As far as I know the theory does not completely exclude time-reversal formulations of QM. Non-symmetry of quantum measurements has not been experimentally confirmed.

The only confirmed T-symmetry violation is that of K and B mesons, I think. But that does not follow from quantum theory I think. It's experimental result.

Is this really specific to Robinhood? If I go to https://investor.vanguard.com/investing/online-trading/order... and follow the "View the quarterly reports" link, it shows that Vanguard routes orders to these companies: Citadel Securities, VIRTU Americas LLC, G1 Execution Services, UBS Securities LLC, Susquehanna Capital Group, Citigroup Global Markets

Wikipedia says Virtu Financial is an HFT firm: https://en.wikipedia.org/wiki/Virtu_Financial

Edit: yet, the same report (as well as a document that the article links to) says "Vanguard Brokerage does not receive compensation for directing order flow in equity securities". So Vanguard routes to similar companies, but doesn't get compensation from them?

Are you sure about this? This sounds very weird. I understand that you might be required to public your annual profits, but an actual trade list?
Thoughts occurring to me: browser devs (Chrome, Firefox, Safari, Edge) aready serve as a link in the CA trust chain, in that they can decert a CA.

Browser dev as CA cuts out the middle man.

I'm not sure where I stand on this, though I'm somewhat concerned.
2%. Seems crazy low to some, but I put very conservative numbers in my MonteCarlo simulations.
1) "About 10% of new Hepatitis A and 20% of all new Hepatitis B infections in the United States are among gay and bisexual men" (CDC, https://www.cdc.gov/msmhealth/viral-hepatitis.htm) -- that's a much higher number than the incidence of gay and bisexual men in the overall population of the US (2-5%?).

2) "Gay and bisexual men and other men who have sex with men have the highest prevalences of
gonorrhea, chlamydia, and early syphilis." (SFDPH, https://www.sfdph.org/dph/files/reports/StudiesData/STD/SFST...)

3) "Men who have anal sex with men (MSM) are more likely to get anal HPV than men who only have sex with women. Researchers estimate that the prevalence of anal HPV among men who only have sex with women is around 15% while anal HPV prevalence for MSM is around 60%."

"the first three would be multi billion dollar companies

I think this is the problem. Google does not care about products smaller than that. They will happily shut down a product because it's too small, even though it would be a reasonably successful business on its own.

However, "reasonably successful" is not good enough for them.
It's perverse that we've accepted as OK, taking the concept of movie regions, to books.

It is a corruption of good ideas into bad ideas. These things should be called rentals at the time of sale.

Ask HN: Do purely ad-based web sites still make sense?
It looks like even with 1M monthly page views, it would be tough to generate $10k. It seems like it'd be pretty tough to market a website to that level.

I have a service I was building just for myself to fix some problems with online movie, tv, book, etc reviews -- sort of like FakeSpot -- but after doing the math, I'm wondering how much energy I should put into marketing it. The upside seems pretty low, and the costs can be quite high...

Does anyone have any success stories with an ad-based website?
I think that discounts the vast area, number of landmarks and tourist attractions, and multitude of different sub-cultures inside the US itself. When you can drive somewhere new and interesting in a few hours, and don't need any paperwork or currency exchange and don't have to worry about the language, that's much more appealing than expensive and time-consuming overseas flights.
I am aware of no such loopholes. Foreign assets can of course be hidden from the authorities, but they will be confiscated if discovered. Any shares in companies or properties will be confiscated and liquidated, as will any payouts from life insurance policies and such. (Unless I'm very mistaken, all income counts).

As will any primary residence if it has a higher standard or price than the sustenance minimum, any vehicles not required to perform work, any household items beyond a minimum of ~$10k
or so in value. It's quite harsh.

If married, the spouse can keep 50% of any assets that were jointly owned.

Electricity provider market is an extremely dodgy one, e.g. in Germany one is receiving random scamming calls trying to make the victim change the electricity provider. One such scheme was revealed some time ago - someone incorporated in Germany and Switzerland, then hired German speakers somewhere in Serbia where the scamming call center was located. Plenty of dodgy entities profit fortunes while electricity cost for individuals regularly increases.
The last few paragraphs contain the “so what?” Even so, it doesn’t really explain. It just says that HFTs exploit their retail customers. Does anyone know how?

Your comment implies maybe the benefit can be found in unfair bid ask prices. Are they doing something like:
1. Buy their own shares of xyz.
2. Execute your buy order. Which drives up the price per share fractionally.
3. Sell their shares of xyz.

This is total speculation. I have no expertise in this area.
I don't think there's a requirement to publish a list of the actual trades performed, but I get the impression that the reporting requirements are more detailed than just a profit/loss number.

For private individuals, the only public piece of information that will be reported is the amount of tax paid, and the net assets of the individual.
Partially (that's the perl lvalue solution), but the problem shouldn't be solved by cheating, but by implementing a symbolic logical solver, like computional algebra sytems (Maxima, Sage, ...). To free $x on the left side square both sides.

{ use logic;
sqrt($_) = 12;
print solve($_);
}
=>
$_ = square(12) = 144;

This is usually done by providing prolog-like rules for each and every operation, where many ops could provide more than 1 solution. Then feed them into a solver for more speed. Like with picat or cbmc.
Lisp is perfect for that. With perl it gets hairy, but still should be possible.

> arrogant to assume that you have any clue what they did

I know what they did. They’ve made an 0.5GB mobile app that downloads some data from a server, and displays it with a nice 2D rich GUI. I’ve wrote a few similar apps, both for iOS and WP.

> the constraints they had

Again, I know most of the constraints they had. Unlike PCs or especially lower-level platforms like game consoles or embedded Linux, at least 50% of these constraints are dictated by Apple and should be known by every developer with the access to iOS SDKs. Other constraints are dictated by internationalization, Asian languages and RTL layouts indeed complicate a few things, but not enough to justify the size. Same for multi-platform development, data caching, and security & privacy constraints.

The only thing I don’t know about these constraints is their client-server protocol (not because I don’t work in FB, it’s possible to reverse-engineer with a sniffer, I just never cared). But if it’s network-related code that’s so complex, I would consider making a server-side proxy, to expose mobile-friendly protocol. BTW I did that too, when I was working on mobile bank clients.

> or the kind of people they hired while developing it

I agree with you on that. I don’t know anything about FB, I‘ve just guessed about it.
Buying digital media with DRM is a mixed bag. For eBooks I sometimes buy directly from publishers to get no DRM versions, but for Google Play movies, Kindle and Audible books, iBooks, and Play books I most factor the risk of loss of access into the price/value purchase decision.

Buying DRM media from multiple companies is also a good hedge-my-bets strategy. At the other side, renting access: I am a big fan of O’Reilly Safari. For a yearly fee I can read their library. Much of my job and career requires me to stay current with new tech and I generally prefer reading or skimming a recent book to reading miscellaneous stuff on the web.
Kejetia Redevelopment: KMA Sets Committee to Validate Traders
At many (maybe most?) consumer brokerages, your brokerage doesn't actually place orders on actual markets. The markets are super complicated! The job of a modern brokerage is to take customer orders, maintain customer accounts, handle expensive telephone support, and pay internalizers.

Internalizers do the job you might think of as the core brokerage job. They take raw order flow from brokerages, track the actual prices of securities on exchanges, maintain an inventory of their own, and decide where orders should execute. It's an extremely technical job. Citadel is, I think, still the biggest player here?

The most important thing to understand about retail order flow is that it is dumb money. The sharks that market professionals worry about do not as a rule place orders with Schwab or Robinhood. In particular, if you make a market in a particular stock, and an order routed from Robinhood comes in, you don't have to worry that it's a whale moving a giant block of that stock in advance of some fundamental or technical news item you're 2 seconds behind on.

As a result, an internalizer can tune its pricing for retail orders: retail customers get better pricing, because the internalizer can access a better spread (the difference between the lowest price they'll sell for and the highest price they'll buy for).

You may or may not be fully cognisant of how your field is actually practised, which the original commentator obviously is.

I have lost count of the times that senior people in your field, have happily admitted how their research is targeted towards the desired outcome of its funding source. Which the people funding the research are fully aware of, they just go economist shopping for whatever result they want to back their policy decisions.

The real issue with current economics isn't that it's not a science, it is that it's not practised scientifically. Those who do look at the field scientifically, have learnt a very great deal from the 2008 debacle - but they're not getting published where anybody is going to read them. But that is far from new. Let me present one of the great, sadly overlooked papers of your field:

David Jones, Emerging problems with the Basel Capital Accord: Regulatory capital arbitrage and related issues

https://www.sciencedirect.com/science/article/pii/S037842669...

Written by a researcher at the Federal Reserve in 2000, he pretty much nailed the causes of the 2008 crash, at least 8 years in advance. His reward was that he got to be part of the cleanup judging by his subsequent career - efficient resource allocation indeed.
You can access the paper on arxiv: https://arxiv.org/abs/1802.10498
I think the point here is to understand why such a response occurred. So it's very much on topic. Nobody is denying that this is generally a bad thing for the commoners. But when you put it into perspective, what the US and China have been doing are also very bad. So this is nothing out of the ordinary really.

The day I was sold on ditching the headphone jack was actually last week when a giant wave surprised us and nearly washed my wife's (brand new) phone away at the beach. We took it back to the house, rinsed all the sand and salt water off under the tap and it never had a single issue.
At https://investor.vanguard.com/investing/online-trading/order..., if you follow the "View the quarterly reports" link, it shows that Vanguard routes orders to these companies: Citadel Securities, VIRTU Americas LLC, G1 Execution Services, UBS Securities LLC, Susquehanna Capital Group, Citigroup Global Markets.

It also says "Vanguard Brokerage does not receive compensation for directing order flow in equity securities".

But the SeekingAlpha article criticizes Robinhood for routing to Citadel, calling it a "market makers that also have high frequency trading arms". So Vanguard routes to similar companies, but doesn't receive compensation? That doesn't really seem better for the customer to me. What am I missing?
> Ok, if we demonstrate that the movement of the planets is not accurately predicted using a well loved system is it appropriate for us to be held to having to invent a new system before publishing?

Absolutely not! That would be irrelevant, out of scope, and completely unreasonable.

I see only total hypocrisy and double standards here. Just admit that every country has their own set of laws regulating the internet and that the US is no different. Or are people so institutionalized that they don't even realize the countless censoring going on around the place?
>it’s really just an alternative syntax for C#

That's very true. Either C# or VB.NET, you're programming the NET Framework. All you can do in C# you can do in VB.NET, and even there's some features that are better implemented in VB.NET, like Type.Missing https://blogs.msdn.microsoft.com/eric_carter/2004/04/15/type...

Of course any language with "Basic" in its name will be look down, but in today's NET there's no objective reasons to do so. Nowadays, VB is a better choice than C# to develop in-house business management software.
Eventually I failed to see much difference if Inbox and GMail app. I just deleted Inbox because it seemed redundant. Gmail isn’t that good either with their auto categories.

Yes very similar. By knowing the orders Robin Hood sells to the HFT firms prior to execution they are better able to exploit the market bid and ask sizes and orders and Robin Hood customers could end up with worse fill prices
I agree there can be significant overlap. I do not agree that every case of resource allocation is a power distribution. As a case in point, there is a question that HN often asks -- what should I set my consulting rate at? This is inherently an economics question, and there is not often a power distribution discussion of whether the consultant has unique skills that let them charge what may seem to be outrageous sums, or if the consultant is freelancing in common skillsets.

Another point to be clear about is that economics is not solely concerned with resource allocation. Welfare consequences of policy, counterfactual reasoning, causal inference, algorithmic game theory and mechanism design, etc. are all research areas that are applicable to resource allocation but not only used for such.
Yes. Some sites as well as apps use it (so scraping the web pages is not required).

I live in north Nanshan and spend about that much per day on food and I am not very frugal and don't cook myself. If you want the cheapest food it would be about 15 rmb per meal or less, so 83 rmb per day is a very decent ration, unless you only eat western food of course.
And that's different from all the other retail brokerages, which charge trading fees and route their orders to Citadel like everyone else does, how?

Also, what kind of trading are you doing with Robinhood where you're sensitive to the theoretical 1-2 cents this supposed Citadel trade is taking out of your hide? Would you be happier if Robinhood just charged a 2 cent trading fee?

After the events of the past few years, I don't think it's tenable to cast the problems Peterson highlights as occasional and obscure. Look at FIRE's speech code analysis: most universities have administrative restrictions on free inquiry. Look at Heterodox Academy's work on ideological bias: social science is 90% left, with something like 30% (from memory) calling themselves "radical". Look at the current replication crisis, which arises in part from fabrication of ideologically convenient results.

I simply cannot agree with your assertion that Peterson et al are cherry-picking and that academia is fundamentally sound. These pathologies are too common and too widespread not to constitute some kind of systemic issue. I find your arguments unconvincing. Instead, I believe that a correction is long overdue.

Disciplines that reject reason, empiricism, and rigor, that claim all truths are equally valid, and that hold the only valid goal of pedagogy is tearing down power dynamics --- these are indoctrination, not inquiry, and the public should not fund this activity.

> no dissenting voices are allowed to exist on the left or in academia

Academia really does apply extreme social and political pressure to unorthodox thinkers. Look at the campaign against Rachel Fulton Brown.

> use Peterson and his theories to justify

It's become common lately to argue that we shouldn't acknowledge certain facts because unscrupulous people might use them to justify something bad. This position is not tenable. The truth always gets out, and when it does, those suppressing it lose all of their influence and credibility. It's far better to acknowledge facts and work with them.

> This fund is supposed to cover all of the margin trading misfortunes

The fund is a first line of defence once a member’s assets fail to cover their exchange obligations. It is intended to quickly deliver capital to avoid market disruption. After that, there is a waterfall [1] which essentially comes down to Nasdaq’s members footing the bill.

Mutualised losses were the original model. It took time to activate, however, which in a T+1 or 2 settlement world is likely to cause = disruptions. The fund was implemented to provide a fast intermediate short-stop for medium-sized (i.e. big, but not systemic) losses.

The system worked as intended, today.
