I’m an ENT surgeon and I’ve personally used the service.

I asked about the safety of a drug and the product gave me a summary and literature to answer complex clinical questions fast. This product does a lot of the work that before involved me lots of time clicking and searching and trying tons of different Google searches. For a busy physician it works great.

It saved me time and helped ensure I was using the most up to date research for my decision making. This would’ve been a game changer when I was at an academic hospital doing clinical research, but even as a private physician it’s great to ensure you’re always up to date with the current evidence.
I guess it depends what you mean by "the market". A lot of money which previously would have been allocated to public equity credit or bond markets is now being allocated into private investment (PE, VC, private debt, etc etc). A key selling point for those investments is that they are "outside" the (public) markets.
Is this the white privilege thing I was hearing about?

Have you played the game? That is, maybe, the first hour of a game that lasts many many dozens even hundreds of hours. Mining only happens in the first five or ten minutes. There are a host of other interactions, from tweaking object settings, optimizing pathing layouts, planning, direction of bots, to deployment of the factorio equivalent of Redstone circuitry.

And mods. As with KSP or minecraft, a greater number of possible interactions comes from the modding community rather than the stock game.

> It’s not a far left paper, centrist at most. It’s not like they’re calling for workers to seize the means of production.

In this case, I'm sure pretty sure "far left" has nothing to do with policy, and actually translates to something like "not loyal Republican" or "not seeking to spare Republicans embarrassment."

It's sort of like how RINO has come to mean "disloyal to Donald Trump," and gets applies to people who'd score 100% conservative on any ideological test.
They're also a joke because they are, as far as I'm concerned, not a "brokerage". They are an app designed to convince people that they understand how to trade stocks, in order to sell them stocks.

A real brokerage should, in my opinion, and some sort of duty to act in the best interest of its clients.

A brokerage should not have huge backlash because its users got margin called, and those users didn't even know what a margin call was.

They should not have huge backlash because its users stop-loss orders were triggered, and then executed at a lower price.

This is just confusion that shouldn't exist, because a reasonable brokerage shouldn't be luring people into these risky positions just to make a buck on the sale.
I don't get this. I can't imagine the professional investor class is still blindly following their shorts. They're all out by now, aren't they? If the "little guys" are making money I tend to think it's coming from other little guys.

The "their" in your sentence can be read as ambiguous as to which parties its referring to, aptly.

With crud like rwsb posters asking if letting their deep in-the-money calls expire unassigned will screw the funds more-- it may well be the case that it isn't fund blood in the water that you see in this feeding frenzy, at least not anymore.
OCaml seems like it hits all of those well.
Ruby is fantastic for scripting. It has quite a few of the same conveniences that made Perl great for scripting and it's a lot easier (for me at least) to maintain and understand when seeing it months or years later.

The Psychology of Stock Bubbles
Just quoting FB's wording and my hunch. As the other commenter gave an example, if you have a niche product which only a fraction of people would be ever interested in, it would help if you can know who those are, and restrict targeting to them.

I can search for knitting needles or be viewing a knitting post on Instagram. If an artisan needle seller wants to target his product it doesn't help targeting people who are not interested into artisan stuff. So to maximize the ad budget impact the ads are better left targeted specifically to people who have a higher likelihood of buying artisan stuff. This problem doesn't affect some mass market knitting needle seller.
> This is all quite strange considering how much of a game changer and scientific motivator evidence of ETI would be.

All conspiracy theories aside, there is an argument to be made that something with the potential to completely undo the status quo would, in a less-than-ideal world, have a hard time finding funding from those at the top of the totem pole of power.

> I spend most of my time on a large C++ project that does neither of these things, and I still use gdb a lot.

I think that, when GP wrote "windows", they meant the operating system. And when they wrote "debuggers work well", they meant the quality of debuggers, not whether using a debugger is a good idea. Quality of Windows debuggers is generally on a whole other level than on Linux. Chromium DevTools also has a nice debugger. I don't know about Java.

I'd argue that those things aren't fundamentally different than anything going on via WSB (assuming no bot accounts saying buy buy buy or something similar).

I think the difference is that for these other items there's nobody around to measure the impact.

How exactly would they do it? Shorting it again would involve calling the top for a stock whose price recently has been unpredictable, but very high.

Writing options seems nuts for something this volatile. I guess they could "buy volatility" with a straddle but again what would the numbers have to be on this where they turn a profit? It's not like the rest of the market is underestimating the volatility, it's evident to everyone.
Author here.

We started working on Pyroscope a few months ago. I did a lot of profiling at my last job and I always thought that profiling tools provide a ton of value in terms of reducing latency and cutting cloud costs, but are very hard to use. With most of them you have to profile your programs locally on your machine. If you can profile in production, you often have to very lucky to catch the issues happening live, you can't just go back in time with these tools.

So I thought, why not just run some profiler 24/7 in production environment?

I talked about this to a friend of mine and we started working. One of the big concerns we heard from people early on was that profilers typically slow down your code, sometimes to the point that it's not suitable for production use at all. We solved this issue by using sampling profilers — those work by looking at the stacktrace X number of times per second instead of hooking into method calls and that makes profiling much less taxing on the CPU.

The next big issue that came up was storage — if you simply get a bunch of profiles, gzip them and then store them on disk they will consume a lot of space very quickly, so much that it will become impractical and too expensive to do so. We spent a lot of energy trying to come up with a way of storing the data that would be efficient and fast to query. In the end we came up with a system that uses segment trees [1] for fast reads (basically each read becomes log(n)), and tries [2] for storing the symbols (same trick that's used to encode symbols in Mach-O file format for example).

After we did all of this we ran some back of the envelope calculations and the results were really good — with this approach you can profile thousands of apps with 100Hz frequency and 10 second granularity for 1 year and it will only cost you about 1% of your existing cloud costs (CPU + RAM + Disk). E.g if you currently run 100 c5.large machines we estimate that you'll need just one more c5.large to store all that profiling data.

Currently we have support for Go, Ruby and Python and the setup is usually just a few lines of code. We plan to release eBPF, Node and Java integrations soon as well.

We look forward to receiving your feedback on our work so far. Even better, we would love to hear about the ways people currently use profilers and how we can make the whole experience less frustrating and ultimately help everyone make their code faster and cut their cloud costs.

hedge funds put in some money. They lost. Yeah. But automated trading solutions quickly flip things around. If they are smart. Losing money is literally part of what they do. Some they lose some they win. The success is winning a bit more than you lose, and very frequently.

Yes, it's a reductionist argument that can apply to literally anything. Let's just delete all user discussions on the internet, and only allow PhD granted experts to discuss things on panels where they must provide primary sources for everything.

Or you could simply point out when someone is wrong, and explain why, assuming you are an expert. Then we all learn.
I cannot stress this strongly enough -- the fact that buying was limited yesterday is not evidence that the little guy is actually winning.

As has been explained in multiple other places, the limitations were as a result of Robinhood et. al. being unable to cover the risks involved in providing instant trading capabilities for a stock as volatile as the ones that got restricted. That has nothing to do with "the little guy is winning" whatsoever, and in fact may indicate that "the little guy" is about to lose his shirt, due to lack of predictability.

Trading was not stopped "to save the hedge funds". This is an outright lie that needs to be squashed. Stop saying this. I don't mean to be rude, but the narrative you're spreading is actively dangerous and not supported by any of the facts we have available to us.

I know there wasn't much in my comment but really what I'm thinking of is akin to a steering wheel in a car. Where you move a lever and it effects the system in a novel way. Where most of what we have is variations on text entry and boolean flipping. If we step away from web applications you do have a whole plethora of UX innovation inside video games, apps, and products in general. I am enamored with the elegance of simple portable battery packs for example.

Re: Subtleties.

I disagree. I think a big part of why this whole thing is fascinating is the depth. Yesterday morning, financial press were blathering generalities pinning WSB as market manipulators and calling for regulation to stop them. That is, stop retail investors trading at a scale that moves markets. IE, the stuff that insiders get away with regularly.

Between yesterday afternoon and now, millions of people have been catching up on the detailed mechanics of stock trade execution. There's a mad dash from reporter to get interviews with brokers, clearing house operators & such.

Note that the maneuver itself was analyzed in detail, and in public. That's what allowed big names like Cuban, Musk, various politicians and such to take a side and comment on it intelligibly.

Ultimately, whoever is holding these meme stock shorts needs to buys stock to cover their positions. I acknowledge that brokers had legitimate/legal/normative reasons to stop retail buys. But, it's also true that they created a window where short sellers could buy without competition from retail investors. Maybe brokers are covered legally against market manipulation charges because clearing houses were genuinely short on liquidity. But, (1) that doesn't change what happened and (2) Isn't this the regulator's job?

The reason people are cheerleading is because of these shenanigans. "Rigged" gets thrown around often, usually it's devoid of subtlety. This time, it's detailed. We can debate the details and construction of the rig. Truths fly around reddit for an afternoon, and are discarded the following day.

Few people cheerleading because they want a no regulation, pre-depression stock market. They just aren't willing to accept a rigged system. In any case, who are the speculators here? Short sellers like Melvin or Redditors? Short sellers future-sold 140% of the stock... hoping for a crash and potentially creating one. Redditors recognized this by looking at publicly available information and discussing it in the open.
I wonder which one is easier to implement. A future utopia where every thing is great for everyone or an ad-less society.
> This feels to me like Apple creating a convenient Orwellian enemy.

Apple isn't "creating" an enemy here. They aren't running full page advertising against Facebook. Apple is making it so users have to give permission before companies can utilize an API. Just giving that one power to end users has apparently scared the hell out of Facebook.

> ...why would Apple allow Facebook in their App Store and take 30% of the generated revenue?

Apple doesn't get 30% of Facebook's generated revenue. It gets 30% of sales and in-app purchases. Facebook doesn't use either as far as I know.

> If anything, the App Store made Facebook more popular than ever, so it's a "monster" that Apple helped create.

If they had perfect foreknowledge, Apple would likely have done this from the start. Steve Jobs made it very clear at the time that Apple itself should ask permission before collecting information every time. If they'd foreseen influential companies like Facebook creating APIs which were widely spread through the App Store, they'd have likely closed this door a long time ago.
It's a good pdf by Apple. And clearly aimed at Joe Public. Getting Joe Public to understand some of the damage being done via data mining is not easy. Policing abuse of that knowledge through unenforced laws, business ethics, or guidelines, has failed. Now Governments internationally are going to impose new laws on the giants. It'll level the playing field for those with already with ethical practices, but for sure, greater restrictions will be bound in to the new laws that spoil things for everyone, and it'll be within 12-24 months.
I mean, some hedge funds are making money, sure. But the point is that, collectively, billions of wealth have so far been transferred from institutional investors to regular investors.
Congrats, you hit the Smarty's Catch 22--thinking you found the error in the smart people's oversimplified reasoning with oversimplified reasoning and then throwing stones.

I’m not sure that’s true. All of Apple announcements seem to more broadly target the large data brokers you’ve never heard of.

Facebook seems to be making themselves look like the target for browny points, that plus their recent data fuckups means they’re probably the first name that pops into people heads when you say “abuse of peoples data”. But that’s just an inditement of Facebooks dodgy data practices, not evidence that Apple implying or targeting them.

Quite frankly I don’t think Apple gives a shit about Facebook. Why the hell would they? There’s no profit in targeting them specifically.
They get hit indirectly, not because the small businesses sell ads - but because they buy targeted ads on Facebook (and those targeted ads work).

Edit: Smaller companies also rely on these IDs because they aren't able to track in other ways in the way that the large companies can.

That said, I still think this ad-driven model is bad and if it became non-viable I'd hope long term privacy restrictions would also make it non-viable for the large players too.
I am so sick of this 'stay in your lane' attitude. Time and time again, experts have been shown to have consensus opinions which are wildly off from reality. You can almost set your watch to how often an outsider will analyse a situation from first principles and make money off the 'experts', especially in the stock market.

You're welcome to your opinion but this appeal to authority is seriously wearing thin. Pretty much the only field which hasn't been embarrassed by an outsider of late is physics, and even that might not last forever (I remember the smugness with which Stephen Wolfram is routinely dismissed from having non-consensus views of physics).

Progress almost always comes from non-consensus outsiders. This whole website is supposed to be a testament to that!

There's no need for SEC to redefine market manipulation - IMHO the "pumping" activity of at least some WSB activists would perfectly match the existing legal definition of market manipulation as written to prevent historical "boiler room" type activities.

On the other hand, in these discussions I have seen a bunch of assertions that what the shorting hedge funds or HFTs are doing is "market manipulation" - now that is an attempt to redefine market manipulation to something entirely different than what it is/was.
> I don’t know how you can argue this in good faith

I'm not an expert and am rather dumb.

What do you think the differences are?

Differences:

* One hedge fund versus a multitude of investors

* Owning all the securities vs only a portion

The similarities are:

* Intentionally buying all the stock to cause a short squeeze

* Explicitly recalling borrowed shares to cause a short squeeze

To be clear, I'm not arguing that what wallstreetbets is doing is illegal but something fairly similar is. I thought an actual example of market manipulation was relevant to the conversation.
I saw plenty of smart people ahead of institutions and real doctors on masks and to some extents other aspects of the pandemic.

Yes, in general if you don't know much on a topic you'd on average do best if you listen to the experts but you can outperform that if you can identify the right kind of smart people with a good track record.
So I've been wondering about how this is different.

I'm wondering, at what level, this can become a self-fulfilling prophecy?

A lot of the talk has been that the stock price doesn't reflect the company's 'true value' (it's volatile and mostly inflated). But there are a few outcomes that truly increase the company's value. Obviously the brand/marketing aspect -- lots of free marketing. New key board placements show that they are potentially restructuring/refocusing and that potential strength is highlighted by the public messaging within WSB. (The messaging is obviously disproportionate and a reaction to negative valuations by the those that shorted it...but still influential.). It seems to be growing at about 1m+ per day. You have a lot of influencable eyes on content there.

What if GameStop gets essentially treated like a defacto co-op of sorts? What if WSB helps coordinated buys? What if it becomes the "preferred retailer" for purchasing/selling consoles? (Even going so far as recommending against purchasing from other retailers). What if it gets championed as some sort of anti-corporation corporation. What if WSB helps guide whatever transition is necessary at the retailer (e-sports? some sort of wework-gaming hybrid? Sustainable? who knows). The brick-and-mortar retail space is going to be very unpredictable in a post-pandemic world.... There could be a certain pride and self-interest in helping drive gamestop's business. A lot of the wit and intelligence gets overshadowed by outside reading of the memes. The mods over there are very smart and there's potential for something well-organized to come out of this.

We might look at how WSB affects Robinhood as a business as some kind of indicator of the massive power of such an organized group.

The company has the potential to become as valuable as the "inflated" valuation.
