You are using very combative and insulting language, which is not helping.

> This smart watch is being advertised for actual kids. 6-12 year olds. Do you actually think a 30 year old is going to keep using their toy watch for 20 years, stay on their parents phone plans and their parents are going to track their 30 year old child?

No. I was not discussing the watch. I made a comment specifically on your statement about whether a parent, which initially has used location tracking on a child, will keep doing so as the child has reached the age of 30. And my position is that yes, very many parents will do so if they don’t need to alter their habits significantly in order to keep doing it.
> the bus is a strictly worse version of the car in these kinds of cities

You can change that by giving them their own lane so they don't get stuck in traffic with the cars, let them go where cars may not go, give priority at traffic lights etc. That is what they do where I live.
It did not widen the highway.
To expand on that, with small and midsized cities, daily cost of transit rides vs. gas is on parity. Of course this does not include maintenance, insurance, and depreciation, of owning and driving a vehicle, but most people only encounter those twice a year, vs gas and bus fees are daily and weekly.

In small and midsized cities, driving a car takes less time, likely 1/2 to 1/3rd the time of taking a bus.

Lastly, there’s the sense of control over personal space. When you’re on a bus, you do not control who gets on the bus with you. When you’re in a car, you have total control.
Anytime you want. You just have to live modestly.

I’ve only done htmx and html + jQuery (&JS) interfaces for web but both were very reactive and hard to tell from native. What gets you is data fetches over networks. Can seem native when local and glacial over a slow network connection. I don’t think it’s necessarily the react/htmx/ etc frameworks, it’s the architecture usually. Javascript + DOM can be really fast, at least on modern hardware.
It all depends on how you define "efficiency". For the grocery example, getting food items Just-in-Time would result in fresher food, less wastage and more flexibility.
Let's say your colours are black, white, green and purple. So far, you've managed to use only black and white, but you've reached a node with both black and white neighbours. You need (are forced) to choose a different colour! You could choose green, or purple ­– and whatever solutions you reach from that point, you could swap all the greens and all the purples to yield another solution. However, the next "free" choice you make could be the same colour as you chose last time, or a different one, so it is actually free (so isn't forced).

Since the "swap green and purple" operation is bijective (a one-to-one, reversible mapping), and preserves all the properties we care about, we can call it an isomorphism. If there's an isomorphism between two solutions, we say that those solutions are isomorphic. Swapping all the greens and purples of any isolated region of the graph (i.e., one surrounded by a strip of black and white) is an isomorphism, if the only property we care about is "is this a colouring of the original graph?".

I was saying it's pointless to search isomorphic solutions if you can help it. If you have isolated regions of the graph yet to be filled, you can halve the time it takes to explore each region's possible colourings.

However, if you consider isolated regions completely separately, you can solve them one after the other (and backtrack once you know any region's been made impossible by the choices of colours in its border), for a much larger speedup.

The whole thing about isomorphisms was a red herring, an artefact of my thought process rather than an actual insight. I doubt trying to exploit this will net you anything more than a 2× improvement, and that's only if you do it cleverly.
"Induced demand" is a fallacy that planners love because it lets them do what they want.

Demand isn't created. It becomes visible when it looks like it might be satisfied, but that's a very different thing.

The article said:

Researchers then administered D-βHb, a form of ketones, a byproduct released by the liver when the body burns fat instead of glucose for energy. They found that the synaptic activity that was previously impacted by acute insulin resistance was rescued,

looking further, D-βHb seems to be an exogenous ketone:

Exogenous ketones are a class of ketone bodies that are ingested using nutritional supplements or foods.

...

Under physiological conditions, ketone concentrations can increase due to starvation, ketogenic diets, or prolonged exercise, leading to ketosis.[2] However, with the introduction of exogenous ketone supplements, it is possible to provide a user with an instant supply of ketones even if the body is not within a state of ketosis before ingestion.[1] However, drinking exogenous ketones will not trigger fat burning like a ketogenic diet.

...

When exogenous ketone bodies are ingested, acute and nutritional exogenous ketosis is produced.[4][9]

so, how do we supplement our diet?
This is a really great reply. I wonder if that's a direction I should look into - helping people sort information, and find what really matters.

Hi everyone,

I recently conducted a test to compare the performance of 12 different AI models. Using a custom-made 65-question exam, I evaluated each model's accuracy and compiled the results. I thought it would be interesting to share the findings here and get your thoughts on them.

I was really surprised by some of these results. All the models did quite well, considering the questions were pretty challenging. Even the lowest scores were still at 87.69%. It was fascinating to see open-source models being very competitive with the best models available.

I bought the lifetime deal on chatarena.ai to have an interface to quickly test all of them.

Also, I tested Perplexity Pro, but it performed so poorly that I didn't include it. Maybe the 65-question test was too long for it? Usually, it gives me pretty good results, so I'm not sure what happened there.

In terms of general personal use outside this test, currently, GPT-4, GPT-4o, and Gemini 1.5 are my favorites. I'm still not sure which is better between GPT-4 and GPT-4o as the outputs tend to be quite similar. I used to be really disappointed with Gemini, but I think they've improved it a lot recently. On the other hand, I'm more disappointed with Claude, especially Opus. Yes, it did rank 2nd here, but it constantly messes up in my personal use where GPT and Gemini never do. I let my friends use my subscriptions sometimes, and they agree that GPT and Gemini have been outperforming Opus.

Please share your insights and thoughts on these results!

Fusion Chef for GitHub Projects
The Automated Project Integration Tool that seamlessly merges functionalities from multiple GitHub repositories into a single, cohesive project. By analyzing the input repositories, the tool generates a new repository with an organized file structure and instructions.

Example: You have one github repo for audio to text generation and one completely unrelated repo for text to image generation.
A tool where you point it to these two repos and it builds a third repo with all file structure, readme, requirements and also give you detailed steps like:
Add your api key in this file, add your output path in this file etc.

What are your initial thoughts?
Thank you for your reply! It is hard to uphold a conversation on HN over a longer time, so I appreciate your reply very much.
It's just Jevon's paradox. High prices suppress demand because possible use cases are infeasible/unprofitable, but lower costs make them possible until you have total oversaturation (but e.g. subsidized US corn results in it used in all products!)
It will change the habits of some but it’s not enough. We should continue to build out bus infrastructure and enhance bus rapid transit especially in the ways you mention, but those efforts won’t result in the large change we need to shift away from vehicle-based infrastructure.
At first I thought cnbc literally just wrote a headline as an article, and left it at that. Took me a while to realize it was a video link.
RAGs do not prevent hallucinations nor does it guarantee that the quality of your output is contingent solely on the quality of your input. Using LLMs for legal use cases for example has shown it to be poor for anything other than initial research as it is accurate at best 65%:

https://dho.stanford.edu/wp-content/uploads/Legal_RAG_Halluc...

So would strongly disagree that LLMs have become “good enough” for real-world applications" based on what was promised.

> Inducing demand can often be good.

I would quibble here, it depends. Another example I am thinking of is toilet paper during the pandemic when it was in short supply. At that time, when we were counting squares of toilet paper and predicting when you were going to run out, people used their toilet paper very efficiently. When it is plentiful, suddenly you don't care about using every last bit as efficiently as possible.

In my previous example in the parent post, everyone is still making it to the grocery store and/or work, but it's a question of how efficient people are incentivized to be when making those trips.

When it comes to highways, I'm guessing that it's more the case that inefficient/unnecessary trips become more economical than typically enabling people to make a given trip at all. I know a lot of people are pretty lazy about planning their trips, I'm guessing there are a lot more of those people than those that cannot go to a city because it requires 45 minutes instead of 30. Just my guess there though, and certainly that is context dependent.

I like your points regarding efficiency of cost for expansion as well. Though, my point is more that induced demand is the minimum efficiency of a resource someone is willing to incur for it to be worth the cost of using that resource. That latter part, is a bit independent of the cost of building that resource in the first place, though that construction cost is still an important thing to consider.

Yeah this is an interesting point. Other threads make the point about the "bitter lesson", and how expert-trained ML has historically not scaled, and human-generated LLM training data may just be repeating that dead end. Maybe so.

Something that is new this time around, AFAIK, is that we haven’t previously had general ML systems that businesses and consumers are paying billions of dollars a year to use. So if, say, 10% of revenue goes back in to making better data sets every year, I can imagine continued improvement on certain economically valuable use cases – though likely with diminishing returns.
A friend built a system where the ad campaigns with all their targeting rules were Lua scripts and it was also fast and simple in a glorious way!
If they published it freely then they wouldn't get paid. I thought everyone was mad about how there aren't enough employment opportunities for PhDs? Training LLMs on your area of expertise is surely preferable to working a dull office job that has nothing to do with what you studied.
I think we all know this, but have different definitions of "fast enough".
You don't need to. Every social media implements this and has done so for years.

You can trust tradition, your instincts, logic, or science, whatever.

If you are stuck on constant skepticism questioning even the most blatant truths you will be stuck on step 1.
I consider it so forward thinking as to be unrealistic.

I hear what you are saying but my town is more or less in accessible and a suburb to know where. We don't uber and taxi's after dark should be considered ahead of time. We have minimal mass transit system that essentially connects towns together. If we ever get train service from a metropolitan city I could see it.

Currently I see the people demanding reduced parking requirements as echoing talking points they don't understand.
Yes, but I want to avoid FAANG services
why not free previous smaller chunk after reader finished reading from it?

for me it would be better to allocate new buffer but allow reading from old one until it contains data and after that dealocate it and keep only new one in use
The Amiga booted into the Workbench GUI. It didn't have a native "repl" as such, although you could open a window for a Rexx script interpreter. And if you booted from a floppy drive, that wasn't fast at all.

I occasionally click a button only to change my mind mid-click. So I can move the mouse pointer off it and then let go of the button, in effect avoiding the operation. This ability to back out is a good for command-like events. Changing tabs not so much perhaps but probably traditionally done for consistency.

X window was the odd one out in the old days that would show a context menu on mouse down. Made it feel a bit unrefined.
I’ve done this with a new and thus terribly sharp knife. I’d bought it for my mate, so when I knocked it off the bench my reaction was oh no! damage! catch!

The kitchen looked like a scene from Kill Bill. Perfect blood spray in an arc across the wall.

This mate lived with me at the time. And he was a nurse. He came home from his shift about half an hour later and I told him, sorry man, but you’re driving me straight back to the hospital.

I’m lucky to still have total use of my right middle finger.
I tried this in the past, I absolutely could not last past 36 hours, all I could think about was food. The easier way for me was to do the Atkins fat fast, which basically 800 calories of 90% fat for a few days to kick myself into ketosis. I’m not sure why I needed with a capital “N” to have food when I tried a “hard” fast. It could be a mental block, as a child I was never allowed to skip a meal, even if I only ate a little bit. Weight didn’t become an issue until post 30 :)
I was laid off with zero severance and no recommendation etc from a company that was big on "we are a family".

Never heard from one single person there after the layoff. I was like yup this is how my family is too.

Ever since I have always felt joining a company is like getting adopted into another dysfunctional family.

Seems like it should be easy enough to offset with exercise though? Like if you’re doing cardio a few days a week you’re not going to suffer too much by chilling in bed a couple evenings.
How did you discover the dangling transaction?
I’m getting the sense you’re not really familiar with the accounting terms you’re using.

Opex hits the income statement. Capex does not, because it stays on the balance sheet. It is free money in that sense. And that’s generally good because we WANT the utilities to BUILD ASSETS. They wouldn’t do that unless the incentives were there. It is definitely not the case that opex is broadly a good thing or climate oriented thing. Building solar capacity is capex too.

The expenses are not a free pass either way. Utilities must justify the expenses to build them into the rate case (prices they can charge). Lots of stuff is just on them without being built in too.

There’s certainly problems and difficulties with this system but it’s not terrible. You don’t want multiple companies building the same infrastructure in the same place. That’s just hugely
Inefficient. You don’t want a free market monopoly either.

All it takes to drive specific incentives is to have the regulators demand specific goals to approve the rate case

By the same hand on the employer side. If the doctor employee is good then you want to keep them if they are the only good doctor in town. Even if they're not great if they are consistent you want to reward them because the replacement would have to be convincing someone out of town to move. But if you live in a large city with tens or hundreds of possible doctors you know your doctors will likely be poached but there are also more where they came from so why bother rewarding loyalty when you don't need to be loyal to your employees?
There's a number of reasons for this. The first is that the quant physics community has never really adopted functional programming. It's not particularly obvious to scientists, who typically want to express their computation the way they want to- something that C, C++, and Fortran are all long-established at doing. The second is that much of physics depends on old libraries written over the last 30-40 years, and it's easiest to use them from a language that the library is written in, or one that has a highly similar interface (for example, Python is similar enough to C++ that many foreign function interfaces are literally just direct wrappers). The third is that types (other than simple scalars, arrays, and trees/graphs) have never been a high priority in quant physics. The fourth is that undergrad education outside CS rarely teaches students Haskell, while most undergrads in a quant field graduate knowing some amount of Python.

It's much more likely the physics community would adopt Julia, or maybe Rust, and even that has been pretty slow.

(nothing I said above should be construed as taking a position about the suitability of any specific language or lack thereof for doing scientific computing. I have opinions, but I am attempting to explain the reason factually with a minimum of bias)
Unfortunately this is neither true for the island of Sylt and it's not true for the city of Berlin, either. Locals do get priced out, apart from the lucky few who—most of the time—own property that they can either survive in or profit from (your own apartment w/o rent hikes and/or your 2nd apartment that you do hike the rent of). The workforce is mostly sourced from younger, cheaper, more mobile folks who can better put up with more work, more shared living spaces that are further away or more expensive and so on. When owners get old and property prices are constantly rising they will likely sell at some point to start over somewhere else or retire, and when that happens, it's as a matter of course, more or less over for the local folks because then the egregious property price as to be amortized by driving up rents no matter what.

After WW2 the population of Sylt was predominantly 'indigenous' (families who've been living there forever). Today, almost nobody who was born on the island still lives there, and nobody who lives there (for a few weeks per year) as any relation to the island (except using it to hang out every now and then). In Berlin it's not quite that bad but the satirical person in me wants to add, in an optimistic fashion, "we're getting there!"
There was nothing instantly about Amiga. It only has bootloader in rom. Booting to Workbench is a good 30-60 seconds from floppy, and its not much faster with a HDD (kickstart has some weird hardcoded wait loops). Loading new drawers (folders) is still slow (drawing icon at a time) on fastest accelerators (Vampire) and SSD.
