They say "our systems" (presumably meaning AlphaProof and AlphaGeometry 2) solved one problem "within minutes", and later on the page they say that the geometry question (#4) was solved by AlphaGeometry in 19 seconds.

So either (1) "within minutes" was underselling the abilities of the system, or (2) what they actually meant was that the geometry problem was solved in 19 seconds, one of the others "within minutes" (I'd guess #1 which is definitely easier than the other two they solved), and the others in unspecified times of which the longer was ~3 days.

I'd guess it's the first of those.

(Euclidean geometry has been a kinda-solved domain for some time; it's not super-surprising that they were able to solve that problem quickly.)

As for the long solve times, I would guess they're related to this fascinating remark:

HN and other forums perpetuate a fallacy (that I assume isn't well known because nobody has published a research paper on it)... but "the wisdom of the crowd" isn't.

"Trusted voices" on HN are often not experts, yet espouse views which are not what the larger body of experts would consider correct. In addition, actual expert voices are drowned out by whatever the popular position is. HN also provides its own cultural bias, in that everything spoken on HN has to follow a rigorous cultural sieve set down by the guidelines, such that a "negative" view, even if correct, is considered either wrong or distasteful and buried. This is exacerbated by banning the use of humor to disarm controversial or heated comments. And this is the comments that HN does get; many opinions are never entered as comments here, so there exists a large knowledge gap. Then there's the "taboo" subjects like race, gender, religion, politics, social justice, etc which get buried for fear of controversy, so you're definitely not gonna find any expert opinions on those, as the stories just aren't there for discussion.

The end result is that often experts go unheeded or even downvoted, popular shallow opinions get upvoted, and substantive commentary based on evidence and experience is frequently missing. The fact is that we have no idea who knows what, or what's true or right. We just have "popularity" according to the particular cultural quirks of this site. So you can definitely find out "who thinks what", and who is considered to be more trustworthy to a HNer, but it has absolutely nothing to do with objective truth or the body of real knowledge that exists outside the world of HN comments. This is an echo chamber, but it's not a chamber of experts. It just seems that way because occasionally you see a minor tech celebrity, and people talk with absolute authority regardless of if they have any.

You want to find out who knows what? Look at their diplomas and careers. If they've done 20 years in a single field, probably they're an expert. If they have a degree (or multiple) in a field, probably they're an expert. If they spent half their life working on a single hobby, they're at least very knowledgeable in that field. But you can't determine that just by looking at who's talking about what or how many completely subjective "points" they get for what they say. Determining real knowledge requires analysis of specific criteria, filtered to get a higher quality result.
I believe you are misreading this.

First of all, this is not a sport and the point is not to compare AI to humans. The point is to compare AI to IMO-difficulty problems.

Secondly, this is now some hacky trick where Brute force and some theorem prover magic are massaged to solve a select few problems and then you'll never hear about it again. They are building a general pipeline which turns informal natural lamguage mathematics (of which we have ungodly amounts available) into formalized mathematics, and in addition trains a model to prove such kinds of mathematics. This can also work for theory building. This can become a real mathematical assistant that can help a mathematician test an argument, play with variations of a definition, try 100 combinations of some estimates, apply a classic but lengthy technique etc. etc.
That seems shallow and not really useful. Like sorting is easy, just take all permutations and look at each one to see whether is sorted.... it just might you take longer than the heat death of the universe to actually do that.

> there's no accepted definition of what an unsound type system is

Huh?

The cheeky answer would be that the definition here is the one the TypeScript documentation itself uses[1].

The useful answer is that there’s only one general definition that I’ve ever encountered: a type system is sound if no well-typed program encounters type errors during its execution. Importantly, that’s not a statement about the (static) type system in isolation: it’s tied to the language’s dynamic semantics.

The tricky part, of course, is defining “type error”. In theoretical contexts, it’s common to just not define any evaluation rules at all for outwardly ill-typed things (negating a list, say), thus the common phrasing that no well-typed program must get stuck (unable to evaluate further). In practical statically-typed languages, there are on occasion cases that are defined not to be type errors essentially by fiat, such as null pointer accesses in Java, or escape hatches, such as unsafeCoerce in practical implementations of Haskell.

Of course, ECMAScript just defines behaviour for everything (except violating invariants in proxy handlers, in which case, lol, good luck), so arguably every static type system for it is sound, even one that allows var foo: string = 42. Obviously that’s not a helpful point of view. I think it’s reasonable to say that whatever we count as erroneous situations must at the very least include all occurrences of ReferenceError and TypeError.

TypeScript prevents most of them, which is good enough for its linting use case, when the worst possible result is that a buggy program crashes. It would definitely not be good enough for Closure Compiler’s minification use case, when the worst possible result is that a correct program gets silently miscompiled (misminified?).

Yep - all non-primitive types in Java are `TheType | null` - TypeScript actually allows you to strip out the `| null`, which then means that sometimes you want to add it back in. So Java doesn't have a need for `Partial<T>`, it has a need for `NonNull<T>` and it can't express that at the type system level very easily right now (you can do it with type tagging and runtime checks inserted explicitly, but it's not very ergonomic right now)

Seems like confirmation bias. We often than not like to lionize successful individuals, but plenty of visions are false or otherwise fail. On the other hand, we tend not to remember group efforts because it's harder to remember multiple individuals at a time. But surely they do exist. Was there a single visionary behind Bell Labs? Xerox PARC? The traitorous eight? The Apollo program? The Manhattan Project?
Personally, I like how HN focuses on content and discussions rather than individual users. If I wanted to follow experts, I'd probably curate a selection on a social network like Mastodon, or kludge together some RSS feeds.

Also, I feel like this tool selects for active commenters, not for knowledgeable experts. Not to mention throwaway accounts.

Still a cool project.
If you tie your income and your savings together, you're not saving for a rainy day. A rainy day will wipe you out.

Ever heard the investment advice "diversify"? It's recommended because it's mathematically provable that you can achieve the same income with lower risk by diversifying away the co-variances between your different income streams.

In the same way that it's nice to go to the market and buy the phone you prefer, the car you prefer, the milk you prefer, etc. you should make investments that are right for you too from among choices.

Yeah what it's showing is that on iOS/Safari (user agent) it returns a maps:// protocol address. This makes sense of all the reports here - it's trying to direct you to whatever maps app you've selected. Redirecting to google maps makes sense if the server doesn't think the maps:// result will do that.

It's not from a digicam, it's a scan of a photo. The white bar on the left is from a subpar cropping job and is slightly crooked. The resolution (1275x1167) is higher than a typical 3:4 digital image sensor of the day, which would have maxed out at 640x480 in the late '90s to early 2000's, maybe 1024x768 for a really high-spec (expensive and uncommon) camera.

As for the "look", I'm not a photographer but this was likely taken on either a low-end handheld film camera or disposable jobbie, which were absolutely ubiquitous around this time frame because they were so cheap (practically free, until you went to develop them). The picture was taken on an overcast day at dusk, later in the evening. Just dark enough to auto-trigger the insufficient flash which lights up the middle of the image and puts everything in the periphery in a dark shadow.

I do like that the kid with the beer isn't looking at the camera and seems to have missed the point that everyone was supposed to be holding the ball.

I've noticed many roasters have only one decaf option. But there are exceptions. Equator Coffees has many blends available in both regular and decaf, with the decaf costing slightly more (e.g. $15.30 vs. $15.75 for a subscribe-and-save 12 oz bag). They advertise "decaffeinated using the mountain water process of caffeine extraction", which I believe is the same as the article's Swiss water process. Not sure if they have their own equipment or if they assemble their blends, send them off, get them back and roast them.
I work with a lot of economists. As such, I'd argue that people respond to incentives. Famous example being the cobra effect (https://en.m.wikipedia.org/wiki/Perverse_incentive)

Working mathematicians mostly don't use theorem provers in their work, and find that when they do they go significantly more slowly (with of course the compensating advantage of guaranteeing no mistakes in the final result).

A theorem prover is probably more useful for the typical IMO problem than for the typical real research problem, but even so I'd guess that even with a reasonable amount of training most IMO contestants would not do much better for having access to a theorem prover.

Having three days would be a bigger deal, for sure. (But from "computers can't do this" to "computers can do this, but it takes days" is generally a much bigger step than from "computers can do this, but it takes days" to "computers can do this in seconds".)

This will speed up their domestic electric mobility transition, and as their market saturates, they will eventually point the firehose of affordable EVs (from the built up manufacturing base) at the rest of the world that doesn’t punitively tariff. This should also contribute to demand destruction for petroleum for light vehicle mobility [1].

With every housing unit ever needed already built [2], China is going Big Tech and Clean Energy [3]. It was unfortunate how much real estate consumed their economy, but being the clean energy and mobility factory to the world (with an enormous global total addressable market) is a rising tide that lifts all boats.

A bit of my analysis is: perhaps the developed/Western world should consider similar subsidies?

> millions of Americans are hurting from years of rising prices...

...and very little corresponding increase in income. The last time the US minimum wage was raised was 15 years ago, almost to the day! Spend some time talking to people and you'll discover their actual wages, not inflation-adjusted wages, but actual wages, haven't appreciated much in the past 15 years. But boy oh boy have prices increased! As have corporate profits! Makes it rather obvious where the money is going, doesn't it?
I'm attacking nobody! I literally couldn't understand the point, so I said so: as stated, its premises are simply clearly false!

Your point, however, is certainly a good one: IMO problems are an extremely narrow subset of the space of mathematical problems, which is itself not necessarily even 50% of the space of the work of a mathematician.
While this might be true on the technical level you mention, I don't know the details, I think the general pattern holds true even for larger cities. Think of NYC, where many suburbanite "bridge and tunnel folks" choose to live in Jersey, Long Island, etc. to avoid the higher city taxes but have no problem availing of all the city-funded infrastructure. They even caused the state governor to backtrack on congestion pricing so they could keep driving their vehicles in at the expense of NYC residents.
Are you suggesting that someone from NK wouldn't be able to?
CAP was never designed as an end all template you blindly apply to large scale systems. Think of it more as a mental starting pointing, that systems have these trade offs you need to consider. Each system you integrate has complex and nuanced requirements that don't neatly fall into clean buckets.

I kinda see what the author is getting at, but I don't buy the argument.

However, in the example with the network partition, it relies on proper monitoring to work out if the DB its attached to is currently in partition.

managing reads is a piece of piss, mostly. Its when you need propagate write to the rest of the DB system, thats where stuff gets hairy.

Now, most places can run from a single DB, especially as disks are fucking fast now. so CAP is never really that much of a problem. However when you go multi-region, thats when it gets interesting.

It's amazing how many people believe that every company is publicly traded. The vast majority of companies do not have stock and never will.

If every company were owned by its employees, the net result would be higher unemployment, and many of those who found work would then do so as contractors. Hiring an employee is a major decision, especially for small- to mid-size companies. For a fledgling family business, giving an hourly employee an ownership stake in the company you and your wife started in your garage is a non-starter for most people regardless of their stated political ideology. For megacorps with deep pockets, mandatory ESOP would immediately accelerate the replacement of humans with machines.

If you look at the incentives you can fairly quickly guess a person's (and a company's) future behavior.

> Who themselves are miles ahead the entirely of work population that ever lived on this planet before XXth century, but that doesn't make their life any better, does it?

Eh. I‘d argue the average dirt poor Indian right now isn‘t far off from your 1800‘s Chinese rice farmer.

> You aren't entitled any gratitude from people, especially not on the basis that there lives is being made a bit less miserable because of policies you oppose.

This is untrue and I‘m not sure where you’ve made this observation. I wholly support these policies for German people. I have voted for a lot of them in the past and I‘m not a conservative. I love my country and the people in it and I voted progressive in every election I could.

Which is why I‘m getting angry when people spread straight lies that our people on welfare here in my country regularly go without food or live in awful states of disarray and poverty. We provide so much to people and I‘m proud of it. But I‘m also realistic in the way that we can‘t provide this level of welfare to just any outsider, and that welfare is not supposed to provide a life of leisure activity.

> I'm not arguing the opposite, but you did insist that these people lived comfortably. This is obviously BS and I'm glad to see you're retracting it now.

Nowhere in this thread did I state such a thing. I merely said they and their children their basic needs met, which is true. I‘m sitting in my office right now while my partner - an elementary school teacher - fills out forms for the kids in her class with parents on welfare, for them to be provided with any needed materials and money for overnight school trips. I love this. This is good. I didn’t have the privilege when I was a child. How are these people struggling exactly? They live in Munich, the most expensive city here, in one of the most expensive parts of the city, on welfare.

> , you started this conversation with factual lies (which, on the opposite, isn't OK) about people “easily living” on welfare.

Prove where I said anything about easy living. Quote me. It‘s you who is lying and I‘m getting annoyed by this conversation.

> I give you the benefit of the doubt that you did not make this lie on purpose by yourself, and given that this is a recurrent trope of right wing politicians on TV, it's fair to assume that's where it came from.

Nice resort to ad hominems. Note that I have spared you these baseless attacks. I would have expected you to keep this standard up as well. How disappointing. Maybe consider that differing opinions are not always propaganda you might read in the Bild, but sometimes come from people‘s real experiences.

I came out of this system and fought my way out of it. You‘re denying me not only these anecdotes but you and other posters in this thread also argue against information that can be easily found on our official webpages for welfare, all because you assume I‘m some kind of far right idiot. I‘m a bit sad for you honestly.
