Access that costs thousands of dollars for a short trip that most people simply don't have the spare money for. The median US income is <40k/year, and healthcare + housing costs dominate most workers' lives.

Also, it's not $18/year like a subscription, it's $165 upfront -- money that could be spent on gas, food, medical bills, desperately saved up for emergencies, etc. and won't provide any benefit whatsoever to their lives unless they're taking a vacation they probably don't feel they can afford financially or in their <2 weeks of vacation time.

> in a way I haven’t seen any other software do.

It was novel once upon a time, but almost every internetworked operating system supports network-transparent files. Even my iPhone can do it.

Linux is a bit weird though: VIM has netrw which is very similar to Emacs; Gnome has a special VFS API that understands URIs, but only in the loosest possible sense of the word, and it can't work with autofs to "un-URI" something into a regular unix path, which is just sad.

But if you don't care about that, autofs can make it possible to cd /net/{hostname} and get my home directory over ssh on another machine, and works much better than tramp IMO, even under Emacs.

I like the idea, although I'll say my initial reaction to the design being a lot like LinkedIn is a little off putting, at least for me. I don't enjoy linked in ... that's putting it lightly. I might be in the minority but I kinda wish for a different layout when I see alternatives for other services.

Granted I get it, the social media layout is what it is these days.

It's a 1 storey building. Even if the vine means it will only last 50 years instead of 100 years, the risks are low and the cost to replace is low.

If we were talking about public infra where thousands will die if a structure fails prematurely, then sure, let's be careful about vines. But if a private land owner wishes to grow vines (or allow vines to grow) on their private building, I think it's fine.

That's a very Gen Z attitude that appears to be common. It's not shared among people of older generations. A 22 year old is an adult that can determine who she wants to date without a bunch of young femininst men rushing to defend her, which is what happened to my son. "May June romances" are a thing throughout history. Only recently have we expanded this to include young men and older women.

How do you know what questions to ask? How do you know the LLM is giving a good answer?

Asking questions and getting answers is only one part of learning; another, more important part, that's missing is putting it in context and laying it out in a manner that teaches the topic in a way that develops actual expertise. This is one part of the actual role of educators - which aren't going to go anywhere. To say nothing of the other benefits of an actual education: credentials, showing you can stick to something long-term, etc.

In any case, I don't disagree that LLMs can and should change education, and for the better - but I don't think universities are going anywhere, nor should they.

Anyway, if learning becomes so easily accessible, wouldn't it be even more important for employers to be able to vet potential hires? Surely companies can't be expected to interview the thousand new applicants that have put applicable skills on their resume simply because they talked to an LLM for a few hours and think that's sufficient to learn it?

I agree with this, though i'm still using Claude atm. I figure if we're aware of the downsides you pointed at then we can skip the fast changing landscape of self hosting. It keeps getting cheaper and cheaper to self host, so i'm not sure at what point it makes sense to invest.

For me the switching point will probably be when they (AI companies) start the big rug pull. By then my hope is self hosting will be cheaper, better, easier, etc.

The attack on Iran is proof Trump and Bibi are lying about Iran's capabilities, and that's the whole point: to attack the weak. This policy is the world's most epic case of reaction formation. As to the fate of bullies? They may prosper within the bounds of their games... Until something upsets the game. There's a most telling aspect of the U.S. leadership in the repetitive edicts for U.S. lead business to not respond to obvious inputs: "Thou shalt eat tariffs", "thou shall not raise prices", "disregard our intelligence", "thou shall not raise oil prices as it plays into the hands of the enemy". The pattern is obvious, there's no freedom in the markets, they're pegged and apparently must do as told, or else. But what is this or-else? Enormous collusion? It seems that Trump is a pure face of captive markets; he presents as a free actor yet knows exactly what business will tolerate with uncanny precision and disdain for governmental leadership, as if his of policy is literally the policy of business... Oooooh!

Whether the net yield of hydrogen (and nearly-sanitized H2O and Aluminum oxide slurry) is worth the squeeze.

And, Is hydrogen plasma through and within the water worth it from a just hydrogen yield perspective?

When I asked an AI about research in this - after an LLM suggested hydrogen plasma for deoxidizing titanium (instead of yttrium) the other day - there were a few results; which alone doesn't indicate viability.

What do you do with the aluminum slurry from hydrogen plasma etching and IDK ultrasound?

Ctrl-F aluminum:

"Green steel from red mud through climate-neutral hydrogen plasma reduction" https://www.nature.com/articles/s41586-023-06901-z ..

> Red mud [from aluminum production] consists of up to 60% iron oxide. Melting the mud in an electric arc furnace using a plasma containing 10% hydrogen reduces it to liquid iron and liquid oxides, allowing the iron to be easily extracted. The plasma reduction technique takes 10 minutes and produces iron so pure, say the researchers, it can be processed directly into steel. And the no-longer-corrosive metal oxides solidify on cooling, so they can be transformed into glass-like material that could be used as a filling material in the construction industry.

I am somewhat baffled at the economic models of LLMs right now. Ever since MS decided to gift me a copilot on my desktop that appears to have no limits and is entirely servicable for a range of tasks I'm failing to immediately see the monetisation.

I feel like even trying to game the LLM into creating product placement is a relatively complex feat that might not be entirely reliable. Some of the groups who spend the most on advertising have the worst products, so is it going to be successful to advertise on a LLM that is one follow up question away from shitting on your product? I imagine instead of product placement, the token tap might simply be throttled and a text advert appear in the text loop, or an audio advert in a voice loop. Boring, old-school but likely profitable and easy to control. It lets us still use adsense but maybe a slightly different form of adsense that gets to parse the whole context window.

I also worked at a factory before transitioning to programming, and can relate to everything you have said.

My research resulted in me getting an ADHD diagnosis. My brain is screwed up. It just has a weird relationship with dopamine and motivation.

Not sure if this would work for you but a low dose Adderall really helps me focus and feel good doing "slower" tasks like work. I would certainly speak to a physician if you haven't already.

I have a child, who is brilliant, and performing great at school but he is already presenting similar symptoms as myself, hopefully I can help him set healthy limits and cope without meds.

I never really noticed it until one day, while I was walking, I suddenly noticed how much denser the leaves on the old tree at the street corner had become. That’s when I realized that the beauty of life often lies in these small details. People tend to rush after big goals and forget to appreciate what’s right in front of them. Just like the article mentions, slow networks are a way to return to the essence of life, allowing us to slow down and truly sense everything around us.

That's awesome. Thanks for sharing. I use tramp periodically and had to discover some of those on my own.

> I kept thinking to myself “There has to be a better way to do this”. I have started to think of ways to fundamentally improve the performance of TRAMP that would involve changes to the package itself. I plan to write more on that soon, so stay tuned!

Will look forward to it! TRAMP is really a gem and it does feel like it should be able to go faster. Either with some config tweaks to modernize it a bit, or some improvements in the caching or the sync logic.

I think it makes no sense, but as HN discourage swallow dismissal ...

* I can't find the part about "with space as a secondary effect". Where is it? The paper just start defining everything in a space with 3 timelike and 3 spacelike dimensions.

* The easiness to test prediction is the the ratio of the masses of the three generations of particles. The paper claim they are

m_n = m_0 exp(-α n^γ)

Then then claim something like: "1 : 4.5 : 21.0"

The formula has 3 constants to predict 3 constants. So it's possible to adjust them for each family of 3 particles. It's not clear how the constants are calculated and which constants are shared between the different families of particles.

- top/charm/up quarks: the ratios are 1 : 588 : 80186 Note that the mass of the up quarks is much smaller then 1/3 of the mass of the proton or neutron. That's standard. https://en.wikipedia.org/wiki/Up_quark#Mass These masses are very difficult to measure experimentally. The article claims 2.16 ± 0.49 MeV but from Wikipedia:

> Despite being extremely common, the bare mass of the up quark is not well determined, but probably lies between 1.8 and 3.0 MeV/c2. Lattice QCD calculations give a more precise value: 2.01±0.14 MeV/c2.

- bottom/strange/down quarks: missing(?!)

- electron/muon/tau: 1 : 206 : 3477 These values have a extremely high experimental precision. The article claims 0.5109989461 ± 0.0000000031 MeV but Wikipedia says 0.51099895069(16) MeV/c^2

- neutrinos: From the article:

> For neutrinos, this work predicts masses of 0.058 ± 0.004 eV for ν 3; 0:0086 ± 0:0003 eV for ν2, and 0:0023 ± 0:0002 eV for ν1, with mass ratios showing remarkable precision: m2/m1 = 4.5 ± 0.3 and m3/m1 = 21.0 ± 1.5.

But from the experiments we have only upper bounds of the masses. We know they have mass, but we don't know even an approximation of the value. From https://en.wikipedia.org/wiki/Neutrino#Flavor,_mass,_and_the... the experimental values are "<0.08x10-6", "<0.17" and "<18.2" so I don't understand how the paper claims "remarkable precision"

10 year procurement process and 10 year purchase windows tends to add a price premium.

That said, the rivian delivery van is in the neighborhood of $85k-$90k [1], so not that far off price wise, and the NGDV has a lot of design elements that make it more precisely matched for how the USPS uses delivery vehicles. The article I linksd does point to a much less expensive Ford E-Transit, but it's still not built around the USPS's needs.

It is a very special piece of work. The closest I've seen is vscode remote editing (and credit where it's due: vscode remote editing is out of the box far more reliable and stable than Tramp... it better be, since it's running its own daemon on the remote machine), but Tramp is far more general-purpose than vscode's solution.

Editing as another user, editing a remote file, even editing over embedded protocols like adb: Tramp's got you covered.

Surprising. I'm 54 and the coming ice age was pretty widely published in my childhood. Lenard Nimoy had a movie about it, it was in Newsweek etc (and before you laugh, Newsweek was "real news" back in those days and my parents had a mail subscription).

I remember being extremely worried about it as a child and thinking "I am the last generation to know civilization as it has been before the world freezes over!"

It probably goes without saying but I haven't been especially concerned about global warming this go around.

a romantic idea. I've managed to achieve a kind of Walden / Wonko the Sane way of life in tech, where I work by a picture window looking out on a large field on a farm, and I in fact chop wood and get my water from a well, actually.

the way I use tech now is mainly trying to get LLM agents to work to shorten the daydreaming process by giving me the answers I need. the thing is, tech is just for building more tech. it only builds upwards on the stack, and doesn't yield discovery or growth outside it. it doesn't make me a better musician, horseman, hiker, motorcyclist, lifter of heavy things, or friend, etc. these things are only the effect of practice.

maybe the response is not so much a kind asceticism where choices of taste in tech or opinion become a proxy for purity, but to ask, what have you physically practiced vs. merely consumed?

> The best way to work is managing several Git worktrees with agents running so you aren't stuck waiting 20+ minutes for Claude Code to finish.

Sounds like you're limiting yourself to users who are comfortable paying 100-200$ monthly subscription or even thousands per month for API prices.

C.C. is expensive but i was hoping we weren't going to build tooling that exacerbated this issue simply because for some of us money is less of an issue than for most of us.

Mostly the water is more or less safe but chlorine is added in many countries. That won't kill you but it's not very nice. And those big containers of water are affordable enough that they are preferable for cooking/drinking. I'm currently staying in Portugal and I'm buying a lot more water than I normally do. Back in Germany, the tap water is fine. But I do buy a lot of sparkling water because I like drinking it. Also, my urologist mentioned that bottled/filtered water is a great way to reduce the chance of kidney stones. The same calcium deposits that eventually destroy your washing machine might cause you some issues with those. So, there's that.

Yes, let's everyone look up the "freestanding" concept in N4950 section 16.4.2.5, and take note how it requires both exceptions and RTTI. Is that what you meant by "C++23 is not abandoning embedded"?

Yes, compilers support turning off exceptions and RTTI, for a long time now. C++ language does not. They could have supported it, but have chosen to explicitly not, as seen in the above section from the standard.

Nothing the committee does seem to support embedded. I will be glad to be shown I'm wrong.

So what exactly is the "AI lifestyle subsidy"? The article doesn't seem entirely clear on it seeing as the last line essentially asks this same question. Some friends and I have been taking advantage of cheap GPU time from a company trying to break into that space, and of course lots of AI tools are being sold below cost but is that really it? Compare "GPU time is cheaper" to the classical "$10 steaks delivered directly to your house", I'm never going to get steaks delivered at the real price but I'm still going to rent a GPU when I need it even if the cost is sustainable. All these tools might get more expensive, or the models will get better so you don't need top end one, or maybe we'll just figure out how to run models for cheaper, but real steak prices and the cost of delivery have only gone up. I just don't think this is quite as comparable.

> Yes they are. The summons part is essentially what happens when a cop issues you a ticket..

They are reporting, not regulating. You don't get a ticket from a random person.

> The more I read about it, the more it seems like a great scam, though. Film trucks, make them appear to be running for a couple of tokens and drown your competition in fines. Once a day on some trial will likely be enough even.

This rule is in place for a long time. It isn't a scam nor is what you dreamt up happening.

I don't think there is a point there. In case of the Tor browser, they use the user agent to blend in, so they are not a good candidate to do anything about how stupid the user agent is.

It's the current heavyweights who could change it for the better: Google and Apple. If either introduced a major change in how they present the user agent, websites would be very quick to adapt (if they need to in the first place...), or else. Otherwise, no change will happen - and I think this will be the case, same as with the HTTP "Referer" (misspell of "referrer").

Fun fact, non-browsers actually have much nicer user strings. I run an internet radio, and there is a lot of clients like

Linux UPnP/1.0 Sonos/85.0-64200 (ZPS1) Nullsoft Winamp3 version 3.0 (compatible)

Echo/1.0(APNG)

Some of the rail operators show diagrams with dimensions, although I'm having trouble finding it for Amtrak and Via Rail, it's like they don't want to show that anymore. Here's an example of what they used to show on their own website, but from a third party reseller: https://canadarail.ca/via-rail/the-canadian-train/sleeper-ca...

I think once our railcars actually operate, it would be a good idea to show something like this - especially since it allows showcasing that the seat is basically bigger than a first class seat (almost 60cm wide vs 45cm). But the dimensions keep changing around, so we don't want to make false promises for the exact dimensions.

But the goal is that all beds at least have 2m length, even if narrow at the end.

> Given that DHEA-s is a precursor of testosterone, our finding is consistent with a recent warning from the FDA that testosterone products may increase blood pressure in men

The bottom of the article seems to try to draw a link between high DHEA and testosterone and blood preassure.

Might be a bit of a leap, but higher DHEA -> higher testosterone -> higher blood pressure seems to be the takeaway?

This study [0] also links DHEA to higher IGF-1, and IIRC high IGF-1 is also linked to higher rates of cancer.

IGF-1, testosterone, estrogen, etc... they all seem to have optimal health benefits when in an "ideal range". Too low is bad. Too high is also bad. No free lunch it seems.

I just released a very minor update to one of my iOS apps.

The approval took 3 days. It hasn't taken 3 days in almost a decade.

The Mac version was approved in a couple of hours.

I'm quite sure that the reason for the delay is that Apple is being deluged by a tsunami of AI-generated crapplets.

Also, APNS server connections have suddenly slowed to a crawl. Same reason, I suspect.

As far as I'm concerned, the "subsidy" can't end fast enough.

Makes no difference how visible it is if you don’t understand the risk and do nothing until something happens. And the longer you wait, the harder it will be to remedy.

Yes. Also you can look at falling rates of entrepreneurship in the United States and connect the dots with the article. We have some neighbors who wanted to run a flower shop out of their garage. Can't get business insurance because it's not a separate location - i.e. your home and business cannot be the same place for physical goods.

Issues like that, while perhaps sensible to someone, are barriers toward economic prosperity.

But a new oil change location? Approved, insured, permitted in 5 minutes. Construction done in 2 months.

We're really hellbent on making anything but the new highway to the new Wal-Mart and $60 Starbucks dinner (paid over time of course) for the kids on the way to soccer practice in the Jeep Wagoner illegal.

>Actually, no one is capable of 'buying' a law. Laws are passed via the processes of the legislative system. Sure, you can try to bribe someone like a Congressman into voting for or against certain things, but this is very different from just buying a law outright, and people are constantly watching Congressmen to ensure this kind of behavior doesn't get too out of hand.

What unproductive pedantry. I find your comments exhausting because of their wordiness that stands in contrast to the ridiculous assumptions that your verbosity hides.

So stoked for this observatory to go online! One cool uses it'll excel at is taking "deltas" between images and detect moving stuff. Close asteroids is one obvious goal, but I'm more interested in the next Oumuamua / Borisov like objects that come in from interstellar space. It would be amazing to get early warnings about those, and be able to study them with other powerful telescopes we have now.

This blog post makes a historical analogy, which at best is useful for imagining what might happen when investors become less giddy about funding AI.

There are underlying trends that are directly opposed. Efficiency is improving, but with agents, people are finding new ways to spend more. How that plays out seems difficult to judge.

For consumers, maybe the free stuff goes away and spending $20/month on a subscription becomes normalized? Or do costs decline so much that the advertising-supported model (like Google search) works? Or does inference become cheap enough to do it on the client most of the time?

Meanwhile, businesses will likely be able to justify spending more.

It depends on how much autonomous driving they actually do. My guess is that they will only drive a miniscule amount in favorable conditions for the foreseeable future. That would maximize the hype:risk ratio.

It's also possible they quietly rely on remote operators to a large extent. The fake robot PR stunt wasn't even that long ago, the company might try the same thing here.
