> intent to manipulate the price (which IS illegal)

Is it "illegal price manipulation" even if it's done completely out in the open for everyone to see? (I'm seriously asking this question).

I feel like laws governing market manipulation imagine secret collusion among actors that one might reasonably assume are either competing with one another or pursuing their interests independently.

But in this case, the actors are entirely transparent with their motives. Anyone can go see what they're up to. Figuring out why these stocks suddenly went through the roof required no formal investigation at all, as far I know; it didn't take long to figure out why it was happening.

I also wonder whether those motives are even an issue here. Certain people in the system might be legally bound to be truthful with their clients, they might be required to pursue their clients' interests faithfully, and so forth. But isn't it true that as an individual investor, I am perfectly free to invest in stocks based on my horoscope, my initials, random throws at a dartboard, or anything else?

In other words, are the "lulz" illegal here? Is it illegal to not be "serious" with the market (whatever that means)?

Let's suppose there's a massive oil spill tomorrow. Everyone goes on reddit and says, "Hey, let's destroy this company by executing the following actions with the following securities . . ." (let's assume this is possible for a moment). Is that "market manipulation?" Is that illegal? Is that "abusive" (as the SEC puts it)? After all, in that case, they are trying to abuse the company for reasons they regard as entirely rational and reasonable, and they're doing it for all to see.

Banding could also have been eliminated long ago by calculating gradients in higher bit depths and then dithering to 8bit. Sadly few graphics engines do this.

I think this represents an upgrade from being chased by tigers. Sedentaryism, metabolic syndrome, being fired by the machine, sweatshops, homelessness, addiction, those are downsides from foraging aboriginal lifestyle. But being terrified of losing money is different than being terrified of getting literally eaten.

Anecdotally, i appreciate the efforts towards their moderation and hope to see more in the future. It makes me more likely to use their products. I'm voting "with my attention" (to paraphrase a oft-used quote)
EU pre-ordered more Pfizer than the US.

Enough for 150 million people in EU, vs enough for 50 million in the US. The US has ordered more after it was approved.
Ikea used to sell two different versions of the Ladda battery.

The brown versions with lower capacity / higher cycle life did switch from Japan to China, but they've discontinued those(or at least no longer stock them @ my local store) for some years now.

The white Eneloop Pro comparable ones were and still are made in Japan.
Shitty name for an informative site.
Hmm. Is there an index of market makers?
> Can you elaborate on this? This reads as essentially false to my understanding.

No, it's not false AFAIK :)

By 'endpoint' I mean what an address on those networks actually *addresses*.

Both a Tor-address (a .onion hostname, or a regular web address if you use Tor to access one), and an I2P-address, are essentially similar to an IP-address in terms of being the address of a *machine*.

They are anonymized, but the data is routed to the very specific machine which the address is of.

A Freenet address on the other hand is the address of a *file* - basically a hash.

So in Tor and I2P, even though the machine behind the address is anonymous, you can still DoS it because you have the address of the specific machine where the data is at.

In Freenet, you cannot DoS the machine because the address does *not* tell the network where the file is stored. It only tells what file you get. Any machine on the network can serve the file to you!

And in fact, if you try to DoS a file by requesting it very frequently on Freenet, it will instead be distributed MORE on the network: Machines along the path where the data is routed will cache the file.

That's what provides the censorship resistance.

It’s because most ‘subwoofers’ are glorified fart boxes that have terrible harmonics, coupled with the fact that placing a subwoofer in the wrong spot can create poor room frequency response. Two subwoofers is preferred. Four subwoofers is the sweet spot. Any more and you get diminishing returns. Full-range speakers can work for a lot of music because most music has hardly any information below 40 Hz, the point where many ‘full-range’ speakers become inaudible.

For content with significant sub–80 Hz content (i.e. movies, organ music, and Drum & Bass), subwoofers are more economical and arguably better for several reasons. One, bookshelfs+1 or 2 subwoofers is cheaper than all five full-range. Two, the subwoofers will offload power from the amp. Low frequencies have a tremendous amount of power in typical sounds. Three, the subwoofers can be placed anywhere so long as the cutoff frequency is set to 80 Hz or less. Above 80 Hz, the consensus is that the sound becomes locatable. The arbitrary placement of subwoofers is important because it allows you to place the subwoofer in a place which will excite room modes or attenuate room modes such that a more desirable room response is achieved. These positions are usually not where you would want to place speakers.
This is just a childish rant. To lump everyone into the basket of only using coworking for "a sense of community" is entirely a false premise.

Also, the cussing is disgustingly unprofessional. Not funny. Not cool.
It is! We look at both the number of times a stock is mentioned in total, and also the number of comments that it's mentioned in. We do get some false positives but for the most part it seems like genuine chatter. We're looking into creating a blacklist for bad actors.

Chinese and the Russian vaccines were not even considered. Now those are used in mass vaccinations, soon EU would be behind all countries but those who barely have any government at all.

People don't even want to talk about that, as if those alternatives don't exists. Non-EU countries in Europe are getting them. Serbia(6.1) and Turkey(2.3) are already close to EU average(2.6) or better on the vaccination process.

Well, the other fat cats will have a claim on a fair share in the assets of the bankrupted; the WSB investors would not have any claim whatsoever on the assets of a bankrupt hedge fund who shorted the same stock - they will have the stocks they bought, the fund does not owe them anything, the broken promise to buy and return loaned shares was to some broker, not to any retail investors.

If we had a popular vote then UKIP would've had nearly 70 seats back in 2015, with a huge swath of representation for London. Somehow that sounds even worse than what we have now.
I’d love to see a content platform where you can only get downvoted if your content contains logical fallacies, or if your tone is hostile or disrespectful. Basically combining the civility of HN, the breadth of content of Medium, and the crowdsourced moderation and badges/point system/gamification of Stack Overflow. Something like the following:

-You can post any content you want.

-It must be civil in tone.

-Other users can tag your logical fallacies.

-If their tags are accurate, your article is downvoted.

-Downvotes only happen if your article contains logical fallacies or violate the civil discussion standards. You can’t downvote someone without tagging a logical fallacy.

-You explicitly cannot downvote or tag someone’s content simply because you disagree with it. You can try of course, but if your tags are found to be consistently inaccurate, you get shadow-banned or something.
Without dithering 8bpc is not sufficient to avoid banding, especially on very shallow gradients or those covering large areas. The color steps may be subtle but the step-like way in which bands change is still visually distinguishable.
Are you surprised at this?

You are familiar with entropy, right?
Hey, it is a good idea and nice website. This immediately reminded me of the recent attempts with GPT-3. When I clicked on the website link, I expected a small demo, a space where I could type some simple commands and see it in action. Personally, I would not pay for it/pre-order before seeing some hands-on functionality at least. I admire your efforts of creating the 'semantic engine' and I can imagine how much time went into that. I hope you can get a working version as planned, and I'd be interested to try it out.
I think it's a big fat "it depends". For example, do GIFs even do HDR? And is there a 10-bits-per-channel specification for PNG's? (I haven't tried to look that up.)

Since HDR is a superset of the non-HDR color space, I suspect there will be not that much fuss converting 8-bit to 10-bit, but a whole lot of "magic" involved in converting 10-bit down to 8-bit.
Awesome, does that mean OSU can ditch prison orange as its school color now?

What an excellent post.
This is definitely one of those things that may all be somewhere within the bounds of the rules, and the SEC will allow it, as long as you don't fuck it up. A "don't ask don't tell" kind of situation when firms tread into the grey area between the black and white of strict rules. My boss always used to say "We don't have many rules, just don't be the reason why we have to create a rule".

4.5) Because of their insane overuse of margin to ease onboarding, their depository obligations begin bleeding beyond their ability to triage, putting the accounts of both their investors and clients at risk.

5) RH then "margin calls" all of the people who had money transfers pending at the time of GME purchase (in order to reduce the overall risk profile of the robinhood brokerage and to scrape back as much money as possible to cover their depository obligations which they, goto 1, screwed up themselves by offering way too much margin to clients who didn't know they were getting margin (or what it even is))

Over the past two days, Robinhood royally fucked it up, beyond anyone's wildest fears. If they were Chase or BofA or someone, I'd say they're systemic and will get by to survive another day. They're not.

Robinhood is finished. If they somehow manage to meet their depository and net capital obligations over the next few trading days, and if they somehow manage to survive the large downturn in users the platform will experience after their actions this week, and if they survive the inevitable congressional hearing, they'll still have the SEC investigation to look forward to.
Sources? Because everything I've read is that each got a 100 million dose initial order, so that's 100 million people total to begin with. Moderna was already part of Operation Warp Speed, the contract signed 11 August 2020 according to Wikipedia. Pfizer refused to be a part of it, but in July 2020 signed a 100 million dose order contingent on getting regulatory approval. Both have since signed additional 100 million dose contracts, and Moderna an option for an additional 150 million.

Operation Warp Speed worked with Moderna, spent a lot of money on both them and various parts of the supply chain to do the best to manufacture this new type vaccine as fast as possible, and I've not heard anything about their failing in their promises. Whereas Pfizer initially went it alone, and starting in December has been failing to keep their promises everywhere, now even shutting down their plant in Belgium to increase capacity.
Workstations and desktops are distinct market segments. The machine in the article uses a workstation platform. And the workstation processors available in that Lenovo machine clock slower than something like a 5950X mainstream processor. The RDIMMS you need to get to 1TB in the machine run much slower than the UDIMMS I linked above.
I guess I don't understand what the fundamental disagreement is here. Most astronomers believe the probability that Oumuamua was an alien visitor is very small. Loeb's argument is that the probability may be a bit larger. But we'll (very likely) never actually know which it was, so the disagreement is about the unknown likelihood of a single observed event. It just seems obvious that we'll have to settle for "probably a funnily-shaped rock, but there's a small chance it was something more interesting" and live with that.
Yeah, no. This is similar to Republican claims of election fraud: it's entirely plausible (and downright indefensible to not believe) that voting machines are subject to manipulation, but at the same time there's just an astounding lack of evidence any such manipulation exists.

Just wanted to comment on the usability of directory listings (Apache server?). No javascript bs, no UI frameworks, no SPA garbage, just good ol folder listing in HTML. Glorious, fast and shall I say, impeccable?

In 2021, this would be a "card" based page, about 6 cards visible, rounded corners, and it would have fucking infinite scroll, ofcourse with spinners to let you know its processing. God, help us.

Edit: I should clarify, I like JS for form submission and a few things. If you're building Google Docs competitor, by all means, go for SPA and big JS frameworks. That's what they're designed for.
So there are 2 parts to cpu affinity. a)
cpu assigned to ssd for handling interrupts and b) cpu assigned to fio. numactl is your friend for experimenting with with changing fio affinity.

https://access.redhat.com/documentation/en-us/red_hat_enterp... tells you how to tweak irq handlers.

You usually want to change both. pinning each fio process + each interrupt handler to specific cpus will reach highest perf.

You can even use isolcpus param to linux kernel to reduce jitter from things you don't care about to minimize latency.(wont do much for bandwidth)
The paper covers the reasons, and they aren't new or specific to Intel.

As an close observer, I’ve lost a lot of respect watching how the EU in general has handled the whole covid and vaccine mess. They got a away with a lot of shit because USA/Trump/India was a bigger and more obvious bogeyman/disaster. Multiple times there were stories that were just factually untrue that were parroted by leaders in Europe about covid or the vaccine effort. The same bogeyman stories came out about masks being hijacked, Drugs being boarded by Indians or respirators being seized and the USA “buying” all the vaccines and drugs and leaving Europeans to die. Meanwhile the USA and European covid rates pulled equal and Europe now has the dubious honor of leading total cases by 4 million.

What is now true is that Europe has staked itself to a inadequate short term supply, and is now hell bent on limiting vaccine to the UK to make up for its distribution woes.

In the United States it’s looking like a half of project warp speed failed. The GSK vaccine is dead on arrival (2.1 billion) and novavax hasn’t even fully recruited their US study. 4 out of eight billion for vaccines unlikely to make a difference in the USA but the other 4 looks like enough to vaccinate the whole population by late summer.

Hopefully it looks like Europe is going to get Novavax. Despite the USA spending $2 billion prepping that vaccine, it probably won’t be available until early fall in the states at best - so the US company will instead supply Europe. Astra Zenca made mistakes on their studies, and we still don’t know what the over 65 response rate is. It’s being approved because people are hoping that it’s effective. It’s a crappy place to be. But between those two vaccines, there might be enough. The

The entire vaccine mass is a reflection of lack of cooperation between Europe and USA right now.
Not a CFA like DFV, and not financial advice but here goes.

A way to assess what any stock is valued is to take the DCF, but since it's nearly black box to the shareholder for growth companies (no dividend), treat any interest payments on outstanding short float as part of the DCF. That means there's a growth directly associated with capitalization. so it makes sense that the capitalization becomes untethered with the business. Google’s ROE is about 12%, so 6-7% on the cap isnt great, but it’s not nothing either. The other side is if the short interest decreases that would collapse the cap sharply, but the longer the shorts wait, the less lucrative and difficult it could get.

well really, at that point everyone's purchasing power is diminished, so the game remains zero sum relative to anything outside itself.
All of that risk is associated with holding the goods and currency for this delayed period! It all makes sense, but, if ACH was 10 minutes instead of two days, the entire issue would barely matter.
Correct. It's a tax treaty form and there is no visa application required if you are only working from Canada. Many companies don't know about it and think that paying people out of the US will be a big headache, but they literally only have to fill out the one form and then not take off tax. It basically says "we both are confirming that the Canadian works in a place with a tax treaty with the US and will be paying income tax there so no tax needs to be with-held". I worked somewhere that knew this first, and then worked at 2 more places where I had to educate the payroll department about it! (They tried to send me forms that clearly said "I am a US citizen" and I was like "hellooo I can't sign this, that would be fraud".
I think the much simpler "conspiracy" is that a few people in WSB have been using the platform to pump and dump stocks and this one just got a little out of control.

RH has fucked up a bunch here, but there are some folks who are going to make a killing on this (maybe already have). It's quite possible there are a few front-runners on WSB who are talking GME up like mad even as they quietly sell off shares for a big profit. The front runners have big profits on this deal.
Right, if you're using xmm regs you're getting double or single precision. Sometimes the x87 regs get used and that's when "accidentally computed with extra precision and then double-rounded" comes up.

You said

> Prior to 2020, most medical professionals believed most viruses, and corona viruses particularly, could not be transported as aerosols. This was a subject of research where the data had not come in.

cactus2093 replied

> I've also looked into it a little and come to the opposite conclusion. Here is one study from Singapore in 2014 that showed surgical and n95 have about a 68% and 95% efficacy respectively at preventing SARS transmission https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4293989/ Masks have also been shown to provide protection against the common cold (many strains of which are also coronaviruses) and seasonal flus https://www.livescience.com/7661-masks-protect-colds-flu.htm...

There's two ways I can see you interpreting this.

1) You are being extremely narrow in your focus and saying that you are talking specifically about viruses being transmitted as aerosols (although the overarching topic here is about whether or not masks are effective). And thus, since there was no research specifically about this, then there's no reason to recommend masks. This doesn't address the point that there's research that shows masks are effective against similar kinds of viruses.

2) You actually are talking about effectiveness of masks and saying that viruses could not be transmitted via aerosol was to say that because they are not shown to be transmitted via aerosol, then there's no evidence that masks would work, in which case, again, we're back to the issue that there was research prior to 2020 that showed masks are effective against similar kinds of viruses.

So the question remains, are you wrong about your assertion that

> Prior to 2020, most medical professionals believed most viruses, and corona viruses particularly, could not be transported as aerosols. This was a subject of research where the data had not come in.

and if not, what are we missing about what you're trying to say?

> Some kind of admission that the US health field ignored research because "eww, icky Asians?"

There was certainly the perception that Asians wearing masks was ridiculous. Whether or not this perception extended to American experts and influenced their conclusions is unknown to me.
I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a comment.
