I see several comments here that misunderstand "perovskites", so to be clear: "perovskite" can refer to either the mineral or the crystal structures with the same structure as the mineral. Virtually everything written about "perovskites" refers to perovskite structures; the actual mineral perovskite is just used as a rock (geologists poke at it and miners crush it up.)

Perovskite structures are interesting because they have unique material properties. The range of properties is quite broad: ferroelectric, pyroelectric, and piezoelectric properties, photoelasticity, very high permittivity, et cetera. In popular science news, you will mostly read about potential uses in solar cells, but they are already commonly used in our world: barium titanate is used as a dielectric in capacitors, lead zirconium titanate is used as the piezoelectric crystal in many resonators, lithium niobate is used for optical waveguides and for optical antialiasing filters because of its birefringence.

NATO doesn't intend to ever fight a trench war. The war in Ukraine is a useful testing ground for certain weapons but I don't think they care much about trench warfare in general. NATO doctrine has always been to destroy the adversary's air defense system first, then rely on air dominance to enable maneuver warfare on the ground. Neither Russia nor Ukraine had much in the way of functional air forces so they had to fall back on more primitive attritional tactics.

There's nothing stopping a window manager from supporting docking windows to each other, or the more common option in tiling window managers of having nested tiling groups so you can arrange your editor windows however you like and manipulate them together. Metisse [1] takes it even further, letting you slice a ‘palette’ out of one window and put it in another. In practice I, like you and I suspect a lot of other people, use workspaces in lieu of task groups, which works fine for simple use cases and small monitors.

The only applications that really need MDI are those that do something with their windows other than window management, which (loosely) implies that those things are something other than windows.

I recently worked on a few client projects that used WP/Gutternberg. I was pleasenetly surprised by how good the dev/editing experience has been compared to when I tried using Gutternberg a few years ago, some amazing work has gone into it. Sadly I still have a lot of uneasiness around what has happened over the past year. For most greenfield projects we have been using Statamic CMS

For those who still need word press, I recommend checking out the roots.io open source collective, they have done great work bringing modern PHP development practices into WP projects. Bedrock and Sage are a great starting point to any project.

Rust has a combo: people come for safety, stay for usability.

Languages struggle to win on usability alone, because outside of passion projects it's really hard to justify a rewrite of working software to get the same product, only with neater code.

But if the software also has a significant risk of being exploited, or is chronically unstable, or it's slow and making it multi-core risks making it unstable, then Rust has a stronger selling point. Management won't sign off a rewrite because sum types are so cool, but may sign off an investment into making their product faster and safer.

It’s much more banal than it seems.

Personal anecdote: I hired an exceptional H-1B worker to a role while I worked in SF, but was legally required to first advertise their role in 2 places. We put it in a 2am TV spot and a Modesto newspaper ad. But the whole thing was a legally required farce. We already knew from months of aggressive sourcing that no other qualified candidates existed - in fact we were over the moon to hire this person.

The reason slavery is bad isn't because of suffering, depending on how you define suffering. There were "house slaves" that had relatively comfortable lives. Slavery is bad among other reasons because it strips away someone's humanity and completely takes away their liberty, subjecting their life to the will of someone else. It's a constant ongoing theft of a human life, a reduction of a human life to property.

I'm glad you brought up suffering, I'm realizing better now why so frequently I hear these two ideas brought together by people inadvertently finding themselves on the same side as folks minimizing slavery in attempts to argue against harming animals (by engaging in debate about moral relativism). Purely from a suffering standpoint slavery doesn't necessarily have to be "that bad."

Drawing comparisons between it and arguments against harming animals are nonsensical because we're not talking about suffering, we're talking about other things that can only possibly involve humans. Thank you for sticking around and exploring your viewpoint with me so I could understand that better.

Matt is in large part mischaracterizing, although not outright lying about, the court's ruling. If you follow the link he provided to the ruling itself, many of the dismissed claims were dismissed "with leave to amend" (basically WPEngine has to fix their allegations), and one was dismissed for the reason that it should instead be asserted "as an affirmative defense if appropriate later in this litigation." There were some claims dismissed in a way WPEngine can't fix, but not many, and others were upheld.

I have no connection to either side here, nor am I a lawyer, but I do know how to read a legal opinion.

In case Matt removes the link to the actual ruling from his post, and also simply for HN readers' convenience, here it is: https://www.courtlistener.com/docket/69221176/169/wpengine-i...

"At the time", running on the device was a requirement.

"Nowadays", one-the-device is harder but don't we always get enough connectivity to run web-based apps? Or at least apps through a browser? Whatever device, but our own apps from our own servers? New advantage that there is not much residing on the device which can then be lost, stolen or broken without issue.

I don't understand this narrative that California has been pushing the last few years - basically, "There's a bus stop in the neighborhood, therefore we can add a bunch of new housing without doing any other infrastructure upgrades." I just don't see it. What I do see after new housing is added is insufferable traffic and no parking - and empty buses.

UTF-8 was a huge improvement for sure, but I was, 20-25 years ago, working with LATIN-1 (so 8 bit charcters) which was a struggle in the years it took for everything to switch to UTF-8, the compatibility with ASCII meant you only really notice something was wrong when the data had special characters not representable in ASCII but valid LATIN-1. So perhaps breaking backwards compatibility would've resulted in less data corruption overall.

exactly wrong. Americans are dissuaded from going into these highly skilled fields because anyone talented enough to do those things realizes they can make much more building SAASes or working on wall street.

the Boeingization of the economy is mbas and bean counter middle management realizing that an H1-B is much cheaper than a citizen and opting to buy that labor, even if it's worse quality. as management, you put an ass into a seat, so job accomplished, here's your accolade.

Agreed about Matt, completely. It should be remembered that although it's framed as a legal win, it's not THE legal win. I am not a lawyer, but I think the practice is generally to make as many arguments as the law will support up front– but not all of them were ever going to stick. And WP Engine can still remedy any deficiencies in their pleading to try to make them stick (I'll wait for legal minds to finish reading this and explain it to me, though).

A Chernobyl level incident every single year would kill fewer people than the annual number of people that die from fossil fuel particulate emissions. We can imagine reasonable numbers of accidents and still be sure that it would be dramatically safer than fossil fuels, even ignoring climate change.

And the land rendered uninhabitable would represent less land lost than is expected to be lost from sea level rise, most of which will be extremely hi-value coastal areas.

There is no way you can run the numbers where nuclear, even with dramatically reduced safety standards, is not preferable to fossil fuels. By making it so expensive with such heavy regulations, all we have done is forced ourselves to use the worse-in-all-possible ways fuel source for most of a century, causing millions of premature deaths and untold billions in environmental damages.

Over-regulation of nuclear is high up on the list of greatest civilizational blunders humanity has ever made.

I don't think we're going to see much of that:

* The projects won't be profitable in smaller towns, because rents aren't high enough to recoup the cost.

* Tall buildings cost MORE per square foot than short buildings, so tall buildings only get built where land costs are very high.

* This law's top density (7-8 floors I think?) only applies in a narrow window (0.25 to 0.5 miles) around major transit stops with LOTS of service, like < 15 minute bus intervals with dedicated BRT lanes, or trains with > 48 arrivals per day each way. Small towns don't have that kind of infrastructure.

* The law only applies in cities with > 35,000 people.
by mutator | 2025-09-13 02:58:50+00:00
The discourse around high density housing does not make it clear what specific type of development do advocates prefer. Its likely that the market will have to decide for itself, but if we end up with an abundance of just 1/2 bedroom rental apartments, targeted towards transient younger people, I fear it's just going to enrich the property management class, and families with kids/older parents looking for larger places and hoping to establish roots are still going to stuck fighting the pricing/supply wars.

> If this is true, life may be extremely common in the universe

It should be observable. Planets with life as entropy generators should absorb light from their star and reemit it as thermal radiation. More so than a lifeless planet of the same type. It is the case for Earth.

I have seen this idea somewhere, though I don't know how serious it is.

Yeah, I'm just arguing that "baseload" should be understood to be a bad thing in my comment above.

If you want to argue that nuclear is affordable as non-baseload power, because the (non-economic) cost to the environment of the alternatives is otherwise too high.... well I'd disagree because of how far solar/wind/batteries have come in the last couple of years, but prior to that you would have had a point. And you still would as far as continuing to operate existing plants goes of course.

> but only giving H1-Bs to the highest paying reqs which need them starves all of the other reqs of any possible candidates.

Then they need to pay better?

There are not 85,000 quant PhDs jobs paying a megabuck+ in spite of what many vocal people claim (and if they really wanted someone at those prices--they're more likely to just open a satellite site wherever the candidate already is and avoid the whole immigration issue). Any decent engineering salary would almost certainly qualify.

And if you can't qualify for an H1-B because the engineering salary isn't high enough, then I don't have much sympathy.

I love how we try to recreate things that are errors to add realism to something too clean. I've spent many hours in front of tape machines from analog to digital, and each format has its peculiarities when glitching. The analog formats had drop outs and other noise from the analog nature as well as things like head switching. There were also the various methods of drop out compensation like BCSP that would repeat the last good line which could lead to some interesting "smearing". Then there are other things that get imitated like when a monitor would lose sync and you'd see the horizontal/vertical blanking rolling through the screen or lose one of or swap the UV channels. The digital tape formats that had DCT blocks started displaying what this glitch art is inspired by (for lack of better phrasing). So for someone this "inside baseball", it would be a problem when these issues happened so it takes a second to get over the initial "oh no that needs to be fixed" to "that looks cool!"

Myths are just an interim stage for Sapiens. As words are illusions, so are myths, words are illusions of arbitrariness, stories are illusions of causality also arbitrary we needed to simplify explanation.

"The myth is the prototypal, fundamental, integrative mind tool ... to integrate a variety of events in a temporal and causal framework.” Merlin Donals Origins of the Modern Mind

LLMs aid us by calling attention to the illusions of the initial conditions, so the general idea pun intended is to expose the impairment of all religion and myth (and words and symbols) by automating them. This article is a perfect demonstration, the prefrontal lighting cause by a finger of god version calling out the machine automating the words of them in prediction. Ouch.

"Nothing illustrates the transition from mythic to theoretic culture better than this agonizing process of demythologization, which is still going on, thousands of yearsafter it began. The switch from a predominantly narrative mode of thought to a predominantly analytic or theoretic mode apparently requires a wrenching cultural transformation" [ibid]

>you should’ve applied through EB1

Why? If you know as much as you claim about immigration you should know that any EB1 application will dwarf any EB2 application in amount of work and documentation needed. Also, having rare skillset is not enough to get EB1, as you also might know. You need to meet a set of requirements, none of if which has anything to do with rarity of the skillset.

As a wordpress dev, yeah. I've got a small file that's almost entirely devoted to reversing stupid things he unilaterally shoved into core. Off the top of my head, full screen editing by default, the stupid 'howdy' that crops up in several places, and the silent user content edit that he added to translate Wordpress into WordPress in the content of every single wp install (no, really, go try it. And then listen to the guy talk about how user content is sacred, lol.)

And I say this as somebody who thinks that the block editor is... fine. I use it in a hybrid style, using ACF to create blocks that behave and perform natively but don't require directly using all the stupid build tool cruft.

The quintessential example of glitch art, imo, is Adult Swim's Off the Air, which compiles various short animations and music cut together with various datamoshed transitions. While the glitch stuff isn't always the central focus it definitely goes a long way towards setting the trippy vibe they're going for.

There are too many excellent episodes to list but Animals is a great one to get a feel: https://youtu.be/59QBOO6m210

I can recommend reading ACOUP to any technically minded person even if it's about history.

I haven't had the time to read this series yet but I can recommend for example his articles about the industrial revolution, making of iron and steel or sieges in the Lord of the Rings compares to read world tactics.

He has a knack for analyzing society from a systems level perspective and going into the right amount of depth for somebody who wants to understand the principles without having any background in history.

Both of your posts contain very little self-doubt and curiosity. Many points don't seem convincing, and you're consistently not steelmanning the arguments you are replying to.

This isn't how radiation works. Material doesn't get radioactive from being in the presence of a radioactive source. Contamination refers to radioactive emitters being somewhere they don't belong.

That's greater uptime than your average coal (85%), nuclear (91%) or gas (95%) power plants... https://www.nrdc.org/bio/rachel-fakhry/myth-247365-power-pla...

This, like normal power plant outages, is fine because in reality the entirety of your power does not come from one specific place, from a specific type of power. Instead we load balance over different places using the grid, and energy sources. It's much much rarer to have an extended period of cloud cover and no wind than an extended period of cloud cover, and an extended period without wind. Compound that with "over the entire electrical grid" and it doesn't happen.

And as a worst case version where the geographical and types-of-power constraints exist... e.g. if you're planning an off grid facility which is too small to justify wind power... backup generators exist.

Probably 99% of bus stations aren't relevant for SB79. I think the goal is to make it more like dense cities outside of California (NYC, Paris, Tokyo, etc) where car ownership can be unnecessary or even a liability. Public transit is a lot more scalable than cars. A train that only has 50 people on it may look nearly empty but it's better than having 40 cars on the road.

> “All I wanted was for people to take me seriously,” he repeated matter-of-factly. “They treated me like a rational human being, and they never laughed at me.”

This feels very key: If someone is hurting, that's a real hurt even if they're blaming the wrong people or seeking a false solution.

9 stories buildings are only for areas with heavy rail.

It's a lower limit for bus stops, and my understanding is that bus stations only count if they have dedicated bus lanes, <15 minute headways, and meet some other requirements. I've never seen dedicated bus lanes in a rural area (which are basically exempt for the law for other reasons) and you're lucky if your headways are under an hour lol

Hey, I'm the original author! I should have elaborated more on this constraint. First, many papercraft models do use cylindrical/conical faces - it's just something I prefer not to do stylistically. Part of the art here is the approximation, rather than aiming for perfect realism. There's also the fact that not all paper bends the same. Papers and cardboards come in various weights and textures, so they each can curve differently. Keeping only flat faces removes these variables from the assembly.

My head goes to the xz attack when I hear that Intel decided to stop supporting an open source tool, and a Chinese company known to sell backdoored equipment "steps in" to continue development, and it makes me suspicious & concerned.

This is to say nothing of the quality of the software they write or its functionality, they may be "good stewards" of it, but does it seem paranoid to be unsure of that arrangement?

The oldest script in unicode, sumerian cuneiform, is ~5,200 years old, if we were to invent new scripts at the same rate we would hit 1.1 million code points in around 31,000 years. So yeah nothing to worry about, you are absolutely right. Unless we join some intergalactic federation of planets, although they probably already have their own encoding standards we could just adopt.
