There are two phenomena.

Tropospheric ducting happens at low altitudes, a lot of times in the summer across Lake Ontario, people in Canada tune into TV stations in Syracuse and I sometimes talk to them on a 2 m repeater south of Cayuga lake.

The other is a ‘skip’ caused by a dense spot in the ionosphere.

> the real cause of their symptoms was isolation from their peers

But who are their peers? Sometimes having a word for how you are can help you find other people you'll vibe with, even if it's technically a misdiagnosis. I've seen it both with neurodivergence and LGBTQ, with kids who arguably don't even fit the label but find and return great value in those communities anyway. I'm sure people here can appreciate how sometimes results matter more than adherence to inflexible rules laid down in some book.

I'm assuming you understand that my statements have a implicit "from an economic pov" when I argue about the practicality of pumped hydro storage, and you're arguing that it is economical to do pumped hydro on a small scale.

My understanding is that it only becomes competitive with other options at a very large scale. A 10 m deep football sized reservoir, at an altitude of 1km above the generator would have approx 13Mwh of energy storage at 100% efficiency (if my math is correct). Battery prices are around $140 per kWh, so a 13 Mwh battery installation is going to be in the vicinity of 2 million dollars.

I would love to see some costs involved in building two man made ten meter deep football field size dams, a large 1km length (it will be quite a lot longer due to it running on a slope) with all the required engineering to run it down a steep incline. The add to that the and generating equipment, and pumps.

Once you've done that, we could compare the operating costs of the two options.

I read the trilogy, which is actually named “Remembrance of Earth’s Past”, with “The Three-Body Problem” being the first, and IMO the weakest of the books.

<Spoilers follow>

Great read, but I can’t see how anyone would be optimistic about humankind after reading them: a group of humans who think we should be eradicated and invited aliens to do it, or at the least enslave us; collaborators when that eventually happens; and then as you mentioned, MAD, and then a series of bad, emotional decisions, all leading to near extinction.

I just can’t find any optimism in there. And it feels very realistic. I read the entire series during the pandemic, lockdowns, and the poor management of all of it, and the books resonated way too well.
This is exciting because it could reduce the capital expenditure needed for hydrogen production. The biggest reason we don't use intermittent electricity generation (wind, solar) for hydrogen production or desalination is that a significant fraction (~30%) of the total cost is capex.

The efficiency here is lower by a factor of 2 or 3 for electrical consumption (for now in the lab), but if you can get electricity at near zero cost for a few hours a day this could make economical sense.
This is one of the reasons why I like the HHKB/Tsangan variant of ANSI 60/65% in particular: it has a dedicated ~/` key[0].

It’s the “with all our stuff” part that makes it virtually impossible. The amount of energy necessary to move that much mass out of stellar orbit is beyond anything we’ve even plausibly imagined might be posible. If it is doable, it’s going to need an energy source that we don’t even have theories of.

> See how it feels, when people throw shade on something that you know well?

My feeling is mostly that of confusion. I spent several years writing OOP, and then learned pure FP, and now that's all I do. Pure FP is the best thing I have ever used for UI programming.

My confusion is not from you "throwing shade" on something I know well. Rather, it's from you throwing shade on something you — by your own admission — are not in "a position to render much judgement".

That happens too often with Forth. Someone gets interested, thinks it would be sooo awesome to add this and that "modern" feature, and then they end up with something that combines the disadvantages of Forth with the complications of what they've added. An oddity nobody wants to use, and yet another bit-roting carcass is some CVS.

It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration [1]

I think that Forth only works with people who've started with assembly programming. Someone who started with a high level language suffered that sort of brain damage that make them unable to feel complexity even when it coils around them and give them a hard time breathing.

Haven't read him until now, to be honest, but this discussion and some other recent threads from HN make me really want to start reading Georgescu-Roegen's work [1]:

> He is best known today for his 1971 The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity. A progenitor and a paradigm founder in economics, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics.

There was a HN-er who had some good comments about Georgescu-Roegen in the past, not sure if he's still active (I can't remember his username) or if he'll see this comment to add some further insights.

So... this is a fuel-cell-adjacent technology, and as such you need to read announcements like this with a somewhat cynical eye. I have no reason to doubt the science here. It probably works, or certainly is no less likely to fail than any other new technology.

But here's the thing: PEM electrolysis promises to reach hydrogen production efficiencies of... 80% or so, using exotic materials and entirely new chemistries. Regular DC electrical electrolysis (literally the "stick a wire in water to make bubbles" experiment we all did as kids) is starting out around the 65-70% mark. This just isn't that much better.

And doubly so when you realize that the most efficient reconversion of that hydrogen to electricity is going to lose another 20%.

This is better, but it's only incrementally better. 30% cheaper hydrogen would be nice, I guess, but it's not going to change any fundamentals of the energy economy.
Overall, I agree with the spirit of the post, but there is a benefit to let others fail and report results to you. If you manage to distill wisdom from their failures, you may be able to avoid those yourself and save yourself the trouble that could result.

> Even if I lost all my sources of revenue tomorrow, I wouldn't survive for a very long time with my savings

But you will survive longer than not having those savings at all. Or even worse, having debt. The extra burn down maybe the difference between accepting a shitty job or being able to look around for a better one.

I've recently experienced a family emergency and I was glad I was in position to fork out hefty some of money without even thinking about it, thanks to saving agressively.

> And if I wanted to launch some business in the near future, I doubt such an amount of money would take me very far.

Again, at least you will have _some_ run way to try something different. Savings give you options.

I feel like what you are doing is reasonable. Once you have savings (and arguably you already do), maybe take a big adventure!

There's a bit of truth yet we model the world through ideas.. I guess the important part is having an iteration process to prune or refine ideas through test/observation (science etc). It's also quite delightful to test an idea even if it failed.. it's a piece of knowledge still. And it frees you into seeking new better ideas.

Modern malloc/free implementations must satisfy requirements such as being scalable. It eliminates any chance to implement blocking deallocation from non-owner threads. A modern implementation already has to be async in some ways. You can check paper behind Mimalloc for example.
OpenGL 4 is not the “really old stuff”
My most significant piece of advice came from my uncle. It was simply this "how would you feel if your grandmother died tomorrow?". It had an immediate effect. From that moment on I began to respect and honour my grandmother.

Up until then I was not exactly the nicest grandchild, a lot of anger, a lot of confusion reigned in my childhood and my grandmother was the last in the chain. She ended up getting most of my frustration. But that piece of advice had a lasting impact, it has been with me for about forty years now.

I try to always remember that when dealing with other people not because I think I want to improve their lives, I simply don't wish to have a guilty conscience if they do die tomorrow. Of course the effect is the same as if I were to be motivated by altruist ideals.

For most people reading this it might be a nice ideal but not a good piece of advice. The reason this was a very good piece of advice for me was that a few years before my uncle said this to me, my father had died. He died without me being able to say goodbye, to be able to talk to him, nothing. I was left with a mighty large hole.

And that is the second piece of advice: some advice only works if you have had the experience. And some advice makes sense later after you have had the experience. Be open and listen to others, especially those older than you. Be polite, be reflective and be thankful for being the survivor of a long line of ancestors, not everyone gets to survive.
"Life is too short to waste your free time being somewhere that you don't want to be."

Then again, you might be surprised at who you meet when you're somewhere you don't want to be.

Too many people are shut-ins and never meet anyone, so never get the chance to meet someone who might change their life, help, or stimulate them.

I'd err on the side of meeting more people and giving them a chance, unless you're already a social butterfly with way too little time for yourself or the people you care about.

Show HN: Conv911, a social-media platform to improve at texting
This is a web app we built for fun, basically a social-media platform for people to get help with their online interactions, like answering your boss, a colleague, or just handling any random conversation.

I know some people were concerned with ethical issues with such website, which is why we made a clear guideline on the type of content which should be posted there. As an introvert it often occurred to me to spend a week before answering an email, or spend hours to answer a random discord conv, this is the kind of helpful use-cases we are aiming for.

I know HN is usually interested in more technical topics, but any raw feedback is appreciated :) The website is built with React/Tailwind on the frontend and Rust for the backend

> "Always take sides."

I've heard and read this advice numerous times, and it is even very old advice.

"Rulers must never remain neutral. If neighboring rulers fight, you must take sides, because if you do not, the winner will threaten you, and the loser will not befriend you. Whether or not your ally wins, he will be grateful to you. However, if you can avoid it, you should never ally with someone more powerful than yourself, because if he wins, you may be in his power."

-- Niccolò Machiavelli, 1513

There certainly must be something to it, but in my opinion sometimes there is a place for neutrality. If it is expressed without any nuance as above, I don't think it is good advice.
Right.

"Labor shortage" is equivalent to "rising wages".

Never internalize advice based on folklore. That means you must critically review, and mostly reject, all common-wisdom advice given to you.

People who appear to be founts of knowledge and wisdom are often fools spreading harmful folk advice just to feed their self importance.

Not all things can be known, even with our flooded-by-evidence culture. But that doesn’t validate folklore.
You talk about E=mc^2 like it was some kind of Mayan idol waiting for Indian Jones to uncover. In a way I guess that's true. But Einstein wasn't the one who placed it there, so if the knowledge is forgotten then that just means someone else will eventually get the thrill of discovery.
DisplayPort is the more surprising one. DDC came from VGA and DVI and uses the I2C lines that also connect the EDID EEPROM, but Displayport doesn't even have I2C pins if you look at the pinout, so it has to be tunneled:
"DisplayPort does not have the I2C SLA/SLC pins. Instead, the logical I2C signals are converted at each end into messages on the AUX channel. Put another way, DDC is implemented using the AUX channel, but the AUX channel itself is not DDC. The "multiplexing" of I2C over the AUX channel is transparent to all but the lowest level of I2C software at each end."

If they can make flipping a finger pinch worth of pages somehow doable that would be killer. Some sort of wide-pinch gesture with a semi transparent overlay of the page you are going to flip to with your current pinch width.

A foldable reader with readable panels on each sides when you open it. You can flip pages either way. Pen for annotation if possible. Create/edit your own documents. An icon tap to overlay another document (a note, book page, research paper) so you can add to it or copy from it to the underlying panel.

A reader mode (distraction free) when simply reading. A document mode when you are doing something that requires writing (including simple annotations).

I like books and flipping through them. However if you can blend a book reader with a great note taker that would be ideal.
Fascinating, I didn't know that ruling.

However, to the larger point, in pre-internet times if you were to enter a public forum and shout racial obscenities it wouldn't be possible to do so anonymously, I imagine you'd get cited for creating a public disturbance (possibly thrown out on appeal if you bought an expensive lawyer?), and you'd suffer multiyear reputational damage [at least in small town].

These mechanisms seem to work - I scarcely ever seen in-person behavior that sinks to the level of online behavior. And I think we're all happier for it, imagine if the public playground allowed strangers from all over the world to shout whatever phrase they want anonymously with no transportation cost.

I find the idea that unless our civilisation changes its priorities from "unbounded growth" to "homeostasis" then we necessarily will suffer the "asymptotic burnout" comparable to papers written in 19th century predicting New York will drown in horse manure in next 75 years unless the growth is artificially stunted. Although the authors mention the role of periodic innovation as a factor that resets the curve of the resource consumption they dismiss it by stating the frequency of said innovation has to increase with increased energy usage and interconnectedness resulting in a certainty at some point innovation will not be fast enough to delay running out of resources. For this argument to work we have to accept unquestionably that "unbounded growth" has to continue until either a civilisation runs out of resources and regressed or achieves "enlightenment" and shifts its priorities towards homeostasis. To this I say why are they so sure, that as through growth of economic activity we raise our collective standard of living people don't start valuing their happiness over economic output? In fact observations of highly developed societies seem to support that. In addition the birth rate of people declines in modern societies often below replacement numbers so that "unbounded growth" looks really unlikely.
I'm not yet convinced there's a problem.
AI isn’t choosing our artistic future, we are
It's a bit worse than that. What we call "technical debt" is roughly the equivalent of building a skyscraper with inferior steel and saying we're going to go back and fix it later.

The skyscraper is also a flawed analogy because it doesn't cover the fact that this will somehow magically slow down the work on the rest of the building until it is fixed. The molasses metaphor is good for that one, but I don't see how I can mix the two.
Encrypted over TLS is fine. You don’t gain anything by digesting salts, peppers, and passwords on the client side. You’re ultimately handing an string to a server, and if your backend just takes that scrambled text and compares it to a database entry, it’s no better against MITM attacks than not digesting.

You’ve also increased the complexity and bug surface area of the client-side code for any client that needs to log in.

Just don’t send plaintext passwords over raw HTTP, enforce TLS.
