AM I the only one annoyed by plotnine arbitrary use of abbreviations?

Some are slightly more excusable, like aes instead of aesthetic, but given today's editors auto-completion, I find this kind of choice annoying by making the code less readable for new-comers.

But others are more gratuitous to my sense. For example, the colors gradients. 'Blues' for blue gradient, but GnBl for a gradient going from green to blue? How hard is it to type Greens-Blues? It also makes it harder to remember which are abbreviated and which are not.
Of course they could, but it wouldn’t help people so why bother?
Well, I'd assert that every system fails eventually. And it's a pretty common practice that you deal with these failures by implementing a redundant system that can take over in case of a failure. Think about drives in a drive array, or redundant web servers behind a load balancer. This is just the same concept applied in the large for an entire cloud workload.
I sure hope that GameStop or whatever companies are affected that their corporate employees aren’t in a sell blackout period. Usually you can’t sell for a few weeks before earnings are released. If you’re just a paper pusher, I would consider taking a slap on the wrist.
> Hertz was within a day of issuing more shares before the SEC told them to fuck off

Your timing is off, Hertz was selling shares in the morning, and stopped when SEC called them. They stopped selling promptly, but not before "Hertz Global issued 13,912,368 shares under the ATM Program for net proceeds of approximately $29 million"

https://www.sec.gov/ix?doc=/Archives/edgar/data/47129/000165...

Gamestop already had an ATM offering they registered for in December; I'm awaiting the news of what price they sold at with popcorn at the ready.

I believe throwawaysea's point is that the one thing has nothing to do with the other. Essentially, the bank weighing in saying "We don't believe your customers are good for this amount of money you claim they are good for." is, at heart, just financial prudence on the part of a trade's 3rd party backer. The other is criminal collusion on the part of people on the other side of a trade. But the 3rd party backer doesn't care about any of that as horrible as it may sound. They just want to be sure they can get their money from both sides, and they're not at all sure about that with these GME/BBY/AMC et al trades.

This list is trying to make a point, but it’s not very good at it.

To start with: many of the things are objectively outside the bounds of what’s generally regarded acceptable. Someone opining that COVID is a „liberal conspiracy“ is objectively unfit to engage in the sort of reasoning research requires, and a waste of students‘ tuition at best. Objecting to the very idea (Not any specific issue) of engaging with ethics in AI is just as disqualifying as it would be in medicine. Being happy about bloodshed is just lame, as is the „I was hacked“ excuse. Being happy about some cops‘ violent deaths is just as unacceptable as any other innocents‘ murders.

Some items lack the specifics to evaluate them. I could imagine the authors here might be hiding some rather objectionable statements behind phrases such as „supposedly made insensitive statements“, considering they felt the need to repeatedly put scarequotes around „racism“.

Then, when you click through to the sources you’ll find actual cancellations are rather rare. That ethics guy is a retired professor, and this list is taking issue with the simple fact of him being criticized for his criticism. Some items are about „open letters“ in student newspapers expressing criticism, not even asking for dismissal.

A number mention the person in question being placed „on leave“. The vast majority of those instances will resolve with consequences short of dismissal: some training maybe, docked pay, or nothing at all.

Sure, and all of that cashes out in an equilibrium, called marginal pricing. There's no breakdown in the notion of value here. Nothing incoherent about it.

Robinhood and the Two Citadels
> My laptop runs Arch - that's far more friendly than anything I used in the '70s-'00s.

Not to be too much of a Linux-using stereotype, but it really does seem like the things that have been getting better are those things that are made (usually for free) for users for the benefit of themselves and other users, and not by profit-seeking corporations as closed-source software.

The few exceptions to that rule are those areas that are heavily dependent on technological improvements, e.g. music production, gaming, media editing. But that's just because there are still huge profit-wins to be had just by improving the quality of what the user receives. There's no reason to think wins like that won't dry up.
This would be a great justification to pause this trading for all clients. The challenge is they didn't limit access for institutional while limiting access for retailers. This discrepancy is core to the feeling that Robinhood is supporting the financial establishment over their community of traders.
How common is high blood pressure? About 1 in 5 adults.[1]

Effects of untreated high blood pressure: loss of mental function, atherosclerosis (so heart attacks and strokes), and vision loss are some of the big ones.[2] It's probably the leading cause of death these days.

So the market for a cheap, reliable and convenient diagnostic device is very large, and wide open at this point.

> 1. For the first 6 months you're paying a sr. engineers salary to get jr. engineer productivity.

Ouch. While I myself have been guilty of that 2-3 times during my sadly way too rich on customers and employers career, this is definitely the exception and something with your hiring filters is very wrong.

Combined with your disclosure that you pay about $200K but still have problems with good programmers then I'd think you are letting people in either way too easily or you don't aim well. Which brings me to...

> 2. While great devs are great, it's a lot easier to figure out if someone is a framework/language expert than if they are an intrinsically great dev in an interview. i.e. ("Do you know C# well?" is easier to determine than "Are you a good problem solver?")

I will respectfully disagree with the last assertion. You or the people who interview devs must reach outside of the usual leetcode / whiteboard tests and do some research on more general interviews and learn techniques through which you will get a very good idea if the interviewee is a good problem solver.

Trouble is, most tech interviewers view gaining those extra evaluation skills as a waste of time.

Piece of advice: give the candidate 10-15 minute and an easy coding problem they could solve in front of you, or give them a really small homework (not this "you'll need 1-2 days at home to solve this homework" nonsense) -- but don't make the tech aspect of the interview the dominant part. Talk with the candidate. Give them a few examples of tough situations from the past. Chat with them about how would they approach the problem(s). Ask them what they know about CI/CD, about best practices in framework X or Y, what project or task that they did makes them proud of themselves. Many other such great interview questions exist.

Not meaning any disrespect to you, you seem to be trying hard to get good devs. But from what I read here it does seem like the aim of your company isn't good and it's mis-firing the hiring gun.

$200K will tempt a lot of people to lie and "wing it" when they get hired. But you should leave the high remuneration in place. That way when you get a good professional they'll have one extra -- and very fat -- reason not to leave. :)
>Is it possible to build a tool or a technology that guarantees privacy while providing tools for investigators, without opening backdoors and without compromising legitimate use cases?

No. The answer is in the question. You can't have privacy if a third party can read your messages. You don't need to be a "cypher geek" to understand this.

>I know, it's a hard question

It's not.
Chicago's a very nice city. There are basically three main factors keeping the cost low currently:

1. Population decline.
2. A very large amount of good housing stock. Chicago's completely flat with solid public transit reaching out to the suburbs.
3. Lower proportion of tech and startups. Similar to how tech has driven up the CoL in many cities, the relative lack of tech in Chicago has kept CoL down.

Winter is rough in Chicago, but the CoL in Boston has skyrocketed which invalidates that as being the _only_ reason.
Will it impact faith in the market? No. It will absolutely cause people to think twice about Robinhood as a brokerage, but that is a small portion of the market.

I was able to trade GME all day on E Trade without a single issue.
The Many Functions of Functor
Well they sure made selling really easy during the architected dip.

Why allow so many new users to buy those positions before they blocked buys if this was coming? I mean, the prices were elevated before it got to this. Seems like a situation of let's ride the free customer acquisition and figure it out later.

They happily took the huge influx of new users that had no knowledge of this. And many got screwed. They couldn't average down on their position. And a ton of buyers were removed. So the price got out of control. Many panicked because of it.

I'm not on RH but added more at 170 and it came with several partial fills of 1 and 2 stocks. That was RH users getting screwed as a ton of buyers were removed. Trading was not halted on the downward spiral.

They could have said - hey guess what - 750k RH users (whatever it is) that own GME cannot buy this stock, so consider this before you sell. Some kind of warning that passed the attorneys. How could they not see this coming?

Any way it went down - RH is done. I hope they "pivot" into a worse situation.
A broker is just a service. As it turns out a low-cost/free service provides an inferior service to high-cost prime brokers.

You get what you pay for. That’s not a scandal. It’s common sense. It’d be like me complaining that it’s no fair that Google can afford better infrastructure than my startup search engine.

Day trading is not a human right. Anybody who wants trading infrastructure like Citadel is free to go out and spend the same hundreds of millions it took Citadel to build that infrastructure.
Good essay, but I wonder why the author does not mention Fortran in the section on Alternatives. Fortran 90 and later versions do have function and operator overloading, so it is may not be as clear as in Fortran 77 what a line of code does. But you can write modern Fortran (the latest standard is Fortran 2018, and Gnu Fortran supports much of it) that does not use these features.
Open Letter: Dear C3.js and the community from billboard.js
Both can be true. Citadel, the hedge fund that bailed out Melvin Capital (the hedge fund that over shorted GME) is Robin Hood's largest client. So it could be there was incentive for Robin Hood to ban trading on behalf of Citadel and they also don't have money to pay back the trades they make.
Healthy, ethical companies will sometimes combine the two. I'm sure that Tim Cook, as a boomer-aged gay man, has a very gut-level understanding of the importance of privacy: he grew up when being beaten up or even lynched for his sexual orientation was normal in his country, and where it was a criminal offense. The fact that the company he's the CEO can leverage "good privacy" to boost their profits makes for a happy combination.
Imagine a brokerage losing money when everyone wants to buy and sell like crazy. Sounds extremely mismanaged.
Not quite.

Policymakers care about outcomes.

No, naked refers to not having the borrow. More than 100% can be borrowed if someone buys it from someone who borrowed it and loans it to someone else. That's just short, whatever the percentage, not naked short.

Feature apparently influences what information you regularly see on Twitter
Background: I used Opera Presto as my main browser from 2007-2014, and Vivaldi since 2016 (2015 being a mix of Opera, Firefox, and Vivaldi). I've used Firefox as my main browser at work for most of the past four years.

One big factor for me is the customizability without having to rely on extensions. I trust Vivaldi (and von Tetzchner), and don't have to worry about whether I trust extension makers. The customization options in Vivaldi tend to work pretty darn well too, which can be more hit-and-miss with third party ones in Firefox.

Single-key shortcuts are also a big win for Vivaldi for me. I got used to these in Opera and they're great for efficiency while web browsing. Maybe I can get them with an extension for Firefox, but it's enabling one check box in Vivaldi. It's similar to why some people like vim plugins for browsers, but with less vim expertise required.

I've also seen Firefox remove a lot of features over the years. XUL extensions being the big one, but there are others. Firefox Hello. Firefox Panorama, just as I was starting to take a liking to it. Vivaldi has a philosophy of adding features that let you customize the browser to how you like it, and if only 0.2% of users use that feature but it makes them really happy, that's fine. Firefox will remove features if not enough users adopt it. Thus my trust that Firefox is going to keep features that I like has been lowered over the years, making me more hesitant to try new Firefox features, and generally more hesitant about Firefox.

Although I'm considering switching part of my home browsing back to Firefox because of its ability to not autoplay videos. Too many sites have those nowadays (and too often, self-hosted and not as third-party ads that are easily blocked), and Blink-based browsers can't stop them, and I'm getting pretty tired of having to pause/hide videos all the time so I can focus on reading articles.
Not really - in the case of Linux you pay the same price as OpenBSD but you get much more.

That's because enough people decided to put enough effort to support as many use cases as possible, until the OS got enough momentum to be hard to ignore.

The BSD approach has instead always been "you want it? then code it yourself and open a merge request". That sounds legitimate, but that's the real reason why OpenBSD has never taken off outside of its small niche of geeks - despite being an amazingly designed OS under the hood.

And I know many of those geeks who are quite proud of being part of a tiny niche that scuffs at Bluetooth, USB 3.0, QHD displays or anything that a "normal user" might want - had it been for them a 640x480 screen with a working session of xterm would have largely sufficed. But that's also the reason why there aren't many "normal people" using their OS.

At some point one should also ponder why we support and contribute to open-source projects (especially considering that we mostly do it in our spare time, that, in the case of developers, is often limited and precious). Is it because we want to make the (IT) world a better place with more free and cool products and attract more people, or is it because we like our own well-curated niche and we don't want to let anybody in?

As I read your comment, I had a growing expectation that you were about to express horror at the mass gathering and warehousing of individuals' health data. I was very surprised when you expressed such excitement at the prospect.
I’m a big fan of ReasonML. It’s the best combination of practicality and conceptual ideology. Yes, it’s functional, and encourages you to write pure logic that operates on values. But it also allows you to mutate state when you want. The type inference is also incredible, though similar to Elm and PureScript.
But blocking buying on the broker with the most trades = price falls down = real loss?
This is just an ad hominem attack.

It would take a bit more time, because stock certificates are a pain to handle. But I would let you borrow my stock certificates (for interest and with good collateral), you would sell them to someone; then that person might let you borrow them (for interest and with good collateral) and you could sell them to another someone (or the same someone, whatever).

Certificated stock is slightly less fungible than shares of book-entry stock; because I probably want you to return a single certificate with my shares, and you may have to separate or combine certificates which takes time and money. One of the many reasons certificated stock has been on the way out.
I made that point on reddit a month ago, and some wag pointed out that since I evidently didn't know IQ scores were a bell curve, it appeared I was in the lower half.
>And that would be neither here nor there, cause your forums are not so massive as to shape public opinion and influence elections and news.

Maybe assholes shouldn't be able to use these platforms to shape public opinion and influence elections and news. Maybe having a Twitter account is a privilege, and not a right, and that privilege is correctly granted on the precondition that one will not use the platform to act like an asshole.

Then again maybe we shouldn't elect assholes President to begin with, but that's also neither here nor there.

>When one side, in a major public-opinion-influencing service can ban a whole side of the political spectrum though, and even the sitting president, that's a problem.

Except the "whole side" of the Republican, conservative, or even pro-Trump spectrum hasn't been banned. I don't know why people keep repeating this when even a cursory look on any popular social media site will show that there's still plenty of that speech active online.
If you buy and sell shares within the same day three times in 5 business days, you will be flagged as a “Pattern Day Trader” and you’ll need to post at least $25,000 of collateral.

I don’t think the problem here was with too many trades. Very few Robinhood accounts overall have over $25k balance.

I guess I can’t see where the risk is. Shares are moving electronically between different ledgers as orders are fulfilled. Shares aren’t being created or destroyed, nor is money.

I can definitely see how you could end up with large net cash flows that need to settled over the next 48 hours, if Robinhood accounts are collectively gaining or losing huge percentages of their value from one day to the next. But I don’t see, absent allowing margin or naked options, how they could ever end up owing more than they actually have on hand in their custodial accounts.

I would possibly believe that Robinhood didn’t have the technical controls the fix the problem that they were having the “right” way, and had to resort to their “least worst option”.

For example they should have the technical controls to flag specific sales to prevent those funds from being reinvested until the particular sale settles. By free and clear settled cash should be able to buy any publicly listed share it wants.
