Hong Kong was always going to be over.

In the days before about 2000, Hong Kong was special case in that it was one of very few gateways into China. It was small and cramped, not a great place for living or business. After 2000, it became just one of the smaller, less modern, Chinese cities on the southern Chinese coast. It didn't have any special advantages over the next city.

Only a hundred kilometres or so away are two larger, much more modern Chinese cities. They have already overshadowed Hong Kong.

If you do that then you're considering 2 collisions, ie. you're considering 2 cars, both hitting a brick wall at 50mph. The assumption therefore is that the force felt by the wall is not great enough to overcome the inertia of the wall, therefore each vehicle does not exert any force on the opposing vehicle.

It's the same as saying that if you drive 2 cars into the same wall at 50mph the force felt by each driver is not the same as driving a single car into a wall at 100mph.

That is true obviously.

However if there isn't a perfectly immovable "piece of paper" in between the 2 cars, then you can't just ignore the force acting on each car, from the other car.

F = ma

Also, Newton's 3rd law states that forces generate equal and opposite forces.

So if you punch a wall, you are exerting a force on the wall, and the wall is exerting an equal and opposing force on your hand.

When car A hits car B going 50mph, the force is the mass of the car times the acceleration required to stop the car (ie. deceleration, acceleration in the opposite direction).

However that force is matched by a force in the other direction PLUS the force of each car attempting to decelerate the other car.

You have 2 forces for each car: the force felt by car A as car B tries to accelerate it in the direction car B was travelling, and the force felt by car B from car A that opposes that force, and vice versa.

So if we assume the cars are driving in an Elon Musk hyperloop tunnel under Vegas in a straight line then yeah, the forces felt by the drivers in each vehicle is the same for a car driving 100mph into a "brick wall" (or more accurately a big pile of bricks the same size and shape as a car with equivalent mass).

I'm sorry if I wasn't clear; I didn't mean to say that all LC questions are irrelevant. I was just asking if you're claiming that no company uses LC questions which are irrelevant.

And my "implement a quadtree" example was hyperbole; again I'm sorry if you didn't recognize it as such. I do suspect we have wildly different definitons of what questions qualify as "relevant to the position," though, so I'm not sure how far we're going to get in this discussion.
If you've never done graphics programming before, I wouldn't recommend starting with Vulkan. I would start with WebGPU via either wgpu (Rust + various bindings), dawn (C++), or the browser (JS). Or do raytracing on the CPU.

Once you've made a fairly capable engine, have rewritten it 1-3 times and are very comfortable with it, and are looking at profiles and going "hmm I wish I could do X to optimize this but WebGPU lacks support for it", then I would learn Vulkan.

Vulkan (and DirectX12) are targeted at existing engine developers who want to optimize every aspect of the rendering engine. It's not a very forgiving API, and learning the API (and how to use it optimally) is just one aspect of graphics programming. There's also linear algebra and coordinate spaces, PBR rendering theory, etc. It's a very involved field that's quite different from other programming fields.

RE: Vulkan requiring thousands of lines of setup, I think some of it is fair and some of it is not. Extension handling is definitely fairly cursed imo compared to how DirectX12 handles it. Memory allocation is rarely something that needs manually writing, using VMA is plenty good for 99% of use cases. On the other hand, device, queue, and swapchain selection and synchronization are all important. Sure there's a "simple" path where you just select the first device, the main queue, and use the default swapchain choice, but it can get complicated. Transfer and compute queues are important, and are a bit involved in requesting. Swapchain pacing is complex to get right, and you may want to support HDR/WCG displays. Vulkan gives you a lot of control, which is overwhelming at first, but useful for a lot of people.

I'm not against congestion pricing per se, but aren't these sorts of policies regressive?

Yes, there is certainly an archetype of "Accomplished physicist who has ventured outside their area of expertise and is patronizing the locals with confident proclamations that `this would all be trivial if you knew math better and made these obvious simplifying assumptions`".

> What you link is a specific law covering a pretty specific category of people, ones already in jail. Not exactly "demanding everything women have be man's"...

Why do you think that law was passed in the first place? It's because the current progressive position is that any male who says he's a woman should be allowed to access any service or space that was created solely for women.

This isn't just limited to prisons. Another recent instance: Title IX is being redefined in this way, which according to the UN will discriminate against and disadvantage women and girls in educational settings: https://www.ohchr.org/en/press-releases/2024/04/united-state...

> By saying the definitions are flexible I'm somehow reinforcing rigorous gender role stereotypes?

Yes. If you remove the female body from the definition of woman, what else remains besides sexist stereotypes? When a male says he identifies as a woman, what exactly is he identifying with? You can't identify with a body you don't have, so what could he actually be identifying with, if not these stereotypes?

Hmm, I don't know, I feel like America in perticular came away from WWII with pretty clean hands, bombing Japan aside, the pacific war devolved into something a bit grotesque. The American soldiers marched towards Japan carrying around the skulls of the Japanese as trophies. A representative gave Roosevelt a letter opener made out of a Japanese soldier's arm. The Americans were WAY more chill in the European theatre and generally fought "A good war".

The rest of the Allies always struck me more as cynical imperialists, and the whole narrative of the British desperately trying to stop that madman Hitler but Chamberlain loving peace too much to stop him as being a bit naive. Stalin saw things differently and saw the allies as trying to intentionally make Hitler stronger to keep the USSR in check. From that perspective, it's not shocking the allies went to war against the Nazis almost immediately after Molotov-Ribbentrop was signed. Plus you know, there were all the colonial shenanigans.

Also, with all that being stressed, it is actually unbelievable how comically supervillaniously evil the Nazis actually were. These were a group of people who made Josef Stalin seem ethical. It's hard to fight the Nazis and NOT be the good guys.
> in a malpractice situation, a physician could be liable if they made diagnosis or treatment decisions based on unverifiable LDTs.

That seems to be a senseless concern, since offered the evidence of a lab test, a physician should be prompted to investigate further. No physician (nor individual) should ever be making a diagnosis or treatment decision based on a single line of evidence.

More importantly, such results can help offer hard evidence to pressure one's physician to investigate a particular complaint, which can be difficult to convey or to convince the physician it's real. Physicians are often dismissive of things that they do not understand, or of certain classes of patients. Consequently many patients are forced to figure out the source of the problem for themselves.

With a lab based test result, you can go to a physician and say, "Hey, this isn't just my imagination nor some kind of over-reaction. It's tangible and externally verifiable."

And for those without a GP, waitlisted like myself (5+ years waiting here in Canada!), such tests can help one navigate our piecemeal medical system more effectively.

Yes, and it looks like the quickest, cheapest way to do that is by electrifying everything we can and generating electricity with wind, solar, and battery storage. In the US, the most economical way to get a reliable grid out of that is 2X energy overproduction and four days of battery (citation in another comment I posted here.)

With 2X overproduction, we've got lots of spare energy, so by the time we're getting most of our energy this way, we'll also have lots of energy for DAC, which can soak up the excess power whenever it's available.
Guess: the logs were on an ec2 instance that was thrown away regularly, and the overnight reports didn't give reproduce steps or timestamps; so when they checked it "works fine".

Tact is one thing, but if I were advising a younger person on this, it would be on cost/benefit of challenging and having a read for others' insecurity or openness.

Even in older age, many have fragile egos and may throw their weight around to punish you just for the insolence of contradicting them. It's worth knowing what's at stake, what's the upside. It's not enough to be right. That applies not only to subverting authority, but also popular conventional wisdom, as beautifully exemplified in anecdotes from the book the Scout Mindset.

As a driver you mostly care about the amount of deceleration you will personally experience.

If you have 1m of hood to work with, you're decelerating 100km/h to 0km/h over 1m in the wall case.

In the hood-to-hood case, depending on reference frame, you're either decelerating 50km/h to 0km/h over 1m or 100km/h to 0km/h over 2m (both hoods).

Either way it should be trivially obvious that running into a wall is going to be a much more violent experience. Likely the wall crumpling up the front of your car won't be enough to bring you to a stop before you personally impact something.

The problem with Venus cloud cities is: what's the purpose? What are people going to do there? Sit around and write software?

At least on Mars, you could potentially do mining. On Venus, you can't do anything really, because you'd have no access to the natural resources there. So what's the point?

The Moon is the only place that really makes any sense at this point. It's close, it probably has lava tubes, it has lots of natural resources for mining, it would be relatively easy to set up habitats and maybe do things like build low-g factories (could be many industrial applications there that we haven't thought of), and aside from being airless, the surface isn't going to kill you like Venus will.
Looking at the current state of humanity, I don't think so.
If you're talking about split-ring lock washers, I would think again. They do not accomplish any kind of locking, and may make vibration-induced loosening _worse_ by providing a small opening force. They are useless for almost all purposes.

> When they collide at 50mph, each car will bounce backwards at 50mph

This is the incorrect part. They would both go to zero velocity/momentum.

Momentum is a vector quantity, so has a direction and magnitude. Two identical cars with the same speed going opposite directions would have the same magnitude of momentum, but opposite sign. After colliding, their sum would be zero.

If you watch billiards you would see kinda the same thing going on.

The typical reason for a business to give a discount for paying for cash is so they can then evade paying tax on that income (at least, here in Australia, but it was my direct experience in the UK as well at least sometimes).

The discount has to reflect the fact that the cost of dealing with the cash isn't too far off the actual cost of paying card fees now. To the point where cash is so rare in Australia that cash handling companies are in trouble [1].

Our Reserve Bank recently suggested that businesses might soon want to charge customers who want cash /more/ - it seems possible that at some point in the near future anyone offering discounts for cash will just be instantly flagged for tax investigation!
