Does this mean controllers still have a responsibility of separating aircraft under a visual approach? (A comment in a sibling thread mentioned that Lufthansa pilots are allowed visual approaches, but are not allowed to be responsible for visual separation at night.)

Edit: sounds like visual approach means ATC do not have responsibility for separation. I thought the entire point of IFR (which – according to you – visual approach falls under) was that ATC is responsible for separation!

Well, I think there is a clear difference that I'll try to make clearer. Most people, when they talk about buying an experience, essentially want to do something fairly passive, that is directed by someone else. Like going bungee jumping - pay lots of money, turn up, do as you're told. Or go to a concert - buy tickets, turn up, do as you're told.

As opposed to something like a hike, where you need to contribute a lot of your own decision making and energy into creating the experience. The dollars you spend on food and gear are a bit beside the point.

> Rare experiences that have a low supply but high demand are naturally going to be expensive, just like rare or hard-to-manufacture things.

I don't think the rarity of the experience is relevant. Watching the aurora australis in Australia is rare, but it doesn't cost anything. The cost of experiences is mostly about the labor. Very niche experiences might be expensive because there's a high staff-to-participant ratio, but I wouldn't call that a scarcity cost exactly.

International flights are common but expensive. So are 4 star hotels and fancy meals. And escorts for that matter.

> That said, my intuition would be that the cheapest experiences are pretty much always cheaper than the cheapest things, and the most expensive things (e.g. one-of-a-kind art, rare objects, etc) are generally more expensive than the most expensive experiences.

Probably. Though it gets a bit fuzzy how you define experience. Running for US president is extremely expensive and kind of an "experience". Probably the most expensive genuine experiences you can buy are space tourism trips, which cost in the millions. Although arguably high stakes poker is just an expensive experience for some people.
Sure, light gets quite simple as long as you can evaluate path integrals that integrate over the literally infinite possible paths that each contributing photon could possibly take!

Why are taxes paying for ATCs at all? The airports/airlines should be footing the entire bill
A variant of the second-system effect: one decides to reimplement something from scratch to incorporate all the lessons learned, avoiding the pile of hacks that accumulated over the years.

Then, as the project grows, you find people have been relying on hacks for so long you need to reimplement them. But your new, clean version is not designed to accomodate such abominations, so you need, very inelegantly, to hack them in.

Now you're back at square 1. Until the next naive engineer that decides to do the things the right way, once again.
“Expensive” is always a relative term. The Swiss have a good overground rail network and for example branch lines sometimes run combined cargo/passenger trains. No need for dedicated tunnels here. Payoff in a city, especially with little existing rail infrastructure may look different. Hamburg for example tried to establish a 45cm diameter tube mail system in the 1960ies https://de.m.wikipedia.org/wiki/Rohrpost_in_Hamburg and that seems like a more viable concept for a city than a full fledged rail tunnel. The system ultimately failed for multiple reasons, but one was that the vibrations cause by cars and trucks damaged the tubes :(
In order to drive this point—What kind of arbitrary safety policies are ATCs to expect and service?

If there are 200 airlines landing at SFO, you surely cannot expect ATC to make exceptions and argue about this or that. We need upfront, transparent and written procedures and policies.

Luthansa should notify SFO of their requirements before departing. SFO would have the right to reject their "safety" policy. And we wouldn't have this sticky situation.
If the alternative is building more road and rail through mountains, a 6M tunnel might look like a good option. Less rock to remove.

Discovering Cool Ideas Making Money with AI
I am not an expert, but at-spi doesn't solve the problem here as it was already discussed in the slack for the talon software. Basically "Accessibility software uses the at-spi protocol" seems to be an over-generalization.

The important bits:

> if you only say "accessibility" you may get the response "but at-spi2 works independent of x11 or wayland" the problem with at-spi2 is that it's opt-in by the application, so some programs just don't show up at all. the coverage of at-spi2 in video games is basically zero, for

and

> [...] wayland's stance on tools like talon is 'no' [...]

I may also need to switch back to windows if X11 support is dropped "too far" before wayland is there in the accessibility aspect.

As a game dev, I'm starting to feel like ECS isn't the right paradigm. Seeing this 700 nodes graph with all the dependencies screams technical debt and domino effect (changing one small system would impact a lot of other ones).

In Europe it is quite common for airline companies to only allow their aircrews visual approaches at their home bases (e.g. Amsterdam for KLM) or, in case the company uses several hubs, on those hubs.

Nice list.

>making wooden boxes

Can you describe how you do that? I mean, I can guess in general, because I have done a little carpentry earlier, and making boxes is somewhat common sense anyway (getting and assembling the pieces), but still would like to know how you do it.

I can guess the first part: you collect and cut the necessary wood pieces for the sides, top and bottom of the box. But even that is not fully obvious. What kind of pieces do you get?
Ones of a standard desired thickness, from a carpentry supplies or timber shop, or do you buy logs or planks and cut them to the desired thickness and length / width?

How do you fix them together? With nails/screws or some sort of glue? Not sure glue would work for thinner box sides.

Asking because I want to make some myself, to store things.
No what is needed is that the armchair experts shut up and start contributing to actual Wayland development.

The one doing the work decides how its done.

Third-party code hidden in a black box cannot be within the purview of your first-party tests. There is no way for those tests to know that the third-party code exists. It's hidden away in a black box.

If a third-party library within the black box is executed during the execution of a test, you may incidentally discovery cases where the library produces something not conformant with your documentation, but that is in no way explicit.
I googled "iterative recursion " and couldn't find a definition. So is it judt iteration? And then, what languages don't have iteration?
Again, I don't trust politicians, and I have good reason not to. You need multiple sources of information to corroborate in any setting you care about.

Plus, while it's true that in some government systems you only vote for a specific person, in many others you vote for a political party, and they allocate people as needed and according to the total votes they got. I think this system is far more common than the other one, and it is the system I live in (for parliament and town councils - it's true that for presidential and mayoral elections you vote for a single person).

Finally, having "a board" of some 2 million or 20 million or 200 million people is entirely different from having a board of 10. And then, social media is exactly one of the ways I can collaborate with my other "board members" at this scale.

Already if I'm a board member and not a manager, then much of your metaphors die away: active board members absolutely do more than read reports from their CEO, they read newspapers and watch analysts talk about their business. They don't rely entirely on the CEO for info on how the business is doing. And I have yet to see a company led by 200 co-CEOs, each chosen by a different board - and yet this is how must countries operate. It's almost like democratic countries are a totally different kind of organization than autocratic companies, and require totally different means of interaction.

In addition, CEOs are legally liable if they lie to their boards about the state of the business. Politicians are very much entirely protected for any and all things they say to the public about their activity. Your mayor could publicly tell you that they have paved your own driveway with gold and that they are increasing taxes to pay for the maintenance of that gold that doesn't exist, and it would be completely legal for them to do so.

All geometry is mathematically precise, still made of flat triangles that only approximate curved surfaces, every edge and corner is infinitely sharp, and everything related to materials and interaction with light (diffuse shading, specular highlights, surface roughness, bumpiness, transparency/translucency, snd so on) are still the simplest possible models that five a somewhat plausible look, raytraced or not.

> This is interesting. Does that make you smarter?

I'd rather not think in terms of "smarter" or "intelligent", since then you open the discussion to nitpicking what we mean by those anyway. I'm more interested in how to think reasonably fast and accurately, i.e., how schools typically measure smarts. There these shortcuts absolutely help.

> Wouldn't having a total grasp of adding 6 seven times be considered smarter than using that shortcut?

Not necessarily, since by having to do more calculations exposes you to the risk of errors, and being overall slower. The user AlanYx had a very nice response to my previous comment on this.

> And wouldn't the logical evolution of that mental shortcut be to simply use the tool in your pocket instead?

Well.. Depends. If every time you see a multiplication, your immediate reaction is to go to your pocket and start typing numbers, you have a lot less feeling for the numbers themselves, and your flow of thinking is interrupted by thinking about the phone.

> Is it smarter to memorize math shortcuts that you don't actually need, or is it smarter to circumvent them and employ your attention fruitfully elsewhere?

Ideally, sure. However, in practice what tends to happen is that you do the calculation with your phone, get your answer, look at the phone in your hand and see all the social media notifications. The attention then goes to checking the messages, reacting to a funny meme and scrolling the latest social media outrages. You can't really think of the phone as a microchip in your brain that instantly provides you with the correct answer, it comes with its usual drawbacks too.
Im a bit surprised that this (very C++ biased) post gets such traction on hacker news.

J1772 also lacks a neutral conductor. The 3rd largeish pin you see in the plug is actually a ground connector. Its longer so that its first to make last to break which is a requirement for most ground pins. I assume both J1772 and NACS use their ground conductors for neutral when in V2H mode since a ground conductor wouldn’t really do much when the car is feeding power to the home. Both plugs have 5 pins.
But it is not situation in Wayland - it is simple - so you need to implement hacks at a different layer (it is often impossible to implement them on the Wayland layer). No matter how much stuff you throw at the compositor layer the core is unaffected.
Not clear why they want to put that into the tunnel. There are already autonomous solutions for last mile delivery: robots using pedestrian sidewalks. No need to bore anything, easy to navigate and to rescue if there is an issue.

Ask HN: How can AI help as a shopping assistant?
Hi HN,

I'm developing an AI-based shopping assistant and I was looking at some feedback on the idea.

Assumption: When somebody needs to buy a high-value item there's usually some research involved in finding the right fit and comparing different products. My idea would be to provide value by simplifying this process.

This is a short video demo of the current state of the tool: https://www.youtube.com/watch?v=C5KVqcfQpB8 (it's a WIP and there are still some rough edges).

The way the tool works is it asks some questions in order to refine the search, and then evaluates the products based on your answer. After ranking, the products are shown and the requirements are marked as satisfied or not. There's also a Chat with AI feature where you can ask questions about the products and its reviews, if you need extra information.

There are other features I have in mind, like product comparison, but I'm slowing down a bit and looking for some feedback before developing something that nobody wants.

At the moment it's limited to Amazon.com, but the plan would be to extend support for other online retailers (which ones? I'm targeting US market but I'm not sure which would be worth to add, if any).

Do you think it is viable? Is there any value in this or you prefer to just search yourself on Amazon.com (maybe this holds for the HN demographic, but what about "normal" people)? What kind of feature would you like to see?

These are the kind of questions I'm asking myself, so if somebody wants to chime in and give their two cents I'd appreciate it very much.

Thanks!
I used to change an objects class itself in runtime in JS by changing its __proto__ property.

I don’t think that works anymore, but at the time I could create plain value objects and later make them class instantiations (on a small system way back when, this was a nice speed up due to a now uncommon pattern of having data first and waiting for the classes to load).
I run it as a Wayland client since a year or so now.

The only problem I know of is that screen sharing does not allow you to select an audio stream which has already spawned multiple hacks / modded clients over the years (and might also apply when running as a X client IDK)
This is an interesting idea and I’ll be curious to see if the economics works out, but I hope the company realizes that “pipe dream” does not have positive connotations.
God I already resent how much discord is a thing in the present, I really hope it’s not the future. Using a chat app as a forum / social network just doesn’t work for me.

I wonder if that actually works... It still tracks location, obviously Cookies (which you probably delete for this) and possibly a lot of other things. Maybe YouTube even maps your IP address to previous logins and uses that information "just slightly" in order to not throw you off...
I'm not sure how that would work. Can you give an example?
Except Nios can both charge and swap.

You can have a 75 kWh battery most of the time, swap to a 150 kWh for a road trip, and then swap back to a 75 kWh for your daily driving.

It means you don't own the battery, but it also means you can change to a new battery whenever you want.
Jujutsu–A Version Control System
That's right! If you want to spend on chess only a couple of months or beat your friends, then short-term patterns and gambits would be the best choice :)
> In China, you can buy a Nio car without a battery. You subscribe to BaaS (Battery as a Service) and pay a monthly subscription fee. The battery stays on Nio’s balance sheet. In this case, you can upgrade the battery on demand. If you subscribe to a 75 kWh battery, you can upgrade to a 100 kWh battery for 50 yuan (7 USD) a day or 880 yuan (123 USD) a month. This would make 150 kWh an excellent option for a short upgrade when going on a long trip rather than being “a daily driver.”

That is a very interesting model.
Presumably "Wi-Fi" these days means "any Internet connection that’s not cellular". And to be fair, cellular data mostly travels underground too.

Anything which relies on time coming in as an implicit variable as internal state is doomed to have legions of undebuggable problems.
In the past with Java 8 JFR wasn't free for use in commercial production environments. So we built our own profilers. It's nice that with NFTC, Oracle allows you to use JFR in production from Java 11 onwards. But they can revoke NFTC anytime. So, it is still wise to develop and use open-source or private alternatives to JFR. Besides JFR still doesn't profile everything well and you still need to build infrastructure for integrated distributed profiling and tracing.

While this is true, in some sense it is also a feature and not a bug. You don't always want the whole world seeing what you're writing. While Discord doesn't offer complete privacy (unless you restrict access), it provides good-enough-privacy in the same sense that you don't have complete privacy when having a conversation in a town square, but it's private enough. A couple of people might hear what you are saying, but your conversation isn't permanently and publicly archived.

This has its disadvantages, as you point out, but it also has advantages. What I really like about Discord is the fact that people actually connect with each other. I have never meaningfully connected with anyone on Reddit. Discord enables human connection for two reasons: (1) you have a village-sized group of people, meaning you can actually keep track of individuals and your relationships with them and (2) since it is private enough, you can allow yourself to be more vulnerable.
