>What is not speculation is that they restricted the buying of stocks while not restricting the selling.

Yes but RH didn't have the billions of $$$ deposited at the clearing house for their trades to be honored. Buying stock to settle a few days later requires collateral that RH didn't have.

It may help to read through the answers: https://money.stackexchange.com/questions/136272/why-would-c...

This is why they scrambled at the last minute to raise billions to meet the higher collateral requirements: https://www.google.com/search?q=robinhood+2.4+3.4+billion

RH does some questionable things but their "restriction of the buying" is an inevitable consequence of not having the billions to meet any margin calls. They were the tail not the dog.
From my understanding, the reason the DTCC raised collaterals so heavily was mostly due to the risk on the short side. So they were protecting the hedge funds by protecting themselves, and it carried on to Robinhood. So Robinhood didn't really have a choice, but they still were protecting the shorts in the end.

I take a multi every day, but I’ll try this.
I’m not a fan of Robinhood, but everything that vkou has been saying is true.

My understanding is that Robinhood is self-clearing, not that Citadel is its prime brokerage.

The clearing margin requirement came from NSCC. Clearing margins CANNOT be satisfied using client funds. So it’s Robinhood’s own capital—and whatever credit lines they’ve negotiated—that would need to meet those requirements.

If I deposit 100k into Robinhood and keep it there as cash for 2 years, then one day I plunk all of it into GME, then until all my trades settle two days later, Robinhood will have increased clearing margin requirements based on the VaR of my unsettled trades. (Unless, my trade offsets someone else’s from within Robinhood, in which case I believe RH’s margin would reduce—but I’m not sure about this part.)

And if one day after my trades, GME’s stock goes up 10x, the VaR goes up roughly 10x as well. Even though I would have a claim to a lot higher value in my account once everything is settled, until the trades are settled, it’s a major cash crunch for RH.

The fact of the matter is that RH was not under-capitalized or have disproportionately small credit lines as a portion of their AUM, as compared to other brokerages. It’s just that their users were the ones that acted in a most coordinated way on a stock whose VaR was going through the roof.

In the case of laundering Bitcoin— this seems to be a majorly misunderstood concept. Bitcoin transactions are completely transparent and observable by everyone who has an internet connection. Anyone (with an internet connection) can watch any wallet and observe any and all transactions. The notion of a country being a "good location for laundering bitcoins" doesn't really make sense, as Bitcoin are never in a location.

In terms of profiting from surplus electricity, Bitcoin (or cryptocurrency mining in general) is a great option as it's exceptionally simple to scale up and down in accordance with available cheap surplus. One major benefit that miners are taking advantage of is locating in close proximity to energy stations, reducing the inefficiency of transporting electrical energy over distance. This turns effectively "wasted" energy in to a solidly efficient energy store for infinite amount of time— for example: 1 BTC will always be equal to 1/21000000 of the total supply.
Recruiters are getting more desperate and from what I've seen offers are rising significantly. And yet it's still not enough.

Hey at least I linked to some actual EA source code that will burn your eyes out. ;)

During that demo around 10:00, I accidentally fat-fingered the mouse and introduced a bug into the outdoor simulation. I couldn't figure out what I'd done or how to fix it, and we hadn't implemented "undo" in the code editor yet, so I just left it in. "There's all sorts of code like this in there. And it's kind of dangerous."

You're moving the goalpost from this particular actress, whose alleged "closet antisemitism" you are unable to prove.

So let's examine this "piece of art":

https://en.wikipedia.org/wiki/Freedom_for_Humanity

Indeed, if you were to conflate the depiction of Freemasonry/Illuminati and big noses with the "Jewish World Conspiracy", you might interpret this mural as "antisemitic":

https://en.wikipedia.org/wiki/Judeo-Masonic_conspiracy_theor...

However, only two of the depicted figures are actually Jewish. As with Israel, you can make the same distinction between "antagonists that happen to be Jewish" and Jews in general.

If you buy into "horseshoe theory", you may well assume that some leftists must be stashing copies of "The Protocols" somewhere, ready to distribute when the time is right. However, for now I still don't see the smoking gun.
Popcount is easily recognized by llvm (and it’s actually mentioned in the article...)

In the case of the code you’ve posted, you’re shifting out the LSB before you check the bit, so it’s not quite right, but (in general) popcount is recognized and used when possible.

Give me an (real life) example where these errors matter. Any real data will be noisy anyway and relying on anything at the level of ppb (parts per billion) looks suspicious.

Clarification: I do not say that treating floats careful is not important, and I know doing stuff like subtracting large numbers can lead to inaccurate leading digits. This is clear and part and parcel of any numerical work. But this is not what the article is about. I am claiming instead the article is looking for a problem where there is none (or let's say I fail to see) .

I agree with the rest of your comment, but there's some sleight of hand here:

> This turns effectively "wasted" energy in to a solidly efficient energy store for infinite amount of time— for example: 1 BTC will always be equal to 1/21000000 of the total supply.

It's not an efficient energy store if you can't get the energy back, it's just energy usage. Also, yes, 1 BTC will always be the same fraction of the total supply, but the actual value of it varies.

What types of trips? Distance traveled isn't really a relevant metric if you consider that cars may be used between cities (where distances are longer) and bikes inside of cities.

I'm from the Netherlands, 30 years old and have never owned a car. I do most everything by bike and public transport, occasionally if the situation calls for it I rent or borrow a car (I know people with cars that, unsurprisingly, aren't being used all the time). It certainly depends on your exact living situation, but my impression is that infrastructure plays a big role. I lived in Amsterdam for 12 years, and almost everything in that city encourages you to use a bike, and almost everyone does. Recently I've moved to Germany, and even though it's generally considered a bike friendly country with lots of people owning bicycles, the infrastructure doesn't compare. Dedicated bike lanes are way less common, and whatever is there is often bad quality (avoiding bumps all the time is really energy consuming). Again, unsurprisingly, people use cars here over distances where it wouldn't even cross my mind.

Of course distance matters, and cars will be preferable for long distances with bad public transport connections. I've never found driving a car inside a city to make a lot of sense though, it's often not even faster taking congestion etc into account. Put the bike infrastructure in place, and people will use it. Lots of Dutch train stations now have what's referred to as a "public transport bike", a few euros lets you borrow a sturdy bike for a 24-hour period. Take a train into town, do the rest with the bike, it's all really simple and fast. I see this being added to large parking spaces outside of cities in the future (maybe they already have - I don't own a car so I wouldn't know ;]).
Speak for yourself, this is the third sun I've planted this millennium and you guys need to take it easy with it.
Here in Portugal the louder voices speak for public transit - greener, fairer, etc etc. You know the usual arguments.

Unfortunately massive public works are by far our biggest source of grifting. It takes an average of 20 years and $120M/mile (60M €/km) to open a new metro station.

Maybe Switzerland doesn't have this problem, but I'm all for solutions that take funds away from our politician's hands. And the car is great in that respect, as long as you don't advocate to increase road capacity at a massive cost.
No, it's a 2/3 chance at that point.

When you choose initially, you have a 1/3 probability of getting the right one, leaving a 2/3 probability that the car is on one of the other two.

The host reveals one of the other two. So that 2/3 probability applies to the remaining door. Here is a short C implementation that made it very clear to me...

#include <stdio.h>
#include <stdlib.h>

int doround () {
int car = rand() % 3;
int firstchoice = rand() % 3;

// host reveals one of the goat doors

if (car == firstchoice) {
// you changing to the other door after the reveal is a loss
return 0;
}

if(car != firstchoice) {
// you changing to the other door after the reveal is a win
return 1;
}
}

int main(int argc, char** argv) {
int wins=0;
for (int round=0; round < 1000; round++){
wins+=doround();
}
printf("Worked in %d of %d rounds\n", wins, rounds);
}

Yeah, I also have found the abrupt jolt of silence (from podcast or audiobook) can jolt me awake, and also that all-night droning on also disturbs me and wakes me up.

Apps that can slowly fade out the sound are great. The Audible app fades out very quickly, but even that quick fade is enough not to wake me if I am already asleep.

(If I am awake, though, I find that it disturbs my "almost asleep" vib, so I wish they had an option to fade out over x minutes.)
My experience over the years, especially for "information workers", is that location does not matter to productivity.

> In Lisbon we could easily double or triple the speed and amount of traffic flow without any investment by getting rid of a few thousand spots of street parking.

Agreed, but surely the best arrangement in a dense, traditional city centre is not to have high speed traffic at all except on a few large thoroughfares, and to reserve most other streets and alleys to pedestrian use.

It seems you misunderstand. Illicit fiat and extortion can be used to access energy to mine Bitcoin, effectively laundering that illicit fiat.

> Why do people still have to attack religion?

Because religions are still dangerous animals, if you would indulge this metaphor. Just because we managed to declaw and tame one (values of Enlightenment supplanting values of Christianity), it does not mean that we can treat all of them imprudently.

I suggest that you are arguing from the point-of-view that "my $ANIMAL is well-behaved and has not and would not hurt anyone". Is that true?

I'm a brit, we're not doing much better than the US. But no one really takes the US seriously as a democracy.

Partly for the reason you yourself give: propoganda and fake news. Partly because the US system is just such a mess (the senate has so much power and seems designed to be antidemocratic for a start). Trump and Jan 6th are just the icing on the cake.
Bicycles replace both walking and driving trips. In Dutch cities, most people walk or cycle to the grocery store, which is a great example of cycling replacing walking trips.

In smaller villages however, that are more spread out and usually only have one or two grocery stores, people usually take the car or their bike to the grocery store, because walking is too far. In this case, bikes do replace trips by car.

Also note that in general, Dutch cities are quite walkable and cycleable. If I visit a friend on the other side of the city I live in, I go by bike. Which is about as fast as going by car. Going by public transport also takes about the same time. This is a result of the Downs-Thomson paradox [1].

Survey on funding of open-source projects
Hello everyone!

I have seen a lot of discussions in the past about the sustainability of open-source development and how this can lead to burnout with some of the maintainers. However, these are individual voices and I would like to collect a broader understanding.

I want to start an initiative to improve the situation for maintainers and for this, your feedback would be really helpful.

If you are interested, you can find more information here: https://survey.makemake.sh/

Thank you very much!

Maybe that's just me but flexible-location on the other hand to me suggests that the person is constantly on the go, e.g. in a café.

Given the shitty internet situation (might just be here in Germany though) and background noise anywhere that is not the office or home (which seems to be still bad in a lot of cases), that doesn't seem too desirable of an image. Those factors are what cause the location in "flexible-location" to be home 99% of the time for me (and probably many other people).
> Hedgehogs are at stage 2. You move from stage 1 to stage 2 by adopting frameworks; hence, hedgehogs are seen as "thought leaders" because they teach the frameworks that lead MOST people to more mastery. Except when you're at stage 3, in which case frameworks lead you to more inefficiencies compared to your own understanding.

While interviewing recently, I've found a similar anti-correlation between general competency and people who focus on teaching frameworks and libraries.

The more competent candidates basically don't do any teaching based on frameworks/libraries (but they might have experience mentoring individuals); whereas the candidates who focused on teaching frameworks specifically (often to groups) were the least competent - the more they focused on teaching the less competent they seemed to be! I found this kinda surprising and worrying, though my sample size is fairly small. To clarify, I know only so much can be evaluated in an interview, this is basic competency.
It started for me after I got vaccinated and rode in public transport for the first time in a year. I was reading some articles back then on HN about how readjusting to “normal” life is particularly difficult for some people. I’m thinking it might be this. Inner turmoil that life will be normal again and the stressors of life will come back. I dunno.
> packaged is a word that doesn't make sense unless you explain it. Do you mean putting the end product in a box?

My favourite personal example of this was a "big project" I was working on in the early 2000's. There were two QA reviewers for my project plan:

One raised "serious objections" to the QA section, saying it wasn't detailed enough, we needed a full test plan, and demanding TDD be used for all development. They cc'ed the CEO with their review.

The second QA reviewer said the test plan was a "good high level approach" and that only thing they wanted to see was an explicit "design for testability" requirement for one of the critical, and hairy, modules.

Oh wow. I am literally slowly working on something like this as well. But my knowledge of mapping technology is very limited.

My focus was actually much more on trying to use partly public data, and partly contributed data in order to 'render' information on top of such a map. My vision was basically to have all historically known people and there locations being visible on the map. Wikidata already has a nice start to this, but you would need a contributor model to flesh this idea out quite a bit more.

Another step after that would be the movement of armies. This could be really interesting if you could see armies moving around at different times and getting closer to each other, or pass each other by.

City population is another interesting thing. There is no easy way today to get a good estimate of what some city X population might have been at any particular period. That information is buried in all all over the place.

There are many more ideas, but having his historical map is actually awesome for me, because that was the part that I know least about. So it should be an amazing piece of the puzzle.

I will defiantly try to contribute to effort.
I think that's a fair comment. Re-using the word "energy" in that sense is potentially misleading to always mean electrical energy.

As for the value of 1 BTC, it's value fluctuates if you operate on a base currency which is not BTC, but that is the same for any currency exchange.
