>These reactions are psychosomatic

It's overly simplistic to treat the unreliability of witnesses as if it can only happen at one level of cognition, as implied by "psychosomatic".

What people perceive and think when they are being lied to is both complex and fundamental to a lot of experiments.

If someone reports their feelings, maybe they are interpreting what they do feel based on the false information they are given.

It doesn't necessarily mean they do feel the same as if the actual phenomenon occurred.

Suppose I was in an experiment testing acupuncture. And I am told that it should not hurt. And yet, it does hurt. That doesn't mean I necessarily report it as such. I might rationalize, not having experience with being stuck with a needle, that this is not painful - it's unpleasant, but it's something different. So I say "no, it doesn't hurt". But then, a month later, I experience a similar pain in a different context, and I say to myself "aha, this hurts the same way, and therefore that previous experience hurt".

Importantly, in this scenario, I am correctly perceiving reality at all times even though I am an unreliable reporter. The pain didn't change. I just got confused about whether it was "named" pain and whether it was "socially" pain, and whether it fit into a standard "taxonomy" of pain.

A thing that's been on HN a few times, Richard Feynman's comments on understanding rats used in experiments, comes to my mind and makes me think that scientifically minded people should respect humans for being at least as complex as lab rats.

One doesn't have to be a scientist to be self-aware as a human being.
This is how I learned of his work and became a life-long fan of both Bruno Schultz and the Brothers Quay.

What's with the indignation over this on HN? I didn't see them suggesting anyone/everyone would be able to do it, or that it was practical.

It was just a funny set of cirucmstances that allowed for an attention catching headline and a mildly amusing tale. Yeeeesh.

Caveat: the interviewer strikes me as quite flakey, but his reactions highlight how grounded Dr Cohen was.
Tcl and Tk are trailing-edge tools that are out of fashion at the moment.

Nonetheless, they have some nice qualities and capabilities. And the fact that they were designed in the 1980s/1990s means that they're relatively compact and efficient (especially compared to something like Electron.) I like Tk (and Tkinter for Python) quite a bit and find that you can build some nice and easy to use interfaces with it.

I also still enjoy the retro idea (which Apple and others seem to have abandoned) that UI elements should be visible and discoverable.
I love how tech margins are so insane we think going from 3% to 1% isn't that much, meanwhile entire industries built on the margins that fit in said gap...
I don't believe all these posts against cars are from humans, especially on this website.

I certainly believe they are from humans.

Surely, technologically savvy folks like us would have learned to appreciate why decentralized systems (like cars) are better than centralized systems (like mass transit) for their flexibility.

But many humans are easily persuaded by FUD ("climate crisis" and all that other hogwash.)
> I think it's reasonable to conclude that fair use law is indeterminant and incoherent

Logically speaking fair use would have to have some degree of indeterminance and incoherence given that there is not mathematical formula detailing specifically how much change is needed for transformation in relation to commercializing that change. Without such a formula there will always be edge cases that will look wacky in relation to everything else.
> But clearly it's not nearly as superficial as a necktie.

Not sure about that. Working without a necktie can feel like working naked. It takes some effort to change your feelings on that.
Lots of US rail infrastructure has been quietly being upgraded, and there are portions outside the north east corridor that can hit the technical minimum for high-speed rail now (125 mph).

Pacific Surfliner is one, and it boards millions per year.
This, written in later life, only briefly mentions the thing Tesla invented that was most useful. Tesla figured out how to get AC motors started. See his U.S. Patents #459,772 and #464,466. The second one shows how to use a starting capacitor, which is how AC motors are started today.

AC motors were known before Tesla, but getting them up to speed with the power source was tough. It usually required a second motor with a commutator to get the AC motor started.
Tesla figured out a simpler way, one that made AC motors simpler and cheaper than DC motors.

DC motors with commutators were easier to start and more controllable, but less reliable. Early motors had actual wire brushes, which arced, wore out, needed adjustment, and wore grooves in the commutator. Carbon brushes came later, and really good carbon/graphite brushes were not developed until well into the 20th century. It's one of those materials quality things that isn't thought about much any more, because it's a solved problem.
"Embezzlement is [...] where someone takes money or assets that were entrusted to them and uses them for a different purpose than for what they were intended." That would seem to apply just as much to spending funds on useful military equipment that's different from what they were allocated for as it does to spending them on blackjack and hookers. If the funds were being spent correctly then why would they be accounted for falsely?
Ask HN: Best way to convert PDFs to other file formats?
Some types of PDFs have always been a challenge to convert to other file formats like Word or plain text. I've had many go from perfectly formatted PDFs to useless text when converted.

Has anyone found a good converter? In the age of AI, you would think that there would be a foolproof way to do it.
Not the person you were asking, but to me, "suburban" is not defined by density, but by how walkable an area is. Even relatively low density neighborhoods can be urban under this definition as long as residential isn't zoned far away from commercial districts and everything is within a few minutes of walking or an easy bus ride. Suburban is when having a car provides an enormous QoL boost, but isn't strictly necessary. And rural is when a car is absolutely required to survive.

These are fairly car centric definitions. But considering the car enabled the suburb in the first place, I don't think it's necessarily wrong to use it as the metric.

Not surprising, the issue of extra charges for credit cards has been a recent issue in Canada.

I know the whole world is struggling with inflation and rising costs, but it feels like Canada is getting particularly screwed. Our housing prices are out of control, rents sky high, price of food way up when things like dairy are already high because of protectionism and sold by companies that have been caught price fixing things like bread, price of telecommunications a special kind of crazy, our infrastructure stretched to the limit, our roads maxed out... It's bad.

If a 4-5 hour each-way commute and 3:40 wake up times throughout an entire year of school is worth cheaper rent to a person, it's their choice.
This is not too surprising.

The most obvious way to implement something like this is to just histogram the pixels and sort by most popular, it's like literally 4 lines of Python:

# Find the n most popular colors in the array of pixels
def most_popular_colors(pixels, n):
count = {}
for i in range(len(pixels)):
count[pixels[i]] = count.get(pixels[i], 0)+1
return sorted(count.items(), key=lambda kv : kv[1], reverse=True)[:n]

This works (for some definition of "works"), but it doesn't do what users expect. They will probably complain a lot about the results.

Any image that's a photo, or uses a gradient, or has ever been JPEG or MPEG compressed, is going to have a ton of fine variations in its colors. All the pixels of "that shade of green" aren't going to be exactly #123499, some of them are going to be #133499 or #123498 or something. A simple histogram like the above code will tally all those distinct colors separately.

So you can get a most-popular list containing multiple very, very similar shades that are technically distinct integers. And you can have a color that "should" be on the most-popular list but isn't, because it's a bunch of very subtly different shades, none of which has a high enough count to crack the list.

Which means to get the behavior the users expect, a simple histogram simply won't do. You need additional logic to "bucket" similar colors together for the counting part, and then show a "representative" of the most popular buckets for the final output.

How are the buckets defined? How are the representatives selected? There are probably a dozen different reasonable implementation choices you could make. Different choices will all give slightly different (or even very different) outputs.

I would actually be very surprised to find two independently written programs would give the same output for this problem, and I would suspect they're not actually independent (i.e. they both used the same software or both found the same textbook or RFC or whatever that suggests very specific implementation choices.)
Small planes like that burn a lot of gas though which isn't cheap. You also can't nap while flying your own plane.
Gov. Greg Abbott signs electric vehicle fee into law
California NIMBYs generally consider themselves to be saving the world from overpopulation. That’s mainly an object permanence problem, but it’s true that high housing prices deter household & family formation.

There’s also the old canard about how environmentalism demands maximally convenient driving and parking because congestion and hunting for spaces causes cars to run longer.
This is exactly true, and small towns with no transit almost always have a paravan or other setup (usually it's just a minivan that can take a wheelchair and is basically a city-funded taxi).

Heck, the ridership on some extended bus lines is so bad and so expensive the city would have been much better off buying each person a small car and focusing the rest on more used lines.

What rattling is that?
I'm one of the maintainers of Bevy. In my opinion, Godot clearly has a significant lead in many fronts, some moreso than others. A clear few that are lagging behind are:

Editor: Godot has one, Bevy does not.
Animation support: Godot has support for complex animation blending and animating anything that can be serialized. Bevy does not.
Audio: Bevy's audio is pretty simple right now and lacks direct world entity driven spatial audio.
Rendering: Godot has pretty deep support for higher performance and higher fidelity rendering techniques like automatic instancing and

Everything in this list is being worked on, but require time to bake. Everything else more or less has most of the core pieces in place that Godot has, though may be missing a few small features here or there.

Where is Bevy ahead?

Multithreaded CPU performance. I can almost guarantee your average Bevy app will have higher thread utilization than your average Godot/Unity/Unreal game, and this will continue to scale as more complex computations are required for various engine systems are added.

Testability: ECS makes it really easy to write dependency injection based unit tests, something otherwise difficult to test end-to-end with engines like Godot and Unity.

Extendability and customization: Bevy is plugins all the way down. Godot definitely takes a much more monolithic approach to building an engine, and making significant changes to the core engine will require forking. Where Godot requires exposing deeper APIs for exposing functionality, Bevy already supports ripping out the relevant plugins and subsituting just those with your own.

Memory safety: As the mantra goes, every 1k LoC of C/C++, there's one CVE that is yet to be found, and 70% of those are memory safety issues. Bevy heavily leverages unsafe in the ECS, but rarely touches it in the other core engine crates. We can with high confidence say there are no memory safety problems or problems caused by undefined behavior in Bevy due to Rust's strong safety guarantees.
> I mean PA semi was purchased in 2008 and the first A4 processor was 2010, the writing was already on the wall a good decade out.

Is this similar to how AMD's Bulldozer architecture back around that timeframe was the writing was on the wall for their current competitive dominance over Intel?

PA Semi was a great talent accu-hire, but AFAIK at the time of acquisition they only had Power-based designs ready for market.

> It kind of feels like Steve picked the last of the low hanging fruit and then bowed out before it came to stagnation.

PT Barnum was a renowned showman as well, but that doesn't mean he trained all the elephants.

For instance, I would hardly say the release of a market-dominating phone was a foregone conclusion based on the success of the iPod, and an Apple without the iPhone would look incredibly different.

Sure, people wanted to take their music with them, but the nearly purely multitouch interface was a fresh invention - the iPod did not have a touch interface AFAIK until three years later.

I just don't see something which was such a fresh take and new engineering - to the point that other smartphone vendors thought the original keynote demos were staged - was low-hanging fruit.
I think some people on here default to a highly comparative/competitive mindset. When they see titles like the one here, they assume there's a subline reading And because I found this hack and executed on it, I'm more resourceful, capable, and smarter than you, and if you can't keep up with me its your fault if you don't succeed

Not saying everyone here thinks it but the emotional reaction to these kinds of things makes it seem this is how it feels to some people.
This story reminded me of a story I heard in 2017, during a cocktail party.

Some entrepreneur had worked out a lease for living space, in the commercial heart of a large urban city....living in what during daytime is *literally* some VC office. He would come in at 8pm+ when the VC staff had left, and leave in the AM to work. And he paid a ridiculous low amount of rent to have what was effectively a 25K lease at market price.

Not sure what exactly was the motivation for the VC to agree to this (imagine having a bed in your office?) but , wondering if there is an underground network for this that im not aware of?
You realize you can subscribe within the app right?
> Credit card rewards are a regressive tax on the poor

Maybe credit card loyalty systems are specifically, but if you want to make comments about the entire system of credit cards then you should look at the entire system of credit cards to figure out who’s subsidising who. On the other side of credit card rewards the fact that revenue from high spenders subsidises credit account defaults. If you chose to only focus on that single element of the system you could just as reasonably say that credit cards are a progressive tax on the rich.
It's not that Apple is disinterested in WebKit now or just doesn't want to spend money on it. They intentionally want to keep it bad, so that Web apps won't be a viable alternative to native apps on iOS.
>it's a bit as if I were able to claim a salary for my dead relatives because, you know, I used to live off of that

That's just me.
For the most part people didn't ride horses to get around town (despite what Westerns depict). Horses were mostly used to pull carts moving goods around like trucks do today. The average city dweller walked or rode trams.
I lived in Copenhagen’s suburbs, Østerbro, for several years and the public transit—trains and buses with the occasional taxi—were finely grained enough schedule-wise for me to easily work as an appointment-based professional (video/film editing, compositing and FX). I LOVED not having to deal with a car.

I now live in the Seattle suburbs, Redmond — very close to the same distance from the work site as in Copenhagen — and there is no way I could realistically rely on public transit to hit appointments unless I left an hour or two early—and, in bad weather, many hours early. I can’t imagine doing what I do without a car.
It’s a great way to filter out the people that won’t listen to what the boss says.
> I'm sure you can come up with the perfect counterpoint to my anecdote.

Even if your interlocutor can, and even if the large scale studies run counter to your argument, that doesn't mean your experience is invalid.

Life isn't a double-blind randomised placebo-controlled study. There is no control group consisting of you and your cohort to measure against.

The scientific method is, I argue, on the whole, the wrong instrument to bear in these scenarios, at least because measuring the metrics affects the study group and publishing the resulted affects the society in which the study occurred.
Yep, and 19th century American cities tend to have very wide streets due to horseshit. This is often misattributed to cars.

Ask HN: Is Moore's Law over, or not?
Every once in a while I see an article that seems to claim that Moore's Law is over, or slowing down, or about to be over. Then I see some counter-claim, that no, if you account for added cores, or GPUs, or some other third thing, that actually it's still right on track. This cycle has repeated every year for like the past 10 years, but the last few years feel like things have really started to slow down. Maybe that was partially illusory with the chip slowdown from the pandemic, but I figure now that we're several years out we should be able to say for sure.

It also seems like a pretty important question to answer because it has big implications for the advancement of AI technology which has everyone so freaked out.

So what's the consensus around here? Is Moore's Law actually over yet, or not?

At work I also used to stare at a lot of graphs to figure out bugs. We reuse some of the graphs so we've gone through the effort of recording node positions in metadata and given the graphs a UI where people can drag nodes around and re-save. But it's clunky.

I always wished I could invent some domain-specific heuristics to lay out the graph automatically but never took the time to.

Manually moving nodes actually worked fairly well for our use case, but it made a mess of text diffs when e.g. nodes were inserted and the position of all subsequent nodes shifted, so as a consequence we had to invent ways to visually diff graphs. Maybe the improved automatic layout would have been easier after all.
Fellow IMSA alum here, also underage (skipped 3 grades). I'll cosign most of what atdrummond says here, but shift emphasis: to me and the majority of my friends (many of whom I'm still in regular contact with 30 years later), it was specifically being around other kids like us that was a godsend. The diversity was also broader than at most of our previous schools. The academics were an important part of it (not least to justify the state funding) but the unique value for a lot of us came from the nonacademic parts.

Re the OP, I wonder what's next for him. I know that college was a little weird but manageable as a freshman at 15; a junior at 12 is going to have an even more different experience (and then... grad school at 14?) But if he's motivated and it's not just his parents driving this, he'll come up with something and do fine, I'm sure.
I would say that you'd be hard pressed to find a city of any moderate size where it was not possible. Some would be better than others, but it's possible nearly everywhere.
