Similar explanation was posted Jan 28 on twitter by Silent Cal[1]. This article and the twitter thread do paint a very plausible explanation. And is easy to accept.

OTOH, a potentially far more nefarious, yet plausible, underlying motive was posted on /r/wsb today [2] that links GME to counterfeiting shorts.

Given Steve Cohen's numerous scandals through the years as detailed on wikipedia [3], needing to cover up for counterfeiting shorts also seems like a plausible explanation.

I hope the finance committee investigations AOC called for take place and consider both points.

Corporations love regulations. Let’s remember this when we support things like net neutrality. They always try and sneak regulatory burden in any of these bills.
The question isn't whether it is possible to write shitty code in a given language. Every language can be used to write shitty code.

The issue is, given a person that knows the language does not know how to structure their code, what is likely going to be the outcome with regards to maintainability.

My production experience is mostly with C, C++, Python and Java.

As an example, consider typical Java backend application. Even novice developers would typically learn Spring and create applications that contain controllers, views, repositories, services, etc.

They (I mean novice developers) would be constantly repeating rules they don't know why they are following, but heard it is important or seen it as popular. So maybe things like you should have your objects accept injected dependencies.

It does not mean they will know how to use these or even that they will use these productively to create more readable code, but what this does is creates code that has at least some structure.

The code might have huge amount of duplication and redundant or unnecessary constructs, but you will be able to move around, understand what you are looking at (okay, this is controller so I know how this most likely works, this is database layer so I know what I can expect, etc.)

On the other hand Clojure imposes exactly ZERO structure on your application. That is powerful but only if you know how to structure the application yourself, know what kind of choices you need to make and know ins and outs of various options.

If you have no experience creating structure, have been Java dev all your life and have always relied on structure that was given to you and never thought about it until today, you are likely to produce absolutely unmaintainable mess that nobody is going to be able to figure out.
Absolutely. Just imagine the inverse scenario here where they had a conflict of interest in a long position and turned off selling. Turning off both is fine if they’re not able to legally handle new buys. But just turning off buys is also pretty freaking sus.
Years ago I turned a decommissioned server into my desktop (when 4gb was a lot of memory). Worked fine, but when I switched to a laptop as primary and turned it off I think my power bill dropped by $20-30/month.

If I'd checked the draw earlier I'd have killed it far sooner.
Just commit the work to the public domain then.

>AZ is doing this for non-profit (a big mistake in my opinion)

Oh wow. I haven't been following closely. But Why? They should have made at least some profits. And use those for R&D.

And if it was done for Non-Profits, why did it take the EU another 3 Months to put a stamp on it?

And honestly it is very common to have Supply from different site for different region for all sort of reason. Transportation cost, safety, Time to Delivery etc. If everything you said were true ( and I dont have time to Fact Check everything ), then EU has only themselves to blame.
The purpose of a clearinghouse is to manage that counterparty risk prior to settlement, and ensure that settlement occurs smoothly. Some clearinghouses like OCC carry counterparty risk throughout the life of a trade.

The counterparty in question is the clearing member, ie Robinhood. If the trade is fully cash-secured then there is no risk that Robinhood will go under because it has 100% of the cash required to make good on the trade (assuming they still make enough from PFOF to cover their operating costs for a couple of days.) And for existing margin accounts, they just have to continue the practice of aggressively closing positions that fall below maintenance margin.
> Why?

Because it allows for more internal netting, and more time to reconcile discrepancies with the tape.

If you're familiar with computers, it's the same kind of tradeoffs as doing lots of rpcs vs. batching.
Never ceases to amaze me Ayn Rand resorted to receive social security benefits when she was old and broke, fact which makes her philosophy all the weaker. People need a safety net because unpredictible things happen that are beyond control.
What's scary is we now have whole entire generations of Americans who have never personally witnessed a functioning housing market, and this is the kind of junk they believe.
That's terrifying. The trial we were in used esketamine dosed via inhalation. You could not take any of it home and the doctors controlled all doses.

I'd be suspicious of those who wanted more and more of the drug. It made her so dizzy and sick there's no way she'd want more.

I almost wonder if you can detect who is abusing it by how much they enjoy it...
This was a good test to catch those HN members who don't bother to read the article but decide to argue with the headline.
> This too smells fishy and rigged to me. Modern databases don't need T+2 to achieve consistency.

The problem is, you have lots and lots of databases-- there's not one central ledger of every position. Settlement is effectively an atomic commitment protocol, so that if you are selling a stock you expect to receive from one firm to another, and someone else fails to deliver, you need to be able to unwind the downstream trades-- but also need all transactions to eventually become final.

The T+1, T+2, T+3 periods are convenient in human units, because sometimes it's desirable to have a human in the loop when unexpected things happen.
We are agreeing that NYC is not at a moment of urban collapse. The processes that drives away the tax base includes policies and social and market forces that erode the city's effectiveness as a sustaining economic and social hub.

The 1960s and 1970s crisis had a lot to do with the end of NYC's industrial epoch. Suburban development and globalization eliminated manufacturing and pulled workers and residents out of the city. The recovery of NYC was bringing high-value services, retail, and tourism back along with arts and culture.

In the time since, NYC has become increasingly a luxury experience, which is indeed part of its strength but also its weakness, since it accelerates decline when people can up and leave without having roots.

The scope operator is an ugly opt-in mechanism you will only use if you discover the problem.
More to the point... why didn’t Robin Hood simply make the buys in those tickers REAL buys instead of margin buys and explain the situation?
Last summer some time, I was coming down from mushrooms walking home down a road that, when I was a teenager, had been forest.

I became really aware of the streetlights trying to look at the stars going down the road.

You used to be able to see so many stars from that road before street lights or houses were put in. So many stars it was hard to see the space between them.

When I got home, I ended up lying on the grass for a bit in the dark to try and look at some stars the street lights ended a couple of blocks away, so the yard's still relatively dark at night.

Then when I looked up and tried to watch the stars...all I saw were satellites zipping around everywhere.

When I was a kid, seeing a satellite was a fairly rare phenomenon almost as exciting as seeing a meteor. I honestly found the satellites to be more depressing than the light pollution. There wasn't a section of sky that didn't have a satellite in it.

I was still somewhat in that mushroom state of mind, so I got kind of unreasonably sad about it. But it really bothered me. I ended up not wanting to look at the stars and just went to bed.
I was definitely not expecting user feedback to go in as GitHub issues. I should have been more clear of what I was expecting.

Incompetence is a source of extreme inefficiency in modern society. People making decisions don't understand the things they're deciding. This is broken. And there's nobody sane in a position where they can say "STOP, this is dumb" and demote people to the level of their competence or fire them.

A harmless example is movie / tv show plots not making sense - there's nobody willing to call out bullshit like obvious plot holes. This is how GoT went from a masterpiece of scheming characters driven by their motivation, making decisions based on information they had and dealing with the consequences to "she kinda forgot".

A dangerous example is the government being full of people who are too incompetent, stupid or useless to get a real job. Sometimes the number of them in the system is so large that competent people can't get anything done to fix things.

We need to do something to fix this. Positions of decision making power should require an IQ and/or knowledge test.
From this article, "motivational interviewing" is supported by actual research.

That's a nice change.

My people on the left keep doing the "fat shaming" equivalent (scolding) for politics and policy. Stubbornly wrong.

Most of the advice about debating and persuasion is worse than wrong. This article calls out the "backfire" effect.

I was one of them. I eventually figured out it doesn't work. I've been trying to find and learn better strategies.

I've tried to apply lessons learned from Camp Wellstone, Prof David Domke, http://www.heroesnarrative.org. (I even study people from the other side, like Frank Luntz, Ben Shapiro, Grover Norquist. Know they enemy and all that.)

I'm also very impressed by ideas from deradicalization, cult deprogramming, Chris Voss' (hostage negotiator) "radical empathy" and others. Guarded optimism that this stuff will help.

I'm just so sick of the food fight. Alas, there's still real work that needs to be done. And I'm forever trying to figure out how to sneak progress thru the chaos of war.
If a broker blocks selling, and the price drops, there is real damage to the holder of the shares. If they block buying, there is only a potential hypothetical loss.

In that debate, we quite often hear something along the lines of "I can't remember the last time a static typechecker actually helped me" and that makes me imagine a fish saying they can't remember the last time that water actually helped them. Maybe the ambient help is so constant that it no longer even registers in long-term memory.
The same way they felt safe after Sun won over Microsoft.
From understanding the issue is that RH didn't have enough collateral to execute buys. If they restricted sell on RH in the name of symmetry, but other broker with no collateral issue would still allow buy and sell the stock would remain volatile. In this case, not being able to buy is a nuisance, but won't make you loose money directly. Not being able to cash out in the event of a steep decline on the other is directly and highly prejudicial.

I understand that restricting buys affect the price for those who already bought in, but at least they can still cash out..

It’s shortened over time, but things across many parties still need to be sorted out, including buffets for fraud. Visa also doesn’t work the way you think it does, much like checks, ACH transfers, and wires also take days to clear.

There are at least 2 generations of the motherboard, make sure you get the second (z620). Also if it still has the original workstation Nvidia card, toss it and replace it.

I sympathise with her as a person. She went through a lot of trials and difficulties during her life. But to deny that other people matter in our lives is a strange stance. I decided that I don't want to go there. My work is to benefit humanity, little though it might be.
"Corporate publications are more trustworthy..."? My brief exposure to that arena would lead me to disagree strongly (but I am an engineer and not in marketing). Everything in my experience has to be vetted by multiple layers of the organization or at least people versed in the art of saying something while actually saying nothing. "Corporate publications" is a very broad term, of course, so it depends - financial type things, yes, that has to be pretty 'solid' though there is still room to elide and be disingenuous. Whitepapers are essentially just marketing material; being an engineer and thinking like one is really detrimental, thus I just couldn't do that sort of stuff... And some subset of shareholders will always try to interpret <whatever> is any number of ways, so that is another reason to spin things as needed while not seeming to spin things.

Wikipedia has a pretty robust set of internal controls and correction policies IMO. It may not be authoritative, but it tends to be a good starting point, unless the topic is obscure etc. My brief exposure to higher education would be that yeah you don't want to let students treat Wikipedia as a primary/only source (the lazy ones have that attitude), but I wouldn't go so far as 'not reliable'.

The fundamental issue is ho do you teach people/children to synthesize different sets of information and decide what is useful and what isn't - i.e. to think for themselves? Part of that effort is also teaching them to be self aware enough to understand how their emotions or emotional issues might color their interpretation of the information, never mind evaluating the source of information first...

A lot of parents think it is a really bad idea, teaching children to think for themselves and to be self-aware...
You're expecting a basic level of competence and maturity that RH doesn't have as evidenced by past problems.
I would say this is exactly how I was able to pivot out of web and database development into VR development[0]. I spent a lot of time going out to meetups when I first started getting into VR. Meeting people, talking to people. Eventually, I started showing people the stuff I was building. That led to getting asked to do talks at the meetups about the stuff I was building. That led to more contacts. I ended up making friends with folks who would
one day make the connections that got me my current job.

Incidentally, when folks at my current employer started talking about hiring someone for my role, they kept running into people who knew me and had a high opinion of me.

Networking works in many directions. But it only works if you don't go into it looking for it to work. I think the big key was that I wasn't out to gladhand with folks. I was just out to make friends over a shared passion. It gives an authenticity to your speech that people can see.

[0] Which now has a big web and database component, all in service to the VR app that I'm building.
The problem with this theory is that it wasn’t just Robinhood. There were literally like a dozen or so firms that halted buying. Some of which were well known long established firms (Merrill, etrade).

These firms should have had no problem continuing allowing purchasing.

I haven’t done it in years, but with some hacking early versions of clang could totally compile blender and that’s quite amiable to benchmarking (maybe too much?).
I spent a lot of time thinking about this.

What makes Perl or Clojure such fun languages to work with is they don't impose structure on you. You can do whatever the hell you want.

On the other hand result of this is the code represents basically how you think about the problem. Which would be very different for every person.

Languages with frameworks like Java+Spring, Ruby+Rails etc. are less "fun" to work with because you are not given so much freedom and likely have to fill in a lot of stupid, mundane boilerplate, but are easier to maintain in team setting because developers know more or less what to expect from the code. Very likely developers come with that knowledge and if you know one Spring application you know how to move around almost any Spring application.
It would be interesting for GitHub because they have a large developer community who push to these app stores already, so they have the dev audience, just not the consumer.

They charge said developers a few dollars a month per seat. GitHub could somehow instead be taking a 0%-20% cut topline revenue from some of the apps they host.

Lots of work to make that happen the upside might make it worth while.
Tool, not site. However, let me try to add a little value: if, like me, you didn’t know the IETF’s site offered a tool for web-friendly RFC viewing, check out the full (maybe?) list of their tools. Some of the links don’t work or are insecure, but there are some neat scripts available, too[0].

Linking urls and cross-referenced articles is why I prefer sites like man7[1], for online command reference.

A nice fuzzy RD design! The interpretation of their results, though, is difficult because the counterfactual is not very clear to me.

They are using admission score cutoffs to oversubscribed vocational schools. The intuition here is that people who score right below and right above the admission cutoff did so because of randomness, therefore their setup approximates a random assignment experiment at the cutoff.

For the results to be interpretable, we need to think through the counterfactual. That is, what happens to the students who score below the cutoff and that are not admitted to those over-subscribed vocational schools? Do they complete a general education degree at another school? Do they attend another non-over-subscribed vocational school? Do they drop out of school altogether?

I am curios about reduced form estimates of the gap (i.e., without the 2-stage estimates). I wonder how much of the $2000 could be explained by more experience on the job for people who complete a vocational track rather than a general education track+university. In that, I wonder how much of a delay entry to the job market could explain the returns of vocational education.

Another thing that I am wondering about is how elastic to education/credentials is the Finnish labor market. That is, how responsive are wages to credentials/higher education degrees. I hope that the actual articles/publication includes a description of this because it will be important for external validity of these results beyond that specific national market. For example, in the United States, there is a big wage gap between professional degrees (e.g., medical doctor, ~$120.000 year) and vocational degrees (e.g., welder, ~$40.000 year). I wonder if the same large gap in wages is present in the Finland. If that is not the case, I wonder how much these results would apply to other non-Finnish job markets.

I'm also not sure if I buy the authors' claim that "The regression discontinuity design estimates come from the middle of the distribution of academic ability. However, the benefits may be even larger for people with low compulsory-school GPAs who only apply to the vocational track, while vocational education may be detrimental for people with high GPAs who apply only to the general track." This feels like a misrepresentation of the RD estimate. They only estimate the effect for people who score right around the cutoff. They cannot really extrapolate the effects beyond a small bandwidth around that cutoff. They are really overselling their results when they discuss people away from their cutoff and just guessing what would happen to people at other parts of the distribution.
It may well be that it does take payment processors t+2 days but I think the point remains that it should not.
Was the buy limit only for GME or all stocks on RobinHood?

If it's the former, how does the article's explanation fits?
> Outside of scientific reasoning, "theory" and "hypothesis" are often used interchangeably, and "theory' can unfortunately be interpreted to mean "less sound" or "lightly speculated."
T+2 is not a database limitation, it’s a deliberate decision by clearing houses to provide a window for cancelling a trade in case there are problems - fraud, etc.
