> What defines market making is the fact that you buy and sell the same commodity at the same time, taking advantage of the spread to make money.

You need not be a formal market maker to increase liquidity. Technically speaking even retail customers will receive small transaction fees for increasing liquidity in certain circumstances where it's particularly lacking. More generally speaking, any strategy that rapidly connects two parties is market making, even if the two parties are not immediately next two each other in the strategy's trading queue.

> Two other rapid transaction arbitrage strategies involve market manipulation, in which trades are placed that are designed to fool other trading algorithms into believing that the price is going to move a certain way

Market manipulation is not a good term to use for this, and it's a fairly serious accusation to levy against a trader. Market manipulation is an illegal activity that typically involves cornering or collusion. More abstractly, this is a net improvement in price discovery, because one party notices that another party can be fooled (which means their algorithm has a glaring pricing inefficiency). In repeatedly taking money from the other party, the other party becomes incentivized to stop executing that strategy. Once there is no counterparty to take that trade anymore, the inefficiency has been traded away, and the market is now (likely imperceptibly) more efficient.

> Neither of these two strategies create liquidity on the market, that is, offers more opportunities for anyone who wants to buy or sell to do so. Instead they seek to create, and/or exploit opportunities.

This creates liquidity. Any situation that increases trading activity increases liquidity by definition. You do not need purely symmetric market making to improve overall liquidity - if many low latency trades are being executed, and they are finding counterparties, the liquidity of that market is increasing as a result of the volume. HFTs do not buy and hold, which means they are rapidly connecting buyers and sellers, even if it individual securities are bought and sold asynchronously.

S: There are lots of sh--ty white male programmers working in the industry.

wpietri: Personally, I'd be very interested to see Damore's code. We already know that he lied about both a PhD and being a chess master. [2] I would not be shocked at all to find out that he's not good at programming.

You brought up Damore after the parent mentioned "shitty white male programmers". You speculated that you'd expect to discover that he was a bad programmer.

I'd like to see what wpietri's home life looks like. Based on his comments in this thread, I would not be surprised to discover that he's a terrible parent and has a bad relationship with his children.

Would you not find that a completely offensive and uncalled for personal attack? But I didn't lie! It wasn't an attack! It's not technically slander or libel or defamation, and technically is what matters. I just stated what I wanted to see and speculated based on some reasonable inferences. Oh, you don't think my inferences are reasonable? Prove it.
Don't misunderstand. That would be a way better movie than the last two even without side adventures. They're two of the very few movies in my life I've fallen asleep in the middle of. I don't do that often.
> if people decide to stay in the US they should try to assimilate

This is problematic. If you're a hard-working taxpayer who doesn't receive subsidies or cause a net negative on the economy, why do I care if you "assimilate" to my culture? In fact I'd rather you keep your culture proud and strong since it will make you happier and more productive. You may even encourage your hard-working friends to join you and make the economy even better.

("you" and "me" above are just rhetorical here...)

Instead of "assimilate", you can reframe your thinking to "be overall positive to the economy." I think that's what you intend but I could be wrong.

There's no evidence that one's implicit associations affect their behavior. Also the Implicit Associations Test used to determine your implicit associations in the first place is unreliable. Implicit bias testing and training is pseudoscience at best, especially when you consider that 95% of the professors in that field of study lean left.

If only consumers cared. As it stands there's very little downside to handing information over to government(s), and I would assume some upsides (back scratching).

Apple might actually be making consumers care in an odd way by making it such a public issue.
Conservative socially does not have much to do with religion. Chinese will often claim they “aren’t as open as” westerners for some definition of open. Most of my Chinese gay colleagues in china were in the closet, there was just no way you could be open about that, even in an american company. Otherwise, the cultures are very different, which can’t be discounted. Oddly enough, many things in china would be considered too open for Americans, so it isn’t clear cut at all.
It's not like most of those will be tolerated any better in China. I suspect it's more that some of their opposites are more accepted here, and if that offends you then you're more likely to leave.

The primary non-monetary reasons I hear for Chinese nationals to come to the US is for the air pollution and their children's schools. It's not like cost of housing is much lower in Shanghai, Beijing, Shenzhen, HK...
RSUs are not necessarily better. You get taxed on those as ordinary income. If the grant is large enough, you're effectively stuck with paying tax on an illiquid asset. With options you're only taxed at the time of exercise. So in the case of the 2014 grads, they'd be underwater on the value of their options vis-a-vis the exercise price, but wouldn't necessary have any sunk costs provided they haven't exercised any of the shares. The downside with this situation of course, is that the employees have "golden handcuffs" since if they leave they'd have to exercise within 30-60-90 days or lose their vested, unexercised, options.

For those employees that did exercise their underwater options, one small silver lining is they can write those losses off on future tax returns.
Trashed: Inside the Deadly World of Private Garbage Collection
> What you have to understand as a baseline is that AEI is a partisan think-tank, so they're not telling truths or exploring the spectrum of interpretations, they're coming at any given issue with an ideologically driven mantra. And in this case, that mantra is that the commerce clause of the constitution, which states:

First, AEI is not a partisan think-tank. They're ideologically conservative, but they are non-partisan.

Secondly, it's hard to argue that advocating the Commerce Clause is an "ideological" or partisan viewpoint. A hundred years ago, it definitely would have been, but not in 2018. If anything, the current interpretation of the Commerce Clause is the antithesis of conservative ideology: it expands federal powers, limits the rights reserved by states, and (if you want to make things partisan) predominantly happened because a Democratic president nearly caused a Constitutional crisis when he tried to stack the courts in order to get court rulings in favor of his agenda.

I'm an advocate of net neutrality, but I'm not going to say that the position being advocated here by AEI is a particularly partisan one. If anything, they're smart, by framing a Republican-sponsored policy within the context of case law that Democrats have consistently supported for a century.
I'm actually very interested in setting aside some storage for this project but have legal concerns. Namely, if an encrypted shard of [illegal file X] is sitting on my IPFS node without my knowledge, could I be held responsible legally for holding/distributing that illegal file? As far as I've been able to ascertain from a few lawyers I've curbsided, the answer is "maybe," but if anyone knows of any clear legal precedent around this issue, I'd appreciate your input. Seems like this issue could preclude mainstream adoption, if not addressed (maybe it has been and I just haven't seen it).
> You do not need to hate women to be sexist. You do not even need to be aware that you have biases for those biases to be affecting how you act.

I am aware of that, good to point out though. However I was wondering because the wording "you can still maintain the discrimination" implies awareness and perhaps conspiracy. For example if I was talking about "implicit bias" I might have said something like - "it doesn't modify existing implicit biases and institutional constraints, which have been responsible for ...". But even then it would be good to see what exactly those biases and constraints are at Google.

On the topic of "implicit bias", it's also useful to add that it doesn't have to be just a personal "implicit" bias, it could institutional as well, incentives and rules that combine to exclude certain groups more than others, in this case women. Though then it's not clear how they would fix it, given that it's implicit. Maybe hire an outside consultancy which will be able to identify it better (since they are not part of the culture and not affected by same incentives)...

> I also never understood why the barrier is set so high for giving any other species but ourselves credit for being intelligent.

Because the Western intellectual traditions of both science and philosophy arise from European Christian religious thought, which regards Man as made in the image of God, set apart from and above other animals.

The psychology of animals is one of the areas of scientific study that is still today struggling out from under its cultural roots, to be truly empirical about things.
>Blue states still have better public schools than red states

I don't think the metric used gives the entire picture. It's pointing out the percentage of nationally-ranked schools and ignores everything below that threshold.

>So even if they are sending them to private schools, the public schools that "they won't send them to" STILL do better than the public schools in conservative states.

The urban school that the wealthy whites are avoiding probably isn't nationally ranked.

>for their desire to defund public education

Who wants to do that? It's about the amount spent, not defunding.
Thanks for this detailed explanation. The Simpson's Last Supper analogy really made it click for me.
Again, that's perfectly fine and reasonable in individual situations. It's also not an argument for society getting more education as a whole. The tie-breaking for you is the same whether it's between high school diploma vs bachelor's degree, or a bachelor's vs master's. Making the high school degree holder get a bachelor's and the bachelor's get a master's doesn't help society as a whole.

Yes, I was assuming a cryptocurrency situation in which the system is open, new participants can join, and it must work under byzantine fault-tolerant conditions. In a system such as RAFT or PAXOS this isn't the case and thus these systems can properly elect leaders.
Right, making it doubly confusing to use a culturaly bound one dimensional adjective to describe differences between people of wholly different cultures. It’s not a meaningful comparison.

Edit: I suppose my confusion is incorrect...?
TBH, another factor to be kept in mind is that most foreign students are doing a MS in US only for the work visa.. if the possibility of working in US went away (say OPT extension gets terminated and everything else remains the same, or Trump pushes through with making H1B's much tougher\impossible to extend beyond 6 years ), a lot fewer foreign students would come to US which would result in fewer profits..
That's a fair point, but somehow the nervous feeling isn't limited to sharing CPU time with strangers!

The great thing is that you don't have to! There's plenty of other people that are happy to do so and report their findings. The app would be outed as fast as other software that has attempted to send personal data without disclosure (Windows telemetry, Samsung TVs, etc.). I doubt Echo could ever get away with sending everything to Amazon's servers. And if you don't trust that others would do that, then you just don't have to use it, or use alternatives like Shazam.

Why? If those scholarships were awarded on merit (they likely were), why should they be based on where the tuition waiver is "used?" Exceptional undergraduates provide value to the school while being in it as well as what they do after finishing their education.

These scholarships were almost certainly awarded by the institution, not the federal government.
I had a hypothesis: the damage done by a ship in hyperdrive doesn't scale linearly with mass. Anything under a given threshhold is basically a mosquito bite, and large capital ships such as the one used in The Last Jedi are too expensive and valuable to be used in such ways.

Not necessarily. Excluding interest, taxes, depreciation and amortization (EBITDA) is a common financial metric. It can demonstrate a business model is working, before taking in to account capital structure or other semi-external factors.

> Because the AEI is a right-libertarian propaganda mill (or, if you prefer, “think tank”) that generally (though there are some prior exceptions, too) is in lockstep with the general right-libertarian minimalist interpretation of Commerce Clause authority

You'd be hard-pressed to find an ideologically libertarian person well-versed in Constitutional law who wouldn't concede that regulating interstate commerce at the federal level is covered under the Commerce Clause.

There are other grounds on which to have the discussion about net neutrality besides the Commerce Clause - and proponents of net neutrality would be well-advised to shift the discussion to those terms, because if we're strictly talking about the Commerce Clause, it's about as clear-cut as things get: the federal government has the power to regulate explicitly-interstate commercial activity.

While I agree with both of your points individually; I fail to see how your two points are connected.

I'll try to take a stab at this. I'm Chinese-American and I feel the Chinese folks who come to the US to study or to work have very different mindsets.

I have a friend who is dating a lot in NYC and he told me he notice most of his Chinese-American friends are liberal as in we fight for freedom of expression and social justice. Whereas the girls he met who are newly from China are conservative and support Trump because they are pro-business and more money-driven.

Based on his observation and my own experience I would agree. Most new Chinese visitors or immigrants don't value social rights and freedom of speech. And to be a bit critical, I feel they are so used to having the government or authority telling them what to do that they are comfortable with authoritarian rules and don't understand the importance of having independent thoughts and diversity.
Dunning-Kruger effect explanation should be in every single high school education program.

> My friends went back to China because the US is incredibly unwelcoming to hard-working immigrants and provides no reliable path to citizenship or permanent residency besides fraudulent marriage.

China is far more unwelcoming to hard-working immigrants and provides no reliable path to citizenship or permanent residency even if one is willing to marry for it. Unless you're very wealthy or famous, it just doesn't happen.

It's not easy to be an immigrant just about anywhere, but as closed as the US may seem, it's not even in the same league. The US grants more people green cards and citizenship each month than China has ever.
Operators have no interest in being reduced to "dumb pipes" (as the industry calls it). So OP is correct, P2P overlay routing has traditionally caused headaches for network operators traffic shaping.

Claiming implicit bias is a very well greased slope towards a bad end because it lets you say (your opinion is that) someone else's actions show a pattern of whatever-ism and that they are not credible because of it and they cannot defend themselves because their whatever-ism is not consciously applied.

Just because brogrammers want to promote other brogrammers does not make them whatever-ist. Claiming that implicit bias is a type of whatever-ism is just BS doublespeak like "if you're not the solution you're the problem".
