The point of the break period is to give yourself time away from your work so by nature I'm not sure how 'productive' you want it to be because any other productive activity requires focus. If you want to avoid moving pictures during your break, the optimization of the time doesn't have to be productive:

- go for a walk (even if its only within your work area)

- talk if you're around someone who also needs a break)

- organize your time/ideas for your next task

- water your plants (if you have any)

- play with your dog/cat (if you have any)

- stretching or some other short spurt of physical activity

- work on a puzzle

- chess

- drawing

- meditate

- nap

Robinhood blocked its users from buying or opening new positions in GME. But allowed selling. From the outside, it appears to be a coordinated effort to drive the price down to protect the overgeneralized billionaire hedge owners. The CEO of Robinhood did interviews to 'explain' why they did it, but it was really just a word salad of an explanation.

CORRECTION: "60% of its users owned GME at the time." appears to have been incorrectly reported and since corrected.

To ensure that developers continue to develop for their platforms and users continue to turn to their platforms for implicit advice about apps, the same reason they do most things in their stores.

Apps with large install bases are implicitly valuable to the platform as they are popular with phone-buying customers. It's not in the platform's interest to alienate the developers of such apps as those apps, together, cause people to buy that platform's devices to run them. The incentives are aligned.

What you and many Robinhood users probably are missing is that your trade actually does take days. Actually go read the Robinhood settlement period info.

https://robinhood.com/us/en/support/articles/withdraw-money-....

This is not explained clearly, but it is essentially 3 days to settle (T+2). So if you sell a position you don't have the cash to buy for three days. If you have traded on Robinhood you have probably noticed that you "immediately" have the buying power from the shares you sold. That's not your cash, because it hasn't settled. For three days that's margin and therefore you could get a margin call.

The instant deposit is limited to $1000 (margin). But there were people saying they were forced to sell out of much larger dollar holdings. Those were probably people that sold out of one stock holding and then immediately bought into GameStop, AMC, etc... So they likely believed they were buying with cash, but they were in reality buying on margin.

Just to be clear, I don't think this is a good thing at all. A brokerage should not be invisibly providing you with margin, it should be very clear to users that this is happening.
Would require to set up a central registry or so, yeah. (Or finally a use case for blockchain!!!1!!! :-)

Not sure it would be worth it, I think historically excessive shorting has rarely been a problem, except for a few colourful episodes like these.
In 1929 a series of events took place, and some of it took a while to happen (like Ford shutting down for a few months) that pretty much (not completely) eliminated retail accounts from both the stock market and actually from banking. Much of the public swore off checking and savings accounts, never mind owning stocks.

It seems like the big money is changing its clothes to pose as children in order to get priority on the life boats ("Women and children first!").

The social circle of firms closely connected to this ruin of Robinhood and which had been short GME are the speculators. Short for longer than intraday == speculative. Short as a market maker for an hour or two is good for efficient clearing.

It's on the guys with the big money to gather their fortitude and ride this out in the most-trust-inducing ways they can. I think the big money is naive if they think it could be otherwise.

One more thing, I am reminded that a lot of the time, a retail investor will buy something, a weak stock, and ride it down to zero out of misguided optimism. Conducting margin calls on zero notice is going to be toxic to such people and I don't think the finance world really wants that money to leave the market for good.

Radicals aim for the root of the problem.

In these times it’s revealing that there seems to be a severe lack of solidarity and trust. In a crisis it is paramount that everyone does their best and that the strong carry the weak. That’s a very fundamental property of a community. But instead the inequality rises and many fear for their livelihoods. This erodes trust and can turn fear into anger.

At some point in the future there will be the last straw. It might be the financial crisis, the environment, war or everything at the same time. The kinds of problems cannot be explained away; excuses and lies won’t help. Only a sharp turn towards solidarity and sustainability can avert it.
Microelectronics cutting edge has been moving to smaller processes for the past 70 years. This is nothing new. If anything, the progress has slowed down.

Some fabs get closed down/rebuilt for a different process, some stay and produce parts that don't benefit from higher densities. Last I checked some ICs still get produced in 0.35 um processes. You don't need billions of transistors for an opamp.
It seems like their criteria for naming schools should simply be “PS-1” to avoid all controversy.

If we are to judge historical figures only by their failings, then even Martin Luther King, Jr. would fail to live up to the impossible standards being used.

Gandhi would also fall short, depending on one’s perspective.

Insanity. The irony is that the attempt to be “inclusive” is actually exclusive to some. For example, George Washington is a hero to many Americans, as is Paul Revere. Stripping their names, to be, makes me feel less included. While naming a school after Barack Obama seems to be on trend, but historically just as fraught with moral minefields as any other former president.
They aren’t essential, but they are actually useful. There have been some experiments with banning shorts, but they lead to larger spreads on longs because market participants have to hedge by going risk-off on longs instead of shorting affirmatively. Shorts can create moments of volatility, but they improve overall trading liquidity and reduce frictional cost of capital.

In it she demonstrates breathtaking ignorance of over 200 years of US law.

• 9/11 was in inside job.

• The Parkland, Sandy Hook, and Las Vegas shootings were staged.

• "Zionist supremacists" are secretly masterminding Muslim immigration to Europe in a scheme to outbreed white people.

The inverse correlation between parasitic infections and autoimmune disease is interesting and is explored in Parasitic worms and inflammatory diseases, P. Zaccone et. al. [1].

In parts of the world, for example USA, Canada, Australia, Europe, other locations, serious parasitic infection are now not common. The immune system, which co-evolved with parasites over millions of years appears to turn on our own bodies because of the lack of parasites to attack. This hypothesis (the hygiene hypothesis) is investigated in the cited paper.

I referred to serious parasitic infections above because virtually everyone host some benign parasites such as the Demodex mite, a microscopic mite that lives on our eye lashes. See [2].

"Should only people with school-age children be allowed to vote on school board members?"

This is an obvious no. Apart from the issue of taxation without representation, not having children does not disqualify your opinion on education. There are plenty of taxpayers who are interested in ensuring that children get a good education at a reasonable cost who don't have kids.

People have been predicting Exxon's demise for at least 4 years now.

But look: it's not my claim that Exxon is a good investment. In fact: Exxon's stock seems to have tracked the prevailing grim sentiment about the oil business. Rather, what I'm pointing out is that it doesn't seem reasonable to suggest that Exxon is "functionally dead", a "phony-baloney" company propped up by paymasters in the rigged financial services industry. Exxon is, as a company... kind of important? Like, it does a bunch of stuff?

Another example: Boeing. We're all aware of a big reason for Boeing's predicament. But Boeing didn't get there by being a "zombie" that wasn't doing real business; in fact, we can probably ruefully say Boeing did too much business on the 737 Max product. So there's another reason you can be on the "zombie" list: your company made a huge mistake that will take years to climb out from.

Moderna was also on the list Taibbi linked to. Because it was an R&D company that wasn't meaningfully shipping product. I don't know that we even need to talk about Moderna's financial prospects (I genuinely have no idea what they are) to dispose of the idea that it's a "functionally dead" "phony-baloney" company; it's a key, effective component of a strategy to rescue the world from a global pandemic. So there's yet another way to get bucketed as a zombie: you can be a startup.

My point --- I was too lazy to type it last night and am too lazy to come up with a way to say it succinctly now, sorry --- is that Taibbi is either taken in by or preying on a layman's understanding of the word "zombie" to drive a column about how 1/3rd of the market is kayfabe. There is probably a way to make that point, maybe without even having to argue that Ford Motors is a fake company. But Taibbi tried to make it by linking to an article that calls out Tesla and Moderna as examples of the "zombie" phenomenon; he either hasn't read his link, which basically refutes his argument, or he's assuming you won't. Because after he writes that link, he goes on to imply that "zombie" means here what a normal person thinks it means. And it does not.
Nope. The question was whether it’s worse (in terms of recovery time) to crap on the SEC or your customers, and in which case you’ll recover faster. Elon frakked with the SEC and rightfully had to pay a price for it. But they recovered quickly. I don’t think Robinhood will.

The best thing is to not frak with either the SEC or your customers. And that’s probably always an option, even if it might mean sacrifice.
The rules were written, and have been interpreted with certain perceptions of 'who is deserving'. To claim that they weren't is at best ignorant.

extreme stock price volatility has the potential to expose investors to rapid and severe losses and undermine market confidence

It's not the SEC's role to protect investors from risk or losses, rapid or otherwise, and saying that the recent activity "undermines confidence" is just another way of saying "increases risk", which is not their job. They should ensure confidence by guarding against fraud, but not to protect against losses by institutions that never thought that activist investors would work against their own interests.

This isn't really manipulation that we're seeing: it's people betting against the institutions that themselves bet against companies combined with a fair bit of FOMO.

> No, not all Robinhood accounts are margin accounts,

I don't think I said that; I said that Robinhood papers over the differences in a way such that the end user doesn't explicitly interact in a hugely different way, and it's not explicitly clear what kind of account you have.

I did imply that new accounts are all technically margin accounts. The link you provided seems to prove that?

> When you sign up for a new account, you’ll automatically start with a Robinhood Instant account, which is a margin account.

> 2. Yesterday, all Cash accounts were disabled from trading GME

Yes, but I didn't say that this was because they were "margin". I said that this appears to be because Robinhood, as the broker, still requires additional cash on hand to cover these positions until they settle. This is a different thing than the margin issue.

> 3. Trading with a margin accounts and trading on margin is different.

Yes you're right. But a new user that just signed up may be thinking they are using a cash account, but it's actually a margin account. It also appears that you have to manually downgrade from an "Instant" (margin) account, to a "Cash" account[0], and I highly suspect that most people didn't do that, and thus are still using a margin account.

Not hospitalized does not mean no damage, short or long term. That is not to say this vaccine is a bust, but I for one was disappointed in the efficacy. The Novavax vaccine appears to be better and is also able to use existing supply chain technology.
If they process an order 'late' the price change could swing in their favor and they would end up netting the difference. FXCM got caught for this in FX years ago, skimming fractions of pennies off the trades for millions in profit. I'd be interested to know if those late trades always went in one direction.

We're limited by supply, so the existence of (limited quantities of) better vaccines isn't a good reason to block people from choosing to get a safe vaccine that still provides a reasonable degree of protection.

There are plenty of people in the lower-risk categories who would prefer to get a >60% effective vaccine now, rather than wait months for their turn in line for vaccines with the highest efficacy.
>I am so sick of this 'stay in your lane' attitude.

And I am so sick of the HN-trademark "I'm smarter than the average bear" arrogance that you display here. Pick an article about nuanced subjects like COVID vaccines, the 737 Max, the law in general.

CLI version of gdb has worked extremely reliable for me across multiple projects and architectures (x86, arm, arm64, etc).

I have yet to encounter a bug can't be debug with gdb with some test automation + gdb script with conditional breakpoints / hw breakpoints. As long as I can reproduce the issue with test automation, I can debug it with gdb.

Most complex bugs are I have to debug was multiple threads (20+) memory leak shows up after days of testing.

I don't use GUI gdb. cli + gdb script is the best and most reliable debugging environment. I don't add printf to my code anymore, a new gdb breakpoint script + with proper debug build can replace the printf anywhere and anytime.

We've been playing a fair amount of Kingdom Builder (whereas normally we'd play longer games of Terra Mystica or Through The Ages that would definitely not quality for this "under an hour" constraint)

I think with five players an hour is pushing it for Kingdom Builder, but of course this will vary if you've got players who are just generally faster at playing board games.

Note that the boxed Kingdom Builder game is actually four player, BGA is providing a five player expansion (because it's a web site, so the extra little wooden pieces don't cost anything) but if you are in the real world that's an issue for five.

I feel like Stone Age is a better introduction to worker placement than Puerto Rico but I wonder how often you'd really get a five player game in an hour. We generally take 90+ minutes for four players.

I recommend you read the update notes. In particular the multi-threading solution to belt management is an interesting programming problem that many games just get wrong.

As to your assertion about the game play of Factorio, it is not mine, craft, and place like in a normal RTS. In order to succeed at the game you must design which is a far cry from base building in StarCraft II, for example. Blueprints are indicative of this design requirement.

There are games where you design ships and save templates for them. But playing Factorio all the way through is a much more complicated experience than movement and crafting. Unless your assertion is that complexity of gameplay is measured by input mechanics, which I think is demonstrably incorrect.

I think what continues to surprise me (after talking about these for months now) is his underlying assumption that the third choice is a likely option. While the continued rate of spread seems to suggest to me that really we have a near binary option:

1. get injected with some vaccine soon, expose your body to a controlled amount of slightly noxious chemicals and hope your body learns how to eliminate them before they degrade on their own

2. contract COVID-19 soon, expose your body to those same noxious chemicals, plus a bunch of others that help it spread throughout your body and cause damage and linger, possibly for weeks or sometimes until you die

(excluding extreme options, like living alone for the next 5 years far from other humans, or dying of a mundane cause sooner)
