>so that he buys their bread with that money.

So basically like any business out there reliant on incoming cash to pay suppliers?

This doesn't magically create money any more than the rest of the economy...which has believe it or not CIRCULATING money

Can you name one business that takes their supplier's money to buy back from them?

Not a big fan of the circular observation. It's not the gotcha people seem to think.

If the baker sells bread to the butcher, and the butcher sells meat to the baker then they can still both go to bed with a belly full of sandwich (aka actual utility & substance).

Adding a third party to make it look more circle-y doesn't change that logic.

Round trip financing is mostly an issue if it is artificial (e.g. a circle of loans) and between affiliated parties, not when something of substance is delivered. Oracle is a business partner of nvidia but I'd wager they'll still kick up a fuss if they don't get their pallets of GB200s. They'll expect actual delivery...like you know...in a real sale.

That's the wrong analogy, because the butcher is giving money to the baker for the bread. If we we fix the analogy, then the baker gives money to the butcher so that he buys their bread with that money. The butcher cannot afford the bread without it!

> dates back to the late 1890s and will be replaced with a modern, more durable, metal trough.

I think any infrastructure that has lasted over 130 years is already quite durable.

It's probably not the same wood since 1890. Requires more repairs and replacements.

Oh man being able to pick the time range is awesome. I hate hate hate standard financial data tables and how they just show you "today's performance". Absolutely useless, nobody in retail cares outside of gambling day traders. How is it that even giants like Fidelity can't get this right? I need to be able to see my portfolio's performance over the last month, year, 5 years!

This was submitted with a title that doesn’t match the page and is not even accurste (Please donate to keep Network Time Protocol up) is not correct. This donation page is not for the public NTP pool. It’s for the NTP Project organization and their web page.

All of the angry comments from people who think NTP will stop working if the donation bar doesn’t get to $1000 are misinformed. Also note that the bar isn’t updating. It’s been stuck at $365 for myself and others despite donations coming in.

I see it at $2,130 fifteen minutes after your comment.

Being associated with delivery vans would dilute the Tesla brand. Imagine seeing beat up Amazon vans with Porsche emblems - it wouldn’t improve your perception of a Porsche as a car you would love to one day own.

Yes, other things the company or CEO does are also diluting the brand. It’s still true that the company can be making a rational decision not to attack this segment.

Rivian’s marketing people probably hate that they’re doing this, but the company had $2.5B revenue and still lost $1.6B the first half of 2025. They’re in survival mode.

They're literally Mercedes today though.

There is a way to indicate whatever class attributes are defined, those are kwargs to the init function. For one, you can use `kw_only` on the dataclass decorator [1], alternatively you can use the `kw_only` arg on the field function [2].

That's only for dataclasses, you can't implement your own class like this without implementing it as a dataclass, because the typechecking for it is hacked in as a custom plugin.

What I'm trying to point out is that these features exist in core Python and yet the type system they built can't express it. By contrast, TypeScript is designed in such a way that you can implement everything yourself without having to write "custom typescript checker plugins".

Dataclasses support optional fields and kwargs perfectly. Not sure what you are talking about.

I don't think you understand what Pydantic brings to the table or why people use it. It has lots more to do with serialization, complex validation and data mapping.

phailhaus · 2 months ago

kwargs are not dataclasses, they are dicts. TypedDict was shoehorned in later to allow typing dicts, but they are so poorly designed that you can't mark individual fields as optional.

The type system’s alright. It just gets especially tricky when you’re trying to check code which won’t exist until you run it. For instance, suppose you wanted to load your own module from a database with something like

  foo = eval(result)

It can’t know what you’re going to load until it actually does it.

Things which lean heavily into metaprogramming, typically ORMs or things like Pydantic, fall into that category. I can’t hold that against the type system.

> I can’t hold that against the type system.

I think we should. Dataclasses have existed in Python for an extremely long time, and yet the type system doesn't support defining your own similar classes. Kwargs have also existed forever, but they forgot to support that and had to add TypedDict's much later. And it still doesn't properly support optional fields. There's a lot of stuff like this in the language which are unbelievably frustrating, because for some reason they implemented the syntax before implementing a typechecker. Everything has been hacked in ever since. I consider python's type system to be a lost cause, just hoping for someone to make the Typescript equivalent for Python.
