IB claimed to have hiked margin to 100% which is a reasonable response. However, I have heard from many sources that they in fact rejected buy orders even with cash - which, if true, and I have every reason to believe so, makes any explanation about margins and technical reasons seem ridiculous.

There is surely some deeper non public reason that every single retail broker - but no single institutional broker - stopped accepting GME buys but kept honoring sells. It might or might not be a call from hedge fund buddies, but it is still likely illegal.

When I was working at a hedge fund, I once executed a few hundred mil notional on a supposedly anonymous exchange, taking advantage of an obvious counterparty mistake.

Within 10 minutes, I got a call from said counterparty, telling me that next time I do that, they’ll make sure I’m kicked off the exchange.

Anonymous my ass. Legal my ass. And yet, it happened - I’m sure I wasn’t the first or the last - the other side kept making those mistakes. I stopped taking advantage of them. This kind of behavior is rampant in Wall Street. Only difference is it has been done now in the open, very visibly, and with thousands - perhaps tens of thousands - identifiable victims.
I said small country in the original post, because while I imagine the US has similar levels of dynastic cliquey stuff going on, it's a colossal nation, so it doesn't hurt so much.

In the UK, I think Eton is more a symptom than a cause. The problem is, London is a world-class city that concentrates the entire political and financial establishment. It's also a city with very obvious parallel worlds, where if you move in certain circles, you meet the same people, so while it is a massive city, it sometimes feels quite small.

To me, the worst part is not that both Johnson and Cameron went to the same school, the same university, or even the same exclusive dining club - the bad bit is that because any given person with political, social or economic power in the UK is so closely connected with any other, there's a real incentive not to rock the boat. You get an enormous amount of cohesion, because if you go around making enemies, you're ultimately making things awkward for a lot of your friends and acquaintances.

On top of that, the fact most people in this world have similar backgrounds makes a lot of them 'on the same page' by default.
Makes sense, that's what I've seen other folks do. I'm curious if you've seen them ask for more features over time, more actions, ability to manage the rules they write - and whether the full blown version of what they need was easy to support?
There always seems to be buyers for more exotic high end hardware. That market has been shrinking and expanding, well since the first computer, as mainstream machines become more capable and people discover more uses for large coherent machines.

But users of 16 socket machines, will just step down to 4 socket epyc machines with 512 cores (or whatever). And someone else will realize that moving their "web scale" cluster from 5k machines, down to a single machine with 16 sockets results in lower latency and less cost. (or whatever).
...yes, that is my point. Anyone who deals with crypto is aware of it.
And, AFAIK, the police themselves CANNOT GRANT IMMUNITY. Only the prosecutor can sign an immunity deal with you. By the time you are talking to a prosecutor, you should have your lawyer involved.
Is there an equivalent to short selling for physical goods? Does the question even make sense?

If you though gold was overpriced (and there was no gold futures you could short) what would you do? Buy silver? I guess you invent a short by entering a contract to sell someone gold 6 months from now for a given price. But short of inventing a means to short-sell, what would you do?
The news doesn't have experts in securities tradings law, and it's still not clear what happened.

What's going on right now is unprecedented, so it has to go through a complex review process. Just following the news is witch hunting.
Have your attorney ask for immunity and confirm to you that it’s then safe to talk with police (your attorney will just say, “No!!!!” when you ask them)
Thanks for looking! my personal blog is not a place I was planning on implementing them just because it's not somewhere I do a lot of development. The landing page does use feature flags but they are handled on the server.

Honestly one of the next features I have on the roadmap is to hide certain feature flags from the UI. There are a lot of teams that would like to keep even the name of a feature private.
Robinhood is not Melvin, different companies have different net asset based and borrowing ability.

Melvin was also bailed out by Stephen Cohen, who the Melvin founder worked for. Cohen likely believed in the founder and already knew enough about their positions to be able to make such a huge investment in such a short time frame.

Equity investments typically take too much time to complete due diligence when your firm is drowning in a hurricane. Robinhood was rumored to have tapped all their available credit lines for $1B before they ran out of cash. I suspect we will read about an equity infusion in the next few weeks, if they make it that long.
Ok, so let's take an example. In a very hand-wavy way, the ZeroMQ messaging queue works without a central messaging broker or service, but purely as a library. In theory, you can implement ZMQ messaging primitives in your language of choice, but this is a lot of work, so it is usually used through bindings to libzmq C library.

I don't know exactly how it works, but at some point it writes things to some memory address. This is the point where the Rust compiler starts complaining about the situation if you try to use the bindings from something that can potentially be sent between threads. So you use some mutex, or a lock, and maybe wrap the whole thing in an atomic reference counted entity.

What would be the Pony way of solving a situation like this? It does say that it is possible to directly call C or C++ libraries.

I'd really appreciate if someone from the Pony community can elaborate a bit on such use cases.

I don't know much about WSL, but the instructions for this do not look right. Isn't WSL usually just a Linux distribution, so you should also use the package manager?

If you just run ./configure && make && sudo make install, sudo will be installed to /usr/local as prefix. Doesn't this mean the unpatched binary at /usr/bin/sudoedit will still be accessible?
Dev recruitment is hard to find php developers? wtf are you smoking? I think a lot of this is highly dependent on where you are. My guess is you mostly deal with non php languages?
Fullstack (But Mostly Back End) Developper; TypeScript / Nextjs
We are building a bank application with current & saving accounts, money management, wire transfers, and card management. We are launching on the French market at the start but the next step is to go global. Draft here : https://green-got.com/

The endgame is to offer a solution that will reduce the carbon footprint of our clients by redirecting their money from carbon-heavy positions to eco-friendly ones AND to provide a better banking experience.

We are building a NextJS API and static front end and react native applications. The NextJS backend is mostly a proxy to our providers for banking and money management services. Connecting our backend and those services, and test that connection would be your most important task.

You have worked for at least a couple of years with TypeScript on the backend. You know how to write clean and well tested code. You want to make all your code dead simple to read. Experience with the banking or payment industry is a big plus. You don't need to be a degrowther vegan but you must have a certain sensitivity to climate issues.

You can work from wherever you want, when you want, as long as you deliver. We intend to build a long-term relationship with our employees. So, the best candidate would be a french national that we can hire under french law for long term contracts. But we are open to international candidates on a C2C invoicing relationship. Being not too far from Paris time is a plus.

The budget for this position is 3500 euros per month, 42000 euros per year ($51k). The end net salary will depend on the country you live in.

To apply, see the exercise here : https://github.com/green-got/exercise
Having received a flu shot is a discrete measure. What we care about at the individual level is their response to that shot, which is continuous, minimally something like P(got-flu | got-flu-shot). What we care about at the population level is the probability that someone actually got the shot given that the records says that they did and the probability that they did get a flu shot given that the records say they didn't or that the records are absent.

The conceptual data model for vaccination in the US is a table with ~370 million rows and a column for each vaccine with the type being the date the individual last received that vaccine or a null. It is nearly impossible to construct this table with any reasonable level of data quality.

Even measurements of height are subject to error. The question is whether the error is larger than the level required for some particular use case. Thus it is not that height is somehow more discrete (height varies over the course of the day due to gravity), it is that our uses for it aren't affected by the very low uncertainty that its measurements entail. However, if you are building a spacesuit for someone and use a measurement of height taken at the end of the day in a gravitation field, they will be extremely uncomfortable when they get taller in space.

Thus even when there are measurements which are nominally discrete, if the uncertainty is greater than that of the use case, then the fact that it is nominally discrete doesn't matter.
Fellowship also has a specific meaning in Middle Earth, but that doesn't mean that it must match coincide with every other application of the word.

Words can have multiple meanings; sometimes troublesome ones (i.e. 'tabling' an item on the agenda).
Thats optimized for never having to renumber yoir lists as you edit your document.

I would hate to have to change 30 numbers because i want to move an item from last to first.
Performant is such a terrible word, one of those marketing neologisms that’s somehow made it’s way past the technical barrier. We’ve had better words for generations.
Oh wow! Cant wait to hear more about it.
You realize over 70m people in the US are obese right and another 100m are overweight? Known vulnerable groups include 170m people right there. I can't take your argument seriously.
And if I'm not mistaken, can't the cops even testify about how you reacted to this kind of BS in your trial?

"I told him the victim's blood was found on his pillow, and he barely even flinched. This guy was really cold-blooded."
To be fair, solving a great many murders is probably a simple matter of finding the family member with literal blood on his hands and a history of domestic abuse. It doesn't take Sherlock Holmes to figure that out.
I would bet a steak dinner that someone in Wall Street has built something similar to this to "front run" the WSB horde...
Oh interesting, will look into that! Excel works for one-offs, but with repeated queries, or if they're exploring data that they don't know exactly how they'd use, or if they want to affect changes in a system ("send email to all these customer ids"), they'd still have to come back to me?
I don't think this offering intersects with Middle Earth.
> They might still search, but now their search is without probable cause _and_ your consent, which means even if they _do_ find drugs in your car, your lawyer will be able to spring you easily.

There's an old saying: "you may beat the rap, but you can't beat the ride."

I'd just like to point out that the ability to recover quickly and easily after being wrongfully arrested is a privilege. If you are e.g. driving to a job that you can't afford to lose, it may be that avoiding a night in jail for a wrongful arrest is more important than your eventual principled triumph over the system.

Especially given that neither is guaranteed. Maybe the cop decides you're not worth the trouble and lets you go. Maybe they plant drugs and lie that you did consent to a search, and a jury believes them. Maybe your overworked public defender advises you to just take a plea. There are no silver bullets here, and the most likely bad outcome is entirely situational.
I can, but it will be basic! I might have to use a JSON file for the backend because I probably can't remember any database libs well enough to use without documentation.

However, lots of programming is much closer to plumming than to.. programming.. any time you're using a lib or api, you're just looking up what kind of fittings that comes with and what length of pipe to attach to it.. So don't worry about not being able to do anything really useful without looking in the docs :)

Now, if you have to look up basic language syntax for the language you use every day, I'd say its bad and you probably need to practice a bit ^_^

> This is extremely specific to jurisdiction;

In the US, a person’s rights are NOT specific with regard to jurisdiction.

One’s rights are enshrined in what are colloquially referred to as Miranda Rights (issued as a Miranda Warning upon arrest) and they protect all people detained by the police in the US. [0]

> You have the right to remain silent and refuse to answer questions.

> Anything you say may be used against you in a court of law.
You have the right to consult an attorney before speaking to the police and to have an attorney present during questioning now or in the future.

> If you cannot afford an attorney, one will be appointed for you before any questioning if you wish.

> If you decide to answer questions now without an attorney present, you will still have the right to stop answering at any time until you talk to an attorney.

> Knowing and understanding your rights as I have explained them to you, are you willing to answer my questions without an attorney present? [1]

That makes sense. But to be honest, if a police officer insist on questioning me despite my initially refusing to answer, I'd just ask for a lawyer.

I won't trust myself to handle legal processes, and I certainly won't be able tell if the police had forged a document for me to sign.
It is almost 'insulting' to the scientist community, greedy investors pitching their business as fellowship should be ashamed.

>> There is no upside to allowing them in

> I get what you are saying, and agree with your decision to not talk to the police

They DID talk to the police. (They said, "We'll answer any questions here")

Bringing them inside your home really doesn't have an upside. I don't invite armed strangers inside my home as a rule, and making an exception is unnecessary.
Matt Levine's article today [1] has a table of the retail flows, according to the underlying broker that handles most of them.

To summarize: between Monday and Thursday, retail investors bought 74,385,426 shares of GME and sold 75,105,358 shares (or slightly more than they bought). That really runs counter to the theory that retail investors are holding all the shares while the shorters are scrambling to find them.

They didn't write the runtime, they just modified a (relatively) small piece of it. From the article:

> JetBrains forked the OpenJDK project in order to facilitate better control over how the IDEs looked on Macs a well as other HiDPI screens; JetBrains Runtime was born and we bundled it with our IDEs from 2014.

> There are many facets of the runtime, and we do not know every little crevice of it, rather we focus on the part of the code that handles the rendering of UI on screens.
“Dumb money” is a particularly poor bit of jargon but as it’s used in finance it doesn’t really mean that the finance sector thinks a person is a rube or stupid.

It really means you think an order doesn’t imply any directionality in the order book. Most orders don’t! Most orders happen because of things outside of the markets (I’ve retired, I’m rebalancing my portfolio, my kid is going to school, I got paid so I’m buying into my retirement fund).

Those orders are not indicators that the market is going to move. This is in contrast to a hedge fund unrolling their position. That act will impact the market.

So for instance while Melvin was taking a bath closing out their shorts they were “smart”. But my index fund sell that made me money was “dumb”.
Police have even pretended to be the accused's attorney-- not lawful-- but generally the only consequence of an unlawful interrogation technique is that they lose the conviction.

( https://reason.com/2011/03/08/tennessee-cops-posed-as-a-defe... in this case, the trial court even allowed it-- it had to get overturned on appeal )

There is a whole subreddit (/r/legaladvice) where the moderators are all (almost all?) law enforcement officers, where they remove good information from actual attorneys and promote bogus "cop law" that is highly detrimental to the interests of the users.
Something that has dramatically reduced my reliance on outside resources is an editor that can lookup symbol definitions.

I’m using Django and I used to use Sublime Text without any plugins which meant (at the time) it couldn’t automatically show me the definition of a function or object from a library, forcing me to search around for its documentation.

Switching to PyCharm/IntelliJ meant I could now just Command-Click (Ctrl-Click for Linux & Windows I believe) and see the actual definition and logic of the underlying function without having to rely on the online documentation. This of course works recursively, so I can repeat this process again and again up until I eventually reach the core standard library which is in C and isn’t introspective (at this point I can rely on my knowledge or some trial and error to figure out its behavior).
I don't think the SEC should shut them down.

I think they should go bankrupt because their customers leave them for one of their many more reliable and trustworthy competitors.
AZis only obliged to deliver to hubs in each member state. That's it, nothing else. Hubs have to take the delivery within 5 days of being notofied of that delivery. That's about it regarding actual deliveries. Pretty thin, especially compared to the 4 pages covering the order form.
>Also N95s have to be fit tested to be effective. So randos buying N95s and wearing them will frequently not work.

I don't think this is true. No box of 3M N95 masks I've ever bought has said anywhere "failure to fit test this mask renders it ineffective." 3M Aura masks have an instruction video on how to maximize the fit, but thats just a bit on how best to adjust the little metal bit that clamps around the nose.

An ill-fit N95 that might not be perfectly adjusted to conform is still way better than a cloth mask which isn't intended to seal at all.
The point is that money would not be lent, but invested. A moral alternative.
One possible problem is that generational earnings are a function of economic conditions. These may average out over a lifetime, but if we look at restricted intervals, it may seem like newer generations have less wealth even if they end up having similar overall wealth over their lifetime.

Leaving out boomer data from ~18-35 makes me a little more suspicious of cherry picking because that data could be similar. It may also show boomers gaining even more wealth, but if it's not available we can't know.
When I bought a bunch of NVME drives, I was disappointed with how slow the maximum speed I could achieve with them was given my knowledge and available time at the time. Thanks for making this post to give me more points of insight into the problem.

I'm on the same page with your thesis that "hardware is fast and clusters are usually overkill," and disk I/O was a piece that I hadn't really figured out yet despite making great strides in the software engineering side of things. I'm trying to make a startup this year and disk I/O will actually be a huge factor in how far I can scale without bursting costs for my application. Good stuff!
To add to what you said, every time I have bought furniture from someone other than IKEA that needs to be assembled, I've missed IKEA's clear instructions.

macOS doesn't have sudoedit, but you can make a symlink to it, as sudo is effectively a multi-call binary:

ln -s `which sudo` sudoedit

and then call it:

./sudoedit

So don't take the lack of a `sudoedit` command as evidence that a system isn't vulnerable. I don't know if the sudo included with macOS has been exploited though.
It is purely a research idea at this stage and would benefit from a program purpose built for research. If it wouldn't be a good fit because of your life science focus would you know of any similar programs for CS oriented ideas?

Censorship is not and never can be a solution to the issue of misinformation. At best it can hide the problem as people are forced to take their wrongthink underground, but there it festers and no one can effectively root it out.

No the only way to deal with incorrect information is correct information. You can't suppress the argument, you need to win the argument. People need to be taught how to think critically and evaluate various conflicting sources of information, we must go out of our way to present information showing our positions to be true and call out even those we want to agree with when they don't, and we must take the high road and maintain composure even when others do not act in good faith. Yes, it's exhausting, but no one ever said doing the right thing is always easy.
I totally agree with this. It's quite annoying you never quite know what dialect some website is using, they never mention, because it seems very few of these dialects have names.

What also annoys me is that they didn't base it off Wiki formatting. It would've been great if it had at least some compatibility for basic stuff like headings and links.
No, it is whole new machines for everything. None of the processes are similar. There are attempts to make something like the flu shot than others could make, but those are not approved in the US (yet).

Note, since my reply I've discovered the J&J has in fact released results at 72%. too late to edit my post, but I will stand corrected when called out on that. At 72% the mRNA at 95% is much better, but J%J can make a lot more vaccine so I'll take what I can get.
