Interested in how common broken bones are today, I stumbled across this study:

> There were 6451 men and 6936 women followed for a median of 3.0 years. During this time there were 140 incident limb fractures in men and 391 in women.

Whereas OP's archaeological study had:

> Fractures were more prevalent in males (40%, n = 57/143) than females (26%, n = 25/95).
>We need more clarity on: Why did the DTCC make its decision? Was that decision properly communicated to the market, or did some firms get early access to the info? What conflicts of interest do they have? Was the DTCC lobbied by other Wall Street players to make that change on Thursday?

Isn't the formula public? https://twitter.com/kralctrebor/status/1354952686165225478
Payment for order flow can certainly be controversial among people who understand the market. Also, there are plenty of people who understand the market who find the concept of the market controversial.

Your circles might all be comfortable with PFOF, but I wouldn't say it is controversial only with those who don't understand the market -- it's dismissive of contrary opinions.

Sure, when Kotlin/Native was introduced they had the clever idea to force a memory model incompatible with what any JVM written code would be expecting, so you need to explicitly write Kotlin/Native aware code.

I can't read this long article at work, so I've no idea what it says about the film. But this movie is also one of my favorites. My sisters loved it as kids and I know people who can quote it word for word.

I've seen this movie get flak for being uninteresting or one of Disney's forgotten endeavors but it's a gem.
Oh, indeed. It's nothing incredible. Kids love it, but it's definitely small. It's still a converted velodrome, after all. Its proximity with the Botanical Garden and Planetarium are nice though, and those two I really like.
Nvidia spends several times as much as AMD on software. If they have that much more money, why is AMD able to ship more stable drivers? I just don't see how this holds any weight.

These companies aren't rewriting tens or hundreds of millions of lines of code for Linux. The difference is probably a fraction of a fraction of a percent.
Isn't the benefit of open source that you can just revert back to the 5 month old drivers and wait out the instability?
> Linux users don't have to refresh hardware as often. Long-term support is a cornerstone of linux.

I'm well aware of that (since I'm one of them too), however I didn't make it clear I presume.

Thanks for highlighting it again.

It's also stems for efficient utilization of the hardware, too.
All brokerages make money from PFOF -- but it is a much larger revenue stream for RH compared to other brokers.

https://www.morningstar.com/articles/1015686/robinhood-was-i...

"That Robinhood sold its order flow is unremarkable, but the scale of its activities certainly merits comment. Forbes reports that in the first quarter 2020, 70% of Robinhood’s revenues derived from payments for order flows, as opposed to 17% for E-Trade and just 3% for Schwab. Yes, Robinhood has observed standard practice–but with distinctly above-average enthusiasm."
I agree that they're shady, and moved my account out last week, but their pricing is exactly the same as Fidelity, Schwab, and Vanguard. Would you recommend using a broker that charges a commission to buy?
The comparison shot was taken with a drone at an altitude that corresponds to our 10cm resolution. The 30cm version was obtained through downsampling the 10cm image.

Other companies could potentially drive towards higher resolution, but spatial resolution isn't everything. You give up temporal resolution (revisit rates) and overall area coverage, so we expect some companies to continue to cater to the lower resolution type applications.
Of course, even if average productivity per capita in China is half that of America, the total output will be twice as much. No one serious in Washington (or Moscow or Brussels or Beijing, etc.) believes America could win a war on China's home turf even if nukes are untouched. Same with India to a lesser extent.

It's not even a secret at all to at least millions of folks across the world. It's only the strange American media and brainwashing system that presents the idea that China can be threatened with force.

In that sense it's highly dubious Beijing is directly involved with Myanmar's current regime change. They can achieve their objectives anyways without getting their hands dirty. Of course there may be intermediaries involved that straddle both camps so it's not clear cut either.

They do, though many of them will intentionally word it differently and try as hard as they can to not get flagged EM and have to explain it to their company. Sometimes ATC has to repeatedly ask them if they have an emergency or need assistance, meaning to roll the ground vehicles in place. I've repeatedly heard that the airline industry can be brutal to pilots. Even if they have 20k hours of perfect flight time with no incidents, one incident can ruin their career. No idea how true this is.
Fintech spy – the best fintech and neobank tracking tool
Thanks for the answer! It was clarified in the website, but the "9x" sentence was still ambiguous. Very often, image processing people will understand "resolution" as a linear unit, like dpi or gsd. Using its square seems strange, likely only useful for marketing purposes, and thus a red flag for technically minded people.

That said, 10cm per pixel is impressive if you manage to pull it through! Cannot wait to buy these images!
Hey folks!

"Fintech is eating the world", as a16z says, but right now it can be pretty hard to keep track of:

- what companies exist

- what countries they serve

- what products they offer

- how large they are (users, employees)

- whether the employees are happy

- whether the users are happy

- how much they've raised

- whether they're part of the social "zeitgeist"

- etc

So I built http://fintechspy.co/ as a way to more easily stay up to date with what's going on.

That's pretty much it, would love any thoughts, feedback, etc!

So I'd say the truth came out in an interview late Sunday evening between Elon Musk and Robinhood CEO Vlad Tenev. [1]

> Tenev explained that while he was sleeping, at 3:30 a.m. PT on Thursday, Robinhood's operations team received a file from the National Securities Clearing Corporation (NSCC) that as a clearing broker, Robinhood Securities needed to put up around $3 billion "an order of magnitude more than what it typically is."

> So, it was unprecedented activity. I don't have the full context about what was going on, what's going on in the NSCC to make these calculations," Tenev added — prompting Musk to joke if someone was “holding you hostage right now.”

> Tenev said that after putting their heads together and calling the higher-ups at the NSCC, they got that figure down to $1.4 billion, from the initial $3 billion. "We were making some progress, right, but still a higher number," he added.

> Next, Tenev said they had to explain how to "manage risk in these symbols" by restricting activity in the volatile stocks. After that, the NSCC said the charges on the deposit were $700 million, which Robinhood "paid promptly."

You don't even have to read between the lines here. Robinhood isn't the problem here. Massive long retail demand is crushing shorts, which is potentially opening the clearing houses to multi-billion dollar losses. The way to stem the losses is to stem buying pressure and get the stock to come down.

So call up Robinhood and demand $3 billion in collateral (an order of magnitude higher than the day before) unless they stop the buying pressure on the shares. When Robinhood agreed to limit buying, the NSCC was willing to drop the collateral requirement to $700 million.

This isn't about a share-for-share clearing / transaction cost for each buy order entered. Those buy orders are cash funded and zero risk for Robinhood and zero risk to NSCC / DTCC. This is about extorting Robinhood to stave off the bankruptcy and subsequent contagion of a 140% short interest on a stock that's gone up 70x in just a few months.

Look, I agree that Robinhood can't use customer funds to pay extortion demands from the clearing houses. My point is that Robinhood clearing fully cash-paid buy orders does not incur additional clearing costs to Robinhood. It's not a per-order transaction fee. It's a slush fund which is used to pad against defaults.

> "Now, why is that so high? Like this seems like, it sounds like an unprecedented increase in demand for capital. What formula did they use to calculate that?" Musk asked.

> To contextualize the number, the app's CEO noted that RobinHood had raised about $2 billion in total venture funding. He added that the formula was “not fully transparent” and “not publicly shared.”

When someone borrows a share, do they pay the current share price to borrow it?
I never said it was a moderation failure, as I said it was politely given.

And I'm not providing links because I don't have them, these are things I've noted over the years as a lurker. There's so much back patting about the moderation on this site that I'm often miffed that no one sees the negative consequences. No system or approach is perfect, and the approach you guys take on this site has its share of downsides as well.

I once saw a person on this site argue all safety regulations should be gotten rid of and let the market decide the cost. The theory is that as more accidents happen the insurance will rise and that will self-correct by causing companies to enforce their own internal safety requirements.

The implication being it's ok for Bob to live the rest of his life without a leg because the company was willing to pay the insurance premium. That Bob's quality of life shouldn't factor into the equation.

The problem is that when someone has an opinion like this, they cannot be put down as strongly as they should. "In real life" if someone walks into a public space and announces they believe a 30 year old should be able to enter into a sexual relationship with a 10 year old, not only would there be a reaction, there would be a __very strong reaction__, and the strength of that reaction is a part of the policing we do amongst ourselves as a society.

But because of the values this site has, if someone were to express that opinion on these boards, the people getting banned would be the ones reacting strongly.

And _THAT_ is why I agreed with the other poster that you do, in fact, moderate based upon HOW someone says something while pointing out that it has its downsides.
DTCC needs to be investigated again. They were previously accused of allowing naked short selling[1] and their complete control of the system is problematic.

> they take out a large short position, then they publicise their research. If the market agrees with them, the uncovered fraud tanks the stock price, and they make a healthy profit.

This is giving the market a lot of credit for being a rational and well-informed actor. The market is not full of people who calmly evaluate a short seller's argument and make a logical decision. It's full of people who lack the time, experience, and confidence to question the "financial expert" making dire predictions on the morning news and think "I should get out of this stock just to be safe".
Highly recommend this WeBull interview that covers all of that in extreme detail: https://www.youtube.com/watch?v=4RS4JIEVyXM&ab_channel=Benzi...

You're right. But the problem is, DTCC is a monopoly. They cover 95% of trades on wall street. Would anyone, even the SEC, dare risk destabilizing the global financial market by constraining them from taking supposedly-prudent measures to limit their risk? Because that's how they'll spin it, perhaps.

I have a physics degree. I think an interesting thing about physics education is that it teaches resourcefulness and opportunism. Physics "owns" relatively few techniques and technologies. It borrows from others, and combines things.

One of the reasons physicists like programming so much, is that it's the modern duct tape for putting disparate things together, and there's so much stuff out there to use.

Physicists are always among the earliest users of technologies -- vacuum tubes, transistors, and successive generations of computers. At my college, the earliest adopters of personal computers were all physics professors. The one exception was a humanities prof whose kid happened to be a physics major.

I think it's possible to tell by looking at his actions. If he actually believed in 2016 that there was massive fraud, and a risk of the same happening again in 2020, he would have done something about it. If anyone believes he was sincere, the fact he took no action for so long in inexplicable. You'd think it would be a matter of vital, urgent concern.

The fact that he ignored the whole issue until it was convenient for him to do so again speaks volumes. So I think it's perfectly clear, he doesn't believe a word of it because he doesn't act as though he believes it, and none of the people in the Republican party who say they believe him actually act as though they do either. They are doing nothing whosoever to address he problem, because there's nothing there to address and they know this perfectly well.

I went looking for 2.5 inch NAS/ video recorder drives this past weekend and came up empty handed. I’d hoped to install them into a mini-pc NVR. The form-factor doesn’t appear to lend itself to the reliability drive manufacturers target for this class of drive. They’re optimized for high write speeds and very high write loads. You can of course use consumer laptop drives in a NAS, but write speeds will be lower and reliability may suffer.
New study finds that narcissists are less willing to self-isolate
Observing how traditional auto makers handle the transition to electric cars indicates that this is not an easy step. VW was the first big automaker to introduce a pure electric platform at the end of 2020. Most other auto makers so far have only electrified existing ICE designs.
There are countless controversies involving Robinhood.

One that I only learned about a few days ago involves an investor who was erroneously shown a -$700K balance on his Robinhood account and then killed himself as a result[0].

Back in September of 2019, I made a deposit into Robinhood. The next morning I received an automatically generated email saying that the deposit had bounced and that my account was now limited. I checked my bank account and saw that the funds had indeed been removed. The email included the ACH error code "R26", which corresponds to a malformed ACH file. I quickly learned that every single deposit on that date had failed [1].

No worries, I thought, I'll just email support and let them know. Unfortunately their support was completely useless and did not follow through with what they said.

I switched to TD Ameritrade (and the thinkorswim platform) and have not looked back.

I think Robinhood needs a sort of Uber-style restructuring. It's clear they do not care about their clients.

That's incorrect. Otherwise people would be able to freely share music and movies.
The word you're looking for is "Lose" not "Loose".
For sure, and if you require a bunch of the other checkboxes be checked (ability to change price, actual change in price, artificial prices) for a single individual or in an explicit conspiracy between individuals it gets even harder still. The laws around this grew up when this was all mostly done in private or between groups of individuals that were keeping things private (at least at the start), or were paying significant money to explicitly promote something.

Posting about stuff on the internet in public and causing a defacto stampede, especially when it happens after hundreds of other unconnected strangers start posting their own thing? Not sure there is any precedent.

$ls -l --time-style=long-iso # print time format yyyy-mm-dd hh:mm

Other nice combinations:

$ls -alsSh # print all files in a long list format, using size option + sort, in a human readable format
Those contracts are generally secret. You have to trust your broker will negotiate a good split on your behalf. (Or hope the SEC will smack them if they don't, as happened to RH.)

You understand that if GME drops to $80 today, a large number of GME trades from last week are going to refuse to settle. What is Congress going to do? Force the DTCC to eat the losses?

The article is a bit confusing. There's "PFOF" which is basically middle-man profit taking. That's not particularly shocking unless it's egregiously delayed. But then there's selling data to high frequency traders.

This sentence in the article conflates these two very different things...

> As we saw above, Robinhood’s main revenue source comes from selling customer trade data to other firms. This is a controversial practice known as “Payment for Order Flow” (PFOF in financial regulatory lingo).

I am not getting this? Is it the case that ordering stock shares from a market maker like Citadel is identically selling data to high frequency traders?

FWIW, I admit I don't _really_ understand how market transactions work, and I definitely don't feel alone!
Oh yea for sure, it's all just propaganda, nothing to do historical precedents that made us weary of leaders with nothing to challenge their power.
- better client displays (allowing a user client to switch out fonts based on the language, for example)

- better support for users who are not multi-lingual (a client could try to auto-translate sections that are not in the user's native language)

- better search capabilities (find me all documents that contain a French passage)

- better voice-assistant support (if a document is being read out loud for any reason, it would be nice to be able to handle multiple languages well. This also combines with the auto-translate capabilities above.)

Basically, all of the reasons why Gemini includes a "lang" attribute in the first place, except recognizing that parsers and clients want to be able to make use of that on a section-by-section basis rather than purely at the document level.

Sometimes documents are big and expand across multiple languages. It's just a bad abstraction in general to assume that each document would only have one language type[0]. Documents/books in the real world don't work that way, and a document format that can't accurately represent a giant portion of classic literature isn't a very good general-purpose format.

[0]: yes, technically Gemini allows you to specify multiple top-level languages, but that's not useful for anything. If I'm parsing a document, I don't want it to tell me "hey, there's some French in here somewhere, good luck!" Tell me where it is.
