> RH is not allowed by law to use their customers' money as collateral to DTCC. If RH goes broke, then DTCC does the following:

I still can’t find an authoritative citation for this, and it seems seems like poor design to me.

Suppose Robinhood has one customer. That customer opens a cash trading account, deposits $1bn into it, waits for the deposit to clear and waits an extra week for good measure, and then uses all $1bn to buy an absurdly volatile stock.

Now, between the execution of the trade and settlement, Robinhood is apparently holding $1bn (in a segregated account?), and Robinhood needs to post some largish fraction of $1bn with their clearer to offset the risk that Robinhood fails to pay the $1bn at settlement.

To me, this seems like un unreasonable requirement for Robinhood. If their actually go bust before settlement, they owe DTCC, etc $1bn, the customer has $1bn deposited (in the same segregated account), and the customer is owed some number of shares of the stock. All the money is there!

So why can’t Robinhood satisfy its clearing fund requirement by putting the appropriate fraction (or even all) of the customer’s $1bn into segregated account with its clearer? After all, the mere fact that Robinhood has a whale for a client does not mean they are any more likely to go bust, except for the fact that “bust” seems to include this odd case where Robinhood can’t independently secure its customer’s trade.
I had that one for a bit, it felt really low quality and not very comfortable (at least for my hand shape).
Does anyone have any idea how big the fan base? Obviously not GoT-levels, but big enough to warrant 6 seasons.

The show has some polarizing aspect to it, about half of my friends are really into it (me included). Half my friends bounced off the first couple episodes.
The show's going to end with the next season, before they hit the final three books. That's probably a good thing, considering that they jump three decades for the last segment of the book series. They haven't ruled out that they won't return to it at some point, though.
Theoretically yes, see e.g. the calculations here youtube.com/watch?v=no_q6sJXjm8

Yes it would absolutely be issuing new stock.

However I'm actually not sure how quickly companies can do that. It has to be done by the board. Can they just hold an emergency meeting and authorize it within hours? Or is it the kind of thing that requires certain approvals which require weeks or months?

It could also be a huge PR backfire. If the stock then drops back down, then they could be accused of taking advantage of naive redditors -- not that that's necessarily true, but there's definitely risk of it. I mean, is that what a "responsible" public company is supposed to do?
I think most environmentalist are just very anti-growth and just want to solve environmental issues by reducing any resource consumption. By saying no to nuclear they are fulfilling their anti-growth strategy, but leaving a large resource gap that gets filled by more polluting, less dramatic energy sources.
Echoing other responses, I've found that trust is a hugely important dimension of effective teams. In a technical setting, there is a key benefit to trust. Do you trust your mates enough to share an idea that you feel is probably stupid/lame, but might have some seed of value in there somewhere? New ideas that initially seem "off the wall" may lead to important breakthroughs with some nurturing and reformulation. I've also experienced a sort of team-level flow, in which an idea triggers a variant idea from someone else, and then another and another, and collectively you end up with an idea that feels like an emergent property: you end up with something really good that no one could have gotten to on their own, that represents something greater than the sum of the parts.
In code we trust, and code is law.

The good thing smart contracts are inspectable, so there is at least the open source aspect to help mitigate concerns.
Well, COVID showed us that it's not just that stuff gets to your house in 2 days (rather than 3!), stuff gets to your house in 2 days even during worldwide pandemic with widespread supply chain disruption.

Also, starting an online business is easier than ever due to democratized access to infrastructure that was once only available to large blue chip companies with access to 1000s of high skilled engineers, and has seeded an industry of small/medium sized tech companies that has resulted in further consumer surplus and wealth creation.

Not saying that there's an obvious "correct" point of view, but once you add a little more nuance, it actually does make everything worth it for a lot of people.
It certainly should be, and this is no problem in developed democracies. Not so much in the developing world - leaves room for corruption.

C++ expression-power has increased considerably since C++11, and I believe, semantically, Prime Number generation in both C++ and Python could be python-line for c++-(line[s]) translated.
C++ approaching the comfort and ease of use of Python is a worthy goal to reach.
The flip side is well appreciated too (Cython, where Python can converge to C++ performance is noteworthy as well).
If the free software solutions are better then by all means, go for it. I never suggested that proprietary was better than free.

My point is that arguing that the choice should be made on the free software status is a bad idea.

Choose software based on the best tool for the job, not the ideology behind it.

You need an account with a broker to see prices with sub-minute resolution. If you need that, you likely trade seriously, and have more serious tools from a broker or two anyway.

But if all you want is to watch trends, not do HFT, being even 5 minutes late is fine. Even just looking at how a day went after hours is fine.

It depends what form of gambling you're referring to.

A blockchain based roulette smart contract could provide absolute transparency to anyone placing a bet. The exact process which determines the outcome is known, and it cannot be changed. The assurance that you get your money is the smart contract.

A smart contract based prediction market, such as Augur, can offer similar transparency. You have the assurance that, should the market be resolved in your favour, you will get your money. The main concern is the governance structure which determines the outcomes.

I think this feels like an underestimate of the performance difference? I generally keep in my head that C/CPP is roughly 100x faster than python, and the computer language benchmarks game seems to support this (I admit that the solutions on there are uncharacteristic of idiomatic code in many cases but hopefully the python and CPP solutions are equally horrible there).

https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

I wonder how you can characterize the difference in speed between the two languages. I think I read somewhere that in the reference implementation of ruby, calling a method in the general case can require several hash table lookups to find the implementation associated with the name of the method. Is that mostly the same in python as well?
GME was just done for laughs. A hedgefund lost 53% of its investment in the process. That's the reward you got when you bought GME.

It is absurd black and white thinking to declare that anything which reflects its source culture is propaganda even if it embeds the bullshit influnces of propaganda of the day like the classics obsession of the Enlightenment.

Calling a work propaganda merely because it reflects a source culture is propaganda in itself.

That has been used by amongst many others evangelical fundamentalists and the Party in basically every nation which called themselves Communists.

> Barr signed off on a non-prosecution agreement...required Smith to admit he had committed crimes, pay $139 million and cooperate against a close business associate indicted in the largest tax-evasion case in U.S. history—Texas software mogul Robert T. Brockman

Prosecutorial discretion is a tricky thing to judge. On one hand, it's a black box. On the other hand, it has to be. It's a human judgement around which investigations are worth pursuing given the facts and circumstances, the law and the will of the polity.

Within the confines of the rules, this looks...fine? It sounds like Smith was fined more than he aimed to save. And if it bags a bigger fish, particularly if with jail time, it seems like the trade would be worth it. At the very least it makes tax evasion riskier going forward--your billionaire co-conspirator is now a real liability.

Without knowing the odds around that case, it's difficult to judge this decision.

It should maybe noted that all operators in Raku (excapt the short-circuiting || and && and friends) are in fact "user" defined operators. They just happen to be defined already every time you start a Raku program. But code-wise, there is no difference!

Re operator overloading: you could argue you could also do that in Raku, but generally it is about adding functionality. See e.g. the Interval module, which adds "interval" knowledge to the standard DateTime object. It also adds functionality to the + and - infix operators. See: https://modules.raku.org/dist/Interval/lib/Interval.pm6

The problem I have with this is that it makes people create and manage an account. My 90 year old grandmother is not gonna manage that.

I made a little hack for wordpress that lets you run a wordpress blog and have a shared security question that lets people access content. A simple question like "What is the name of the family dog?" or "What is grandpa's nickname?", something like that. Not industrial strength security, but enough to keep it sorta private and out of search.

The nifty part is that with wordpress and Jetpack, people can sign up for posts by email, so every time you post, your friends/family can get an email with the updates. No need to even visit the blog. Perfect for grandma.

Here's the two files that make it work, in case anyone is interested:

The entire operating procedure of security exchanges is a series of terrible ideas that exists in it's current form because it allows the most wealthy participants to maintain advantage. Latency arbitrage shouldn't exist, as one example. There are no sound explanations of why it must be allowed, which leaves greed as the only plausible one. We dedicate a lot of talented people and expensive equipment to fleecing each other at high speed when there are better problems to be worked on. On a societal level it's idiotic.

I'm not from the US and I got "free" education where I live, and I still feel like I've lost money.

I don't feel like I've learned anything substantial that couldn't be covered by a short online course, but I sure spent much more than working hours stressing out and torturing myself with absolute garbage topics.
> Half my friends bounced off the first couple episodes

The show starts off quite slow, which is probably its biggest "weakness".
The popular theory you see in r/TheExpanse is that S01E04 is what hooks you on to the series. The first season is indeed a bit slow, but seasons 2 and 3 really take it up a few notches and are fantastic.
To create change, make the change easy.

If FSF wants school administrators to change their behaviour to stop using proprietary software, they'd need to make that change easy. If _they_ say that free software is too hard to install/use/manage, then the FSF can either:

A. Call that an excuse, which is a path of mutual distrust that will block change.

B. Listen more deeply to their underlying needs, then change their software to meet those needs.

C. Option B, then listen to themselves to understand what would make it easy to make that change.

I haven't checked the details yet how it determines that you are in an ssh session.
The fact that Robinhood had to emergency-raise $3billion to be able to put up the collateral with their clearing houses should be enough indication that a lot of retail traders were engaged in these highly volatile stocks.

> Goroutines don't map directly to OS threads though, do they? So in practice it only matters for "hard" threads.

It matters for goroutines because that means you can't straight call into foreign code from a goroutine's stack, which is why cgo and friends are so problematic.

> Also the default pthread stack size is (usually) 2MB which is indeed non negligible if you have a ton of threads

That's not relevant because it's not vmem is the point. The actual resident size of a 2MB stack is 4k unless you start dirtying more pages. Unless you're running on 32b, VMEM doesn't really matter.

There isn't a robust economics argument for advertising. We're dumping a bunch of economic resources (lost otherwise productive time) into an industry that serves to distort free markets.

There are claims of letting people know about products, or "driving consumer demand," but they fall apart as you dig deeper.

It's not clear how it ought to be regulated, but it ought to be regulated. It ought have been regulated a long, long time go, actually. When banner ads popped up on the Internet in the nineties was a much easier time than 2020, when we have trillion-dollar businesses pushing back.
