> This is not at all what it's about. First of all, "incompleteness" has a very specific meaning in logic, namely that the following conditional (what we call "completeness") does not hold hold for some formal system S:

> Γ ⊨ φ → Γ ⊢ φ

That is, unfortunately, a misunderstanding because the words "(in)completeness" have two very distinct meanings that are both used in logic.

One is the completeness of some system of logic, namely what you mentioned: "Γ ⊨ φ → Γ ⊢ φ". That's provably true for fist-order logic (though not for second-order logic), giving rise to Gödel's completeness proof. It remains true when Γ = PA (more specifically, first-order PA). In other words, any truth about numbers that follows from PA has a proof.

When we talk about the incompleteness theorems, however, we're talking about the completeness of theories. A theory Γ is said to be complete whenever for all sentences we have either Γ ⊨ φ or Γ ⊨ ¬φ. While there are examples of complete theories (I linked the Wiki article in a comment more up-thread, but it includes simple examples like the theory of dense linear orders sets with endpoints), it is also easy enough to construct a theory that is not complete. In particular (and this follows from the first incompleteness theorem), first-order PA is not complete. What this also implies is that not every true statement about the natural numbers follows from PA, or equivalently, that there are models of PA, i.e. structures in which all axioms of (again, first-order) PA are true, that are nevertheless distinct from the natural numbers because some sentences that are true in the one structure are false in the other.

More precisely, the first incompleteness theorem states something like "any effectively axiomatisable theory that is sufficiently strong is incomplete", where "effectively axiomatisable" means that we can determine in finite time whether something is an axiom of that theory, and "sufficiently strong" means something like "can encode every primitive recursive function" (the exact formulation depends a bit, because there are several different "flavours" of the first incompleteness theorem). In particular, it also states that any theory that includes Robinson arithmetic (e.g. PA) is incomplete.
Ask HN: How do you run code reviews?
It seems that there really isn't standard to conduct code reviews, even within teams. We're trying to understand what the industry views as best practice and the workflows they found most success in.
I have a good friend who runs a smallish (100 person) company with about 30-40 (mechanical) engineers. One of their long-term custodians got ill for a long spell and so engineers were asked to take out their own trash. Some people just refused to do so, to the point it got smelly and affected the org. One of the execs got fed up and took all the smelly trash out herself one night and then started going around and individually directing the engineers in person to take out their trash when she thought it was too full. For the people who didn't take out the trash, it was considered in annual reviews.

Be thoughtful in what you evaluate as a "bogus" task. What is hard or complex isn't always what is important or noticed.
Your heaven sounds like my hell :) I don't want to live in a super dense metropolis filled to the brim with high rises where I cannot barely see the sky, and people are jammed into streets like cattle and no one has yards. If you do there are a ton of cities in America that are not in California, see New York, Chicago etc. Its funny as everyone who complains about California's high housing costs say the answer is to turn the entire state into Manhattan.

I think a better approach here is to focus on the supply side of things which is completely driven by companies that want people in the office and the offices are in SF or Palo Alto/Mountain View etc. So the answer here is either allow remote work and encourage people to leave California, or break up the head offices and move them across the country into less expensive areas.

Before the tech boom houses would go for $500-600K in San Jose(I should know as I bought a place in 2013 for $550k) so this high housing crisis is totally artificial and recent. It also doesn't help that having a million+ engineers/tech employees making $200k+ a year all crammed into one geographical region which is constrained by water and mountains.
What I found best is a strap with a narrow pouch sewn into it.
'Arrival’ writer team for Ted Chiang story ‘Division by zero’
Are you aware of any resources that talk about what the design of a "cleanroom" city might look like? I always think of a high rise surrounded by parks with a subterranean train connecting it to the rest of the surrounding society.

I like the idea of being able to be alone in nature easily but still living with modern conveniences. American cities (at least LA, SF, and Seattle) all require a car.

The worst depression of my life was living in San Francisco and never being able to be alone in nature. (I was very broke and didn't have a car.)
I've been watching NotJustBikes[1] on Youtube recently and he really drives the point home of how screwed up infrastructure is in the US and Canada. The problem for us seems to be cultural, we consider public transit to be a form a welfare rather than actual public infrastructure. We consider taking the train of the bus a thing you do if you're to poor to own a car and anytime expansion of a subway system is considered, there's always the kneejerk reaction of "you will bring crime to the suburbs".

And anytime we do build a mixed use development, we make sure that it's marked as "trendy" and "hip", as to not give the impression that this should be a normal mode of development. Anytime a development like this goes up, property prices around the development are out of reach to working class families and that even further drives the point home that this is not a normal mode of development, rather a playground for the wealthy (and you're going to need a car to get there if you don't live in the million dollar townhomes around the corner).

When these mixed use developments do go up, American's are amazed by the walkability and livability. News outlets do puff pieces on these new developments and everyone is happy about it, then when it's time to do more development around the city we go back to the old ways of segregating everything to the nth degree.

This is awesome, reminds me of some of Bret Victor's work.
Yeah there’s a huge black bezel around the whole thing.
> a) Apple restricts iPad OS so much, that it's difficult to make good use of that fantastic hardware. It feels weird that people ask questions like "what can I actually use that power for?"

Really, I can't think of a ton of uses for desktop/laptop hardware this powerful. And I don't do any of them, gaming aside (I have a mediocre Windows PC for that, and even that is often using only a fraction of its power for gaming).

The one and only time I've given my m1 Air a real workout is playing with one of those AI art generators, but it's not like that was something I needed to do, or I'd have felt like I was really missing out if I hadn't done it. I did it because I could and it was low-effort.

Faster compiling is nice I guess. That's... it.
> The migration to electric vehicles will happen, and must happen, over a couple of decades - and likely more time after that for heavy-duty use cases.

EV1's first appeared on the road in '96 (and it wasn't the first EV), so that means we've got a few years to go! ;-) Either way, California's plan is well within a "couple of decades".

> Trying to go faster will generate needless and extensive backlash, cost a lot of money, and lead to a lot of unsatisfactory experiences.

Same goes for not migrating, so you pick your poison.

> Somewhere along the adoption curve, electric vehicles will be cheaper than gas, and they are already (in many ways, though not range!) better than gas.

They already cheaper than ICEs.

> Therefore, even though subsidies were instrumental in getting electric off the ground a decade ago, it makes no sense to further subsidize at this time. If there is an irresistible urge to spend more money, spend it on infrastructure.

You might want to check the particulars on Prop 30. It does put money into spending on infrastructure.

But hey, if we want to take back the subsidies on gas instead of increasing subsidies on electric, I'm okay with that.
Well, this was held up as a universal truth because it doesn't depend on units, and so those don't need to be defined... But we still can't just show them the image '1/137' and have them understand the characters and operations. Our presentation isn't universal.

And I would argue that showing the length of distance we use isn't fundamentally different than explaining which syntax we use for division.
Even after they changed ownership?
I've used GitHub around an order of magnitude more than Codeberg (mostly for my older repos and other people's current repos) and GitLab still, but from my limited sample size using Codeberg, it's been down an order of magnitude more than either site you mentioned.

Agree to disagree, I suppose. Another comment in this thread suggested using the value of pi to demonstrate intelligence, but you can imagine alien civilizations without the same reverence of pi as we do (if they are large enough). I mentioned in another comment that you can also imagine small enough aliens not inventing a real number line because they do not have the experience that everything is infinitely divisible.

I believe our difference is that you are presupposing that aliens will have essentially the same experience with reality that we do. I agree that if somehow a separate human civilization evolved in another galaxy, their math would likely look similar to ours. But you can imagine aliens that have very different experiences of "what actually works in the real world" (due to experiencing a different set of physics, such as at a different physical scale) and thus come up with different math.
Much of the Earth's surface is not suitable for growing trees, either because it's too dry, to wet, to cold, poor soil or lack of soil, etc. The article gives examples of planting in places where trees don't typically grow, on coastlines and in deserts, so it's not at all surprising that the trees planted there died. This is why I've always been skeptical of tree planting initiatives. In areas where they can survive, trees will just naturally appear on unused land, there's no need to plant them. If this isn't happening on it's own, it's probably because the conditions there aren't right for them.
And indeed i think you should have the option. But i dont think either of us should be forced either way.
The migrant workers in construction are mostly from India, Pakistan, Afghanistan and Egypt.
Five digit years are annoying difficult to parse. Adding leading zeros is redundant and wrong. Once you move away from the treating the non-zero leading digits as significant it raise awkward questions like: why five digits instead of six?
Why does no one want to subsidize ebikes? If they do they only knock off a few hundred while electric car subsidies are often in the several thousands. We could fully subsidize like a half dozen ebikes for what people sometimes get in electric car subsidies.
Right now I'm drawing comics using CLIP Studio Paint, which really is a desktop app that runs seamlessly on the iPad (literally it appears to be the same code as what I have on my Mac!)

Each page is ~5000x7000px with dozens of layers including many effects and even 3D models. Even my 2018 iPad Pro breezes through this workflow. With the pencil, it feels like exactly the right device for what I'm doing.
I think he's literally in the process of invading and subjugating a neighbor, actually. The Saudis might not call what's going on in Yemen an invasion, but it sure looks like it from here.
Buying some of the most expensive real estate in the world with “just compensation” seems like it’s more than a stroke of a pen.

Further, the court cases this will bring will take _forever_ because one side will be extremely well funded and the other side will be the city of San Francisco. Not the stroke of a pen.
I don't think so. I think Covid was unique in that it occupied a sweet-spot in it's severity. A more severe virus would play out very differently. I don't think we'd see such a huge conspiracy movement around it and much greater compliance from the population.

The danger of the covid virus was concentrated in specific demographics such that a lot of people didn't directly see how dangerous it was. This created a disconnect between what was being reported vs what people saw with their own eyes, creating the perfect environment for conspiracy theories to run rampant. For example, I don't know anyone that died or had a bad time with it, nor does anyone else in my family/close circle. But that's because I don't really know any old or medically vulnerable people, but with our aging populations in the western world this group is actually huge. We had people dropping like flies in certain sub-groups while in others nothing much happened and only where the groups intersected was it visible how bad it really was (healthcare workers, people with old grandparents not taking it seriously). It also doesn't help that older demographics almost always have something else wrong with them and Covid a lot of the time was one contributing factor that pushed them over the edge, this really fueled the conspiracy theorists narrative of falsely attributing causes of death to "inflate" numbers.

I also think the media took a wrong turn in it's messaging and told too many noble lies. It was really important that the young and healthy also thought that this might be real threat to them personally so they'd actually take it seriously and stop spreading it. But young people would lookup the statistics for their own risk and would see fatality/complication rates of sub 1%, and also note that those affected were primarily the morbidly obese and immuno-compromised. I recall seeing a lot of articles indicating that there was a surge of young people in ER and articles showing obituaries of young people in order to hammer home the message that it was a real danger to them too. The problem is the official statistics didn't back that message up to the degree that it needed to, so you had this big disconnect that was exploited heavily by conspiracy theorists. IMO this was likely a misguided effort directed towards reducing spread, because it was determined that quarantining to save other people wasn't a strong enough incentive to curb risky behavior (which is depressing), but backfired heavily and likely caused more harm than good.

If a more serious virus came around that had fatality rates in the double digits, I don't think conspiracy theories would be able to form. Because very quickly people would see people they know in their lives dying/becoming extremely sick. There's no uncertainly/disconnect to exploit in that scenario like there was with covid.
I'm not too sure yet, but I wouldn't be surprised if we wake up one day, and just like how it went with Facebook buying oculus, we will all of a sudden require some "microsoft account" to log into Github. Then more layers, and more, until there is nothing left.

Either that, or you wake up one day to see that Microsoft have stole your open source software and Microsoft says "but muh AI".
That seems like a big distinction…
Would you count subsides for fossil fuels as externalities? ;-)
i was actually wondering about this. doesn't section 8 housing vouchers take care of this?

it also seems like it could lead to increased rents, if you have the government guarantee rent will be paid, you can raise it by a lot and not worry about people not paying, or even not being able to afford it.
Supabase. It’s an incredible product (greases so many friction points in pg) and the team is awesome. They do such a good job with communicating.
So far 2022 has been a great year to buy 2021 Apple products for me. I got an iPhone 13 Mini slightly discounted from the old price, an iPad Mini, again with a ~10% discount, and a Series 7 Watch, discounted. The current generations of all of these products are rather disappointing and significantly more expensive here in Europe. (The plain iPad was my alternative to the Mini, so I'm mentioning it)
Didn’t CA have a surplus? Doesn’t CA already have the highest tax brackets for the high earners?
Qatar is abusive and I'm having a hard time finding anything good to say about it, but nevertheless that particular fact seems like it might be being taken way out of context.

Qatar has 2 million migrant workers. The 6500 is taken over several 10 years, according to the Guardian article that nathanaldensr posted in a parallel comment, but to make sure I'm not going easy on Qatar I'm going to assume they took place over 2 years.

6500 deaths over 2 years in a population of 2 million is a death rate of 162 per 100k.

I assume that the migrant workers skews young, so let us compare that to younger people elsewhere. I tried to compare to some of the countries that many of the migrant workers come from but had trouble finding non-paywalled data. So I'm just going to compare to the US.

The death rate in the US for males 15-24 is 100 per 100k. For 25-34 it is 177 per 100k. For 35-44 it is 257 per 100k.

The Qatar death rate then doesn't actually seem to be high. It seems to be reasonably inline with what you'd expect from the sheer large number of migrant workers there.
The only difference between costplus and walmart/cvs/Kroger/Costco/walgreens generic options is costplus did a viral marketing campaign spamming Reddit, Instagram, tiktok, and news websites.

Costplus is not going to make a dent because they are not willing or able to invest the billions needed for R&D and clinical testing of medicines, and then release the IP/patents to the public. Nor are they going to build and develop the factories needed to make the medicines.

Hence costplus is just an increase in the supply of middlemen, not an increase in supply of medicine. When they develop a new medicine to treat hemophilia and give it away for cheap, then they can be said to have walked the walk rather than just talk the talk.
They very well could, but it is plausible that they do not.

Certain facets of mathematics however, it is not plausible that they do not share.

FWIW, you can pair a regular Magic keyboard & Bluetooth mouse to most iPads. The folio keyboard didn't have ESC (never owned that, can't comment), but it didn't mean it wasn't physically doable
Why would the wealthy leave when they enjoy some of the most favorable property tax terms in the entire country in the strongest job market in the entire country
Why do the support costs go to zero? I would think iPads would bring their own set of problems/hazards that laptops may not have.
I wonder if Apple is trying to go after the educational market to have iPad purchased instead of Chromebook's.
They're all pretty much the same. You could choose any one at all and be much better off than using medium. It's easy to switch afterward anyway.
You don’t need a ground rod for an EV charger, the service is already grounded and bonded and the EV wiring will have a grounding conductor.
How do automated birthing pods and human biomass recyclers affect user identity verification compliance and lifecycle testing requirements? I don't think your plan is well thought out.

They work for some people not others I guess.

I was a cashier for a couple summers. There were a couple members of staff that were really experienced experts who could really fly through the checkout, but there were plenty of us that were just kids working over the summer...

Supermarkets have always looked to save cost, it is a price sensitive business after all. At some point you'd give a list to the clerk and they'd put your order together. I'm sure people were annoyed when they had to start doing that clerk's job.
>"Think of this the next time you're sitting in traffic - is that freedom you are feeling now?"

Not all trips taken in a car experience traffic, and not all commutes experience heavy traffic. When people talk about the sense of freedom afforded by owning a car, they are talking about spontaneity and not needing to deal with strangers in a crowded space.
A lot of the items described are problems in ontologies

> One the other hand, the owner of Giphy absolutely does get to limit which websites get to continue displaying the gifs that several years' of their user-generated content backlinked to Giphy.com

I guess my question would be so what? You can cache them on your own system, if you wanted. However, I doubt historical shit posts and reaction gifs have any real value to anyone. Frankly it seems laughable that Facebook paid $660m for Gify in the first place.
Jira's main problem is that for most developers, this enormous piece of enterprise software is strictly inferior to a swimlane app they could build in a week. Lots of features in there for the benefit of managers and PMs that ultimately amount to more administrative work and process for developers.

Some places it's bad enough that Jira is used to appease the people with the purse strings, and the inputs have no bearing on reality at any given moment, while all the real workflows are tracked using paper note cards pinned to a cork posterboard that sits on Joe's desk behind his monitors.
I’d have to agree. Just bought a used 7th-gen iPad for that price difference.
Yeah, compared to Windows of the time it did come up short in Power User readiness. Especially by 2005. Using it in 2005 seems kinda late in the commercial game for CDE.

UP said that mathematics is universal. I believe it models only our perception and understanding, which are informed by our biological, evolutionary imperatives.

Reality itself is beyond us. All that we have at our disposal are our perceptions, which is what we are modeling when we "do math". Mathematics is not universal, it's a language that we use to communicate what we perceive to other humans.

It's speculative, whether an alien species, with a perceptual and cognitive system evolved entirely elsewhere under other pressures, would have an understanding that intersects with our subset of reality. I personally think it's unlikely. What that would mean is that we wouldn't be able to communicate, never mind trade technology and mathematical ideas.
So, the information that killed people was actually one that people overlook even in hindsight?

That puts the comments around here saying "what use can they make of X and Y?" on a new light.
