Sorry, no, Venice isn't what I'd call a real city. It's a tourist trap. AFAICT, the only people who sleep there are tourists. The "locals" who service the place commute from outside of the town.

When I went there I was at first enchanted by it, but as I did what I normally and go looking the social differences I didn't find it for a while - it is all shops, restaurants and hotels. So I kept walking. It was only one I was well out of the older parts, and well away from the tourists did I see the sorts of things I visit foreign places to experience. Things like a coffin being lifted down from a house window using a motorised ladder, a grocer in a largish boat overflowing with produce, stopping every so often to let the local women on.

I have no idea how these real places are fairing, but I suspect much better because the walls of the canals were higher.

As for the tourist trap that is the heart of Venice - this will just add to it's reputation. Parts of St Marks are under water every day. Walking through a church, a very well maintained and elegant church at that, and sitting on a pew wait the salt water lapping an inch or so below your bum is a novel experience. I heartily recommend it to everyone.

But once crass the commercialism of the place begins to grate take a walk to the real Venice, where the locals are born, marry and die. It's gritty, real and nowhere near as pretty, but I remember my walk through there far better than I remember Venice itself. I do hope the people who live there are OK.

At this point I wonder if you’re really just striking the trivial observation that the west is majority white and so are the homeless people there. In literally every state, black people are over represented among the homeless and white people are underrepresented. However, in most states, the majority of homeless people are still white, because the state population is mostly white. It is, in any state, a complete falsehood to say that homelessness is “a very white specific thing”.

Talking about Hispanic homelessness is much harder, because there are many variations on how studies count white/Hispanic, and because it’s a less visually identifiable group than black people. Let’s look at Tucson. Pima County was ~37% Hispanic in 2015 (https://www.tucsonhispanicchamber.org/uploads/5/8/0/4/580457...)
Tucson homeless population in 2016 was 30% Hispanic. Among adults without children, it was much lower: just over 20%. So non-Hispanic people are actually a little overrepresented, but probably looked very overrepresented among the visible population. And if we look at why there is that difference, my first thought would be that the Hispanic population is weighted towards children (about 50% of school enrollments, from that doc above) who are less likely to be homeless. So I would still disagree that it is at all a “white-specific thing” even in that location.
(calculated from here - https://dl.dropboxusercontent.com/apitl/1/AOcbyEzOLNSVbwFWOs...
)

And if we just look at white/not-white: you do realize that Tucson is over 70% white people, right? And the homeless population is also just over 70% white. That’s not any kind of argument for it being a “white thing”.

Well, I don't think other countries have achieved actual price insensitivity, in the sense of "fully inelastic demand". Fundamentally, for any scarce resource, supply, demand, and price are necessarily linked. Medical care is scarce - consuming a unit of medication or a time slot with a doctor precludes someone else from consuming the same. The allocation mechanism can be monetary (price), temporal (wait times/backlogs), or regulatory (restriction from certain services or treatments), but there must be an allocation mechanism. As far as I know, there's no country in the world where you can get all the medical care you demand when you demand it without consideration of price; if you're not paying monetarily, you're subject to rationing or restrictions that otherwise limit the demand you can place on the system.

In Singapore, for example, Medisave only covers drugs that the government has deemed cost-effective. Need a high-cost experimental medication? Not permitted. Denmark has notably bad cancer survival rates, much a consequence of long wait times for screenings and treatments. The US, by comparison, has some of the highest cancer survival rates in the developed world, arguably because Americans can (and do) spend on tests and screenings at far higher rates than other countries. IIRC, Americans get medical imaging scans at a rate roughly 100-1000% higher than patients in other first-world nations. Most of those scans don't find anything, and if you're a government bean counter deciding how to allocate this year's medical budget, they're going to be high on the list to cut or ration - but when they find something, those early warnings and immediate access to aggressive (and expensive) treatment make a significant difference.

- 100% walkable.

- you meet people you know all the time. Feels like a village.

- international. Many interesting characters live there. A village but an international one.

- beautiful and decadent.

And of course there's also a long list of negatives such as expensive, uncomfortable, wet, touristy etc....

I am reading these comment about their Wife being either smart, socially conscious or whatever it is, but still being sold into buying Diamonds due to Marketing, High Price Signal or Culture.

This completely misses the point, Diamond is Beautiful. We human, especially female likes beautiful things. It is no coincidence that humans around the globe, hundreds of different cultures over different continents all settles on similar gems stones. For whatever physiological reason we humans like Shiny Object.

And moissanite stone, as far as I have seen are no diamonds, may be to those who are less demanding, the colour and shines are slightly different. And to those who demands quality, once you have seen a beautiful diamond, you can not unseen it. There is a reason why Tiffany and Cartier still command a premium.

Ask HN: What's AGI, Exactly?
I'm not sure at what point one could define something "AGI". Would the following be AGI?

a robot equipped with a microphone, a camera, a speaker, that could walk anywhere, that does simple tasks (according to humans), that makes up an okay answer to any question (or simply answers "I don't know"), that can identify all objects and sounds with 99% accuracy and that sometimes makes new connections based on the content he mines on the internet?

To me that sounds like human level intelligence and it's basically here.
Maybe “necessary” is too strong, but “likely pivotal” is better.

If VR becomes widespread, and amazingly high quality, then almost everything we do will migrate to VR.

Once that is the case, we will have an unprecedented amount of data about human behaviour, and near endless data for training, experimenting, and testing AIs.

The problems of AI will become much easier to formulate: “replace this person in this VR scenario, interaction” etc. This will help drive research by giving clear goals.

More pragmatically, it just removes a lot of barriers to research and accidental difficulties ie you’ll just be able to fire up a VR rather than worrying about how your robot is going to pick things up or access real world data etc
>and their rampant materialism

Is this really that bad? How well do you think teens understand the issue from both sides? It's easy to be against materialism when you yourself don't have to worry about bills and food. It's a lot harder when you have to make choices in what you can and can't get because of your lack of resources.

Perhaps if teens understood money better there wouldn't be such a huge problem with student loans. But there is, which indicates that they're not very good at managing money.

Edit: this applies to teenagers of today. Perhaps if they are handed more responsibility as they grew up they would be better at managing money?
The paper doesn't really explain everything you need to be able to read the notation, but, being a tensor diagram aficionado, I have to say I found the way they encoded divergence and curl very exciting: it is all consistent and helpful for doing calculations.

The loop-around-a-tensor notation is calculating the covariant derivative. For example, if you have a vector field, the covariant derivative is a "matrix field," where at every point in space you have a matrix that can take in a vector there and spit out the component-wise directional derivative. The divergence graphical notation (connecting the two wires together) is equivalent to taking a trace of this, meaning you create a scalar field where at every point you take the trace of the matrix from the covariant derivative.

I guess all I'm saying is that the notation for divergence and curl are consequences to a couple of building blocks that have more generality. I'll also add that, like any language, it takes some getting used to.

> Why not just represent divergence and curl for what they are?

I'm curious how you would represent them for what they are. Maybe you have something in mind that would make calculations easier?

Yes, it is possible that they do not use AWS, but thats not my point. If you can offer a price which is a fraction of AWS' price (or for that matter of any other major cloud provider), why bother with gaming? Just sell your capacity 11x cheaper, whereas this is a lower bound for this factor. They should be able to sell it for even less.

Owning hardware does not make it necessarily cheaper. Most often to the contrary.

So by your approximation they still make -$23/month?

Either way, we offer a solid Factorio Server Hosting Service, where you do not have to bother with capacity limitations, resulting lags or an awful configuration panel. We solve this problems and we offer it for $2.5/player/month. If you want a smooth gaming experience when coming home from a stressful workday, we are the right choice. If you dont care for about the aspects mentioned above and you want to pay a few cents less per month, you should probably us a different game server host.

Our focus is quality of service.

To armchair-quarterback a decades-old incident: I think it was definitely the wrong choice to continue to LAX knowing that field (and the entire coastal region) was IFR. They were essentially controlling the aircraft pitch (and airspeed/altitude) solely with thrust and configuration changes.

It's a miracle (and it speaks to the superb piloting abilities of the Captain/crew) that they were able to maintain a prescribed glideslope while in IMC.

Having flown in the area for several years, I know that the marine layer never (almost) extends east of the 'Peninsular Ranges' of San Diego / South OC. There are a number of clear-air diverts to the East (March/Ontario Maybe, NAF El Centro, probably best) that certainly would have been a better decision(1), given the nature of their emergency.

Had the crew 'balled it up' on final approach due to vertigo or loss of SA in the clouds, I think it's likely that the mishap board would have found pilot error--due to poor selection of a landing site--as the final 'causal factor'(2) in the so-called Swiss cheese model that leads to a mishap.

Note 1: The pilot's concern with runway lighting is valid but I think a ten-minute breather above the clouds to coordinate with those fields would have answered the question on whether a tower was staffed. Pilot controlled lighting is also an option.

Note 2: And they would have balled up a large aircraft in one of the most densely populated areas in the U.S.

but that's not how many advertisers see ads

I've heard advertisers try and justify their work and it doesn't sound very convincing. The simple fact is they are paying to make you do something you wouldn't have ordinarily done.

As we have become more resistant to their activities they have become more underhand. Adverts will try and convince you that you can't be a good father unless you own an SUV, that your partner will become slim and attractive if you buy a specific perfume for her, that you will have a happy family Christmas if you just bought this oak table. This sort of manipulation is a scourge on society.

Ok, I'll take a shot: "it would follow that anyone tackling AGI would have some experience applying machine learning competitively in some public space".

No, that would absolutely not follow. (I'm a pretty good devil's advocate, but I can't with this one.)

And given AGI would come from some completely new breakthrough not related to the current practice of "machine learning", competitions may be completely moot. They may be great for finding the nice increments in the state of the art of machine learning, but they are unlikely to help much with AGI.

I could even imagine a stumbling AGI being very stupid compared to just about any machine learning solution thrown at it - yet being undeniably AGI. Like a dog not being very good at DOTA, Star Craft or Chess, yet it undeniably possesses some kind of general intelligence.

The Rand meta-analysis disagrees with your conclusion. Specifically, row 4 column 8 at https://www.rand.org/research/gun-policy/analysis.html

is "LIMITED". Rand was specific in their labels, and Rand does not assert "MODERATE" or let alone "SUPPORTIVE". So while you pretend to have a "consensus", the meta-analysis you hold in high regard does not say that. In fact it's 2 levels below "SUPPORTIVE". I.e. not "SUPPORTIVE".

Since you linked to the unintended injuries section, I'll point out the same thing, Rand's own conclusions dont rise to the level of "SUPPORTIVE", again, it's 2 levels below that at "LIMITED".
