If I run a bakery and you run, say, the Mint...

Ten years ago, I bake a loaf of bread, and sell it for a dollar. Then I invent an amazing machine that can produce the same bread more cheaply. I'm about to drop my bread prices, but you mint some new coins and add them into circulation. So I keep the price at a dollar per loaf.

I scrutinize my bread supply chain to the last detail. I optimize the flour, I optimize the temperature. I fire all the workers and replace them with machines. I'm saving every penny I can. Loaves get made faster! Loaves get made cheaper! Bread is flying off the conveyor belt!

You pull a lever and crank up the printing press. Dollars are being added in the millions, in the billions!

The price of bread stays at a dollar; has the currency been debased? I honestly don't know.

Few people if any ever seriously alleged that Russian hackers intervened in the administration of the 2016 US federal election. Rather, the assertion was that Russian agents spread disinformation on media platforms, and that was found to be largely true.

Dishonest claims about the legitimacy of the 2020 US federal election are a lot more dangerous, as is obvious from the Jan. 6th terrorist attack on the US Capitol.

"hedge fund" doesn't really mean hedging. It is just a fancy (high fee) name for "actively managed" that usually uses more exotic strategies than buy and sell based on earnings reports.
Yes, but that doesn't explain how to fix it. The signal is clipping (slight distinction from too much gain, because too much gain causes clipping) if you notice, one note is mostly clear, but the more notes played, the worse it sounds. He’s adding all the tones together, and not re-normalizing them before his addition. Which i suppose could be thought of as “not adjusting individual gain down” before adding signals together. Also filtering really would work wonders if he's just generating pure tones (sine waves).

> Significantly increasing those capital requirements by requiring pre-funding of all trades without the benefit of recognizing the offsetting trades would substantially increase the costs of trade execution to the end user.

I don't see how this follows, if the trades are settled faster? Wouldn't you have to keep less capital on hand at any given time if you're settling trades faster? I'm clearly missing something, not sure what.

It's probably more that capital has become more and more abundant relative to need for capital (whether through wealth accumulation or more advanced financial infrastructure), so of course it has become cheaper and cheaper.
If you're using an AI, I assume they see that the comments coming in all follow an extremely similar format or come from suspicious IP addresses or come in at suspicious time intervals and so on. There are plenty of indicators that a review might be a bot.

That would be wrong but believable. I read some of the reviews, they did look very similar in ways beyond describing the same problems.

But I'm good with assuming malice, it seems like every company that takes action right now is unlikely to be doing it coincidentally. Maybe Google is doing it because of money somehow, hopefully it's an actual mistake that they'll fix. I suspect the former.
This whole story feels like a turning point.
There's the opposite. If it doesn't disable suspend, it is not a work computer.

my work macbook will close all the network connections/compile/rendering when i close the lid to walk from meeting to meeting (or used to. seems like the universe closed this bug as 'WONT FIX')

I have no decent UX to disable that when i need my network connections/compile time/render time/etc... It's either sleep enabled and i can't risk touching the lid, or complicated arcane steps to break sleep and allow me to carry it.

I can understand complaining about getting thrown out of a casino for winning too much. I can't understand complaining about getting thrown out for losing too much. The people "investing" in these companies are totally clueless and the majority of them are going to lose all their money. Cutting them off is clearly in their best interest.

Whether or not that kind of paternalism is acceptable is another matter.
Let me rephrase your argument, so its tractable.

The risks are overblown, and so its ok to create places with decentralized freer speech.

Firstly- I removed the parts where you stated that this is like the phone network.

Phone calls are temporally limited, once you are done with a call its over. You can't hear that voice again, or relive that conversation, except through memory.

Text on a forum combines the worst of phone calls and books.

Not only is it easy to create and respond in real time (Like a phone, and unlike books or letters), but it is also persistent so people can read and participate in that moment of emotion repeatedly (like a phone call).

These are great and greatly bad depending on how they are used, but they are dramatically different from the way a phone call impacts human beings.

Which brings us to the second point - it isn't only the information, it is the emotion, or in combination the "content" of speech on forums/social media that matters.

Having actively tried to push for free speech and then managed speech, I can guarantee that without moderation, forums/social spaces collapse. They fall victim to our neurology, and the scale of people on it.

So you can't avoid the use of force here, the question is the amount of force being used, and whether it is commensurate to the specific event it is being used to mitigate.

How many Dodo birds can a dollar buy today?

A better question might be, how much would you have volunteered to pay twenty years ago for the functionality an iPhone gets you today? In 2001, if today's iPhone were being sold, what price would have made it a successful product among average consumers? (Not, say, the military or super-wealthy).

I think... Less than $10,000 for certain, less than $5,000 most likely. In that sense the price has certainly come down, but semiconductors and electronics has obviously gone through rapid technological scaling and deflation is expected in that sector.
> Let's put it this way: each shenanigan that Wall Street pulls like this means at least a few thousand people who will rather buy fucking $DOGE and UNI tokens instead of trusting these institutions. The shift is happening and is inevitable, it's just a matter of how fast we will be able to build it.

Why is it that when wall street pulls something, and has mechanisms to keep them accountable that will ideally be executed (there's a ton of lawsuits) it drives people to crypto. But when crypto does something shady you just say "ah ha decentralization works!! Satoshi will deliver, we just have to wait!!"

Nobody would "rather own $DOGE" lol, the wsb nihilists are pumping it like they pumped $GME. They're currently organizing to do the same with silver. And various other heavily shorted stocks like Dillards. They care exactly as much about $GME as they do about $DOGE. The goal is tendies on the moon. Not to own a ton of GameStop shares lol, and certainly not to own a ton of meme-based cryptocurrency with a dogs face on it.

Unlike the crypto maximalists, the wsb folks have the goal of making a bunch of money, and see the market they're operating in as a means to an end. Not some dog-themed revolution in money or assets.

For you, cryptocurrency is your world. It's a religion. It can do no wrong.

For the WSB crew, they're in it for the lulz, the memes, to get rich fast, to screw over their opponents (Melvin) and get their wife's boyfriend off their back. Most of these folks dont even own GameStop, they own GameStop derivatives they plan to settle in cash.

Is there proof Melvin actually got out? All I saw was a “source” on CNBC.

EDIT: This is the story: https://www.cnbc.com/video/2021/01/27/melvin-capital-sells-o...

It's full of plausible deniability phrases like "from what I understand" and it's very much a game of telephone. They could easily say "when I meant we were out of the stock, I meant that we had covered some of our positions" or similar.

I can't find a non-hearsay source anywhere, neither written nor in the form of a recorded interview.

> Mass death

Covid has killed a lot of people and created a lot of heart-break, and it would be heartless to try and minimise that or to view it in purely economic times in this moment.

However, I think that in 100 years, future historians will describe the effect of the deaths itself as being pretty negligable: maybe 10% over the expected rate without Covid in 2020 and 2021, maybe 5m people in each year total, against an expected death rate of 50-60m. Many of these deaths were people outside of the primary workforce, unlike say WW2 which killed off many of the young able-bodied men the mid 1900s economies primarily relied on.

I guess all I'm really trying to say is that when the story of Covid is written in 100 years time, "mass death" probably won't get much of a look-in vs economical and mental-health costs of lockdown, disruption to business, and so on.

That user took a strong position in GME before this all went down, and is still holding.
No. I never said that Google taking the reviews down is warranted or they are in the right or something. I'm just saying I don't think it's a malicious attack on users. And app store reviews of a stock trading app and the consensus of the general public on their police are completely different social scenarios, so comparing them is aimless.

> We’ve printed trillions of dollars and Congress is en route to print trillions more.

First off: it's not Congress that controls the money supply, it's the Fed. They're independent.

> The price for that has yet to be paid.

What price is that? Inflation? Japan's M2 has risen a lot, and it hasn't seen any for decades:

* https://fred.stlouisfed.org/series/MYAGM2JPM189S

* https://fred.stlouisfed.org/series/FPCPITOTLZGJPN

Japan's interest rate has been below 1% since April 1995:

* https://fred.stlouisfed.org/series/INTDSRJPM193N

From 2002 to 2006 it was 0.1%.

The equation for inflation is: M x V = P x Q

Everyone talks about "printing money" (money supply: M) with the Fed, but no one seems to pay attention to velocity (V). Which has dropped off a cliff:

* https://fred.stlouisfed.org/series/M2V

The Austrian, Milton Friedman Monetarists have been squawking about inflation for ten years:

> We believe the Federal Reserve's large-scale asset purchase plan (so-called "quantitative easing") should be reconsidered and discontinued. We do not believe such a plan is necessary or advisable under current circumstances. The planned asset purchases risk currency debasement and inflation, and we do not think they will achieve the Fed's objective of promoting employment.

I consider the money I've spent on GME as equivalent to paying for comedy club admission. This is amusing.
Most defi is on Ethereum, which is making large scaling improvements. Zkrollups right now do several thousand tx/sec without security compromises, and data sharding will expand that by 23X in about a year. This is still probably a low volume ceiling by some definitions, but it's at least in the ballpark of major systems like the VISA network and NASDAQ trades.

Further down the road, more efficient data witnesses give another 10X. Also, the power of individual nodes affects both the number of shards and the capacity of individual shards, so future scaling is the square of whatever Moore's Law has left to give us.
People downvoted you but there’s some truth here. There’s only one thing that comes to mind:

> Then they came for me—and there was no one left to speak for me.

MySQL was the chosen store, chosen primarily for its (async) replication story which was better than Postgres back in 2012. Though I'm not sure it wouldn't still be a better choice today with the update load, I've had problems in personal toy (~20 million row) projects with slow bulk update speed in Postgres.

The last thing I did before I left was build out a mechanism for mirroring a denormalized copy of recent data in ClickHouse, partitioned by time (for matched) and type (for partials / unmatched). CH, being analytics oriented, works much better for the ad-hoc end user queries, which filter and sort on a handful of arbitrary columns - ideal for a columnar store. Interactive updates can be handled by CH's versioned merge tree table engine, and batch updates by rewriting the relevant partition from the source of truth in MySQL.

I chose CH primarily because it scaled down well for a columnar store - much better than anything in the Hadoop space. The conservatism of the market meant you couldn't just throw random cloud provider data mechanisms at it, nor a whole lot of fancy big stuff.

Can you think of a good reason why they just didn't freeze the whole market (buying and selling) instead of allowing institutional traders to buy and sell freely while only allowing retail traders to sell and in many cases forcing them to liquidate?

In my view the clearing houses had liquidity issues while many of their clients likely had solvency issues which this brick on buying alleviated.

And the IBKR chairman admitted as much.
I googled some of these issues as I faced them and I often found others hitting the same.

It seems like the particular model of SSD I got had a lot of issues for many users. The USB C port coming loose is also something I found other people facing.

What does their credibility have to do with the point being made? Are they right or aren't they?
It's a great example but if you understood options you would realize it's still a huge problem. I had quite a few call options on E*Trade when they froze buying. They sold me contracts and 5 minutes later made it impossible for the contracts to not decrease in value.
Have you had to pay for medical care, child care, housing, care for elderly or disabled loved ones and/or education?? How on earth can you say that inflation has remained low??? All of those have become insanely expensive and people die all the time because they can't afford them!

Just because cheap, crappy electronics and egg McMuffins don't appreciate in cost and stay crappy and cheap does NOT mean inflation is low. Anyone can play stupid games where you say inflation is low if you only pick certain goods made by robots or poor people overseas.
I mean the GameStop thing as a whole not this FB thing.
Yeah there's no technical reason not to at this point, China has it. Just inertia and having to invest in the systems and processes to do it, I guess. It started at like T+14 when you had to mail physical stock certificates around then +7, +5, +3, +2, I'm sure they'll get there eventually. US futures are already settled T+0.

From my limited experience back office software is a legacy clusterfuck and the Ops team has to pick up the phone and call counter-parties on T+1 to unfuck things more often than you'd think, but those are things that could be fixed with better systems if the investment was made.
You know, you can be against Facebook providing a platform to extremist/neo-nazis groups, and also think Facebook has overall too much power and presence.

It's not "you reap what you sow" and you're not handing GP some funny "gotcha". It's just plain obvious decency.

Some people don't get that, and then they're surprised that most normal humans think it's suspicious, as if they don't get it on purpose. Then they get upset because they start to look like nazi sympathizers.

That is what "you reap what you sow" looks like.
So it really is liquidity issues then. Anyone who keeps their trading at RH is seriously jeopardizing their money.

> Shares are moving electronically between different ledgers as orders are fulfilled

Ah, this is the disconnect.

They're not. Shares and payment for them move within two business days [1]. In the meantime, both sides must post collateral as a guard against their failing to deliver.

You're a broker. Suzy has $20 in her account. Suzy sells a share for $10. She buys another share for $10. With the first trade, you have to post--today--collateral against that $10 for two days. With the second trade, you have to post--again, by close of business today--collateral against that $10 for two days. To keep things simple, let's assume Suzy did not use the proceeds from the first sale to finance the second. That leaves you with $20 of liabilities and $20 of cash.

Next day, Suzy sells all her shares for $40. Now you're putting up collateral against that $40 for two days. The $20 from yesterday still hasn't arrived from JPMorgan--they have until tomorrow. You now have collateral against $60 of liabilities. At the end of the day, Suzy makes a withdrawal request because she's a little shit. So now you have $80 of liabilities from someone who deposited $20 in her account and never had more than $40 of assets.

Clearinghouses use the last day's closing price to determine how much collateral you need to post. They then multiply that by some value that ranges between 2% and 100%, depending on what their line-of-credit lenders offer them. That is leverage. To manage that risk, the clearinghouse adjusts that multiplier. Going from 20% to 100% in the above example would mean going from $16 of collateral required to $80. That's $64 of cash you need to come up with before the end of the day or you're out of business.

If Robinhood operated with zero clearing leverage, they would not be able to offer the instant-trading experience their competitors have offered since the 1990s.
