HFTs don't arbitrage the single person day trader because those guys are are like a mouse farting in a hurricane. There is no point trying to identify and scalp someone who trades at most some $ millions a day, unless the person is doing it on really swampy stocks with no liquidity. Even then, the capacity in those markets for HFTs is also extremely limited.

HFTs will target big insitutional traders who have to shift a billion dollars at rebalancing time in a single day.

Even that is a dying business today because they themselves have been arbitraged away to a degree.

The Seattle subreddits are so bad about this. There's one with ~200k subscribers that is basically only sunset pictures and requests for good food. There's another one with ~100k subscribers with slightly better submissions, but every comment thread has the same 10 people brigading from a THIRD Seattle sub that focuses on alt-right politics.
Media outlets need to start hiring folks who live outside of a handful of trendy metro areas like New York, San Francisco, or DC (or in this case, Toronto).

It's quite obvious that the author has not spent much time in the types of communities where most people actually live, nor does he seem to have much familiarity with the concept of child rearing.

I'm not going to load my young children and 12 bags of groceries onto some pay-by-the-mile micro scooter. I'm going to use my minivan.

Has the author ever even installed a carseat? If you have children under the age of 10 or 12 then things like Uber, Ridesharing, etc. are pretty much out of the question due to laws around car seats and child safety.

Urban planners have been trying all manner of sticks and carrots (mostly sticks) to get people out of their cars for over 30 years now with very little success, outside of a few very high density older metro areas like London or New York.

Cars are popular because they give people convenience and flexibility that the didn't have before. Very few people are going to give that up voluntarily. This is doubly true when you have children.

If the author is going to pontificate on the future of transportation, he may want to think about the giant chunk of the population living in the suburbs and raising children. Otherwise it's just an article about the future of transportation for childless professionals living in trendy cities built before WWII.
Corporate surveillance is only a problem because it will sooner or later feed in to government surveillance. If I could wave a wand and stop that happening I'd be fine with corporate surveillance; I'm annoyed but not threatened by the idea that someone will study my every movement trying to sell me things I want. I'm threatened if the extremely arbitrary government decides that I'm an undesirable for some reason.

> corporations that have achieved enough power to exert de facto governmental control

Might be a failure of the imagination, but I really can't see myself ever getting involuntarily dragged out of my apartment by McDonalds employees. The worst I've ever seen a corporation do is set the police on someone. As long as the government is functioning sensibly a rogue corp can only do so much.
In addition to the many good answers here, I'd add that whatever parameter represents "diameter" for a proton, probably also represents the classical diameter of something macroscopic like a billiard ball if carried to that extreme.
He leaked it all to journalists he trusted to make decisions about how, when, and what to publish. It's not quite the same.

Plenty of interested minds put that together and don’t come to the same conclusion as you, my friend.
You have a great point, but what f a big company in the sector that already have the structure go after it and can implement pretty fast?

I am glad Kasparov and Deep Blue is mentioned here. Kasparov still does active research in chess (and especially computer aided human chess). And all the while I was under the impression that chess had been "solved" in the 90's...
Sure. But this is the responsibility an employer must take on in order to hire someone’s labor.
They're not carving out high-skill professions. You'll notice that doctors aren't on that list. They're carving out professions that are already under special regulatory regimes that affect how they're able to sell their work. In part because people/businesses are required by law to contract with people who hold these licenses. Like you cannot build a building without a licensed architect and civil engineer.

There would be an uproar if you couldn't renovate your office without hiring an architect an an employee.

Edit: Looks like the final version is way different than this quote. The final list of exemptions are:

- physicians and surgeons

- insurance brokers

- securities brokers

- direct sales under specific (previously existing) conditions.

So looks like they didn't really care about professional services after all but carved out industries where you look like an employee but operate a tiny little business inside another one.
I remember that story. It was talked about a lot here: https://news.ycombinator.com/item?id=18886804

The Fi team cares a long about these kinds of issues and does what they can to solve them. I cannot comment on specific cases, but as someone that works on Payments @ Google, I've seen the Fi team advocate for their users a lot to get things running smoothly. They deeply care about good experiences and do what they can to make sure that's the case.

Sadly, things sometimes go wrong, and it becomes a learning experience to make it better for users in the future.
> What if we state that a monopoly that makes up 75% of market is worthy of being broken up? Then some wealthy business owner will gladly split their company into two companies which they both own before hitting the 75% mark.

That's a "trust". That's explicitly what "anti-trust" is for.

As a poker player this is exactly what i was thinking. Poker is probably more winnable though because you arent competing against super computers with ai built by a team of highly paid mathematicians.
While I agree that day trading anything is an extremely poor idea- why is trading by banks/hedge funds/Goldman Sachs etc. consistently profitable? (Or if isn't profitable, why do they do it?) Is it just the massive informational advantage that they have? I'm not advocating for trading per se (I certainly don't do it!)- just curious about how large financial institutions presumably turn trading profits in light of EMH
I got into Atari 2600 homebrew a few years ago. I haven't made anything playable yet, but the community is my favorite of all time. Even though the community is pretty small, the AtariAge forums[1] are very active. Also, there's a twice-weekly, hours-long live show[2] dedicated to playing 2600 homebrew games, and the developers of the featured games are often in the chat. It's on twitch, which obviously isn't obscure, but the channel itself is.

>Uber definitely over hired in 2016

That's interesting, I interviewed with Uber for an engineering management role in 2016, and was blown away when my potential boss said he had a "hiring target" for next year of close to 100 people. This was a relatively small product offshoot of Uber that is now closed. I thought that was absolutely nuts, not just the magnitude of the number but that getting bodies in seats was a metric that he/I would be measured against, but thought maybe that I just didn't understand how hypergrowth startups work and it would be a good way to gain a new perspective!

Full Disclosure: I did not get an offer, even though I walked out of that interview feeling I had never nailed an interview as much as I had that day.

I'm pretty sure her conclusions are baloney. She admits the main speedreading takeaway: visual understanding is much faster than subvocalized reading.

As for the other statements; of course you can't read complex or deep text by glancing at it and taking it in in one line or paragraph. Imagine trying to learn topology or something that way; you will fail. You have to slow down to the point you're working problems on the side in a notebook. Same thing for learning a new language; looking at the grammar table won't help: I have to internalize it by repetition. Deeply aesthetic poetry; you have to vocalize it, or it doesn't even begin to make sense. Similarly, complex fiction you have to slow down to figure out what is going on, sometimes rereading passages or whole chapters. Sometimes this also needs to be vocalized (Modernist types like Joyce & Pound).

But for stuffing clearly written briefing type texts, speed reading is the absolute shizznizzlenuts. That's why Kennedy found it useful; that's pretty much what the man read all day at work. Low end college coursework also fit into this category of reading material. Lots of business stuff also does. Her neuroscience balognia about saccades may be true to some extent, but you can skip over or infer most simple sentences in the exact same way that Gmail and Outlook completes your sentences via semi-markov models.

Again: it works for simple texts. It also probably works better if you're smarter and a better reader in general, and so taking a bunch of average people and drawing conclusions from their results is pretty useless.
Calling him an "agent" is silly, but Snowden is living in Moscow at the pleasure of the Russian regime. It's hard to believe he's entirely free, or even substantially free, to do what he wants.

It's pretty clear he never wanted to end up there. The US definitely screwed up by leaving him few other options. He's not an agent of Moscow, but he's not a free man either.
I feel like, there are a lot of smart people that are looking for a good idea to start their startup, how do you manage to mitigate that risk?

App is able to access the sim unique identifier.

But I am not sure about website, maybe they have integration with the operators to check last sim change date and compare it to their last know trusted sim or check the last time your phone was audited? You need to generate one time codes in TR banks afaik.

Many of such warts in Unicode are for allowing round-tripping with 8-bit character encodings. I suspect that’s the case here, too. https://en.wikipedia.org/wiki/ISO/IEC_8859-7 has them, too.

That doesn’t explain why Unicode seems to have 27 (!) different “sigma” code points, though (https://en.wikipedia.org/wiki/Sigma#Character_encoding)
> They aren't without problems, but looking at them objectively should dispel any notion that "the government cannot run healthcare efficiently and effectively."

I think that wouldn't dispel the notion that "the government cannot regulate healthcare efficiently and effectively". Unless you expect all hospitals and doctors to be direct employees of the government, you need to look at how they regulate the sector, they won't be running it. I shouldn't have used "running" in my original comment as it implied more direct control than would be the case.
> So for an outsider, I say it's pure speculation.

And you assert this on what basis? There's enough that's been published to get some broad idea of what happens within the firm.

> And I speculate that their outsized gains are due to market manipulation, front running, or other insider activities (as in, illegal/unfair).

If they were engaging in illegal activities, it's very likely the firm, which is undoubtedly scrutinized by regulators, any such activities would have been discovered.

> No one is smart enough; no algorithm or model is future-proof; nobody gets returns like this unless they define the scenarios themselves.

RenTech constantly updates its algorithms. Alpha decay is a well known phenomenon. The firm utilizes sophisticated risk management techniques in order to avoid drawdowns, in all likelihood. Assuming this is the case, they're able to more effectively compound returns while simultaneously levering positions. Here's an example of a risk parity strategy [0], which may help explain how risk management works.

> This is why I don't understand why people take gig jobs.

Sometimes Compared to what? is the most important question.

I've been driving for a few years. Before this I was making minimum wage with no benefits. Before that I had a difficult stretch of unemployment. One of my least favorite questions passengers ask me is What did you do before this? because I don't really like to talk about it. It is a rough job - you take a lot of risk, have a lot of bad days, and you get little reward in return. But at least it's work.

Of course the bottom rungs of the ladder look terrible to people near the top, but for who have fallen off of it the bottom is the most important part. All of these "worker protections" define the bottom of the ladder as exploitation. Let me decide that, my labor is my own to sell for whatever price I can get somebody to pay for it.
Who said it’s a random process? Stock prices don’t go up randomly over the long term.

Joel Greenblatt had 50% yearly returns for a decade.

Also, I don’t think you would expect someone to beat the market every year, but over a ten year period, for example.
Not for me. Volatile is bad as I made more money the years before. End of last year sucked and parts of this year had unusual losses. I prefer trending markets.

I only trade US equities and in particular large caps or soon to be large caps.
> All this despite the mountain of evidence from other countries, showing the greatly reduced total costs and improved life expectancy

Does this account for confounding factors? Such as the US having the highest obesity rates, which has a massive impact on costs and life expectancy.

I'm for universal healthcare, but "X has these results in Y, therefore it'll be the same in Z" is a poor argument and weakens the overall case.
Groupthink in popular tech forums is horrible, if someone experiences an issue, the rest of the people reply "I Dont have that issue", and minimize the person's interaction. Too much absolutism in tech being pushed, you can do the same thing multiple ways, depending on the scenario, people need to think in degrees not binary reactions.

I've been on forums for a few decades, and the interaction has gone to downright militant in responses as fact. I've seen so many truths about tech that simply isnt remotely true, but a big tech company says it, so their fanboi's repeat is as fact.

Common knowledge for an enthusiast vs production is another issue. The proper way of doing something might not be the way an end power user uses it, and their usage scenario can lead to all kinds of issues. So downvoting is way too common to exclude/discredit these people.

I watch them because I feel like I get a better feel for new features, their usage, and their potential, from the way Apple presents them vs reading about them in the news afterwards.

For example, the new ultra wide lens. I know mentally what wide-angle lenses do, but I learned a lot from seeing the kinds of pictures they took, and the comparison between wide/normal/zoom. It was instructive to see how the Camera app uses the vertical letterboxes to show the extra content you would see if you switched to the ultra wide.

I probably will not get the Pro phone, and may keep my Xr for another year. But the ~6 hrs/yr of Apple keynotes are a very information-dense way to consume a year of Apple releases, even despite the fluffier parts and AR game demos.

Your question is like asking why people would ever watch a movie trailer for free - if there's something new that you want to learn about, watching promotional material is a good way to go about it.

Did someone say they were? Seems like the article is arguing against something that no one is promoting and offering solutions that have been available for many years and not yet taken up. Where I live (Norway) electric scooters, hoverboards, etc., are all in use and have been for years but they are typically replacing walking not driving.

I agree with the article that things can suddenly change in unpredictable ways once a new technology becomes massively available. But it seems to me that both of us are pretty much stating the obvious.
Correct, it is insane!! It is "legal" in the sense of "the law didn't specifically plan for this workaround that a particularly greedy company found"

If you think everything is just random, you should educate yourself the impact of superior information sources or technology on producing returns. Are you telling me someone who runs the fastest market data feed between Chicago and New Jersey, doing arbitrages between S&P futures and S&P ETFs is just getting lucky over and over again, and it will eventually be revealed that they just won 30,000 coin tosses in a row?
If Only Bitcoin Existed in the 80s When I Was a Kid in Argentina
Honestly, this is really scary. Personally, I would be unable to take a [2x my bi-weekly salary] hit to my account and that would result in a pretty negative balance. I think I recently saw an article about a bank depositing too much money into an account and the account owner spent it then got arrested. It just seems like the people in charge of how we get/hold our money can screw up with minimal blow back, yet the receiver of the money is almost always the one who draws the short straw. I could be wrong, but it really makes me question the safety of (what little) money I have.

>Also the UP is pretty much miserable.

I feel that is subjective. I know many people in this area who live wonderful happy lives being self sufficient, living off the land and having a large community and frequent family gatherings. The area is beautiful if you like outdoor activities such as hiking, camping, fishing, bike trails and in the winter there is a lot of cross country skiing and snowmobiling. Worst thing here right now is the Opioid crises which sadly is happening in many rural areas across the nation.

I guess personally I would prefer the country life vs fast living in a big city, but again that's my opinion. Especially with the ability to work remote, and the ability to get things shipped up here via the internet it makes life easy.

Gone are the days of having to drive 3 hours for computer parts :)
> In 1998, two independent teams of astronomers discovered that the expansion of the Universe is accelerating, consistent with the presence of a uniform contribution of Dark Energy. It was not recognized, however, that GEODEs could contribute in this way. With the corrected formalism, Croker and Weiner showed that if a fraction of the oldest stars collapsed into GEODEs, instead of black holes, their averaged contribution today would naturally produce the required uniform Dark Energy.

Hmmm, if this is true, then it means it's possible (in principle) to engineer the expansion rate of the universe by either preventing or causing the collapse of stars in a certain way. See the concept of Star Lifting: https://en.wikipedia.org/wiki/Star_lifting

Feeding 11 billion people where a large portion of those people can only afford to spend $2/day on food? Very difficult.
