Maybe he is leasing it. Businessinsider does not have access to his personal account and neither does his company.

They couldn't even get Trump's tax returns. They have no clue.
Are you saying that life, liberty, and the pursuit of happiness is not important?
Sometimes I do, sometimes I don't. If it's an iterator I often use one letter names such as i, j, k. Similarly if it's a generic unbounded type I also give it a one letter name.
AWS has 40 billion in revenue, 12 billion in profit and is growing 30% YoY. It's got great profit margins, huge lock in, and is a natural monopoly. Not sure how much it would be worth on the open market, but wouldn't surprise me that it's 50%+ of Amazon's market cap.
I also don't think it's the 100% truth. First, I don't understand why you couldn't buy just some stocks. If RH really had not enough money, you couldn't buy any stock. Second, when you buy stocks on RH or any other exchange, you have to have the money on there on the account. So the money is there. There is no risk on the long side at all. Third, RH was not the only one, suddenly several exchanges have the same problem at the same time .. no I don't think so.
I think that the early oxford trials reported infections from day 1 of the shot, later reports are talking about what happens after 21 days.
You would think so, but probably no. I'm not someone that directly cares about the many inter-Tuscan historical grievances, but when I leave the Florence area for, say, the nearby province of Pistoia I feel more in foreign land than in London or Berlin.
That's kind of sad. I feel somewhat related to this: I was 1st developer of a startup (outside of the US) and at that time I was super close to the CEO. After leaving we kind of grew appart which is a bit sad because I consider him a really good person, and I still own stock in the startup. Of course, absolutely nothing compared to Amazon (hopefully at some point it will... we always said that we wanted to be the Amazon of Financial services)
Do you think blackberry is ever going to hit a price of $28 again short of a market dynamics play like a squeeze?

Break even price? Through what, innovation? Currency inflation?
Interesting explainer I saw by an Australian economics YouTuber (opposed to the new law):

Early Macintosh systems had several such fonts, including Cairo and Mobile. The icons in those fonts were a lot weirder than Wingdings or Dingbats -- where else can you find a font which includes glyphs for a fried egg, an ankh, a frog, and a dogcow?
Also curious myself..
The world is full of wasted motion
Humanity improves by improving forward, not by changing the meaning of historical events.
Probably due to the coming wealth tax or capital gain tax changes.
Then again, mocking and taunting people for using X11, which works great for most people, repeating all over every social media outlet that “X11 is dead use Wayland LOL,” giggling about how once IBM pulls its developers from X11 that “nyaaa nyaaaaahhhhh you’ll have no choice” and other poor marketing decisions, apparently conceived by obnoxious children, have convinced many people to NEVER touch Wayland with a ten foot pole.

It’s like the System D shills - they are HYPER obnoxious. I don’t need software made inside IBM, and I don’t need software which apparently can only gain adoption by obnoxious bullying.

It’s too late for Wayland, much like it’s too late for System D. The hyper childish bullshit chased me, and many others, away.

Tech Procurement and Why PayIt Deal Should Be Stopped at Toronto City Council
DTCC has higher requirements for concentrated positions than for other uncleared CNS positions. Couple this with Robinhood laying out its own capital to fund margin trades and Robinhood Instant trades, and you've got some pretty aggressive capital commitments.

(PROCEDURE XV)
288
II. if the absolute value of the largest non-index position in the portfolio
represents more than 30 percent of the value of the entire portfolio (the
“concentration threshold”), an amount determined by multiplying the gross
market value of such position by a percentage designated by the
Corporation, which percentage shall be not less than 10 percent. Such
percentage shall be determined by selecting the largest of the 1st and
99th percentiles of three-day returns of a composite set of equities, using
a look-back period of not less than 10 years that includes a one-year
stress period,2 and then rounding the result up to the nearest whole
percentage.
The concentration threshold would be no more than 30 percent, and would
be determined by the Corporation from time to time and calibrated based
on the portfolio’s backtesting results during a time period of not less than
the previous 12 months.

Also, the fact that the man running Robinhood gave out material nonpublic information on a a private podcast with a billionaire says a lot about his judgment, in my opinion.
Thank you for the candidness! I've found it interesting how the story of a startup's early days morph into legends / fables.
Google still growing revenue at 23% YoY?

Facebook, Apple, Amazon, Microsoft and Google. All of them beat even the most optimistic estimates.

Will have to dig into whether the cost of being Apple's default search engine has risen. Generally speaking it should $10 / user / year. Apple just reported another 200M increase in Active Devices. There should be some hint, or may be it will have to wait until next contract negotiation.
Something that always stuck with me is I remember reading in a book about the internet long ago about how innovative the name Amazon.com was and how it was the future of internet business. It said it needs to be more memorable. You aren’t going to buy your books on Books.com you are going to use Amazon. Turned out to be very right. And this was in the pets.com era. Everyone thought you needed the most generic name possible and that if you got something like books.com or travel.com you had cornered the market on it.
The Russians also were fond of “give it more gas”, which SpaceX has also embraced and Elon has called out before. The fuel is a real big piece of the launch cost but it’s far from the largest. If your rocket equation calls for a little extra fuel but in exchange you can use more reliable or at least less exotic parts, just do it.
Often you literally don't have hiring headcount allocated to your team. Sadly the solution is to make the team implode to force the company to fund it properly.
How is saying that some past act was wrong "rewriting history"?

Rewriting history would be saying that the past act never happened.

Andy Jassy to Replace Jeff Bezos as CEO of Amazon
Lol. You cannot judge your order execution quality as a retail customer. It takes the SEC years of investigation to do that. Its certainly not something retail brokers compete on.

Robinhood lied and should be punished but they were penalized for doing so before other brokers had gone to $0. It remains to be seen what happens at the other brokers now that they are free.
While Bluetooth may eventually drop backward compatibility, my daily driver headphones are four c.2007 Dell BH200 A2DP sets. Highly adequate. All are on their second battery, a commodity 500mAh LiPo from eBay. To hell with this overpriced Apple trash.

My first thought logging into their mobile app and desktop was "Jesus Christ this is terrible". Maybe it is functional, but RH knocks UI out of the park.
> So you can say on March 1st that you want the $1000 now.

So, you state that in the morning - every morning – assuming you won't have an income and then when you hit it big on GME stock at lunchtime, you pay it back at 5PM? Seems like a lot of work that won't happen in practice. It is not like you can know in advance if you will have income for the day or not.
> corporations are not democratic, and putting so much power in the hands of one person or a handful of people is dangerous to society.

Citation needed. Democracy is not a sufficient nor even necessary requirement for prosperity or "good" in general.
They are legally prohibited from using the customer's funds for the deposit requirements.
Could even see it breaking up at some point. Retail, Consumer Tech, and AWS. There's no real tie between AWS and the rest of Amazon at this point. In fact, it might be a liability as competitors of Amazon retail & Consumer tech don't want to use AWS.
The parent comment talked about the syscall, not the library

return((caddr_t)(long)__syscall((quad_t)SYS_mmap, addr, len, prot,

The first argument is the syscall number, the rest are
the seven arguments in question.

Clearly the pleasure of C is the feeling you get when your software fails spectacularly on unexpected inputs.
As an Australian engineer, I low key hope the same.

However, I'll be sticking with a VPN and google for technical related searches (Bing/DDG can't compete with Google, unfortunately).
They do have margin accounts, but as I understand it, that was not what caused these deposit requirements to shoot up. I.e. the margin accounts were not what caused the problem.
It's called a backplane.
I am not surprised they haven't made an API public yet. Looking at how razor-thin their operational margins have been on IT and financial fronts, any hypothetical added load from traders trying to algorithmically hammer some API is probably going to wind up in disaster.

I cannot speak for all of the engineering that goes down at Robinhood, but the way their web-based trading interface performed for me was regrettable at best. Never was able to load my history in that interface without my browser getting javascript timeout warnings. Always had to go back to my phone to see what dividends I got paid out. This sort of problem, which strongly-encouraged me to switch to a different broker, does not give me much confidence that other areas of engineering at Robinhood are handled much better.
Simply: does revenue exceed cost of running it?

The book I referred to answers the "but engineering team doesn't have revenue".

Engineering can be art, sure, and if you like, we can even discount the idea that art creation can be seen as economic activity. But is there a need to measure productivity then?
Would you care to elaborate? You're talking about the Y of the XY chromosomes?
I don't think the "responsibility" part is all that important. There are many points about it that can be argued, but I think the more important part is means.

Private companies' only effective means to do anything are to produce a product that people freely choose to buy and attract people to work for them (absent a few rare exceptions).

Governments have effectively unlimited means to compel people. They can spy on anyone, fine them, throw them in jail, kill them, all for as much and as long as they feel like.
I'll always remember Turnbull's laws of math come second to the laws of oz comment, heh. The last few of your prime ministers are much like Donald Trump. Science deniers that claim all sorts of nonsense. Crypto crusaders. Now this. How can a party have so many people like him and still win the elections? Aren't you fed up of having your country ran by these people?
To me - A type guard lets me be as picky as I'd like to be in the given circumstance.

I also use axios, and I also take advantage of the generics you've shown above, but I acknowledge that I'm essentially just saying "Trust me" and doing a cast when I do that.

And I'll add - that exact style of code has been a source of bugs in our production codebase before. A dev will pick the wrong type for the axios generic, and if the api response happens to overlap on the used fields, no one notices. Then it blows up 6 months later when someone tries to access a field on the defined type that wasn't actually returned in the api response.
Dante has no living paternal-line descendants. The reason for the unusual (for Italy) double last name Serego Alighieri was to preserve the Alighieri name despite there being only female descendants left at the time (in the 1500s).

To anyone who has a fond recollection of BlackBerry, I recommend the book "Losing the Signal: The Untold Story Behind the Extraordinary Rise and Spectacular Fall of Blackberry".

It's well paced and captures a lot of atmosphere (from what I recall).

And "Piloting Palm: The Inside Story of Palm, Handspring, and the Birth of the Billion-Dollar Handheld Industry" if you're into that kind of thing.
Sennheiser's HD 25 are pretty iconic for DJs, and they were initially released in 1988.

They're also known as being pretty easy to fix, because you can find a replacement for virtually every part of them, and they're sold brand new to this day. Plenty of people that own this specific model have had them for more than a decade.

Anyway, my parents didn't pass me down a pair of HD 25s, but my pair (whose initial release is older than I am) is definitely going to be usable for my kids. Whether they'll want to use them or not remains to be seen.
Watching it in slow motion, it looks almost like pieces of insulating foil.
Gotta hedge your bets, but I'm glad that I don't shop at diapers.com.
On the 'repeated failures' piece, that's somewhat new for aerospace. Traditionally, things would be over-engineered, and losing a test vessel would be considered a bad thing. SpaceX seems very content to blow up a bunch of rockets on their way towards not blowing up rockets.

This seems to have caused at least part of their recent issues with the FAA, who seem to be less ok with explosions. It will be very interesting to see if this iterative approach leads to more reliable rockets down the line!
Ugh. Any specific examples, just for the record, for someone who doesn't care enough to try the system?
Show HN: Hubstore – My contribution to how we distribute and manage FOSS apps
The deposit requirements were set exactly the way they’re always set.

RH’s main issue was that they had tons of customers with margin accounts, but they didn’t have enough cash to serve as collateral on that margin, when it was used to buy something risky.

It’s just a poorly capitalized, poorly run brokerage with shitty risk controls, but a very shiny and easy to use UI.

We already have (bad) ML-generated screenplays and (very short) deep fakes.

I'm willing to bet in 50 years, software will be able to fully generate new episodes of TV shows, incorporating reviews of the previous episodes. Maybe everyone watches the same generated storyline so they can share the experience and talk about it, or maybe each episode will be tailored to your specific tastes.

Point is that I doubt "running out of content" will ever be a serious concern for long-duration travel again.

Hi HN !

Months ago I showcased [1] Pyrustic [2], a framework and software suite to help develop, package, and publish Python desktop applications [3].

The framework adds megawidgets like Table and Scrollbox to Tkinter, implements views with lifecycle and more GUI related contributions. But it's not just a framework for the GUI, for example it comes with Gurl for resource fetching with a built-in responses caching system and support for conditional requests, multithreading made easier with even the possibility of retrieving from the main thread the values returned by the functions executed in other threads and also the exceptions raised by these functions, etc.

Pyrustic is not a framework highly specialized in a specific domain, but rather a framework which aims to help build full featured desktop applications (capable of resource fetching, database support, etc.)

Pyrustic is also a lightweight software suite: a command line program to help the developer manage his project, a graphical SQL editor, a graphical test runner, and also a tool to publish the packaged application on Github.

Once the developer has published packaged app on Github, the next challenge is: how to make the download-unpack-install-run-manage-apps process easier for the end user ?

So here I am back to showcase Hubstore [4].

I look forward to reading your comments [5], questions etc. Thanks for your feedback. Genuinely appreciated.

I think having one in Musk is enough (though Musk is married now). Don’t need planet of the billionaire bachelors in the midst of their midlife crises.
If you think profit motive, rather than ethics and benefit to society, should control prisons, the provisioning of healthcare, or the education of citizens, there is no middle for us to meet on.

> Social networking websites have become such an important source of information that even sex offenders should not be barred from social media, the Supreme Court ruled unanimously Monday.[0]

> other technologies can be leveraged

That’s my point: your software architecture must evolve to deliver on your promises (open-source Datadog) because it’s impossible to satisfy your promises with the architecture as it exists today.

Nonetheless, I appreciate all the responses. Good luck to OpsTrace!
Not really possible to give you a citation, it's an opinion, or a philosophy. If you have a different idea of an ideal society, we're not going to cite our way to an agreement.
> His lawyer had already turned up his nose at "Cadabra"

True. I've heard (employee #20k-something, joined in early 2008) that the issue with Cadabra was its resemblance to the sound of the word "cadaver".
Agreed. I think naming generic types makes the most sense with multiple types, or when more specific names make sense. For example, if a generic argument must inherit from a certain type: `class SomeView<ViewState extends BaseViewState>` or some such.

`Element` is as non-descriptive as `T` in the author’s example and, IMO, doesn’t add any tangible benefit.
I use Fidelity - the app sucks.

It may be 'excellent' relative to competitors in "shitty old financial company app" space, but it is in no way excellent compared to a high quality phone app.

Robinhood is successful because their software is actually good. My bullish case for them would be them leveraging this capability as a way in to becoming a Fidelity sized financial competitor.

Their CEO's inability to honestly communicate with the public is hurting them though. He should have lead with their liquidity clearing house issues and directly addressed the apparent conflict of interest. He appears to either be unwilling or incapable of doing this.

They've now after the fact explained some of the clearing house issues, but they still act as if they don't understand the conflict of interest question. Just address it directly.

When Elon asked him about it he should have said something like, "I can see why people would think we'd be under pressure from the funds that buy our order flow, but we live and die by our retail reputation and would not risk that to illegally coordinate with these funds. We'd go direct to our retail customers first. That said, we were not asked to do what we did or pressured by them, we had to make choices on the fly to stay liquid and in that craziness I failed to communicate what we were doing in real time to our users - that was my failure".

Instead he mostly dodged the substantive question and came across as full of shit (only addressing the narrow aspects not really in dispute). I think this could be the truth, but when paired with him lying on TV about their liquidity issues it leads me to distrust him, and by extension the company.

I suspect the reality is something in the middle, considering what RH's customers (the funds) would want, fear of mentioning their liquidity issue causing a run, and the clearing house concern. He handled this poorly.
Not if the protocol allows the exchange of desired DPI/scaling.
We also lost all three astronauts in a test of the Apollo capsule which doesn’t count as flight but I think we would agree still counts in the buckets of blood both programs have spent.

If you do more tests which kill more people before declaring the system good, you don’t get to not count those people like it’s a different color of money in some bureaucratic dystopia.

In industrial applications there are still plenty of systems built on good old ISA and PCI buses with the host on one card and a whole pile of IO of all kinds of plumage on others.
There are libraries that do type-safe schema validation (an article I found in a quick Google is linked below).

That you can do something so sophisticated is a testament to TypeScript's type system.

However, if you were writing JavaScript, I think it's (unfortunately) uncommon to have this kind of proactive validation. So, for people writing TypeScript as "JavaScript + types" (which is a perfectly fine way to use it), they would just use a type assertion, which is just writing down the assumption that the JavaScript programmer makes when consuming but not validating external data.
