When any of the 3 output variables depends non-linearly of all 3 input variables that is not true.

Even on something as simple as a sphere, you can have a spherical triangle where one side is longer than the sum of the 2 other sides (e.g. when one side is on the equator and the 2 other sides go to one pole and the arc on the equator is greater than a half circle).

And you can map a (partial) sphere to a (partial) plane (mapping e.g. an equator segment and some meridian segments to straight lines, in order to map some plane triangles to some spherical triangles) and then use the distance in the plane as a difference function for pairs of points on the sphere.
Eh, I was hoping for an app mock-up equivalent of the daily WTF. Instead I got…the same old smartphone surrounded by a guy on a toilet, and a bent business card.
Phone company finally pulled fiber here where we used to only have cable. Now getting faster service for half the cost compared to Spectrum. So it does happen. Maybe they'll raise the price once they've gotten everyone to switch...
We see a similar effect in Europe, people live longer, and a large group is on pension, while retaining voting rights. This incentivize conservation of the status quo as we now have majority ownership of the societal future in the hands of a “rent-seeking owner class” that is not there to experience it.
Controversial as it may be, I’m thinking that voting should somehow be coupled to taxable contribution to the society. Pensioners, children and other unemployed must be protected by laws instead of direct political influence.

Comedian Nick Mullen has said the same, and he's had a life that's quite rough at times. It seems that being able to distract oneself from reality can be beneficial for a certain type of personality.
I've never in my life seen people feeding corn, maize, or soy that is human-edible to cattle. I can't imagine why you'd do that, either, because it's not very nutritious for them and there's a limitless amount of grazing.

Is it possible you're concentrating your view of livestock farming to the very artificial "feedlots" that they have in parts of the US where there's basically nothing for anyone to eat and no water?
Similar here, but I eventually realized it wasn't normal and wasn't who I wanted to be. I sought professional help. I learned Cognitive Behavioral Therapy, which I've internalized since I'm a programmer. CBT is like a language I can use to program myself. Just today I spontaneously told myself "Stop making things up! you don't need to come up with a reason or wild rationalization for every feeling"

I used to really resonate with the writings of Dostoyevsky and Melville. The opening paragraph of Moby Dick was a favorite:

“Call me Ishmael. Some years ago—never mind how long precisely—having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world. It is a way I have of driving off the spleen and regulating circulation. Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people’s hats off—then, I account it high time to get to sea as soon as I can. There is nothing surprising in this. If they but knew it, almost all men in their degree, some time or other, cherish very nearly the same feelings towards the ocean with me.”

I no longer feel grim about the mouth or feel damp and drizzly in my soul

Blockchains are an alternative pricing model for data hosting. Instead of a monthly bill, the transaction fee gets the data stored forever-ish. As scaling techniques are implemented, this makes more applications suitable for storing data on chain.

Yeah, agreed. It would be ideal to perfectly align your life passion with what you can get paid for, and a some people do manage to do that. It's not the only way though, despite what adherents of "success culture" seem to preach.

There is definitely a lot of work out there that needs to be done that isn't going to be anyone's passion. Still needs to be done, and it can pay well, and then you can do all kinds of fun things that you'd never be able to get paid for on the side.

A lot of people aren't monogamous in their passions either, which is kind of what you need to be in order to turn it into a career. Personally, I can't imagine every being so focused on one thing that it's all I'd want to do. I like my work, and I also love a lot of things that aren't my work.

People were being a bit stupid when they dogmatically stuck with the idea that "the earth is the center of the universe" and had to come up with ridiculously complex epicycles and systems of motion to describe the movement of the planets, when really if they had just change their assumptions and frame of reference, it was quite simple to see the planets were orbiting around the sun rather than in some weird epicycle involving the earth.

The impression a lot of people have about dark matter is I think similar -- dark matter / dark energy basically comes up as an explanation for why theory doesn't match what we observe. Thus a lot of people assume there is simply a more reasonable explanation, like a hidden variable we haven't considered, that would result in a theory that matches our observations. When I was in high school physics this was my assumption as well. I think if that were really the problem, though, someone would have solved it by now. That said, never underestimate an entire school of thought's inability to see things differently.
Do people argue that white people can't experience racism?!?

Downscale it. When I hit a point where I feel this is getting to much I radically downscale.

Just create a section in your to-do for future upgrades where you move huge topics until only your core idea is left again. In reality things may turn out different anyway, so find the MVP in your idea and bring it to market.

This is easier said than done, but reality is there is only so much one developer can do, and there is only so much motivation before you even bring it to market (feedback & cashflow help for motivation later)

I'm an astrophysicist. I love the idea of shaking up how we do science, but MOND models really aren't that compelling for a practicing scientist (I would love to be wrong). I periodically consider working a modified gravity project, but it never seems that interesting. Maybe I can lay out my personal impressions for you in a software analogy.

There are simple situations where physics can be reasonably distinguished from the noise. Think Newton watching an apple fall from a tree -- these are test harnesses with a debugger and careful control of the environment. There are also astrophysical situations where it's very hard to squeeze insight out of the chaos. Instead of looking at an apple to derive Newtonian gravity, imagine instead trying to figure gravity out by looking at a flock of birds. There are tricky things in the way of our understanding, like lift, turbulence, and biomechanics. We hope to understand the bad situations someday, but right now it's tough. Instead of the nice test harness, these situations are like debugging through cryptic, un-reproducible user complaints. What's their OS? Do they have the right drivers installed? Do they have all of their ports blocked for some reason?

In astrophysics, one nice system is the Universe at very large scales: echos of the big bang, the clustering of matter, and the formation of structure. We have great data these days about the large scales, and general relativity (GR) + dark matter (DM) is a very predictive model here. To our chagrin, the data always matches the theory. It takes 5 or 6 parameters, but the model has withstood huge improvements in data quality without really changing since the 90s. The other nice situation is the small scales like our own solar system: we can measure things extremely precisely at home, and again GR works remarkably well. There are a few other good situations involving objects like pulsars. Finally there are the hard situations: intermediate scales that involve the messy physics of star and galaxy formation. We don't really know how these processes work, but we can cobble together simple models with DM that sort of match the data.

Modified gravities in the literature always seem to act exactly like general relativity + dark matter in the clean, understandable situations, although it takes various contortions (screening) for these models to do this. Modified gravity models seem to only act differently in the bad arenas that are hard to understand, when there trickier issues like galaxy and star formation. That's deeply suspicious, and really weakens the value proposition of these alternatives. It's like introducing a software feature to fix something that never happens on the dev machine, based on mysterious user reports that you can only half decipher.

The remittance example doesn't even touch on use of stablecoins, which at the moment, are substantially easier to do international remittance with than bank deposits.

I wrote a list of other use cases where blockchain-based systems are clearly more efficient than centralized ones:

https://news.ycombinator.com/item?id=32393892

With respect to stocks, yes companies can maintain their own list of shareholders, but publishing that list to the blockchain standardizes the process of third party verification. The ERC20 token standard is widely adopted with tens of millions of installed wallets, and major blockchain explorers, that can interact with any ERC20 token contract. The activity the author briefly touches upon - trading - can also be made massively more efficient with a public blockchain. Being able to swap between any two tokens in the world using nothing more than Uniswap and your browser-based MetaMask wallet, is in most aspects a major UX improvement over the status quo, and thus it's perhaps not surprising that Uniswap has overtaken the top centralized exhanges in liquidity depth for several major trading pairs:

https://uniswap.org/blog/uniswap-v3-dominance

I suspect the author has never used stablecoins, or Uniswap, and if they had, they would come away with a completely different take on the potential utility of blockchain-based systems.

The big risk for blockchain based systems right now is the prospect of governments massively restricting internet freedoms to stop end users from transacting freely and privately without intermediaries.

The US Treasury placing an autonomous software program - Tornado Cash - on its list of sanctioned entities (a list intended to comprise people and organizations, not software), and thereby making it illegal for any American to interact with this smart contract, was the dramatic opening salvo in such a war on internet freedoms. To think that any US based person sending ETH to the TC smart contract from their MetaMask wallet, to gain privacy for their blockchain activity, now potentially faces years in the US prison system for that action, is extremely disturbing.

And this sort of draconianism is ultimately what the large public sector entities need to resort to keep their income-tax-dependent system alive in the age of distributed financial systems. The question is whether the public will accept their argument that crypto is so evil, that these sorts of curtailments of internet freedom are a price worth paying to stop it.
Rootless is definitely one of the major selling points for using podman over docker, especially for local development.
This, blockchain is crypto and crypto is blockchain. It is a clever way to bypass a central authority and trust the crowd.
Power ends up being bandwidth, but I don’t think you understand why.

A cellphone networks depend on proximity to a cell tower to alow frequencies to be reused across multiple cell towers. On top of this they also use a wide range of techniques to share each individual towers available bandwidth with multiple cell phones. But the most basic trick is signals get weaker with distance.

Starlink also uses distance as a satellite can only see a small fraction of the total number of ground stations. However, weaker from distance is indistinguishable from a weaker signal due to a phased array antenna pointing somewhere else, so they can in effect simulate more cells than they would have from proximity alone. On top of this they can use all the existing cellphone tricks to maximise bandwidth.

PS: Yes Starlink is limited to ~100 megabits per customer, but that’s vastly better than 1.5 Mbps DSL which is what many rural communities are stuck with.
Who is your audience? What is their background? What are you trying to achieve? What do you want audience to take away from your presentation?

> 1) Fairly well but without a deep audience understanding

Have some backup slides with details that you can flip to when you encounter keen audience willing to deep dive.

> 2) Fairly well with the audience hyper-fixated on the wrong detail

Don't address every detail in your presentation. Give your audience the chance to ask questions and lead them down the path you are well prepared for by leaving some gaps in details in that direction.

> 3) Fairly well with the audience hyper-fixated on the right detail

This is the ultimate goal of successful presentation.

> If so, why would this not be equally true for any digital game (see: any currently active MMO) with currency or items which can be sold between players in the exact same way?

It is already kind of true in non-blockchain games, but most of the accounting complexity is on the game company's end. This is described quite entertainingly in
"Accounting for SaaS and swords"
https://bam.kalzumeus.com/archive/accounting-for-saas-and-sw...

But it probably helps if trading in-game items for real money is not an officialy supported feature of the game, so only items you actually bought come with an extra service contract attached that the company needs to honor.
I’m not a fan of crypto currencies and markets, but is there not a use case for a distributed ledger? It is my understanding that that’s all a blockchain really is.
The article points out a „pro“ of returning a response in handlers - but fails to miss any cons.

However there are a few of them. One particularly important one is that the „return response“ variants lack extremely on the observability front - which then in the end leads to services which are hard to run in production.

Eg let’s say I want to measure in my handler what „last byte latency“ is - or at least when the handler pushed the last byte into a tcp socket. With the Go approach it’s not a problem - we can wrap the handler in another handler which does emit metrics.

With the „return response object“ it won’t work easily anymore. At the time the handler returns nothing actually has happened.

The same thing applies for eg tracking the amount of concurrently executed requests to understand resource utilization (and starvation). No issue with the Go variant - hard to do with „function as a service“.

It’s actually rather unfortunate that all Rust frameworks went down the „response object“ route and made it hard to add proper observability.
After solving problems like that for years, eventually almost anyone will develop such an ability, like one also would in regards to DB schema design, system design and picking architectures/design patterns.

The problem is that the majority of people simply don't spend time on issues like that, either in their day jobs or weekends/evenings. The closest you can get to things like that if you work in pretty boring domains, is having to pick between a Set or a Map for some data structure in the app. Or avoiding things like N+1 issues which have relatively little to do with algorithms and more in regards to how frameworks implement things.
Using the word 'operator' is a pretty obvious red flag.
Sure, that's fair.

I'm interested in a deeper dive; I think there's a lot to be learned about and said about WeChat, and as a developer I am interested, myself. It seems like Facebook definitely wanted to be that sort of service at one point with Libra, and I wondered if Musk had his eyes on turning Twitter into a platform that was enriched in the same way.
Does this also work for curved space time? Or is that type of curvature not going to help because it's relativistic? Or is the shape wrong? They mention that it doesn't work for cylinders.
> if you make it complex enough, you can engineer quite a few models that can predict natural phenomenon pretty well.

Well, yes. Next thing is to pick the easiest of these models: Occam's razor. But pondering whether such model is "correct" won't bring any further improvements.
The article states that only first party data collected by NYT is used for the model. They also use no demographic data.

It seems that the only data that leaves is your previously read articles.

Regarding what I have said, about the "non-Riemannian nature of perceptual color space" being known for decades, I have found an earlier paper with the same authors as the paper discussed here:

https://datascience.dsscale.org/wp-content/uploads/2019/01/C...

There, the authors themselves have written:

"Furthermore, human color perception is also non-Riemannian, due to the principle called diminishing returns [9]"

where the paper referenced as [9] is from 1968:

"D. B. Judd. Ideal color space: Curvature of color space and its implications for industrial color tolerances. Palette, 29(21-28):4–25, 1968."

Therefore the "non-Riemannian nature of perceptual color space" has been known at least from 1968, so whatever novelty is in the paper discussed here, this is not it, and the popular reporting about the paper is misleading.
My personal stance on why Blockchain is often not required is that a core feature of the Blockchain - decentralization( based on a lack of trust on a single entity) is not needed in the business world. In business, trust is an essential factor by which you pick your partners and suppliers, and often businesses reject cheaper offers in favour of business partners they know and trust based on past cooperations.
