I just went through the DSGE wiki page [1]. It says the following about the model, which if true, then I can see why it is an completely unserious model.

> Below is an example of the set of assumptions a DSGE is built upon:

    > Perfect competition in all markets
    > All prices adjust instantaneously
    > Rational expectations
    > No asymmetric information
    > The competitive equilibrium is Pareto optimal
    > Firms are identical and price takers
    > Infinitely lived identical price-taking households
> to which the following frictions are added:

    > Distortionary taxes (Labour taxes) – to account for not lump-sum taxation
    > Habit persistence (the period utility function depends on a quasi-difference of consumption)
    > Adjustment costs on investments – to make investments less volatile
    > Labour adjustment costs – to account for costs firms face when changing the level of employment

Are these not the 'friction can be ignored' assumptions of economics? They are, of course, blatantly false. But that doesn't stop such models from effectively modelling real-world behavior.

Granted, I know a slight bit about general equilibrium theory, but nothing about DSGE.

I'm always surprised when people suggest using a different language if you want typing in Python. Python's (second?) largest appeal is probably its extensive ecosystem. Whenever people suggest just changing languages, I wonder if they work in isolation, without the need for certain packages or co-worker proficiency in that language.

I know I am going to be in the minority, but I don't understand why we can't let Python be Python. Static typing is great, and there are already other statically typed languages for all your needs. Why not use them?

Well, at least it doesn't create two incompatible Pythons like async and (I assume) free threading.

Because you can now use typing WITH the entire Python ecosystem.

It was nighttime in Singapore when the ruling was announced. My husband and I scrambled to find a flight back. The best we could find, at any price, lands 25mins after the deadline.

We are on our way there.

HN is usually negative, cynical, skeptical, eyerolling, regardless of topic.

Just the other day someone posted the ImageNet 2012 thread (https://news.ycombinator.com/item?id=4611830), which was basically the threshold moment that kickstarted deep learning for computer vision. Commenters claimed it doesn't prove anything, it's sensational, it's just one challenge with a few teams, etc. Then there is the famous comment when Dropbox was created that it could be replaced by a few shell scripts and an ftp server.

Thanks for linking that thread. Really puts things in perspective.

I disagree with this and what Dinnerbone says about locks. It doesn’t matter who file was intended for, it’s on the internet, if people want to use their silicon to do some mathematics to turn some numbers into some other numbers that’s their choice. It’s not equivalent to breaking into a house.

I personally don't see downloadability as a significant factor in the morality of breaching security. If it's bad to hack a login screen to gain access to private information, why wouldn't it be bad to hack encryption to do the same thing? What moral dimension does downloadability alter?

I think the house analogy fails because you cannot duplicate a house, take it somewhere else, and attempt to break into it there. If you could, that would undoubtedly be seen as a violation.

The usable amount of AI, no matter how optimistic you are about current progression, has to be below the projections the entire AI economy is living on right now.

Matthyze commented on The natural diamond industry is getting rocked. Thank the lab-grown variety   cbc.ca/news/business/lab-... · Posted by u/geox

My then-gf (now wife) and I watched a movie together about an African man whose village got raided, him put into slavery to search for diamonds and his son becoming a child soldier by the same people and their struggles to get free, and finally pawn off a pink diamond to one of the largest diamond companies in London. At the end of it, she finally came to realise that the diamond trade was really quite shitty. And we had a long discussion about the whole thing, as well as the growth of the synthetic diamonds industry and how they’re much better on the supposed 4C properties as well as on price.

Yet in the end she still wanted to get a ring from one of the big names because that’s what she grew up with and what she had always dreamt of since young.

¯\_(ツ)_/¯

The traditional finance system is that a single central bank, owned by a cartel of rich banks- chase, jpm, etc-- issue the currency, charge us to use it and get first dibs on the benefits of monetary inflation -- google "cantillon effect".

The now much more diverse mining space is much better than completely centralized in one entity current system.

And bitcoin community has a way of working to fix weaknesses wherever they find it... there is active campaigns to diversify mining, as you pointed out those are pools-- and pools are being made obsolete. behind those pools are thousands or tens of thousands of mining operators, of all sizes, as it's viable at industrial as well as individual scale-- many use it to heat their house for less than the alternative, the earnings don't have to cover the full cost to be beneficial to people.

Googling "Cantillon Effect" gives suprisingly few results. Out of the top five results, two are Bitcoin-related, one is Reddit, and one is the Wikipedia page of Richard Cantillon himself.

The top comment on /r/AskEconomics is:

"The cantillon effect doesn't really exist in any significant capacity. Central banks nowadays announce their actions well ahead of time, that means before the actual expansion of the money supply, people know this expansion will happen, and markets price in that expansion. So there really isn't much benefiting from being "early".

Beyond that there really isn't much empirical evidence on the cantillon effect to exist in any significant capacity."

Since I know little about this topic I'd appreciate HN's view.
