AI is going to increase the value of prestige education over middle-of-the-road education.

Middle of the road colleges will not have the resources to ensure that students learn despite AI, whereas the Oxbridges, etc, will retain their tutorial systems and smaller class sizes, where AI is of no use whatsoever.

A comparable phenomenon perhaps exists in the news publishing world. It was envisaged that easy access to information would be the death of pay-to-read news. However, the huge volumes of mediocre and politically-driven output that swamped the internet, airwaves, and printing presses instead increased the relative value of thoughtful and well-sourced new and writing, e.g. the FT, Guardian, BBC, etc., even the New Yorker...

> and behind our back file rewrites remapping imports.

I've been bitten/misled by that so many times. How hard is it to just $(find -exec sed) to patch up the imports if you fork a project, versus later finding out oh, so that's why line 50 of some random dep doesn't at all do what it says in the repo

If I was Go Dictator For Life I'd make the compiler issue a warning for any replace statement in go.mod

> Are those people "capital" or not?

Probably not. In the sense it's being used in this discussion, capital are people whose majority of income comes from dividends and rents. So your typical 401k (likely - I am not American) isn't in that category, rather they are labor with some savings for an old age.

The main difference is whether you need to work for someone or not. That determines your social class and to a large extent, self-interests.

They have not been exaggerated and they have not improved (well, nothing outside standard, keeping up with inflation, type improvement)

The JVM ecosystem has given up on jit warm up time for hotspot. There are other solutions like graal.

Whenever I have to deal with Java projects I'm always astonished at how completely "normal" a 4 minute startup time for a REST endpoint project on a single core machine.

The only part needed to make an AC condensing unit a heat pump is a reversing valve (which can change coolant flow direction based on thermostat input). The cost for this valve is $100-$300. There is no reason to not make every unit a heat pump by default, considering the minimal cost and that you're amortizing the cost of the system over 10-20 years.

With that said, depending on your latitude and climate, non electric backup heat might be necessary (to your point, a fossil gas furnace). Depends on your home envelope thermal efficiency (how long can it maintain heat without additional input or solely with solar input during the day), electrical utility reliability, etc.

That confusion is unfortunate, thanks for checking the books!

Am now a bit curious as to what the country/scientific field table with most common log notation would look like as it seems there is indeed a lot of variance...

> The United States Department of Commerce recommends that the notation lnx be used in this way to refer to the natural logarithm (Taylor 1995, p. 33).

> Unfortunately, mathematicians in the United States commonly use the symbol logx to refer to the natural logarithm, as does TraditionalForm typesetting in the Wolfram Language

I was wondering if this was going to happen after we saw the iPad with the M chip in it.

But this does make me wonder, how much of a difference is there really between the A chips and the M chips. Clearly they are similar enough if either can run iPadOS or Mac. Or is this a case of the operating systems having shared components that make this easier?

But then it does beg the question, why have the distinction in the first place if they are going to use the chips in other hardware. Originally I thought the distinction was that the M series was meant to not give the impression that the Mac line was "underpowered" running mobile chips like on the iPhone.

Essays like this filled with AI-generated spew are really irritating. I hope these figures aren't hallucinations, but it jives with my own experience:

Ductless systems averaged around $29,000, but quotes ranged from under $20,000 to over $40,000. Ducted systems averaged $38,000, with bids spanning from under $25,000 to over $50,000—an astonishing 100% difference from low to high for both systems.

This is a non-starter for tens of millions of households. Not just the range, but the low end of the range, which approaches the cost of a new car. Lots of people will look at this, and say, "No thanks, I can get 2 or 3 window-mounted ACs at Walmart for a fraction of the price."

Four years ago when we got a heat pump/mini split the cost was at the low end of the range, but sweetened with a state loan program with 0% interest for the life of the loan. No brainer. I doubt those incentives exist in the current rate environment.

The primary factor that correlates with reverse cameras reducing backup accidents is age - people over 70 have higher backup accidents rates without cameras/sensors. FTA:

> When averaged between the 2 automakers, effects were significantly larger for drivers 70 and older (38% reduction) than for drivers younger than 70 (1% increase); effects were significant for older but not younger drivers.

A big SUV is probably an exacerbating factor, though.

Also, for any kind of car, rear cameras and sensors decrease impacts while parallel parking. I see far fewer damaged bumpers on newer cars these days.

> Why shouldn’t it be possible for people to lose their jobs?

This is a strawman argument that seems made in bad faith, but I'll bite anyway: I am not saying that no single bad idea or mistake should result in the loss of a job. I am saying that most of the time such a response would be an extreme reaction, especially when directed at the lower-level source of the ideas vs. the more senior accountable parties who are paid to know better.

Magnitude matters, as does accountability. Creating this world of extremes where one mistake of poor idea leads to termination is a pretty quick way to a toxic and non-productive work environment. Enact accountability where it sits, not across the entire chain.

One important thing to note is that everyone has an agenda.

Days ago someone wanted to convince me that AI is already outcompeting humans on a broad scale. Yet I go back to ChatGPT and it gives me non-stop hallucinations.

So I can only assume that the person is either incompetent and that's why they personally feel that AI is better. Or they already internalized the AI hype so much because they're the ones selling it.

You should try PlatformIO. It solves exactly the problem (last line) for known boards. I did some hobby work but your mileage might vary. Caution that it is C++ first platform (rather than C), so if you are having allergic reaction* might try some other toolkits.

*Given you initially chose Rust for this, I would have tagged you as someone who is into vibes/feeling good rather than getting things done, and the suggestion would have been wasted on you, but you seem to have learned your lesson so rather than dismiss C++ out of hand, take a look.

That's the geopolitical advantage of being the world's manufacturing hub.

Foresight is required when dealing with such entities, not hindsight.

If my electric car comes in at 1/4th the price of an American built one, so be it. The tradeoff here is that in countries that aren't engulfed by rent-seeking capitalists who only answer to themselves, countries like China have a policy goal and will make sure the state utilizes the private sector to meet the goal.

For example, Mr. Musk could easily take some of that $450 billion net worth of his and make his cars considerably cheaper. He has taken enormous subsidies and kept his cars expensive. In China, the state would not let someone with that amount of capital take subsidies, and most certainly wouldn't allow them to bribe the government with the government's money.

They have been mandating that in most UK countries for decades and it is definitely one of the reasons why roads are safer now.

Yes, that’s why I put deliberately put “series” in my original post.

The math is clear: in series, the system reliability cannot be greater than any single part.

So if the claim is that hybrids are more reliable than ICE, there needs to be some sort of discussion about why you think the ICE is more reliable. You keep bringing up transmissions when the main point is related to the ICE.

The study seems to be incredibly flawed.

> Women with active sun exposure habits were mainly at a lower risk of cardiovascular disease (CVD) and noncancer/non-CVD death

Not surprised there because people who spend more time outdoors will typically be participating in physical activity at the same time, while people who avoid sun exposure will typically be seated while participating in sedentary activities.

If we want to see if sun exposure is the sole reason for longevity, we will have to force the subjects to sit on a couch outside.

Claiming that not getting sunlight is the same as smoking is pure garbage.

I think you and I are saying the same thing honestly.

The parent seems to be of the mind that it's never a viable option for someone to lose their jobs for something; which I find an extreme position in itself.

I'm not sure how this context is lost, as precisely this point is what I'm getting at. I'm not jumping to extremes as some imply (including you), I'm saying it should be on the table for the most hopeless egregious offences.
Show HN: Heap – save full-page local archives of webpages with just one click
by busymom0 | 2025-06-30 15:32:06+00:00
Heap is a macOS app for creating full-page local offline archives of webpages in various formats with a single click.

It's a menubar only app and a single right-click creates full-sized image screenshot, PDF, Markdown, HTML, and WebArchive. It can also be configured to archive videos, zip files etc using AppleScript.

You can archive multiple links too by dragging and dropping a text string or text file containing the links.

It can do things like run JavaScript on the website before archiving, signing in with user accounts before archiving, and running an Apple Shortcut post archiving.

You can configure the directory where the archives are stored locally. So, this way, it can sync the archive directory with your other devices automatically via iCloud/Google Drive/Dropbox etc.

It also provides single-click way to access archives of the front most browser link on the Wayback Machine (archive.org) or Archive.today.

I feel like people who are into data hoarding and self host would find this very helpful.

Heap's free version has all the features available except it puts a watermark in the archive which can be removed with a one-time-only in app purchase. I am also the developer of HACK (hacker news app for iOS, macOS and Android) and have a reputation for not using ads, tracking, analytics, or subscriptions.

Please try and feel free to ask me anything:

The replies to this made me think harder about pyramid schemes vs population pyramids.

I concluded it is in fact OK to bring in young working people from elsewhere to fund the retirement and social services of those already here and ageing. I was thinking there would be a problem as those immigrants in turn aged and switched from net contributors to net claimants, but I hadn't taken into account that they like all of us die off as they age: indeed, what makes the pyramid a pyramid.

Spoken like someone who hasn't owned a late model car.

>I can put it one that is better than the factory one for a cheaper price

As someone who used to be involved in the car audio competition scene, those days are long gone. Modern sounds systems are great, and tightly integrated into the A/V system.

>the sensor that tells you if you have a flat tire

The sensor will tell you when there's a rapid drop in pressure. You won't notice the flat until you're near driving on the rim.

>the emergency call button (while everyone has a mobile phone these days), automatic regulating seats (pulling a lever is too much difficult), dual zone clima control (it's the same space in the same car, why I would want to set 2 different temperatures?)

Old man yells at great features.

>they no longer provide you with a spare tire, just an useless repair kit...

Yeah, they provide roadside assistance. Because changing your tire on the side of the road is dangerous (as is driving on the donut).

Plenty of used jalopies out there for you.

Main article about the rumors of a low-cost Macbook here [0], this is a related article confirming that recent code supports the existence of said MacBook.

Apple has long sought to get back into the education market is once ruled before it was decimated by the launch of the Chromebook. A low-cost, plastic Macbook with stripped down features only available to the EDU market wouldn't be a bad play. They made EDU-only models before (sold the white Macbook long after it left general availability), and the A18 Pro chip has similar single-core performance to the M4 so if they can get the rest of the cost down it might be a hit.

> When we say Chinese government subsides, we are not talking about tax reductions or interest free business loans, we are talking about the Chinese government itself operating the business and selling the products at a steep loss in order to undercut and wipe out incumbent global competition in the world market so that China becomes the primary worldwide supplier of those particular goods.

Where did you get that information? There were previous investigations by the EU Commission about Chinese government subsides, and "tax reductions or interest-free business loans" were the main allegations.

I'm still in the "learning Rust and discovering crypto" phase.

As I have a web+mobile background, I'll probably start with some simple mobile or web apps, a wallet, price alerts, seed phrase gen, ens explorer, etc, basically anything that's crypto / defi / blockchain adjacent to understand the field better and ease into it.

Then, I'll also build stuff from the ground up (build your own blockchain, smart contracts, etc) so that I have a deeper understanding of the basics, not just "hand-wavy" ideas like "freedom, sovereignty, decentralized, store of value, trustless, permissionless", etc.

In parallel, I also plan to do non-crypto stuff to practice Rust and to have an escape route to web Rust in case I don't like crypto all that much or can't get a job right away due to lack of Rust + crypto experience..

Then, I hope, as I have a better understanding of the field, I'll have more interesting project ideas, too.

We've done similar things when it comes to military and military-adjacent technology.

If a government believes in the potential and promise of a given technology and wants to dominate in that sector, it should be allowed to. That's the premise of worldwide capitalism and markets. Capital is allocated to where the owners of said capital wish to allocate it to, and that's the free market at work.

Is it an unfair advantage? Define "fair".

I think it is to do with the targeted/campaign attacks. Ordinary spread of viruses in some rar files are generic enough. Otherwise if you are an outfit working from CIS countries it is just a logical due diligence not to become a target of their internal security people. For instance if you create a botnet and rent it, then some other group might do proper damage using it; it is safer to just host it outside.

There are some advantages to constraining our runaway pointers to the part of the language written under the `unsafe` package, as opposed to doing the whole thing in C where we get the advantages of no language preconceptions of garbage collection getting in the way but the disadvantages of forever having to wonder whether we have vulnerabilities in the bog-standard steps like "reading from the input file."
LyteNyte Grid: A React Data Table That Doesn't Break at Scale (1M Row Demo)
by roarlyte | 2025-06-30 15:34:08+00:00
LyteNyte Grid isn’t just a high-performance React data grid. It’s the data grid that stares down a million rows and says, “That, all you got?” We pushed a one-million-row demo on GitHub like it was an ordinary Sunday.

No performance issues, no developer dread (for the grid, anyway, your codebase might still cry). And the real kicker? It could scale to 10 million rows. Maybe we’ll do that next.

interest rates are controlled by central bankers, not magic. they make decisions based on their analysis of the economy. they raised rates to slow down the rate of investment and to suppress wages, in order to get inflation under control. Less money in circulation means reduced demand means prices stay lower, meaning lower inflation. that's the theory anyway, and the explictly expressed reason for raising rates by central banks. there's no mystery about it.

> I still don't understand the urge in the US to own a Truck at any cost

Prior to the pandemic's impact on prices, trucks generally offered better TCO. I struggle to imagine that still holds true in the current landscape, but the shift has happened recently enough that we don't really have a good picture of what the total cost is over a sufficiently long period in light of how the world has changed.

So, right now, amid many unknowns, people are gambling on the past being indicative of the future. They might get burned hard, or they might come out smiling in the end. Time will tell. When it does, and assuming it shows that the TCO benefit is no longer there, you will start to see movement away from them. People aren't completely irrational – but they are slow.

Yeah, it's one of my favourites as well. And it weirds me out that the "premature optimization" bit is the most quoted piece of that paper — arguably, that's the least interesting part of it, compared to the musings on the language design and (semi)automatic transformation of algorithms!

I personally find that "break/continue" with (optionally labelled) loops cover about 95% of GOTO's use cases today (including "one-and-a-half" loops), although e.g. Rust and Zig, with their expression-oriented design (and support for sum types) offer an option to experiment with Zahn's event mechanism... but usually factoring an inner loop body into a separate function is a more clear-to-read approach (as for efficiency? Hopefully you have a decent inliner idk).

The only thing I truly miss, occasionally, is a way to concisely write an one-and-a-half range/FOR loop. Something like this:

for key, value in enumerate(obj): emit(f'{key}={value}') between: emit(',')

When you have a generic "while True:" loop, conditional "break" works fine enough, but here? Ugh.

The design of a powersplit hybrid (like a Prius) allows for consolidation and elimination of a number of common failure items on a traditional ICE vehicle.

- pure ICE needs mechanical gears or a belt-style CVT. a HV power source and 2 electric motors enable the use of a dead simple planetary gear set to change the ratio between ICE and the wheels.

- ICE needs a starter and an alternator. psd hybrids use the existing electric motors and a dc-dc converter to do those jobs

- belt powered components (e.g. A/C, power steering) are replaced by more reliable electric versions powered by the high voltage battery

- ICE needs small displacement, high compression, turbo'd engines to meet power and efficiency targets. Hybrids can get away with wheezy but efficient and reliable low-compression engines because the electric motors make performance acceptable

- ICE cars need to run their engine anytime they are moving. Hybrids will have 20+% lower runtime and that runtime will be spent at optimal RPMs and with minimal stress as bursts in acceleration are assisted by the electric motor.

Which is easier, installing them in new vehicles, or making a billion drivers undertake remedial training in basic safety?
