> The sale value won't stay flat unless you tax land (or use leasehold like Singapore), because typically incomes rise, and in most places the rate of building new housing has an equilibrium lower than the rate of demand, because profit is needed for private developments to go ahead.

Developments can be profitable without the price per unit significantly increasing.

Suppose that an existing unit is $50,000 and it costs $150,000 in construction costs including profit to replace one unit with four. Then you have a stable equilibrium; a construction company could buy one unit for $50,000, convert it into four, sell them for $50,000 each and net $150,000 which covers their costs and profit. They'll stop doing this if the price per unit falls to $45,000. They'll start doing it again if the price per unit rises to $60,000 and keep doing it until it gets back down below $50,000. Therefore, the price per unit remains stable at ~$50,000, even if demand increases, because that just triggers more construction as the price temporarily gets slightly above the breakeven point.

This is why zoning restrictions cause housing costs to increase. If you declare that 95% of the land is zoned exclusively for single-family homes, you can't replace one unit with four or even two in any of those areas. Then the remaining 5% of the land already has a 20-unit complex on it and in order to add units, you have to replace it with a 30-unit complex. Taller buildings require more expensive materials, you've had to demolish 20 units instead of one and only increased the number of units by 50% instead of 300% and land on which you can even do this at all is now more scarce so you're paying even more per unit for the ones you're going to demolish. Now the breakeven price for new construction is $500,000/unit and if growth continues it has to rise to the level that can cover the cost of demolishing a 30-unit building to build a 40-unit one, even though 95% of the local land is still single family homes.
The entire concept of causality and entropy as something that happens in a linear progression at approximately the same rate is 100% a concept that is "made up" insofar as it is, as Kant would put it, the process of apprehending a sequence of sensibilities into a schematized understanding of the objects around us. Cause and effect are real (and don't require empirical understanding), but only viewing objects in the space around us as partial impressions that are contingent on that specific time is the "man made" part of subjectivity.

So a better way to put it is that time is real, but only as it relates to our perception. And that is always subjectively contingent. The concept of "time" outside of any subjective perception doesn't really make sense. Even if you're purely limiting it to "causality", then you're going to run into a host of issues if you think you can order causal interactions into a linear "time"line.
Can you imagine that some people feel differently than you? There are in fact many people who enjoy living in apartments.
Sound being a highly subjective term, I will grant vinyl can sound “warmer” on an A/B test but it does not sound “better” as a standing point. Every system “colors” sound to a certain degree - a la Beats headphones artificially enhancing the bass profile to suit market fit - but when talking quality, no, vinyl is still a problematic medium.

Show HN: How I Built Ppt.ai to Solve Presentation Pain Points at Work
I recently launched PPT.AI after a journey that began with workplace frustration and led to an AI-powered presentation solution.

Origins in Workplace Frustration

At my previous company, I spent countless hours creating presentations weekly. For one important client proposal, I pulled two consecutive all-nighters. Though successful, I wondered: "Why, in 2024, are we still creating presentations in such a primitive way?"
From Rough Demo to Validation

I built a simple command-line tool during weekends that could generate basic slide content from outlines. Despite its limitations, colleagues who tested it were enthusiastic:
"This already saves me at least half my time." "If you added automatic chart generation, I'd pay for this."
This unexpected validation made me consider turning it into a real product.
Securing the Perfect Domain

As the project gained momentum, "PPT.AI" seemed the perfect name. I discovered someone was selling the ppt.ai domain and, after negotiation, purchased it at a reasonable price. It was a significant investment for a side project, but I believed in its potential. Now, https://ppt.ai is our home, and I'm hoping the product's success will justify the domain investment.

Building a Team

I realized this project required expertise beyond my own. I recruited three friends with complementary skills: a machine learning expert, a UI/UX designer, and a backend developer. Together, we tackled four key challenges:
Intelligent Content Generation for different industries and topics
Layout and Design Awareness for visual consistency
Automated Data Visualization
User-Friendly Interface for non-technical users
Market Traction

Three months later, we launched our MVP at ppt.ai. Early users reported a 65% reduction in presentation creation time, with satisfaction scores of 8.7/10.

Today, PPT.AI has:

25,000 monthly active users
68% weekly retention
A team of 8 focused on development and growth
We've just completed seed funding to enhance our features further.
Looking Forward

Products that solve real pain points often resonate strongly. When users tell us our tool freed them from the PowerPoint nightmare, I know we're on the right path.
What challenges do you face with presentations? What pain points could AI solve? Try ppt.ai and let me know your thoughts!

[I'm the founder of PPT.AI and will be around to answer questions]
> This isn't the anti-interventionism of principled peace activists; it's naked realpolitik stripped of ethical pretense.

Yes, because ethics is a terrible basis for foreign policy. Who made you the god of what’s right and wrong, moral and immoral? The ideological nutjobs are worse for the world than the self interested dictators.

> Opposing misguided interventions doesn't require embracing callous isolationism.

The problem is interventionism itself. You’re arrogantly presupposing you understand the world well enough to intervene in the fate of foreign people. It’s the classic liberal conceit.

> Strange how your selective anti-interventionism consistently aligns with Russian strategic objectives while claiming to represent American interests.

It’s not just Russians: most of the world would prefer the U.S. to simply leave it alone. That’s why BRICS is a thing. And the anti-interventionists finally have a majority of Americans opposed to spending American lives defending the borders of countries they couldn’t find on a map. The american people and third worlders have common cause in opposing the liberal internationalists.
no, i think the prompt was too long. It said "running..." but never showed any results. I think an AI that could spit out a compelling movie that follows the hero's journey like star wars, or the matrix, or The Wizard of Oz, etc. would be really compelling. Like click a button a get a new original 2 hour movie script you could sell to hollywood? Amazing.
The purple fringes of the congressional GOP would be crucified by their constituents if they were doing this shit, which is why it is sitting back and letting the executive do everything that the party always wanted, but couldn't, while they keep their hands free.

The legislature could stop this, yes. But it won't, because he is carrying out the program the GOP always wished it could have done, but couldn't. Once this all goes to shit, they will of course, blame him, while keeping their own hands clean.

And given just how fucking fast a dedicated executive can destroy anything it doesn't like, there's literally nothing the Dems could have done to prevent this. It doesn't matter what laws they passed when they had control of government, when the current executive simply doesn't follow the law.

And the only people who could compel it to follow the law don't want it to.

The only cure to this is never voting red, under any circumstances, for any position, in any race. It's been fully compromised, and is unsalvageable.
Dynamic range compression is often used on most mainstream music because said music is rarely listened in perfect conditions in one's living room. They need to sound decent enough in the street, in a car, on a metro/train during rush hours, in the kitchen while cooking, on the beach, from allkinf of devices from crappy smartphone headphones, phones and computers integrated speakers or cheap bluetooth speakers.

Ideally one would own 2 different recording of the songs they like. One for good listening environments and high quality equipment, one for more hostile environments. Or have devices that apply dynamic range compression on the fly when needed.
Condos built and decorated in the 1970s are approaching a million dollars in our neighborhood. New ones are two million. Do tell.
You very very likely won't be able to decode a 13660×768 video fast enough.
I think you missed my point. Or are you saying that if I pay with PayPal instead of Stripe, OpenCollective gets themselves more money?

The way most epigenetic changes have been observed to work, is that information is collected by various "setup programs" (genes that activate on a timeline, and then silence themselves after "running.") These "setup programs" run only during development — usually natal development, though some of this occurs as late as early childhood. And these "setup programs" store the resulting calculated "flags" as modifications to the epigenome.

Crucially, because these "setup programs" silence themselves after running, these "setup programs" each only have one opportunity to run, at some genetically-defined point in an organism's lifecycle. The information is only collected once. Whatever this "setup program" observed at that point, that's what the epigenome records. There is no second chance to set it differently.

I don't know much about this violence finding, but one famous finding in epigenetics is that mammals whose mothers were often food-deprived during gestation, end up with a marker that correlates with the phenotype of eating more / being more food-motivated / tending more toward gathering more food than is necessary for their immediate satiation.

At least in the case of this food-deprivation finding, there is nothing you can do to/with the animal afterward, that reverses the impact of this epigenetic change. The animal's body doesn't go back and re-evaluate whether or not it "should" be more food-motivated, because the fact it's basing its food-motivation calculations off isn't about what's true now — it's about what was true then. The marker doesn't mean "the environment is currently food-poor", it means "the environment was food-poor when I was -6mo old."

(In fact, these early-natal-development epigenetic markers aren't even necessarily what you might call runtime flags — they're more like an #IFDEF statement in the DNA "codebase", their values first calculated during the long, continuous "build process" of development, and then macro-expanded later in that same build process to hard-code other things — e.g. how certain proteins/tissues and their chemical receptors get built. By the time a baby is born, that marker might actually have no further relevance, having done all its work and made its downstream impacts during gestation. If we had "epigenetic CRISPR" and turned that marker off in an adult person, doing so would only impact whatever that gene does after development — which might be "nothing.")
Reading this you'd think we're on the cusp of the sort of utopian society seen in Brave New World. Class hierarchy reinforced by behaviour regulating drugs given to happy, subservient workers. Hell, with all that talk of impulse control, I wonder what it will do to people's motivation to protest and riot...
Can extensions to be used for implementing those (and other) features? I think that they should be implemented as extensions, that they can then be replaced with other implementations (or disabled entirely).
This is helpful as well because it at least alludes to the data structures: https://github.com/pizlonator/llvm-project-deluge/blob/delug...

One more thing: I assume the memory allocator has a somewhat efficient way to recover the pointer to the start of the allocation from a pointer inside it, for interoperability with the legacy C world. For recompiled code, this is not used because the capability is either tracked in registers, or loaded from the shadow memory.
What does this even mean? The results of GLP-1 meds are well studied and widely understood to be game changing and likely revolutionary. The other claims might be hyperbolic but results of the medication on individuals is not really a question at this point.
I use LLMs for writing generic, repetitive code, like scaffolding.
It's OK with boring, generic stuff. Sure it makes mistakes occasionally but usually it's a no-brainer to fix them.
Locally run, open source models, on your own hardware is the only way to really own it. Services put you at the whim of a company and I don't like the idea of handing control of parts of my stack to anyone.
The GOP appointed heads had no power. The are reports in the prior administration of political appointees having to follow legal cases on PACER because career bureaucrats weren’t accurately keeping them abreast of developments. Likewise they slow rolled rulemakings and other proceedings.

It's more in that if you improperly connect a to b someone dies, and it's not just a snap fit like a pipe. You need to do things like suture two blood vessels together, using pliers (not the technical term), inside a dark box lit up by a tube, while looking at an upside down TV image of what's going on.
Besides what others said, realistically, the effort to support N versions is not O(n). I think it's something like O(log n), because code will largely be shared between versions - you're not doing a rewrite every release.
You have to get rid of the technically literate internal competition if you want an oversight free monopoly.
And the Minsk Protocol was a thing because... wait for it... Russia invaded Ukraine. This is why it's ridiculous to blame everyone but Russia for Russia's own actions (that's what I tried to point out in my reply above).

The same way a country like the US is responsible for their invasion of Iraq, their actions in Vietnam, etc, Russia is responsible for their invasion of Ukraine. Russia invaded Ukraine, no "buts" or "ifs".

On a side note, I was trying to read that article with an open mind, but there are some red flags that I couldn't ignore. "[...] Russian officials had worked for 8 years on Minsk hammering out terms that would be agreeable to all parties [...]". Russia, as the aggressor - they invaded, occupied, armed, and even fought directly against Ukrainian forces - could never come up with terms that were agreeable to all parties. This and other things should tell you that that's not a very unbiased source.
No.

Taxes are in hindsight so you've already made whatever donations you did by the time you paid taxes.

Donations either lower your tax bill or have no effect on it. So, by not filling taxes (_and getting caught_) you're just increasing your tax bill.
Very excellent citation and explanation - one of my main attractions to drum & bass over the years has been the amazing capitalization upon dynamic range possible with modern systems. Why would I listen to Sub Focus on vinyl when the corresponding digital file (even 320 kbps - not to even mention “lossless” being somewhat possible) does not suffer from physical interface complications? I’m glad you brought up mastering and the “loudness wars” who CB is absolutely great reading for those interested in audiophile related endeavors!

"nobody will want this"
That's neither here nor there. Trump and Musk are dismantling the American government piece by piece, and I'm not terribly interested in discussing whether billionaires were the problem all along. That feels like a totally unnecessary diversion.

By all means, after America kicks out Trump, feel free to discuss billionaires and the tyranny of capitalism and everything. Just not now.
People are weirdly resistant to acknowledging the obvious implications of things if those implications seem big. There’s a broad “nothing ever happens” heuristic that people tend to mistake for wisdom.
Dallas is less expensive than LA. LA with amazing weather, little allergens, and beautiful geography. Dallas with heat and cold enough to be lethal, brutal allergens, and limited natural beauty. No one who knows better wants to live in Dallas- they have to live in Dallas because they can’t afford it elsewhere. Which works out, because Dallas has infinite land to build single family homes. When people move to Dallas they aren’t moving to Dallas; they’re moving 30 miles from the urban core. Dallas’s urban core is decaying from lack of housing - with no affordable housing for young people near the city center - downtown has become a ghost town as jobs follow the housing to the out rings. The smattering of housing that exists near downtown are apartments, very expensive town homes for the wealthy, or the original stock of single family homes from the 50s.

When I lived in downtown Dallas, I would have loved more housing. Part of the reason we left was because it was a ghost town. Very little to walk and see. At night it was desolate and unsafe.

LA has been maxed out for housing for decades. They’re constrained by geography. They can only build up, but they haven’t… only recently started loosening housing restrictions to allow for density at the state level, but even that is a half measure. They need to just swallow the pill and let density be built anywhere. Yeah, change sucks, but at least we’ll stop forcing people to move to Dallas.
It's okay. We are forced ( by our client, who has forgotten to update it's it since 2005 ) to start several clients in a pipeline. Startup is less than a minute, going from zero to a full resource group with two VMS and ancillary resources.
Great release! What is the delta to achieve that porting using a trained approach?
I try to keep "boring" code to a minimum, by finding meaningful and simple abstractions. LLMs are especially bad handling those, because they were not trained on non-standard abstractions.

Edit: most LLMs are great for spitting out some code that fulfills 90% of what you asked for. That's sometimes all you need. But we all know that the last 10% usually take the same amount of effort as the first 90%.
A large organization can usually identify groups of "similar enough" incidents to identify the correlation. (Can the numbers prove causation? Not to the standards of a scientific journal, but you can't exactly induce 100 incidents to do a controlled study.)

> 20% knowledge could be enough to fix errors yourself.

It might be, it might not. My colleagues and I are also guilty of introducing unrelated edge cases, but again, we do fine.

The case you're describing is also fairly pathological. There's nothing stopping a vibe coder from digging into their code and becoming a 20% monster like me.
We have lived in a stable system long enough for people to forget the horrors of instability. It is a certainty that a reminder is coming - what is uncertain is how far away it is.
100% - here are some of Maestro's AI-powered commands:

Main difference is that Maestro takes a reliable-by-default approach. We hear plenty of stories of folks exploring tools like the ones you mentioned, then ultimately coming back to Maestro due to reliability / reproducibility issues, which are non-negotiable when it comes to end to end testing

We at pulumi started treating some hallucinations like this as feature requests.

Sometimes an llm will hallucination a flag, or option that really makes sense - it just doesn't actually exist.
Imagine if you are already a great writer, but want to learn more about asking questions, coming up with interesting angles. Then collaborating with an AI that does the grunt work seems a natural fit. You may also want to improve editing skills rather than writing skills. By saving time and energy on not writing, editing may become something that there is more time to really get good at.

In other courses, curiosity rather than mastery may be what is relevant. So again asking questions and getting somewhat reliable answers that skepticism should be applied to could be of great benefit. Obviously, if you want to get good at something that the AI is doing, then one needs to do the work first though the AI could be a great work questioner. The current unreliability could actually be an asset for those wishing to use it to learn in partnership with, much like working with peers is helpful because they may not be right either in contrast to working with someone who has already mastered a subject. Both have their places, of course.
That I do and you’re also spot on that it does have a lot of merit as a medium - Les Paul did so much for music by lugging R2R gear around and proving its worth in the studio that his legacy is at the pinnacle of any and all people who, well, love music!
I thought my 3000 line kitchen sink function which mutates globals, uses n+1 fetching, and supports 50 feature flags was a bad idea…maybe not?

Yeah but a forecast 10 years out is a lot more fun/enlightening if it's hyperbolic. It doesn't make much food for thought to say 'We predict by 2030 the average consumer will have purchased jeans 2 sizes smaller than in 2010'.

In any case, I hope they're directionally correct. A class of widely-available drugs that lets us switch off impulses that don't suit our environment and wellbeing any more would be incredible and world-changing. I'm very curious to try GLP-1 agonists myself.
I can think of two wars over property rights.
I’m saying it’s not even a failure - negative results are still desirable outcomes of the scientific process.
I cannot think of another subject whose “101” level magical thinking has affected the real world as much as economics, though. At some point the purpose of a system is what it does, and economics 101 affects the political discourse in a way I struggle to find adequate comparisons for.
