I have a feeling that it might be due to C++ solution not being proper BFS since it doesn't have anything preventing the visiting of same state multiple times. One thing that slightly tripped me is that full BFS state space without additional tricks is in theory N^2 (current length x copied length) . Also the memory usage for C++ solution is ~1.8GB and bumping N to 200K increased it to 6GB . I assume that Picat automatically detects and prevents duplicate computation on identical states.

Got nerd sniped. If you think about the problem a bit harder (but not hard to go into math of prime factors) there is a dynamic programming solution. The code for obtaining only steps is a bit simpler, but it can be also extended to recover full answer https://gist.github.com/karliss/5ca978390791daca71a1d812c43a...

Had no issue obtaining full 9104 step solution for ==100001 .

On my computer:

C++ DP: <0.003s

C++ from article: 3.032s

Memory usage of DP solution is linear. The double nested loops look a bit scary, but it actually forms harmonic series sum: `sum (n/i) ~ n log n` so the speed isn't bad for non analytic solution.

The main insight for fast DP solution is how to reduce the state space from NxN (lenght X copied length) to N. All solutions will be in form (SC(P)+)+. Once you know minimum step count for reaching some length, you don't care about what the currently copied length is. Assuming you reach some length L_2 = L_1 * i, any solutions L_1(i+j) would already be processed when handling L_1, means you only need to updated L_2 (i).

Now that I have written it I get where the factorization related math talk in stack exchange comes from.

This is a nice example to do inheritance the Rust-way using composition instead of OO, but still I'm missing some essential parts for which I have not found the proper Rust idioms yet.

For example, when building a widget hierarchy, I would like to be able to pass widgets of different types to a function or store them in a `Vec<>`, but this is not possible since these are different concrete types.

Trait objects can help here, but then Rust lacks the machinery to upcast and downcast between types as there is no RTTI attached to these trait objects; you can not cast/convert a `Button` to a `BaseWidget`, or a `BaseWidget` that was originally a `Button` back to a `Button`.

What would be the rusty way to handle this?
Of course I don't have a tally on how much things it has improved vs not improved but there are many things I can think of which are considered good but also resulted in bad: (social media providing connection while causing depression, cars providing freedom of movement vs pollution etc.) so its probably not something that can be truly decided one way or the other.

True fusion power? Rather than based on fusion steam power? As in, can collect and utilize the gama release? (Of which we are hundreds if not a thousand years away from.)

Floating cities, space ships that can travel at 80% the speed of light, and of course, whatever you need to run the most intense computational requirements, continually.

You may balk at "floating cities" (and I do mean actually flying cities that float in the clouds), yet once matter can be efficiently accelerated toward the speed of light, using such accelerated matter as a superior form of propulsion is right around the corner.

For comparison, one gallon of rich hydrogen (deuterium or tritium) contains the energy potential of ONE THOUSAND gallons of oil. That's by fusion not by burning which your quick search may turn up
They're actually formulated differently, at least at the Coca-Cola size of producer. It's worse for smaller, regional producers who use a single formula.
Soft drinks can eat away at container materials, and so part of the container becomes of the beverage. Glass is the closest to impervious, aside from the cap, so it's usually the same as the fountain formula, while Aluminum requires a plastic coating in the can, and the plastics used in plastic bottles are by far the worst. Large producers actually adjust the formula to minimize the taste difference, but it's only partially effective.
This same phenomenon also occurs in most beverages, including beer, juice, and milk, but the container varieties are far fewer across other beverages so most people don't notice. Milk out of a glass bottle is definitely better than milk out of a plastic bottle, for instance.
Soft drinks are not nearly as problematic in their concentrated syrup form, as it turns out water is a huge contributor to the problem, so they're usually just shipped in mylar bags.
As an interesting aside: Coca-cola products out of newer McDonald's automatic fountains dynamically adjust the syrup/water mix based on the amount of ice the customer asked for, so that when it melts during normal drinking it will be as close as possible to the ideal mixture.

It doesnt take forever to build. Its the fastest way to scale clean energy.

If Germany in 2000 had invested in nuclear they could be basically done by now and for far less money, even with incredibly conservative assumsions.

Just look at the build rate UAE and South Korea were able to achieve. Apply that to Germany, even without any effects from scale, and the numbers look fantastic.

And its very unlikely that you are gone have Fukishima and even if you do, most of that money isnt actually needed.

Nuclear isnt getting built much compared to solar/wind in what world do you live? Its the exact opposite.

Is it a "Mr. Fusion" sort of device you can use to power your car or home?

Or does it require a gigantic 10 sq km facility to reach that efficiency, but where the result can power Germany?

In the beginning 'twas the command line, and cmd was good, and it sufficed, for *computing* was the product. And we looked around and saw the IBM PC and Mac - and Amigas and STs and Commodores before them, and Spectra, and Lisas and IIe, all after their kind, and all was well - for they were computers.-

Then *the OS* became the product. And it needed glitz, and it needed a GUI. And so a GUI came. And then "updates" came - for we were now "online".-

And thus the "network" came, and we were "as one", and our compute was joined forevermore, and we could no more tell our children from our children's children and our old age from our youth. And sadness and pointlessness was turned "social" into glitz. And everything from our infirmity to praise went there as plain as day and dark as night for all to see. And all seemed well.-

And it came to pass that our user accounts went on the net, for they were "subscribed", and they were also "online", for they had lost their flavour. And the advertising came ...

Now, we ourselves are the product. The "network" is the computer, and much woe is to come. And there shall be much girding of our loins, off of our loins as well, for our hardrives and compute are places of consumption, rented out under pretense of service to those that run the bits.-

For now AI is also come, for we have ourselves trained it, with the fruit of our sweat and our tears. And all is well and will be well, for AI shall be unto us a confort in loneliness, and a hand in our fields and unto us an oracle for all truth and wisdom and even law - with time.-

And we forgot our code and became garrulous and forgetful of our trades and machinery, and we knew less and less with every season. And it became the law to know the code no longer, and the trades. For it was now a crime and deed of evil to gaze upon the code, or long for it, or learn, or have our trades as did our fathers.-

And the computer shall no more exist, for all will be compute.-

Not really.

Let's use the UNCTAD definition of developing countries - there are a number of countries which exceed Canada's per-capita energy usage (the highest of those I mention above) - Qatar, UAE, Trinidad and Tobago and Kuwait.

But those are all small countries, the highest per-capita energy usage by a larger nation is Turkmenistan (exceeding all of the European countries mentioned in the parent - UK, France, Germany - and Japan).

But that's not really the point. Doubtless there is a correlation between energy usage and standard of living. But it's not a 1:1, and there are some huge benefits to be gained - e.g. the US (77,028 kWh / person / year) has triple the usage per capital of the UK (28,501 kWh / person / year). Even in Europe, France and Germany could reduce their usage by a quarter to bring it to the UK level.
Those are lovely. Some of them remind me of the mount on the Edmund Scientific Astroscan telescope. But have they made a doll-scale version?

Except this isn't really true. Humans throughout history are invariably tribal, not solitary. Their solitary pursuits are in many ways profoundly modern and in keeping with the entire tradition of solipsistic modernity.

But...so? The same could be said if they moved to any developing country (I live in a developing country) but nobody is valorising that in the same way.

It was a very dumb choice to push this anywhere.

maybe that's really where the business here is.. working through a whole bunch of custom data-sets and trying to generalise from there. It'll be hard to generalise all of it, but I'm sure there'll be pockets of functionality that can be shared across more than a single data-set.

And maybe that's at the core of the issue here, namely that this service in its current form doesn't scale like b2c internet tech

But this is a category that didn't exist yet. So who knows what people without art skills or budgets might do? Probably nothing, but maybe one in ten thousand actually isn't garbage. Just like music at the advent of digital home recording. The market is already so flooded it hardly matters.

I'm an artist and a gentleman coder and I'm disgusted and offended by careless work. But I don't think I need to die on the hill of stopping infinite crappy game mills from having access to infinite crappy art.

I'm also just bitter after years working on pretty great original art / mechanics driven casual games that only garnered tiny devoted fan bases, and so I assume that when it comes to the kinds of long tail copycat games you're talking about, especially with AI art, no one's going to bother playing them anyway.

I agree. The complexity doesn’t lie in the abstractions that these frameworks are selling.
I think you're oversimplifying the issue. It's not important that the model cannot distinguish between people of different demographics, it's important that the model does not use demographic information in place of actual diagnosis for the sake of better accuracy.

That the model can determine biological sex from X-rays wouldn't be an issue if it never shortcuts the diagnostic process by using biological sex in place of meaningful diagnostic data. I would not like a model to ignore a melanoma in my chest scan because it can deduce that I was born male and my risk of breast cancer is quite low.

The idea of penalising a model which takes such biological shortcuts (because its subgroup accuracy gets worse) seems like a good solution, and it's cool that the approach works in TFA.

To be fair, 128 are maybe $2.5 million revenue for AMD. If they predict $4b then we talk about 200-400k MI300X. For every $1b more revenue, AMD needs capacity from TSMC in the area of 50-100k. To be frank, your 128 are a rounding error in that.

I’m consistently impressed on how well Supermaven works. I’m using it for my hobby/side-project and it feels like a superpower when I want to refactor something that needs knowledge from other parts of the code base and as soon as I write a couple characters almost immediately it does the rest for me. It pulls the tedious parts out of coding and lets me focus on stuff that really matters.

Of course it’s not bulletproof but over time I’ve learned what its limits are and when I can’t rely on it. I’m excited to see how this release improves things.

City size is all definitional.

My first ever look at the states was out the window of a plane flying to NYC from the Bahamas at night. Straight up the east coast. Mind blowing. To my eyes it was one enormous city without any meaningful separation all the way. I was expecting to be surprised by the scale of the usa and yet it was way beyond what i could imagine.

Others won’t share that definition.

I don't even see the need for leap seconds at all (in either direction). Why should anyone care? All times are relative to some arbitrary fixed point in time anyway, so why are we so hung up on maintaining the status quo?

Aside from the fact that just by ignoring the problem it'll probably go away - we've just had a period of adding a load of leap seconds to roughly compensating for the Earth rotating "too slowly" overall, which for a system that's inherently irregular and actually speeds up and slows down all the time, and just happens to have been "too slowly" ON AVERAGE. It now seems hat the rotation speed, on average, is "too fast" and now we need to undo some of that adjustment. If we'd just left it alone, it'd have been fine.

And for all the hassle these leap seconds cause, what exactly has been the benefit? Since 1972, we've had 27 seconds added. 27 WHOLE SECONDS. That would have made absolutely no difference to anybody's life if the sunrise and sunset was 27 seconds later.

Just think, in 100 years, when your great grandchildren are enjoying their life, we might be a whole minute wrong. And if you went the other direction, back as far as all of recorded human history, and we might be out by an hour. Many of us are routinely forced to have our clocks out by an hour for "daylight savings time" every year anyway.

For the very few cases where it might be useful to know the ACTUAL difference between the rotation and alignment of an abritrary fixed point on earth and an arbitrary fixed point on the sub, then THEY can use they own clock for that specialised purpose. And maintain a fixed adjustment to the atomic clock based time that everyone else uses, and they don't even have to round to a whole second for that - they can say NASA time is TAI+1.234s for instance and the only people who need know or care is NASA themselves.
