The comment you are responding to addresses the claim that the 737 max is not passively stable. It is less safe than other aircraft, but not because it requires active control for stable flight in any manner comparable to a fighter jet.

I'll direct you to some portions of my other comments that you seem to have overlooked:

> airlines and pilots were not informed well enough about MCAS

> previous auto trim systems could also be "out muscled" just by pulling back on the yoke without actually switching on the manual override.

> polluting this thread with lies

I'm pretty sure everything I've posted on this thread is either true or obviously an opinion. If some things are not true, please point them out specifically so that I can correct them.

Nowhere have I said that the lion air 610 accident only happened because of poor maintenance or pilots actions, but it is undeniably true that with different pilot actions and aircraft maintenance the accident would not have occurred.
Presumably, the greater the time period between auctions, the more risk there is for market makers, and therefore the greater cost to customers. I'm sure there's a sweet spot that is less than once per day, and greater than continuous. But perhaps determining that sweet spot isn't worth the added complexity, and letting them fight amongst each other over speed is just better for everyone.
When I lived in Seattle, it blew my mind that your society had second-class citizens driving around, cutting lawns and blowing leaves. It seemed so absurd to me, but sense to a lot of people, and was legit a mainstream thing.

Noise pollution in cities is an insidious problem. I'm happy to see that DC managed to reduce it somewhat. Although, 3 more years to wait is a bit of a kicker.

> In short, when you send an order from your computer to buy say 10000 stocks, this order gets split to all the multiple exchanges. When the order hits the first (closest) exchange, HF Traders will pick that up and race you to the rest of the exchanges and try to front run you by buying the stock in lower price if available and make an offer to your bid price that they know is coming.

1. This is not 'front running', this is just other parties reacting to and executing on public market data before you. The term 'front running' is understood to mean something specific, and different.

2. Orders don't get split across multiple venues by accident. It's a conscious decision. Anyone who chooses to route multiple orders to different venues in a way that causes an information imbalance (ie, so the orders hit the venues at different times) is going to get their lunch eaten by the rest of the market. Only idiots do this - the rest of the world times their orders taking transmission latency into account.

It sounds like we agree.

To be clear, I think that free will--by definition--cannot exist in a purely deterministic universe. Any semblance of free will in such a universe would be purely illusory. It also cannot exist in a universe where events can only ever be some combination of random events and determined events. Randomness is also not free will.

Free Will would have to be some other special category of events that is neither determined not random. We don't have a word or phrase to describe what these events would be like other than "Free Will." However, lacking the vocabulary and math to describe it does not make it non-existent.
Plastic is a great material for some uses, but it’s also a very durable material. I’d love to purchase shampoo in the form of a refill of the plastic shampoo bottle I’ve already purchased some months ago. Why buy a new bottle every time? That’s the part which doesn’t make sense.
You're comparing SF to rural America. They're of course quite different.

But OP is asking about other major cities like Atlanta, Boston, Chicago etc. If you think those are anti immigrant racist homophobic etc hellholes, you might be stereotyping quite a bit yourself :)
HFT contributes to making the market. Making the market contributes to liquidity and the ability to get in and out of things quickly without taking major hits. This seems abstract until you think of cases other than stocks where you desperately rely on a market --

1. Think homes. Consider buying/selling a house and how painful it is to keep something on the market hoping to find a seller (often at a hit if you want to unload quickly.) Or a buyer desiring to purchase something only to have a handful of homes come on the market.

2. Imagine if for every book you read, you could quickly unload the book (or buy new ones) without fire-selling and paying an absurd shipping cost. HFT and market making reduce friction. They are market lubricants.

3. Imagine looking for an apartment to rent and there were a perfect curve of apartments a dollar apart available all the time!
If the bone has more calcium per unit volume, it should contain more strontium-90 per unit volume as well - meaning these people should have a slightly higher inherent level of radioactivity than the general population. If so, this should be measurable with medical-use radiation detectors.
I don't agree. From what I've seen:

* most people will move somewhere because of a job, not because of the weather

* most people don't want even want to move to another city in the first place.
It’s really quite simple; Silicon Valley is maybe the one place in which I have ever found nearly everyone I meet has a “pay it forward” attitude. It is infectious, and it means that as a “no name” startup founder, you have nearly infinite access to advice and capital, as long as you are convincing enough and tell a good story. There is no immediate expectation of return. I spent most of my life living in NYC, and I originally started Tinfoil in Boston (and went to school at MIT). Both cities are “startup hubs,” but the same attitude doesn’t exist. Boston was particularly bad about “what’s in it for me?” being the common theme of any conversation.

The upshot is that now I volunteer my time often, and for free, to help others who are just starting out. I cannot predict who will be the next Google, but I enjoy helping smart founders, and I enjoy giving back in the same way I was given to.

The article explains what the article means by political correctness.

The survey question reported in the so-called "Hidden Tribes" report, from which the article derives its statistics, does not explain what is meant by 'political correctness'. It means whatever the respondent thinks it means.
I’ve never purchased a car new, and my previous daily driver was a 2003 that was damaged in a minor collision last year.

With every car I’ve owned, I have no direct relationship with the OEM. I think I had a Cadillac repaired by the dealer once because it ended up being cheaper. That’s a feature. I’ve seen what happens when companies corner the market on anything — it’s not good for anyone but the company abusing the market.

I’d lease a Tesla. Anything else is too big a risk.

I've had a few casual conversations about the collapse of California recently. In my opinion, zoning laws will be the death of San Francisco. The greed of the NIMBY's will eventually drive prices too high for anyone that didn't buy 20 years prior (i'm amazed it hasn't happened already). I've been entertaining the idea of a state putting extreme limits on zoning laws. I'm not an economic expert so i'm not sure what it would look like, but I can't help but compare to Tokyo with their ballooning population and stable cost of living.

You don't get any benefit from putting your trading system half way between the two exchanges, you colocate it with one or the other (or both). Likewise if there are three exchanges to trade on, you don't build a datacentre at the circumcentre of the triangle or whatever voodoo geometry nonsense. You colocate at each of the three and buy/rent/build a line for each of the three point-to-point connections. Source: worked in HFT for more than 15 minutes.
>From what I understand, this does not seem to be the case.

Maybe. Determinism isn't dead, by any means. Depending on what model of quantum mechanics turns out to actually be correct, full determinism might be just fine. But even if one of the models that would invalidate full on determinism is correct, 'adequate determinism', similar to what Stephen Hawking believed in, might apply - the idea that the level any quantum fluctuations occur at makes it unlikely to result in any difference at the level that human thought, etc., operates at.

iMessage is popular, but that has less to do with anything Apple has done and more to do with how badly Google has failed with a messaging strategy. iMessage is popular because it works ok-enough, is the default, and is consistent. Would you really rather have the Android situation, where you need SMS and umpteen other third-party messaging apps, including whichever 3 google is pushing this month?
I guess I’ve worked on to many apps that resulted from this sort of thing, over the course of years. In reality, everyone gets a voice and every opinion matters devolves to the vocal minority doing what they want, damn the consequences. Similar to online discussion forums really. It’s almost tautological that this vocal minority does NOT have the best interest of the product or company in mind, but only their own self aggrandizement and careerism.

Somebody at the top ought to have a vision and ability to work with feedback from real customers with real needs to deliver a product that users love and continue to pay for.

Don't worry! We are all busy and sometimes is normal to read too quickly a message on internet.

My advice would be to have one single broker no matter what, so don't replace the websockets server with another instace of mosquitto, but just use the same old instance.

Then, the ice thing of working with a protocol is that you don't care of the implementation, hence just keep using mosquitto until it support the load and the, eventually swap verneMQ if necessary.

Be careful with your custom authentication logic, that if you want to migrate will require you to port it over.

Verne provide plugins for Auth so it is not an huge deal but you need to think a little bit ahead.

But again, if mosquitto is working fine just keep it!

Cheers!
> How can you possibly say HFT is neutral when it's been responsible for multiple flash crashes that hurt the average investor?

The average investor holds onto stocks for months to years. A flash crash may last minutes, before the price is back where it was. How does a flash crash hurt the average investor?

> Not to mention the practice of front-running and other shady practices that HFT's use to make profit.

Front running is where a broker or other agent trades on private information given to them by their client: the broker receives a big buy order from their client and then buys the market up on their own account before executing the client order and making a massive profit. This is illegal.

HFTs can't front run - they only have the same public information at the same time as everyone else. The fact they can execute on that faster than others hardly seems 'shady'.

Yes, this annoys me.

Yes to use their service I need to send them text, they can't process it if I don't although it would be nice if they offered an offline app, even at a price.

However it's annoying how they store documents and try to be a document management / basic authoring system to, I see no reason why they should need to store documents.

It also seems they are missing a trick. If Grammarly opened up their API's, there are so many integrations that people can freely write and drive more paying Grammarly customers. At the moment I copy and paste from my text editor into Grammarly and back out! I never installed the browser extension for the same reasons the originally twitter poster mentioned, i selectively copy and paste in to the app.

> it isn't that Theranos was particularly notable

Yes, actually, it was.

The primary issue is that Silicon Valley runs on "Fake It Until You Make It" very strongly. That's not a real big deal when you are delivering dog food or hooking up hipsters for sex--the money simply goes down the drain and that's life.

Once you start the path toward something that has real consequence--diagnosing medical issues or piloting a 2 ton death machine without a human--you've jumped a VERY important line. "Fake It Until You Make It" isn't good enough--engineering now matters and people can get badly hurt. The standard goes up and you had better pay attention.

The secondary issue was the nature of Holmes privilege. She had no qualifications to do what she was doing and still managed to pull in a whopping amount of funding from very connected people without oversight--not necessarily an issue in and unto itself. However, when things were going badly, she didn't fess up--she pressed forward by lying about it and then intimidated (possibly criminally) those who attempted to expose it. That's crossing the line.

And, to be fair, I find the "scientists" who were Theranos' mouthpieces through this to be far more guilty and wish their names were being promulgated much more strongly so that they can suffer the appropriate censure for aiding and abetting her.
When someone writes something on a piece of paper, puts that piece of paper in a box, and later I see someone reopens that piece of paper then I can be reasonably confident I see whatever the original person wrote on the piece of paper.

I have no such confidence in electronic messages. Unless they're plaintext.
> Take out the intelligence and skill, and you get Anna Delvey and Holmes.

You still need to add mendacity.

If Musk, Gates etc. had been less lucky, would they have turned to lie to try and manufacture luck? They probably did a little bit -- would they do it at a criminal level?

Some might have; it's a thing that some people do. But it is unfair on them to assume that they would have.
Flash Boys is terrible (it's not even good as a book --- and I'm an avid fan of Michael Lewis's). It's embarrassingly bad on the technical details.

I like "Flash Boys: Not So Fast" as a corrective.

A much better book, from another HFT skeptic, is "Dark Pools".

The example you provide (of basic, naive latency arbitrage) matters for trading desks at giant investment banks. They make their money in part by selling execution services to giant holders of stock. Major trades by these people (big "blocks" being "shopped") are tradable market news. The giant holders of stock would prefer it if the news didn't get out until after their orders were filled. That's a service people like Katsuyama used to be able to offer his wealthy clients with very little effort on his part. That service has since been automated away, and it bothers him. I guess I'd be bothered too, but I'm not sure why it's moral dilemma.

Front running isn't a technical problem and it has little to do with how fast traders are. It's an agency problem: a broker "front-runs" their client when they receive an order from that client and make proprietary trades against and ahead of it. Random people in the markets don't have an agency relationship with other traders and are under no obligation to avoid competing with them.

The EU have committed to Ireland, and the Irish government themselves have committed that there wouldn’t be a hard border. The U.K. government has also committed not to build one. It’s not just the U.K. that has committed not to build one - it’s all parties involved in this that have committed not to build one.

In addition, there are other borders between EU and non-EU countries that don’t require immigration controls. It’s hard to see why one is necessary - other than if the EU was deliberately setting out to make leaving look as difficult as possible.

OP was talking about major metro areas and the cities I mentioned are major metros with all the pros and cons that implies.

At any rate, you should really try exploring and getting outside of the Silicon Valley bubble if you think the rest of the U.S. is just a bunch of racists ready to shout offensive things to you.

Even in rural areas in Texas and Florida, big portions of the population are Hispanic. It's not unusual at all. In many Texas honky tonks, you'll find quite a few Hispanics. Some of the top rodeo stars are Mexican and Brazilian. In fact, most of Southwestern culture, from cuisine to music to dance to fashion, is a blend of cultural elements from Mexican, German, Czech, and Pole immigrants.
Have you ever been somewhere where the water coming from the tap isn’t clean enough to drink? It’s very dangerous, even if you drink bottled water. When we used visit family in Bangladesh in the 1990s, we’d bring along a ton of Evian. Not only would we drink it, but the kids would take sponge baths with it, because you definitely should not shower in water you wouldn’t drink. But every time one of the kids would still get sick, because it’s hard to avoid: washing your hands in tap water, eating from dishes washed in tap water, eating fruits or vegetables rinsed in tap water, etc.

The only household uses you could use a lower grade of tap water for would be toilets and clothes washing (and then only if you run the clothes on a hot cycle).

Heh funny, I did Chicago first as well and now I'm doing SF. It was also really cool for me to be in Chicago and discover my first tech scene, now SF is a thousand times crazier.

I agree with GP, although I really want to like SF but it is hard because I've lived in nicer cities.

We've contemplated moving to NYC in the beginning, or after SF if we really don't like it, but I don't see myself living in NYC. It feels like a great big city, without the advantages of the great big cities you have in Europe or Asia.
