I wouldn't consider a Lutron light switch to be a direct comparison to Crestron. Crestron targets the ultra wealthy by being very reliable (assuming setup by a competent programmer) with unified control of pretty much everything household - shades, lights, audio, video, etc. They're aiming for the kind of people who will pay a premium to make sure their house just works, every time, without having to deal with tech issues.

You could certainly bodge together a similar system for less money, but the controls won't be as nice and it'll be nowhere near as hassle free long term. HomeAssistant and competitors have really been catching up in the past few years though, i'm excited to see competition in the market. I wish they could all play nice together with reasonable APIs :/

From a sibling comment, it seems that using second-order logic resolves this. I'm comfortable saying that if you want to stick to first-order logic then you can say that BB(748) has different values depending on the model in some sense, but that the "real" BB function is defined using what we normally think of as the counting numbers as you'd define with second-order logic, and that's the value that's actually correct.

> But I see it as a kind of craftsmanship and sharpening my own tools. I don't know another, better way to do that.

Toooootalllly. This project started out for me as a learning exercise, and for a long time an explicit non-goal of the project was to ship a game. It's just my own little land that I know every nook and cranny of for experimenting and, sharpening my tools, as it were. It's also the best way I've ever found.

I scraped HN's 1000 most mentioned books and visualised them. This month I used a new embedding model (Nomic), switch out UMAP for PaCMAP, and added automatic cluster labelling.

The clustering and dimensionality reduction aren't quite as stable as I'd like, but most seeds give decent results now.

Explain to me what tasks can be solved in the approach with flows? I used Node-Red in some automation processes. I managed to solve only simple problems that are easy to solve without AI. But how do you program in this style? What does the flow style look like, for example, a program to find the shortest solution of a sokoban or game 15?

PS. Usually, when I need to make all photos in the folder black and white, I use imagemagick.

> No you were pretending that it couldn't be done. You specifically said earlier people were too stupid to learn because many people couldn't tie up their shoelaces.

This remains entirely true. That's part of why it's tough, expensive, and time consuming. People do dumb things. Much of safety is figuring out ways to lessen opportunities to do so, and mitigating damage when they manage it.

See, for example, aviation/medical safety, which take the approach that individuals making mistakes is an indictment of the system that permitted that mistake to occur. We engineer them away, as much as possible, with pretty great success overall.

> I knew that. I thought I deliberately misinterpret the sentence so you would be forced to clarify. You did to me several times in the other thread.

No, I still wanna know how you stop time between checking behind your car and getting in, starting it up, and backing out, so no kid/pet/whatever can run behind it in those 10-15 seconds.

As with most international law, the two most likely originations are either (a) mutual self-interest (e.g. chemical weapons) or (b) horrendous and inhumane abuse.

I expect with the first first-world drone war on a third-world country, there might be pressure at the UN to put something in place. At least for the automating genocide case.

>there are analoges for most of the hybrid components in a pure-ICE car.

The error in this is in assuming the analogs have equivalent reliability or cost in each system.* (The original point is about cost of ownership). They don’t. So, while both have batteries, the reliability and cost of each is very different. Same with the ICE component etc. My issue is broad generalizations about reliability without speaking to the nuance.

I’m not set against the idea of a hybrid being more reliable or cheaper, but more against the superficial generalization.

* also the analogs miss some of the complexity. Yes, both have a battery, but a hybrid requires high voltage and auxiliary batteries, meaning the battery system is by definition more complex.
by lowbloodsugar | 2025-06-30 16:47:58+00:00
No starter and no alternator? Hybrids don’t have an electric motor or a way to turn mechanical power into electrical power? Also they don’t have timing belts?

I’m not super convinced that accessory belts are a major cause of maintenance. I only recall having to do that once at around 120k miles.

I think there is a good argument to be made that implementations like Toyotas HSD are more reliable than plain ICE, but you’re not making it here.

So basically you're saying that if I want to add mathematical expressions to my JIT'ed code I should obfuscate the purpose by writing multi-line operations to build them instead of having the ability to plonk it in more or less verbatim?

As I said, I fully agree that operator overloading is horribly overused but the purpose of this JIT is to quickly create JIT code with customized expressions then those expressions should be possible to write fairly verbatim instead of following something with a religious zeal (is even matrix multiplication allowed to overload?).

And yes, AST's usually contain a lot more information such as source-location,etc for debugging (here it'd be interesting if an operator overload is able to take C++20 source_location as default parameters), but again this is for a specialized jit.

As for passing more options to mul nodes, a mul node is just that and nothing more (only extra interesting data in a restricted scenario as this would possibly be source_location as noted above).

> less expensive, cars have been

> knocked off - the Rio,

> the Prius C, the Fiesta..

You are incorrect. Prius C in 2005 was $21,510 (not really "less expensive") and that is about $34,827.67 in 2025. (See: https://www.kbb.com/toyota/prius/2005/)

And in 2025 Prius starts from $28,350 (see: https://www.toyota.com/prius/)

So this narrative that there are no more cheap cars is incorrect.

I’ve known people who claim up one side and down the other that Advil is more effective than generic ibuprofen and it’s thought to be down to the other ingredients. I had at one point convinced myself of this as well, but these days even Advil doesn’t always help. Bummer is that only a couple of CBD products do anything for me either. May be why I’m so grumpy.

They actually receive some of the highest subsidies of any companies in the US.

Some examples include:

* Politicians often give automakers often receive state and local tax breaks in exchange for constructing plants in their jurisdictions

* Federal grants and incentives for clean energy initiatives

* The infamous 2008 bailouts, where for example, the US Treasury bought enough GM shares that they became the controlling shareholder, effectively nationalizing the automaker.

> Honestly, the pervasiveness of LLMs looks to really erode the critical thinking of entire future generations.

Yes and no.

Upper middle class parents as a group will still instill critical thinking skills in their kids.

But the above comment reveals more about SES (socioeconomic status) and education in general rather than something specific to critical thinking or LLMs. The current education environment in the US heavily favors kids from higher SES families for a number of reason. LLMs won’t change this.

The challenge for the education system, imho, is to find a way for lower SES kids to thrive in an LLM environment. Pre-LLM, this was already a challenge, but was possible. Post-LLM, the LLM crutch may be too easy for some lower SES folks to lean on such that they don’t develop the skills they need to develop higher order skills.

You’re right, tariffs aren’t subsidies. They just function like one by kneecapping foreign competition so domestic automakers can overcharge with a straight face.

Actual subsidies? -Federal: ATVM loans (e.g., Tesla, Ford), $7.5K EV tax credits.

-State: Georgia gave Rivian $1.5B. Tennessee handed VW ~$500M. Michigan’s tossed cash at GM like it’s confetti.

So yeah, no subsidies at all, just billions in “non-subsidy” market distortion to keep the hometown heroes afloat.

So, can you provide any substance to the conversation?

There's a lot of potential for desktop rapid-prototyping with electronics. I think one of the things that is killing us is the tooling. One of the reasons I started building an autorouter was because I wanted to be able to have different "build targets"- e.g. a build target that is a PCB with no vias and only 0 ohm resistors (jumpers). If our EDA tooling supported different build outputs, then we could have earlier prototypes built with less-than-ideal equipment (e.g. conductive 3D printed filament, as the article suggests)

We were discussing this in a different thread and apparently the studies surrounding that approach did not account for confounding factors at all (alcohol use, stable couple and so on), so the data is not as reliable.

Also forgive my skepticism, there is no money to be made for the contraceptive industry, so of course they will not finance it (unless they sell diapers too).
by tharmas | 2025-06-30 16:50:44+00:00
Which is why, when the rich buy up assets (ie land), its inflationary. They are not adding to the pool of assets (supply), they are consuming them. Sure, I understand, land can be "developed" so that it can become useful (eg draining a swamp, building a high-rise instead of single storey) so in effect that is adding to the supply. But as your History teacher pointed out land is still effectively a fixed supply.

It would be nice if govt policy could help create the conditions such that a return on investments in production where more attractive (ie profitable) than buying up a fixed supply of assets. But instead govt policy did effectively the opposite.

Henry George and his LVT (Land Value Tax) comes to mind.

I am unqualified to answer but ran this question through an AI.

The rough number is that apparently 10% of CO2 equivalent comes from meat farming, but don’t trust this.

What did surprise me though is that a much larger benefit would result from repurposing the feed stock and grazing land, together comprising ~25% of the earths habitable land. Land and ecosystem restoration would likely result in feedback loops in the opposite direction.

I have a friend in Denmark that used to run a small carbon neutral farm, where the carbon offsets were all generated by other activities on his land. His all in cost for a kilo of pork was 700kr, or over $100 dollars. Meanwhile, you can but a kilo of port at a supermarket for ~$20. He could only sustain this because he ran a farm restaurant selling the best burgers in town, and even these were probably a loss leader for his best-in-town fries and mayonnaise making up the difference.

It's standardizing the contract between the programmer and the compiler.

Previously a lot of C code was non-portable because it relied on behaviour that wasn't defined as part of the standard. If you compiled it with the wrong compiler or the wrong flags you might get miscompilations.

The provenance memory model draws a line in the sand and says "all C code on this side of the line should behave in this well defined way". Any optimizations implemented by compiler authors which would miscompile code on that side of the line would need to be disabled.

Assuming the authors of the model have done a good job, the impact on compiler optimizations should be minimized whilst making as much existing C code fall on the "right" side of the line as possible.

For new C code it provides programmers a way to write useful code that is also portable, since we now have a line that we can all hopefully agree on.
by jerf | 2025-06-30 16:50:53+00:00
You can almost simplify it to simply observing that PREMATURE optimization is not the same as OPTIMIZATION.

Most people I see who get offended are reacting to the claim that optimization is never useful. But it's pretty easy to knock that claim over.

I don't deny that plenty of people use adjectives very sloppily, and that much writing is improved by just ignoring them, but Knuth is not one of them.

Hardly a strange take IMO.

We've (the west) effectively encouraged this sort of behavior. OUTSOURCE IT ALL TO CHINA! Our corporations and shareholders have most certainly reaped the benefits from this. Our politicians have made a lot of money this way, too. Lots of people have deliberately turned a blind eye to this sort of behavior and didn't think about the long term ramifications of pushing everything to be built in China.

Call it cartel like behavior, fine.

China is merely playing the hand it has been dealt and looking out for itself and the survival of its economy and political apparatus. Trade is one way to do so, another is technological progress.

We've subsidized capitalists taking the risk to develop this tech. China has bypassed the ownership class and gone straight to the manufacturers. Some of those capitalists have enriched themselves when they should have passed those costs off to make their products cheaper to stay competitive - that's the whole point of subsidies. Instead, one of those capitalists chose to instead take the subsidies, keep his cars expensive, and make himself the wealthiest person on earth.

Don't hate the player, hate the game.

I don't think maximization of shareholder value is really the interesting part, it's the mandate that they must be prioritized ahead of employees and customers.

> It's that if you're going to make a decision that affects 1/3 of the companies value you need to actually claim it's in the shareholders interest that you do so.

I'm not really sure where the 1/3rd ratio came from. Can you explain? To my layman's ear, "value" and "shareholder value" are the exact same thing.

Most of the important ones I took had:

1) Written in person exams that were most of the grade (this includes "blue book" exams where you have to sit in front of the professor and write an essay on whatever topic he writes on the board that morning as well as your typical math/algorithms tests on paper.)

2) Written homework where you have to essentially have a satisfactory discussion on the topic (no word range, you get graded on creative interpretation of the course subject matter.)

Language models could maybe help you with 2 but will actually kill your ability to handle 1 if you're cheating on homework with them. If anything language models will mean the end of those retarded make-work cookie cutter graded homework assignments that got in the way of actually studying and learning.

One interesting lesson is to see the effort involved in acquiring new customers and setting up funnels, especially when bootstrapping with a small budget. Sometimes, as developers, we are in our bubbles and don't realize how much skill one needs to figure out the customer acquisition domain.

>However even in 2012 (when Go 1.0 was released), errors as values was a pretty novel idea among mainstream programming languages

>Errors as values is a quite old idea, predating exceptions, mainstream just got a bit forgotten about how we used to code until early 2000's.

I'm not sure these two sentences are in disagreement with each other.

>the beauty of 3rd party dependencies is that each dev has a different opinion what they should be,

The hope is in that some time in the future, the community will eventually coalesce on a superior option with the appropriate patterns. Because the mainstream had forgotten how to use errors as values, my point is, its more likely that Rust 1.0 would have baked in a poor solution.

To be fair, it likely will not be a dark age.

The reality is that our companies will still be able to hire scientists from foreign universities. There's still Tsinghua. The Germans rolled deep at a Harvard get together I was at and nearly all of them were from TUM or Mannheim. And the brightest was actually out of Ludwig Maximillian.

So humanity's capacity to push the boundaries of science forward is safe with or without us. Now, do we want to be a part of the leading edge of that? My answer would be an enthusiastic yes! But it's perfectly right for other people to feel differently.

I built UniLinkPay after getting tired of sending multiple payment links to different clients. Some use PayPal, some prefer Stripe, Zelle, Venmo — it’s messy.

UniLinkPay creates one clean, shareable block where you can list up to 7 global payment methods. No login required. No signup for payers. Just send one link and get paid.

In the city where I live, the contrast is striking: the local state college boasts dorms and facilities that are remarkably luxurious—architecturally grand, stylish, and visibly well-funded. Meanwhile, the local NVIDIA office operates out of a building that looks decidedly unremarkable, even shabby by comparison. One is supported in part by public funds; the other is a profit-driven enterprise.

I absolutely believe in the value of academia and agree we should support it. But this administration has made it clear that reform is expected. I’m not convinced that message is being fully heard. Until we see meaningful changes—such as a leaner administrative structure and a shift away from spending on vanity infrastructure—I’ll pass.

No, this is an orthogonal effort.

We have two channels for distributing software in Ubuntu: the archive and the snap store. Each are suited to different scenarios.

Irrespective of any view on Snap as a packaging format, the workflow and developer experience is, in my opinion, much simpler to work with. The barrier to contribution is much lower.

The work on debcraft is to try and bring some of the lessons we've learned there to those developers working with debs - while also introducing new primitives that will allow for extended integration testing of the distribution using some of our existing (well tested) machinery.

Exactly. The study has been set up to produce this exact result. They essentially limited the human doctors to bare essentials, on specialist cases(!), while providing the LLMs with all sorts of help, including discussion among several AIs.

That's like letting one group of students have a strict closed-book exam, while another group can take the test as a group exercise and accessing any material they like, then claiming that closed-book exams lead to worse outcomes.

In a nutshell the study is just slop designed to get attention. The headline result is what they really want people to hear, and that's all the media will be repeating.

>your math would that for the pure ICE would be R(gas ICE) * R(traditional transmission).

No, that was already baked in. I purposefully linked the R(gas ICE) = R(hybrid batteries). Note they were both dropped out of their respective calculation. Just like a hybrid isn’t going to go very far without batteries, but you left that reliability out of your hybrid equation. It seems you’re more interested in arguing that reading posts in good faith, so I don’t think it’s productive to continue the discussion.

The rhetoric - both from those starting DEI intiatives in the last few years and from the reactionaries acts as if it's world changing. But 99% of DEI is BS like rainbow branding or 1hr click through trainings.

I'm in industry, academia is similarly standing up for industry all the time, in addition to feeding us all the basic science that we turn into products.

Academic labs are often very eager to partner with industry to bring things to market. At least from my view in cancer. Especially the NCI is very impactful in making sure that discovery makes it to patients as quickly as possible.
