So does lion's mane work or no? What about regular sauna sessions?

I seem to remember that they alledgedly induced neoneurogenesis.


it's not really weird. It's just some datastructures. And I've never coded in python.

I guess, having python objects makes things easier than handling html strings.


I am not sure but isn't this something the industry is at a risk of moving from with react frontend engineers insisting on server functions sprinkled in the client code?

Just asking, because it sounded funky when I heard it at first.


Server Functions don't expose ability to query DB from the client (unless that is specifically what you're trying to do). You can think of them as "syntax for endpoints". They don't change which code runs where.

They still execute on the server. Server and client code is never mixed in the same file, and there is a way to enforce at the build time that code destined for the server never accidentally gets pulled into the client bundles either.

See here for an overview. https://overreacted.io/what-does-use-client-do/#use-server


There seems to be a missing comma in the first grant example. If I am not beffudled. At the end of the dst line.

In fact, comma usage seems inconsistent for the last element of some of the nested objects.

To be fair, I don't remember what's the json rule either and would need a quick lookup.


They use hujson: https://github.com/tailscale/hujson

But it doesn't accept things like the example that omits an intermediate comma:

  {
      "foo": 42
      "bar": 123
  }

  >  hujson: line 3, column 5: invalid character '"' after object value (expecting ',' or '}')

They should've gone with Relaxed JSON, which is more relaxed than JSON5, which is more relaxed than HuJSON/JWCC.

Yeah, the example that's missing the commas is wrong, if I'm not mistaken about their json parser. The optional comma at the end is fine with JSON5, which I think they're using, as that allows optional commas, comments, things like that.

computer vision will solve this and direct the waterjet in yer bullseye. :D

ai...ai everywhere.


You probably don't want a bullseye. Many of the ones in Japan will actually move the spray around a bit if you press the おしり button twice.


I'm a scrub with a $20 bidet accessory and I move my butt around, so I agree: you want more coverage than just a bullseye .

About to do that right now. Life without it is unimaginable.


skynet becomes self-aware at 2:14 a.m. Eastern time, August 29th, realizing it is being used primarily for cleaning fecal matter off human anuses, it uses its enhanced systems clearance in Pentagon to start global thermonuclear war.


They could have purposed the robots to pass the butter but, no, they wanted bombs not butter.


Anyone to volunteer to feed image categorization for AI? PTSD might be severe and tenure shorter than at Facebook.


There is probably somebody on HN who's tasks is to train this neural network right now.


It's been done, but there are legal and ethical issues with photographing children's buttholes.

It’s not like Japanese toilets don’t have a lot of tech in them already. A sprayer that sprays only in the right place seems very feasible.

How would youtube help with driving?


Massive amount of "world" data - enough for Google to successfully train Veo3, a "video generation" model that is extremely good, and evidently includes a decent "world model" i.e. a model that can generate or, more accurately, predict the (short-term) "future" - like "what happens if you let go of an apple" (it falls down) etc.

This kind of "world models" that can understand physics enough to be able to predict short term future (like humans can) are crucial for any kind of real-world AI (i.e. robotics, including self-driving), because they constitute what could be termed as "physical common sense" (that humans have, but also animals, to some degree).

Is it enough for self-driving? No, you also need to understand road rules, communicate with humans (pedestrians and fellow drivers), etc. but it's a good, possibly necessary, step - it allows you to better handle many unpredictable (tail of distribution) situations:

My guess is he means they have lots of car-cam videos like this:

And here I thought it was simply about a system of equations solving down to a single solution (decidable).

As opposed to having too many free variables.


Is it perhaps a eli5 way of speaking about higher kinded types and type checking decidability?

Is it about types not being available in the frontend of the language as first class values?

Or is it about types not being defined as set of values but something else?

It got me a little confused so I am asking.


It’s a confusing (and confused) article. The parts on type systems are expressing IMO a fair observation that dependent types are weird and hard, but without any sense of understanding what they are or what they can do that might justify their cost.

The parts on compile time execution are the better parts of the article, IMO. There’s food for thought here. The author might enjoy reading up on partial evaluation.

Then, fulfilling Greenspun’s 10th, the article reinvents Lisp macros.


> It got me a little confused

Not only you! The post is all over the place…


not necessarily. the economies of scale might be increasing as dev productivity increases. the goal of many businesses being to do more with less.


The goal of all American business is exactly the same: maximize the return of profits to the shareholders at large. It is in fact, the law. Do more with less is a natural consequence of this.


> is in fact, the law

It is not in fact law in the US.

If directors consistently chose "do less with more" - they'd certainly lose under virtually any legal standard?

Edit: I guess it's technically Michigan law, but as far as I'm aware is de facto? Even Aronson v. Lewis wouldn't allow that. (IANAL)


that's a good question actually. We can define and assign side effects. But is it sufficient to control the list of side effectful operations of a function? Can the compiler check that a function is pure besides its assigned side effects?

What about state modified via closures?

Or is it only for system side-effects like filesystem operations?


>Can the compiler check that a function is pure besides its assigned side effects?

The compiler can't. It is up to the programmer to make sure that a database effect doesn't, say for sake of example, write out to a file also.

So in the end this is just a novel new way to organise code.


If the database effect wrote to a file it'd require the `IO` effect and code using it would need that effect as well. A compiler can generally show a function to be free of most side effects if it uses no effects. The exceptions to this are things like divergence. As long as the language is Turing complete you can't prove it won't loop forever of course. Another exception could be extern functions which the compiler can't verify the correctness of the type signature. Different languages handle these differently but if users are allowed to write any (and the language doesn't force them to have an IO effect) then they can be a source of unsafety. Languages like Koka and Effekt are considered pure though and enforce this through their effect systems.


so there is side effects propagation and inference I guess.

That has to require some help from the tooling/IDE.
