>Maybe assholes shouldn't be able to use these platforms to shape public opinion and influence elections and news

And who judges who is the asshole objectively?

For example, in my book a president who actively bombed 7 countries, continued wars he was elected to stop, under whose terms ICE deported more people at the border than Trump (wall or no wall), gave Wall Street a "too big to fail" bailout, enlarged surveillance and hunted several whistleblowers and threatened journalists, is more of an asshole (and a danger) than another who is just a crass business/tv personality that wrote mean tweets and that rednecks liked. That's whether the former has had more political experience or is a smoother talker, and polite company.

But that's just me, and neither is even my President, so...

>Maybe having a Twitter account is a privilege, and not a right, and that privilege is correctly granted on the precondition that one will not act like an asshole.

No, I'd say that having an account to social platforms above some population reach level shouldn't be a "privilege" but a right (that is, subject to due process/law, not up to the whims of the company).

Else, those who control said platforms (where the majority of the public frequents and where most of public discourse happens), also control the public dialogue.
Surely this is only a problem if customer's dont have the cash. Eg I can imagine if people were funding their account with ACH or credit card payments it takes weeks to clear. It makes sense that RH would ban these from buying GME. But if you have cleared cash in your account I still dont see the cash crunch.

The first one looks like a form letter that they had on deck for "we need to stop trading right now" situations and they just plugged in the list of symbols. The second one is the more adequate explanation for when there was time to get actual humans involved.
Thanks for that. It seems like a mild and practical fiction. Most the time it seems to just work with reduced friction.

Correct. If you are in Australia, file a complaint and then escalate to AFCA. This violates the Market Integrity rules which applies to IBKR Australia.

Please, some common sense. Google is one of the wealthist and powerful companies in the world. RH is one app out of millions in their play store. No one at Google is stupid enough to do RH a favor. It's not the first time nor the last time they do something like like this. Their tos doesn't allow rating manipulation, which clearly happened here. They don't care if it justified or not.

It doesn't cost them any money to close the position, so the cash crunch doesn't apply.
Then both ideas are terrible and they should have done neither of them.
Not sure why they stopped at 2018. They've gone down a lot more since then.
That's not really how streaming works. The streamers generally don't pay per stream, they pay a fixed cost for a fixed amount of time of unlimited streams. At the same time, if a user is streaming or not is negligible cost. They build the infrastructure assuming everyone will stream, because unlike a gym, most people drop the service if they don't use it.
I think you’re right, but unless you have insider knowledge that would move the stock, is trading in blackout a legal or corporate violation?
Yet interest rates have yet to respond (unless I have missed some major news). You are correct to point out the risk, but I don't think we can call it currency debasement yet.
Any papers showing actual clinical trials of this thing?

I ask because the word "clinical", used repeatedly in the article, means... in a clinic. And devices like this have an unfortunate habit of failing to perform in the real world.
On an individual basis yes you can make that argument. On the basis of market manipulation, it is very powerful to reduce the demand side by over 50%, while keeping the market open so that other people who want to buy at a lower price can do so. This is what happened. Don’t gaslight yourself.
I can accept that they ran out of cash. It's just like a company running out of servers when traffic spiked. On the other hand, moralizing their decision and citing misinformation and user-caring erodes trust.
It seems like maybe the solution is not to remove reviews, but weight them somehow. 100k reviews left in 2 days probably shouldn't have the same weight as 100k reviews left over 2 years.

Or a more sophisticated version of this would be to somehow cluster reviews based on the particular issue they are reporting.
Rates can never rise. Americans and American corporations are too indebted with no room to finance increased debt servicing costs. The dilemma is the longer rates stay low, the more debt is piled on. Ultimately there must be a complete reset.
I've heard it said that Americans all think they are potential millionaires and billionaires that have temporarily hit a down patch. That's why democratic socialism will never fly here except for isolated programs.

I don't understand how it's 'failed' - it is an iconic building. I wish I was able to afford to live there.
It's somewhat surprising because the recognition of "risk" as a concept is much more recent, and its relation to finance and rates much more recent than that. If the relation between risk and rates of return has held for longer than that, then it means that it's an emergent phenomenon of markets without anyone actually using it as an intentional strategy.
There were allegations RH did a large sell-off today of client's margin positions today presumably in order meet collateral requirements. It's possible they realised it'd really not be in their client's interest to telegraph that ahead of time.
My understanding of this paper (please comment/correct based on your understanding):

* Instead of using a single latent feature per each implicit surface, the authors propose using a "volume" of latent features per each surface. This allows for the NNs to better capture the geometric detail while remaining relatively shallow. The result is a more accurate and faster to compute neural SDF. Contrary to the claim of another comment, the neural SDF alone is not the interesting part of this paper--the prior works points to at least three other papers that have explored the idea of representing an SDF with a neural net: Park et al.'s DeepSDF https://arxiv.org/pdf/1901.05103.pdf, Mescheder et al's Occupancy Networks http://www.cvlibs.net/publications/Mescheder2019CVPR.pdf, and Chen et al's Learning Implicit Fields https://arxiv.org/pdf/1812.02822.pdf All very interesting papers.

* When I say a "volume" of latent features I specifically mean a voxel-grid where the corners of each voxel are latent features and any position X has a corresponding feature Z which is simply the trilinear interpolation of the features on the corners of the voxel. As the authors mention, they try to keep this sparse by leaving any voxel that does not contain the surface "empty".

The authors use an octree to create L different feature volumes. As L becomes larger, the resolution of the feature volume increases which means that more fine grained details can be encoded as features.

Finally, the authors describe a rendering procedure that makes use of their LOD model (still need to read this part more thoroughly).

Some additional thoughts:

Why are SDFs useful at all?

One comment suggests this is a form of "compression" but meshes have a far smaller memory footprint and are computationally less expensive to render. Ray tracing is extremely fast, largely due to the fact that as a primitive operation in graphics so much time and energy has been invested into understanding how to make it faster with various acceleration structures, like BVHs.

So are SDFs actually useful?

Yes. Triangle or polygon meshes are great when you have them, but are terribly challenging to work with for reconstruction tasks. For instance, you effectively have to pause occasionally during reconstruction to fix your mesh up so that it isn't complete garbage (triangles with small angles, self-intersections, extremely lopsided side lengths, etc). SDFs support arbitrary topology painlessly, which is why they show up so much in reconstruction/computer vision.

So why do we need neural nets to represent them?

I think the primary reason you use a neural network to represent a signed distance function is because it's a more efficient representation than storing the SDF in some sort of grid structure (maybe someone else has more thoughts on this?). As a side benefit, it can simplify any sort of differentiable rendering since the surface itself already is represented in a manner that is naturally differentiable via back-propagation.
Because they risk running of being short squeezed in those stocks as well? Last time I check, big money isn't exactly throwing itself at airlines, mobile areas other than Android or iOS, and cinemas, even though two of those are bound to pick up later this year once covid is over and Black Berry is in talks with Baidu, which you can't ignore.

The big guys know all this, only they were hoping to short, make a profit, and then reinvest down the road when things picked back up, making even more money. WSB just capitalized on their strategy and now that they are losing, they are throwing a fit.

The post above seems to talk about deflation.

It's possible we're just using a different sign convention (or perhaps I've missed something more fundamental)
I agree with the attitude of "if you want it, code it" however I disagree with this point. Gatekeeping does not have to be intentional for it to be the case. Sometimes it can be out of good-will, even.

For an example of the last point, transgender care in the UK -- it takes 2 appointments to get treated (hormone therapy), it can take up to 4+ years to get the first appointment (those are the smaller waiting lists), and another year or longer to get the second before you are finally treated for it. This isn't done out of bad-will, it is done out of intent to not mistreat people. However, the effect of this is that it gatekeeps people who can have access to trans care to those who are able to afford it.

Gatekeeping does not require intent, nor does it require malice. It can simply be the result of a cultural artifact creating what is percieved to be a hostile culture.
This is assuming that programmers from countries with lower salaries are less competent, which is not always the case. It's harder and harder for workers in the developed world to justify that they are more productive than others. For millions of smart people around the world the hurdle to a better life is just the right visa or residence permit.

We ban accounts that post like this. Please review https://news.ycombinator.com/newsguidelines.html and stick to the rules when posting to HN. You may not feel that you owe the person you're arguing with any better, but you definitely owe this community better—much better—if you're participating here.

Your account has already done this more than once, as well as posting unsubstantively and baitingly in other ways. That's a poor track record for only 11 comments. I don't want to ban you, so please fix this. On HN we want thoughtful, curious conversation. Bashing each other like this is obviously at the far extreme from that. No more of this, please.

Wait “most hedge funds are doing honest business”? Who are we talking about and what honest business is that? Front running trades while market-making, privatizing the profits and distributing the losses if they fail? Networking with other billionaires on insider information? They are parasitic opportunists.
Either way, this could've been an automated system kicking in, which probably cannot tell between legitimate and "illegitimate" review bombing.

TIL the "switch" keyword in C was originally a PDP-11 assembly helper subroutine in the Unix system library (this was written before the invention of C). It explains everything about C's behavior.

NAME switch -- switch on value

SYNOPSIS (switch value in r0)
jsr r5,switch;
swtab
(not—found return)

swtab: val1; lab1;

valn; labn
..; 0

DESCRIPTION switch compares the value of r0 against each
of the vali; if a match is found, control is
transferred to the corresponding lab. (after
popping the stack once). If no match has been
found by the time a null labi occurs, switch
returns.
Latency as a Forcing Function
> A substantial amount of trades in the market are executed by liquidity providers that provide efficient two-sided
markets. These important trading firms trade on both sides of the market and are largely risk flat at the end of the
day. Real-time settlement would require these liquidity providers to have significant sums of capital and securities
on hand to make trade-for-trade deliveries.
The current infrastructure relies on the efficiencies of trade netting to accommodate substantial amounts of trades.
Wholesale market-making is important to the infrastructure as it provides the capital and balance sheets to back
customer trading. Significantly increasing those capital requirements by requiring pre-funding of all trades without the
benefit of recognizing the offsetting trades would substantially increase the costs of trade execution to the end user.
Real-time settlement could also introduce operational inefficiencies. In a typical low-volatility trading day, NSCC
and DTC process over one million shares per second on average, valued at over $16 million. During peak trading
hours, such as market open and close, this number spikes to over 300 million shares per second, valued at over
$25 billion. Settling these amounts throughout the day in real-time would introduce substantial financial and
operational risks to the equity markets.
Accelerated settlement that abandons the significant capital and operational efficiencies gained through
centralized multilateral netting would be a step backward for the world’s most liquid markets. Striking a balance
between the capital efficiencies of netting and the risk mitigation benefits of moving settlement closer to trade date
should be the goal of the industry.

Thanks! Replacing market makers seems difficult.

God willed the Uighurs to have no option just as he willed your misguided reply to my comment. He also ironically willed me into becoming an atheist. Essentially, God is not only the dictator of humanity he is the dictator of reality as we know it.

You're ignorant. See sources below that claim god is basically king:

Need your feedback on our Online Shopping Assistant
Hello,

We are currently developing an online shopping assistant "DyNotify.com", it's a free browser extension that offers these features:

• Search: search, filter & switch results in dozens of e-commerce websites all in the same place.

• Track: Receive alerts on price changes & availability for any product.

• Alternatives: Get better & cheaper alternatives for specific products across all e-commerce sites.

• Recommendations: Discover new products, recent deals & top innovations from all sites in a curated list.

20-sec demo: https://bit.ly/3sYAgXr

The problem relies mainly on the search process when someone wants to buy something online. With the overwhelming number of websites to search for various products & services, and the challenge of keeping track of price changes, discounts & availability. It takes time and continuous effort to find the lowest price or the best deal across all sites, in addition to the fear of missing out on a deal that could've been known otherwise.

It's somewhat similar to Honey, but for alternatives instead of coupons.

If you shop online frequently, would this extension be something you may use or be interested in?
and from the features above (Search, Track, Alternatives & Recommendations) what brings more value and solves a problem for you?

Would love to get your feedback on it, thank you.
Only if the purchasing power of a dollar goes down. I know MMT is controversial, but I think of it more as a focus on empiricism.

Sure, rationality suggests that printing dollars will reduce the value of dollars. But kickstarting inflation is in some ways the entire point, no? And it has remained consistently below FR targets for the past decade (I believe, I'm not an economist and I'm not looking at any charts)
> to make sure money is there and no fraud

"make sure there is no fraud" takes a LOOOONG time.

It is the reason why a car bought from a dealer drives around without plates for a month. That's how long it takes the dealer to be totally sure the payment wasn't fraudulent.
"Morality police" was once a 80's or 90's trope or meme against the religious right coming from the left.
