> This practice meant that trades placed on Robinhood weren’t executed at the best price, costing customer tens of millions of dollars, even after taking into account the savings from not paying a commission

This is why I stopped using them last summer. They messed up a few of my trades. Either by giving me a worse price than was quoted or my reversing the trade after it had already gone through.

After it happened a second time in a short time frame, I knew something was up. I closed all my trades and took all my money out.

What's really weird is that these "errors" started happening only after I started making good trades. When I lost money on a trade (which happened a lot for the first few years of casual trading), I NEVER had an execution error. Then, when I had my first good run of trading in years, all of the sudden I had TWO trades messed up within a week of each other???

It was all too conincidental for me. Either they were messing up my trades because of incompetence or they were letting someone take the other end of my trades.

Whichever it was, I left.

Robinhood had an insane run of good press and was able to within years of crap product. Now they are finally getting what's coming to them.
>he mesmerises the audience by telling them what it's like to grow up black in America not even knowing you're black, until one day, as a young child, you catch yourself in the mirror and realise you aren't the person your culture is built for. You actually don't exist, because there is no space in your culture's stories for you.

This seems like a pretty obvious and unsurprising consequence of descending from people that were only brought into that civilization to provide slave labor. How many civilizations have made special effort to reshape their culture for the benefit of the descendants of their slaves? I think anyone that appears "mesmerized" by hearing that probably has not thought very much about the topic, or is putting on a show.
When I did my Oracle DBA training 15 years ago, I learnt about database reorgs.

It means basically exporting your database (or tables) and importing it again. What happens is that deleted data which doesn't necessarily free up space (Oracle reuses the freed up space sometimes) doesn't get exported.

A simple solution would be to turn the 3-day settlement period into 1-day, or 0-day. But of course, DTCC has all the incentive in the world not to go along with that.

The trouble is that the 3-day period is a "leaky abstraction." It's the sole reason any of this became an issue. It's not a law of nature that "DTCC must insure 3 days of risk."
C#'s development was motivated by their relationship with Sun, but J++ was MS's non-conforming Java implementation. They were sued for it, and basically couldn't develop it any further (with regard to maintaining Java compatibility, to the extent that they cared to at least).
Those issues aren't generally actually due to NULL bytes in strings, but rather due to treating UTF-8 strings as C `char*` (or other mistreatment of "compatible" encodings). C code cannot handle UTF-8 strings as `char*`, even if you've got a UTF-8 locale (eg `LANG=en_US.UTF-8`). You have to convert multibyte strings to wide character strings (eg using `mbrtowc` to get a `wchar_t*` and then operate on that. C has multiple string types, no good type safety for them, and confusing them leads to vulnerabilities.
> You can drive the price down simply by inflating the supply

short selling does not increase the number of shares. if i borrow a share from you and sell it, you cannot also sell that share. the number of shares is constant regardless of how many shares are sold short (except for naked short selling).

short selling increases the number of people that can sell, but that only increases symmetry in an otherwise asymmetrical system. anyone can bet that the price goes up, but without short selling, only people that already bought can bet that the price will go down.

> there's always going to be a perverse incentive to target any company so long as you can manipulate the supply enough to force a price drop

what is "manipulative" about selling a stock? if i buy a bunch of stock (to make the price go up), is that also "manipulation"?
Their concern is poor user experience when the documentation on the web doesn't match what versions are being redistributed by other folks.
Some lessons I took from this retro:

- Disable autoscaling if appropriate during outage. For example if the web server is degraded, it's probably best to make sure that the backends don't autoscale down.

- Panic mode in Envoy is amazing!

- Ability to quickly scale your services is important, but that metric should also take into account how quickly the underlying infrastructure can scale. Your pods could spin up in 15 seconds but k8s nodes will not!

Keep in mind that the original goal of the Raspberry Pi foundation was directed toward education.

Raspberry Pi has inspired a lot of people to get their hands dirty with Linux and embedded systems, even if it’s not the optimal device from a pure engineering perspective.

In that regard, I’d call the Raspberry Pi a resounding success.
"not entirely an insult" sorry this is a lame excuse, it's offensive. it's a word used to demean no matter what context. To them its funny, it's not. typical bunch of men who need to show their hyper masculinity with insults and chants of "hold the line". are these the same people that call themselves patriouts.

But the user is the one paying - they get a worse execution than they could have gotten. The difference is split between RH and Citadel. The user does not have to shell out cash per transaction, but they will pay for the service one way or another.

As a screen reader user, automatic language switching is the first thing I disable. A lot of HTML templates just include 'lang="en"', and developers rarely notice that, even if their website is in another language.

I find Gemini pretty accessible overall. There are no images, so including alt descriptions isn't even a concern. There's no CSS, so you can't make controls that visually look like check boxes, but are much less accessible. In fact, it's way harder to make an inaccessible Gemini site than to make an inaccessible website. The only gripe I have is the possibility to introduce ASCII diagrams, which usually aren't accessible.
And what about just using BudgetML, which is free and open-source ;-) cheeky grin :-P
As a potential consumer of this kind of data it would be valuable to know how much of the US you can cover. If the revisit rate is every 12 days, do I get all the US every 12 days? What if I want it all at a lower resolution?

My suggestion is to have different verticals on the product page and to show specs from their perspective. One for the hedge fund counting cars in parking lots, one for the cops trying to find a missing person, one for the amateur sleuths investigating crop circles.
> more likely just other rich people and hedge funds.

I have at least two friends with absolutely no experience in any kind of investments who installed mobile trading apps and bought GME shares a few days ago at $300+ a pop

I'm fairly certain that a lot of people who are far from rich are buying GME stocks right now because a lot of other people are telling them the stock will "likely go over $10k a share" (I've seen it on the wsb subreddit a lot).

FOMO is a serious thing, low barrier to entry + constant media coverage = people want to be part of "it", even if they don't know what "it" is, especially when you tell them they could get rich.

Concrete example: for my latest side project, I chose F# because it was the most compelling (to me) language with a decent option for cross-platform GUI that isn't Electron. (Avalonia.FuncUI, which has a nice Elm-y feel.) The reason it had a good cross-platform GUI library available in the first place is very much because it lives on .NET, and can build on of the rest of the .NET ecosystem.
The key to remember is it's not the same basket of household items - they provide for substitution. Apples are too expensive? Maybe they'll be replaced with grapes. Beef is too expensive? Maybe it'll get replaced by chicken. They substitute items in such a manner to keep the inflation index as low as possible. That's important because social security checks are adjusted based off that inflation index so they're motivated to keep it as low as possible.

As you can imagine people claim this doesn't reflect true inflation as we're not necessarily comparing apples-to-apples (ha!) and it also excludes energy costs.
Age, maybe? Primary cause for fractures nowadays is osteoporosis, which AFAIK is more serious to women after menopause. Primary cause historically was accidents, with the opposite distribution.
Seatbelt laws are not the analogy I would use. It's direct physical bodily harm vs some unknown and unquantifiable risk when installing a 3rd party app.

We got by just fine in the 80s and 90s without App stores. So much innovation came out of that world which established the dominant players who are in control now.

And you don't even get security with App stores. As we already know with all the malware found in Google Play apps.

App stores are simply keeping the big guys big and small guys small with few exceptions here and there.

It's just another walled garden that keeps the little guy out and keeps players like Google and Apple entrenched.
I'm late to the party. But this seems to be a policy problem, no? There needs to be a real incentive for Apple and other platforms to prevent this scams.

Off the top of my head, I wonder if you couldn't make Apple have to pay a flat fee and all revenue made from the scam to the lawyer proving that this is a scam. That would create a merket for anti-scam lawyers, resulting in quickly hunting down all scammers on the platform.
Perhaps for some here (including myself) this data helps imagine a more detailed approximation of what life was like there in that time period.

When the stock crashes, you can sell some bonds, which have not crashed, and buy stock on the cheap. When the stock recovers, you sell some stock and buy bonds. Rinse and repeat.

Habitual use of Vitamin D supplements and risk of cCOVID-19 infection
I'm sorry that this conflicted with your plans, but I feel strongly that distributing Python libraries via system package managers such as apt is very bad for users. The pain is felt especially by users who are relatively new to Python, who will end up with their system Python in a confusing state that is difficult to correct.

We of course encourage anyone to clone the repo or install from an sdist if they want to compile from source. In fact you can do the following:

git clone https://github.com/explosion/spaCy
cd spaCy
make

This will build you a standalone executable file, in the pex format, that only depends on your system Python and does not install any files into your system. You can copy this artifact into your bin and use it as a command-line application.

>The article is a bit confusing. There's "PFOF" which is basically middle-man profit taking.

Not really. The middle-man profit taking (aka market making) will exist even without PFOF, it will just move onto the open exchanges. The only difference would be that the market makers would have to offer worse spreads because they can't separate "dumb" order flows from "informed" order flows. This is an overall negative for retail traders but a net positive or neutral to hedge funds/institutional traders.

Yes but there's a counter to this and limit that is not there on the long side: Remember stocks are ownership in a company. If a load of "predatory shorts" jumped on and drove the market value of a company way below of where it should be, I could jump in with sufficient money and make a tender offer. Then I'd own a real company with real assets for a fraction of the cost and take it private. And the shorts would have to cover their shares.

There's no such reality check with things going up on the long side as we see from Gamestop. Someone can't step in and cash out on the company at a ridiculously high price compared to fundamentals. It is only driven by the market. In general short sellers are vilified more than warranted. If you are long on a good company you should applaud them because after all, they now have to buy back at some point. People view it as if you are some villain going against what is right (shares just going up and everyone gets rich). Stocks that go down with high short interest are almost always going down because they are bad companies, not due to short sales.
One of them has already worked on the so-called "dark side". I doubt they are going to refuse sales to anyone unless there are ITAR or sanctions involved.

The big takeaway for me here is that this “provisioning service” had enough internal dependencies that they couldn’t bring up new nodes. Seems like the worst thing possible during a big traffic spike.
So why didn’t you detail this?

And what market maker has not been fined for rule violations before? How is this pertinent?

We know the DTCC raised the collateral requirements by 30x for GME. Does Ken Griffin own the DTCC too?

We know Robinhood suffered a cash crunch and was required to raise an emergency $1B. We know that every GME purchase by its customers increased its collateral requirements, and every sale reduced them.

Don’t all known facts directly explain Robinhoods behavior? Wouldn’t Robinhood simply move to another market maker if Citadel got out of line?

Does anyone know that Ken Griffin made any demands of Robinhood?

So why are we pursuing baseless conspiracy theories when the facts already explain the behavior?

Guardian(2004): Britain will be Siberian by 2020
I've built such strong relationships through games, with people I've never met, that I can't agree more with that.

The limit is that games will have the same effects as other "offsite" activities. Some people will be into it and it'll work for them, but others will just not be interested (whatever their reasons).

For example the first picture of the article shows basketball. That could be seen as a great team building exercise (for non-remote teams) but some people just don't like basketball or sports.

Unfortunately there are no silver bullets.
I had this happen with Rust. My Rust code as a beginner had a bunch of smells like unnecessary copies, overly verbose code, etc. But in the Maslow hierarchy of programming, working code is a prerequisite for idiomatic code. Better to write some bad, working code and slowly turn it into idiomatic, working code.
So let them exit then. It's not like Google has the right to set prices for themselves.

It's similar to Germany where, i.e. book prices are fixed, and every store must sell for the same price, whether they like it or not. Of course, they have a choice not to sell.
I mean, when the hammer manufacturer sells managed, auto scaling thumb-avoiding services you might rely on that.

The results and conclusions here are rather interesting:

> Results

> After adjustment for covariates, the habitual use of vitamin D supplements was significantly associated with a 34% lower risk of COVID-19 infection (OR, 0.66; 95% CI, 0.45–0.97; P = 0.034). Circulating vitamin D levels at baseline or genetically predicted vitamin D levels were not associated with the risk of COVID-19 infection. The association between the use of vitamin D supplements and the risk of COVID-19 infection did not vary according to the different levels of circulating or genetically predicted vitamin D (P-interactions = 0.75 and 0.74, respectively).

> Conclusions

> Our findings suggest that habitual use of vitamin D supplements is related to a lower risk of COVID-19 infection, although we cannot rule out the possibility that the inverse association is due to residual confounding or selection bias. Further clinical trials are needed to verify these results.

I'm a little puzzled why taking vitamin D supplements was associated with lower risk of COVID infection, but vitamin D levels were not. This suggests that vitamin D might not do anything as a post-infection intervention.

It's also important to note that this was a prospective study, meaning people were enrolled before they became sick. So, they're not just using data from sick people to correlate vitamin D levels with outcomes like many other studies have done.

>A simple solution would be to turn the 3-day settlement period into 1-day, or 0-day.

Unless you cut the settlement to 0 the issue will remain. The fundamental issue is that 1) deposit is required, 2) there's a spike in demand/deposit requirements, 3) current reserves can't pay for deposits. Going to 1 day settlement will just cause brokers to reduce their overall reserves in response (no need keeping all that money around!), so the next time a spike occurs the same issue will occur.

Taking walks around the neighborhood, I've stared to notice just the sheer number of these cameras. It bothers me that I end up on probably 10+ doorbell cameras, possibly showing up as an alert on someones phone.

I live in a suburb where basically nothing ever happens. Sure, there's the occasional clip posted on nextdoor of a rude driver or some kids stealing a lawn ornament. But I highly doubt that the grainy unfocused video of a doorbell camera was ever pivotal in solving these crimes.

I just don't understand why so many people want to record the front of their house, and pay someone like Amazon a monthly fee to do so.
I was wondering the same - I've seen gotenna stuff sold at REI and other outfitters. Meshtastic makes the claim that the gotenna project is focusing on enteprise deployment and not end user (plus the usual dig that it is closed source). Though the gotenna webpage still has the personal mesh devices for sale.

Meshtastic sounds like an open source alternative, but if you have to built your own device I don't see it growing beyond serious DIY.
You make it almost sound like having a fractured eco system with two different incompatible async frameworks is a good thing! :P

As a consumer, I will still pick Intel + Nvidia. This stuff (mostly) just works.. Even without drivers

AMD can just work, but most people who have problems with new hardware are the AMD users. It comes mostly down to software support, drivers and BIOS configuration.

Another example is that every 'fps performance guide' always included a big section just for AMD users. It's just too finicky.. Always has been.

This still makes me shy away from AMD and just spend the extra few bucks.

not surprised games bring bond happiness and laughter which can cure cancer, but the problem is a lot of games have fragile net code, you sometimes have to rely on the "big" online multiplayer games cuz a lot of indie / small games prob won't work or can be frustrating to work with.

If what he says is true - - - then he should have put the word immediately on the front page of his trading app that it's the financial watchdog agency that crushed us with a new, unexpected margin requirement for money we did not even possess at the time, so we were forced to shut down trading in certain stocks in order to keep our system even functioning at all . . .

Robinhood's ethos is reportedly: “Let the people trade.”

But in reality it's just another electronic brokerage, and 95% or more of daytraders are loosing money trading.
