Be careful not to fall into the narrative the mainstream US media is selling, though it shifted drastically yesterday -- this is not a coordinated attack. WSB is full of people shilling all types of tickers for all types of reasons, but there is a large amount of people there who understand (or at least pretend to) the dynamics of a gamma + short squeeze, and are in it for that reason.

The person who posted one of the earliest bull case research for this (referred to by his YT channel name RoaringKitty or his reddit username u/deepfuckingvalue) has been into GME since last year. He was holding LEAPs (long-dated call options) and shares and has been holding for the last year. He was ridiculed in the original post, because everyone still believed Gamestop was Blockbuster v2. Gamestop is not Blockbuster v2 (I used to think it was), but what's happening right now is not about fundamentals (and if you see anyone arguing that, they are trying to trick you by reframing), it is about the mechanics of a combination of a gamma and short squeeze happening at the same time.

Hedge funds do this kind of attack when they realize the opportunity is there -- you don't hear about it because it doesn't make the news, and because the news makes up a rationalization. Here's an example -- a bunch of stocks that were essentially left for dead (heavily shorted) popped yesterday and the rationalization was retail jumping in. That makes sense, unless you take a second and think about it -- how can the retail that's all still all-in on GME be simultaneously moving huge amounts of market cap of smaller companies? Yes those companies were cheap but they're cheap because they were shorted -- this means anyone could move them. Don't forget that ~90% of all stocks are owned by the top 30% or something like that. Retail can possibly cause gamma squeezes (see TSLA last year), but institutions have to take part for it to go anywhere.

It is 140% the fault of the short sellers that didn't take profit last year (assuming some rode GME from 45 to 5, this is a ~10x position If i understand correctly) that this short squeeze had the chance to happen. Greed got them.
First of all, I don't get my news from those places. It has taken over a decade, but after flipping the bozo bit on dozens of news media firms, I feel I am a bit closer to having some idea of what's going on. If all you have is e.g. NBC News, then assuming that all the "wishful thinking" (which at times is over half of the content: "this time we've found a war we can win!") is exactly wrong will get you pretty close.

Second, you don't have to read the news to know that people are dying. In vulnerable populations, the increase is impossible to hide, especially since no one has gotten the flu this year. Old physicians and researchers who aren't trying to build their personal brands all agree (and have agreed since February last year) that masks and isolation are the ways to cope with respiratory pandemics. I'm hopeful for the vaccines, but I fear they won't deal well with the mutations that have never been conclusively ruled out. At the very least, vaccines are unlikely to harm people who don't have some sort of weird precondition. Besides which, unlike 99% of USA healthcare, they're free.
They sent an email yesterday:

"As a brokerage firm, we have many financial requirements, including SEC net capital obligations and clearinghouse deposits. Some of these requirements fluctuate based on volatility in the markets and can be substantial in the current environment. These requirements exist to protect investors and the markets and we take our responsibilities to comply with them seriously, including through the measures we have taken today."
Well said. A redefinition in design not driven by big tech would be a great initiative. Maybe even an open source data bank of non dark patterned practices.

Silicon Valley is no longer about startups, in the sense of scrappy challengers to established industries. It is now about maintaining the establishment of the top ~10 tech firms.

What can you do? Build a company in your own country and fund an independent ecosystem that doesn’t rely on Big Tech’s money or ex-employees.
What makes you think there is a “good side” of Silicon Valley? Genuinely curious how such naïveté can still exist in the wild.

Google has gone rogue for a long time. But for UX, it's not necessarily dark pattern. IMO, there is a bad smell, started by Google, particularly Chrome if I remembered correctly, which tends to hide menus/actions by moving them under the burger/3 dots menu. Such behavior saves a little bit screen estates but adds one extra click to finish one particular operation and the bigger problem is that it hides the available options from the user and in turn makes applications less intuitive.
Yea, so? How is this the same thing? He paid for that service. It's equivalent to paid support tiers where your query gets answered faster than others. Or is it just fashion now to shit on rich people even when they are playing by the rules?

How do people take this guy seriously?

All that froth allowed finance companies to suck out hundreds of billions in fees, encouraged lunatic risk-taking in every direction and rampages of private equity takeovers, and kept a vast stable of functionally dead companies alive on cheap credit. Those so-called “zombie companies” make up roughly 30% of all corporations in America now, and they racked up over a trillion dollars in new debt since the pandemic alone.

His own link(!) points out that these "zombie companies" include the WSB long target AMC (fair enough), Tesla, and, wait for it, Moderna. Did he even read it? Or does he assume we won't?
It can be argued that they don't have liquidity issues - they have collateral deposit issues (Due to the massive user growth, and the delay between when an ACH transfer to Robin Hood clears the banking system (a few days), and the time they permit you to trade on your account (less than a few days))

It’s not a scam it’s just a pretty mediocre broker with a fancy ui. Lest we forget they introduced many traders to options, for better and worse. They are/were WSBs broker of choice. They changed the fee landscape in trading US-wide.

It’s hard to say they weren’t impactful, though we can disagree on the positivity of the impact itself.

So currently some hedge Fonds are bleeding money, true? So who is the counter party who currently gets this money (can't be the community since they hold)
Revenge against the finance nerds. If the finance nerds bought companies made by tech nerds they’d be fine.
An exotic instrument is basically any contract more complicated than a simple put or call option.

For a slightly fictionalized version of why these might be useful in the real world, let's say a Finnish life insurer is selling life insurance in Hungary. So, they're doing their accounting (the numerare) in Markka (FIM), taking in payments in Forints (HUF), and exposed to changes in Hungarian mortality rates. So, for the next 30 years, this insurance company wants some secondary protection against adverse shifts in the Hungarian mortality curve, but to make that insurance less expensive, they only want protection if those losses in HUF, converted to FIM exceed 100 million FIM.

So, this insurance company goes to the structured products desk of large multi-national firm and gets a very bespoke option created. The multi-national sells this single contract to the insurance company, and hedges the individual FX components using FX options and the actuarial risk with actuarial derivatives. There's basically no market for this stuff, so the large multi-national basically commits to hedging out the other side of this contract for the next 30 years.

I've worked with optimizing risk modeling for exotics, because it turns out that for some of the more complex exotics, the daily computational costs get very expensive for basically re-calculating a first-order multidimensional Taylor approximation (the risk components) of these contracts. Every day, we then take these risk calculations and buy/sell a bunch of simple options to bring the first-order partial derivatives (risk components) back close to zero.

Reflections on Implementing a Basic NES Emu (2019)
There's another somewhat related problem: UI fatigue.

Many companies have now gotten into the habit of changing their UI with every release, moving things around and changing the depth at which functions lie. Apple is particularly guilty of this. Try following a tutorial for adding a button to a view in Xcode - the UI to open the assistant panel isn't where their documentation says it should be.

And this happens with every single release of Xcode. There isn't a single Xcode tutorial on the web that is accurate anymore (not even Apple's own docs).
I think a general case is concurrent mutation of a data structure. If you are adding some item to a list in parallel with others, you will usually need to return some token (e.g. index) that will allow your caller to retrieve that item later.

You MAY be able to get away with making this a pure function by returning a shallow copy, but I believe that depends on how central the sharing aspect is.
It's a young field. We need UX/ advocates with a seat at the table defending the users. Better yet, we need UX advocates across the board.

But it'll take time, most companies are just getting into it. But making better UX a company wide effort is a good start.

As for the bigCorps, obviously this is a wider discussion than UX alone, as having these dark patterns fall through the process indicates a certain problem in company culture and/or decisionmaking.

It's a bit early to start losing faith, we're just getting started.

There are multiple layers of protection against HTTPS-to-HTTP downgrade attacks.

① An HSTS policy will protect people that have visited your site within max-age seconds, typically “within the last year”.

② An HSTS policy with preload will protect everyone.

③ HTTPS-only cookies will prevent them being sent over plain HTTP.

⑤ You could depend on various newer functionality that is only available in secure contexts <https://developer.mozilla.org/en-US/docs/Web/Security/Secure...>. For example, the Web Authentication API. (This also raises a good point about using the Web Authentication API for security: authentication is tied to the origin, so http://example.com, https://example.com and https://example.com.evil.example are all different origins and no one will be able to log in over the wrong origin.)

⑥ Any JavaScript code can check the origin and rebel if it’s not what you expect—in fact, I’d say that it’s very common to do this quite incidentally. This protects against a drive-by downgrade attack, increasing the effort required by the attacker who must now reverse-engineer a bit of your code.
Exactly. If a simple website is overloaded with JS it's because you're the product not the user.

People who are clutching their pearls about this are only trying to protect rich friends who are hedge fund managers.

Lots of hedge reptiles were on the momentum side rather than the short side. They've ridden it up, and eventually they'll ride it back down. There's no way they'll allow regulation to interfere with this sort of opportunity. Smart money does not outlaw dumb money.
if a single stock can damage the entire system - perhaps it is the system that's not well designed?

> People think this is somehow “taking money from hedge funds”.

The hedge funds used to have money that plausibly soon they won't. It is taking money from hedge funds.

> do you think that the retail traders who yolo’d their savings (there are many of these) will be the ones to sell at the correct second?

Or any point before that second but after the price has increased above what they paid? Quite a number of them I would expect.

Also, it's possible to use limit orders, so that if a short squeeze happens and causes the price to go up above the limit, the person's shares are automatically sold.

Or it could all go wrong in several different ways. It isn't a low risk activity. But if the risks are out in the open, where's the scam?
His supporters seem to be continuing to use Twitter.
> What triggered Alphabet to suddenly get involved? I'm assuming that these reviews didn't appear recently, suddenly or something.

They did appear recently. The latest pre-today copy of the page at archive.org [1] had it at 166469 reviews (average a tad over 4 stars). That was from 2020-11-17.

The next copy there was at 14:06 today (2021-01-28) [2]. It's up to 196808 reviews (average 2.5 stars). They captured it several mores times today. Here's a table.

14:06 196808
17:17 295104
18:24 306315
19:17 327577
20:22 330648
21:02 319501
21:36 246084
22:25 202305

and they have two captures from tomorrow:

00:24 180490
02:23 178221

If we play it safe and assume that all the reviews as of 14:06 today were old reviews, there was a minimum of 133840 reviews today, which would have been 40% of the total reviews. More realistically, if we go with about 170k old reviews, it's more like 160k reviews today representing almost 50% of all reviews.

I remember enjoying Taibbi's "gonzo journalism" style fifteen-ish years ago in Rolling Stone. But whenever I've followed a link to his Substack newsletter, it seems to be, ah, a lot heavier on the gonzo part than the journalism part -- down the rabbit hole of cranky contrarianism with nary an editor around to reel him back occasionally.
> owning land is not productive

On the contrary, it's providing the valuable service of holding property that I don't want to hold. I'd rather put my capital to some other use. You seem to dislike arguments of "pure ideology" but the assertion that real estate ownership doesn't deserve return on capital seems like it's singling out just one form of capital. Or do you dislike profits drawn from other kinds of property as well?

You say it's settled economics, but you've misstated. Monopolistic excess returns are "rents." Competitive market returns are to be encouraged.

One interesting thing that happened today as I was selling my AMC stock/options is that they executed lightning quick. Normally Robinhood (especially this morning) takes time to sell these options, yet they were immediately picked up.

Would be crazy to think short sellers were buying up all the sell side stocks/options while retail were panic selling, to hedge against their shorts.

My Dad, still programming at 72, was one of the first people I know of to work as a remote developer. From about 1982 We lived on a remote-ish farm in Australia and out in the shed we had an IBM mainframe with a bunch of terminals and PCs on makeshift tables made from doors resting on filing cabinets. A couple of times a year some of his colleagues from the UK would fly out from the UK with a bag of tapes of source code, they would spend the next month merging their code and planning the next few months work.
Nope. The presence of the burger icon still affords discoverability even if a little less convenient. I can still see it and go "oh here is an icon and let me see what comes up if I tap it". In the GPay case, you see nothing and so assume there is nothing beyond what you're seeing. The thing is, a menu that you can tap to get at the QR code used to be there to help get to it. It was removed.

The news did not cover the nature of the limitations, they just said limitations. I called TD early in the day and the limitations were not about buying stock but rather about selling ("shorting" options), and buying/selling spreads (a combination of options with interesting characeristics).

There are two classes of broker here -- brokers that are backed by Citadel, and Brokers that have a different market maker/clearing house and/or are not exposed to Citadel. The WeBull CEO did an interview mid-day and noted that certain market makers and institutions (i.e. citadel and/or Robinhood) were calling banks for bridge loans in the middle of the day. He also mentioned that Melvin Capital was bankrupt. I think Citron got out (that's a different story) a couple days ago or so.
