No bus route should be more than 15 minutes between full and empty. That is you start at some station, go 15 minutes, then turn around and go back. There are many systems that attempt to do more, but there is no point: people have places to be: on the bus is not on that list. That 15 minutes means an average of 7 minutes, now they walk to some other express bus that gets them nonstop (at faster speeds) to someplace, but you still only get 15 minutes to get there before it isn't worth the bother, than 7 more minutes on some other bus. Add in 5 more minutes of walking time (and transfer time!) and we are at 45 minutes - this is unreasonably long for normal trips already, but it is the best you can do!.

In short there are plenty of places to switch buses if you need to.
That goes for anything hydrogen and wheels pretty much.

It's actually pretty simple to figure out. Making hydrogen takes energy. You lose some of the energy making the hydrogen. This is not a fixable problem. At least not unless you break the laws of thermodynamics.

When you have created hydrogen, you lose more energy compressing the energy. Then you have to transport it to wherever it's going to be pumped into the vehicle ... both of which take more energy. Then it goes into a fuel cell, which loses more energy. All these losses multiply. And if you know your maths, you know that multiplying numbers smaller than 1 means the result gets smaller and smaller. These losses are significant.

And we're comparing it with putting the energy into a battery directly. It has inherently better round trip energy. Even if hydrolyzers, and the infrastructure to store, compress, and transport hydrogen were free (which they are not), using hydrogen would still be more expensive than that. Because it wastes more of the energy that goes in. So, in addition to the energy losses, you also need to deal with infrastructure cost. On top of regular energy infrastructure.

Anyway, that's all theory. For practice, just look at market price of hydrogen. Most of that stuff is of the dirty grey hydrogen variety creating that wastes a lot of methane. So much, that it would be cleaner to just use the hydrogen in a combustion engine in the bus and you'd have less CO2 emissions. Expending more methane to make hydrogen to have less emissions makes no logical sense.

If you are using grey hydrogen, it is more expensive per mile than methane. Nothing can change that. If you are using green hydrogen, it is more expensive per mile than battery electric. Nothing can change that either. That's just physics and simple economics. Yes there are some innovations in this space happening that reduce the gap a little. But it's never going to be enough.

Right now it's not even close. Unless somebody is subsidizing the hydrogen fuel, you'd be paying way more per mile than with diesel. And not just a little bit. And a common reason to switch from diesel to BEV is that it actually costs way less per mile than diesel. So, instead of saving money, you are spending more money.

Subsidies are hiding the true cost of hydrogen. That's the only reason there are some vehicles on the road. As soon as the subsidies dry up, hydrogen transport use cases evaporate. There are of course plenty of other use cases where hydrogen is needed that make much more economical sense. Using scarce and expensive hydrogen for transport is a poor use of resources. The utopian world where we have vast amounts of hydrogen surpluses does not exist.
Why do people keep thinking this thing is top heavy just because its taller than wide?

The heavy bits are at the bottom.
Yes of course. The impact of caloric restriction on metabolism however is FAR overstated as we know from the available literature.
"Starvation mode" is largely relegated to pseudo science at this point and most of the reduction in metabolism you speak of is due weight loss itself and a small reduction in NEAT.

But yes the human body is a complicated system effected by hormones, and other individual factors.

However it is important for the layman to understand the basics. It VERY rarely helps people struggling with weight loss to gloss over the basics and talk about metabolic adaption or provide other "excuses" like PCOS, hormones or starvation mode. They miss the forest for the trees.

The real answer is because this is a ton of work for very little customer benefit and creates tons of headaches to solve a mostly theoretical problem. It's not worth it to anyone involved.

> 2. A failsafe firmware reset back to factory state.

Do you mean like a physical button? That could work, though I'm not sure I've ever seen it. Holding down power for 10 seconds (or whatever) usually just erases user data, but doesn't reset firmware. Are you aware of any device that does this? But does it require some meta-firmware to roll back the firmware? What if that meta-firmware has a security flaw and needs to be updated? And that update is faulty?

If you're talking about a code sent from your servers to devices to reset, that seems like asking for the impossible. If a firmware update bricks the device, that may very well brick its ability to receive codes at all.

In both situations, it starts to feel like a problem of infinite regress...
What exactly are you suggesting?

Japan is a monoculture and strictly traditional, not to mention very xenophobic. Everything works because the social penalties for violating those norms are severe. It’s effectively an ethnostate and not that long ago revered their god-emperor.

The U.S. is by contrast a diverse (geographically and demographically), broad culture of immigrant communities based on a concept of rugged individualism where states and townships run things as they see fit.

If you want to reshape the U.S. in the model of Japan … well

Diffusion on images is easy to understand for me: you start with noise, the model denoises by shifting the pixels towards their final value. What is the equivalent operation for increasing or reducing noise in language here?

Is the noise somehow semantic at all or is it something else?

The CPU itself is around $8-10k for a top-end AMD Epyc, $15-20k for the rest of the server, including memory and storage is probably about right. There are still $100k+ servers, but they tend to be AI equipment at this point, not the general purpose stuff, which is sub $30-50k now.

Here's an article on it:

https://www.reuters.com/world/us/trump-plans-revoke-legal-st...

> The planned rollback of protections for Ukrainians would be part of a broader Trump administration effort to strip legal status from more than 1.8 million migrants allowed to enter the U.S. under temporary humanitarian parole programs launched under the Biden administration, a senior Trump official and three sources familiar with the matter told Reuters.

> A move to revoke the Ukrainians' status could come as soon as April, all four said. They said the plans to revoke their status got underway before Trump publicly feudedwith Ukrainian President Volodymyr Zelenskiy last week.

> White House press secretary Karoline Leavitt pushed back on the Reuters report in a post on X, saying "no decision has been made at this time."

I have been calling every single person I know that has a Republican congress person and begging them to please call their congressperson on the matter. I have no idea if it has any effect. It certainly feels like shouting into the void, and there's about 1000 other things that everyone is angry about.
Providing a feeling of "safety, trust, and security" contradicts "Kids should have agency and independence." The only way they have safety is if you are with them 100% of the time which means 0 independence. I'm not worried about kids because they will natuarally avoid danger. I'm more worried about adults causing harm to kids (America).
+1 as I'm hoping this is sarcastic humor.
There is no left wing in Israel, you are painting a false narrative. It is a fascist state run by thugs (much like ours, which is probably why they are so eager to sell out Americans to Israel).

Children were bombed. They knew the kids were there and they bombed them. Often happily doing it knowing they'd slaughter hundreds to get one supposed terrorist. They bulldozed bodies. They tiktoked the destruction of universities and hospitals.

"Hamas's eagerness to put them in harm's way" is such a tired lie to cover up for the slaughter of innocent people by the Israeli terror state.
> WebGL is half-assed in safari because of "security" risks, ...

Not commenting on anything in the latter clause of your sentence, but I can tell you the security risks are very, very real. Having worked on GPU architecture as well as a browser engine -- so, so many features/guardrails/guarantees that we take for granted on desktop PCs are basically in their infancy when you look over at the GPU world. Address-space isolation, virtualization of hardware resources, separation of virtual machines, privilege isolation -- when you go to the GPU, all of that is kinda-there if you're on newer hardware, but even then without anywhere near the level of coverage or battle-testing that modern CPUs & kernels have. For example, Pascal (i.e. that old 1060 your friend is still using in their kid's desktop) doesn't even have per-process memory isolation -- a buffer overflow in your browser engine could attack any GPU process on your machine! Even the vendors themselves won't claim to support "proper" secure multi-tenancy until the Hopper era, and again -- even that's much less well-tested than the CPU-level isolation that browsers normally rely on. Consider how much of a security impact PPO/site-isolation has had: so many attacks that used to be possible (e.g. your password being stolen off of your banking site by a malicious ad in the sidebar) are now essentially impossible. That only works because of the deep strength and reliability of address-space separation in modern hardware platforms.

So to take code written by random people on the internet, in a dynamic language, JIT compile it, and then give it access to your GPU -- well, I hope you can understand why that might put the security people on edge. Again, I don't mean to dismiss the rest of your comment, but I want to clarify that when it comes to punching holes in the browser sandbox, the security concerns are really very real.

I stopped feeling hungry in the morning a long time ago. Just unhealthy amounts of coffee, without sugar or milk. If I eat even just the tiniest snack or sweet, the food processing tract will "wake up" and it's over. But if I can avoid that, I only break the fast because of convention, not because of hunger.

But it's also very contexy sensitive: currently working from a place where I usually go for high calorie throughput sports (think Tour de France climbs, but higher and a heavier rider, obviously a lot slower but the energy demand is mostly mass x elevation, almost unpacked to speed) and my body is in "eat! you will need it!" mode every day. Crazy weight gain on the working days.
Not really. My iPhone, and especially my AirPods, have gotten massive feature upgrades since I bought them, and I didn't have to pay a thing.

And I assume my WiFi router updates have helped prevent people doing evil things with my devices.

Samsung's update here is obviously a massive fail, but it's one consumer device out of tens of thousands. I think it's clear the benefits outweigh the harms on the whole. Definitely sucks if you bought this particular soundbar though.
I have only ever gained weight with intermediate fasting. When my window opens, I feel so hungry that I keep eating.

I know supposedly you adapt to it and don't feel that extra hunger eventually, but somehow not me.

If someone was building "Arc but for Firefox" I'd gladly pay for that. Firefox is, because of its position in the market, incapable of doing anything broadly interesting that's not "Be as Chrome-like as possible." They sneak in features that are nice, but I simply don't think we'll ever see Mozilla put out something that does anything that really sets Firefox apart. We'll only ever just get marginally better privacy settings or whatever the next Pocket ends up being.

Browsers are _user agents_. I want my user agent to serve me by being as frictionless as possible when I use it. I simply can't accept that what Chrome/Firefox/Edge/Safari/Opera have provided as the standard web browsing experience for the last two decades is a global maximum. We use the web in very different ways than we did a generation ago and yet Firefox 136 looks impressively similar to both Firefox 36 and Firefox 3.6. Take the gradients away from Chrome 1.0 and you could convince me a screenshot of it was their next version. If the browser is a tool, it's astounding that the tool has hardly evolved _at all_.

I miss the days when Opera did all sorts of weird and wacky shit. Opera 9 was a magical time, and brought us things like tabs and per-tab private browsing and a proper download manager and real developer tools. Firefox should be that, but they're too scared to actually do anything that isn't going to be a totally safe business decision.
Perhaps a stupid question, but why they don’t test the firmware updates internally before releasing them?
Well, it could be argued that the “optimal response” ie the one that sorta minimizes that “energy” is sorted by LLMs on the first iteration. And further iterations aren’t adding any useful information and in fact are countless occasions to veer off the optimal response.

For example if a prompt is: “what is the Statue of Liberty”, the LLMs first output token is going to be “the”, but it kinda already “knows” that the next ones are going to be “statue of liberty”.

So to me LLMs already “choose” a response path from the first token.

Conversely, a LLM that would try and find a minimum energy for the whole response wouldn’t necessarily stop hallucinating. There is nothing in the training of a model that says that “I don’t know” has a lower “energy” than a wrong answer…

>A 2010 edgelord may say "pool's closed" while a 2025 edgelord may say "it was a Roman salute", but the spirit behind is probably the same.

I think I disagree. I don't think "pool's closed" was ever boosted into the mainstream, nor was it legitimized across truly fascist or racist communities; it was an internet meme for internet people. "It was a roman salute" is a phrase of normies that likely have limited experience with computers and online communities; without getting into the politics, a certain class of people actually believe "it was a roman salute". "pool's closed" meant nothing outside of specific communities.
I find if i eat an early breakfast, it is indeed hard to not eat after the 8 hours. I find the opposite to be quite easy though. Just skip breakfast and don’t eat until around 1. I get to look forward to food later while actually being hungry.

I think pretty much because the neural engine hardware stuff was to accelerate various existing ML features (face detection, voice recognition, etc) and not any kind of foresight about how ML would become relevant for LLM-type AI features (which can mostly use the cloud anyway so local isn't that important).

There is no reputation to burn, they're well known to do this kind of stuff by anyone bothering to look it up, and nearly nobody looks it up anyway.

It's a pity because I liked some of their hardware in the past (an NX camera I still have, hard disks back in the IDE stone age, 3 LCD screens back from when they were a novelty - they only had a VGA connector) but I just stay away from them now. But 0.01% of their customers staying away is completely insignificant when they consider the profit opportunity of violating our privacy.

Thanks for sharing. Without insight beyond being a consumer, I do think there's room for disription (ideally from within the industry itself) vs 10y ago.

Comparing models from 2005/2015/2025, for example. Most people literally can't tell 4k from 1080 and anything new in the HD race mostly feels like a scam. The software capabilities are all there. I think to differentiate from the no-name stuff, longevity is going to become a more significant differentiator.

I feel like we're stacking naive misinterpretations of how LLMs function on top of one another here. Grasping gradient descent and autoregressive generation can give you a false sense of confidence. It is like knowing how transistors make up logic gates and believing you know more than CPU design than you actually do.

Rather than inferring from how you imagine the architecture working, you can look at examples and counterexamples to see what capabilities they have.

One misconception is that predicting the next word means there is no internal idea on the word after next. The simple disproof of this is that models put 'an' instead of 'a' ahead of words beginning with vowels. It would be quite easy to detect (and exploit) behaviour that decided to use a vowel word just because it somewhat arbitrarily used an 'an'.

Models predict the next word, but they don't just predict the next word. They generate a great deal of internal information in service of that goal. Placing limits on their abilities by assuming the output they express is the sum total of what they have done is a mistake. The output probability is not what it thinks, it is a reduction of what it thinks.

One of Andrej Karpathy's recent videos talked about how researchers showed that models do have an internal sense of not knowing the answer, but fine tuning on question answering I'd not give them the ability to express that knowledge. Finding information the model did and didn't know then fine tuning to say I don't know for cases where it had no information allowed the model to generalise and express "I don't know"
