Minor similarity - I grew up near sea, and i remember the first time when inside the country i walked up a hill with an old fortress, looked around and felt something unusual and just a bit disorienting - there were no sea anywhere, just plains of fields and forests stretching all the way to horizon in all directions.

That's literally what it means. "Space for the river". In the past NL tried to contain the rivers in smaller basins so there would be more land to build on, but this backfires when there is a lot of water at once (such as two years ago). It's engineering nature but this time in favor of nature, rather than in favor of the humans occupying the borders next to the rivers, which falls under 'watermanagement', which includes controlling the flow and the level of water throughout the country.
I bought an espresso machine via Taobao last year and had to jump through SO many hoops to get it. But even with the hoops it ended up being an absolute steal - 1/10 the price of a US-based purchase.

Any idea why Taobao goes through such great effort to prevent American buyers from using the platform? (Or was I doing it wrong…? I used one of the Taobao forwarding services)
This week, I'm reading Love is a Choice by Frank Minirth, Paul Meier, and Robert Hemfelt. Read about one third of it.

I am the same as you. Although the only difference is:

1. Amazon is the never the cheapest.
2. Their search is absolutely garbage and I can't use it. I'd need to go elsewhere, find a specific product, then search to compare.

I just logged into Amazon and the last thing I bought was 2021 "Leuko Tape" for hiking since it was the only seller that had it at a reasonable price.

I am genuinely always amazed by the responses on HackerNews. It might be because amazon.com is just cheaper in general than amazon.co.uk?

You are welcome to think about the union-find structure however you prefer to think about it, but I was describing the problem I was trying to solve, for which the correct description of union find I gave above is optimal. Contrary to your mistaken assertion, no contradictions arise from applying graph-theoretical concepts in this way; there is no problem of "coherency". It's just a form of description you aren't accustomed to.

If your way of thinking about union find makes it hard for you to understand the problem I was trying to solve, maybe it isn't the best way to think about it for the purpose of this conversation, even if it is the best way to think about it in some other context.

I'm not claiming my description is the only correct description of union find, just that it's the one that most closely maps to the problem I was trying to solve.

The description can equally well be formulated in the relational terms you prefer: given a relation R, union find can efficiently tell you whether, for any given x and y, (x, y) ∈ R', where R' is the symmetric transitive reflexive closure of R (and is thus the smallest equivalence relation containing R). It efficiently supports incrementally extending R by adding new pairs (a, b) to it.

This is equivalent to my graph-theoretic explanation above except that it omits any mention of E'. However, it is longer, and the relationship to the maze-construction application is less clear. Perhaps you nevertheless find the description clearer.

What I was looking for, in these terms, is a variant of union find that also efficiently supports incrementally removing pairs from R.

Does that help you understand the problem better?

— ⁂ —

In general there is a very close correspondence between binary relations and digraphs, so it's usually easy to reformulate a statement about relations as an equivalent statement about digraphs, and vice versa. But one formulation or the other may be more perspicacious.

More generally still, as you move beyond the most elementary mathematics, you will learn that it's usually a mistake to treat one axiom system or vocabulary as more fundamental than another equivalent axiom system, since you can derive either of them from the other one. Instead of arguing about which one is the right axiom system or vocabulary, it's more productive to learn to see things from both viewpoints, flexibly, because things that are obvious from one viewpoint are sometimes subtle from the other one.
That and nobody has ever suggested that we rely solely on solar for energy needs. Wind, for example, is cheaper than solar (though solar is catching up.)
Hundreds of square km is not a lot, and the ecosystems where these systems would be installed are typically not rich havens of life. The US's power consumption would require about 6000-9000 sq km of solar panels (assuming ~15% efficiency) For comparison in the US there are about 13000-33000 sq km of parking lots, 93000 sq km of alfalfa cultivation, 69000 sq km of fallow agricultural land, and the mojave desert is about 124000 sq km. Yeah with gross mismanagement you might jeopardize the survival of some rare lizard or something, but it's a very far cry from a silicon wasteland.

Not trying to argue that the naming scheme is great, but I think they are trying to align it across multiple product lines, in which case it sorta makes sense.

They already have airpods use the same naming scheme, with the basic ones just being Airpods (without any suffix), then the next better option is Airpods Pro (the in-ear ones with active NC), and then their most expensive premium option is Airpods Max (large over the ear headphones with active NC, dial, and ability to still use them in wired mode with standard 3.5mm aux). The hierarchy is the same as with M-chips, with the most basic to the most premium being (no-suffix)=>Pro=>Max.

As a sidenote, I partially blame whoever wrote the article title for the confusion in this thread. They used proper name for M2 Macbook Air, but didn't use M2 Macbook Pro for the MBP. Dropping the "Macbook" part served exactly no purpose but to (most likely unintentionally) confuse the reader.
> How is it hopelessly elitist to call out insecure code as being INSECURE!!!

If a lot of code, written by a lot of different engineers, all ends up being insecure, it is worth asking, why is code dealing with this particular domain so often insecure?

> But why not try to EDUCATE THEM?!?

You can do that, and of course we should, but here is the thing about security:

The good guys have to write secure code every time, or else the attackers guys win.

Eternal vigilance is inhumanly hard to maintain. A better solution is to write higher level APIs or API wrappers that don't have these flaws.

> Why are you so elitist to assume people can't cope with these concepts?

Sure they can, but how many concepts can people cope with at once? Humans have a limit for how much they can juggle in their head. A huge part of software engineering is picking what abstraction layer to operate at. If I am writing code that deals with tons of string parsing and manipulation, I'd be a fool to write it in C or C++. Now I've done that when I needed the performance, but managing a massive number of strings in native code is easily 5x the work compared to using a GC language that also automatically tracks string length.

C is the wrong abstraction there. And indeed an obscene number of security holes have historically centered around string processing in C. That is because on top of managing all the business logic (which may be obscenely complicated by itself!) engineers now have to do so in a language that is really bad at dealing with strings and they have to do a lot of mental work to ensure the code is correct.

If I am manually flipping bits in hardware, well, JS can do it (I have seen it!) but honestly, that shouldn't be anyone's language of choice for directly interfacing with hardware.

(Doing that in C, really fun!)

> Calling for these features to be removed from extX, ZFS or other shows you don't understand storage technologies well enough.

I am not saying that. I am saying that the original POSIX APIs make writing secure code around symlinks hard, and I am saying that solely based on the fact that a bunch of security holes around POSIX APIs and symlinks exist!

This isn't some shocking statement. The original POSIX APIs make a lot of things hard.

That is pure fossil industry propaganda. There is no cadmium in ordinary terrestrial solar panels. The lead, if it’s there at all, is in the solder and easily recovered by a pass through a 300-degree intake process. All of the solar panels installed in California, ever, would easily fit in the parking lot of Dodgers stadium, stacked to a reasonable height. They are non-toxic, insoluble bulk crystalline materials.

Yes, I've switched almost entirely to B&M shopping, and I haven't ordered from Amazon specifically since 2019. Physical stores have limited retail space, so they have a good reason to be choosy about what they stock. It's worth a few extra bucks to me to not have to sort through online flea markets like Amazon (plus, it gets me out of the house).
that is a very good point and of course as much as possible should be generated domestically first.

If you open a high res aerial view of any random french or german city right now and look at the roofs of how many warehouses and huge structures are presently covered in PV, versus how many could be covered in PV if we really wanted to, for instance.
>for some reason

i think the scam here is that amazon or amazon sellers will pay people to warehouse product in the US, because when you're selling aliexpress goods at a 90% markup, you can afford the warehousing. and the people they're paying to run those warehouses list the product on ebay at 20% markup, on the assumption that if it sells they can make an aliexpress order and restock before the amazon seller notices their product is missing.
90% of a solar panel is recyclable. However, it's only necessary to do so once the panel is no longer economically viable, and panels are generally warrantied to produce 80%+ of their nameplate capacity after 20+ years.

In the EU and elsewhere there's a healthy market in used panels; when a large scale installation upgrades to newer/better panels, the used panels go on the market and end up in places where people don't care about the efficiency per area.
Right? We have blogs for these things. I don’t get it.
That sort of bulk change, all at once, might just be Amazon deciding to canonicalize the bracket menagerie.

And that's why Amazon isn't working to fix this problem -- because they don't see it as a problem. Despite the complaining, people still sell stuff on Amazon, and people still buy stuff on Amazon, and presumably Amazon is happy with their revenue numbers. So why change anything?
There's a lot of optimism in this article. Perhaps too much as it seems to gloss over some important details.

> Our process works by using solar power to split water into hydrogen and oxygen, concentrating CO2 from the atmosphere, then combining CO2 and hydrogen to form natural gas.

Then later it talks about how much desert there is, implying it's a great place for low-impact solar. How do the electricity and power come together and how much inefficiency is there in the wires or pipes? Presumably some of this water is likely to be sea water.

Presumably the sea water that would be needed to feed the hydrocarbon production along with the sea water from desalination (also discussed later) will have their own problems. "desalination toxic brine" has 177,000 hits on google.
Reminds me of the SICP lecture[0] where Hal Abelson introduces the concept of linguistic abstraction (or Stratified Design[1]) as an alternative to the approach of decomposing a program into a tree of well-specified sub-components/tasks, which ultimately fails to capture the essence of the problem being solved.

I do tend to prefer eBay/Amazon though, unless I'm really sure about it (bought it before, say) since the experience when it goes wrong is so much better. Amazon will refund/replace no questions asked, eBay will be a bit more hassle (MOFFBUZW type sellers tend to want to appease you with a partial refund or random plastic toy for some reason) but nothing a negative rating or such doesn't sort out.

AliExpress.. by the time it arrives I've probably forgotten I've ordered it, and if they won't offer a refund if it's no good/wrong somehow then bank might say the transaction's too old to do anything about (not sure about a time limit on credit card protections, maybe that's a better option), just generally more hassle. Not to mention the janky UX of ordering in the first place. (Why can it never guess both currency and delivery country correctly? UK & GBP isn't an oddball combination...)
