This is why we have the term, "capacity constraints." Melvin accomplished those returns in a year where they would have started off with $10B or close to it. The retail investors you know did it on what, $100k? $1M?

The liquidity available to retail investors is completely different from the liquidity available to firms with an 11 digit book. Assuming those retail investors actually have a working strategy, they can basically invest in anything.

If they find alpha in trading some overlooked company worth $100M total, they can deploy all their capital and make an outsized return. If a multibillion dollar hedge fund finds alpha in a $100M company, they can make a great return of 50% on let's say...0.1% of their capital, assuming they can buy 10% of that company without meaningfully moving the price against them.

So you have an 11 digit book, and you have to get an outsized return. You either find tons and tons of these little tiny companies you can buy single digit percentages of, or you win on big bets from a blue chips that can absorb your liquidity. Or some mix in between. Or you expand to foreign assets, or another class of asset that can handle the weight you're moving around. But you are fundamentally limited, and whatever you do has a different profile of risk attached to it. You are also bound by the risk thesis of your firm and what your investors' goals are.

That's not to say all hedge funds outperform retail. A lot of them plainly suck and fail to accomplish their mandate. But this is too uncharitable a take; the liquidity and risk characteristics are completely different. It's incomparable.
The key part you highlight is that of hiring. If you want to be scale ready from day 1, you may not find the scale out talent because they either are working on large scale problems or would want to work on large scale problems. In your early days, you are mostly hunting for a product market fit.So your problem statement will not even be relevant to the hires.

This is the best case, the worst case is that the scale out thinking hampers your product market fit progress. That's the risk you run.

So, while it seems to have gone scale out on day 1 in hindsight, it's always always better to start small and scale out as needs arise, even if that means re-architecting the whole stack. It's painful, but doable. It's also a reasonable challenge to entice new hires. You have scaled out a system from degree 1 to degree m. Now scale that out from m to r++. Something like that.
When the media fails to do its job then the people have to do it for them. Of course there will be condtradictory information coming in because the media has completely failed to provide a source of credible information. I'm not throwing out misinformation, but merely pointing out information that the OP missed and is available in reputable sources. There is A LOT of video evidence that points to BJP stooges inciting violence. The guy who hoisted the flag on Red Fort, Deep Siddhu is a known BJP supporter. Times of India , Indian Express, The Wire have all reported on this. Heck even Aj Tak had video where the BJP stooges are throwing stones at the protestors while an entire police battalion stands behind them doing nothing.

Smart store managers would indeed do this. But they also don't need unreliable electronics to tell them what they know from walking around the store.

1) Grocery stores are optimized to hell and back already since the margins are so terribly thin. Industrial engineers have been over every shelf and aisle several times already.

2) Grocery stores have seem to have reoptimized roughly about 2-3 years ago. It seems like all the grocery chains suddenly remodeled and converged on a new layout.

If you own an Intel CPU, you are far, far more likely to have a Nvidia GPU as well.

I remember seeing that correlation many years ago, also on the Windows side, and likewise most people with an AMD CPU also had an ATI GPU. The acquisition of ATI by AMD seemed quite natural after that.

(I personally have the Intel+Nvidia combination, although it's very old, and I don't use Linux as my main OS.)
I kept seeing people saying Friday would be the reckoning and offering various contradictory reasons that orbited around “the margin call expires and they have to buy”. Nobody could say what time the margin call would “expire” or provide a source explaining how that worked, and when none of those things happened and the stock rose back to 300-ish and closed, everyone just updated their takes to Monday instead.

How do we know this won’t just sputter for another week or two and then end in the most anticlimactic way possible?
I don't think the big players attack each other like this. Its too traceable and if word gets out, it can come back and bite them.

The smaller the amount of capital you manage, the “easier” it is to get large returns on a % basis. There’s a video where Warren Buffett talks about this behavior (a bird hunting club that ended up finding oil, hopefully someone can find the video for me).
> The bigger problem is that this is rarely just a one-time decision to gamble. And repeatedly doing this is statistically pretty certain to lose you significant amounts of money—particularly when compared to just investing in the market as a whole—over the long run. It’s just another way that the poor are trapped in poverty, even though you can of course always find individual cases where someone got lucky and made millions.

Even with negative expected value, playing a lottery could be a rational decision given the right motivations and circumstances. Suppose for some reason you expect to be living paycheck to paycheck your entire life, barely having any surplus, and that there's nothing meaningful you can do to alter that trajectory. Investing scraps every month at 10% average returns (especially if you don't start till you're 30+) might allow you to retire a month or two sooner, buy slightly newer clothes, or maybe eat out a few more times each year, but even if you just lit that cash on fire you wouldn't have a substantially different life. However a few chances at $250k+ could fundamentally alter your possibilities, giving you a freedom that you otherwise couldn't dream of.
That wouldn’t be as fun though...
I'm not totally enthusiastic for this feature, but that doesn't appear to be the case either.

It looks like navigator.hid.getDevices() will only return devices that the site has previously explicitly requested (with the vendor and other IDs) and the user has granted permission to access.

So it doesn't look like drive-by enumeration is possible with this - websites have to explicitly request to connect to a specific device, and the user must manually approve each device.
> they make a ton of money ($100M/Q I've seen) from one of the big players in this (Citadel).

No. Citadel Securities (the market maker) is a separate entity than Citadel Investments (the hedge fund). Citadel Securities is making money hand over fist from GME. As they always do during periods of high volume and volatility. Robinhood shutting down trading in GME almost certainly cost Citadel Securities a fortune in lost profits.

Nor is there even any real evidence that Citadel the hedge fund has a very significant exposure to GME. For the entire month of January the main funds have only lost 1% in GME and 3% total.[1] Probably less in total than the amount Citadel Securities has made off the trading.

It's solveable but the cost will be huge. The immediate problem is drainage of rainfall. Even a slight rise in sea level will drastically reduce the rate of drainage and lead to frequent flooding. So roads and buildings will have to be elevated and new larger drainage channels dug, with pumps in some places.
I think the elephant in the room is not He's work, but the fact that embryonic selection is already commercially available from Steve Hsu's Genomic Prediction[1] and other companies.

It doesn't impart new genes, so it can't give HIV immunity if the parents don't have it, but it can screen large numbers of embryos and allow the parents to select the one(s) they want based on their genetic makeup

It is done using well established technology and can select the factors that people really care about: intelligence, and freedom from disease, gender, and mental health.

Genomic Predictions is already working with 200 IVF clinics and screening millions of embryos a year. Many countries have laws against using the technology to screen for anything but disease (e.g. higher intelligence), but some do not.

I’m considering proposing this just to watch my security friends’ heads explode.
Did you read the SEC release?

What? It can get way worse than Google. For all the privacy invasive things that Google does it’s one of the least bad. Unlike most companies that collect data it doesn’t directly sell user data, and it has a good history of avoiding security vulnerabilities that leak data.
Thanks for the feedback, and the submission :)

When you say "keyboard does not produce sound", are you saying that you'd expect to hear sound when pressing a physical key on your computer keyboard, like "C" or "1"? Or are you saying that you're clicking an element in the page and not hearing sound? I really like the idea of responding to physical key presses. If you're into Svelte, perhaps you'd want to take a stab at adding that feature... wink wink. I actually already have a ticket for it here: https://github.com/seancolsen/octave-compass/issues/74 My thought was to use the number keys to play the scale degrees, but I'm open to other ideas.

> they only profit when they make good loans

An interest bearing loan is, by definition, not good. It's predatory. So it means that those banks profit most on the most predatory loans, exactly as I was explaining.

> You yourself said the law is wrong for continuously accumulating interest on an unpaid debt

That's part of it. The argument is that the law protects interest bearing loan contracts instead of nullify them.

The hardware is probably much better now, if one pays attention, but still, it's a big gotcha.

> If you really think this through, why would they actually announce they have covered the shorts instead of simply reclaiming a short position?

This is paper thin logic. If they hadn’t said anything publicly, you and others would be commenting, “See! Melvin Capital hasn’t said anything, so they’re still shorting GME.” It is incredibly common for investors involved in public battles over a stock to announce they’ve closed a position, see Bill Ackman and Herbalife (https://www.investopedia.com/news/billionaire-bill-ackman-du...)
Bull market gains are easy to brag about. It’s high year to year gains over varying market conditions that is the goal.

Though you could argue the hedge funds failed to see the influence of the retail investors entering the market and missed out on the gains.
That is not what naked means. Naked short sales are short sales without an executed or agreed upon borrow between the borrower and broker. You are referring to short interest higher than 100% of the float (total shares in circulation), which is mundane because it happens organically when a lot of people want to short the same thing and start borrowing shares which were already sold short.

It seems entirely unsurprising to me that a brick and mortar retailer selling digital goods in the middle of a pandemic would be a hot short target for many different funds, thereby organically pushing short interest over 100%.
I run a non-federated instance on a tiny 2GB RAM ARM SOC. About 4-5 active users. Extremely light (under 80MB RAM usage) as long as you don't federate. Attempted enabling federation once - maxed out all cores, all mem/swap, and basically blew up the entire machine. Had to wipe away the database and start without federation.

Encryption UI is a mess. I have actively tried and failed to set up E2E encryption with at least one other technical user. Recommend disabling encryption unless you want non-technical users to abandon ship immediately.
2-3 weeks ago when share prices were around $17, GME had a market cap of less than 1.2B. WSB has 7.6 million users now, but I assume it went up a lot recently. Say 2 million of them bought some GME. To buy 50% of the shares a couple weeks ago it would have only taken $296 each. So they could ABSOLUTELY get prices moving significantly. Now of course lots more people have jumped on now. But that 20B volume number is after they got the price to ramp up!
Private companies go bankrupt all the time. Large public companies (like telcos) are slow, inefficient, monopolistic etc. Large defence contractors in the US are responsible for bribing officials and corrupting the US democracy. My point is that large organisations fail all the time. It doesn’t matter if it is public or private.
That's a nice idea. I suspect they must really be trying to keep the BOM cost down though.

I was struck by just how little there is on that board other than the Spartan-6 FPGA; which looks to be one of the smallest versions of what is now a 10 year old design.

There's one SOP/SOIC-8 package by the FPGA which I assume is configuration flash. One 50MHz crystal near to that. Some power regulation on the right-hand side of the board. One Alliance SRAM package. And that's it other than the passives and connectors!

I guess it's possible there's some interesting stuff on the other side but I'm doubting it.

EDIT: Wow I see they are selling this for GBP 300; which is over USD 400. You really aren't paying for the hardware; this has less content than a USD 70 dev board.
How can this possibly work with incompatable libraries?

It says that Bedrock provides the glue to make it work, but it does not come with specifics on how it has solved what seems to be a rather hard problem to solve.
I can’t imagine that a bunch of millennials buying and holding 5 shares of stock on GME is causing this. They’re just getting the blame for it.

Instead, I think other hedge funds are in the water. The sharks are circling and they’re battling each other. One side is shorting. And the other side is going long.

The volatility on this stock is great. And you can play both sides. And the market makers makes money on both sides too!

Beautifully written. Domestication is apt-its userbase has largely been kept blissfully ignorant and still a huge chunk of its users have no problem using it with the term changes.

I guess the big deal is that if your friends who aren't accustomed to authoritarian style governments no longer wants to talk to you because you are on Whatsapp then it will force those people to stay on it at the risk of looking stupid and ignorant.

I rather not talk to friends or people who refuse to stop and look at whats happening. So many of them say "I have nothing to hide so whats wrong with this?". They are fully domesticated.

You don't need to think one way or another. There's a process called "Discovery" and we'll likely get to it and find out what happened. Or they'll settle and we won't find out. Given the number of class actions this will happen.
It's not really about presentation of balance sheets, it's about liquidity. The explicit purpose of market makers is to provide liquidity, so they have a special exemption to buy and sell shares without being certain they exist. They have to have a good faith belief they will exist though. Usually they're right. Occasionally they're wrong.

Ask HN: How to Deal with Mistaken Identity?
I’ve just come to realize a bunch of people in a very online subculture I kind of barged in and out of last year think I’m some other horrendous person or persona P. I actually don’t know who P is but I just know he or she has somehow pissed off a lot of people. While I don’t have to worry about getting fired or emotionally startled (https://en.wikipedia.org/wiki/Sunil_Tripathi) I’m worried this might affect my personal reputation going forward.

What’s the best course of action going forward?

I’m assuming its to just ignore everything and carry on since I'm a nobody. In the worst case if it does seep into my personal or professional life I will just explain the confusion. My thinking is people online seem to get distracted by some new thing sooner rather than later.
> It means, mathematically

In this case we're not in a mathematical context though.
The upshot of this is that Citadel is selling retail GME at slightly elevated prices for profit. This will certainly contribute to higher GME prices. If Melvin is still short, Citadel is in a predicament. If they want the price as low as possible for Melvin’s sake, they need to actually provide the best price. I thought that was funny.
Early Illustrations of the Nervous System
Sure, but I'm not talking about complex strategies here. If you can't beat a retail investor with a straightforward portfolio of middle of the road stocks like "AMZN, AAPL, BRK, DIS", what is the point of a hedge at all? Particularly when their tactics put them in such a high risk category.

All of what I'm talking about would have scaled perfectly fine with a $10b portfolio, these are giant corporations with a combined market cap around $4 trillion.

>Wages are up 10% since 1963 on an inflation adjusted basis

And they're down 5% since 1970. Claiming that chart shows growth is a gross misreading of that source. The slope of the trendline since 1963 is practically zero.
YOU felt like you owned your computer because you're a tech nerd, software developer, or similar.

That is not the feeling a "Wild West" environment gives to 99% of people using these devices. It is much closer to Russian Roulette than anything else.

Killing app stores would paradoxically dramatically shrink the market for software and cause massive consolidation on the developer side. The big players with big budgets and marketing clout would survive but it would devestate most others and shrink the overall market by 40-50%. It doesn't take a genius to figure out why by applying the same principles folks on HN use every day to optimize customer acquisitions, increase ARR, etc. When every app asks for your credit card (and they would) you automatically shrink the funnel dramatically. That doesn't even begin to consider all the scams, subscriptions you can't actually cancel, or malware that deliberately subverts sandboxes or plays silent audio to continuously run in the background to kill your battery.

There's a natural incentive if stores compete for developers: reduce commissions. The end result of that is get rid of review or any other quality control standards because those things cost money. The large players won't participate because they'll want to keep everything for themselves. You can forget about anything that improves privacy or makes your life easier as an end user.

For end users the bar to jump through all those hoops and take on the security and financial risks will be much higher. They will buy less software.

It amazes me how quickly some of my fellow nerds will fall into the same myopic traps over and over without consideration for the other 99% who aren't computer experts. And without consideration for what it takes to actually run and be successful in business. Just because it would be more convenient for them personally.
