If deflation didn't cause unemployment and the great depression, why did the collapse of the bubble lead to unemployment and the great depression?

Hard money prevents the Fed from changing the inflation rate but it doesn't prevent random and severe changes in inflation and deflation.

From 2010 to 2013 bitcoin had a deflation rate of 96%. Which is insane any normal economy would turn Mad Max if it had that type of deflation. If I had received a loan for my house for 100k in 2010 I would have had to repay $1.5 BILLION in 2013.

Then from 2013 to 2014 it had an inflation rate 353%. If inflation leads to bubbles and we all used bitcoin this inflation would led to the mother of all bubbles.
The Value of Values (Rich Hickey)
There are a number of studies testing this, and the consensus that emerges from meta-analysis is that women tend to be liked, or respected, but rarely both. Cuddy (2005) is the citation I've memorized for this.

In contrast, men have no problem being liked and respected in positions of power. Women managers tend to be viewed as nurturing pushovers or bitches.

It would indeed be simpler if liking decreased as social distance increased, but the world is not always so simple, and a thousand years of gender stereotypes and oppression don't end in a century.
I think what you're saying is, in essence, IEX's current incarnation of handling stock transactions does not exist in a vacuum -- because they are only a trading technology platform instead of an exchange like NYSE & NASDAQ. As a technology platform, they are really just "clients" of other exchanges and therefore, they're the tail trying to wag the dog.

If they become a full-fledged exchange with stocks listings exclusive to IEX, then those stocks would have better "fairness" characteristics that Brad Katsuyama claims.

Therefore trading AAPL through IEX may incur a financial penalty for being on the "slow" IEX system but trading YC2019Unicorn stock exclusive to IEX may not.

I don't think the presented axes are correct (#3 I'd argue isn't necessary, though there may be a different supply factor that is, and #4 itself is equivalent to being a currently lucrative profession, it isn't a separate consideration that is necessary), and programming certainly currently meets 4, and arguably meets 2, at least for some significant subfields of programming.
> Take his Ubuntu example - for what percentage of users does the fact that it doesn't fit on an actual CD really matter any more?

That's only one thing among many mentioned, to prove a point.

The fact that it doesn't run well with only 2GB of RAM certainly affects plenty of actual and potential users. So the point stands. Not about the CD per se, but some optimizations are general and apply everywhere.

And every single Ubuntu user has complained at one point that pressing the Win/Super key does not bring the menu fast enough, or that the search results are not fast enough.

So, there's bloat.
> They could see my order at BATS, race me to the next exchange, and cancel all their sell orders and buy whatever is left, buy everything up, then turn around and try and sell stock back to me at a higher price. So that was the game.

This is the heart of the problem with IEX's explanation of the markets, and why I think most people view HFT as unfair. But its not how cross exchange market making actually works. The HFTs are not rushing to buy up existing inventory from others who are selling it, in an attempt to screw others. They are the ones who are originally offering to sell it in the first place. They aren't rushing to buy, they are rushing to change the price of their inventory.

The metaphor I like to use is that of a chain of gas stations running down a highway, owned by the same people. If a tanker truck pulls up at the first two and buys up all their gasoline, it would be perfectly reasonable for those first 2 to call ahead to the rest down the highway and tell them to raise their prices, as they clearly were being used to supply someone else's industry at lower prices than they should.

That phone call is what IEX prevents, so that their customers (guys with big tanker trucks) can buy gas without impacting the price of gasoline.

Whose money do I think is in those hedge funds? I don't know, a whole bunch of millionaires?

If the direction you're heading is "modern trading is scalping profits from pension funds and mom-and-pop mutual fund retirement plans", you'd probably want to be prepared to refute Vanguard's chief investment officer, who says HFT has in general improved outcomes for one of the world's largest and most trustworthy fund managers.

muddling the issue. At least in Chicago, drivers are already required to have insurance. Why do they need to have special additional insurance if they are Uber drivers? But, again, in Chicago, the city and state worked this out with Uber and came to a compromise.
But if you're plugging in input like that, couldn't the malicious user just pass in something like

&& sudo rm -rf /

anyway? Which would render the whole point of the article moot.
But if someone, somehow, developed a legal technical means to eavesdrop on the order you sent to your broker, and traded based on that, wouldn't it be fair to say that this is, in some sense, similar to front running? That is what the article is claiming, although the information is the information available at one exchange before it reaches another.

And going on with this analogy, wouldn't it be the case that we would want to prevent this eavesdropping if possible, because it has a similar effect to actual frontrunning, namely that the intermediary captures the information rents associated with your knowledge of the order you are about to submit.
It's a question I've seen pop up every now and then. If you look at the current distribution landscape in any given enterprise today you'll probably see a standardization on one distribution, with a few exceptions here and there. This is mostly due to the need to have ease of management and the same goes for container OSes. If you mix several of them you're adding on "management tax" for the underlying OSes, even if the containers might be managed by a tool on top of it.
Deploying/configuring/managing CoreOS is different than RancherOS which is different than SmartOS, for instance.

I say try a few of them, including the tooling that comes with them, and since the containers look the same and will behave the same on all of them you can easily change your underlying OS (and tooling) in this testing phase. Then try the different tools that can be used on top of them and I'm sure you'll find a mix that works for you :)
Right, why write

'{ "foo": "bar" }'

when you could write

JSON.stringify({ foo: "bar" })

and get a static guarantee of valid JSON?
ok, but we don't really know for sure what is good in the long run. That would require perfect foresight about the long run.

Actually, what I'm saying is the following. Don't put resting orders out onto IEX - a big player will take your liquidity in a big trade and you'll suffer the inevitable price impact. I.e., putting your orders on IEX rather than the open market is just a way to funnel your money to JP Morgan.

It's far better to mingle your orders with HFT orders - that'll keep the big guys honest. You'll probably also pay lower fees.
I noticed a huge difference with this site: http://www.2ality.com/2015/02/es6-classes-final.html

In the previous Firefox version scrolling on that site was laggy to the point of being unusuable for some reason.
The problem is that front running requires 2 things:

- the ability to see orders ahead of someone, which this article implies you can, but you can't.
- the fiduciary duty not to use someone's intent to trade against them.

HFT traders do not fall into either camp. They can't see your order before it goes to an exchange and they don't have a duty not to change their prices on one exchange in reaction to price moves on other exchanges.
> One of the main complaints of cross platform GUI's has been that they don't work like native applications.

wxWidgets applications work like native applications because they are in fact using the native toolkits, and some successful applications, like Audacity, are written using wxWidgets.

And it runs fast, as it is C++, as expected. Why it is not used more fits perfectly with the content of this article.
Modern market makers are very good at pricing a small spread to uninformed flow while making informed traders pay.

My understanding was that it's mostly the opposite, that MMs profit from uninformed order flow (so much so that they'll buy access to it from brokerages), and that informed traders were their predators in the market food chain.

At any rate: cost of trading has by every account I can find plummeted since the introduction of automatic trading. As recently as the 1990s, spreads were quoted in eighths of dollars, and there was widespread collusion to fix prices at quarters. In 70s and before, the markets were worse; basically organized fleecing operations.
> How might they have "capitalized on" their "homogeneous group of nerds" that wouldn't have caused them to just leave?

The possibilities should be endless. One thing I could have imagined would be cooperations with companies that have products which reddit user value and use heavily. Take Valve's Steam, for instance. Reddit could have offered those companies a service to buy a sub that is especially tailored for the company's needs so that they could turn their sub into a tailor-made r&d lab (with special features as required...). Those who love their products would be thrilled to develop ideas and share their user knowledge with their favorite company.

As long as they would've selected companies carefully and resist from interfering with other parts of reddit no one would run away. If anything, those "special sub" could be a gateway drug for new users.
Whatever the realities of the market, people have an expectation of "fairness", and are generally against the idea of a party or parties being able to insert themselves into a situation where they can essentially get a speed jump over the rest of the market by virtue of buying a place that enables this (microwave links, colo in the exchange etc.)
Interesting ideas, thanks for the response.
Ahh, someone might just have added it to troll me, or I'm crazy.

Existing drivers can want what they please. That doesn't obligate anyone to give it to them. Blockbuster and Tower Records wanted a lot of things too.
Insurance argument is a red herring because people who drive cars are already required to have insurance, irrespective of Uber. We are talking about some special form of insurance on top of that. Uber can actually either self insure drivers or get very very cheap insurance for them because they know who the good drivers are.
Why would a HFT maintain a huge inventory of stocks? If you make money on the ability to execute trades faster than others on the movement of stocks, you're losing money by holding them. It feels akin to a car maker holding an overlarge inventory of parts - it's just tied up capital that's not making you money. In HFT, don't you maximize the profit by holding as few stocks for a little is possible?
Regarding the pay, I'm a bit worried that it might not be the case in UK. For example, when working in Big Data positions (my current area), it's not hard to get 100k pounds per year or more, while I ads for scientific or graphic programmer (or anything non-enterprise for that matter) rarely exceed even 50k. The difference is that on 100k I can retire before 40 and on 50k I'll probably work forever... If that's indeed the situation I'll probably try getting into the US as H1-B as I hope the situation should be better there.

As for getting a self project - I'm thinking of doing a physics engine focused on static forces - something inspired by structure engineering methods (solving with finite element analysis for example). I have no idea if I can make things bend or break believably in real time but it seems like a cool idea to pursue.
Everybody wants to trade with no price impact. If you asked me if anyone else should be allowed to colocate their servers, I'd say no, just give me a monopoly please. One participant's desires don't make a good market.

Fair and non-discriminatory access to exchanges (not free, but anybody can pay to compete if they wish), fast trading engines and deep order book information are what let traders put up such tight spreads for customers in the first place. Vigorous competition between all market participants keeps prices fair.

Thanks HN for giving me good content! I maintain a list of these and they come up sufficiently often enough that I always have something to watch when I have to cook.
Cute. Except the ones suffering the most from the HFT machinations were most likely pension and mutual funds, the ones most folks parents rely on. Not rich fucks or their catered hedge funds.

The problem with EV is that getting one doesn't prevent other CAs from issuing illegitimate (non-EV) certificates for the same domain.

I'd be much more willing to pay for EV if that somehow could simultaneously make it technically impossible for parallel certs to be issued. That would provide actual value. But not when all you are paying for is just a bitflag that causes browser chrome to change slightly.

Vanguard says exactly the opposite is true. Which makes sense: passively managed funds and funds with simple value-based investment parameters don't trade aggressively. On the infrequent occasions when they do trade, they benefit from the reduced cost of trading.

If you have your retirement fund parked in an actively-managed fund where you pay an annual fee to have someone who makes $500,000/yr base continuously push "buy" and "sell" buttons on their computer screen all day, you have bigger problems than HFT.
Pick up the phone and start calling people. Sell them your service. You get a lot of rejections to start with, but that's how you learn what to say to get further. Eventually you'll start to get positives.

The language is more restrictive and sometimes it's harder to get something working. Of course the payoff is immense, you end up with much more maintainable and composable code. However I'm not convinced that many enterprises care much about these properties, as they are often more of a long term win. People also have an emotional attachment to their existing tools and paradigms.
Ask HN: My mom is lonely and sick. What can she do to pass the time?
Hi HN, throwaway here for privacy reasons.

My mom is ill. At home is my father who she hasn't exactly bonded with in 25 years, my sister who is about to go off to college, and my brother who is otherwise useless.

My mom loves to talk on the phone, smoke her cigarettes, and take her pain pills (don't get me started). She is very likeable but she's a suburban woman whose friends are all working during the day, and then in the evening they're at home with their families.

She is an incredibly, incredibly intelligent woman, with a brain unlike any other. She worked for the government before she became a housewife and stay-at-home mom. She hasn't worked in 22 years, but when she did, she was making six-figures (and earning it, despite the mostly-valid government job jokes.)

She isn't tech savvy but she's capable of looking up recipes, manipulating the Google, answering emails, stuff like that.

What is something I can put in front of her to stimulate her?

I thought about something like MTurk, but the idea of her time being worth pennies will only turn her off.

Thanks :)
It is not a scare resource. It is simply, like with wine or art, viewed as valuable by those who have decided that they want it and don't want the easily available alternatives. [1]

If you can't get ycombinator.com you can get yycombinator.net or ycombinator.somenewtld (that was just released).

And Wine and Art of the type that has value can't be created in as large a quantity as there is a market for anyway (cheaper mass produced wine can of course). If there wasn't scarcity the value would not be as great. With domains the reason the value is high is similar. There is only one "bell.com" and if you want that name and not "thebell.com" or bell.xyz you need to pay the person who got to it first (legitimately I might add).

This is all just sour grapes. Somebody wakes up one morning and decides that life isn't fair because the domain that they want is owned by someone else. Might even be a bakery on main street that got to "mycakes.com" first (made that up ..)

> "Real estate, on the other hand, is a very similar case, and in my opinion there should be laws against playing dog in the manger with real estate - either an outright ban or a hefty penalty in the form of extra property tax."

Ridiculous free market system works like this and always has. You are free today to buy real estate at absolute bargain prices in Newark NJ and sit on it for years and try to make some money later. Go a short distance north and you will end up in Manhattan where you won't buy a parking space for the same 4x price. What do you want to do now have the state take all property that people have acquired legitimately and redistribute it? Ridiculous.

[1] And maybe when someone decides to name their company they should consider what names they can buy prior to deciding to use a domain that they will not be able to buy, and then crying about how unfair the system is because it is not available right?

The purpose of laws against frontrunning is to enable you to have a trusted relationship with your broker. There is no benefit to creating a trusted relationship with your adversaries.

Similarly, doctor/patient confidentiality laws are there to created a trusted relationship and make you comfortable admitting to your doctor that you had unprotected sex with lots of heroin addicted hookers in sub saharan Africa and you now need all the STD tests. In contrast, passing laws against journalists reporting on who visits hookers has no such benefit.

The article doesn't touch at all on the performance of lodash compared to underscore or even native functions. In many cases it is more performant. So while you do have to decide if the extra library load is balance by the better performance in your specific use case, it should be considered.

Also, there is the simple fact a lot of people like the abstraction compared to the native solution - it is often simpler to use and remember.
The short answer is that they have to. Resting orders from yesterday are always faster than microsecond orders from right now.

So a market maker that was super fast but didn't rest orders, would be competing with one that is as fast as them and willing to rest orders. So, the resting order ones win and drive out the non-resting order ones.

Interesting data, poor presentation.

The tables need some formatting and colors would be nice, too. Instead of "slower" and "faster" it should be just a factor. So, 2x would mean that it takes twice as long and 0.5x would mean that it's twice as fast.

Also, what's the baseline? Where does that 1x come from?
As far as I understand, reddit did introduce a new search function yesterday, which pissed off mods of several subreddits. [1] Additionally they fired(?) an employee who acted as a interface between the r/IAmA mods and the people who do amAs [2], who are usually not redditors. So the mods of r/IamA set there sub to private. That means that only invited users can see the sub. From there quite a few other mods did declare their frustration with reddits communication, their solidarity with either the IAmA mods or Victoria and various other grievances. And either set their subs to private or at least declared their solidarity. And by now half of reddit is private and the other half rages agains the admins. ( Reddits front page, that is the ~20 highest upvoted posts on the site, are uniformly against reddit.) For a bit more details see [3].

They may scalp profits from hedge funds that trade actively, but guess what, they're playing the same game: trying to trade at attractive prices. With two pros competing with one another, why does one side deserve sympathy? I don't see Burger King whining to the press when McDonalds outearns them.

For the average passive indexer who buys some ETFs or mutual funds every quarter it's meaningless at worst, and probably a net benefit since these products have tighter prices now.
