, high SAT).

You have no way of knowing how true that is.

Distribution of talents (as you mention) among the applicants, and luck (a larger factor every year that the US population grows but the firstyear class doesn't) are the main factors.
Ahh right ... I see where you're going but that's not the case with this. Its just a back and forth trying to nail down the specifications for the project. Once those are set, we don't change them unless they go through a change request process that we have. They're good clients I promise :D

The issue is just trying to track when a small requirement like

changes or is removed entirely.

just as an example of course.
> Well, how do you distribute trust? Do you have a quorum or something?

Basically, yes.

> Consider this ... what if I wanted to introduce doubt that X is really verified, and thereby hurt their business. How can you avoid me doing stuff like that? Besides harsh laws of course.

By not trusting you.

Right now, what happens is the browser and/or OS vendor determines a set of certificate authorities to declare "trusted", and all certificates they issue are simply assumed to be valid.

Instead, we could require, say, three signatures, each from different authorities, to invoke the normal "this is a secure connection to a properly-identified website" behavior.

But each of those authorities was still determined by the vendor to be trustworthy. It's still going to be the likes of e.g. VeriSign, Comodo, StartSSL, etc.. It's not going to be you.

Do you mean with respect to identification/segregation of content by content providers, or with respect to geographic entities' attempts at censorship? Or do you simply mean more and/or more prominent sites using country code TDL's?

The second, of course, we have. (Quip: "China was the prototype.")

The first, with attendant variation of content (i.e. you get a different view of an individual Blogger blog depending upon whether you are e.g. in Sweden or in Italy) seems rife for efforts to more quietly and piecemeal "pick apart" the Internet's "common voice".

Perhaps I'm being alarmist. But placed within the context of everything else that's going on right now with respect to Internet communication, it's worrying.

The third I have no real problem with, although I find the many attempts to use country code TDL's to make "catchy" domain names to mostly be ineffective if not annoying. (I'll leave that at the level of personal preference.)

Wow... I wonder what the Ivies would look like if admissions were 100% merit.

No legacies. I think there would be FAR fewer trust-funders.

And MIT's 'Chocolate City'...pretty much gone.

I suspect they would be very Asian places with a smattering of Jewish students. I think I can see why they would give ... say ... a Colorado snow boarder a few extra points. I think there is something that he brings to an Ivy campus...though I can't quantify it.
Assuming there isn't some form of self-selection going on. Asian students may be favouring Berkeley and comprise a relatively larger proportion of the applicant pool there when compared to Harvard/Princeton. In other words, your conclusion assumes that relative make-up of the applicant pool is the same everywhere and it very well may not be.
Remember also when you're using SSH socks proxy that all your DNS requests go through the un-proxied connection -- unless you're using Firefox, in which case you could set network.proxy.socks_remote_dns to 1 in about:config.

Another point is that most firewalls block most ports, but usually not 443 (https). So set up your SSH server on port 443. Since all traffic to 443 is encrypted anyway, you're less likely to raise suspicion.

> That would greatly raise the cost of the SSL certificates.

$0 x N is still $0, and the difference between 1 EV certificate and 3 EV certificates is not going to put anybody who really thinks they need one out of business.

> And I don't think that would be something that you could get the various providers to even agree on.

Put simply, certificate authorities don't have a vote. It's up to the browser and OS vendors to set their own requirements for default trust.

If Google, Microsoft, Mozilla, and Apple declare that all SSL certificates lacking at least N valid signatures are treated by default as invalid, that's the ball game. If the current authorities don't play along, new authorities will.

Edit: I should also note that there's really no need for anybody to play along. You can ship a CSR off to as many authorities as you want for signatures, then assemble those signatures and your certificate in whatever form is used by your server and the browsers. The only possible response by an authority is revocation of their signature upon discovery that your certificate has been signed by other authorities, too. Such an action would make them a laughingstock.
