PV installations on roofs typically have around 10-20kW peak output.

Let's go with 10kW. That's around 25 panels, each outputting 30V with something like 13A. Small installations are typically single-stringed, so you end up with a voltage of 25*30V=750V with 13A DC. That's pretty likely to kill you within milliseconds if you mess up.

There's a reason that stuff tends to be handled by professionals. It's a ridiculous (and pointless) risk if you aren't well educated about it and have some experience.
If it was uniquely an historical question then another text file to handle AI requests would exist by now, e.g. ai-bots.txt, but it hasn't and likely never will, they don't want to even have to pretend to comply with creator requests about forbidding (or not) the usage of their sites.

Solar would better be considered solved when the companies installing it don’t require large loans, liens on your home, and door to door salespeople. It’d be nice if having it installed was more similar to having a plumber or regular electrician stop by

That is what a "lossy compression" means. Instead of encoding the original image, you look for a similar image, that can be losslessly encoded into a smaller file.

In PNG, you look for an image with 100 - 200 colors (so that colors repeat more often) and losslessly encode it with DEFLATE.

In JPG, you look for an image with with a reduced description through DCT, and losslessly encode it with Huffmann trees.

Yeah if people get to extensive about blocking then we're going to end up with a scenario where the web request functionality is implementing by telling the chatbot's users's browser to make the fetch and submit it back to the server for processing, making it largely indistinguishable from the user making the query themselves. If CORS gets in the way they can just prompt users to install a browser extension to use the web request functionality.
I love all the little Easter eggs that make their way into academic papers. 42 is now firmly entrenched of course as the “default number“ in virtually all examples. And paper that I have under review, I tried sneaking in a few references to Zork.
> there's nothing that seems to be fundamentally unobtanium here

Don't you think this is begging the question? The entire history of humanity is a lengthy series of discoveries that people of times past would have little reason to think possible, and in some cases are revolutionary enough that it would likely have been all but impossible for people of times past to even think of them.

Then there's just the boring things, like aspirin. If not for the willow tree, it would not exist today. Ancient medicine dating back 2400+ years recommended chewing on willow bark to treat fever or pain, and indeed they were right. Of course we can now easily synthesize it, but that's not always a given for every compound or 'thing' imaginable, to say the least. For an obvious example, see: uranium.

And now factor in how extremely negligible our knowledge of anything outside of our own planet is. We've been sending probes and rovers to Mars since 1962. We only discovered the soil on Mars was relatively moist (2% water by weight) in 2013! 50+ years to figure out there's water in the soil. And the latest drills can only go a couple of inches deep and are scarcely used in any case, because they tend to break. It's impossible to know what you don't know, but I see every reason to think that it's probably quite extensive.

I stopped watching and reading the news, in general. I have some friends who balked at the idea when I mentioned it. They'd say, "Oh, but how do you keep up on important news?"

I don't.

My life is better for letting it go. If something is genuinely important, and I really need to know - I always end up finding out somehow.
Far more Chinese leaders have spent time in the US than vice versa. Many top Chinese communists have degrees from US universities. I don't think you can find a single US politician or top civil servant with a degree from a Chinese university.

I am not saying that US politicians should go and study in China but the claim of equivalence in counter party understanding is just not true at all.

The Chinese hawkishness today is reaction to the changed attitude of Americans, they were (naively) hoping for the better all the way up to the Biden admin; the experiences of 90es/early 2000es drove China closer to the west regardless of the events you mentioned.

I have truly benefited from playing Factorio.

It sets you up with a logistical mindset, you learn to think about setting up a "supply chain" before you do something. This becomes a very abstract skillset that you start to apply in multiple areas of your life.

Secondly, it takes your thinking to a higher, more abstract level when you learn to build factories that build factories that build...

Thirdly, you learn polymorphic thinking in a high level. Like, products that are then taken through different processes produce entirely different things, and then some of them are fed back to this system.

I have played the game for low two-digit hours, but it augmented my thinking in a concrete way.

I will highly recommend Factorio.

Chess has also benefited me in being more far-sighted in shorter terms. Especially in situations with real rivals, or even without.

Scrabble had helped me learn in an early age that clever tricks and pragmatism help me win more than qualities like "elegance", etc. It was a lesson 'thrown in my face'.

Ask HN: How is Square able to group emailed receipts?
I setup my square account to automatically send receipts to my e-mail if I pay a Square enabled vendor with a specific card. I notice when I receive the e-mails from Square, they are grouped nicely into a single conversation.

I inspected the e-mail headers and couldn't figure out how either Square is sending the e-mail so that my e-mail client knows to group them into a single conversation or thread.

What's even more neat is that if I have multiple e-mails connected to my client, and square happens to send e-mails to 2 or more of those accounts. In the "All" view, I would see the e-mails across different accounts in a single thread.
Same, for sure!

Moisture heat and light all tend to degrade perovskite.

A lot of the public website content targeted towards consumers is already SEO slop trying to sell you something or maximize ad revenue. If those website owners decide to stop publishing due to lack of real human visits then little of value will be lost. Much of the content with real value for consumers has already moved to sites that require registration (and sometimes payment) for access.

For technical content of value to professionals, much of that is hosted by vendors or industry organizations. Those tend to get their revenue in other ways and don't care about companies scraping their content for AI model training. Like the IETF isn't going to stop publishing new RFCs just because Perplexity uses them.

It isn’t going to make something economic that previously wasn’t. If the costs are sufficiently low (unlikely) it might have positive ROI in some scenarios.

Generally though, solar projects are go/no-go due to things like cost of money and electrical sales pricing agreements + site specific variables like insolation, flatness/road access, cost of local labor, local weather impacts on racking costs, access to transmission, and bulk wholesale costs of materials.

It’s hard to beat flat land out in the open desert near major urban areas with nearby highways and transmission lines, for instance.

What you’re talking about is likely at most half a percent of that equation.

Corporations are legal persons, which are not the same as natural persons (AKA plain old human beings).

The law endows natural persons with many rights which cannot and do not apply to legal persons - corporations, governments, cooperatives and the like can enter into contracts (but not marriage contracts), own property (which will not be protected by things like homestead laws and the such), sue, and be sued. They cannot vote, claim disability exemptions, or have any rights to healthcare and the like, while natural persons do.

Legal persons are not treated and do not have to be treated like natural persons.
Really straightforward structure
>That isn’t trivial.

Thank you. So often when discussing solar (or EVs) we see bizarre extrapolations of potential install rates that don't account for the fact that huge swaths of the country (the majority of places here in Canada) have real challenges with installation. These are not insurmountable, by any means. But those challenges are reflected in overall cost, making some of economics less favourable.

> Other 4 year olds are ignorant/impulsive/insensitive but not yours

no, all 4-year-olds are. it's a major reason adults discriminate against them. but it becomes much worse when it's not just you but everyone around you

> leting kids learn this skill at a more usual pace.

for almost all of human history, the usual pace left adults unable to read without moving their lips, or at all. either the pace you're used to is suboptimal, or that one was, but more likely both. to know which direction is better, you have to listen to people whose experiences diverge significantly from what is usual. there are lots of us here in this thread, and we're unanimously telling you that what is usual is below what is optimal. so far below, i'd say, that you could reasonably call it institutionalized child abuse
Ah cheers, that's helpful! I don't really use symlinks that extensively myself (at least not in that way).

I implemented it in an earlier version; one reason I removed it is so I can re-use -L for "don't show link target" because I had a symlink with a very long link target. The -w to set column width and/or -trim to not wrap to the next line solve the same problem, so this option is now somewhat redundant (or at least, doesn't need a short one-letter "quick to type" flag).

I'll probably put the standard -L behaviour back.
How? Real people read all millions of pages of internet texts to verify it?
A game jam is like a weekend hacking event where a bunch of people make small games in a short time frame and then get feedback or compared. A demake is a remake but usually for older systems or in an older style / lower resolution. In the indie game scene lots of the big hit games were first created at a game jam. No tomfoolery, they're useful words to describe things, that don't have other easy ways to describe.

The document does appear to exist in several libraries according to WorldCat [1], though the list is quite small. This entry explicitly lists the publisher as "International Business Machines Corp., Boca Raton, Fla., 1983", so it appears to be what you are looking for.

The Library of Congress does not appear to have a copy in the main catalog, but that does not eliminate them having a copy in the technical reports department, though finding it through the technical reports department will be impossible without report numbers or other identifying information.

If you are looking to buy a copy, you may be in luck. A search for the title in AbeBooks [2] pulls up one seller (Sleepy Hollow Books, Huntington, VT, U.S.A.) for 33 USD plus shipping. It is impossible to tell if this is a copy of the IBM or Atari edition, though. You may want to contact the seller, which is possible on AbeBooks.

Good luck with your search!

All kinds of critical systems, but how critical they are it depends both on domain and contracts.

Rather well known is payment processing, but also sensitive document chains, legal documents, but it might also be game saves (this one from experience: game progress was graded).

Sidebar and perhaps slightly off topic. One of the trigger moments in the Nazi's rise to power was the USA's stockmarket crash, and how the side effects of that ripped a nasty hole in the German economy.

In watching the Netflix doc on the eise of the Nazis, it enlightening how many actions (and inactions) of the USA contributed to the rise of the Nazis. No doubt Hilter & Co were an evil bunch but in terms of popular support and rising to power, they did not do it alone. They had plenty of help.

Long-running transactions are an antipattern, to be sure. Whenever I find one, I try to split it into smaller, shorter-lived ones.

In some cases it's tricky because you lose transaction isolation; think of a data export, for example. To preserve snapshot consistency you have to rearchitect the data model itself to become temporally aware. Or the opposite: A big import that must be atomic has to be rearchitected so that the ingested data is not integrated into the running system until you "flip" something at the end.

These workarounds should be unnecessary — these things are what ACID transactions are for, after all. As I understand it (I could be wrong), long-running transactions are not such a big problem in other databases that use in-place updates with undo/redo logging.
Agreed – I actually think that the medium of watercolor is oppositional to what makes a lot of plotter art appealing to me. I am attracted to the plotter’s mix of inhuman precision with artifacts from the interaction of the tool and the surface. With watercolor you’d have a tough time retaining the precision so you’re left with something that’s hard to distinguish from what a human could do. Would be interesting to investigate how to bring back some of that precision as it would be something I don’t think I’ve seen in watercolor before.

Lamotte is a very pure example of a journalist. The fact that he, during the later part of his career has been funded by small donations from the general public is only in his favour. That he worked for a large mass of people is something positive.

The ECHR is great and I believe that both these cases, if the people convicted had sued Sweden in the ECHR, then Sweden would have lost.

However, Swedish law is still Swedish law. Parliament is sovereign and can what it likes, legal as illegal. It'd be great to have an ECHR judgement against Sweden in one of these cases, it would have given weight to the need to change these laws into something with respect for truth, giving us a chance to throw away the tradition of the courts to regard reputation as something belonging to a person, when reputation is other people's beliefs. There should only be protection against reputational harm from falsehoods.

The amount of AI bots scraping/indexing content is just mind boggling. for my books site https://thegreatestbooks.org, without blocking any bots, I was probably getting 500,000~ requests a day from ONLY ai bots.

Before i moved my dns to cloudflare and got on their pro plan, which offers robust bot blocking, they were severely hurting my performance to the point that I bought a new server to offload the traffic.

> the morality of memory allocation as it relates to market economics … that you could only produce if you are truly clueless

I’m actually very curious to see that! I’m not sure what the angle espoused there is, but it seems fun at least from the perspective of academic science and technology studies to consider. This person might be going through a few too many scales to make meaningful commentary there though… In any case, there can be interesting connections and bidirectional influence found between technical systems and social organizations/politics/commercial industry, especially when it comes to things like how standards are defined over time. Even selecting the standardized sizes of containers for shipping and the technical design of connectors between shipping containers/cranes for picking them up has an interesting social and economic history that touches on questions of changing relationships to labor in post-war America!

This guy might be spouting total nonsense, but it seems interesting and fun to read either way!

Edit: I’m also not sure why trying to understand relationships between technical entities (like a programming language) and the systems it exists within, even if misguided, disqualifies the outputs of this person? Maybe there are plenty of other reasons, and maybe what they were saying was in fact batshit, but with zero context, I’m genuinely curious to learn more about what was said that was so crazy!
Oops, yes I did.

For curious readers: `2` is a quaternion, but `exp(2)` doesn't generate a rotation, it generates 7.389... just like normal exponentiation on reals. So if you have a real term in your lie algebra, it will generate things that scale the object as well as rotating it.

So instead you want only `ai + bj + ck`, as `exp(ai + bj + ck)` will always have magnitude 1
These efficiency limits are true for P-N junction solar cells. There are other solar cell types which can ultimately achieve higher efficiencies, but they are currently lab curiosities with low efficiencies.

Its so wild to me that the business models of newspapers and journalism in general just dont translate well to the web. Like I get that people expect content online to be free and the alternative sources of information are freely available but its just so tragic. There are so few journalists who do investigative journalism in countries that are smaller because the ad revenue just isnt there.

For example, there are a few youtubers who do a great job but their appeal is global - or at least the entire english speaking population. The scope of focus is “interesting conspiracies that are true” or “some product everyone wants”. Not a serious investigation into the misallocated funds in the local county.
This is why this conversation is making me insane. How are people saying straight-faced that the user is requesting a specific page? They aren't, they're doing a search of the web.

That's not at all the same as a browser visiting a page.
